Patent GB-297048-A (GB)
Abstract: 297,048. Julius, G. A. June 13, 1927. Totalizators.-The selection of the horse and of the kind of bet (place or win) is performed by rotational movement and radial adjustment respectively of a setting-lever which may then be depressed to close circuits for operation of the ticket-issuing mechanism and the central counters or indicators. The setting-lever 30, Fig. 2, is slidably mounted in the hollow stem 54 of a T-head having a depending bearing socket 28 rigidly carrying a gear sector 56, for setting the horse number type-wheel 58, and a bracket 24 supporting a switch arm 21 ranging over an arcuate series of " place " contacts 18 and a similar upper bank of " win " contacts 17. The setting-lever is shown in Fig. 2 as positioned for registering a place bet but if slid to the left a link 60 rocks a bell-crank 62 to lower a rod 45 and thus through a lever 26 raise the arm 21 into engagement with the upper contacts 17. The movements of the rod 45 are also conveyed through a lever 42 to a type sector 48 for printing " place " or " win " on the ticket, and shaft 33 throws a switch arm 32, Fig. 11, from One to the other of two contacts 34, 35 to close circuit to the " place " or " win " grand and horse counters. The plunging motion of the setting- lever depresses a tube 65, Fig..2, to rock a shaft 70, Fig. 12, having a fast arm 71 normally supporting a spring-controlled arm 72. Removal of the arm 71 permits the arm 72 and shaft 73 to rock clockwise to close circuit at 80 to a solenoid 83, Fig. 4, the core of which has a roller 85 to free a latch 88 from an arm 90 rigid with a spring-controlled stop 93 normally blocking a projection 95 on the driven clutch member 96. The clutch is thus released for rotation and when one rotation of the driven shaft 109 is nearly terminated a roller 112 depresses the arm 90 to re-latched condition and replaces the stop 93 in the path of the projection 95. Another roller 135, Fig. 5, on the solenoid core lowers an arm 133 to free a lug 132 thereon from the heel of a floating lever 121 supported from a shaft 124 by an arm 123 and carrying a pair of contacts 137, 139. Normally the contact 137 engages contact 138 but the action of the solenoid frees the lug 132 from the lever 121 so that spring 130 can rock the latter to open contacts 137, 138 and close contacts 139, 140 which complete the circuit to the magnetic clutch to commence the drive. Near the end of the cycle a cam 115 on the main shaft 109 breaks the motor circuit at 118 and another cam 108 allows the shaft 124 to return and carry the contact lever 121 back to normal position where it is again latched by arm 133. The co-operation of the latch parts 71, 72 prevents the return of the selecting-lever after plunging, until the shaft 73 is rocked in the operation of the machine. The release of the lever may also be effected by manual depression of the key 77, Fig. 12. Fig. 3 shows the arrangement of the printing-mechanism, the voucher strip 190 entering at 191, being printed with fixed characters by rollers 193, 196 and receiving the imprint denoting the horse, type of bet, and number of race by the descent of a platen 52. The voucher is severed by a guillotine 198 and ejected by mechanism 199. An ink-ribbon 254 adapted to be reversely wound and the operation of producing a ticket are the same as in the machine described in Specification 144,650. To put the machine entirely out of action a key 148, Fig. 14, can be depressed to displace a plunger 176 and break the circuit. The plunger can be restored only from below and by an authorized person. The circuits are shown in Fig. 10 wherein in addition to the selecting-lever and the switches controlled by it there may be seen (1) a bank of cut-outs 114 whereby only those contacts 17, 18 pertaining to the horses competing can be rendered live; (2) the " place " grand and horse counters R, L and corresponding " win " counters K. M; (3) commutators 169, 182 and their holding switches 168 for enabling seven issuing machines to be grouped for simultaneous working; (4) a condenser 189 for preventing sparking and (5) a distribution switchboard 166 and fuses 153. In order to test the efficiency of the machine a switch 161 is thrown over and the selecting-lever moved to and plunged at hole 188. This results in the production of a ticket bearing the word Test " and no registration on the counters takes place. To prevent withdrawal of a partially printed ticket, sharp toothed wheels mounted in levers 217, Fig. 3, are lightly pressed by springs 218 against the ticket in its proper forward movement, but upon withdrawal are caused by tension to deface the ticket. A pair of local counters 40, 41, Fig. 11, for totalling the place and win numbers are actuated by springs 308, Fig. 13, drawing down slotted links 206 when allowed by the downward rocking of arm 306 fast on a shaft 305, which is rocked by arms 304, Fig. 15, links 303 and a lever 211 loose on a shaft 300 carrying a fast arm 302 with a pin 301 bearing on the lever 211 which is pressed against it by the spring 308. The shaft 300 is rocked by a connecting rod 310, Fig. 3, from a printing shaft. Both counters 40, 41, are disabled when a " test " ticket is issued by a lever 210 which is swung into the path of the lever 211 by an arm 212 rotatable with the selector lever 30. The rocking of the shaft 33 by the radial setting of the selector lever 30 throws over a stop arm 39, Figs. 2, 3, and 11 to engage a pin 400 on the link 206 operating that counter which is not appropriate.
