Patent GB-376390-A (GB)
Abstract: 376,390. Ticket-printing apparatus. PARKER, A. R., 32, Devonshire Place, and SOUTHDOWN MOTOR SERVICES, Ltd., Steine Street, both in Brighton. April 17, 1931, No. 11390. [Classes 100 (ii) and 100 (iv).] Time-printing apparatus for ticket punches.- The trip-released hammers 75, 76 force the ticket on to the inking ribbons 48, 49 above the hour and minute impression discs 30, 31, 32 and the day and month impression discs 21, 22, 23 respectively. The discs 21, 22, 23 are independently revoluble on a common spindle 24 mounted between the cheeks of a detachable frame 25 which is mounted in a bracket 26 carried on the underside of the ticket platform 5 and may be readily removed when the casing is opened for the purpose of manually resetting the discs. The frame 25 is held in the bracket 26 by means of a locking plate 29. The discs 21, 22, 23 are retained in their adjusted positions by spring-controlled detents 27 which engage with ratchet wheels 28 associated with the discs. The hours impression disc 30, the " tens " minutes impression disc 31 and the " digits " minutes impression disc 32 are actuated from clock mechanism through the associated ratchet wheels 42, 43, 44 having gaps 45, 46 and operated by the pawls 36, 37,38 arranged on a pivoted plate 35 carried by a spring-controlled U-shaped cradle 33 and adapted to be swung downwardly through a connecting rod 40 actuated through the pins 411, 412 on the crank 41 rotated from the clockwork mechanism through the final drive spindle 410. The clock mechanism which is provided with the customary winding arbor 105 and spring-controlled pawl and ratchet mechanism 106 can be stopped by plate 103 slidable along the face of the cover-plate 104 of the clock mechanism to move into the path of rotation of the crank 41. To facilitate resetting, the discs 30, 31, 32 are accessible through openings 120, 121, 122, but to prevent unauthorized tampering the discs are rendered inaccessible so long as the casing is closed by means of a sliding gate 123 accommodated between the back wall 124 of the easing and the baseplate 1. Upward and downward movements of the gate 123 are normally prevented by contact of the gate with the casing and with a stop 125 provided on the baseplate 1. Ink-ribbon, mechanism.-The inking ribbons 48, 49 for the discs, Fig. 10, are wound around a pair of duplex spools 50, 51 selectively rotated by spring-controlled pivoted pawls 61, 62 mounted on a slidable T-shaped carrier 63 vertically reciprocated by means of a pin 66 on the carrier engaging the lever 65, the outer end of which engages beneath a bridge-piece 67 carried by the operating slide 3, the opening in the bridge-piece permitting of an initial movement of the slide 3 before movement is imparted to the lever 65 and the pawl carrier 63. Reversing mechanism for the pawls 61, 62 comprises rockers 68, 69 having fingers 72, 71 engaged by projections 75 near the ends of the ribbons to move one pawl out of driving position and move the other one into driving position. The shell 128 of the apparatus is locked during use to the cover-plate 104 of the clockwork by means of a staple 130 thereon, with which engages the bolt of the key-operated lock 131. When the shell 128 is closed the lock 131 contacts with the ribbon spools 50, 51 to maintain them in position.
