Abstract: 510,708. Cash registers. NAYLOR, J. W. Feb. 4, 1938, No. 3563. [Class 106 (i)] [Also in Group XVI] In a dial-set cash register, the type segment and indicator of each denomination are geared to a common dial-set rotatable member, two or more of said members being mounted to rotate on a stationary axle out of frictional contact with one another. Setting-means. Items are set up by manual rotation of two pairs of dials 27, 28, Fig. 1, each associated with a denomination of the monetary system and provided with numbered finger "apertures. The dials of each pair are carried by bails mounted by ball bearings on a common fixed spindle 25,Fig. 5. Setting is effected by entering two fingers ofeach hand in four selected apertures and moving downwardly until the fingers abut a stop 35. The dials are flexibly retained in set position by rollers 107 urged 'into engagement with the notched peripheries of segments 103, 105 carried by the bails. Operating lever. The cash drawer is released; printing effected and the setting- means restored during the depression and return of an operating lever F, Figs. 1. and 3. Depression of the operating. lever is prevented until at least) one dial has been set and unless all the dials have been properly aligned by the retaining roller 107, Fig. 5. For this purpose the rollers are mounted on a pair of, slides 109 interconnected for simultaneous movement in opposite directions and provided with vertical grooves that, when in register, permit the passage of rods 116 projecting downwardly from a cross bar on a plunger 84 linked to the lever. The return of the lever is .effected by a spring and retarded by a dash-pot J adjustable by a knob 135. Disc indicators. The pairs of setting dials are geared to. pairs of , transparent indicator discs 37, 38, 39, 40, Figs. 3 and 6, mounted on shafts 41, 46. The discs are illuminated by a lamp E and carry opaque indicia. visible, through windows C, D at the back and front of, the machine. Printing mechanism. Each setting dial is rigid, with a tootlied sector 64, Fig. 2, meshing with a type segment 66. A record strip 68 passes from a supply , roll 67, between the type segments and a platen 73, over a feed roll 70 to a storage roll 72. The feed roll is fed step-by-step through friction wheels by the movement of the operating lever, the storage roll being simultaneously rotated by a band 74 connecting it to the feed roll. The platen is lowered to effect printing upon the depression of the operating lever. Bars 88 resiliently carried by the platen engage ,notches in the type-segments to align them prior to printing. Restoring mechanism. During the . setting of the dials, studs 132, Fig. 11, rotate therewith and raise hook-shaped levers 124. Depression of the operating lever F causes spring-urged pawls 128 to wipe past noses 127 on the inner ends of the hook-shaped levers. Upon the return of the operating lever, the pawls abut the noses and restore the levers and dials. Drawer-retease. The inner end of the operating lever F, Fig. 3, normally abuts a pawl O pivoted to a drawer latch M mounted on the pivot 133 of the operating lever. Upon the depression of the lever, the pawl and latch are raised to release the drawer K. Continued depression of the lever causes the pawl to strike a stop P and rock clockwise out of engagement with the lever, whereupon the latch returns to operative position and a hammer R mounted on the latch strikes a gong S.
