Patent GB-756253-A (GB)
Abstract: 756,253. Selective printing. WESTING- HOUSE GARRARD TICKET MACHINES, Ltd., and DAVIES, J. E. June 32, 1955 [June 23, 1954], No. 18440/54. Class 100 (4). [Also in Group XIX] In ticket issuing machine comprising a group of cash levers the operation of,which conditions the machine for printing a cash value and one or more ledger levers the operation of which conditions the machine for printing a distinguishing mark on the ticket, interlocking means are provided for preventing the operation of both the cash and ledger levers so that the cash totalizer mechanism is not operated by a ledger transaction. As applied to a machine with two ledger levers 5, 14, the lever 5 having one operative position K and the lever 14 several operative positions, the lever 5 is provided with a projection 10 which as the lever moves to its operative position engages an arm 12 of a pawl 6 to turn the pawl against its spring 9 into a position where its other arm engages projections 13 on the cash levers 1 to prevent their operation. Alternatively if a cash lever 1 is already operated the projection 13 prevents the pawl 6 from turning so that the lever 5 cannot move into its operative position. The second ledger lever 14 is locked in its inoperative position by means of a hooked arm 16 fixed to the pawl which engages a projection 15 on the lever 14. Consequently when the lever 5 is set to print the common ledger label, the lever 14 may be set to print the ledger numeral. The curved periphery of the projection 15 prevents the pawl 6 from returning under its spring even if lever 5 is returned to its inoperative position so that the cash levers 1 cannot be operated until both ledger levers 5, 14 are inoperative.
