摘要： 6221. Johnson, J. M. March 16. Coins, separating. - A machine for sorting Coins from bulk is provided with counters for each denomination of coin, which counters may either count the total number of such coins of each denomination sorted, or may be set to count serially a desired number for the purpose of enabling the coins to be delivered in packages. The coin-separating mechanism, Figs. 1 and 3, consists of a plate C provided at the top with slots of increasing width, the first being just wide enough for the smallest coin, from which slots lead coin channels c ... c for the respective denominations of coins. This plate is mounted on the arm A and is centrally bored to receive the driving-shaft C of a disk D which lies above it. The disk D has secured to it a thin plate d provided with a series of apertures as shown, the plate being reduced in thickness at the rear edge and from the forward edge along the bottom of each aperture to approximately the thickness of the thinnest coin, so that only one coin shall be lifted thereby, the apertures being large enough to receive the largest coin. A hopper D', which may be replaced by three troughs, one for each ring of apertures, extends over the bottom half and up on the left side of the disk, where an extension d of the hopper is bolted to the plate c‹. The remainder of the plate d is covered by a closefitting plate D to act as a stripper. The plate D is revolved clockwise to cause the coins to be drawn round in the apertures until they fall through the slots into their respective tubes by a motor B, which drives a shaft B through friction gearing b, b , which shaft drives a shaft E by worm gearing, the motion of the shaft E being communicated to a shaft E' by a twospeed gear consisting of gears e , e and complemental gears mounted on a sleeve splined on the shaft E and moved laterally by a lever e . The shaft E' drives the shaft E in the arm A , which by bevel gearing e, c drives the shaft C of the plate D. The coins from the chutes fall into a series of counting-heads F ... F arranged on an inclined base-plate so as to lie at rightangles to the separator, and each head overlaps the one on its right. The bed-plates f , Fig. 6, of these heads have rims f provided with inwardly inclined plates to form hoppers f for the coins, which thereby fall on to the coinwheels f , which have teeth f , as shown, of sufficient depth to allow the coin delivered thereto to project beyond the hooked end of the tooth. These wheels are mounted on shafts f , Fig. 10, which are driven bv bevel gearing from the shaft E , Fig. 1, chain-driven from the shaft E . Between the wheels f and the overlap of the plates f is placed a separating-plate f , which has a bevelled edge and acts as a stripper for the coin-wheels. Near the discharge aperture g, Fig. 10, each bed f has an extension G, through which passes a counting-shaft G , and on the extension is a detent H slotted to receive the shaft and carrying a pin h, the detent being on the level of the coin-wheel, against which it is normally held by a spring h , Fig. 11. An escapement wheel H is secured to the shaft G above the detent H, and carries on its underside ten teeth h , between which the detent normally projects to lock the shaft G, which operates a register M of any suitable kind through bevel gearing g , m. A coin carried round on a wheel f presses the detent outwards, releasing the wheel, and then pressing against a tooth of the wheel H to turn it one-tenth of a revolution, which is registered on the register M. The coin then passes through the discharge aperture, and the detent returns again to lock the wheel H . Each denomination thus registers on its register M, and the separate totals are shown. The shaft G extends through the housing I and is slotted at its end, the bottom of the slot having a groove g . A spring k supports a cap K provided with a pin k extending therethrough and through the slot, and with an end enlargement forming a friction wheel k having a downturned flange. A finger k , Fig. 12, above the wheel projects over the flange. A shaft L parallel to the shaft G' carries two wheels L', l bolted together and having alternately placed rounded teeth, two of the teeth of the lower wheel being normally in contact with the flange of the pulley k , a spring l in a cavity in the upper one l normally holding the stop l on the wheel L against a stop on the shaft. Rigidly secured to these two wheels is a dial L having notches corresponding to teeth of the wheel L , such notches being numbered 10, 20 ... 100, and a space of twice the usual distance being left between the first and last notches. The upper end of the shaft L carries a nut l flanged to afford a stop for a spring l , which bears against the flange of a sleeve L to press it on to the dial L , this sleeve having an arm l with a finger l capable of engagement with the dial notches, and which also serves as a stop by engaging the cap K. In counting the coins in bulk, the cap K is pressed down to engage the pin k in the groove g , thus bringing the finger k out of engagement with the wheels L , l and cutting out the stop mechanism. When it is desired to count serially, the finger k is returned to engage the wheel l , the dial being in the normal position as shown in Fig. 13. The finger l is then engaged in the notch corresponding to the number it is desired to count serially, so that each revolution of the finger k , corresponding to the passage of the coins, will turn the dial one step, the flange of the disk k' for this purpose being omitted beneath the finger. When the shaft has revolved the requisite number of times, the arm l contacts with the head K and locks the mechanism. The dial may be returned to normal by depressing the finger k , while the registers M may be reset to zero by pulling the detent H out of engagement by means of the pin h and rotating the shaft G' by hand. The coins may be delivered into separate bags or may be collected and packed as serially counted, either mechanically or by hand, while for counting coins of one denomination the coins may be placed direct into the trays, the sorting-apparatus being put out of gear by the lever e .
