NOCK SETTERS Filed April 10, 1962 IN ENTOR Jb/ Iz 440/ era V M91 7. 1 nun x a III H I W M FM I 1 a 1| L E :z a 1 M f M 274 ATTORNEY United States Patent M 3,121,281) NQQK SE'ITERS John J. McFadden, 224 E. Durham St, Philadelphia, Pa. Filed Apr. 10, 1962, Ser. No. 186,548 1 Claim. (Cl. 29-20%) In order to obtain true and accurate flight of an arrow, the .nock must be in longitudinal alignment With the longitudinal axis and grain of the shaft.

The conventional manner of assembling the nook to the shaft is to apply glue to an end of the shaft, hold the shaft in one hand and the nook in the other hand, move the shaft into the nook and adjust the nook back and forth until, depending on the eye, it is beiieved that the nook and shaft are in proper alignment.

The object of this invention is to devise novel means for assembling the nook and shaft so that the nook will be in longitudinal alignment with the grain and longitudinal axis of the shaft.

With the foregoing and other objects in View as will hereinafter clearly appear, my invention comprehends novel means for supporting and positioning the nook, novel means for supporting and aligning the shaft, and novel means for clamping the shaft in position until the glue has set.

A further object is to devise novel means to clamp the nook in its aligned position.

A further object is to devise a novel support on which the nook and shaft can be mounted in accurate alignment with each other.

A further object is to devise a novel shaft supporting and aligning tube With a nook receiving cap movably con neoted with an end of the tube.

For the purpose of illustrating the invention, I have shown in the accompanying drawings preferred enbodiments of it which in practice will give satisfactory and reliable results. It is, however, to be understood that the various instrumentalitics of which the invention consists can be variously arranged and organized, and I do not therefore: desire to be limited except by the scope of the appended claim to the exact arrangement and organization of these instrumentalities as herein set forth.

FIGURE 1 is a top plan view, partly broken away, of a nook setter embodying my invention.

FIGURE 2 is a section on line 2 of FIGURE 1.

FIGURE 3 is a section on line 3 of FIGURE 1.

FIGURE 4 is a sectional detail showing more particularly the nook receiving means and a portion of the shaft of an arrow.

FIGURE 5 is a longitudinal sectional on line 5 of FIG- URE 1 showing a nook and shaft in longitudinal alignment and clamped in position.

FIGURE 6 is a sectional elevation of another embodiment of the invention showing the parts in open condition.

FIGURE 7 is a sectional elevation of the parts shown in FIGURE 6 but showing such parts in closed condition.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings:

Referring first to the embodiment of FIGURES l to 5, a support 1 of any desired material is provided in its top face with a plurality of longitudinally extending grooves 2 disposed side by side and preferably parallel to each other for the reception of the shafts 3 of the 3,121,280 Patented Feb. 18, 1964 arrows which are to be assembled with nooks 4. The support is provided at opposite sides of the grooves with holes 5 to receive aligning pins 6 for the shaft clamping blocks 7. The blocks 7 are guided by the aligning pins and are provided with actuating rods 8 in threaded engagement with a crossbar 9 on the support.

The support 1 has a crossbar 10 provided with nook receiving recesses 11 which are in longitudinal alignment with the grooves for the shafts.

A nook carrying bar 12 is rotatably mounted on the support and has at opposite ends handles 13. This nook carrying bar is adapted to fit into the slots at the rear ends of the nooks and may be tapered for such purpose. Slits 14 in the neck locking bar receive the aligning ribs IS on the nooks which are conventional. The nooks are secured in aligned position by the nook locking bar 16 having recesses 17 for the nooks and the clamping bar is hinged at one end to the support and the opposite end cooperates with a lock 18.

In the embodiment of FIGURES 6 and 7, the support is in the form of an open ended tube 19 having slits 2% at its outer end and provided with a locking ring 21.

A nook receiving cap 22. has a slit 23 for the nook rib and is pivoted at 24 to the inner end of the tube.

In the operation of FIGURES l to 5, the nooks are assembled on the nook carrying bar with their aligning ribs in the slits 14. The bar .12 is partialy rotated to position the nooks in the recess 11 of crossbar 1t and the nook clamping bar is moved into clamping position and locked in place. The shafts of the arrows are placed in their grooves and positioned to have their longitudinal alignment with the nooks, glue applied to the shafts or nooks, and the shafts with their grain in longitudinal alignment With the nooks pushed into the nooks. The clamping blocks are moved into locking position and retained therein until the glue has set or dried.

The operation in FIGURES 6 and 7 in its broad aspects, are the same as in the previous figures. The nooks are assembled in the nook carrying cap in aligned position. The shaft is aligned in its tube support and glue applied and the shaft pushed into the nook and locked in aligned position by moving the locking ring over the slits in the ring.

Having thus described my invention, What I claim as new and desire to secure by letters patent is:

A nook setter comprising a support having a plurality of longitudinally extending grooves, a crossbar on the support having recesses in alignment with said grooves, nook carrying means to move nooks into aligned position in said recesses, means to clamp the nooks in said recesses, said grooves being adapted to receive the shafts, means to align said shafts in their grooves to have their longitudinal axis in longitudinal alignment with the nooks, and means to clamp the shafts in their aligned positions, wherein the nook clamping means comprises a bar hinged at one end to said support and means on the support to lock the other end of the clamping bar in locked position.
