It is common practice for archery enthusiasts to construct arrows from available separate components including arrowheads, arrow shafts, feathers, and nocks. Various conventional apparatus is known for mounting feathers to the shafts and further for mounting the nocks to the shaft. Mounting of the arrowhead to the arrow shaft, however has normally been accomplished by hand. This is usually done by utilizing a hard-setting glue to rigidly fix an arrowhead to the arrow shaft. When this is attempted manually, the outcome is not infrequent that the arrowhead is mounted to the shaft with the arrowhead centerline offset from the axis of the shaft. This misalignment causes inaccuracy in the flight of the arrow and further increases possibility of breakage of the arrow once it strikes a hard surface.

It may be understood from the above discussion that it is desirable for archery enthusiasts or for arrow manufacturers to obtain a device that would facilitate mounting of an arrowhead to an arrow shaft with the arrowhead centerline coaxial with the arrow shaft axis. The apparatus of the present invention accomplishes this by providing an arrowhead support and a shaft sup port both of which are mounted to a common base. The arrowhead support holds the arrowhead with its centerline lying along a prescribed axis and the shaft support holds the shaft with its longitudinal shaft axis coaxial with the prescribed axis. The arrow shaft support is movable along the base to enable the arrow shaft to be moved translationally along the prescribed axis into the shaft receiving opening of the arrowhead, thereby mounting the arrowhead to the arrow shaft with its centerline coaxial with the shaft axis.

SUMMARY OF THE INVENTION An arrowhead setting device is described herein comprising an elongated base having mounted thereon an arrowhead support means and a shaft support means. The arrowhead support means is utilized to receive and support an arrowhead with its shaft receiving end facing toward the shaft support means and with its longitudinal centerline coaxial with a prescribed axis. The shaft support means is utilized to receive and position an arrow shaft with its arrowhead receiving end pointed toward the shaft receiving opening and with its Shaft axis coaxial with the prescribed axis. The arrowhead support means and shaft support means are translationally movable toward and away from each other along the prescribed axis.

It is a first object of my invention to provide an arrowhead setting device that serves to quickly and efficiently mount an arrowhead to an arrow shaft with the longitudinal axis of the arrow shaft and the longitudinal centerline of the arrowhead coaxial with one another.

It is another object of my invention to provide such a device that is simple in construction and easy to use.

It is a further object of my invention to provide such a device that may be utilized with arrow shafts having varying diameters.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to FIG. 3 of the drawings, an arrowhead and a portion of an arrow shaft are illustrated as indicated by the

reference numerals

10 and 11 respectively. It may be noted that the arrowhead 10 is of the hunting variety having two opposed blades 10a convergng to a forward point 10b. A rearward end 12 of the arrowhead is open to receive a tapered forward end 13 of the shaft 11 for mounting purposes. It is the primary purpose of the present invention to facilitate mounting of the arrowhead 10 to the shaft 11 so that the centerline of the arrowhead 10 and the longitudinal axis of the shaft 11 lie coaxial with one another.

The arrowhead setting device as illustrated in FIGS. 1 and 2 basically includes an elongated base 16 having an arrowhead support 17 at a forward end thereof and an arrow shaft support 18 slidably mounted thereto. The arrowhead support 17 is utilized to support the arrowhead 10 with its rearward end 12 facing the shaft support 18 and centered along a prescribed axis X-X.

The shaft support 18 is also utilized to receive and support the arrow shaft 11 with its longitudinal axis coaxial with the prescribed axis XX. The shaft support 18 however is longitudinally movable along the base 16 to enable the shaft 11 to be moved translationally along the prescribed axis to facilitate insertion of the advancing shaft end 13 into the open rearward end 12 of the arrowhead.

The arrowhead support 17 is illustrated in greater detail in FIGS. 3, 4 and 5. Support 117 is comprised of vertically spaced mounting blocks 21 fixed to opposite sides of a guide plate 23. The arrowhead support is mounted to the forward end of the base 16 by means of an upright support 22 fixed between the support 17 and the forward end of the base 16. As shown in FIGS. 1 and 5, the arrowhead mounting blocks 21 each include a rearwardly facing recess 21a. Recesses 21a allow clearance for additional blades (not shown) which are commonly utilized with hunting arrow tips. The guide plate 23 also includes a recess 23a that includes forwardly converging guide surfaces 24 (FIG.

3). The surfaces 24 converge to a point on the prescribed axis X-X. The surfaces serve to guide the.

pointed end b of the arrowhead 10 to a point along axis X X as it is inserted within the arrowhead support 17.

Means for laterally adjusting the position of the arrowhead within the arrowhead support 17 is provided in the form of lateral adjusting screws 26. Adjusting screws 26 are utilized to laterally center the arrowhead 10 along the prescribed axis XX. The screws 27 may also be utilized to enable adjusting of the support 17 to accommodate arrowheads having varying breadth across the blades thereof.

Elevation of the arrowhead 10 relative to the base 16 is determined by the upright support 22 but may be accurately adjusted through means of vertical adjusting screws 27 and locking nuts 28. The adjusting screws 27 extend vertically through the blocks 21 and guide plate 23 to a pair of upright spacer blocks 29. The locking nuts 27 are provided on the screws 27 adjacent the upward facing surface of the mounting blocks 21 and are utilized to lock the screws 27 against undesired rotational movement within the arrowhead support 17.

The shaft support 18 may best be described with reference to FIGS. 1, 2, 3, and 6. The shaft support 18 is illustrated comprising a plurality of arrow shaft dies 31 removably mounted within a die support block 32. The die support block 32 in turn is fixed to a dovetail slide 37 that it carried within a complementary way 38 formed longitudinally along the base. The way 38 is oriented along the base 16 to enable translational movement of the shaft support 18 and thereby the arrow shaft 11 held therein along the prescribed axis XX.

The die support block 32 is comprised of two separate block sections 33 that are hinged together by a hinge 34 for pivotal movement relative to one another about an axis parallel to the prescribed axis XX. The block sections 33 each include a longitudinal groove 33a of which together from a rectangular channel for receiving the dies 31. As shown in FIG. 6, the dies 31 are each divided in half to form two die section 35. The sections 35 include longitudinal recesses 35a that, when the sections are brought together, form a circular aperture 36 centered exactly along the prescribed axis XX. The aperture 36 includes a diameter equal to the diameter of the shaft 1 I. It is intended that the dies 31 be removable from the die support block 32 to enable replacement with different dies having apertures of varying diameters to accommodate arrow shafts having similarly differing diameters.

In operation, the user first inserts an arrowhead 10 within the arrowhead support 17 so that the point 10b contacts the point of the converging guide surfaces 24, and the blades 10a engage the ends of the lateral adjusting set screws 26. It may be assumed that the set screws 26 have previously been adjusted to laterally center the arrowhead 10 along the prescribed axis XX and that the vertical adjusting screws 27 have also been adjusted to set the centerline of the arrowhead angularly along the axis. Once the arrowhead 10 has been inserted within the arrowhead support 17, the user may then mount a shaft 11 to the shaft support 18. He does this by first pivoting the upper block section 33 about the axis of hinge 34 to an open condition. The arrow shaft may then be fitted within the recesses 35a formed in the die sections 35 of the lower block section 33 as illustrated in in FIG. 3. When the shaft 11 is longitudinally positioned with the forward end 13 rearward of the die support blocks 32 the user may close the upper block section 33 over the shaft 11 so that the upper die sections 35 come into contact with the shaft 11. With the shaft so supported, the user then applies a hard-setting glue to the forward end 13 of the shaft, subsequently slides the shaft, along with the shaft support 18, toward the arrowhead support block 17 to thereby insert the forward end 13 into the open rearward end 12 of the arrowhead 10. The joined arrowhead 10 and shaft 11 may be removed from the device after a period of time sufficient to allow the glue to set. This is done simply by moving the shaft and shaft support rearwardly relative to the arrowhead support 17 and again opening the upper block section to allow access to the shaft. The resulting completed arrow is thereby formed with the head 10 mounted exactly along the longitudinal axis of the shaft 11.

It may become obvious from the above disclosure and accompanying drawings that various changes and modifications may be made therein without departing from the scope of this invention. It is therefore intended that only the following claims be taken as definitions of the present invention.
