If part of the fluid is bled off from the normal path to the openings and is permitted to discharge into a pan or receptacle or against moisture sensitive means such patents will not be found in subclasses 63+ but will be found in subclasses 67 and 68.

(2) Note. For this and the indented subclasses, a system must at least be disclosed as a sprinkler apparatus with control means being responsive to a condition brought about by use of the said sprinkler. If there is no clear disclosure that the moisture sensing means is positioned within and senses the moisture in the area served by the sprinkler system, it is assumed that the means senses and responds only to atmospheric rainfall. An apparatus with a means sensing atmospheric rainfall for control of a sprinkler or a spray outlet is classifiable in other appropriate subclasses in Class 239 if the sprinkler or spray outlet is positively claimed and in Class 137 if a mere fluid system is claimed.

(1) Note. The additional control means may be either manually or automatically operated. In those systems including a timer or clock mechanism, such mechanism is the overriding second control means since it will not permit the flow of fluid to the sprayers until the selected time is reached, or regardless of the demand placed upon the system, or it will positively shut off the fluid when the set time period has elapsed, also regardless of the fact that additional demand is required externally of the system.

(1) Note. For classification herein there must be claimed as control means something more than the mere limits defined by traversing guide, track or tethering means or the paying out or ultimate drag of a hose connected to supply means, i.e., there must be something in addition to the necessary spraying organization which is selectively-variably imposed on the system to control the flow.

(1) Note. The flow establishing means may be either a valve or a pump means and the flow may be either fluctuating or intermittent.

98	. Plural outlets with abutment operated flow diverter :

This subclass is indented under subclass 97. Apparatus which include a plurality of distributor members and valve means actuated by engagement of said valve means with a member which is fixed relative to a support for said member in order to transfer the flow of fluid from one member to another.

(1) Note. The plural outlet members usually constitute oppositely directed reaction nozzles which discharge alternately in order to impart oscillation to said apparatus.

650	CONTAINER FOR NON-FLUID MATERIAL, AND SCATTERING MEANS:

This subclass is indented under the class definition. Apparatus comprising means for holding a supply of material, other than a fluid or a slurry, and means for strewing such material in the form of relatively small solid pieces over an extended area on a surface.

(1) Note. The phrase "extended area" means an area larger than that which would be covered if the material were merely dropped from the supply holder. An area caused by the motion of a supply holder traveling over the surface to be strewed and merely dropping material from the supply holder is not considered an extended area for purposes of this classification. See Class 414, Material or Article Handling, subclasses 467+ or Class 222, Dispensing, subclasses 608+ for such devices. This distinction becomes very tenuous in some cases since, for example, a conveyor operating at high speed and unloading a wagon will cause a strewing action over an extended area. The line between the definition of this subclass and the art in Classes 414 and 222 as to containers with unloading means is that where a discharge assistant or unloading device of a type found in such classes is claimed and the disclosure is not limited to, or a claim not directed to a strewing action, such as may be brought about by conveyor high speed operation, classification is in Class 414 or Class 222, but where the disclosure is clearly limited or a claim is directed to a substantial strewing action in such device additional to that caused merely by motion of the supply holder over the surface to be strewed classification under the definition of this subclass results from the claiming of some means for strewing comprising a moving device which is recognizable as additional to a dispenser with a discharge assistant or a vehicle with an unloading means. In some instances the strewing over an extended area is caused by a deflecting means or diverging nozzle arrangement or the like which causes material issuing from an opening in the supply holder to spread out over an area wiser than that of the opening. The extended area in some cases may be little more than a line in the absence of motion of the supply holder over the surface to be strewed.

(2) Note. In accordance with the line between the subject matter of subclass 650 and Class 222, as indicated in (1) Note, subclass 650 takes apparatus in which the particulate material is strewn in the ambient so that it falls in an area which is substantially more extensive than that covered by merely dropping the material from an opening of a stationary or ambulant dispenser. Where, however an opening is, or openings are, formed in a wall of the supply holder and strewing is effected by movement of the supply holder classification is in Class 222. See Class 222, subclasses 160+ and 565, for examples of such strewing. Further, for classification under the definition of subclass 650 rather than in Class 222 the means for strewing must be positively claimed. When such means comprises a relatively moving element, such as a rotating distributor the reference to it in a claim may be in the broadest terms. When, however, the strewing means comprises a terminal outlet, such as a nozzle, a mere broad description of such nozzle will not serve to cause classification under the definition of subclass 650; the recitation of the nozzle in a claim must be specific and its strewing function must be clearly indicated by the disclosure as being due to the specifically recited structure of the nozzle, rather than due to ambient wind conditions or the nature of the material dispensed, such as fine powder. The subject matter of subclass 652 forms an exception to this line, however; that subclass constitutes an art collection of devices for strewing by direct hand manipulation. In close cases it is very difficult to determine just what constitutes the opening of the dispenser and also what constitutes an added feature of the dispenser for spreading material, so that placement of a patent as an original will depend on the judgement of the classifier and the placement of like art. Usually a discharge assistant which is in a container or extends from the container partially thru an opening is not considered to cause classification under the definition of subclass 650 unless the special circumstances mentioned in (1) Note are present.

(3) Note. Included in this definition of "strewing means" is a pipe having longitudinally spaced apertures or perforations.

(4) Note. Excluded under this definition is a flowable slurry of solids in liquid; this is considered a fluid and is classified in another section of the class. Included under this definition is material comprising solids with a small amount of liquid mixed therewith, but not sufficient to permit flow.

(5) Note. A disclosure of a device for strewing or scattering or particulate matter should not be found as an original in any subclass following this group unless combined with means for sprinkling, spraying or diffusing a fluid (e.g., subclass 336) or as a nozzle, per se, disclosed for discharging fluent solid, but also capable of use with a fluid.

651	. With loading or loading facilitating means:

This subclass is indented under subclass 650. Apparatus comprising a means disclosed as used for or aiding in the operation of, placing the material into the supply holder.

(1) Note. Merely positioning the supply holder for receiving the material from a source by gravity does not qualify as loading or loading facilitating means under this definition.

652	. Scattering by direct manual movement:

This subclass is indented under subclass 650. Apparatus in which the strewing means comprises a member from the end of which the material is strewn, the member being disclosed as intended to strew material by being manually moved relative to the body of a person manipulating the member, movement being caused without the use of a mechanism comprising relatively moving parts.

(1) Note. The member, of and by itself, is not necessarily a strewing means under the definition of subclass 650. The manually caused motion to cause strewing is sufficient to qualify under the definition. The manual motion must be intended to be of considerable extent to effect a substantial strewing.

Apparatus comprising a means, other than a handle, for supporting the apparatus on the body of a person or animal, or a means, such as a special contour for the supply holder, related to the function of supporting the apparatus on the body of a person or animal.

654	. With means generating or supplying gaseous mixing current:

This subclass is indented under subclass 650. Apparatus comprising a device which develops a gas flow or acts as a source of supply of gas, to mix with the material.

(1) Note. The current of gas may be applied to the material after it has been introduced into the ambient, may mingle with the material in the strewing means before it reaches the ambient, or may act as a fluid to entrain and transport the material to the ambient.

(2) Note. If the current of gas is applied to the material in the ambient, this is considered to be the strewing means required for this definition (see subclass 650); otherwise the strewing means must meet the requirement set out in (2) Note of subclass 650 in regard to either the rotary or nozzle type scatterer.

(3) Note. Included under this definition is a device comprising a single gas stream developing or source means discharging to a plurality of strewing means.

655	.. Laterally extending scatter unit:

This subclass is indented under subclass 654. Apparatus comprising an elongated strewing means extending in the direction of its length outwardly from the supply holder when looked at in plain view the longitudinal axis of the elongated strewing means being substantially transverse to the direction of any intended movement of the supply holder.

(1) Note. For meaning of "elongated strewing means" under this definition see (1) Note in subclass 664.

656	. Scatterer fed by plural containers:

This subclass is indented under subclass 650. Apparatus in which a single strewing means is supplied with material from a plurality of supply holders.

(1) Note. The supply holders must be primary containers of the material such that different materials may be supplied. A mere dividing wall in the lower portion of a container is not included, such apparatus being classified on other features.

(2) Note. Included under this definition is any arrangement of two primary holders, connected in such manner that a mixture of the two materials can be supplied to the single strewing means.

657	. Container tilted for discharge (e.g., dump truck, etc.):

This subclass is indented under subclass 650. Apparatus in which the supply holder is mounted on a support means so as to be movable from a first position in which the material in the holder is not readily movable out of the holder by gravity to a second position in which gravity causes or greatly assists in the movement of the material out of the holder.

(1) Note. The support means must comprise more than a wheel axle about which the supply holder may be tilted by the user of the device. Such devices are classified on other features.

(2) Note. This subclass is the locus for patents comprising tilting containers of the dump truck type, even if details of the dump mechanism are not recited.

658	. Scattering means is flail:

This subclass is indented under subclass 650. Apparatus in which the means for strewing comprises a flexible element which is rotatable about an axis and is so constructed or arranged that it assumes a substantially vertical or drooping position when at rest and a position substantially at right angles to the axis when rotated to strew the material.

(1) Note. For the means of "rotates about an axis" see (1) Note in subclass 681.

(2) Note. Included as a flexible element under this definition is an element pivotally connected to a rotary carrier.

(3) Note. The means may be positioned within the container to scatter the material therein, or may be without the the container, the material being supplied thereto.

SEE OR SEARCH CLASS:

172,	Earth Working, subclass 45 for an implement of the flail type for working or disturbing the earth.

659	. Scattering means has to and fro movement (e.g., vibratory, etc.):

This subclass is indented under subclass 650. Apparatus in which the strewing means has an oscillating, reciprocating, shaking or other back and forth movement while in operation in order to effect or assist the strewing function.

(1) Note. The movement of the strewing means may be caused either by a positive drive or by the impingement of the material onto such means so as to cause the back and forth movement due to the construction or arrangement of the means, e.g., the means is of springy material which vibrates when hit by the material.

(2) Note. The main structural difference between this subclass (659) and the vibratory subclasses of Class 222, Dispensing, subclasses 161, 196-203 is that in subclass 659 the vibrating member is sufficiently near the terminal material contact point that the vibratory movement causes the discharging material to scatter, while in Class 222 the vibration merely causes the material to move toward or out of the discharge outlet.

SEE OR SEARCH THIS CLASS, SUBCLASS:

102.1+,	for a device which sprays a fluid by means of a motor driven element which cyclically and rapidly changes the normal character of discharge of fluid from an outlet (e.g., by continuously moving the discharge member, or continuously moving a member in contact with the fluid).
225.1+,	for a fluid spraying or sprinkling device comprising a distributor which is continuously moving (e.g., oscillating) relative to a support during discharge.
652,	for a device in which a nonfluid material is caused to be scattered or strewn by reciprocation of a tube manually by a person.

660	. With overload release or relief:

This subclass is indented under subclass 650. Apparatus in which a part of the apparatus shifts its position relative to an adjacent part without the intervention of a human operator, and in response to a transient condition in which a part of the apparatus would be subjected to undesirable stress (e.g., when a lump, clod or rock is encountered in otherwise easily disintegratable material) if shifting did not occur.

(1) Note. Shifting of position which occurs in order to take up the shock of starting is not included under this definition. Such devices are classified on other features.

661	. With means for mounting on tractor:

This subclass is indented under subclass 650. Apparatus comprising a means disclosed for attaching the apparatus to a motor vehicle of the type which does not have any substantial provision for supporting material for transportation but is especially intended to pull a trailing vehicle or to pull or support an implement, such as a plow, which operates to perform its intended function while being so pulled or supported.

(1) Note. The motor vehicle of this definition is usually called a tractor.

(2) Note. Apparatus under the definition is typically constructed to be used as a detachable unitary attachment for a tractor.

662	. With feature relating to liquid material:

This subclass is indented under subclass 650. Apparatus in which there is a means (e.g., a leak proof supply holder) which is especially provided because the material contains liquid which tends to or does separate from the solid portions of the material.

(1) Note. The material as a whole under this definition is not a slurry, i.e., a mixture of solid particles and a liquid which is handled as a viscous liquid. Apparatus for handling a slurry is classifiable as if the slurry were a liquid. Typically, the material being handled by the apparatus of this subclass is manure, some portion of which is liquid.

663	. Convertible or combined:

This subclass is indented under subclass 650. Apparatus not provided for in preceding subclasses and which (1) is in combination with features other than for material handling or treating or (2) by relative rearrangement of its parts or by the addition or omission of a part is so changed as to become (A) basic subject matter of the same class of a different character or having a different mode of operation or (B) basic subject matter of another class.

(1) Note. A mere preamble in a claim to the effect that a device is convertible or is a conversion attachment is generally not sufficient for classification under this definition. The conversion feature should be spelled out as by (a) specifically claiming one embodiment of an apparatus having a first function and claiming with that embodiment a feature useable only for a different function, or (b) repeated functional statements in the claim, or (c) a preamble which is so long and detailed that it may be considered part of the body of the claim. Where no other suitable classification exists a broad mention of conversion may be enough for classification under this definition.

(2) Note. The change in the apparatus must be more than merely placing a part in one of a series of adjacent holes, or making a change which amounts to only an adjustment, changing between operative and inoperative positions or other minor alteration in the overall functioning of the device.

(3) Note. Examples of devices included under this definition of "combined" are combinations with (1) a separator to classify or assort different portions of the material, (2) a plurality of different types of discharge members (e.g., a material discharge guide for Class 222, Dispensing and a strewing means for this class, etc.) with means, as a valve to selectively and alternatively choose the type of discharge depending on the material handled, (3) brake means acting on vehicle wheels, (4) vehicle features in addition to those required for the handling of the material, etc. Included under this definition of convertible is an unloading or dispensing vehicle of the type classified in Class 414, Material or Article Handling, Class 298, Land Vehicles: Dumping, or Class 222, Dispensing and a strewing or scattering means of the type classified in this group of subclasses and attachable or removable at will. Excluded from "combined" under this definition is the combination with any type of physical treatment of the material (e.g., comminuting, heating, agitating, etc.) or handling, (e.g., loading, conveying, etc.).

664	. Ambulant container and laterally extending scatterer:

This subclass is indented under subclass 650. Apparatus which is intended to be used by traversing a surface, comprising an elongated strewing means extending in the direction of its length outwardly from the supply holder when looked at in plain view, the longitudinal axis of the elongated strewing means being substantially transverse to the direction of intended movement of the supply holder.

(1) Note. The "elongated strewing means" under this definition comprises any arrangement of strewing means which (1) results in a pattern of strewn material which is generally elongated when the whole apparatus is not traversing the surface, the pattern extending in the direction of its length outwardly from the supply container and laterally of the direction of traverse of the apparatus over the surface and (2) is physically located outwardly from the container in a direction laterally of the direction of traverse of the apparatus over the surface.

(2) Note. Excluded under this definition of "elongated strewing means" is a single rotating scatter located outwardly of one side of the container, or two rotating scatterers, one on each side of the container and extending outwardly therefrom in a direction laterally to the direction of traverse; such devices will be found in 681+. However, a plurality of rotating scattering units arranged side by side transverse to the direction of movement of the container and located outwardly of the container is included under this definition.

This subclass is indented under subclass 650. Apparatus comprising a strewing means rotating about an axis and means for changing some characteristic of the pattern of the material being strewed, such as its direction or width.

(1) Note. For the meaning of "rotating about an axis" see (1) Note in the definitions of subclass 681.

(2) Note. A means for changing a characteristic comprising no more than a means for changing the speed of the strewing means, a means for changing the amount of material fed to the strewing means or a means for changing the speed or direction of a vehicle on which the strewing means is mounted is not included. Such devices are classified on other features.

This subclass is indented under subclass 665. Apparatus comprising a selectively adjustable member which intercepts the path of at least some of the material after it leaves the strewing means, the adjustment of the member effecting some change in the pattern of the material being strewed.

(1) Note. For purposes of this subclass definition, a rotating "feeder" which inherently acts as a scatterer, but which, as disclosed, delivers material to an adjustable deflecting or strewing element, is considered to be the "strewing means".

Apparatus in which the supply holder has an opening in a lower portion thereof and is so constructed, with at least one sloping wall leading to the opening, that the material is discharged by the action of gravity, and in which the strewing means rotates about an axis and receives the material in a direction substantially transverse to the axis.

(1) Note. For the meaning of "rotates about an axis" see (1) Note in subclass 681.

(2) Note. An agitating or disintegrating means may be used to assist the flow of material by breaking up lumps, but the supply holder must be so constructed that the use of a conveyor or ejector to move material horizontally is not necessary.

671	. Including raking type conveyor moving material toward scatterer:

This subclass is indented under subclass 650. Apparatus comprising a means acting in substantially a linear direction on the top portion of the material in the supply holder to force or deliver the material towards the strewing means, in the manner of a rake.

(1) Note. A rotating means, e.g., a "beater", acting on the top of the material is not included in this definition. See subclass 680 for a beater acting on the top portion of the material.

672	. Including driven conveyor or follower feeding material horizontally towards scatterer:

This subclass is indented under subclass 650. Apparatus comprising means acting on the material in the supply holder for delivering it in a horizontal direction toward the strew-means, said delivering means comprising (1) a driven conveyor or (2) a means acting as an end of the material in the supply holder.

(1) Note. If a series of strewing means is claimed, (e.g., a rotating "beater" throwing material to a rotating "widespread") a strewing means upstream of the final means is considered to be a kind of conveyor. If, however, such a series of strewing means is shown, but the final one is not claimed then an upstream strewing means, e.g., a beater, which, as claimed, functions like a final strewing means, is considered to be a final strewing means for purposes of placement under the definition of subclass 650.

This subclass is indented under subclass 672. Apparatus comprising at least two strewing means, each of which rotates about an axis to perform its strewing function and each of which is disclosed as strewing material into final position in the ambient, rather than to another downstream strewing means, the material being presented to each of the strewing means in a direction which is substantially parallel to the axis of rotation and being scattered in substantially a radial direction.

(1) Note. For the meaning of "rotates about an axis" see (1) Note in subclass 681.

(2) Note. Just what constitutes a plurality of strewing units rather than a single unit with a plurality of parts is sometimes difficult to decide. If one unit rotates on a different axis than another, or in a direction opposite to that of another, a plurality of units is considered to exist. However, sometimes where there are distinct sub-assemblies, each comprising a complete unit, a plurality of units are considered to exist even if they rotate about the same axis.

674	.. Feed means outside of primary supply container :

This subclass is indented under subclass 672. Apparatus in which the means for delivering material toward the strewing means is located outside of the confines of the principal supply holder for the material.

676	.. Including movable gate, barrier or valve upstream of scatterer:

	This subclass is indented under subclass 672. Apparatus comprising a movable means acting on the material before reaching the strewing means, which functions as a valve to regulate flow of material to the strewing means or in one position prevents the material from pressing against the strewing means and in another position permits the material to reach the strewing means.

677	.. Speed varying means for driven scatterer or feed:

This subclass is indented under subclass 672. Apparatus comprising a driven strewing means and means for varying the rate of movement of the strewing means, or of the means delivering material towards the strewing means, independently of the speed of the primary driving means for the strewing or delivering means.

(1) Note. The speed varying means must be capable of changing speed at the will of the operator while the apparatus is in motion; merely replacing one gear with another while the apparatus is at rest is not included. A means which stops the motion of the conveyor or other feeding means at a predetermined position is excluded and will be found in subclass 678, even if the conveyor or other feeding means is reversed in direction and its speed in this reverse direction increased.

678	.. Limit means stopping feed:

	This subclass is indented under subclass 672. Apparatus comprising means which causes the motion of the material delivering means to be interrupted when the delivering means arrives at a pre-selected position, without the intervention of a human operator.
