To all whom it may concern:

Be it known that 1, WILLIAM L. CoLEY, a citizen of the United States, and a resident of the city of East St. Louis, county of St. Clair, and State of Illinois, have invented a new and useful Improvement in Vending-Min chines, of which the following is a specification. l

My invention relates to vending machines and has for its principal objects to simplify the construction of vending machines; to reduce the size of vending machines; to deliver a plurality of the articles to be sold for each com inserted; to provide a coin chute which can be adjusted for the use of coins of different sizes; to prevent operation of the machine false coins or tokens; to provide a control pawl arranged to be tripped by a coin in the first instance and by a rotatable star- Wheel subsequently for a predetermined number of times; to provide adjustable box-supporting means the position of which is determined by the sides of the box; and other objects hereinafter described and claimed.

My invention consists in the part-s and in the arrangements and combinations of parts hereinafter described and claimed.

- In the accompanying drawings forming part of thisspecification and wherein like symbols refer to like parts wherever they occur, Figiu'e 1 is a perspective view of the machine one side of the case being removed; Fig. 2 is a longitudinal vertical sectional View; Fig. 3 is a transverse sectional view through the case and a rear view of the mechanism therein; Fig. 4 a View of the side of the mechanism inside of the case opposite the side shown in Fig. l Fig. is a fragmentary view showing the position of the initial portion of the coin chute; Figs. 6 to 9 illustrate the operation of the mechanism controlling the movement of the ejecting member.

To illustrate the invention, a cigar vending machine, in which'it is embodied, has been selected although it is to be understood that the major portion ofthe invention is applicable to machines for vending articles of any desciiption.

The outer case 1 of the machine serves only to support and protect the interior mechanism which is so or anizcd as to he use. The case is 1OVi(l('lWith'a bar2 at the lower part of the rent side to which the interior mcclumism is connected.

operator in manipulatii'lg it.

The mechanism is provided with side. frame plates 3, 4 which are provided at the lower part of their front edges with flanges 5, 6, respectively. A horizontal plate 7 is secured between said frame plates and has a front extension 3 whicli is shaped to forms. receiver. The receiver 8, late 7 and flanges 5, 6 form a groove adapts to fit over the bar 2 of the case. Screws passing through the flanges 5, 6 secure the frame to the bar 2 and thus the mechanism is securely'mounted in Said frame plates have flanges 9, 10 on their front edges extending at right angles to the planes of the plates. These flanges overlap a metallic frame 11 in which a glass plate 12 is mounted. Said plate constitutes the front Wall of a chute through which the cigars or other articles to be vended descend to the article ejecting member. It is adjustable; Near its top a shaft 13' is journaled. A knurled enlargement 14 is pro- The ends of the shaft )roject through inclinedslots 15, 16 in the rams-plates 3, 4, respectively, and carry gear- wheels 17, 18, respectively. Short racks 19, 20 are secured to said frame plates, respectively, and are arranged paralel with said slots. The lower end of the glass plate is guided by pins 21, 22 extending through inclined slots 23, 24, respectively, in said frame plates and )arallel to said slots 15, 16. The slot through which the articles to be vcnded are ejected lies between the lower edge of said glass plate/and said horizontal plate '7. the glass plate can be raised and moved forwlinlly, simultaneously, or lowered and moved rearwardly, simultaneously, as desired. Thus, the widths of the chute and the slot are simultaneously changed in like manner lo the desired dimension and thus the same machine may be used to deliver articles of widely differing sizes. To hold the plate to any given position of adjustment, 1 small dc tent is pivoted on the frame plate 4 and is. provided with teeth to engage the gearwheel 18 on the shaft 13. The dctcnt is also provided with an arm having a roughened extremity to be engaged by the finger of the Short horizontal guide flanges a are struck up from the frame plates and" have By rotation of said shaft 13.

face of the plate 7.- Other horizontal f anges 27 are struck up from the frame plates above 1 1o end. The oscillating bottom is. slotted to accommodate the connection for the link 56 and the reciprocating plate.

Small guard wings 57 are pivotally mounted on the plates 47 and rest at theirlower' These edges upon the oscillating bottom. guard w1ngsclose the space necessarily provided in the guide wings to permit the osc llation of the bottom. As the bottom oscillates and the reciprocating plate moves forward the guard wings are raised, falling imparts resume their normediately when said mal positions. l j

The upper sides of the legs of the U-shaped frame 36 are provided with teeth forming similar racks 58, 59 .which terminate'at their front ends in stops 60, 61 having curved rear faces. A shaft 62 is journaled in the ejecting member, extends through slots in the frameplates 3, 4 and carries on its endsrigidly mounted pawls 63, 64 in position to coopen ate with said racks 58, 59. Each of said pawlsis pivoted at its center and is adapted to engage the rack with either end. At its front end the pawl 63 has. a short lateral projection 65 wh1ch extends beyond the side of the rack. At its rear end it has a longer lateral projection 66. Both pawls have angular projections on their upper sides above their pivots. The angular projection 67 of the pawl 64 is engaged by a spiing 68 mounted on the ejecting memberw ch tends to prevent the turning of the pawl, but when its resistance is overcome causes the pawl to snap quickly mto 1ts new position. The angular project on 69 on the pawl 63 has its front ace curved for a purpose which will presently appear. A "star wheel 70 is pivotally mounted in position to be en aged by the lateral roject ons of the aw' 63. The starwheel has six 'teeth of w 'ch one 71 is ollset from the plane of the others so far that it cani not be engaged by the front projection 65 although it may be engaged by the rear rojection 66. A detent 72 having a shcu der 73 .is pivoted below said star-wheel and is held in contact therewith by a spring 7 -1 connected to the U shaped frame 36:, The shoulder 73 is engaged by said star-wheel and prevents right-handed rotation thereof.

. The coin chute consists of two sections. Theinitial 560131011 75 1S-1I1GllI1Cl downwardly from front to rear and lts lane is also 1nclined to the vertical. On t e lower side it is open exce t for upper and lower flanges 7,6,

77. The ower flange 76 is cut away for a short distance from the rear end of the seca'omthe. chute the tion. A substantially vertical section.78 is arranged to receive the coins as they leave the firstsection 75. It is substantially a channel and is pivoted at its rear upper corner; By means of a screw 79 mounted in a lug on the frame-plate 3 and bearing on a lug osition of the section can be adjusted. It isclamped in any desired wheel.

82 entering the frame plate 3. The vertical section 78 of the chute is so adjusted that a coin of the denomination intended to operate the machine will justrest between the pawl 63 and the front flange 83 of the section. A. magnet 84 is arranged against the frame plate 3 below the opening in the initial section of the chute formed by cutting away the lower flange 76.

-When a coin is inserted in the initial section 75 of the coin chute, it will, it the proper size, rest principally upon the flanges 76,-77. If the coin is too small it will fall out of the initial section. There is a considerable amount of friction between the llanges and the coins as they pass therealong. With the proper coin, this friction is not sullicient to prevent the coin attaining sullicient velocity to jump the gap formed by cutting away a portion of the lower llange 76. But the friction with a disk or token of softer material as lead, paste-board, or the like will be so great that the velocity of the disk or token on reaching the gap will not be sufficient to carry 1t thereover. iron or steel disks will be drawnmit ol the chute by the n'lagnet 84.

A genuine coin of the proper denomination will reach the vertical section 78 of the chute and will fall to the bottom thereof and will be 5 su 'i mrted by the pawl 63 and the front flange 83 ol the chutel This condition is illustrated in Fig. 6. drawn forwardly by means of the knob 40, the pressure of the coin will turn the pawl 63 and also the pawl 64 against the resistance of the spring 63 and bring the rear ends of the pawls into engagement with the rack. The ejecting member is now free to be drawn forward as the rear ends of the pawls will slip, over the teeth of the racks. As the pawl 63 ll", now, the ejecting member is I moves forward its rear projection 66 will engage a tooth oi the star-wheel 70.- This position is illustrated in F ig. 7. Further movement will turn the star-wheel one tooth against the resistance of the detent 72. When the star-wheelhas assumed the position illustrated in Fig. 8, however, the components of the forcesacting are'suclr'that the resistance of the detent 7 2 to further rotation of the star-wheel is greater than the resist: ance of the spring 68 to the tripping of the pawls 63, 64. As the pawl 63 is just leaving engagement with the star-wheel its front end will engage the stop 60 if by. any chance the pawls have not been tripped by the star- VVhenthe ejecting mcmber'has moved for- This position is illustrated'in Fig. 8.

ward far enough for the cigar to fall into the receiver 8 further forward movement is prevented by the engagementof the pawls with the stops 60, 61. The springs 34, 35 will now draw the ejecting member rearwardly. 'When the rejection 65 on the front end of the paw 63 reaches the starwheel it will engage the tooth and turn the wheel until the lowermost tooth strikes the shoulder 73 of the detent 72. This position is illustrated in Fig. 9. The face of the tooth engaged by the pro jection 65 is now inclined and further rearward movement of the. pawl will cause the projection 65 to slide up the inclined face and the pawls will be tripped so as to bring their rear ends into engagement with the racks.

:o The ejecting member can nowbe moved forward again and in so doing the star-wheel will be advanced one tooth, as before. On its return the pawls will be a ain tripped by thestar-wheel, as before. TT

illustrated; Upon the return from the sixth forward movement of the ejecting member the ,ofl's'et-tooth 71 will occupy the position of the tooth'to be engaged by the projection 65 2o. onthe front end of the pawl 66. ,The projection 65 is not long enough to reach. the ofiset v tooth, however, and, consequently, the pawls will not bet-ripped but Will remain with their frontends in engagemenbwith the racks.

The ejecting member cannot,'now, be pulled ,2" forward until another coin is inserted. -Ob viously, the star-wheel might have every other tooth, or every third tooth offset, in a which case, the ejecting member could be op- }io eratedtwo or three times, respectively, for each coin inserted. As the ejecting member moves forward, by means of the link '56, the

corrugated plate 55 is moved forward on the oscillating bottom 49 and the latter is oscillated. These movements agitate the cigars in the chamber in advance of the box and vertically aline the cigars over the chute with said chute so that there can be no choking.

Obviously, my machine is capable of considerable modification within the scope of my by Letters Patent is:
