My invention relates to article vending machines and particularly those which. are coin controlled, and its general ob]ect 1s to provide a new and improved machine of that class.

Among the specific objects of the invention one is to provide new and improved counterweight devices whereby the weight employed to elevate a stack of vendible articles is automatically lessened as the Weight of the stack decreases. A second object is to improve and simplify means for preventing a vending operation when an article or package stack is exhausted, the package support itself functioning as a stop to prevent a vending operation. A third specific object is to improve and render more certain the operation of the devices which normally prevent operation of the vending mechanism. A fourth specific object is to improve and render more certain the operation of the coin return mechanism.

To the above and other ends which will hereinafter appear, my invention consists in f the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

As illustrated in Fig. 1 the machine is enclosed in acasing 10 provided at its lower front part withdoors 11 giving access to the interior. As illustrated the machine which is of the multiple key type is provided with a plurality of finger pieces orkeys 12, five of such keys being illustrated and cach operative on an associate stack or supply of articles or packages. The common receptacle of the articles vended by the machine when any of thefinger pieces 12 is operated is illustrated at 13. At the upper part of the machine is acoin receiving slot 14 and at the right and somewhat below the slot is a. key orlinger piece 15 operative to return a coin to the intending purchaser, the receptacle for the returned coin being indicated at 16.

Thecasin 10 encloses a frame-work for supportin t e elements of the vending mechanism, sai frame-work as thoroughly shown in Figs. 8, 10 and 11 com risingupri hts 17 and horizontally disposebars 18. ertain of the uprights provide guides for article carriers, sup ports or platforms, which preferably are constituted bsheet metal members 19 of suitable form, t ese being slidable up and down along uprights orides 17. Associated with each support or p atform 19 is a counterweight element comprising a plurality of weights, two of such wei hts bein shown in the present instance and esi ate by thenumbers 2O and 21. Normall t eupper weight 21 rests on the lower an the two are adapted to slide up and down between certain of theuprights 17 The counterweight element is connected with its associate platform by flexible connection orcord 22 of wire or the like, such connection running over agrooved pulley 23 pivoted at 24. inbearin plates 25 supported on the frame-work.ord 22 runs through perforations in thecounterwei hts 20 and 21 and is provided at its end witsuitable devices 26 preventing withdrawal. It will be understood that there are twopulleys 23 and twocords 22 associated with each platform and its counterweight element, the cords bein attached to ears ortabs 19a at about the middle of the sides of the platforms, and running over their associate pulleys through their apertures in the counterwei hts, said apertures being formed near the si es of the counterweights and at midway of their depth so that the pull may be equalized. Pre erably each air ofulleys 23 are connected to turn to t er, their ivots being constituted bysha t 24, which ears near each end in one of thebearing plates 25.

The vendible articles indicated at 27 are arranged in stacks or piles on theplatforms 19 which during the oading operation are retained in their lowermost position byspring detents 28.

The machine as illustrated was especially designed for vending packages of cigarettes and thearticles 27 illustrated are cigarette packs. but it is to be understood of course that tceesmachine ma be adapted for vending any suitable ven ible units of merchandise, and that the term package as employed herein comprehends any suitable unit.

The construction is such that the pull of thecounterweight element 20, 21, 26 is transmittedthrou h cords 22 to the middle of the sides of the p atform 19 and tends constantly to raise said latform. After the platform has been loa ed with a suitable number ofpackages 27 thedetent 28 is released by hand,

thus freeing the parts so that they may be properly controlled during vending operations. Such vendin operations as hereinafter ex lained resu t in withdrawal or removal o thepackages 27 one by one from the top of the stack and the consequent upward movement step by step of the platform under the pull of the counterweight element. Obviously as the number of packages on the latform decreases the weight to be acted on y the counterweight lessens, and in order to compensate for this lessening weight and maintain as uniform an operation on the vending mechanism as possible, provision is made for automatically reducing the counterweight element. The means employed provides for each counterweight element a pair of abutments or stops in the` form ofblocks 29 suitably secured at redetermined points to certain of the uprig ts orguide bars 17. The lower weight 2O of each counterweight element is provided with cut-outs 3() which as shown in Fig. 12 register with thestops 29 so that theweight 20 may pass down freely over said stops without being affected thereby. Theupper weight 21, however, is not so cut out and its opposite corners will contact with the top of thestops 29 which will arrest theweight 21 and hold it as shown in Fig. 10 allowing the lower weight 2() to continue its downward movement alone. It will be understood that on return movement of the parts for a reloading operation the weight 2l will be picked up or lifted by theweight 20 in the course of its upward movement to the starting osition which it will occupy when the plat orms are being loaded with packages.

The vending mechanism proper whereby thepackages 27 are withdrawn one by one from the top of the stack and allowed to drop into the receptacle 13 comprises, as best shown in Figs. 8, l() and 14,:1U-shaped frame 31 horizontally disposed and adapted for sliding movement, said frame being open at the rear and its closed front side bein provided with a forwardly extending pu lrod 32 which passes through thecasing 10, and receives at its forward end outside the casing one of the finger pieces orke s 12. Suitably attached as byrivets 33 to t e underside of theframe 31 and somewhat to its rear is a.sheet metal plate 34 bent into a U-sha e viewed from the side. Secured within tlieU-shaped plate 34 at the underside of its top portion as byrivets 35 is a forwardly extendingcam bar 36 having under-cutside edge portions 37.

The series of frame members constituted each by aframe 31 and attachedplate 34 are supported side by side and guided for forward and rearward operative sliding movements by across bar 38 which is lon itudinally grooved at its upper side as in icated at 39 constituting in ellect a trough. The upper and lower parts of the.plates 34 lit ico ' The around the trough-like bar 38, the cam bars 36 being received incross grooves 40 inrearward extensions 38a therefrom.Plates 41 suitably secured to theI slide bar fit into theundercuts 37 of the cam bars and co-operatc to hold and guide the operatincr frames 31, 34 in all of their positions. ormally thefront face 34a of theplate 34 is opposite to and slightly in the rear of theuppermost package 27 on the associate stack, this uppermost package being held against upward movement by theframe element 31.

The hand-controlled vending frames are normally locked or restrained from being pulled forward to withdraw or expel the package as hereinafter explained. However, when the vending mechanism is unlocked or released and one of the frames is pulled forward theface 34 acting against the rear :face of the package will pull the package forward, withdrawing it from its stack and permitting it to fall through a guide chute 42 which leads to the receptacle 13. The entrance way or mouth to this guide chute is flared or expanded so that it underlies all of the points at which packages may be withdrawn from the five stacks. To restore theframe members 31 and 34 to normal position each is provided with a pair of draw springs 43 connected at their forward ends topins 44 on the frame 3l, the rear ends of the springs being hooked around fixed anchor pins 45. These springs tend to maintain filler blocks 34b within theplates 34 in contact with the front face of thebar 38. These filler blocks 345 are preferably of rubber or other resilient material suitably secured in place as such material lessens noise of operation. Similarly abuffer strip 45 of rubber or the like may bc suitably secured to the inner face of the front of thecasing 10 to limit the forward pull of theframe 31, 34.

As has been stated the vending mechanism proper is normally locked against operation.

locking or restraining mechanism comprises in the present instance a series or train of slide bars (Figs. 6-10) which are seated in thegroove 39 in thebar 38 and adapted for endwise sliding movements therein. In the present instance there are employed two trains of these slide bars, the upper slide bars 46 overlying and resting on thelower set 47. These slide bars are alike in construction, each comprising a neck or narrow portion joining enlarged ends, the left enlarged end of each slide bar having acam edge 48. However, the end portions of the top slides or bars 46 are slightly narrower than the end portions of the under slide bars 47 for a purpose hereinafter explained.

The trains of slide bars are adapted for contractive engagement with each other so that one may transmit movement to the others of the train within theguideway 39.spring 46a connected at its right-hand end to a in 46?) projecting upward from theriglitand slide bar 46 and at its other end to a fixed anchorage 46c tends constantly to urige the right-hand slide bar 46 towards the le t and to maintain the train of slide bars in contact, with the left-hand slide bar abutting against the closed end of the'gude bar or trough 38 (Figs. 6 and 7). Asimilar spring 47a, connected to apin 47?) projectin downward from the right-hand slide bar 4g( and having fixed anchorage 47e, performs a similar function for the lower train of slide bars 47. Normally the cam edges 48 are in the vertical planes of the forward ends or points of the cam bars 36. The slide bars do not completely lill the trough end to end when released as hereinafter explained, but there is then sufficient lost motion to permit one of the cam bars 36 to be drawn forward, entering the space afforded by thecam 48 and the slide bar registering with it and permitting thecam bar 36 during the forward pull of the vending mechanism to cam or push rightward the slide bar against whosecam edge 48 it acts, as well as all of the other slide bars of the train which lie to the right of the operated slide bar. It will be understood that the operation just described applies to both trains of slide bars 46 and 47,

these two trains operating similarly during actuation of the mechanism of which they constitute a part. Thus operated the slide bars completely fill the trough, the righthand ones abutting against a fixed stop 46m so that operation of any other of the key controlled vendingmembers 31, 34 will be prevented by the pointed end of their cam bars 36 meeting an unyielding obstruction in the slide bar train.

As stated, the upper trains of slide bars 46 are slightly narrower than the lower train; and the purpose of this is to prevent control of the slide bar trains improperly through frictional action of the pointed end of one of the cam bars 36 on said slide bar train. For example, it will be understood that once one of thevending frame members 31, 34 has been operated to cam rightward certain of the slide bars, they might be maintained in this position by pulling forward a frame member to the right of the operated frame member so as to cause the point of thecam bar 36 to press against the slide bar opposite theassociate passageway 40 and hold it frictionally against the front wall of thetrough 39. So held, repeated improper operations of the frame member first operated would be possible. However, by narrowing the upper train of slide bars such improper operation is prevented, since while the oint of thecam bar 36 might engage and fifictonally hold alower lfiar 47, theupper train 46 would always be ree.

The train of slide bars 46 and 47 are normally held against sliding movements by means comprising a coin controlled element orlever 49 illustrated in Figs. 2, 6 and 8. Thelever 49 which swin s vertically is of the first order, having a fixefulcrum or pivot 50 proecting inward from a horizonta fixedframe ar 51. The rear of thelever 49 terminates in block like portion or stop 52 which normally lies contiguous to and in the ath of the righthand members of the slide ar trains 46 and 47 and interposed between them and theframe stop 46a: (Fig. 7). The front arm of thelever 50 terminates indownward extensions 50a spaced apart and provided with lateral pins 53. These pins in turn are so spaced that they will arrest a selected coin of the proper diameter but will permit coins of lesser diameter to drop between them. The weight of the selected coin resting on thepins 53 will tip thelever 49 and raise the stop or lock 52 freeing the slide bars 46, 47 and permitting a vending operation under actuation of one of thefinger pieces 12.

As has been stated, the coin which will operate thecoin lever 49 is a selected one and to this end suitable coin selecting mechanism may be employed, that illustrated in the drawings being disclosed and claimed in my copending application Serial No. 4483500, tiled April 30, 1930, and not being comprised other than generally in the present invention. Accordingly the coin selecting mechanism need he but briefiy described. As shown in Fig. 1. the coin-receivingslot 14 affords entrance to an angular coin chute constituted by a number of angularly relatedsections 54, 55 and 56. Iron and steel coins are eliminated by a horfeshoe magnet 57 which defiects them into an out passage-way 58. Retained coins rolling down the inclined chute section 56 and subsequently falling through the lower portion thereof which is open or without bottom, first come within the influence of apermanent magnet 59 by which their trajectories are affected according to their magnetic qualities. Assuming that the machine is to be operated by silver quarter dollars, such coin designated as C will fall through achute 60 and will be arrested by thepins 53 on thecoin lever 49. Aflat spring 53a may be employed to bear lightly against the side of the selected coin to insure its proper seating onpins 53 and its retention thereon. Other coins less influenced by the ma et 59 will engage with a deflector plate`61 W iich will defiect them sidewie into achute 62 that communicates with thereturn receptacle 16. Adeflector 63 will act similarly on the coins more greatly infiuenced by themagnet 59 than silver quarter dollars.

The coin C having tipped thecoin lever 49 and freed the vending mechanism for operation as has been described, the coin is automatically ejected from its seat on thelever 49 by means operating independently thereof. The ejecting means comprises asecond lever 64 fulcrumed between its ends on a fixedpivot 65, said pivot being vertical and disposed below thehorizontal ivot 50 of the ever 49. Inconsequence t e lever 64 is adapted to swing in. a different direction from thelever 49 and at substantially ri ht angles thereto. As will be clearly un erstood from Figs. 6 to 8 the forward arm of thelever 64 terminates in an inwardly oil'-set contact portion 64a whose plane is slightly to the right of the plane of the o erating coin C as it rests on thelever 49. he tipping of said lever by the coin brin s the lower portion of the coin oppositet e contact face 64a so that when thelever 64 is actuated thearm 64 moving to the ri ht will cause thecontact face 64a to eject 51e coin laterally from thepins 53. When thus ejected the coin will of its own weight drop straight downward through the lower left hand portion of thechute 62 which is open at 62a and will enter the Haringopen mouth 66 of acoin chute 67 communicating with a receptacle contained within the machine casing. The swinging of thelever 64 as described is effected by ablock 68 which is secured to and projects downward from the right-hand end portion of the right-hand slide bar 47. This block, when the trains of slide bars 46 and 47 are moved rightward during the vending operation, will contact at its right-hand face with the rear arm of thelever 64 and will swing the lever about thepivot 65 as described. The parts are timed so that the coin ejecting function of thelever 64 will take place at the proper time in relation to the releasing of the operating trains.

In order that the mechanism shall operate with certainty and ease, it is essential that thecoin receiving lever 49 shall be freely mounted, that is, the lever should be normally free to swing on its pivot so that it may be properly responsive to the weight of the selected coin to release the vending mechanism. It is also essential that thelever 49 be restored quickly and certainly to its locking position after a package has been vended. To this end I have provided a restoring means for the lever which is normally ineffective but is brought into operation towards the end of the return stroke of a vending key or ngerpiece 12. This restoring means 1s operative independently of and apart from thelever 49 itself. As shown in Figs. 2, 6, 8, 10, 14 it comprises alever 69 arranged at the right-hand side of the machine and to the rear of thelever 49, saidlever 69 having a fixedpivot 7 0 between its ends. The forward arm of thelever 69 terminates in inturnedparallel lips 71 perforated to receive a vertically disposedspring pin 72 having a reduced shank portion which receives acompression spring 7 3 confined between theupper lip 71 and the bod)T portion of the pin. Outside theupper lip 71 the shank portion is threaded and receivesadnuts 74 forA limitin downward movement of the pin. Norma y the lower end of thepin 72 is disposed above and spaced from thestop block portion 52 of thelever 49. The rear arm of thelever 69 terminatcs in n block-like portion orweight 75 which ovcrlice a square pin-7 6 arranged to slide vertically in astationary bearing block 77, the lower end of thepin 76 carrying a pivotedroller 78. Theroller 78 is disposed for actuation by acam 7 9 which 1s mounted on and projects upward from the righthand end portion of aslide bar 80 which is. arranged for end-wise sliding movements in astationary trough 81 of bar-like construction which extends transversely of the machine near its rear, being behind and somewhat below thebar 38.

Viewed from the rear as in Fig. 14 the right-hand end ortion of thetrough 81 1s provided witha c osure 82 which limits movement of theslide bar 80, and normally sai slide bar is maintained in contact with said closure by a spring183 anchored at one end to a fixedpin 84 and aving its olpposite end engaging a pin 85 carried byt e slide bar 80 and projecting downward therefrom through aslot 86 in thetrough 81.

It will be apparent that movement of theslide bar 80 towards the right-hand side of the machine will cause itscam 79 acting on theroller 78 to lift the end of which acting on thelock 75 willswmg thelever 69 downward causing thespring pin 7 2 to co-operate with thecom lever 49 to restore it to normal position. This cooperation is preferably effected by a sudden action in the nature of a snap action which will occur during the latter portion of the return stroke of avending frame 31, 34. To obtain thisresultthe slide bar 80 has mounted on its upper face a set ofspringfingers 87, one in a ignment with each of t e vendin frames (Figs. 8, 10, 14, 15). The spring ngers 87 are angular in shape comprising an upright portion and a horizontal ortion havin a justable 4stop face 87a. Each finger 1s provided wit apivot pin 88. Pairs ofears 89 pro'ect upward le cam bar from and integral with theslida 80, each pair eing spaced apart to receive theassociate finger 87 and provide bearings for its pivot pin. Thepivot pin 88 projects outside one of theears 89 and receives acoiled spring 90 arranged to maintain the finger normally in upright position as shown 1n Figs. 10, 15 and 17.

Just to the rear of eachfinger 87 at its upper portion is a horizontally disposedcam plate 91 having a working edge orface 92, said plate being secured as by pins orrivets 93 to the under side of the rear portion of the upper part oftheplate 34 of the associate vending frame. l y

The construction is such that when one of the vending frames is pulled forward by its d been described.

in 76, the upper.

cam plate 91 will depress will turn on its pivot due to the yield of its sring 90 so that the forward movement of t e vendin framewill not be interfered with andthe n er will ride over the under face of the cam ate 91 without affecting theslide bar 80 ig. 16). As soon as theplate 91 clears the' finger the latter will snap back to normal position under influence of its spring.

0n the return stroke of the vending element, however, as it a movement thecam e ge 92 will engage w1 thefinger 87 as illustrated in Fig. 18 and the finger now being unyielding by reason of the contact of its stop face 87 a with the barSO will force said bar rightward, causing thecam 79 through the connecting train of devices to swing thelever 69 on its ivot thus bringing thespring pin 72 into e ect to restore thelever 49 to normal position as has As soon as t ecam ede 92 clears thefinger 87 thecam bar 80 w l be restored to normal position by its spring, thus releasing thelever 69 which will return to normal position shown in Fi 2 by reason of itsrear arm weight 75 overba ancing its forward arm.

Comparing Figs. 2, 3 and 4 it will be observed that normally and prior to the action Jof the coin C, the spring pm is spaced above thelever portion 52 as shown in Fig. 2. When the coin acts, its weight will turn thelever 49 and bring itsportion 52 in close proximity to the end of thepin 72, as illustrated in Fig. 3, so that the spring device constituted by thepin 72 and itsspring 73 will be positioned to act promptly when theslide bar 80 with itscam 79 begins its operation, which, it will be borne in mind is after the coin has been ejected from thelever 49. The restored position of thelever 49 is i1-` lustrated in Flg. 5 which shows thelever 69 still actin on saidlever 49 just prior to releasing. e construction is such that a rapid and effective return movement of thelever 49 is insured by means which is operated independently of it and which normally is ineffective and disconnected from saidlever 49, thus leaving it free to function with certainty and accuracy.

It sometimes happens that after a. coin has been inserted the vending mechanism cannot be operated to vend or withdraw an article, as, for example, where the o erated key 12 the associate thefinger 87 which proaches the end ofkey 12 is associated with an exhauste stack.

of course, the coin inserted by In such cases,

should be returned to the intending purchaser him and means are provided for this purpose -ing 62a registerin portion is a cam plate 941; which normally lies behind and in the vertical plane of the sto -block portion 52 of thelever 49.

draw-spring 96 connected to therod 94 and to the stationary pin 97 on thebearin cam 95 rearward. Adash ot 98 of ordinary construction is supporte on the bearingmember 95 and has itspiston rod 99 attache to therod 94.

In operation, assuming that thelever 49 has been tipped to the position shown in Fig. 3 by a coin which the intending purchaser desires to be returned, he pulls the finger piece outward, thus drawing therod 94 forward and causing thecam 946 to move horizontally forward and act against the lower rear corner of theblock 52 of thelever 49. This camming action has the effect of still further tipping or turning the lever on its pivot to the position shown in Fig. 4. As thelever 49 swings downward from the Fig. 3 to the Fig. 4 position the under edge of coin C will be brought into contact with apin 100 which rojects laterally from thechute 62. As ownward movement ofthe lever continues, the eii'ect of thepin 100 will be to hold back the coin which will thereby be rolled off of thepins 53 as illustrated in Fig. 4 and will pass down the extension of thechute 62 into thereturn receptacle 16.

The dash-pot will operate to slow up the return movement of the coin return elements when released and is employed preferabl as an extra precaution in association wit a gate device which prevents the coin from passing downward into themouth 66 of thechute 67. Normally thegate 101 occupies a depending position, hanging straight down from its pivot 101.11 on the rear lower portion of thechute 62 and leaving open the left handlower end 62a of said chute, the openwith themouth 66. Thegate 101 is adapte to be actuated by a spring 1g2carried by aprojection 103 on the rod 9 As said rod is pulled forward the free end of thespring 102 acting against thegate 101 will swing it upward and forward, closing theopening 62a. Owing to the yield of the spring the forward movement of therod 94 may continue to effect release of the coin after the gate has been closed. The gate of course will drop to open position through gravity on the return of the parts to normal position.

Various changes may be made without departing from the spirit and scope of the invention.
