Patent GB-393000-A (GB)
Abstract: 393,000. Totalizators. BLACK, H. D., The Island, Uxbridge, and DEGEN, A. A. C., Peveril, Headstone Gardens, Harrow, both in Middlesex. Dec. 24, 1931, No. 35750. [Class 106 (i).] Machines for issuing tickets of different values, one value to each machine, and connected with corresponding common price lines, are assigned by a rotary switch and when the ticket is of a multi-unit value a control means in the central equipment ensures successive unitary registrations to the required number before allowing the machine to be uncoupled and assignment to proceed. The drawing shows two ticket machines A, B allocated respectively to 2s. bets and 10s. bets and provided with a contact T1 connected with the corresponding one of a number of price lines 1, 2, 3. Key contacts AK..HK select the horse number, and the nature of the bet (win or place) is determined by closure of a contact WK or PK. A distributing switch at the central station has the contacts of its banks RS1, RS2, RS3 connected respectively with the contacts T1, T2, T3 of a relay T in each machine while the fourth bank RS4 is in circuit with the machine starting-magnet SM. Registering single-unit bets. Depressing a horse number key closes a contact AK and also a common contact CB thus energizing relay T to close the contacts T1, T2, T3. Relay H operates over contact T1 and by its contact. H1 holds the distributer operating magnet DM energized and thus maintains the switch RS stationary. Relays AW, AP are energized over T3, the horse contact AK and line a, and contacts AW1, AP1 complete a holding circuit for relay H, other contacts AW2, AP2 prepare a holding circuit and contacts AW4, AP4 prepare a circuit for the horse-counting magnets AWC, APC. A further relay TW is also energized over contacts T2, WK (if for a win) and line W, and contact TW4 consequently completes the circuit for magnet AWC through AW3, Q1, TW4, AW4. Simultaneously the grand total counting-magnet TWC is operated over AW3, Ql, TW4. Both counting-magnet armatures are thus advanced and a guard relay GY is also energized over contacts GX2, Q2, AWR1, AW5, TW3. Contact GY3 now completes the holding circuit for relay AW and guard relay GYT is energized over AW3, TW5, Q4, GXT2 to complete at GYT3 a locking circuit for TW. The two guard relays thus being energized, contacts GY4, GYT4 in series complete the circuit of the ticket machine starting- magnet SM and a relay R. As contact R1 now counting-magnets permitting their armatures to restore and so effect the count. The contacts AWR1, TWR1 mechanically operated by these armatures now open and the guard relays GY, GYT consequently relapse and at GY3, GYT3 release the relays AW, TW and therefore relays Q, H, whereupon the switch RS advances to the next machine. The guard relays are duplicated at GX, GXT and interlocked with the others, the pairs of relays being brought into use alternately through the oppositelyactuated contacts such as AWR1, AWR2 and TWR1, TWR2 to prevent interference in the registration of bets on different horses. As a further precaution the guard relay circuits include contacts controlled by relay Q. breaks the circuit of relay T, the ticket machine is disconnected from banks RS1, RS2, RS3 of the distributing switch, but the relays AW, TW, H remain locked up. Movement of the armatures of counting-magnets AWC, TWC closes at AWC1, TWC1 a circuit from GYT4, GY4 to relay Q which then locks up at Q1 through contact AW3, and brings down the Registering multi-unit bets. When a bet of 10s. is entered on machine B, the primary relays above referred to are held locked until the counters have been operated five times to register the five units. With the machine set and connected up by the distributing switch a relay TT is energized over line 2 and locks up at TT2, X1. A contact TT21 completes circuit for relay H, a contact TT1 for magnet DM and a contact TT22 for a relay M. The registering operation proceeds otherwise as before but the locking circuit of relays AW, TW is now controlled by relay M at M1. Each time the guard relays operate, their contacts (GX3, GXT3 or GY3, GYT3) cause relay Z to energize and at Z2 maintain circuit to relay Q. Relay HT is also energized through Z1, Z3, TT2 and closes HT1 to energize the driving magnet DMT of the rotary switch RLT. As soon as the counting-relays AWC, TWC are released by relay Q, relay Z relapses so that HT, DMT are de-energized and the switch RLT advances one step. Relay Q is also de-energized at HT2 and consequently the counting-relays AWC, TWC are again energized and held and another unit added to the counters. This process continues until the switch RLT arrives at the fifth contact when it prepares the circuit of a relay X to be energized by relay Z at Z11 and lock up at X2. Relay M is now prepared for release by contact X1 and relay Q is held energized by X3. When the fifth unit has been registered and relay Z relapses, relays M, TT are released by Z1, and H by TT21, so that switch RS may advance to the next machine. A relay N controls the earth connection to the banks of the switch until all the bet units have been registered and contacts M2, H2 consequently opened. A similar collection of switch RLL and relays HL, LL serve for registration of 10 unit bets entered in machines wired to line 3. According to the Provisional Specification the various price control switches RLT, RLL may be combined into a single switch. Specification 390,183 is referred to.
