INTERLOCKED MULTIPLATE ARROWHEAD CONSTRUCTION Filed Dec. 15, 1947 3 Sheets-Sheet 3 88 IN VENT OR.

Jzmes Ramsgy ATTDRN EYS Patented Apr. 17, 1951 UNITED STATES PATENT OFFECE INTERLOCKED MULTIPLATE ARROWHEAD CONSTRUCTION 8 Claims.

This invention relates to improvements in arrow heads which are adapted for use with arrows that are propelled through the air by a bow and reference is hereby made to my previously co-pending application, Serial No. 37,610, now U. S. Patent No. 2,504,449, granted April 18, 1950.

An object of the invention is to provide a sectional arrow head having a unique retaining means incorporated therein, by which means the arrow head is retained on the forward or ferrule end of an arrow shaft.

Another object of the invention is to provide a sectional arrow head whose sections may be either left flat to form the less preferred twoedged form of arrow head, or be bent outwardly in angular relation to each other to form the preferred form of arrow head with four cutting edges, or one with three cutting edges, or with six cutting edges, since actual tests in hunting have proven that a strong, well formed arrow head with three or more cutting edges is superior to the ordinary two-edged arrow head as a big game killer, because the pattern of the wound it makes allows the arrow shaft to enter more readily without binding, thereby increasing penetration, which allows more Veins and arteries to be severed; and such a wound sags open, causing a much greater hemorrhage internally, as well as spilling more blood externally, which makes trailing wounded game easier.

A further object of the invention is to provide a sectional arrow head having unique retaining means therefor that are so arranged that the arrow head sections are retained as a fixed unit without the disadvantage of having protuberances or spaces formed in the arrow head that will retard penetration of the arrow into toughskinned big game animals, or that will tend to collect foreign matter that would unbalance the arrow head.

A still further object of the invention is to provide a strong sectional arrow head having a unique latching means incorporated therein by which means the sections are retained firmly in face to face engagement with each other so that the point of the arrow head will not curl or bend, or the sections come apart upon the head striking a large bone or other hard substance.

With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully herinafter described, claimed and illustrated in the accompanying drawings in which:

Referring more in detail to the drawings, and

sections of especially to Fi ures 1 to 4, inclusive, there areshown two similarly shaped blanks 32 and 36' respectively that are oo-operatively assembled after forming to provide an arrow head embody ing the invention, especially the preferred form ever, since the arrow heads embodying this invention may be either barbedor unbarbed at the base, and unbarbed heads are usually preferable, since the hunting laws of many of the states prohibit'the use of barbed heads in hunt.

ing, the blanks may vary somewhat from the triangular shape shown. The sharp corners where the cutting edges and the base meet may be rounded off; or cut away to form unbarbed blades, or thetbase of each blank'may be so cut as to form barbs. The blanks have cutting edges. 3| terminating in a point 32, and the cutting edges may be of any configuration suitable for the purpose for which they are to be used; The blanks may be wide or narrow, long or short, or a variation of either, and the point 32 may be of any shape desired for the .purpose to which it may be put.

When the blanks are stamped, cutouts 83 and 33 are formed in the blanks and the material left over by the cutouts is bent at right angles to the surface of the blanks'to form, flanges 34.

The cutouts are so spaced along the vertical center of the blanks that the flanges 3-! of the cutouts 33' will interfit within the cutouts 33,

- 4 and vice versa the flanges 34 of the cutouts 33 will intel'fit with the cutouts 33.

The portion ofthe blanks lying between the cutouts will be referred to as bands 35 and their purpose will be later described. Above the uppermost cutout 33 in the blank 33, there is provided a slot 36 which forms the band 3'! above the uppermost cutout 33.

A cutout 38, adjacent the point 32 of the blank 35' forms a tongue 39 which, extending at right angles from. the blank, interfits with a cutout Gil formed in the blank 39'. The cutout 40 forms the keeper or lip ll for a purpose to be later described.

In Figures 5 to 8, inclusive, the blades have been formed for assembly together, but have not been bent to form the preferred form of arrow head with four cutting edges, as shown by Figures 21 and 22. They have been left unbent to show how they look when assembled together in flat inner face relation to each other, to be later applied to an arrow shaft 42, as in Figure 9, in which less preferred form of arrow head they be used for small game hunting and practlce shootin and in this form, will be referred to as blades 32 and 3% respectively.

When this preferred form of the two blanks is used'to make the preferred form of arrow head with four cutting edges, as shown in Figures 21 and 22, or any of the modified forms of arrow heads in which they may be used, they and their various parts assume the numerals used to indicate them in the figures illustrating said succeeding forms.

The edges 35 have been formed but these are simply blunt edges, not yet having been sharpened and'fashioned into actual cutting edges, as

the actual cutting edges may be of any configuration which is suitable for the purpose for which they are to be used. The bands 35 and 3'! have been curved inwardly to fit through corresponding cutouts in the mating blank as the two sections are fitted together, and the flanges 5% have been turned as shown in Figure 5A.

The band 43 of the blade 36 is' formed by the material of the blade, outwardly of the slot 36, and this band is bent outwardly of the blade 30. The band M formed on the blade til outwardly of the uppermost cutout 33 is also bent outwardly of the blade 30 in opposed relation to the band 53. The purpose of the band 43 and the band 44 is to provide an even brim for the arrowhead socket, so that the base of the finished arrow head will be evenly balanced and, have an even appearance.

The blades, eitherbent to provide the preferred form of arrow head with four cutting edges shown in Figures 21 and 22, or one of the modified forms with three, or four, or six cutting edges, or else left flat in the less preferred forms shown in Figures 9 and 13, are assembled in inner face relation to each other and held clamped tightly together, preferably in some sort of a proper arrow head forming machine or device. A strong metal core or shaft, which may be a part of the device, the end of which is conical in formation and of exactly the same shape and size as the arrow shaft 42 that the head is intended to be later applied to, is forced down into the socket formed by the bands 35, 3?, 43 and M to mold to perfect shape and bind the blades in the closest possible engagement with each other. Since the intended arrow shaft 42 will extend to terminate within the last band on each section, this metal internal socket forming core will like- '5 wise extend in that far during the process of making the arrow head.

The tongue 39 having entered and extended through the cutout 40 as the blades were assembled together is now bent over, the tip rearwardlyof the blade, to mesh with lip 41 to bind the points 32 firmly together and form a smooth surface on both sides of the blades.

The flanges 34 are then bent upward into contact with the metal internal socket forming shaft and shaped thereto, as in Figures 9, 13, 20, 22 and 24, wherein a wooden arrow shaft 42 has been fitted into the finished socket after the removal of the metal forming shaft. 4

Thus a smooth exterior surface is formed on the socket wall that will not catch or drag and retard penetration of the arrow into animal tissue, or collect foreign matter that would tend to unbalance the arrow head.

The two blades are not welded securely together at all places where they fit face to face against each other, especially along the line of contact from the very tip of the point 32 up to the fore end of the socket, tongues and lips being welded together the same as the rest, to make it a stronger, more rigid, more efficient arrow head.

A regular metal arrow pile or ferrule, such as are used on the fore end of arrow shafts may, if desired, be fitted into the socket formed by the bands and flanges and welded or soldered in place, to make it even a more stronger arrow head.

The entire arrow head may now be solderdipped, or otherwise similarly treated to give it a better appearance.

The completed arrow head is now ready to be applied to an arrow shaft 42 when desired. The arrow head may be fixed on the arrow shaft 42 by a small pin 45 driven through a small hole in one of the rearmost bands of the arrow head.

It is not the purpose of the arrow shaft 42 to hold the blades together in any of the forms of this invention. The tongues and the welding and soldering are supposed to do the holding of the blades together. But in case the welding and tongue should burst loose upon impact of the arrow head against some solid object, the wedging tendency of the arrow shaft in the socket will still bind the blades together.

In Figures 10 to 12, inclusive, the blades 30 and 30 are similiar in shape, having the cutting edges 38 and point 32. However, the bands 46 formed by the cutouts 4'! and 4? respectively do not have flanges formed thereon as previously described.

These bands are all bent inwardly of the inner face of the blades while the band 48 on the blade 30 and the band 49 on the blade 30 are bent outwardly of the outer face of the blades in opposed relation to each other. With the exception of flanges these blades are assembled together and formed into finished arrow heads with two, three, four or six cutting edges just as were the form of blades previously described.

The two blades formed into the arrow head shown in Figures 13 to 15 inclusive is somewhat different in formation.

The blades 50 and 50' respectively having edges 5| and points 52 are placed in contact with each other so that one edge of each overlaps one edge of the other, as shown in Figure 15. The edge thatextends out beyond the other becomes the actual cutting edge, and may be of any configuration desired for the purpose, and may be sharpened so as to provide the proper efficiency. The

edge that lies more inward serves as a brace or '6 stiffener, to make the arrow head more rigid. Thus only one edge of each blade is actually a cutting edge in this arrow head.

The bands 52, formed by cutous 53, have flanges 54 formed thereon so that the flanges contact the arrow shaft 42, when it is later fitted into the socket of the finished arrow head, to form a smooth exterior surface on the outer faces of the blades, These bands extend inwardly while the top bands 55 of each blade extend in the opposite direction. A pin 56 driven through a small hole in one of the top bands 55 secures the finished arrow head on the shaft 42.

This form of the invention uses a plurality of spaced tongues 51 entering the cutouts 58 to have the lip 59 pressed therein to form a smooth surface.

This form of the invention provides a stiff, rigid, strongly-made two edged arrow head suitable for hunting big game, and is the preferred form of the flat, two-edged arrow head forms, the less preferred forms being those shown in Figures 9 and 12.

In Figures 16 and 17, the blades as and Bil are similar to blades 58 and till having bands 6| formed by cutouts 62, but these bands have no flanges thereon as in Figures 13 to 15, inclusive. The top bands 53, in like manner, extend in the opposite direction, similar to the previous forms described. Tongue Ed entering cutout 55, is depressed together with the lip 66 to form a smooth surface.

In Figure 18, the bands 6'! of both blades 68 and 68 respectively all extend in the same di rection, and are formed in the same manner, as

previously described. The two blanks of this form are the simplest and easiest of all the forms to make, and can be used for a two-edged arrow head, or for one having three cutting edges, or four cutting edges, or six cutting edges.

The form of the invention shown in Figures 19 and 20 is similar to the form shown in Figures 13 to 15 except that the blades 69 and 69 have been bent outwardly in angular relation to each other along the vertical line formed by one edge of the cutouts to provide an arrow head having three cutting edges it. The point H is, therefore, formed by the termination of three cutting edges instead of two. The bands 12 have flanges l3 thereon, while the tongues 14, cutouts I5 and lips 76 are only formed where the two blades contact. The bands '12 are bent in opposite direction to the bands 72, and the pin I5 retains the finished head on the shaft 42.

The preferred form of my invention is shown in Figures 21 and 22. The two blanks shown in Figures 1 and 2, and designated here as blades 14 and 14' respectively are bent outwardly in angular relation to each other along the vertical line of the edges of the cutouts to provide four cutting edges 15. The point 15 is, therefore, formed by the termination of four cutting edges. Near the point 15, tongue 16 fits through cutout TI and meshes with lip 18 to hold the blades firmly together there. More tongues and cutouts and lips may be used to hold the blades together from the point up to the forward end of the socket if deemed necessary. The uppermost bands 81 are oppositely bent and the bands iii have flanges 88. Since this preferred form of the invention is composed of the preferred form of blades shown in Figures 1 and 2, its assembly and finishing has been earlier described in connection with the description given of Figures 1 to 9, inclusive. Along the line of contact of 'form two additional cutting edges 9%).

the two blades from the point to the forward end of the socket the blades are welded securely together. When finished, the arrow head may be secured in place on an arrow shaft 42 by a pin 82 driven through a small hole in one of the uppermost bands 8|.

Figures 23 and 25, inclusive, show how the two blanks of Figures 1 and 2 are used to make a modified form of the invention. The blades 83 and 33 have bands 8 3 with flanges 85, while bands 84 extend in the opposite direction to these bands. The tongues 86 are formed in rows on each side of the socket in parallel relation to the vertical center of the socket, while the tongue 31 is formed adjacent the point 38 of the blades. The blades are then bent in opposite directions at right angles to the blades to form wings 3Q; These wings lie in the same vertical planes at right angles to the blades and form four cutting edges 92, while the blades themselves Thus an arrow head having six cutting edges is provided.

The tongues all fit in cutouts 9i and tips 22 formed by the cutouts are pressed together to form a smooth exterior surface, as previously described. In addition the blades are Welded or soldered firmly together, the entire arrow head being finished just as in any of the other forms described.

In Figures 26 to 28, the blades 93 and 93 respectively are a variation of the form shown in Figures to 12, inclusive, and form a modified form of the arrow head shown in Figures 21 and 22. Here the bands 96 of the blades are without flanges formed by cutouts .95. The top bands Q5 are bent in the opposite direction to the band 94. One or more tongues 9? are used to hold the blades together from the point to the fore end of the socket, and are received in cutouts 93 with lips 39, all compressed together in the assembled head as previously described.

In this form, the blade 93 and the blade 93 have a portion Hit! and I06 respectively lying in the same plane, but extending in opposite directions from the socket containing the shalt 22. The other portions ii)! and liii' extend at right angles to the blades in opposite directions to each other. Thus four cutting edges IE2 are formed, and the point I93 is formed by the termination of the four cutting edges.

This form of arrow head may also be made of the blades shown in Figures 1 and 2, in which case it will have the addition of flanges to contact the arrow shaft 42.

In all instances, the blades are welded securely together from the very tip of the point up to the forward end or" the socket, and also may be welder or soldered together at any other place desired, to make a firmer, stronger, more rigid arrow head. As a finishing touch, the arrow head may be solder-dipped, or otherwise similarly treated, if desired, to give it a better appearance.

The two blades in contact along the edges make a very strong and rigid two-edged arrow head, suitable for hunting and for practice'shooting. But when the blades are bent outwardly in angular relation to each other as desired, more cutting edges are provided, which makes a very strong and rigidand superior arrow head for hunting that assures deeper penetration of the arrow into big, tough-skinned game animals, which in turn quickly causes the death of the animal, because more veins and arteries are severed, and the wound sags open, inducing greater internal hemorrhage as well as causing more spillage of blood externally, which latter makes the trailing of wounded game much easier.

Due to their manner of construction, these arrow heads are very strongl and rigidly made, and will not curl, bend or come apart upon striking a bone or other hard'substance.

There has thus been'provided an arrow head formed of two mating blades that can be bent in any desired angular relation to each other to form a plurality of cutting edges, and are provided with unique means for retaining the head on the arrow shaft. Means also is provided for retaining'the blades in close contact with each other.

The shaping of the two mating blades in angular relation to each other to form a B-edged, or a, 4-edged, or a G-edged arrow. head may be imparted during the process of stamping out the blades and the forming of the bands and cutouts, or it may be done after the blades are assembled together and securely tongue-latched and welded in place. Even the person purchasing the arrow head may, if he so desires, bend the blades to suit his own particular fancy.

It is believed that the foregoing description will clearly set forth the structure and advantages of 1 the invention to those skilled in the art. It is also to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided they fall within the spirit of the invention and the scope of the appended claims.
