Patent GB-384001-A (GB)
Abstract: 384,001. Totalizators; display arrangements. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and LIMB, F., Holmwood, Fellows Road, Beeston, Notting- ham. Sept. 10, 1931, No. 25356. [Class 106 (i).] To reduce the amount of display apparatus in a totalizator the number of characters displayed simultaneously is made substantially less than that required to give a complete indication of the actual or relative amounts invested on each of all the competitors in an event. For example, information regarding each of a plurality of competitors such as the totals or odds thereon may be displayed successively in the same display space, or information regarding win and place bets may be displayed successively in the same display space. Alternatively the competitor numbers or other characters indicative thereof may be displayed in order of betting popularity. Numerous modifications are described. The indicators are preferably of the monogrammic type but may be of any other suitable kind. In the embodiment according to Fig. 1, the totals on nine competitors, both win and place, are displayed in turn on an indicator CT by means of a sequence switch SS stepped under the control of contacts X, periodically operated in any convenient manner. Consecutive odd and even contacts of banks ss6 .. ss10 are connected respectively by way of relay contacts to the wipers of the various competitor win and place registering switches. Thus lines 11 from these banks lead by way of contacts sa, ob, oc, od, oe, to wipers a (units), b (tens), c (hundreds), .., e (tens of thousands) respectively, of the win registering switch of a competitor equipment EB ; lines 12 lead to the corresponding wipers of the place registering switch of equipment EB. (Contacts sa, ob .. oe operate when their respective denominational registers first move off zero and serve to prevent the display of reduntant zeros.) The banks a .. e are connected to the corresponding denominational elements u, t, h, th, tth of the indicator CT and are multipled to the corresponding registering switch banks, both win and place, of all the other competitors. Associated with competitor equipments as EB or EA are plugs PB, PA the upper four contacts of which are connected to appropriate consecutive contacts in banks ss2, ss3, ss4 the lower three leading to registering controls RB, RA. These plugs may be inserted in any competitor jack J1, J3 .. J20, connected to ticket machines TMA, TMB, TMC and to the units, uc, and tens, tc, elements of the competitor number indicator CN. In operation, the plugs PA, PB, .. having been inserted in appropriate jacks J1 .. J20, a start key is thrown to operate a relay BS. At bs1 a relay Q is energized and interacts with drive magnet ss to step sequence switch until wiper ss2 reaches a contact marked over bs2 the relay Q being thereby short-circuited. Assuming plug PA is inserted in jack J13, switch SS will be stopped in position 1 and at bs3 circuits will be made over wipers ss6 .. ss10 by way of the competitor register EA to the totals indicator CT, and over wipers ss3, ss4, terminals 3, 10, the elements uc and tc will be energized to display the competitor number 13. Over bs4 and col the indicator WP will energize to display W for win. At the next actuation of contacts X, the sequence switch advances one step whereupon the earth at contacts bs3 is connected over ss6 .. ss10 to the place register of competitor numbered 13, the total thereon being now displayed at CT. The same competitor number is displayed at CN but a relay CO energized over the even (place) contacts of wiper ss5 changes the WP display to place at contacts co1. In subsequent positions of SS the totals, win and place, on the other competitors are similarly displayed. Contacts np1, np2 are operated when place betting is not allowed. Some of the contacts of bank ss2, for example one to six, are multipled to thirteen to eighteen. The three competitors who are likely to be favourites are plugged in to these positions, their totals being thereby displayed twice as often as those of the remaining competitors. Alternatively the figures pertaining to the favourites may be displayed for longer periods by manual or automatic control of contacts X. A pool total indicator AT is provided and may be adapted to display both win and place pools under the control of further contacts of relay CO. By providing two sequence switches and CT indicators, win and place bets could be shown concurrently. In the embodiment according to Fig. 2, there are individual competitor total indicators CT1, CT2, .. and corresponding competitor number indicators CN1, CN2, ... Each competitor denominational win register wa, units, wb, tens, .. we is paralleled with the place register pa, units, pb, tens, .. pe. Normally the win totals are displayed over contacts cox1 .. cox5, and contacts wsa, wob .. woe (correspondingly to sa, ob .. oe of Fig. 1), the place totals being displayed by periodically operating contacts X1 to operate the change over relay COB, contacts of which, as cob2, operate the COX relays of all the competitor registers. Contacts cob1 control the display of the W, win, P, place indication. In the embodiment according to Fig. 3, the competitor numbers are displayed in order of betting popularity on a vertical column of indicators CN1, CN2, CN3 .. CN24, CN25, the totals of only the first and last competitors being displayed. Associated with each indicator is a switch DS having two wipers ds1, ds2 which are manually set to indicate on tc1, (tens), and uc1, (units), the digits of the appropriate competitor number on closure of a key DK, the order of the numbers being changed as desired during betting. The first and last DS switches corresponding to indicators CN1 and CN25 have further banks ds3 .. ds7, to which are connected seriatim, the wires from competitor jacks J<1>1, J12, .., the first five wires leading to the DS switch of CN1 and the last five to the DS switch of CN25. A multipoint jack PAl, PB<1>, .., is associated with each registering switch, all of which have banks as aa1, ab1 .. ae1 multipled to the corresponding denominational sections u1, t1, .. of indicator CTD1, and corresponding banks aa2, ab2, .. ae2, similarly multipled to the sections u25, t25 .. of indicator CTD25 The jacks J<1>1, .. of the competitors who it is assumed will be first and last as regards betting popularity, are inserted in their respective jacks PA<1>, PB<1>, .. and the DS switches corresponding to indicators CN1 and CN25 are set to the appropriate positions and keys DK thrown, the indicators CTD1 and CTD25 then displaying the totals invested on these competitors respectively. If the number of competitors is less than the number of indicators CN1 .. CN25, the former may be given positions in the vertical column corresponding approximately with the relative totals thereon. In a modification one DS switch and indicator CN1 only may be provided, the competitor numbers being displayed successively in their order of betting popularity thereby.
