Abstract: 248,763. National Cash Register Co., (Assignees of Shipley, B. M.). Jan. 19,1924,. [Convention date]. Cash registers with item-printing mechanism. -In a machine, such as that described in Specification 227,861, adapted for registering and recording single-item transactions and multipleitem with total transactions, the voucher or slipfeeding mechanism is controlled according to the character of the operation so that a normal long feed or line-spacing short feeds may be imparted. Specifications 8119/15 and 248,002 are referred to. Voucher-issuing.-The voucher strip passes to the tear-off opening between a feed-roller 582, Fig. 5, and a co-operating pressure roller carried by a lever rocked to disable the feed by manipulation of a pivoted cam-edged finger piate similar to that shown at 652 in Fig. 9. The feed roller is advanced, at each operation, by a pushrod 605, Fig. 1, driven by the main shaft and adapted to rock a sector 174 geared with the feed. pawl arm 588 restored to normal position by a spring 599, lever 598, and link 594. The full length of feed occurs in single-item transactions and total-taking operations, but in multiple-item entering a hook-shaped arm 604 pivotally mounted at 219 is rocked to the left into the path of a pin 614 on the sector so as to limit its return stroke. The arm 604 is controlled through flexible connections by the shaft 219 which is rocked under the action of a cam 615 set by the single-item and multiple-item keybank differential mechanism and engaged by a roll 616 on a lever 617 loose on shaft 219 but connected with it by a roller 629 engaging a slotted fast arm 221 and a sinuous slot in the lever 617. In multiple-item total-taking operations the initial rocking of shaft 268 by the manual displacement of the total lever causes a roller 625 on a pitman 624 to act upon an arm 626 and thus turn the shaft 219 clockwise to an extent insufficient to remove the hookshaped arm 604 from effective position. When the shaft 268 is subsequently rocked farther for the second cycle of operaton the arm 604 is fully removed to allow the long feed. The initial displacement of shaft 263 does not raise roll 616 out of the influence of cam 615 by the mechanism so far described, and therefore the link 628 carried by an arm 627 fast on this shaft is provided so 'that by its downward movement in the straight slot of arm 221 the roller 629 can rock the lever 617 and thus raise the roll 616 out of the influence of the cam 615. Printing on inserted material. - The machine may be arranged for printing on inserted slips instead of issuing vouchers. In multiple-item transactions the slip is line-spaced by means of a feed roller 774, Fig. 9, mounted in a frame pivoted at 777, and normally occupying a non- effective position as shown to permit insertion of the slip. The flame controlled by a spring 778 has a pin 779 engaging a spring-influenced lever 780 carrying a pawl 782 pivoted at 783. The pawl is drawn by a spring against a pin 784 and is also engaged by the end of a lever 805 loose on shaft 777 and regulated in position by a cam slot 810 and a pin 808 mounted on an arm 809 fast on the shaft 219 referred to in the preceding paragraph. The pawl 782 is shouldered to engage a pin 790 on a plate 791 rocked clockwise and back again by link 799 and lever 798 driven from the main shaft. In a multiple-item entering operation, the clockwise movement of the plate permits the lever 780 to rock counterclockwise until stopped by a stationary pin 803. Meanwhile the pawl, due to the position of lever 805, is tilted upwardly so that on the return stroke of plate 791 the driving pin 790 passes idly below the pawl, and consequently the feed roller 774 remains in its upper and effective position. In a single-item transaction or the total-printing of multiple-items however, the rocking of shaft 219 as described above moves lever 805 counterclockwise so that pawl 782 is not tilted but functions to restore the roller 774 to its lower position at the end of the operation. Specification 249,545 is referred to.
