l 'lis invention relates to refri rator cabinet construction. f An object of t e invention is to provide an improved form of door opening construction in a' cabinet having heat:

insulatingvwalls and an interior metal lining, whereby no moisture is permitted` to enter into the insulating material adjacent the door opening and cause deterioration thereof and bad odors to escape therefrom and taint the food within the refrigerator.

A more specific. object is to provide a moisture resisting molded bituminous composition facing strip for said door lopenin which overlies the free edge of the metal' l1nin at the door o en'ing and provides a neat looking non-corro g4 moisture proof construction.

.Another object is to provide an elastic sealing gasket, preferably of soft rubber, which -is partially clamped under said facing strip whereby to seal the joint between thefacing strip. and its underlying construction, and which has a projecting portion extending around thedoor-openmg and serving asa bumper gasket` for-'the refrigerator door. 4

Further objects and advantages of the present invention will be apparent from the following descriptiomreference being had to ,the accompanying drawings, wherein a preferred em odiment of one form of thefpresent invention is clearly shown. f In the drawings: f

` 1 is a front elevationl of a refrigera- Fi Ator, ;"cagbinet having heat insulating walls com,-

pletely enclosing the food chamber.

F1 2 is a horizontalsection on line 2-42 of Fig. 1 showing the construction of the vertical sides of the door opening according to this invention. l'

Fig. 3 isa vertical section on line, 3-3' of -Fig. 1 Ashowing the bottom construction of the door opening, which is similar to Fig. 2.

Fig. 4 is an enlargedview looking towardthe lower left corner of the door openin thedoor be' removed, and shows the mp1- tered corner joints of the facing stripand the soft'rubber gaskets.

Similar reference characters referto simillarpartsthroughout the drawings'. 'In the drawings, 10 de l'gnates a wood cor- W ner, post of the cabinet frame and Il a wood door jointxed thereto. 12'is the sheet metal interior lining, preferably covered with enamel or porcelain, having its free -edge 13 at the door .opening partially overlap ing thewood joint 11. 14 is the exterior s eet metal lcasing forming the. exterior wall of the cabinet having its freeedge 15 at the door opening turned in and partially overlaping the joint 11 in opposed relation to the ree edge 13 of the inner lining, as clearly shown in Figs. 1 and 2. These free edges 13 and 15 extendcompletely around the door opening, that is the sectionsliown in Figs-1 and 2 is typical of the top, bottom, and both verticalsides of the door opening. Heat nlining 12 andthe exterior metal strisps 2Q are accurately mitered at the corners as own at 21 in Fig. 4and fixed upon th;

ges 1 `door opening to overlie the metal e and 415 by suitable screwsf-*or nails 22. (see `Figs. 2 and A3). A continuous groove. 24 .is molded in the strip 2O where it overlaps the inner metal lining 12, and va. second continuous groove A25, preferablyv of dove-tail section, is molded therein at its outer edge where it over-laps the outei' metal'casing 14. These grooves 24 and 25 thereforeare continuous laround the entire door opening. *Within groove 24A there is-clamped an elastic gasket 26, preferablyof soft rubber,

absolutely sealed against moisture `entering therein and causing rotting of the cork insu,-

,flation and against odors escapin from the`- heat insulation and entering the oodchamber. Within groove 25 there is clamped the dovetail portion 27 of the soft rubber gasket 30`whi1e the projecting portion 28 of this gasket extends out beyond the exterior casing 114 and forms asuitable bumper gasket yfor vthe door ange 31 and serves to seal the joint whereby thejoint between strip 20 and inner lining 121sv 90 i between the door and the door opening in the cabinet. The ortion 27 0f t e gasket 30 seals the joint between the metal edge of the outer casing and the facing strip and so completely seals up the heat insulation space which includes the wood members 10 and 11. IThis sealing by gasket portion 27 is advantageous since moisture may'pass to or odors may esca e from the heat insulation material throug the porous wood members or the joints and Cracks therein. The facing strip 20 being molded from a. moisture-resisting non-porous composition of bituminous material itself serves as a seal over the ing gaskets interposed between each of said' signature.

other similar hard asphalt of melting point about 300 F., 22 arts of Trinidad asphalt of melting int a out 200 F., 17 parts of lacerated as estos fiber, and 17 parts of an inert filler such as infusorial earth. The bituminous materials are lirst melted'and then thoroughly mixed together with the asbestos fiber and filler in. a suitable kneading machine to form a hot plastic mass. This plastic material is then put in suitable unheated molds and molded under high hydraulic and a sufficient seal obtained by 1 pressure for only several minutes, after which the molded strips are removed from the molds and allowed to cool. material is especially well adapted for form-A ing these facing strips 20 for refrigerator ca inets since it can be easily and economically molded to the desired section of the strip, since it is moisture proof and therefore completely seals off the space containing the heat insulation material, since it is non-corrodible and may be coated with asuitable finishing material, and since it may be as etasily mailed or screwed in place as a wood s rip.

While the form of embodiment of the present invention as herein disclosed, constitutes a referred form, it is to be understood that o er forms might be adopted, all coming within the sco of the claims which follow.

What is claimed is as follows:
