To all whom it may concern:

Be it known that I, CHARLES C. SPENGLER, a citizen of the United States, residing at Rockford, in the county of l/Vinnebago and State of Illinois, have invented certain new and useful Improvements in Change-Makers, of which the following is a speciiication.

This invention relates to change-makers, and refers particularly to improvements in the basis-changing mechanism of such changemakersvthat is to say, the mechanism that adapts the machine to give change from any one of the several dierent bases within its scope. In the present embodiment these bases are one dollar, fifty cents, twenty-five cents, and ten cents.

In the accompanying drawings, Figure 1 is a longitudinal vertical sectional view on dotted line l l, Fig. 2, taken through a changemaker, showing the improved basis-changing mechanism of my invention in its application to said change-maker. Fig. 2 is a transverse vertical sectional view through said changemaker, taken on dotted line 2 2, Fig. l. Fig. 3 is a detail top plan view taken on broken dotted line 3 3, Fig. 1. Fig. 4 is a top plan view of said basis-changing mechanism. Fig. 5 is a sectionalview on dotted line 5 5, Fig'. l, taken through the change-maker, showing in side elevation the basis-changing mechanism. Fig. 6 is a view similar to the preceding one of the basis-changing keys depressed. Fig. 7 is a transverse sectional view taken on dotted line 7 7, Fig. 6. view of the change-maker, showing the operating-levers for the basis-changing mechanism.

In the drawings a change-maker of common'construction is shown, of which changemaker A refers to the framework, A to the operating-keys, A2 to the rock-shafts for supporting said keys, A5 to the arms extending downwardly from said rock-shafts, and A, A5, A5, A5, and A8 to coin-slides for dimes, dimes, nickels, quarter-dollars, and half-dollars, which coins are adapted to lie in the coinreceptacles A5, A15, A11, A12, and A15, respectively. The coin-slides are suitably mounted to have an endwisemovement in the framework and so that one end of said slides re- Fig. 8 is a detail face ciprocates beneath said coin-receptacles. A releasing-slide A11 for the basis-changing mechanism is also provided, which releasingslide has a releasing-stud A15 near one end of said slide. As in other change-makers of a similar kind, pressure exerted upon one of the operating-keys A oscillates the rock-shaft which supports said key and produces avreciprocation of one or more of the coin-slides. All of the coin-slides and their actuating-keys are restored to a normal position by means of the restoring rock-shaft A15, having pins A17 extending downwardly from said rock-shaft into suitable openings in all of the coin-slides A1, A5, A5, A7, and A5, and the releasing-slide A11, which restoring rock-shaft ispheld in a normal position by the coil-spring A15, secured at one of its ends to an arm A15 on said shaft and at its other end to a stationary point on the supporting-frame A. In the mechanism herein shown the coin-slides do not engage the coins within the receptacles A5, A15, A11, A12, and A13 unless the forward ends of said slides are raised slightly, and this raising movement is accomplished by means of the basis-changing mechanism of this invention, which mechanism and the manner of operating it will next be described.

The basis-changing mechanism is mounted principally upon an angle-bar B, fixed in any suitable manner in the framework A. On one side of the angle-bar five two-arm anglelevers B', B2, B5, Bi and B5 are pivotally mounted, the lower arm of each of which levers extends transversely beneath said anglebar. The upper arms of said angle-levers project outwardly to underlie pins B5, B7, B5, B5, and B15, slidabl y mounted in suitable openings Within the supporting-frame A and beneath the coin-slides A1, A5, A5, A7, and A5. The pawl B11, pivotally mounted upon the angle-bar B, has a laterally-extending operatingwedge B12, adapted to be engaged by the releasing-stud A15, and is held upwardly in engagement with its work by a flat spring B15.

Four basis-changing slide-bars C, D, E, and F are slidably mounted within the anglebar B upon suitable guide-studs, each of said slide-bars being provided with integral projections adapted to engage the lower trans- IOO verse arms of certain of the levers B, B2, B3, B1, and B5. The slide-bar C, being the one that controls the dollar basis, has projections C', C3, C3, C1, and C5 for all of said angle-levers, respectively. The bar I), controlling the fifty-cent basis, has projections D, D3, D3, and D1 for the angle-levers B, B2, B3, and B1, respectively. The sliding bar E for the twenty-live cent basis has projections E, E2, and E3 for the angle-levers B, B2, and B3, respectively, and the bar F for the ten-cent basis has one projection only-to wit, the projection F3 for engaging the angle-lever B3. Each of the bars C, D, E, and E has an inclined tooth C, D, E3, and F11, respectively, for engaging with the pawl B11, whereby any one of said bars is held in a rearward position against the action of its respective coilsprings C1, D1, E7, and F1. To move said bars C, D, E, and E rearwardly, four bellcranks C3, D3, E3, and E3 are provided, said bell-cranks being pivotally mounted on the angle-bar B, each having an arm to impinge against the forward end of each one of said bars, also another arm forwardly extending to underlie one of the four operating-levers C9, D", E, and F, pivotally mounted on the front face of the supporting-framework A and provided with indicating-keys C10, D10, E1, and F13.

As hereinbefore indicated, this basis-changing mechanism has four standards or bases* to wit, a one-dollar, a fifty-cent, a twentylive-cent, and a ten-cent basis. To set the mechanism for any basis of the four mentioned, one of the basis-changing keys C10, D1", E10, and F10 is depressed. For the sake of illustration let it be assumed that the dollar key C10 be depressed. The downward movement of the lever C11 oscillates the bellcrank C3 upon its pivot, moving the basischanging bar C rearward against the action of its spring C7 until its tooth C is thrown rearward of the point of the pawl B11. As soon as this occurs said pawl is thrown upward by the flat spring B13, holding said bar in its rearward position. This rearward movement of the bar C brought the projections C1, C3, C", G1, and C5 of said bar into contact with the lower arm of each of the angle-levers B', B3, B3, Bi, and B5, imparting to said levers an oscillatorymovement. Thisoscillatorymovement of the levers B1, B3, B3, B1, and B5 raises the pins B3, B1, B3, B3, and B13, which in turn raises the ends of the coin-slides A'i, A5, A, A7, and A3. The mechanism is now placed in position to give change from one dollarto wit, upon purchases wherein a dollar is given in payment for purchases of a smaller amount. The coin-slides A1, A3, A, A1, and A3, or certain ones of said slides, are moved forward by depressing' the operating-keys A of the change-maker. The releasing-slide A11 is connected to move forward by the depression of any one of the operating-keys A', and

when the releasing-stud A15 upon said releasing-slide is brought into contact with the operating-wedge B12 of the pawl B11 said pawl is rocked downward upon its pivot against the action of its spring B13, withdrawing the point of said pawl from engagement with the tooth C of the bar C. When thus released, the bar C is thrown forward into its normal position by its coil-spring C1, and this forward movement of the bar AC also restores the other parts of the basis-changing mechanism to their normal positions. When the fifty-cent key D10 is depressed, only the levers B, B2, B3, and B1 are oscillated, and consequently only the pins B, B7, B3, and Blq and the coin-slides A", A3, A11, and A7 are raised. The basis-changing mechanism is held in position upon the fiftycent basis by the pawl B11 engaging the tooth D3'. It is released by the forward movement of the releasing-slide A11 and stud A13, withdrawing said pawl from said tooth, as hereinbefore described. When the mechanism is set for a certain basis, it may be changed to another basis by simply depressing the key of the desired basis, for in passing the point of the pawl B11 the engaging tooth of the bar of the desired basis depresses said pawl suinciently to release the tooth of the bar previously held, releasing said bar to the action of its coil-spring, which latter returns it to a normal position.

It is clear that many changes in and modifications of the mechanism herein shown and described may be resorted to without departing from the spirit and scope of my invention, wherefore I desire to have it understood that I do not limit myself to the particular embodiment thereof herein set forth.
