-1 Claim. (Cl. 31269) This invention and more particularly to a coin controlled dissimple and inexpensive construction and positive in its function of vending the articles contained Another objectof mechanism which will receive a mechanism of the machine.

A further object of the invention is to provide a closure member for the coin insert slot which machine so with the front coverremoved;

Fig. 2 is a perspective view of the machine;

Fig. 3 is a side nism in the machine, the housing and operating shaft bein shown in section;

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1 and.

Fig. 5 is an enlarged line 5-5 of Fig. 1.

Referring to thedrawings, the housing I 0 comprises a back plate I? havingvertical side walls l4 and a removable front wall .16. The backwall sectional view taken .on

nel which receives the articles of merchandise in stacked formation.

An inverted U-shaped bracket 2t! is secured to the back wall l2 through lateral flanges '22 on the legs 24 of the U-shaped bracket 20. The base of the U-shaped bracket 2!] forms afioor or support for the articles to be dispensed.

The legs 24 of the bracket 'Zllare provided with aligned opemngsfor rotatably supportinga transformed on the piston stem annular opening for the reception of a coin. The arm 32 being carried by the sleeve 28 is independently movable relativeto the arm Mlwhich is fixed to the shaft 26, except when a coin is positioned in the opening formed by the semi-circular edges 33 and 44.

The shaft 26 extends through the housing at one side thereof and is provided with a handle 6 for turning the shaft 25. By rotating the stationary so that the delivery arm 34 is not moved.

A coin slot 48 is provided in the front wall and chute 513 by a bracket 52 secured the back plate [2. This chute directs the coins,

E2 is 55) and a spring 64, surrounding the stem, is under compression between the flanges 5t and 62. The outer end of the piston stemlifl rides on a cam track 66 formed in a bracket 68 secured to the back plate [21.

adapted to pass therethrough. A flange When a coin is in the coin the two flanges 36 and G2 and rests on the piston head 53, the coin forms a key the floor of the bracket 20'. As the piston stem 50 moves forwardly and upwardly along thetrack, the piston head 58 pushes the coin upwardly out of the coin opening and it is discharged to the coin receptacle l2 freeing the connection between the arms 32 and 50.

A pin it secured to the shaft 26 passes through a slot it in the sleeve 28 and has a tension spring it between the pin it and the back plate 12 urging the shaft 26 in a clockwise direction. While the pin 74 has lost play movement in the slot 16 it does engage the ends of the slot to cause rotation of the sleeve 28 with the shaft 26 and limits its free movement. Thus the spring 78 returns the shaft 25 and sleeve 28 to their normal positions and after a predetermined turning of the shaft 25, the pin Hi turns the sleeve 28.

The coin opening in the flanges 36 and 42 is of a diameter no larger than the diameter of the coin to be used in the machine so that larger coins will not rest on the piston head 53 and serve as a key for interlocking the arms 32 and 40. An opening 85, having a diameter less than the diameter of the required coin diameter is provided in the bottom wall of the chute 55 so that coins, smaller in diameter than those required to accurately fit the coin opening between the flanges 3e and 42, will drop through the opening 80 and pass through a coin return chute 3?. into a coin receptacle 84, arranged on the front cover, at the operators disposal.

A permanent magnet 85 is arranged in the coin chute as to intercept and retain coins not of the proper metallic content.

A plate 68, floating on the top of the upper article in the machine, carries a hinged plate as at its forward edge. The plate 2i] extends rearwardly and has a projection 92 extending lateral- 1y beyond the edge of the stacked articles. The

forward edge of one of the angle plates is is a formed tapered at M, as shown in Fig. 3, and the extension s2 is guided, by the tapered surface, to a vertical position as the stack of articles is diminished. When the last articles have been removed from the machine the extension 92 covers the coin insert slot at, thereby preventing the operator from inserting a coin in an empty machine. The extension 92 can not be pushed rearwardly due to the fact that it is backed up by the tapered edge 94.

The front wall it is removable and is held in closed position by a key lock 96 of conventional design. The article discharge opening is shown at 98 and is normally closed at the rear by a swinging plate iflil. When the articles are dis charged, the plate I is free to swing forwardly and upwardly, permitting the article to be pushed through by forward movement of the arm 34. The plate Hit is prevented from swinging rearwardly and upwardly by its contact with the articles in the machine. This arrangement prevents the operator from reaching through the discharge opening to remove the bottom article.

The discharge opening 82 is formed in a casing tea which has a window Hi l for containing and displaying one of the articles which corresponds to the articles in the machine. The panel 105 may be decorative, such as a mirror, or display advertising material.

The machine is filled by removing the front wall It and placing the articles in stacked form on the floor 20 in front of the arm 34. The plate 88 is then placed on the upper article of the stack with the extension resting against the tapered edge 94.

arm 32 forwardly rotating the sleeve 28.

The

arms 32 and 30 draw the discharge rod 34 forwardly moving the bottom article through the discharge opening 98.

When the operator releases the torque on the shaft 26, the spring 18 returns the shaft to its normal position and the pin, acting against the end of the slot 16, returns the sleeve to its normal position with the discharge rod 35 positioned behind the next article.

claim.

We claim:

A vending machine comprising a housing having an article supporting floor, a pair of vertically extending angle members forming a channel above said floor for positioning the articles one above another on the floor, coin controlled mechanism operable in conjunction with manually controlled means for dispensing the bottom article through an opening in said housing, a coin receiving slot in said housing, the forward edge of one of said vertically extending angle members eing tapered forwardly and downwardly, a floating plate resting on the top article in the channel, and a plate hinged to the forward edge of said floating plate and having its rear edge resting on the tapered edge of said angle member,

said hinged plate slidably mounted along the tapered surface of said angle members when said floating pla te is moved downwardly whereby it is hinged forwardly during downward travel along the tapered surface and covers said coin receiving slot when said floating plate reaches said STANLEY JAMES HORSCH.
