Abstract: 307,551. Bethell, G. M. Dec. 14, 1927. Totalizators.-In an electric totalizator provided with means for registering win and place bets, separate manually operated switches are provided for controlling the circuits to the win and place groups of indicators and to the separate horse indicators. Issuing-machine controls. The horse-selecting lever 106. Fig. 2, is pivotally carried by an arm 119 fixed to a hollow shaft 107 and cooperates by a pin with a circular series of locating holes 108. The type of bet is determined by adjustment of a lever 110 connected with a vertically movable masking plate 154 to expose an indicator corresponding with the setting. The race number to be printed is set by a knob 112, Fig. 8, and a testing switch 111 is also provided. Horse selector switch. A disc 127 carried by the hollow shaft 107 supports a number of spring bridging contacts 97, 98 to connect conducting rings 93, 94 with selected contact pins 95, 96 the rings and pins being mounted in a stationary plate 129. As shown in Fig. 10 the inner and outer rings of pins are in circuit respectively with " win " and " place " horse counters 101, 102 while the rings are connected through the class of bet switch 159 with the operating switches of the machine. Class of bet switch. The rocking of the finger lever 110 raises or lowers a bar 150, Fig. 2, adapted to rock a switch arm 159, Fig. 10, to bridge pairs of contacts 77, 79 and 81, 85 or 78, 80 and 82, 84 and thus prepare circuits through the grand counter 73 or 74 and the horse counters 101 or 102. The bar 150 also controls a slidable sleeve to bring eccentrics upon it into operative relation with one or other of two class counters 192, 193, Fig. 8, so that one of these and also a total counter 189 are stepped when the machine operates. The bar 150 also sets a type carrier 167, Fig. 2, to characterize the ticket as for a win or place. The bar is locked during the operation of the machine by means of a bolt connected with the magneticallyoperated clutch shunted with the motor, and correct positioning is essential owing to a bridging contact 175<1>, Fig. 10, capable of allowing current to pass to the motor only when spanning contacts 176 and 175 or 177. Printing arrangements. The ticket strip passes between a hinged plate 286, Fig. 2, and a spacing drum 282 provided with feed pins 283 and driven by a gearing connection with a star wheel 251, Fig. 5, rotated through two teeth at each cycle by a. two-toothed segment 250 fast on a shaft 240 worm-geared with the motor. The strip then passes between feed rollers 255, 256 also driven from the segment and between a platen 272 and a series of type carriers viz., a roller 198 geared with the race number knob 112, an electro plate for printing the date and fixed matter, the " class " carrier 167 already referred to and finally a horse number type wheel 124 rigid with the setting shaft 107. The platen is reciprocated towards and from the type by eccentrics on the main shaft 240, a resilient buffer plate being interposed. The platen also carries a knife to sever partially the ticket strip. Indicator and motor circuits, control of. The indicator circuits are shown in thick lines in Fig. 10, which gives diagrammatically the circuits from and to one ticket-issuing machine coupled up with others by means of the usual distributor 89 such as that described in Specification 233,702. The class switch arm 159 having been set as above described, say for a win bet, and the testing switch arm 298 being in the " recording " position shown, the actuation of the distant counters 73 and 101 takes place when the setting handle 106 is plunged to connect the ring 93 with one of the contacts 95. The impulse thus given is momentary and is immediately followed by closure of the motor circuit which persists for a complete cycle of operation. The means whereby these results are, accomplished are as follows. The setting handle 106 is engaged by a spring-controlled rod 117, Fig. 2, slidable within the shaft 107. When the handle is plunged the rod rocks a lever 211 into the position shown in Fig. 2, where it is latched by one arm of a spring-controlled four-armed lever 213 - - 216, Fig. 5, thus locking the handle down. The latter lever has prior to this been held inoperative by the lever 211 but in the new position the arm 216 bridges contacts 219, 220. On the spindle 217 is fixed a trigger arm 223 and connected with it by a spring is a contact arm normally bridging contacts 226, 227. Thus with both pairs of contacts bridged, circuit to the indicator is completed. The registering impulse passes through a solenoid 234 which consequently rocks a lever 229 to bridge contacts 230, 231 and at the same time unlatch the trigger arm 223 and a second similar arm 222 loose on the spindle. By closure of the contacts 230, 231 the motor circuit is complete and by the unlatching of trigger arm 223 the contact arm can rise and thus break the registering circuit at 226, 227. The motor now operates and towards the end of the cycle a cam 235 on shaft 186, rocks the four-armed lever to release and be held by the locking lever 211 and to open the main circuit further at 219, 220. Another cam permits the loose trigger arm 222 to rise and block the lever 229 thus maintaining the motor circuit until the end of the cycle when the cam again depresses the trigger arm to allow the lever 229 to break the motor circuit and to relatch the trigger arms. Another cam operates the trigger arm 223 to reset it and then leave it free to ascend when unlatched in the next operation. Manual unlocking of horse selector. When the handle 107 is plunged in a position corresponding with no runner the, rod 117 becomes locked down by the latching of lever 211 as above described but as the unwanted horse circuits are out of action no operation of the machine occurs. To release the handle therefore a lever 279, Fig. 8, must be shifted to rock the four-armed lever to inoperative position again and to free the lever 211. Testing. In addition to the testing switch 298, Fig. 10, operated by the knob 112 to throw in the motor circuit, two contacts 131, 132 are provided at the nought position on the selector switch. When the handle is moved to this position and plunged therefore the motor is operated but the impulse passes through a resistance circuit 312 instead of through the counters.
