Patent GB-266954-A (GB)
Abstract: 266,954. Marks, E. C. R., (Ohmer Fare Register Co.). May 28, 1926. Adding-apparatus. - An adding-mechanism, described in connection with a fare-registering apparatus, comprises for each denomination a number of differently-toothed gears arranged on a carrier rotated by the setting-means to position one of the gears in operative relation with the corresponding numeral wheel of the counter. The setting-lever 23 is geared with a disc 251 carrying pinions 253 having one or more lateral teeth 257. When the disc has been set, the lowermost pinion may be driven by means of the treadle 109, rack 104, pinion 287, shaft 282 and mutilated gear wheel 286, to cause the lateral teeth 257 to actuate the numeral type wheel 284 through an idle pinion 281. The carrier 251 is held against rotary movement during the actuation of the counter by a hooked arm 289 adapted to seize a pin 255 and controlled by a cam 294 on the driving shaft 282. The pinions are prevented from rotation on their axes at all times except when in the lowest position by having a mutilated tooth 272 engaging a stationary disc 273; in the lowest position rotation is permitted by a notch 274 but the pinion is then yieldingly held by a spring-controlled slidable plate 275 the edge of which takes the place of the true periphery of the disc. To prevent overthrow of the numeral wheel the idle pinion 281 is controlled by a spring-influenced pawl 299, Fig. 12, the off-set tail 300 of which bears against a cam 301 fixed on the driving-shaft 282. The pinion 253 in operative position is also locked except during its drive by means of a similar cam 296 the raised periphery of which co-operates with a mutilated tooth 295. Transfer-mechanism.-A pinion 306 is mounted on a lever 308 pivoted at 304 and held in one of two positions by a spring-controlled detent 311. At transfer a tooth 312, by engaging a nose 313, rocks the lever counterclockwise to throw the pinion 306 into operative rediation with the next higher numeral wheel. A pinion 305 mounted on the drive shaft 282 and geared through a pinion 303 with the pinion 306 thereupon subsequently effects transfer through a lateral tooth 314 adapted to engage a pinion 314a connected with the higher wheel. The detent locking the latter is temporarily removed during this transfer operation by the provision of a gap in its controlling cam 301. The lever 308 is eventually restored to normal position by a tooth 315 bearing on a surface 316.
