Archery arrow
First Claim
1. An improved archery arrow, said arrow comprising, in combination:
- a. a hollow elongated arrow shaft bearing arrow vanes adjacent its rear end; and
,b. an arrow pile releasably secured to the front end of said arrow shaft, said pile comprisingi. an aerodynamically forwardly tapered down, dome-shaped hard point,ii. a hollow pile tube connected to the rear end of said point and recessed inwardly thereof, said pile tube being releasably slideably disposed in said shaft front end so that the leading edge of said shaft front end abuts the rear edge of said point to form a smooth, essentially continuous surface therewith, said pile tube being scored transversely and thus being readily breakable for shortening and lightening said tube, andiii. control means for readily adjusting and positioning the weight of said pile to adjust the spine and balance of said arrow for fine tuning.

Abstract
An improved archery arrow is provided which includes an arrow shaft with vanes adjacent its rear end, and a novel arrow pile at its front end. The pile has removable ball bearings, or a threaded weight plug, and/or a scored attaching portion which is readily breakable for shortening and lightening the pile, for controlling the weight and weight distribution of the pile in order to regulate the spine and balance of the arrow for improved performance. The pile point is of improved aerodynamically tapered, dome-shaped configuration for higher, longer flight. Alternatively the pile may have a threaded shaft extending rearwardly therefrom with a split sleeve and wedge threaded thereon. The position of the sleeve and wedge along the length of the shaft adjusts the weight distribution and expansion of the sleeve caused by insertion of the wedge therein provides a mechanism for readily adjusting the pile to fit variations in the internal diameter of the arrow shaft so as to ensure a snug fit between it and the arrow shaft, yet permit ease of installation of the pile in the shaft. The improved arrow is simple, inexpensive and durable and it exhibits improved flight performance, while permitting easy tuning of the arrow to the individual requirements of the archer and his bow.
