402,131. Totalizators. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 64, Heathwood Gardens, Charlton, both in London. May 26, 1932, No. 14969. [Class 106 (i).] In a totalizator having a number of counters adapted to register bets laid on particular contingencies, means are provided for combining signals appropriate to a bet on a " double " contingency and for directing the signals to an appropriate counter. Figs. 1, 2 and 3 show a ticket issuing machine in which competitor keys KC1, KC2 and stake-value keys KSV1, KSV2 are provided. The ticket issuing machines are successively associated with the transmission circuits by an assignor Fig. 4, and any particular " doubles " bet set up in a machine by the depression of corresponding keys in the competitors' groups KC1, KC2 effects the selection of relays Fig. 9, which close a circuit corresponding to the particular " doubles " bet for effecting selection of a corresponding counter Fig. 17. The selection of the counter and operation thereof in accordance with the value of the stake is controlled by a relay set Figs. 10-14 assigned by an assignor, Fig. 19. In addition to the individual counters, a grand total counter, Fig. 18, is provided. The apparatus also is adapted for " all combinations " betting, i.e. backing all possible combinations of competitors in two races and for " forecast pool " betting wherein bets are laid on two competitors in the same race occupying particular finishing positions. Registration of " double bets." The groups of relays 1DF-6DF, 1DS-6DS are allocated to the competitors of different races, and are operated by a control officer by keys (not shown) in such a manner that only those relays corresponding to the competitors in each race are energized. To register a " double " bet, keys, in the groups KC1, KC2, are operated corresponding to the competitors in the two events together with key contacts in the groups KSV1, KSV2 appropriate to the stake value. The keys also operate key strip contacts CPC1, CPC2, CPS to operate relay M, the relay UL, Fig. 3, being energized over " event " switches RNS, RN. Relay M operates STT, Fig. 4, which operates relay S, Fig. 2, over wiper AST1 of the assignor, Fig. 4, assuming the latter is in position (1). Relay S closes the circuits of the operated keys to effect operation of appropriate relays in the competitors' groups CAF-OFF, CAS-CFS, Fig. 9, and a group of relays, such as 1SU, 5SU, Fig. 16, two only of which are shown, corresponding to the stake value. The selected relays close appropriate contacts in the groups caf1, cbf1-, cas3, cbs3- 1su2, 1su3-, Figs. 9 and 16 to effect selection of a counter relay e.g. CU, Fig. 4, corresponding to the " double " bet and facilitate operation of the counter in accordance with the value of the stake. The selected relays in the competitors' relay groups, also operate relay C, Fig. 10, over contacts such as cbs1, caf3. Relay C operates relay TSA, Fig. 19, which completes the counter selecting circuit through the contacts of the competitor and stake relays over wiper ASC4 of the control set assignor. A second circuit is closed over the wiper ASC2 and the appropriate stake contact in group 5su1-5su1 for a relay in the grand total counter, Fig. 18. The individual and total counters are then operated in known manner in accordance with the value of the stake. Further operation depends on the completion of the counting operation upon which relays RC, RG (not shown) pull up contacts rc1, rg1, Fig. 17, 18, to close a circuit for relay R over wiper ASC5 in series with driving magnet ASCD and relay ASA. When both counters have completed their operations, this circuit is opened and the assignor is stepped. Operation of ASCD and ASA brings about operation of relay RT, Fig. 3, which energizes relay IT, Fig. 4, over wiper AST1 and chain contacts rt2, m1 &c., Fig. 3, and de-energizes S to remove battery from the key circuits and de-energize C which together with relay IT operates ASTD, RA in series. Magnet ASTD opens circuit of IT at contacts ast, the relay releasing to de-energize ASTD and step the assignor. Relay RT also controls the setting into operation of the printing and issuing machine. When in the course of issuing a ticket a certain stage is reached contacts K<2> energize magnets KRM to release the keys whereby .contacts MC1, MC2, MS are opened to release relay M. Relay M prepares a stepping circuit for IT in order that assig. nor AST may move into association with another key-board and release relays RT, UL. The equipment is now restored to normal ready for the registration of another bet. If a " doubles bet is set up in association with non-runners the associated relays in the competitors' groups 1DF-6DF, 1DS-6DS are not operated and in consequence the circuits from the key are switched over the relay contacts to relay CCA, Fig. 10, which operates relay CC. Relay CC operates the key release magnets KRM and closes the stepping circuit of the assignor AST over relay IT. " Forecast pool " betting. The apparatus may be adapted to register bets purporting to forecast the competitors which will occupy the leading positions in the same race. In this arrangement the wire X, Fig. 9, is omitted and connection is made at one point Y in order to prevent setting up of bets on the same competitor for more than one position. The bet is recorded by operation of appropriate keys in the groups KC1, KC2 and for bets on different competitors the subsequent operations are the same as those previously described. If however similar keys in the two groups are operated indicating a faulty backing on the same competitor, relay CCA is operated over contacts of CAF, CAS &c. relays and wire Y to effect release of the keys. " All combinations " betting. Bets on all possible combinations of runners in two races may be set up by a special T. I. M keyboard of the type shown in Fig. 2. In this keyboard only one competitor key is provided and no provision is made for different stake values, so that bets of only one value may be registered. Figs. 11, 15, 22, 23 show the additional equipment necessary for this type of betting, the apparatus in Fig. 15 comprising a counter assignor and Fig. 22 and 23 the competitor and totals control relay sets. The relays CAFCFF, CAFT-CFFT, CAS-CFS, CASTCFST, Figs. 22 and 23 correspond to the competitors of two events, the relays being operated in accordance with the actual competitors taking part in the events. The operator actuates key KCA which at contact CPC1 energizes M which brings about operation of STT, S. Relay S operates C, Fig. 11, to pull up SC which prepares the circuit of the counter assignor magnet DD, Fig. 15 and operates relay D, Fig. 11. Relay D completes circuits over assignor wipers ASC4, ASC2 (in positions corresponding to the " all combinations " keyboards) and assignor wipers D3, D4 in positions I, contacts of relays CAF-, CAS-, CAFT-, CAST-, for counter relay CU. Fig. 17 and " total " counter relay GU. The first combination i.e. 1-1 is registered on the counter CU used for the " double " bet 1-1. Further operation depends upon the counting operation in the manner previously described whereby relay R is operated over wiper ASC5 in series with magnet DD, instead of ASCD by reason of the wiper position. When the counter operation is completed, DD is deenergized to step the counter assignor. The counter assignor and the relay D, Fig. 11, interact to drive the assignor until bets are registered on all the counters. When operation of the last counter is complete, a circuit is closed over wiper D1 for magnet ASCD, ASA to bring about further operation of the assignor ASC to deal with the next group of keyboards. Operation of ASA energizes IC which interacts with D, DD to restore the counter assignor DD to position (1). In the event of non-runners all relays Fig. 22, 23 are not operated, and as wipers passes through positions corresponding to the non-runners, circuits are not completed to the relevant counting sets due to the positions of the relay contacts. These contacts however close stepping circuits for the magnet DD over leads e.g. 2.1522 to ensure that the assignor moves through all its positions. The ticket printing and issuing operation is initiated in response to the operation of all the counters. " All combinations " forecast betting. Since certain combinations in this type of betting cannot be permitted the leads over assignor D corresponding thereto are connected to lead 1.1515 to provide the stepping circuit. Corresponding leads to bank D4 are left disconnected. Alarm equipment. When all " doubles " or " combinations " bets are dealt with, relays M of all keysets are released to release STT which operates on " All bets received " signal. If the assignor AST fails to step within a predetermined time a pulse from slow pulse wire SP operates relay SAT which connects relay ZAT to slow pulse wire ZP. If due to a fault the assignor does not step by the time the Z pulse is received, ZAT operates audible and visible alarms and closes a circuit over wiper AST2 for lamp L. A faulty machine may be locked out by key LO. Similarly if a " doubles " or " all combinations " bet is not registered within a predetermined time, the alarms are operated due to the application of slow pulses over SP, ZP, Figs. 10, 12. A fault signal is also given in the event that relays such as ISU, 5SU &c. are operated by a fault. The Provisional Specification states that the ticket printing and issuing machine may be provided with test keys.
