Abstract:
The apparatus disclosed is intended to maximize archery artisans arrow speed by replacing the traditional flat archery bow limb with a new and unique shaped V-Limb, said V-Limb is a composite material designed in an archedly ridged fashion and is capable of retaining more of the internal lateral force tension created by the effects of bending an obtuse angled bow limb then a traditional flat archery bow limb. In addition, said V-Limb has adjustable axle to axle lengths and adjustable brace heights, both of which are currently non-existent. Furthermore; V-Limb&#39;s unique x-axis shape resist vibration from torsion and limits the amount of torsion received from cam torsion resulting from string pull while providing said archery artisan a straighter string path resulting in a faster projectile.

     BACKGROUND OF THE INVENTION 
     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 
     Archery in its purest form has long been associated with the Native American bow and arrow, and while the newest style of bow is the compound bow, it was invented in the mid-20th century with 20 th  century technology. Said compound bow consisted of steel pulleys and/or cams on the ends of the staves, with a long string that criss-crosses the bow multiple times. One limb usually has an elliptical cam, which produces a sudden reduction in the draw weight of the bow when a certain point is reached. Another form had double elliptical cams but had timing problems. Bow material was commonly wood or fiberglass. Computer software had yet to be invented that could demonstrate stress and g-force generated upon staves, strings and elliptical pulleys. Arrow speed was comparably slow at 200 fps and archery bows had a typical “C” shape. Typically, archery bows described can be bought in expensively. 
     In the 21 st  century, computers and software technology have advanced archery as archery equipment has seen dramatic advances in aluminum and magnesium composite limb systems, parallel limb design, limb turrets, cam module, idler module, carbon tension cable and strings, power and buss cables, cable and string suppressors, inertia tungsten carbide weight disks embedded into cams and string grubs. The aforementioned advances and innovations have brought the modern compound bow to where it is today. Arrow speeds now reach 340 fps, computerized numerical controlled machines bend, form or vacuum composite material into variations of rectangular shapes with beyond parallel dual limbs tipped with cam modules, idler modules, string suppressors etc. 
     While archery equipment and compound bow performance advances have continued to rise, so has the price of this 21 st  century technology, high performance archery bows cost upwards of $1,200. While there do exist many fanciful apparatus that will attach in all manners to an archers bow, they all have similar shortcomings which is none provide axle to axle adjustment nor adjustable brace heights. Also, other problems associated with prior art archery bows such as but not limited to, a small expansion and compression area on the limb; and upper limb and lower limb torsion (limb roll); and cam torsion (cam lean); and string oscillation in the string path; and vibration caused by oscillation of limbs during and post projectile release; and the narrow limb profile which limits advertising and branding surface area. 
     Additionally, said prior art fails to take advantage of opposing lateral forces working against each other to create a more powerful bow limb capable of delivering greater tension to the archers bow string thus supplying a greater thrust to the archers arrow; in short, greater feet per second speed of the archers arrow. 
     Accordingly, a need remains for ARCHERY BOW V-LIMB in order to overcome the above-noted shortcomings. The non-limiting exemplary embodiments satisfies such a need by providing an apparatus that is convenient and easy to use, lightweight yet durable in design, versatile in its applications, and designed for easily and conveniently adjusting the axle to axle length and adjusting brace heights on archery bows. Additionally, said invention allow less torsion to transfer into said limb which reduces torsion on said cam, resulting in less said string friction which result in a faster projectile.

     limb leg  1 ;   opposed limb leg  2 ;   cam  3  (not part of this invention);   vertical and horizontal adjustment ports  4 ;   cam axle mount  5 ;   limb to riser compression plate  6 ;   limb to riser compression plate bolt  7 ;   limb to riser compression plate bolt adjustment port  8 ;   fulcrum point  9 ;   flat limb Leg  10 ;   opposed flat limb leg  11 ;   string  12 ;   riser  13 ;   nut  14 ;   bolt  15 ;   flat limb expansion Area  16 ;   flat limb compression Area  17 ;   V-Limb expansion Area  18 ;   V-Limb compression Area  19 .   

     Viewing  FIG. 1 , a side view of a traditional archery bow is shown having a riser  13  sandwiched between limbs  10  &amp;  11 , said limbs  10  &amp;  11  attach by use of a compression fitting or bolt  7 . At the opposite end of limb  10  &amp;  11  away from riser  13  is a cam  3  on which a string  12  is placed around and attached to the opposing limb cam. Tension is applied to said compression bolt  7  and as said limbs pull on said string  12 , tension is created upon said string  12 . 
     In an opening embodiment and Viewing  FIG. 2  said invention constructed of a ridged material such as but not limited to a dense, vibration absorbing material, rigidly molded, solid piece of a physically toughened structurally complementary substances, especially metals, ceramics, glasses, and polymers, combine to produce structural and functional properties not present in any individual component. Additionally viewed in  FIG. 2  is V-Limb expansion area  18  and V-Limb compression area  19 . 
     Yet in another embodiment all of said physically toughened structurally complementary substances are waterproof. 
     A further embodiment also viewed on  FIG. 3 , and  FIG. 4 , an adjustable axle to axle length. Shown limb leg  1  and opposed limb leg  2  and cam  3  (not part of this invention); and vertical and horizontal adjustment ports  4  and Cam axle mount  5  and having a convex or outward curvation extending parallel along the spine of said limbs  1  and  2 , having a notch in one end capable of housing such as but not limited to an archery bow limb cam  3  module and having an archery bow riser mounting apparatus located opposite end Said said vertical and horizontal adjustment ports  4 . 
     An additional embodiment viewed on  FIG. 6 , describes said invention attaching by such as but not limited to, a limb to riser compression plate  6 , limb to riser compression plate bolt  7  and limb to riser compression plate bolt adjustment port  8 . As limb legs  1  and  2  are inserted into said limb to riser compression plate  6  and seated, an artisan inserts a tool into and through limb to riser compression plate bolt adjustment port  8  and either tightens or looses said bolt thus securing or removing said invention from said riser (not part of this invention). Also, said invention can be attached to many traditional archery bows by using the fulcrum point  9  located beneath said limb to riser compression plate  6  and behind said limb to riser compression plate bolt  7 . 
     Viewing  FIG. 5 , a further preferred embodiment is a description of the shape used to maximize spring return ratio such as but not limited to a sweeping arch. Viewing said invention from the top view, the reader can see the unique shape designed to create greater tension across the cross sectional shape thus transferring the potential energy into said string yielding a greater tension then traditional flat archery bow limbs. 
     Such a structural configuration provides the unexpected and unpredictable advantage of x-axis and y-axis rigidity while also providing a greater ratio of tension delivered to the archer&#39;s bow string over traditional flat limb technology currently used on archery equipment thus resulting in greater feet per second speed of the projectile. 
     While the invention has been described with respect to a certain specific embodiment, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention. In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the non-limiting exemplary embodiments may include variations in size, materials, shape, form, function and manner of operation.
