Abstract
Abstract A bow stringing and unstringing device for a compound bow has a stop mounted on the outer ends of resilient limbs of a compound bow to prevent movement of the outer ends of the anchor wires of the bow back over the pulleys when the bowstring is removed from the ends of the anchor wires. A stringer wire has a suitable hook for attaching the ends thereof to suitable connector, for example, an eye-bolt, also at the ends of the resilient limbs of the bow for releasing the tension on the bowstring when pulled like the bowstring so that the bowstring may be removed from the bow. A novel brace which fits between the drawn stringer wire and the bow handle is provided for maintaining the tension in the stringer wire while removing and replacing the bowstring and for carrying the stringer wire when the same is not in use.
