Abstract: 1304351 Fare-collecting boxes; issuing tickets BELL PUNCH CO Ltd 3 June 1970 [3 June 1969] 28042/69 Headings G4T and G4X A cash box, which may be part of a ticketissuing apparatus, comprises a shoot, a stop 5 in the shoot which retains the coins and a window 3 enabling the coins to be viewed. If the value of the coins equals the price of the ticket solenoid 13 is energized to withdraw plunger 12, breaking the toggle formed by pivoted arms 7, 8 and swinging plate 4 forming the back of the shoot away from window 3, thereby releasing the coins, which are deflected by guides 14, 15 into a retaining box. Spring 11 then restores the toggle. When the cash box is incorporated into a one-man bus solenoid 13 is operated by a ticket issuing machine (Fig. 3). The driver presses the key 29 corresponding to the fare required, thereby switching off transistor 30 and hence relay C, and causing the corresponding thyristor 31 to conduct, thereby completing a circuit through the corresponding diode 35 to energize relay E. The consequent closure of switch RLE2 energizes flip-flop oscillator 24, whose pulses are amplified at 25 to operate solenoid 43, to step forwards both the price printing wheel and the rotor arm 32. When arm 32 meets the contact which is in series with the conducting thyristor relay A is energized so that solenoid 43 is disconnected and ticketissuing solenoid 44 energized by movement of switches RLA1 and RLA2. The closure of RLA3 operates coin-collecting solenoid 13 and phosphor counter 33 whilst closure of RLA4 de-energizes relay B and hence, through opening of RLB4, de-energizes relay D. This opens RLD2 to switch off flip-flop 24, and moves RLD4 to de-energize relays A and E, thereby closing switch RLE3 to light coin viewer lamp 100 to indicate that another cycle may commence. The fare stage at which each ticket is purchased is printed on the ticket by type-wheels stepped forwards by solenoids 41, 42 under the control of the apparatus of Fig. 4. Wafer switches 130, 131 represent the units and tens of the fare stage number, and the upper arm of one or both switches are adjusted by the driver as each fare stage is reached. The resulting deenergization of relay 138 and or relay 147 lights lamp 132 to warn the driver to operate switch 133, thereby energizing relay 139. Flipflop circuit 200 is thereby set oscillating, so that relays 140, 141 are alternatively energized to open and close switches 140<SP>2</SP>, 140<SP>3</SP> and so produce a series of pulses at solenoid 134 or 135 to drive the lower arm 134<SP>1</SP> or 135<SP>1</SP> until it is realigned with the upper arm, and at solenoid 41 or 42 to advance the fare stage printing wheel a corresponding number of steps. Relay 138 or 147 is then re-energized and switch 138<SP>2</SP> or 147<SP>2</SP> opened to de-energize relay 139 and turn off flip-flop 200. Whilst the flip-flop is causing the lower arm of, say, switch 130 to be re-aligned, switches 139<SP>2</SP>, 139<SP>3</SP> are closed to latch the relay 147 of the non-affected switch 131 to prevent it being de-energized on adjustment of its upper arm, until the first switch 130 has been re-aligned. This prevents the closure of switch 147<SP>4</SP> part way through a pulse, since this could result in the shortened pulse operating solenoid 134 but not 42, so that the fare stage print wheel becomes out of step with wafer switch 130. Whilst a wafer switch is being re-aligned, switch 138<SP>2</SP> or 147<SP>3</SP> is opened to inactivate the fare box unit.
