Abstract: 472,680. Registering mechanism. WAYNE CO. Dec. 24, 1935, No. 35692. Convention date, Dec. 31, 1934. [Class 106 (i)] A registering mechanism having a cost indicating means adapted to operate at different unit price per unit of measure comprises a plurality of separate variable speed gear mechanisms, the summation of the movements of which is imparted to the cost indicating means through a differential gear, each of the variable speed mechanisms being constituted by a series of gear members and a gear member capable of movement relative to the said series for selective engagement to vary the drive ratio in accordance with the unit price. The invention is shown embodied in a liquid dispensing apparatus having a pump the outlet of which is connected to a meter which in turn is connected to the dispensing means and drives the shaft 48, Figs. 3 and 4, of the registering mechanism. The shaft 48 is connected to a coupling 54 provided with a gear 58 operatively connected with a drive shaft 68 which itself is geared to and drives a shaft 78, Fig. 7, on which is mounted a bevel gear 82 driving the quantity indicating shaft 86. This shaft carries oppositely disposed fractional quantity bands 90 and by means of transfer mechanism constituted by gears 92, 94, shaft 96, gears 98, 100, and clutches 104 actuates unit quantity hands 102. The gear 58, through the gear 60, drives a shaft 62 to which is secured two gear cones 106, 112 adapted to impart movement of variable extent to shafts 116, 158 in accordance with the price per unit quantity. The shaft 116 is associated with a yoke or shifting lever 124, Figs. 4 and 5, embracing a gear 122 splined to the shaft and meshing with a gear 126 on the lever and adapted to engage any one of the gears of the cone 106. The gears are held in adjusted position by a spring pressed pin 130 mounted on the lever 124 engaging a corresponding aperture in a selector plate 134. The shaft 158 is. associated with a similar selecting lever 166 and gears 164, 178 to mesh with any one of the gears of the cone 112. The motion imparted to the shafts 116, 158, is transmitted through gears 142, 182 thereon to gears 154, 184 loosely mounted on the shaft 62, and thence through a differential or epicyclic gearing to a bevel gear 194 that meshes with a gear on a shaft 196. The-shaft 196 is operatively connected by gearing 200, 202, 206, 208, Fig. 4, bevel gear 210, 212, Fig. 7, and a clutch 216 to a shaft 214, operating the total cost indicating pointers 220, 222 in a manner similar to that for the quantity indicators 90, 102. On the shafts 86, 214 are freely mounted bevel gears 258, 260 with clutch elements 262, 264 that normally co-operate with the pins of slidable clutch elements 270, 272 rotatable with the said shafts. The gears 258, 260 mesh with gears 310, 312 arranged on shafts 314, 316, Fig. 3, operatively connected to a reset shaft 342. In operation after the quantity and cost pointers have been reset the delivery nozzle is lifted from its hook and a lever 46, Fig. 7, is thereby rocked and a linkage 304, 294, 300, 292 operated to rock levers 274, 278 to disconncet the clutch elements 270, 272, so as to prevent a resetting operation being effected during a delivery operation. Specification 472,887 is referred to. Reference has been directed by the Comptroller to Specification 460,369.
