Abstract: 332,942. Black, H. D., and Webb, C. F. April 25, 1929. Totalizators. - A ticket printing, issuing, and registering machine for use in connection with horse racing comprises a series of keys for selecting one of a series of types, a member for selecting one of at least two further types and registering means associated solely with the two selected types. The keys 1 select a printing type of a series corresponding to the horses running, carried by the printing cylinder 2 in the manner set forth in Specification 325,873, [Class 106 (iii), Fares &c.]. The member 4 is slidable to two positions, firstly to move one of the " win " or " place" type faces 5a, 5b, of the member 5 into the printing surface of the cylinder 2 through the link 8 and rod 9, secondly to rotate the insulated conducting disc 22 to one of two positions through the pin 20 on the arm 21 secured to the disc 22, to select the " win " or " place " circuit of the registering mechanism corresponding to the selected horse in the manner set out below, and thirdly by means of the cam face 43 and roller 42 to move a selector member 36 to one or other of two portions to set for operation the counter 31 registering the total number of tickets issued, and either the counter 29 registering " win " tickets issued or counter 30 registering" place " tickets issued. A test key 1<1> is connected by means of a link 44 to the selector member 36 so that operation of the test key moves the member 36 to such a position that none of the counters are actuated. To prevent operation whilst the type member 5 is being set the full width of the member 4 maintains the gate 7 closed during its movement whilst depressions 47 in it allow, when it is in operative position, the depression of only one key at a time. The disci 22 has contact bars 24, 25 which extend on either side of two banks of contact blades 26 and 27 mounted upon an insulating carrier 28. A pair of contact blades 26, 27 corresponds to each key 1, and a disc 48 of insulating material. A contact bush 25a bears against the disc 22 and is connected to the electrical registering mechanism. Depression of a key causes the disc 48 to bend the blades 26, 27 causing contact between the blade 26 and rod 24, or between blade 27 and rod 25, according to the position of the member 4, thus completing the circuit to actuate the corresponding " win " or " place " registering mechanism 56 or 57. The " win " or "place'" mechanisms of the keys, are, controlled by switches 60 at a central station so that in the case of a non-runner the corresponding switch 60 is opened thus breaking the circuit through the registering mechanism and the electro-magnetic release device 49 for the machine, and preventing the machine from operation. The operation of the electrical registering mechanism is similar to that described in Specification 330,264. Fig. 13 shows. the arrangement for two ticket issuing machines A. Fig. 14 shows a method of connecting elec-. trically two ticket printing and issuing machines to a central control station by means of coding and decoding mechanism E, F. In this arrangement the selective contact disc 22 is dispensed with and depression of a key causes one blade,. e.g. 26, to contact with the bar 24, and movement of the member 4 to the " place '' position closes a " place " switch 53. The coding device E can be arranged to ensure that the electro-magnet 49 controlling the starting of the ticket machine by means of a relay is excited only when the impulse generated by the key contact has initiated the corresponding impulses in the coding lines 63, so that the starting of the ticket machine shall be dependent upon the initiation of impulses to the distant decoding device.
