f 4 Claims.

My present invention relates to an improved vending machine of the coin controlled type in which'is also incorporated a refrigerating or cooling system for the bottled beverages stored in the machine. I preferably utilize a dual or two-sec- `tion machine for vending or dispensing,l singly, the bottled goods from the separated sections or dual machines, and a single intermediate cooling chamber is employed to provide a compactly arranged, and self contained vending machine.

By the use of two separate, or dual dispensing mechanisms ample storage is provided for a large quantity of bottles, which bottles may be of two different sizes, or the two sets of bottles may contain diierent beverages, thus facilitating the sale of the bottled goods, and at the same time reducing the frequency with which the usual vending machines must be relled.

Means are provided for controlling the move- Vments of the bottles from successive interior storage chutes to a gravity feed chute, thence to an arrester chute, and finally to the discharge chute and its trough, in order to prevent jamming of the bottles; to provide for a free flow of the bottles under control means; and for iinally clischarging a single bottle from the dispensing machine after the proper coin'has been deposited in the com chute.

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be fully set forth and claimed. In the accompanying drawings I have illustrated one example of the physical embodiment of my invention wherein the parts are combined and arranged in a dual vending machine, but it will be understood that changes and alterations may be made in these exemplifying structures, within the scope of my claims without departing from` Y the principles of my invention.

Figure 11 is a horizontal sectional view at line Il-II of Figure 10 showing a bottle between the duplex or double acting discharge gates together with an abutment in the path of the neck of the discharging bottle which causes the bottle to turn through an arc of 90 degrees and therefore slide out of the discharge chute in a longitudinal position with relation to the discharge chute.

Figure 12v is a view similar to Figure 10 but with the duplex discharge gates adapted to pass a single bottle of less diameter than the gates of Figure 10. n

Figure 13 is an enlarged front elevation of the cushioned stop at one end of the arrester chute,

and Figure 14 is a sectional view at line I4-I4 of Figure 13.

As before stated I preferably carry out my invention in the form of a dual or duplex vending machine, from which two sizes of bottles may be dispensed, singly, or the dual machine may be equipped to dispense two sets of bottles singly,l of the same size and containing two different liquid beverages.

of the cabinet. At I8, I8 two emp indicators' are provided adjacent the coin slots to announce the exhaustion, or near exhaustion, of the supply of bottled beverages in the two sections of thei vending machine.

A removable panel I4 is located centrally of the cabinet near the bottom thereof, and at I5 in Figure 1 a device is attached to the front of the cabinet for use in removing a bottle cap.

As shown in Figure 4 a horizontal partition I6 separates the upper storage chambers and the intermediate cooling chamber from a bottom compartment Il, in which arefrigerant compres- A eration a description of one sor I8 of suitable type is located, and the two pipes I9, I9 passing upwardly through the cooling chamber communicate with the heat ex change unit 20 supported at the top of the cooling chamber. 'Ihis unit includes an electric fan 2| operated from a suitable source of electric supply, and the usual louvres 22. From this unit the cooled air is distributed throughout the cooling chambers and storage chambers, and as indicated the walls and doors forming the storage compartments and cooling chamber are insulated as at 23 to insulate the interior of the machine.

Inasmuch as the dual dispensing mechanisms are substantially similar in construction and opdispensing mechanism will suiiice for both of them.

As indicated in Figures 4, 5, and 6 two upright, open partitions 24, 24 are spaced apart in the interior of the cabinet to form the two bottle storage compartments 4 and 5 and the central cooling chamber l, and the bottles are deposited in their respective storage `chutes and the upper part of the compartments through the open double doors 2, 2 and 3, 3, the bottles being inserted butt end rst. As seen best in Figure 3 a vertical series of spaced inclined shelves 25 is 4arranged in a storage compartment to form storage chutes declining toward the rear of the cabinet, and the bottles stored in these chutes, as well as in the top of the compartment above the chutes, are held against accidental rolling movement by exit gates that are manually closed. These gates are held in closed position by bottles in a vertical feed column and successive exit gates beginning with the top gate are automatically opened as the height of the feed column diminishes.

In their gravity-rolling movement down the inclined chutes the bottles are guided and heid in proper alinement by means of guide rails 26 that extend longitudinally of each storage chute for contact with the butt-ends of the bottles and the rails are secured to an inner partition 24 of the cabinet. These rails are adjustable toward and away from the row of bottles, and they are secured to the partition as by pins or bolts 21. As

seen in Figure 5 removable ller blocks 28 may be mounted on the pins between the guide rails and the partition so that the rails will guide bottles of one size, and these lier blocks may beremoved to permit the guide rails to be moved to position against the partition to accommodate bottles of greater length.

At the rear of the interior of the storage compartment a vertical feed chute 29 is provided. having a guide strip 30 xed to the inner face of the back wall of the cabinet, and as seen in Figure 8 this feed chute 29 is slightly wider than the diameter of the bottles forming the feed column therein, but not of sufiicient width to permit jamming of the bottles in the feed column.

An automatically opened exit gate is provided at the rear end of each storage chute, and as the height of the feed column decreases, the exit gates of the storage chutes are successively opened to the vfeed chute 29 to permit the bottles in successive chutes to roll into the upright feed chute 29, thus forming the upright feed column of bottles as best seen in Fig. 3. r

In the enlarged detail view in Figure 8, it is assumed that the bottles in the top of the storage compartment above the chutes have passed down into the feed chute 29, and the top, automatically opened exit gate, which had been held in closed position by the'bottles in the upper end of the feed column, has been swung open, while the exit gate of the storage chute second from the top of the series of chutes is held closed by the bottles rolling out of the top storage chute, into the feed column.

As best seen in Figure 9 the gate 3| is of Vrectangular shape, and hinged at 32 to the shelf 25 above; at least one of the hinges having a spring 33 which swings the gate outwardly and upwardly from the chute as in Figure 8, when the gate is free to swing. Beginning with the bottom storage chute, the gates are manually closed, and as the storage chutes and feed chute are lled with bottles, from the bottom up, each succeeding gate is manually closed against the tension of spring 33 and against a stop 34 of its chute. A latch device is provided for each gate comprising an angular trip lever 35 pivoted at 36 in a slot f the gate, and a coiled spring 3l tends to swing the trip lever toward the feed chute.

After the gate is closed against its stop 34 this angular trip lever is manually pushed from its upper unlatched position of Figure 8 to the lower latched position in the same figure. As the lever is pushed inwardly toward the chute a latching detent or latch 38 suspended from the short inner arm of the lever slips into a socket 39 of the bottom of the chute and locks the gate against opening by pressure imposed on the gate from the row of bottles in the chute. To confine the latch and the gate in closed position I utilize a presser plate 40 hinged at 4I at the outside of the gate. Thus, after the latch for the gate has been set, this presser plate is manually turned down over the slot in the gate and against the free end of the angular lever, and the bottles in the feed column pressing against this plate as Well as the door, hold the door closed.

As soon asthe top of the feed column of bottles passes below a gate the presser plate and gate are freed from the laterally disposed weight of the bottle, the spring latch lever is swung outby preventing an excessive load on the control and discharge means for the single bottles I provide an inclined arresting chute 42 at the bottom of the feed chute, and this arresting ch'ute has an end vertical port '43 which opens downwardly into a discharge chute 44, and the two discharge chutes of the dual machine terminatein the troughs I and Il indicated at the front of the cabinet in Figure 1. f

At the bottom of the feed the gude'strip 30 for the feed column of bottles, is thickened as at 45 in order to guide the bottles in the column into an off-center position with relation to the feed chute, thuspreventing the column of bottles from assuming a straight line column.

The guide strip 30, and its thickened lower end 45 are preferably of resilient material to prevent .rattling of the bottles in the feed chute, and at the bottom of the feed chute a resilient buffer 46 protrudes into the chute to receive the impact from descending bottles as they successively reach the bottom of the feed column.\ A similar device,

as bumper 41 is located in the end of the arrest- The bumper 41, of rubber or resilient material is mounted in a slot in a wall 48 of the chute,

and the bumper is provided with a back plate 49 outside the chute, while the front face of the bumper projects'into the chute to receive the impact of bottles moving through the chutes. The back plate 49 is mounted by two bolts 50 in the wall of the chute, and springs 5I are interposedbetween nuts 52 on the threaded ends of the bolts,

as best seen in Figure '14. The nuts 52 may be turned to increase or decrease the tension of the springs and thus vary the resistance of the bumper offered to the row of bottles in the arresting chute. Thus the buffer 46 receives and softens the impact of the lowest bottle in the feed column, reduces noises of the falling bottles, and serves to hold the column against jamming. bumper 41 together with the arresting chute, relieves the bottles in the discharge chute '44 from the weight of the feed column of bottles, and the successive discharge of single bottles from the chute 44 is rmore readily controlled.

'I'he discharge or dispensing of bottles, one at a time, from the discharge chute to the receiving trough I0, as in Figure 3 is initiated by manipulating the coin controlled appliance at 8, and this appliance includes a slide rod 53 supported in slide block 54, which slides in a track 55 forming part of a frame xed to a suitablesupport in the interior. of the cabinet. The sliding movement of the rod and block inwardly controls the movement and position of adouble discharge gate comprising panels or plates 56 and 51 that move in slots 58. These panels or double acting discharge gates are each pivoted at 59 to the opposite ends of a cross-head 60, and the cross-head is centrally pivoted at 6l on suitable supports as 62 so that as.

the cross head is rocked the two gates 56 and 51 are moved up and down to discharge one bottleand retain the next one. iThe rocking of the cross head 60 is accomplished from the slide 53 of the coin controlled apparatus, which slide has a slotted depending arm 63 which moves with the slide, and a screw bar 64 which is threaded in the cross head for adjustment is connected with the slide arm 63 by a pin 65. It will be understood that the dual gates 56 and 51 are spaced apart a The4 ' slot 9 as in Figure '7, the dotted slide devices carry with them the slide rod 53, and in Figure 10 it will be seen that this slide movement swings the screw bar 64 over to the left and the cross bar 10 als'o swings to lower the gate 56 and raise gate 51. 'I'he gate 51 thus frees a bottle to roll down the discharge chute, and upon automatic return (as by a spring) of the slide rod to the right, the gates assume the position of Figure 10, thus dis- 15 charging one bottle and then retaining the next one in the place of the first or discharged bottle.

The bottles are thus successively discharged, one at a time, the storage chutes are successively emptied into the feed chute, the feed column of 20 bottles gradually decreases in height, and the. ar-

resting chute and discharge chute are finally emptied.-

'I'hebottles are arranged transversely of the chutes so that they may readily roll to the dis- 25 charging lchute, but after thedischarged bottle passesthe gate 51, the head portion or neck encounters a. block 66, preferably of rubber that is fixed to the bottomo f the discharge chute in the path of the neck portion of the bottle.l Thus as 30.

seen in Figure 11 the -neck` portion of the lower bottle, when it is discharged, will encounter the block 66 and` hold the neck portion tvhile the .heavier body portion of the bottle will swing around through an angle of degrees into a 35 longitudinal position alined with the discharge trough, and then the discharged bottle slides butt first into the receiving trough l0 or Ii as the case may be.

In Figure 12 the dual gates are arranged closer 40 together than in Figure 10 to accommodate bottles of small diameter.

In Figure 10 the gates are in position with theirhinge ears 61 at'the inner sides of the gates thus outwardly spacing the gates, while in Figure 12 the dualgates are reversed with their hinge ears at' the outer sides of the gates, so that the gates are inwardly spaced.

After the contents of a dispensed bottle have been consumed, the empty bottle is 'slipped into a 50 pigeon hole or pocket forming part of two series of receptacles 68 and 69 located at opposite sides of the bottom chamber i1 with their mouths open A at the front of the cabinet. The pockets decline empty sign is displayed at I3 shown at the 65 i front of the cabinet in Figure 1.

As indicated in Figures 4 and 5 cooling chamber 1 may be employed for refrigerating purposes, and bottled goods may be stored therein as illustrated. 70

From the above description taken with the drawings it will be apparent that I have provided a vending machine of large capacity that is at the same time compactly arranged to occupy a minimum of space, and which is self contained, 75

requiring only the usual electrical cord someotion to an outlet box or source of electrical supply for the compressor and the empty signals.

latch are held closed vby lateral pressure from the column of bottles, and the gate is automatically opened when the lateral pressure ceases.
