Asymmetrical archery bow limb

Abstract

A bow limb having a lengthen member with a protrusion and or an indentation upon said limb surfaces in order to modify an asymmetrical load application. Said protrusion and or indention modify said working area of said limb to react to limb torsion. Said protrusion and indentions are varying as to the different types of construction and the amount of modification desired.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates generally to the U.S. Patent classification definitions technical field of but not limited to; Class 273 Archery / Subclass 317+ and Class 124 Mechanical guns and projectors / subclass 23.1 bow, subclass 25 crossbow, subclass 25.6 compound bow.PRIOR ART[0002]Viewing FIG. 1 and FIG. 5, An archery compound bow consists of at least a 11 riser sandwiched by a pair of 4&5 bifurcated staves or limbs, said limbs having a 3 pulley or 14 cam mounted opposite said 11 riser and positioned in a 19 cam yoke. Said 3 pulley and or 14 cams are connected with a 6 long string and a 1 pair of cables which crisscross the 13 projectile path, for example U.S. Pat. No. 3,486,495. Another example U.S. Pat. No. 4,054,118 discloses crossed cables which are pulled to one side so as to be removed from the projectile path and to minimize contact with the archery artisans body. A right hand shooter, one holding said bow with ones left hand would prefer said 12 ...

AI Technical Summary

Benefits of technology

The prior art fails to address the issues caused by torsion applied to the cam and limb, leading to negative events such as reduced energy delivery, vibration, string oscillation, friction, and cam wear. These events ultimately result in reduced projectile velocity.

Problems solved by technology

Said '118 describes an alternative way for an eccentric pulley to be used; however, it interfered with the arrow path and subsequently McKee and Segelken invent a cable adjustment deflector which does not interfere with said arrow and which deflects tension cables away from the sight window.

Said problems, such as but not limited to cam lean and limb torsion extends from the method of attaching said loose ends of said string to said cams.

While there do exist many apparatus that will attach in all manners to an archers bow, they all have similar shortcomings which is they neither provide a means to minimize said cam lean nor said limb torsion or the further acerbated problems associated with said waste energy.
