Abstract: 640,952. Calculating-apparatus ; totalizators. SIEMENS BROS. & CO., Ltd., and HAILEY, A. M. Nov. 7, 1947, No. 29668. [Class 106 (i)] An electric totalizing system comprises a number of counting-signal originating points forming a section and given access to a register by equipment common to the section, the register retaining the units part of the sum only and when transfers occur transmitting the tens to a second register common to several sections, the transmission being made directly without passing through access equipment. The invention is shown applied in Fig. 1 to a totalizator system comprising five sections. Each section comprises a group of ticketissuing machines, i.e. signalling originating points, TIMA, access equipment CAA, competitor - bets counting equipment CA and a lead GTCA to a grandtotal counting apparatus, not shown. The corresponding items in another section are TIMD, CAD, CD and GTCD. The counting equipment CD, however, registers units only and transfers tens along a line d to the tens register of the counting equipment CA which is thus common to the two sections and which itself registers units and tens. Units from both counters CA, CD are summed in a summing apparatus SAD, the units u therefrom passing to a summing apparatus SI, the tens d going to the counter CA. Tens d and hundreds c pass from the counter CA to the summing apparatus SI. Thousands m from CA and SI pass to a thousands summing device TC which also receives as shown the thousands which have originated in other sections. The units, tens and hundreds u, d, c from the summing device S1 pass to a grand summing apparatus S2 to be combined with entries coming from the fifth section TIMC. Finally, units, tens and hundreds from the grand summing apparatus S2 and thousands from the summing device TC are led to operate an indicator I. The third and fourth sections TIMB, TIME are grouped as shown in the same way as the first and second sections. The counting apparatus CD (and CE) registering units only, Fig. 2, comprises a counting switch of known type having four pairs of wipers U1 ... U4 for respectively transferring, homing, counting and transmitting to the summing apparatus SAD. Receipt of a units bet signal energizes a relay U/4 contacts ul of which close the circuit of the switch-stepping magnet UDM which at contacts udm removes a short-circuit preventing operation of a relay R. The bets signal has also been passed to the grand total counter. When the latter has registered' the signal, a signal is sent back over a line gtc, u4 to energize the relay R which sends a releasing signal back to the ticket-issuing machine. The bets relay U/4 is accordingly released, the contact ul de-energizes the magnet UDM and the wipers are stepped one step. The counting-apparatus CA, Fig. 3, (and CB), comprises units, tens and hundreds counting switches, each having three wipers U1, U2, U3 ; D1, D2, D3 ; C1, C2, C3, respectively, U1, D1, C1 being for transferring, U2, D2, C2 for homing and U3, D3, C3 for counting. Limits bets coming direct from ticketissuing machines in section TIMA energizes a relay U/5 to cause stepping of the units wipers U1, U2, U3 by means of a circuit similar to that shown for advancing the units switch of Fig. 2. A tens bet received in CA direct from a ticketissuing machine energizes a relay DA/5 which at contacts da1 causes operation of a relay MA/4. Contacts ma4 of the latter close the circuit of the stepping magnet DDM of the tens switch D1, D2, D3. The magnet is released, and the switch stepped on, upon the receipt of a signal from a grand-total counter and upon the release of the ticket-issuing machine. When the units counter CD, Fig. 2, registers ten, a signal from the transfer arm U1 energizes a relay DB/2, Fig. 3. When the units switch U1, of counter CA, Fig. 3, reaches a transfer point, the relay DA/5 is energized to step on the tens switch D1, D2, D3 as just described. This relay is also energized when a tens bet is received by a relay D/4, Fig. 2, directly in CD, the relay closing contacts d1, Fig. 2, in the circuit of relay DB/2, Fig. 3. Relay DB/2 energizes a relay MB/4, contacts mb4 of which cause the stepping of the tens switch D1, D2, D3 in a manner similar to that caused by the contacts ma4 described above. The relays MA/4,MB/4 are so interconnected that, if a signal arrives at one while the other is operating, operation of the first is delayed until the other has released. The units registrations on counters CD, Fig. 2, and CA, Fig. 3, are summed in the apparatus SAD, Fig. 4, the units of the sum being passed to the device S1, Fig. 1. The contacts of the units wiper U3 of the counter CD, Fig. 2, are connected respectively to a set of relays B0/9 ... B9/9, Fig. 4, each operating its own group of contacts, e.g. in the case of relay B9/9, contacts b91 ... b99. All the " 1 " contacts b01, b11 ... b91 from the several relays are connected to the " 1" contact of the units switch U3, Fig. 3, all the " 2 " contacts b02 ... b92 to the " 2 " contact of U3, and so on. Thus if " 4 " is registered in counter CD, Fig. 2, relay B4/9 is operated and contacts b41 ... b49 are closed. If " 3 " is registered in counter CA, Fig. 3, all the " 3 " contacts b03 ... b93 are energized. A circuit is thus completed through contact b43 and this connected (by lines not shown) to a point X joined via a resistance Y7 to the " 7 " contact in a summing switch in the summing device S1, Fig. 1. The contacts b01 ... b99 are so connected to the points X that the contact in S1 representing the sum of the units from Figs. 2 and 3 is energized. When the said sum includes a transfer, the point X is connected to one of four windings UBa ... UBd of a relay UB (not indicated) or to one of five windings UAa ... UAe on a relay UA (not indicated). Since transfers are normally taken care of by the transfer-wiper connections in Figs. 2 and 3 the relays UA, UB are ineffective during betting, but if, at the close of betting, the sum of the units registrations standing on the counters of Figs. 2 and 3 exceeds " 9," the relays UA, UB pass on the transfer. The summing apparatus S and the grand summing apparatus S2 are similar to that shown in Specification 419,547. Thousands transfers from the counters CA, CB, CC are combined with thousands signals from the summing apparatus S1 and S2 in the thousands register TC, Figs. 1, 7. The transfers from CA, CB, CC energize respective relays STA/3,STB/3,STC/3 which cause the operation of the stepping magnet MDM of the thousands registering-switch wipers W1 ... W6. Means including relays MA/4 MB/4 MC/4 and associated contacts are provided to take care of transfers arriving simultaneously at the relays STA/3 ... Contacts " 0," " 1," ... in the bank of wiper W1 are connected to " 1," " 2," " 3," ... of W2 and to " 2," '' 3,'' " 4,'' ... of W6. Relays in the summing apparatus S1, S2 cause potential to be changed from wiper W4 to W5 when a transfer is to occur in S1 or S2, and from W5 to W6 if a second transfer arises before the release of the relay operated by the first transfer. If the first transfer is made from a counter CA, CB, CC, the magnet MDM steps the wipers to contacts 1 and the indicator hunting switch operates as a follow-up device to search for positive over wiper W4 to display the thousands digit " 1 ". If one or two transfers then come from the summing apparatus S1, S2, searching is done over wiper W5 or W6 respectively and, because of the stepped connection between the contacts of the banks W4, W5, W6, " 2 " or " 3 will be displayed. Transfer of tens of thousands is controlled by relays STRA/1 and STRB/2. At the end of betting, a switch abr, Fig. 8, is closed to energize a relay CSP/2 which, through contacts csp energize a transfer relay DTA. If any relay UA, UB of the summing apparatus SAD is at this time operated, a transfer has been prepared in SAD, but not passed forward. Contacts ual or ubl, Fig. 4, are thus closed and upon the energization of the transfer relay and the closing of contacts dta1, a circuit is completed for relay DA/5, Fig. 3, to pass the transfer to the counter CA. Resetting. The system is reset by the operation of a key which energizes resetting relays RS/3, Figs. 2, 7 and RS/9, Fig. 3, to close contacts, e.g. rs1, Fig. 2, in the circuits of the homing wipers, e.g. v2. of the several switches. Specifications 340,298 and 367,355 also are referred to.
