Abstract: 13,282. National Cash Register Co., [National Cash Register Co.]. June 11. Receipts, checking and recording. - In a cash register where a number of counters are mounted on a carrier so that any one of them can be brought into position for gearing with the driving- mechanism, means are provided for disabling the connections which bring the selected counter into gear, and for compelling the use of one of a set of special clerks' keys before the adjustment of the multiple counter devices. The reel 3, Fig. 1, carrying the counters 4, is pivoted to a bar 5 which slides between guides 6 on the frame, and, when this bar is slid upwards, the counters gear with one of the toothed segments 7 which move to correspond with the amount keys depressed. When the cam 9 carried by one of the rotation shafts 8 keeps the roller 10 fixed to the bar 5 depressed, the counters are out of gear, and the reel may be rotated by a rack 17, which acts on a pinion fixed to the reel and is moved by means of a bell-crank lever 14, 13 and link 12. To the lever 14 is pivoted a latch 16, which engages in notches in the plate 15 and has a tail-piece 17 bearing upon the longer arm of a lever 18, secured to the shaft 19 and having its shorter arm under the shoulder of a collar 20 fixed to a shaft 21. The other end of this shaft carries an arm 22, Fig. 4, normally projecting into a notch in a disc 23 on one of the rotation shafts of the machine. When the latch 16 is raised out of a notch, the shaft 21 is thus caused to turn and the arm 22 is drawn away from the disc 23. A spring bolt 25 shoots out and prevents the arm from returning into the notch. The operating crank handle 26 is geared to the disc 23. The clerks' keys 27, Fig. 3, act upon a detent 28 and a spring- drawn latch plate 29, to which an arm 30 is coupled by a slot-and-pin connection. On the shaft 19 is secured an arm 31, which is in contact with the end of the arm 30, unless that arm is displaced by the depression of one of the clerks' keys. The bar 5 is slid to and fro by motion transmitted from a cam 44, Fig. 2, on a motion shaft 42, by means of a link 41, arm 40 loose on the shaft 34, plate 38 to which the arm 40 is pivoted, pin 37 taking into a notch 36 in an arm 35, shaft 34, arm 33, Fig. 1, and pin 32. The keys 47 of a short bank are used for denoting special transactions, and co-operate with a detent 48 and spring-drawn latch plate 49. Pivoted to the latter is a lever, the short arm 51 of which normally confronts a pin 52 on the plate 38, so that, when one of the special keys is depressed, the plate 38 is displaced and the pin 37 no longer acts upon the arm 35. To add amounts received on account, the arm 53 of the lever is connected to the corresponding key 47 so that the short arm is displaced, when that key is depressed, and does not act upon the pin 52. In another form, a lever 61, Figs. 1<a> and 2<b>, is pivoted on the shaft 8 carrying the sectors 7, and, when rocked, raises the bar 69 by means of a pin 63 and the edge of a slot 62 in the lever. A pin 67 on the lever, provided with a roller, takes into one or other of two grooves 65, 66 in a cam 60 on one of the shafts of the apparatus, according as the link 69 and arm 71 are raised or lowered. A pin 70<a> on the lever 61 works in a slot 70 in the link 69. The shaft 72 carries at its other end an arm 73 which is rocked when a key 82 is depressed. The arm 73 is connected by a link 74, arm 75, shaft 76, and arm 77 to a camnose 78 which is acted upon by a flange 79 on a sector 80, when the latter rotates, so as to rock the arm 73 still further.
