Abstract

A pole damping system in which a hollow tubular member is attached to the wall of a hollow pole with an inertia mass in the form of a solid rod on the interior of the tube but unattached to the tube for limited movement on the interior of the tube for damping vibrations of the pole; in one embodiment the tubular member is mounted on the exterior of the pole but is mounted on the interior of the pole in another embodiment.

Claims

1. The combination of an elongated pole member, attachment means for connecting a vibration damping means to said pole member, said vibration damping means including an elongated closed chamber defining member comprising a hollow tube, an unrestricted inertia mass member comprising a cylindrical rod member mounted in said hollow tube with the interior of said hollow tube providing limited clearance with respect to the outer surface oF said rod member and relatively soft sound reducing caps on each end of said rod member whereby said cylindrical rod member is capable of limited movement in said hollow tube and serves to damp oscillations of said elongated pole member.

2. The invention of claim 1 wherein said hollow tube extends substantially parallel to said elongated pole member. claim 2 wherein said elongated pole member is of hollow tubular construction and said closed chamber defining member is mounted on the interior wall of said pole member.

4. The invention of claim 2 wherein said attachment means includes a collar extending about the exterior of said pole means.
