Arrowhead

Abstract

An arrowhead includes a generally longitudinal body portion, one end of which is pointed and the other end of which is blunt. A pair of arcuate blades extend from different sides of the body portion to curve up and over opposite faces of the portion in a generally semicircular manner. A pair of triangular blades, each formed from a corresponding one of the arcuate blades, extend from a corresponding side of the longitudinal portion and at a right angle thereto in a direction generally opposite the direction in which the corresponding arcuate blade extends.

Description

BACKGROUND OF THE INVENTION

This invention relates to hunting arrowheads suitable for providing a large cut in an animal's body to cause rapid bleeding.

The object of any hunting arrowhead design is to provide a structure which will cut a fairly large hole in the animal's body to cause rapid bleeding by the animal. Prior designs for accomplishing this have typically involved a structure having a multiplicity of parts or elements which must be affixed together in some manner. Of course, the greater the number of elements, the greater will be the manufacturing and assembling costs.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an arrowhead which will make a large cut in an animal's body to provide rapid bleeding.

It is also an object of the present invention to provide an arrowhead having few component parts and which may be easily fabricated.

It is still another object of the present invention to provide an arrowhead whose cutting edges yield little resistance upon penetration by the arrowhead in the body of an animal.

The above and other objects of the present invention are realized in an illustrative embodiment of an arrowhead which includes a generally longitudinal body section or portion, one end of which is pointed, and a pair of arcuate blades extending from either side of the body portion and each curving up and over a different face of the body portion. Each of the arcuate blades has a sharp leading edge extending from a corresponding side of the body portion upwardly and away from the pointed end to join a trailing edge which extends to and joins the rear end of the longitudinal portion. This arrowhead construction enables penetration of the arrowhead in an animal's body and yet provides a fairly large cut to cause rapid bleeding.

FIG. 1 shows a perspective view of one illustrative embodiment of an arrowhead made in accordance with the principles of the present invention;

FIG. 2 shows a side elevational view of the arrowhead of FIG. 1;

FIG. 3 shows a top plan view of the arrowhead of FIG. 1;

FIG. 4 shows a rear end view of the arrowhead; and

FIG. 5 shows one element which could be used in the fabrication of the arrowhead of FIGS. 1-4.

DETAILED DESCRIPTION

Referring now to the drawings, there is shown an arrowhead having a generally elongated or longitudinal body portion or section 2 composed of separate elements 3 and 4 secured together in a laminated fashion. The elements 3 and 4 may be secured together in any suitable manner including spot welding if the elements 3 and 4 are constructed of material which may be welded. One end of the body portion 2 is tapered to form a point 6 and the other end is formed into a blunt square 10. The two elements 3 and 4 are formed to define a hollow or socket 12 therebetween for receiving an arrow shaft. Edges 14 and 18 of the pointed end or front end of the body portion 2 are sharpened. A pair of arcuate blades 20 and 24 are integrally formed with elements 4 and 3 respectively and extend from either side of the body portion 2 to curve up and over a corresponding face of the body portion as shown in the drawings. Arcuate blade 20 curves up and over the top face of the body portion 2 in a generally semicircular fashion as best seen in FIG. 4, and arcuate blade 24 is formed in the same manner with respect to the bottom face of the body portion 2.

Each of the arcuate blades 20 and 24 have sharp leading edges 32 and 36 respectively which extend from corresponding sides of the body portion 2 outwardly and toward the rear end of the body portion where they join corresponding trailing edges 40 and 44. The trailing edges 40 and 44, in turn, extend to and join the rear end 10 of the body portion 2. In the embodiment shown in the drawings, the trailing edges 40 and 44 of the arcuate blades 20 and 24 together with the rear end 10 of the body portion 2 define a substantially flat plane.

A pair of triangular blades 50 and 54, cut from corresponding ones of the arcuate blades 20 and 24, extend from either side of the body portion 2. The triangular blade 50, which is cut from the arcuate blade 24 to thereby leave an opening therein, extends at substantially a right angle to the plane of the body portion 2 in a direction generally opposite that of the arcuate member 24. Similarly, the triangular blade 54, which is cut from the arcuate blade 20, extends from the other side of the body portion 2 at substantially a right angle to the plane of the body portion in a direction generally opposite that in which the arcuate member 20 extends. Each of the triangular members 50 and 54 has a sharp leading edge extending upwardly from a corresponding side of the body portion 2 and toward the rear end thereof to join with a corresponding trailing edge which extends back to and joins the corresponding side of the body portion.

Each of the arcuate blades 20 and 24 curve up and over a corresponding face of the body portion 2 and through a locus of points rearwardly of a corresponding one of the triangular blades 50. Thus, arcuate blade 20 curves to a point behind triangular blade 50, as best shown in FIG. 4, whereas arcuate blade 24 curves through a locus of points behind triangular blade 54. With this construction, an arrowhead entering the body of an animal will form a large closed cut of a configuration similar to the end profile of the arrowhead shown in FIG. 4. Little resistance would be presented to the arrowhead entering the animal in view of the sharpness of the edges 14 and 18 of the pointed end of the body portion 2 and of the leading edges of the arcuate blades 20 and 24 and the triangular blades 50 and 54. The size of the cut may be appreciated by comparing the end profile of the arrowhead with the diameter of the socket 12 which receives an arrow shaft. With a cut of the size indicated, a target animal should bleed rapidly eventuating early capture of the animal.

FIG. 5 shows element 3 of the arrowhead of FIGS. 1-4 prior to forming the arcuate blade 24 into the semicircular curve and the triangular blade 50 into a right angle extension from the plane of the body portion of the element 3. As shown, the body portion of the element 3 is formed to define a half socket 12a which, together with a half socket formed in element 4, forms the socket 12 for receiving an arrow shaft.

The arrowhead embodiment shown in FIGS. 1-4 is formed of two elements or pieces of material secured together as shown. This structure facilitates ease of fabricating the arrowhead. An alternative embodiment of the invention could include an arrowhead shaped like that shown in FIGS. 1-4 but fabricated from or cast into a single piece of material. This configuration would also facilitate ease of construction of the arrowhead.

It is to be understood that the above-described embodiments are only illustrative of the principles of the present invention. Other embodiments may be described by those skilled in the art without departing from the spirit and scope of the invention, and the appended claims are intended to cover such embodiments.
