Abstract
Abstract The abstract is of an archery bow compensator comprising a central rod or core that is threaded at its trailing end into a bow to extend forwardly therefrom. A chamber at the forward end of the rod may be loaded with pellets to balance the rod precisely in the archer's hand. An inertia sleeve carried on the rod moves forward when the bow string is released against the force of a compression spring. When compressed, the spring thrusts the sleeve back against a stop on the core to force the bow firmly into the Vee of the archer's hand against any tendency to jump out.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
155 words
A shock compensator for an archery bow comprising: a rod adapted to be secured at one end to an archery bow to extend forwardly therefrom; an inertia sleeve slidably carried on said rod; an internal shoulder on said sleeve; an external member on the other end of said rod; a compression spring on said rod compressed between said internal shoulder and said external member to bias said sleeve rearward in a force to match the bow string force; opposing shoulders on said sleeve and said rod to limit rearward movement of said sleeve on said rod; resilient shock absorbing means between said opposing shoulders; said external member being threaded onto said rod to enable precise setting of the compression of said spring and having a chamber therein; a selected number of pellets in said chamber weighting said other end of said rod to balance said archery bow precisely; and a removable plug closing said chamber.
