Abstract: 12,457. National Cash Register Co., [National Cash Register Co.]. June 1. Receipts, checking and recording.-Cash registers, more particularly of the kind described in Specifications No. 13,457, A D. 1901, and No. 17,078, A.D. 1902, are provided with means to throw the counter out of action, when it is desired to indicate and d print certain transactions without registering them, to suspend automatically the action of the check - printing devices when a check is not required, to register the number of sales of different classes, and to prevent the operation of the machine until the indicators have been bidden from view. Fig. 2 shows a. machine with the parts set for a special transaction, and Fig. 4 shows the locking-devices for the operating crank handle 11. The machine comprises a series of setting-levers which set the indicators, the registering-devices, and the typecarriers. A crank handle is then operated to expose the indicators and to print and register the amounts. An additional setting-lever 2 is moved to different positions for the different special transactions, which movements determine the operation of a series of special counters and also control the movements of a special indicator. The lever 2 carries the sliding plate 24, which is bifurcated to straddle the transverse shaft 7. By means of the pin 27 and the box cam 29, the slide 24 is reciprocated each time the shaft 7 is rocked. This effects the operation of the pivoted frame 37 and the pawl 36, associated with the special counter 30, 31, 32, or 33 in line with the setting-lever 2. The five positions to which the lever 2 can be set, are " cash," "no sale," "received-on-account," "charge," and " paid-out." The special " cash " counter 44 has its pivoted pawl-carrying frame 37 connected by a link with a pivoted bell-crank lever, which is operated with each cash transaction. Each special counter is provided with a turn-to-zero knob. The aligning and locking segment 48 for the lever 2 has five notches, and the locking-pawl 49 is mounted upon the transverse shaft 50. The shaft 53 carries an arm 55 connected to the pivoted locking-pawl 56, Fig. 4, which, when the shaft 53 is rocked, is drawn forwards to move the locking-shoulder 60 out of the path of the segment 61 on the shaft 7, and leave the operating-handle 11 free. The return of the locking-pawl 56 is effected by means of the movable shaft 49<1>. Except when the setting- lever 2 is in the " cash position, the machine is locked after each operation, and is only unlocked by the movement of the lever 2. The " cash " bellcrank levers are actuated by discs being coupled to cams, on the shaft 7, by the movement of the lever 2, one of the cams acting to operate a pivoted flash for the iudicators. To turn the counter, which is mounted in a movable frame, to zero, an independent rotary shaft 98 is provided with a series of pinions 100 to engage the pinions 101 of the counter wheels. To prevent the operation of the machine until the vertically-movable carriage for the indicators has returned to its lower position, the rear edge of the segment 61 is adapted to cooperate with the pivoted lever 110, which rests upon a lever extending into the path of the carriage. In the modified machine shown in Fig. 1 <x>, the driving-gearing is different, and the throw-out counter mechanism is modified. When it is desired to suspend the operation of the registering-devices, the segments 4<x> are latched in their normal positions. The lever 30x controlling the special transactions is adjustable to four positions. The printing-mechanism is constructed for the printing of a detail strip and a check. The check-printing devices are driven by the shaft 56<x>, so that, when the action of the shaft is suspended, the issuing and printing of checks is suspended. If it is desired to issue checks upon all transactions, the depressible key 75<x> is depressed, the link 71 <x> being moved away from the pin 69<x>, leaving the lever 72<x> free to oscillate and the pawl 64<x> to engage the disc 68<x>. To prevent the issue of checks altogether, the shaft 56x is disconnected from the check-printing mechanism, through the medium of a longitudinally-movable shaft.
