GEBERT, F WILMETTE, ILLINOIS, ASSIGNORS TO ADVANCE MACHINE COMPANY OF CHICAGO, ILLINOIS, ACORPORA- ron OF ILLINOIS VENDING MACHINE Application filed September 29, 1930. Serial No. 484,957.

This invention relates to improvements in vending machines of the type inwhich there is provided a plurality of article or commodity holders from which the articles are independently dispensed by means of ejectors in dividual to the holders, and an actuating mechanism which is common to all of the ejcctors, and one of the objects of the invention is to provide improved means for selectivelyrendering the ejectors active and inactive with respect to the said actuating mechanism. I

A further object is to provide in a machine of this character improved means whereby after one of the ejectors has been set or rendered active with relation to the actuating means, it will not be possible to,

set or render another ejector active without rendering inactwe the e ector that has been previously set or rendered active, thereby rendering it impossible to operate the mastruction, and which will be effective and efficient in operation. v

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement ofthe several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention, and in which Figure l is a front. elevation of a portion of a machine of this character constructed in accordance with the. principles of this invention.

Figure 9 is a view similar toFigure 8, showing the par ts in another position. v

Referring more particularly to the drawings the numeral 10 designates generally a portion ofa casing in whichis arranged the commodity or article holders 11, any number of which may be provided. The numeral 12 designates a supporting structure upon which the operating mechanism of the machine is arranged and which structure with the operating mechanism thereon is adapted to be removed as a unit from the casing 10.

Mounted upon the supportingstructure 1 2 are a pluralityof ejectors for dispensing the articles from the respective holders or containers 10. Any number of these eje ctors and containers may be provided, andin the present form' of the invention four are illustrated. Suflice it to say, however, that one ejector mechanism is provided for each of the holders or containers 11.

As the construction and operation of each of these ejectors is the sanie,the specific description of one will apply equally as well to them all. p

Mounted upon the supporting structure and connected to this shaft are arms 14, which 12 to extend thereacross is a rock shaft 13 latter constitute means for assisting in sup:

porting and guiding the ejector mechanism, one of the arms being provided for each of the ejectors. I

Each of the ejectors consists preferably of a body portion15 provided with-flanged ed as at 17 (see p articularly Figure 4:), so as sides 16. Each of the flanges 16 is bifurcatto stand astride of the shaft 13 and is adapted for a free sliding movement in a direc tion transverse to the longitudinal axis of the shaft.

By arranging the arms 14 inside of the respective flanges 16 and by securing the arms to the shaft 13, it will be manifest that the ejectors will be held against movement in directions lengthwise of the shaft.

The ejectors are connected with the respective arms 14. by means of fastening devices or screws 18 carried by the arms and which pass through slots 19 in the respective flanges 16. The flanges preferably extend below the body portion 15 and the lower extremity of the ejector is bent or curved under the shaft 13 as at 20,- for a nirpose to be later de scribed.

The ejector preferably embodies an article engaging section 21 connected to the upper extremity thereof preferably by means of a pivot 22, and a spring23 is provided which tends normally to maintain a. portion 24. of the section 21 against the body portion of the ejector 15, so that the section 21 will be locked or maintained against movement in one direction about its pivot 22 when the parts assume the position as shown in Figures 3 and 4, but the spring 23 will yield to permit the section 21 to move about its pivot upon the return movement of the ejector so as to permit the section 21 to fold with respect to the body portion of the ejector so as to pass under the articles 25 in the container.

The weight of the ejector is such that it will normally assume the position shown in Figure 3 with respect to the shaft 13 and the bottom of the container 11. That is, in a retracted or inactive position so that upon oscillation of the shaft 13 the ejector will be inactive with respect to the articles 25 in the container 11.

One of these ejectors is mounted below each of the containers 11 and the containers are arranged above a support 26 upon which the articles 25 rest. The support 26 is provided with slots 27 through which the arms or eX- tensions 28 on the section 21 of the ejector are adapted to move, as shown more clearly in Figure 2.

The shaft 13is adapted to be rocked in any suitable manner, but preferably through the medium of a coin controlled mechanism, any form of m echanism being suitable for the purpose, one form of such mechanism being shown in Figure 7 but which mechanism constitutes no part of the present invention.

Sulfice it to say that the coin controlled mechanism is provided with an operating handle 29 which is adapted, through suitable intermediate mechanisms, to impart a rocking movement to a member 30 upon the insertion of a coin into the coin carrier 31. The rocking member 30 is connected by means of a link 32 to an arm 33 secured to the rock shaft 13, so that upon each rocking movement of the member 30 the shaft 13 will be rocked forwardly and backwardly and with it the ejectors 15.

Arranged beneath the shaft 13 and journaled in suitable supporting bearings is a shaft 34 which is parallel with the shaft 3 and seemed to the shaft 34 are a plurality of cam devices 35, one of which is arranged beneath the curved extension 20 of he ejec tors 15.

The cams 35 are arranged at different angles with respect to each other and about the shaft 3 1, so that when one of the cams 35 is positioned by the rotation of the shaft 34 so that the curved extension 20 of the respective ejectors 15 contacts and moves over the cam by the rocking of the shaft 13, that respective ejector will be prevented from maintaining an inactive position with respect to the articles 25, an d will be positioned into an active position so that when the shaft 13 moved in one direction the extensions 28 on the section 21 of the ejector will engage behind the lowermost article in the respective container and eject the article from the container and discharge the same into a chute 3G to be delivered to the customer through an opening 37.

hen the shaft 3 1 is further rotated to position another cam 35 so as to cause its respecti \e ejector to be rendered active with re spect to the articles, the cam of the already active ejector will be positioned so as to allow the ejector to drop by gravity or to be moved into an inoperative position with respect to the articles.

It will therefore be manifest that by adjusting the shaft 34, the ejectors may be selectively rendered active and inactive and the cams 35 may be arranged at any desired angle about the shaft 3 1 with respect to each other.

When the respective ejecto-s are set, and when they are partially advanced, it will be manifest that the extensions 28 will engage behind the lowermost article in the respective container 11 and as the articles to be vended are the bottom articles of the pile, the end 28 of the ejector which has been set will contact with the edge of the article. It has been found that by a skillful manipulation of the machine any one of the ejectors when moved to this position, may he made to retain such position while another ejector is selected and rendered active so that upon a further operation of the machine or rotation of the shaft 13, both of the ejoctors will deliver an article from the machine, thereby causing two articles to be delivered instead of one.

This is objectionable, and therefore in order to overcome this objection and to provide a means for rendering inactive the ejector which has been previously set, by rendering active another ejector, means are provided for positively withdrawing the set ejector.

This may be accomplished in any desired or suitable manner, but a simple and efiicient means embodies an arm 38 (see particularly Figure 4) ,which is secured to the body portion 15 of the ejector. This arm is secured as at 39 to the body of the ejector and is provided with a portion 40 which depends below the shaft 13 and is bifurcated as at 41 so as to stand astride of the shaft 34, to which the cams 35 are secured. This arm 401s provided with a laterally projecting portion 42, preferably at the lower end thereof, and on eachside of the bifurcation. A cam 43 is secured'with the cam 35 for rotation therewith, and this cam 43 is so positioned that it will engage the lateral projection 42 on the arm 40, a portion of the cam 43 being removed or flattened as at 44. I The cam 43 is so positioned with respect to thecain 35 that the flat portion 44 of the flange 43 will be disposed in proximity to the flange 42 when the cam 35 is positioned to be active, that is, is moved to a position that when the portion 20 of the ejector 15 rides thereover the ejector will be projected or moved into operative or set position so that the portions 28 will pass through the slots 27 in the support 26 and engag behind the lowermost article in the supply.

When, however, the shaft 34 is rotated so as to move one of the cams 35 into a position that the respective ejector will thereby be rendered inactive, the high portion of the cam 43 will commence to act upon the flange I 42 of the arm 40 and thereby draw the arm 40 and the member 15 downwardly or into an inactive position. i

In other words, the cams 43and 35 are so arranged with respect to each other that when one is in an active position to act upon its corresponding part, the other will be in a position to render its corresponding mechanism inactive.

I11 order to select the container from which the article is to be vended, it is only necessary 7 Connected with the handle 45 is a shaft 46 and connected with the shaft 46 is a gear 47, preferably of the beveled type which meshes with a gear 48 which in turn is secured to the shaft 34 for rotation therewith. Thus by rotating the handle 45 the shaft 46 will be rotated and this will in turn rotate the shaft 34.

45, and which indicator co-operates with suitable graduations or indicator marks 51.

As a means for assisting in 'posltionlng the shaft 46 against retrograde movement, there may be provided a disc 52 secured to the shaft I and which is provided "with shoulders 53, with which shoulders apa'wl 54 pivotally mounted as at 55 cooperates,'and a spring 56'tends normally to move the pawl 54 into a position to be engaged by the shoulders 53.

It is thought that theioperation of the mechanism will be clearly understood from the foregoing, but'briefly stated, it is as folows. 1

The handle 45 is first operated to select the container from which it is desired to dispense the article, and this is accomplished by rotating the handleto position one of the cams 35 to render its respective ejectoractive. As soon as the shaft 34 is rotated, any ejector which has been previously set or which has remained active will be rendered inactive by reason of the fact that one of the cams'43 will operate upon the arm 40 of that ejector which has been previously set, so as to wit! draw or move the latter into an'inactive position. At the same time the fiat portion44 of the cam 33 of the ejector which it is desired to renderactive'will have assumed it position with respect to the flange'42 so as to permit the respective cam 35 to raise the body portion 15 of the ejector that it is desired to set, with respect to the shaft 13 and the arm 14.

The coin is then depositedin the coin carered into the machine, causing the member 30 to be rocked when the handle 29 is rotated in the opposite direction. By rocking the member 30 from the position shown in Figure 9, to the position shown in Figure 8, the shaft 13 will be rocked, as will also the ejectors 15. I

When the parts are moved from the position shown in Figure 9 to the position shown in Figure 6, the cam 35 which is individual to the ejector of the selected container will 1 2 be rendered active by reason of the curved portion 20 of the ejector engaging and riding over the respective cam 35, thereby causing the ejector to be bodily moved with re spect to the shaft 13 and with it the arm 40, 25

positioning the extensions 28 of the section 29 of the ejector back of the lowermost article 25. The ejector will be held in this position until the parts are moved to the position shown in Figure '8, that is the ejector will be held elevated with respect to the shaft 13 by the respective cam 35.

When the shaft 13 is rotated in the opposite direction so as to move the parts from the position shown in Figure 8 back to the position shown in Figure 9, the section 21. of he elevated or active ejector will contact with the lowermost article 25 in the container 11 and will yield during the return movement of the ejector, about its pivot 22 against the stress of the spring 38 so as to permit the extension 28 to pass under the article. soon as the ejector has assu med a position that the extensions '28 will be positioned in front of the lowermost article, the spring 23 will cause the section 21 to assume its normal position as shown in Figures 3 and i.

7 Thus it will be manifest that the device may be selectively controlled by operating the handle 38.

It will also be manifest that when one of the cams is positioned to render its ejector active the cams 43 of the other ejectors will be actuated so as to operate upon its respective arm 4:0 and thereby witl'ujlraw or remove to an inoperative position any ejector which has been previously set.

As a means for assisting in posiitionin the shaft 34 and the cams 35 as well as the cams 43 by the adjustment of the handle a5, a resiliently yielding locking device may be provided on the shaft 34.

Any suitable means may be provided for this purpose, but a simple and etlicicnt means embodies a disc 57 provided with cam portions 58 having recesses 59 in its periphery. A lever 60 is pivotally mounted as at 61 and. is provided with an anti-f1:'iction roller or projection 62 adapted to enter the recesses 59, and a spring 63 tends normally to move the lever 47 in a direction that the projection or anti-friction roller will engage the peri ph cry of the disc 57 Thus by rotating the handle the lever 60 will yield to permit the shaft PA- to he rotated and the anti-friction roller or projection 62 will, under the influence of the spring 63 enter one of the seats 59 as the latter approaches the projection or roller.

While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangen'ient of the several parts, within the scope of the claii'ns, without departing; from the spirit of this invention.
