[0006] In fishing, especially the art of fly fishing, to be successful, the fisherman must be able to change to different flies, hooks or similar article depending on the water conditions and upon what insect or hatch the fish are feeding on. During the course of time on the water, the angler may change flies, hooks, or similar article many times. Because of these numerous changes, it is desirable to be able to tie a secure knot in a timely and efficient manner. Each time the fly, hook or similar article is changed, the leader or line is shortened. To decrease tying time and minimize this loss of line or leader, a convenient and easy to use tool needed to be invented.

[0007] A number of special devices have been suggested for assisting anglers and others in the knot tying process. Most of the present, knots tying devices require the mechanical or manual sliding of the leader or line from some object such as a nail or tube onto a leader or line. This invention does not require such a transfer. Descriptions of some of prior art knot tying devices are contained in the following list; whish list is not all-inclusive but merely representative.

[0018] The Fisherman's knot tier, in accordance with the present invention, includes, in general, two elongated hollow bodies or barrels joined together by circular internal and external threads or an overlapping glueable joint and reductions in diameter with a coil expansion spring-mounted tubular piston or shaft, and a second piston/push button therein and an alligator clip or modified alligator clip/cutter mounted thereon.

[0019] The upper barrel has internally mounted threads or an overlapping glueable joint at one end of the elongated hollow body. The upper barrel also contains a terminal bore located longitudinally and centered at the distal end of the barrel from the internally-mounted threads or overlapping glueable joint. This terminal bore located therein creates a shoulder. An alligator clip or modified alligator clip/cutter is attached to the outer surface of the upper barrel near the terminal bore.

[0020] The lower barrel has externally recessed threads or a reduction in diameter located at one end of the elongated hollow body. The recessed threads or a reduction in diameter also creates a shoulder. A tapered end is located longitudinally on the distal end of the lower elongated hollow body from the externally mounted recessed threads or reduction in diameter. The lower elongated hollow body also has a longitudinal terminal bore at the tapered end of the body. The terminal bore located therein creates a shoulder. The lower barrel may or may not have a rubber finger grip attached to the outer surface. The lower barrel may or may not contain an insert in the tapered end of the barrel.

[0021] The upper and lower barrels have two pistons slidably mounted and constrained within them.

[0022] The coil expansion spring-mounted tubular piston or shaft housed within the upper and lower barrels, has lug members or a stop located near one end of the tubular piston or shaft and a slot located near the same end of the tubular piston or shaft. The slot is cut to a depth of ½ to ⅔ the diameter of the tubular piston or shaft. This slot is at an incline less than 90 degrees measured from the long longitudinal side of the tubular piston or shaft. The end opposite the slotted end of the tubular piston or shaft fits into a bore in the second or upper piston.

[0023] A coiled expansion spring encircles the slotted end of the tubular piston or shaft. One end of the coiled expansion spring abuts the lugs or stop on the tubular piston or shaft and the other end abuts the shoulder created by the terminal bore, or the shoulder of an insert, if so equipped, in the lower elongated hollow body.

[0024] The upper piston housed within the upper and lower barrels has a bore centered and extending on the longitudinal axis into one end of the upper piston a short distance. At the opposite longitudinal end of the piston, a reduction in diameter creates a shoulder and push button.

[0025] The clip/cutter, in accordance with the present invention, in general, is a modified alligator clip with cutting surfaces thereon. The clip/cutter consists of two jaws hinged together by a common pivot pin, with suitable ears being provided to hold the pin and the ears are extended to provide U-shaped arms for a continuation of the jaws. The U-shaped arms are to actuate the jaws and incorporate the cutting edges. A coil spring, wound around the pivot pin, has opposite ends in contact with each of the U-shaped arms to keep the jaws in bias and towards each other.

[0026] The U-shaped jaw on the upper half of the clip has serrated teeth to aid in holding a fishhook or similar article therein, or clipping the Knot tier in a shirt or vest pocket. The U-shaped arm of the upper half of the clip has two cutting surfaces that may be flat or ground at an incline to the horizontal axis of the jaw located thereon.

[0027] The jaw on the lower half of the clip is smooth and curved to allow for easy attachment of the clip to the upper barrel and aid in holding a fishhook or similar article therein, or for easily clipping the Knot tier in a shirt or vest pocket. The U-shaped arm of the lower half of the clip has two cutting surfaces that may be flat or ground at an incline to the horizontal axis of the U-shaped arm.

[0041] FIG. 6 A successive schematic diagrams illustrating the knot tying process using the Fisherman's Knot Tier.

[0042] Referring now more particularly to the drawings, reference numerals are used to denote like parts or structural features in the different views. While a particular embodiment of the invention has been shown and described, it will be understood that the invention is not limited hereto, since modifications may be made that will become apparent to those skilled in the art. A knot tier 60, embodying the principles of the present invention, is shown in FIGS. 1-5 of the drawing to illustrate the presently preferred embodiment of the invention. The Fisherman's knot tier 60, in accordance with the present invention, includes, in general, two elongated hollow bodies, or barrels 1 and 20. The two barrels 1 and 20 are joined together by circular internal 2 and external 22 threads or an overlapping glueable joint 12 and a reduction in diameter 13 with a coil expansion spring-mounted lower tubular piston or shaft 23 and a second upper piston 3 therein and an alligator clip or modified alligator clip/cutter 40 mounted thereon.

[0043] The barrels 1 and 20 have two pistons 3 and 23 slidably mounted and constrained within the two elongated hollow bodies or members 1 and 20.

[0044] The upper barrel 1 has internally mounted threads 2 or an overlapping, glueable joint 12 at one end of the elongated hollow body 1. The upper barrel 1 also contains a terminal bore 4 located longitudinally and centered at the distal end of the barrel 1 from the internally mounted threads 2 or an overlapping, glueable joint 12. This terminal bore 4 located therein creates a shoulder 5. An alligator clip or modified alligator clip/cutter 40 is attached to the outer surface of the upper barrel 1 near the terminal bore 4.

[0045] The lower barrel 20 has externally-recessed threads 22 or a reduction in diameter 13 located at one end of the elongated hollow body 20 and the recessed threads 22 or a reduction in diameter 13 also create a shoulder 24. A tapered end 26 is located longitudinally on the distal end of the lower elongated hollow body 20 from the externally mounted recessed threads 22 or a reduction in diameter 13. The lower elongated hollow body 20 also has a longitudinal terminal bore 25 at the tapered end 26 of the body 20. The terminal bore 25 located therein creates a shoulder 28. The tip 27 of the lower barrel 20 may be formed by a cone or insert.

[0046] The tubular piston or shaft 23 has lug members or stop 31 located near one end 29 of the tubular piston or shaft 23, and a slot 30 located near the same end 29 of the tubular piston or shaft 23. The slot 30 is cut to a depth of ½ to ⅔ the diameter of the tubular piston or shaft 23. The slot is cut at an incline of less than 90 degrees measured from the long longitudinal side 32 of the tubular piston or shaft 23. The end 6 opposite the slotted end 29 of the tubular piston or shaft 23 fits into a bore 7 in the upper piston 3.

[0047] The upper piston 3 has a bore 7 centered and extending on the longitudinal axis into one end of the upper piston 3 a short distance. At the distal longitudinal end 11 of the upper piston 3, a reduction in diameter 9 creates a shoulder 8 and push button 10.

[0048] A coiled expansion spring 21 encircles the slotted end 29 of the tubular piston or shaft 23. One end of the coiled expansion spring 21 abuts the lugs or stop 31 on the tubular piston or shaft 23 and the other end abuts the shoulder 28 created by the terminal bore 25 in the lower elongated hollow body 20 or the end of the insert 27.

[0049] When the button 10 is pressed, the longitudinal transfer of motion to the tubular piston or shaft 23 causes the lugs or stop 31 on the tubular piston or shaft 23 to exert pressure on one end of the coil expansion spring 21. This longitudinal transfer of motion in turn depresses the other end of the coil expansion spring 21 against the shoulder 28 of the terminal bore 25 within the lower elongated hollow body 20 or the end of the insert 27. This continued transfer of motion forces the slotted end 29 of the tubular piston or shaft 23 to protrude beyond the distal end, cone or insert 27 of the lower elongated hollow body 20.

[0050] When pressure on the button 10 is released the opposing longitudinal transfer of motion created by the coil expansion spring 21 against the shoulder 28 of the terminal bore 25 within the lower elongated hollow body 20 or the end of the insert 27, and longitudinal transfer of motion against the lugs or stop 31 on the tubular piston or shaft 23 created by the coil expansion spring 21, cause the tubular piston or shaft 23 to recede back into the lower elongated hollow body 20. When this transfer of motion is completed the slot 30 located near the tip, cone or insert 27 of the tubular piston, or shaft 23, will no longer protrude beyond the tip, cone or insert 27 of the lower elongated hollow body 20.

[0051] A clip/cutter 40, in accordance with the present invention, in general, is a modified alligator clip 40 with cutting surfaces 46, 56, 48, and 58 thereon. The clip/cutter 40 consists of two jaws 41 and 42 hinged together by a common pivot pin 44, with suitable ears 43 and 53 being provided for that purpose. The ears 43 and 53 are extended to provide U-shaped arms 47 and 49 for a continuation of the jaws 41 and 42. The U-shaped arms 47 and 49 are to actuate the jaws 41 and 42 and incorporate the cutting edges 46 and 56 with cutting edges 48 and 58. A coil spring 45, wound around the pivot pin 44, has opposite ends in contact with each of the U-shaped arms 47 and 49 to keep the jaws 41 and 42 in bias and towards each other.

[0052] The U-shaped jaw 41 on the upper half of the clip 40 has serrated teeth 50 to aid in holding a fishhook or similar article therein or for clipping the Knot tier 60 in a shirt or vest pocket. The U-shaped arm 47, of the upper half of the clip 40, has two cutting surfaces 46 and 56 that are flat or may be ground at opposite inclines to the horizontal axis of the upper jaw 47 located thereon.

[0053] The jaw 42 on the lower half of the clip 40 is smooth and curved to allow for attachment of the clip to the upper barrel and ease of clipping the Knot tier 60 in a shirt or vest pocket and to aid the upper U-shaped jaw 41 in holding a fishhook or similar article therein. The U-shaped arm 49 of the lower half of the clip 40 has two cutting surfaces 48 and 58 which are flat or may be ground at opposite inclines to the horizontal axis of the lower U-shaped arm 49. The inclines or flat surfaces 46 and 56 of the upper arm 47 and the meshing inclines or flat surfaces 48 and 58 of the lower arm 49 are at the same angle to create a shearing action when the U-shaped upper and lower arms 47 and 49 are forced together.

[0054] When pressure is applied to the upper U-shaped arm 47 of the clip 40, the upper U-shaped arm 47 of the clip 40 is forced toward the U-shaped lower arm 49 of the clip 40 as they pivot around the pivot pin 44. This action opens the jaws 41 and 42, while at the same time forces the cutting edges 46 and 56, and the cutting edges of 48 and 58 of the U-shaped arms 47 and 49 together in a shearing action. When the pressure to the upper U-shaped arm 47 of the clip 40 is released, the opposing pressure caused by the action of the coil spring 45 returns the jaws 41 and 42 to the closed biased position and the U-shaped arms 47 and 49 to the open position.

[0055] This invention has been described in detail with reference to a particular embodiment thereof but it will be understood that various other modifications can be effected within the scope and spirit of the invention. It will also be understood that various omissions, substitutions and changes in the form and details of the device and its operation can be made by those skilled in the art without departing from the spirit of the invention. These might include but not limited to modifications made during manufacture to make each part of this invention workable in the manner for which it is intended.

[0056] The invention can be used in several ways. The following explains four possibilities. Referring to FIGS. 6A through E of the drawings the operation of the invention will be described.

[0057] A. To Tie a Leader or Line to a Hook.

[0058] While holding the knot tier in one hand, place the curve of the fishing hook in the jaws of the clip on the knot tier so the shank and eye of the hook are pointing in the direction of the distal end of the body (FIG. 6A). Thread the line or leader through the eye of the hook (FIG. 6A). With the other hand, grasp the end of the line between the thumb and index finger allowing 1 inch to 1½ inches of the end of the line to protrude beyond the finger and thumb (FIG. 6A). Grasp the other portion of the line in the same hand allowing the two lines to run parallel to the body of the tier with enough line to extend beyond the tip end of the instrument (FIG. 6A). Move the tip so it is positioned between the two parallel lines or leaders (FIG. 6A). While continuing to hold the line turn the entire instrument in a wobbling action around the grip of the two lines, this will allow the two portions of the line to wind around each other (FIG. 6B). (This wobbling motion around an axis is sometimes called nutation.) After completing 5 or 6 turns, depress the push button to expose the slot in the end of the tier (FIG. 6C). Insert the end of the line into the slot far enough to allow a good “grasp” when the push button is released. Hold the line in the slot while releasing pressure on the push button (FIG. 6C). The end of line will be secured between the slot and the end of the tire body. Release the end of the line between the finger and the thumb. Pull on the other portion of the line already secured in the same hand to remove the slack in the line (FIG. 6D). While continuing to pull the line, release the hook from the clip to allow the hook to be pulled toward the tip of the tier as the line is tightened (FIG. 6D). When the eye of the hook reaches the end of the tier hold the hook securely about ⅛ of an inch from the point of the tier (FIG. 6D). While holding the hook at this position, continue pulling the line until the line is securely cinched around the eye of the hook. Release the end of the line secured by the slot and body by depressing the push button. The knot has been tied. The excess line protruding from the eye of the hook can be trimmed by using the clip/cutter. This can be accomplished by placing the end of the line into the cutter at the desired trim length and holding it there while opening the clip (closing the cutter). The line should not be trimmed closer than {fraction (1/16)} of an inch from the eye of the hook.

[0059] B. To tie a leader or line to a swivel.

[0060] Tying a line to a swivel is similar to tying a line to a hook. The only difference is that the swivel needs to be securely held by the jaws of the clip in such a way as to allow the threading of the line through one eye of the swivel.

[0061] C. To tie a leader or line to a lure.

[0062] Tying a line to a lure is similar to tying a line to a hook. The only difference is that the lure needs to be securely held by the jaws of the clip in such a way as to allow the threading of the line through the eye or ring of the lure.

[0063] E. To cut the hook from the line or leader when a clip/cutter is attached.

[0064] Place the eye of the hook close to the cutter so the leader or line is cut when the cutter is activated.
