(Cl. B12- 36) 16 Claims.

This invention relates to improvements in dispensing apparatus and has as one of its principal objects the provision of dispensing mechanism including a rotating drum with vertically extending article compartments around its periphery and pivoted carriages underlying each compartment to support the bottommost article of a stack as the carriage rides around a track responsive to rotation of the drum, the track having an interrupted portion constituting a discharge station which permits a carriage to drop and discharge the bottommost article resting thereon.

Another object is the provision of means for sustaining the remaining articles in a compartment of the drum in the region of the discharge station when the lowermost article is discharged by dropping of the carriage.

A further object is the provision in dispensing apparatus of the type characterized, of means for lowering articles from a higher level t a lower level onto empty carriages.

Still another object is the arrangement of a carriage track so formed that a pivoted or dropped carriage will be restored to a normal article-supporting position when the carriage is moved past the discharge station by subsequent rotation of the magazine drum.

Still other objects reside in details ci construction of the movable bottom or carriage members, with particular reference to the roller means thereon, means providing a resilient seat for the articles, and means disposed beneath said articles to facilitate sliding movement of the article from the dolly or carriage when the same is tripped or lowered in dispensing operation.

Still other objects reside in specific features oi construction of the track means upon which the dollies or carriages ride, and the formation of the track by means of which the carriages are restored from a tripped or dropped position to a normal article-sustaining position.

Still further objects reside in speciiic details of construction and operation of the article-sustaining and lowering means, whereby articles above a certain level in the drum are temporarily sustained against descending movement during their transit past a discharge station, such articles thereafter being guided in sequence to a lower level.

Other novel aspects of the invention reside in certain details of construction, operation and arrangement oi the preferred embodiment hereinafter to be described in view of the drawing, in which:

Fig. 1 is a fragmentary vertical section through a dispensing machine showing the lower part of a magazine drum incorporating features of the invention;

Fig. 2 is a fragmentary horizontal section through the drum and the peripheral drive means therefor;

The present application constitutes a continuation in part of my copending United States application, Serial No. 198,155 (see also application, Serial No. 198,157) (issued October 22, 1940, as Patent No. 2,219,206), wherein there is described a dispensing apparatus including certain features of construction disclosed herein.

The present invention is illustrated herein as a part of a coin-controlled dispensing apparatus adapted to dispense packaged items of various kinds including food stuffs, ice cream, and bottled goods including beverages, milk, and the like.

The dispensing apparatus includes a cabinet l2 having a door I3 constituting a ycontrol panel, upon which is mounted a discharge tray or basket irl provided with a resilient article stop I5 at its outer end and communicating at its inner end through normally closed yieldable gate means I6 with a discharge chute Il having its inner end or mouth I8 positioned opposite the article dispensing or discharge station of a drum type magazine dispensing mechanism (Fig. 3 also).

A magazine drum suitable for use with the present invention includes a plurality of vertically extended partition members 2t clamped between opposite axial end castings 25 constituting the bottoms of a skeletonized drum with the partitions 24 arranged about the periphery of the drum and mutually serving to provide adjacent vertical article compartments 2t in which articles such as bottled beverages 27a-2lb are stacked one upon another. In the drawing, only the bottom casting 25 is shown, a similar casting being provided at the upper end of the drum, and both castings having some form of bearing means such as the roller bearing 28 (Fig. 1) supporting the drum for free rotation about a vertically extended shaft 29 having a lower end portion secured in a stanchion 30 on the bottom of the cabinet l2 at a distance sufficiently below the bottom drum casting to provide a precooling storage compartment opposite the lower axial end of the drum.

The casting at the upper axial end of the drum is particularly shaped to provide a maximum clearance between this end of the drum and the upper portion of the cabinet to accommodate certain cooling' mechanism (not shown) in the manner set forth in the aforesaid copending application to which reference is invited for further details of construction of the skeletonized drum and the novel mounting means therefor.

It is to be understood, however, that any type f vertical rotatable drum may be employed with the present invention so long as such drum has vertically extensive article compartments open at their bottoms, the invention being particularly concerned with the provision of meansfor temporarily closing the said open bottoms, in a manner of speaking, to support a stack of articles in fthe corresponding compaitmei'it, the means being movable to withdraw support so that the bottom-most article can gravitate from the compartment, the invention further providing, as heretofore panticularized, means for temporarily sustaining the remaining articles in a compartment 4vvhen lthe bottoml is opened or the bottom support temporarily withdrawn.

The several vertical article compartments 25 of fthe drum each have open bottom portions 26 (Fig. 3, lower right), and beneath each of these open bottoms there is arranged a movable closing means in the form of a traveling bottom member or carriage 35. These traveling bottom members are variously referred to herein as carriages or dollies, and each of the same is preferably constructed in the nature of a casting having a platform portion 35 (Figs. 4 and also) having a pair of depending spaced legs 31 and 3S between which is mounted a roller 39 on pin meanslli seated in the legs. Extending laterally from the leg members 3l and 35 and connected therewith by` reinforcing ribbing Iii, is a horizontal arm, @2 having a lateral b-ore i3 yat 'its free end and through which there is eX- tendecl a pivotal-mounting pin means @il seated Y, i;

in the spaced arms i5 of a bracket 46 secured by means lil to the under side of the bottom drum casting 25 in positions beneath each of the vertical magazine compartments.

The dollies or carriages 35 are thus mounted for pivotal movement into and out of raised position `beneath the open bottom portions of corresponding magazine compartments 26, and in their raised positions their respective platform portions 36 are disposed in a substantially horizontal plane so as to support articles in the compartments, provided there is some form of y support beneath the several dollies. The invention provides a novel supporting track means to be described hereinafter.

Itis contemplated that articles in the several magazine compartments will be lowered from higher levels into the corresponding dollies or carriages, and in orderY to provide a yieldable landing surface on the several carriages to break any shock sustained by the articles, there are provided caps `(Fig. 5) of resilient material, such as rubber or the like, the cap in the present embodiment being of cup-like. form with an inner flange 5I adapted to underlie the under side of theplatform 3S of the carriage to hold the cap in place.

In order to expedite the dispensing action of the carriages when the same are released from article-supporting position, as will be described hereinafter, each of the resilient cap members 59 is provided with a gliding strap 54 in the nature of an elongated strip of metal having its opposite end portions turned back to provide clamping formations 55 turned around the bottom rim or periphery of the corresponding cap beneath the carri-age platform, 36. An important feature of the gliding strap arrangement is the provision of a diametric groove or cut 56 across the top of each cap and into which the corresponding gliding strap is closely tted, the portions of the groove or cut toward the center of the 'cap being slightly deeper so that the strap may be sunk or depressed a very slight amount beneath the surface level of the resilieirt cap in its central region, the purpose of this arrangement being to assure a maximum resilient landing surface exposed to the bottom of a descending article as it lands on the cap. It is also important to observe that in vthe dispensing operation of the carriages, that is, when they drop, the article supported thereon will be tilted by means Ihereinafter to be described so as to rock such article onto, a bottom edge portion thereof, such edge portion riding on the strap llwith the least amount of friction. By this means, the `discharge of the article starts at once upon release of'rthe carriage, and the discharging movement is rapid and positive due `to the gliding surface especially provided by the strap 54.`

Means for supporting the several carriages in normally raised article-supporting position includes a substantially annular track 6l) forming the rim of a casting including spoked member 6l radiating from a hub 52 which embraces the verticalshaft 29 immediately below the bottom axial end plate or casting 2-5 of the magazine drum, the hub portion S2 being held immovable on the shaft 29 by a transverse stay pin 63 extended therethrough.

The track Eil is dimensioned to underlier the roller portions 39 of each of the carriages in their cycle of movement with -the rotatable drum; or magazine structure so that the carriages are supportedV in upright or horizontal position beneath their corresponding compartments, closing the open bottom portions 26 of such compartments and thus constituting a releasable or 4movable bottom support for the several compartments.

Means for effecting release of each of the movable bottom portions or carriages 35 in sequential order as the magazine drum rotates in a given direction, includesthe formation oi an interruption atthepointli (Fig. 3) of the track Sli so as to remove support frombeneath the carriages movingover that point. `The interrupted section of the track ispositioned substantially opposite themouth I3 of the discharge chulte l1 so that as the dispensingdrum is rotated in steps in a particular direction (toward the left in Fig. 3), the dolliesor carriages Will drop one by one and eifect'gravitating movement of any article thereon into the chute IlV for discharge through the gate l@ onto the tray struc-ture I4. It may be pointed out here :that the invention further provides means for temporarily sustaining -articles in the Several compartments resting upon a lowermost article which is discharged by dropping of the movable bottom or carriage member until Vsuch articles have passed the dispensing station.

Means for automatically restoring the several dolliesto normal article-supporting position includes the provision in the track structure 60,

and particularly in the interrupted portion thereof, of a translatory track section having one endwise section 65 tilted in a vertical sense in the region near the end point 64 of the main track, this offset section 65 being so disposed (Figs. 1 and 3) that as each dolly drops olf the end point B of the main track, the roller portion 39 thereof will bear against the upright or tilted track section 6'5; and as the drum continues its unidirectional movement, the dolly will be gradually pivoted back into normal horizontal position as a result of the translatory curvature of the restoring track section by means of which the substantially upright or vertically tilted restoring section G5 gradually curves back in the region B6 into a horizontal plane substantially at the point indicated at 6l.

In order to sustain the articles at higher levels in each of the compartments as the several compartments pass before the dispensing station, there is provided an article-sustaining means comprising a bracket structure lil in the form of a cast ribbed plate supported in a vertical plane behind the door i3. This plate, it may be observed, also constitutes a mounting for a coincontrolled mechanism not shown herein but described in greater detail in the aforementioned copending application. In the present case, the bracket plate 'f may be of any desired form and supported by any suitable means, and in the present embodiment the article-sustaining means is desirably formed as a part of this bracket plate and includes a horizontally extending elongated ledge formation H having a receiving edge portion 'l2 disposed substantially above the track interruption Ell, the opposite or discharge end 'l of the sustaining ledge terminating at a point substantially above the restoring point 6l on the translatory track.

The sustaining ledge 'H is disposed at a height 21B long enough to assure that the advancing bottom edge of the upper bottle will ride onto the horizontal edge of the sustaining ledge, this provision being the result of the particular location of the track interruption 64 with respect to the receiving or leading edge 'l2 of the sustaining l ledge.

In the present dispensing apparatus, the inner vertical surface portions of the sustaining ledge adjoining the receiving end 'l2 are suitably chamfered to provide a gliding surface 14 (Fig. 1) so positioned with respect to the upper portions of the bottommost article or bottle 21B as to tilt the latter inwardly toward the drum as the latter completes movement of the article to be dispensed toward the dispensing station in such manner that as soon as the corresponding dolly drops, the article to be dispensed will already be in an inclined attitude preparatory to gliding downwardly along the gliding strap 54 and into the chute il.

Similarly, the inner edge portion (Fig, 3) of the sustaining ledge adjoining the top gliding surface and the inner vertical surface is chamfered to assure smooth gliding action between the same and the bottom of the advancing article.

Means for automatically effecting a lowering yof articles from the higher level on the sustaining means to a lower level, and onto a restored dolly or carriage, includes a restoring ramp pivotally attached as at 8| to a projection at the end 73 of the sustaining ledge or bracket. This ramp is so curved and disposed as to have its lower terminus 82 positioned substantially above a fully restored carriage or dolly advancing from the translatory track section S7 so that when the drum is subsequently advanced after each dispensing operation, the temporarily sustained bottles are advanced step by step toward the ramp 3S, such bottles gravitating down the ramp and onto the restored dollies therebelow. Further guiding the automatic lowering of the bottles from the sustaining ledge is a iin 83 pivotally mounted on vertical pin means extended into the lower inner side of the ramp 80 as at 84, there being a coil spring 85 embracing the pin means and bearing against the iin to urge the latter toward the drum, the fin being so curved and disposed as to engage the outer edge portions of a descending article and guide such article into centrally seated position on the restored dolly.

Any suitable means may be provided for advancing or rotating the magazine drum, and for purposes of illustration I have shown to reduced scale in Fig. 2 a fragment in horizontal section through the drum to illustrate one form of drum moving means, which means includes a ring gear 9i! preferably formed in segments and extending around the drum in its upper region and secured to the outer portions of the several compartment partitions 24, preferably in the manner set forth in the above-mentioned copending application'.

The dispensing apparatus includes a coin-freed control (not shown herein) preferably mounted on the upwardly extending portion of the mounting bracket plate 'l0 referred to in conjunction with Fig. 3, said control including a driving pinion 9i meshing with the ring gear 90 on the drum and arranged for unidirectional step b-y step movement through the agency of a special coincoupled driving mechanismoperated by a control handle s2 which is moved through one complete oscillation to effect a partial advance of the pinion 9i with a corresponding movement of theV magazine drum a distance equivalent to that between any two adjoining magazine compartments.

A brief summary of the operation of the device setl forth herein includes the manipulation of the control handle 92, in the manner set forth, and corresponding advance of the drum to move one of the dollies 35 over the track interruption 6A whereby support of the carriage or dolly is removed and the dolly will drop into lowered position opposite the discharge chute I'l, as seen in Figs. l and 3, any article such as a bottle on said carriage gravitating into the chute and onto the discharge tray I4.

Any article or bottle above the aforesaid discharged bottle, and supported thereby previous to the discharge, will have moved onto the temporary sustaining ledge 1I meanwhile, that is, just prior to the time the corresponding dolly approaches the end 64 of the track 60. Subsequent advancing movement of the drum will move the temporarily sustained articles along the ledge H toward the ramp 8l), and at the same time the lowered dollies will ride over the translatory track section 65-66-81. and thus be automatically restored to horizontal or article sustaining position, so that when such restored dollies approach the lower end 82 of the ramp 8l), they are in position to receive an article or bottle gravitating down the ramp as a result of continued advancing movement of the drum. I n this way, the lowermost articles in each compartment are disposed in sequential order, the articles at the next higher levels being lowered automatically one by one into lower levels.

Itis to be understood that the invention is not restricted to any precise form of dispensing drum such as Athat described in detail herein, nor is its application limited to any particular form of vdispensing mechanism so far as the housing, control means and nature of the articles dispensed is concerned, the invention in its broader aspects relating more particularly to the provision of a movable article magazine with serially arranged article compartments each having movable bottom sections and means sustaining the bottom sections during a major part of the movement of the magazine, together with means for effecting removal of the bottom sections one by one to permit discharge of an article thereon as such bottom sections approach apredetermined position. v'Ihe invention further contemplates means for temporarily sustaining the remaining articles in the magazine compartments as the same move past said predetermined position.

The invention is, therefore, not limited to the precise form of construction, arrangement, or operation set forth herein for illustrative purposes, but embraces all equivalent constructions, arrangements and modes of operation fairly coming within the call of the appended claims.
