out of sheet metal and provided with'a' finger. piece or key ll). The lever is formed with an angular projection providing a member or plate 41 which is substantially parallel with the body of the lever. The

lever is mounted .on a rod L2 which is fitted in openings in the end walls 43, ll of the lower casing member. The rod passes through the spacing plate 4:1 as well as through the main portion of the lever. In this manner the lever has a double bearing on the rod which prevents it from wabbling even though it is made of relatively thin metal. The lever 39 is in the form of a bell crank having a short arm 45 which has a rotative and slidable engagement with a lever 46 fulcrumed on a rod l7 which latter is mounted in the casing member 25 below rod 42. The lever to is also preferably formed with an angular projection 4:8 similar to the angular projection4l of the lever 39 and serving the same purpose. The lever 46 extends around and above the lever 39 and terminatesin a rounded end H) which projects through a slot 50 in the coin ejecting slide-3S. The engagement between the short arm of lever 46 is shorter than the thereof. The rounded end of the short arm 45 0f the manipulating lever 39 can slide as well as rotate between the lugs 51,' this being necessary in view of the diiferen'ce in radius between the engaging arms.

The coin ejecting slide 3S is formed with down turned flanges 52 which lie in'slots formed in the base plate 32. The base plate is also formed with a slot 54 between slots 53 through whichthe end of lever {LG-ex- The lever 46 is formed with a projection 55 connected to a helical spring 56. The other end of the spring is anchored to a rod 57 which is bound against a rib 5S 7 on the under side of the base plate by means of cotter pins 59.

. The several units constructed as above described are arranged side by side with the spacing projection of each lever bearing against the body portion of the adjacent lever. The end levers are preferablyheld in proper position by spacingsleeves 60, 61.

'In order that twenty cents in change be ejected by a single operation I haveprovided the machine with two ten;cent coin pockets 34 3t". Thecoin ejecting slide 38, forming a part of a coin ejecting unit, the key 40 of which is marked 10,- is moved, when key 40 is depressed independently of the mechanism that ejects coins from the other ten cent pocket 31".- The .38 ejects a coin'from pocket 34?, andat the same time slide 3S is moved to eject a coin from the pocket 34.

The manipulating levers 39 extend through slots 64 in the front plate 26. 3 The length of these slots is such that the levers 39 cannot be depressed far enough to throw the corresponding slide engaging levers into such position that the latter will not be automatically returned by springs 56 to their normal positions when the pressure ofthe fingers is taken from the keys.

The coins ejected from the coin pockets are pushedoverthe rear marginal edge of base plate 32 and fall into an inclined receiving chute 65. This chute is made of sheet metal. preferably, and is'reinovably arranged within thelower casing member 25 with its delivery end communicating with an opening (36 in the end wall ie of the casing. In fact, the chute requires no attachment to the casing. It has enough spring to hold it in the proper position; To the outside of the casing is attached a coin delivery chute 6 7 which is preferably formed with a bend toward the sideof themachine opposite to the side on which the keys are arranged. The end wall 44 of the casing is formed with slots 68 and the chute with hooks 69 which enter the slots.' The engagement is preferably made more firm-bya screw 70 which extends through a .lug:71 on the chute and into the end wall 44:. The receiving chute 65 is preferably formed with a lip 72 which overlaps the'delivery chute a trifle. The delivery chute is preferably provided with a cross piece 73 which stands far e'nough'above the bottom of the chute so that it intercepts any rolling coin and causes the same" to drop on its side andin that the chute. V V

The constructionof the ejectingmechanism is such that the coin is ejectedby'a manner slide the rest of the way through.

sharp, quick movementof the ejecting slide.

If the machine be properly operated the coins will be ejected-without fail. By a tion preventing the slide when actuated again from reaching the partially ejected coin. In order to straighten the stack the upper casing member is formed at the pockets with a plurality of notches 74. and the keys 38 are similarly formed on their inner ends war notches 7 5. This permits a pencil or other thin instrument to be inserted under the forward edge of the stack so as to raise it sufliciently to allow the slide to be brought against the lowermost coin or partially ejected coin.

In Fig.8 I have shown a machine, in all other respects like the machine just described, which is provided with a discharge chute 67 intended particularly for deliven ing change to pay envelops, or the like. The chute is shown as formed with hooks 69 adapted to engage the end of the casing of the machine through the slots 68, and with a screw 7 O for binding it to the casing. The intention is to have the machine furnished with two chutes of thesort above described either one of which can be usedas required.

In Fig. 9 I have shown the same machine with certain parts interchanged so that the coins will be delivered to the side of the ma chine at which the keys are located so that the change may be handled by the operator. This is the usual way in which the change ejected by change making machines is handled and while I consider that the immediate delivery of the change to the customer, or into the pay envelop as provided by the constructions previously described, Wlll be orconsiderable advantage, it may happen that under some circumstances it will bemore desirable for the person who operates the machine to collect the coins ejected by the machineand give them to the customer or make such other disposition'of the same. as the circumstance calls for. In order to modify the machine in such manner that the ejected coins can be conveniently handled by the person who operates the machine, the front plate 26 of the machine as previously described is removed, together with the receiving chute 65, and for the latter a chute 76 (Fig. 11) is substituted. The chute 7 6 is provided with a slotted lug 77 adapted for engagement with the screw 29 which holds together the rear edges of the upper and lower casing members 27, 26. At the forward end of the chute are slotted brackets 7 8 which hook over the ends of the rod l7 on which the slide engaging levers 46 are fulcrumed. A front plate 79 is substituted for the front plate 26. The coins ejected from the stacks fall into the chute 76 and are delivered to the front side of the machine, that is, to the side at which the operating keys are located.

I have shown in connection with the machine of Fig. 9 a slight modification in the construction of the coin ejecting slides which, however, could be used as well in connection with. the machines previously de-' scribed. The slide 38 (Fig. 10) has attached to the inner end thereof a bar 80 formed at its extremity with an upstanding leg 81. The bar projects from the slide a distance equal, substantially, to the diameter of the coins of the stack operated upon. The bar moves in the slot 54.- of the base plate formed for the accommodation of the end of the slide engaging lever a6. It lies, nor mally, directly under the stack of coins. If the manipulated lever 39 is given its full stroke so that the coin operated upon is completely freed from the stack of coins above it, the coin will readily fall from the bar 80 into the receiving chute. On the other hand, if the manipulated lever is not depressed sufficiently the lug 81 on the bar 80 engages the coin and returns the same to its normal position under the stack when the operating levers are returned to their positions of rest by the spring 56. By this expedient it is impossible, if a coin is partially ejected, through careless operation, for the coins above it to take an oblique position blocking the further operation of the ejecting mechanism.

Resume 07' operation. With the coin pockets filled with coins of the proper denomination, change is made by depressing the manipulated levers corresponding to the different coin stacks. The throw of the manipulated levers is relatively short. The movement of the ejecting slides 38 is, nevertheless, very rapid because of the compound lever arrangements by which the slides are operated. The engagements between the le vers 39 and the corresponding slide engag ing lev rs i6, and between the latter and the slides, are very free so that the apparatus responds to a light touch and the possibility of the parts sticking or clogging is eliminated. The coins are ejected directly into the receiving chute. The action is, therefore, simple and positive. There is no danger if the machine is properly operated that the proper coin will not be ejected at every depression of the key. The machine can be run at a high rate of speed which is particularly important perhaps when it is used for placing change in pay roll envelops. lWhen the machine is used in this connection it is preferably provided with the delivery chute 67 (Fig. 8). If the ma chine is to be used for delivering change directly to a customer. in a store or restaurant for example, the chute 67 is removed by loosening screw 78 and uuhooking the chute from slots 68 and the chute 67 is put in its place. This chute delivers the coin toward the side of the machine away from the operator, that is, the side toward the customer, so that the operator does not have to handle the coins at all.

If through careless operation a coin should not be fully; ejected, with the result that thecoins in the stack above take an oblique position blocking the further opera tion of the ejecting apparatus, this may be remedied by placing a pencil through the notch 7% in the casing and the corresponding notch 75 in the end of the slide and raising the forward'cdge oi the stack su'fliciently to allow the slide to pass and come into contact with the partially ejected coin. If the slides are constructed as shown in Fig. 10, the tilting of the stack cannot occur under such circumstances, but the provision of the slides with the projections 80 makes the ejecting action a trifle slower so that, where the highest rate of operation is desired, I prefer not to employ this feature. When it is desired to have the operator handle the change the inner or receiving chute 66 is removed, together with the'front plate 26', and a chute 7 6 (Fig. 9) which deliversthe coins to the front of the machine, under the front plate 79, is put in place of the otherchute.

While I have described my invention in certain preferred embodiments, it will b understood that further modifications might be made without departure from the principles of the invention. Therefore I do not Wish to be understood as limiting the invention to the particulars described and shown except so far as certain of the claims are specific thereon.
