Claims. (Cl. 19439) This invention relates to vending machines, and aims primarily to provide a compact, eflicient and positiveaction coin-operated vending machine for dispensing .articles of uniform size.

Another object of the invention is the provision of a vending machine which is sturdy and etficient in construction and operation and is particularly adapted for outdoor location, for dispensing cigarettes or other articles.

A further object of the invention is the provision of a magazine containing spaced vertical compartments in which the articles for sale such as, for example, packages of cigarettes, are mounted one upon the other, together with novel structure and means for selection of the desired article or brand from any one of the plurality of tiers of articles contained in the magazine.

The above bread as well as additional and more specific objects will be clarified in the following description wherein characters of reference refer to like-numbered parts in the accompanying drawings. It is to be noted that the drawings are intended solely for the purpose of illustration and that it is therefore neither intended nor desired to limit the invention to any or all of the exact details shown or described except insofar as they may be deemed essential to the invention.

Referring briefly to the drawings,

Referring in detail to the drawings, the numeral 10 indicates a substantially cylindrical housing, including the intermediate cylindrical body 11 supported on the base 12 which is provided with means for bolting it to the floor, and the cover 13. The body 11 may be rotatably supported on the base 12 with the provision of any suitable means, such as a lock joint 13a, to prevent removal of the body from the base. Any suitable key lock, such as a padlock, not shown, whose tongue may pass through an eyelet 14 on the base and an eyelet 15 on the body,"

"ice

body. A hinged door 16 may be provided at the back of the body to give access to the interior for obvious purposes.

A magazine 17 is secured within the body 11 at the front of the latter in any desired maner; for example, it may be supported on a bottom 18 whose elevation above the base 12 will be proportional to the height of the magazine. The magazine 17 comprises a cylindrical front wall 19 having a plurality of radial vertical compartments 20 provided therebehind by spaced pairs of radial walls 21 extending inward from the wall 19. Radially extending vertical end plates 22, secured to the floor 18, between which the magazine rests, prevent movement of the magazine.

A coin insert slot 23 is positioned in the cover or head 13 of the housing, from which a conduit 24 leads into a coin selector or rejector 25. As the latter is of standard construction and is available on the market as a unit, it is notillustrated in detail herein. The coin return pushrod is shown at 26, which is part of the standard coin selector. Rejected coins pass down the chute 27 into the tray 28, the latter extending through a slot 29 in the wall 19 of the magazine.

An arcuate horizontal slot 30 is provided through the upper portion of the body 11 at the front thereof, having 7 substantially the same length as the horizontal arcuate length of the magazine 17. Just below the level of the lower edge of the slot 30, an arcuate rail 31 is positioned horizontally against the inside of the body 11, and at about the level of the upper edge of the slot 30 a second similar rail 32 is positioned; both rails may be secured or otherwise made rigid with the body 11, in any desired manner. An arcuate band 33 of the same curvature as the rails 31 and 32, is rotatably and slidably mounted on the lower rail 31 and between the two rails and lies within the cylindrical surface of the two rails. Intermediate its length the band 33 has a notch 34 through which an article such as a package 35 of cigarettes contained in the magazine is adapted to be passed, as will be described below. The lower edge of the notch 34 has a lip 36 extending outward therefrom through the opening 30 and which may ride on the lower edge of the latter, and this lip is further turned downward as at 37 against the outer surface of the body 11 below the slot 36; thus the band 33 is restricted against radial movement inward or outward with respect to the body 11. A cup or receptacle 38, adapted to receive the discharged article, is formed integrally with the lip 36-37, or it may be attached thereto.

At any suitable place outside the housing, indicia may be placed above or below the slot 33 indicative of the kind or brand of article contained in the magazine column 20 corresponding to the arcuate position of the indicator; an example of this is shown by the letters A, B, and C, Fig. 1. It is apparent that by grasping the cup 38 the band 33 may be swung through the arc of the slot 30 in either direction to position the cup under the desired brand indicator.

The rails 31 and 32 need not extend around the whole circumference of the interior wall of the body 11, as is obvious, and in Figs. 2 and 3 they are shown of less than degrees, their lengths in Fig. 3 being such merely as are required for the purpose of illustration.

An approximately diametrical frame 39 is provided, having its extremities secured to the ends of the band 33. Intermediate its length, the frame 39 is provided with two spaced vertical walls 40 and 41; these walls have aligned horizontal passages 42 and 43 in which a horizontal slide 44 is slidably mounted on a diameter of the band 33. The inner end of the slide has a deformation 45 adapted to be stopped in its forward moveor swinging clockwise. the weighted end of the beam and its lowereridhas a ment by the wall 41. The entire slide is approximately Z-shaped, having the vertical upward deformation '47 and a the forward-extending horizontal portion 46. At the forward extremity of the slide, a front vertical coyering'wall 45 is rigid with the slide and has'ahand grip 49 thereon. "The diameter on whichvthe slide 44 lies is the same as V fthat at the outer end of which the cupjssispOsitioned,

and since both the slide and the, cup are fixed in relationship to the band 33, it is apparent that both swing together about the axis of the band when the grip. 49, or in fact either the grip or the cup, is moved horizontally. r e

7 The space enclosed by the wall 48, the slide portion 46, and the deformation or wall 47:,accornrn0dates one article, that is the topmost, of the articles 3 5;contained in the magazine compartments, and rnoreparticularly the topmost of that compartment 20 which is aligned with the slide 44 and" the cup .38. It is now apparent that, after thedesired alignment of the slide and thecup' with the brand of. articles in one of the compartmcntshmhas been made, in the manner described, upon movement. outward of the slide the wall 47 of the latterawill push the topmostjarticle SS through the opening Slland-jnto the cup 38. In the outermost position of the grip 49-, as do.-

In order to remove the purchased article 35 from the cup 38, the purchaser willhave to push the grip 49 and hence the slide 44 all the way' back. During this operation, when the hole 61 becomes realigned withthe end 60 of the peg 59, the peg, especiallyowing to the weighting of the forward end ofthe beam 53, will tend by grav- L V ity to fall into the hole 61. ,In doing this, the beam 53 must swing counterclockwise, 'which'it can do because "the pin 56 thereon can freely slide over the cam-like.

adjacent lower edge 67 of the barb of the hook 57, thus swinging the hook out of the way. As soon as the peg has entered the hole 61 to its limit position, previously mentioned/the hook 57 will freely swing back clockwise I andits barb will be repositioned under the pin 56. 'Thus the previous cocked position of the mechanism will have been restored by the purchaser in the act'of pushing V back the slide 30 that hemay' have access to his purchased 7 article.

walls 51 and 52, which may be provided, asshown, above and rigid with the frame wall 40, the. following parts are supported. An elongated beam or the like 53, which may be weighted as shown at 55 at its forward end, is pivotally mounted above the slide 44 on a pin 54 sup; ported in the wall 52, the pivot being'so, locatedilthat the end 55 tends to descend by gravity" Atornearthe other end the beam 53 is provided with a, rigidhorizontal pin 56, A hook 57 is freely pivotally suspended from a pin 58 supported inithe wall 51, and is sopo'sitioned normally, by gravity, its barb'will lie directlyunder the pin 56 of the beam and thus preventfthe beam from A peg 59 extendsdow'n a'r d from a betweenthese stops is. less than the width of theslide '40 bevel'6l) lying ina plane at right anglesfto thellongi.

tudinal direction of the slide 44. The latterhas an open ing 61 therethrough of smaller diameter than the diameter of *the peg' 5? so that the beveled end 6%) of t epeg 7 may penetrate only partway into the hole 61. The hole 61 is s pOSitioned-inthe slide that when thelatter is in its innermost position, shown in'Fig. 2, the beveled end of thefpeg registers partway, that is, asfully'as is poss1ble,'in the'hole 61, and the beam 53 is substantially The machine above described is particularly adaptable for location and use, out of doors, for it can readily be made completely waterproof and. the entire housing 10 7 can be made of solid and substantial construction. 7

Obviously, modifications in form or structure .m'ay- 1 be made'without departing from the the invention.

In order that the stack of articles 35 in each com partment20 may be fed upward as they are dispensed, any suitable means may be provided. One such means is shown in Fig. 5, wherein a length of rubber band having its ends 69 anchored in opposite walls 21 is tensed' by the. weight ofthe stacked articles and normally .urges' thestack upward. The tops of the walls 21 are turned inward,- as shown at 70, to provide limit stops to the upward position of the uppermost article, and the distance sothat the slide wall 47 may pass between them, Itclaim:
