Title: Improvements in Money Boxes.
Inventor: SMITH GEORGE
IPC: G07F17/10
Filed: 1918-03-21
Abstract: 124,281. Smith, G. March 21, 1918. Counters for coins.-A circular money-box is constructed with its parts capable of being so set that only a given number of coins of the same denomination may be received in it, the lid being then automatically freed for opening it, or being releasable at any time by means of a key. In the construction shown, a plate b with an upturned flange b<3> is held in the lid 1, and a coin-carrier c is mounted to turn on a flange b<2> surrounding a central hole in the plate, a lug c<1> on the carrier passing down through a hole b<5> in the plate. A push-piece o' carrying a pawl o turns on the flange b<2>, and above it is a toothed and numbered counting-disk a having a tubular axle working in the flange b<2> and carrying lugs a<2>, by which the disk may be set by hand, its numbers being visible through a window in the lid. The parts being in the position shown in Fig. 1, with the carrier engaging a stop b<6>, the box is closed by inserting the lug c' of the carrier in a small slot 1<a> of the boxbody and by pressing down the opposite side of the lid, so that a down turned catch k engages under a flange l in the body of the box; this catch, which passes through the plate b, is part of a limb g' mounted on the lid-flange b<3> and carrying a retaining-pawl g. On inserting a coin through a slot d in the lid-edge, it occupies a recess e in the carrier, and, on then turning the lid relatively to the box, the coin acts on a tail o<2> of the part o' and causes the pawl o to turn the disk a a distance of one tooth; the coin then, aided by a spring tongue n, falls through a hole b<1> in the plate b and into the box. The operation is repeated until the pawl g reaches a deep tooth of the disk a, and blocks the carrier by engaging a projection h upon it. To open the box, a key m is inserted through a hole in the lid-edge and behind the limb g<1>, so as to push the catch k free of the flange l. In a money-box with automatic release, the pawl g carries the catch k, which is thus freed when the deep tooth referred to. is reached. The pawl o may sometimes be mounted on the coin-carrier and be guided by a cam-slot so that it moves the counting-disk one tooth at a time. A shield f on the coin-carrier prevents premature insertion of coins. In some cases, the coin-carrier is operated by the tail of a lever protruded through a slit in the side of the box.
