Abstract: 743,478. Ticket-issuing machines. BELL PUNCH CO., Ltd. (General Register Corporation). Nov. 20, 1951, No. 27257/51. Class 106 (3). [Also in Group XVIII] Printing tickets: setting type wheel.-A printing device is driven to select the characters to be printed on a ticket delivered by a coin-freed machine until it is arrested by a selector means which has been operated manually. The invention is illustrated as applied to the machine of Specification 743,479, [Group XVIII], in which a button 315, Fig. 19, is depressed to select the destination legend to be printed on the ticket. The printing wheel 1025, Fig. 54, carrying the destination legends is turned through not more than 180 degrees, in a direction dependent on which selector button is depressed, by a chain 295 and is indexed by engagement of a slider 293 or 294 (according to the direction of motion) on the chain with a portion 305, Fig. 19, of the depressed button. The chain 295 is driven by a sprocket 805, Fig. 54, from a bevel gear 785, Fig. 49, through either of two bevelled pinions 789, 790 selectively clutched to the shaft 788 of the sprocket 805 by a dog 795 which is slid along the shaft by a lever 800 and link 960 when a rocker 955 is turned about its pivot 953. The rocker is turned to reverse the transmission to the printing wheel when the upmost of two pins 956 or 957 which it carries is engaged by a projection 386a or 390a at the lower end of a link 386 or 390 depressed by a crank 385 or 387 on a shaft which carries a bail such as 378, Fig. 19, engageable by projections 307 on half the selector buttons stems. The bevel gear is driven from an oscillated shaft 547, Fig. 50, through gears 779, 780 and a spring 815 which yields when the printing wheel is indexed. The printing wheel is further indexed by a disc 1044, Fig. 54, teeth 1046 on which are engaged by a roller 1050 on a lever 1047 urged about its pivot 1048 by a spring 1052 secured to a sliding bar 1053 depressed during printing by a cam 1069 on a shaft 1000 directly coupled to the motor shaft 757. A dating pad set by knobs 1207 ... 1210 is disposed adjacent to printing wheel 1025 and, as the ticket to be delivered is being printed, a code designation is printed on the next ticket by a small adjustable wheel. The ticket strip is pressed against the printing wheel by a leather surface 1274, Fig. 55, on a pad 1160 which is oscillated by a reciprocating link (not shown) engaging rollers 1256 on either side of the pad to push them from one side of a spring- biased cam 1240 biasing the pad to the other. At the limit of the movement of the pad a pin 1278 on it engages under a flange 1162 on a mast 1161 to raise this from engagement with the printing wheel. Feeding ticket strip.-The ticket strip 1135, Fig. 55, is fed through a length slightly greater than a ticket by intermittently rotated knurled rollers 1100, 1101, one of which is mutilated, and is then correctly indexed by a pin wheel 1110. The spindle 1137 of the roller 1101 carries a gear meshing with the gear on the spindle of the roller 1100 and carried by a lever 1148 biased about its pivot 1150 by a spring 1153. The spindle 1088, Fig. 74, of the roller carries a pinion 1084, by which it is driven from a mutilated gear 1082, and a cam 1096 which turns a spring-biased lever 1140 about its pivot 1144, Fig. 57, to retract a roller 1142 from a notched disc 1102 which indexes the pin wheel. A curved channel section guide 1118, Fig. 55, retaining the ticket strip on the pin wheel is retracted by a spring 1120 when a toggle catch 1130 is released. Cutting tickets from strip.-A moving blade 1194, Fig. 54, is pivoted to a fixed blade 1193 and supported by springs from the upper member 1178 of a frame 1180 guided to slide vertically on columns 1167, 1171. The frame 1180 is normally held in the raised position shown by a lever 1070 engaging a roller 1183 on the member 1178 and held against movement about its pivot 1071 by a roller 1077, Fig. 74, on a lever 1076 pivoted at 1076a. When a cam 1080 having a pin and slot connection with the shaft 1000 releases the lever 1076, springs 1191, 1192, Fig. 54, pull the frame 1180 down on to buffers 1184, 1176 so that the blade shears the ticket strip. Feeding carbon strip.-The take-up reel 1330, Fig. 83, for the carbon strip is driven through a ratchet wheel 1337 by a spring-biased pawl 1344 the stroke of which is reduced as the diameter of the used carbon strip increases. The pawl 1344 is carried by a lever 1340 oscillated about its pivot 1341 each time a ticket is delivered by a link 1350 pivoted at 1349 to a link 1346 pivoted at 1356, Fig. 74 and 54, to the lever 1070 controlling the ticketcutting blade. The link 1350 carries a pin 1345 which engages a slot 1342 in the lever 1340 at a radius determined by a roller 1355 on the link 1350 engaging the roll of used strip.
