UNITED STATES-PATENT OFFICE PORTABLE COOLER Harry Clemens Salsrnann, Chicagmlll.

Application October 28, 1946, Serial No. 706,260

This invention relates to a new article of manufacture having the characteristics of a footrest, ottoman, hassock, or the like, and a refriglerator unit or cooler all ccntained in a unitary structure.

The main objects of thisinvention are to provide a device of this character having the characteristios of a footrest, hassock or ottoman, or the like, and a refrigerator unit or cooler, all arranged in a simple, compact unitary structure; to provide a device of this character wherein the temperature within the interior thereof is controlled and held uniform; to provide a structure of this character which is readily portable; to provide a structure of this character wherein Dry Ice preferably constructed of sheet metal rigidly or ice cubes may be utilized and disposed within v housings placed about the interior of the unit; to

provide a device of this character which will bek attractiveY in appearance and economical to use; and to provide a, device of this character which is simple in construction and inexpensive to manufacture.

An illustrative embodiment of this invention is shown in the accompanying drawings in which:

Figure 1 is a perspective View of my device.

Figs. 2 and 3 are cross sectional Views taken on the lines 2-2 and 3-3 of Figs. 1 and 2, respectively.

Fig. 4 is a perspective View of the door of my invention, with parts shown broken away and in cross section.

The outer structure of my device is an upholstered ottoman, footrest, hassock or like device commonly used in most homes. The device disclosed in the drawings for illustrative purposes is an upholstered hassock having a top I,

Vertical side walls 2, all suitably upholstered and nished to present a pleasing appearance to the eye. It will be appreciated that a suitable cushion may be placed on top I if desired. The side walls 2 are all secured in the usual manner to suitable skeletal framework 5 consisting of uprights and cross bars.

An inner liner preferably constructed of sheet steel, or the like, is secured to and within the interior area of the framework 5 as clearly shown in Figs. 2 and 3, and comprises a top- S, side walls 1, a back wall 8, all generally conforming to the shape of the side walls 2 of the exterior of the device, and a. bottom wall 9, all integrally secured together at their marginal edges to form a chamber to receive articles to be stored therein.

.The ice receptacle comprises a pair of elongated vertically disposed tubes I6 and II, substantially square in cross section (see Fig. 3

mounted on the rear wall 8 of the inner liner and spaced apart as rshown in Fig. 3. The upper ends of the tubes II). and II extend through the top wall 6 of the inner liner and into the area constituting an upper chamber dened by the top wall 6 ofthe inner liner and the top I of the device. Each tube is provided with a hinged cover plate I2 and access thereto is had by removing the top I or if the tcp I is hingedly secured, as shown in Fig` 2 by the hinge I3, then by raising the top I by lifting the same upwardly at its front edge as indicated by the dotted lines in Fig. 2 the saine result is obtained.

In order to insure that the chamber formed by the inner liner retains its low temperatures after it has been cooled by the ice Iii, in the form of cubes, crushedrice or Dry Ice, I pack insulation material I5v in the spaces defined by the framework 5, side walls 2 and the liner walls 'I and 9, as shown in Figs. 2 and 3. I provide a door I6 in the front of the device which is hingedly secured as at II to one of the side walls 2, whereby to provide access to the chamber formed by the inner liner. A pair of ice containers, in the form of elongated tubes I -I similar in substantially all details to the tubes IEJ-I I, are rigidly secured to the inside face of the door I6, one adjacent each side edge thereof and each is provided with a cover plate 20 whereby access to the interior of the tubes is had.

The ice tubes IIJ-II are provided with a connecting tube 2l positioned at the lower ends of the tubes IIl--II whereby any water or moisture accumulating in the tubes may be concentrated and drawn off through the pet cock or valve 22. A similar tube 23 and valve 24 is provided for the ice tubes I8-I9 to perform the same function.

The device of my invention may also contain a utility drawer 25 positioned, as shown in Figs. l and 2, and disposed between the top I and top wall 6 of the inner liner.

It will know be apparent that this device may be used anywhere in the home and is particularly useful in parts of the home remote from the usual icebox, and Will keep cool or chill bottled beverages, for instance, when the tubes III-II and IS-IS are lled with ice cubes or Dry Ice, and thereby provide a convenient small portable cooler.

Since there is always a possibility that condensation is likely to form on the inner side Walls of the inner liner, I iind it advisable to place a drip pan 26 on the lower wall 9 of the inner liner an inner liner positioned Within the interior area4 of said framework, a plurality of elongated'ice';

tubes vertically disposed within the inner area of and mounted on said inner liner'and' on said4 door, and insulating meanssdisposed ini` the:

spaces defined by said framework, the side and back walls of said inner liner, and said side-walls*` 2. In a device of theclass described a framework having fully upholsteredfside Wallszandtop, a door hingedly secured to said` framework, an inner liner positioned within the interior' area of said framework, a plurality'of. elongated ice tubes vertically disposed within theinner area of and mounted on said'inner liner andony said door, means placing the. tubes securedl to said inner liner in communication;withone another, means placing the tubes securedltovsaid' doorin communication with one another, and-insulating means disposedi in the spaces` defined' by said framework the side andiback Walls-'ofsaidinner liner, and said side walls.

3. In a device of the class desc/ribedaframework having fully upholsteredfside walls and-top,

a door hingedly securedv to said framework, an' inner liner positioned Within the-interior area of said framework, a plurality* of elongated' ice tubes vertically disposed within-1 the* inner area of and mounted on said inner liner and on said door, means placing the tubes secured to said inner liner in communication with one another, means placing the tubes secured to said door in communication with one another, an outlet port in one of said tubes secured to said inner liner, a second outlet port in one of said tubes on said door, and insulating means disposed in the spaces defined by said framework the side and back walls of s'aidinn'er liner, andsaid side walls.-`

4. In a device of the class described' a framework having fully upholstered side walls and top, a door hingedly secured to said framework, an inner liner positioned within the interior area of said framework, a plurality of elongated tubes disposed' vertically within the inner area of and mounted on said inner liner and a plurality of vertically disposed elongated ice tubes positioned on the interior face of said door, means placing the tubes secured to said inner liner in communication with one another, meansplacing the tubes secured tosaidvdoor in communication with one another.; an outlet port'inone of` said tubessecured to said inner liner, a second outlet port in one of said tubes on said door, a drip pan posi-- tioned in the lower portion ofi said inner liner, and: insulating means disposed inv the spaces dened by said framework the side and back walls. of said inner liner, and said-side Walls.
