Abstract: 6797. Haddan, R., [National Cash Register Co.]. March 17. Tickets, issuing and cutting-off; printing-arrangements.-O n e or m o r e tickets according to the value of the coin inserted are printed and severed and delivered from a continuous strip, and a counting mechanism, which indicates the total value of the coins inserted and tickets issued, is simultaneously actuated. The operating-mechanism may be driven by hand or by a motor, for example of the type described in Specification 17,534/08. Separate slots are provided for coins of different values and a separate operating-key is provided adjacent each coin slot. The insertion of a correct coin frees the corresponding key, the depression of which by the purchaser serves to effect (1) the closure of the coin insertion slots ; (2) the locking of the depressed key ; (3) the differential setting of the rack for actuating the counting-mechanism, and of the controlling-means for determining the number of revolutions of the main shaft of the operating - mechanism, c a c h revolution effecting the delivery of a p r i n t e d ticket; (4) the withdrawal of a locking-mechanism from the operating-mechanism. As the tickets are delivered, the controlling and locking mechanisms are returned step by step to the normal position. The apparatus is shown as adapted to receive a five, ten, or twenty-five cent piece, and to deliver one, two, or five tickets, there being three operating-keys 1, 2, 3, Fig. 2, and a coin slot adjacent each key. The key-locking mechanism operates as follows. When a key is depressed, a pin 37<a> projecting from it enters the corresponding sloping slot 65 in a plate 19 supported at its lower end by an arm 21 pivoted to the framework, and moves the plate down against the action of a spring 23, thereby rocking a lever 49 from engagement with the arm 51 of a bell-crank lever 52 which is connected by a pin 58 with a rod 59 ; thereupon a spring 64 pulls down the rod 59 to lock the key, the corresponding projection 62 on the rod snapping over a projection 6 on the key. Simultaneously the bell-crank 52 moves a roller 57 on a pitman 55 into engagement with a cam 65<a> on the main driving-shaft 56. During the first revolution of this shaft, the rod 59 is returned to the unlocking position, whereupon the spring 23 restores the plate 19 and a spring 64<a> raises the key. The controlling-means for the operating-mechanism comprises a toothed sector 48 with locking-pawl 166, and a co-operating ratchet 47 with locking-pawl 165, the sector and ratchet being mounted fast on a spindle 46 to which is also secured a locking-arm 91 and (if a motor be employed) a second locking- arm 92, Fig. 10. The pawl 166 is differentially set by the depression of the corresponding key to permit the rack to be moved back by a spring 164 through the space of one, two, or five teeth, the ratchet 47 and locking-arms 91, 92 accompanying the rack, and the pawl 165 being removed from engagement with the ratchet by a pin 180 on the bell-crank 52 during the keylocking operation (described above). The setting of the pawl 166 is effected from a spindle 134 through links 173, 169, the spindle 134 being adapted to be rotated through different angles by the depression of the different keys, pins 126 on the keys rocking levers 128 connected wtih the spindle through separate linkages. The locking- arm 91 being thus withdrawn from engagement with a notched disk 161 on the main shaft, this shaft can be rotated by means of a crank-handle (or a motor), and during each revolution the sector 48 is returned one tooth by a pawl 182 which drives the ratchet 47. This pawl is pivoted to a pitman 179 controlled by a cam 1800, and co-operates with a cam disk 186. To permit the step-by-step return of the sector, the link 169 is disengaged from the pawl 166 by a lever 174, Fig. 3, operated from a cam 178, the link 169 being returned to the normal position during the actuation of the counting-mechanism (described below). In Fig. 10 the main shaft 56 is shown driven from an electric motor through a clutch 88, 89 as described in the above-mentioned Specification, the clutch automatically coming into action when the locking-arm 92 is withdrawn simultaneously with the locking-arm 91. The circuit of the electric motor is simultaneously closed by an arm 104 controlled by notched disks on the spindle 56 described in the above-mentioned Specification. The ticket-strip passes from a storage roller between rollers 188, 189, Fig. 5, and over a platen 203 ; the platen is rocked from a cam groove 208 on the face of the roller 189 to press the strip against a fixed type block 206 and print the value of the ticket. The strip is then fed forward by projecting ribs on the roller 188, the number and date being impressed on the ticket by mechanism of known type carried by this roller. Finally, the printed ticket is severed by a movable blade 210, which co-operates with a fixed blade 213 and is carried by a slide 211 operated from the cam-groove 208. The rollers 188, 189 are driven from the shaft 73. Registering, value of.-An actuating-rack 125 is differentially set by the rotation of the spindle 134 (described above). The counting-train is carried by a pivoted frame 141, which is rocked to bring the wheel of lowest order into engagement with the sector by a pitman 145 co-operating with a cam on a shaft 73 geared to the main shaft 56. During the first revolution of the shaft 56, the rack 125 is returned to the normal position and simultaneously actuates the counter by means of a pitman 149 connected to the link 169 and operated by a cam on the shaft 73. The counting-train is of the type described in Specification 24,452/96.
