Patent GB-280207-A (GB)
Abstract: 280,207. Siemens & Halske Akt.-Ges. Nov. 2, 1926, [Convention date]. Tickets, issuing.-A ticket-printing and issuing machine is released for operation and also controlled as to number of operations by a single manipulation. As shown in Fig. 1, a ratchet member 11 determining the number of tickets issued is set by means of a sector 6 having apertures 2 - - 5 and turned in the direction of the arrow 7 by placing a finger in the desired aperture and drawing it forward to the full extent, an arm 9 on the sector 6 engaging a projection 10 on the member 11 and a pawl 13, Fig. 4, preventing return of the member. With the operation of the sector 6, a lever 1 is rocked to bring the end of a push-rod 15 into engagement with an arm 17 of a lever 35. and so withdraw an arm 18 from a tooth 19 carried by a pawl 20. A spring 21 thereupon forces a nose 22 of the pawl 20 against a disc 23 fixed on the main operating shaft 29 and finally into a recess 31 in the disc, thereby clutching in a cam disc 33 carrying the pawl. The cam in its rotation then engages a roller 34 on the lever 35 so that a part 37 of this lever pushes the rod 15 aside to disable the lever 1. With the movement of the member 11, a pin 12 allows a lever 25 to move anticlockwise until a face 27 meets a square projection 28 of the lever 35, and finally, on rotation of this latter lever, a recess 36 on the lever 25 engages the projection to lock the lever. The cam 33 is connected to a gear wheel 40 driving a printing roller 42 which bears adjustable type cylinders 43, 44 and a toothed quadrant on the printing roller engages a gear on a platen roller 144 to feed tickets intermittently. A knife 46 connected to a lever 52 rocked by a cam 50 severs a ticket while the strip is stationary. As the lever 52 rocks, it releases the pawl 13 from the ratchet 11 and allows a second pawl 14 to engage the teeth, so that the ratchet 11 moves step by step with the issue of the tickets until the pin 12 operates the lever 25, thereby releasing the lever 35 to disengage the pawl 20. A cam 49 operates a trip lever 57 to release the lever 52 at each revolution. Each ticket passing through a slot 45 is pressed by a slide 69 past spring- mounted projections 70, 71 and is held between these projections and a spring-pressed plate 72, so that the tickets are collected in the form of a bundle. The slot 45 may be covered by a hinged plate to prevent the insertion of coins &c., the ticket pushing the plate away against the action of a light spring. To disable the setting and machine release means during operations the arm 9 is pivoted at 62 to the sector 6 and passes through the head of a pin 64 mounted in the hollow pivot 63 of the sector. A rod 65 having an inclined face 64 is connected to the lever 35 and is pulled down when the lever moves, so that the face 66 drives the pin 64 against a spring 68 and removes the lower end of the arm 9 from the path of the projection 10. Electric contacts may be arranged to close the circuit of a driving motor each time the machine is operated instead of employing a continuously-running motor, and a crank-handle may be added for manual operation of the machine. Additional machines may be employed for printing and issuing a constant number of tickets at each release, a conveyer being employed to forward the tickets to the issuing point. A feeler for the paper strip may operate means to uncouple the drive and to lock the release mechanism if the strip should fail. According to the Specification as published under Sect. 91 (3) (a) the selection of the number of tickets to be issued may be effected by keys, the stems of which act differentially upon the sector 11. This subject-matter does not appear in the Specification as accepted.
