ABSTRACT:
The archery bow assembly includes an archery bow such as a compound bow or recurve bow having a pair of spaced, flexible, resilient bow limbs, a handle interconnecting the bow limbs, a bowstring connected to the bow limbs and an arrow rest. The assembly also includes a pair of draw weight-increasing components releasably secured, as by bolts, screws and/or brackets, to the bow limbs, preferably to the front surfaces thereof. Such components could also be attached to the rear surfaces of the bow limbs, if desired. The draw weight-increasing components are in the form of elongated, flexible resilient strips or rods of wood, metal, rubber, plastic, composites of carbon or graphite or boron fiber and plastic and mixtures thereof and are placed flush with the bow limb front and/or rear surfaces or in longitudinal grooves therein. The draw weight-increasing components are simple, inexpensive, durable and effective to increase the draw weight any desired amount. Different ones of such components can be substituted rapidly to change the draw weight and thus allow a single bow to be used for a variety of purposes, for example, target practice, indoors and outdoors, as well as for hunting.
