Abstract: 14,233. National Cash Register Co., [National Cash Register Co.]. June 23. Receipts, checking and recording.-Key-set, leveroperated cash registers of the Hall wood type described in Specification No. 1653, A.D. 1902, are modified as regards the locking, releasing, and restoring of the main and auxiliary yokes, and, in order to prevent irregular operation by the clerks, each of whom has a separate cash drawer and operating-lever, means are provided for locking the levers while the drawers are closed, indicating the operation of the levers and the movement of the drawers, printing the transactions for each drawer on its own record-strip as the lever is moved and feeding the strip by the stroke of the drawer, setting the amount indicators to zero by operation eitber of a drawer-release key or the yoke-release key, re-latching the same indicator pawls from the main yoke, and interlocking the levers and yokerelease key. The keys, Fig. 2, set stops against which the segments 6 of auxiliary yokes 5 are arrested when the main yoke 8 is allowed to fall, the printing-segments and amount indicators being simultaneously set, and when either lever 9 is drawn down, the projections 12 on the segmental rack 11 to which it is attached lift and restore all the yokes to their normal position, actuate the totalizing-counter wheels 1 by means of pawls 3, and print the item. A machine with two drawers and levers, one at each side, is shown. Normally, the arm 13, Fig. 3, is locked, to keep the main yoke in raised position, by the hooked end of an arm 14<a> which can be depressed by pressure of the yoke-release key 17 on the arm 14<b>, both arms being loosely mounted on the shaft 15 and arranged to interlock in one direction only. To open either drawer 18, the corresponding drawer-release key 27 is depressed, the book 24 is raised by means of the lever 26, and, as the drawer is forced out by its spring, the detent 22 falls behind the flange 23 and unlocks the pinion 20 so that the proper lever may be operated and the clerk identified by outside indicators oh the shaft 43a, which are set by pins on the levers and intermediate linkwork. Above these is an additional indicator showing " sale not registered " when the machine is left with a drawer open, or "amount purchased after it is closed, operated by the cross-bar 76, resting on the inclines 77 of the drawer ends and pivoted to the rod 75, which is spring-pressed downwards. On the downward stroke of a lever, the pinion 20 rotates a sleeve 51, Fig. 4, and the wiper 53, lever 52, and platen 55 give an impression against the type-segments, of which there is a set for each drawer, the ratchet feed-wheel 61 for the paper 56 being actuated by the pivoted piece 69 on the drawer and the pawl-bar 68, 66. The indicator detents 80, pivoted to the shaft 81 with depending arms 82, are put out of action when one of the three release keys is depressed, links 90 throwing down spring latch-plates on the spindle 85 to allow the depending arms to be moved inwards by a spring. These arms and detents are relatched at the end of the downward stroke of a lever by means of the link 91 and arm 96, Fig. 5, which derive motion from the main yoke, the slotted cam-parts 98, 99, 100 interacting with a pin on the rock-frame 92 to restore the plates. Transverse spring bolts forced apart by the projection 102 on the yoke-release key, and holes 106 in the racks with which they register, form an interlock between the keys and levers.
