VENDING-MACHINE.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed June 1, 1914. Serial No. 842,054.

To all whom it may concern Be it known that we, MICHAEL O. Quie- LEY and LIBERTY TREES, citizens of the United States, residing at Greenfield, county of Hancock, and State of Indiana, have invented certain new and useful Improvements in Vending-Machines, of which the following is a specification.

This invention relates to vending machines, and may be more particularly associated with vending machines wherein the operating mechanism is released for operation upon the insertion of a check or coin.

The primary object of our invention is to provide a device of this character whereby upon the insertion of a coin of the correct denomination the mechanism will be released for operation for the delivery of an article, and which insures the delivery of but a single article with each operation.

A further object of our invention is to provide a device of this character which will be impossible of operation except upon the introduction of a coin of correct denomination.

A still further object of our invention is to provide a vending machine of this type further characterized by improved means for discharging the inserted mm from the vending mechanism and for automatically resetting the operating mechanism after an article has been ejected from the machine.

A still further objectof our invention is to provide a device of thischaracter which shall be simple in construction, cheap of manufacture, composed of comparatively few readily assembled parts and yet which will prove thoroughly efficient in use.

With these objects in view, together with others which will appear as the description proceeds, our invention consists in the novel combination and arrangement of parts, all

as willbe described fully hereinafter, and.

pointed out more pended claims. 7

Our invention will be more readily unparticularly in the apderstood with reference to the accompanying drawings, in Which- Figure 1 is a fragmentary. front view of a vending machine illustrating a practical em bodiment of our invention, Fig. 2 is a vertical section taken substantially upon the line 2.-2 of Fig. 1, and looking inthe direction.

Referring now more particularly to the drawings, 1 represents generally the casing of the ordinary vendingmachine, provided with a package or article receptacle 2 within which the articles to be vended are positioned, preferably piled one upon the other; a glass 3 being provided in the front of the machine adjacent the package receptacle in order that a purchaser may ascertain the character of articles contained in the machine, or to ascertain whether or not there are articles in the machine for delivery. A discharge opening 4 is provided adjacent the lower end of the article receptacle in order that the articles,'upon operation of the vending mechanism, may be delivered from the machine to the purchaser.

The improved mechanism for vending the articles stored within the casing is positioned adjacent the lower end of the article receptacle, and is mounted within a frame 5. The frame 5 supports, at its upper end, a table 6, which lies directly beneath the lower end of the article receptacle 2, and upon which the stack of articles to be vended is adapted to rest. It is to be observed that the distance between the upper face of the table 6 and the lower edges of the open end of the article receptacle 2 is slightly greater than the thickness of one of the articles to be vended, the reason for which arrangement will be more fully described hereafter. An ejector 7 is mounted for reciprocation upon the table 6, and com prises preferably a base plate 8, from the upper face 'of which extends guards 9 spaced apart a distance sufiicient to permit of the accommodation of the articles to be vended. The ejector is provided at opposite sides with depending guide arms 10, formed at their free ends with laterally extending portions adapted to engage beneath the edges of the table 6. It will be understood from this arrangement that the ejector is supported by and is free to reciprocate upon the table 6, and when in operation is adapted to slide beneath the open end of the article receptacle 2, as shown in Fig. 2. Depending from the ejector 7 is a pair of lugs 11, to which is pivoted a yoke shaped connecting link 12. To accommodate the several depending.memhersof the ejector, namely, the guide arms 10, and lugs 11, the table 6 upon wh'iclrthe ejector slide is provided with cut out portions or slots 13 and 1-1, respectively as shown in Fig. 1. From th-is arrangementit will be seen that the-L ejector. 7 is free to slide upon the table 6, and as the e ector slides forwardly from the position. shown in Fig. 3-, the-lowermost package or-article which rests upon the tablet, will be engaged by the forward edge of the base plate 8 and slid from beneath thearticle receptacle and into the discharge opening or outlet 1,v from which it may be taken by the Vendee or opera-tor. It is also to": be observed that during the ejection of the lowermost article, the article next above will drop: upon the base plate 8 of the ejector, as shown in Fig. 2, and the thickness of" the base plate: 8 issuch as to make the distance between the upper face thereof and the loweredgcs of the article-receptacle 2-less than the thickness of the package or article, and in this-manner tlieaarticle is held against movement either forward or backward, so that the deliverv of but asingle articleis insured. Upon reverse movement or retraction of the ejector, the lowermost article will drop down and rest upon the table 6', as shown in Fig; 3', to be ready to be ejected from the machine upon the next forward movement of the ejector.

As an improved means-for imparting the necessary movement to the ejector 'Z' for its above mentioned operations, a shaft 13 is employed. This shaft. is mounted in suitable supports 14: preferably below the table and: ejector, and extends at oneend beyond the side of the casing 1 to: be provided with- A pitman 16 is an operating handle 15*. I pivoted at one end adjacent the; opposite end of the; shaft 13 and is connected at its free end with the yoke shaped connecting 1 link 12 secured to: the ejector. The pitman is provided intermediate its ends with a longitudinally extending slot 17 within which extends a pin 18 from. crank arm 19 so cured upon. the said opposite end of the i shaft 13 By this construction it: is readily transmitted through the link seen that upon rotation of the shaft, the pitman 16 will be rocked from one extreme position to the other and back again, and

obviously this rocking movement will be cate the ejector 7.

12 to: recipro- .ends of which is pivoted a latch 22, extending inwardly to a position adjacent the face of the support 14. Formed, .or in any other preferred way secured upon the face of the support '14 adjacent the rotating bracket,is a lug or stop 23, which is so positioned upon thebracket as to lied-irectl'y in the path of rotation of the latch :22, whereby it will be readily seen that rotary movement ofthe shaft in one direction will be prevented; means hereinafter described being provided to prevent movement in the opposite direction. Extending fromthe opposite end of the latch isan arm 124:,upon thefree end of which issecured a coin receptacle 25; the latch being so balanced upon its pivot as to be normally in position to engage the lug or stop 28, but uponiintroduction of a coin of the correct weight to the receptacle 25 upon the free end of the arm, this balance will be overcome and the latch: tilted to such extentas to disengage from the lug or stop 23 noon the support let. The extent of tilting'movement of the latch is shown; by dotted lines inv Fig. 1. The coin receptacle 2.5 is bottomless, in order that coins of less diameter than those required may pass on through the receptacle and into the casingwithout effecting the shaft locking mechanism; The coin; receptacle is also a trifle narrower in extent than the diameter of the coin of the desired denomination, in order that upon introduction of such coin the same will be caught and held within the edges of the receptacle. It is also obvious that the coinreceptacle 25' is: in a direct communication with the discharge end of the coin chute 26' of the machine when the shaft is. in locked? position, and upon introduction of the correct coin, the latch 22 will be moved to such an extent as tobe released from engagementwith the lug 23 upon the support It, and as,

casing as the coin receptacles assumes inverted position. I

An arcuate guide 27' is secured upon' the supp ort 14: in order to. engage the end of the tilted latch 22: upon continued rotary movement of the shaft 13, to. reset the said Pii end to insure its engagement against the lug or stop 23 upon a com lete revolution of the shaft. Thus it will e seen that another coin must be inserted in the machine before thevend'ing mechanism can further operate.

In order to prevent retrograde movement of thefshaft 13, a ratchet wheel 28 is fixed to the-shaft, and a spring pressed pawl 29 is pivoted upon the opposite support 14 in engagement therewith. It is to be understood, of course, that the ratchet teeth of the wheel 28 are so disposed as to permit the pawl 29 to play over the said teeth when the shaft is being rotated in the correct direction, but the teeth and pawl will cooperate to prevent rotation of the shaft in the opposite direction. It is obvious from this arrangement that upon the introduction of the correct coin to the coin chute 26, the same will gravitate to the receptacle 25, and the balanced latch will be tilted by the weight of the coin to such extent as to release the shaft and to permit of rotation thereof, whereupon a single article will be ejected from the machine. It is obvious also that a coin of smaller diameter than that desired cannot in any way efiect the shaft locking mechanism, and it is also apparent that by limiting the size of the slot at the coin receiving end of the chute, coins of larger diameter than those desired cannot be inserted. The arrangement also presents novel and improved means for removing the coin from the receptacle, and resetting the pivoted lever to lock the shaft upon a complete rotation of the same. It will be observed that the device is of such simple construction as to insure perfect operation of the various parts at all times, with the chances of derangement or breakage of any of the parts being exceedingly small.
