ABSTRACT:
A bowstring pulling and release device comprises a one-piece, T-shaped body including a handle portion forming the crossbar of the T-shaped body and a leg portion extending outwardly from the handle portion and terminating in an outer free end portion. A bowstring receiving notch is formed in the free end portion and a transverse slot is formed in the free end portion normal to the bowstring receiving notch. A lock is pivotally mounted in the transverse slot for releasably locking the bowstring in the notch. An enlarged bore extends longitudinally through the leg portion from the transverse slot into the handle portion, and a reduced bore extends from the enlarged bore through the handle portion. A latch pin is slidably mounted in the enlarged bore and is spring biased outwardly into the transverse slot. The latch pin has a latch detent at its end which extends outwardly into the transverse slot and a longitudinal extension at its other end which extends through the reduced bore. A release lever is pivotally mounted along side of the handle portion opposite from the leg portion and is adjustably connected to the longitudinal extension of the latch pin for retracting the latch pin from the transverse slot. The pivoted lock has an abutment engagable with the latch detent for securing the lock in latched position and retaining the bowstring until the latch pin is retracted by operation of the release lever.
