to be typed on the ticket.
Components of the system illustrated in Fig. 6, which correspond with those in Fig. I, are given like reference numbers. In the modification of Fig. 6 the various stages of selection of an individual storage unit are to be performed in the same manner as has been described with reference to Fig. 1. However, the entire selecting mechanism comprising different finder switch stages is shown collectively in the block 71 of Fig. 6.
The output circuits from-the final stage of selection switches are referenced 27 in Fig. 1. They are therefore given the same reference numeral 21 in Fig. 6 and show individual conductors to each of the responsive relays 29 in the individual storage units such as 58..
From the foregoing description of the modification shown in Fig. 6 it will be seen that either the signal for "rejection" or the signal for "allotment" is transmitted for selective actuation of one or the other of the solenoids 53, 52, depending upon whether or not the wiper 66 rests on segment 65 when the storage unit selecting relay 29 is operated. The motor magnet 67 does not operate if all available allotments have been exhausted. Therefore the "allot"-solenoid 52 will not operate when it is necessary to transmit the "rejection" signal for operation of solenoid 53, and vice versa. Furthermore, repeated Inquiries for allotments after they have been exhausted will all produce the reject signal, since the wiper 66 must remain standing on segment 65 until a reset signal is transmitted, or until a cancellation is to be registered.
When it is desired to reset the rotary switch for any individual storage unit, various well-known means may be employed. For example, a reset key 59 on the teleprinter may be made-to close contacts for impressing ground potential on the conductor 70 leading through contacts b of relay 29 and thence to the motor magnet 67. Thus, after response of relay 29 to the usual selecting signals, a single operation of key 59 operates to pulse the motor magnet 67 once for stepping the wiper G6 back onto the first of the interconnected segments 64. Further steps of the wiper 66 may then be taken by repeated operation of relay 29, the same as for making allotments, but in this case to obtain a starting registration of the full allotment quota, or for correcting the registration so as to give effect to a cancellation.
In the foregoing description of Fig. 6 it should be understood that I do not claim as my invention any of the individual components of rotary switches or teleprinter apparatus, but have simply described this modification as one wherein such components may be put together in a novel manner for accomplishing the inventive objects of my invention.
The keys 41 and 41d were described above as being useful for adjusting each storage unit to a certain capacity and for releasing balls one by one to take care of cancellations. Cancellations may also be taken care of by remote control and automatically as recorded on the teletype machine. Fig. 5 shows how thus may be done.
Two rods 13 and 74 extend through holes in the wall of each storage unit respectively, and in place of the keys 41 and 41 ca. These rods are pivotally attached to the ends of a toggle lever 15 and are actuated reciprocally by means of a linkage member 79, connected to a lever-arm 18 which is an extension-piece with respect to the armature 77 of a magnet 76. The magnet, when energized by a pulse which may be initiated by key-operation of the teletype machine, operates against the tension of a spring 80. The armature heel rests against a back-stop 81 when not attracted. Each magnet core is mounted on an iron heel-piece 82 and all of the latter are supported along a horizontal elbow-bar 83. When the armature 77 is pulled up, then rod 73 is withdrawn sufficiently to release a ball 40 so as to drop down the space of one ball diameter and is there momentarily arrested by the interjected rod 74. When the magnet 76 releases,, then the action of the rods 73 and 74 is reversed. The released ball drops out of the storage unit and the ball next above it (if any) is retained in place by the interjection of rod 13 beneath it.
According to techniques which are well known in the telephone switching art the use of the finder switches as hereinabove described may be extended so that if a special key is actuated on the teletype machine immediately preceding the typing of the final digit of the storage unit identification number, then the selection of a desired one of the magnets 16 would occur in place of selecting a magnet 29 for the same storage unit. Thus, a notice of cancellation may be registered on the teletype machine and taken care of by the storage unit affected, this operation being facilitated automatically just as well as in registering reservations that are to be made.
Other modifications may also be made without departing from the spirit and scope of the invention, as-will be appreciated by those skilled in the art.
