Application filed. March 29, 1915.

To all 'wom t may concern.'

Be it known that l", CHARLES A. Karrieren, a citizen of the United States, and resident of .East St. Louis, Illinois, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

J.y invention relates to improvements in refrigerators, of the type shown and described in Patent No. 1,181,772 granted to me May 2, 1916, wherein a container for cracked ice and salt is provided with vertically disposed flues exposed to the ice and salt and through which air is passed, cooled and directed into the refrigerator body.

The object of the improvements in this application is to construct the air ilues 'of sections of different diameters and varying lengths in order that the overflow points will be at different levels in the various flues whereby to provide for overflow from the salt and ice through each flue regardless of the level of the refrigerator, as a whole.

With the above object in view, my improvements consist in certain novel features of the construction and arrangement of parts which I will fully describe, specifically point out in my claims and illustrate in the accompanying drawings, in which:

Figure 1 is a longitudinal sectional elevation of a refrigerator embodying my improvements F ig. 2 is a sectional plan taken on the line 2*@ of Fig. l;

Fig. 3 is an enlarged plan of the uppermost section of one of the flues showing the screen for the upper, open end thereof; and

Fig. 4 is a fragmental, vertical sectional elevation of the flue showing the screen.

Referring by numerals to the accompanying drawings:

5 designates the refrigerator body, the side walls 6 of which may be of any approved, insulated construction, and which has at its rear the hinged doors 7 and at its top the hinged door 8, the former providing access to the refrigerator body for purposes of cleaning and repair, and the latter providing access to the ice container.

Extending from the refrigerator are one or more display cases 9 whose interiors are direct communication. with the refrigere Speceation of Letters Patent.

Patented Apr. 17, 1917.. Serial No. 17,749.

ator and whose walls are of any approved insulated construction and preferably glazed, so that wares may be displayed therein.

lThe ice and salt container which is placed in the refrige 1ator comprises a lower section 10 which, as shown, is rectangular in plan, and of hopper shape. At each corner there is a. support in the foi-in of an angle iron 11, and to which the section 10 is secured.

The inclined lower walls of this section 10 are each perforated at intervals and in each perforation there is inserted a tube 11 which are cach flanged at their lower ends for securing about said perforations. These tubes 11 are of varying heights, are preferably made of corrugated sheet metal, and each tube has adjacent its upper end a transverse rod 12. Slipped into each tube 11 and supported on the rod l2 is a tube 13, of plain f sheet metal, and like the tubes l1 the tubes 13 are of varying heights, and have at their upper ends the transverse rods la.

Slipped into thev upper ends of the tubes 13 are the tubes 15 which rest upon the rods lei and are of varying heights with their upper ends in substantially the same plane. rThese tubes 15 are made of corrugated sheet material and each has at its upper end a crimp 1G which constitutes a support for a screen 17, designed primarily to prevent ice from falling through the tubes when being supplied to the container, and which screen prefer to make of a single strip of sheet metal in the form of a spiral.

The upper section 18 of the ice container is of rectangular form in plan and is secured to the supports 11, with its lower end overlapping the upper end of the lower section and spaced therefrom by said supports.

This upper section extends to substantially the level of the upper ends of the uppermost tubes, and which is by preference the full height of the refrigerator body, except such spacing as is required to furnish air to the tubes from the top of the refrigerator. Over the top of the container there is a cover 19, having openings 2O registering with the tubes. This cover is designed to form with the body of the container a complete closure for the ice and salt in order to minimize moisture in the refrigerator as well as to conserve ice.

At the bottom of thecontainer l provide a drain cock, which is by preference kept open when the refrigerator is iced-and in use.

In arranging the walls of the container of overlapping and laterally spaced wall sections it is apparent that brine from the salt and ice will flow between the spaced walls, down the exterior wall of the lower section and remove any accumulated frost and prevent further accumulation of frost so long as the level of ice and salt is above said spaced wall portions.

All the tubes are made of the laterally spaced sections for the same reason as given for the container walls and I find that air inf passing downwardly through clean tubes uninsulated with heavy coats of frost will Vmore nearly become the temperature of the ice and salt, than when passed over or between surfaces which are laden with accumulated frost.

The construction of the tubes shown, z'. e., of alternate plain and corrugated cylinders I consider one inexpensive and practicable way of providing openings at intervals into the ice and salt container, but do not wish to be considered as limiting myself to this one form, as many modifications suggest themselves to me, and will be obvious to others skilled in the art.

Copies of this patent may be obtained for five cents that claim as new and desire to secure by Letters Patent of the United States is:

1 In combination with a salt and ice container, a plurality of open ended tubes extending through said container, each of said tubes being constructed of telescoping sections and certain of said sections being constructed of plain material and the remaining sections constructed of corrugated material, whereby to provide for the iiow of brine from the salt andicecontainer over the interior faces of said tubes.

2. In combination with a salt and ice container, a plurality of open ended tubes eX- tended through the said container, each tube being constructed of alternate plain and corrugated telescoping sections, the said sec- Y tions varying in lengths in the several tubes to provide for the flow of brine from the container at different elevations into, and over the interior surfaces of said tubes.

ln testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

CHARLES A. KETTERER.
