Abstract

Abstract A mounting for a heat producing element of an automobile is described, in which elastic support members of rubber or an elastomeric material are positioned externally of a heat shield in a position in which they are exposed to unobstructed air flow beneath the automobile, and are isolated from radiant heat produced by the heat producing element in a manner minimizing the conduction of heat from said heat producing element.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 228 words
A mounting for a heat-producing element of an automobile exhaust system which includes an upper heat shield fixedly mounted above the heat-producing element to the underside of the automobile in spaced relationship therewith, said upper shield having downwardly extending flanges paralleling a longitudinal axis of the heat-producing element and covering an upper surface and a substantial portion of the side surfaces of said heat-producing element, said mounting comprising a lower heat shield rigidly attached to said heat-producing element in spaced relationship therewith covering a lower surface thereof and having a bottom portion and upwardly extending flanges at its longitudinal edges extending upwardly into said flanges of said upper heat shield defining therebetween ventilation openings, a mounting bracket positioned adjacent the side of said lower heat shield remote from said heat-producing element and having lateral extensions perpendicular to said longitudinal axis, and elastic members connected to said lateral extensions and attached to a body member of the automobile, said upwardly extending flanges having portions which extend laterally for shielding said elastic members from heat radiated from said heat-producing element, said ventilation openings extending longitudinally and opening downwardly, said bottom portion and said flanges of said lower heat shield dissipating heat conducted from said heat producing element, said mounting bracket and said elastic members being positioned completely exteriorly of said heat shields and exposed to air flow beneath the automobile.
Claim 2
Dependent Claim 228 words
A mounting for a heat-producing element of an automobile exhaust system which includes an upper heat shield fixedly mounted above the heat-producing element to the underside of the automobile in spaced relationship therewith, said upper shield having downwardly extending flanges paralleling a longitudinal axis of the heat-producing element and covering an upper surface and a substantial portion of the side surfaces of said heat-producing element, said mounting comprising a lower heat shield rigidly attached to said heat-producing element in spaced relationship therewith covering a lower surface thereof and having a bottom portion and upwardly extending flanges at its longitudinal edges extending upwardly into said flanges of said upper heat shield defining therebetween ventilation openings, a mounting bracket positioned adjacent the side of said lower heat shield remote from said heat-producing element and having lateral extensions perpendicular to said longitudinal axis, and elastic members connected to said lateral extensions and attached to a body member of the automobile, said upwardly extending flanges having portions which extend laterally for shielding said elastic members from heat radiated from said heat-producing element, said ventilation openings extending longitudinally and opening downwardly, said bottom portion and said flanges of said lower heat shield dissipating heat conducted from said heat producing element, said mounting bracket and said elastic members being positioned completely exteriorly of said heat shields and exposed to air flow beneath the automobile.
Claim 3
Dependent Claim 51 words
The mounting according to claim 1, further comprising: axially spaced flanges of said heat producing element, means securing one end of said lower heat shield to one of said flanges, and means securing an opposite end of said lower heat shield and said mounting bracket to the other of said flanges.
Claim 4
Dependent Claim 52 words
The mounting according to claim 2, further comprising: a stay secured to said other flange of the heat producing element, bolts and lock nuts constituting said securing means, said bolts extending through said mounting bracket and said lower heat shield and being secured in apertures in the stay by said lock nuts.
Claim 5
Dependent Claim 34 words
The mounting according to claim 2, further comprising: extensions of said one flange having threaded apertures therein, said securing means comprising bolts received within said threaded apertures and which extend through said heat shield.
Claim 6
Dependent Claim 38 words
The mounting according to claim 2, further comprising: extensions of said other flange having threaded apertures therein, said securing means comprising bolts received within said threaded apertures and which extend through said heat shield and said mounting bracket.
Claim 7
Dependent Claim 59 words
The mounting according to claim 1, further comprising: hooked portions formed on said lateral extensions of the mounting bracket and which are received in apertures in the respective elastic members, and hooked members supported by the automobile body and which extend through apertures in said elastic members, the respective apertures in the elastic members being spaced from each other.
Claim 8
Dependent Claim 25 words
The mounting according to claim 1, further comprising: thermal insulation gaskets interposed between said heat producing element, said lower heat shield, and said mounting bracket.
