It is to be understood, however, that the back of the cabinet may be omitted. 5 designates the main door of the refrigerator and 6 the touch control for the door. 1 represents the control buttons at the top edge of the refrigerator and 8 aventilating grille at the base of the refrigerator. 9 presents a vegetable bin door having an operating mechanism to be described later. i0 designates a pair; of grilles located on the top of the refrigerator used in conjunction with a pair of uninterrupted vertical flues or air passages l0 located in the rear corners of the refrigerator between the outside surface of the rounded re frigerator and the inside surface of a square or rectangular cabinet for the ventilation of the compressor chamber, .all of which will be described in detail further on. The outside wall of the circular refrigerator unit is designated by H and the inner wall of the refrigerator unit is shown by l2.

Spacing members 13' are located between the outer shell II and the inner shell [2 of the circular refrigerator. These spacing members'are of a height and width for proper alignment of the two shells of the food, ice cube making and tical support of the food compartment andv notched at If for support of the ice cube making and frozen food compartments. The spacing members may be suitably supported by braces located in the compressor compartment.

The refrigerator food compartment l4 has a floor l5. Compressor coils are shown. represented byv 6.

An ice cube making compartment is shown by I! and a frozen food compartment is designated as l8. The frozen food compartment has an additional door I! with a handle 20, the door being hinged at l9.

The compressor compartment generally is designated by 2|.

In the food compartment II are a number of revolving shelves 22, which shelves are supported by rollers generally designated as 23 and shown in detail by Figs. 3, 4, 5, 8, 9 and 10. These rollers are supported upon vertical strips 24, these strips having perforations 25 to permit up and down adjustment of the rollers. In the floor of the food compartment is a gutter 26 having a drain pipe 21.

In the ice cube making compartment I! are trays 28 and back-stops 29 and each tray has a cam lifter designated by 30.

In the frozen food compartment I8 is a suitably supported shaft 3| adapted to be rotated and upon this shaft are secured trays 32. In this frozen food compartment there is also a gutter 33 having a drain pipe 34.

The compressor compartment 2| has a door 9, which door supports a.vegetable bin 35. A handle for the door is designated by 36. In the compressor compartment is a pan 3! in which are located by-pass coils 38'from compressor to condenser. Both the aforementioned pipes, 21 and 34, drain condensation into the pan 31 and by means of the by-pass coils the condensation is evaporated. v

Referring to the main door 5, this door is hun on top and bottom pivots 39 and is self-closing by means of touch control 6, this door cooperating with pivoted angle 40 in connection with spring bolt 4| and keeper 42 located on refrigerator body. Also, there is a spring plunger 43 adapted to afford easy'opening of the door. IAISO the refrigerator cabinet has door jamb breaker strips or gaskets 44 attached thereto as distinguished fromv the usual strips .secured to the door itself.

The door 9 which supports the vegetable bin 35 is hinged upon pivots 45. This door is self-closing through spring and toggle mechanism comprising a tube 46 pivoted at 41 to bottom of frozen food compartment in which is located a spring 48 pivoted to the toggle joint 49 and strap 50 which is pivotally attached to the door at 52 represents a catch to hold the knuckle joint, 49 when door is open.

In Fig. 'l is shown a temperature controlled sealed compartment 53 for butter storage, this compartment being separated from the food compartment by door 54 hinged at 55. Also, in Fig. '7, a lamp 56 is shown with its reflector 51 housed into the inner shell of the food compartment.

As already stated, an important object of my invention is to provide a food compartment of my refrigerator with circular walls in which revolve circular shelves 22. To permit of easy revolution and support and centering of the shelving, I provide a roller arrangement generally designated by 22. A preferred form of rollerconstruction is shown by Figs. 3, 4 and 5 in which 60 represents a hori- 1 vertical rollers 68. The housing 8! has an integral pin 61 directed downwardly at an angle, which pins of a plurality of roller constructions 23 when inserted in openings of the vertical strips 24, support the outer edge of shelves 22 and thus permit them to be easily and safely revolved.

A modification of supporting roller construction is shown by Figs. 8, 9 and 10. In these figures vertical rollers are omitted, there being only a horizontal roller having a flange 68 against which the outer edge of the shelves contact. With this type of roller construction there is a supporting portion 69 for the roller, this portion having an integral downwardly'projecting pin 61 which cooperates with openings in vertical strips 24 for the same purpose as pin 61 of Figs. 3, 4 and 5.

Insulation throughout the construction is designated by Hi.

From the preceding description it will be evident that I have provided a refrigerator construction of exceedingly high efficiency and simplicity in which, by means of the revolving shelves, the necessity of the user of removing food from the front of the ordinary stationary shelves to obtain the desired food in the rear of the shelves. is eliminated. Moreover, by the use of the revolving shelves of my.invention there is no bindingof the shelves as is the case of the pull out type of shelves. In addition, the revolving shelves permit all food located thereon to be visible at a time when a particular food is needed. It will also be seen that my novel refrigerator construction permits it to lie flush against a wall, thus eliminating inaccessible dust accumulation.

Also, through employment of a rectangular cabinet with the revolving shelf arrangement, rear corner ventilating flues are provided for th compressor compartment.

Another advantage of my refrigerator construction is the location of the ice cube making compartment beneath the food storage compartment.

iii

zontal roller journaled upon bearing 6!, there In thus locating the ice cube making compartment no spillage is permitted to fall into the food compartment at a time when defrosting takes place or otherwise.

A further advantage of my construction is the provision of gutters and drains for the food storage compartment and frozen food compartment, thug eliminating the use of drip pans commonly use An additional advantage of myconstruction is the location of the gaskets upon the refrigerator housing as distinguished from being located upon the doors themselves. In placing the gaskets as heretofore described they are oiit of the way of the hand of the user of the refrigerator and, consequently, cannot be affected by such contact,

I have herein shown and described what I now consider to be a preferred manner of carrying out my invention but the same is for illustrative purposes only and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
