Description:

-his invention relates to -improvements in Vending ,machines and .more particularly has to do pwith improved means for operating a device for clearing the selector mechanism of a slug or b~ent oristicky coins:held therein. -Goin-selector -mechanism commonly employed includes a -magnet for sorting-out slugs of substantial iron or-steel. In the use of-such-mechanism, :itoften:-happens-;that slugs are held by the magnet. Bent or sticky coins also often become 1 ldged in the -selector mechanism. Provision has heretofore been -made for clearing the selector mechanism of slugsor coins held :therein, a push rod operating clearer device-being provided for this purpose, the push rod *being ,conveniently 1 loeatedl~at the front of the vending machine for operation by the ,customer. However, due to oversight on the part of the customer or: lack of familiarity with the -mechanism, -the push 4rod is seldom operated-by the customer andconsequent- 2 ly-the selector·mechanism often:becomes clogged, requiring -frequent ýserVicing, by .a repairman, it beingnriecessary to take the coin chute apart.

T-'he primary object- of the present'invention is to .provide iniproved clearer device operating imeanslof a simple, efficient, reliable nature, which will operate the clearer device to clearnhe selector mechariism-every timea: coin is delivered thereto and -before another coin - can be inserted in the machine,aj amming of the selector mechanism being ithus -prevented.

iAnother object of the invention is to provide improved -clearer -device operating means of the character ;referred to of simple, practical construction that can be readily applied to well knoiwn -types of coin-selector mechanism.

-he -invention, wvith other objects and advantages thereof, and- the iparticular -construction, eombinations ~and arrangements of parts comprising - the -same, -will be understood from :the hereinafter 'contained detailed :descriptioh when considered in connection with the accomlpanying drawings, .foriiing part 'hereof and 'illustrating one6embodiment df the inverition.

While a preferred embodiment of the invention is illustrated in the drawings, it will :of course be understood that minor changes and modifications may be made in the particular construction shown, and the invention ,may be embodied in other forms as will appear to those skilled in the art and -falling -within the :scope, of the appended claims without departing from the spirit of the invention.

o In the drawings, the invention is shown applied to coin selector mechanism of well known construction and the, selector:mechanism will therefore be referred to only in aigeneral way. The selector mechanism is shown mounted upon -a 25 plate I suitably, secured within the upper part of the vending machine casing 2. Hingedly connected to -plate .1 is a plate 4, said rplate being normally held in a closed retracted position, as shown in Fig. - of the drawings, by :a coiled spring 30 5. The plate 4, when in closed retracted:position, is spaced. from the-plate - I and-is so formed as-to provide therewith a vertically extending -chute section, 4', and -near its lower edge at the inner side'thereof said plate is provided with- an elon35 gated track-6. Secured-to-the plate -liis a plate 6' having a lower -portion 62 spaced from the plate I a sufficient distance toprovide-a passageway for- a normal-coin so-that it-can pass laterally from -the -lower -part of -the .vertically extending 40 chute section - aalong hetrack 6. ,-This track is inclined -downwardly from its -forward end to its rear end and-serves asa-w track- to receive incoming coins-from the chute section-4' arani to -direct'the 45 same-toward-a chute - (not shown) for receiving-a coin, -which when -of -proper denomination and genuine, will at the proper rpoint -in ýIts travel through-the mechanismbe in a pbsition'to'operate :the -vending -machine. In -the present 'in50 stance, -the vending -machine is rdesigned to 'be operated-by a-nickel. Secured to plate 6' is-a magnet -7 for sorting -tot slugs of substantial iron or steel. -The -selector mechanism also includes lateh-membeis ,8. anrd 9. 'The-latch member 8 is 55 pivotally mounted at I -onýthe' plte o swing verticallyi-arael-withsaid plateand thas afnger portion 8a extending transversely of the chute section 4', said latch member being weighted to normally assume the position shown in Fig. 2 of 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 6 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 I! to the plate I to swing vertically I 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 1 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 2 section 4' when the latch member 8 is moved rearwardly out of operative position.

A blade 12 is pivoted to the inner face of the plate I at 13 for movement vertically between said plate and the hinged plate 4 to clear the 2 selector mechanism of a slug or coin held between said plates. A coil spring 14 fastened to the blade 12 at one end and at its other end to the plate I acts to yieldingly hold the blade in its uppermost retracted position as shown in 3 Fig. 1, the blade engaging a suitable stop on the plate when the same is in this position. Pivotally mounted on plate I at 15 above the blade 12 is a lever 16 for actuating the clearer blade 12, the lever being yieldingly held by a spring 17 3 in an elevated position with its free end portion engaging a stop portion on the plate I as shown in Fig. 2 of the drawings. The lever 1'6 has a transversely extending portion 6a to engage the upper edge of the clearer blade 12. Said lever 4' also has a cam portion I b to engage a roller 4a on the hinged plate 4, and a cam portion 16c to engage the upper end portion of the latch 8. When the lever 16 is depressed, the cam portion I6b and the cam portion 16c first engage the 4 roller 4a and the upper portion of the latch 8 respectively to swing the hinged plate 4 outwardly and shift the latch 8. Upon a continued movement of said lever, the portion 13a on the lever engages the clearer blade 12, 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 18.

Referring now to a detailed description of the particular embodiment of the present invention 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 2a 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 20 or the like to the front wall 2 of the casing, the bolts 20 engaging apertured attaching lugs 47 on the supporting member or -7 frame. The side wall portions 19 of the supporting member have downwardly depending uigs 21 at their inner ends that fit against a laterally extending plate portion 22 on the marginal portion of the plate I. On the supporting frame or member between the side wall portions 19 thereof is a chute section 23, the lower end of which extends adjacent the upper end of the chute section 4' of the selector mechanism in register therewith. Forwardly of the chute section 23, the supporting member has integral solid portions 46 and 24, the portion 24 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 30 is a tubular guide on the rear portion of the frame 19. Supported in said 5 guides for reciprocatory longitudinal movement is a coin receiver 26, 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 0 of the solid portions 24 and 46 of the supporting nmember, 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 24 and 46 constituting supporting and guiding 5 means for a coin in the slot of the coin receiver bar 28. On the coin receiver bar 26 are laterally projecting stop portions 31 adapted to cooperate with the guide 29 to limit the outward movement of the coin receiver bar. Extending upwardly 0 from the top of the portion 24 at its forward end is a lug 32, the receiver bar 26 being provided with a longitudinally extending slot 33 to accommodate said lug. Interposed between the lower portion of the handle portion 28 of the 5 coin receiver 28 and the lug 32 is a coiled expension spring 34, said spring acting to yieldinglv maintain the coin receiver 26 in its outward coin receiving position as shown in Fig. 1 of the drawings. From the position shown in Fig. 1, Sthe coin receiver is adapted to be forced inwardly against the tension of the coiled spring 34 to bring its coin slot 27 into register with the chute section 23 to deliver a coin to the chute section 4' of the selector mechanism, the coiled Sspring 34 acting to return the coin receiver to its outer position.

Supported for rotation in suitable bearings on the elongated supporting member or frame 19 at the rear thereof and rearwardly of the actuator lever 16 of the selector mechanism is a transversely extending shaft 37. One end of the shaft extends beyond one side wall portion f9 of the supporting frame 19 and has fixedly mounted thereon a star or cam wheel 38 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 16 and depress the same to actuate the clearer blade 12 upon a step by step rotation of the star or cam wheel s8. Fixedly mounted on the shaft 37 below the coin receiver 26 is a ratchet wheel 40. and 41 is a pawl on the coin receiver to cooperate with said ratchet wheel. One end of the pawl 41 is positioned in a slot 42 in the coin receiver 22 and pivotally connected with the coin receiver by a transverse pivot pin 43. The teeth 40a of the ratchet wheel 40 are hook shaped with curved outer faces 40b. and the nawl 41! has a hook shaped lower end portion 41a. A sring 44 secured at one end to the coin receiver 26 andt-having'its 'therýendengaging'the 'plaw 1, servesat yieldingly maintai-n the pawl in-the-Pesition shown in-Fig. Iof :the drawings against a-stop-44aýon the coi'receiverto engage a-tooth 6fi the-ratchtwhwheel. The ratchet -wheel has 6 the same-number of teeth as the ~rumber-of cam portions '"9 -on the star or cam wwheel 38 and the relative arrangement of 'th sae same is such that-when the coin receiver 26 is forced-outwardly by the spring 34 - after -an inward; stroke"of the-sanme-to deliver a. coin. to- the: chute;2, the pawl P4- will-engage one of the-teeth-4'a of 'the ratchet wNrheel";-0, -arid the ratchet'wheel will be turned one tooth, the shaft' 3 -being turned to effect ta partial revolution -of the star or cam 1,5 wheel33 sifficient-so thatýone of its-cam portions 39-Will engage and depress: the lever 1-6. to- actuate the'clearer -blade' 12. 'Upon an inward stroke of the-coin receiver 25, the outer curved face of ;the lower end '4a of the pawl- 41 will ride over the -outer-curved face-40b of the-adjacent tooth of the ratchet-wheel, the pawl-after-it is carried out of -engagement with the ratchet wheel -being swung downwardly and: forwardly back to normal position -by the spring 34. '-By the special construction and arrangement of -parts herein before set forth, clearer device operating means'of a simple, efficient nature is provided thatinsures the operation of the clearer device every time a coin is delivered to the se- o0 lector mechanism and before another coin can be insertdd in the-vending-machine so that jamming- of the mechanism is positively prevented.
