1,034,856. Taximeter. BELL PUNCH CO. Ltd. May 29, 1964 [June 7, 1963], No. 22766/63. Heading G4T. In a mixed time and distance drive taximeter, the display means are actuated by electric impulses caused by a switch intermittently operated by a cam 48 (Fig. 4, not shown) rotated by a clutch plate 47 which co-operates with a clutch plate 46 driven by a main shaft 30. The distance drive 18 acts through gears 19, 20, 21 and selective gears 27, 28, 29 (Fig. 8, not shown) according to the tariff, the selection being made through a push-button to operate a solenoid 34 (Fig. 4) to drive shaft 33 (Fig. 8) and hence gears 29. Cams on the distance drive contact microswitches 26, 26a (Fig. 4) to operate solenoids of " total " and " paid " miles counters. The distance drive shaft 28a is connected to a main shaft 30 through a clutch 29a. Also connected to the main shaft 30 through changeable gears to accommodate different waiting time tariffs is a clock mechanism 37 operated by a spring 33 wound by a rotary solenoid 34. The clock is stopped by a stop clock solenoid 38 when the taxi is not hired. The contactor cam 48 on the main shaft 30 closes the microswitch 51 (Fig. 1, not shown), as it rotates, which energizes a solenoid 45 (Fig. 4) to disengage clutch plates 46, 47 and enable a spring 49 to return cam 48 to its initial position, bouncing being prevented by engagement with a spring-loaded stop 55. Pulsing of switch 51 operates the solenoid 57 (Fig. 12, not shown) of the fare counter. The solenoid 57 a toothed, farenumbered wheel 60 carrying cams 61, 61a engaging with a link 62 to operate a microswitch 63 to operate the solenoid 57 of the next highest order or to open the circuit for zeroizing currents. A mechanism similar to Fig. 12 receives impulses from the main shaft and does not pass them to the fare counter till the microswitch 63 is closed, corresponding to the initial distance fare. The initial fare on the indicator is covered by a shutter in the " For Hire " condition. A press-button control operates a counter for extras.
