6 Claims. (Cl. 43--6) This invention relates to an arrowhead, and more particularly has reference to an arrowhead having a retractable barb.

It is a highly desirable feature, in an arrowhead of the type used on arrows employed in the sport of shooting fish, that the arrowhead have a barb thereon, which barb prevents the fish from getting off after the arrow has penetrated its body. In this connection, when conventional arrows are employed, it is difficult to disengage the arrow from the fish, due to the presence of the barb, which interferes measurably with the movement of the arrow while it is being pulled back out of the fishs body. The arrow has a line attached to it, and when a nonretraetable barb is provided, the only way in which the arrowhead can be withdrawn is to cut the line.

In view of the above, the present invention is so designed as to have incorporated therein a barb that can be clipped in a position in which it is confined wholly within the arrowhead, preliminary to withdrawing of the arrowhead from the fish. With the barb confined within the arrowhead, the arrowhead can be easily withdrawn without the necessity of cutting the line.

An object of importance is to provide an improved construction for an arrowhead of the type stated, which will make use of a tubular housing adapted to be fitted onto the shaft of the arrow, with said housing being so designed as to simplify assembly to a distinct degree, and, further, to prevent the barb from bending back when the fish is caught.

Yet another object is to embody, in the tubular housing at least one slot through which a leg of the coil spring barb may be normally spring biased in an outward direction to an operative position, with said slot having at one end an overhang adapted for releasable engagement of the free end of said leg thereunder when the barb is to be clipped in a retracted position for withdrawing of the arrowhead;

Other objects will appear from the following description, the claims appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, in which:

Figure 1 is a side elevational View of an arrowhead formed in' accordance with the present invention, the barb being in a clipped or recessed position;

Figure 2 is'an'enlarged top plan view of the arrowhead;

Figure 3 is a longitudinal sectional view taken on line 3- 3 of Figure 2;

Figure 4 is a transverse sectional view, still further enlarged, on line 44 of Figure'3; and

Figure 5 is a transverse sectional view, taken on the same scale as Figure 4, on line 55 of Figure 3.

The reference numeral has been applied generally to an arrowhead formed in accordance with the present invention. The arrowhead 10, as shown in Figure 1, is adapted to be mounted upon a conventional arrow shaft 11 being engaged at the one end 12 of an elongated, cylindrical, tubular housing or sleeve 14 of the arrowhead 2,725,656 Patented Dec. 6 1955 The sleeve or housing .14 is open at its leading end 15 as well as at the trailing end 12. I I,

Disposed within the housing or sleeve 14 is a cylindrical, solid body 16 the forward end 18 of which is tapered to a point 20 with the face portion of the forward end 18 having a circumferential groove 22 formed therein to define a shoulder between the pointed forward end 18 and the other portion of the body 16. The pointed forward end of the body 16 projects longitudinally outwardly from the leading end 15 of the housing 14.

At its rear end, the body 16 has a flat end surface 24 formed with a central indentation 25 disposed inwardly from the trailing end 12 of the housing 14 so as to define with that portion of the housing extending to the end of the body remote from the pointed end thereof, a shaft-receiving socket 26 in which the shaft 11 may be engaged with the end surface of the shaft abutting the end face or surface 24 of the body and against the central indentation 25.

The body 16 is secured within the housing 14, in the position as hereinbefore set forth, by crimping the leading end 15 of the housing in the circumferential groove 22 so as to abut against the shoulder defined thereby, and a circumferential, knurled groove 28 in the housing 14 adjacent the end surface 24 of the body. 'As clearly shown in Figure 3, when the knurled groove 28 is pressed or otherwise formed in the housing 14, a portion of the material of the housing will engage in an annular external depression, of flat arcuate shape, formed in the body, as indicated at 31). Thus, the body 16 will be fixedly secured within the housing 14.

A diametrically extending, relatively wide slot or opening 31 is formed in the body 16 adjacent the shoulder portion or base of the pointed forward end 13. Engaged in the slot 31 against movement either longitudinally or transverseiy of the body 16 is a single coil spring 32, having an integrally-formed bottom leg 34 engaged in a longitudinal recess 36 formed in the underside of the body 16. The leg 34 extends approximately half the length of the groove or recess 36 and is frictionally maintained therein between the body and the adjacent inner surface of the housing, and is materially shorter than an integrally formed upper leg 38 of the coil spring 32. The leg 38 may extend outwardly from the body 16 and through a slot 42 formed in the upper surface of the housing 14, as shown in broken lines in Figure 3. One end of the slot 42 terminates above the coil of the spring 32 disposed in the opening 31. The leg 38 is, therefore, spring biased upwardly and outwardly from the body to extend through theslot 42 and has its free end provided with a rearward taper to define a point 39 so that the leg 38 defines a barb. The body 16 is provided with a recessed portion 40 extending from the opening 31 toward the end surface 24 and terminating adjacent thereto with the recess 40 opening toward the slot 42.

The recessed portion 41) defines a flat surface which the leg 38, constituting a barb when the device is in use, extends longitudinally of for the greatest part of its length and is retained against the bias of the coil portion of the spring 32 by engagement under an overhanging portion 44 formed on the housing 14 adjacent the end of the slot 42 remote from the leading end 15 of the housing, the overhanging portion 44 being approximately half the width of the slot 42 and thus, the barb 38 may be clipped or held in a retracted position. The operative position of the barb 38 is shown in broken lines in Figure 3.

In assembling the device, it is merely necessary to insert the body 16 with the coil spring positioned in the slot 31 in the rear, open end 12 of the housing 14 and then to push the same to a position wherein the base or shoulder of the forward pointed end 18 is at the leading end 15 of the housing. The leading end 15 of the housing may then be crimped into the circumferential, annular groove 22 and the knurled groove 28 cut into the housing so as to fixedly secure the body within the housing. The shaft 11 is then engaged fixedly in the provided recess 2e, and the arrow with'the arrowhead of this invention is now completely assembled.

In use, the leg 33is shifted to the dotted line position shown in Figured, said leg snapping to said position under the force of the spring tension in the coil 32. The arrow is then ready for use in shooting, and assuming that it has penetrated the body of a fish or other animal, with the head extending fully through the body, it can readily be withdrawn merely by clipping the leg 33 in retracted position as shown in Figures 1, 2 and 3 from the operative position shown in broken lines in Figure 3. To clip the leg, the free end portion is merely forced downwardly against the spring tension at the side of the overhanging portion 44, after which the leg 38 is shifted laterally to engage under the overhanging portion The arrow may then be withdrawn with ease and without further damage tothe body of the fish or other animal in which it is embedded.

From the foregoing, it will be apparent that there has been provided an arrowhead mountable on an arrow shaft which comprises a tubular housing 1 5 open at both the leading end and trailing end and 12 and having a longitudinal slot 42 formed therein, a body 16 having one end terminating in a point 18 carried within the housing with the pointed end 18 projecting longitudinally from the housing and having its other end spaced from the adjacent end 12 of the housing to define therewith a shaft-receiving socket, and spring means 32 carried by the body with a leg 38 on the spring means 32 biased radially outwardly from the body and through the slot 42 to define or form a barb. The housing 16 includes an overhanging portion 44 at one end of the slot 42 to releasably engage and hold the barb 38 against its spring bias.
