3 Claims. (Cl. 235-433) This invention is for improvements relating to totalizer counting and displayin arrangements, and one of its objects is to provide improved transfer arrangements.

In order that the features of the invention may be made clear a brief description of the function of a totalizer will first be given.

The totalizer is primarily for use in public meeting places for counting the number of sales of commodities, etc., or the number of investments made by the people present. With one arrangement initiations of such proceedings are made at ticket machines disposed at convenient places termed boot and upon such a step being taken a ticket is endorsed with particulars of the transaction such as the amount deposited and details specifying the transaction entered into. As each negotiation is made the totalizer displays to the public both the total amount deposited on each investment, for example, and also the sum total or pool of all of the deposits received.

It is convenient to consider the totalizer as comprising a number of ticket machines, totaliz- 7 ing apparatus for the amounts deposited on each individual investment, the pool totalizing apparatus and the indicator or display.

Each ticket machine is provided with a set or a number of sets of keys. Each key is numbered and is allocated to a particular investment or being made in connection with a transaction which for the purpose of this specification will be designated by the No. 1 a key corresponding to that number in a set of keys arranged for 1 investments is operated and causes a ticket to be endorsed and issued and the totalizing apparatus to register the amount of the investment and add it to the total for the particular transaction specified and to the sum total of the pool.

The display or indicating apparatus is located in a prominent position and is controlled by the totalizing apparatus. There may be several displays at different localities associated with the same totalizing apparatus.

When desired, for example at the end of th proceedings, arrangements are provided to set the apparatus to zero in readiness for further proceedings.

According to the invention a transfer circuit arrangement for a totalizer comprises one relay adapted to operate fully prior to the movement of a registering switch into a zero position and to make an outlet of a connecting switch associated with the next denomination and a second relay adapted to cause the release of the first relay after the connecting switch has found the marked outlet.

According to one feature of the invention a transfer circuit arrangement for a totalizer comprises one reiay adapted to operate fulLv prior to the movement of a registering switch into a zero position and to mark an outlet of a connecting switch associated with the next denomination and a second relay connected in series with the conductor marked by the first relay and adapted to cause the release of the first relay after the connecting switch has found the marked outlet.

According to another feature of the invention a transfer circuit for a totalizer comprises one relay adapted to operate fully. prior to the movement of a registering switch into a zero position and to mark an outlet of a connecting switch associated with the next denomination and a second relay adapted to cause the release of the first relay after the connecting switch has found the marked outlet and means whereby all the totals received by the registering device of the higher denomination from that of the lower denomination are registered even when the device of the higher denomination is registering for another or a plurality of other sources.

The invention will be more completely understood by referring to the following description of one method of carrying it into effect which should be read in conjunction with the accompanying drawings. This description is, however, given by way of example only, and various modifications may be made by those skilled in the art without in any way departing from the spirit of the invention. It should be mentioned also that this arrangement is identical to that disclosed in the specifications of U. S. patent application Nos. 482,878 and 482,880 of September 18th, 1930 which claim different features from those claimed herein.

Referring now to the accomp y drawings,

Figures 1 and 2 show a schematic layout of the totalizer.

Figures 3 to 10 inclusive, show circuit connections of various parts of the totalizer.

Figure 3 shows the circuit of three receiving switches RA, RB and RC for investments in the same transaction and the connections to investment keys at ticket machines for 2/-, 1 and 10 investments respectively:

Figure 4 shows the circuit of a registering switch UA for investments in an individual transaction. The same drawing is applicable for 2/-, 1 or 10 investments:

Figure 5 shows the circuit of a relay group and relative display lamps. This drawing may be used for all denominations and also for amounts 50 tional registering switches are shown at UD1 and switch UD for amounts of 100 or 1000, either invested in an individual transaction or for, the total pool:

Figure 7 shows the circuit of three receiving switches RTA, RTB, RTC for the total pool investments of 2/-, 1 and 10 respectively, while Figure 8 shows the circuit for a registering switch UT for the total pool investments of 2/-, 1 and 10:

Figure 9 is an inset portion at the top of Figure 4 and represents the circuit of a transfer equipment associated with the registering switch for 2-, 1 and 10 investments in individual transactions:

Figure 10 is an inset portion at the bottom of Figure 4 and shows the resetting key and associated relay.

Figure 11 shows the arrangement of lamps of a digit display and Figure 12 shows an example of a. numeral being exhibited on a digit display.

Figure 13 is a table which relates to Figure 11.

Figure 14 is a drawing showing the way Figures 3 to 10 inclusive should be arranged in order to facilitate tracing the various circuits to be described. I

The schematic layout illustrated in Figures 1 and 2 will now be described. The figures should be arranged so that Figure 2 is on the right-hand side of Figure 1.

Six ticket machines are shown in Figure 1; TMl, TM2 and TM3 represent ticket machines for 2s. 0d. investments, TM4 and TM5 represent machines for 1 investments and TM6 a machine for 10 investments.

Three receiving switches are shown for receiving investment or transaction No. 1 at RAl, RBI and RC1. Outlets of receiving switch RAl are connected to keys KA-1 of ticket machines for 2s. 0d. investments. Outlets of switch R31 are connected to keys KBl of ticket machines for 1 investments and outlets of switch RC1 are connected to keys on ticket machines for 10 investments such as the one shown at KCl.

Registering switches for counting the number of investments received are shown at UAl, UB1 and U01, and are associated with receiving switches RAl, RBI and RC1 respectively. Addiand T31, and at T01 and TDl transfer circuits are represented which are connected from one registering switch to another registering switch direct.

These transfer circuits operate so that when ten investments of one denomination have been made one registration is effected on the registering device for the next higher denomination, leaving the apparatus associated with the lower denomination free to receive ten further investments for registration. A decimal system of investments is employed. Thus ten 2/ investments being equivalent to a single 1 investment cause. through the medium of a transfer circuit, a single registration on the apparatus adapted to receive and register 1 investments, and the apparatus for 2/- investments is left free to receive further investments. Separate transfer circuits, similar to one another, are used for each device for individual investments and also for the pool registering apparatus.

The apparatus for other transactions is similar to that required for No. 1, receiving switches RA2, BB2 and RC2 being connected to keys KA2, KB2 and KCZ respectively of the ticket machines for 2s. 0d.. 1 and 10 investments respectively. and receiving switches RA3, BB3 and RC3 (Figure 2) being similarly connected to keys KA3, K83 and K03.

Switches RTA, RTB and RTC are shown in Figure 1 for receiving the total pool of all investments made. Outlets from receiving switch RTA lead to ticket machines for 2s. 0d. investments. They do not terminate on keys but on a relay contact, not shown, which operates prior to the issue of a ticket by the ticket machine. Similarly, outlets from receiving switches RTB and RTC lead to ticket machines for 1 and 10 investments respectively.

Registering switches are shown at UTA, U'I'B and UTC which are associated with receiving switches RTA, RTB and RTC respectively, and additional registering switches at UTD and UTE for counting 100 and 1000 amounts.

Associated with each registering switch are remy groups GTA, G'IB, GTC, etc., and digit'display apparatus DTA, D'I'B, DTC, etc. Transfer circuits are represented at TTA, TTB, TTC and TTD.

It will be understood that a greater number of ticket machines and apparatus for more than three transactions and five denominations 0i investments may be provided. Also there may be a number of different displays for each transaction and for the total pool. These would be controlled by relay groups and registering switches the latter being, in turn, controlled by apparatus associated with the registering switches represented in Figures 1 and 2.

The detail of the circuit operations will now be described. In the circuit drawings relays and switches are referred to by capital letters which are placed on the drawings near their relative operating coils. Contacts are shown detached from their operating coils and are designated by small letters. The number of movable contacts possessed by each relay or switch is indicated under its designation, thus (Figure 7), denotes that relay YA has two movable contacts that are designated gal and 11112;

(Figure 7) .denotes that switch RTA has five movable contacts, one, an interrupter contact, is designated rtal, and others, which are wipers, are designated rta2, rta3, mm and 11:15. The source of electric supply is shown as a battery for the negative pole and as an earth for the other potential. The supply need not necessarily be a battery; it may, for example, be supplied from a generator.

In the following description it will be assumed by way of example, that an investment is made in a transaction specified by No. 1, but no different principle is involved if an investment is made on any other number. Further it will be assumed at first that all switches and relays are in the normal positions indicated by the drawings, and that 1,988,626 then a 2s. 0d. investment is made. The various circuit drawings should be arranged in the relative positions indicated by continuous lines in Figure 14 in which position it will be found that the switch designations tally with those on Figure 1. The dotted positions indicate alternative positions of certain figures when they are used in the description for difi'erent denominations.

The operator at a 2s. 0d. ticket machine operates a key, such as KA (Figure 3), thereby closing a circuit from earth, contact coal, relay CWA and resistance R1 in parallel, key KA, upper winding of relay LA to negative battery. The key remains mechanically locked in its operated position. Relay CWA does not receive sufficient current to operate in the above traced circuit; relay LA, however, does operate. Other windings of relay LA and windings of other similar relays are associated with diflerent ticket machines and with difierent outlets of the receiving switch.

The operation of relay LA closes at its contact Zal a circuit from negative battery, magnet 01 receiving switch RA, contacts m1, Zal, conductor 23, terminal 24 (Figure 4) to earth at contact cal. The receiving switch is of a well-known type used in automatic and semi-automatic telephony and having 25 outlets on each contact are or level. The receiving switches are connected in such a manner that their wipers have no home or normal position and it will be assumed that the switch is in the position shown before key KA is operated.

These receiving switches are of well-known type and have been fully described in U. S. patent specification No. 1,693,027.

The magnet of switch RA will operate in the previously traced circuit, and open its interrupting contact ml; the magnet then releases and in doing so moves the wipers forward to the next -bank contact. The release of contact ral again closes the magnet circuit.

This action is repeated and the wipers move round until an outlet is found which is connected to the operated key. All the outlets of switch RA are connected in a similar manner to the one shown, but they terminate on keys of different 2s. 0d. ticket machines. When wiper m2 reaches the outlet leading to the operated key, a circuit is closed from earth, contact coal, relay CWA in parallel with resistance R1, key KA, wiper m2, conductor 25, terminal 26 (Figure 4) relay CA to negative battery. Relay CWA still remains unoperated but relay CA operates and contact cal opens a point in the previously traced circuit of the magnet of switch RA thereby arresting its motion.

Contact cal also closes an obvious circuit for auxiliary relay CXA. Relay CXA operates and the magnet of registering switch UA energizes in an obvious circuit closed by contact cwal. This switch is in general similar in construction to receiving switch RA of the type described in U. S. patent specification No. 1,693,027 but it has fifty different positions. The various levels of 25 contacts are associated in pairs; thus wipers 11116 and um? are associated with one pair of levels the wipers being arranged at 180 to each other. The circuit arrangements are such that the switch has five normal or zero positions, that is, every tenth position is a normal position.

Contacts 0x02 and cxa3 close circuits for other registering switches, not shown, which control other displays when these are required. If the displays are some distance away it is preferable to provide a relay at each of the distant ends for controlling the circuit of the relative registering switches; contacts 0:412 and c103 are then arranged to close the circuit of these relays instead of directly closing the circuit of the registering switches.

Contact era-1 closes a circuit for relay SA from earth, contact 0x114, wiper ua4, terminal 27 conductor 28, terminal 29, relay SA to negative battery. Relay SA operates and at contact sa6 is held operated from negative battery, relay SA, contact sa6, terminal 30, conductor 31, terminal 32 (Figure 10), contact of homing key KH to earth. The homing key is common to a plurality of circuits and is left in the position shown when inventments are being accepted by the totalizer.

The operation of the magnet of switch UA at contact ualO shunts relay CA by a resistance, R2. This resistance is not low enough to cause the release of relay CA but the combined resistance 01' R2, relay CA and the winding of relay LA in parallel is low enough to allow suflicient current through relay CWA (Figure 3) at the ticket machine so that it will now operate. Contact cwal closes an obvious circuit for relay COA and ticket machine motor JA. Relay COA operates and at contact coal holds the circuit of the ticket machine motor closed so that it is independent of contact cwal. Contact coal also opens the circuit of relays CWA, LA and CA which release.

The relapse of contact cal (Figure 4) allows the receiving switch to be stepped to find another outlet should there be another investment awaiting acceptance; it also opens the circuit of relay CXA. Relay CXA. releases. and at contact czral opens the circuit of the magnet of registering switch UA. The latter then releases and moves its wipers forward one step in the direction of the arrows.

Relay COA (Figure 3) is locked in operation by way of its own contact and the ticket machine motor causes a ticket to be printed and issued. When the motor has nearly completed its operation it causes the operated key to be released and also causes cam CM to push back contact coal into its normal position. The circuits of relay COA and motor JA are thereby opened and the motor stops, also relay COA releases. These operations at the ticket machine do not form any part of the present invention but are given merely for explanatory reasons.

The relapse of contacts c:ca2 and cxa3 (Figure 4) causes the registering switch magnets controlling other displays to release and advance their wipers one step. The operation of the registering switches and digit display controlling relays for these displays is similar to the operation now being described so that the present description will serve both purposes. As it has been assumed that the investment being made is the first one on the particular transaction the registering switch UA will have moved from its normal or zero position into position No. 1. In this position a circuit is closed for relay A (Figure 5) from earth, contacts sal and sa2 in parallel, wiper 14416 in position No. 1, conductor 33, relay A to negative battery.

Relay A will be the only one of the digit display control relays A, B, C, D and E associated with conductors 33 to 37 inclusive, to be operated when switch UA is in its first oiT-normal position. This will result in

lamps

2, 3, 6, 10, l4, l7 and 21 glowing in circuitswhich are completed by way of conductor 38, contacts sad and sa5 (Figure 4) in parallel to earth. Thus the circuit of

lamps

2 and 3 is from negative battery by way of each of these lamps in parallel and contact c2 to the earth on conductor 38; the circuit of

lamps

6 and 14 is by way of contacts e2, a3, d1 and c3 to the earth on conductor 38; that of lamp 10 is by way of contacts c4 and e7; that of lamp 1'7 by way of contacts e6, d3, b8 and a7, and that of lamp 21 by way of contacts 06 and d7.

The various display lamps are arranged in a known manner such as shown in Figure 11, the numbered squares in Figure 11 correspond to the position of those lamps in Figure 5 bearing the same numbers. In Figure 12 the lamps that glow when the registering switch is in position No. 1 are shown shaded, their relative location being such as to represent the outline of numeral 1.

If other 2s. 0d. investment on the same transaction are made similar cycles of operations to the one described are completed; these result in the registering switch advancing its wipers one step for every 2s. 0d. invested in the particular transaction with which it is associated. According to the position of the registering switch, circuits for different combinations of relays A, B, C, D and E are completed, which result in different combinations of lamps being lit and these combinations form recognizable outlines of

numerals

0, 1, 2 to 9 inclusive. It is not thought necessary to trace out the circuits in detail in the case of each numeral. In Figure 13, however, a table is shown which gives the combinations of relays that are operated for different positions of the registering switches and the numbers of the lamps that are lighted corresponding to each combination. The resulting outline can then easily be discovered by referring to the position of the corresponding lamp numbers in Figure 11. The various combinations are repeated for every 10 steps of the registering switch so that for one complete revolution of the switch the equivalent of 50 positions is passed by the wipers and the connections to the combination relays are thus repeated five times. Iii-point switches could of course be used for the registering switches but the arrangement illustrated allows 25-point switches to be used, that have now become a well recognized standard in automatic telephone practice.

If a 1 investment be made the operation of the associated apparatus will be similar to that already described for a 2s. 0d. investment. If a 1 investment is received before a 2s. 0d. investment on any particular transaction it is necessary to ensure that the 2s. 0d. display reveals the numeral outline corresponding to 0. For this reason a contact, sa3, is provided which is connected to terminal 10 and from thence by conductor 39 to terminal 29 of the apparatus associated with the registering switch for 2s. 0d. investment. When the SA relay associated with the registering switch for 1 investment is operated, its contact, sa3, closes a circuit for the SA relay associated with the registering switch for 2s. 0d. investment. As the latter switch is in a normal position a circuit will be closed for relays A and E. According to the table in Figure 13 lamps will glow revealing the outline of numeral 0.

When nine 2s. 0d. investments have been received the associated registering switch will have made nine steps from one of its home positions, consequently when relays CXA (Figure 4) operates, as a result of a tenth investment, contact cra4 will close a circuit from earth, contact 02114, wiper M4 or 14:15, terminal 45, conductor 44, terminal 43 and relay T of the transfer equipment (Figure 9), to negative battery.

, Relay T operates prior to the movement of switch UA into a zero position and is held operated by way of its contact t1. Contact t2 closes a circuit for relay TR by way of conductor 41 and a winding of relay LB, (Figure 3), associated with the receiving switch for 1 investments. Relay LB operates and at its contact Zbl causes receiving switch RB to find an outlet that has been made common to conductor 41 the. subsequent operations being similar to those described in the case of switch RA. Relay TR does not receive sufiicient current to operate until the associated registering switch for 1 investments has been energised to close contact ualO (Figure 4). It then operates, the conditions being analogous-- to those described for relay CWA in the ticket machine for 2s. 0d. investments, and the registering switch for 1 investments advances one step and causes the associated display to be advanced accordingly. The effect on the digit display for 1 investments is, therefore, the same as if a 1 mvestment were made at the ticket machine. The operation of relay TR opens the locking circuit of relay T at contact trl; this causes the latter relay to release as its original operating circuit was broken when the registering switch for 2s. 0d. investments made its tenth step. As it is necessary to effect a transfer for each 10 steps of the registering switch terminal 45 (Figure 4) is made common to other outlets of the switch accordingly.

On referring to Figure 3 it will be seen that the transfer circuit is commoned to a number of outlets of the 1 receiving switch. This is done in order to ensure that a transfer is received by the 1 receiving switch before the 2s. 0d. registering switch has time to reach the next transfer outlet. The receiving switch may have to stop at other outlets before reaching one that is commoned to the transfer circuit.

In the drawings it will be seen that every fifth contact is connected to the transfer circuit. This allows investments to be received at a maximum rate by the switch of the lower denomination and yet it ensures that a transfer will be registered by the switch associated with the next denomination before the switch associated with the lower denomination can accept another ten investments for the next transfer. If the transfer were made direct to the registering apparatus there would be the danger that, if a transfer and an investment were required at the same time, they would not both be added to the relative display digit. The arrangements described ensure that each transfer is positively accepted without undue delay even if transfers are initiated simultaneously with investments from ticket machines. Further, simultaneous investments may be initiated on the same transaction from different ticket machines. Again, if a transfer or an investment is initiated at the moment a wiper of the receiving switch is passing over the associated contact, relay CA will either stop the switch at that contact and cause the investment to be registered and the ticket machine to operate, or, if it does not have time to do this, the receiving switch will step past the contact without affecting either the totalizing apparatus or the ticket machine. When, however, the receiving switch wiper again reaches that contact, or one commoned thereto as in the case of a transfer, relay CA will have a full opportunity of operating and will cause the investment to be registered.

The operation of the receiving switch and registering switch for 10 investments is similar to that described for lower denominations. If a 10 investment is received before a 1 or 2s. 0d. investment on the same transaction the SA relay associated with the registering switch for 10 investments closes a circuit for the SA relay for 1 investments which in turn closes a circuit for the SA relay for 2s. 0d. investments as previously described. This ensures that ciphers will be shown in both the 1 and 2s. 0d. digit displays. As for the purpose of this description it has been assumed that there are no ticket machines for a higher denomination than 10 investments, the transfer from the 10 regstering switch may be made directly to the registering switch for 100 amounts since there is no possibility of investment signals arriving from a ticket machine at the same time as a 100 transfer. Terminal 45 (Figure 4) of the apparatus associated with registering switches for 10 investments is therefore shown connected by dotted conductor 46, instead of by conductor 44, to terminal 47 (Figure 6).

When the first transfer is made to the 100 registering switch a circuit is closed from earth, contact cxa4 (Figure 4), wiper M4 or MS, terminal 45, dotted conductor 46, terminal 4'1 (Figure 6), and from thence in one branch by way of contact sd6 and relay SD to negative battery, and in another branch by way of dotted conductor 48, terminal 49, relay CD to negative bat tery. Relay CD operates and contact cdl closes the circuit for registering switch UD. Contacts cd2 and cd3 close circuits for registering switches for other displays. These switches operate, and upon the release of relay CD which follows the release of relay CXA in Figure 4, they make one step forward. Relay SD controls circuits for the indicator relays and lamps which are identical to those already described in relation to Figures 4 and 5. Terminal 53, however, which is connected to contact M3 and which corresponds to terminal 40 in Figure 4, is left disconnected as relay SD (Figure 6) will never be operated before relay SA. The locking circuit for relay SD is by way of contact sd6, terminal 51, conductor 50, terminal 32 (Figure 10), to the earth at key KH. Transfer circuit terminal 54 is connected by conductor 55 to terminal 4'? of the apparatus associated with the registering switch for 1000 denominations. The operation of the latter is identical to that of a 100 switch but terminal 54, relative to that denomination is left disconnected as it has been assumed for the purpose of this description that there are no other switches of a higher denomination.

The detailed description of the circuit oi. the pool totalizing apparatus will now follow; this circuit comes into operation when the CWA relay at a ticket machine operates.

It will first be assumed that a 2s. 0d. investment has been made, and that relay CWA has operated as previously described. Contact cwa2 at the 2s. 0d. ticket machine in Figure 3 then closes a circuit from earth, contact cwa2, conductor 56, relay YA (Figure 7), conductor 57, terminal 71 (Figure 8), relay P to negative battery. Relay 'P is made common to other relays similar to relay YA that are associated with outlets of the same totals receiving switch RTA which lead to different ticket machines, a separate P relay being preferably provided for, say, every ten YA relays. Switch RTA is substantially identical with receiving switches RA, RB and registering switches UA, U3 and a description thereof is to be found in U. S. patent specification No. 1,693,027. Relays YA and P operate, the former at contact 11112 closes a holding circuit for both relays and disconnects conductor 56. Contact yal marks an outlet of switch RTA.

Contacts p1 and :22 (Figure 8) close a circuit from earth, contacts pl and p2 in parallel, conductor 58, interrupting contact rtal (Figure 7), magnet of switch RTA to negative battery. The magnet operates, opens its own circuit at contact rtal, then releases and causes the wipers to be moved forward into the next position. This action is continued until wiper rta4 reaches the contact marked by contact yal.

Contact p3 closes a circuit from earth, contact p3, terminal 59, conductor 60, terminal 61, contact st6, relay ST to negative battery. Relay ST operates and is held operated by way of contact st6, terminal 62, conductor 63 to earth at key KH (Figure 10).

Relay ST (Figure 8) is identical with relay SA in Figure 4 and its operation results in the operation of an assembly of digit display relays and lamps identical with that shown in Figure 5, in the same way as describedin connection with relay SA. This separate display assembly indicates the pool total in the same way as the assembly associated with relay SA indicates the total relating to an individual transaction.

As soon as the receiving switch wiper encounters the earth applied by contact val this earth is extended by way of conductor 64, terminal 65 (Figure 8), relay CT to negative battery. Relay CT operates and at contact ct5 closes a circuit from earth, contact ct5, terminal 66, conductor 67, wiper rta2, relay XA to negative battery. Relay XA operates and at contact .ral opens the circuit of relay YA and the original operating circuit of relay P. Relay YA releases and relay P also releases if there is no other circuit completed by way of another relay similar to YA due to another investment awaiting acceptance. In the latter case the switch will continue to search for another marked outlet. 11' no other investments are awaiting acceptance contacts p1 and 102 open the driving circuit of switch RTA to prevent further movement of the switch. This prevents unnecessary wear of the switch. During the cycle of operations just described the switch will not have time to make more than one additional step. It will be noticed that relay XA (Figure '7) is connected to two successive contacts of the receiving switch. This'ensures that relay XA operates even if the additional step referred to is made by the switch. Contact gal opening removes the marking on the outlet of the receiving switch and the circuit of relay CT is therefore broken, whether the wiper remains on this contact or whether the switch steps to the next contact which, as Figure '1 indicates, has no wire connected thereto.

Relay CT- therefore releases and its contact 1 oil causes a momentary pulse to be given to register switch UT which thereby moves its wipers on to the next contact. This results in the digit display relays and lamps being operated-in a manner similar to that already described in relation to Figures 4 and 5. Contacts 0152 and ct3 close circuits for the apparatus for the distant displays. Contact ct4 controls the transfer circuit by way of wipers ut4 or ut5, terminal 68,

conductor 69, contacts yb2 and :cbl (Figure '7),

in the position for 1 investments) to the P relay of the registering switch associated with 1 pool totals to negative battery.

11, when relay XA operates, the earth on conductor 56 has not been removed at contact cwa2 (Figure 3), relay XA will be held operated by this earth by way of contacts rail, in its normal position, and (cal in its operated position. This arrangement prevents the possibility of a single momentary impulse causing a .double registration at the pool totalizing apparatus as no circuit can be closed for relays YA and P until relay XA releases. The release of relay XA takes place either when the earth on conductor 56 is removed, or, if the momentary earth has previously been removed, after the release of relay YA.

Relays X13 and YB, associated with the receiving switch for 1 pool totals are identical to relays XA and YA respectively associated with outlets to 2s. 0d. ticket machines. A transfer from the total pool registering switch for 2s. 0d. investments therefore causes the totals receiving and registering switches to operate in a similar manner to that described in the case of 2s. 0d. investments.

Other-outlets of the receiving switches for 1 totals are connected to other relays, similar to X13 and YB, associated with 020122 contacts (Figure 3) at different 1 ticket machines the connections and circuit operations being identical to the circuit shown and described for the 2s. 0d. ticket machines. a

The operation of the registering switch for 1 pool totals is also identical to the operation of the registering switch for 2s. 0d. pool totals. If a. 1 investment be received before 2. 2s. 0d. investment, the operation of relay ST (Figure 8) completes a circuit at contact st3 by way of terminal 72 and conductor '73 for the ST relay associated with the registering switch for 2s. 0d. pool totals. The 2s. 0d. total pool display iswthereby operated.

Transfers from the 1 pool totals registering switch are made to the 10 pool totals receiving switch in the same manner as described for the transfer of 2s. 0d. totals and the 10 receiving switches and the relative registering switches operate in a similar manner to those employed for 1 investments. Terminal 68 of the transfer circuit from the 10 pool totals registering switch is, however, connected by way of dotted conductor '74 to terminal 47 (Figure 6) of the registering switch for 100 amounts.

The equipment and the circuit operation for registering 100 and 1000 amounts for totals is identical to that described in the case of 100 and 1000 amounts for individual horses and it is not thought necessary to repeat this description.

At the conclusion of the proceedings the totalizer must be returned to normal in readiness for further or future operations. For this purpose key KH (Figure 10), is thrown thereby disconnecting all SA, SD and ST relays and completing an obvious circuit for relay H. The various SA, SD and ST relays release causing the display lamps to be extinguished and relay H operates and closes circuits for all registering switches controlling primary displays that are off their normal positions. In the case of a 2s. 0d. registering switch, for example, a circuit is closed from earth, contact hl, terminal 75, wiper mm or ua3, contact ual, magnet of switch UA to negative battery.

'relay YB, conductor 70, terminal '71 (Figure 8 The magnet operates and opens its interrupting contact ual thereby causing the wipers to be moved forward to the next position. This action is repeated until the switch returns to-anormal position where there is no connection to the magnet; further stepping is thus prevented.

Relay H has other similar contacts not shown which are connected to corresponding terminals on other registering switches. These terminals are designated 76 and 77 on Figures 6 and 8 re- 3 spectively. When there are a large number of transactions involved it is preferable to provide several relays similar to relay H. These may be all controlled by key KH which may be provided with additional contacts if necessary. The registering switches controlling distant displays are returned to normal in a similar manner by a relay identical to relay H which is operated by additional contacts on key KH not shown.

When it is desired to make different classes of investments the arrangements described are duplicated for each class except key KH and relay H which may, if desired, be made common to the apparatus provided for each class.

While in the foregoing description the apparatus is referred to as employed for the purpose of totalizing the number of sales or the number of investments made or similar transactions, it must be understood that it may also be used for many other less serious purposes and is not limited solely to those applications above referred to. For example, it may be used for amusement purposes, at all kinds of race and like meetings where it is desired to register investments made by the public upon various events in the programme, and such use must be understood to fall within the scope of the invention herein described.

I claim:

1. A transfer circuit arrangement for a totalizer comprising one relay adapted to operate fully prior to the movement of a registering switch into a zero position and to mark an outlet of a collecting switch associated with the next denomination, and a second relay adapted to .cause the release of the first relay after the collecting switch has found the marked outlet.

2. A transfer circuit arrangement for a totalizer comprising one relay adapted to operate fully prior to the movement of a registering switch into a zero position and to mark an outlet of a collecting switch associated with the next denomination, and a second relay connected in series with the conductor marked by the first relay and adapted to cause the release of the first relay after the collecting switch has found the marked outlet.

3. A transfer circuit arrangement for a totalizer comprising one relay adapted to operate fully prior to the movement of a registering switch into a zero position and to mark an outlet of a collecting switch associated with the next denomina tion, a second relay adapted to cause the release of the first relay after the collecting switch has found the marked outlet, and means whereby all the totals received by the registering device of the higher denomination from that of the lower denomination are registered even when the device of the higher denomination is registering for another or a plurality of other sources.
