(Cl. 1911-69) Fig. 13 is a detail perspective View of the plung This invention relates to vending machines operable in response to insertion of a coin of certain dimensions. Objects of the invention are to provide a de v5 vice of the class described which (a) is adapted to contain a supply of and deliver for a single coin and by a single operation a plurality of arti cles of different shapes and sizes but which are designed for conjoint use such as a paper cup and a predetermined number of medicinal tablets to be taken with water in such cup; (b) shall be compact, convenient, simple, economical and ef ficient in construction and operation; (c) shall be eñìciently safe-guarded against “milking”, i. e. unauthorized extraction of contents; (d) shall at all times show at a glance the number of tablets remaining in the container and (e) shall protect the contained tablets from damage or atmospheric deterioration. 20 With these and other objects in view, `all of which will more fully hereinafter appear, my invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed and as r25 illustrated in the accompanying drawings in which like characters of reference -indicate cor responding parts throughout and in which Fig. l is a front elevation of my vending ma chine.

Fig. 10 is a fragment illustrating position of certain parts when dropping a >tablet at comple tion of inward stroke of the plunger. Fig. 11 is a fragment illustrating position of er element complete. The Figures 10, 11 and 12 areon a relatively enlarged scale. My invention is designed for ythe vending of a 5 paper cup and two medicinal tablets- and will be described interms of such construction and use though, obviously, the number of Y tablet containing and dispensing units may be increased or diminished as desired in order to vend, with l0 a single cup, the number of tablets desired for a standard dose. n My invention comprises a back 20, to be at tached to a wall or other support in any suitable manner, not shown, to which back I attach a 15 housing 2| preferably by hinges 22 and lock 23. ’ The principal part of the mechanism is mounted in and carried by the housing 2l, a few parts beingcarried on the back 20 and thereon posi tioned to cooperate with certain parts carried 20 in the housing when vthe-device is closed. Exteriorly, the housing is provided with a cup rem'oving opening 24, a tablet removing opening 25, windows 26, a coin-chute housing 21 having a coin slot 28 therein,and a plunger bar 29 having 25 push button 30. Interiorly of the housing and above the open ing 25 I provide shelf 3| suitably supported on the walls of the housing and covering a coin box 33 having receiving chute 33a and slidably sup- 30 ported by flanges 33h on brackets 32. Gaskets 34, of rubber or other suitable material, for seat ing and sealing the lower ends of the tablet tubes, later described, are carried by shelf 3| which shelf is also provided with holes 35 and 36 aligned 35 between the gaskets and for the purposes here inafter described. Tubes 3l, preferably of glass, normally have their open lower ends seated upon gaskets 34, the tops of the tubes being covered by caps 38, 40 the capped upper ends of the tubes having a loose sliding fit within cylindrical guides 39 depending from the top of housing 2l. Resilient means, as springsliû within the guides 39, are provided for normally holding the lower ends of the tubes 45 tightly against gaskets 34. ' Bar 4l performs several functions, including holding the tubes in fixed interrelation, providng means by which the tubes may be lifted and co operating with fixed guides hereinafter described, 50 for holding the tubes in proper alignment during reciprocation. This arrangement is conveniently Fig. 12 is a fragment illustrating the catch in ~ accomplished by forming the bar 4l in two parts as-clearly shown at Figs. 4, 8, 10, 11 and 12, and _position to prevent unauthorized inward move coin and -certain parts during the inward stroke of the plunger. 56 ment of the plunger. providing ridges 42,\which may be> molded `with tillY 2 . 2,133,525 1 the tubes, between which the bar 4| engages the tubes 31. The two parts of the bar 4| Vare clamped together, with the tubes thus clamped between them, by suitable means, such as cleats 43 fastened to bar 4|, by any suitable means, not shown. The bar 4| is provided with a suitable runway in which it vertically reciprocates when the tubes are raised and lowered, such runway being conveniently formed by members 44, pro jecting from the back 20, the end wall of the housing 2|, guide 45 and cleats 46 and 41 at tached, respectively, to the end wall of the hous a hook 1| adapted to engage in hole 35 under certain conditions and resilient member 12 is pro vided for forcing hook 1| into hole 35 whenever hook 1| is over hole 35 and there is no coin of the required size in slot 65. Spring 13 is attached, by any suitable means indicated at 14, to the front wall of housing 2| and to spring post 6| whereby to retract the plunger assembly to and resiliently hold it in for ward, inoperative, position. ' The tubes being supplied with tablets 48 sur 10 mounted by the plug 49 as illustrated at Fig. 9' ing and to guide 45. ' ' and a nest of cups being placed on plate 51 as ' The tubes 31 are adapted to be loaded with illustrated in Figs. 3 and 6 and the device being tablets, indicated at 48, above which, freely slid able within each tube, is a plug 49,ì having a coni~cal base 50, for the purpose hereinafter described and having characters upon the sides of the plug visible through windows 26 when the tablets with 20 in the tubes have been reduced to or below the level of the windows, all as clearly illustrated at Fig. 9. . A bent coin-chute 5| is provided within the housing 21 leading from the coin slot 28 to the 25 hereinafter described point'at which the coin is received for operative purposes. ' closed and the plunger assembly in forward, in 16 operative, position all as illustrated in Fig. 4, the operation is as follows: A coin of the dimensions for which the machine is constructed, preferably a nickel, is inserted in slot 28 and drops through chute 5| into slot 65 20 coming therein to rest on member 61 all as illus trated at Fig. 8. Pressure is then exerted on but ton 30 forcing the coin against bar 4 I. It will be noted that the parts areV so proportioned that the coin will contact the lower front edge of bar 4| I provide a compartment for an inverted nest of Cups as illustrated in Figs.,3 to ’1 inclusive. The at a point on the edge of the coin above its hori- ` zontal diameter as it thus rests upon member 61 so that the pressure on the button 30 will cause the coin to act as a cam and lift bar 4| and, opposed guide 52 is positioned oppositely on the the tubes and the pressure of springs 40. The bar Also within housingV 2| and above opening 24, 30 guide 45 forms one ,wall of this chamber and an side wall of housing 2|. The front wall of housing 2| forms a third guide 53 while a fourth guide'54 is carried bythe back 20. Guides 45 and 52 are 35 opposite and spaced apart slightly in excess of the diameter of the periphery of the rims of the cups and the guides V53 and 54 are similarly spaced when the device is closed so that in closed posi-` tion of the device the four guides form a run 40 way in which the inverted nest of cups may move freely up and down. Normally the nest of cups rests on a portion of the plunger assembly as illustrated at Figs. 3 and 4 and as hereinafter more fully described. 45 Slide 55 is provided beneath the tablet dis therewith the tubes 31, overcoming the weight of 4|, with the tubes, will be lifted to the height of the top of the coin and the parts are so pro portioned that the vertical distance to the top of the coin from the point on the coin where it ñrst 85 contacts bar 4|, is slightly greater than the thick~ ness of one of the tablets in the tubes so that when Vbar 4| is raised sufficiently to permit the coin to pass thereunder, the bottoms of the tubes will have been raised above the gaskets 34 a dis 40 tance sufficient to expose one tablet under each tube and permit the same to be slid from under the tube. 'I'he pressure being continued, the coin slides beneath and supports bar 4| with the attached tubes and'wings 56 contact the exposed 45 charge mechanism to slide the dropped tablets. ~tablets and push them from under the tubes and coincidently support the remaining tablets within easilyY reached manually through _said opening. the'tubes.

Y Coincidently, when the plunger assembly 55 reaches the end of its inward stroke- the inertia of the coin will cause it to roll down along the inclined Vend 61a of member 61 and into coin re ceiving chute 33a and thence into coin box 33. Should the inertia fail to thus drop the coin, 60 it will be shoved off into the chute 33a by bar14| when it contacts said bar on the return stroke of Plunger bar 29 is notched as at 64 and bifur cated to form a coin receiving slot 65 and the the plunger assembly responsive to the pull of spring 13.V Coincident with the above described tablet 65 dropping operation, the plate 51 is ~moved out Such downward extension and recess being pro vided for> the accommodation of member 61 which performs the combined function of a coin stop from under the nest of cups but during this move mentgwedges 60 enter the space between the rims 65 bifurcation continues to the bottom of the bar 29 and backwardly therefrom forming recess 66, and ksafety catch. Member 61 is pivoted between or beads of the two lowest cups thus separating the bottom cup from the balance of the pile by 70 the bifurcations as at 68 and is notched as at 69, lifting said next-to-the-bottom cup and those a stop 10 being mounted between said bifurca thereabove, leavingl the bottom cup resting on tions and within said notch 69 to limit the down- » shelf 51 until the plunger assembly reaches the ward movement of the inner end of the member 75 61.
