IPC: G07B1/02
Abstract: 690,681. Totalizators. UNION TOTALISATOR CO., Ltd., and HANDLEY, J. Jan. 21, 1949 [Jan. 21, 1948], No. 1905/48. Class 106 (i). An installation which specifies the odds values on the tickets as they are sold, and totals the amounts to be paid on all tickets for each competitor on an adding machine allotted to each competitor, totals all the cash taken and all competitors on another adding machine, and varies the odds on the competitors throughout the selling period or restricts the sale of tickets on a particular competitor. To control the odds on the various competitors, post office type selector banks with switching wipers are employed. Controlling units driven through differential gears, one side of which is driven by the movements of the odds adding machines which total the pay-out value of the tickets, and the other side of which is driven in the opposite direction by the pool total adding machine which adds all the cash taken by sale of tickets, are used to operate the odds control switches. So long as the tickets sold on any competitor have a pay-out value equal to the total of cash taken on all competitors, the gears on each side of the differential carrying the switching wipers will rotate in opposite directions at the same speed and the controlling unit will remain stationary. As soon as a competitor pay-out total commences to exceed the pool total, the wipers are advanced to the next row of contacts and mark out a lower ratio of odds for that competitor, so that the totals come into balance again. If a competitor payout total falls below the pool total, the wipers are retarded and mark out a higher ratio of odds so that the totals of sales and commitments will again come into balance. The percentage for overheads may be controlled by the ratios of the gear drives from the pool total counter, so that if 16 per cent is to be deducted, the common differential shaft would be rotated by an 84-toothed gear driving a 100-toothed gear. The selector switch banks control the odds price printing of the ticket issuing machines, and the stake selectors for the competitor adding machines. To reduce the number of wires used to control the.odds being printed in the ticket machines, where six competitors are provided for, six groups of five wires commoned to all ticket-issuing machines, terminate on five wipers of the odds selector banks, and each group of five wires provides control for up to 32 values, through being marked in different combinations of code. When a competitor key on a ticket issuing machine is depressed (say competitor 3) the type-wheel is rotated to print competitor 3. At the same time No. 3 key, either directly or by operating a relay, gives this machine access to competitor 3 odds price lines, so that the odds price wheel in the machine may rotate to print the price marked on the five wires, from the controlling selector banks. A selector switch is used to drive round the odds type wheel, the marked earth holding the switch when it has taken the correct position, and has brought the relevant odds price type face into printing position. Adding machines similar to the type described in Specification 592,946 are employed. All the ticket-issuing machines are controlled from the same odds price lines, the different values being printed by the type, i.e. if a two-shilling ticket issuing machine is printing an odds price of four shillings and ninepence at a particular time for competitor 3 a ten-shilling ticket-issuing machine will print ú1 3s. 9d., or alternatively may print the number of 2/- units at 4/9 per unit. The regulation of the odds control switches may come under the control of the supervisor, and the control unit used only as an indicator. A locking-point may be provided on a cash difference indicator to hold up acceptance of bets, if necessary. Alternatively the supervisor may change the odds and either cancel all ticket-issuing machines waiting to send a bet or prevent further machines from setting up on a particular competitor. Operation. A race number key is thrown which puts positive on to the wire corresponding to race No. 1. Ticket-issuing machine operators then turn the race control switch 3, Fig. 1, until the marked wire is found, at which point relay RN3 has its resistance 3a shorted out so that it restores and opens contact rnl which releases the solenoid S to unlock the machine. Contacts rn2 and rn3, Fig. 1, close and the totalisator is ready to accept bets. Then, for example, a 2/- bet on competitor No. 1 is made with the odds control switch OS, Fig. 15, set at 7 to 8 or 3/9. The stake control 4 is set by its handle to the 2/- position so that wipers 6 and 7 rest on their first contacts 61, 7<SP>1</SP>. The competitor selector 1 is then rotated until its wipers 8, 9, 10 and 11 engage outlets 81, 91, 101 and 11<SP>1</SP>, at which point plunger 12, Fig. 13, trips the lockplate 14 and releases the bolt 15 to lock the outer selector wheel of the ticket-issuing machine. Contacts mx<SP>1</SP> of the odds finder are closed, driving magnet OFDM1 to step the wipers round until OF1 has found the earthed contact, i.e. the 6th contact in this case. Contacts mx2 have energized the printing handle lock PL to prevent operation of the machine. Next the dial 18 of the odds selector 2 is rotated by key 19, Fig. 11, until the wipers 20 find the earthed contact, when the odds locking magnet OL7 is energized via the printing handle contacts ph1. Closing of contacts oll provides a circuit via the winding of relay OP6, contacts r4 and mx7 and isolating key TK to bank SX1 of the motor-driven switch. The wipers are arrested by operation of Smx when they arrive at the correct contact. Contacts op4 operate the single bet relay of the multi-bet counter via wiper 7 and contacts mx4. Contacts op5 operate the relays RLA5, RLB4 of the odds counting machine, Fig. 7, via wiper 6 and contact 6<SP>1</SP> of the stake selector 4, wiper 9 and contact 9<SP>1</SP> of the competitor selector 1, and contacts nrl2 of the non-runner relay NRL3 in the odds adding machine. Contacts op6 operate and cancel lock CL1. The bet is now registered and the release signal sent back to operate a relay which in turn locks up r3 and ph3. Contacts r1 release the printing handle lock PL. Contacts r2 continue to hold CL1, whilst r4 releases relay op6 and r5 lights a lamp to indicate that a ticket may be printed. The printing handle PH is then operated to print and issue a ticket, releasing OL7 and CL1 at ph1 and ph2 when the handle is pulled forward, and releasing r3 and ph3 when it has fully returned, and issued the ticket. To enable the money registered as odds on the odds adding machine to be compared with the money registered as stakes on the total stakes adding machine, an impulsing cam LP on the stakes adding machine, Fig. 5, sends an impulse to the magnet on each of the odds adding machines for each ú1 or ten 2/- units received by the total stakes adding machine. Specifications 434,273, 441,063, [Group XXXVIII], 455,133, 455,134 and 572,103, [Group XXXVIII], are referred to.
