Title: Improvements in cash registers
IPC: G06C7/10

Abstract: 141,012. National Cash Register Co., (Assignees of Pein, E. J. von). March 29, 1919, [Convention date]. Cash registers; machines with several item-value totalizers; with item - printing mechanism; printing totals and sub-totals.-Key set and operated coupler machines are provided with a " grand " totalizer, adapted to be read directly, and with a non-readable " registering " totalizer the elements of which are adapted to set a special set of total or sub-total type wheels, and to be zeroized positively when a total is printed. Means are provided for printing items and characters on both inserted and record strips, and also whereby the transactions shown on the inserted strip may be summed up for a few or all of the items. In Figs. 1A and 1B the grand totalizer is shown on the left and the registering totalizer on the right. Each operation of a key 30 raises the keycoupler 32 and through a double rack gives a complete revolution to a main operating-shaft 54, Fig. 5, A differential segment 44, Fig. 5, is given a movement corresponding with the value of a key through a gap in a piece 36 engaging a bar 39 carried by the segment frame 40, of which there are four. Four differential segments 44 are provided for each totalizer, corresponding segments being coupled together. The totalizers are carried by frames 50, 51 and are rocked into gear with the segments by throwing-levers 55, Fig. 5, cam-operated from the shaft 54 and engaging spring plungers 313 carried by the frames. The registering elements of the grand totalizer are provided with numerals which may be read, but the elements of the registering totalizer are connected to pinions 47, Fig. 5, which mesh with pinions 48 rigid with scroll plates 57 adapted to be engaged by pins 1135 on arms 132 carried by nested sleeves 133. The segments 44 for this totalizer are connected to item printing means through nested sleeves 66 and shafts 67. The special keys 88, 89, 90 are connected to one of the sleeves 66, and thence to a type carrier having letters C. R. P. The keys 89, 90 when operated displace a pin so as to render inoperative the mechanism for engaging the grand totalizer with the segments 44. The " no-sale " key opens the cash drawer as usual. The items entered on the totalizer are shown to the purchaser by indicators 100. The sleeves 66 connect through gears and coupling-shafts with nested sleeves 73, Fig. 9, on a shaft 74, Fig. 13, and provided with type carriers 75. Pawls 80, Fig. 12, aline type during release of a platen 82 pivoted at 84, the pawls and the platen being operated by cams on the shaft 54, Fig. 8. The record-strip 103, Fig. 12, runs from the roll 104 over guides 105 to a storage roll 106 on a shaft 107 which is driven by a pawl 115 and ratchet 114 from a plate 118, Fig. 8, reciprocated by an arm 180 rigid with the key-coupler 32. The storage roll gives motion to the inking-ribbon 108. To print a total, the handle 180, Fig. 15, is given two revolutions clockwise. A 2 to 1 gearing to shaft 150 causes the latter to make one revolution counterclockwise, a pawl preventing reversal. A plate 186 fast with the wheel 156 co-operates with a two-armed stop 191 to arrest the wheel after a complete revolution. Cams 169, 170 on the shaft 150 rock a lever 165 pivoted at 166 and fast with a segment 129 which through spur-andpawl mechanism drives the shaft 107 and record and inking ribbons each time a total is recorded. The record strip may be operated by hand from the button 276. The slip with the items entered by the clerk is inserted in the machine between rollers 278, 279 and the keys corresponding to the first item depressed to enter the item in the totalizers, and to print it by operation from the main shaft, and similarly for the successiveitems. The sleeves 133, Fig. 5, carry segments 135. Fig. 8, which mesh with gears 136 on a shaft 137, which in turn gear with segments 174 on a shaft 175 having extensions 173 connected by springs 172 to the member 165. As the lever 165 is rocked clockwise, the angle 179 tends to move away from the segments 174, but these follow owing to the pull of the springs 172. The sleeves 133 are thus rotated until brought up by the pins 1135 engaging the positioned scroll plates 57. Racks 138 moving with the segment 136 position nested sleeves 140, Fig. 13, mounted on a shaft 141 and carrying type-carriers 130 for printing a total. After an impression, the frame 165 is rocked counterclockwise and the parts restored to normal. An alining pawl 143 and a platen 151 are cam-operated for total printing from the shaft 150. An inking-ribbon 158 for inserted-slip printing is fed by the same gear as the ribbon 108. The total printing-mechanism is .controlled by a lever 196 fast on the shaft 197. A pin 199 on this lever engages a slotted plate 202, Fig. 8, which moves a rod 206 longitudinally. This movement is transmitted to a rod 213 which moves transversely, and when the lever 196 is moved to the " eliminate " position, a member 311 on an arm 310, Fig. 1B, on the rod 213 causes a spring plunger 313 to retire into frame 51 and the plunger, being cut-away, it is out of contact with the throwing lever 55 so that the registering totalizer is not moved into gear with its segment 44. At the same time a stud 314 engages the lever 310 and locks the frame 51, and a stud 315 locks the arm 310 against rotation. Formed on the plate 200 are three notches 215 corresponding to the three positions of the control lever 196. The notches are engaged by a spring lever 316, Fig. 8, the other end of which engages a stud 222 on a slidable plate 223. When the control lever is moving from the " total " position, the projection 227 comes under a shoulder 228 on the plate 120, thereby locking the keys 30. The rear 224 of the plate 223 also passes under a shoulder 225 of the disk 226 and locks the crank 180. This arrangement of parts also lucks the control lever when a key 30 or the crank 180 is moved. The lever 196 is connected through a link 229 and sleeve 233 to a type-carrier 234 corresponding with the three positions of the lever, and also to a typo carrier 293 which prints a letter " E " corresponding to " eliminate." The motion of the lever 196 is transmitted through link 240 to an arm 244 pivoted at 245 to the segment arm 247 and engaging a stud 249 on the link 178. When the lever 196 is moved from " total," the arm 244 is swung and a pin 250 engages the fixed plate 251, locking the segment arm 247 during movement of crank 180. Normally the arm 244 moves with the link 178 and motion is given to the segment arm 247 and through gears 254, 255 to a wheel 256 and ratchet-device, and hence by gears 267, 268 and jointed shaft 269 to the recording totalizer shaft 49 which on the back stroke of lever 165 is thus zeroized. In the sub-total position of the control lever, the link 244 is diseonnected and the zeroizing-mechanism inactive. In the " eliminate " position of the control lever, the items would not be entered in the totalizer, and there is no occasion to operate the crank 180. Specifications 20280/98 and 27802/03 are referred to.
