' nummc ARROW Filed May 24, 1954 J55. I I INVENTOR.

HUNTING ARROW William Norris, St. Marys, Ohio, assignor to Crown Controls Company, Inc., New Bremen, Ohio, a corporation of Ohio Application May 24, 1954, Serial No. 431,844

3 Claims. (Cl. 43-6) This invention relates to hunting arrows, and more particularly to the type of arrow which has a detachable arrowhead.

In bow and arrow fishing and hunting, when the arrow is fired and the arrow enters the fish or other game or prey, there is great danger of the arrow shaft being broken or lost during the thrashing efforts of the game to free itself.

One of the objects of the present invention is the production of a releasable arrowhead which will free the shaft from the thrashing and plunging of the game and isat the same time retrievable.

A further object of the invention is the provision of novel means for releasing the arrowhead from the shaft at the moment of impact with the body of the fish or other game so that, as the arrowhead enters further, the shaft is released from the head. i

A further object of the invention is the production of a hunting arrow, all parts of which are retrievable.

A further object of the invention is the provision of a buoyant shaft, which is made either of buoyant material or is made in the form of a hollow shaft of aluminum or other material not buoyant in itself but plugged at its ends to become buoyant in water.

Other objects and advantages reside in the construction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.

In the drawings,

Figure 1 is an exploded view of the parts of the arrow.

Figure 2 is a perspective view of the arrow showing the parts assembled and ready for use.

Figure 3 is a view of the releasable arrow, with the sleeve casing for the head shown in cross section.

Figure 4 is a view of a modified form of head or harpoon tip.

Figure 5 is an exploded view of the modification.

Referring more in detail to the drawing, an arrow or harpoon shaft is formed with feathers 12 and neck 14 for engaging the string of a bow. While specifically an arrow is shown for propulsion from a bow, it is to be understood that the invention is not limited to this specific form of shaft. Many such harpoons are thrown by hand or by some mechanical propelling means, or simply thrust and retained by the hand of the operator.

A cylindrical sleeve element 16 has permanent attachment to the forward end of the shaft 10. This sleeve is made of brass, stainless steel, aluminum, plastic, or other non-magnetic material. This sleeve may constitute the entire shaft of the arrow if it is made from some light weight metallic or plastic material. The shaft is buoyant. If it is made of non-buoyant material, then it becomes buoyant if made of hollow tubing with the ends stopped. In that event, tongues may be struck inwardly from the body of the sleeve to form a stop for the shank of the arrowhead.

In order to provide the necessary buoyancy, the ex- 5 aired States ate t 7, 2,796,691 Patented June 25, 1957 IQQ 2 treme end of the tubular sleeve is plugged or sealed and a suitable plug or seal is inserted at the end of the shank of the arrowhead.

The sleeve 16 is provided with cylindrical borings 18 and 20. The diameter of the boring 20 is less than that of the boring 18 so that an annular shoulder 22 is formed midway of the ends of the sleeve 16. The boring 18 receives and is permanently attached to the forward end of the shaft 10.

A permanent magnet 24 is seated upon the shoulder 22 and is permanently attached in any desired manner to the interior surface of the sleeve.

The forward portion of the sleeve is provided with an integral annular disc-like collar member 26. This member may be of any desired formation, such as protuberances bent back to form wings (not shown in the drawings) Its function is to provide a stop for the shaft when the arrow strikes the prey. An eye opening 28 is provided in the member 26 through which a retrieving cord may be threaded. The boring 20 has an outlet opening 30 for facilitating cleaning. The shank 32 of a ferromagnetic arrow 34 is received by the bore 20 and is seated on, and held by, the magnet 24. The arrow 34 is provided with a cylindrical opening 36 diametrically positioned in the shank 32 in an area adjacent the arrow head 38.

The end of a retrieving cord or cable 40 is passed through the opening 28 on the collar 26, and is then secured to the arrow shank at the opening 36. In operation, the arrow is placed within the forward end of the sleeve 16, and there held by the force of the magnet 24. The retrieving cord 40 is adjusted as described above and secured in a manner not shown, but commonly known to the art.

When the shaft is thrown or propelled by a bow, as the arrowhead 38 enters the fish or other game, the collar 26 strikes the body of the fish, stops the travel of the shaft. The arrowhead, under the impetus and momentum induced by the speed at which it is traveling, is freed from the magnet and continues into the body of the fish. The shaft 10 is freed and the danger of breaking due to the floundering and thrashing efforts of the prey to free itself is averted. The arrow 38 continues its travel into and is anchored in the body of the fish or other game.

The retrieving cord 40 is attached to the arrow and slides through the opening 28 in the collar which is attached to the shaft, so that both shaft and arrow are restored to the operator. The arrowhead and the cord remain attached to the body of the game and the cord is instrumental in bringing it in, as is well known in the art, particularly in harpoon fishing.

In the modification shown in Figures 4 and 5, the sleeve 42 is provided with a cylindrical boring 44 and the reduced boring 46. The boring 44 receives the end of the shaft 10, which can be in all respects the same as the shaft 10 shown in Figures 1, 2 and 3. A metal disc 48 lies against the shoulder 50 and operates to keep the bamboo or wood or other material of the sleeve from splintering under rigorous conditions of use. The boring 46 is provided with an opening 52 through the casing or sleeve 42 for purposes of cleaning and drainage. An annular collar 54 is attached to or formed integrally with the casing or sleeve 42 and operates as an abutment or stop which interrupts the flight of the shaft 10 when it strikes the body of the game and detaches it from the arrow 55.

The collar 54 is provided with an opening 56, through which the retrieving cable, such as the one shown at 40 in Figures 1 and 2, is drawn. It is also provided with a second opening 58.

The arrow 55 comprises the shank 60, the arrowhead or point 62, a tension spring or resilient member 64 and is sufiicient to disengage 'it and it is freed to-'continue-its travel into the body of the preyQp'Th'e barb enters the flesh and prevents accidental withdrawal of the'a'rrowhead. 7 I

Although the shaft has been shown as circular and the tubular portion and the shank also' as circular, lthese parts may have any othersuitable'cross sectional area,

such as square, rectangular, polygonal or oval-cross sectional.

' Although the preferred 'embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and modeof operation, which generally stated consist in a device capable of carrying out the objects setforth, as disclosed and defined in'the appended claims; 7
