although it is not necessarily limited thereto.

In the past, numerous efiorts have been made to provide a vending machine whichis suitable for vending articles of irregular shape. In the vending of articles of this type, such articles usually cause clogging of the machine. For instance, one of the articles might become caught between the topplate of thevending machine and the vender lever plate, thereby rendering the machine inoperative. In order to operate the machine when this occurs, it would be necessary to pull onthe vender lever with-suificient force to break the article, or if the article is extremely hard, it would be necessary to take the machine apart and to remove such article from the position where it causes clogging of the machine. There have been several types of machines devised for overcoming these undesirabilities but none of theseprior art machines are entirely satisfactory. These prior art machines are complicated in structure and are expensive to manufacture. Then, too, prior art machines of. this type are usually of such a structure that they readily become out of order and require considerable maintenance. Furthermore, they are not entirely effective to accomplish the purpose for which. they were intended.

\ One of the objects of my invention is to provide a'vending machine of thetype indicated which is extremely simple and inexpensive t manufacture.

Another object of my invention is toprovide a vending machine which is capable of vending articles of irregular shape without danger of such articles becomingclogged in the operating mechanism of such machine.

Another object of my invention is to provide a vending machine of the type indicated which is effective to vend articles of irregular shape without clogging of the machine, and which will vend articles of irregular shape and which are easily broken, without breaking such articles.

Another object. of my invention is to provide a vending machine of the. type indicated which is extremely rugged in structure and which will not readily become out of order, thereby requiring lit- 22 Claims. (Cl. 221--108) l fingers have their outer ends disposed above the opening in the top plate, which normally lies above the measuringpocket of the vender lever plate, and are provided with portions which normally project into said opening and terminate substantially at the lower surfaceof the top plate. The fingers are of such a shape and are so disposed that when the vender lever plate is actuated to move the measuring pocket, which will be filled with the articles, over. the discharge chute and underneath the top plate proper, the outer ends thereof will move upwardly, if any of the articles project above the upper end of the pocket, and will therefore prevent clogging of such projecting articles between the vender lever plate and the top plate. The fingers are so shaped that'they will not tendto bind with each other. Means is also provided for limiting the upward movement of the fingers. Furthermore, means is provided so that even though the fingers are moved upwardly, when the parts of the machine are in inoperative position, the articles cannot be discharged through the discharge chute.

The preferred embodiment of my invention is sh-ownin the accompanying drawings wherein similar characters of reference designate corresponding parts and wherein: e

In the accompanying. drawings, I have shown portions of a vending machine to which my invention is applied. I have shown merely those parts of the machine which are necessary for .a clear understanding of. my invention.

, the to'p plate 11- adjacent the outer periphery the plate 19.

ing 4 which is disposed directly above a discharge chute (not shown). When the parts of the vending machine are moved to vending position the articles are adapted to passl'through the open-.

ing 4 and then to be discharged through the discharge chute as will be hereinafter understood.

The plate 3 is also provided with a raised flat portion 5. This portion 5 of the plate is'adapted to normally constitute the bottom of a-measuring pocket 6 which is formed in a vender lever plate 7. The vender lever plate 7 is mounted within the bowl casting 1. This vender lever plate preferably comprises the main body portion 8 having the measuring pocket 6 of segmental form, formed therein. The capacity of this pocket may be adjusted by suitable means, (not shown), if desired- This vender lever plate also comprises a handle 9 which projects through and operates in a slot 10 formed in the wall of the 30* casting 1. The vender lever plate is rotatably mounted in the bowl casting 1 and rotation of such plate is controlled by suitable coin-controlled mechanism-(not shown). I

7 Atop plate 11 is suitably mounted on the upper end of the bowl casting 1. This top plate is circular-in form and is provided with a radial extension-12 having aslot 13 formed therein, (Figure 5), which is adapted to communicate with the ,upper end of the coin channel. The top plate 11 is also provided with a circular groove 14 which is adapted to receive the lower end of a glass bowl 15 Which'is adapted to contain thearticles to ,be vended from the machine. An aperture" 16 of segmental form is also formed in the top plate 11 and this aperture normally overlies the measuring pocket 6 the vender lever plate 7.

A flange 17 is formed on the upper surface of thereof. This fl ange 17 extends from a' point adjacent one edge of the aperture 16 a substantial distance around the top plate 11. A second flange 18 is also formed on the top plate 11 adjacent the center thereof and'this flange 'also' extends from a point adjacent oneedge of the aperture 16 too. point opposite the'point where the flange 17 terminates. The flanges 17; and 18 are curved in the same are. About midwaybetween the height of these'two flanges, a plate 19 is disposed. This plate as well as the flanges 1'7 and 18 may be cast integrally with; the base plate 11. The flanges 17 and 18 and the plate 19 are so disposed that a chamber 20 is formed beneath The plate 191s provided with a series of apertures 21 (Figure 6) and any salt or other waste material from. the articles that falls on such plate will pass" through these apertures. r g

The rear end of the flange 18 isprovided with an opening 18' and the rear end of the flange 17 is provided with an opening 1'7; These openings are adapted to receive the, ends of a pin 21 which also passes through openings formed in the rear ends of a plurality of fingers 22 These fingers are mounted betweenthe fianges'l'l and18 above which is formed in lower surfaces spaced above the plate 19 so that they may be swung upwardly about the pin .21 as a pivot. The rear ends of the body portions of thefingers 22 are also preferably spaced apart so that there will be no tendency for the fingers to bind at this point. The forward ends of the body portions 23 of the fingers are normally adapted to rest upon the upper surface of the plate 19. (Figure 2).

The body portion of each of the fingers is provided at'its forward end with a downwardly projecting portion 24. These portions 24 extend downwardly past the outerend'of plate 19am terminate at apointfsubstantially in alignment with the lower surface of top plate 11. It will be apparent from the drawings that these portions 24 project; through the aperture 16 in the top plate 11. The extreme outer edges of the portions 24' are preferably curved, as'at' 25, to form a cam-like surface thereon sothat the fingers will readily ride up over the articles.

It will be obvious thatwhen the outer ends of the fingers 22 are swung upwardly they will swing in a vertical arc. This'is due tothe fact that the body portions of the fingers 22 are are uate in shape and the fingers swing about a fixed pivot 'point,-namely, the pin"21; Therefore, it is desirable to provide means for preventing binding of the outer ends of the fingers 22 when they 'are'swung upwardly. Each side of the forward portionof the fingers 22 is therefore curved as at 26 and 27. The are of curvature of each side of each finger is the same as the vertical are through which the outer ends of the fingers swing, when they are moved upwardly.

When the fingers are in their normal position, (Figure 1), the'outer portions thereof are comparatively close together. When the outer ends of the "fingers are swung upwardly, since both'sides of each finger are curved, there will be no danger of binding. If one finger swings upwardly relative to' the adjacent finger, this will also not cause binding thereof. For instance, if the finger 22 which is adjacent the flange 17 remains in position and the finger 22 adjacent thereto swings upwardly, the outer end thereof will swing in an arc, but since the surface 27 of 1 the other finger is curved in the same arc through which the outer end of the adjacent finger swings, there will be no danger of these two fingers binding with each other.

The fingers 22 are provided with fiat extension members 29 which project from the rear ends thereof. These extension members are of such alength and are so disposed that they act as [stops .for limiting the upward movement of the outer ends of the fingers. When the fingers have moved upwardly to such an extent that the lower ends of the downwardly projecting portions'2 i are inalignment with the plate 19, the fiat extension members 29 contact with the rear edge of plate 19 and prevent further upward movement of the fingers. Thus, movement of articles back between the outer ends of the fingers and the upper surface of plate 19 is precluded. This prevents lodging of the articles between the fingers and the upper surface of plate 19, which would preclude the return of the fingers to their normal position. Furthermore, this eliminates any possibility of the fin-- gers being swung completely around the pivot point 21, to a position on the otherside of such pivot where they would rest upside down on the plate 11 and would be inoperative.

The vender lever plate? is also provided with a guard member 28 projectingupwardly therefrom. This guard member 28 normally occupies a position adjacent the downwardly extending portions 24 of the fingers 22. The guard 28 projects up into the chamber between the flanges 17 and 18. The upper end of the guard terminates at a pointslightly below the under surface of plate 19. As will be understood hereinafter, when the vendor lever plate 7 is moved back and forth the member 28 moves back and forth in the chamber 20. This member 28is provided for a purpose which will be hereinafter explained. The chamber 20 extends past the rearwardmost side of discharge opening 4 so that the measuring pocket 6 in the vender lever plate can be moved into alignment therewith, (Figure 6).

In the operation of my device, the various parts of the machine will occupy the position shown in Figure 3. The measuring pocket 6 of the vender lever plate will be filled with the articles to be vended andsome of them will project above the upper end of said pocket into the aperture 16 formed in the top plate 11. When a suitable coin is inserted into the machine, the vender lever plate may be rotated in the direction indicated by the arrow in Figure 5. Rotation of the plate '7 causes the articles projecting above the measuring pocket 6, and which are wedged therein, to contact with the lower ends of the downwardly projecting portions 24 of the fingers 22. 40

,, projecting above such measuring pocket and which are wedged tightly therein, are vended from the machine.

Continued movement of the plate 7 causes the measuring pocket 6 to be moved over the discharge opening 4 in the plate 3 which forms the bottom of the bowl casting 1. The articles will be discharged through this opening and will pass through the discharge chute to a point where they may be recovered by the operator of the machine. The weight of the fingers is sufiicient to cause them to return to their normal position after the projecting articles have passed therebeneath, to prevent discharge of any additional articles.

It will be understood that if the vendingmachine were shaken vigorously up and down when the parts are in inoperative position, the fingers might be moved upwardly so that articles in the machine could pass therebeneath. To prevent the passage of such articles over into the discharge opening 4, the guard member 28 is provided.

In Figure '7, I have shown a modified form of my invention. This modified structure is practically identical with the structure shown in Figures 1 to 6 inclusive. However, in this instance,

the guard member28is eliminated. Coil springs 30 are mounted-in a suitable manner between the flat extensions 29 and the surface of the base plate 11. These springs are adapted to return the fingers totheir normal position after they have been swung upwardly. Furthermore, the springs will guard against upward movement of the outer ends of the fingers caused by shaking the machine vigorously up and down.

It will beunderstood from the above description that I have provided a machine which is extremely simple in structure and which is eifec tive to vend'articles of irregular shape. This machine is of such a structure that clogging of the articles between the top plate, and the vender lever plate will be effectively prevented. Furthermore, the machine is capable of vendingarticles which are easily broken without breaking up such articles. pivoted fingers up and down agitates the articles in the machine. j
