Patent GB-268997-A (GB)
Abstract: 268,997. Marks, E. C. R., (Ohmer Fare Register Co.). May 28, 1926. Platen - impression arrangements; roller inking- arrangements.- Comprises a recording fare register which indicates the amount of fare received, the zone in which it is received, the direction of travel of the vehicle, and the number of passengers per trip, and records, by printing on a strip, the above information together with the date and the conductor's key number. The fare indicator consists of two independent members which, together with their associated type wheels, are positioned by separate rods which run lengthwise through the car. The record-printing mechanism and the zone indicator with its type wheels are actuated bv cords estending through the car. The passenger counter and the zone indicator mechanism are interlocked, and the whole of the mechanism is adapted to be locked by the removal of the conductor's key. The fare indications are marked on two bands 1, Fig. 1, one band having a single series of digits, and the other bearing more than one series of digits. The bands are carried by pairs of drums, 2, 6. Figs. 3, 4 and 5, which are geared to independent, shafts 7, 8. These shafts are set by rods which extend through the car, and the bands are held tiglit by rollers 19 carried by pivoted arms 18. The drums are connected by gearing with type-wheels 20, 21, Fig. 1, which print the amount, of fare upon a record strip when the printing mechanism is actuated. In order to position the fare indicators and fare type-wheels, and to lock them during the printing operation, each drum 2 is fitted with a notched disc 65 which is engaged by a roller 66 on a pivoted arm 67. The locking is effected by studs 70, Fig. 5, carried by arms 268 which are rocked downwards when their connected arms 72 are rocked by the engagement of pins 74 with cam surfaces 73. The pins 74 are mounted on levers 38 which are actuated when a bar 39 is moved upwards to operate the printing mechanism. The zone in which the vehicle is travelling is indicated by drums 91, 92 connected together by transfer mechanism and actuated step by step by external arms 94, Fig. 3, when cords running through the car are pulled. Corresponding type-wheels 102, Fig, 1, are set from the transfer mechanism. The number of passengers carried on each trip is indicated on wheels 31, the units wheel having a ratchet 33, Fig. 5, engaged by a pawl 34 on a pivoted arm 35 which has a pin 43 adapted to be engaged by a lug 42 on the arm 38 upon each actuation of the bar 39 when printing &c. is effected. This indicator is zeroized at the end of each trip by pulling out a knob 51, Fig. 1, to unlock it. and then rotating a shaft 32 through gears 48, 49. Type-wheels 55, which are not zeroized, are provided to print a total or serial number on the record strip. They are advanced upon each actuation of the machine, by lugs 63, 64, Fig. 3, on the slide 36, engaging a pivoted arm 62. A direction indicator 114 is set by a pin-and-slot connection with a gear 117 which meshes with a gear 116 on the counter zeorizing shaft 32. A link 120 connected with the direction indicator, and associated with the zone indicator actuating mechanism, sets a type-wheel or segment to print the direction on the record strip. The date type-wheels 145 are set by knobs 146 arranged outside the casing. The end of the conductor's locking key 140 is provided with a type face to mark the record strip. The record strip 181 is taken from a supply roll 180, Fig. 5, over a platen 252 to a takeup roll 183. The platen is mounted on a shaft 152 carried by oscillating brackets 151, and has a gear 153 meshing with a curved rack 154 secured to the sub-frame 147. In this way a compound movement is imparted to the platen when the brackets 151 are oscillated by links 161 connected to discs 163 on a shaft 164. This shaft is rotated when the bar 36 is actuated by pulling on a cord 44, Fig. 3, which extends through the car, the mechanism for this purpose being shown in Fig. 11. A rack 173 on the bar 36 meshes with a pinion 172, and drives a disc 169 on its upward movement only. The movement of the disc is transmitted through gearing to the shaft 164. Overthrow of the printing mechanism is prevented by arranging on the shaft 164 a cam 175, Fig. 12, adapted to be engaged by a pivoted catch 176 when the end of the bar 36 passes a feeding roller 178. An ink roller 155 carried by a spring-pulled arm 156 wipes the type wheels during the movement of the carrier 151, and is normally held in the position shown by a fixed cam. A shield 182 holds the record strip off the ink roller. The record strip takeup roller 183 is rotated by pawl-and-ratchet gear connected with the carrier 151. As the roll increases in diameter a feeding arm 194 moves a, mask over the ratchet in order to give uniform feed to the record strip.
