Abstract: 367,488. Electric totalizators. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, BROOME, J. H., 64, Heathwood Gardens, Charlton, and CLARK, R. 1. H., 148, Evering Road, Stoke Newing- ton, all in London. Dec. 9, 1930, No. 37121. [Class 106 (i).] In an arrangement whereby the ticket machines are grouped, each group being served by its own common signalling lines terminating in a set of relays, an assignor is provided for each group of machines and another assignor serves to connect up the sets of relays singly with the counters. General. The essential contacts and relays of one ticket machine are shown in Fig. 1, and the machine assignor is illustrated in Fig. 2. The competitor signalling lines 1, 2, &c. lead to batteries of competitor relays, two only of which are shown, namely, CRS1 and CRS2, Fig. 4, while other common lines such as 3-25, 4-25 lead to relays in the assembly CORS, Fig. 5, or to stake value relays, Fig. 7, common to all the machines. The assignor COSA for connecting the groups of relays CRS, CORS one at a time with the counters, Fig. 9, is shown in Fig. 6. Ticket-machine keys. These consist of competitor keys H1 .. H40, Fig. 1, keys W, P, EW for win, place and each-way bets, keys SB and MB for single and multiple bets, and a series of stake value keys SV (2/-, 10/-, &c.). General control. Betting is opened by setting the key OK, Fig. 11, with or without closure of the place-betting key PK, this latter key by relay DP preparing the signal lines to the place and each-way relays P, EW. Lamp OL, Fig. 3, in each booth now lights up and relay A is energized to close circuit at contact a1 for slow relay B, at a2 to complete circuit for unlocking the ticket machines, and at a3 to open the machine-locking line. Relay B now locks up at b1 and at b2 opens the unlocking circuit and prepares the locking circuit. To close down, the key CK is thrown and similar action of the relays A and B follows to lock the machines and prevent closing of the unlocking circuit. Ticket-machine actions. With the desired keys depressed, master contact ml, Fig. 1, changes over to mark a contact in bank B of the machine-assigning switch, Fig. 2, m2 closes circuit for relay ST and m3 prepares the circuit of one winding of relay R. The assignor now steps, as described later, and when the marked contact in bank B is found relay S operates to connect at s1 .. s5 positive potential through the keys to the signalling lines. The circuit of the other winding of revertive relay R is prepared at s6, and when the bet has been registered, this relay at contact r1 opens circuit for relay S, at r2 closes a locking circuit, and at another contact sets the machine in operation to issue a ticket. If the bet should be laid on a non-runner a relay C, Fig. 4, will be operated to complete a circuit at c1 to a cancelling magnet CM. Similar action occurs if a place or eachway key is depressed without previous setting of general control key PK, the relay C being then energized through resting contacts of relay DP. Ticket-machine assigning. When relay ST operates, as above stated, contact st2 prepares circuit for relay SA to receive an " S " pulse from the time control. If no bet is set up in the first machine the contact m1 at normal would cause operation of relay I and therefore, through contact il the actuation of magnet DM and stepping of the switch. This process continue 3 until a contact in bank B is reached that is wired to a machine having its key contacts operated whereupon the switch stops and the relay S in the machine in question operates to send the bet signals. Upon receipt by relay R of the revertive signal, contact r1 swings over to de-energize relay S, allow the switch to continue its stepping and prepare a locking circuit for relay SA, contact sa2 of which prepares the relay ZA so that if the switch does not advance before the Z pulse is received the relay operates to give an alarm. Registering a single-unit bet. The keys having been set up and relay S energized a relay such as CR24, Fig. 4, in one of the competitor relay groups will be operated, as also will be relays SUW, SUP, Fig. 7, pertaining to single-unit win and place bets respectively and relay W for a win bet. Contacts cr<24>1, cr<24>2 will now prepare circuits for win and place counters CWC, CPC and contact cr<24>3 will operate relay CC, Fig. 5. Contacts w1, w2 close points in circuits to the competitor win and grand total win counter, and further points in these circuits are also closed by contacts cc1, cc3. A time-alarm circuit for relay SAC is prepared at cc5 and further cc contacts are provided for various purposes. Group relay assigning. Relay CC having been energized as above described, contact cc6 operates relay STA to close at sta1 a circuit through wiper C contacts gl, cc1, w1, cr<24>1 and suw1 to register the bet on counter section U. A similar circuit is likewise completed through bank E to section U in the grand total counter GTWC. Relay SC being operated over contact cc8 and wiper B, contact sc1 operates relay STC which then locks up at stc1 and prepares at stc2 a release circuit for the ticket machine, at stc3 a step-on circuit for the machine assignor, and at stc4 a circuit for relay G. If the relay group had not been operated contact cc1 at rest would have caused relav IC to function to step the switch until an operated contact cc1 was found. Both counters having registered, their release contacts complete a circuit to magnet SDM which then operates and breaks the signalling circuits at sdm1, and prepares to advance the switch to find the next relay group with operated contact cc1. In the group just disconnected, relay SC being now de-energized, its contact sc2 sends a release signal to relay R, Fig. 1, and a contact sc3 operates the relay G to break the registering and starting circuits in Fig. 5. The ticket machine being released, relay CR24 with the other bet relays relapses and brings down relay CC and so allows the switch, Fig. 6, to step. Slow relay STC is released by contact cc7 which also completes a circuit to the machine assignor magnet DM, Fig. 2, and when relay STC finally falls and the magnet de-energizes the machineassigning switch advances. Multiple-unit bets. Relay MB having been energized by the use of key MB, the release signal from the counters is directed at mb1 over wire 3À25 to wiper D, Fig. 2, and thence to an impulse-counting device in the machine. Operation of this device disconnects positive potential from contact S3 and thus causes relay W, P, or EW in the relay group and the counters to relapse and allow the device again to operate. This action continues until the last signal but one is sent, whereupon the device will divert the revertive signal from mb1 to wiper C and wire 4À25 to magnet SDM so that the assignor, Fig. 6, may subsequently step as in singleunit bets. Specification 367,355 is referred to.
