REFRIGERATOR Original Filed Nov. 8, 1930 K INVENTOR 5/30 Mariam ATT NEY Patented Oct. 24, 1933 UNITED STATES PATENT OFFICE REFRIGERATOR Application November 8, 1930, Serial No. 494,357

Renewed April 15, 1933 2 Claims.

This invention relates to refrigerators, and particularly to the construction thereof. More especially, this invention relates to the disposition of a gasket on a refrigerator door and the assembly of said door with said gasket.

In the drawing:

Figure 1 is a front view of a refrigerator with the door open;

Figure 2 is a detail view of a portion of the re- 1o frigerator door with parts broken away; and

Figure 3 is a section on line 3-3 of Figure 2.

The refrigerator comprises a cabinet 1 having a top 2, beneath which may be disposed automatic refrigerating mechanism of any well-known type. The box is provided with a plurality of legs 3. A cold control 4 is provided in front of the box. Beneath the cold control there is a door opening 5 giving access to the interior of the refrigerator. The jambs of door opening 5 preferably comprise strips 10 of suitable rigid heat insulating material, disposed to form an inwardly tapering frame.

Co-operating with the jambs is a door 20. The door preferably comprises 'an outer metallic sheath 21 having a rounded edge 22 provided with a parallel inturned portion 23 and terminating in an angularly disposed mounting flange 24. An inner metal sheath 31 is provided with an angularly disposed mounting flange 34. Disposed within the space enclosed by inner and outer sheaths 21 and 31 is suitable heat insulating material 40. In order to support inner sheath 31 on outer sheath 21 in "predetermined spaced relationship, rigid strips 41 are provided and are bolted to flanges 24 and 34, respectively. At the corners, angle irons 42 may be provided to give a smooth edge and form a rectangular door frame.

Prior to the bolting of strips 41 to flange 24, a

gasket 45 of any suitable material and shape, and

and strip 41. Bolts 50 may then be disposed in suitable registering apertures in strips 41 and flange 24.

By mounting the gasket in this manner, not only is an invisible and firm mounting for the gasket secured, but the expense incident to separately fastening the gasket to the door is completely eliminated.

I claim:

1. In a refrigerator cabinet, a door comprising an outer metal panel having inturned edges, said edges being so shaped that a peripheral flange adapted to abut against the front border of the door opening of the cabinet is formed, an inner metal panel having its edges bent, rigid heat insulating strips secured to the edges of said two panels and maintaining said panels in spaced relationship, and a gasket having a sealing portion disposed along said peripheral flange, said gasket extending to said heat insulating strips and being maintained in place by the same fastening means which maintain the outer panels and strips together.

2. In a refrigerator cabinet, a door comprising an outer metal panel having inturned edges, said edges being turned in in such manner that a pcripheral flange adapted to abut against the border of the door opening in the cabinet is formed, an inner metal panel, rigid heat insulating strips formed as a frame and disposed between the edges of said two panels, means for fastening the edges of said inner panels and frame together, means for fastening the edges of said outer panel and frame together so that said panels are maintained in spaced relationship, and a gasket having a sealing portion lying against said peripheral flange, said gasket having an edge disposed between the edges of said outer panel and insulating frame and maintained in position by fastenings between said frame and outer panel.
