  • Patent number: 4249507
    Abstract: A bowstring draw and release device has a frame in which a hammer is mounted in such a way as to cooperate with a trigger and latch to effect release of the bowstring with a relatively low trigger pressure. The device includes a frame having a recess in its front end and a pivotal latch member adapted to extend across the recess for engaging a loop which is formed into a bight around the bowstring. The latch is tripped to afford offslipping of the loop and hence release of the bowstring and arrow engaged therewith. A latch sear is releasably engaged with the latch and has a portion disposed in the path of movement of a spring biased hammer normally held in a cocked position by a hammer sear connected to the trigger. A suitable handgrip extends rearwardly from the frame and is designed to enable the user to actuate the trigger with his index finger.
