13 Claims.

This invention relates to improvements in vending machines of the type in which the supports for the articles to be vended are arranged in a column consisting of downwardly inclined supports one above the other and properly spaced to receive the articles therebetween, each support holding its respective article or commodity.

Holding means are provided which co-operate with the supports for the articles, the respective holding means when shifted, operating to release the article so that one may fall or be delivered from the support to the operator of the machine and another article will replace the one vended.

It is one of the objects of the present invention to provide improved means for holding a plurality of articles upon the same support, one in advance of the other, and improved means for successively releasing the articles to be vended, upon proper operation of the machine, thereby insuring that a sufficient supply will be held in reserve to be automatically positioned to be delivered after the delivery of the foremost article.

A further object is to provide improved means for separating the articles on the respective supports from each other and also improved means for locking the separating means against operation.

A further object is to provide improved means for actuating the said locking mechanism to actuate the separating means to release an article.

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 of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention and in which Figure 1 is a view in elevation of a portion of a machine constructed in accordance with the principles of this invention, taken on the outside of the casing.

Referring more particularly to the drawings, the numeral I5 designates an enclosing casing which may be of any desired size and configuration and constructed of any suitable material, having arranged in the bottom thereof a chute l6 upon which the articles are deposited and from which the articles are delivered through a delivery door opening I! in the front of the machine.

The front of the casing is preferably provided with a transparent portion I8 through which the articles may be viewed and the casing may be provided with a removable back or closure l3.

Within the casing are a plurality of superposed supports 2|] which preferably incline downwardly toward the front of the casing but terminate short of the front wall to form a passageway 2| into which the articles are delivered as they fall by gravity from the respective supports 2!]; and through which passageway the articles will fall until they strike a deflector 22 supported at the bottom of said passageway 2| and which extends below the series of supports to direct the articles to the chute l6, thereby rendering it possible for the operator at all times to view the article while it is resting upon the support 28 and also while falling through the passageway 2|.

Any number of these supports 29 may be pro vided and the supports may be arranged at any desired or suitable distance above each other to accommodate the various articles to be dispensed. The front edges of the supports 29 may be shaped to form projecting lips 23 (see particularly Figures 1 and 8) so as to permit the operator to view a considerable portion of the article or articles resting upon certain of the supports. These lips may be formed in any suitable manner.

Co-operating with each of the supports 29 is a guard or stop 25 constituting a holder for the articles resting upon the support. These holders or retaining means are preferably formed as a bale or of a substantially U-shaped configuration, the extremities of the sides of the bale being pivotally mounted as at 26 (see particularly Figure 19) in an upright 21 arranged at the respective ends of the supports.

These retaining members are mounted for free pivotal movement and connected to the extremity of one end of the retainer is a depending arm 28 (see particularly Figure 2).

The body portion of the retainer extends across the front edge of the support 29 and may be of any desired or suitable configuration and connected thereto are inverted substantially V- shaped elements 29 secured by one end to the retainer 25, the portions 29 of the retainers 25 being arranged so that they will be disposed between the portions 29 of the next adjacent retainer 25.

These retainers or holders 25, when in the position shown in Figure2, co-operate with the support 29 to hold an article thereupon and in position to be viewed through the transparent portion I8 of the front of the casing.

In order to release the article, the retainers 25 are moved upwardly by their pivots so as to permit the article to fall by gravity from the support.

This swinging movement is accomplished by means of a slide 30 (see particularly Figures 2 and 3) which is mounted upon a suitable portion of the machine for free sliding movement such as by means of a slot 3| through which pins or fastening elements 32 pass, and the slide is moved in one direction by means of a spring 33 one end of which is secured to an ear or projection 34 on the slide and the other end is anchored as at 35 to a fixed member 36 of the frame. The depending arm or extremity 28 projects into a slot or recess 31 on the slide and the slide is provided with an ,arm or upwardly projecting portion 38 through the medium of which latter the slide 38 is actuated against the stress of the spring 33 to raise the retaining means or holder 25 to permit the article to be delivered.

Any suitable mechanism may be provided for this purpose but a simple and efficient means embodies a member 39 (see particularly Figures 4 and 13) which is preferably provided with an opening 49 therethrough irregular'in cross-section. This member 39 is adapted to move upon a rod or member 4| also angular in cross-section and which fits within the opening 49 so as to cause the member 39 to rotate axially with the rod 4|. The rod 4| may be mounted in suitable bearings 42 secured to a suitable part of the frame of the machine.

Mounted upon the member 39 is a dog 43 movable about a pivot 44; and a spring 45 is provided one end of which is secured as at 46 to the dog 43 and the other end is anchored as at 4'! to the member 39. The spring 45 tends normally to hold the dog 43 against a stop 48 on the member 39.

The member 39 is movable longitudinally of the rod 4| so as to position the dog 43 adjacent a predetermined one of the slides 30 through the medium of which latter the retainers or holding members 25 are swung about their pivots against the stress of the spring 33.

When the member 39 is moved in one direction the dog 43 will contact the stop 48 and when the extremity of the dog 43 then engages the arm or projection 38 on the slide 30 one Wall of the slot 31 will contact the depending arm 28 of the retainer or holders 25 and swing the latter about its pivot to release the article on the support. When, however, the member 39 is moved in the opposite direction the back of the dog 43 engaging the arm 38 will be rocked about the pivot 44 against the stress of the spring 45 thereby allowing the dog 43 to pass back into a position that it may again be positioned against another arm 38 to actuate the retainer 25.

Any suitable means may be provided for moving the member 39 longitudinally of the rod 4|.

A simple and efficient means embodies a sprocket chain 49 (see particularly Figures 4 and 7) which passes over a pulley 59 adjacent one end of the rod 4| and also over a sprocket wheel 5| suitably located. Connected to one of the runs of the sprocket chain 49 is a member 52 to which latter the member 39 is connected, the member 39 being preferably disposed between suitable bearings 53 adapting the member 39 for movement with and with respect to the member 52.

When the member 52 is raised or lowered by operation of the sprocket chain 49 the member .39 will slide upon the rod 4| until the dog 43 is positioned adjacent the predetermined arm 38. The rod 4| is then rotated and with it the member 39 causing the dog to swing the retainer 25 about its pivot.

To the member 52 may be connected a pointer or indicator 54 (see particularly Figures 1 and 4) which latter is exposed from the front of the machine.

Indications 55 are provided at predetermined points and with which indications the pointer 54 is adapted to be brought into register to indicate the proper positioning of the actuating dog 43.

Any suitable means may be provided for operating the sprocket chain 49 such for instance as an operating handle 56 suitably located for free access from the front of the machine (see particularly Figure 1).

This operating handle 56 is connected to a shaft 51 to which the sprocket wheel 5| is secured and the shaft is journaled in suitable bearings.

An automatic locking means or arresting mech anism may be provided to arrest the shaft and to assist in holding the pointer and the associated parts in their adjusted positions. Such locking means may consist of a disc 58 having notches 59 in its periphery. A locking dog or roller 60 carried by a member 6| may be provided to enter the notches 59 and a spring 62 controls the operation of the locking dog.

Thus it will be seen that by rotating the handle 56 the pointer 54 may be moved to its desired position. After it has reached this position the rod 4| may be rotated and the selected retainer or holding means 25 will be operated to release the article. Any suitable means may be provided for rocking the rod 4| but preferably coin control mechanism may be employed, which is adapted upon the insertion of a coin, to permit the shaft to be rocked. Suffice it to say, that the coin control mechanism embodies an operating handle or knob 63 (see Figures 1 and 8) which, upon the insertion of a proper coin in the slot 64 will rotate a disc 65 (see particularly Figure 5). To this disc 65 is pivotally connected, as at 66, a link 61 the other end of which link maybe pivotally connected as at 63 to a bell crank lever 69 suitably supported. To the other end of the bell crank lever a link 10 is pivotally connected by one end as at H, and the other end of the link is pivotally connected as at 12 to an arm or projection 13 (see particularly Figure 4) which latter projects laterally from the shaft 4|.

Thus it will be seen that when the knob or handle 63 is rotated in one direction the upright shaft 4| will be rotatedin one direction through the medium of the intermediate connecting means and bell crank lever, and likewise when the handle or knob 63 is rotated in the opposite direction the shaft will be correspondingly rotated, so that upon operation of the knob 63 in one direction the operating dog 43 will swing the retainer 25 in one direction and when rotated in the opposite direction the dog 43 will pass the arm 38.

Carried by the shaft 51 (see particularly Figure 4) is another disc 14 which is provided with recesses 75 opening through its periphery and which recesses are preferably in alinement with the recesses 59. A slide 16 mounted to move upon a suitable guide i1 is provided with a slot 18 through which a fastening screw it passes. One end of the slide 15, which is preferably in the form of a bar is adapted to enter and fit within the recesses '55. The slide is given its movement by means of a bell crank lever 86 to which one end of the slide it is pivotally connected as at 8|. To the other end of the bell crank lever 86 a link 82 is pivotally connected, as at 83, and the other end of the link is pivotally connected as at 84 to the disc 65.

The link 82 is preferably provided with a notch 85 to receive the pivot 66 of the link 61 so as not to interfere with the operation of the mechanism.

This additional locking means is provided so that after the mechanism has been operated by the insertion of a coin, it will prevent unauthorized operation of the selecting mechanism and thereby prevent unauthorized removal of another commodity from the machine until after another coin has been inserted.

It will be manifest that inasmuch as the disc 65 is connected with the handle 63 of the coin control mechanism, when the latter is operated, the shaft 4! will be oscillated and therefore in order to prevent movement of the member 3a and indicator 54 longitudinally of the shaft 4| by the manipulation of the handle 56, after the coin control handle 63 is started to operate, this positive locking mechanism is provided as it will be manifest that if the member 39 and the indicator 54 are properly positioned with respect to the support from which it is desired to release or discharge the commodity, one of the recesses 15 in the disc 14 will be in alinement to receive the end of the slide 76 and therefore the coin control mechanism will be permitted to operate; but, should it so happen that the member 39 and the indicator 54 are not in the proper position so that one of the recesses 15 will receive the end of the slide 16, the end of the slide will engage the periphery of the disc 14 and it will therefore be impossible to operate either the coin control mechanism or oscillate the shaft 4!.

All of the above described mechanism, i. e. the member 39 and the indicator 54 are arranged on one side of the machine together with the slides 30, one slide being preferably arranged adjacent each of the supports 26 and individual to the retraining or holding members 25.

It is another purpose of the present invention to provide a means whereby a plurality of articles may be held upon each of the supports 26 yet separated from each other, to constitute a reserve supply so that when the foremost article, i. e. the one initially held by the retainer 25 has been dispensed, and after the retainer has moved into an operative position to hold another article, one of the articles on the support from which an article has been vended will be automatically positioned to be held by the retainer 25 so as to be vended upon the next operation of the particular retainer 25.

This is accomplished (reference being had more particularly to Figures 8, 9, 10, l1 and 12) by the provision of additional retainers or article holders 86, any number of which may be provided.

In the present exempliflcation of the invention these retainers are preferably in the form of gates or members which are connected to a bar 81 along one of their longitudinal edges and these bars are journaled in suitable bearings being preferably disposed in openings 83 in the support 20. A

These additional retainers 86 are spaced from each other for any desired or suitable distance in directions across the support and are adapted to be swung into position so as to stand uprightly with respect to the support as shown in Figure 8 and thereby retain or hold an article from advancing on the support, and to be turned downwardly so as to permit the article in the rear thereof to slide forwardly upon the support.

One end of the rod 81 projects beyond the end of the support 26 as shown more clearly in Figures 10 and 11, and is shaped to form an upright portion 88 and a downwardly curved arm portion 89. Slides 96-9l are arranged in alinement and with the proximate ends of adjacent sections in close relation to each other.

Inthe present eXemplifi-cation of this invention the structure will be described in connection with a mechanism in which the support 29 is divided into three sections for holding three articles.

The slides 9t-9l are provided with slots 22-93 through which fastening screws 54 pass for slidingly mounting them upon the fixed part of the machine. These slides 6E!9l are arranged in an inclined position, the angle of inclination being substantially the same as the angle of inclination of the supports 26.

A spring is anchored at one end. as at $6 and is connected at its other end as at 6? to the slide 96 and a similar spring 68 is anchored at one end, as at 99, and is connected at its other end, as at I86, to the slide 6!. These springs tend normally to move the slides in a forward direction and to a position that a shoulder ii)! on the slide 86 will be positioned under the extremity I62 of the arm 89 of the foremost or supplemental additional retainer 86 to hold the latter in an elevated position, while the spring 88 tends normally to move the slide 9i forwardly to position a shoulder I63 thereon beneath the extremity I64 of another of the arms 89, thereby locking its original retaining member 80 in an operative position.

The slide 90 is also provided with a laterally projecting portion I05 to form a shoulder or projection with which the shoulders or notches I00 on an arm I01 are adapted to engage to move the slide 90 backwardly by a stey by step movement against the stress of the spring 95.

When the slide 90 is at the limit of its forward movement and the slide 9I is also at the limit of its forward movement, the forward end of the slide 9I will be in close proximity to the adjacent end of the slide 90 so that at a predetermined time during the operation of the retainer 25 the slide 90 will operate upon the slide 9| to move the latter and thereby release the retainer 86 controlled thereby.

The arm I0! is pivotally connected as at I08 to the retainer 25 and a spring I09 tends normally to move the arm I0'I about its pivot I08 to position one of the notches or shoulders I06 to engage the projection I05.

The normal position of the retainers 85 and the slides 90-9l are as shown in Figure 12.

In this position an article will be retained by each of the retainers B6 and another article will be retained upon the support 20 by the retainer 25, as shown also by the lower unit in Figure 9.

It will be noted that the shoulder or projection I03 is of a width somewhat greater than the width of the shoulder or projection IQI. This is important in that it allows the slide 90 to be moved a sufficient distance that the extremity I02 of the arm 89 will disengage the shoulder IOI thereby allowing the retainer 00 to be swung downwardly by the article therebehind permitting this article to be moved forwardly to be retained upon the support 20 by the retainer 25.

When the end I02 of the arm 89 disengages the shoulder IOI it will assume the position shown in Figure 9 by the second unit from the bottom of the figure, the arm 89 then passing behind the shoulder to form a locking means for the slide 90 preventing it from being moved forwardly by the spring 95 during another step of operation of the arm I01. During these movements the extremity I04 of the arm 89 will still be retained upon the shoulder or projection I03 and the supplemental retainer controlled thereby be held in an upright position, as shown also in the second unit from the bottom of Figure 9.

As the retainer 25 is raised about its pivot by the slide 30 as heretofore described, the arm I01 will also be raised but the spring I09 will cause the arm I01 to move about its pivot to successively position the shoulder I06 behind the projection I05 during the successive operations of the retainer 25.

This will cause the slide to be moved backwardly by a ratchet or step by step movement to eventually cause the extremity of the arm 89 to drop off of the shoulder or projection I03. The shoulders or projections I03 are of a width to compensate the various movements of the arm I01 according to the position which these elements assume in the machine and also according to the space between the superposed supports 20.

Thus it will be seen that when the member 39 is positioned in the manner as already described adjacent the member 28 on one of the retainers 25, which has been predeterminedly selected, and the member 39 rotated, the dog 43 will engage the arm 38 to swing the retainer 25 upwardly about its pivot 26 to release the fore- 75 most article held by the retainer.

Upon the first movement of the retainer 25 the lowermost shoulder I06 will contact the edge of the projection I05 and the arms 89 will be in engagement with the projections IOI and I03 on the respective slides 90-9I. As soon as the retainer 25 is then released, the arm I01 will also be lowered but theshoulder I06 which is in engagement with the projection I05 will move the slide 90 backwardly against the stress of the spring a sufiicient distance to cause the extremity I02 of the arm 89 to drop off of the projection IOI, as shown in the second unit from the bottom of Figure 9. The article which was held by the retainer 86, the arm 89 of which engaged the projection IOI, will then be swung downwardly by the weight of the article therebehind and the article thus released will slide forwardly on the support 20 to be held and retained by the retainer 25 to be subsequently dispensed when the retainer 25 is again raised.

When this foremost articl is dispensed by the raising of the retainer 25, the same operation will be repeated and the second notch I06 will move into engagement with the projection I05 to move the slide 9| backwardly against the stress of its spring 98 to allow the extremity I04 of the arm 89 to pass off of the projection I03, thereby releasing the article held by the retainer 86 allowing it to slide forward by gravity unti1 it is retained by the retainer 25.

After the forward retainer 86 has been released and while the member I0'I is being moved upwardly to release the rear retainer, the slide 90 will be held locked against forward movement under the stress of the spring 95 by engagement with the arm 89 of the supplemental retainer engaging behind the edge of the projection IOI.

Obviously any desired number of these retainers may be provided according to the capacity of the machine and in order to add additional retainers 80, it is only necessary to add additional slides which operate successively. In such instances the only provision or change that ,would be necessary would be with regard to the width of the projections I III and I03 as they must be of sufiicient width so as to prevent the respective retainers controlled thereby from becoming unlocked until it is desired to dispense the article held by such retainer.

In Figure 9, the lowermost unit indicates the parts as they are in their normal or initial position. The unit B shows the position the parts will assume after the initial article has been dispensed and the foremost supplemental retainer 85 lowered to permit the article originally held thereby to be released and positioned to be retained by the retainer 25. The unit C shows the position the parts will assume when the rear retainer 8B is released so as to permit the article held thereby to move by gravity down the support 20 to be held by the retainer 25, while the unit D shows the parts in the same position as in the unit A, i. c. with the surface I06 of the arm I01 disposed behind the projection I05.

When the articles have all been dispensed from the supports or when it is desired to replenish the supply, after the retainers 86 have been lowered, it is necessary to reset them. This may be accomplished in any desired or suitable manner but preferably by means of a bar or slide IIO which is provided for the front side of the retainers 85 and a similar bar or slide III is provided for the rear side. Each of these bars is supported for sliding movement in any suitable manner and for that purpose they may be provided with slots II2 through which fastening screws or pins H3 pass and which screws or fastening devices engage a suitable part of the frame.

One end of the bar or slide H8 may be provided with a finger engaging portion or handle II4 by means of which the bar or red may be raised or lowered. Projecting from the bar are a series of lips or extensions II5 which extend under the arm I81 and also the arm 88, the latter being connected to the retainer 83 so that when the bar is raised the projection will first engage and raise the arm IiI'I about its pivot I88 and against the stress of the spring I39 and then will engage the arm 88 to rock the retainer 86 so as to elevate the extremity I02 of the arm 89 thereby permitting the spring 95 to move the slide 98 forwardly so that the projection or extension II]! will be moved into a position that it will be engaged by the extremity I82 of the arm 89 and the respective retainer will then be locked or maintained in its operative position to hold an article therebehind.

The bar I II is also provided with projections I I3 which operate upon the arms 88 of the rearmost retainer 86 in a similar manner.

Obviously in resetting the machine the foremost rod or bar I-II! must be operated first so as to permit the slides 99 to move forwardly a sufficient distance so as not to interfere with the forward movement of the rear slide 9I and the setting of the rearmost retainers 86.

The rear bar III may be shaped at one end to provide a finger engaging portion III and this rear bar is slidingly mounted by means of slots -II8 through which fastening or securing elements I I9 pass.

If desired and in order to limit the upward movement of the retainers 25, stops I20 may be provided for that purpose (see particularly Figure 9). The retainers 25 may be limited in their downward movement and held in their operating positions with respect to the support 20 by engagement with the ears or projections 23 at the for-ward edges of the supports.

In Figures 14 to 19 there is shown a modified form of the invention for locking the supplemental holders or retainers 85 in an operative position and for releasing the same so as to permit the article held in the rear thereof to be delivered toward the front of the support 28 to be held by the retainer 25.

In this form of the invention the slide I2I is held by fastening devices I22 passing through slots I23. V

The supplemental retainer 86 is provided with an are shaped arm I24 the extremity I25 of which is adapted to engage and rest upon a laterally projecting ear or extension I-26 on the slide IZI, when the slide is in the proper position, so as to lock the supplemental retainer 88 in an operative position.

The slide I2I is also provided with a laterally projecting flange I-Z'I provided with teeth I28 and a laterally projecting ear or extension I29 (see particularly Figure 16).

Pivotally mounted upon a fixed support and intermediate its ends as at I38 is a member I3I, having a bifurcation I32 opening through the end thereof. The other end I33 of the member I3I is provided with an edge I 34 adapted to successively engage the teeth I28 on the flange I2! of the slide I2I, as the member I3I is rocked about its pivot, and thereby impart an intermittent or step by step movement to the member I2I rearwardly until the ear or projection I26 has moved from beneath the extremity I25 of the arm I24 of the supplemental retainer 85, thereby unlocking the latter, allowing it to fall by gravity and by the weight of the article which is behind it, until the supplemental retainer 86 assumes a 'position to permit the article previously held thereby to slide downwardly upon the support 23 to be held by the retaining member 25. The retaining member 25 will reach its active position with respect to the support 20 just at the time that the ear or projection I26 on the slide I2I passes from beneath the extremity I25 of the arm I24.

If desired, the ear or projection I29 may be caused to serve as a means for limiting the forward movement of the slide IZI, as this car or projection I23 will contact the end I33 of the member I3I.

The member I3I is loosely mounted upon its pivot I38 and is adapted for a slight lateral movement with respect thereto, and this may be accomplished by providing an opening I35 (see particularly Figure 15) in the member, which is of a diameter slightly larger than the diameter of the supporting device or pin I30, and spring I3I which encompasses the element I30 and contacts the element I34 to hold the latter in position.

When the slide I2I has reached the limit of its movement in a direction to release the supplemental retainer 86, and in order to reset thesupplemental retainer, there may be provided a bar or member I36 which is provided with slots I31 and is held in position by means of screws I38 passing through the slots, so as to permit of a longitudinal movement of the bar.

Adjacent one face of the bar I33 is a releasing device mounted upon a suitable support which preferably comprises a body portion I39 journaled in suitable bearings I40 mounted upon a suitable support I49A. One end of the body portion I39 is shaped to provide an arm I4I, the

extremity I42 of which projects into a slot or opening I43 in the bar or member I36, the opening I43 being of a length considerably greater than the diameter of the end I42 of the arm I4I so as to permit the end I42 to readily enter and pass out of such opening when the bar I36 is moved longitudinally, for a purpose to be described.

The other end I44 of the member I39 is disposed behind the end I33 of the member I3I, and is so shapedthat when the member I39 is turned in its bearings I 49, the end I44 will engage the portion I33 of the member I3I to rock the latter laterally upon its pivot I30 so as to move the edge I34 of the portion I33 out of engagement with the teeth I28 to release the slide I2I, so that the slide may be moved to its original or normal position, that. is, the position in which the ear will be moved so as to permit the extremity I25 of the arm I24 to engage and rest thereupon.

By the provision of the slot I43, upon the first movement of the bar I36 upwardly, the extremity I42 of the arm I4I will move out of the slot and the side of the bar I36 will engage the extremity I42 to hold the end I44 of the member I39 in a position to maintain the edge I34 of the member I3I out of engagement with the teeth I28 to allow the slide I2I to move forwardly, the enlarged hearing or opening I35 in the member I3I and the spring I3 I serving to permit such movement'of the member I3I.

Pivotally mounted upon a fixed support is a bell crank lever I45 one end I46 of which projects into a slot or bifurcation I41 in the slide I2I, and the other end or arm I48 of the bell crank lever I45 projects into the path of movement of an arm or extension I49 on the bar or member I36, so that when the slide I2I has reached the limit of its movement in a direction to release the supplemental retainer 86, the arm or projection I49 will engage the arm I48 of the bell crank lever I45 to rock it about its pivot I59, thereby causing the arm I46 which projects into the bifurcation I41 of the slide I2I to move the slide forwardly so that the ear or projection I26 thereon will be in a position that the extremity I25 on the arm I24 will engage and rest thereupon.

This arm or projection I49 is of a sufficient length that before it contacts the arm I48 of the lever I45 it will engage a .portion of the arm I24 to rock the latter about its pivot to reset the supplemental retainer 86 and move the extremity I25 of the arm I24 to a position so that when the bar or member I36 is returned the end I25 of the arm I24 will engage and rest upon the ear I26. 7,

During the time that the slide I2I is in an active position, the arm I48 of the lever I45 will be elevated by the slide but will be moved downwardly or into a position to be engaged by the arm or projection I49, when the latter is moved to reset the mechanism.

With this construction it will be manifest that the slide I2I is positively moved into an active position at the same time that the supplemental retainer 86 is moved into an active position.

The member I3I is swung about its pivot I30 through the action or movement of the retainer 25 about its pivot and to that end there is provided a laterally projecting pin or lug I5I which projects into the bifurcation I32 of this member.

It is to be understood that with the present forms of the invention any number of supplemental retainers 86 may be employed or provided so that an additional supply of articles may be held in reserve upon each of the supports 20, and this may be accomplished by duplicating the slide mechanism I2I andthe locking means co-operating therewith.

In the operation of the machine after a coin is inserted into thecoin slot the retainer 29 Will be held open or raised until the selective handle 56 is operated to indicate a difierent selection. That is, the dog 43 will slide either up or down on the arm 38land when it clears this arm, the slide 30 is then returned to its original position, this in turn will lower or close the retainer 29.

While the preferred forms of the invention have 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 arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.
