ABSTRACT:
The archery bowstring release device includes a hollow housing having a front end and opposite rear end. A pair of openable bowstring-engaging jaws is hinged to the front end of the housing. A trigger projects from the side of the housing and is moveable between a relaxed forward non-firing position and a rearward firing position against the biasing action of a spring. An elongated drive bar is connected to the trigger and intercepts the jaws to hold them closed when the trigger is in the non-firing position. A propelor bar is hinged for longitudinal rotation in a slot in the drive bar and extends rearwardly thereof. A spring in the housing bears against the rear portion of the propellor bar when the trigger is in the forward position and against the front portion of the propellor bar when the trigger is in the firing position. A moveable detent intercepts the propellor bar, preventing firing, if the trigger is moved rapidly rearwardly. If the trigger is moved slowly rearwardly the spring has sufficient time to rotate the propellor bar out of the way of the detent, permitting firing of the device, thus assuring smooth proper firing.
