Abstract: 12,456. National Cash Register Co., [National Cash Register Co:]. June 1. Receipts, checking and recording. -In a cash register of the type described in Specification No. 2943, A.D. 190t, a movable carriage for printing the amounts of the transactions in separate groups is provided, together with a series of independent registering - counters, and of independent cash receptacles with special locking-devices. An improved printing- platen is provided, and the main shaft may be rotated by an electric motor. In the general operation of the register, a segment 20, Fig. 3, carries a latch 21, the point of disconnection between the latch 21 and a plate 22 being determined by the depression of one of the bank of keys 70. The plate 22 is oscillated at each operation of the machine by connection with the main shaft 24. Any number of banks of keys may be employed, each provided with a segment 20 actuating a totalizing- counter (not shown) and set indicators 27 through a wheel 25. The wheels 25 are connected by nested sleeves 28 with segments 30, Fig. 1, which actuate independent counters 31. A setting-lever 41, provided with a thumb-lever 42 spring-pressed into notches in a guide-plate 44, actuates a rack 35 through levers 39, 38, and so turus a pinion 34 and rotates a drum 32, which carries counters 31 round to engage the segment 30. At the same time, the lever 41 actuates a special indicator through a rack 45 and a pinion 46. The counter 31 engages with the segment 30 by means of an internal cam in a disc 50, the carriage 51 carrying the drum 32 being lifted at each revolution of the shaft 24. The notches in the plate 44 and the corresponding counters 31 are marked to belong to different clerks, while some lower notches are reserved for special transactions, such as received-on-account." The setting-lever 41 also rocks shafts 57, 55 through a pawl 52 and a ratchet lever 54. The sliding printing-carriage is set by the extent of the motion of the shaft 62, rocked by a link 61 through a link 60 attached to the lever 41. The locking- mechanism, Fig. 2, only allows that key to be operated which belongs to the clerk, in whose notch in the plate 44 the setting-lever 41 is placed. Pins 80 on the keys allow depression of the keys when notches 81 in a double-armed lever 72 on a rock-shaft 22" are positioned. The first clerk's notch 8 is positioned when the setting-lever is pheed in the top notch of the guide-plate, by movement of the levers 78, 79, from the rock-shaft 62, which is actuated through the setting-lever, allowing a spring 75 to pull the lever 72 down, the lever 78 being connected by a pin 76 to the lever 72. The lower solid arm 73 of the lever 72 locks all the lower keys 70, and, as the setting-lever is placed in the lower notches, only one particular clerk's key may be actuated corresponding to the notch in the guide-plate..; but, on reaching the first of the lower special transaction keys, a hook 82 on the lever arm 74 engages a shaft 55, and prevents further downward movement of the lever 72, although further downward movement of the setting-lever is permissible owing to the slot 77 in the lever 78. In this position, notches, 81 in the arm 74 permit any clerk's key to be operated. Another T-lever 85 has notches 86 normally allowing actuation of the keys 70, but, on slight movement caused by moving the setting- lever, the lever 85 moves slightly, preventing operation of the keys while the setting-lever is in an intermediate position. This slight movement is caused by a rock-shaft 55, actuated through the setting- lever, and carrying an arm 88 attached by a link 87 to the lever 85. A nose 89 on an arm 88 engages a recess 90 in a locking-disc 91 on the main shaft 24. When the disc starts a revolution, the nose 89 is engaged and the arm 88 locked, so that the lever 85 is locked when a key is depressed and the main shaft 24 actuated, so that the shaft 55 and the setting-lever 41 are then locked. To ensure movement of the setting-lever before a key may be depressed, a lug 98, Fig. 3, is formed on the usual key detent 97, the lug being adapted to engage a notch 96 in a curved arm 95 on the rockshaft 57, actuated from the setting-lever. Thus, a key cannot be depressed until the lug 98 and'the notch 96 are aligned by movement of the arm 95 through the setting-lever. To maintain the arm 95 in this raised working-position, a pawl 92, Fig. 5, is fixed on the shaft 57, having a nose 92<b> engaging within a recessed locking-disc 93 against a spring- actuated plunger 94, which springs out and prevents return of the pawl 92, when it is depressed by raising the arm 95 on rocking the shaft 57. The disc 93 is then rotated by the gear-wheel, and allows a spring 92<a> to withdraw the pawl 92 into the recess 93<a>, and so to lock the mechanism at the end of each operation. Each clerk is provided with a separate cash receptacle in the cabinet beneath the register, and any drawer is opened on depressing the proper key to operate the segment 20, Fig. 3, and the finger shaft 105, through bevelwheels 104, 103 and a pinion 102. Oneof the fingers is thus passed' beneath the proper drawer latch, and by means of any suitable mechanism from the main shaft, the shaft 105 is lifted to open the drawer. In the printing-mechanism, each segment 20, Fig. 3, carries an antifriction roller 110 moving in a slot in a curved lever 112. One such lever is provided for each bank of keys, and one lever is fixed on a shaft 113, 'the others being carried by nested sleeves on this shaft. Segments 114, Fig. 5, are fixed to the levers 112 and gear with pinions 115 on nested sleeves 116 connected to type-wheels, which are formed with the usual double characters for printing a detail strip above and a check below. Ink pads 118, Fig. 6, are brought to the inking-line by a double rack-bar, Fig. 5, actuated by an attached pin 120 engaging in a cam-groove 121 in a disc 122 attached to a gearwheel 123, actuated by gear-wheels 124, 125 from the main shaft 24. The type-wheels are aligned oy pawls operated from the main shaft. The detailstrip printing-devices comprise a platen lever 138, Fig. 5, carrying a platen roller and attached to a pivoted lever 135, which is moved twice in one operation of the main shaft 24, to ink the types and print the strip, by a pin 134 engaging in a camgroove 133 in a disc 132 mounted on the shaft 131, which is actuated from the shaft 24 by gear-wheels. The strip is mounted on a carriage sliding on transverse guides and moved by an attached rack 143 engaging a sector 144 on a shaft 145, actuated from the setting-lever through the rock-shaft 62, a segment 151, a mutilated pinion 150 on a shaft 149, and bevel-wheels 147, 148. A concave locking- part 153 on the pinion 148 engages a convex portion 154 on the segment 151, so that this segment only moves the carriage during a part of its rotation corresponding to the motion of the setting-lever over the lowest four notches, but, on raising the setting- lever into any clerk's notch, the carriage is locked in the position with the "cash" column opposite the type-wheels. The carriage is locked in any position by a rotatable locking-disc with a bevelled edge, fixed on the shaft 131, and engaging a notch in a bar fixed to the carriage. The paper strip is fed by a ratchet-wheel 167, Fig. 6, rotating a winding-roller 162, on which the paper passes from a storage roller 160 over antifriction rollers 161. A link 164 fixed to the shaft of the platen roller 139 actuates a lever 165 carrying the feed-pawl 166 of the ratchet 167 at each downward movement of the platen frame. A double check perforated between the duplicate impressions is printed by two rollers 174, 175, Fig. 6, fixed to gear-wheels 172, 173, actuated by gear-wheels 171, 170 from the shaft 131. The paper passes between feedrollers 182, 184 and the printing-rollers, the feedrollers 184 baing fixed to a wheel 185 gearing with the wheel 173, and ink rollers 176,177 are provided. The rollers 174, 175 print a consecutive number and date and other matter. The paper now passes between a stationary knife 186 and a knife 190 on the main platen carriage 187 to be printed by the type-wheels 117. The resilient platen block is mounted on a carriage. 187 sliding vertically in a guide-frame 188, and reciprocated three times at each operation by a cam-groove in a disc fixed to the feed-roller 184 engaging a pin in a pivoted lever attached to the carriage. An auxiliary platen 201 carries a pin engaging in a slot 203 in the pivoted lever 204, to which is fixed a pin engaging in a cam-groove 207 in a disc fixed to the roller 184, to oscillate the lever 204 and the auxiliary platen twice at each operation. In this way, two impressions are taken on the same check. The intermittent feed of the check paper is produced in the usual way by cutting away the feed-roller at certain points. The check is perforated by teeth 210 on the roller 175. The rollers 182, 184 are furnished with eccentric bearings to throw off the check feed by means of a link 211 connecting arms from each bearing. The main shaft may be rotated by a handle or by an electric motor, through which the current is started by the depression of any key, being afterwards automatically broken. The motor may be connected to the main shaft by a magnetically-operated clutch. A plate 300, Fig. 2, sliding by means of a groove 301 on the shaft 22<a>, is depressed by the pin 71 of any key 70 against a spring 300". An arm 302 of the plate 300 extends downwards and forwards into contact with a forward arm 303 of a bell-crank lever 304, closing contacts 306 connected to the motor. The depression of the plate 300 moves the arm 302 out of the path of the arm 303, allowing the spring 305 to depress the arm 304 and close the motor circuit. In this position, the hooked end of the arm 303 htcbes over the arm 302, locking the plate 300 in this position. The lower end of the plate 300 slides on
