Abstract: 241,213. National Cash Register Co., (Assignees of Ostendorf, L. C.). April 23, 1924, [Convention date]. Cash registers with operating means.-In keyset machines of the drawer-operated type as described in Specification 6428/09 means are provided for positively returning the totalizerresettng control key after a resetting operation to prevent injury to the operating parts of the mechanism. Drawer-mechanism. After setting up an item a release bar 30, Fig. 1, is depressed to release the drawer latch 52 through a bell crank lever 38, arms 44, 45, and link 51 whereupon the spring-controlled operating arms 55 move the cash drawer forward. A full-stroke pawl 73 on one arm co-operates with a fixed rack 74. Totalizer engaging-mechanism. The totalizer 95, which is normally engaged with the actuating segments 96, is disengaged at the beginning of an operation by a pivoted plate 97 on one of the arms 55 rocking a bell crank lever 99 and through a link 101 and bell-crank lever 102 raising a link 103 the upper end of which is bifurcated, each limb having a pin 104, 105 for the purpose of engaging notches in openings 106, 107, of plates 108, 109 secured to the shaft 110 that carries the totalizer supporting arms 111. Normally the pin 104 engages the notch in the plate 108 and on the forward stroke of the arm 55 the shaft 110 is rocked. At the end of the forward movement the arm 55 engages a roller on the bell crank lever 102 to cause the totalizer again to engage the segments. To prevent a disengagement of the totalizer at the end of the return stroke a spring-controlled arm 14 co-operates with a pin 115 on the full stroke pawl 73 and with the bell crank lever 99 to prevent counterclockwise movement of the latter. The segments 96 are loosely connected to segments 118 actuated by means of a rod 81 supported by arms 82 that are rocked by cam plates 84 from the shaft 67. Zeroizing totalizer for printing totals. Each key bank is provided with the usual detent plate 125 which holds the depressed key until released near the end of an operation by a rocking member 131 on a shaft 132 actuated by a link 133 the rear end of which is pivoted to a lever 135 having a roller 136 engaging a pivoted cam-plate 137 on the operating arm 55. On the lowering of the arm 55 the cam plate 137 passes the roller 136 but is caused to rock the lever 135 on the return movement. During a zeroizing operation when the control key 139 has been manipulated the item keys 113 are locked by means of a rod 141 on arms 140 on the shaft 132, the rocking of the shaft 132 causing this rod to engage a prolongation of the arm 126 supporting the detent plate 125. The control key is positively restored during the zeroizing operation by a pivoted lever 156 adapted to be rocked on the return of the main actuators 82 by means of a spring-controlled cam plate 150 pivoted to the rod 81. Prior to the zeroizing operation an idle operation is necessary to reset the transfer parts (not described) and to release the control key 139. The release is effected by rocking a shaft 166 to withdraw a roller 164 on an arm 172 from engagement with a notch in an arm 161 pinned on the shaft 132. When the control key is manipulated the arm 161 is lowered so that a roller 167 thereon is caused to engage a notch 168 of a lever 169 and effect through the roller 164 and link 173 a shifting of the pins 104, 105 relatively to the plates 108, 109 so as to prevent disengagement of the totalizer during the forward stroke of the operating arms. The pin 105 now engages the notch in the opening 107 so that the totalizer is disengaged on the return of the operating arms. A cam plate 174 on the upper end of an operating arm co-operates with a roller 175 on the lever 169 to disengage the arm 161 to permit the shaft 132 to return to normal position. Release of the cash drawer is prevented during a zeroizing operation by means of a link 160 adapted to move the end of a lever 159 into the path of a roller 37 on the bell crank lever 38 that operates the drawer latch.
