Abstract: 27,767. Haddan, R., [National Cash Register Co.]. Dec. 2. Cash registers with operating - means and money - manipulating apparatus. - In a machine combined with a change-giving mechanism, the purchase price and the amount of change required are set on two groups of keys, and a clerk's handle is positioned. The operation of the crank thereupon opens the clerk's till, actuates the clerk's amount counters, prints his distinguishing letter and the two sums of money, and discharges the required change from a series of coin tubes. Depression of keys in the two groups of keys 6, 6<a> representing sales and change respectively causes differential movements of the segments 4 upon operation of the machine, and these movements are transmitted to the indicators 8, and the printing- segments 15, and also in the case of the sales keys 6 to the grand totalizer 11. The clerk's lever 18, when positioned, sets by means of a rack 20 the reel carrying the amount counters for the various clerks and also the type for printing the clerk's distinguishing letter. The money tendered is placed upon a flap 41 giving access to the clerk's own till 43, and a latch 37 normally holding this flap is withdrawn by means of one of a number of staggered pins on a shaft 32 set by the rack 20. The flap cannot fall, however, until a second latch 44 is also withdrawn, this taking place during the operation of the machine by means of a finger 46 on a shaft 47 connected with the main shaft 1. The flap is raised again at the end of the operation by an arm 52 on a shaft 51 connected with the shaft 47. The change is delivered from a series of coin tubes 56 by apertured spring-controlled slides 58 held normally by a number of latches 68, which are spring-held on a rod 69 and further supported by a shaft 72 vertically movable by cams 75. The latches to be moved to release the coin-ejecting slides are selected by cams on transverse spindles 79, 80, 81, which are connected by gearing with toothed extensions 88 of the differential segments 4 appertaining to the change-controlling banks of keys. The cams co-operate with lugs on the latches 68 so that when the shaft 72 is raised, during operation, certain lugs engage the cams and so cause the corresponding latches to rock and release the slides. If a cam is not turned the lug enters a recess in it and the latch merely rocks about the rod 69. To prevent the ejection of the change until the operation of the register is complete, a bell - crank 95 controlled by a slide 99 is projected into the path of lugs 64 on the released slides and so holds them until, at the end of the operation, the slide 99 is pushed forward again by a cam 102 to rock the bell-crank and finally release the slides. The slides arc returned to their latched positions at the next operation of the machine by means of the engagement with the depending arms 89 of a plate 90 connected with the rock-shaft 51. Specifications 9400/97, 2943/01, and 1408/04 are referred to, with regard to the type of cash register.
