Description:

My invention relates to new and useful improvements in vending machines.

An important object of my invention is to provide a vending machine that is adapted to contain a plurality of small articles such as aspirin, gum or the like, and to individually or seriately discharge the same to the customer.

Another object of my invention is to provide a vending machine that is light and compact in its construction, and that may be placed in any convenient location that is readily accessible to potential customers.

Still another object of my invention is to provide a vending machine that is adapted to operate upon the deposit of a coin in the device and that will automatically return the desired article to the customer.

Another object of my invention is to provide a vending machine that will require very little supervision or attention after it has been filled with the articles to be vended.

A further object of my invention is to provide a vending machine that is simple in construction, efficient in operation and inexpensive to manufacture.

Other objects and advantages of my invention will be apparent during the course of the following description.

In the drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the sameFigure 1 is a vertical sectional view of a device embodying my invention, Figure 2 is a longitudinal sectional view taken on the line 2-2 of Figure 1, Figure 3 is a transverse sectional view, taken on the line 3-3 of Figure 2, and showing parts broken away, Figure 4 is a front elevation of my device, and SFigure 5 is a top plan view of the agitator plate embodying a part of my invention.

In the accompanying drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral 10 designates a box-like receptacle which includes a base member II, rear and front walls 12 and 13, side walls 14 and 15, and a removable cover 16. The supporting blocks 17 and 18 are mounted interiorly of the box and in appressed relation with the inner face of the sides 14 and 15. The upper face 19 of the block 17 is bevelled toward the inside of the receptacle, and the upper face 20 of the block 18 is similarly bevelled but at a greater angle so that the inner rectilinear edge 21 of the face 20 is disposed substantially lower than the corresponding rectilinear inner edge 22 of the block 17.

A slug proof coin slide 23 of conventional construction, is carried by the front wall 13 of the receptacle and the slide bar 24 thereof operates interiorly of the receptacle. The upper portion of the block 18 is of reduced thickness to define the longitudinally extending horizontal shoulder 26 and the inner face of the projecting lower portion 27 thereof is provided with an angularly disposed groove 28 the upper end of which opens through the shoulder 26 substantially one-third of the way from the rear wall 12, and the lower end thereof communicates exteriorly of the receptacl& through the front wall 13. The basin 29 is carried by the base 1 under the outlet end of the groove 28 to receive the vended articles discharged therethrough. The cover plate 30 is carried by the block 18 and encloses the inclined groove 28.

The discharge plate 31 is carried by the inwardly extending end of the slide bar 24 and has one longitudinal edge slidably received within the recess 25 in the block 17 and the other longitudinal edge supported on the shoulder 26 of the block 18. The rear edge 32 of the discharge plate extends rearwardly of the said slide bar but terminates a substantial distance from the rear wall 12, and an integrally formed lateral tongue 33 extends forwardly along the slide bar and with its forward end 34 normally positioned adjacent the front wall 13 of the receptacle when the slide bar 24 is in the fully retracted position.

The lateral recess 35 in the discharge plate is of substantially the same size as the article to be vended, which is here illustrated as an aspirin.

The recess 35 is therefore substantially rectangular in shape and is slightly larger than the ordinary aspirin, and when the slide bar 24 is in the innermost or advanced position, the recess 35 is adapted to communicate with the upper end of the inclined groove 28 in the block 18.

An agitator plate 36 is supported by but not attached to the discharge plate 31 and either side thereof slidably engages the inner faces of the blocks 17 and 18. The side 37 of the agitator plate is provided, with a lower longitudinal recess 38 which overlies an upwardly extending shank 39 carried by the discharge plate 31. The spaced pins 40 and 41, are carried by the plate 36 and extend laterally through the recess 38 to be alternately engaged by the vertical shank 39 when the slide bar 24 is reciprocally actuated.

The upper face 42 of the agitator plate is bevelled so that the rectilinear edges 43 and thereof will be positioned in aligning relati( with the rectilinear edges 22 and 21 of the blocd 17 and 18. The side 45 of the agitator plate provided with an elongated recess 46 of substai tially the same width as the recess 35 in the di charge plate 31 and of sufficient length to accon modate several of the articles to be vende Transverse closure walls 47 and 48 are positione above the agitator plate 36 and are support( in aligning slots in the blocks 17 and 18 to dm fine a central space within the receptacle bounc ed by the upper face of the agitator plate 3d upper faces 19 and 20 of the blocks 17 and IU and the top cover 16.

The operation of my device is as follows: When the slide bar 24 is in the fully retracte( or coin receiving position, the discharge plate 3 will be positioned forwardly in the receptacl and the vertical shank 39 carried thereby wil be in engagement with the lateral pin 40 to mov the agitator plate 36 forwardly in the receptacl so that the forward edge thereof will be adjacen the front wall 13. The articles to be vended ar deposited between the transverse walls 47 and 48 and by virtue of the inclined nature of the uppei surface 42 of the agitator plate, several of the said articles will fall within the elongated slot 46 The slot is here illustrated as adapted to accommodate four aspirin, the foremost of which will drop into the aligning slot 35 of the discharge plate 31. When the coin is inserted in the coin slide, the slide bar 24 may be pushed inwardly into the receptacle and the article within the slot 35 will be moved rearwardly until it moves into alignment with the upper end of the inclined groove 28 in the block 18. The vertically extending shank 39 of the discharge plate will engage the rear laterally extending pin 41 of the agitator plate before the recess 35 aligns with the groove 28 to move the said agitator plate a slight distance rearwardly therewith and to jar the same in a manner to cause another of the said articles to be deposited within the elongated slot 46. When the slot 35 in the discharge plate is in alignment with the upper end of the inclined groove 28 it will be disposed rearwardly of the elongated slot 46 in the agitator plate, and the article ositie ioned therein will drop into the inclined groove 28 and roll downwardly therein and into the basin 29. Upon forward movement of the slide bar, the discharge plate will move forwardly in a manner to bring the recess 35 into alignment with the elongated slot 46 in the agitator plate to receive another of the articles positioned therein. Shortly before the coin slide is in the fully retracted position the shank 39 will engage the foremost pin 40 of the agitator plate to move the same forwardly and to jar another of the articles into the elongated slot 46.

It may thus be seen that upon full retraction of the slide bar 24, the device will be again fully loaded and ready to discharge another article upon the insertion of another coin in the coin slide. Because of the inclined upper surface 42 of the agitator plate and the jarring motion which it receives upon every actuation of the coin slide, the articles within the hopper will be entirely discharged from the machine before refilling is required.

It is to be understood that the device is not restricted to aspirin, but may be used to vend any small article of uniform size. The form of the invention herewith shown and described is 44 to be taken as a preferred example of the same, on and various changes in the size, shape and arks rangement of parts may be resorted to, without is departing from the spirit of my invention, or the i- scope of the appended claims. s s- Having thus described my invention, I claim: 1- 1.
