Mounting assembly for exhaust pipe

Claim 2

A mounting assembly for resiliently supporting an exhaust pipe within an aperture provided in a vehicle frame, said mounting assembly including a tubular collar having an inner diameter larger than the outer diameter of said exhaust pipe and adapted to encircle a portion of the exhaust pipe within said aperture, said collar having a pair of opposed end portions provided with circumferentially spaced and radially inwardly projecting dimples, means securing said dimples at spaced points to the outer surface of the exhaust pipe so as to provide an annular air space between said outer surface and said collar for air to flow therethrough, a ring-shaped grommet of elastomeric material adapted to be frictionally supported by said collar, a retainer bracket having a well formed therein corresponding in configuration to said grommet, a circular opening centrally formed in said well having a diameter greater than the outer diameter of said collar, said retainer bracket adapted to receive the grommet in said well and compressively secure a portion of said grommet to said frame so as to allow said exhaust pipe to be resiliently supported for longitudinal and radial movement relative to said frame.

Claim 3

A mounting assembly for resiliently supporting an exhaust pipe within an aperture provided in a vehicle frame, said mounting assembly including a collar having a pair of opposed end portions and an opening extending therethrough of a size larger than the outer diameter of said exhaust pipe and adapted to encircle a portion of the exhaust pipe that is located within said aperture, means securing said opposed end portions of said collar to the outer surface of said exhaust pipe so as to circumferentially space said collar from said exhaust pipe and provide an air chamber that surrounds the exhaust pipe for cooling air to flow into said air chamber at one end portion of said collar and out of said air chamber at the other end portion, a resilient grommet having a predetermined width and adapted to be frictionally supported by said collar, a retainer bracket having a pair of laterally extending arm portions for fastening said bracket to said vehicle frame, a well formed in said bracket corresponding in configuration to said grommet, said well having a depth dimension that is less than the dimension of said predetermined width, an opening centrally formed in said well of a size larger than the outer size of said collar, said retainer bracket adapted to receive the grommet in said well and compressively secure portions of said grommet to said frame so as to allow said exhaust pipe to be resiliently supported for longitudinal and radial movement relative to said frame when said arm portions are fastened to said frame.

Claim 4

A mounting assembly for resiliently supporting an exhaust pipe within an aperture provided in a vehicle frame, said mounting assembly including a collar having a pair of opposed end portions and an opening extending therethrough of a size larger than the outer diameter of said exhaust pipe and adapted to encircle a portion of the exhaust pipe that is located within said aperture, means securing said opposed end portions of said collar to the outer surface of said exhaust pipe so as to circumferentially space said collar from said exhaust pipe and provide an air chamber that surrounds the exhaust pipe for cooling air to flow into said air chamber at one end portion of said collar and out of said air chamber at the other end portion, a resilient grommet having a predetermined width and adapted to be frictionally supported by said collar, a retainer bracket having a pair of laterally extending arm portions for fastening said bracket to said vehicle frame, a well formed in said bracket corresponding in configuration to said grommet, said well having a depth dimension that is less than the dimension of said predetermined width, an opening centrally formed in said well of a size larger than the outer size of said collar, said retainer bracket adapted to receive the grommet in said well and compressively secure portions of said grommet to said frame so as to allow said exhaust pipe to be resiliently supported for longitudinal and radial movement relative to said frame when said arm portions are fastened to said frame.
