7 Claims.

This invention relates to a device for dispensing and vending individual articles of merchandise, such as merchandise packages, books and the like.

The invention is a continuation in part of our copending prior patent application Serial No. 572,220, filed January 10, 1945.

A dispensing device is disclosed in this copending patent application, where the individual articles to be dispensed are supported on trays which are located within a housing in horizontal rows and in vertical banks; a pusher correlated to each tray is provided to advance the articles to a place of delivery; the pusher is actuated by electrically motivated and controlled means and is rendered inoperative when a package passes and is discharged at the front portion of the tray, whereby further advance of the articles is interrupted.

It is the object of this invention to prevent the accidental discharge of the articles and to assure proper discharge of the articles to a place of delivery.

It is a further object of the invention to afford the direct viewing and the selection of a certain desired articleand to, therefore, enable the purchaser to see what he buys.

It is another object of the invention to simplify the construction of the dispenser disclosed in our co-pending U. S. patent application and to secure its reliable unobstructed operation.

Additional objects achieved by the invention will become apparent as this specification proceeds.

. The invention will now be described in detail with reference to the accompanying drawings illustrating a preferred embodiment of the same which is particularly useful for the vending and dispensing of rectangularly shaped goods, for instance, books.

In the drawings,

Fig. 1 is a front elevation of the dispenser;

Fig. 2 is a vertical sectional elevation on line 2'-2 of Fig. 1;

Fig. 3 is a horizontal sectional elevation on line 3-3 of Fig. 2;

Fig. 4 is a vertical sectional elevation on line 4- i of Fig. 3 and Fig. 5 is a further modification of a constructional detail shown in Figs. 3 and 4.

The dispenser housing is denominated in the drawings by the letter A. Its inner space is subdivided into two lateral compartments B, a central compartment E and a bottom compartment D. The twov lateral .Compartments B accommodate the articles a, Figs. 2, 3, 4, which are adjacently stacked on pairs of spaced parallel angle irons 3|; in this manner the compartments B are subdivided into a plurality of article carrying tracks or passages extending through the greater part of the width of housing A.

The front ends of angle irons iii are joined to lips extending transversely of the housing A, the lips being supported in the outer housing walls in any convenient manner. The uppermost lip l is supported in spaced relationship to the uppermost row of pairs of angle irons 3i.

The articles, a, rest on the smaller flanges of the spaced parallel angle irons 3i and they are held in their upright position by the larger flanges.

A pus-her 2 is slidably mounted on the angle irons 3| and may be advanced to advance the articles, a, on the tracks formed by the flanges of the two angle irons 3!. I

A pulley 4 is mounted on and below each track at the underside of the front end of the same and a rope 3 runs over the pulley. One end of the rope is fastened to the lower part 33 of pusher 2 and the other end is connected to one of the sleeves l'l, Fig. 2. Each pusher 2 is connected to a different corresponding sleeve l! and is driven independently of all of the other pushers. Only one of the pusher and sleeve driving systems will be described herein, it being understood that all of the other driving systems are the same. The sleeve is a part of a driving assembly which advances the pusher 2. This assembly is operated from motor I! through the intermediate action of shaft I 2. The rotation of shaft I2 is transmitted to transmission gears of customary construction housed in gear chamber l3; shafts l0 entering gear chamber it from above are continuously driven by these gears; the rotation of shafts H1 is transmitted to sleeves I! by an oscillating pawl and rotatable ratchet drive only upon the actuation of push buttons 2!, which close an electric circuit which energizes a solenoid to cause the oscillating pawl to engage the ratchet and thereby rotate the sleeve H, as described in detail in our co-pending application Serial No. 572,220. Accordingly, pusher 2 is only advanced when its correlated push button 2| is actuated.

If, therefore, the electrical circuit is closed by actuating push button 2|, sleeve ii of the selected track is rotated; the correlated rope 3 is wound upon the sleeve and advancing pusher 2 moves the articles, a, towards delivery chute 8. When the front article during the advance by pusher 2 reaches the end of the supporting passage, it will have the tendency to topple over; the articles following the front article, which are now not any more held by mutual contact in the upright position may follow the first article in the tendency to topple over. To remedy this situation discharge lips I are. provided which extend in a transverse direction through housing A. These lips are so shaped as to engage the upper end to prevent the articles, a, from toppling over and to maintain the same in an inclined position; Figs. 2 and 4.

To avoid the clogging of the inclined articles, which would interfere with the proper action of pusher 2, an arrangement is provided which will now be described.

A restricted number of articles located next to and behind the inclined front articles are held in the original straight upright position. This is achieved in the present embodiment of theinvention by springs l4. These springs are carried by brackets 15 fastened to lips I. The operative ends of springs, l4 are bent inwardly to permit an unobstructed. entrance. and exit of the articles therebetween and from the same. Due to the resiliency of springs i l the articles approaching the discharge end of the passages are kept in vertical position, only those front articles which are released from the grip of the springs by the pusher, being permitted to assume the inclined position shown in Figs. 2 and 4. They are, however, prevented by lip I from toppling off the end of the support. The article thereby remains on the support in an inclined position until the pusher advances the lower edge of the article a sufiicient distance to slide it off the end of the support whereupon the article drops by gravity and: is discharged.

Thus the discharged articles slide over lip l into discharge chute 8 avoiding, clogging. They fall freely into inclined delivery chute 34 and arrive finally on: platform 35 from where they may be picked up by the purchaser.

A devicefor stoppingthe advance of the pusher consisting of a normally closed switch 24 is fastened' to the forward end of each track, as also described in our co-pending' application Serial No. 527,220. The switch is in a customary manner provided with a resilient contact tongue 9 projecting through an opening 4| of lip l, Figs. 1', 4.

A package pushed from the platform strikes against the resilient tongue 9. The latter opens the switch which will interrupt the circuit closed by theactuation of apush button and stop further advance of the pusher in a manner described in detail in our co-p'ending application Serial No. 572,220. After the package has been discharged from. the track, tongue 9 returns to its former position and the switch is closed.

In the present exemplification of the invention forty passages or tracks. are provided in housing A.. Each. chamber B contains twenty pairs: of tracks, while center compartment E accommodates the pusher driving assemblies correlated to the individual passages. The driving assemblies arranged in compartment E are hidden from direct sight: by'front wall It. The passages are in the same manner as the trays of our co-pending' application arranged in horizontal rows and in, vertically superposed banks.

Another important. feature of. the invention consists in the. construction of the front wall of housing A.

Aspreviously stated. themerchandise or articles to be sold are displayed in the instant vending machine on a plurality of tracks arranged in horizontal rows and vertical banks.

It is of decisive importance in such an arrangement that the merchandise is visibly displayed so that each article can be seen individually and selected accordingly. For this purpose a window 22 is provided which has a frame 23, the latter being removably inserted in the front wall of housing A.

Push buttons 2| mounted in the window pane are in correlation with the individual tracks. Thus, if a push button placed in front of a certain article is pressed, the pusher of this same track is actuated and will move the merchandise forward, as described above, so that it drops out into chute 8.

The coordination of each push button in front of the merchandise which is clearly visible to the customer is of the greatest importance. Visibility in selling, sales identification. of the merchandise without inscription, are decisive advantages.

Another modification of the merchandise selecting arrangement is shown in Fig. 5; in conformity therewith transverse struts 25 are arranged in front of the glass pane 22; the push buttons 2! are mounted on these struts. If desired, the window pane 22 may be subdivided in sections in conformity with the number of the horizontal rows of tracks and the struts may then be used to support the window sections.

As many changes could be made in the above construction of a vending machine and many apparently widely different embodiments of this invention could be made without departing from. the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and without limitation of the invention.
