Pneumothorox-inducing Hunting Arrow

Abstract

A hunting arrow is provided with a hollow shaft perforated along its length. An adapter is connected to the forward end of the shaft and has a longitudinal passage in communication with the hollow shaft, and transverse passages communicating to the atmosphere. An arrowhead is fitted over the adapter with the transverse passages of the adapter being disposed between the ends of the blades of the arrowhead. Where the ferrule overlies the transverse passages, it is formed with openings.

Description

The present invention is directed to a hunting arrow, and more particularly, to a hunting arrow which is open at both ends so as to facilitate introducing air into the cavity induced into an animal struck by the arrow. The arrow of the present invention is predicated on the phenomenon known as pneumothorax wherein the introduction of air into a cavity in the chest wall of an animal results in the collapse of the lungs.

The hunting arrow of the present invention has an arrowhead or other pointed object at one end and feathers at the opposite end. The shaft of the arrow is hollow and provided with holes randomly distributed throughout its length. Each end of the hollow shaft is open to the atmosphere as compared with U.S. Pat. No. 2,554,012, the closest patent known to me, which is closed at both ends. At the arrowhead end of the shaft, the opening which communicates with the interior of the shaft is disposed at a location intermediate the ends of the arrowhead.

It is an object of the present invention to provide a novel arrow constructed in a manner so as to cause pneumothorax.

It is another object of the present invention to provide a novel hunting arrow which is open at both ends.

It is another object of the present invention to provide a hunting arrow which is capable of being manufactured at a minimum cost while being simple, reliable, and capable of introducing air into the cavity induced in the chest wall of an animal.

Other objects will appear hereinafter.

For the purpose of illustrating the invention, there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIG. 1 is a side elevation view of the arrow in accordance with the present invention.

FIG. 2 is a sectional view taken along the lime 2--2 in FIG. 1. FIG. 3 is a sectional view taken along the line 3--3 in FIG. 1.

FIG. 4 is a sectional view taken along the line 4--4 in FIG. 1.

FIG. 5 is an enlarged detail view of a section of the shaft.

Referring to the drawing in detail, wherein like numerals indicate like elements, there is shown in FIG. 1 a hunting arrow designated generally as 10. The arrow 10 has a hollow tubular shaft 12 made from tubular material cut to unit lengths. The shaft is preferably 27 to 33 inches long and made from commercially available fiber glass tubes. Other materials such as hollow wooden shafts or hollow plastic shafts may be used.

The shaft 12 is provided with apertures 14 at closely spaced points and randomly orientated along the shaft 12. The spacing of the apertures 14 is preferably less than one-half inch between adjacent apertures. I have used apertures 14 whose diameter is approximately 1/16 inch. Stabilizers 16, 18 and 20 are fixedly secured to one end of the shaft 12 in any convenient manner such as by the use of adhesives and epoxy resins. The stabilizers may be made from desirable material such as feathers, plastic, paper, etc. While three such stabilizers are illustrated, a greater or lesser number of stabilizers may be utilized.

An adapter 24 partially enters and is affixed to the left-hand end of the shaft 12. The adapter 24 has holes 25 aligned with the apertures 14. Adapter 24 is hollow. A hollow nock 22 is fixed to the exposed portion of adapter 24. The outer diameter of the adapter 24 corresponds to the inner diameter of shaft 12. The nock 22 is recessed at 26 so that it may receive the bowstring. The nock 22 is fixedly secured to the adapter 24 in any convenient manner such as by use of adhesives, crimping, etc.

The right-hand end of the shaft 12 is connected to a hollow adapter 28. The adapter 28 includes a reduced diameter portion 30 which extends into the shaft 12 and a portion 32 having an outer peripheral surface coextensive with the shaft 12. From portion 32, the adapter 28, has a conical portion 34 terminating in an open end 35.

The adapter 28 is physically connected to a portion of the arrowhead 38 which may be of the broad head type. Arrowhead 38 may be of the type having a conical tube 39 which telescopes over portion 34 and terminates in a notch 36 receiving the arrowhead blade. Arrowhead 38 is provided with an aperture 40 extending from a notch separating the arm portions 42 and 44. Arm portions 42 and 44 are spread apart so as to receive the conical tube 39 to which they are joined. Adapter 28 and arrowhead 38 may be made from any convenient metal and physically joined together in any one of a wide variety of manners including riveting, welding, adhesives, etc.

The reduced diameter portion 30 is fixedly secured to the shaft 12 in any convenient manner such as by adhesives, crimping, etc. To facilitate such joining, the portion 30 is provided with peripheral notches 46. The adapter 28 is hollow and provided with an axially disposed passage 48 which communicates at one end with the interior of the shaft 12. Transversely extending passages 50 intersect the passage 48 at spaced points along its length. Tube 39 has apertures 37 aligned with the passages 50 in adapter 38 and the space at its end 35. As shown more clearly in FIG. 1, some of the apertures 37 are located within the aperture 40.

When in use, the arrow 10 is capable of inducing pneumothorax. That is, when the arrowhead 38 pierces the thoracic wall of an animal, the cavity created by the arrowhead or the shaft depending on depth of penetration will be directly in communication with the atmosphere by way of passages 25, 50 and 48, apertures 37, the interior of shaft 12, and one or more of the numerous apertures 14 as well as the hollow nock 22.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.

Claims

It is claimed:

1. In a hunting arrow comprising a hollow shaft perforated along its length, an adapter axially connected to one end of said shaft and projecting forwardly of the shaft, an arrowhead blade connected to said adapter, said adapter having a longitudinally extending passage axially disposed with respect to said shaft providing communication between the atmosphere adjacent the forwardly projecting portion of said adapter and the interior of said shaft by way of a transversely disposed passage, said transversely disposed passage being intermediate the length of the arrowhead blade and said blade being connected to a conical tube telescoped over the forwardly projecting portion of the adapter, said tube having an aperture aligned with the transversely disposed passage.
