Abstract: 419,547. Totalizators. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, SOUTHAM, A. A., 58, Larchwood Road, New Eltham, and BROOME, J. H., 80, Leyland Road, Lee, all in London. June 27, 1933, No. 18277. Addition to 366,222. [Class 106 (i).] In a system for totalling the registrations made on corresponding counting elements of two or more counters, the counting elements control the marking of groups of wires which are associated with follow-up switches, the switches being arranged in cascade and adapted to take up positions to facilitate totalling of the individual registrations. Fig. 1 shows the equipment associated with a set of denominational counting switches H1-DM1, and Fig. 2 an independent set of similar switches HII-DMII. These sets being adapted to count incoming signals. The equipment shown in Figs. 3 and 6 is arranged to indicate the sum of the signals recorded by the independent counting switches. Pairs of integrating switches US, USA(1); DS, DSA(1); CS, CSA(1) &c. individual to the denominational counting switches are provided and are adapted to hunt after the counting switches and also operate indicator lamps such as UL (0-9). Each pair of integrating switches acts as a single switch. Operation when one counter set only is operating. Assuming the counting switch U1 in the No. 1 counter, and its corresponding integrating switch US, USA(1) are in positions O, relay UR is operated over wipers 6, U1 of switches US, U1 respectively. Lamp UL (0) is also illuminated over wiper US(1). If, now, the counter U1 is stepped, UR releases and the stepping magnets of UD and UDA are operated. These magnets remove short-circuits across the lower winding of UR whereupon UR again pulls up and de-energizes the stepping magnets thus causing stepping, through one step, of the switches US, USA(1). In this position, relay UR is held operated and stepping ceases. If the counting switch U1 steps through several positions, the corresponding integrating switches move through a corresponding number of steps until alignment with U1 is obtained. As the integrating switches US, USA(1) progressively step from position to position, the lamps UL0-UL9 are caused to glow so that a continuous indication is given of the number of unit signals counted by the switch UI. At the tenth step of U1, the tens switch D1 is stepped in known manner and the corresponding integrating switches DS, DSA(1) follow the switch D1 in a manner similar to that of the switches U1, US, USA(1). The switches DS, DSA(1) control a second bank of lamps (not shown). Transfer from the tens switch to the hundreds switch C1 and so forth, and the operation of the respective integrating switches are similarly effected. Provision also is made for signalling half-units by a switch HI. Odd contacts only of this switch are connected in common to relay HIR which operates a lamp HL. Transfer to the units switch U1 is made at each even step of the switch H1. In the event of operation of counting set N‹2, Fig. 2, only circuits are progressively completed by the " units switch UII over successive wires in the group UG which are connected to the wipers of switches US, USA(1). If these switches are in the zero position the lamps UL0 ... are lighted progressively in accordance with the impulses counted on the switch UII. Similar effects are produced by the other denominational counters of sets N‹2. Both counter sets operating simultaneously. (a) Sum of signals not exceeding "nine." With both switches U1, UII off normal a circuit is closed over the appropriate wire in group UG and the corresponding wiper of the switches US, USA(1) for a lamp UL which indicates the sum of the positions of the counting switches. The contacts of the switches US, USA(1) are so wired that upon the advance of either counting switch the appropriate lamp is lighted. (b) Sum of signals in excess of nine. Assuming the counting switches are in positions corresponding to a sum of "nine" and a further signal is received on UII the lamp UL9 is extinguished and a circuit for the lamp ULO is completed over wiper UII in its new position and appropriate wiper of the switches US, USA(1). The circuit for operating the lamp UL0 under these circumstances includes a relay UAa. Relay UAa opens at ua1, the circuit of DR which brings about the operation of the stepping magnets DD, DDA and the stepping of the " tens " integrating switches DS, DSA(1) to record the "tens" digits. This operation is accomplished without effecting operation of the " tens " counting switch D1. Eventually, however, one or other of the counters U1 or UII will be moved from position 9 to position 0 indicating the summation of 10 units so that a transfer must be made to the appropriate higher denominational switches D1 and DII. In the event of switch U1 arriving at this position and operating Dl, the operated UA or UB relay is released and a holding circuit is provided for relay DR to prevent the further operation of the integrating switch DD, DDA. In the event that the UA or UB relay is not released until after D1 steps, operation of the switches would be initiated, but they would drive through nine steps to again align with D1. If, however, UII arrived to the zero position prior to U1 and caused the advancement of DII, the operations are initiated to restore the switches DS, DSA(1) (previously set due to the summation) into correspondence with the " tens " switch D1. When the switch UII moves into position 0 the operated relay UA is released and DR is released to initiate self drive of the switches DS, DSA(1) until they are in alignment with D1. The appropriate DL lamp is then lighted over wiper DII and a wiper of DS, DSA(1) in its restored position. Odd half-units added on the separate switches H1, HII cause the operation of HIIR which effects release of UR and the registration of a unit on switches US, USA(1). Operation of system provided with three or more counters. For each additional counter an additional integrating set is provided, this arrangement being such that the two groups of wires associated with each follow up switch may be marked in accordance with the positions of follow-up switches controlled by prior totalling operations. Indicating sum of highest denominational digits. When the sum of the indications of the highest denominational counter elements exceeds "nine," a relay is operated to light a " totals " lamp in the group CML.
