19 claims.

This invention relates to improvements in machines for vending bottles, and has for an object the provision of an insulated cabinet having 'a plurality of columns of bottles therein, means in said columns for isolating said bottles-from physically contacting each other, means tokeep said bottles cold, and means to vend said bottles therefrom'.

Another object of the invention is the provision in a vending machine, of a plurality of columns having the bottles therein horizontally disposed, and means in each column for physically separating thebottles from contact with each other.

A further object of the invention is the provision in a bottle vending machine, of a vertical column for said bottles, a continuous band or belt of exible material supported for rotation at points near the top and the bottom of the column, said belt having tabs secured thereto in spaced relation of the order of the diameters of the bottles, said tabs extending crosswise in the column, and each tab extending between and separating two adjacent bottles.

Yet another object of the invention is the formation of the belts and the tabs of fabrics of extreme flexibility and suitable for long wear and continuous service.

In the embodiment herein shown and described to illustrate the invention, the cabinet is provided with a number of vertical columns. .Each column has a belt therein formed of canvas or any other suitable material, and pulleys at the tops and bottoms of each column rotatably support said belts. Each belt hasl stitched or otherwise secured thereto a plurality of tabs which lie between and prevent the bottles from actually contacting each other.

as the homes are vendee, the beit moves dwnwardly due to the weight of the bottles, and the tabs may have their outer edges hemmed or otherwise thickened to prevent the tabs from pulling out from between adjacent bottles.

The columns are larranged to be vended from the columns successively as will hereinafter be described. A suitable refrigerating system is provided for cooling the cabinet, and a motor driven fan in the bottom of the bottle compartment is provided for circulating the cold air.

Referring to the drawings:

Figure 1 is a front elevation of my new bottle vending machine;

Figure 3 is a sectional elevation showing the general arrangementof the columns, their belts, the gates between the columns, the discharge device etc.;

Figure 4 is an enlarged fragmentary view of a portion of Figure 3;

Figures 5 and 6 are fragmentary views illustrating the action of the machine in vending bottles;

Figure '7 is a cross-sectional view as seen along the line 'l-l of Figure 3;

Figure 8 is a cross-sectional view as seen along the line 8-8 of Figure 3;

Figure 9 is a detail view of the bottle discharge of hinged doors between the columns.

An insulated cabinet 20 has a fixed front 2|, supporting 'a panel 22 carrying the coin mechanism and bottle releasing means to be presently described.

The side 230i the cabinet 2li is hinged at the back and has a lock 2t engaging the front, whereby access to the bottle columns in the right half of the machine may be had. Likewise the opposite side 'of the cabinet is provided with a locked door through which access to the bottle columns in the left half of the machine may be had.

Referring now to Figlre 3, it will be seen that in addition to the insulated

doors

23 and 25, the stationary part of the cabinet includes a rear insulated wan 26, the front insulated wau above l referred to and the top and bottom walls 21. and 28 respectively.

Beneath the bottom insulated wall 28 is an uninsulated compartment 29 for the high side of the refrigeratin'g system. The low side or cooling unit 30 is mounted in the cabinet, for example, adjacent to the rear wall 26.

Within the insulated compartment is a frame-v work including a front member 3l and a. rear and within the opening 36 is Figure 2 is a right side elevation of the may chine;

.member 32, joined by a top member 33 which may be perforated, and Joined by a. bottom member 34. The member 3l is also perforated and slants downwardly toward the delivery openings which will presently be described.

Below the bottom member 34 is a plate 35 which is preferably level, and is also perforated. A circular opening 38 is formed in the plate 35, mounted a, fan 3.1, carried on the shaft of a motor 38. 'I'he motor 38 is' positioned below the plate 35, in a compartment I9 formed between the plate 35 and the The motor is connected across the terminals of the refrigerating motor of thehigh side so that while the high side is running, the. motoras runs and circulates the cold air throughout the insulated compartment.

' Within the

framework

3 I, 32, 33, 34 is mounted a, plurality of vertical members 4,-4i, 42, 43, and 44, which define vertical columns for the bottles to be vended. A vertical plate 45 divides the interior of the frame work in half, and

thevertical members

44, 4I, 42, 43, and 44 just referred to are positioned in one of said halves. Likewise vertical members 40a, 41a, 42a, 43a and 44a are. mounted in the other half, as may be seen in Figure 8:

All of the vertical members are in the form of channels, and these channels are identical except in length and half of them are rights and the other half are 1efts. ,A description of one of them should therefore suilice for all of them. Referring to Figure 11, the sectional view therein may be considered as taken through one of the members, for example 4|. 'I'he member includes a channel having a fiat portion 46 with

angular portions

41 and 48 formed integral therewith. The angular portions 4l and 48 have aligned holes formed therein, supporting a shaft 49 which in turn, pivotally supports a tube or sleeve 50. The tube 50 may have its interior lubricated so that it may freely rotate on the shaft 49. A collar I is secured on the shaft 49 -by means of a pin 52 extending therethrough, and this collar` prevents the tube from moving endwise on the shaft.

It will be understood that in each channel there is a shaft and tube arrangement, such as above described, at the top of the channel and a second tube and shaft arrangement at the bottom, cooperating in a manner to be presently described. Y

It may be desirable to have one shaft in each column adjustable with vrespect to its mate. In Figure 10, slots 53 are provided at the tops of the columns instead of aligned holes.

I'he ends of the shafts 49a are threaded and provided with nuts 54 for locking the shafts in adjusted positions. A belt 55 spans the tubes or rollers 50 (which form pulleys) and as this belt is moved, in a manner to be presently described, it rotates the rollers 50 on the shafts 49.` The belts are preferably of a width substantially equal to'the lengths of the rollers, which are in turn about equal to the lengths of the straight portions of the bottles. This leaves a substantially wide open area through which the cold air may be circulated for cooling the bottles.

Each belt is provided with a plurality of tabs 56 which may be formed of a web of fabric,

' leather, or other material. Each of the tabs has one end 51 pointing downwardly and stitched or otherwise secured to the belt, and the outer end 58 folded back on itself and hemmed. 4 Between each two bottles is a tab 5B, and the hemmed end 58 obviates any tendency for the tab to pull out from between the bottles.

Figure 3 shows the cabinet as viewed from the y left side, with the door 23 open, after the same has been completely loaded with bottles. It will be noted that the

channels

40, 4l, 42, and 43 face the right, as viewed in Figure 3, and that the channel 44 faces the left. A vertical plate El is .mounted between the

channels

43 and 44 and serves as a guide for keeping the bottles in the column formed therebetween substantially in alignment. This prevents any of the vbottles from jamming therein.

At the bottom of the channel 4I is a gate 52, having

vertical arms

63 and 64 positioned in slots formed in the channel, and hinged thereto at B5 Y and 66, Figure 12. The lower end of this gate is lplate 6l in the same manner. It is also understood that the columns in the other half of the compartment have similar gates which function in the same manner.

Assuming that the columns 40 to 44 are all loaded with bottles as shown in Figure 3, the delivery mechanism, to be presently described, first deliversbottles from the bottom of column 40. As the bottom bottle is delivered, the others move down so that the one next to the bottom takes its place, and due to the weight. of the bottles, the belt moves down one tab space for each bottle delivered until the top bottle in column 40 reaches the position 60A. When the top bottle reaches the position shown in Figure 5, it will be noted that the gate 62 cannot open yet. However when the bottle moves down one more step to the position 60A, .Figure 6, the gate 62 is uncovered and opens, permitting the bottles to then be fed from column 4l. When the top bottle in column 4l reaches the position BOB, the gate 62a isuncovered, and the bottles are fed from column 42.

It will be noted that the

positions

60A and 60B above referred to are in contact with the slanting bottom plate 34, so it may be said that whenever the top bottle of any column reaches the bottom plate 34, the gate of the next succeeding column is released and the latter starts feeding bottles until its top bottle reaches the plate 34 etc.

As may be seen in Figures 4 and 5, the tabs on the upwardly moving portion of the belt lie at between the surface of the belt and the inside surface of the channel, In reloading the machine, the operator opens the door on one side, turns the belts to positions where the tabs project across the column. Of course the tabs sag downwardly somewhat like the tab 56h in Figure 6. Beginning at the bottoms of the columns, the bottles are pushed endwise and neck first into the co1- umns, making sure that a tab separates each bottle from its neighbor. The necks of the bottles 'form entering wedges and facilitate the job of reloading. The operator must of course make sure that the gates are closed. When one side is reloaded it has the appearance of Figure 3. The operator may then close the door on that side, open the door on the opposite side and reload it in the same manner. A

In Figure 3 it will be noted that the front wall 3| has an opening 61 formed therein. This opening is due to the thickness of the wall and is therefore in fact a small compartment. It is elongated and is large enough for a bottle to pass freely therethrough. Surrounding the outer end of the opening 61 is a rectangular member 68, preferably of non-metallic material and therefore4 a poor conductor of heat. Hingedly mounted on the rectangular member 68 is a door 10 having an elongated depression 69 formed therein. The door 10 is provided with a knob 'Il to facilitate assaa'ss outer sliding panels cooperative in a. see-saw ar- Y rangement. The inner panel 13 is slidably mounted in ways or guides 1l, and when positioned at the bottom of its travel, isolates the opening 61, which might be termed a "unit bottle compartment, from the interior of the cabinet 'I'he panel 13 has one end of a connecting rod 'l5 joined thereto by means of a pivot pin 18, the other end of the connecting rod being joined to an arm 'l1 by means of a pivot pin 18.' The arm 11 is keyed or otherwise iixed on a shaft 19 passing through the front wall 3i. This shaft may be i'ormed of non-metallic material to reduce heat leakage into the cabinet. On the outer end of the shaft 191s mounted a disc @0 which is also keyed or otherwise xed thereon. The purpose of this disc will presently be described.

The outer panel 8i is slidably mounted in a slot @da formed in the rectangular member 88 and is further guided by the extension 82 on member 68. A connecting rod at has one end pivotally connected to panel 8| by means of pivot pin 8d, and its other end pivotally connected to the disc 8d by pivot pin B, see also Figure 9. A knob BB is pivotally mounted on a shaft 81 carried by the disc at. Y

When the knob t@ is moved to the left as viewed in Figure 9, the disc im, the shaft 'I9 and the arm 11 are all moved in a counter-clockwisedirection,

' the connecting rod 83 is 'moved downwardly and therewith, the outer panel @I moves downwardly. At the same time, the connecting rod 1b moves upwardly and therewith the inner panel 'i3 moves upwardly also. As a result the panels arrive at the positions shown in Figure 6. The inner panel 18 has raised, permitting a. bottle to roll into the single bottle compartment G1, and the outer panel 8l has closed so that the |bottle comes to rest against it within said single bottle compartment. The spring 8B tends to urge the disc 80 in a clockwise direction so that when the knob 36 has been turned and released, the inner panel moves down between the two left hand bottles Figure 4 and closes oi the single bottle compartment from the interior of the cabinet, and at the same time the outer panel rises to its normal position so that when the door is opened the bottle rolls from the single bottle compartment into the depression 89 for easy removal.

I employ two such delivery devices, but since they both operate in the same manner, only one need be described in detail. A panel casing 22 houses the delivery mechanism, arcuate slots 89 and 89a being provided to deilne the movements of the knobs 86, 86a.

Since the other delivery mechanism'is identical it will not be herein described, but like parts thereof bear the same numerals with the addition of da."

The coin mechanism 80 forms no part of the present invention, therefore it need not be described in detail. A coin slot'Ql is provided to receive the coins, anda coin return receptacle 82 receives the returned coins afterthe coin return buton 91 is depressed. Interposer levers 95 and 84a are pivoted on a supporting shaft 95, which maybe supported by the wall 2l and the iront panel 22, and are normallyvpositioned horizontally with their outer ends in line with the shafts 81 oi the knobs 8B, 86a, suitable stops (not shown) being provided for deilning the lowest positions of these interposers. When in this position they have their ends in the path of travel or the stud shafts B1 supporting the knobs 86 and prevent either disc from being turned.

Movable members

83 and 83a project oppositely from the coin mechanism and they are respectively connected to the interposers 94 and 94a by connecting rods 9.8 and 86a.

When a coin of the proper value is dropped in the slot 9| and enters the coin mechanism, the outer ends of both of the members 93 and 93a are raised, thereby raising both of the interposers.

This permits either the knob 86 or 86a to be opl and permits the release of the second knob and the delivery mechanism associated therewith; therefore one customer does not have to stand back and wait for the one before him to finish a delivery operation.

As described before, after a knob is moved as far as it will go, and then released, the bottle goes into the single bottle compartment and is available as soon as the door 10 (or la) is opened.

Although I have herein shown and described embodiment of the invention by way of example, it is obvious that many changes may be made in the arrangements shown without departing from the spirit of the invention as defined in the appended claims.
