My invention relates to refrigeration, and particularly to providing sealing means for the joints between the cabinet and the doors affording access to the compartments thereof, and the principal object of my invention is to provide new and improved means of this type. In the drawings accompanying this specification and forming a partof this application I have shown, for purposes of illustration, one form which my invention may assume, and in these drawings:

Figure 1 is a. front elevation of a refrigerator cabinet embodying my invention, while Figure 2 is a section on the line 22 of Figure 1.

The embodiment of my invention shown herein comprises a refrigerator cabinet 11 having

compartments

12 and 13 provided with openings 14 and 15 affording access thereto,

doors

16 and 17 for closing said openings, and sealing means 18 for sealing the joints between the walls of the openings 14: and 15 and the

doors

16 and 17 The sealing means comprises a strip of spring metal 18 having one edge 20 attached to the wall of the cabinet 11 about each of the openings 14: and 15 by nails 21 or similar means and having an angularly bent resilient free edge 22 disposed in a groove 28, surrounding each of the openings 14 and 15, and a V-shaped bead 24 secured to each of the doors adjacent its periphery. hen the doors l6 and 17 are closed the beads 24 cooperate with the resilient free edge of the spring metal strip 18 to form a practically airtight seal between the wall of the cabinet 11 and the

cabinet doors

16 and 17.

From the above disclosure it will be obvious to those skilled in the art that I have provided new and improved sealing means for the joints between the cabinet and the doors affording access to the compartments against passage of air.

I claim:

1. The combination with a cabinet pro vided with an opening through the wall of Serial No. 169,756.

said cabinet to permitaccess to the interior thereof, said wall having a groove adjacent the opening therethrough and a door for closing the opening in said cabinet, said door being adapted to close the groove when the opening is closed; of sealing means comprising a resilient strip of metal secured to the edges of said cabinet adjacent the opening therethrough and extending into said groove. and a rubber bead secured to the edge of said door to contact with said strip within said groove when said door is closed.

2. The combination with a cabinet provided with an opening through the wall of said cabinet to permit access to the interior thereof, said wall having a groove therein surrounding the opening and a door for closing the opening in said cabinet wall; of sealing means comprising a continuous resilient metallic strip having one edge fixed to said wall the free edge projecting into the groove in said wall, and an endless rubber bead secured to said door, said bead being adapted to enter the groove in said wall and contact with the free edge of said strip when said door is in closed posit-ion.

3. The combination with a refrigerator cabinet provided with an opening through the wall of said cabinet, said wall having a groove therein adjacent the edge of the opening therethrough, and a door for closing the opening in said cabinet; of means for sealing the joint between the wall adjacent the opening in said cabinet and said door, said means comprising a strip of resilient metal secured to the wall of said cabinet and projecting into the groove in the wall of said cabinet, and a bead of resilient compressible material adapted to cont-act with said strip at an acute angle thereto.

4. The combination with a refrigerator cabinet provided with an opening through the wall of said cabinet to permit access to the interior thereof, said wall having a groove formed therein adjacent the edge of the opening therethrough and a door for closing the opening in said cabinet; of means for sealing the oint between the wall adjacent the opening in said cabinet and said door, said means comprising a single metallic strip secured along one edge to the wall adjacent the groove the free edge of said strip being bent into the groove, and a bead of resilient nonmetallic material substantially triangular in cross section secured to the inner surface of said door to contact with the portion of said strip extending into the groove.

5. In a refrigerated food storage cabinet, a Wall having an opening therethrough, said Wall having a groove in the exterior surface adjacent to and surrounding the opening, a door adapted to cover the opening and the groove in said Wail, resilient means projecting into the groove in said Wall, means secured to said door adapted to extend into the groove and cooperating With said resilient means to form a continuous sealed joint between said door and said Wall when said door is closed.

In testimony whereof I hereunto affix my signature.
