Abstract: 878,919. Cash registers. ALLEN BUSINESS MACHINES Inc., R. C. May 25, 1959, No. 17736/59. Class 106 (1). An adding machine and cash drawer combination adapted for use as a cash register, is provided with visual indicating means. As described, a visual indicating attachment 14 is provided for an adding machine and cash drawer combination 12, which is manually operated by a crank 22. The apparatus comprises three columns of amount keys 30 and a column of item keys 34. Indicator tab magazine assemblies 50, 52, Fig. 6, are provided for indicating amounts, and an assembly 54 is provided for indicating item or total. Four levers 88 pivotally mounted on a shaft 86 are arranged to co-operate with the assemblies 50, 54. Each lever 88 has secured thereto a flexible cable 92 which is differentially moved according to the number key depressed in the associated keyboard denomination. The levers 88 are thus rocked to move rods 108 carrying abutment members 110 which members are positioned to actuate the appropriate indicator tab when the crank 22 is operated. The tabs 124, Fig. 9, each comprise a lower latch portion 126 and an upper indicia portion 128, the latch portions 126 being urged into latching engagement with the indicia portions 128 by springs 158, rotation of the rods 108 causing the abutment members 110 to release the required latches, thereby allowing the indicia portion 128 to be urged upwardly by a spring 164 to a visible position. Force transmitting rods 178 connected to the latch portions 126 are adapted to actuate corresponding members in the second indicator tab magazine assembly 52. Actuating means for the indicator tabs comprising a bar 180 pivotally connected to an arm 186 on the cash drawer are operated on the return stroke of the machine after the amount has been set up. During the forward stroke, resetting means are effective to restore the actuated tabs. Resetting is effected by a rod 200 carrying a transverse bar 208 having blades 210 secured perpendicular thereto being moved downwards, the blades 210 engaging notches 152, Fig. 9, in the actuated indicator tabs to return them to the latched position against the action of the springs 164. Actuation of the rods 108 which have been positioned in response to the amount set up on the keyboard takes place at the end of the stroke of the link 180, a pin on the end of the link 180 contacting a pin on a member fixed to a vertical shaft 238, which is rotatable about its vertical axis. Rotation of the shaft 238 causes lateral movement of a bar 252, Fig. 6, which contacts abutment elements on the rods 108 which rotate to effect release of the index tabs by means of the abutment members 110. A further tab assembly 276, Fig. 10, is actuated by the total and sub-total keys, the lower end 278 of the corresponding latch portion being foreshortened to prevent its engagement by the abutment member 110. Actuation of a total or sub-total key results in a bar 314, Fig. 10, being raised to raise a plate 294 pivoted on the bar 252, subsequent reciprocation of the bar 252 causing a pin on the plate 294 to pivot a crank 282, thereby releasing the total indicator tab latch 278. Means 62 are provided to render the indicating means ineffective, rotation of a shaft 316 causing the link 180 to be raised clear of the indicator tab release means.
