Arrow
First Claim
1. An arrow comprising a shaft with a forward end and rearward end, vane means extending along said shaft adjacent said rearward end, said vane means including first and second vanes spaced from said shaft and on the same side of said shaft, said first vane being disposed to angle downwardly from front to rear relative to said shaft and said second vane being disposed to angle upwardly from front to rear relative to said shaft, said vanes being substantially coextensive with one another longitudinally of said shaft.

Abstract
An arrow comprising a shaft with forward and rearward ends. An integral plastic vane member extends along the shaft adjacent the rearward end and includes first and second vanes spaced from the shaft by a pair of spaced generally parallel support vanes. The support vanes are interconnected by a base portion which may take one of various configurations for engaging the arrow shaft. The first and second vanes are generally triangular in configuration and are planar; however, one of the first and second vanes is disposed so as to angle downwardly from the front to the rear relative to the shaft while the other vane is disposed to angle upwardly from front to rear relative to the shaft to induce rotation of the arrow shaft during flight. The support vanes can also be spiralled to induce rotation. Thus, the first and second vanes and the first and second support vanes provide four vanes from one integral piece of plastic and all of which perform an aerodynamic function.

24. Vane means of the type for attachment to an arrow shaft comprising:
- support means having first and second ends and adapted at said first end for attachment to the shaft of an arrow, first and second vanes extending from said second end of said support means, said first and second vanes extending from said support means laterally in opposite directions and being substantially coextensive with one another from front to rear, said first and second vanes being disposed in respective planes which cross one another as viewed in side elevation with respect to said support means.
