Abstract: 339,591. Broome, J. H. July 26, 1929. Totalizators.-In electric totalizators primary registers continuously accepting bets are in turn connected to a secondary register to effect a summation of their readings in such a manner that the summation may be repeated automatically during the time of operation of the primary registers. The multi-denominational digits from each primary register are transferred simultaneously to the secondary register through a counter switch, an assigner switch determines the order of connection of the primary registers after which digit correctors are connected to the secondary register to add digits carried over at transfers. A sequence switch then actuates an indicator and afterwards zeroizes the secondary register before preparing the circuits for the next summation. Primary registers. In the drawings in which corresponding relays and contacts are shown separated but related by appropriate designations, the relays U1, D1, C1, M1, Fig. 1, operating contacts u11, d11, - - to actuate driving magnets U1M, D1M - - , Fig. 3, corresponding to 2/-, ú1, ú10, ú100 tickets, are energized on the depression of corresponding stake Keys relating to one horse. The driving magnets thus step their respective wipers u1a, u1b, u1c; dia, dib, dic, - - according to the bet tickets issued. Transfer between the primary meters is effected over the banks u1b, d1b, - - the tenth bet on any of the denominations actuating its own switch magnet and that of the next higher digit over the last contact of its bank u1b, - - . The manner of registering bets of five units and effecting the transfer or carry-on from lower to higher denominations is described in Specification 339,622. The tickets issued at a second booth but relating to the same horse will be similarly registered by relays U2, D2 - - M2 and magnets U2M, D2M, - - T2M on wipers u2a, u2b - - ; d2a, d2b, - - &c. The banks of the wipers ula, dla, - - relating to each booth are multipled to corresponding banks cra, crb, - - of a counter switch CR having a driving magnet CRM, only two horse register banks HR1, HR2 being shown. Starting betting operations. When betting commences a start key is thrown closing contacts sk1, sk2 - -. Contacts sk1 energize a relay MS, Fig. 3, closing contacts ms2, to operate an interrupter motor IM which periodically close contacts IC1, IC2, - -. Assigner switch. On the closing of contacts IC1 an assigner driving magnet ASM is energized over a wiper asf and the first contact of its bank. When the contacts IC1 open the corresponding wipers asa, asb, - - are stepped to the second contact connecting + ve to the wipers u1a, d1a, - - thus marking the contacts of the banks cra, crb, - - corresponding to the number of tickets registered by HR1. Counting switch operation. A circuit is now prepared over wipers asg, sc4, crh and on the next closure of contacts IC2 the driving magnet CRM is energized and on its release advances its wipers cra, crb - - one step when it prepares a circuit for itself over a homing wiper crh so that the counter switch now continues to rotate in synchronism with the closing of the contacts IC2. When the wipers cra, crb - - reach the marked contacts of the primary register HR1 the corresponding relays UT, DT, - - are energized and lock up over contacts ut2, dt2, - - and their secondary windings Fig. 2 actuate contacts ut1, ut2, - - , dtl, dt2 - - ; &c. Secondary or counter register. The first step of the counter switch CR has energized a relay ON closing contacts on1, - - on9. These prepare circuits to the various digit meters CRUM, CRDM, CRCM, CRMM, CRTM, CRHM of the counter register, which, with the contacts ut3, dt3 - normally closed, are stepped in synchronism with the counter magnet CR, over the interrupter contacts IC3. The wipers crua, crub, - - ; crda, crdb - - ; - - , of the counter register are thus advanced until the wipers of the counter switch CR reach their marked contacts when the corresponding contacts ut3, dt3, - - open. When the counter switch CR has completed one revolution the counter register meters will have thus taken up positions corresponding to the markings in the banks cra, crb, - -. When wiper crg steps to normal again relay ON is released so that all relays UT, DT - - HT return to normal again. When the switch CR comes on to the last step a circuit is made over wiper crg, contact on 1 and on the next closure of contacts IC1 the assigner magnet ASM is energized and on release steps its wipers on to their third contacts when the banks cra, crb, - - are marked corresponding to the tickets registered on the primary register HR2. The counter switch is again on its first contact and its driving magnet CRM is energized over wiper asg, and wiper crh so that the switch CR again rotates step-by-step during which time the secondary meters CRUM, CRDM, - - are advanced correspondingly to the digits registered on the primary register HR2. Other horse meters also multipled to the banks cra, crb, - - would have their wipers connected to the fourth and subsequent contacts of the assigner wipers asa, - - asf, and, the assigner being advanced one step at the end of each revolution of the counter switch CR, the totals of all the primary registers would in turn be transferred to the counter register as above described. The assigner next passes on to the fourth contact (here a spare one, resulting in energization of all the relays UT - - HT on the first step of the counter switch and therefore no registration on the secondary register). The remaining contacts are connected to digit correctors. Digit correctors. These are necessary to render the secondary register correct. Any digits carried forward by the secondary register magnet CRUM are registered by magnets DUAM (tens), DUBM (hundreds), - - Fig. 4, the other denominational secondary register magnets CRDM, CRCM, - - having digit corrector magnets DDAM, DDBM, - - ; DCAM, DCBM, - - actuating their associate wipers. The assigner steps on to the fifth contact. During the following rotation of counter switch CR, the marked contacts in the banks crb, crc, - - correspond to the numbers registered on the digit corrector DU, subsequent steps of the assigner consecutively connecting the digit correctors DD, DC, - - DT, for their totals to be counted on the secondary register. The counter CR now steps to its starting position as the assigner steps to its tenth contact energizing a relay R. The relay R operates contacts r1, - - disconnecting the secondary register and digit corrector magnets. Sequence switch. On the next closure of contacts IC4, the sequence switch driving magnet SCM, Fig. 4, is energized over wiper sc1 and contacts r2, and advances, with its associated wipers sc1, - - two steps. A circuit is now made through wiper sc2 contacts iut1, idt1, - - of relays IUT, IDT, - - , indicator stops magnets UA, DA, - - , HA, and relay MS'. The latter closes contacts ms<1>1 to start the motor RI which drives the indicator. Indicator. The indicator is of the roller blind type comprising a roller for each digit denomination driven by the motor R1, through a clutch, normally open but closed by the energization of the corresponding stop magnet UA - - HA. The movement of each roller corresponding to a change of one digit is adapted to send back an impulse, by closing a corresponding contact ual - - ha1, to a corresponding indicator controller switch IUM - - IHM. The rollers of the indicator are thus rotated, closing the contacts ua1, da1, - - , ha1, to energize the magnets IUM, IDM - - , IHM which step the wipers iua, iub; ida, idb; - - iha, ihb; a number of times equal to the digits passed during rotation of the indicator. These wipers rotate until they come to the contacts marked in the corresponding banks crua, crda, - - of the secondary register when a circuit is made through wiper sc3 the corresponding banks crua, iua; crda, ida; - - to relays IUT, IDT, - - . The latter operate their contacts iut1, iut2; idt1, idt2; - - to de-energize the corresponding stop magnets UA - - HA which arrest their associated indicator rollers. Ultimately, when all the magnets UA - - HA, have been operated, the indicator rollers will each have rotated to a position corresponding to the setting of the associated counter register meter. The contacts iut2, idt2, being now closed a circuit is made for the sequence magnet SCM which advances to the fourth step. Wipers sc2, sc3 are disconnected so that the indicator and indicator controller switches IUM - - IHM are set and motor R1 stops. Zeroizing the secondary register. On the fourth step of the wiper sc1 a circuit. is made through wiper sc1, over the homing wipers cruc, duac, - - dueb; crdc, - - dddc; crcc - - ; crmc; crtc - - ; crhc which home " their associate wipers in turn when a circuit is again made for the sequence magnet SCM which steps into fifth position awaiting restoration of relay R. A circuit is now made over wipers asg, Fig. 3, sc5 to magnet ASM. Accordingly at the next actuation of the interrupter contacts IC1 the assigner is stepped to its. starting position releasing the relay R when the sequence switch magnet SCM steps to its normal position. Totalling operations on the secondary register are now re-commenced, wiper sc4 being in position for starting the switch CR, and giving another indication on the indicator. Betting having finished when a steady indication is shown on the indicator, the start key and contacts sk1, - - are released, the relay MS de-energizing to stop the interrupter IM when the wipers ash are at normal. Lamp indicators. Depression of a key LIK will illuminate a small lamp indicator L1 for the secondary register total, and individual horse totals may be shown on an indicator LS by depression of the appropriate keys DK1, DR2, Fig. 3. Resetting. To reset the horse registers and the indicator to zero, a reset key controlling contacts rik1, rk2, - is made. Contac
