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 slideable in a guide sleeve rotatably mounted in the end wall of the body to which it is coupled. A handle is rotatably mounted on said sleeve and carries a trigger through which the pull pin passes. When the trigger is actuated it rocks about its point of engagement with a washer to push another washer against an enlarged head on the end of the pin to pull the pin to release the sear. In one embodiment a screw in the handle and bearing on the trigger can be adjusted to "partly actuate" the trigger to adjust the stroke necessary to release the bow string. In a second embodiment a screw moves the enlarged head relative to the thrust washer to partly pull the pin for the same purpose.
