United States Patent DISPENSING MECHANISM Wayne E. Sloyer and Arthur W.A Sloyer, Jr.,

Oakland, Calif.

Application August 21, 1953, Serial No. 375,7 y19 3 Claims. (Cl. 221-133) The present invention relates to improved dispensing mechanism and particularly to the type adapted toindividf ually dispense selected objects such as bottles of soft drinks in response to coin operated actuating means.

There have been developed numerous machines adaptedV to dispense individual objects from a plurality of like or dissimilar objects upon the insertion of one or more coins and designed to facilitate and further the sale of items without the necessity ot' attendant sales personnel. Particularly in the sale of confections and soft drinks have these devices found favor and increasingly complex are the dispensing mechanisms becoming available, however, this very complexity has proven disadvantageous in that mutilplication of the number of moving parts increases the probability of mechanical failure and the frequency of necessary inspection and maintenance to defeat the very purpose of automatic sales machines of this type. The present invention provides an improved dispensing mechanism having the very minimum of operating or moving parts and yet at the same time being substantially foolproof and quite convenient to operate. While the improved dispensing mechanism of the present invention may be employed to dispense any of a large variety of objects, the mechanism is for convenience herein disclosed and described in connection with the dispensing of bottles as may contain soft drinks or the like. In this respect note that the structure identified contemplates the handling of bottles having a top or neck with a lesser cross section than the lower bottle portion, however, such is not necessary for the objects to be dispensed may be substantially entirely enclosed, with fingers or the like extending into contact therewith from a position accessible to the user so that the objects to be dispensed are restrained from removal by other than the dispensing mechanism.

lt is an object of the present invention to provide an improved dispensing mechanism.

It is another object of the present invention to provide an improved dispensing mechanism for dispensing individual objects and having a minimum of moving parts.

It is a further object of the present invention to provide an improved dispensing mechanism including a pivotable carrier positively dispensing individual objects.

It is yet another object of the present invention to provide an improved dispensing mechanism having an entirely unrestricted dispensing aperture and means moving individual objects into alignment therewith for convenient removal therethrough.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention-as set forth in the clairns A preferred embodiment of the invention is illustrated: ai in the accompanying drawing wherein: t `v Figure 1 is a sectional plan view of enclosureand dis-Y pensing means embodying the present invention.

t Considering now the structural details of the illustrated embodiment of the invention, and referring: to the drawings, there is provided enclosure means 11 dei'ningfaf rectangular box having a hinged top `and preferablyVi yiii-1 cluding doublewallshaving insulation therebetweemas.

shown, to preservea reduced temperaturetherein., The t enclosure 11 is adapted to contain a plurality of containersv or bottles 12 placedupright uponthe bottom thereof and a horizontal top grill 13 is affixed within' the enclosure "walls with a plurality of longitudinal slotsorjguideways 14 therein through which the tops of lfthe bottles are adapted to extend. The guideways havea width greater ing of the enclosure means 11 may be'a'ccoinpli'shed through a door .16 provided in the side wall thereof /andf communicating with each of the guideways, locking` means, not shown, are preferably provided on the side,-

door 16.

The parallel guideways 14 in the horizontal grill 13* each communicate with a transverse slot 17 .of the same width as the guideways and extending'across the er1- closure means 11. A vertical side wallv 18 extends along and downwardly from the transverse slot `17 defining one side thereof and a horizontal top wall 19' is/secured to side wall 18 at the top thereof and extends therefrom 1 away from the transverse slot in the grill 13. Removal of bottles from the enclosure means 11 for dispensing is accomplished through an opening 21 provided in the side wall 18 and having a width at least equal to the maximum bottle width so that the bottles readily pass therethrougl The top wall19 is also provided with 'an aperture therein including a 'slot 22 extending away from side wall 18 andv thence at right angles parallel to the side wall 18to an enlarged access aperture v23 larger than the bottle cross section so that the bottles may be readily withdrawn therefrom; insofar as the above noted walls are concerned the bottles are thus movable longitudinally of thef guideways 14 into the transverse slot 17 and thencei through the side wall opening "21p, the Ybottle top beingI then movable through the top wall slot 22 into the access aperture 231 i Considering now the dispensing mechanism itself, there is'provided a housingZftl including the top Wall 19 and the side wall 18 or a counterpart thereof together with a pair of end Walls 26 and 27 and another side wall-28 defining a rectangular chamber I29. Within the chamber 29 there is provided a carrier 31 having a bottom platform 32 and side walls deiining abottle receptacle into which individual bottles 12 are adapted to slide through the side wall openingf21. A shaft 33 is mounted within the dispensing chamber 29 between the side wall`s18- and 28 thereof perpendicularly to same and directly below the opening'zl in the sidewall 18. One or more flanges 34 depend from the carrier platform 32 and the vshaft 33 extends therethrough in `rotatable relation thereto so that the carrier 31' is pivotable about the shaft 33. The carrier- 31 at least includes a front-wall 36 extending up-` wardifrom the" platform edgenearest the access aperture the side adjacent side wall 18, other carrier walls being optional.v `In `vertical or normal position the carrier 31 is disposed in communication'with the interior of the en.

:'23 in the-top wall and is at least open at the top and onf closure means 11 through the opening 21 in the side wall" 18 so that a bottle may be readily slid onto the carrier platform 32 from the' enclosure means 11. A bottle'upon the platform 32 of carrier 31, as shown in Figure` 2,

extends through the slot 22 in the top wall but is noty 11e-J movable therethrough because ofthe-small slot Width and is not'rernovable through the access aperture 23 in the top wall 19 because the carrier front wall 36 intervenes.

`.With regard to the pivotingof the carrier 31 there is provided vnieans to-controi same and adapted to operate i .a pin 41 attached to the carrier 31 as at the back wall thereof and extending through an opening in the wall ZS'perpendicularly to the crank and through a longitudinal slot in the end thereof. In the normal upright position of the carrier 31 the crank arm 39 is slanted away fromthe"ac`cessV aperture 23 and is locked in such position by the coin device 37 to hold the carrier 31 from movement. Operation of the coin device 37 by insertion of a coin frees the shaft 38 so that the crank arm is free to rotate or pivot about the shaft axis and tilting of the carrier is thus possible with the carrier' pin 41 sliding in the slot .in the crank arnr as same pivots. By4 limiting the length of the slot in the crank arm 39 the pivotal travel of the carrier is likewise limited as the carrier pin 41 cannot move further than the slot length. There is additionally provided as a part of the dispensing mechanism closure means 42 upon the carrier 31 extending parallel to the side Wall 18 adjacent theretoiand disposed, in the normal position of the carrier, beside the side wall opening 1S away from the top wall access aperture 23.

Considering now the operation of the dispensing mechalnisrn it is first noted that in the rst or normal position of the carrier 31, same4 communicates with the interior of the enclosure means 11 through the opening 21' in the side wall 18 so that a bottle may be slid along any one of the guideways 14 and transverse slot 17 onto the carrier platform 32 with the bottle top then extending upward through the top wail slot 22. In this position the bottle cannot be removed for the front carrier wall`36 isdisposed between the top wall access aperture 23 and Vthe bottle 12.k Actuation of the coin devicer37 frees the shaft 38 so that the userupon -graspingthe bottle top may readily pivot the carrier 31 about the shaft 33 carrying same with the pin 41 rotating the crank arm 39 and sliding in the slot therein until the pin reaches the end of the slot, in which position the bottle 12 is aligned with the top wall access aperture 23 so that it may be readily withdrawn from the carrier 31 through this aperture. As the shaft 38 is freed by the coin actuated device 37 a force applied to the left upon the carrier as shown in Figure 2, as yby one urging the bottle 12 in that direction, causes the carrier pin 41 to rotate the shaft 33 and arm 39 so that the carrier and arm move into the position shown in dotted lines in Figure 2. Movement of' the carrier 31 also moves the extension 42 theren of which thereby pivots across the side wall opening 21 function of .blocking `the side wall opening 21 when the.

Y actuated devices to prevent a second pivoting of the carrier 31 without insertion of acoin in the device 37. In this iirst position the carrier is again receptive of a bottle of tl e users lchoosing'from the enclosure means 11 and the above operation is then repeatable.

It will be Yappreciated that the carrier is at all times A' receptive of a single bottle from therenclosure means 11 fio except when pivoted to the second position and that in this latter position no way of removing other than the single bottle on the carrier is possible. Also the access aperture through which the bottles are singly removed is at all times completely open so that the chosen bottle may be most conveniently removed therefrom. Provision may be made for limiting the backward pivoting of the carrier 31 as by contacting the dispensing chamber end wall 27 with the carrier extension 42 in the normal carrier position and also means such as a llight spring or a counterweight may be employed to normally position the carrier in upright unpivoted position. Similarly the lower portion of the carrier may be made solid to increase the weight thereof and stabilize the unpivoted position thereof, as shown in Figure 3.

It will of course be appreciated that the dispensing mechanism need not be formed integral with the enclosure means as illustrated for although they may, as shown, form a single combined device including bottle storage space or the like, the dispensing mechanism may be separately constructed and thereby adaptable for cooperation with any enclosure means either of the type illustrated or of other types.
