This invention'relates to 4apparatus for dispensing bottles,cans, or `the like, .particularly round vbeverage bottles or cans. It is one'of the objects ofthe present invention `to provide `a bottle dispensing apparatus which may be placed into a box or cabinet, suchA as av refrigerator, and which will dispense the bottles safely and `with out any reasonable likelihoodof breakage. rIt is a further object of the presentl invention to provide such .1an4 apparatusiwherein the'bottle being dispensed, aswell as the remaining bottles in the apparatus, will be subjectto. substantially no `jarring. Y This is of importance in dealing with carbonated beverages.

It is a still further object of the present invention to provide a `dispensing Aapparatus of the above 'mentioned `character which is simple of 4construction and has a minimum number of movable parts. t i l y i Another object of the present invention is the provision of a dispensing unit .Whicncan easily and simplybe changedto accommodate different sizes of bottles, from lvery smallbottles to comparatively large bottles, without involvingexpensive, complicated or difficult operations to vmake adjustments.. i Still another'. object of the `present invention is theprovision of a manually operated dispensing junit which will .always dispense one, and only one bottle veach time it is operated While there are;bottles in the unit.

In accordance with .the preferred embodiment ofthe present invention the bottles are stacked one above another in a vertical row,y each bottle resting onfand being supported by the bottle below it. The lowermost bottle `is supported by a shuttle mechanism .which is vertically movable and preferably arranged to` support also the second lowermost, bottle. Upon movement ofthe shuttle in one direction the lowermostV bottle is discharged while the .next lowermost kbottle is supported and gently lowered tothe positionnecupied bythepreviouslylowermost bottle. All of the remaining bottlesy in the row then move gently downward an amount equal tothe diameter of the. bottle discharged In the preferred construction the bottleto be discharged is held in `the shuttle mechanism,andspreferably out of contact with the remaining bottles of Ithe row.

Upon downward movement of the dispensing unit or ,shuttle mechanism, the botuein the Shuttle 'l mechanism is .discharged and the lowermost bottle of the row is permitted to move by gravity to aposition `where it is ready to enterthe shuttle mechanism upon subsequent return of theshuttle mechanism to its normal position. As the shuttle mechanism` is lowered by manual operation of the dispensing unit the bottle gradually rolls towards a discharge chute. When the shuttle mechanism approximatelyr reaches its lowermost position there is justenough clearance for the bottle to roll from `the shuttle mechan Anisrnyto the discharge chute. This avoids any substantial agitation of the contents of the bottle. vThe attainment of the. above and further ob- .jects of the present invention will be apparent from the following specification taken'in conjunction with `the accompanying drawing forming a Dart thereof.

Inthe drawing: Figure -1 is a front view of a coin controlled refrigerator in which the` dispensing unit of the 'presentinvention may be mounted; l

Figure `2 is an enlarged fragmentary'sectional l view;V through one of the, dispensing units ofy the present invention;

Figure y3 is a View, similar to Figure 2 and showing `the dispensing unit in 1an alternate position; and

- Figure 4 is a fragmentarysectional viewv taken f 'along `thefline 4;-4 of .Figure 2 and looking in Vthe direction of the arrows.

- Reference may now` be had more'particularly Vto Figure l. A refrigerator, indicated at I, isof the electric or. other well known type and may contain the'usual electricmotor driven compres'- sor at the lower partthereof, and contains the `usual cooling coils whichmay be located at the back of the box `or at the top of the box, asis desired. The refrigerator is provided with the .usual hinged door 3 for permitting access theref into and va latch 4 for'holding the door closed.

:The latch is locked vand controlled by a key lock 5 to prevent unauthorized opening oftheY door.

A number of delivery chutes, closed by hinged doors 8, 9 andl 10, open at the lower part of the refrigerator. vEach of the doors is pivoted at l2 and normally extends downwardly and is held there by gravity or by a light spring to maintain the cutlet'of4 the delivery chute closed against the escape of 'cold air from the refrigerator, The front of. the refrigerator also has a coin con'- vtrolled mechanism` I4 having a `push button l5 for returning a coin before thecoinhas been collected, as may be :necessary in the event that the selected merchandise compartment is empty.

`The handles of a `number of levers i6 extend .forward of the, refrigerator-through narrow slots l'l The handles of thelevers are manually mov- `rable under the control of the coin box mechanism i4 and are interlocked so that only one handle may be moved at a time in response to the deposit of a coin in the coin box mechanism. Below each handle may be placed a label for indieating the beverage in the compartment or section controlled by that particular handle. Thus bottles of various different types of beverages may be placed in the different compartments of the dispensing unit, to be hereafter described, which compartments are controlled by the different levers I6 so that a customer may select a beverage by selecting and operating the corresponding lever I6.

To receive merchandise the customer deposits a coin into the slot of the coin box I4 and thereafter depresses any one of the selected levers I6. If the compartment containing merchandise controlled by thev particular selected lever is empty then the lever is automatically locked against operation. The customer may then choose to operate a different lever or may press the button I5 for the return of the coin. The particular means for locking the lever against operation when the compartment containing merchandise controlled thereby is empty forms no part of the present invention, hence no description thereof is here necessary. For a description of one suitable operation locking mechanism reference may be had to the pending application of AMilton L. Smith and Robertv Schwalb, Serial No. 424,466.

The dispensing unit of the present invention is placed in the refrigerator in much the same manner as is the dispensing unit of the refrigerator of the application of Milton L. Smith and Robert Schwalb above referred to. The dispensing unit comprises a plurality of similar sections of which one is shown at in Figure 2, a similar section to the left of it is indicated at 2I and a third similar section tothe right of it is indicated at 22.` Each section, such as the section 20, includes a bottle stacking compartment 23 in which the bottles to be dispensed are placed one above the other, each bottle res-ting on the preceding bottle for subsequent delivery from the unit, and a precooling compartment 24 to hold bottles for precooling to be subsequently placed into the bottle stacking compartment. A stationary plate or wall 25 separates the sections 20 and 2l, and a similar stationary plate 26 separates the sections 20 and 22. A stationary plate 21 divides the section 20 into the two compartments 23 and 24. The plates 25, 26 and 21 lie in ver-tical planes extending from adjacent the front of the refrigerator to adjacent the rear of the refrigerator. The space between the plates 26-21 is provided with a plurality of horizontal shelves such as the shelf y28, extending between the plates and spaced apart vertically an amount slightly in excess of the height of the bottles 29 to be placed on each shelf. Since each bottle is about three times as tall as its diameter and the shelf is equal to the length of a bottle approximately three bottles can be placed on each horizontal shelf 28, one in front of another. If the dispensing unit is of a height to receive approximately seventeen bottles in each dispensing or bottle stacking compartment 23, then there will be approximately ve shelves 28, one above the other, each shelf receiving approximately three bottles. Thus each section will hold almost as many bottles in the precooling compartment as in its dispensing compartment.

A bottle guide 30 is removably secured to the plate 25 adjacent the bottom thereof in any desired manner, as by bolts or screws. The bottle guide includes a projection ledge 3I which projects twards the plate 21 and preferably extends the full width of the plate 25 from the front towards the rear of the refrigerator and includes an upper tapered portion 32 and a lower circular or cylindrical guiding portion 33 terminating at an edge 34.

A shuttle. mechanism 36 is mounted-for vertical movement adjacent .the bottom of the section 20, This mechanism includes a vertical plate or bracket 31 carrying an upper bottle stop 38 and a lower bottle stop`39, a horizontal plate 40 integral with the plate 31, a second vertical plate 4I .integral with the plate 40, an inclined guide plate 42, and a vertical guide plate 43 all constituting one integral structure. The plates 40, 4I and 42 thus constitute a trough .for receiving bottles, one at a time, from the stacking compartment. The stops 38-39 constiltute projections from the surface of the plate 31 in a direction towards the adjacent plate 25, and the plate 42 constitutes a projection from the surface of the plate 43 in a direction away from the adjacent plate 25. The shuttle is movable downwardly from the position illustrated in Figure 2 to that lillustrated in Figure 3, in a manner to be more fully set forth as this description proceeds, for discharging a bottle from the trough of the shuttle to a discharge chute 55. Metal guide straps or bars 44 and 45 are an integral part of the shuttle and fit snugly through slots in a bottom stationary plate 46 for guiding the shuttle in its up and down movement. The shuttle has a strap 48 secured thereto and depending therefrom, which strap is adapted to be secured to the operating lever I6 as by a pin 49. The operating lever is pivoted to a stationary part of the refrigerator or 0f the dispensing unit, as indicated by a pin 50. Compression springs 52 are provided for urging the shuttle mechanism to its uppermost position illustrated in Figure 2. When the shuttle mechanism is lowered, as by manual operation thereof in a .manner to be presently more fully set forth, the springs are compressed so that upon release of the force tending to lower the shuttle mechanism it is returned to its position illustrated in Figure 2 by the compression of the springs.

The bottle stops 38 and 39 are in the form of bars extending horizontally transversely of the refrigerator, preferably for the full depth of a bottle in the compartment 20.

A chute 55, located below the bottle stacking compartment 23, receives the bottles from the shuttle mechanism 36 when the shuttle mechanism is in its lowermost position. At that time the lower edge of the ledge 42 is approximately 'at the level of the edge of the chute 55, as illustrated in Figure 3, so that a bottle can roll gently from the shuttle mechanism to the chute, along which it then slides downwardly t0 be discharged on the outside of the refrigerator.

The entire dispensing unit for the refrigerator cabinet here illustrated consists of six sections such as the section 20, a single chute 55 being provided for each two adjacent sections. As may be seen from Figures 2 and 3, adjacent sections are so located that the bottle dispensing compartments 23 of the sections 20 and 2| are adjacent one another whereas the bottle storage or precooling compartments 24 of the sections 20 and 22 are adjacent one another. Thus the shuttle mechanisms of .the sections 20 and 22 are adjacent one another. The movable part of each section, constituting the shuttle of the section, is thus adjacent the movable part of the adjacent section whereas the stationary part of each section, .which :is :the lside thereof vwhere the ledge 3i 'is mounted, :is adjacent the corresponding side of itsladjacent section. This is in the -same manner :as in l.the Smith iand Schwalb application above `referred to, to which further :reference may -be made. i i

The distance between the stationary ledge 3| and the movable bottle stops 33-39 is `of importance in determining the amount of agitation y The ledge .38 extended its inch from the wall 2l` whereas the ledge 39 yextended 1A inch .from `the wall 2?|. This was a :suitable arrangementfor bottles of .2% inches Ydia-meter. If this structure 'is to be used `with bottles of 'different diameters the stops 38-3S are replaced by larger 'or smaller stops as may be necessary, and the ledge `3| is also replaced by one that extends a greater or lesser distance from the wall 25.

.An explanation will now be given of the manner of operation of the mechanism of Figure 2. The bottles are placed in the machine, as indicated at 60, 6|, 62, etc., there Kbeing as many bottles above the bottle 62 as there'is room for in the bottle stacking compartment 23. A selected lever I6 is manually depressed. This Amay be done after a coin .has been deposited in the coin box or= if the apparatus is not to be coin controlled, then no interlock is provided between the levers I6 so that any lever may be operated `at any time. Downward movement of the lever i6 causes the strap '48 to pull the shuttle mechanism downwardly. This causes the bottle 60 to move downwardly, said bottle continuing to rest on the inclined guide plate 42 and the edge 34 of the guide portion 33. bottle v6| which rests between the upper left hand corner of the bottle stop 39 and a corner 65 of .the .ledge 3| moves downwardly. The clearance between the ledge 3| and the stop 39 is insuicient to permit the bottle 6| to move immediately into the guiding portion 33. As lthe downward movement of the shuttle continues the bottle 6| and all of the bottles above it move downwardly. This motion continues until thestop 39 reaches the position indicated in dotted lines in Figure l 3. In this position the distance .from the corner 66 of the stop 39 and the corner 61 of the .ledge 3| is just suflicient to permit the bottle 6| to roll into the lower circular guide portion 33. At this time the guide plate 42 of the shuttle is in the dotted line position illustrated in Figure 3 and the distance between the edge 68 of the shuttle and the edge 34 of the ledge 3| is also equal to the diameter of a bottle. Therefore the `bottle 60 rolls from the position illustrated in dotted lines in Figure 3 into the chute 55, as illustrated in full lines in Figure 3, from which it then slides down the chute through the trap door 8 to be delivered to the customer. It is to be noted that at this time the inclined guide plate 42 of the shuttle mechanism is almost in line with the chute 55 so that there is no substantial drop in the bottle. There is a slight drop due to the fact that allowance is made for the use of larger bottles in the machine. If a somewhat larger bottle is used then that larger bottle does not 'clear the edge 34 untilv the guide plate 42 is in line with the chute -5y hence no drop of the bottle takes place as the bottle rolls from the shuttle to the chute. If still larger .bottles are used At the same time the.

then the stops 38-319 and the ledge 3l are 'rplaeed so :as to allow 4the larger bottles tov pass through'the mechanism,

When `the shuttle is in its lowermost position, illustrated in :Figure 3, so that the bottle 5D is discharged, and the .bottle 6| enters'the lower circular guide portion 33, the bottle 62 is supported by the stop 38 and the ledge 3|.. The customer then raises the lever I6 or releases vthe lever so that the springs 52 raise it, thus causing the shuttle mechanism to move upwardly. lAs 4the 'shuttle moves .upwardly the stop l39 pushes the bottle 6| to the left from the position .illustrated in Figure 3, and the stop continues its upward movement until it passes above that bottle.` As

vthe stop '39 continues to rise the bottle then moves to the right until it encounters the guide plate 42 which prevents the bottle 6| from Vbeing discharged. That bottle is then in the same position asthat of the bottle 6D of Figure 2. During the same upward movement of the shuttle from the position illustrated in Fi-gure 3 the stop 33 forces the bottle 32 to roll upon the ledge 432 vuntil the Stop 38 rises above the center of the bottle 62. Continued upward movement of the shuttle causes the bottle 62 to roll down the inclined portion 32 under control of the stop 38 until the .bottle abuts against the vertical plate 3'|. At this time the stop 39 engages the bottle 62 of Figure 3, which is now in the position previously occupied by the bottle 6| of Figure 2. Thus there is a minimum amount of movement and agitation of the bottles. Y

It is to .be noted that when the shuttle mechanism moves downwardly from the ,position illustrated in Figure 2 the bottle 6| tends to rollin a clockwise direction down the vertical wall of the ledge 3|. Clockwise rotation of the bottle 6| tends to induce a counter-clockwise rotation of the bottle 62 above it. The bottle 62 is in contact with the wall 25. The downward sliding of the bottle 62 in contact with the wall 25 tends to resist the clockwise rotation of, the bottle 62 thus resisting rotation of the bottle 6|. `This retards the downward movement and also inhibits or even prevents the rotation or rolling that may tend to. take place, thus reducing the amount of agitationof the bottles.

vWhen the mechanism is coin controlled the dispensing unit is provided with a locking mech- .anism which normally locks the shuttle against downward movement when the particular select-.

l ed row. such as 2D, is empty, thus advising the customer to operate a diierent lever I6 which controls the shuttle mechanism of an adjacent row., such as the row 2|. The locking mechanism is released by the weight of a bottle at 68 in Figure 2, in the manner illustrated in the applica.- tion of Milton L. Smith and Robert Schwalb above referred to, to which reference may be had. Likewise the movable shuttle mechanism is provided with a full stroke mechanism, as shown in the Smith and Schwalb application, so arranged that upon initiation of movement of the shuttle in either direction the full stroke mechas nism prevents .reverse movement until the Shuttle has been moved its full stroke, at which time reverse movement is again permitted. Sincethis is no part of the present invention a description and illustration thereof is not deemed necessary, but reference to the application of Milton L. Smith and Robert Schwalb may be had for these features.

.In the description thus far given I have spoken of the springs 52 as being compression Springs normally urging the shuttle mechanism to the .position illustrated in Figure 2 and placed under compression when the shuttle mechanism is moved to the position illustrated in Figure 3. By this arrangement, as above described, a bottle is discharged when the shuttle mechanism is forced downwardly and thereafter the springs springs normally urge the shuttle mechanism tothe position illustrated in Figure 3. When this is the case the operator of the machine actuates the lever I6 upwardly, thereby tensioning the springs 52 and moving the shuttle mechanism rfrom the position illustrated in Figure 3 to the positions illustrated in Figures 2 and 4. That causes the lowermost bottle (6| of Fig. 3) to move into the position illustrated bythe bottle of Figure 2. At that time the springs 52 are under tension so that on release of the lever I6 by the.

operator the shuttle then returns from the position of Figure'2 to that of Figure 3, thereby discharging abottle. Under such circumstances thc initial operation of the lever I6 (upward) results in setting of the mechanism, and the release of the lever results in discharging of the bottle. This is of advantage particularly when the mechanism is used in conjunction with a full stroke mechanism which compels completion of an initiated operation of the lever I6 before the reverse operation can take place. In such an arrangement, with the springs 52 as tension springs, a customer commences the upward movement of the lever I6. The customer cannot obtain a bottle of beverage until after the lever has been moved to its uppermost position and then moved downwardly again. The customer is therefore sure to move the lever to its uppermost position, or to continue moving the lever upwardly until such time as he can move it no further. The release of the lever then causes the springs to move the shuttle mechanism downwardly to discharge a bottle. In an arrangement such as was rst described, wherein the springs 52 are compression springs so that the rst movement of the shuttle is downward resulting in the discharge of the bottle, there is a possibility in the case of a coin controlled dispenser that a bottle, especially a small bottle, may be discharged before the shuttle mechanism reaches the bottom of its stroke, and the customer having received his bottle of beverage will not `co-mplete the downward movement of the shuttle, so that the full stroke mechanism might prevent the automatic upward movement of the shuttle. This is not possible in a case where the springs are tension springs and the initial shuttle movement is upwardly, as above last described.

In compliance with the requirements of the patent statutes I have here shown and described a preferred embodiment of my invention. It is, however, to be understood that the invention is not limited to the precise construction here shown, the same being merely illustrative of the principles of the invention. What I consider new and desire to secure by Letters Patent is:
