430,539. Ticket-issuing machines. ELLER, F., 23, Waltharistrasse, Wannsee, Berlin. May 16, 1934, No. 14766. Convention date, May 16, 1933. [Class 106 (iii)] In machines for cutting-off, printing, and issuing strip tickets in which the ticket is fed between a cylindrical drum with adjustable printing blocks and a cylindrical platen, the printing blocks are mounted in radial guides and are moved into the cylindrical printing surface as required by operating members engaging key-controlled stops as the drum rotates. In the railway ticket printing machine shown in Figs. 1, 2 and 3, the strip 1 is led between rollers 3, 4, through the knife 5, between the printing drum 6 and platen 7, between the date printing rollers 22, 22a and out through the opening 80<1>. The printing drum 6 carries for example, five radially adjustable printing blocks 6<a>, 6b, 6<c>, 6d, 6e, each operated by the appropriate key 12 to bring it outwardly into the printing circle. Depression of any one of the keys switches in the motor 27 which turns the printing drum 6 and platen 7 through one revolution. The key also turns one of the levers 10 mounted side by side on the shaft 16 until its hooked lower end projects into the path of one of the sectors, for instance the sector 8<c>, associated with the corresponding printing block 6<c> as shown in dotted lines. This is effected through the links 11 and levers 14. As the drum rotates, the hook catches the edge of the sector 8<c>, thereby causing it to rotate, together with its cam 53, so that the printing block 6<c> may be moved outwards by springs 52. A spring-controlled lever 15 holds each lever 10 in or out. The lever 10 is ultimately returned as the drum rotates by a roller 21 which engages a heel 19 on the lever. The printing block is also returned by a fixed cam 71 which engages a roller 70 at one end of the sector. The depression of any one of the keys also, through levers 38, 36, 39, closes the switch 40 of the motor 27, which, through worm gearing 28, 29 and ratchet mechanism 31, 26, imparts one rotation to the platen 7 which is geared to the printing drum 6. The engagement and disengagement of the ratchet gearing is controlled by a lever 34 which is released by lever 36 when the switch is closed so that its long arm drops and is raised a little later by a roller 41 engaging the platen. Towards the end of the cycle, roller 32 on ratchet arm 31 engages the curved surface of lever 34 and disengages the ratchet gear. Fingers 57<a> on the platen engage the printed ticket and move it between the dating rollers 22, 22<a> and out through the slot 80<1>. The back of the ticket may be printed with invariable matter by a block on the platen 7. Each of the printing blocks carries a toothed sector 43, which, when moved outwardly with the block, operates its appropriate counting mechanism 59 through a pinion 56 and bevel gear.
