Hunting arrowhead with bleeder ring

Hunting arrow utilizes an arrowhead having a ferrule and a plurality of blades, and a cutting ring is secured to the blades. The blades are secured to the ferrule by a tip and by a retainer nut adjacent to the shaft. Different configurations of rings may be utilized, and the rings may be secured to the outer or inner portions of the blades. Different configurations of both arrowheads and rings which may be secured to an arrow shaft are illustrated and discussed.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1is a perspective view of a hunting arrowhead or broadhead10of the present invention.FIG. 2is an exploded view of the arrowhead10of FIG.1. For the following discussion, reference will be made toFIGS. 1 and 2. The arrowhead10is shown inFIG. 1with a a pair of blades40and a cutting ring80secured to the blades40. The arrowhead10is secured to an arrow shaft2and is appropriately aligned with the longitudinal axis of the shaft2, as is well known and understood for arrowheads.

InFIG. 2, only a single blade40is illustrated. The shaft2includes a front end face4, and a threaded bore6extends into the shaft2at the front end face4. The arrowhead10includes a ferrule or shank12, and the ferrule or shank12includes a lower threaded portion14which extends into the threaded bore6of the shaft2to secure the arrowhead10to the shaft2.

The ferrule12also includes a blade locking threaded portion16located a slight distance forwardly or upwardly from the lower threaded portion14. A retainer nut70, which will be discussed below, has internal threads which engage the threaded portion16.

A plurality of slots extend into the ferrule12for receiving the blades40. Two slots18are illustrated in FIG.2. The slots18are shown in dotted line.

The ferrule12has a front end20, and a pin22extends forwardly from the front end20. A tip30, shown in partial section, includes a bore32which receives the pin22. It will be understood that the tip30could include a pin, and the shank12could include a bore for receiving the pin, if desired. The pin and bore may be press fitted or threaded, as desired.

The bore32extends upwardly from a tapered recess34. When the blades40are disposed in their respective slots18, the upper portions of the blades extend into the recess34to provide an upper lock for securing the blades to the ferrule12.

The blade40has a generally triangular configuration, with a flat side42extending into a slot18. The blade40also has a sloping side46. A cutting edge48is defined at the outer portion of the sloping side46. The sloping side46extends rearwardly to a bottom or base side50. The bottom or base side50includes a slant portion52.

There are two open areas shown for the blade40, an upper open area54and a lower open area58. The open areas54and58are shown divided by a strut56. Extending “outwardly” into the side46from the lower open area58is a recess or notch60.

Generally aligned with the recess60is a slit44. The slit44extends through the flat side42. The purpose of the slit44is to allow a ring80to be inserted into the open area58. The ring80is then placed in the recess60, as shown in FIG.1. The slit44is shown inFIG. 2exaggerated for illustrative purposes. The slit44is preferably sheared to minimize its width. The slit44is essentially closed when the retainer nut70is secured to the ferrule12and when the tip30is secured to the ferrule12. The combined forces against the blades exerted by the tip30and by the retainer nut70essentially close the slit44.

The notch60includes three sides, including a top or forward side, bottom side, and an inner side, with the top and bottom sides generally perpendicular to the longitudinal axis of the arrow shaft2. The inner side of the notch60is generally parallel to the longitudinal axis of the shaft2. The orientation of the sides of the notch60provide the appropriate orientation for the ring80with respect to the shaft2and the blade(s)40.

The configuration of the notch60insures that the ring80is locked to the blades and will remain with the arrowhead when the arrow is withdrawn from the game.

The retainer nut70includes an inner threaded portion72which matingly or threadedly engages the threaded portion16of the ferrule or shank12. The nut70also includes a sloping portion74which extends upwardly and outwardly from the threaded portion72. The angle of the sloping or tapered portion74matches the slope of the tapered or slant portion52of the blade40. Accordingly, when the blade40is inserted into a slot18, the nut70is secured to the ferrule12, and the sloping or tapered portion74is disposed against the tapered or slant portion52of the blade40to secure the blade40to the ferrule12. In actuality, all of the blades40will be disposed in their respective slots18before the nut70is secured to the ferrule12.

At the top of the arrowhead10, the tip30is also secured to the ferrule or shank12to retain the upper portion of the blades40to the ferrule or shank12, as discussed above. The taper of the recess34matches the angular relationship between the inner side42and the sloping outer side46to help securely hold the blades to the ferrule12.

InFIG. 3, a ring80is shown in a slightly perspective view.FIGS. 4 and 4Ashow in partial section two embodiments of the ring80. InFIG. 4, the ring80is shown to include a cutting edge82with a single beveled portion84. InFIG. 4A, a pair of beveled portions84and86extending rearwardly and outwardly from the cutting edge82. It will be understood that whether a single beveled edge or a double beveled edge is used for a ring is essentially immaterial for purposes of the present invention.

For inserting the cutting ring80, the blades, typically 3 or 4, are stacked or aligned on top of each other, with the slits44also aligned. The ring80is then turned sideways and moved through the aligned slots44and into the lower open area58. The ring80is then rotated ninety degrees to the orientation shown in FIG.1and the ring80is disposed in the recesses60of each blade. With the blades40disposed apart, the blades are then ready to be secured to the ferrule or shank12.

The blades40are appropriately spaced apart and the inner sides42are then inserted into their respective slots18in the ferrule or shank12. The tip30is secured to the ferrule12and the retainer nut70is also secured to the ferrule to secure the blades in place. The arrowhead10is then secured to the shaft2.

FIG. 5is a side view of another broadhead type hunting arrowhead100which is an alternate embodiment of the arrowhead apparatus10ofFIGS. 1 and 2. The arrowhead100utilizes the same ferrule or shank12, with the lower threaded portion12which extends into the threaded bore6of the shaft2, as shown inFIGS. 1 and 2. The retainer nut70with the tip30, are used to hold a plurality of blades110to the ferrule or shank12.

The blades110differ from the blades40in the ring retainer design, and in the ring design itself. Two different ring designs or configurations are illustrated inFIGS. 5,5A and5B.FIG. 5Ais a slight perspective view of the ring80, andFIG. 5Bis a side view of an asymmetrical ring130. For the following discussion, reference will be made to FIG.5and toFIGS. 5A and 5B, as appropriate.

The blades110includes an inner, straight side112with a slit, not shown, but may be understood fromFIG. 2, a slant side116which includes a sharp edge118. Extending inwardly from the sharp edge118is an outer or exterior recess120.

The recess120includes a front or top or upper side, a bottom side, and an inner side. The upper or top side and the bottom side are generally parallel to each other and generally perpendicular to the inner side. The inner side is generally parallel to the longitudinal axis of the ferrule12and accordingly to the longitudinal axis of the arrow shaft2. (SeeFIGS. 1 and 2.)

The blades110also include and a bottom side124with a slant or tapered portion which extends into the retainer nut70, as discussed above. The bottom side extends from the slant side to the straight side to define with the straight side and the slant side a generally triangular configuration. The three sides also define within in them an open area126.

At the juncture of the slant side and the bottom side of the blade110in the open area126is an interior recess122. The recess122is essentially a mirror image of the recess120. The recess122includes three sides, a top side, a bottom side, and an inner side. A cutting ring extends into the recess122and is disposed against the inner side and the top side to lock the cutting ring to the arrowhead100.

The slit on the straight side of the blade110allows a cutting ring to be inserted into the open area126, as discussed above and below. The slant or tapered portion of the bottom side124extends into the retainer nut70, and the tip30receives the top portion of the blades to help secure the blades to the ferrule12. The ferrule or shank12includes slots18to receive the inner, straight, sides112of the blades, as also may be understood from FIG.2.

The recess120extends inwardly from the sharp, cutting edge118and into the outer portion or side116, as discussed above, for receiving an outer cutting ring, such as the symmetrical cutting ring80, illustrated in FIG.5A.

The outer side or portion116also includes the inner recess122for receiving a cutting ring, as also discussed above. The cutting ring may either be a symmetrical cutting ring, such as the ring80. An asymmetrical cutting ring130may also be disposed in the outer recess120or in the inner recess122, as desired. In other words, both types of cutting rings may be disposed in either the outer, exterior, or the inner, interior, recesses, as desired. While two types of recesses, outer and inner, are illustrated inFIG. 5, typically a blade will have either one recess or the other, and may have both.

The cutting ring80as illustrated inFIG. 5Ais repeated fromFIG. 3for comparative convenience with respect to the asymmetrical cutting ring130of FIG.5B.

For receiving an inner cutting ring, such as the asymmetrical cutting ring130, the inner or straight sides112of the blades110include slits, as discussed above, and as may also be understood from FIG.2. The ring130may be inserted into the open area124in substantially the same way the ring80was inserted into the blades40as discussed above. The asymmetry of the ring130is immaterial with respect to insertion the blades of an arrowhead. The ring130is illustrated as having three lobes or scallops132,134, and136. The lobes132,134, and136may be located equidistance apart, allowing aligned portions of the rings to be disposed in the aligned inner recesses122.

The locations of the lobes or scallops may, of course, be correlated with the separation of the blades on a particular shank or ferrule, and also in accordance with the number of blades desired for an arrow. Obviously, an inner recess may be located as desired in a particular set of blades for a particular arrowhead to accommodate the location of blades and the design of a cutting ring. Similarly, notches in the blades may be disposed in an offset relationship for receiving an asymmetrical cutting ring.

Another type of asymmetric cutting ring is illustrated inFIGS. 6 and 6A.FIG. 6is a side view of another alternate embodiment arrowhead150.FIG. 6Ais a side view of a cutting ring160for a blade110of the arrowhead150. For the following discussion, reference will primarily be made toFIGS. 6 and 6A. The ferrule12, the tip30, and the retainer nut70function substantially as they do for the blades110of the arrowhead100, and as they do for the blades40of the arrowhead10. The difference with the arrowhead150is the design of the cutting ring160. Also, the inner recesses122of the blade110are vacant. The cutting ring160is disposed in the outer recesses120of the blade110.

The cutting ring160includes a base162with a scalloped top cutting portion164. The base162includes a generally “flat” bottom166. Three slots170,172, and174are appropriately spaced apart in accordance with the spacing of blades110about the ferrule or shank12. The slots170,172, and174extend upwardly from the bottom166and terminate slightly below the cutting edge164. The slots170,172, and174are aligned with three lobes, providing an asymmetrical cutting edge164, but providing a generally flat bottom profile for the cutting ring. The slots170,172, and174extend into the recesses120and downwardly along the outer sloping sides116of the blades110. That is, the slots170,172, and174receive a portion of the outer side116. The distance between the top of the slots and the top edge164is appropriately dimensioned to extend into the recess120.

Note that the generally rectangular configuration of the outer recesses120of the blade110and the orientation of the blades with respect to the recesses assures that the rings, either a symmetrical ring80, or an asymmetrical ring, such as the ring130or the ring160, will not remain embedded in the game as the arrow shaft2and an arrowhead is pulled outwardly to remove the arrow from the game. Regardless of what type of cutting ring is used with a particular blade design or arrowhead design, the configuration of the recesses which receive them insures that the cutting rings will be locked to their blades.

FIG. 7is a side view of another alternate embodiment180of the arrowhead apparatus of the present invention.FIG. 7Ais a plan view of a blade190.FIG. 7Bis a side view of a cutting ring220. For the following discussion, reference will primarily be made toFIGS. 7,7A, and7B.

The arrowhead apparatus180differs from the arrowhead apparatus150primarily in the design of a cutting ring220. The arrowhead apparatus180includes the basic ferrule12, with its various elements as discussed above functioning in substantially the same manner as discussed above with the arrowhead apparatus10,100, and150. The arrowhead apparatus180includes a plurality of blades190. The blades190are substantially the same as the blades110. However, the cutting ring220is an inside cutting ring, extending into an inner recess208in each of the blades190, while the cutting ring160of FIG.6andFIG. 6Ais an outside cutting ring, disposed in the outer recesses120.

The blades190include an inner straight side portion192which extends into a recess18in the ferrule12, a lower side194which includes a tapered or sloping portion196which cooperates with the retainer nut70substantially as discussed above. The blades190also include an sloping outer cutting side198. The upper juncture of the cutting side198and the inner side192extend into the recess in the bottom of the tip30, substantially as discussed above.

The blades190also include an outer recess200and an inner recess208. The ring220is shown disposed in the inner recesses208of the blades190in FIG.7. The outer recess200is vacant.

Details of the outer or exterior recess200and of the inner or interior recess208are shown in FIG.7A. The outer recess200includes a top side202, an inner side204, and a bottom side206. The sides202and206are generally parallel to each other and generally perpendicular to the longitudinal axis of the shaft2and, of course, to the longitudinal axis of the ferrule12. The inner side204is generally parallel to the longitudinal axes of the shaft2and the ferrule12and generally perpendicular to the sides202and206. See FIG.2. Thus, with an appropriate ring, either a ring80or a ring130or a ring160, disposed in the recess200, the top side202bears against the ring as the arrow is pulled from the game and insures that the ring moves with the arrow and does not stay in the game as the arrow is withdrawn. The configuration of the recess200is substantially the same as that of the other outer ring receiving recesses discussed above.

The inner recess208includes a top side210, an outer side212, and a bottom side214. The top and bottom sides210and214are generally parallel to each other and are generally perpendicular to the longitudinal axes of the arrow shaft2and the ferrule12. The outer side212is generally parallel to the longitudinal axes and generally perpendicular to the sides210and214.

An open area216is disposed between the sides192,198, and194, substantially the same as with the blades110ofFIGS. 5 and 6. The blades110and190are substantially identical. However, it will be repeated that both outer recesses and inner recesses are illustrated for the blades110and190. While blades may include both inner and outer recesses, and inner and outer cutting blades, typically a blade will have either an outer recess or an inner recess for receiving a single cutting ring. For convenience, both outer and inner ring receiving recesses are illustrated.

The cutting ring220has the same general configuration as the cutting ring160. The cutting ring220includes a base222, a scalloped top cutting edge224, and a flat bottom. However, the ring220includes three slots230,232, and234which extend downwardly from the top cutting edge224, which is just the opposite from the slots of the ring160. The ring220is an inner cutting ring which extends into the recesses208, with the slots receiving a portion of the outer sides198to lock the ring to the blades. The portion of a ring220below a slot extends into a recess208and is appropriately dimensioned for disposition against the side212.

FIGS. 8 and 9are front views of arrowheads240and260, respectively, illustrating cutting rings of the present invention with a three bladed arrowhead and a four bladed arrowhead.

InFIG. 8, the arrowhead240includes a ferrule242and three blades244,246, and248are secured to the ferrule242. A cutting ring250is secured to the blades244,246, and248. Helping to secure the blades244,246, and248to the ferrule242at the front of the arrowhead240is a tip252. The tip252accomplishes its securing function substantially as discussed above.

InFIG. 9, a four bladed arrowhead260is illustrated. The arrowhead260includes a ferule262to which four blades264,266,268, and270are secured. A cutting ring280is in turn secured to the four blades264. . .270. A tip272helps to secure the blades264. . .270to the ferrule262, substantially as discussed above.

FIG. 10is a side view of an integral or monolithic arrowhead290. The arrowhead290includes a ferrule292with a lower threaded portion294which mates with an internally threaded bore at the front of an arrow shaft, as best shown in FIG.2. The ferrule292also includes a cylindrical central portion296.

Integral with the ferrule292are several blades, of which blades300and310are shown. Typically, the arrowhead290may have three blades spaced apart equidistant from each other. For convenience, only two blades300and310are illustrated in FIG.10.

The blade300includes an outwardly and downwardly sloping or slant portion, the outer edge of which includes a sharp cutting edge302, and a generally inwardly extending lower portion304. The blade310includes a similar outwardly and downwardly extending sloping or slant portion, the outer edge of which includes a sharp cutting edge312, and an inwardly extending lower portion314. The lower portions304and314extend from the ferrule292generally inwardly from the lower portions of the respective slant portions to the ferrule292.

Open areas324and326extend between the central portion296of the ferrule292and the slant portions and the bottom portions of the blades300and310, respectively.

A pointed, sharp tip320is defined at the juncture of the blades.

A cutting ring320, illustrated as a scalloped or asymmetrical ring, is integral with the blades. The ring320may also be symmetrical, as the ring80. The ring320includes a sharp cutting edge322. The integral or monolithic nature of the arrowhead290insures that the cutting ring320remains locked to the blades.

The arrowhead300may be molded or cast to provide the integral or monolithic unit. However, the edges of the blades and the cutting ring must be appropriately sharpened to define their respective sharp, cutting edges. Note how the cutting edge322of the cutting ring320blends directly to the cutting edges of the blades300and310, and of course of another or other blades, as appropriate.

FIG. 11is a front view of a three bladed arrowhead330. The arrowhead330includes a ferrule332and three blades334,336, and338. A cutting ring342is secured to the three blades334. . .338. The arrowhead330also includes a tip340.

FIG. 12is a front view of a four bladed arrowhead350. The arrowhead350includes a ferrule352and four blades354,356,358and360. The blades354. . .360are appropriately secured to the ferrule. A tip362is appropriately secured to the blades354. . .360and to the ferrule352. A cutting ring364is also appropriately secured to the blades354. . .360.

The cutting rings342and364are illustrated as being circular. They may be either symmetrical or asymmetrical, as desired.

FIG. 13is a front view of an arrowhead370. The arrowhead370includes a ferrule372and four blades374,376,378, and380. The blades374. . .380are appropriately secured to the ferrule372. A tip382is disposed at the front of the ferrule372and the four blades374. . .380.

A generally square cutting ring is secured to the four blades374. . .380. The cutting ring includes four portions, each of which extends between adjacent blades. The portions include a portion384between the blades378and380, a portion386between the blades380and374, a portion388between the blades374and376, and a portion390between the blades376and378.

FIG. 14is a front view of another arrowhead400. The arrowhead400includes a ferrule402and three blades404,406, and408are secured to the ferrule402. A tip410is disposed at the juncture of the three blades and the ferrule402.

A generally triangularly shaped cutting ring having three portions extends between the blades. A ring portion412extends between the blades406and408. A ring portion414extends between the blades408and404. A ring portion416extends between the blades404and406. The ring portions are illustrated as being generally straight, as are the cutting ring portions384. . .390of the arrowhead370.

The arrowheads ofFIGS. 11,12,13, and14may be made monolithic or integral, as by casting or molding methods, as with the arrowhead290of FIG.10. The arrowheads may alternatively be made of separate parts, as with the arrowheads10,100,150, and180ofFIGS. 1 and 2, andFIGS. 5,6, and7, respectively. With the present casting or molding technologies, the sharp edges of the blades and the cutting rings typically may require sharpening after the casting or molding processes.

FIG. 15is a schematic front view, very slightly tilted, or very slightly perspective, of another alternate embodiment420of the present invention.FIG. 15Ais a schematic front view, slightly tilted, or very slightly perspective, of the apparatus420of FIG.15.FIG. 15Ais tilted forwardly slightly more than FIG.15. For the following discussion, reference will primarily be directed toFIGS. 15 and 15A.

The arrowhead apparatus420includes a ferrule422, with a threaded lower portion424and a pointed tip426. A plurality of blades430are appropriately secured to the ferrule422. Three blades430are illustrated.

The blades430differ from those illustrated in the above discussed embodiments in that the each blade430includes a cutting edge432which is generally perpendicular to the longitudinal axis of the ferrule422and accordingly also to the longitudinal axis of an arrow shaft to which the ferrule422will be attached.

Each blade also includes a trailing edge434which tapers or slants rearwardly and inwardly from an outer tip436of each blade. Thus, the blades430are generally triangular in shape or configuration, as are the blades of the above discussed embodiments, but the orientation of the blades430on a ferrule is different from the blades of the above discussed embodiments. The blades430also have a different overall configuration or proportion from the blades of the above discussed embodiments.

A cutting ring450is appropriately secured to the blades430. The ring450extends into slits in the blades adjacent to, but inwardly from, the outer tips436of each blade430. The cutting ring450includes a sharp cutting edge452at the top or front of the ring. The ring450leads the blades in the arrowhead apparatus420, with the cutting edges432of each blade slightly below the cutting edge452of the ring450.

FIG. 16is a schematic front view, very slightly tilted, or a very slight perspective view, of an alternate embodiment arrowhead470of the present invention, comprising specifically an alternate embodiment of the arrowhead apparatus420ofFIGS. 15 and 15A.FIG. 16Ais a slightly tilted perspective view of the arrowhead apparatus470of FIG.16.FIG. 16A, likeFIG. 15A, is tilted forwardly slightly more than FIG.16. For the following discussion, reference will primarily be made toFIGS. 16 and 16A.

The arrowhead apparatus470includes a ferrule472, and the ferrule472includes a lower threaded portion474and a pointed tip476, similar to the arrowhead apparatus420. The arrowhead apparatus470also includes three blades480. The blades480are appropriately secured to the ferrule472.

The blades480include outer ends482, top sharp surfaces484, and bottom surfaces486. The blades480are generally triangular in configuration, like the blades430ofFIGS. 15 and 15A. The top, sharp, surfaces484are generally perpendicular to the longitudinal axis of the ferrule472, and accordingly of the arrow shaft to which the ferrule472is secured. The bottom edges486extend inwardly and downwardly from the outer edges482to the ferrule472.

A cutting ring490is secured to the outer ends482of the blades480. The cutting ring490includes a bottom surface492and a sharp top surface484. The sharp top surface494is planarly aligned with the sharp top surfaces484of the blades480.

The length of the outer ends482of the blades480is the same as the height of the ring490. This is best shown in FIG.16A.

Both the arrowheads420and470may best be made as integral or monolithic elements, as discussed above. Casting or molding processes of current technology may be best applied to making such monolithic or integral arrowheads. Again, the cutting rings are locked to their blades.

It will be noted that only the blades40ofFIGS. 1 and 2are illustrated as including a strut56for dividing the open area within the blades into two open areas54and58. The other blades illustrated may also include such struts for providing strength for the blades. The blades of broadhead arrowheads may include open areas for reducing weight, and the struts provide structural reinforcement for the blades. For convenience in illustrating the elements of the present invention, struts are only shown inFIGS. 1 and 2.

Moreover, while the cutting edges are shown as generally smooth, it will be understood that they may alternatively be serrated, etc.

Blades of broadhead hunting arrows are typically razor thin and razor sharp. The thickness of the blades and rings illustrated in some of the drawing Figures have been exaggerated as required for illustrative purposes. In some drawing Figures, the blades are schematically illustrated merely as single lines without inherent thickness.

Either exterior notches, on the sharp side of blades, or interior notches, on the inside of a sloping portion of a blade, extending into the sloping portion from an open area of the blades, or communicating therewith, or both types of notches, may be used with cutting rings. Both interior and exterior notches lock the cutting rings to the blades.

While the principles of the invention have been made clear in illustrative embodiments, without departing from those principles there may occur to those skilled in the art modifications of structure, arrangement, proportions, the elements, materials, and components used in the practice of the invention, and otherwise, which are particularly adapted to specific environments and operative requirements. The appended claims are intended to cover and embrace any and all such modifications within the limits only of the true spirit and scope of the invention.
