Abstract
Abstract A dynamic linear vibration damper consisting of a support member and an inertia member assembled by an elastomer for vibration damping purposes. An extension defined on the support member is received within an opening in the inertia member, and an elastomer interposed between the extension and the opening surfaces is installed under tension whereby the resiliency of the elastomer places the elastomer under compression as confined by the opening to frictionally maintain the assembly of the components.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A dynamic linear vibration damper for damping an object vibrating in a linear direction comprising, in combination, a support adapted to be attached to the object to be damped, a planar extension defined on said support having opposite substantially parallel surfaces and lying in a plane substantially parallel to the linear direction of the vibrations to be damped, an inertia member having an elongated opening defined therein receiving said support extension, said member opening having spaced surfaces in opposed spaced relation to said extension surfaces, and an elastomer under compression within said opening interposed between said support extension and said member opening whereby friction maintains the assembly of said inertia member upon said support extension.
Claim 2
Dependent Claim
115 words
A dynamic linear vibration damper for damping an object vibrating in a linear direction comprising, in combination, a support adapted to be attached to the object to be damped, a planar extension defined on said support having opposite substantially parallel surfaces and lying in a plane substantially parallel to the linear direction of the vibrations to be damped, an inertia member having an elongated opening defined therein receiving said support extension, said member opening having spaced surfaces in opposed spaced relation to said extension surfaces, and an elastomer under compression within said opening interposed between said support extension and said member opening whereby friction maintains the assembly of said inertia member upon said support extension.
Claim 3
Dependent Claim
23 words
In a linear vibration damper as in claim 1, said compression of said elastomer being produced by the elastic contraction of said elastomer.
Claim 4
Dependent Claim
37 words
In a linear vibration damper as in claim 1, said extension having a free end extending through said member opening, and an abutment mounted upon said free end preventing withdrawal of said extension from said member opening.
Claim 5
Dependent Claim
20 words
In a linear vibration damper as in claim 3, said abutment comprising a pin mounted in said extension free end.
Claim 6
Dependent Claim
44 words
In a linear vibration damper as in claim 1, said support comprising a U-shaped element having a base and leg portions, said inertia member having two spaced openings defined therein, said leg portions comprising said support extension and each extending into a member opening.
