Patent GB-426391-A (GB)
Abstract: 426,391. Ticket - issuing machines. BELL PUNCH CO., Ltd., 39, St. James's Street, London. June 30, 1933, No. 5693/35. Convention date, April 10, 1933. Divided out of 426,326 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 1, 1934. [Class 106 (iii)] In ticket-issuing machines as described in Specification 426,326, in which a strip is led between printing and feeding rollers so as to issue a pre-determined number of tickets according to the key selected for operation, the strip of tickets being then cut off, each key is associated with rotary stops of different dimensions whereby a toothed quadrant is moved through an angle corresponding to the key which is depressed. The strip 1 is led upwards between rollers connected by gears 2, 3 operated by an electromotor through the gear 4, one ticket being printed for each revolution of the rollers, the strip of tickets then being cut off or perforated by cooperating knives or perforators one carried by each roller and operative along their common normal. Keys 6, one for each number of tickets to be issued together, are mounted on a spindle 8, each key having an extension 52 which co-operates with a corresponding selector 46 mounted upon a shaft 47. When any key 6 is depressed, for example the key which issues two tickets, an arm 11 with a cross piece 12 common to all the keys, lifts link 13 and pawl 17 so that the toothed quadrant 21 may move in an anti-clockwise direction. The extent of movement of the quadrant is controlled by a rack connection 41 to a toothed sector 42 which is rotated by a spring-controlled pin 44 through an angle which is limited by the engagement of the shoulder 51 on the appropriate selector 46 with the extension 52 on the key which has been operated. The first part of the movement of the quadrant 21 closes the starting switch 39 for the electromotor by means of a pin 24 on the lever 23, 32 and the lever 34, 36. At the same time, the lever 28 (which is normally held up by a stiff spring 29) is lowered by a shoulder on lever 23, 32 engaging pin 27, so that pin 55 carried by the toothed wheel 4 is freed. A lateral extension 31 on lever 28 also frees lever 53 by which gear wheel 4 is clutched to and driven from gearing connected to the electromotor. Towards the end of one revolution, roller 58 on the gear wheel 4 operates lever 59 and pawl 61 so as to return quadrant 21 in a clockwise direction through one tooth. It is retained in this position by pawl 17, previously freed from the end of lever 13 by link 72 operated from a cam 71 on one of the printing and feeding rollers. This completes the feeding and printing of one ticket and the operation is repeated until quadrant 21 is returned to its rest or extreme clockwise position when pin 24 is engaged with the result that the switch 39 is opened. The overrun of the motor is sufficient to complete the last cycle and the cutting operation, the parts being brought finally to their rest position by pin 55 on gearwheel 4 snapping into recess in lever 28 and by extension 31 on lever 28 disengaging driving pawl 53. The cut off ticket or strip of tickets is fed out by delivery rollers 66 78 operated by a cam on one of the main printing rollers. The keys which are not in operation are locked in their raised position by engagement of their projections 52 with the underside of the part carrying the stop 51.
