CASH-REGISTER.

No. 915,090. Specification of Letters Patent. Patented March 16, 1906.

Application filed October 14, 1904 Serial No. 228,414.

To all whom it may concern:

Be it known that I, FREDERICK L. FULLER, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented a new and useful Cash-Register, of which the following is a specification.

The present invention has for its object the provision of a new cash register having a series of motor-driven indicators, a like series of banks of keys therefor which limit the extent of movement (to indicating position) of their respective indicators according to the keys depressed, a like series of detents which in normal position prevent movement of their respective indicators to indicating position but are withdrawn from such position by the depression of keys in their respective banks, and another series of detents normally locking all of the indicators against movement to indicating position and which are all withdrawn from such position by the depression of a special key; these several elements being so constructed and combined that on the depression of a key in one bank, or in each of two or more banks, followed by the depression of said special key, the indicator or indicators corresponding to such bank or banks will be released by both sets of detents and be driven to indicating position, in which position they are arrested by the keys depressed, while the indicators corresponding to those banks in which no keys are depressed will remain in their zero or normal positions. With -these mechanisms there are combined, among other things, registering mechanism for totalizing the amounts of the transactions, printing, wheels by which the several -transactions are printed on a strip of paper, and also a lever for restoring the indicators and printing wheels after one operation to their normal or zero positions before the next operation of the machine and which also serves to put under tension a spring operating, among other things, a printing platen, a drawer dock and a gong, and also operating a member held in normal position by a detent controlled by the special key aforesaid and which member controls the operation of a shutter mechanism, and when moved by said spring from normal position prevents withdrawal or reoperation of said special key (and therefore reoperation of the machine) until this member, the indicating wheels and printing wheels are returned to normal or zero position.

Fig. 18 is a view similar to Fig. 17 showing a modification for check printing; and Fig . 19 is a detail of the main shaft segment and ratchet arrangement in this modification.

Referring to said drawings, the several mechanisms of the machine are mounted upon a base A in the lower part of which is mounted a sliding money drawer B. The framework of the machine which supports the working parts, consists of three upright partitions C, D, E (see Figs. 2 and 3) fixed to the base and held in veitical position by tie-rods F, G, H, these working parts, partitions and tie-rods being inclosed by a suitable casing which is shown in Fig. 1.

The machine shown is of the double indication type, that is to say, one which simultaneously indicates sales at -an opening in the front of the machine and at a similar opening (not shown) in the rear of the machine. The indicators, consisting of wheels 62, for the front of the machine are located in the left hand half of the machine between partitions C, D, while the indicators also consisting of wheels 68, for the rear of the machine are located in the right hand half of the machine between partitions D, E; all of these wheels being loosely mounted on a shaft 63 extending entirely across the machine. In the right hand half of the machine is also located the registering mechanism, while outside . partition E is located a printing mechanism, inclosed by a supplemental casing T hinged to partition E. All of these mechanisms will be fully described hereinafter.

For the present the description will, for convenience and clearness, be mainly confined to the mechanisms contained m the left hand half of the machine. In the front of the casing, in this part of the machine, there is mounted a keyboard comprising six banks of push keys 23 and a single special key 42, which latter controls the a indicating, registering and printing operations, as will hereinafter appear. The keys in the bank at the left of Fig. 1, which are sometimes called system" keys, bear letters and abbreviations indicating, respectively, the salesmen and the character of the transactions, while the keys in the other five banks bear numerals representing amounts, in units, tens, etc. counting from the right of Fig. 1. The keyboard frame in which these keys are mounted is made up of a series (seven in number) of castings 14 (see Figs. 1, 4, 6 and 7) which are I-shaped in cross-section; or, in other words, have inner and outer flanges 17, 18 connected by a vertical web portion, parts of which maybe bored or cut out for the sake of lightness, as shown in Figs. 6 and 7. These castings 1 are held together, with the adjacent edges of their flanges 17, 18 in contact with each other; by tubes 15 through openings in the upper and lower ends of the several castings, and are secured in position in the machine by rods 16 passing through the tubes 15 and the ends of which enter openings in the vertical partitions C, D, in which they are rigidly held in any suitable manner. Suitable slots or openings are provided in the left hand edges of the flanges 17, 18 of these castings 14 for the reception of the stems 19 of the keys 23, and in the right hand edge of the flanges 17, 18 of one of these castings, namely, that to the right of Fig. 1, additional slots or openings are also provided for the reception of stem of the special key 42. The stems of all these keys are non-circular in cross section and the slots or openings therefor in the flanges 17, 18 are of like shape, so as to prevent turning of the keys while permitting endwise movement thereof is the slots or openings. One advantage of this construction of keyboard is that the several castings 14, with the keys 23, 42 properly positioned therein, may be easily and quickly assembled together upon the tubes 15 and the while then introduced bodily into the machine and secured in position therein, by the shafts 16.

As all of the keys 23 in the six banks representing amounts and also (in one bank) ,the salesmen and character of the transactions are alike in construction, a description of one bank and the keys therein will suffice for an understanding of the construction of all. Referring, therefore, to Fig. 6, (the keys shown in which happen to be the "system" keys shown- at- the left of Fig. 1) it will be observed that each of the castings 14 is arc-shaped, considered lengthwise, and also that the slots or openings in the flanges 17, 13 thereof for the key stems 19 are radial, so that the key stems 19 in each bank converge toward a common point, namely, a shaft 2 journaled in partitions C, D, E, and upon one end of which projecting outside the machine casing, is fixed an oscillatory lever 3, hereinafter more fully referred to, and which on each operation of the machine is given a complete reciprocation or oscillation first rearward and then forward. The stem 19 of each key, it will be observed, has coiled about it a spring 20, one end of which is secured by .a screw 21 to the stem and has its other end bearing against the outer surface of the flange 17, so that its tendency is to force the key outwardly. A pin 22 passes through and projects from opposite sides of the key stem 19 and normally abuts against the inner surfaces of the adjacent flanges 17 so as to limit such outward movement of the key. One projecting end of this pin 22 (namely on the left hand side. of the stem 19) coacts with the curved arm 30 of a detent 28 loosely mounted on a rock shaft 27 while its opposite end coacts with a key locking plate 12 loosely mounted on shaft 2, the construction and functions of which locking plate and detent will be hereinafter described in detail.

In the left hand half of the machine. there are provided for each bank of keys, in addition to the indicator wheel 62, and the locking plate 12 and detent; 28 just referred to, a gear 24 loosely mounted on a shaft 25 parallel to shafts 2 and 63 and meshes with pinion 61 fast to the side of the indicator wheel 62 so as to drive the latter to indicating position; a segmental entail gear 11 mounted loosely upon the shaft 2 and meshing with the gear 24; and a ring 47; one end of which is connected with the gear 24 and the other (as shown in Fig. 6) with a projection upon the hub of the locking plate 12. The gears 24 not only drive their respective. indicator wheels 62, but also simultaneously drive the companion or corresponding indicator wheels 68, and the registering and printing wheels, in the right hand half of the machine, as hereinafter described. The functions of each spring 47 are two-fold, namely, to drive the indicator wheel 62, through the gear 24 and pinion 61, to indicating position, (each indicator being thus provided with a separate or independent motor) and also to retain the locking plate 12 yieldingly in the depressed position in which it is shown in Fig. 6, in which position beveled portions of its periphery rest against the ends of the key stems 19, which thus limit the downward movement of the locking plate. Such movement of the indicator wheel 62 by its spring 47 is, however, prevented by the detent 28 heretofore referred to, which normally lies in the path of a pin 29 projecting from one side of the segmental gear 11, and further by a detent 26 (one of which is provided for each indicator wheel 62) which normally engages the gear 24. It follows, therefore, that, in order to secure such movement of the indicator wheel 62, both of these detents 28 and 26, which are independent of each other, must be moved. from their normal positions. This movement of the detent 28 is effected by the depression of a key 23, in the following manner. The curved arm 30, heretofore referred to, of the detent 28, it will be observed, extends along the left hand side of the stems 19 of the keys 23, as viewed from the front of the machine, and in alinement vertically with the ends of the pins 22 projecting from that side of the stems 19, so that, upon the depression of any of the keys 23 in the bank, such projecting end of the pin 22 thereof will engage and depress the arm 30 and through it rock the detent 28 upwardly and out of the path of movement of the pin 29 on the segmental gear 11, against the pull of a spring 31 fast to the casting 14 and, to the free end of the arm 30 (see Fig. 6). The key thus depressed is held in its depressed position and the detent 28 therefore held in its raised position out of the path of movement of the pin 29, by the locking plate 12, which, for this purpose, is provided, below its peripheral beveled portions before referred to; with notches or hooks 13 equal in number to the keys in the bank. Upon the depression of a key 23, that end of the pin 22 which projects froth the right hand side of the stem 19 will engage the beveled portion in line with it and thus rock the locking plate 12 upwardly against the pall of the spring 47 until the pin 22 comes in line with the undercut portion of the notch or hook 13, when the spring 47 will rock the plate 12 downwardly and thus cause said hook 13 to snap over the end of pin 22 and lock the key in its depressed position. With the key thus depressed, the opposite or left hand projecting end of the pin 22, being still engaged with the arm 30, will hold the detent 28 in its raised position out of the path of movement of the pin 29. Rotation of the indicator wheel 62 is, however, still prevented by the locking engagement, with gear 24, of the detent 26, which is disengaged therefrom by the depression of the special key 42 through connections which will now be described. It may be noted, in passing, that until such special key 42 is so depressed no indicating or registering operation takes place, so that if a salesman should discover that he had made an error in depressing a certain key 23, he may correct such error by depressing the proper key in the bank, when the locking plate 12, rocked upwardly by the second key depressed, will release the first one depressed and hold the second one in its depressed position. After such special key 42 is depressed, however, no such correction can be made as, by the depression of this key; locking devices; which will also now be described are thrown into engagement with the locking plate 12 so as to prevent movement thereof, and therefore the depression of any other key 23, either in the banks in which keys have been depressed or In those banks in which no keys have been depressed.

The detent 26 for each bank of keys and indicator wheel 62, its before stated, is fixed to the rock shaft 27 and this rock shaft 27 is, as shown in Fig. 7, provided with a curved arm 44 which enters a cut-out 4a in one side of the stem of the special key 42 So that when said special key is depressed it will through the arm 44, rock the shaft 37 and thereby raise or move from locking position, the detents 26 of all of the indicators and thus permit the springs 47, of those banks in which keys 23 have been depressed and detents 28, therefore, moved out of the path of the pins or studs 29, to rotate the indicator wheels 63 of those banks to indicating position; the special key 42 and the detents 26 being held in this position throughout the movement of the indicator wheels 62 by means which will presently be described. When the shaft 27 is thus rocked by the depression of key 42, other detents 26 thereon will enter notches in the upper ends of the several locking plates 12 (see Fig. 6) and thus prevent upward movement of any of those plates and therefore the depression of any keys 23. The movement to indicating position of the several indicator wheels 62 is limited by the keys 23 depressed in their respective banks, the stems of which, as will be observed on reference to Fig. 6, are of such length that when depressed their lower ends will project into the paths of movement of studs or pins 32 projecting laterally from the upper ends of the segmental gears 11. Of course, it will be understood that, as the several indicator wheels 62 are independently driven they, will be rotated to different degrees according to the keys depressed in their respective banks; for example, one may be arrested by the first key in one bank (counting from the top) if that is the key depressed, another by the third key in another bank, another by the fifth key in a third bank, and so on. It will also be understood that in those banks in which no key 23 is depressed the detents 28, controlled by such keys 23 still remain in the paths of movement of the studs or pins 29 of the segmental gears 11 of those banks and will, therefore, prevent rotation, by springs 47, of the gears 24 and indicator wheels 62 of those particular banks notwithstanding the detents 26 of those banks have, with the detents 26 of the other banks, been disengaged from the wheels of those banks by the rocking of shaft 27. When the indicator wheels 62 are thus propelled by their springs 47 to indicating position, as just described, the corresponding or companion indicating wheels 68 on the right hand side of the machine are also propelled to indicating position by the gears 24 of the respective indicator wheels 62, through connections consisting, for each gear wheel 24 and indicator wheel 68, of a pinion 65 meshing with gear wheel 24 and fast upon shaft 64 which extends entirely across the machine and has fixed to it a second pinion 67 meshing with a gear 66 (like gear 24) mounted loosely, upon the shaft 25 and meshing with a pinion 61 fast to the side o the indicator wheel 68. The several shafts 64 are arranged parallel to each other; the several pinions 65 thereon are arranged in different vertical planes relatively to each other for engagement by the gears 24 of the several banks as shown in. Fig. 3 , and the several pinions 67 thereon for driving the several indicator wheels 68 are likewise arranged upon the shafts 64 indifferent vertical planes relatively to each other, so as to mesh with the several gears 66 through which, and the pinions 61, they drive their respective indicator wheels 68. In other words, the arrangement of the shafts 64 and the pinions 65, 67 thereon is such that the units indicating wheel 68 (the first one to the left of the partition D, Fig. 3) will be driven from the gear 24 which drives the units indicating wheel 62 (the first one to the right of the partition D, Fig. 3); the tens indicating wheels 68 (the second one to the left of the partition D, Fig. 3) by the gear 24 which drives the tens indicating wheel 62 (the second to the right of the partition D, Fig. 3), and so on; the several indicator wheels 68 therefore being driven by the same means as and simultaneously with the indicating wheels 62 so as to make the same indication at the rear of the machine as that made at the front of the machine by said indicator wheels 62.

The special key 42 is held in its depressed position, and the detents 26 therefore held in their withdrawn positions, while the indicator wheels 62 are moving to indicating position; by a segmental gear 33 mounted loosely upon the shaft 2 and driven by a pinion 34 fast on a sleeve 48 on the end of a shaft 35 journaled in the partitions D, E (see Figs. 3 and 7). The sleeve 48 has fast to it one end of a spring 49 the other end of which is fast to a stud 50 on the partition D, and when turned to wind up this spring it makes a complete revolution on the shaft 35 and when turned in the opposite direction it gives the shaft 35 a compete revolution. The connections between the sleeve 48 and shaft 35 consist of a clutch member 51 spring pressed toward the sleeve 48 and having a pin and slot connections with the shaft 35. The adjacent faces of the sleeve 48 and clutch member 51 have inclined clutch teeth (see dotted t lines Fig. 3) which slip past each other when the sleeve 48 is turned to windup the spring 49 and interlock when it is turned in the opposite direction. The functions performed by shaft 35 when turned by sleeve 48 will be hereinafter stated. The spring 49 is normally under tension but rotation thereby of the sleeve 48 is normally prevented by a detent 36 fast to the rock shaft 27 and engaging a notch in the upper end of the segmental gear 33 (see Fig. 7). As the special key 42 is depressed, as heretofore described, for the purpose of withdrawing the detents 26 from locking engagement with the gears 24, it will, in order to so withdraw said detents, rock the shaft 27, through arm 44, and in so rocking the shaft 27 will raise and disengage the nose of detent 36 from the notch in the upper end of gear 33, thus leaving segmental gear 33 and the pinion 34 and sleeve 48 free to be rotated by tie spring 49, winch will so rotate these parts until the upper end of a cam 41 (which performs another function herein after stated) comes into contact with the upper edge of a segmental gear 37 rigidly fixed to shaft 2. As the spring 49 thus rotates the sleeve 48, pinion 34 and segmental gear 33, the untoothed peripheral upper portion of the latter will engage the nose of detent 36 and retain said detent in its raised position until the segmental gear 33 is rotated in the opposite direction and the nose of said detent 36 again drops into the notch in the upper end of gear 33. The rotation of the segmental gear 33 in this direction, to restore it to its normal position, is effected by the lever 3 and shaft 2 which, at the same time, restore, to normal or zero position, any indicator wheels 62, 68 that may have been moved to indicating position,, and also rock the several locking plates 12 so that any keys 23 which have been depressed will be released, these several operations being performed when the lever 3 is moved rearwardly from the position shown in Fig. 1, as presently described.

The additional function just referred to as performed by the cam 41 on the segmental gear 33, is that of controlling the movement of shutters 9-23 which normally close the opening go through which the indications on the indicator wheels 63, 68 are to be read. These shutters, as best shown in Figs, 3, 6 and 7, are connected together and loosely mounted, through arms upon the shaft 63. One of them, namely, front shutter 92, is provided with a pinion 94 concentric with said shaft and engaged by a toothed sector-on the upper end o? a lever 93 pivoted on shaft 25 and the lower end of which bears against the-periphery of cam 41 (see Fig. 7 ) in the normal position of segmental gear 33. When the lever is in this position both shutters 92 will be held between the indicator wheels fit and the front and rear Opening, respectively, in the casing through which the indication thereon are to be read. When, however; the detent 36 has been disengaged, by the depression of special key 42, from segmental gear 33 and the latter then rotated upwardly, as heretofore described, the cam 41 will pass out of engagement with the lower end of shutter lever 93 arid thus permit the front shutter 92 to be swung downwardly and the rear shutter 92 to be swung upwardly by gravity, (in which case the front shutter will be the heavier one) or by a spring, to expose through the front and read openings in the casing, the indications on the indicator wheels 62 68, respectively. The shutters 92 are, like the other parts moved during the. indicating operation, returned to normal position by the rearward movement of lever 3, through the connections which will now be described. It will be understood, however, that, following the usual practice in using cash registers, the shutters 92 and indicator wheels will remain in exposing or indicating positions until the next sale is to be indicated and registered and that it is just previous to this next sale that the lever 3 is thus moved rearwardly, to destroy the indication of the previous sale and return the indicating-mechanism to normal or zero position, and then moved forward to the normal position in which it is shown in the drawings. Where, therefore, the expression "normal position is used in this description and in the accompanying claims, it will be understood that by it is meant this position of the parts.

Referring particularly to Figs. 5, 6 and 7, it will be observed, that the shaft 2 carries a rod 39 secured at one end in a crank arm 38 fixed to the shaft 2, preferably .by being cast integrally with the hub of the segmental gear 37, and at its other end in a ratchet segment 4 fixed to .the opposite end of said shaft. This rod 39 extends behind or beneath all of the segmental gears 11 so that when the lever is moved rearwardly, thereby rocking the shaft 2 about one quarter of a revolution, the roil-39 will, in moving from the position in which it is shown in full lines in Fig. 6 to the position in .which it is shown in dotted lines in said figure, by engagement with projections; 40 integral with segment gears 11, pick up the several segmental gears 11 and restore them to normal position, and at the same time, through them and the gears 24, also restore to normal or zero position all of the indicator wheels 62, 68 that may have been maven to indicating position. As the shaft 2 is thus rocked rearwardly by the lever 3, the segmental gear 37, moving therewith, will, because of the engagement of its. forward Or upper edge with the upper end of the cam . 41, rotate the segmental gear 33 rearwardly to its normal position (shown in Fig. 7), .a , when the segmental gear 33 arrives. in this position, a spring 27b connected at one end with the .partition D and at its other end with an arm 27, fixed to the rock shaft 27, will rock said shaft 27 so as to depress the nose of the latch 36 into reengagement with the notch in the upper corner of the segmental gear 33. The segmental gear 33, it will be observed, as it is thus restored to normal position, will give pinion 34 and sleeve 48 a complete rotation and thus put the spring 49 under tension for the next operation of the mechanism. As the shaft 27 is thus rocked by the spring 27-, the several detents 26, fixed thereto, will also be. depressed into reengagement with their several gears 24 thus locking the indicators 62 in the normal or zero positions to which they have been returned by the rod-39; the several locking detents 26 will be withdrawn from the notches in the upper ends of the locking plates 12; and the arm 44 fixed to the shaft 27 will also be rocked outwardly or upwardly and thus restore the special key 42 to its normal, projected position in which it is shown in Fig. 7. This outward movement of the special key 42 may be aided; if desired, by an additional spring, having one end connected with the lower wall of the cut-out 43 in the key stem and the other with the outer flange 18 of the casting 14 in which said special key is mounted.

The rod 39 has a slight amount of movement upwardly beyond the position in which it is shown by dotted lines in Fig. 6 so that it may engage the lower edges of the locking plates 12 and rock. said plates upwardly to release therefrom any of the keys 23 which may have been depressed and which are then moved outwardly by their springs 20. When the lever 3, and rod 39 are then rocked in the opposite direction, or returned to normal position, (as they must be to permit the machine to be again operated) the several locking plates 12 will resume the locking positions, with relation to the keys 23, in which the locking plate 12 is shown in Fig. 6, ready to engage the keys 23 depressed for the next sale.

It is desirable that some means should be provided for preventing the rearward movement of the handle 3, just described, before the special key 42 has been depressed sufficiently to release the detent. 36 from engagement with the spring actuated segmental gear 33 and the detents 26 from the gears 24, and to also prevent such movement of the lever 3 and shaft 2 while the indicating mechanism is being propelled to indicating position. For these purposes the cut-out 43 in the stem of the special key 42 is of greater width (considered lengthwise of the stein) than the arm 44, the inner edge of which is normally engaged by the lower wall of the cut-out 43, as sown in Fig. 7; so that, when depressed, the key 42 has a certain amount, of play relatively to the. arm 44 before it engages therewith for the purpose of de pressing it. The stem of the key 42 also is provided at its lower end with a channel 46 which is adapted for the passage through it of a .rail 45 projecting laterally. from one face of the segmental gear 37. Because of the play provided between the cu-out 43 and the arm 44 as the key 42 is depressed, said key must, in order to depress the arm 44 so as to disengage the detent 36 from the se mental gear 33 and detents 26 from the gears 24, be so far depressed that the channel 46 in the lower end of said key stern will pass beyond or inside the plane of rail 45, with the result that the solid portion of said key stem above the channel 46 will be in line with the rail 45 and thereby prevent movement of the lever 3 and shaft 2 until, on the removal of the finger of the operator from the special key 42, said special key is moved outwardly so that the lower wall of the cut-out 43 therein will engage the lower or inner edge of the arm 44 at which time the channel will be in line with the rail 45. When the channel 46 is thus in alinement with the rail 45, it will permit the , passage through it of the latter, so that the handle 3 and shaft 2 may be moved rearwardly. When the rearward movement of the handle 3 is completed, the rail 45 will have passed out of the channel 46 so that, when the shaft 27 is rocked by the spring 27a, as heretofore described the special key 42 may. be moved from its depressed position to the projected position m which it is shown in Fig. 7. Such premature rearward movement of the lever 3 is also prevent d by sleeve 48 and shaft 35 through a locking device controlled thereby and engaging the shaft 2. This locking de vice consists of a pivoted bell-crank lever 53, the upper end of which is backed up by a spring 53 tending to force it toward the 1 shaft 2 arid into engagement with a tooth 54 thereon, arid the lower end of which is normally engaged by a cam 52 on -shaft 35 which, in the position. of rest of said shaft, holds the opposite end of the lever 53 out of engagement with the tooth 54 (see Fig. J) . This shaft 35, it will be remembered; is given a complete revolution by sleeve 48 (through clutch 51) when driven by spring 49, this taking place, as before described, when detent 36 is .disengaged from the notch in segmental gear 33. As soon as the detent 36 is thus disengaged from the notch in the upper end of segmental gear 33 and the rotation of sleeve 48 and pinion 34 begun by spring 49 the shaft 35, rotating with said sleeve and pinion, will move. its cam 52 from under the lower end of lover 53 and thus permit the spring to throw the upper end of said lever into engagement with the tooth 54 on shaft 2, thereby preventing rotation of sail shaft 2 until said shaft 35 has made a complete revolution, when cam 52 will reengage the lower end of lever 53 and withdraw the upper end thereof from engagement with tooth 54, when the lever 3 and shaft 2 will be free to be rocked rearwardly.

During the revolution of shaft 35 it per forms the additional functions of withdrawing the lock 56 from the money drawer B and tripping the gong hammer, which is in the form of a bell-crank lever 59. The first of these functions is performed by a cam 55 on shaft 35 which, when said shaft, nears the completion of its revolution, engages one end of a bell-crank lever 57 fixed to, a shaft 108 and, rocking the other end thereof upwardly, withdraws the bolt 56 from, the drawer. The second function is performed by n cam e8 on shaft. 35 which, when said shaft, has about coin feted its revolution, engages and trips the lever 59 causing it to strike the gong beneath it. his, hammer-lever shaft 108 is journaled in partition E, with one end protecting into the casing I, and, as will herein after, appear, assists in the operation of the printing mechanism. Means are also pro vided for preventing the return of the lever 3 after a partial movement thereof in either direction. The moans provided for this purpose (see Fig. 5) consists of the ratchet segment 4 here-in-before referred to, having two sets of reversely arranged ratchet teeth 6 with a projection .5 midway between them, and a double-ended pawl 7, pivoted at 8, and engaging these teeth. The pawl 7 is pro vided near one end with a lug 9 of wedge shape against the upper and lower aides of which a spring pressed dog ,10 is adapted to bear for the purpose of maintaining the pawl 7 in engagement with one or the other set of ratchet teeth 6. When the operating handle 3 is thrown rearward the forward end of pawl 7 being then in engagement with the forward net of ratchet teeth 6 will prevent any forward movement of the lever until said rearward movement is completed.. When such movement is completed the projection 5 on ratchet segment 4 will engage the forward point of the pawl 7 and force it downward and thus raise the rear point of the pawl, the lug 9 then forcing the dog 10 backward until the upper end thereof snaps under the lug 9 so as to hold the rear point of the. pawl in engagement with the rear set of ratchet teeth-6 throughout the forward or return movement of the lever 3, at the end of which the projection 5 will again reverse the pawl 7.

The registering mechanism will now be described.

For the five banks of keys bearing numerals there are five register wheels 74 hearing numerals representing amounts in units, tens, etc. counting from the right in Figs. 2 and 11, there being no register wheel for the sixth or "system" bank of keys. The units register wheel 74 at the extreme light of Figs. 2 and 11 is operated by the gear 24 of the units indicating wheels 62,68; the tens register wheel (which is next in order to the units register wheel) by the gear 24 of the units indicating wheels 62, 68; and so on. In addition to these five register wheels, two others, 90, 91, are provided, shown at the left in Figs. 2 and 11, to which amounts are carried from the last of these five register wheels. The five register wheels operated by the gears. 24 are identical in construction, and the connections by which they are driven from their respective gears 24 are also identical. They, as well as the two additional register wheels, 90, 91 referred to are all mounted loosely on a shaft 71 journaled in the frames D, E, and each has two sets of numerals from O to 9 arranged one behind the other on its periphery. Each is also provided with a ratchet 73 engaged by a spring pressed pawl 72 pivoted in the side of a gear 70 also loosely mounted on shaft 71. end. by which the register wheel is rotated when registering.. The gear 70, which has twenty teeth to correspond with the twenty numerals on the register wheel 74, is driven by the shaft 64 and gear 24 (of the bank to which the register wheel corresponds;) as the latter drives its. indicator wheels 62, 68 to and from indicating position, as before described. The connections through which the gear 70 is so driven consists of the shaft,64 (driven by gear 24 through pinion 65), a pinion fixed to said shaft intermediate its pinions 65; 67, and a gear 69 mounted loosely on shaft 25 and meshing with said gear 70, When the shaft 64 is rotated by gear 24 to move its indicator wheel 68 to indicating position, the gear 70 will be rotated thereby in the direction of the arrow Fig. 15 and through its, pawl 72 and the ratchet 73 rotate register wheel 74 a distance corresponding to the movement of the indicator wheel, thus registering the amount indicated by the latter. As the shaft 64 is turned in the opposite direction to return indicating wheel 68 to zero or normal position, guar 70 will be rotated in the opposite direction to that indicated by the arrow in Fig. 15, and its pawl 72 will slip idly over the teeth of ratchet. 73, leaving the register wheel 74 in the position to which it liar been moved. The register wheel 74 is held in this position by. a spring escapement 76 (see Fig. 9) pivotally mounted on shaft 25, and which also prevents overthrow of and accurately positions the register wheel. As the indications on-the register wheels are reach from the front of the machine and not (as is the case with the indicating wheels 68) from the rear, it will be understood that the gear.69 at the left of Fib. 3 is the one which operates the units register wheel 74; the next gear 69 to the light thereof the one which operates the tins register wheel 74, and so on.

The register wheel shaft 71, which, as before described, is journaled in the frames D, E, is normally prevented from rotating in the direction in which the register wheels rotate by an arm 117 having a tooth entering a recess in the hub of a ratchet 119 fast to the shaft 71, as shown in Fig. 10, and rotation of said shaft .71 in the opposite direction is always prevented by an arm 120 engaging, the teeth of said ratchet 119; both of these arms 117, 120 being mounted upon the shaft 25. Means are provided, and will be hereinafter described, for withdrawing the arm 11.7 from engagement with the recess in the hub of ratchet 119 so that the shaft 71 may be rotated by hand (for which purpose it may be provided with a knob or other suitable device at its right hand end) in -are direction in which the register wheels are rotated. during the. registering operation so as to reset said register wheels to their zero positions whenever the proprietor or user of the machine, desires to do this: The means whereby, on the rotation of said shaft 71 in this direction, said register wheels are returned or re-set to their zero positions, consist of a longitudinal groove or slot 78 on the shaft 71, which, when said shaft is rotated, as just described, will engage spring, pawls 77 carried by the several register wheels, as shown in Figs. 12 to 14, and rotate said register wheels to their zero -positions. As the register wheels, in the registering operation are rotated on the shaft 71 these pawls 77 will bear upon the surface of said shaft and pass the groove or slot 78, but when the shaft is rotated said groove or slot 78 will, by engagement with the spring pawls 77, pick up the several register wheels and rotate them to their zero positions.

The registering mechanism also includes devices for carrying amounts from one register wheel 74 to the next higher register wheel, which devices will now be described. Upon a shaft 79, parallel to the shaft 71, are loosely mounted five sleeves 80 (one for each, of the five register wheels 74 driven by, the shafts 64) and. each of these sleeves as provided at its right hand end with a star wheel 81, .and at its left hand end with a star wheel 82, both. rigid with the sleeve.. The star wheel 81 is adapted to be periodically. engaged and rotate together with sleeve 80, by a pair of fingers 85 projecting from diametrically opposite points of a sleeve or hub at the left hand side of one register wheel 74, . while the latter (viz: the star wheel 82) is adapted to be engaged and rotated, with sleeve 80, by a cam 87 on a shaft 88, and when so rotated to engage a gear. 75 upon the right hand side of the next higher register wheel 74 so as to. rotate the latter. one tooth or numeral. Shaft 88 is provided with five cams 87, one for each of the sleeves 80 with its pair of star wheels 81, 82. The star wheel 81 has -four teeth and star wheel 82 a like number of teeth, while sleeve 80 is provided circumferentially with four .pairs of notches 84, 86, adapted to be engaged by a spring detent 83 fast to the tie-rod H. Normally, as shown in Fig. 16, the detent 83 is in engagement with one of the notches 84I and when the sleeve 80 is in this position one of the teeth of the star wheel 81 lies in the path of movement of the fingers 85 of the lower register wheel 74.

When the lower register wheel 74 has been rotate d nine teeth or numerals arid is being moved from this position to or beyond the "0" mark which follows, one of its fingers 85 will engage that tooth of the star wheel 81 which then happens to be in its path of movement and rotate said star wheel, from the position shown. by full lines to the position shown by dotted lines in Fig. 16, thus rotating the sleeve 80 and the star wheel 82 at the left hand end thereof. When the sleeve 80 has been thus rotated, the detent 83 will drop into the( rear notch 86 and retain the sleeve and the star wheels. 81, 82 in the position to which they have been rotated or set; this notch 86 being made somewhat deeper than the notch 84 so as to retain the sleeve and its star wheels firmly in this set position against any tendency to displace it due to jar or vibration of the machine: When the sleeve 80 has been moved to this position, a tooth of the left hand star wheel 82 will be brought into the .path .of movement of its cam 87 on the shaft 88, so- that when said shaft is rotated in the direction of the arrow, Fig. 16, thus cam, engaging this tooth of the star wheel 82, will further rotate the sleeve 80 and its star wheels the balance of a quarter revolution with the result that the next following tooth of the star wheel 82 will engage the gear 75 of the next higher re register wheel 74 and thus rotate said gear wheel and. register wheel a. distance equal to one tooth

or (file numeral. The five cams 87 are ar- ranged spirally upon the shaft 88 so that when said shaft is rotated the cams 87 will operate successively; so that the sleeve 80 and star wheel 82, which carry from the units register wheel to the tans register wheel, will first be operated, then the sleeve 80 and star wheel 82 which carry from the tens register wheel to the hundreds register wheel, and so on. This successive operation of the sleeve 80 and star wheel 82 provides for the carrying from one register wheel to the next highest one, not only in those cases where a register wheel is moved from "9" to "0" by the registering operation through its gear 70, but also in those cases where a register wheel is so moved during the; operation of carrying Fur example, it the star wheel 82 of the units registering wheel be- operated by its-care 87 to carry one to the tens registering wheel, and it should then happen that the movement of the latter is from "9" to "0 ", one of its fingers 85 will engage and rotate the star wheel on the sleeve connecting it with the hundreds registering wheel and thus position the star wheel 82 thereon for engagement and rotation. by the next cam and consequent engagement with, and operation of, the gear 75 of the hundreds registering wheel.

The shaft 88 is rotated in both directions by the lever 3, through the shaft 2 and segmental gear 37,. which latter, as best shown in Fig. 7, meshes with a pinion 89 fixed to the left hand end of the shaft 88. As the lever 3 is rocked rearwardly, the segmental gear 37 will rotate the shaft 88 in the direction indicated by the arrow in Fig. 16, and the cams 87, thereon will successively engage the star wheels 82 that have been set for such engagement, or become so set during the carrying, as just described. When the lever 3 .is rocked forward, said shaft 88 will be rotated in the opposite direction, the cams 87 then passing under .the teeth of star wheels 82 without engaging them, and the several star wheels and their sleeves 80 being. then in normal position, in which position they are held by the engagement . of the spring detents 83 with notches 84 on said sleeves (see Fig. . 16).

Thus far- the description of the carrying devices and the carrying operation has been limited to the five register wheels which are actuated by the gears 24 and shafts 64, as just described, except that it has probably been observed that the sleeve 80 with its star wheels 81, 82 which is set by the fifth register wheel 74, i. e., that one of the five which has the highest denomination, carries from that wheel to the sixth register wheel 90 (counting from the right) , shown in Fig. 11. For the purpose of carrying from this latter wheel to the seventh or last wheel 90 of the set (shown at the extreme left in Fig. 11), any suitable form of carrying device may be provided, such, for example, as the familiar form of carrying device sown, consisting of an idler pinion 91 mounted loosely on the shaft 79 (see Fig. 9) and which is periodically engaged and rotated by a pair of diametrically opposite teeth on the sixth register wheel 90, and as the latter moves from "9 " to" 0" and when so rotated, in turn rotates the seventh or last register wheel 90 one numeral through a pinion fast to said register wheel and with which said pinion 91 meshes.

Referring now to Figs. 2, 3 and 17, the printing mechanism will be described. This consists of a series of printing wheels 95, mounted loosely on the end of the shaft 25 projecting beyond partition E, a platen 100 coacting therewith to cause the type thereon to print upon a strip or tape 99 (the matter printed on which is to be read-from the front of the machine), and an inking roller 114 for inking the type on the printing wheels; all these parts being located in the casing I at the right hand side of the machine. There are six printing wheels 95, one for each of the five banks of keys representing amounts- and . the remaining one for the bank of " system" keys bearing letters and abbreviations. They are all alike in construction and are all operated by the gears 24. of their respective key banks, the connections through which they are so operated consisting of the shafts 64 rotated by gear 24, and pinions 96 fast to the right hand ends of said shafts (viewed from the front of the machine) and meshing with gear teeth with which their respective printing .wheels are provided for a portion of their peripheries. The pinion 96 at the extreme Left of the rear elevation, Fig. 3, actuates the units, printing wheel 95, .the next one actuates te tens printing wheel, and so on, while the one at the extreme right of Fig. 3 actuates the "system" printing wheel 95.

Each type-wheel 95 is. provided with ten type arid, as the indicators 62, 68 are rotated to indicating position, said type-wheels will be correspondingly rotated to bring to the printing point. the type corresponding to the indications made by the indicator wheels, retaining this position until the indicator wheels are returned to normal or zero position. when they are also returned to normal position by the shaft-64 through pinions 96. The platen. 100 is carried in the end of an arm 97 loosely mounted on-a stud 98 projecting from the partition E, said arm having connected with it on the opposite side of said stud, one end of a spring 106, the other end- of which is connected with the partition E and the function of. which is to propel the platen 100 against the printing wheels and paper at the proper time. This spring 106 is put under tension to rock the. arm 97 arid cause its platen to strike. against he paper and type by a cam 104 fast to shaft 2 and which, as lever 3 and said shaft 2 are rocked rearwardly, :as heretofore described, engages a projection 105 through which it depresses the arm 97 to the position shown in rig. 17, and puts spring 106 under tension. This rearward movement of. lever 3 and also its forward or return movement to the position shown in the drawings, it will be remembered, takes place between sales, and, according to the usual practice, just before what may be termed the next sale is to be indicated and .registered, as previously explained. The arm 97 is. retained in this depressed position, with the spring 106 under tension, by a spring-pressed pawl 107, the upper end of which engages a projection 109 on the arm 97. This pawl is mounted on the end of the drawer-lever shaft 108, previously referred to, with a limited amount of looseness or play circumferentially of said shaft (as shown in Fig. 17) permitting movement of said pawl, by its spring , relatively to shaft 108 into engagement wit the projection 109 on- arm 97. When, as heretofore described, the drawer-lever 57 is mocked by cam 55 on shaft 35 to withdraw bolt 56 from the drawer B, said drawer-lever 57 will rock shaft 108 , with which it is rigidly connected, and, engaging the pawl 107, will move the latter, against the pull of its spring, out of engagement with. projection 109. The spring 106 will then propel the arm 97 upwardly and cause the platen 100 carried thereby to strike against the paper and the type on the printing wheel, and- thus effect the printing. As the arm 97 thus flies upward, a spring 111 thereon will strike against a stop 112 on the partition, first stopping the upward said arm and then moving it downwardly slightly so as to withdraw its platen 100 from the, type, in which position it will remain until, just before the next sale, the lever 3 is moved rearwardly and said arm 97 moved downwardly thereby, as just described.

The shaft 35 is geared to a governor 60 which retards its movement when propelled by its spring 49 so that the shutter lever 93 will be released by segmental gear 33, the gong lever 59. trip tripped and drawer-bolt 56 , withdrawn from the drawer after the movement of the indicator wheels 62, 68, to indicating position and of the type wheels 95 to printing., position has been completed; the withdrawal of pawl 107 from engagement with projection 109 on arm 97, following the withdrawal of drawer .bolt 56, .so that the spring 106 may propel said arm 97 upward for printing;

The inking roller-114 is, as will be observed on reference to Fig. 2, of a width sufficient to ink the type of the several printing wheels 95. It is made. op of a metal sleeve, revolving freely on a spindle fixed a an arm 118, and a plurality, of inking rolls revolving freely on said sleeve and bearing against the type of the several printing wheels. The arm 113 is mounted, concentrically with the printing wheels, loosely on shaft 25 and is connected, by. a pin and slot with the platen carrying arm 97, so that as the latter flies upward, as just described, to effect the printing, the arm 113 will be swung to the right in Fig. 17, thus causing the inking roller 114 to sweep over the type of the several printing wheels before the platen 100 reaches the printing point. As the arm 97 is then de pressed by its spring 111 and later by the rearward movement of lever 3 and rocking of shaft 2 and cam 104 thereon, the arm 113 will be moved upwardly to the position shown in Fig. 17. The paper strip or tape -is introduced into the machine in the form of a roll 99, mounted loosely on stud 98 on which the platen carrying arm 97 swings, and is led over the platen 100 and thence to a take-up roller or drum 101 carried by arm 97 and provided with a pawl and ratchet 102 which prevent unwinding or back-winding of the paper. A weighted, arm 103 pivoted in arm 97 rests upon the roll of paper 99 and keeps it under, proper tension.

The paper strip is unwound from .the roll 99 by a spring-pressed pawl 110 pivoted in partition and which, on the downward movement, heretofore described, of platen-carrying arm 97, takes in behind a tooth of ratchet on take-up roller or drum 101 and, on the upward movement of said arm 97, rotates said roller or drum one tooth; thus bringing afresh portion of the paper strip of tape over platen 100 in position to take the next impression from the type on the printing wheels.

The machine is also provided in the front casing with a glass covered opening through which to read the indications on the register wheels 74 and between this opening and the register wheels there is normally interposed a shutter 115 .loosely mounted, by arms, on the register-wheel shaft 71 (see Figs 2, 5, 9, 10 and 11). A lock 116 is provided for operating this shutter and when this lock is turned by its key, the arias .are rocked on shaft. 71 so as to swing shutter 115 rearwardly or to the right of Fig. 10, and thus expose the register wheels through the opening. The operation of this lock also raises a spring latch 121 engaging a catch (not shown) on the hinged casing I and passing through a slot 122 in partition E, said latch, when engaged with said catch, Docking casing I to the main casing of the machine. When the casing I is unlocked by the disengagement of this latch and catch, it may be swung open, so that the paper tape and printed matter thereon -may be inspected, and if necessary, . removed and replaced by another tape.

A third function performed by the opera tion of lock 116 is that of disengaging arm 117 from recess 118, thus permitting rotation of shaft 71 by means of a knob or otherwise, for the purpose of engaging its longitudinal groove or slot 78 with the pawls 77 of .the several register wheels and restoring said wheels to zero, as heretofore described; the end. of shaft 71 being accessible for this purpose when casing I is opened.

The machine is, as shown in Fig. 5, also provided with a pawl controlled by a keyoperated lock and which when, moved by the bolt of said lock to the dotted position shown in Fig. 5, engages the rear ratchet 6 of the segment 4 and prevents operation of the machine; this lock being provided -for use by the proprietor or user of the machine when leaving the store or the machine, so that the machine cannot be operated in his absence.

As the operation of the several mechanisms of this machine has been stated in the description of the construction of said several mechanisms; a general statement of the operation of the machine is unnecessary.

In Figs. 18 and 19 I have illustrated a check printing attachment instead of the tape, as in the preceding figures. In this construction are shown a dater 123, a feeding drum 124, and a chute 125, leading to the platen. In this case the feeding drum and dater are revolved in a backward movement by the handle 3 through the ratchet shown in Fig. 9, end the segment on the main shaft 2, .the -strip being cut by a knife 126 when the arm 97 comes down. In all other particulars the mechanism is the same as in the preceding figures of the drawings.
