ABSTRACT:
BACKGROUND OF THE INVENTION
This invention is related to a system for dampening the vibration produced by the wind in elongated light poles and the like. The pole structures can be seriously damaged by the force of the wind and dampening devices embodying this invention can prevent such vibration stresses from occurring.
U.S. Pat. No. 3,612,222 issued Oct. 12, 1971 to Ray C. Minor constitutes the most pertinent prior art familiar to applicant herein.
SUMMARY OF THE INVENTION
The appearance of an externally mounted vibration dampener detracts from outside appearance of the pole and is a serious objection with the Minor construction. The welding attachment suggested in the Minor patent is difficult to accomplish, since the dampener casing is located within the hollow tubular pole member. Applicant's structure is easily installed in the upper portion of the pole by means of attachment screws extending through the pole wall and into suitable threaded portions of the dampener casing.
