6 Claims. (Ci. 273-l0e.5)

This invention relates to spear and arrow missile constructions which include av pivotally mounted barb. More particularly it relates to an improved arrow tip construction wherein the barb is readily xed in either a forward or backward direction as desired by an archer.

Although this invention may be used in many applications its advantages are particularly evident when used in the sport of bow fishing in which, instead of using a rod and reel, the archer-fisherman shoots his fish with a bow and arrow, testing his skill against the darting movements of a fish, against the difficulties imposed by varying contours of a stream bed or lake bottom and against deceptive refractions of light rays as they pass through the surface of calm or active water. Usually the types-of ish sought by such Sportsmen are rather small and active varieties, for such fish provide the most diicult targets and the greatest tests of skill. The iish may range in size, however, from a few ounches to about fifty pounds.

In this type of fishing the chances of injuring the arrowheads are great because the stream bed or lake bottom may be rocky, or snags may partially screen the swimming sh. These and similar hazards can cause serious damage to arrowheads which contain several moving parts or comparatively delicate movements. Moreover, when the fisherman fires at his target the barbs in the arrow must be ready to pierce or embed themselves in the flesh of the fish; a movable type of barb must be in proper working order not only when it is first used but also after it has been used several times. It must not be easily broken or susceptible to malfunctioning after use on only a few occasions.

The arrowhead must also be operated easily. Once a fish is hit and lifted from the water. the arrow must be withdrawn, but when the weather is cold, for example, skillful manipulation of an arrowhead is diiiicult, and the ordinary problems of handling a still' active fish covered with water and perhaps other slippery materials are still further enhanced. An archers enjoyment is considerably diminished when he lmust cope with clips or collars, or a number of separate parts in the arrowhead to release his arrow from the iish.

3,164,385 Patented Jan. 5 1965 forward section of the arrow tip. In another, an outwardly smooth, inwardly threaded collar must be forced over outstanding spring-biased vane portions of the barb to hold the vanes close to the rear of the tip member as it is being withdrawn from its target.

A third type of arrowhead construction includes a barb member which is pivotally arranged in an aperture in the forward portion of the tip. Such constructions provide for withdrawing the arrow from the target by allowing a pivotal reversal of the direction of the barb vanes after the arrowhead is thrust clear through the target. The arrow is then withdrawn by reversing the barb, that is, by reversing the direction which the vanes incline with respect to the arrowhead and shaft. One of the problems with this construction, however, is to provide a simple means to hold the barb member in target-engaging position initially and then to permit the barb to be reversed. The arrangements heretofore provided have all been difiicult to set and/or difficult to reposition when it is desired to withdraw the tip from its target.

In one such arrangment a retrieving line has been tied to a vane portion of the barb, the other end of the line being held by the archer and the weight of the line being relied upon to hold the barb in a rearwardly directed position relative to the arrow shaft. In a related arrangement the retrieving line is not fastened to the barb but is fastened first to the shaft and then looped or tied around the vane of the barb before the arrow is discharged. A third arrangement includes a slot or groove on the outer surface of the arrow tip, the barb being formed from a resilient material sothat the vane portion may be snapped into the slot and freed by springing or prying it out of such slot. Still another arrangement includes a barb having a portion which is wedged into the aperture; and the barb is reversed or eliminated either by forcefully twisting it against the friction provided by the wall of the aperture, or by pulling the barb out of the arrowhead entirely.

It is therefore one object of this invention to provide an improved arrow tip having yan adjustable barb which may be readily directed forwardly or rearwardly along the 'arrow as desired by the archer.

It is `another object of this invention to provide an improved arrow tip having a pivotally disposed barb readily maintainable in fixed relationship to the remainder 1 of the ,arrow tip by a barb locking member',

Heretofore several different types Vof arrowheads have been used. In one type a pair of blade-like barbs are fastened loosely together upon a' pivotal mounting within an arrow tip so that theywill fold backward into a slot in the tip. The tip is slidably disposed Aover the forward end of an arrow shaft, the rearward portion of the tip forming a sleeve in which the shaft is slidably engaged. Both blades are free to pivot outwardly from their mounting when the forward end of the shaft is forced far into the sleeve between the trailing edges of the blades. blades fly out when the shaft is forced quickly forward as the arrow is discharged or as it strikes itstarget. One particular drawback of this type of vconstruction is that the pivotal mounting of the blades is easily damaged by forceful shocks received from the shaft, a drawback which impairs the functioning of the entire arrangement after even use on only a few occasions.V Also the blades are easily bent so that they may not be readily pivoted or pressed back into the arrow tip.

In another type of arrowhead the barb member must either be removed from the assembly or compressed within it by using a slidable collar. Such constructions require types of engagements which are difficult to manipulate. In one, the removal of the barb requires a complete disengagement of an outwardly smooth and hard-to-grasp It is another object of this linvention to provide an improved arrow tip having means disposed in an indirect shock receiving position for fixing a locking member against adireotionally Iadjustable barb member.

it is still another object of this invention to provide an improved .arrow tip in which all components are easily accessible and readily manipulated under adverse conditions such as cold temperatures and slippery environ- The mental circumstances found in bow fishing.

Other objects and 'advantages Vwill'be seen from an examination of the following detailed description and the accompanying drawings. y

In one embodiment of this invention the arrow tip comprises a point member and a barb member. The barb member includes a first portion disposed in a pivotal engagement with the point member and a vane por-tion movable about said pivotal engagement, the vane portion being always positioned in an .outwardly substantially oblique direction relative to the point member. A locking member is movably disposed on the point member. Means are disposed'on the point mem-ber for lixing and maintaining the locking member upon the barb member first portion to secure the first portion and the vane portion in a fixed position relative to the point member.

For a more complete understanding of this invention annesse reference should be made to the accompanying drawings in which:

FlGURE'l is a perspective View of an arrow tip and shalt assembly;

FIG. 2 is ya sectional view along line 2-2 of the arrow tip st own in FlG. l, the parts of the arrow tip being dis posed kin a iirst position;

FlG.' 3 is a sectional view of the arrow tip shown in FlG. l, lalso along line 2 2, but showing the paris in full lines in a second position;

FIGA is a cross-sectional view talten along line '--fl of FG. 2; and

FlG; is an elevational view ot the barb shown in FIGS. l, 2, 3 and 4.

Referring now to the drawings, which illustrate one embodiment of this invention, and more particularly to FlG. l, an arrow 4shaft lll is provided with a point member l2 mounted upon la locking Vmember ld at one end of the shaft. A barb l@ is disposed through the lpoint mein ber in front of the locking member, and to the rear of the barb a cord l for retrieving the arrow is attacbed to the locking member. A slot lor any other re or apparent means may be provided if desired for fac ing the attachment of cord lil.

ln the pointV member l2, which is ordinarily formed oi ya hardened metal to resist yinjury and maintain a sharp point, a'transverse aperture 22 is positioned to intercept a longitudinal axis, illustrated by line 2d, drawn tbrough the point member. The barb member entends through aperture 2. Vso .that a tirst portion 26 .of me barb member is kpositioned generally within the aperture and vane portions' are positioned generally outside of tbe aperture, the vane portions also extending oblique-ly from the point member'and itslongitndinal axis. The transverse aperture has a large enough diameter so :that the first portion of the barb member may be rotated freely. However,

y the oblique position of the vanes precludes any substantial transverse movement of .the rst Iportion 26 of the barb member with respect to the longitudinal axis, thus preventing accidental separation oi the barb member le from Vthe point member l2.

Inithe embodiment of this invention which is illustrated in the drawings a second 'aperture d@ is formed in the trailing section lla of the point member which extends rearwardly .from transverse aperture 22. The section is drilled and tapped along thelongitudinal axis 24 from the rear of the point member clear through to transverse aperture 2?. in order to locate the second aperture in a direction intercep'ting the transverse aperture. This second apertureti, easily seen in FlG. 3, is provided'with internally disposed `threads 32 adapted-to engage and to direct ythe course of an externally threaded portion 3d of the locking mem-ber positioned in the second aperture.

Y Communication or" the second aperture with the tiret ape ture 22 `is unobstructed inorder that the locking member `portion 34 may be inserted `from the rear of the point member through the second aperture and kdirected into the first aperture.' i' f The front end of vthe locking member includes an anvil l 36 for engaging a cooperatively arranged first lengagement surface 38 on the first portion of the barb member, theyanvil being provided with a second engagement surface 46 generally conformed to the contour of the first engagement sur-face of -tbebarb member. Vln the illustrated embodimentboth of these snriacesare subsan tiallyfflat so that, when fitted against each other, even a high degree of rotational force applied to the vane ypor- Y tions ofk the lbarb Will not effect a separation of the snr-v aces. However,V these `surfaces are not limited in shape tothe dat facesillustratedg in fact, they may be concave or convex, or even include complementary types of keyed or -frictional 'annangements so long as the engage- Vnient:between them is resistant to rotational Aforce Which may be applied to thebarb member.

Also, in the illustrated embodiment, the rst portion of 4j? the barb is formed with an engagement that side of the portion which is o 33, since it is by stamping The adf'antag face is provided b against which th A ber, esrecially Whe are e barb lirst po dened and te of tbe barb the fr st portion En apart 7from rn of e forward sine at a l times. eren when the 'Flrst and second engagement surfaces are disposed aga t each other in 'lira locltig en nt, il a locking arrangement requiring more space than comi pl-:mentary dat surfaces is desired.

The rst portion oi the barb being loosely c in aperture 4.a and the rede por posed in outwardly oblique dir "fo vane portions lie in cir' c which are spaced apart from the transverse aperture, Outer may be moved along such paths to any point in those paths by applying a rotational crce or ranking rnc-Lion to tbe barb. Jiien the desired point in paths L5/. is reached the vane end portions may be halted and sec ed by ailxing the second engagement surface of the locking member upon the first portion of the barb member. Usually, of coarse, when t tre barb member is secured in a fixed position relative to tbe point member, the vane portions extend obl o ly in either tbe forwardmost or rearward-.most directions along the arrow tip.

When it is desired to secure the barb varies in a direction toward the rear the barb is lirst turned to its desired position, the trst engagement surface Ed thereby being positioned to face the second engagement surface d@ of the locking member. The locking member is then rotated in the direction indicated by arrow do in 2, the effect of such rotation being to move anvil 36 through the second aperture Sti and tighten the second engagement surface of the locking member against the first engagement surface of the barb member. As illustrated, the tightening of the locking member not only results in a firm engagement of the rst and second engagement surfaces but also drives the anvil against the first portion of the barb member to press the rst portion against the forward side d?. of transverse aperture 22, thus disposing the first portion of the barb between two rictional engage ments. ln such disposition of the locking member, point member and barb member, the position of the barb is fixed with respect to bot-h of the other members.

Correspondingly, when it is desired to change the direction in which the barb member is disposed, for example, from a rearward direction to a forward direction as illustrated in FlGS. 2 and 3, the locking member is rotated in the direction of arrow ed. The interaction of the external threads 34 on the locking mem-ber and the internal threads 3,2 of the point member directs the locking member away from theV barb member iirst portion, thus disengaging second engagement surface d@ from the iirst engagement surface 3d on the first portion of the barb. Without the rictional engagement provided by the locking member and the opposition oi the `tall side 4Z of the transverse aperture, the looseness of the barb in the transverse aperture permits the barb to be rotated to any desirable position.

At this point, if should be desired to the barb in a newly chosen position, the locking member be ro rated in the direction oi arrow de to reposition the second engagement surface against the barb member lirst portion. The barb member iirst portion is formed, in its preferred embodiment, to present at least one exceptional engage ment surface 38 to the second engagement surface 40 of the locking member. Thus, the first engagement surface 38 is a fiat face which is complementary to the fiat face of the second engagement surface 40. However, when the barb is rotated to the point where surface 38 faces the front side 42 of the transverse aperture, it may be desirable to have the area of the barb first portion which is opposite surface 33 formed, as is surface 38a, to cooperate with the second engagement surface 40 on the locking member. Instead of grinding surface 38 flat, then, it has been found advantageous to press the barb first portion and to obtain two exceptional engagement surfaces, 33 and 38a.

Threads 32 are the means illustrated by the preferred embodiment of this invention for fixing the second engagement surface of the locking member upon the barb member first portion 26. Other possible forms of such means are cooperating lugs or slidable frictional engagements which fix -the locking member in position, and it is intended that the invention not be limited to the particular form of means shown in the preferred embodiment,

Threads 34 which cooperate with threads 32 may be formed on any suitable member receivable by the point member 12. An adapter 50 may be provided and an arrangement therein for aflixing it to shaft of the arrow, such an arrangement being provided in the preferred embodiment by a drilled sleeve portion 52 of the adapter. Such an adapter is not necessary, however, as long as the forward end of shaft 10 is provided with a locking member arranged to cooperate with threads 32.

A particular advantage of such an arrangement is that, in order to loosen or tighten the locking member readily, all that the operator need do is hold the point member and barb member between the thumb and first finger of his left hand and twist the shaft of the arrow with his right hand. Thus, the second engagement surface 4i) may be engaged upon or disengaged from the barb member first portion with a minimum of effort, even under the most adverse weather and environmental conditions.

Another advantage of this invention is the disposition of the threads 32 in a protected location with respect to the reception of shock by the rest of the parts. When the barb member is positioned in the rearwardmost position, as shown in FIG. 2, the anvil 4t) is directly in contact with the barb member first portion, which, in turn, is directly in contact with the front side of wall 42 in the transverse aperture 22. If the arrow happens to strike a rock or a snag, the shock travels along the point member into the locking member, which is disposed principally against the first engagement surface 38, and rearwardly therefrom back to the arrow shaft it). Any shock traveling from the point member in the direction of threads 32 threads 32 are not subjected to sudden or direct stresses.

It will be immediately apparent that various modifications may be made without departing from the principles indicated herein, but such modifications as fall within the true spirit and scope of the invention are to be understood as being included in the Vappended claims.
