4 Claims.

This invention relates to the art of vending machines of the type for vending commodities in uniform packages. Aprimary object of the invention is to provide a simple structure where- 5 in a large quantity of packages may be stored and vended one at a time from a unit occupying very little space.

A further primary object of the invention is to provide means for vending a similar package 19; one at a time one after another from a plurality of columns of packages stacked one above the other whereby one entire column is emptied before packages are vended from the next adjacent column. I

These and other objects and advantages of the invention will become apparent to those versed in the art in the following descriptions of the invention as illustrated in one particular form in the accompanying drawings, in which Fig. 1 is a top plan view of a structure embodying the invention;

Fig. 2 is a vertical longitudinal section on the line 2-2 in Fig. 1;

Fig. 3 is a detail in vertical section on the line 33 in Fig. 2;

Fig. 4 is a detail in top plan View of the actuating mechanism;

Fig. 5 is a detail in side elevation in partial section of the actuating mechanism, and.

Fig. 6 is a detail in transverse section on the line 6-'6 in Fig. 4.

Like characters of reference indicate like parts throughout the several views in the drawings.

A base Ill is provided with a removable floor II normally secured to the base in closed position by telescoping up over the lower ends of the base side walls to have a pin l2, Fig. 2, extend from an upturned flange on the floor through a hole in an end wall of the base and to have a bolt I3 pass up through the floor to screw-threadedly engage a bracket [4 carried by the base. Preferably the base is recessed as indicated in Fig. 2 toreceive the head of the bolt l3 and permit the base It to stand on any suit- 45 able table, counter or the like in a level position.

On the top of the base H] is mounted a magazine I5 for carrying the goods to be vended. This magazine in the form herein shown consists of a rectangular box divided into a number of vertical compartments herein shown as five in number by means of the transversely disposed partitions IS. A removable magazine cover I! is provided to fit over the top end of the magazine and is normally retained in position by means of the screw l8 passing through the cover l1 and engaging a bracket [9 carried by an end wall 20 of the magazine. It has a pin l2 from a downturned flange on the cover through a hole in an end wall of the magazine l5, similar to the pin 2 of base II and for a like purpose.

The top of the base I0 is cut away centrally under the magazine in the form of a longitudinal slot 2|, the slot being out to leave flanges or tracks 22 and 23 along the underside of the magazine IE on which the columns of packages 24 normally rest.

At the left hand end of the slot 2|, a communicating opening. 25 is provided in the top of the base ll] of a sufiicient width and length as will permit an individual package 24 to be 15, dropped therethrough when that package is pushed suiliciently far to the left to leave the ends of the tracks 22 and 23. An enclosure 26 is provided over this opening 25 in the form of a rectangular box as indicated in Figs. 1 and 2.

Immediately under the opening within the base I2 is mounted an inclined floor 21. This floor 21 is continued downwardly and outwardly through an opening 28 in the end wall of the base It] and terminates exteriorly of the base by an 25 upturned flange 29 whereby a package 24 dropping through the opening 25 will drop down on to the floor 21 and slide outwardly through the opening 28 to come to rest against the flange 29, Fig. 2.

Immediately under the slot 2| is mounted a U-shaped trough 3|], Fig. 3, to have the upturned ends of the trough secured to the underside of the tracks 22 and 23 respectively by any suitable means such as by welding. Within this trough 30 is a slide 3| freely shiftable along the trough. This slide 3| is likewise U-shaped in cross section and is turned with the open side upward to carry a plurality of ejector dogs 32, here shown as five in number, one for each 001- umn in the magazine. These dogs are rockable upon transverse pins 33 extending between the legs of the slide 3|. These dogs are mounted sothat they will normally rock downwardly by their right hand ends to have the other ends turned upwardly as indicated by that dog to the extreme right, Fig. 2. In the form herein shown, each dog is a U-shaped member having the cross or tie bar on the right hand side to act as a weight to rock the dogs as above indicated. The pins 33 carrying the dogs are located on the slide 3| such that when one pin is centrally positioned under one of the magazine columns the next adjacent pin will likewise be centered under the next adjacent column.

As indicated in Figs. 1 and 2", the magazine housing is made to be of suflicient length as will permit a space 34 between the last vertical partition l6 and the wall 20. This space is provided to permit the dog 32 at the right hand end of the carrier 3| to rock normally to tilt its left hand ends upwardly to the right of the package 24 appearing at the bottom of the first column. When the slide or carrier 3| is moved to the extreme right hand position to permit this automatic positioning of the right hand dog 32, the

other four dogs 32 are held against rocking by reason of their free ends bearing against the undersides of the packages 24 appearing in the various columns thereover. Also when the carrier 3| is in that position, there is no dog under the last or left hand column of packages asindicated in Fig. 2.

Now when the slide 3| is pushed to the leftlin the trough 30, the tilted dog 32 will come into contact with the end of the package 24in the right hand column. Since the other end of the dog bears against the bottom of the slide 3|, the dog can rock no further and therefore serves as a means for pushing against the package 24. Continued movement of the slide 3| will carry that end package against the next succeeding package and so on until the package 24 at the bottom of the extreme left hand column is pushed on over the hole 25 and drops therethrough to be discharged down the incline 21. At this position, the end of the slide 3| will strike the, end of the incline 21 and prevent further travel. Of course packagesin the extreme right hand column will drop down the distance of one package behind the pushing dog 32 to present a package in that column in front of the right end dog 32 for the next operation. Return movement of the slide 3| is madein which case the dogs 32 will a slot 36 in the top of the base.

slide back under the various packages without causing any movement thereof and the right hand dog 32 is again brought to the operating position as before.

After all of the packages 24 have been removed the dog 32 under that column will then turn upwardly and act as the ejecting member by pushing on packages dropping down in the nextadjacent column to the left. This action is repeated for each of the various columns as they empty. In order to control the movement of the slide. 3|, an external handle 35 is provided, here shown as extending vertically from the top of thebase IE] to have a shank extending through This shank 31 is secured to a slide plate 38. This plate has an opening 39 provided therein which will register under the opening 40 in the top of the base I!) when the handle 35 is pulled to the right hand end of the slot 36. Under the slide 38 is a plate 4|. slidably mounted on a bracket 42 which is supported by the base ID. This under slide 4| is interconnected with the slide member 3| by the finger 43, Fig. 4.

The slide member 4| is provided with a major opening 44 of sufiicient size as will permit a coin 45 to be dropped through the hole 40 of the base and through the hole 39 in the plate 38. The plate 38 is provided with a pair of downturned fingers 46 and 4'! which enter within the hole 44 in the plate 4| and when the coin 45 is pushed in the hole 44, these two fingers 43 and 41 will push against the coin and the coin in turn will push against the side of the hole in the plate 4| and thereby through travel of. the handle 35 shift the slide or carrier 3| to cause ejection of a package 24 in the manner above described. When there is no coin 45 in position as indicated, the two fingers 46 and 41 will travel freely through slots 48 and 49 entering the slide 4| from the hole 44. Thus when there is no coin, there will be no travel of the slide 4| regardless of movement of the handle 35 back and forward. Under the slide 4| at the left hand end of travel is a'hole 50 through the bracket 42 which will permit the coin 45 to drop on down into the base ID to rest on the floor II when the handle 35 is released or is started in the right hand direction. Continued movement of the handle 35 in the right hand direction will cause the fingers 46 and 41 to be brought against the right hand edge of the hole in the plate 4| and thereby carry the plate 4| back to in turn bring the carrier 3| to its right hand position.

While I have herein shown and described my invention in the one best form .as now known to me,,it is obvious that structural variations may be employed without departing from the spirit of the invention and I therefore do not desire to be limited tothat precise form beyond the limitations as may be imposed by the following claims.

I claim:
