Abstract: 347,271. Checking receipts. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Brand, S.; 144, Forrer Boulevard, Oakwood Village, Dayton, Ohio, U.S.A.) Jan. 25, 1930, No. 2656. Convention date, Jan. 26, 1929. [Class 106 (i).] Cash registers adapted for multiple-item transactions ; voucher-issuing ; printing on inserted material.-In a machine adapted to register and record single items and multiple-items with total, the transaction may be printed on a voucher subsequently issued from the machine or on an inserted slip, at the will of the operator, the insertion of a slip for receiving the impression automatically disabling the voucher printing and issuing mechanism. The invention is described in its application to a known machine provided with a bank of single-item and multiple-item control keys. Specifications 8119/15, 208,705, 248,763, and 249,545, [all in Class 106 (i), Calculating &c.], are referred to in this connection. Impression hammers. As usual in the type of machine illustrated a short item-printing hammer 42, Fig. 2, and an aligned total-printing hammer 43 effect the impression on the voucher-strip from the upper line of type and a lower hammer 78 prints from the lower line in duplicate on the inserted slip. The hammers are operated by spring-controlled driving levers 56, 82 cocked and released by cams on the main printer shaft 74. Voucher-feed. The voucher-strip is fed in the known manner by a pair of rolls 110, 113, Fig. 6, of which the latter is carried by a pivotal frame 118 urged by a spring 112 to press the lower roll against the upper. Slip feed. This is effected by a knurled roller 121, Fig. 18, adapted to be raised against a roll 169 by a spring 176 acting upon the lever 124 carrying the roller. The roller is intermittently rotated to feed the slip between duplicate impressions, by a pawl and ratchet mechanism operated by a rack 140, Fig. 14, gearing with a sector 136 on shaft 132 and reciprocated by a spring-controlled bell crank 144 operated by cams 147, 148, Fig. 11, through a link 159. The feed roller 121 is shifted into operative position by cams 182,183, Fig. 18, adapted to move a pitman 181 to the right between the two impressions to withdraw a stud 179 from in front of a pawl 178 on the lever 124 and thus allow the spring 176 to raise the roller into contact with the roll. After the feeds have taken place the pitman returns to separate the rolls again to allow manual withdrawal of the slip. Slip feeler. When a slip is in the machine the voucher feed is automatically disabled by the following means. A feeling finger 190, Fig. 6, is raised at each operation of the machine, by a spring- controlled lever 196 controlled by a cam 203. If a slip is encountered by the finger the ascent of the lever is arrested and means then become operative to withdraw the finger to prevent mutilation of the slip when fed. These means include a lever 204, Fig. 10, controlled by a cam 208 and adapted, when rocked, to engage a stud 215 on the lever 196 by means of a pawl 209 to return the lever to normal position. If no slip is present the stud 215 rises above the path of the pawl 209 so that no such action occurs. Voucher-feed control by slip-feeler. At each operation of the machine when a voucher is not to be issued, the mechanism shown in Fig. 6 acts to lower the feed roll 113. This is effected by a camoperated pitman 223 adapted through a lever 237 to draw a link 243 to the right and so, through a multi-armed lever 245, to rock the roll frame 118 clockwise. When however no slip is present, the ascent of lever 196, acting through a cam slot 259, lever 262, link 268 and pin 278, raises the link 243 to disengage it from its operating-lever 237 at 241 so that the check feed remains effective. Control of voucher-feed by " slip " key. When a multiple-item transaction is being entered, the issue of a voucher is not desired and the slip is not to be inserted until the total-taking operation, a " slip " key 280, Fig. 8, is depressed to cause the same disablement of the voucher-feed as when the slip-feeler operates. The key is linked at 283 with a lever 276 engaging by a pin 275 with the link 268 so that with the key depressed the link is shifted to the right to be inoperative on the link 243, Fig. 6, which therefore acts to lower the feed roll 113 to ineffective position. The key when depressed cannot return until the machine has been operated, for a spring-controlled latch 298 engages a shoulder 296 in a lever 288 rocked by the link 283 to hold the key down until, in the usual key-releasing movement of the shaft 299, the latch is raised to liberate the parts. Disablement of slip-feed mechanism when slip is absent. If no slip is in the machine and consequently the lever 196, Fig. 6, rises, a link 303 is shifted to the left and through a stud 306, Fig. 14, and lever 307 forces a catch 310 into a notch in the rack 140 to prevent operation of the slip-feeding mechanism. Control of voucher impression-hammers by slipfeeler. When, owing to the presence of a slip, the link 268 remains in its lower position and consequently the link 243 is shifted to the right, the multi-armed lever 245 rocks counterclockwise to place a flange 313, Fig. 2, above pins on the item and total hammers 42, 43. If no slip is present the slip-printing hammer 78 is disabled by the rocking of edge 258, Fig. 6, of lever 262 below a pin 83 on the hammer. Control of voucher and slip impression-hammers in total-taking. During the first cycle of a totaltaking operation all three hammers are disabled by a lever 322, Fig. 3, similar to 245, Fig. 2, and controlled by the usual total lever mechanism. When the total lever is in the " add " position, the voucher total and the slip-printing hammer are both disabled but the voucher item-printing hammer is free to operate. When the total lever is set for total-taking however a shaft 347, Fig. 12, rocks clockwise to slide a link 350 to the right and thereby rock a shaft 352 also clockwise. Fast on this latter shaft is an arm provided with a stud 355, Fig. 14, gripped by a pair of spring-controlled levers 357, 358 loose on the shaft and holding between them a stud 365 carried by a lever 366 extended at 369 to carry a stud 368 controlling the lever 322. The manual adjustment of the total lever to a totaltaking position does not effect sufficient displacement of the parts to free the total-printing hammers but produces a locking of the item hammer. At the end of the first cycle the automatic additional displacement completes the movement and all three hammers are freed, after a temporary hold-up by the pitman 181, a projection 393, Fig. 18, on which restrains the pin 368 controlling the lever 322. This liberation of the hammers is of course subject to the automatic control by the presence or absence of a slip as already described. Control of hammers by keyboard. During entry of multiple-items the total hammer 43 and slipprinting hammer 78 are disabled by the above lever 322 through a cam-edged arm 394, Fig. 12, differentially positioned under the control of singleitem and multiple-item groups of keys. When a multiple-item key is set the edge 396 is in contact with a stud 398 of a lever 399 cam-slotted to embrace a pin 400 carried by an arm fast on the shaft 352, and the parts remain in the position shown so as to lock the two hammers referred to but free the item hammer 42, this last-named hammer, however, being still subject to the over-riding control by the slip. If a single-item key is used, the edge 397 will rock the shaft 352 to free all the hammers in so far as this particular control is concerned. Resetting of hammer control parts. When any of the various hammers have operated, their locking pins such as 325, Fig. 3, in the case of the slipprinting hammer, would remain in the path of the retaining-flange of the control lever, thus interfering with the restoration of the latter. To overcome this difficulty, a cam hook 410 is positioned by the cams 182, 183 and link 181 to hold the hammer slightly raised to allow the flange to pass beneath the pin, this condition persisting until during the cycle the link is operated to free the hammer. Similar mechanisms are provided to control the upper hammers. Control of slip-feed by total lever and control keys. The mechanism already described and shown in Fig. 14 operates to prevent ascent of the slip-feeding rack 140 during the first cycle of a total-taking operation and also in all multiple-item entering operations, the arm 170 in such cases occupying an obstructing position with relation to an ear 173 on the rack. Maintaining voucher-feed inoperative. When entering the items of a multiple-item transaction, the total of which is eventually to be printed on a slip, the feed roll 113 would be lowered to ineffective position in each cycle of the mechanism described above. To prevent this repetition of action, therefore,means are provided to lock the roll in its lowered position, this being accomplished by a latch 407, Fig. 11, adapted to seize a pin 416 on the lever 116. When the machine is subsequently operated without a slip being present the link 303 moves to the left and places a stud beneath an ear on the latch so that when the lever 162 is rocked subsequently, the latch is shifted to release the feed-roll lever 116. Maintaining slip-feed inoperative during multipleitem entering. As described above, the movement of the pitman 181, Fig. 18, to the right, frees the lever 124 to permit feed. To prevent repetition of this movement during multiple-item entering, the pawl 178 is disabled by a finger so that the feed roll 121 remains in effective position until the totaltaking operation when the final rocking of shaft 352 causes removal of the finger and the subsequent lowering of the feed-roll 121. Control of slip feed roll 121 by slip-key. As an operator may wish to defer inserting the slip until after he has en
