Patent GB-208705-A (GB)
Abstract: 208,705. Shipley, B. M. Dec. 21, 1922, [Convention date,]. Hammer-impression arrangements.-In a cash register adapted to print the items and their total on a voucher subsequently issued, separate impression hammers are provided and are controlled so that one only is effective during item-registering operations and all are operative in the total-taking operation. Moreover, when the voucher-issuing mechanism is disabled, as described in Specification 220,643, all the hammers are automatically rendered inoperative. The items, nature of transaction, consecutive number, date and customer's total are printed upon a voucher-strip 550, Fig. 6, and the total and nature of transaction are printed upon a record-strip 551 by means of a set of type-wheels 562 adjusted by the differential mechanism and by a set of type-wheels 646 turned by automatic numbering and external datesetting mechanisms, Fig. 4. The consecutive number printing-wheel is actuated at each voucher-issuing operation by means of a pawl-carrying frame attached to a plate 663, Fig. 4, connected by a link 665 with another rocking plate 667. A link 669 'depending from the pin 666 has a stud 670 engaging a notch in the link 597, Fig. 6, which conveys the rocking movements of the main cam-operated lever 570 to the linespacing feed mechanism 758 of the record-strip roll. When a voucher is not issued, the actuation of the consecutive number wheels must be prevented, and this is achieved by connecting the link 669 by another link 675 and a rock-plate 674 with the lower feed roller 581. When this roller is lowered to prevent the voucher-feed, the link 669 is swung to the right to break the driving connection at 670. There are three impression hammers arranged in series, but all pivoted on a rod 687, Fig. 6. The hammer 703 impresses on the item wheels 562, the hammer 704 prints invariable matter and the upper digits of a total. and the hammer 705 prints the date and consecutive number. Each hammer is connected bv a spring 706 to a rod 691 forming one cross-member of an operating frame 688 rockable about the rod 687. A depending arm 692 of this frame is pin-and-slot connected to a lever, controlled by a spring and provided with a roller and nose co-operating with a cam rotated from the main shaft. When items are being registered, the hammer 703 only is operated, the other hammers being held from rocking. For this purpose, hammer 704 carries a plate 711. a pin 712 on which is. during item-registration, beneath a flange 713. on a rocking plate 714. When a total is being taken, however, the two-cycle mechanism such as that described in Specification 8119/15, [Class 106 (i), Calculating &c.], rocks the flange 713 away from pin 712 and thus frees the hammer. The third hammer. 705, is controlled by hammer 704 through a pin 709, so that the one means controls the two hammers. The item hammer 703 is also controlled in totaltaking operations to prevent impression during the first cycle of operation of the machine, this result being effected by a similar arrangement of pin and flange, the latter being on a plate secured to the plate 714. All the hammers are disabled when the voucher-feed is prevented, owing to a flange 721 on plate 674, Fig. 4, taking over shoulders on the plates 711 on the. hammers 703, 704 when the feed roller 581 is lowered to ineffective position. The hammer 764 for impressing the totals upon the record-strip 551 is operated by spring and cam mechanism similar to that used for rocking the frame 688. but is held during item-registering by a second flange 777 on the plate 714. Ink-ribbon mechanism.-The Specification as open to inspection under Sect. 91 (3) (a) also contains the following subject-matter, which is not described in the Specification as accepted. The ribbon 730, Fig. 6, passes around guide and tension rollers 731, 734, and is fed forward intermittently by a pawl 737 mounted on a lever 738 rocked by pinion and sector gearing 741, spring- controlled link 744, pin 745, lever 570 and cam mechanism from the shaft 99. The lever 738 has an arm 747 in the plane of a stop shoulder 748 on a swing frame 749 pivoted at 735. When the ribbon seam approaches either amount-printing line, a button 751 on the ribbon displaces the frame so that the feed-pawl 737 can have a longer stroke to feed the seam beyond the impression line.
