My invention relates to dispensing or vending machines, pieferablyfof the coin-cons trolledV type,1for selling packaged goods-or other articles, its leading aim and purpose be# ing to provide 'a construction of thisvcliarac-f, ter which will dispense or deliver the goods with accuracy, reliability and certainty, as the applianceis operatedfroin time to time inci-V dent to the deposit of coinstherein.

Other objects and purposes of the invention Will be made apparent to those skilledin this art by means. of th'egfollowing detailed desciiption of a desirable andk preferred embodiinent thereof, which is to be read in con- 15 neet-ion with the accompanyingsheets of' drawings illustrating suoli incorporation of the invention in physical form, and through# out the several Views ofwhich like reference characters have been employedtodesignate the same structural parts..

-Bylreference tothe plurality of views of these drawings, it will'be perceived that the noveland improved dispensing or vending machine includes an upright casing or housing-2l, comprising a back wall 22, to ,which the combined top, front, bottom and end walls 23,24, 25`a'nd 26, respectively, are hinged at l 27, sok that the front part of the casing may be swung-down, giving accessto its interior forreplenishiiig purposes.`

These casing'or housing members are held in closedposition by means of a key-operated latch 28,disengageably (1o-operating with "a liXed catch29 extended forwardly from` the back wall, as shown inF ig. 5. 1

The frontwall of the housing or casing has a glass-covered window 31 (see Fig. 5) and a dispensing or discharge opening 32 through Vwhich the packages 33 orother goods, as the case-may be', are delivered tothe purchaser.

Internallyon theend walls 26, I lprovide registering, vertically-disposed.guides orrails 34,;and near the lowerpart of such housing a pair of 4appropriatelyfjournaled, front and rear, longitudinally- recessed shafts 35 and 36 areemployed in the relation illustrated. 'A lower, notched separatorplate 37 is sup,- ported by such companion or correlated shafts by reason of its front and rear marginal por.- tionsk occupying the registering recesses or cavities of thetwo shaftsfFig. 5), such low# ermost' plate 37 supporting above it an alternatinggseries or stack of 'such plates 37 and the packages kof goodsk 33-to besoldby thel machine. c scale, on line 7--7 of Fig. 6, the parts being These platesare-notched at their ends at 381torreceive and be,"V guided bythe vertical rails orbarsv 34,'and they are also cutaway at thetwopoints 39,39, vat their rontedges, and'atj4ll` at theirrear'margins, in order that rthey may escape conflict, when released by the simultaneous rockingof thetwo shafts 35 and 36, with aback, inclinedV lug 42, mounted on theinner side4 of the rear: casing wall, and with `a pairlof similarlyinclined, spaced lin; l gers 43, 43, located on the-back of the front wall. of ,the housing, thesethree supports 42 and 43 beingso located `and sloped that when v a package is deposited or dropped on them,

it will slide down by gravity out through the delivery aperture 32.

To assure that the pile or stack of packages and separator-plates shall have sufiicient Weight at all times for their proper descent, a weight 44. is placed on theuppermostpackage, and it is guided bythe 'rails' 34, ias are the plates, such Weight having an upstanding, front ange 45 ,carryinofa plate 46 designed to displayitle word 'n'ptywwhentlt comes opposite the window 31, whereby it may be read from the outside and inform the intending purchaser not torleposit aeoin, asno delivery of a package can then be effeete-el.- l -Y yj I Y From the above Vdeseri'ption, Ait will be understood that every time theafeompanion shafts-are Yrocked :simultaneously opposite directions, the -lowerm'ost 'plate land 'the .first paokage resting' thereon will-ibo released and faIL'those;aboveithernbengrtelnporarrlyiheld from deseentbyl-resfsorr ofthe .unreeessedparts of the shaftsfturningin Vunder theslowerinost supporting-plate. f' 1 The-'freed or rei-ema pmeraiisavwi-1 i0.

Thus the coinfo'rms operative mechanioal connection betweenrtlie leverand the pair of :shafts "3 5 and 36 which support `the vstack orstoclrof paclrages,=through theotrame and theother mechanical 'elements heretofore "flee :'st'n'ibed.V f Y V In' order ,that the lever when .depressed may slidethe frame downwardly .toturn these two shaitsito release a separator-,plate and rone of the packages inwth-e `manner eleH scribed, thecoinfmust `be prevented `ifi-,foin tipping over,` anclaccordingly'the lever an enlargement 73 against which-thecoin may .bear sidevvise,v 4and which )prevents the roinlfroni falling out of the frame at one side. Y y

To preclude such coin from falling out o? the -frame in ytheotlier or-'opposite direction and :to @hold-it pressed. in Iupright position aga.instthe part 73 of the lever, a' verticallyl disposed, ipil-voted, sprling pressed linger .7st, with aubeveled lowerend, is'eniployed, such `finger being hinged at 756m a shaft .roolcinglyY mounted in space-: l bearings 76, 76.

' During the Vupward stroke fof ytheTiram'e, aiter 1t-.has .been depressed to 4pachage delivery, the Afinger, Yunder the 'action vof its 7sprung,having:swung toward the lever Aas lsoonl as the Lcoin yWent down beyond the inger,th`e latteigbyreason jef. itsfsh'arp lower endybe'coines interposed between the lever and :the coin anclftips 'the -laiter over youtmot` the frame, from which it falls into the lower part ofthe casing.

To facilitate thisiactiont thefaee oi 'the lever toward the coin be somewhat beveled o'r inclined, asis @fully shown in' Fig.110.

The corresponding movement of the frame,

turned-over or hook end 79 at its top and a cam 4member 80 intermediate its length. y The frame has a projection 81 designed to zo-operate with Vsuch cam, and a lug 82 arprojecting from of lug 82 on the lateral finger arm or rod- 83,r

the operator presses' down on the handle 7l occasioned rby such swinging of the lever.

through the intervening coin, turns the two' shafts 351 and 36 andv causes Ythe discharge of one package and its delivery7 to the pur- Chaser.`

. As soon as the 'frame partakes of suoli de-A pression, its lug 81 leaves the cam element 80,

and the spring fleXes toward thelever and frame to carry its hook 79 above the lever so that the latter cannot rockfupV to its initial position until-the hook has been pressed back Y out of the way.

The descent'of the frame lowers projection. y

82 away from the finger-rod 83, and Ahence the'finger 74 is free to respond to the action of its spring, and it presses against the adjacent face of the coin and keeps the latter in place,

`When, however, the frame reaches its lowerinost position, thecoin has been carried bef low the sharp, lower end of such spring-actuated finger 7 4, and the latter rocksover further, so th at when the purchaser initiates the release o'f' `the lever, it movesup part way,

' the frame traveling likewise, and as the frame thus asceiids, vthefinger 74 wedges thepcoin out of the same, so that it Jfalls into the'bottom of the casing. i

As soon as this occurs, the spring 56 quickly elevates the frameto original position, and during this travel itslug81 engages the cani 80 and yforces the spring 77 back, carrying the hook 79 out of the path of travel of the lever, whereby the latter may ascend, under the action of its spring, to its original position.V

When the framereaches its uppermost posit-ion, the parts 82 and 83 will retract the,

finger 74 into its intial position, by reason of the coaction of the . parts 82 and 83, so that 'the next coin introduced may properly roll into place in the trame between the lever and the finger.

. unlikely, the frame cannot ascend to its'origsafety" mechanism to "prevent the operation olf-fthe appliancefii" the' e 'coin has noti been properly discharged into the casing..

It is desirable that means be provided'to prevent the Vintroduction or insertion of a coin iithesupply of packages, to be sold, in the casing has become exhausted, and accordingly the weight 44 is providedwith asprringactuated plunger 84 fitted` or supplied with a handle 85, the end .of such plunger-nor'- inally riding on the inner surface of that wall ot'- the casing adjacent to the coin-tube 64, the-upper end of which, just below itsin'outh 86,hasv registering holes,v87, 87, which are in alineinent'with another hole 88through the acent casing-wall,v this series yof holes l being in register with the position of the rod Athef'rdd84`will be automatically projected through the coin-chute, as'illustrated in Fig. 7, 'thus` preventing the introduction of" a coin vvwh-ichcould Vnot result in. the 'sale of l i one otl the packages. Y

' Then the supply otgoodsor packages' in the casing has `become exhausted and is to replenished, the accumulated supporting plates' in tlie'bottom of the casing are removedl and are inserted between. the plural.-

ity of packages 4vorarticles, so that thev .replenished stack-inthe casing `will present the 'general appearance ofl alternatingplates andvpackages, as depicted in Fig'. 5,'which,
