Abstract: 157,823. Remington Arms Union Metallic Cartridge Co., Inc., (Assignees of Fuller, F. L.). Nov. 19, 1918, [Convention date]. Cash registers. - A handlever 550 normally kept locked by the supervisor is placed in one of several positions for varying the working conditions of the machine and for giving access to the various parts. A subsidiary lock may be under the control of the clerk to enable him to replace the record rolls. The invention is described as applied to the machine described in Specification 135,465. The lever, provided with a handle 576 working over an indicator plate 578, may be locked in any one of three positions, viz., (1) to prevent operation of the cash register, (2) to free the machine for action with the cash drawer open, and (3) to permit ordinary use of the register, the drawer having to be closed between successive operations. After unlocking the handlever, the supervisor may also position it for printing a total and clearing the totalizers or for' merely releasing the drawer. The lever carries a notched plate 555 engaged by a positioning catch 557 and provided with three holes 563 for engagement by the bolt of the supervisor's lock 561 when the lever is placed in one of the first three positions enumerated above. Unless the lever is correctly placed and the bolt shot, a lever 580 is displaced thus bringing a lug 582 into the path of the key coupler extension 583 and so preventing use of the cash-register. The mechanism for bringing about the conditions corresponding with the first three positions is as follows : In the movement to position (1) : a cam 588 rotated from the hand-lever through gearing 554, 586 engages a pin 618 on a slide-plate 615 and so shifts a hook 619 to engage the coupler and prevent its ascent. In position (2) the slide 615 moves towards the front of the machine sufficiently to release the coupler, but its lower edge 620 is engaged by a pin 602 on the drawer-release lever 596 so that the hook 598 of the latter is prevented from seizing the coupler and the drawer may therefore be kept open instead of having to be closed between operations in order to free the coupler. In position (3), the parts are as shown, and the drawer latch 605 normally supports and is retained by the lever 596 but when the coupler descends a projection 604 through a oneway pawl 599 rocks the lever 596 about its pivot 595 and allows the drawer to open. The pin 602 is now ineffective since it moves idly in a notch 621 in the plate 615. When the supervisor wishes to take totals, he moves the lever 550 still farther to the rear and thus through a cam 552 and arms 625, 627 rocks a shaft 366 counterclockwise so that an arm 629 rocks a spider latch 634 pivoted at 633 to a door 631 giving access to the totalizers. This movement of the latch releases one leg 634' from the lid 650 and another 635 from the casing so that both lid and door may be opened. The special counter lid and the printing frame are also released and the "resetting" counter is operated. In the final position of the hand-lever, in addition to the above-mentioned actions, the drawer is released by the nose 590 of the cam 588 striking the pin 620 and so rocking the lever 596. The clerk may partially rock the catch 634 by operating a lock 641 so as to withdraw the leg 634' to allow opening of the lid 650, but the movement is insufficient to disengage the catch 635. According to the Specification as open to inspection under Sect. 91 (3) (a) the reciprocating movements of the coupler are converted into rotations of the main shaft 106 by means of a double rack 654, 655 connected by pin and slot 670 with the coupler and alternately engaging a pinion 656 on the shaft. The rack is guided by a rail 658 and is thrown over at the end of the upward movement by a spring-controlled inclined buffer 678. A pawl 675 engaging a ratchet wheel 674 on the shaft ensures completion of the stroke, and a nose 673 on the coupler by entering a notch 672 in a disc 671 prevents overrunning by the shaft during the change-over of the rack. This subject-matter does not appear in the Specification as accepted.
