ABSTRACT:
The bow string release has a sear pivotally mounted in a cylindrical body and includes a string retaining finger which projects across the string receiving notch when the sear is engaged by a pull pin biased to the sear engaging position. The pull pin is slidable in a guide sleeve assembly extending through the end wall of the body through a handle which carries a trigger through which the pull pin passes. The ends of the sleeve assembly are enlarged to capture the body and handle. The body is rotatable relative to the handle and the pull pin. When the trigger is actuated it rocks about a fulcrum (its point of engagement with a washer or with the handle) to push an enlarged head on the end of the pin to pull the pin to release the sear. In one embodiment, an adjusting screw moves the enlarged head relative to the thrust washer to partly pull the pin to adjust the trigger travel necessary to release the bow string. In another embodiment the trigger has an adjusting screw which, in effect, partly pulls the trigger to adjust the travel. The trigger is mounted in the cylindrical body of the handle. A grip is rotatable on the cylindrical body. The trigger (and the cylindrical body) is rotatable relative to the grip and/or the string notch and the grip is rotatable relative to the string notch (and/or the trigger).
