Title:
BROAD HEAD ARROWHEAD
United States Patent 3653664
Abstract:
A broad head arrowhead having two substantially flat, opposite surfaces converging toward a point; the surfaces being separated by a tapered cylinder in the center of the arrowhead for the reception of a shaft; a first side of the one flat surface extending beyond a first side of the second flat surface and a second side of the second flat surface extending beyond the second side of the first flat surface providing air pressures for causing rotation and stability.

BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a broad head arrowhead and more particularly to a broad head arrowhead utilizing four cutting edges on two converging flat surfaces.
According to the invention, a broad head arrowhead is provided having two converging flat surfaces resulting in a broad head with four cutting edges and essentially two blades. This unique construction results in a stabilizing spin to the arrow as it passes from the bow to the target. It also presents maximum cutting with minimum resistance at the target, itself, which is especially important in hunting game.
An object of the present invention is the provision of a broad head arrowhead having a minimum of resistance to travel and penetration, together with maximum stability.
Yet another object of the invention is the provision of a broad head arrowhead which is inexpensive to manufacture and extremely effective in use.
Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawing in which like reference numerals designate like parts throughout the FIGS thereof and wherein:
FIG. 1 is a perspective view of the preferred embodiment of the invention;
FIG. 2 is a top view of the embodiment of FIG. 1;
FIG. 3 is a end view of the embodiment of FIG. 1; and
FIG. 4 is a side view of the embodiment of FIG. 1.
DETAILED DESCRIPTION OF THE DRAWING
Referring to FIG. 1, the broad head arrowhead of the present invention is shown having a top surface 8 and a bottom surface 9 converging toward a point 10. Top surface 8 has one edge 11 extending beyond bottom surface 9 and bottom surface 9 has one edge 12 extending beyond top surface 8. Top surface 8 and bottom surface 9 are separated by a tapered cylinder 16 for the reception of an arrow shaft therein.
Referring to FIG. 2, edge 12 of bottom member 9 is shown extending beyond top member 8 and edge 11 of top member 8 is shown extending beyond edge 18 of bottom member 9.
Referring to FIG. 3, an end view is shown with tapered bore 16 for the reception of an arrow shaft therein. Shown also are sides 13 and 14 of tapered cylinder 16. Surfaces 19 and 21, due to their tapers and convergence, create air pressures causing rotation of the arrow in flight.
Referring to FIG. 4, a side view is shown showing side 13, top member 8, bottom member 9, and point 10.
OPERATION
Referring now to all of the FIGS of the drawing, in operation it can be seen that outside surfaces of members 8 and 9 will present a minimum of resistance to the air while providing four cutting edges. The extensions of edges 11 and 12 beyond bottom surfaces 9 and 8, respectively, set up air pressures which result in a rotation of the arrow in flight and, at the same time, lend stability due to the flat surfaces separating the cutting edges. This construction allows the arrow to be utilized with lighter bows and has the advantage that all edges can be sharpened, when required.
It should be understood, of course, that the foregoing disclosure relates to only a preferred embodiment of the invention and that it is intended to cover all changes and modifications of the example of the invention herein chosen for the purposes of the disclosure which do not constitute departures from the spirit and scope of the invention.

DETAILED DESCRIPTION OF THE DRAWING
Referring to FIG. 1, the broad head arrowhead of the present invention is shown having a top surface 8 and a bottom surface 9 converging toward a point 10. Top surface 8 has one edge 11 extending beyond bottom surface 9 and bottom surface 9 has one edge 12 extending beyond top surface 8. Top surface 8 and bottom surface 9 are separated by a tapered cylinder 16 for the reception of an arrow shaft therein.
Referring to FIG. 2, edge 12 of bottom member 9 is shown extending beyond top member 8 and edge 11 of top member 8 is shown extending beyond edge 18 of bottom member 9.
Referring to FIG. 3, an end view is shown with tapered bore 16 for the reception of an arrow shaft therein. Shown also are sides 13 and 14 of tapered cylinder 16. Surfaces 19 and 21, due to their tapers and convergence, create air pressures causing rotation of the arrow in flight.
Referring to FIG. 4, a side view is shown showing side 13, top member 8, bottom member 9, and point 10.
