Fletching alignment nut
First Claim
1. For use in association with an arrow broadhead having a blades symmetrically arranged around its periphery and an arrow shaft having fletching symmetrically secured around its periphery in number equal to the number of blades, apparatus for coupling a broadhead and a shaft comprising:
- a cylindrical stem having first means formed at its forward end for coupling with the rearward end of a broadhead and having second means formed at its rearward end for coupling with the forward end of a shaft and having threads therebetween formed on the exterior surface of the stem; and
a cylindrical cap having internal threads received on the threads of the stem whereby rotation of the cap with respect to the stem will allow for the adjustment of the rotational position of a broadhead with respect to a shaft when coupled to the stem.

Abstract
An arrow which includes a broadhead having a tapered body with axial blade receiving slots formed therein and an axial aperture formed in the rearward end thereof, a point coupled to the forward end of the body, and blades removably received in the slots with their forward ends removably secured in position by the point and with their rearward ends extending rearwardly of the body. The arrow also includes a shaft having a nock at the rearward end therof, an axial aperture formed in the foward end thereof and fletching symmetrically arranged around its periphery adjacent to the nock equal in number to the number of blades. The arrow also includes an assembly coupling the broadhead and shaft. The assembly comprises a cylindrical stem having cylindrical surfaces formed on its forward and rearward ends coupled to the axial apertures in the rearward end of the broadhead and the forward end of the shaft and intermediate external threads therebetween. The assembly also includes a cylindrical cap having internal threads received on the intermediate threads whereby rotation of the cap with respect to the stem will adjust the axial position of the cap along the length of the stem allowing for the varying of the rotational position of the broadhead with respect to the shaft. The assembly yet further includes an adjusting washer positionable for correcting rotational non-symmetry of the arrow.

9. An arrow including, in combination:
-
a broadhead having a tapered body with a plurality of axial blade receiving slots symmetrically formed around the periphery thereof and an axial aperture formed in the rearward end thereof, a point coupled to the forward end of the body, and blades removably received in the slots with their forward ends removably secured in position by the point and with their rearward ends extending rearwardly of the body; a shaft having a nock at the rearward end thereof, an axial aperture formed in the forward end thereof and fletching symmetrically secured around its periphery adjacent to the nock equal in number to the number of blades; and
an assembly coupling the broadhead and shaft comprising a cylindrical stem having a cylindrical forward end coupled within the rearward end of the broadhead and having a cylindrical rearward end coupled within the forward end of the shaft and having intermediate external threads formed therebetween, the assembly also including a cylindrical cap having internal threads received on the intermediate threads of the stem whereby rotation of the cap with respect to the stem will move the cap along the length of the stem allowing for the varying the rotational position of the broadhead and shaft with respect to each other. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
