Abstract: 695,544. Coin freed machines delivering tickets cut from strip. BELL PUNCH CO., Ltd. Aug. 31, 1949 [May 24, 1949]. No. 22638/49. Class 27. [Also in Group XIX] Delivery of tickets cut from strip; construction of the strip feeding and cutting mechanisms. When.a yoke 110, 182 (Fig. 6) is oscillated a pawl 124 on it drives, a ratchet wheel 142 integral with a pinwheel 148 which feeds a ticket strip from which a ticket is cut by a blade 116 carried by the yoke 110, 182 and co-operating with a fixed blade 120. The fixed blade 120 comprises a leaf spring which is flexed aside by a cam-like extension 118 of the moving blade 116 as it rises. The ratchet wheel 142 is normally held against rotation in the feeding direction by a detent 132 which is withdrawn when a pin 140 on the driving pawl 124 engages a flange 138 on the pawl 132 to turn it about its pivot 128 against a spring 136 which also biases a further detent 134 preventing reverse rotation of the ratchet wheel. On continued rotation of the yoke 110, 182 and the pawl 126 the flange 138 passes under the pin 140 and the pawl 132 is released to engage first the crown of a tooth 146 of the ratchet wheel and then the periphery of the ratchet wheel: the rotation of the ratchet wheel and the pin wheel is thus limited to the pitch of the teeth 146. On the return stroke of the pawl 124 the pin 140 is cammed beneath the, flange 138. The pins of the pinwheel pass through slots in a guide 150 and a cover 152 to engage perforations in the ticket strip and feed it between the guide and the cover to the knife blades. The cover 152 is hinged at 153 and held in position by a spring 158. Delivery of tickets cut from strip (cont.); driving the strip feeding and cutting mechanisms. In the manually operated machine shown in Fig. 3 a lever 16 pivoted at 46 is connected by a rack bar 54 and a pinion 58 to turn a coin freed shaft 30 first clockwise and then anticlockwise as the lever 16 is depressed by its handle 14 and 'returned by a spring 48. During the clockwise movement of the shaft 30 a cam 92 thereon engages a roller 94 on a bell crank 98 pivoted at 100 to a disc 102 which is thereby rotated about the shaft 114. Continued 'clockwise movement of the cam 92 carries it beneath the roller 94 so that the bell crank 98 and the disc 102 are returned by a spring 104 which also serves to urge the bell crank against a guiding roller 99. A slot 106 in the disc 102 imparts the resulting oscillating motion to the pin 108 by which the pawl 124 (Fig. 6) operating the strip feeding mechanism is mounted on the yoke 110, 182. Should friction prevent the bell crank 98 and disc 102 from completing their return movement they are returned by the anti-clockwise movement of the cam 92 which, after pushing aside the roller 94, engages a pin 96 on the bell crank 98. In a power operated machine the cam 92 and shaft 30 may be rotated through a single complete revolution by an electric motor each time the machine is operated. The motor is started by momentarily closing the coin freed circuit. of a solenoid which withdraws a detent from a notch in a cam which is then turned by a spring to close a switch in the motor circuit; it is stopped when the cam 92 as it approaches its starting position engages a pin on the switch-operating cam to return it to open the motor switch and permit re-engagement of the detent. ' Counting tickets issued. A link 178 (Fig. 6) connects the yoke 110, 182 supporting the moving blade of the knife to a counter 174 (Fig. 1). Alarms and indicators. A bell is struck each time the machine is operated. As shown in Fig. 3 the hammer 64, 66 is pivoted at 68 and normally held out of engagement with the bell 62 by engagement along a flat surface 70 with alever 72 biased about its pivot 74 by a spring 76. A weaker spring 84 urges a strut 80 pivoted at 82 to the hammer 66 against a stop 86. As the lever 16 is depressed a pin 90 on it engaging the flat upper end of the strut 80 depresses the strut so withdrawing the hammer 64, 66 from the bell and camming aside the lever 72 against the action of the spring 76. On continued downward movement of the lever 16 the pin 90 escapes from the strut 80 so that the spring 76 returns the lever 72 and the hammer 64, 66 and the latter overruns to strike the bell. Coin action, thrust; coin moved by rotary member to disengage detent therefrom. A pawl 36 (Fig. 1) limits rotation of the shaft 30 unless it is pushed aside by a coin in a pocket C in a member 32 on the shaft. Coin testing means 26 and a full stroke pawl and ratchet mechanism 38, 40 are provided. Insertion of coin in empty and faulty apparatus, preventing. A member 160 (Fig. 6) pivoted at 162 and bearing against the ticket strip carries a flang 164 which engages a crank 166 (Fig. 1) on a shaft 168 to prevent this shaft from being turned by a spring 172. In the absence of a ticket strip the shaft 168 is turned by the spring to obstruct the coin slot at 170. A lever 171 may be moved manually by its end 173 to obstruct the slot
