Abstract: 415,435. Cash registers. NATIONAL CASH REGISTER CO., Ltd., 225, Tottenham Court Road, London-(National Cash Register Co. ; Dayton, Ohio, U.S.A.) Feb. 24, 1933, No. 5655. [Class 106 (i).] Printing totals.-In a cash register of the key set and operated type having a normally locked direct total-printing mechanism and manual unlocking means therefor, a manager's look 79, Fig. 2, is operable to permit a total to be printed on a normally ooncealed record strip, and an auditor's lock 136 is operable to expose such record strip in addition to unlocking a totalizer-resetting lever. The invention is described as applied to a machine of the kind disolosed in Specifications 135,465, 157,824, [both in Class 106 (i)], and 408,975, and provided with a record strip to take imprints from totalizer wheels on a shaft 44, Fig. 1, and from dating, numbering and other wheels on a shaft 50. The record strip, ink-ribbon mechanism and platen 60 are carried in a frame 56, rockable about a shaft 58 by a knob 76 to take an impression. The printing-mechanism is enclosed by three covers, a fixed cover 59 apertured to give access to the record strip, a normally locked inner cover 122 supported by a hinge 123 and adapted to prevent access to the record strip, and an outer cover 77 hinged to the casing and normally locked to enclose both the printing mechanism and the usual control and resetting levers 78, 142. Operation of the manager's lock 79, Fig. 2, shifts a rod 83 to the right thus positioning a notch 96 therein to free the control lever 78 and, through a bell crank 85, shifting a slide 86, Fig. 6, to the left to rock a latch 90 out of engagement with the stud 92 and thus unlock the outer cover 77. The printing-knob 76 is now exposed and, after the adjustment of the control lever to total position, may be operated to print a sub-total. Operation of the auditor's lock 136, Fig. 2, shifts the rod 83 to the left and positions slots 97, 98 therein to free both the control and resetting levers. In addition, the slide 86 is moved to the right to disable the latch 90 and through pin 140 and slot 141 rocks a lever 129 clockwise out of engagement with a hook 127 on the inner cover 122. Both the covers 77, 122, thus freed, are opened, the control lever is adjusted to total position and a total printed by depressing the knob 76. The totalizer is then reset by the lever 142 and the part of the strip showing the various subtotals and the final total is torn off and removed from the machine. The usual interlocks are provided between the control lever, the resetting lever and the printing frame. Operation of the machine is prevented, while the control lever is in total-printing position, by means of a lever 116, Fig. 1, that is rocked by a stud 941 on the control lever and intercepts the key coupler 23. The strip is fed by a knurled knob 119, Fig. 4, projecting from a winding-on roller 118, to which the end of the strip is secured by insertion beneath a longitudinal edge of a sleeve 130 that partially embraces a reduced part of the drum and is urged outwardly by a spring plunger 132. Alternatively, the strip end is secured to the roller by the usual retaining key, and the roller is rotated by a removable handle 166, Fig. 9, insertable through a hole in the casing and provided with a lateral projection that co-operates with an enlargement 170 of the hole in the casing and with a stud 168 on a spring-urged pawl 169, to limit the movement of the handle to one clockwise revolution. In a modification, Fig. 11, the impression is effected by the depression of a key lever 171 that also serves to feed the record strip into a compartment 199 beneath the inner cover 122. Upon the depression of the key lever, a stud 177 removes a latch 172 from beneath a bell crank 175 and permits the latter to rotate counter clockwise under the action of a spring 181, thus rocking the printing frame about its pivot 58 to effect an impression. The strip feed is effected by rollers 197, 201 operatively connected through a free-wheel device to a pinion carried by the printing frame and meshing with a stationary toothed segment.
