Abstract
A crossbow includes an elongated frame coupled to a riser at a first end thereof and attached to an upper housing at its second end generally above the trigger region. The riser supports a pair of flexible limbs, and a bowstring extends between such limbs. A bowstring retractor is provided within the upper housing and includes a rope spool used to wind a retractor rope for retracting the bowstring. First and second spool gears surround the rope spool for rotation therewith. A spur gear mounted on a drive axle engages one of the spool gears, and a crank can be engaged with the drive axle. A pawl engages the other spool gear to prevent unintentional unwinding of the retractor rope from the rope spool. A pawl release member disengages the pawl from its associated spool gear. Drawing the bowstring beyond its full draw position also disengages the pawl.
