Abstract
Abstract A mount for a carburetor which reduces the transfer of heat and vibration from an engine which includes an elastic support ring interposed, with a load carrying capacity, between the mounting flanges of the engine and the carburetor and a neck portion of the carburetor to eliminate metal-to-metal contact. The neck portion has an axial length sufficient to receive the carburetor mounting flange while the elastic support ring is assembled.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
A carburetor mount assembly for cantilever mounting of a carburetor on an engine to reduce heat and vibration transmission which comprises: a. a neck portion on the carburetor to be fastened to an engine, said neck portion having an annular surface groove spaced from the end of the neck portion and a face surface on the end of the neck portion, b. an elastic ring surrounding said neck portion having an annular flange portion interfitting within said groove and a radially inwardly extending portion overlying said face surface, and c. a clamping ring adapted to be fastened interfacially to an engine surrounding said elastic ring having an inner annular portion to engage axially with the said elastic ring on a radial surface to exert an axial pressure thereon adjacent said annular flange portion in a clamping position and an axially extending portion overlying and confining said ring between said radial surface and said end portion of said neck portion.
Claim 2
Dependent Claim
159 words
A carburetor mount assembly for cantilever mounting of a carburetor on an engine to reduce heat and vibration transmission which comprises: a. a neck portion on the carburetor to be fastened to an engine, said neck portion having an annular surface groove spaced from the end of the neck portion and a face surface on the end of the neck portion, b. an elastic ring surrounding said neck portion having an annular flange portion interfitting within said groove and a radially inwardly extending portion overlying said face surface, and c. a clamping ring adapted to be fastened interfacially to an engine surrounding said elastic ring having an inner annular portion to engage axially with the said elastic ring on a radial surface to exert an axial pressure thereon adjacent said annular flange portion in a clamping position and an axially extending portion overlying and confining said ring between said radial surface and said end portion of said neck portion.
Claim 3
Dependent Claim
36 words
A carburetor mount assembly as defined in claim 1 in which the neck portion has an axial dimension to receive the clamping ring leaving exposed the annular surface groove to permit assembly of the elastic ring.
Claim 4
Dependent Claim
140 words
A carburetor mount assembly for cantilever mounting of a carburetor on an engine to reduce heat and vibration transmission which comprises: a. a circular carburetor neck portion on a carburetor body having an integral annular ring outside an annular groove in an end surface thereof, b. an elastic ring at the end of said neck portion having an annular groove receiving said annular ring and having an annular ring portion received in the groove of said neck portion, and c. a clamping ring in contact with said elastic ring and out of contact with said neck portion to hold said annular rings in firm contact with said annular grooves, d. said means on said neck portion, said elastic ring and said clamping ring interengaging axially and circumferentially to provide a secure but resilient connection between a carburetor and an engine.
Claim 5
Dependent Claim
140 words
A carburetor mount assembly for cantilever mounting of a carburetor on an engine to reduce heat and vibration transmission which comprises: a. a circular carburetor neck portion on a carburetor body having an integral annular ring outside an annular groove in an end surface thereof, b. an elastic ring at the end of said neck portion having an annular groove receiving said annular ring and having an annular ring portion received in the groove of said neck portion, and c. a clamping ring in contact with said elastic ring and out of contact with said neck portion to hold said annular rings in firm contact with said annular grooves, d. said means on said neck portion, said elastic ring and said clamping ring interengaging axially and circumferentially to provide a secure but resilient connection between a carburetor and an engine.
Claim 6
Dependent Claim
165 words
A carburetor mount assembly for cantilever mounting of a carburetor on an engine to reduce heat and vibration transmission which comprises: a. a carburetor and engine, one of which has a neck portion to be clamped to the other to form the sole support for the carburetor on the engine, b. said neck portion having an integral annular ring outside an annular groove in an end surface thereof, c. an elastic ring at the end of said neck portion having an annular groove receiving said annular ring and an annular ring portion received in the groove of said neck portion, and d. a clamping ring in contact with the periphery of said elastic ring and out of contact with said neck portion to hold said annular rings in firm contact with said annular grooves, e. said means on said neck portion, said elastic ring and said clamping ring interengaging axially and circumferentially to provide a secure but resilient connection between said carburetor and said engine.
Claim 7
Dependent Claim
165 words
A carburetor mount assembly for cantilever mounting of a carburetor on an engine to reduce heat and vibration transmission which comprises: a. a carburetor and engine, one of which has a neck portion to be clamped to the other to form the sole support for the carburetor on the engine, b. said neck portion having an integral annular ring outside an annular groove in an end surface thereof, c. an elastic ring at the end of said neck portion having an annular groove receiving said annular ring and an annular ring portion received in the groove of said neck portion, and d. a clamping ring in contact with the periphery of said elastic ring and out of contact with said neck portion to hold said annular rings in firm contact with said annular grooves, e. said means on said neck portion, said elastic ring and said clamping ring interengaging axially and circumferentially to provide a secure but resilient connection between said carburetor and said engine.
Claim 8
Dependent Claim
156 words
A carburetor mount assembly for cantilever mounting of a carburetor on an engine to reduce heat and vibration transmission which comprises: a. a carburetor neck portion on a carburetor body to be mounted on an engine, b. an elastic ring around said neck portion, c. annular groove means and ring means on said neck portion and said ring portion dimensioned to interfit axially and radially, and d. a clamping ring having portions to be clamped to an engine and dimensioned to overlie said elastic ring axially out of contact with said neck portion and having annular means to apply axial pressure to one end of said elastic ring spaced away from said engine, the other end of said ring being fashioned to seal against a surface on said engine, whereby said clamping ring applies axial confining pressure on said interfitting groove and ring means and also urges said ring against an engine surface in sealing relation.
