Patent GB-458087-A (GB)
Abstract: 458,087. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A. (Assignees of Herman, E. W.; 301, Orchard Drive, Dayton, Ohio, U.S.A.) June 11, 1935, No. 16772. Convention date, June 16, 1934. [Class 106 (i)] In a cash register or similar accounting - machine having a plurality of totalizers, a manual selecting means for each totalizer and individual locking means adapted to prevent operation of said selecting means, means are effective, when one of the selecting means is locked, automatically to condition another selecting means for operation during a successive machine operation or operations. The invention is described as applied to a machine of the kind forming the subject-matter of Specifications 135,465, 140,363, and 267,629, [all in Class 106 (i)]. The machine is provided with two clerk's keys 43, 44, Figs. 1, 5 and 6, each associated with a totalizer (B, A, not shown), the key 44 associated with the A totalizer being redundant except in so far that its depression assists in coupling selected keys to the key coupler 47 in known manner. If no clerk's key is depressed, totalizer A is automatically selected while if key 44 associated with totalizer A is locked by a lock 142, totalizer B is automatically selected. If both clerk's keys are locked by locks 141, 142, amounts may still be entered into totalizers A, B, in known manner, upon the positioning of the usual control lever 283, Fig. 6, to "Unlock A-B " position. In such an operation, totalizer A will be selected automatically, or totalizer B upon the depression of the associated key 43. Automatic selection of totalizer A. The usual totalizer-engaging mechanism is provided, comprising (for totalizer A) a pitman 93, Fig. 9, lowered during each operation by cams 84, 85 and adapted by cam slot 95 to rock the totalizer into engagement with actuators 68, the connection between the cams 84, 85 and the pitman including a bellcrank 81, 91 and a cam-slotted link 100 pivoted thereto and embracing a pin on the pitman. The pitman of the totalizer that is not to be selected is rocked downwardly in usual manner, to ineffective position by the clockwise rocking of the associated cam-link 100 by a throwout bail 106 or 107, pivoted to the link and operated by a pin on the selected clerk's key. However, if no clerk's key is depressed the engaging means for totalizer B is automatically disabled by a lever 131, that is operated to rock the throwout bail 107 for that totalizer by means of a link 129 operatively connected to a cam-slotted link 133 rigid with link 100. In an operation in which totalizer B is selected by depression of clerk's key 43, links 100 and 133 are rocked clockwise to render lever 131 ineffective to rock the bail 107. For this purpose a lever 124, Fig. 5, is pivoted on the key shaft 45 and is rockable by a pin 126 on the key 43, a stud 127 on the lever serving through a lever 128 to rock the throwout bail 106 for totalizer A. Automatic selection of totalizer B. Upon the locking of clerk's key 44 associated with totalizer A, totalizer B is automatically selected. The locking movement of lock 142, Figs. 1 and 5, operates through a lever 153 engaging a stud 158 on a lever 154, to rock the latter counter clockwise. The lower end of lever 154 is forked to straddle a link 167 and a stud 160 on a slide 161, counterclockwise rocking of the lever 154 normally serving to shift the slide 161 to the right, in which position it is coupled to the key coupler. Now upon the rocking of the coupler by the depression of amount keys, lever 124, upon which the slide 161 is mounted is also rocked to throw out totalizer A. Release of clerk's key locks by control lever. In locking position, the locks 141, 142, Fig. 1, serve to situate edges 149, 156, Figs. 1 and 6, of levers 146, 154 in the paths of studs 150, 157 on the clerk's keys, in known manner. Also in known manner, the movement of the control lever 283 to " Unlock A-B " position serves to displace the levers 146, 154 to a position in which the studs on the keys are free to move within recesses in the levers. To effect this, the control lever is geared to a shaft 80 carrying a cam 282 adapted to rock a bell-crank 278 and with it the levers 146, 154. In order that totalizer A may be automatically selected upon movement of the control lever to " Unlock A-B " position, in spite of the fact-that its associated key lock 142, Fig. 5, remains in locked condition, the operative connection between lever 154 and slide 161 is broken. A cam 307, Fig. 5, is provided on shaft 80 for this purpose, and serves through bell-crank 310 to shift the slide 161 to uncoupled position and by link 166, coupled to the bell-crank, to lower the link 167 and thus free the slide for this movement. Item-counters. A counter 187, Fig. 11, and 204, Fig. 1, of known type is provided to count the number of items entered on each totalizer. The deep-tined operating pawl 192 of counter 187 is rocked at each machine operation by an arm 199, Fig. 5, of the key coupler. An arm 206, Figs. 1 and 11, carrying the operating pawl for counter 204 is rocked by the lever 124, Figs. 1 and 5, each time totalizer B is engaged, and by means of a disc 216 disables pawl 192 for counter 187 during those operations. Cash-drawer selection. A cash drawer is provided for each clerk and is released upon the engagement of the associated totalizer. The drawers 234, 235, Figs. 1 and 2, are arranged side-by-side and are -normally held closed by latches 236, 237 on the drawers engaging over bars 240, 241. The latches are selectively disabled by the rocking of levers 243, 244 consequent upon the upward movement of a selector plate 250 on a release shaft 249. This plate is normally in position to select drawer 234 associated with totalizer A, but is rotated through a link 263, upon the rocking of lever 124 associated with clerk's key 43, to select drawer 235. The upward, releasing movement of shaft 249 is effected upon the return of the key coupler by the engagement of a projection 261, thereon, with a byepass pawl 257 on a lever 255 connected to the shaft by a cranked link 253. Tablet indicators. The indicator tablet 219, Fig. 1, for the " A " clerk's key is permanently raised. Upon the engagement of totalizer B, by the depression of its key or automatically, tablets 218 are raised to view on each side of the fixed tablet which is thus concealed.
