Patent GB-388538-A (GB)
Abstract: 388,538. Totalizators. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 64, Heathwood Gardens, Charlton, both in London. Jan. 8, 1932, No. 639. [Class 106 (i).] In a totalizator system competitor registers are provided for only the lower value denominational bets (units) transmitted from the ticket issuing machines, bet signals of higher denomination (tens, hundreds, ..) and transfer signals from the registers operating directly the public totals indicators which display only the higher denominations of the competitor totals. The exact competitor totals are displayed on a miniature indicator for the use of the control officer, the lower denominations of these totals being controlled by the registers and the higher denominations revertively from the public indicators. General arrangement. The ticket-issuing machines are assumed to be operatively connected to the registering and indicating equipment through assigner mechanism (not shown). For units and tens bets on one competitor, markings are applied from the assigner to lines uw, dw, respectively, and persist until a revertive impulse from the competitor and pool registers operates the assigner release relay RR. The competitor register comprises a switch US (us1 .. us4). The corresponding public indicator is of the thermometer type and comprises a moving band mounted on rollers, one of which is adapted to be driven from a constantly rotating shaft when a clutch magnet CC is energized. Registering units bets. A units bet marking over line uw operates a relay U, contacts u1 thereof energizing the drive magnet USDM. A differentially connected relay I operates as the interrupter contacts usdm open, and when the grand total (pool) counter also operates to register the bet, thereby closing contacts rlg, r2g, the release relay RR operates over the circuit r1g, bank and wiper us3, il, bc1, and locks over rr1, r2g, and bc2, i2. Relay RR now initiates operations in the assigner whereby the marking on line uw is removed. Relay U thereupon releases ; USDM is released at u1 and steps its wipers to the next position; relay I falls off breaking the energizing circuit of RR at i1 and one of the locking circuits thereof at i2, and when the pool counter has completed its registration contacts r2g open ; RR then releases to step the assigner and the apparatus is ready for the reception of further bets. Public indicator ; operation. When a tenth units bet signal operates relay U, the clutch magnet CC is operated over the circuit r2, u2, wiper us2, g2 contacts A, closing contacts c1, c2. While the indicator is moving to a fresh display the contacts B are closed, and contacts A thrown to close a locking circuit for CC at c1. Over the circuit RSC, B, g3, a relay R is operated and locks over r5, u4, contacts r4 thereof operating a relay G which locks over g1 and at g3 opens the operating circuit of relay R. When the pool counter operates contacts r1g, the release signal to RR is sent over r1g, r1, us3, i1, bc1. RR functions as before to release relay U whereupon switch US steps and relay R is de-energized at u4, releasing RR at r2. For tens bets assigned directly to the public indicator the relay D is operated, closing the operating circuit for CC over r2, d3, g2 ; contacts d2 close the locking circuit for relay R which operates as before, and the release circuit for RR is made over rlg, r1, d1, bc1, causing D, and therefore R, RR to release. When relays U or D (which cannot be operated together), and R have released, further units bets may be registered even though the indicator may be still moving, but a tens signal cannot be accepted until the indicator has come to rest when the relay G is released at c2. Exact indicator. This consists of denominational banks of lamps U1, T, H, TH, the units bank U1 being controlled over wiper us1 of the register. The wiper D1 controlling the tens display T is associated directly with the moving band of the public indicator and is moved thereby over one step for each fresh display thereof. Suitable transfer mechanism is provided between wipers D1, C, M to control the hundreds and thousands banks H, TH respectively. A doll's-eye indicator may alternatively be used. Precautionary arrangements ; resetting. When the registering switch US rests on surplus contacts a relay BC is energized over wiper us1, and at contacts bc3, i2 a circuit is made for drive magnet USDM which steps by interaction with relay I to the next operative contact. Contacts bc4, bc5 render markings on wires uw, dw ineffective until this stepping is completed. Contacts u3, d4, r3, i3 are adapted to operate an alarm AL should the relays corresponding thereto remain operated for an abnormal length of time. For resetting the register a suitable marking is applied to the right-hand wire' RS when US homes by interaction with relay I and indicates normality over the left-hand wire RS. Closure of key TJ provides a continuous stepping circuit for USDM for test purposes. Contacts N1, N2 are closed while the public indicator is off normal, contacts N2 closing the circuit of the off-normal indicating relay ON. To reset the indicator switch RSC is thrown to energize the clutch CC over contacts N1, and c1 or A, until the indicator is at normal. Specification 357,616 is referred to.
