In :the preserit Finstjance, the vending "machine :is designed to the operated-by ariiickel. Secured to plate "6 a magnet "1 .for sorting-'out-slug s-ofs'iibsta'liitialiron or ;:,steel I he seletor mechanism; also includes latchmembensfig-andr 9. The latch-finemtier fl is swing I portion 8a extending transversely of the chute section 4', said latch member being weighted to normally assume the position shown in Fig. 2 oi the drawings in the path of coins passing through said chute section. If the coin is a proper coin, it will by its weight force said latch member out of its path and pass to the track whereas if it is a slug of less weight than a nickel it will be stopped by said latch. The other latch member 9 is pivoted at l i to the plate I to swing vertically transversely of the chute section 4. It has a transversely extending finger portion 9a, said latch member being normally held by a spring 45 in the position shown in Fig. 1 of the drawings with its finger portion 9a extending across the chute section 4. The latch member 8 is provided with a forwardly extending portion at its lower end which engages the lower portion of the latch member'9 and moves the same outwardly to withdraw its finger piece 9a from across the chute section 4' when the latch member 8 is moved rearwardly out of operative position.

A blade I2 is pivoted to the inner face of the plate i at I3 for movement vertically between said plate and the hinged plate 4 to clear the selector mechanism of a slug or coin held between said plates. A coil spring hi fastened to the blade IZ at one end and at its other end to the plate 2 acts to yieldingly hold the blade in its uppermost retracted position as shown in Fig. 1, the blade engaging a suitable stop on the plate when the same is in this position. Pivotally mounted on plate 5 at [5 above the blade 12 is a lever I6 for actuating the clearer blade 43, the lever being yieldingly held by a spring 1'! in an elevated position with its free end portion engaging a stop portion on the plate 2 as shown in Fig. 2 of the drawings. The lever l'6 has a transversely extending portion 16a, to engage the upperedge of the clearer blade l2, Said lever also has a cam portion Nib to engage a roller 40 on the hinged plate 4, and a cam portion [60 to engage the upper end portion of the latch 8. When the lever I6 is depressed, the cam por tion 16b and the cam portion lBcfirst engage the roller 4a and the upper portion of the latch 8 respectively to swing the hinged plate 4 outwardly and shift the latch 23. Upon a continued movement of said lever, the portion Isa on the lever'engages the clearer blade I 2, said blade being forced downwardly and caused to sweep through the space between the plates I and 6, thereby dislodging any coin that may be held therein, the dislodged coin being ejected from the machine through a discharge chute l 8.

Referring now to a detailed description of the particular embodiment of the present invention or member between the side wall portions 59. thereof is a chute section 23, the lower end of which extends adjacent the upper end of the chute section i of the selector mechanism in register therewith. Forwardly of the chute section 23, the supporting member has integral solid portions 45 and 2d, the portion 2 5 projecting forwardly of the front wall of the vending machine casing 2 as shown in Figs. 5 and '7 of the drawings. Extending upwardly from the supporting member at opposite sides of the forward part thereof within the opening 2a are tubular guide portions 29, and 3b is a tubular guide on the rear portion of the frame i9. Supported in said guides for reciprocatory longitudinal movement is a coin receiver it, the same being in the form of a bar provided with a coin slot 27 extending vertically through the same and having a handle portion 28 at its forward end. The upper faces of the solid portions 24 and of the supporting member, as shown in Figs. 5 and '7 of the drawings, extend level with each other and with the top edges of the chute section 23, said portions 23 and "i5 constituting supporting and guiding means for a coin in the slot of the coin receiver bar 25. On the coin receiver bar 25 are laterall projecting stop portions 3! adapted to cooperate with the guide 29 to limit the outward movement of the coin receiver bar. Extending upwardly from the top of the portion 2 2 at its forward end is a lug 32, the receiver bar 26 being provided with a longitudinally extending slot 33.t0 accommodate said lug. Interposed between the lower portion of the handle portion 28 of the illustrated in the drawings, the construction shown includes an elongated supporting member or frame having spaced parallel side wall portions 19, said supporting member being securely mounted to extend longitudinally through an opening at in the front wall of the casing ,2 of the vending machine within the same a slight distance above the top of the selector mechanism. said supporting frame being fastened by bolts 29 or the like to the front wall 2 of the casing, the bolts 20 engaging apertured attaching lugs 41 on' the supporting member or frame; The side wall portions E9 of the support ing member have downwardly depending lugs 2! at thei inner ends that fit against a laterally extending plate portion 22 on the marginal portion of the plate I. On the supporting frame coin receiver 26 and the lug 32 is a coiled expension spring 34, said spring acting to yieldingly maintain the coin receiver 26 in its outward coin receiving posit-ion as shown in Fig. 1 of the drawings. From the position shown in Fig. 1, the coin receiver is adapted to be forced inwardly against the tension of the coiledspring 315 to bring its coin slot 21 into register with the chute section 23 to deliver a coin to the chute section 4' of the selector mechanism, the coiled spring 34 acting to return the coin receiver to its outer position.

Supported for rotation in suitable bearings on the elongated supporting member or frame is at the rearthereof and rearwardly of the actuator lever 16 of the selector mechanism is a transversely extending shaft 31. One end of the shaft extends beyond one side wall portion is of the supporting frame is and has fixedly mounted thereon a star or cam wheel 36 provided with a plurality of cam portions 39 equally spaced about its periphery. The star or cam wheel 38, as shown in Fig. 6 of the drawings. is

disposed in longitudinal alignment with the actuator lever 16 of the selector mechanism, the cam portions 39 on the star or cam wheel 38 being adapted to successively engage the free end portion of the actuator lever l6 and depress the same to actuate the clearer blade l2 upon abv a transverse pivot pin 43. The teeth 49a of the ratchet wheel 40 are hook shaped with curved outer faces 4021 and the pawl il'has' a hook shaped lower end portion Ma. 'A'spring 44 secured at one end to the coin receiver 25 miseries;
