As shown on the drawings:

The reference numeral 1, indicates a box or casing having an opening 2, formed in the. lower rear portion of one of the end walls thereof. The casing 1, is supported on legs 3, and has rigidly mounted on the inner surface of the front wall an inclined.

trough, hopper or chute 4, which slants downwardly and rearwardly to permit the lower or discharge end 5, thereof to project through the opening 2, and curve rearwardly with the open end thereof disposed above a coin receiver or cup 6, supported to the rear and toward one side of the casing. As clearly shown in Figs. 2 and 3, the rear wall of the casing 1, is higher than the front wall. The side walls of the casing are each cut or formed with a long inclined edge 7, the lower end of which joins the lower end of a short inclined edge 8, which is disposed at right angles to the longer edge 7 to afford suitable seats to receive a coin holder and ejecting mechanism seated there in in inclined position.

The coin holder comprises a rack bent or formed tp provide a plurality of parallel semi-cylindrical coin holding chutes, tubes or feed troughs numbered 9, 10, ll, 12 and 13, open at both ends and of diflercnt sizes to hold coins of different denominations.

The tube .is adapted to receive pennies stacked therein, while the tube 10, is for clined position to close the top of the casing 1, with the upper rear end of the holder resting upon the upper edge of the rear wall of the casing, Integrally formed on the back of the coin holder are apertured lugs or arms 14;, which are secured to the inner sur faces of the side walls of the casing l, by

means of screws 15, or other suitable means. A metal plate, strap or base plate 16, projects across the bottom of the coin holder, and has the ends thereof bent upwardly at right angles to form flanges 17, which are rigidly secured to the lower end portions of the sides ofthe coin holder. The base plate 16, rests against the upper edge of the front wall and projects into the casing, and has the inner margin thereof cut away to afford semi-circular discharge openings 18, of different. sizes corresponding to the sizes of the respective coin tubes. The discharge openings 18', extend to about half the depth of the coin tubes to permit the lowermost coin in each tube to seat on the solid portion of said base plate.

Each coin tube is provided with a selective ejecting mechanism adapted to, permit the ejection of one or more coins of the same denomination from each of said tubes as desired The ejecting mechanisms for the various tubes are practically the same with the ss rt on th t h tub 9 nd are equipped with four ejectors, while the tubes 11, 12and13 are arranged with two ejectors. The number of ejectors for each tube, however, may be increased or decreased as desired. Due to, the similarity in construction of the ejecting mechanisms, that for tube 9,

will be described and the respective reference numerals will be applied to corresponding parts for the ejecting mechanisms of the other tubes, The ejecting mechanism compri'ses ei ee pl t 0, 2 d

posed one above the other in the order named and all projecting through an opening 23, provided for the purpose in the lower portion of the tube 9, directly above the base plate 16. Each of the ejector plates for tubes 9 and 10, only has a portion thereof at one of the front corners cut away as denoted by the reference numeral 2 1, to afford a clearance for the proper operation of the ejectors as hereinafter more clearly described.

Each ejector plate has the longitudinal margins thereof bent upwardly at right angles to provide guide flanges 25, which extend from the front end of the ejector plate to within a short distance of the rear end thereof, and acts to support the ejector plate disposed thereabove. The ejector plates are each provided with a longitudinal slot 26, in

the front portion thereof. Said slots register with one another and projecting downwardly therethrough is a guide pin 27, the lower end of whichis rigidly secured to the base plate 16, by means of a rivet or screw 28. coin opening or pocket 29, is provided in each of the ejector plates of a diameter sufficient to permit the respective coins to seat therein with the lowermost coin in the tube 9, resting upon the base plate 16. Mounted or secured upon the front projecting end of the ejector plates 19, 20, 21 and 22, are keys or buttons 30, 3,1, 32 and 33, respectively, numbered or labeled 1, 2, 3 and 4, to correspond to the number of coins said buttons are adapted to eject when operated. Integrally formed centrally on the inner or rear end of each of the ejector plates is a pair of parallel arms, forks or prongs 34, separated from each other by a guide slot 35, open at the rear end.

Rigidly secured across the upper portion of the back of the coin holder by means of screws 86, is a mounting plate 37, to which is rigidly secured a plurality of yoked brackets having apertured lugs or arms 38, one bracket being disposed at the back of each of the coin tubes. Supported by said lugs 38, is a. rod or shaft 39, upon which is rotatably mounted a plurality of levers 40, one for each of the coin tubes. Each of the levers 40, has the upper end thereof yoked or U-shaped, as denoted by the reference numeral 41, to permit the same to be engaged on the shaft 39, between a pair of the lugs 38, to hold the lever in proper position. The lower end of each lever 40, projects downwardly through the slots 35, be tween the prongs 34 of the ejector plates, of the respective coin tubes, and is held pressed against the inner ends of the ejector plates to normally hold the same extended, by means of a main spring 42, engaged around the shaft 39, with one end engaged against the mounting plate 37,, and with the other or lower end engaged around the rear edge of the respective lever 40. Engaged on the shaft 39, adjacent one ofthe lugs 38,

of each of the yoked brackets are second 1 rear end of each of the ejector plates 19,

is a foot orarm 45, which projects upwardly to engage behind the rear end of the respective ejector plates '20. Formed on the rear end of each of the ejector plates 21, is an upwardly projecting foot or arm 46, the

upper end of which is bent outwardly and provided with a notch to receive the lower end of an actuatingspring 47, which is engaged around the shaft 39, and has the upper lendbearing against the mounting plate 37. Secured or formed on the rear end of each of the ejector plates 22, is an upwardly projecting foot orarm 48, the upper end ofwhichis bent outwardly and notched to a receive the lower end of a spring 49, which is engaged around the shaft 39, and has the upper end bearing against the mounting plate 37, i a

The operation is as follows:

With the parts assembled as shown and described pennies, nickels, dimes, quarters and half dollars, are manually stacked in the respective coin tubes 9, 10, 11, 12 and 13. Normally the ejector plates are held projected forwardly by their respective springs so that the coin openings 29, register or are disposed below the coin tubes to permit the lowermost coins to seat in said openings one above the other with the lowermost coin in each stack resting upon the base plate 16. i

To cause ejection of a single penny from the tube 9, the key or button 30, designated 1, is pressed downwardly toward the coin holder, thereby sliding the ejector plate 19, inwardly beneath the respective ejector plates 20, into a position wherein the outer end of the slot 26, is engaged against the guide pin 27 to limit the inward movement of said ejector plate 19. With the movement of the ejector plate 19, the lowermost coin in the tube 9, which is seated in the opening 29, of said ejector plate, is carried thereby into a position wherein the opening 29, registers with the opening 18, formed in the base plate 16. The coin falls by gravity through the opening 18, into the chute 4, within the casing 1, and slides downwardly therein and is discharged into the receiving cup 6. Upon release of the button 30, the respective lever 40, under the stressed action of its spring 42, acts automatically to return said ejector plate 19, to its normal position.

If it is desired to eject two pennies from the tube 9, the button 31, associated with said tube, is depressed, thereby forcing the ejector plate 20, inwardly together with the ejector plate 19, disposed therebelow and having the foot 45, thereof projecting upwardly behind the rear end of said ejector plate 20. The simultaneous movement of both of the ejector plates 19 and 20, inwardly carries the two lowermost coins into a position wherein they drop by gravity through the opening 18, into the chute 4, to be discharged into the cup 6. Release of the button 31, permits the s rings 42 and 43, through the lever 40 an the foot 44, to automatically return the ejector plates 19 and 20, to normal position, thereby permitting the coins in the tube 9, to move downwardly through the registering openings 29. Three and four pennies may be discharged from the tube 9, by deprewing the respective buttons 32 and 33, thereby causing simultaneous inward movement of the ejector plates 19, 20 and 21, or 19, 20, 21 and 22, depending upon the button depressed. The inward movement of said ejector plates permits the coins seated in the openings 29, thereof to fall through the opening 18, to be discharged into the cup 6. The arrangement of the various feet 44, 45 and 46, of the ejector plates 20, 19 and 21, respectively, permits the selective operation of said ejector plates to be made to afford a means whereby the ejection of any desired number of coins from the coin tube 9, may be efi'ected.

In a similar manner, one or any selective number of coins can be ejected from any of the coin tubes 10, 11, 12 and 13, by depressing the proper keys or buttons associated with said tubes, whereby coins of different denominations may be ejected as required.

The compact arrangement of the coin holder ejecting mechanisms, permits any desired selective combination of keys or buttons associated with the various coin tubes to be made by one hand of an operator with a single operation to cause the ejection of the required number of coins from the respective coin tubes to" make a desired amount of change. To change a dollar the buttons 30, of the coin tubes 10, 12 and 13, together with the button 31, of coin tube 11, are simultaneously depressed by the fingers of one hand of an operator, thereby causing the ejection of a nickel, a quarter, a half dollar and two dimes, into the cup 6. In like man nor any desired amount of change may be made by a selective operation of the ejector buttons. It will of course be understood that the coin tubes may be equipped with any desired number of ejectors, other than the number herein shown and described. It is never necessary to depress more than one button of a particular coin tube at the same sired ruse ected change combination may be made by a single operation of one hand of anoperator, since there Will not be more than five button depressions required at a single time.-

l The levers 40, due to the action of the master springs 42, act to automatically return the variousejector plates, which have been depressed, to normal position, while the auxiliary springs 43., 47 and 49, associated with the respective ejector plates 20, 21 and 22', respectively, assist in the return of-the ejector plates when two or more ejector plates of a cointube are depressed at one time. Thecoins of the different denominations disposed in the various coin tubes, automatically feed downwardly as the lowermost coins are ejected, as soon as the ejector platesare returned to normal position after an ejecting operation. The inward and outward-movements of the ejector plates is limited by the guide pins 27, engaged in the slots 26. i 7

'Where three or more ejecting plates are associated with a single coin tube, the plates may be cut away, as denoted by the reference numeral 24, to permit a selective operation of said plates by the buttons attached thereto. 7

We are aware that numerous details of construction may be varied through a wide range Without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

We claim as our invention:

1, A selective change maker (omprising a, coin tube for holding a stack of coins of the samedencmination, a plurality of superimposed apertured ejectors slidably disposed therebelow and adapted to receive the lowermost coins in said tube seated therein, means on said ejectors for selectively operating the same to cause the e'ection of one or more coins from said tube y a single operation of one of said means, a shaft mounted on the back of said coin tube, a lever pivoted there on and engaging said ejectors, a main spring mounted on said shaft for automatically returning the ejectors to normal position after the same have been operated, and auxiliary springs on said shaft and engaging a number of said ejectors to assist in returning the same to normal position.
