Abstract
Abstract In a spacer damper, each wire is pivoted to the spacer damper body with a relatively delicate current conducting sleeve in the pivot axis in addition to one or more torsion devices resisting pivotal movement. Limit means for limiting pivotal movement prevent the application of radial compressive forces to said sleeve.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
153 words
In a spacer damper; a spacer body member; an arm member for supporting a conductor; a pivot shaft extending through aligned openings in said members; a conducting sleeve fitted into an opening in one of said members and also on said shaft providing a path for the flow of electricity between said members through said shaft; torsion means yieldingly holding said body member and said arm member against relative rotation on the axis of said shaft; said body member and said arm member including first interacting limit means and second interacting limit means angularly spaced apart relative to said pivot shaft; each of said limit means resisting forces tending to rotate said arm about the other of said limit means relative to said body member, and preventing such forces from moving said arm in a direction generally radial to said shaft, whereby radial compression of said conducting sleeve against said shaft is precluded.
Claim 2
Dependent Claim
153 words
In a spacer damper; a spacer body member; an arm member for supporting a conductor; a pivot shaft extending through aligned openings in said members; a conducting sleeve fitted into an opening in one of said members and also on said shaft providing a path for the flow of electricity between said members through said shaft; torsion means yieldingly holding said body member and said arm member against relative rotation on the axis of said shaft; said body member and said arm member including first interacting limit means and second interacting limit means angularly spaced apart relative to said pivot shaft; each of said limit means resisting forces tending to rotate said arm about the other of said limit means relative to said body member, and preventing such forces from moving said arm in a direction generally radial to said shaft, whereby radial compression of said conducting sleeve against said shaft is precluded.
Claim 3
Dependent Claim
54 words
The spacer damper of claim 1 wherein each of said first and said second interacting limit means comprises a generally radial shoulder on said arm member and a mating abutment on said body member positioned to engage the said radial shoulder following a given angular displacement of said arm member about said pivot shaft.
Claim 4
Dependent Claim
96 words
The spacer damper of claim 1, wherein said first and said second interacting limit means together include a pair of generally radial projections on said arm member and a pair of cooperating projections on said body member positioned so that one projection on said arm member will alternately engage one or the other of the projections on the said body member upon rotation of said arm member in different directions about said shaft, and the other of said projections on said arm member correspondingly will engage the remaining one of said projections on said body member.
