Abstract

The arrow includes an elongated shaft having spaced rear stabilizing vanes extending generally longitudinally and diagonally, and a broadhead detachably connected to the front of the shaft. The broadhead has an elongated central core with slots receiving spaced sharp blades held in place at their front tips by a point releasably screwed to the front end of the core and at their rear ends by a ring which fits over notched blade portions. The broadhead includes spaced front stabilizing vanes extending generally longitudinally and diagonally in the same direction as the rear vanes to greatly increase arrow spin, speed, shooting accuracy and killing power. The front vanes may be all of each of the blades themselves or their bent rear portions or may be separate vanes disposed in a fitting at the rear of the core. The point can have chiseled diagonal outer recesses for better bone penetration. The broadhead and arrow are inexpensive, durable and efficient.

Claims

1. An improved hunting arrow, said arrow comprising, in combination:

a. an elongated arrow shaft;

b. stabilizing arrow fletching connected to the rear end of the shaft, said fletching comprising a plurality of spaced rear stabilizing vanes extending generally longitudinally and peripheral of said shaft, said rear vanes being disposed diagonally in a selected direction relative to the longitudinal axis of said shaft; and

,

c. a broadhead connected to the front of said shaft, said broadhead comprising a longitudinally extending central core, a plurality of spaced sharp blades the bases of which are releasably received in slots in said core and which extend peripherally thereof, a point releasably screwed to the front end of said core and defining a blade front tip-receiving rear space, the front tips of said blades being releasably held in said rear space by said point, said core having a rear ring slideably received thereover, the rear end of each said blade having a ring-receiving notch, a portion of said blade rear end being releasably seated within said ring, the rear of said core terminating in a fitting secured thereto and having an annular shoulder against which said ring rests and which limits the rearward movement of said ring relative to said core, said fitting being releasably screwed to the front of said shaft, and a plurality of spaced front stabilizing vanes connected to said core, extending generally longitudinally and peripherally thereof and disposed diagonally in the same direction as said rear stabilizing vanes to increase rotation and accuracy of said arrow.

2. The improved arrow of claim 1 wherein said blades comprise said front stabilizing vanes.

3. The improved arrow of claim 1 wherein the rear portion of each of said blades is bent to angle diagonally and form said front stabilizing vanes.

4. The improved arrow of claim 1 wherein said broadhead includes a separate rear fitting containing said front stabilizing vanes.

5. An improved broadhead for a hunting arrow, said broadhead comprising, in combination:

a. a longitudinally extending central core containing a plurality of spaced slots;

b. a plurality of spaced sharp blades releasably disposed in said slots and extending peripherally thereof, the rear end of each said blade having a ring-receiving notch;

c. a point releasably secured to the front end of said core and defining a blade front tip-receiving rear space, the front tips of said blades being releasably held in said rear space by said point;

d. a rear ring slideably received over said core and resting against a rear fitting which is secured to said core and contains an annular shoulder limiting rearward movement of said ring, said ring being disposed within said notches to releasably seat said blades; and

,

e. a plurality of spaced front stabilizing vanes connected to said core, extending longitudinally and peripherally thereof and disposed diagonally relative to the longitudinal axis of said core.

6. The improved broadhead of claim 5 wherein the front tip of each of said blades fits under and is releasably held by said point.

7. The improved broadhead of claim 6 wherein said point is releasably screwed to said core and defines a blade tip-receiving rear space, wherein the rear of said core is releasably screwed to the front of said shaft, and wherein said blades are flat, bear a razor edge and have a rear ring-receiving notch.

8. The improved broadhead of claim 6 wherein said blades comprise said front stabilizing vanes.

9. The improved broadhead of claim 6 wherein the rear portion of each of said blades is bent to angle diagonally and form said front stabilizing vanes.

10. The improved broadhead of claim 6 wherein said broadhead includes a rear fitting containing said front stabilizing vanes.

11. The improved broadhead of claim 6 wherein said point includes elongated outer recesses which extend generally longitudinally and diagonally in the same direction as said vanes.

12. The improved broadhead of claim 6 wherein said core is reversible end to end and wherein said broadhead includes a rear fitting disposed between and screwed to said core and said shaft.
