Abstract
The inner periphery of the elastomer portion of a safetied elastomeric sandwich mount assembly is provided with a protrusion that engages the outer periphery of the rigid spacer to hold the three elements of the mount assembly together on either side of the support until the supported member such as an engine or cab of an off-highway vehicle, for example, can be bolted thereto. The protrusion also provides a centering feature that facilitates insertion of the retaining bolt.

A safetied sandwich mount assembly for securing a supported member to a support, said sandwich mount assembly including a first member comprised of an elastomeric sandwich member adapted to be positioned between said supported member and said support to cushion compressive relative movement therebetween, a second member comprised of an elastomeric sandwich member adapted to be positioned beneath said support to cushion expanding movement of said supported member relative to said support, a third member comprised of a rigid spacer member extending between said first and second elastomeric sandwich members and adapted to extend through said support, each of said first, second and third members having an axial throughbore of substantially the same diameter, said sandwich mount assembly being characterized by each of said elastomeric sandwich members having at least one internal protuberance which extends inwardly to define a dimension less than an external dimension of said third member such that when said elastomeric sandwich members are assembled with said rigid spacer member such that said first elastomeric sandwich member overlies said support and said second elastomeric sandwich member, with said third member extending substantially vertically through said support, said internal protuberances exhibit a sufficient gripping force on said rigid spacer such that said second elastomeric sandwich member and said rigid spacer are suspended on said support against a gravitational pull of their own weights and said elastomeric sandwich members are retained on said rigid spacer member prior to insertion of a retaining bolt and said axial throughbores of said three members are pre-aligned to receive said retaining bolt.
A safetied mount assembly, comprising:
- (a) first and second mounts each including a first plate having a axial throughbore, a second plate including a throughhole, and an elastomer layer bonded therebetween, said elastomer layer including an internal cavity having an internal dimension,
- (b) a rigid spacer having an external dimension extending between said first and second mounts, said external dimension being smaller than said internal dimension of said elastomer layer, and
- (c) at least one internal protuberance inwardly projecting from each elastomer layer to define a dimension less than said external dimension of said spacer whereby when said mounts are assembled with said spacer, said at least one internal protuberance on each said mount will exhibit a sufficient gripping force on said spacer to retain said assembly together prior to insertion of a retaining bolt.
A safetied mount assembly, comprising:
- (a) first and second mounts each including a first plate having an axial throughbore, a second plate including a throughhole and a projecting stem portion, and a substantially annular elastomer layer bonded therebetween, said elastomer layer including an internal cavity having an internal dimension,
- (b) a rigid spacer having an external cylindrical dimension and an axial throughbore for receiving a retaining bolt, said spacer extending through said throughholes and said cavities in said first and second mounts, said external cylindrical dimension being smaller than said internal dimension of said elastomer layer, and
- (c) a plurality of spaced apart internal elastomeric protuberances inwardly projecting from each said elastomer layer to define a dimension less than said external cylindrical dimension of said spacer whereby when said mounts are assembled with said spacer, said plurality of internal elastomeric protuberances on each said mount exhibit a sufficient gripping force on said spacer to retain said assembly together prior to insertion of said retaining bolt.
An assembly comprising a support and a safetied sandwich mount assembly for securing a supported member to said support, said sandwich mount assembly including a first member comprised of an elastomeric sandwich member positioned above said support, a second member comprised of an elastomeric sandwich member positioned beneath said support and beneath said first elastomeric sandwich member, a third member comprised of a rigid spacer member extending between said first and second elastomeric sandwich members and extending through said support, each of said first, second and third members having an axial throughbore of substantially the same diameter, said sandwich mount assembly being characterized by each of said elastomeric sandwich members having at least one internal protuberance which extends inwardly to define a dimension less than an external dimension of said third member such that when said elastomeric sandwich members are assembled with said rigid spacer member, said internal protuberances exhibit a sufficient gripping force on said rigid spacer such that said second elastomeric sandwich member and said rigid spacer are suspended on said support against a gravitational pull of their own weights and said elastomeric sandwich members are retained on said rigid spacer member prior to insertion of a retaining bolt and said axial throughbores of said three members are pre-aligned to receive said retaining bolt.
