Abstract: 893,794. Ticket-issuing machines. BELL PUNCH CO. Ltd. Aug. 15, 1958 [Aug. 27, 1957], No. 27029/57. Class 106 (3). Ticket printing is effected by manual depression of a lever 10 against the force of spring 13, the return movement of the lever feeding the ticket past the issue aperture and partially severing it. Single length ticket issue; ticket counting.-In order to issue a single length ticket, lever 10 is pressed downwards until members 173, 171 abut. Pin 20 on lever 10 raises a lever 21 and through a link 30, advances the number recorded on a numerator (counter) 34 by unity. Setting the guillotine.-At the same time, the toothed segment 12 rotates the segment 40 anticlockwise. A peg 56 on segment 40 is thus moved downwards (Fig. 2), engages a pawl 132 and thereby rocks the pawl carrier 130 clockwise about axis 121. A movable knife 115 which is pinned to the pawl carrier 130 is thus moved downwards against the force of a spring 144, until locked by a lug 136 on a pawl 131, pivoted to the carrier plate 130, engaging a notch 125 in a latchplate 124. The top of the movable knife 115 is then clear of the (fixed knife) upper edge of an aperture 111 in a plate 112. Setting the ticket advancing mechanism.-The anticlockwise rotation of member 40 rotates a gear-wheel 80 (Figs. 1 and 4) through 120 degrees together with a ratchet-wheel 81 with three ratchet teeth. Printing.-At the same time, a pawl 48 on member 40 engages roller 168 and raises lever 166 which carries a platen, between which and the type wheels 153, 154 the ticket and carbon paper are pressed, the printing wheels having been previously manually set in known manner. Advancing the ticket.-When the lever 10 is released, the member 40 rotates clockwise under the influence of springs 13 and 42. A pin-wheel 88 whose pins 89 engage holes in the ticket strip to be advanced, has mounted on it a pawl 95, spring urged to engage a tooth of ratchet-wheel 81, so that when the rotation of member 40 causes gear-wheel 80 to rotate in an anticlockwise direction, the ticket strip is advanced by the length of one ticket and is fed through aperture 111. Ticket partial severance.-Pin 56 rises and towards the end of its upward movement engages pawl 131 to release it from the latch plate notch 125, so that the knive 115 moves sharply upwards under the influence of spring 144 partially to sever the ticket. Partial severing of the ticket is achieved by appropriate shaping of the knife 115 as at 118. Double length ticket issue.-In order to issue a double length ticket, member 173 is first rotated by means of lever 174 so that it clears abutment 171 and permits depression of lever 10 to the bottom of casing slot 70. Pin 20 then moves along to the end of the cranked portion of lever 21, causing the number shown on the numerator 34 to be advanced by two units. The gear 80 is rotated by 240 degrees, so that on release of the lever 10 a double length ticket is advanced. The increased rotation of segment 40 causes a pawl 46 to engage a roller 169 on lever 165 and raise a corresponding platen to cancel the serial number of the second ticket on a cancelling type bar 160. The severing mechanism is actuated as before. Specification 568,805 is referred to.
