CHANGE MAKER,

Application filed January 7, 1921.

To, all whom. it may concern:

Be it known that If, AL ERT Been, a citizen 0f; the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Change Maker; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to improvements in a type of change maker adapted to be used in. places where a great, volume of small change must be handled speedily and correctly, as in restaurants, retail stores and theatres, or in making up pay rolls and the like.

It is an object of the invention to provide a change maker adapted to afford a ready means for making change by positively ejecting the lowermost coin or coins from a stack of coins contained in tubes or holders.

It is a further object of the invention to provide a change maker which is composed. of a small number of partsv and therefore cheaper to manufacture, simpler of construction and less likely to get out of order.

Another object of the invention is to provide a change maker wherein clogging of the coins or the ejection of an incorrect number of coins is rendered impossible.

A still further object of the invention is to provide achange maker wherein the keys for ejecting the various coins are all positioned within convenient reach of the fingers of one hand of the operator, whereby the exact amount of change required can be delivered at one stroke.

Other and further important objects of this invention will be apparent from the disclosures in the specification and drawings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a front elevation of'a change maker embodying the principles of my invention.

Figure l is a front elevation of the coin ejecting levers, parts being shown in section.

Figures 5, 6 and? are views showing three. consecutive stops in the delivery of a coin by the ejecting mechanism.

Figure 8 is a view showing the coin supporting base beneath the coin holding tubes.

Figure 9 is a section taken on the line 99 of Figure 8 looking in the direction indicated by the arrows, and showing the ejector slot.

igure 10 is a, partial section taken onthe line 1010 of Figure 2.

Figure 11 is a detail view showing the method of mounting the coin supporting plate.

As shown on the drawings:

Thechange maker comprises. a base 10, having a body portion 12 supported thereon. holding tubes 14, the ejecting mechanism and the coin delivery chute l8 and has a readily demountable casing built thereon which encloses the mechanism leaving only the coin tube, the depressible ejector keys and the end of the delivery chute 18 projecting.

Any convenient number of coin holding tubes 14 may be used together with a corresponding number of ejecting keys 20. In the construction shown in the drawings, six tubes and keys are used, the largest tube being for half dollars, the one next to it for quarters, then tubes for dimes, nickels and pennies, in order. The second last tube is adapted for the delivery of two pennies at one stroke of the key and the corresponding key is marked with a 2 to indicate that two. pennies are delivered upon one stroke of that key. Obviously, three or four coins may be delivered by one stroke of any particular key if so constructed and therefore any desired combination of tubes and keys may be provided.

The principle of operation however, is exactly the same in each case whether one or more coins are ejected, and therefore only one ejecting device will be particularly described.

Figures 5, 6 and 7 best illustrate the operation of the ejecting mechanism. Con- This body portion includes the coin sidering, however, Figure Qfirst, the reference numeral'22 indicates a depressible lever on the end of which the indicator key is fixed. This lever is pivoted to the body of the device at 2%. Co-acting with the-lever 22- is a bell crank lever 26 pivoted to the body at 28 and held in operative position against the lever 22 by means of a leaf spring 30 held in place on the body by a screw 31. A roller or hearing of any sort is provided at 32 providing either a rolling or sliding Contact between the levers. As shown in- Figure 4,- the bell crank lever 26 is channel-shaped and is provided with a central slot 3 l, in which the key-lever 22 is adapted to slide. The short lower arm of the bell-crank lever 26 is provided with two upwardly extending ears 36, between which the lever 22 is positioned.

The top of the longer vertical arm of the bell-crank lever 26 is providedwith a hori- Zontally extending ledge 38 and with two in the base 60 of the coin holder. roller 46 is held against the lower side of the as maybe desired.

upwardly projecting ears 40, in which cars is mounted a shaft 4-2. Pivoted on the shaft 42 is a short bifurcated lever 44 having at its middle portion a roller 46 mounted for free movement on a shaft d8 extending across one end of the bifurcated portion of the lever. The free end of the lever e l is made in one piece and is under side with a shallow depression, into which is fitted the upper end of a helical spring 50. The lower end of this spring is mounted in a corresponding depression in the end of the horizontal ledge 38. Integral with or attached to the ledge 38 in any suitable manner, is the bracket 52 provided at its end with an upstanding lug 54, the purpose of which will be hereinafter described.

Integral with or fixed to the lever let and positioned directly above the spring 50 is an upwardly extending horn or lug 56 pointed and bent over at its upper end as shown. This horn or lug 56 is adapted to move in the slot 58 (see Figures. 8and 9) base plate 60 and the lug 56 is of such a length that when the roller i6 is in its normal springpresscd position the lug 56 will extend upwardly through the slot 58 and project above the level of thebase plate 60 to just the thickness of the coin to be ejected. Obviously this lug may be so arranged or lengthened as to eject two or more coins at. one time, as may be desired.

immediately above the base plate 60 and parallel therewith is a plate 62L This plate 62 is spaced from the plate 60 by'a distance equal to the-thickness of one or more coins, The plate 60 is cut away as shown at 64; in Figure 8 to allow of the free dropping of a coin or coins when ejected. Rails 66 of hardened material are provided on its The provided for the support of the coins, and upon which the same are adapted to slide.

The coin holding tubes are detachably connected to the body of the device. As shown in Figures 1 and 2, each of the tubes has two short strips 68 partly punched out of the back of the tube but remaining integral therewith. These strips 68 are in serted through vertical holes in lugs 72 projecting from the horizontally extending bars and are then bent back towards the tube as shown. The bars 70 are readily detachable from the body of the device, be ing provided with open slots 74: which are adapted to fit over the extending heads of belts or projections 76 secured to the body 12.

- The demountable casing is so constructed as to be readily assembled and renewed.

It is composed of a small number of parts, comprising the integral back and top, the two side plates, and a front plate provided with slots for the reception of the key levers. Each of the side plates is provided with two inwardly projecting integrallugs 78 and 80 (Figure 11) which are parallel to each otherand provide a space for the reception of the ends of the plates 60 and 62, thereby holding these plates in fixed position when the device is assembled. The side, front and back plates fit into grooves 82 provided in the base, and it is obvious thatthe entire casing can be readily assembled and held together by. only one or two bolts or screws at the top.

The operation is as follows:

A stack of coins of the correct denomination is inserted in each of the tubes 14.1 r The levers 22, 26, etc., are normally in the position shown in Figure 2, being held in place by means of the spring 30. As will be seen, the lug 54 on the end of, the bracket 52 acts to prevent the lowermost coin from sliding backward out of the tube between the plates 60 and 62. Upon initial depression of the'key 20 the lever 22 actsupon the beil'crank 26 through the roller or slide 32 and the upper portion of the bell crank moves forward into the position shown in Figure 5 with the horn 56fjust coming into engagement with the lowermost coin. the key is further depressed, the horn 56 moves along the slot 58 pushing the coin ahead of it and finally out between the plates 60 and 62. lVhen the parts reach the position shown in Figure 6, the coin will fall from between the plates on account of the cut away portion 64. The'position of the coin is shown in dotted lines in Figure 6, and as the bracket 52'is not wide, it will tumble therefrom into the chute 18.

Figure 7' shows the ejector automatically returning to normal position.

one time, and then each will deliver its re spective coin or coins into the chute simultaneously with the others, the correct change all being delivered at once.

It will be seen that herein is provided a change maker which is simple of construction and eflicient in operation, having no complicated parts to get out of order, and one which is compactly built and easy to operate. Also there is the additional advantage of having the coin holding tubes read ily detachable for purposes of cleaning or even of substitution of a full holder for an empty one in case a quick change is desired without the delay attendant to the filling of the tubes.

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

I claim as my invention:
