Abstract: 166,458. Shanklin, B. M. Aug. 13, 1919. Ticket punches.-Strip-ticket punching, issuing, and severing machines, of the kind in which the ticket is punched to indicate date, time of day, and destination, are provided with a number of groups of punches and selecting means for each group which are carried by a member moved to operate the punches after the selection has been effected. The date-selecting devices can only be adjusted by a responsible person on removing part of the apparatus, but the remainder are set by the operator, the destination punches being controlled by a set of depressible keys. Main and auxiliary strip-feeding mechanisms are provided, together with severing means. The punch casing a, Fig. 1, is carried by a pillar b mounted so as to be portable on a base c, a foot lever 15 controlled by a dash-pot v being carried thereby. Series of punches 21 - - 26, Fig. 11, are mounted in a removable plate 18 and represent respectively the month, day of the month, the hour., quarter of the hour, A.M., or P.M., and the destination. The various selector devices by which the punches are operated are carried by a depressible spring- supported frame p, Fig. 3, guide-rods 29 of which move on brackets 29a and are connected by a plate 31. Members 35, 36 for operating the punches 21, 22 are carried by a plate 32 which is mounted below a plate t forming part of the frame p and must be removed before adjustment can be effected. Selector members for the punches 23 are carried by a shaft 39 and comprise radially and spirally arranged members 40, the shaft being rotated on the depression of a key 47, Fig. 2, through a bell-crank lever 45 and a pawl 44 engaging a ratchet wheel 42 on the shaft 39. Numbers showing the hour of the day are carried on the edge of a disc 41 secured to the shaft 39 and a spring stop is provided to position the disc. The selector members for the quarter-hour, A.M., and P.M. punches 24, 25 are carried by a shaft 52 rotated in a manner similar to that of the shaft 39 and comprise pins 61 radially and spirally arranged as shown in Fig. 6, and two semicircular members 63 adapted to engage one or other of the punches 25. Selection of the destination punches is effected by the depression of spring- retracted rows of keys 66 which, when lowered, rock bell-crank levers 65, Fig. 8, into position to engage the punches 26 when the frame p is lowered. Each row of keys is provided with a spring-controlled locking-plate 71 adapted to engage a shoulder carried by a projection 69 and so connected that the depression of a second key in any row frees that first depressed. Operation of the punch-carrying frame is effected on the depression of the foot lever 15 through a rod 79, Fig. 3, carrying a lever 80, upward movement of which rocks through an arm 82 a shaft 83. A toothed sector 90 on the shaft 83 rocks, through a loose pinion 91 bearing a pawl engaging a twotoothed ratchet wheel 95, a shaft 92, a cam 93 on which depresses the selector-carrying frame p. The ticket-strip is fed from a reel on a shaft 17 through a slot i<1> below the punches by main feedrolls 96, 97 and supplementary feeding devices, comprising pawls on levers engaging perforations between the tickets, which act when the main device is rendered inoperative. The severing- means comprises a knife 127, Fig. 3, carried by pivoted arms 128 and operated by a sector 139 on the shaft 83 through toggle links 132, 133, 131.
