Abstract
Abstract A laminated vibration isolation pad comprising first or top rigid layer of ultra-high molecular weight polyethylene material, a second layer of vulcanized elastomeric material with an additional third or bottom layer of spaced resilient vulcanized elastomeric projections. The laminated vibration isolation pad is fabricated as a unitary structure with the polyethylene layer bonded or fused to the rubber layer while being formed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
61 words
A pad for isolating the vibrations of a machine having an upper layer of ultra-high molecular weight polyethelene, a lower layer of elastomer secured to the lower surface of said upper layer, and a plurality of laterally and longitudinally spaced elastomeric projections molded to the lower surface of said lower layer to provide vibration isolation to materials loaded on said pad.
Claim 2
Dependent Claim
61 words
A pad for isolating the vibrations of a machine having an upper layer of ultra-high molecular weight polyethelene, a lower layer of elastomer secured to the lower surface of said upper layer, and a plurality of laterally and longitudinally spaced elastomeric projections molded to the lower surface of said lower layer to provide vibration isolation to materials loaded on said pad.
Claim 3
Dependent Claim
23 words
A pad for isolating the vibrations of a machine as set forth in claim 1 wherein said elastomeric projections are cylindrical rubber discs.
Claim 4
Dependent Claim
31 words
A pad for isolating the vibrations of a machine as set forth in claim 2 wherein said molded elastomer projections are thicker than said upper layer of ultra-high molecular weight polyethelene.
Claim 5
Dependent Claim
53 words
A pad for isolating vibrations, said pad having an upper layer of ultra-high molecular weight polyethylene, said layer of polyethylene having an upper surface and a lower surface, a plurality of laterally and longitudinally spaced elastomeric projections bonded to said lower surface of said upper layer to provide means for attenuation of vibration.
Claim 6
Dependent Claim
53 words
A pad for isolating vibrations, said pad having an upper layer of ultra-high molecular weight polyethylene, said layer of polyethylene having an upper surface and a lower surface, a plurality of laterally and longitudinally spaced elastomeric projections bonded to said lower surface of said upper layer to provide means for attenuation of vibration.
Claim 7
Dependent Claim
28 words
A pad for isolating vibrations as set forth in claim 4 wherein said projections have portions thereof extending into said upper layer to provide a firm bonding thereto.
