Abstract
Abstract An oven door construction in which the door is adapted to be sealed to a front plane surface when the door is closed. The seal comprises tubular elastomeric gaskets having metal inserts in their ends removably secured to the front plane surface around the oven opening. The inserts are held in place by room temperature vulcanizing adhesive and have structures cooperating with holes in the front plane surface into which the structures are engaged. The gaskets are stretched to make them fit and held in place by tension, while being easily removable to enable the oven front plane surface to be cleaned or the gaskets to be replaced.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
235 words
In an oven construction including a door and a frame having confronting surfaces, means for sealing the door when closed against the surface of the frame, said means comprising an elongate gasket member of extensile elastomeric material which is stable at the temperatures of operation of the oven, at least the end portions of the gasket member having hollow internal bores, a pair of metal inserts respectively engaged within said bores, each insert comprising a body portion which is relatively short compared with the overall length of the gasket member and the body portions being engaged in the respective bores, elastomeric connecting means between said body portions and the interior walls of said elongate gasket member at said bores, the connecting means being formed by an adhesive of a type which is capable of adhering to the metal of the inserts and the surface of the gasket member in a strong bond not adversely affected by the temperatures of operation of the oven, said inserts each having mounting parts integral with the respective body portions exposed at the ends of the gasket member, and means for removably securing the gasket member by means of such mounting parts to one of the confronting surfaces respectively at points thereon spaced apart a distance greater than the normal separation of the mounting parts, the gasket being stretched in such mounting and held under tension against said one surface.
Claim 2
Dependent Claim
235 words

Claim 3
Dependent Claim
29 words
The construction as claimed in claim 1 in which the mounting parts comprise hook formations and the means for securing the gasket member comprise perforations in said one surface.
Claim 4
Dependent Claim
15 words
The construction as claimed in claim 1 in which the adhesive comprises an RTV adhesive.
Claim 5
Dependent Claim
29 words
The construction as claimed in claim 1 in which said body portions have barbs formed therein to resist pulling said body portions out of the bores of said gasket.
Claim 6
Dependent Claim
33 words
The construction as claimed in claim 1 in which said body portions have passageway means through the same and the connecting means includes at least one adhesive connection extending through said passageway means.
Claim 7
Dependent Claim
40 words
The construction as claimed in claim 2 in which the body portions comprise generally flat strips of uniform width substantially the same width as the inner diameter of said bores and said hook formations are substantially narrower than said width.
Claim 8
Dependent Claim
23 words
The construction as claimed in claim 5 in which said passageway means comprise a plurality of punched out passageways in said body portions.
Claim 9
Dependent Claim
119 words
A gasket for use in connection to an oven for sealing the door and frame of the oven when the door is engaged to the frame face to face, said gasket comprising an elongate hollow elastomeric extruded member with the ends providing sockets, a pair of relatively short inserts formed from flat strips of metal and each having a generally rectangular body, a hook formation at one end thereof and a plain opposite end, the rectangular body of each being engaged in the socket at one end of the gasket with the hook formation protruding therefrom and there being a bond of cured RTV adhesive interconnecting the body of each insert with the socket in which it is engaged.
Claim 10
Dependent Claim
119 words
A gasket for use in connection to an oven for sealing the door and frame of the oven when the door is engaged to the frame face to face, said gasket comprising an elongate hollow elastomeric extruded member with the ends providing sockets, a pair of relatively short inserts formed from flat strips of metal and each having a generally rectangular body, a hook formation at one end thereof and a plain opposite end, the rectangular body of each being engaged in the socket at one end of the gasket with the hook formation protruding therefrom and there being a bond of cured RTV adhesive interconnecting the body of each insert with the socket in which it is engaged.
Claim 11
Dependent Claim
24 words
The gasket as claimed in claim 8 in which there are passageways transversely through said body and said bond also extends through said passageways.
