Abstract: 193,032. Haddan, A. J. H., (National Cash Register Co.). Oct. 6, 1921. Tickets, issuing; printing - arrangements; registering value of.-A machine for printing and issuing theatre &c. tickets of several classes or values is adapted to receive interchangeable printing and totalizing elements, whereby any section of the machine may be prepared to issue tickets of any determined value, corresponding with the printing element inserted in that section. The machine is operated by hand or motor, under the control of keys, one for each section, as described in Specification 193,356. Prior to the insertion of a printing element the actuating mechanism of the section concerned is set manually in correspondence with the value to be printed by the element, and the insertion of the element locks the setting mechanism. Upon the depression of a key and operation of the machine a strip ticket, Fig. 13, is printed and issued from a section, and the value is registered on the totalizer carried by the inserted element. A removable element carrying only a grand totalizer is inserted at one end of the machine, and its actuating means are coupled to those of the section then functioning, as described in Specification 193,356. The ticket strips, which may have different colours, are fed through shoots 305, Figs. 1<A> and 1<B>, by rollers 306, 307 adapted to print on the back of the tickets fixed matter such as the name of the theatre &c. and pass between the detachable elements supported in frames 505, and platens 337. The strips then pass through slots in a plate traversed by knives 342, the severed portions being delivered through shoots 345 by rollers 343, 344. Printing and registering elements, construction of. Each element comprises hand-set date-printing members 432, Fig. 15, plates 431 bearing price type, consecutive number printing-wheels 441, and numeral-wheels 481 constituting the value totalizer. The units wheel of the numbering device is driven by a ratchet wheel 448 engaged by a pawl 444 carried by a plate 443 loose on a shaft 442, the plate 443 having a pin 455 engaging a lever 457 adapted to be engaged and rocked by a pawl 462, Fig. 1<B>, on a lever 463. The numeral-wheels 481 of the totalizer are rigidly connected with pinions 483, which in the case of the three lower order wheels engage with three transmitting pinions 469, Fig. 1<B>, when the whole element is moved forward during the operaton of the machine. The pinions are normally locked against actuation by detent members 488 engaged by a yoke member 492 having a projecting finger 498. This finger is engaged automatically to release the detents as the element is moved forward during operation of the machine. Setting, differential and transfer mechanisms. Before a printing element is inserted in the machine, arcuate members 153, Fig. 1<A>, are adjusted manually to limit the throw of actuating segments 161, which are adapted to drive the pinions 469 through wheels 571, the setting being indicated by numbers viewed through an aperture 156. When the insertible element is in position in the machine the setting members are locked, as described later. The units actuating pinion 469 is rotatably mounted on a stud on a plate 574 rigidly supported on a shaft 575 and rod 576, while the tens and hundreds pinions are mounted on plates 577 capable of a rocking movement about the shaft 575 so as to impart a planetary motion to these pinions for effecting transfer. The transfer teeth 582, Fig. 6, for the higher orders are carried by plates 581 capable of a similar but more extended rocking movement. Associated with each numeral wheel of the totalizer is a disc having a single tooth which at transfer engages a pawl 584, and rocks a member 583 to bring a spring pawl 587 thereon into the path of a cam 588 on the shaft 575. After sufficient time has elapsed for actuation to take place the shaft 575 is rocked from the main shaft and rocks the transfer member 583. A roller 585 on this member thereupon wipes past a retaining pawl 586 and through a cam slot 593 imparts a planetary movement to the pinion 469 or produces displacement of the teeth 582 to effect transfer. The transfer parts are restored by a cross rod 611, carried by arms on a shaft 556 rocked by a link 615, Fig. 2B, from the main shaft 52. Mounting of elements and locking of setting means. A shaft 458 extending through the sides of the printing element engages in slots 508, Fig. 1<B>, in plates suspended from a frame 500, attached to a lid 503 having lugs pinned to a shaft 404 forming a pivot, so that by retracting a lock bolt 551 all the elements may be raised and exposed for inspection or exchange. The grand totalizer element is supported by a separate frame 561, Fig. 2B having lugs loose on the shaft 404. Mounted on a shaft 513 in the frame 500 are spring latching arms 512 engaging in front of the projections 498 of the yokes 492, Fig. 15, and having tail portions 521. When the lid is raised, the shaft 513 may be rocked manually by means of a knurled segment 516, to release the elements for removal, but when the lid is closed the engagement of the tail portion 521 with a fixed plate 381 renders the segment 516 inoperable. A shaft 553 at the front of the hinged frame 500 carries notched arms 555 engaging a shaft 556 under the action of a spring 557, and has an arm 552 blocked by the bolt 551 of the lock. After unlocking the lid a. knurled segment 563 is free for operation to disengage the arms 555. The lid and parts carried thereby are lifted, when the locking bolt 551 is released, by means of a spring connected to a link attached to an arm on the shaft 404. The other end of the link is connected to an arm on a rock shaft 103, which is thus moved when the lid is opened to release a cam 544, Fig. 1<A>, from engagement with members 542 normally locking the setting members 153. The shaft 458 of each element is received in forked arms 524, Fig. 1<B>, on a shaft 355 adapted to be rocked by a cam on the main shaft 52 at the beginning of an operation to move the elements forward into engagement with the pinions 469. Operation of machine; cutting off and issuing. The printing rollers 306 are driven by elliptical gearing 317, 316, Fig. 1B, from the main shaft 52, to effect rapid printing. The platen 337 for each section is pivoted to arms 353 on shaft 355 and is moved by a toggle system 361, 362 operated by a cam on the main shaft, to take an impression just after the beginning of an operation. The lever 463 is rocked to engage the pawl 462 with the consecutive numbering device when a key is depressed, and remains engaged until released automatically by the depression of a key of another section. The movable knife 342 of each section is mounted on spring arms 384 reciprocated by arms 386 mounted on a shaft 387. This shaft is rocked by a cam and link connection from the main shaft at the end of an operation. The delivery rollers 343 are mounted on the shaft 404, while the rollers 344 are mounted on a shaft 405 carried by arms 406, Fig. 2<B>, on shaft 387. A pinion on the shaft 405 is driven by interrupted gear driven from the main shaft 52 by elliptical gearing.
