Patent GB-289901-A (GB)
Abstract: 289,901. Tannen, R., and Wallace, R. Nov. 2, 1926. Totalizators.-Electric key board-operated ticket issuing and registering apparatus is provided wherein the actuation of the ticket-issuing mechanism is brought about solely as a consequence of a movement of the registering device, to ensure that a ticket is not issued unless the registering device is actuated. The ticketissuing machine has two sets of keys 22, 23 for " Win " and " Place " bets respectively a crowding-lock being provided to prevent the depression of more than one key at once. Each key actuates a switch 30 to actuate a corresponding counter and indirectly to close the circuit of a motor 40 of the ticket issuing mechanism, and the key remains depressed by the engagement of a plate 92 with teeth 91. The motor 40 drives a shaft 43 through reduction gearing, means being provided to ensure that the shaft turns through one complete revolution when a key is depressed. A gear 45 on the shaft 43 drives a pinion 47 having a frictional connection with a shaft 48 on which is mounted a printing drum 52 whose sides correspond to the number of horses for which the machine is arranged. The drum is rotated until one of a number of radial projections 53 is stopped by an abutment 39 carried by the key lever, each prujection being wide enough to engage the stops of two adjacent keys 22, 23. A second printing roller 68 with flanges 82 for feeding a paper strip 56 is driven by a gear 65 meshing with a gear 46 on the shaft 43. The gear 45 carries a lever 61, one end of which engages a fixed guide plate 63, and the other engages a spoke of the gear 46 when it is forced in by the guide plate. By this means, the gear 46 rotates only during a third of the rotation of the shaft 43, after printing by the roller 52 has been effected. Associated with the roller 68 are printing- wheels 72, 73 and these are slidable relatively to the roller under the control of the keys to print " Win " or " Place " on the strip. Each key-lever engages one of the inclined faces 80, 81 of a strip 79 connected to the rollers 72, 73 to select the printing. Inking rollers 107 are provided, and printing is effected by a block 57 actuated by a cam 58 and by a roller 67, while a knife 103 actuated by levers 101 and cams 100 severs a ticket from the strip. In order to ensure that the shaft 43 does not make more than one revolution, a plate 121 lying on the key-levers and secured to a spindle 120 is engaged when a key is depressed to rock the spindle and to remove a plunger from the path of a cam 114 carried by the shaft. This allows the shaft to rotate, but when the key is released the plunger is lowered and engages a radial face of the cam to stop the shaft. Release is effected by a bar 88 on a spindle 87 engaging a lever 89 to release the plate 92. The bar also actuates a counter 95 for the number of tickets issued. The counting and indicating apparatus is operated by the closing of the switches 30, each switch energizing a solenoid 180, there being one solenoid for each indicating device. Associated with each solenoid is a constantly rotating disc 168, in which is pivoted a pin 169 carrying at its end a plate 173 and a ramp 171. When an armature 181 is shot out, it presses against the disc, and rides up the ramp 171, thereby causing itself to tilt about a pivot 181 to close contacts 185, and projecting the plate 173 outwards so that it engages a pin 156 on the units drum 154 of the indicator. A projection 178 engages an ear 177 on the plate 173 to restore it, and a pin 175 limits the movement of the plate. The contacts 185 complete the circuit of the motor 40, and the indicating apparatus must thus be operated before a ticket can be issued. The higher order indicators are provided with notches into one of which a spring arm on the units indicator is swept by a cam at each revolution. A spring member 161 engages recesses in the indicators to hold them set. Before the contacts 185 open, a contact strip 125 on the shaft 43 closes the circuit of the motor 40 to keep the motor running until the shaft has made a complete revolution. The discs 168 are mounted on a shaft 162 driven by a motor 164, and the shaft 162 drives a shaft 204 operating a total indicator. Each unit indicator 154 actuates a plate 187, connected by links 189, 192 and a lever 190 to a lever 193, to operate a shutter 195, thereby releasing a ball 198 from a shoot 197 for each unit to be made. The balls accumulate in a shoot 202 and fall one by one into pockets 206 in a disc 203 on the shaft 204. As the balls are carried round, they pass into the teeth of a wheel 208, rotating the wheel and driving the units drum 217 of the total indicator. The balls are removed from the pockets by a deflector 212, and run down a shoot 214 to the shoots 197. Where several ticket-issuing machines are employed, each disc 168 has associated with it a corresponding number of solenoids and plates 173.
