Th holders it and H ar pr f r bly of s ft rubber each having slots or slits I2 and I3 for resiliently holding the strands it and 1 and l4 may be regard d as the first an e t strand of a tapered leader. Strand Hi is shown of exag erated siz in rder o more re ily distinguish it from the next smaller size of strand. strand M s seemed n e h ders so that its rear end'extends an inch or two to the right of holder H. The iront end of the second strand I5 suitable material and has three wires l1, l8 and [3. The two outer wires I8, [8 are resilient and tapered toward the center wire at their tips as shown in Fig. 8 so as to facilitate tucking the ends of the strands between the wire I1 and wires I8, I 8 as will be hereinafter explained.

The holders and II are mounted in cups 20 and 2| secured on the ends of shafts 22 and 23 which are supported rotatably in the blocks 24 and 25. These shafts have pinions 26 and 21 which are driven from gears 28 and 29 on the counter shaft 30. In order to have one shaft rotate in the opposite direction to the other I employ an idler 3i interposed between one gear and its pinion for instance between gear 29 and pinion 21. The ratio of gear 21 to 25 and 26 to 28 may be conveniently set at 1 to 3 for tying gut and 1 to 4, or vice versa, for tying nylon strands so that a single turn of gear 29 (which has a handle 32) will produce the requisite number of twists in the knot. The gears can be turned by hand or by power if desired.

Shaft 22 is hollow so that a strand can be fed through it and avoid tangling. A hook member 33 may be supported on the end of an arm 34 so that it can slide through shaft 22 to a point accessible near holder 10. Arm 34 is guided in a sleeve 35 and held under bias of a spring 36 against the rubber buffer 31.

At the start of a leader, a loop is tied in any suitable manner on the end of the strand which is to be the line end of the leader. This loop is hooked on to the hook 33 and the arm 34 is pulled to the left by hand thus pulling the first strand length through the hollow shaft 22 but leaving just enough of the strand projecting to the right to enable it to be tucked into the holders i0 and II as above described (see Fig. 4).

The front end of the second strand is then tucked into the holders i0 and H. When the strands are twisted a central eye or loop I6 is thus formed about the central abutment I6. The tips of the strands M and are then pulled out of the slots 52, I2 in the holders and pulled down in place between the wire grippers l8, l8 and ll of Fig. 8 as shown in Fig. 6. The strands l4 and 55 are then slipped out of slots l3, l3 of the holders l 0 and I l and pulled up by hand as shown in Fig. 7, the tips of the strands remaining in the grip of the wire jaws of the abutment. This starts the knot which is completed by pulling the main parts of the strands I4|5 in opposite directions until the tips of the strands are released from the center abutment l6 and the turns of strands are drawn close together. The tips of the strands are then snipped off close to the coil of the knot. By tying the knot in this way both tips come out at the same point as shown in Fig. 9 and can be snipped oif simultaneously.

By dividing the central abutment into two parts for holding the tips of the strands separately and drawing one tip upward through the eye I6 formed at the center by the twisting operation while the other is in effect drawn downwardly I can bring the tips of the strands out on opposite sides of the knot if desired as shown in Fig. 10.

By mounting a reel or drum 40 on the end of gear 28 it is possible to coil up the completed leader without moving from the machine.

A coiling drum 60 may be mounted on the hollow shaft 22 as shown in Fig. 2c and in place of the hook 33 for pulling the first strand through the shaft I may provide a funnel 22 which permits the operator to readily insert the first strand from the left toward the right to engage the 4 holders i0 and H. The drum 40 may be provided with a hook e3 for the attachment of the loop on the end of the finished leader. By rotating the drum ii! the leader can be quickly coiled upon it.

In making tapered leaders it is highly important that the proper sizes be assembled in proper sequence. As examples, I suggest for a medium heavy trout leader successive sizes of .017 0.15", .013", .011 and .009 and for an extra light trout leader .012, .010, .008", .007 and .006". For this reason I provide a series or row of tubular containers 4 I 42, 43 etc. for the bundles of strands each being marked with its size e. g. .016, .113, .111 etc. and arrange them in sequence from left to right across the front of the machine where they are slidable in a guide way 44. At the start all the containers are slid to the right and each is moved to the left as its strand is used. When the leader is finished all the containers are moved back to the right.

The vertical containers for the strands may also be carried by a turntable or drum rotatable on a vertical axis beneath the bench on which the tyer is mounted, the front edge of the drum projecting beyond the edge of the bench so that the containers can be brought into an exposed position in sequence. This drum can be driven by the counter shaft.

When handling gut the containersare filled with water as it is necessary to keep the strands wet while tying the knots. After each knot has been tied the last strand is pushed through the tubular shaftand its rear end tucked into the holders ready to be connected with the next strand and so on till the leader is completed.

As soon as a gut leader is complete it is wound under tension on a drum 40 or 50 which may be heated and left there until set in a coil form. Whereupon it can be immediately tucked in an envelope and placed in a box.

It should also be understood that the heating and coiling of gut leaders may be effected as separate operations.

The machine may be operated by hand as herein shown and described or the gears may be power driven in any suitable manner (not shown) and provided with clutch and control devices so that the rotation may be started by pressing a button or lever and stopped automatically when the desired number of twists have been made.

The two rubber holders are preferably geared together so that they can be driven by one hand as shown or by p0wer-but they could be driven independently.

The rubber holders and the central abutment and wire jaws may also be used without the driving mechanism. In such a case the holders would be held stationary in any suitable base and the abutment inserted between the strands as shown in Fig. 4 and used as a tool for twisting the strands, and then attached to the base while the knot is tied as shown in my Patent No. 2,469,037. 7

By rotating the holders in the same direction to twist the strands, the barrel knot which is formed will have its coils inclined in opposite directions on opposite sides of the center as shown in Fig. 9. By rotating the holders in opposite directions when twisting the strands the coils will all be inclined in the same direction as shown in Fig. 10. When the tips of both strands are pulled through the central eye in the same direction as shown in Fig. 7 the tips will come out together as shown in Fig. 9. By pulling the tips through the central eye or loop of the strands in opposite directions the tips will come out on opposite sides of the knot as shown in Fig. 10.

I claim:

1. In a leader tyer, two spaced holders havin resilient jaws for gripping portions of the ends of leader sections to be joined, means for rotating said holders about a common axis, and a fixed separator holder supported between said jaws having gripping members about which the 1 leader sections are twisted and form an eye and between which members the ends of the leader sections are held while the main parts of the twisted leader sections are drawn over the separator thus passing the free ends through the central eye of the twisted leader sections.

2. In a leader tyer, two spaced soft rubber holders slitted to receive strands to be twisted and an intermediate abutment having means for holding the strands separated to form an eye when the strands are twisted between the holders and having means for gripping the tips of the strands while the twisted strands are pulled from the abutment and the eye of the strands is drawn over the tips to start the knot.

3. In a knot tyer two spaced strand holders each having two resilient jaws to hold short lengths of two strands to be joined, an abutment between said holders with gripping means and means for rotating said strand holders in opposite directions so as to twist the strands about said abutment, and form an eye which can be drawn from said abutment and at the same time draw the tips of the strands through said eye to start a knot.

4. In a leader tyer a pair of spaced holders for holding lengths of strands, an abutment between the holders around which said strands can be twisted, means for creating relative rotation between said abutment and said holders for twisting strands held by said holders, one of said holders having a tubular support and a hook reciprocable through said tubular support for engaging and drawing an end loop of a strand through said support.
