9 Claims. 1

The present invention relates to vending machines. One of the objects of the invention is the provision of a machine of this character having a movable magazine or article holder wherein movement of the article holder will efiect discharge of the articles therefrom.

A further object is to provide a vending machine of this type wherein the act of inserting a coin will eiiect initial movement of the article holder in its vending operation.

Another object is to provide a two step discharge of the material, the first step being performed during initial movement of the holder, while the second step takes place during return movement of the holder to its original position.

A further object is to provide a construction of this character wherein the coin not only effects initial movement of the holder, but also controls means for permitting return movement of the holder to its original position.

With the foregoing and other objects in view, the invention will now be more fully described, reference being had to the accompanying drawings, in which:

Figure 1 is a front elevation of the vending machine,

Figure 2 is a vertical section taken on line 2-2 of Figure 1,

Figure 3 is a vertical section taken on line 3-3 of Figure 2,

Figure 4 is a transverse section taken on line t-i of Figure 3,

Figure 5 is a transverse section taken on line 5-5 of Figure 3,

Figure 6 is a fragmentary view showing the lower end of the article holder as it is being swung from its normally vertical position, and

Figures '7, 8 and 9 are front views of the vending machine, with th casing removed and showing the article holder in its various positions during the operation of the machine.

Referrin now to the drawings and particularly to Figures 1, 2 and 3, the numeral Ill designates generally the present vending machine having an enclosing casing H which is open on its rear side and cooperates with a vertically extending support I2 to enclose the vending mechanism. As will be observed from Figure 2, the support N forms the rear vertical wall of the casing and this wall is provided with one or more sets of clips it (see Figures 4 and 5) which receive inwardly extending flanges M of the casing II. The casing may be removed by sliding the same upwardly on the support l2 until the flanges it are moved out of contact with the clips I3.

The numeral i5 designates a magazine or article holder having a rear wall it and side walls l7 and i8, respectively. The front edge of side Wall E? is bent inwardly to form a front flange i9 and side wall it is formed in the same manner to provide front flange 26 which cooperates with the flange id to retain the articles it within the holder. The bottom wall or floor 22 of the holder is of suflicient size to adequately support the articles but this wall does not extend across the entire area of the holder. As shown in Figure 3, bottom wall 22 terminates at a point spaced from the lower end of side wall ll to form therewith an article discharge opening. Bottom wall 22 is also provided with a downwardly extending flange or finger 23 and also has a centrally disposed slot 2 which extends upwardly a short distance into side wall 58. The objects and functions of the flange and slot will be described in detail hereinafter.

The article holder i5 is pivotally mounted on the support l2 adjacent its upper end. The pivot comprises a transversely extending rod 25 having one end thereof secured to the support l2. A pair of bearings 26 (see Figure 4) project outwardly from side wall H and cooperate with the rod 25 to swingingly mount the article holder on its support it. The front wall 2? of the casing l I,

is provided with a coin slot 28 adjacent its upper end. Secured to the upper portion of the support [2 is a bracket 2Q (see Figure 2) having a downwardly extending front flange 36 which is provided with a slot 3i registering with slot 28 and spaced therefrom a distance less than the width of the coin or check which is to be employed in initiating operation of the machine.

A coin engaging arm 32 is secured adjacent the upper end of flange it and provides the laterally extending portion which normally is positioned in front of and below the upper end of slot 3% when the article holder is in its normal vertical position. The arrangement of these elements i'; such that insertion of a coin 32' in slot will engage the under side of arm 32 and raise the same, thereby swinging the arm and article holder about To assist gain the coin into the slot at the moment to the coin engages the arm there is provided lug or projection 33 secured to the front of flange 56 so that its upper is on a lev 1th the lower end of slot 35. With this arrangeme t there is no opportunity for the coin to slip dow dly before it has performed its function. of liftii V the and swinging the holder 55 about its pivot.

The swinging movement of the article holder 3 effects a discharge of the lowermost article 2| from the holder and this is performed in a two step operation. Directly below the bottom wall 22 of the holder is mounted an article receiving shelf 3 3 which is supported on the base of the support Hi. This shelf comprises an upwardly projecting wall 36 which cooperates with a curved casing 3'? to house a post 38. This post projects upwardly through an opening in the rear of the shelf 3t and is in alignment with the slot 24 of the base 22 of the holder. A coil spring 3? is mounted in the housing below the post and engages the head 38 of the post to normally retain the post in the position shown in Figure 3.

Referring to Figure 6, it will be observed that as the holder is initially swung on its pivot by the insertion of a coin in the

slots

28 and 3|, the post 38 will contact the foremost article 2i and transfer it from the floor 22 to the shelf 34. In this connection, a leaf spring 39 is secured to the lower end of side wall I? and extends downwardly below the shelf 34. The spring engages one edge of the article as it is being moved off of the base 22 and guides it on to the shelf 34. It will be observed that when the lowermost article has been deposited on the shelf 34, the flange or finger 23 which is swung to the position shown in Figure 7 is in contact with an edge of the article. Therefore, during the return movement of the article holder, the flange 23 will shove the article oif of the shelf 34 and upon the base 35 directly in the rear of the discharge opening :30, formed in the front wall 27 of the casing ll. After the lowermost article has been deposited on the shelf 34, the next article will engage the top of the post 38 and thereby depress the same as shown in Figure '7. This action greatly facilitates the operation of the machine and assures that the weight of the article upon the post will not retard or prevent return of the holder to its original position. If the post was rigidly fixed in the housing 37, the weight of the articles, particularly when the holder was filled, might cause the top of the post to penetrate the lowermost article and thereby prevent return of the holder. It will be observed that the top of the post 38 is beveled or inclined so as to present a very small contacting surface to the article.

In order to provide a momentary locking of the holder at the end of its initial swing and to insure that the article will be properly discharged, means are provided to retain the holder in its inclined position. This means comprises a latch member :3! which is pivotally mounted on a rod t2 supported by and extending outwardly from the support i2. The latch is provided with a longitudinally extending portion 43 which is maintained in a horizontal position when the holder is in its normal position (see Figures 3 and 9). The longitudinally extending portion 43 has a notch Ml formed therein which is adapted to cooperate with pin t5 formed on the wall I! of the holder and projecting outwardly beyond the edge of the wall so that it will overlap the latch member. A coil spring it extends between the downwardly extending arm ll of the latch member and a stationary bracket A8 and urges the latch member into contact with the lower edge of the pin 45.

Mounted on the article holder at a point directly below the slot 3i of the bracket 30 is a coin chute 59. This chute is of sufllcient width to receive a coin after the latter has raised the arm 2 and swung the holder to the position shown in Figure 7. Furthermore, the free end of the longitudinally extending portion 43 of the latch member is bent at substantially right angles to the rest of the member and then bent again so that it will be directly in line with the lower end of the coin chute it when the holder has been swung to its extreme position as shown in Figure 7, thus forming a coin engageable element 50. It will further be observed that the transversely bent portion 56 (see Figure 2) acts as a guard to prevent the holder from swinging too far and possibly contacting the adjacent wall of the casing ll.

With this construction and assuming that a coin has been inserted in the coin slot, the article holder will be swung about its pivot and as it reaches the end of its swing, the pin 15 will engage the notch it and thereby retain the holder in the position shown in Figure '7. However, the holder is only momentarily maintained in this inclined position due to the fact that the coin after it leaves the coin chute will fall upon the portion 50 of the latch member and move the same about its pivot. This will release the notch 44 from the pin :25 and the article holder will thereby swing back to its normal vertical position, where it will be in position to receive another coin. As described above, the initial swinging movement of the holder will transfer the lowermost article to the shelf fi l, while the return swing of the holder will, by reason of the flange 23, shove the article ofi the shelf and upon the base 35 directly behind the opening ii! in the casing where it can be easily reached and removed.

To insure against insertion of a coin when the article holder is empty, there is provided a follower plate 5i which rides upon the topmost article and eventually moves to the position shown in Figure 9. It will be observed that the thickness of the follower 5i is greater than that of each of the articles. Furthermore, the thickness of the follower is such that the upper edge of the follower will overlap the extreme lower end of the side wall ll. Since the post 38 will be directly behind the follower 51 in the position shown in Figure 9, any attempt to insert a coin will be prevented by reason of the fact that the follower will engage the post and since it is not free to slide ofi of the base or floor 22 of the holder, because of engagement of the front wall I! with the follower, the holder will be prevented from swinging about its pivot. This will, of course, prevent the arm 32 from being lifted above the upper end of the slot 3! so that it will act as a lock to prevent insertion of a coin through the slot 3|.

It is to be understood that the tension of the spring it is such that the latch will only be tripped if a coin of suificient weight is inserted in the coin slot. Thus, if a lightweight slug or the like is inserted in the slot, an article will not be delivered even though the holder has been swung to its inclined position and the holder cannot be released until a coin of the correct dimension and weight is inserted in the coin slot. When this has been done, the coin will engage the latch member and release the holder so that it may then swing back to its normal vertical position and in doing so, will discharge the lowermost article.

It is to be understood that the invention is not limited to the details of construction shown in the drawings and that the phraseology employed in the specification is for the purpose of description and not of limitation.
