Patent GB-249545-A (GB)
Abstract: 249,545. National Cash Register Co., (Assignees of Shipley, B. M.). Jan. 19, 1924, [Convention date]. Cash registers with item-printing mechanism; voucher-issuing.-In a cash-register adapted for dealing with single-item and multiple-item transactions the impression hammers for recording upon the voucher or inserted slip and upon the record-strip are controlled automatically according as a multiple-item key or a single-item key or total lever is used so that either one hammer or all the hammers may be operative. The feed of the record-strip is also controlled through the hammer mechanism so that no feed occurs during the entering of the multiple-items. In the form shown in Fig. 3 the voucher 151 passes above the fixed type blocks 706 and the amount and characterizing type-wheels mounted on the rod 577 and set by the differential mechanism in the usual manner. The strip may be fed by mechanism of the kind described in Specification 248,763. The item-printing wheels are impressed by a hammer 671, Fig. 5, while the remaining wheels and the fixed type are impressed by a hammer 690 having impression blocks 702, 703, 704, 705. Both hammers are operated by spring-controlled frames pivoted at 657 and provided with arms 694 connected with levers 696 rocked by cams 699. To prevent printing of a voucher a finger lever 652 may be raised so as to rock a flanged plate 685 to engage above projections on plates 682, 763 secured to the hammers. In a total-taking operation the item-hammer 671 must be held during the first cycle and for this purpose a second flanged plate is moved by connection with the shaft 219 controlled by the totaltaking mechanism and places its flange 688 over a pin on the plate 682. When the shaft is rotated still farther at the end of the first cycle the flange clears the pin to allow the hammer to rise and subsequently be operated for the total-printing. The flange also serves to restrain the second hammer 690 during the first cycle of the total-taking and is also effective for the same purpose in multiple-item entering operations owing to the control of shaft 219 by the item key bank differential mechanism. An additional flange 750 on the plate co-operates with a pin 749 on the recordstrip impression hammer 734 to prevent impression during the entering of the multiple-items. The record-strip 149 passes in the manner shown from roll 719 to roll 721 and is fed by pawl 722 oscillated by link 724 and plate 596. Printing on bills.-In a second embodiment of the invention the machine is arranged for printing on slips placed upon a table 772, Fig. 13, the impression hammers for the slip being consequently disposed below the type and the recordstrip above the type. The impressions upon the slip are made by three hammers controlled as follows. A hammer 823 for printing the invariable matter is disabled after the first itementering operation of a multiple-item transaction and remains so until after the total-taking. For this purpose an arm 826 is rocked to seize a pin 829 on the hammer by connection with the lever 781 described in Specification 248,763. The Itemprinting hammer operates in all item-entering and total-printing operations but is restrained during the first cycle of a total-taking operation by a flanged plate 843 oscillated by a lever 809 also as described in Specification 248,763. The additional hammer 839 co-operates with the item hammer except during multiple-item registration when another flanged plate 849 secured to plate 843 comes in the path of a pin 850 carried by the hammer. All three slip-printing hammers may be disabled, as in the first embodiment, by manipulation of finger-lever 652. The spacing feed of the record-strip 149, effected by the ratchet pawl 883 is controlled by the record-strip impression hammer 868 controlled in turn by the flanged plate. The pawl is mounted on a 3-armed plate 878 pivoted at 879 and influenced by a spring 884. The feeding movement is imparted by a recking plate 794 carrying a pin 886 to engage a link 885 pivoted to one arm of the plate 878. A guided link 889 pivoted to another arm has a pin 890 to co-operate with a dog 891 fixed to the hammer 868. During the registration of multiple items the hammer is held, as described above, and consequently restrains the strip-feeding mechanism. When however the hammer is released for operation the guide surfaces 892, 893 cause a clockwise turning of the link 889 as it rises so as to clear the dog and permit free movement of the hammer.
