' s claims. (el. s2- 116) This invention relates .to refrigerators of the self-contained type in which the cooling unit-in the refrigerating chamber is 'connected to a motor and compressor and condenser unit incorporated 5 in the unitary structure of the refrigerator body.

One object of the invention is to provide an improved construction and arrangement whereby the said motor and compressor and condenser unit is disposed vertically in an Yoffset position, with relation to the vertical axis of the refrigerator, so that the space for forming the refrigerating chamber is not occupied by anything other than the refrigerating unit and the shelving necessary for supporting the food, al1 within the symmetrical and unitary structure of the refrigerator Another object is to provide an improved construction and arrangement whereby a refrigerator shelf is provided, of a size and-shape to iit the rectangular interior of a refrigerator having a rectangular body, said shelf having rotary supporting means incorporated in the flat level construction thereof, which can be rotated about a vertical axis, or axes, to bring any particular article of food or other object into position to be conveniently removed from the front of the refrigerator body.

It is also an object to provide certain details and novel features of construction tending to increase the general emclency and desirabilityv of a self-contained and unitary refrigerator of this particular character.

To the foregoing and other useful ends, the invention consists in matters hereinafter set forth' and claimed, and shown in the accompanying drawings in which- Fig. 1 is a perspective of a refrigerator embodying the principles of the invention.

Fig. 2 is a horizontal section on line 2-2 in Fig. 1 of the drawings. Fig. 3 is a view similar tp Fig. 1', showing a different form of the invention.

Fig. 4 is a horizontal section on line I--4 in Fig. 3 of the drawings.

Fig. 5 is a view 'similar to Fig. 1", showing a different form of the invention.

Fig. 6 is a horizontal section on line 8 8 in Fig. 5 of the drawings.

111g. 'l is a horizontal section on line 1-1 in Fig. 5 of the drawings. Fig. 8 is a detail view showing a particular form of shelf for the refrigerator shown in Fig. 5 of the drawings. t

Fig. 9 is a similar' view showing another form of 55 shelf.

Fig. v10 is an enlarged detail section of a portion of one of said shelves. t

As'thus illustrated, referring to Figs. 1 and `2 of the drawings,.the invention comprises a rece tangular refrigerator body I provided in the interior thereof with a cylindrical refrigerating chamber 2, andwith a suitable door 3 at the front thereof. In one rear corner of the refrigerator body there is a vertical sub-chamber, preferably round or cylindrical in form, as indicated at I, with an air inlet l at the bottom thereof, and with an air outlet B at its top or upper end. In this sub-chamber, a suitable electric motor 1 is supported near the bottom thereof, and above this motor there is a compressor 8 of any suitable or desired character, with a fan` 9 at the upper end of the motor and compressor shaft, and a condenser coil I0 is provided above said fan., whereby the latter operates in the usual manner"` to condense the refrigerating fluid into liquid, in the usual and well understood manner. The cooling unit may be of any suitable or desired character,

as indicated at il in Fig. 2 of the drawings, and is connected with the compressor or pump 8 and the condenser coil lil in any suitable or desired manner. Thus the vertical motor and compressor and condenser unit is disposed vertically in an offset position, relatively tothe vertical axis of the refrigerafr body, and is enclosed in a vertical subchamber disposed entirely outside of the refrigerating chamber.

In Figs. 3 and 4 the construction is similar, bu in this case the entire refrigerator body I2 is cylindrical both outside and inside, but is provided on its back with an extension i3 in which the vertically ,disposed motor and compressor and condenser` unit is enclosed, so that a round refrigerator is provided which can be placed in the corner of a room, as indicated in Fig. 4 of the drawings. In Figs. 5, 6, and '7,Jthe construction is similar to that previously described, but in this case the refrigerator body I4 is rectangular both outside and inside, so that the refrigerator has a rectangular refrigerating chamber which contains the cooling unit I6 and the shelving i6 for the food. Also, in lthis case, the vertically disposed motor and compressor and condenser unit comprises a combined motor and compressor I1, so

that the entire unit is shorter and does not extend the full height of the refrigerator body. but nevertheless this `unit is disposed in a sub-chamber I8 in one corner of the rectangular refrigerator body, preferably in the upper portion of the latter, so

that the space below said sub-chamber is avail-l -able as part of the refrigerating chamber, asindicated in Fig. of the drawings.v

As shown in Figs. 6 and '1, s' fiat shelf' 'isis provided, for. the food, having a single rotary secported on the under side of the shelf. Thus the be-required to have round or circular edges.

section 20 can be rotated about a vertical axis, 'to facilitate removal. of the food or other articles therefrom, through the front of the refrigerator, when the door 23 is open. The side edges 24 ofv the said shelf slide into the refrig erating-charnber. on shoulders 25 formed on the interior of the refrigerator body. Thus the shelf and its rotary section can be conveniently and -effectively used in a rectangular refrigerator, one

that has at least a rectangular interior. In Figs. 8 and 9 the two shelves shown are of similar character, being rectangular in form, but in Fig. 8 the shelf has two rotary sections 28 andr 21 disposed as shown, while in Fig. 9 the shelf has a. single large' rotary section 28, the axis of 4the latter being coincident with the vertical axis of the refrigerator body, whereas in Figs. 6,V '7, and 8 the axes of rotation are offset and are some distance from thevertical axis of the refrigerator body. i

It will be understood, of course, that in Figs. l to 4 inclusive the shelving inside the refrigerator body can be of any suitable or desired character and that it may have, if desired, the rotary sections similar to those shown in Figs. 6 to 9 inclusive, but in Figs. l to 4 inclusive the interior of the refrigerator body is cylindrical or round, and hence the shelving would necessarily desired, in Figs. 1 to 4 inclusive, each entire shelf can revolve or rotate about a vertical axis, by putting the rollers or Wheels 22 on the sides of the refrigerating chamber, if such is necessary I or desirable. f

It will be seen that the refrigerator body Walls `are thermally insulated, by, suitable linsulation,

compressor fan unit is outside of the reirigerating chamber.

ing chamber therein, with a relatively small subchamber 'extending vertically within said body and thermally insulated from said refrigerating chamber, a cooling unit in the upper portion of vsaid re'frigerating` chamber, and a refrigerant liquefying unit entirely 'enclosed in said sub- -chamber and having a vertical axis of rotation for circulating 'the refrigerating fluid through said cooling lunit and for forcing air upwardly through said sub-'chamber to cool said fluid, said vertical axis of said liquefying unit is not only offset laterally of said refrigerating chambers but is alsoy disposed between the top and bottom planes thereof, thus providing the refrigerator with a laterally offset, rotary compressor unit axis, so that the latter is spaced a distance from the ver- .tical center of said body.

2. A structure as specified in claim 1, said refrigerating chamber being formed cylindrically about a central vertical axis, which latter is parallel with and spaced a distance from said vertical axis of rotation.

3. A structure as specied in claim 1, conrprising removable supporting means enclosed in said refrigerating chamber and rotatable about a vertical axis spaced a distance from said axis of rotation, so that the entire area between the outer edges of said supporting means is avail- .'able for the storage of food.

4.' A structure as specified in claim l, said subchamber having a lateral air outlet above said condenser in the side wall of said body, and a lower air inlet.

i5. A structure as speciedin claim 1, said refrigerating chamber extending under the lower end of said sub-chamber, with a lateral air inlet for the latter in a side wall of said body, and an upper air outlet.

6. A structure as specified in claim 1, said body being round .and having a radial extension on the back thereof for enclosing said sub-chamber.
