Description

[0001] This application claims the benefit of U.S. Provisional Application 60 / 621,941 filed Oct. 26, 2004.FIELD OF THE INVENTION [0002] This invention relates to crossbows. BACKGROUND OF THE INVENTION [0003] It is well known that crossbows are difficult to cock due to the powerful limbs that are used by this equipment. Over the centuries various apparatus has been developed to provide an easier method for drawing a bow string for engagement with a trigger mechanism. Such devices have included levers, windlasses, built-in pulley systems that are attached to the stock of the bow as well portable rope and pulley means. All of these devices provided some degree of mechanical advantage. [0004] Earlier attempts to assist with cocking have been overly complex such as those described in related United States patents all by Bednar, being, U.S. Pat. Nos. 6,286,496, 6,095,128 and 6,874,491. These devices preferably are utilized in connection with additional power sources such as hand cranks, p...
