Description:

My invention relates to arrows, and the principal object is to provide an arrow that will permit of its head being easily removed and replaced.

The distinct advantage of my invention is that when an archer becomes accustomed to a certain arrow and can shoot same accurately, he may nevertheless use the same shaft with a plurality of arrowheads that afford the same balance for the arrow. This may be obtained by having the 1 different heads of the same weight (even though they vary in shape), or in certain cases the weight may be somewhat different, providing the balance of the arrow is not disturbed. Thus an archer may obtain the same accuracy and approximately the same distance irrespective of the type or shape of head. However, heavier or lighter arrowheads or tips may be used for special purposes.

Another object is to be able to provide different arrowheads for different types of hunting, or to provide a head merely for target practice.

The invention also comprises novel details of construction and novet combinations and arrangements of parts, which will more fully appear in the course of the following description.

However, the drawing merely shows and the following description merely describes an embodi-ment of the present invention, which is given by way of illustration or example only.

In the drawing, like reference characters designate similar parts in the several views.

Figure 1 is a broken elevation, partly in section, showing a form of my invention.

Figure 2 is an end elevation, looking in the direction of the arrow A of Figure 1.

Figures 3, 4 and 5 are elevations of other embodiments, showing the shafts broken away.

Figure 6 is a section taken on the line 6-6 of either Figure 4 or Figure 5.

Figure 7 is a broken elevation, partly in section, of still another form of the invention.

Figure 8 is a broken side elevation, looking in the direction of the arrow B of Figure 7.

Figures 9 and 10 show modified forms of shafts in section and modified forms of arrowheads in elevation.

Figure 11 is a disassembled view, partly in section, of the form shown in Figure 3, taken in the direction of the arrow D.

Figure 12 is a modified form of tip that may be used on the arrow shown in Figure 7.

Referring more in detail to the drawing, th reference number 14 designates a wooden shaf of an arrow. The usual feathers and rea notched end for the shaft are not shown since they are well known to those skilled in the art.

The forward end of the shaft 14 is tapered, as shown at 15, and is received in the interiorly tapered end 16 of a ferrule 17. A pin 18 fastens the ferrule 17 on the tapered end 16. The ferrule has a tapped end 19. The ferrule is tapered exteriorly in order to permit a greater thickness of the shaft at the point C, which is the point 0 of greatest stress between the shaft and the ferrule.

The drawing shows several forms of arrowheads, but it is to be understood that other forms may also be used. Those shown are by way of illustration only.

The form of arrowhead shown in Figures 1 and 2 is for hunting birds. This form comprises a shank 20 which is drilled for reception of a series of rods 21 that are radially disposed with respect 20 to the axis of the shank. A conical or pointed tip 22 streamlines the front of the arrow. The shank has a threaded stud 23 projecting rearward, for screwing into the tapped opening 19, to attach the arrowhead to the shaft 14, through 25 the intermediary of the ferrule Ii.

This arrowhead is for shooting birds. The spread of the rods 21 may be likened to a spray of shot from a shotgun, since this arrowhead covers a considerably wider area than the mere di3ameter of the shaft. This point is primarily intended to strike and stun a bird, whereby it may be captured.

The rods 21 have a friction-type fit in the shank 20, but are removable, in order to replace them when they become broken or bent beyond repair. The rods 21 are preferably spring steel.

By reason of their comparatively small diameter, they offer very small resistance to the flight of the arrow. The streamlined tip 22 of course aids 40 in cutting down wind resistance and directing the flight of the arrow.

For hunting game, such as deer, etc., a tip 24 having a blade 25 may be used. Of course different sizes of blades may be used for different 45 purposes. As best shown in Figure 11, the tip 24 is slotted, as shown at 26, and the blade is inserted in the slot. The blade 25 is sweat soldered, or otherwisefastened in the slot 26. Thus when the blade 25 becomes broken, it may be easily Sremoved by heating the tip 24 and melting the 50 solder. The blade 25 may of course be made replaceable by other fastening means.

The blade 25 has tail members 21 that extend t rearwardly with regard to the body of the blade. r r These tail members bear against the side of the ferrule 17 to reenforce and strengthen the bad edges of the blade. This arrangement also in. sures greater accuracy in assembling the blade in the slot 26.

The blade 25 may be assembled in the slot sc that it is removable without heat, so that if the blade gets stuck in an animal or object, the shaft and tip (without the blade) may be withdrawn.

An arrowhead 28, such as shown in Figure 4, is ordinarily used for target practice and other uses. It has a pointed tip 29 and is knurled, as suggested at 30, to facilitate unscrewing the tip as is the head 24 of Figures 3 and 11, to faciliitate removal thereof in the event of detachment of the blade 25.

The arrowhead 31, as shown in Figure 5, has a blunt end 32. This head may be used for hunting rabbits and other game. This head 31 is approximately the same weight as the target head 28, so that when an archer becomes accustomed to the target head, he will get the same accuracy with the blunt head 31.

Figure 7 shows a shaft 33 provided with a notch 34 at its rear end, but it will be noticed that this shaft is not feathered, since it is to be used in water for shooting fish. The shaft 33 has a tapered end 35 which has a slot 36 at the side of the tapered end 35. A fish arrowhead 37 has a body 38 slotted at 39 in which swing barbs 40. The barbs are pivoted on the pin 41 and have shoulders 42 that engage the end of the slot 39, to limit outward movement of the barbs 40. The opposite end 43 of the slot 39 limit the inward movement of the barbs 40, as shown by the dotted lines in Figure 7.

The rear end of the body 38 has a flaring ferrule 44 which receives the tapered end 35 of the shaft 33. The portion 45 of the body 38, which is between the slot 39 and ferrule 44, has a bore 46 through which is normally passed a 4 fish-line 47. A knot 48 at the end of the line prevents the line from being pulled through the bore 46. A double clove hitch 49 is caught around the shaft 33 and a loose loop 50 connects the clove hitch with the knot 48. 4 The forward end of the body 38 is tapped, as shown at 51, to receive a threaded stud 52 on the end of a tapered point 53 that carries a blade 54. The blade 54 is preferably of substantially the same width as the aggregate width 5( of the barbs when they are in their closed (dotted line) position.

Figure 12 shows a point 55 which may be substituted for the point 53 and its blade 54. The blade 54 is used where it is desired to cut an incision so the barbs 40 may enter the fish's body, such as in the case of a fish having a tough skin.

The pointed tip 55 reduces water resistance and is sufficient to enter the body of a fish having skins whose consistency is less tough. In the use of the fish head, the arrow is shot from a bow with the parts substantially as shown in Figure 7, but with the barbs in their closed position. Then when the blade 54 and barbs 40 enter the fish, the barbs swing outward when the archer tends to pull back on the line 47. This pull on the line draws the shaft 33 out of the tapered ferrule 44, so that the shaft k will not be broken in the subsequent fight of the fish. The head, barbs, blade and point act as a harpoon and by means of such parts the fish is landed.

i 5 In Figure 9 a hollow metal shaft 56 has a threaded thimble 57 inserted in an open end of the shaft. The thimble is interiorly threaded to receive a threaded stud 58 on the arrowhead 28.

In Figure 10 a solid metallic shaft 59 is tapped at an end 60 to receive a threaded stud 58 on the head 28.

The use of all of the forms of my invention is believed clear since each of them is shot from a conventional bow in a conventional manner, and the particular operation and use of each form has been hereinbefore described in connection with the description of each form. It is to be understood that other connecting means may be used instead of the screw threaded connection, by which I provide interchangeability for different arrowheads.

While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of construction illustrated and described, but desired to avail myself of all modifications which may fall within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: 1. An arrow comprising a shaft, a ferrule of the same diameter as the shaft fixed at one end around an end portion of the shaft and having a threaded socket beyond the shaft end, a head having a portion of the same diameter as the :o shaft and ferrule, abutting the outer end of the ferrule and provided with a threaded extension within the threaded socket of the ferrule, said head having an endwise slotted tip, and a blade seated in the slot of the tip and having tail por5 tions extending rearwardly along, and against, diametrically opposite points of the ferrule.

2. An arrow comprising a shaft, a removable tip having a threaded connection with the shaft, and a blade relatively fixed on the tip for ordinary archery purposes, the blade having tail members extending rearwardly with respect to the tip and engaging the opposite sides of the shaft for reinforcing the blade in its position and substantially to prevent rocking of the blade in opposite directions on the tip.

3. An arrow comprising a shaft, a removable tip having a threaded connection with the shaft, the shaft and tip having abutting faces limiting inward screwing of said threaded connection, and a blade relatively fixed on the tip for ordinary archery purposes, the blade having tail members extending rearwardly of the said abutting faces and engaging the opposite sides of the shaft for reinforcing the blade in its position and substantially to prevent rocking of the blade in opposite directions on the tip.
