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.

PNEUMOTHOROX-INDUCING HUNTING ARROW 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 US. 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 i 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 hollowtubular 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.

Theshaft 12 is provided withapertures 14 at closely spaced points and randomly orientated along theshaft 12. The spacing of theapertures 14 is preferably less than one-half inch between adjacent apertures. I have usedapertures 14 whose diameter is approximately l/16 inch. Stabilizers l6, l8 and 20 are fixedly secured to one end of theshaft 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.

Anadapter 24 partially enters and is affixed to the left-hand end of theshaft 12. Theadapter 24 hasholes 25 aligned with theapertures 14.Adapter 24 is hollow. Ahollow nock 22 is fixed to the exposed portion ofadapter 24. The outer diameter of theadapter 24 corresponds to the inner diameter ofshaft 12. Theneck 22 is recessed at 26 so that it may receive the bowstring. Thenock 22 is fixedly secured to theadapter 24 in any convenient manner such as by use of adhesives, crimping, etc.

The-right-hand end of theshaft 12 is connected to ahollow adapter 28. Theadapter 28 includes a reduceddiameter portion 30 which extends into theshaft 12 and aportion 32 hav ing an outer peripheral surface coextensive with theshaft 12. Fromportion 32, theadapter 28, has aconical portion 34 terminating in an 0 enend 35.

The adapter 8 IS physically connected to a portion of thearrowhead 38 which may be of the broad head type. Arrowhead 38 may be of the type having aconical tube 39 which telescopes overportion 34 and terminates in anotch 36 receiving the arrowhead blade. Arrowhead 38 is provided with an aperture 40 extending from a notch separating thearm portions 42 and 44.Arm portions 42 and 44 are spread apart so as to receive theconical tube 39 to which they are joined.Adapter 28 andarrowhead 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 reduceddiameter portion 30 is fixedly secured to theshaft 12 in any convenient manner such as by adhesives, crimping, etc. To facilitate such joining, theportion 30 is provided withperipheral notches 46. Theadapter 28 is hollow and provided with an axially disposedpassage 48 which communicates at one end with the interior of theshaft 12. Transversely extendingpassages 50 intersect thepassage 48 at spaced points along its length. Tube 39 hasapertures 37 aligned with thepassages 50 inadapter 38 and the space at itsend 35. As shown more clearly in FIG. 1, some of theapertures 37 are located within the aperture 40.

When in use, the arrow 10 is capable of inducing pneumothorax. That is, when thearrowhead 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 ofpassages 25, 50 and 48,apertures 37, the interior ofshaft 12, and one or more of thenumerous apertures 14 as well as thehollow 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.

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.
