Title: Improvements in cash registers

Abstract: 307,030. Bilde, T. E. D., and Lindvall, S. E. March 1, 1928, [Convention date]. Cash registers.-The setting-means of a cash register directly actuate the indicating, totalizing and printing devices. The actuators are differentially set by hand and handles have subsequently to be operated to complete the actions of the machine. Setting and actuating mechanism. Spring- controlled wheels 10, Fig. I, toothed at 11 and 12 to rotate totalizer wheels 35 and indicator drums 19 respectively, are differentially set by finger lugs 86 moving over scales 87, and are held in their set positions by detents 51 pivoted at 42 and controlled by the same springs 52 as the setting-wheels. As the wheels 10 move from home position they act upon a bail 46 to rock a spring-plunger 50 into operative position with respect to teeth 45 formed on the side of a bar 43 slidably mounted on shafts 30, 42. The totalizer is carried by a frame 29 pivoted at 30 and normally stands in engagement with the teeth 11, being held there by the upper edge of the bar 43 supporting a cross-rod 31 on the frame. The item having been set therefore, the bar 43 is thrust in to effect the following actions. The support of the rod 31 is withdrawn by the provision of a notch 67 in the bar so that the totalizer disengages by gravity. A projection 60 on the bar engages a pin 56, Fig. VIII, on a bell-crank 55 and thus swings a bail 58 under the noses 54 of the detents 51 to maintain the wheels 10 in their set positions. The bar also effects drawer release. Another bar 44, Fig. X, similar to bar 43 is now pushed in and by means of a projection 62 rocks the bail 58 from beneath the detents 51 and positively lowers these, through the action of a cam edge 64 upon a bail 63. The wheels 10 are therefore now released and return to home position under the pull of their springs 52. When this has occurred the bail 46<1> rocks back and frees the bar 43 which is then forced out again by its spring 47 and returns the totalizer into engagement. Indicators. The indicator drums of which there are four coupled pairs to read to the front and rear are directly set by the wheels 10 as already stated. A flash 26 is linked at 91 with the totalizer frame so as to expose the drums when the totalizer is disengaged from the actuators by the operation of the bar 43. Transfer mechanism. At transfer a pin 34, Fig. IV, on the lower wheel rotates a Geneva wheel 32, Fig. VI, and so winds up a spring 39 connecting this wheel with a four-toothed pinion 40 adjacent the next higher wheel. This pinion however is positioned to be free of the higher wheel and is normally held stationary by means of a plate 59 carried by the supporting members of the bail 58 referred to above. When the operating bar is pushed in therefore and this bail swung counterclockwise the plate 59 releases the pinions to enable them to effect transfers. The Specification as open to inspection under Sect. 91 (3) (a) also comprised the subject-matter of Specification 330,292 and the following :- Drawer release. A rotatable bolt 76, Fig. XII, (Cancelled), normally locking the drawer 71 is raised by the inward movement of the operating bar 43 rocking a latch lever 73. When the bar returns, the nose of the latch lever is able to rotate the bolt against the influence of a spring 79 and so to ride past the pin 78 on the bolt and resume its latching function. This subjectmatter does not appear in the Specification as accepted.
