Patent GB-393323-A (GB)
Abstract: 393,323. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Brand, S. ; 144 Forrer Boulevard, Oakwood Village, Dayton, Ohio, U.S.A.) Dec. 8, 1931, No. 33978. Convention date, Dec. 8, 1930. [Class 106 (i).] Voucher-issuing adapted for multiple-item transactions.-The item, total, and fixed matter (electro) printing-hammers and the paper feed are controlled by the machine-setting so that a voucher provided with a stub is printed and issued under the various conditions demanded by the requirements of single-item and multipleitem transactions. Fig. 3 shows a voucher recording a multiple-item transaction. Control of hammers.-The hammers are adapted to be operated by two-lobed cams 71, Fig. 8, but are under the restraining control of a pivoted member 80 provided with a flange 82 to hold the total hammer 35, and with a nose 85 to lock the electro hammer 36. In all multi-item entering cycles the shaft 140, positioned in the known manner by the differential of the transaction bank, maintains the member 80 as shown to prevent the two unwanted hammers from being retracted. Moreover the item hammer 34, together with the electro hammer, is also held during the first operation of the hammer-cocking lever, i.e. by the lobe 72, by means of a yoke rocked by the paper-slacking mechanism referred to below. In a multi-item total-taking operation the manual adjustment of the total-lever, through the usual mechanism, rocks the shaft 140 clockwise slightly but only sufficiently to bring a flange 157 over a pin 156 on the item hammer so that all three hammers are held inactive during the first cycle. At the end of this cycle the shaft 140 receives further clockwise movement so that all three hammers are released and consequently, in the second cycle, the total with its characterizing symbols is printed first on the voucher proper and then, due to the action of the second lobes 73, on the stub portion. The total hammer also prints the date on the stub and on the next portion of the strip. The electrohammer is held by the paper-slacking mechanism during the operation by the first lobe, but is then freed so that, when the second lobe functions, the electrohammer prints the fixed matter on the next voucher. Paper feed.-The voucher strip 127 passes between rollers 200, 202 and to a feed roll 123 advanced by a pawl and ratchet mechanism operated by a spring-controlled sector 103. In each cycle cams on the printer shaft 70 reciprocate twice a bar 100 controlling the movements of the sector. In multi-item enterihg operations and the first cycle of a totaltaking operation the movement of the sector is limited to line-spacing by a pin 114 carried by a lever fixed to the transaction-controlled shaft 140 but in single-item transactions and for the second cycle of a total-taking operation the pin is shifted to allow the sector to make its full stroke to advance the voucher for impression on the stub. At the second reciprocation of the bar 100 the strip is again fed to issue the voucher from the machine. The roller 202 is carried by an arm 169 rocked in each cycle by cams 180, 181 so as to draw the strip from the supply roll and then allow it to go slack. By the counterclockwise rocking of the arm, yokes 163, 164 are rocked clockwise and a link 174 moves to the left to insert a hook 210 in a notch to hold the feed roll stationary during the first reciprocation of the bar 100 in a multi-item entering operation. At the second reciprocation the hook has been withdrawn so that the line-spacing feed may take place. Control of hammers by paper-feeding mechanism. -The yoke 163 controls the item and electrohammers by means of their arms obstructing pins on the hammers to prevent their operation during the passage of the first lobes 72 in multi-item entering operations. In a total-taking operation, a pin 213 is carried by the rocking of shaft 140 into engagement with a lever 175 supporting the link 174 so as to hold this and permit only sufficient displacement to the yoke to lock the electrohammer. Consequently the item and total hammers are free to impress the voucher by the action of the first lobes and upon return of arm 169 all three hammers are freed for impression by the action of the second lobe. Voucher-perforating.-The electrohammer has an extension 220, Fig. 5, carrying a comb 224 to perforate the strip to form the stub.
