3,014,305 ARROWHEAD FOR BOW FISHING Frank 3. Yurchich, 1024 E. Knapp St., Milwaukee, Wis.

Filed Mar. 30, 1959, Ser. No. 892,819

4 Claims. (Cl. 4 3-6) This invention relates generally to arrowheads used in shooting fish. Morespecifioally, this invention relates to an arrowhead having a retractable barb.

When shooting fish with bow and arrow, it is desirable to have an arrowhead that has means for preventing the fish from sliding off the arrow after it has been speared. In the past, most arrowheads of this type have come equipped with at least one outwardly extending barb. However, usually these barbs were set in an outwardly extending position prior to shooting the arrow. Such a construction makes it more difiicult for the arrow to penetrate the body of the fish. Furthermore, such an arrow is more likely to be deflected by the water than an arrow without the outstanding barbs, making it more difficult to hit the target.

Another problem encountered with arrowheads having barbs is the problem of withdrawing the arrow from the body of the fish. Various constructions have been proposed for solving this problem and most of them are directed to a means for inserting the barb Within a recess in the arrow housing prior to withdrawing the arrow.

The arrowhead of this invention overcomes the problems encountered with prior art arrowheads by calling for a set of outwardly extending barbs that are retained near the stem of the arrow while it is shot and until the arrow has passed through the body of the fish. At that time the barbs spread to prevent the fish from sliding off the arrowhead. The arrowhead of this-invention is provided further with a collar member retaining the barbs against the arrowhead so that it may be easily withdrawn from the body of the fish.

Therefore, it is the object of this invention to provide a new and improved arrowhead for bow fishing.

Another object of this invention is to provide a new and improved arrowhead having barbs that retained near the body of the arrow until the arrow has passed through the body of the fish.

Another object of this invention is to provide a new and improved arrowhead having barbs that can be retained adjacent the bow of the arrowhead so that the arrowhead may be easily withdrawn from the body of the fish.

Other objects and advantages of this invention will be apparent from the following description when read in connection with the attached drawings, in which:

FIG. 1 is a sectional view of the arrowhead of this invention with the barbs retained against the side of the arrowhead; and

FIG. 2 is a sectional view of the arrowhead of this invention in which the barbs are spread away from the shaft of the arrow.

As illustrated in the drawing, the arrowhead comprises a cylindrical hollow tube 11 having a pointed body member 12 extending longitudinally from one end thereof. The body member 12 is preferably of a solid hardened material and extends into the tube through only a portion of the length of the tube 11. The remainder of the tube 11 forms a receptacle for the forward end of an arrow shaft 14. The body member 12 is formed with a recessed portion 15 that coincides with the forward end of the tube 11. In assembly, the forward end of the tube is rolled into the recess 15 to mount the body member in the tube. Such a structure permits the heat treating of the point of the arrowhead prior to assembly.

Intermediate the ends of the tube are a pair of subretain the barbs near the shaft of the arrow.

3,014,305 Patented Dec. 26, 1961 2 stantially diametrically opposed apertures 17. The inner end of the member 12 has a projection shown as an eye 20 having a transverse hole 21 formed therein. In the preferred embodiment shown in the drawings, the distance between the recessed portion 15 of the body portion 12 and the hole 21 in the eye 20 is less than the distance between the end of the tube 11 and the op posed apertures 17 in the tube. Furthermore, the diameter of the projection 20 is considerably less than the internal diameter of said tube. In assembly the tube is moved over the arrowhead until the apertures 17 in the tube 11 are aligned with the transverse hole 21 in the eye 20. A wire 24 is then threaded through the apertures 17 and said hole 21. Then'the body member 12 is forced to move longitudinally relative to the tube 11 until the end of the tube is aligned with the recess 15 in the body member. In this position the hole 21 in the eye 20 is transversely out of line with the apertures 17. This forces the'wire 24 to take a stepped or wavelike formation within the tube causing the outer ends of the wire to spread outwardly to form barbs 25. The end of the tube is rolled into the recess to unite the body member 12 and the tube 11 and to maintain the barbs 25 in their outwardly projecting position. The wire which forms the barb is preferably spring wire so as to have a suitable amount of resilience which tends to keep the barbs in their outwardly extended position.

Suitable means are provided for retaining the free ends 26 of the barbs 25 adjacent the shaft of the arrow. As shown in the drawings, a collar 28 is slidably mounted on the shaft of the arrow for this purpose. One end of the collar 28 has a flange 29 to form with the shaft of the arrow an annular recess 30 for receiving the free ends of the barb. When the free end 26 ofthe barbs 25'are retained in the recess 30, the barbs assume a bowed position relative to the shaft and tube. To facilitate the retention of the barbs in their position adjacent the shaft, the endsi26 may be formed on an angle so that they are substantially parallel to the axis of the flange when in the bowed position. In this Way a greater portion of the barb contacts the flange on the collar, thereby insuring a firmer grip between the collar and the barb.

If desired, means may be provided to limit the axial movement of the collar 28. As shown in the drawings, a groove 34 is formed in the arrow for receiving a snap ring 33. The snap ring '33 serves to limit the axial movement of the collar relative to the shaft. As shown in the drawings, the other end 35 of the collar 28may also be enlarged to a size larger than the external diameter of the snap ring so as to more easily coact with the snap link. Although a snap ring has been shown, it will be obvious to those skilled in the art that other suitable stoppers may be used with the collar.

The end of the shaft 14 is forced into. the open end of the tube and secured therein by any of the means well known in the art. As shown in the drawings, the end of the shaft is merely press fitted into the hollow tube.

When the arrow has been assembled and is ready for use, the free ends 26 of the barbs 25. are pressed inwardly toward the shaft and the flange 29 of the collar is positioned over the free ends ofthe barbs to In this position as shown in FIG. 1, the barbs are bowed relative to the longitudinal axis of the shaft and tube. Since the barbs are spring members they engage the collar with considerablev force and are retained in the bowed position due to the friction between the barbs and the collar.

To facilitate the retention of the barbs in their position adjacent the shaft, the ends 26 may be formed on an angle so that they are substantially parallel to the axis of the flange when inthe bowed position. In this way a greater portion of the barb contacts the flange on the collar, thereby insuring a firmer grip between the This is actually done by the body of the fish which engages the collar as the arrow is passing therethrough. After the arrow has passed through the body of the fish, the barbs will spring back into their outwardly projecting position such as shown in FIG. 2. In this position it is impossible for the body of the fish to slide oh the arrowhead.

When it is desired to remove the arrowhead from the body of the fish, the barbs are again forced inward toward the shaft and the collar is positioned over the ends of the barb. The entire arrow and arrowhead may then be easily retracted from the body of the fish. To facilitate removal of the arrowhead, the outer surface of the other end 35 of the collar member may be slightly tapered.

Although but one embodiment has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made in the disclosed arrowhead without departing from the spirit of the invention or from the scope of the appended claims. I

What is claimed is:

1. An arrowhead mountable on an arrow shaft comprising a tube open at both ends, a body having one end the pointed end extending longitudinally therefrom, the other end of said tube being adapted to receive the shaft of an arrow, a wire engaging said tube and forming a pair of outwardly and rearwardly extending barbs, and tubular means adapted to be slidably mounted on the arrow shaft for retaining the ends of said barbs adjacent said shaft in such a manner that the ends of said barbs exert an outward force on said collar and the barbs bow outward intermediate their ends, whereby when passing through a body the natural inward pressure of the body on said bowed portion causes said barb to release the force on said collar so that it may slide freely.

2. An arrowhead mountable on an arrow shaft comprising a tube open at both ends and having a pair of opposed apertures intermediate the ends of said tube, a body having one end terminating in a point mounted within tube with the pointed end extending longitudinally therefrom, the other end of said body terminating in an eye portion for receiving a barb, a wire threaded through said apertures and said eye and being formed into a pair of barbs extending rearwardly and outwardly in their normal position, and tubular means adapted to be slidably mounted on the arrow shaft for retaining the ends of the barbs adjacent the shaft in a stressed condition, said barbs being bowed outwardly beyond said tube when their ends are forceably engaging said tubular retaining means, whereby when said arrow passes through a body the natural inward pressure of the body on the bowed portions of said barbs forces said barbs inward in such a manner as to release the ends of the barbs from said tubular retaining means so that said tubular retaining means can slide freely on said shaft out of engagement with said end of said barbs. V

3. The arrowhead of claim 2 in which the eye portion and said apertures are transversely out of line so that the ends of a wire threaded through the eye and said aperture extend outwardly and rearwardly of said point in their natural position.

4. An arrow comprising a shaft, a tube open at both ends, a body having one end terminating in a point mounted within said tube with the pointed end extending longitudinally therefrom, said shaft being mounted in the other end of said tube, a wire engaging said tube and having a pair of outwardly and rearwardly extending barbs, and a collar slidably mounted on said shaft for terminating in a point mounted within said tube with engaging the ends of said barbs and retaining them adjacent said shaft in such a manner that they form a bow intermediate their ends and exert an outward pressure on said collar to retard its axial movement, whereby when passing through a body the natural inward pressure of the body on the bowed portions of the barbs causes said barbs to release said collar so that it can slide freely on said shaft.
