Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
105 words
Apparatus for elastically attaching an exhaust manifold to the cylinder head of a motor comprising: upper and lower, inclined supporting surfaces provided on said exhaust manifold and said cylinder head wherein said inclined supporting surfaces are in facing relationship and said surfaces of both said manifold and head are defined within transversely disposed planes, and elastic means disposed between either said upper or lower inclined supporting surfaces provided on said exhaust manifold and said cylinder head for pressing said exhaust manifold against its gasketed mating surface with said cylinder head and wedging said other exhaust manifold surfaces into contact against said other cylinder head surfaces.
Claim 2
Dependent Claim
105 words
Apparatus for elastically attaching an exhaust manifold to the cylinder head of a motor comprising: upper and lower, inclined supporting surfaces provided on said exhaust manifold and said cylinder head wherein said inclined supporting surfaces are in facing relationship and said surfaces of both said manifold and head are defined within transversely disposed planes, and elastic means disposed between either said upper or lower inclined supporting surfaces provided on said exhaust manifold and said cylinder head for pressing said exhaust manifold against its gasketed mating surface with said cylinder head and wedging said other exhaust manifold surfaces into contact against said other cylinder head surfaces.
Claim 3
Dependent Claim
32 words
Apparatus for the elastic attachment of the exhaust manifold as set forth in claim 1 wherein said inclined supporting surfaces are machined into retaining flanges of said manifold and said cylinder head.
Claim 4
Dependent Claim
27 words
Apparatus for the elastic attachment of the exhaust manifold as in claim 1 wherein the elastic means consist of at least a slotted elastic dowel or tube.
Claim 5
Dependent Claim
25 words
Apparatus for the elastic attachment of the exhaust manifold as in claim 1 wherein the elastic means consists of at least a flat wavy spring.
Claim 6
Independent Claim
162 words
A method for attachment of an exhaust manifold to the cylinder head of a motor comprising the steps of: providing upper and lower inclined support surfaces on said exhaust manifold and said cylinder head, said surfaces of both said manifold and head being defined within transversely disposed planes, arranging said inclined supporting surfaces on said exhaust manifold in facing relationship with said inclined supporting surfaces on said cylinder head, providing elastic means between either said upper or lower inclined supporting surfaces of said exhaust manifold and said cylinder head, while disposing said other surfaces of said manifold and head in contact with each other, pressing said exhaust manifold against its gasketed mating surface with said cylinder head by said elastic means disposed between either said upper or lower inclined surfaces of said exhaust manifold and said cylinder head so as to wedge said other exhaust manifold surfaces against said other cylinder head surfaces, and retaining said exhaust manifold in the present position.
Claim 7
Independent Claim
162 words
