Abstract
Abstract An insulator employing elastomeric blocks in compression and in shear is disclosed. It comprises an inner member having a wedge, an outer member around the wedge and spaced therefrom and two resilient means, each including alternative layers of rigid plates and elastomeric blocks, disposed on the opposite sides of the wedge and operatively connected between the wedge and the outer member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
232 words
An insulator comprising: an inner member with an axis having a wedge, said wedge including two surfaces which are inclined toward each other and disposed symmetrically about said axis; an outer member around said wedge and spaced therefrom; and two resilient means, each including alternate layers of rigid plates and elastomeric members, an inner one of said alternate layers of each of said two resilient means being connected to one of said two surfaces of said wedge and an outer one of said alternate layers being connected to said outer member, said rigid plates of each of said two resilient means being disposed in parallel to one of said two surfaces of said wedge; said inner member having two elastomeric parts on said wedge, each of said two elastomeric parts of said inner member being compressed between said wedge and said outer member to limit movement of said inner member relative to said outer member in a direction which is parallel to said two surfaces of said wedge and perpendicular to said axis, said outer member having a tubular section having two open ends and said inner member having two axially spaced end members spaced from said two open ends of said tubular section and two elastomeric parts fixed to said end members, respectively, to limit movement of said inner member relative to said outer member in a direction along said axis.
Claim 2
Dependent Claim
232 words
An insulator comprising: an inner member with an axis having a wedge, said wedge including two surfaces which are inclined toward each other and disposed symmetrically about said axis; an outer member around said wedge and spaced therefrom; and two resilient means, each including alternate layers of rigid plates and elastomeric members, an inner one of said alternate layers of each of said two resilient means being connected to one of said two surfaces of said wedge and an outer one of said alternate layers being connected to said outer member, said rigid plates of each of said two resilient means being disposed in parallel to one of said two surfaces of said wedge; said inner member having two elastomeric parts on said wedge, each of said two elastomeric parts of said inner member being compressed between said wedge and said outer member to limit movement of said inner member relative to said outer member in a direction which is parallel to said two surfaces of said wedge and perpendicular to said axis, said outer member having a tubular section having two open ends and said inner member having two axially spaced end members spaced from said two open ends of said tubular section and two elastomeric parts fixed to said end members, respectively, to limit movement of said inner member relative to said outer member in a direction along said axis.
Claim 3
Dependent Claim
54 words
An insulator as claimed in claim 1, in which said outer layer is a rigid plate and in which a spacer in the form of a block of elastomeric material fills a space between said outer layer and said outer member to hold said outer layer in proper inclination relative to said outer member.
Claim 4
Dependent Claim
45 words
An insulator as claimed in claim 1, in which said outer layer is a rigid plate and in which a spacer in the form of a turned portion formed on said outer layer holds said outer layer in proper inclination relative to said outer member.
