Application filed June 28,

My invention relates to vending machines and more particularly to that class of such machines which are adapted to be placed upon street corners, in hotels; railway stations, or other public places for mechanically vending newspapers7 magazines or other periodicals.

An object ot my invention is to provide a vending machine which will be simple and inexpen;-ive in construction, and simple and positive in its functions of vending the articles placed therein.

Alrnother object of my invention is to provide a machine ot this class with means to compensate for variation in the size ot the articles to be vended, so that perfection in operation will take place to deliver all the articles placed in the magazine ot' the inachine.

Alitother object of my invention is to notit'y a prospective purchaser when there are articles in the magazine of the machine to be tended, and to warn the purchaser whenever the nuigazine ot the vending machine has no articles remaining therein to be vended.

itnother object of my invention is to provide an improved vending machine, trom the magazine ot which, the articles can not be removed unless the proper number of the proper kind ot' coins are inserted therein, or unless an authorized person unlocks the ,'ending machine so as to enable him to replenish the exhausted supply of articles, and to remove the coins inserted therein.

Another object of my invention is to provide a vending machine which will not permit an article to be withdrawn therefrom until the coin which is inserted has finally reached a receptacle provided for the same.

Another object ot my invention is to provide a machine of the class stated which is durable in construction, inexpensive to nrnurtacture, and which is substantially theftproof.

Another object of my invention is to provide a vending machine with means to prevent such rapid return ot the mechanism to normal position which would create undue noise, eft'ect undue wear and tear upon the parts ot' the machine.

Th above and other objects of my invention will be apparent trom the following de- 1926. Serial No. 119,620.

Referring more particularly to the drawings I have provided preferably, a sheet metal rectangular container l held together in any suitable manner by rivets and screws 1.7; and having the front wall 10() of the container extending upward and cut away at 101 adjacent to the hinges 2 lor each access to the interior ot the, container when a closure 8 is in the position shown in Figs. l and 2. The said walls of the container 1 are, bent around at each side ot the opening to form flanges which extend a short distance across the space above where the hinges 2 are secured to the front wall. Hinged at. 2. to the container 1` is a closure 3 preterabl;T made of sheet metal and adapted to cover the cut away portion of the YFront 7all above the hinges7 and the top of the container. The front wall of the closure is provided with an opening 4 forming a window therein, and having preferably a pane of glass 5 .secured in the same in any suitable manner. .rhircbv the prospective purchaser i s enabled to know at a glance whether there remains any article in the vending machine to be sold.

The rear wall 71 ot the container 1 is provided with fastening means adapted to he secured to a supporting stand of any suitable type located in a convenient public place.

The container 1 is locked in an;7 suitable manner. pre terably by means of a lock bolt and keeper plate generally shown at 102,

earried by the closure whieh engages a keeper plate Secured to the rear Wall 71 ot the container.

The hinged elosure 3 ear-ries a pair ot lugs 8, adjacent the hinges 2, and eonneeted to a pair oli' arms S) provided with slots lll to limit the downward swing of the elosure 8, ou its hinges, The inner ends4 ot' the arnis l() are seeured in a manner whieh will be dersieribed more lully in another part this speeili fation. The top of the closure 3 extends beyond the rear wall T1 ot the eouA tainer and downwardly to forni a ilange 11 whieh extends over the rear wall olf the Container l to prevent rain or the like Atrom entering the rear ot the eontainer. The closure 3 is triangular shaped and composed ot' sheet metal parts which are seein-ed tol gether by rivets or in any other suitable manner.

The vending machine apable of being operated by any l!)redetermined numlgier or kinds of Coins. Coin slot G is provided in the side otl the eontainer 1 and the elosure 3 is provided with a eoin :slot 7 whieh ree' ters with the eoin slot 6 in the container 1 when the elosure 3 is n elosed position.

The carriage 46 is forced inwardly by the action of a resilient plate S9, and is adapted to slide up and down in trackways formed by flanged members 49 secured to the lower side walls of the container 1 the flanges formed being parallel to the front wall of the container. 'l'he inner surface ot' the container l forms the opposite portion of the trackway.

djustably carried over a pivot 50, adjacent to the bottom wall 51 of the container 1. is arrangeiil the articles supporting shelf 52. The shelf 52 carries depending lugs 53 provided with pins 5l which engage the forked portions of the bifurcated levers keyed to the shaft 5t). The article supportingshelf 52 is inclined downwardly towards the front end of the container and provided with depending ianges 5G and 57. The flanges 57 (Fig. S) have a series of downwardly extending slits 91 cut therein in alignment with and below the normal position of the prongs 47, to enable the prongs 7 to partially penetrate the article when the carriage 4G is depressed and to provide for the free return of the carriage and prongs in the upward travel of the same. The forward flange also forms a portion of the trackway, in connection with the flanges A-19 in alignment with them, to guide the carriage 4G in its downward travel when delivering an article. Preferably four slotted pins 58, are Asecured in the side walls of the container, the rear pairs of pins arranged above the forward pair, and all are adapted to receive the ends of the shelf 52 in the slots, to guide the shelf 52 in its horizontal shifting movement. The shelf 52 is shifted b v the action of an adjusting lever 59 (Fig. 5) keyed to the same shaft with the bifurcat'ed "levers 'l`he upper end of the adjusting le ver 59 terminates in a pointed spring finger (il). preferably riveted thereto and provided with a handle G1 which extends through the linger portion G() and terminates in a pointed lng which adapted to snap into any one of the series of arcuately arranged depressions (32 in the left hand side wall of the container. by the spring action of the pointed linger (it) of the adjusting lever 59. Secured adjacent and substantially parallel to the depression G2 is segmental bar G3 provided with Asuitable graduations 6l on its side, facing the pointed spring linger 6() of the adjusting lever 59. In this manner the shellc 52 may be tilted to the desired angle depending upon the thickness of the article to be vended, by shitting the pointer (30 along the segment (33, to render more efficient operation of the article feeding mechanism.

'lhe levers 42 are returned to normal position raising the carriage 4G to the position shown in Fig. (l of the drawing, by the action of the coil spring G5 which is secured to the inner wall of the container at its upper end, and connected to one of the levers 12 at its lower end, through a wire link (S6 fastened to one of the levers 42 substantially at the center thereof, adjacent the link Lt() and parallel thereto. To prevent the wire link GG from striking the link lo, due to the angular relation of the lever 19 to l2. when the liandle 13 is depressed, a mail coil spring G7 is provided and hooked to the coil spring G5 at 68, and secured al its lover rnd to a slet G9 in the lever 19. and disposed at such an angle to cause the wire link 66 to be pulled away from the link -tt). when the levers 19 and 42 are forced downwardly by the handle 13.

Arranged substantially parallel to the shelf 52 are pair of rods 70 extending downwardly from the rear wall 71 of the container and supported at their forward ends by the flanges 49. Slidably mounted on the rods 79 a bar 72 having its ends turned 'upwardly to form flanges thereon provided with pins 753 to engage the slots 7l in the vertical levers 75. The forward side of the bar 72 is bent downwardly to the upper portion of the trackway for the carriage 19. .Disposed on the forward side of the bar 72, secured to the flange 88, is the follower plate 7G which is adapted to push the articles to be vended in a forward direction at all times by the action of the springs 77 on the follower levers 75. The follower levers are pivoted at 78 to the side walls of the container 1 and are provided with a series of openings 79 arranged one above the other, and above the pivot 78, to receive one end of the springs in any one of the tension adjusting positions desired. The rear end of the coil springs are secured at tl() to the rear walls 71 of the container. rM-coldngly the tension of the springs 77 always exerts a pull which swings the follower lever 75 on its pivot 78 to continually force the bar 72 and its follower 7G forwardly against the rear- `most. article so that the article to be vended is next engaged by the prongs t7 in the carriage 4G.

Riveted to the upper end of the follower levers 75 are headed lugs 81 which are adapt ed to slidably retain the arms 9 by the slots 82 provided therein. in any one of the adjusted positions of the levers 9, heretofore referred to.

Disposed substantially parallel to the rods 7() and located above the same`r are a pair of similar rods 823 secured at each of their ends in the front and rear walls of the container and adapted to support a co'n collect-- ing receptacle Bt. in the forward part of the container and adjacent to the coin chute 535 which delivers the coins into the receptacle from the coin control mechanism 2?). The pairs of rods 7() and 83 also form additional reenforeement for the walls of the contaner.

Having now described the various parts of my vending machine the operation ot which will new be described Assuming the machine and the 'arious partsy to he in the position shown in Figs. 1, 2. 5 and (l. A supply ot articles are now placed in the container 1 in the following manner. 'lhe closnre l is unlocked and swung downwz'zrdly to the limit ot its pivot, liest shown in ltig. #l ot the d a\vings, and pulling the arm t) downwardly. The upper ends ot the slots S52 in the arms 9 strike the he; ded lugs S1 on the upper end of the tollower levers 75 which swings the follower lever T5 on the pivots T8. against the tension of the springs 77, sliding the bar 72 to the rear of its travel on the rod 70, carrying with it the follower levers. A series of articles i re now placed on the shelf 52 and the spring linger tl() ot the adjusting lever 5t) is moved along the segment (33 to tilt the shelt 52 a `orefletermined degree. depending upon the thickness of the articles to he vended.

The closure fl is now swung hack and locked to the container V1. lVhen an article is desired hy a purchaser he inserts the proper coin or coins through the slots (l, 7 and 99 into the coin control mechanism The handle 13 is now depressed downward agiiinst tlr` stop pin and downwardly swings with it the coin controlled level' 1t), against the tension of the spring 3l which in turn pulls the arm secured to the coin control mechanism at 22. in a downward direction ausing the actuation ot the coin control mechanism 2?) and permitting coinplcte tree actuation ot the coin controlled ltr-fr 1i). and delivering the coin through the chute R5 to the receptacle 84. After the coin contre! lever 'ttl has traveled downwardly approxinmtely the length of the slot 41 of the link 4t) the lug' llt) strikes the link forcing the same downwardly which in sequence starts the article delivering level' Ll2 in its downward movement against the tension of the spring forcing the carriage t6 downwai-dl;7 in its tracliway through the agency ot' tlse li nhy The prongs `t7. carried lnv the carriage. engaging the article to he delivered forces the same through the opening 96 in the hottom ot' the container. 'lhe article is then withdrawn through the opening 8G by the operator gripping the same, at the cntont portion 87 in the t'ront wall of the container.

'lhc return action et the handle lil and levers 19 and #l2 is automatic hy the act-ion ot the f--1prings ll and (l5. its heretotore st ated the return to normal posfition ot the machine is rendered noiseless through the action o'ti the dash pot Iii/l which dampens the return of the levers hy the piston 86 sliding into the cylinder and torcingthe air through the restricted opening 1S. The machine 1s thus' distance where they engage the lugs 8l on follower levers and wll rest` in that position, additional pressure on the closure l being necessary to swng the follower levers on their pivots again at the tension otl the springs 77.

Tilhen the articles in the container are exhausted the follower 7G takes, the position to the rar of the window and has printed thereon the words Sold out or similar words to indicate that, there remain no articles in the apparatus to he vended.
