REFRIGERATOR-DOOR.

Specification of Letters Patent.

Application filed August 2, 1920. Serial No. 400,704.

To all whom 'it may concern:

Be it known that I, GEORGE I-I. Rien, a citizen of the United States, residing at Arlington, county of Bennington, State of Vermont, have invented certain new and usciul Improvements in Refrigerator-Doors, of which the following is a specification.

The object of my invention is to provide a door for refrigerators of simple, economical construction and one which will thoroughly insulate the ice and food chambers, preventing cold air from escaping and warm air from entering the chambers.

A further and particular object is to pro`- vide improved means for mounting an insulating lining on the frame of the door to the end thatk the door may be air-tight under all conditions and at the same time present a neat, finished appearance when open.

Other objects of the invention will appear from the following detailed descrip tion.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure l is a perspective view of a refrigerator door embodying my invention,

Fig. 2 is an inside view of the door before the lining is mounted therein,

Fig. 3 is a sectional view on the line 3-3 of F ig. 2, I

Fig. a is a view corresponding to Fig: 3, showing the manner of mounting the lining on the door frame.

In the drawing, 2 represents the frame of the door, of ordinary construction. The inner face of the frame is rabbeted at 3 forming a raised portion or shoulder 4;. 5 represents a series of wooden strips secured by nails 6 or other suitable means to the iframe. The strips are spaced apart to form gaps 7 and also have grooved opposing edges 8, as shown plainly in Fig. 3. The outer strips have longitudinal edges 9 which overlap the inner portions of the rabbets 3 forming an overhang extending around the door. l0 is an insulating sheet consisting of a composition material containing asbestos, which is molded on the door frame in plastic form to conceal the strips 5 and has lips l1 which extend in under the edges 9 to form locks for securing the asbestos sheet firmly to the door. When this plastic material hardens, it will form a smooth continuous surface completely vconcealing the strips 5. The` plastic material is forced into the gaps and into the grooves 8 forming ribs l2 which aid in locking the sheet to the wooden strips. I also prefer to place a sheet `of building` or other noneheat conducting material 13 between the frame and the strips 5. This sheet 13 also closes the inner openings of the gaps between the strips so that the plastic material is prevented from liowing entirely through these openings.

This invention may be applied to doors of different sizes and may be used in other ways where it is desirable to fasten an insulating lining to a door frame 'or other support.

I claim as my invention:

l. The combination, with a frame having a panel opening therein and a rabbet encircling said jopening, of a panel mounted on said frame and having its longitudinal and transverse edges projecting beyond the shoulder of said rabbet, whereby an inwardly extending groove is formed around said panel opening, and a sheet of insulating material applied in plastic form to said panel and locked thereon by flowing into and filling said groove.

2. In combination, a an inner rabbeted face, plates secured to said face and having edges lapping said rabbets to form a recess around the edge of the door frame, and a sheet of insulating material applied in plastic form to said plate and iiowing into said recess to lock, when set, the plastic material and plate together.

3. In combination, a refrigerator door door frame having frame andplates secured thereto, said frame having a recess around the outer edge and gaps between said plates and an insulating material coveringand concealing said plates and applied in plastic form thereto to enter the gaps between said plates and the recess around the edge of said frame.

4t. The combination, with a frame having a panel opening and a rabbet extending around said opening, of a plate like closure for said panel opening, the peripheral portion of said closure projecting beyond the shoulder formed by the rabbet of said frame, a recess being thereby formed extending around said panel opening and said closure being composed of strips having longi- Patcnted July i9, 192i.,

l tudinal gaps between ying material applied to insulating material applied to the inner face of said closure in plastic into said longitudinal gaps and around the peripheral portion of said closure and into the recess encircling said opening, whereby said insulating rsheet when set is .locked on said closure. y Y

5. The combination, with a Jframe having a` panel opening therein and a rabbet in one face Vthereofv encircling` saidopening, of a panel composed of strips seated upon said rabbeted face and means for securing said strips0 to said frame, said strips projecting beyond the shoulder of said rabbet whereby to form therewith a groove extending around the panel opening, said stripszbeing spaced Vapart to provide gaps between adja# cent longitudinal edges, said last named edges being grooved, and a sheet of insulatthe inner :tace of said strips in plastic form and molded around the edges of said strips and into said groove and gaps,` whereby when said plastic material is set, said sheet will besecurely locked onsaid Jframe and no securing means will be visible.

6. A door comprising arframe having a y panel opening therein and a panel secured them, and a sheet of Y form and flowing n to said frame over said opening, a groove being formedy around said panel opening and a sheet of insulating material applied in plastic form to said panel and locked thereto and to said frame by flowing into and becoming set in said groove.

7. A door comprising a frame having a panel opening therein and a panel secured to said-frame over said opening and provided with a series of gaps therein, a groove being formed around said panel opening and a sheet of insulatingmaterial applied in plastic form to said panel and locked thereto and to said frame by flowing into and becoming set in said groove and said gaps. v

8. A refrigerator 4door comprising a frame having a panel opening therein and a 'panel secured to said frame over said opening,.said door having Van inwardly extending groove encircling said panel `opening anda sheet of insulating material applied in plastic form to said panel and locked thereon by flowing into and becoming set in said groove.

In witness whereof, I have hereunto set my hand this 27 th day of July 1920.
