Abstract: 20,993. Bloch, O. Sept. 30. Receipts, checking and recording.-Lever - operated cash registers in which the setting is done by means of rotating discs with projecting finger-pieces are shown, and have means for controlling the operation of the cash drawer by the clerk's disc, a total register which is not operated for special transactions, a releasing- key, and means for actuating printing- mechanism. There are six discs 5 on the spindle 4, of which the two outer ones are for the clerk and for special transactions, and each disc has fingerpieces or keys 6 in one quadrant, printing-types 8 in the next, registeroperating pawls 9 in the third, and locking-stops 11 in the fourth. The four value discs have reversing - pins 13 for moving the customer's indicator discs 14, which are mounted on the same spindle and have the numbers upon ribbons 74 passing over rollers 75 under the window 76 which is opened by removal of the screen 40 when the operating- lever 19 is depressed. The clerk's disc, which is first operated, has an inclined plane engaging with, and swinging up, the locking-bar 15, which is supported by arms pivoted at 16, thereby freeing the value and special discs. When these have been set by bring- ing down the proper key to the fixed edge 12, the lever 19 is pressed down about its pivot 21, and its arm 27 rises, carrying with it the hook 28, which is pivoted to it at 28<1> and has an upward arm 30 and a spring 29 both engaging with the roller 31, which is also on the arm 27. The hook 28 releases the drawer by carrying up the drawer-hook 33, but when it passes through the slot 32 therein, the hook 33 falls so as to engage the drawer when returned. Simultaneously the arms 24 carry the rod 25 into locking-notches 26 in the discs, and the rods 35 swing downwards the short arms 36 of levers 36<1>, connected by a cross-bar 37, which carries the screens 40, the two spring hooks 38, one at each end, which lock with an angle-iron 51 on the locking-beam 44, and a hook 39 for each disc, which is forced in below the stopping-pawls 48 on the beam and prevents further forward motion of the discs. The locking- beam carries a number of disc-arresting blocks 46, Fig. 10, which have pins fitting in the T-shaped slot 47, and are pressed together by means of end springs. They are rounded towards the side from which the pins 11 advance, and have sufficient play in the slot to allow the operation of one disc only at a time. The movement of the arm 36 and links 41 slides the cross-bar 42 in the guides 43 out of the path of the releasing-key 55, the depression of which rotates the arm 57 about its pivot 56, and by means of the links 58 and eccentric 59 slides the locking-beam upwards, lifting the angle-iron and the arresting-blocks, whereupon the arms 36<1> are returned by a spring 77 and the discs by counterweights. Simultaneously the spring 62 brings the recessed end 65 of the lever 61 beneath the beam, whereby the stopping-pawls 48, which normally rest upon the rod 50, are sufficiently raised to prevent forward movement of the pins 11, which can, however, return freely. The return of the locking-beam with its counterweight 63 releases the lever 61. The register has detent arrangements 72, 69, 70, 71, and the whole can swing about the pivot 78 under the control of a cam on the special disc and a spring 79, so that such transactions may escape registration. The rod 22 actuates printing-mechanism 23 on the downward motion of the lever 19.
