10 Claims, 9 Drawing Figures PATENIEU FEB 1 ems SHEEI 2 BF 3 PATENIED FEB 1 8 ms sum 3 OF 3 1 WHIP FINISHING TOOL BACKGROUND OF INVENTION The invention relates to tools used as an aid to an- I glers in tying flies and, more specifically, in securing the tying thread to the hook shank and forming what is known as a whip finishing knot, see for example, US. Pat. No. 2,899,226.

Various tools have been proposed and some are being successfully used by anglers for tying flies. Generally the use of these tools are fairly difficult to master and require considerable skill and training to produce quality .fiy heads. Some are peculiarly designed for either'right hand or left hand users and for small and large hooks.

SUMMARY OF INVENTION Another object of the present invention is to provide a whip finishing tool which is equally applicable to either right or left hand users and which in a single size, may be used for tying of various size hooks.

The invention possesses other objects and features of advantage, some of which of the foregoing will be set forth in the following description of the preferred form of the invention which is illustrated-in the drawings accompanying and forming part of this specification. It is to be understood, however, that variations in the showing made by thesaid drawings and description may be adopted within the scope of the invention as set forth in the claims.

DETAILED DESCRIPTION OF INVENTION The whip finishing tool of the present invention com prises briefly a rigid slender element 11, such as steel wire, having a substantially straight free end portion 12 with a hook 13 formed at its free end; a substantially straight intermediate portion 14 having one end 15 connected to and extending laterally from the opposite end 16 of portion 12; a U-shaped intermediate portion 17 having one end 18 connected to the opposite end 19- use of the tool, end portion 12 and intermediate portion 14 form an included angle of less than As will be seen in the later description of the use of the tool, this angulation of portion 14 forms an inclined ramp over which the thread may slide into the channel formed by the U-shaped intermediate portion 17, see FIG. 3.

As will also be observed from the drawings, intermediate portion 17 is composed of a pair of legs 23 and 24 positioned in a substantially common plane with hook 13, end portion 12 and intermediate portion 14. These legs are joined at one end in a loop portion 26 and have their opposite ends 18 and22 connected to ends 19. and 27 of portions 14 and 21, respectively. It will further be noted that legs 23 and 24 are substantially parallel to eachother and to end portion 12 with the open end 28 of thethread receiving channel defined by the legs opening in the same direction as hook l3. Further,'and as an aid to retaining the thread within the channel, see FIG. 4, et seq., loop portion 26 is preferably offset from legs 23 and 24 in the direction of end portion 12, thus trapping the thread within the offset loop when the thread is under tension as shown in FIGS. 46.

As a further feature of the present construction, end portion 21 extends away from the U-shaped intermediate portion 17 at substantially right angles, thereby forming a convenient axis of rotation of the, tool around the hook shank 31 when in use. As a further aid to such manipulation of the tool, the handle forming end 21 is preferably disposed ina plane substantially coincident with end portion 12, and legs 23 and 24 of intermediate portion 17. Finally, to facilitate the proper rotation of the tool around the shank 31 of-the hook being tied, a manually engageable sleeve 32 is here mounted in surrounding relation to end 21 for journalling the latter for rotation. Enlargements 33 and 34 are preferably provided on end 21 at the opposite ends of sleeve 32 for centering sleeve 32 on end 21 and providing finger engaging stops to restrain relative rotation.

OPERATION The fish hook 36 to be tied is fastened in the usual manner in the jaws of a conventional hook supporting vise 37 with the hook shank 31 projecting generally horizontally therefrom as depicted in the FIGS. 1-9.

Fly tying thread 38 carried by bobbin 39 is wound around shank '31 to initialling position and secure hackle 41 in desired position on the hook. The tool of the present invention will then be used to complete the tying of the hackle and a forming of the conventional whip finishing knot. After the hackle or material has been initially secured, as shown in FIG. 2, bobbin 39 will be held in the left hand 42 of the user while the tool handle 32 is engaged by the right hand of the user, assuming the user'to be right-handed. For left-handed persons, the hand position may be reversed. The first step is to engage hook 13 under thread 38 drawing the latter upwardly, as shown in FIG. 2, while a length of thread is payed out from bobbin 39. Due to the angularities and spacial relationship of the parts above explained, the tool will automatically orient, i.e., rotate, to the position shown in FIG. 2. The tool is then rotated 180 using finger pressure against enlargement 33 and- /or against the U-shaped intermediate portion 17,-and, at the same time, moving the tool downwardly with respect to the hook and moving the thread laterally to the right, as seen in FIG. 3, so as to slide over the inclined intermediate portion 14 and into the entry slot 28 of the U-shaped portion 17. The thread 38 is then elevated in the slot with the bobbin moved back to the left, as seen in FIG. 4, with the thread 38 generally paralleling the hook shank 31. As will be clear from the foregoing description of the parts, the tool-will assume a stable rotated position as seen in FIG. 4. In this position, it is important to note the triangle formed by the thread and composed of an altitude dimension 46 extending generally perpendicular to hook shank 31 between the shank and the tool hook 13, a base dimension 47 extending between hook 13 and loop 26 and a hypotenuse dimension 48 extending from loop 26 and alongside of book shank 31. The offsetting of loop 26 in the direction of hook 13 tends to keep the thread in the loop so long as the thread is taut. The size of the thread triangle is controlled andmay, from time to time, be adjusted by the user, by the amount of thread payed out from the bobbin. 7

The next step, as shown in FIG. 5, is to effect a winding of the altitude side 46 around the tool shank and at the same time around the parallel drawn thread side 48. This may be readily accomplished by merely rotating the tool handle in a circle clockwise around the axis of the shank. With such rotation, thetool head will automatically rotate to position the plane of end 12, intermediate portion 14, and U-shaped portion 17, radially of the axis of rotation; and during such rotation, the user can control the thread leaving the bobbin so as to in turn control the size of the thread triangle. With the triangle, the user can swing the altitude thread 46 over the hackle, around the wing and otherwise manipulate the thread to best tie down the fly and at the same time form the multiplicity of loops 51 around the hook shank and thread side 48 as required for forming the whip finishing knot.

When the desired number of loops 51 have been formed as illustrated in FIG. 6, the user will place his left thumb 52 or other finger against loops 51 to retain the thread in position while disengaging the tool. Such disengagement may be easily effected by relative displacement of the tool and thread as illustrated in FIGS. 6 and 7. When the tool has been so disengaged, tool hook 13 is engaged with the thread loop formed by the excess thread on removal of the tool, finger 52 is withdrawn from the loops 51, and the right and left hands of the user are moved apart so as to place the thread, including loop 53, under tension. The thread controlled by the users left hand and depicted at 54 in FIGS. 8

and 9, is drawn to the left, as seen in the drawings, thus reducing the size of loop 53. During such loop reduction, some'force is maintained by the users right hand, which keeps loop 53 taut as it is drawn down to the hook shank. As the loop is reduced to nothing, hook 13 is slipped out of the loop and thread 54 drawn to complete a clean finish at the right-hand end of loops 51,

as viewed in FIG. 9. Thread 54 may then be severed at.

the left-hand end of loops 51 so as to complete the whip finishing knot.
