Abstract: 340,515. Totalizators. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and LIMB, F., Holmwood, Fellows Road, Beeston, Nottinghamshire. Sept. 21, 1929, No. 28645. [Class 106 (i).] Uni-denominational bets are collected and registered by a plurality of mechanically independent electromagnetic switches each controlled from a different source, means being provided to add the totals of all the registering switches together. The switches are arranged in sets and the sets form groups, means being provided to effect transfer during registration and also when betting has finished should the residual registrations total more than the number of units in the next denomination. The invention is described with reference to Specifications 340,280, 340,288, and 340,289, and consists in grouping receiving and registering switches when all the ticket machines cannot be accommodated on one switch, different indicating control means being employed. Individual horse receiving switches. Fig. 1 shows two 50-point switches AE and F, relating to 2/- bets on one horse, to accommodate 100 ticket machines, operating as in Specification 340,280 to actuate registering switches VA, VB respectively, over contacts of relays GX and HX. Transfer means. A transfer is necessary whenever the sum of the totals of the registering switches VA and VB passed ten. When the sum is nine, wipers va4, vb4 will rest on comoned contacts, and on the next actuation of relay GX or HX to actuate either registering switch VA or VB, contacts gx3 or hx3 close a circuit over wiper vb4, line 421 say, wiper va4 to relay AA which operates, locks up over contacts aa1, ar1, and is released by the operation of relay AR when the transfer impulse has been registered on the ú1 registering switch as in Specification 340,280. If the sum of the registrations on VA and VB was eight however, and both VA and VB were operated simultaneously wipers va4, vb4 would not stop on comoned contacts. To operate the relay AA in this case wipers va3, vb3 are provided, the contacts gx2 and hx2 being operated together, closing a circuit over wipers vb3, va3 (connected together when the sum total registered on VA and VB is eight) to the relay AA. Individual horse indicator ; control. The indicator is of the monogrammic lamp type controlled by relays energized over leads 33 .. 38 as in Specification 340,280, and is operated at the end of betting by throwing a key K1 to the right to operate a relay FD. If the registering switch VA is in an off-normal position a relay DC is operated over contact fd1 and interrupter contacts va1, contacts dc2 energizing the magnet of the switch VA over wiper va2 which opens its contacts va1 releasing relay DC. Consequently the switch magnet VA releases, advances its wipers one step and closes contact va1. This cycle continues, the registering switch VA being stepped to its home position. A circuit is now made for relay DC over wiper vb5 and contacts vb1, and for switch magnet VB over wipers vb2 (if off-normal) and va2 the switch VB being similarly stepped to zero position. The impulses through the relay DC which have " homed " switches VA and VB have also actuated contact dc1 to step the indicator control switch V a number of times equal to the sum of the complements, with regard to 10, of the digits registered on VA and VB, (the switches VA, VB being ten-point switches). Thus, if VA and VB register 3 and 4 units, say, before key K1 is thrown, during homing, the switch V will step 7+6=13 times, and be on its third step from normal. The digit to be displayed is 3+4=7 which is the complement of 3 so that the digit displayed on the indicator is the complement with regard to 10 of the position of the switch V from its normal contact. If the sum registered on switches VA and VB is 6+8=14, say, the necessary transfer has already been accomplished over wipers va4 and vb4, or va3 and vb3, and the switch V moves on to its 4+2=6th contact resulting in a digit display of 4. The display is controlled by the wipers v3, v4 which selectively energize the leads 33 .. 37 according to the position of the switch V. During betting operations zero is displayed on the 2/- indicator, the wipers v3 and v4 (in home position) and the lead 38 being energized over a lead made alive when a ú1 bet is registered or a transfer effected from the 2/- registering switches. Pool receiving switches. To accommodate 100 ticket machines for 2/- bets, four receiving switches UA, UB, UC, UD, Fig. 2, will be necessary, their operation being identical with that described in Specification 340,280, the associated registering switches WA, WB, WC, WD being operated over contacts pa2, pb2, pc2, pd2 respectively when the corresponding relays PA, PB, PC, PD release. Pool transfer means. The switches WA, WB and WC and WD are arranged in pairs, and transfer takes place during betting over leads 44 and 45, energized over wipers wa3, wb3 ; wa4, wb4 ; wc3, wd3 ; wc4, wd4 connected and operated similarly to those for the individual horse counters, the impulses over these lines operating the ú1 pool receiving switches UE, UF as in the above-mentioned Specification. When betting has ceased and the sum of the 2/- bets registered on WA, WB, WC, WD is to be displayed, a further transfer will be necessary if the sum registered on the two pairs causes a change from ten to zero. This is accomplished over line 46 as described below. Pool indicator control. Betting having ceased the key K2, Fig. 2, is thrown to the right operating a relay FE. A relay DA is energized over interrupter contacts ta1 of a sequence switch TA, contacts fe1, fe2, line 48, wiper wa2 (if off normal), interrupter contacts wa1, and normal contact of wiper ta3. The magnet of switch WA is operated over contacts da1 and wiper ta4 and opens its contacts wa1 releasing relay DA which releases its contacts da1 the registering switch being stepped. This interaction of relay DA and switch magnet WA continues until switch WA is homed when a relay SA is energized over wipers ta2, wa2 and line 48. Sequence switch magnet TA is operated over contacts sa1, and it opens contacts ta1 releasing relay SA which releases magnet TA whose wipers are thus moved on to their second step when a circuit is made for relay DA over interrupter contacts wb1, which now interacts with switch magnet WB operated over wiper ta4 to home the switch WB. During the homing of WA and WB, the switch RA, operated by relay DA, has advanced a number of steps equal to the sum of the complements, with regard to 10, of the bets registered on WA and WB. The sequence switch now steps on to its third contact, when the switch RA is homed, a counting switch U being synchronously advanced to register a number equal to the complement, with regard to ten, of the position of the switch RA from its last normal position. When switch RA is homed, the sequence switch is stepped to the next contact when the switch WC is homed, and, on the next step of sequence switch TA, switch WD is homed the switch RA being meanwhile stepped as for WA and WB. On the next step of sequence switch TA, the switch RA. is homed the counter switch U being operated as before. Thus if switches WA, WB .. registered 6, 7, 5 and 3 bets, say, the switch RA on hoining of WA, WB moves 4+3 =7 steps, and on homing of WC, WD, 5+7=12 steps, that is 2 steps past normal. On homing of switch RA the switch U moves 3+8=11 steps. The digit to be displayed is 6+7+5+3=(21-20 =1. The switch U rests on its first contact from normal having rotated once. The wipers u3, and u4, controlling a lamp indicator by means of relays operable over leads 133 .. 137 analogous to leads 33 .. 37 as for the horse totals therefore display a digit corresponding to the position of the wipers, the first step from normal thus displaying a digit 1 and so on. In the above example two transfers were necessary, the first was accomplished during betting over lead 44, the second " residual" transfer is accomplished when switch U passes its tenth position over wipers ta5, u5, line 46, relay QA which actuates the ú1 counter XA over contact qa2. When the switch WD was homed the relay DT was operated over lines 49, 48 and locked up over contact dt3 and key K2. Contacts dt1, dt2 close to commence the sequence of operations, similar to that for 2/- bets, for the display of the ú1 total. Extra keys da4, da5 and wiper ta6 control similarly operable distant displays. Resetting means. The keys K1, Fig. 1, and K2, Fig. 2, are thrown to the left, releasing relays FD, FE, and DT, causing the display lamps to be extinguished and operating relays HR and HS. If the display switches V and U are off-normal they are returned to zero, the magnet circuits being over homing wiper v2, contacts hr1 and homing wiper u2, contacts hs1 respectively. The apparatus may be applied to uses other than horse racing.
