Abstract: 718,717. Ticket-issuing machines. BELL PUNCH CO.. Ltd. Sept. 10, 1951 [Oct. 11, 1950], No. 21315/51. Classes 106 (1) and 106 (3). [Also in Group XVI] A ticket-issuing machine comprises a pair of printing devices each adapted to be set to a plurality of different printing positions, key operated means for selectively setting one of said printing devices, second key operated means for selectively setting the other of said printing devices, means for effecting printing of a single ticket by both of said devices and separate means controlled by said keys for registering the number of tickets printed by each combination of positions of the said two printing devices. The invention is applied to a ticket issuing machine for use in a totalizator system for issuing one ticket to correspond to a so-cal'ed " double " bet. The main drive comprises a motor 2, Fig. 4, which drives a pinion 8, Fig. 5, through gears 4 and 6. The pinion 8 drives a shaft 11 through a clutch comprising a mutilated gear 10 on the shaft 11 and a gear segment 16 carried by a lever 14 pivoted to the gear 10. During a machine cycle the teeth of the gear 10 and the segment 16 are in continuity but normally the segment 16 is he'd in retracted position by a lever 24. A main shaft 32 is driven from the shaft 11 through gearing. Ticket feeding, printing and issuing.-The ticket strip S, Fig. 6, is fed from a container 45, Fig. 8, between a pivoted cover 48, Fig. 6, and a guide 47, by a pin wheel 44 on a shaft 42 rotated by the shaft 11 through a Geneva mechanism comprising driving and driven elements 34. 40 respectively. A switch 590, Fig 8, is actuated when the last ticket of the supply leaves an arm 592 to give .a signal of the exhaustion of the strip. The platen 52, Fig. 6, is removably secured by screws 54 to a support 57 carried by a slide 50. A cam 64 on the shaft 32 co-operates with a pair of rollers 62 on the slide 50 to effect upward movement thereof. The printing head includes code printing type 66 of a replaceable slug 68, replaceable date and machine symbol printing type 70 of a slug 73 and numeral printing wheels 74, 76, settable as described later. The printed ticket is cut by a guillotine comprising a fixed blade 78 and a blade 80 reciprocated by a pivoted lever 86 the forked arms 92, 94 of which co-operate with a roller 96 on the Geneva drive disc 34. The roller 96 also rocks pivoted lever 100 the upper end of which engages an abutment on the slide 50 which is thereby retracted after printing. The printed ticket moves over a plate member 106 on to a table 107 against which it is held by a pivoted lever 108 controlled through linkage from a cam 126 on the shaft 32, Fig. 8. A pivoted finger 130 bears by gravity against the uppermost ticket. The carbon paper C, Fig. 6, is fed intermittent'y from a roll R, Fig. 10 (not shown), between the printing head and the ticket strip S by a feeding roller 148, Fig. 8, and a serrated ro'ler 158. Keyboard.-The machine has two banks of keys 164, 188, Fig. 4, corresponding to the first and second races. Each key 164 has a stem 166 and is connected by a pin and slot to a member 174 similarly connected to a lever 184 pivoted on a rod 186. Each key 188 has a stem 190 connected by a pin and slot to a member 198 similarly connected to a lever 208 pivoted on a rod 210. Each pair of members 174, 198 are interconnected by a spring 214. A key 164, 188 corresponding to a scratched runner may be disconnected from its associated member 174, 198 and locked. Crowding locks comprising rocking members 226 are situated between the levers 184 to prevent depression of more than one key 164. A similar series of pivoted elements 246 co-operate with the levers 208. A plate 228 carried by a shaft 230 underlies the levers 184 and is connected by a pin and slot to one arm of a bell-crank 240, Fig. 3, the other arm of which lies adjacent the elements 246 so that depression of a key 188 can only be effected after depression of a key 164 has rocked the bell crank 240 clockwise. The forward end of the bell crank 240 is connected to the stem 244 of a reset key 245 so that a key 164 depressed in error may be immediately returned. Locking and unlocking of machine.-The stem 244 of the key 245 is normally prevented from upward movement by the engagement of a pin 248, Figs. 2 and 3, thereon with a pivoted lever 274 connected by linkage, 266, 264, Fig. 2, 260, 258, Fig. 3, to the plungers 254, 256 of two solenoids 250, 252. When the solenoid 252 is normally energized the lever 274, Fig. 2, frees the key stem 244. If the solenoid 250 is energized, however, the stem 244 is blocked by the lever 274 and the machine is thereby locked. A plate 286 mounted on a shaft 288, Figs. 3, 4 and 5, underlies the lever 208. An arm 292, Fig. 5, carried by the shaft 230 is connected to an arm 289 carried by the shaft 288 through the linkage 296, 300, 298. A roller 304 on the gear 28 rocks the lever 300 clockwise to rotate the shafts 230, 288 clockwise and return the depressed keys. Record taking.-At the front of the machine in thirteen columns and rows are one hundred and sixty-nine printing counters, one counter for each combination of two keys one in each row, one counter for each key and one total counter. These counters are shown at 508, Fig. 4, and each is mechanically actuated by a link 488 through the known mechanism shown in Fig. 11. A transfer device of the deep-notch type is provided in each counter. The links 488, Fig. 4, extend through slots in members 492, Fig. 9, urged upwardly by springs 496 and supported by a frame 454, Figs. 4 and 9. Each member 492 corresponds to a key 188 and has at its top a slot. 498 through which passes one end of a lever 500 carried by a shaft 418. Each lever 500 is connected by a link 502 to the corresponding. lever 208. The thirteenth member 492 is connected to a lever 551, Fig. :3. Each lever 184, Fig. 4; is connected by a link 476 to an arm 478 carried by a shaft 480 supported in the frame 454. Each of the twelve shafts=480 carries a plate 482 and a thirteenth plate 484 is adjustably fixed to the frame 454. The frame 454 is connected at its four corners to bell cranks 456, 458, 460, 462 the lower pair being joined by a shaft 469 and each connected to the corresponding upper one by a vertical link 464, 466. The bell crank 460 is connected by a link 470 to an eccentric strap 472 embracing an eccentric on the shaft 32. The one hundred and sixty-nine hammers 555, Fig. 4, which print on record sheets 724, 728, Fig. 20, from the printing counters 508 are enclosed in a frame 540 which may be moved outwardly and are attached to angle members 548 on horizontal shafts 546 each of which has an arm 558, Fig. 2, pivoted to a common link 560 spring urged upwardy. A link 564 pivoted to the link 5'60 is connected to one end of a pivoted lever 566 having a roller 570 which follows a cam 572 rotated through gearing from a normally enclosed hand crank 580. The hammers are thus moved with snap action when the crank 580 is rotated. Setting of printing wheels.-Each of the levers 184, 208 is provided with a hook 346, 352, Fig 4, respectively which lies adjacent a corresponding projection 342 and' 348 spaced' and' offset around shafts 338, 340 respectively. Pinions 339, 341, Fig. 3, at the ends of the shafts 33'8, 340 mesh with gear segments 354, 356 carried respectively by arms 358. 360 spring urged counterclockwise about. a common pivot 361 and carrying rollers 366 which follow cams 370, 372 on the shaft 32. Ratchets 374, 376, Fig. 2, on the shafts 338, 34'0 arenormally engaged by spring pressed detents 378, 380 controlled by a cam 3'90 on the shaft 32. The shafts 338, 340 are drivingly connected to the printing; wheels 74, 76, Fig. 6, through bevel' gears 392, 396 and 394, 398 respectively. Star wheels 400; 402 secured to' the printing wheels 74, 76 co-operate with a pivoted aligning lever 404, Fig. 5. connected through an arm 406, a spring 408 and a rod 410 to a pivoted lever 412, which co-operates with a roller 416 on a disc 320 on the shaft 32. Operations.-The solenoid 252 is energized so that the machine is unlocked as described above. A selected key 164 is depressed to rock the associated lever 184 and position its nose 346, Fig. 4, in the path of the correspending lug 342 on the shaft 338. The plate 228 moves and the lever 300, Fig. 5, is rocked. The lever 240, Fig. 3, is rocked clockwise to allow depression of a key 188. The movement of the lever 184 is transmitted to the corresponding plate 482, Fig. 4, through the link 476. A selected key 188 is now depressed and latched by the plate 212. The corresponding, lever 208 is thereby rocked to bring its nose 352 into the path of the corresponding. lug 348 on the shaft 340 and the corresponding s'ide 492 is raised to lift all the associated links 488 so tnat one link 488 and one plate 482 are in alignment. The plate 286, Fig. 5, is rocked and this movement is transmitted to the lever 310 the end 312 of which frees the lever 24 to the action of the spring 20 and a pin 322 thereon closes. The switch 324, Fig. 4, to start the motor. At the same time the gear segment 16, Fig. 5, is rocked to engage the pinion 8. The shafts 11, 32 are given a counter-clockwise and a clockwise rotation respectively. The detents 378, 380, Fig. 2, are released, and during the rotation of the shaft 32 the gear segments 354, 356, Fig. 3, are released to effect rotation of the shafts 338, 340 for amounts depending on which member 184, 208 has been moved. The printing whee's 74, 76. are thereby set. Roller 416, Fig. 5, then engages the lever 412 to actuate the aligning detent 404. The cam 64, Fig. 6, then raises the platen to effect printing of a ticket. Roller 96 then engages the arm 94 of the lever 86 to retract the blade 80 which, is then held in its retracted position by a spring 82. The cam 126 on the shaft 32. Fig, 8, then. lifts the clamping member 108 to
