Abstract: 490,671. Ticket printing and issuing machines. CLAYTON DEWANDRE CO., Ltd., and HARRIS, W. P. Jan. 18, 1937, No. 1484. [Class 106 (iii)] A ticket printing and issuing machine as set out in Specification 397,889 is provided with means for printing two denominational tickets by successive printings by the same adjustable printing element, the ticket strip severing device being rendered temporarily inoperative by the printing of a value in the larger denomination. When printing in a larger denomination is required the lever 11 for setting the class printing wheel 2a is moved to its extreme position against the stop 51, the lever 53 being moved against the action of the spring 54 to pass over the stop 52. This movement of the lever 11 causes a cam 30 on a toothed sector 12 on the lever 11 to become disengaged from a pin 29 on an arm 28 mounted on a rock shaft 27 on which are mounted arms 25 engaging pins 26 on a slidably mounted counter carrying plate 15 which is thus moved upwards by the spring 24 to disengage the smaller value counter 17 from and engage the larger value counter 18 with the spur wheel 21 driven from the setting shaft 23 of the value printing wheel 2b. A pin 33 on the plate 15 is also moved upwards to allow movement of the bell-crank lever 32, link 34 and lever 35 under the action of the spring 36 to move the pawl 37, pivoted on the casing of the machine, to a position in the path of movement of the spring controlled rocking lever 31 operatively connected at one end to the ticket strip guillotine and actuated as described in Specification 397,889. With this position of the pawl 37 the downward movement of the lever 31 during printing pushes the pawl 37 aside which then returns so that upward movement of the lever 31 to actuate the guillotine is prevented during the strip issuing movement of the machine. Resetting of the machine to print in the smaller denomination causes movement of the lever 35 but the pawl 37 remains in frictional contact with lever 31 and only returns to inoperative position when lever 31 is depressed at the next printing stroke. The class printing wheel 2a is fast on the hollow shaft 10 and is set by the lever 11 through the toothed sector 12 and toothed wheel 13 also fast on the shaft 10. The wheel 2a has a slot 9 coaxial over the greater part of its length but offset at one end and engaging with an arm 8 on a die 6 pivoted on a pin 6c within a slot in the die plate 3 adjacent the value printing wheel 2b, and having two printing faces 7a, 7b for pence and shillings, the " shillings " face being positioned in the printing position when the class printing wheel 2a is moved to its extreme position by the lever 11 to cause the arm 8 to be moved into the offset end of the slot 9. The wheel 2a may have a die 6a to print a symbol to indicate that the ticket is two-denominational when the wheel is in its extreme position. The lever 11 can be held in adjusted position by the finger operated spring controlled pawl 13a engaging the notched sector 14. Means are provided for locking the lever 11 when a printing operation in the shilling denomination commences and releasing it only when the value printing wheel zeroizes, comprising a spring controlled lever 47 having an-offset end engaging behind a shoulder 12a on the sector 12 and a lever 48 pivotally mounted on the lever 47 and extending into the path of a pin 46 carried by the feed ratchet 55 fixed on the value printing wheel shaft 23. A " total tickets issued " counter 56 is actuated from the lever 31 through a bar 39 attached to a rotatable plate 40 carrying a spring pressed pawl 42 engaging a ratchet wheel 43 fast on a spindle 41 secured to a bevel wheel 44 driving a bevel wheel 45 on the spindle of the counter 56. Serial-number printing and registering mechanism may be incorporated in the machine.
