This invention relates to improvements? 4in change making machines, that is'to say a machine for delivering a plurality of coins of a l given denomination when a coil of higher Vdenomination is inserted into the machine. In the particular embodiment herein disclosed the machine delivers ve nickels when a quarter is inserted, but it may be adapted to changing two nickels for a dime, live pennies for a nickel, ten pennies for a dime, etc. The present application is a substitute for my prior application Serial' No. 216,712, led June 30, 1938. Y

One of the objects of the invention is the provision of a machine of the -Icharacter stated'which shall be relatively simple and yet capable ofv functioning accurately at every operation.

Another object is the provision of'simple and eiective means for returning to the customer coins of a wrong denomination which may be inserted into the machine and for preventing the introduction of any coin into the machine while the path to the coinbox is open, or vwhen-the magazine in which'are storedthe coins to be delivered contains less than apredetermined minimum number of coins.

Other objects and features of novelty will appear as I proceed with the description of that embodiment of the invention which, for the purposes of the present application, I have-illustrated in the accompanying drawings, in which Y Fig. l is a front elevational view of a machine embodying the invention.

In the drawings, wherein a single 'unit machine is illustrated, I2 is the base of a casing or cabinet in which the mechanism is housed. This casing comprises sides I3, a front wall I 4, and

a top I5 secured together by suitable means. 'The back I 6 of the casing'is preferably hinged at 'one' side as'lby hinges I1, the other side being fas'- tened by a lock indicated at Ila. In' this man-y ner the interior of the casing is made conveniently accessible.

On the base behind the front wall there is mounted a transversely extending angle iron I8 which assists in supporting another angle iron IS that extends across the casing directly behind the front wall thereof, the horizontal leg of this upper angle iron forming a shelf lupon which are carried certain parts of the mechanism. The vertical legs of the angles I8 and I9 are cut away at certain points to provide clearance for coin discharge chutes, as will appear hereinafter, and these vertical legs are fastened together and .to the front wall of the casing by means of bolts 20.

On the shelf formed by the horizontal part of angle I9 I mount a shallow box 2I which forms a guide for a flat slide 22 whichY is slightly'less in thickness than the height of the group of coins which it is the function of the machine to deliver at one operation, in this case ve nickels. To the rear end of this slide there is attached a rod 23 with a ball socket 24 o n its rearmost extremity. A coil spring 25 surrounding the rod and bearing at one end against the box 2| `and at the other against the ball socket 24, tends to hold slide 22 in its rearmost position.

In the top of the box 2I there is a countersunk opening in which is received the lower 'end of a coin tube 26 which constitutes the magazine of the machine wherein are stored'the nickels or otherr coins to be deliveredto the customer. This tube is conveniently made. intwo pieces, as indi.-V

cated in Fig. 7, so that slots 21 and 28 are provided front and rear running the entire length of the magazine. In the slide 22 there is a round hole 26 which in the rearmost position of the slide registers with the interior of the magazine, and is normally filled with coins that descend into it by gravity from the magazine. The two parts of the magazine are supported intermediate their ends by brackets 30 and 3| secured to the front wall of the casing. These brackets have curved surfaces fitting the curved surfaces of the magazine, to which they may be welded or soldered if desired.

The ball socket 24 is adapted to be engaged by a ball 32 at the free end of a link 33 that is pivoted at one end of a lever 34. This lever is arranged to be operated by a plunger 35 which is rectangular in section, and which is pivotally connected with lever 34 near the middle of the latter, and is mounted to slide in bearing blocks 36 that are secured to the top of angle I9. The other end of lever 34 is provided with a slot 31 which receives a pivot carried by the bifurcated rear end of a pin 38 that is mounted to slide in the bore of a barrel 39 which forms an integral part of a bracket 46. This bracket has a front cover plate 58 that is provided with an ear 4! which extends beneath and is suitably secured to the horizontal leg of angle |9. A coil spring 42 urges pin 38 rearwardly, its rearward movement being restrained by its connection with lever 34. One side of barrel 39 is flattened in order to have fastened thereto a at bar 43, the end of which is formed to t within a notch 44 formed in the forward edge of lever 34.

A knob 45 is pinned to the forward end of plunger 35 outside the casing, A person operating the machine grasps this knob and pulls the plunger forward against the action of a coil spring 46 which bears at one end against the forward guide block 36 and at the other end against a collar 41 pinned to the plunger. In some cases the spring 46 may be omitted, springs 25 and 42 being sufficient to insure proper functioning of the mechanism.

A coin chute 48 for the reception of the coins of higher denomination for which change is desired, that is quarters in the present case, is suitably supported at its upper end by the front wall I4 of the casing and projects into a slot in that wall and into communication with a slotted plate 49 screwed or otherwise attached to the wall. The lower end of this chute terminates at and is attached to bracket 4B which, with the cover plate 58, constitutes a continuation of the coin chute. In bracket 4D two fingers 5| are hung upon pivots at their upper ends, their lower ends being urged inwardly or toward each other by V-shaped springs 52. The sides of these fingers which face each other are formed with ribs 53 that define front and rear grooves in the fine gers. The front grooves are aligned with the interior of the coin chute 48, and at their lower ends are provided with bevels 54 which serve to support a coin, illustrated at C, see particularly Fig. 5. The rear grooves also terminate at their lower ends in bevels 55 which form wedge surfaces that are adapted to be engaged by similar surfaces on the lower end of a wedge plate 56 that slides in the grooves behind ribs 53. When this wedge plate is caused to descend below its normal position it swings the-arms outwardly against the action of springs 52, thereby spreading the bevels 54 apart and releasing the coin then being supported, permitting it to fall from the supported position indicated in Fig. 5. A vertical slot 51 is formed in the plate 56, into which a reduced end of pin 38 extends, If this pin is drawn forward at a time when there is a coin C supported by the fingers 5|, the coin forms a stop preventing further travel of the pin 38 in a forward direction. When there is no coin thus supported by the fingers 5| the pin is free to travel further in a forward direction, a perforation 58 being formed in the cover plate 50 to clear the pin.

In laterally projecting ears 59 and 59 on bracket 40 there is mounted a slide bar 60, A collar 6| pinned to this bar forms an upper abutment for a coil spring 62 which bears at its lower end against ear 59. Collar 6| also limits the upward travel of the slide bar resulting from the pressure of spring 62. The bar 6U terminates at its upper end in a head 63, the upper surface of which is beveled downwardly toward the front. In this head there is mounted one end of a bent rod 64, the opposite end of which is welded or otherwise attached to Wedge Vplate 56. Hence when the rod 68 is depressed the wedge plate 56 moves downwardly to the same extent.

On the plunger 35 there is secured an upwardly extending Iarm 65 which supports a pivot pin 66 from which hangs a bifurcated pawl 61. Between the bifurcations of this pawl there is mounted a roller 68. Pawl 61 is free to swing rearwardly, but forward motion is prevented by an extension 69 on the arm 65. Hence when the plunger 35 is pulled forwardly from its normal position illustrated in Figs. 2, 3, 4 and 6 of the drawings, roller 68 engages the rear surface of head 63, swinging the pawl 61 rearwardly far enough to enable it to ride over the top of the head. Its motion in this direction is limited however by a resilient stop 69a of watch-spring metal as illustrated particularly in Fig. l2. On the return stroke however the roller engages the bevel surface on the forward side of the head and pushes it downwardly momentarily. It will be observed that the beveled upper surface on head 63 is held against turning by the attachment of the slide bar 68 to the wedge plate 56.

Bracket 40 includes downwardly projecting extensions 10 at the lower ends of which there is mounted upon a pivot 1|' a gate 1| that is normally drawn toward a rear position, illustrated in Figs, 2 and 3, by a coil spring 12. A bent arm 13 welded or otherwise secured to gate 1| extends around to a position near and in front of slide bar 60, and on the latter bar there is secured a finger 14 which engages arm 13 when the slide bar is depressed, and thereby swings gate 1| forwardly against the action of spring 12. When the gate is in the position illustrated in the drawings any coin which descends through chute 48 and is not caught by fingers 5|, as for instance coins smaller than a quarter, is deflected by gate 1| away from a coin box 15 and into a discharge chute 16 leading to an elongated cup 11 in front of the casing, from which it may be removed by the customer. On the other hand, when the gate 1| is swung forwardly by the pressure of finger 14 on bent arm 13, as it is when the fingers 5| are in the coin releasing position, the coin which then drops from those fingers is deflected into the box 15.

The depression of the slide bar 60 performs a third operation, namely it closes the upper end of coin chute 48, thereby preventing the introduction of a coin into the chute while the gate 1| is in its forward position, so that it is impossible 'for a'user' to 'putawrong coin into 'the machine and'have it go into the box 15 instead of being deflected and discharged into the cup T1. For this purpose I provide a clamp'18 pinned to the lower extremity of a rod '|9 and attached to the lower end of slide bar 68. Rod T9 is suitably guided for vertical movement along the front wall I4 of the casing. At its upper end this rod has a short horizontal portion bent to provide a horizontal eye 88 which surrounds'a short vertically arranged rod 8|, guided by brackets 8 la for vertical movement and normally supported by a coilspring 82 which engages beneath a collar 83 -pinned to the rod. The lower end of rod 8| normally stands just above chute 48, but the upper wall of that chute has an opening 84 therethrough which is adapted to receive the rod when it is depressed. AWhen so depressed the rod obviously forms a barrier preventing the introduction ofa coin into the chute.

When a coin is inserted into the machine and the plunger 35 is pulled forwardly as far as it will go, slide 22 is moved forwardly and the coins in the hole 29 of the slide are moved forwardly until they fall through an opening 85 into a chute 8B that also extends through theforward wall of the oasingand communicateswith the cup 11.

8i is a weight which is placed on the top of the stack of coins in the magazine 26. It is provided with an extension 88 which projects through slot 2l in the magazine and is perforated to slide upon a rod 89 that is guided near its upper end in a guide bracket 99 attached to the front wall of the casing. On its lower end it carries a collar 9|. Rod 89 has a horizontal upper portion 92 and a downwardly extending vertical portion 93 which at its lower end is turned at right angles and formed with an eye 94 that surrounds rod 8| just below eye 88. When the stack of coins in magazine 25 is so depleted that the weight 8T engages and depresses collarV 9|, rod 89, 92, 93 pushes down rod 8| and closes off chute 48. At the same time an Empty sign 95 carried by rod 93 descends into position behind a small window 96 in order to indicate to the prospective customer the reason why his quarter is rejected.

Operation-Assuming that a customer wishes to change a quarter for five nickels, he inserts his quarter through the slot in plate 49. The quarter descends through chute 48 and is caught by fingers The customer then grasps knob 45 and pulls it forward. The rst result of this movement is to bring pin 38 up against the quarter, as indicated in Fig. 9, when further movement of that pin is prevented and its free extremity thereafter acts as a fulcrum for lever 34. Continued movement of the plunger forward brings ball 32 into engagement with socket 34 and then causes rod 23 to move forward, pushing slide 22 forward with its charge of five nickels which are dumped through opening 85 into chute 86 and delivered to the customer. During the forward movement of the plunger roller 68 swings pawl 8'! rearwardly and rides over the top of slide bar Eil. The customer then releases his hold upon the knob 45 and springs 45, 25 and 42 act to return the parts to normal position. During this return movement roller 68 engages the beveled face on the head 53 of slide bar 60 and depresses that bar by cam action. Its rst effect is to close the coin chute 48. It then swings gate 7| forwardly and thereafter spreads fingers 5| releasing coin C, when the latter drops, striking the gate and being deflected into box 15.
