Abstract
Abstract Applicant has provided a method for making a vibration damper for damping harmonic vibrations in brake resurfacing operations made up of an elastic tube with slugs of heavy ductile material in it. The slugs are approximately the same diameter as the inside diameter of the tubing and are held in place in the tubing by frictional force or by cement. One slug is used to join the adjacent ends of the tubing. The loop formed by the tubing is placed on a brake drum or disc brake rotor during resurfacing operations. The slugs are coated with liquid cement which lubricates them to reduce friction in getting them into place. The end slug functions to hold the tube ends together and also to function as one of the weights.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
166 words
The method of making a vibration damper comprising providing a length of elastic tubing made of latex material having a hollow therein and having two ends, providing cylindrical shaped weights made of ductile material of substantially the same diameter as said hollow, providing a cement material for providing a lubricant for said weights during assembly, coating said weights with said cement, placing said weights into said hollow in said elastic tubing to approximately equal spacing in said elastic tubing, bringing the ends of said elastic tubing close together and sliding one said ductile weight into both of said ends of said elastic tubing, thereby connecting the ends of said elastic tubing together over each end of one of said weights for holding said tubing in a continuous loop, and bending each said ductile weight to have a radius of curvature substantially equal to the radius of curvature of said loop, curing said cement wherein said weights are held in position in said tubing by said cement.
