The, apparatusinclu'des a cabinet generally indicated", at, C in Fig. 1, which may be made up of a plurality of individual sections or refrigerated. compartments, or eachsection may be consider-edas a complete cabinet in itself. Inthe form. shown, the cabinet is made .up of a plurality" of individual; compartments with a separate ar- ,rangement, of cooling and bottle dispensing ape paratus. for each section or unit; and the descriptionand drawingswill beconsidered as applying to each, individual section of thecabinet' or to. the cabinet as a whole, The cabinet or each, section thereof comprises an outer insulated wal1.5,note particularly Fig; 2 and an inner casing, or bottle compartment liner 6 which is preferably comprised of sheet metal .or like materialhaving a high ratio of thermal conductivity and, is spacedfrom the wall 5 to. provide a compartmentfia for ,coolingcoils orianalogous means. The arrangement of the cooling coils is best;

shown. inliigsg l, 5 and. 6. The ,source of refrigeration is not shown but may obviously be of the mechanical type such as a, motor, compressorcondenser-unit or of the heat generator 8lbso rp-,v

tion or any'other suitable type. 'The line from the compressor or high pressure side of the system is, indicated, at I, said linejhaving] therein heat-exchangecoil 1 a,, and beyond this 0011 connecting with. expansion. valve 8, from which the refrigerant passjes through line 9 and union 90,

into a series of bottom] coils I0 and Illa and then upwardly, into sidecoils l I, and I la, the refrigerant returning through lines l2, 12a and union I 20, note Fig. 4, and then through line I 2a. to the source of refrigeration. A temperature control unit I3 (Figs. 2 and 6) is mounted in a separate storage compartment I4 formed in the cabinet in a manner to be described and this unit communicates through tube I3a with a temperature control coil I3b. The expansion valve 8 is provided with capillary tube I5 (Fig. 4) which communicates with the valve through line I 5a.

It will thus be seen that the inner compartment in which the bottles are disposed is cooled both at the sides and bottom, the cooling coils being located in separate compartments adjacent the main bottle storage compartment, generally indicated at I6, note Fig. 2, and shownwith a plurality of bottles B disposed therein. This arrangement of coils ensures maximum cooling efliciency with a minimum of coil length and space, while the location of the control unit ensures proper regulation at all times.

The entire casing 6 is preferably suspended as a unit by means of channels I1, note Fig. 4, which are secured to the upper side walls of the cabinet and rest on ledges or shoulders IIa provided by angle members secured to the adjacent outer insulated walls as indicated at Ill). The top of the cabinet is removable to accommodate insertion and removal of the casing and coil assembly, note Fig. 6 in conjunction with Fig. 4.

Considering, now, the dispensing apparatus, the

arrangement is such that when the door I8 at I the front of the compartment is opened, a bottle is automatically transferred from the cooling compartment to and held on theinner face of the door within convenientreach of the party opening the door, note the position shown in Fig. 2a. The mechanism whereby this is accomplished comprises a bottle dispensing wheel or magazine generally indicated at I9, which is secured on a shaft I9a and may be formed of a series of arcuate plates Welded together about a common axis to provide a plurality of magazine recesses I9b, each of which is adapted to receive a bottle and move the latter around until it reaches a gravity runway or chute 20. This runway is preferably of a length such as will accommodate a limited number of bottles but not of such, length or inclination as to impose undue weight on the bottles adjacent the door and particularly on the bottle in contact with the door and which is the next to be removed when the door is opened. The bottom of the runway is provided by wall 20a which comprises part of the wall 6 and this wall 20a is curved as it approaches the back of the main storage compartment to conform to the contour of the periphery of the dispensing wheel I9 and serves to retain the bottles within the recesses I 91) at this point without interposing any appreciable resistance to rotation of the wheel. The top of the runway is provided by wall 20b which wall also forms the bottom of the cold storage compartment I4. The door is hinged as at 2|, and on the inner lower face thereof there is mounted a bottle transfer or delivery device 22, see Figs. 2 and 2a. This device is formed with an arcuate inner wall 22a and a shoulder 22b, and the bottom wall 20a of the, runway 20 terminates in a downturned strengthening flange 200 within predetermined closely spaced relation to the arcuate wall 22a,

permitting free movement of the latter when the door is swung. A bottle-retaining wall 220 is formed on the one end of the device 22, and this wall is preferably inclined and has its edge rolled P to strengthen and stiffen the same.

It will be seen that as the bottles roll down the runway 20, the foremost bottle will engage in the pocket formed by the parts 221), 220, so that when the door is opened the foremost bottle will lie on the inner face of the door as indicated in Fig. 2a. The next bottle in the chute will roll down until it touches the inner edge of arcuate wall 22a, as shown in Fig. 2a, and all the bottles in the chute which have followed said next bottle then will be held without movement until the door is closed, whereupon they will all move slightly as the lowermost bottle rolls into the now empty pocket formed on the member 22.

The bottle-dispensing or magazine wheel I9 is preferably of a width such as to substantially span the width of the main bottle compartment, or of a width such as will prevent a bottle from falling off of the wheel or becoming cooked or misaligned. The top wall 23 of the compartment I4 provides a deflector or guide, note particularly Fig. 2. The rear wall of the main bottle compartment is provided with a deflector or guide 24. The deflector walls 23 and 24 constitute, in effect, a hopper for the bottles which guides the same into the recess IQ?) of the wheel I9. These members 23, 24 may be made of sheet metal or the like and are easily fabricated. The rear end wall 23a of the compartment I 4 forms the adjacent side wall of the hopper, the recesses I9b of the wheel I9 being empty as they pass this point.

The dispensing wheel or magazine I9 is intermittently rotated, when the door I8 is opened and closed, through the medium of an indexing disc 25, note particularly Figs. 3 and 7, which is mounted on the end of shaft I9a carrying the dispensing wheel IS, the said disc being mounted in the coil compartment 6a. The disc is formed on its periphery with a series of cam surfaces terminating in one-way teeth or notches 25a which are adapted to be engaged by the active end of gravity pawl 26 pivotally mounted on the lower end of an arm 21 which straddles the disc, the upper end of said arm being pivoted on the outer end of shaft I9a. The arm 21 has pivotally connected thereto a link 28, which extends forwardlyto a point adjacent the door opening. A pivot member 29 is projected through the front end of link 28 and has mounted thereon a bearing member 2911, note Fig. 11, on which the link is directly mounted, said bearing member being formed with a flange 29b which is welded to a member 290 connected to the door. Thus when the door is opened, it pulls the link 28 forwardly, and through weighted pawl 26, arm 2'! and indexing disc 25, imparts a rotary step to dispensing wheel I9.

The wheel actuating mechanism including disc 25, arm 21, pawl 26 and link 28 is housed in the coil compartment 6a, and this mechanism may be installed on one or both sides of the door and operatively connected to .both ends of wheel I9.

To limit the opening movement of the door, a link 30 is connected at its upper end through the medium of a slotted opening 30a with a screw or like member 30b which is anchored to the frame of the door, and at its lower end is pivotally rlgiourited on the outer end of bearing-29a, note When the door is opened, the link 28, pawl 26 and arm 21 move from the full line position shown in Fig. 3 to the dotted line position, thepawl 26 engaging one of the teeth or. notches 25a of the. disc 25, imparting a partialor step rotation to, the dispensing wheel I9. When the door is closed the links 30 and 28 and pawl 26 movebackto the full line position. d j

To prevent back or reverse rotation of the disc 25 and dispensing wheel f9, a one-way latch 3| is pivotally mounted on a stub shaft 3la adjacent the disc 25 and isprovided with a pin 3Ib adapted to engage the teeth or notches 25a of the disc 25. j

The door is provided with a handle 32 mounted on a bracket 32a anchored to the door. A latch assembly 33 is provided and is fixed in a recess formed in the inner face of the door, see Fig. 10, said assembly includinga latch nib'sta adapted toengage a spring catch 34 se'curedin a recess 34a formed in the door frame.

From the foregoing description taken in conjunction with the drawings, the operation of the apparatus will be readily understood. 'The bottles maybe disposed in the cabinetin horizontal position, and the entire cabinet filled to capacity. The bottle dispensing wheel ormagazine 19 will be given a partial turn, or step-by-step rotation whenever the door is opened and closed; and each time this occurs, a bottle is carried around by the wheel Hi to. a point-where it will roll by gravity down the runway 26, the foremost bottle I lying in the pocket formed bythe member 22. ,When the door is opened the bottleisbrought to the position shown in Fig. 2a within ready reach of the party opening the door and may be easily and quickly removed and the door closed. This type of dispensing mechanism will operate smoothly and surely irrespective of whether or not the cabinet is completely filled with bottles or only partially filled. This is due to the fact that the wheel I9 together with the deflector walls 23 and 24 provide in effect a feed hopper which inte'rposes a barrier between the load of bottles and those on the gravity runway 20. As each bottle is taken from the lower end of the chute a fresh bottle is moved into gravity feed position at the upper end thereof. The apparatus will continue to function easily and smoothly down to the last bottle.

A common fault with cabinets of the type utilizing a dispensing wheel in conjunction with a feed hopper is that the bottles tend to form an arch or bridge across the opening to the dispensing wheel and jam at this point. In order to avoid any tendency towards bridging and jamming across the opening to the dispensing wheel in the present instance, said wheel is so located with respect to the hopper opening and the outer tips of the wheel so extended that said tips strike one or more bottles in the hopper each time the wheel is rotated and raise them sufficiently to break up the arch or bridge.

The compartment l4 formed by the walls 201), 23 and 2311 forms a convenient storage place for various food products or different types of beverages, this compartment being so located as to be readily accessible from the door opening without permitting an undue rush or escape of cold air from the main bottle compartment.

The entire arrangement is such as to promote refrigerated within the described cabinet; hence,

the references to bottles in the description and claims are not limitations but are merely descriptive and illustrative.
