ABSTRACT:
A bowstring release includes a handle, a bowstring catch, and a link between the handle and catch. The catch includes a hook for retaining the bowstring, and a cam for holding and releasing the hook. The handle is initially rotatably mounted with respect to the link, so as the bowstring is drawn, the cam will retain the hook to hold the bowstring regardless of handle position. The handle has a spring-biased piston, and the link has one hole that can receive the piston. At full draw, the archer may rotate the handle so the piston will enter the hole in the link, locking the handle and link together. Further rotation of the handle will cause the link and attached cam to rotate out of engagement with the hook, to release the bowstring.
