Abstract
Abstract A high axial rate resilient bushing comprising an annular molded rubber insert radially compressed between an inner rigid sleeve and an outer sleeve having flanges at either end can be press fitted into an automobile frame even though the diameter of the flanges is greater than that of the opening in the frame. This is achieved through the use of a two-piece telescoping outer sleeve each piece forming one of said flanges. The bushing can be used, for example, in the shackle spring of an automobile.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
192 words
In the combination of a pair of spring shackle arms, a vehicle frame member having an annular passageway therethrough and a resilient bushing interconnecting said shackle arms and said frame member, said bushing comprising a molded elastomeric insert, an inner cylindrical sleeve, and an outer sleeve concentric with and shorter than the inner sleeve and having a radially outwardly extending flange at both ends thereof, said insert radially compressed between the sleeves and extended axially beyond the ends of the inner sleeve before assembly of the bushing between said shackle arms and snubbed against the outer flanges after assembly, the improvement wherein said outer sleeve is composed of a first tubular flanged part in contact with the outer surface of the insert and positioned through said annular passageway in said frame member, and a second part press fitted around the first tubular part and in said annular passageway in said frame member, wherein the outer diameter of the flanges on each of said first and second parts is larger than the diameter of the annular passageway through said frame member and wherein said flanges are on either side of the frame member.
Claim 2
Dependent Claim
192 words
In the combination of a pair of spring shackle arms, a vehicle frame member having an annular passageway therethrough and a resilient bushing interconnecting said shackle arms and said frame member, said bushing comprising a molded elastomeric insert, an inner cylindrical sleeve, and an outer sleeve concentric with and shorter than the inner sleeve and having a radially outwardly extending flange at both ends thereof, said insert radially compressed between the sleeves and extended axially beyond the ends of the inner sleeve before assembly of the bushing between said shackle arms and snubbed against the outer flanges after assembly, the improvement wherein said outer sleeve is composed of a first tubular flanged part in contact with the outer surface of the insert and positioned through said annular passageway in said frame member, and a second part press fitted around the first tubular part and in said annular passageway in said frame member, wherein the outer diameter of the flanges on each of said first and second parts is larger than the diameter of the annular passageway through said frame member and wherein said flanges are on either side of the frame member.
Claim 3
Dependent Claim
26 words
The combination of claim 1 wherein the axial length of the second flanged part is substantially the same length as that of the first flanged part.
Claim 4
Dependent Claim
5 words
telescopically engaging said bushing sleeve.
Claim 5
Dependent Claim
5 words
telescopically engaging said bushing sleeve.
Claim 6
Dependent Claim
48 words
The combination of claim l wherein the first flanged part has a shoulder which serves to register the bushing with respect to the annular passageway in said frame member and the second flanged part has a shoulder which serves to register it with respect to said frame member.
Claim 7
Dependent Claim
111 words
In an elastomeric bushing having a tubular elastomeric insert radially compressed between inner and outer sleeve members, said outer sleeve member having a radially outwardly extending, annular flange at each end thereof and said elastomeric insert having end portions extending axially beyond the ends of both of said inner and outer sleeve members such that said end portions can be snubbed against said flanges of said outer sleeve member, the improvement wherein said outer sleeve member comprises: A. a tubular bushing sleeve having a radially outwardly extending, annular flange at one end thereof, and B. a sleeve cap l. having a radially outwardly extending, annular flange at one end thereof, and
Claim 8
Dependent Claim
111 words
In an elastomeric bushing having a tubular elastomeric insert radially compressed between inner and outer sleeve members, said outer sleeve member having a radially outwardly extending, annular flange at each end thereof and said elastomeric insert having end portions extending axially beyond the ends of both of said inner and outer sleeve members such that said end portions can be snubbed against said flanges of said outer sleeve member, the improvement wherein said outer sleeve member comprises: A. a tubular bushing sleeve having a radially outwardly extending, annular flange at one end thereof, and B. a sleeve cap l. having a radially outwardly extending, annular flange at one end thereof, and
Claim 9
Dependent Claim
23 words
The bushing defined in claim 4 further characterized in that said sleeve cap is substantially the same axial length as said busHing sleeve.
Claim 10
Dependent Claim
51 words
The bushing as defined in claim 4 further characterized in that said bushing sleeve is provided with a shoulder axially spaced from said annular flange thereof adapted to limit the amount of axial passage of said sleeve through an opening having a diameter less than the diameter of said annular flange.
Claim 11
Dependent Claim
51 words
The bushing as defined in claim 4 further characterized in that said sleeve cap is provided with a shoulder axially spaced from said annular flange thereof adapted to limit the amount of axial passage of said sleeve through an opening having a diameter less than the diameter of said annular flange.
Claim 12
Dependent Claim
49 words
The bushing as defined in claim 6 further characterized in that said sleeve cap comprises a shoulder axially spaced from said annular flange thereof adapted to limit the amount of axial passage of said sleeve through an opening having a diameter less than the diameter of said annular flange.
