ABSTRACT:
A bowstring archery bow breech structure having a trigger for releasing the drawn bowstring solely by the physical action of the shooter, wherein a spring mechanism is provided which functions to impart a lost motion action to the pull at a preselected drawstring pull force, wherein the trigger is designed to be pulled by the shooter in an axial direction during the lost motion action and as the result of the lost motion movement of the shooters hand rather than by any independent manipulation of the trigger by the shooter fingers, and wherein the keeper structure is formed with a unique configuration of a shoulder and peg for holding a keeper loop and the bowstring in a more axial position with respect to the arrow axis during the non-firing and the bowstring release stages, and wherein shoulder means is provided for holding the pulled bowstring without the use of a keeper loop.
