Abstract
Abstract A resilient mounting intended primarily to withstand compressive loading is of a tubular and interleaved construction comprising a pair of end plates and an intermediate annular plate which serves to stiffen a tubular elastomeric body provided between the end plates. A buffer member is secured to one of the end plates and extends longitudinally within the tubular body to lie normally free from contact with the tubular body. A protective cushioning layer provided between the buffer member and internal edge of the intermediate plate prevents direct contact between the buffer member and intermediate plate under transverse load.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A resilient mounting comprising: a resilient component comprising a substantially tubular body of elastomeric material located between and bonded to generally planar confronting surfaces of a pair of end members, said body of elastomeric material being reinforced by an embedded annular reinforcement element of generally planar form arranged to lie between and substantially parallel with said confronting surfaces of the end members, and a first of said end members being of an annular form, a bummer member secured to a second of said members and located within the internal cavity defined by the tubular body to lie spaced from the internal surface of the tubular body when the mounting is an unstressed condition, said buffer member extending axially over substantially the entire length of said internal cavity, and a buffer layer of elastomeric material provided between at least the buffer member and each of the reinforcement element and said first end member to prevent direct contact therebetween when the mounting is subject to transverse load.
Claim 2
Dependent Claim
165 words
A resilient mounting comprising: a resilient component comprising a substantially tubular body of elastomeric material located between and bonded to generally planar confronting surfaces of a pair of end members, said body of elastomeric material being reinforced by an embedded annular reinforcement element of generally planar form arranged to lie between and substantially parallel with said confronting surfaces of the end members, and a first of said end members being of an annular form, a bummer member secured to a second of said members and located within the internal cavity defined by the tubular body to lie spaced from the internal surface of the tubular body when the mounting is an unstressed condition, said buffer member extending axially over substantially the entire length of said internal cavity, and a buffer layer of elastomeric material provided between at least the buffer member and each of the reinforcement element and said first end member to prevent direct contact therebetween when the mounting is subject to transverse load.
Claim 3
Dependent Claim
55 words
A resilient mounting according to claim 1 wherein said elastomeric material of the tubular body is arranged to extend over the inner edge of the annular reinforcement element thereby to act as said buffer layer to prevent direct contact of the reinforcement element with the buffer member when the mounting is subject to transverse load.
Claim 4
Dependent Claim
36 words
A resilient mounting according to claim 1 wherein one of said end members is an annular member and the elastomeric material of the tubular body is arranged to extend over the inner edge of that member.
Claim 5
Dependent Claim
22 words
A resilient mounting according to claim 1 wherein as considered in longitudinal cross-section the internal surface of the tubular body is straight.
Claim 6
Dependent Claim
19 words
A resilient mounting according to claim 4 wherein the internal surface of the tubular body has a cylindrical shape.
Claim 7
Dependent Claim
38 words
A resilient mounting according to claim 1 wherein the buffer member comprises a head portion lying externally of the internal cavity, said head portion being provided with axial buffer means to restrict longitudinal extension of the tubular body.
Claim 8
Dependent Claim
43 words
A resilient mounting according to claim 6 wherein the buffer member comprises a sleeve of rigid material clamped between said head portion and said one of said end members and arranged as a buffer surface which confronts the bore of the tubular body.
