Abstract

With the use of a smaller tube which fits inside the nock end of a arrow shaft and the smaller tube having molded in it spiraled grooves which acts upon dimples that are molded in the arrow shaft body and when the bowstring drives the smaller tube into the arrow shaft causeing the whole arrow shaft to spinn, the results of which allows the arrow shaft to oscillate less, fly stright without vanes, and faster with more peneration and will enter a close range target stright.

Claims

1. A vaneless arrow shaft combination comprising;

a hollow cylindrical arrow shaft body having a plurality of dimples circumferentially arranged along its interior surface;

a cylindrical spinner tube having a plurality of spiral grooves circumferentially arranged along its exterior surface, and a nock at its rear end to engage with the bowstring of a bow;

the spinner tube adapted to be inserted within the arrow shaft body;

the spiral grooves on the spinner tube adapted to engage with the dimples on the shaft boby when the spinner tube is inserted into the shaft body;

whereby when the bowstring is stretched and than released the engagement between the spiral grooves and the dimples impart rotation to the arrow shaft body.

2. The method of imparting spin to an arrow shaft comprising;

providing a hollow cylindrical arrow shaft body having a plurality of dimples circumferentially arranged along its interior surface;

providing a spinner tube having a plurality of spiral grooves circumferentially arranged along its exterior surface; and

a nook at its rear end to engage with the bowstring of a bow;

inserting the spinner tube inside the hollow shaft body so that the spiral grooves on the exterior surface of the spinner tube engage with the dimples on the interior surface of the shaft body;

engaging the nook at the end of the spinner tube with the bowstring of a bow;

stretching and than releasing the bowstring to impart rotation to the shaft body via the engagement between the spiral grooves and the dimples.
