l Claim.

The present invention relates to new and useful improvements in electric refrigerating devices and has forits primary object to provide an apparatus of this character which is installed in a portable container of relatively small size so that the refrigerator may be carried in an automobile and connected to the electric system of the automobile for operating the refrigerator, or the refrigerator may be used in the home and operatively connected with the house circuit.

An important object of the present invention is to provide an electrical refrigerator of simple and compact form, which is neat and attractive in appearance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction as ,more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout and in which:

Figure 1 is a iront elevational view.

Figure 2 is a top plan view.

Figure 3 is a sectional view taken substantially on la line 3 3 of Figure 2.

Figure 4 is an end elevational view of the motor compartment.

Figure 5 is a sectional view taken substantially -on a line 5 5 of Figure l and Figure 6 is a transverse sectional view of the food or storage compartment.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates the refrigerator housing of substantially box-like form, the housing being of a double wall construction including spaced inner and outer walls 8 and 1 having the insulation material 8 positioned between the walls. The housing 5 includes the food or storage compartment 9 which is of substantially rectangular form and preferably of square-shape in cross section and within which. the freezing coil unit l0 of conventional construction is mounted.

To one end of the housing is secured an extension ll forming the motor compartment l2, the end of the compartment i 2 being closed by a screen i3 to admit air into the compartment for cooling the electric motor Il, compressor I 5 as well as the other conventional electric re frigerating mechanism and also for supplying air to the condenser IB, all of which are mounted in the compartment I2 as shown to advantage in Figures 3 and 5 of the drawings. An extension cord i1 is connected to the electrical equipment oi the mechanical refrigerating unit having the connection plug I8 attached thereto for connecting to a suitable outlet of an automobile electrical system, or toa house current, it being understood that a suitable transformer is provided in the electrical equipment to provide for the difference in voltage. The front wall of the housing 5 is preferably provided with a pair of doors i9 and 20 hingedly connected at one edge as shown at 2l, each of the doors having the conventional catch devices 22 for securing the doors in a closed position. The doors provide convenient access to all portions of the interior of the com- Dartment 9.

At the end of the housing 5, as well as the end of the extension li are provided handles 23 by means of which the refrigerator may be conveniently transported to the desired place. The handle at the end oi the extension is attached to a cross bar 24 extending across the end of the extension outwardly of the sceen.

From the foregoing it will be appreciated that the refrigerator is constructed of compact form and of a reduced size adapted to be conveniently carried in an automobile, when desired.

It is believed the details of construction, advantages and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

What is claimed is:

A. refrigerator comprising a rectangular shaped case having insulated walls forming a storage compartment. one oi' said walls having a closure providing access to the compartment and said compartment having a refrigeration freezing unit therein, an extension on one end of the case forming a compartment adapted to contain a mechanical refrigerating unit including an electrically operated motor, the top. bottom. front and rear walls of the extension being substan- 7 tially in the plane of the corresponding walls of the case, and the outer end wall of the extension being open, a foraminous cover for said outer end wall oi the extension to admit air to the interior thereof, a rigid bar transversely at the outer end of the extension, a handle secured to the bar, and a second handle at a relative opposite end of the case.
