Abstract: 164,477. Pearce, C. A. March 6, 1920. Tills; money-delivering apparatus.-In a till or change-giving device of the kind in which sets of coins or notes are arranged in separate receptacles or compartments ready for use, each set being of a total value equal to that of some coin or note for which change is required, and in which two parallel change drawers are provided with an oscillating locking-bolt so arranged that only one of the drawers may be opened at any one time, the locking-bolt being operated by the opening of either drawer, the locking-bolt 23 is connected to an indicator 27 at the front of the apparatus showing the value of each of the sets of change in the drawer which is opened. The indicator may be in the form of a semi-circular plate 27 marked at opposite ends with the value of the change-sets in the respective drawers, and provided with a pivoted tail-piece 26 engaged by a fcrk 29 on the locking-bolt 23. The bolt is of such a size and shape that when one side of it bears on a metal plate 39 secured to one of the drawers, the other side is fully engaged with a recess 36 in a corresponding plate on the other drawer, so that the second drawer is held closed, and vice versa. A spring-controlled lever 32, having a tooth which engages in notches 25 in the bolt, prevents the latter from being shaken out of engagement with the notch 36 or 38. Each drawer is preferably divided into compartments by partitions 6, 7, and each compartment contains a change receptacle having a lower chamber 74, Fig. 7, open at the front, for the change and an upper chamber 76 open at the back for the reception of the note or coin which has been changed. A cross-bar 78 is preferably provided to facilitate the handling of the receptacle. Each drawer is urged towards its open position by a spring 40, Fig. 2, but is held closed by a locking device which is released by pressing a button 62, 63 on a cranked rod 64 at the corresponding side of the machine. The looking device consists of a pivoted spring-controlled catch lever 56 which engages with a lever 54 pivoted on an angle bracket 41 at the back of the drawer casing. The lever 54 is held in the locking position by a stop 44, Figs. 2 and 4, on a pivoted arm 43 also mounted on the angle bracket 41 and held by a spring 45 in the raised or operative position. When one of the buttons 62, 63 is pressed inwards, the inclined end of the rod 64 depresses the corresponding arm 43 and so removes the stop 44 from the path of the tail 51 of the lever 54. The spring 40 then pushes the drawer open, the lever 54 swinging so that it becomes disengaged from the catch lever 56. On the release of the button 62, 63, the stop 44 is raised by the spring 45 to its operative position, the lever 54 having previously been returned by the spring 48 into position to re-engage the catch lever when the drawer is closed. A hammer 53 may be secured to the lever 54 and arranged to strike a bell 52 on the return stroke of the lever. Runners 67 on the sides of the drawer run on rollers 21, 22 at the sides of the indicator box and on rollers 68 at the sides of the casing. A lining plate 69 at each side of the casing has inturned flanges 70 which engage with projections 71 on a sliding plate 72 at the back of the drawer to prevent the latter from being accidentally withdrawn from the casing. The plate 72 may bo slid inwardly against the action of a spring when the drawer is to be completely withdrawn.
