Abstract: 697,281. Totalizators ; ticket-printing machines. BROWNE, J. N., and HANDLEY, J. April 11, 1950 [Jan. 21, 1949], No. 1727/49. Classes 106 (i) and 106 (iii). An automatic ticket validating machine for use in a totalizator system comprises means for sensing the significance of perforations in a ticket which is inserted into the machine in order to register a bet, means for transmitting a bet signal to the totalizator, means for receiving a checking signal from the totalizator, and means for printing particulars of the bet on the ticket so as to provide the bettor with a record of the registered bet. The ticket 1 is inserted into the machine as shown in Fig. 3 and rocks an arm 2 to close contacts 3, whereupon a solenoid 4, Fig. 4, is energized to move a carriage 5 downwards so that pins 6 sense holes 7, Fig. 5, at the end of the ticket. The pins 6 co-operate electrically with stationary pins 8 and the circuit arrangement is such that if the holes 7 in the inserted ticket are of the correct number and location a relay 8<SP>1</SP> is operated when the contacts 9 are closed by depression of the desired competitor key 10, Fig. 3. The " price " obtained for each competitor is being continuously registered on a selector type switch 55, Fig. 6, and is printed on the inserted ticket by a printing wheel 14, Fig. 3, set as described later. When the relay 8<SP>1</SP> is energized the contacts 45-49, Fig. 6, are closed and one or more of the relays 19-23 are energized in accordance with the position of the selector switch 55. The relays 19-23 control escapements 13, Fig. 4, which determine the extent of rotation of a differential train 18 which is urged to rotate by a rack 16 acted on by a spring 17, Fig. 3, and which is connected to the " price printing wheel 14 through gearing. As soon as each escapement 19-23 completes its movement the corresponding make contacts 45<SP>1</SP>-49<SP>1</SP> and break contacts 50<SP>1</SP>-34, Fig. 6, are actuated to establish a circuit through a relay 71<SP>1</SP> to an assigner in the control apparatus, not shown, whereby the relay 71<SP>1</SP> operates to close a contact 72, whereby a relay 72<SP>1</SP> in the adding mechanism is operated and closes contacts 61<SP>1</SP>-65<SP>1</SP> and contacts 66<SP>1</SP>-70<SP>1</SP> so that the appropriate relays 61-66 are actuated. A circuit is therefore established from earth and contacts 72, 66-70 to register the bet on the adding magnets in the control apparatus (not shown) which subsequently sends a release signal to operate relay 73 which operates a solenoid 27, Fig. 3, of the ticket printing machine, the platen 28 of which is reciprocated to print on the inserted ticket from the " price " wheel 14 positioned as described above and from the competitor number wheel 24 and race number wheel (not shown) positioned as described in Specification 591,260. At the same time a guillotine blade 30 is operated to sever the end of the ticket along the line X-Y, Fig. 1, so that it cannot be used again. Upon return of the platen 28, Fig. 3, the rack 16 is moved downwards to restore the differential train 18 and the wheel 14 to their initial positions.
