July l'l, @34 E. B. NEWILL REFRIGERATING APPARATUS Original Filed July 30. 1931 INVENTOR M Hfsl ATToRN/Evs.

Patented July 17, 1934 UNITED STATES PATENT OFFICE REFBIGERATING APPARATUS ration of Delaware Application July 30, 1931, Serial No. 554,05R Renewed November 8, 1933 5 Claims.

My invention relates to insulated cabinets generally and specifically to the door opening and door constructions thereof.

The objects of my invention are to provide an 5 improved cabinet construction and more particularly to provide an improved means for sealing the door opening when the door is closed and for breaking the metallic contact between the interior and exterior of the cabinet.

l Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing wherein a preferred form of the present invention is clearly shown.

l In the drawing:

Fig. 1 is a View in elevation of a refrigerator cabinet embodying features of this invention;

Fig. 2 is a view in elevation of the door structure as viewed from the interior of the cabinet;

23 Fig.- 3 is a view in section taken on the line 3 3 of Fig. 2, and

Fig. 4 is a view in section taken on the line 4 4 of Fig. l.

Specifically my objects are attained by providing a flexible rubber gasket seal adapted to partly telescope the inner lining or a member equivalent to the inner lining of the cabinet, the seal having a flexible and resilient portion adapted to bear against the exterior surface of the 39 cabinet when the door is closed.

Referring to the drawing, I have shown a refrigerator cabinet embodying features of my invention, the cabinet being generally designated by the reference character 10 and being shown as provided with a refrigerated food storage compartment 11 closed by the door 12 and with a machinery compartment 13 closed by the door 14. In actual use of such a cabinet, an evaporator is generally provided within the food storage compartment 11 and this evaporator is connected to a liquefying unit, either of the absorption or compression type located within the machinery compartment 13.

The cabinet shown partly in section in Fig. 4

includes an inner metal lining 16, an outer metal lining 17, both linings having their ends secured to the cabinet frame 18 by means of an insulated strip 19, which strip is secured to the frame 18 by means of screws, not shown.

Insulating material 20 is of course provided between the inner and outer linings and to prevent injury to the lining 17, chip board 23 is positioned between the insulating material 20 and the outer lining 17.

0 It should be understood that this cabinet con- (Cl. 2li-35) struction is for illustrative purposes only, it being essential only to provide some means for breaking the metallic Contact between the 1inings 16 and 17 equivalent to the insulating strip 19 shown in Fig. 4.

The door construction is shown as including the usual frame member 30 carrying the inner metal lining 31 and the outer metal lining 32, there being insulating material 33 located between the linings 31 and 32.

In operation, it is essential to seal the door opening when the door is closed and at the same time to break the metallic contact between the inner lining 31 and the outer lining 32.

It is to this means that my invention particularly relates and to illustrate rny invention, one specific form of sealing an insulating means is shown in Figs. 2, 3 and 4. For example, a exible resilient gasket member 40 is formed with a cylindrical portion 41 and with two substantially parallel laterally extending portions 42 and 43. In the particular modification shown, this gasket has its lower laterally extending portion 42 secured to the frame member 30 between the ends of the liners 31 and 32 by means of a metal strip 46 secured .to the frame 30 by means of tacks or screws 47. The upper laterally extending portion 43 has its end over-lapping the end of the inner lining 31. In this manner the metal retaining strip 46 and screws or tacks 47 are hidden from view, the gasket 40 thereby not only breaking the contact between the lining 31 and the lining 32 but also presenting a pleasing finish to the door construction. The cylindrical portion 41 of the gasket extends rearwardly from the outer lining 32 and when the door is closed is deformed to provide a very efficient seal as shown in Fig. 4.

It should be understood that the gasket 40 extends entirely around the door as shown in Fig. 2 and is retained in place by means of the retainer strip 46 also extending substantially around the door. the retaining strip 46 in eiect is a continuation of the inner metal lining 31 and, if desired, the lining 31 may be continued substantially to the left and end of the retaining strip 46 to thereby entirely eliminate the use of such strip. In other words, the laterally extending portions 42 and 43 of the gasket 40 may overlap the end of the inner lining 31 within the scope of my invention. In this latter case the results produced and the function of the gasket 40 are substantially the same as when the retaining strip 46 is used.

It should also be noted that While the form of embodiment of the invention as herein disclosed constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:

l. In combination with a cabinet provided with a door opening, a door construction including an inner metal lining, an outer metal lining and insulating material between. said linings, a gasket seal between the adjacent ends of said linings, said gasket seal including a sealing portion and laterally extending portions, a retaining strip between said laterally extending portions, fastening members extending through said retaining strip and one of said laterally extending portions into the door construction for securing said gasket to said door construction.

2. In combination with a cabinet provided with a door opening, a door construction having an inner metal lining with a curled edge, an outer metal liningA with a curled edge, a gasket seal between the ends of said linings having portions overlapping the curled edges of the metal linings, said overlapping portions being formed to fit the curled edges, said gasket seal having a kerf therein, a metal reinforcing strip lodged within the kerf, and fastening members extending through the metal reinforcing strip for securing the gasket to the door construction.

3. A door construction including a structure having a sealing means, said sealing means including a gasket seal having a sealing portion and two parallel lip portions extending laterally from the sealing portion, a retaining member between the laterally extending lip portions, said retaining member securing and clamping one of the laterally extending lip portions to the structure at a point spaced laterally from and out of alignment with the point of engagement of the sealing portion of the gasket with a member adapted to be sealed thereby to hold the gasket seal in place.

4. A door construction including a structure having a sealing means, said sealing means including a gasket seal having a sealing portion and two parallel lip portions extending laterally from the sealing portion, a retaining member between the laterally extending lip portions, and fastening means extending through the retaining member and one of the laterally extending lip portions at a point spaced laterally from and out of alignment with the point of engagement of the sealing portion of the gasket seal with a member adapted to be sealed thereby for fastening the gasket seal to the structure.

5. A gasket seal of a yielding material having a cylindrical sealing portion and a portion extending therefrom provided With a kerf forming two parallel laterally extending lip portions, one of said parallel laterally extending lip portions serving as a means for fastening the gasket seal out of alignment with the cylindrical sealing portion thereof.
