8 Claims.

This invention relates to a machine for forming leaders for fishing equipment, the general object of the invention being to provide means for forming loops at the ends of each leader with portions of the wire wrapped or coiled closely about the twisted portions which form the shank of the loop.

Another object of the invention is to make the parts adjustable so A further object of the invention is to provide means whereby fish hooks, swivels or other objects can be connected with the looped ends of the leaders while the loops are being formed.

This invention also consists in certain other features of construction and in the combination arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in Which Figure 1 is a top plan View of an apparatus constructed in accordance with the invention.

Figure 2 is a section on the line 22 of Figure 1.

Figure 3 is a section on the line 33 of Figure 1.

Figure 4 is a section on the line 44 of Figure 2.

Figure 5 is a fragmentary plan view showing the means associated with one of the spindles and a portion of the cam carrying shaft.

Figure 6 is a view showing the spindles with the wire extending between the same, the guides and the means for holding objects so that they will be connected with the looped ends of the wire.

Figure 7 is a View partly in section of one of the looped ends of a leader.

Figure 8 is a fragmentary view showing how a swivel is connected with the looped end of a leader while the loop is being formed.

In these views the letter A indicates an upright frame or table having a skeleton top and a shelf I resting on an intermediate part of the top and is adapted to be adjusted toward or away from the end 2 of the table top, any suitable means being provided for holding the shelf in adjusted position. A shaft 3 extends longitudinally and slightly above the table top and is jourtable top at the front thereof second rod 1 is adjustably held members is formed with the 1 cross piece 26.

naled to the end parts thereof as shown at 4 and an intermediate part of the shaft is journaled to the shelf I as shown at 5, this bearing 5 permitting the shaft 3 to slide through it as the shelf is being adjusted. The shaft carries a pair of cams 6 which have their cam faces facing toward the ends of the table top. A rod 1 extends longitudinally of the table and is adjustably held in a sleeve 8 on the rear end of the shelf I and a in a sleeve 8 on the end part 2 of the table. Levers 9 have their rear ends pivotally connected to the adjacent ends of the

rods

7 and 1 as shown at ID, the levers extending across the table to a point adjacent the front thereof where said levers have the projections II at the front ends. The cams 6 are adjustably connected to the shaft 3 by a screw I2, see Figure 5, and a pin I3 is carried by each lever for engagement by the cam face of the cam as also shown in Figure 5. A pair of supporting plates I4 is slidably arranged on the and between the shelf I and the end part 2. A pair of rods I5 is pivotally connected with each plate as shown .at I6 and the rods of the right hand plate in Figure 1 pass through the horizontally arranged tubular members I1 on the shelf I while the rods of the other plate pass through the tubular members I1 on the end part 2. Each of the tubular lubricant receiving means I8 whereby the rods can be lubricated and the ends of each pair of tubular members are connected together as shown at I9 and the outer ends of the rods are connected together by a A spring 2| connects each cross thus the plates I4 will be held yieldingly against the projections II of the levers 9 but when the front ends of the levers are moved apart by the cams 6 these plates I4 will be moved apart and against the tension of the springs 2!. Each plate I4 has a trackway 22 therein which extends transversely of the table top and a small slide or carriage 23 slides in this trackway. A resilient bumper 24 is fastened in the outer end of each trackway and a cable 25 has one end connected to a part of the carriage or slide 23 and the cable passes over a pulley 2B in the outer end of the plate I4 and said cable has a weight 21 attached .to its lower end so that this weight acts to hold the carriage or slide 23 in its outward position or in a position engaging the bumper 24. The

carriage is formed with a member 28 which forms a stationary jaw of a clamp, the movable jaw 29 of which is formed on the inner end of a lever 30 pivoted to the carriage as shown at 3| with the parts of arcuate shape. A spring the outer end of the lever 3|] with a stationary rod-like member 33 attached to the carriage and this spring 32 acts to hold the jaw 29 in clamping engagement with the stationary jaw 28 so as to grip one end of a wire W on the carriage. of course, when the lever 30 is swung away from the member 33 and against the action of the spring 32 the jaw of the wire.

A bracket 34 depends from the inner end of each plate l4 and an arm 35 is pivoted to the lower end of the bracket and carries a socket 36 at its free end for receiving the lower end of a post 31 which is held in the socket in any suitable manner and a cable 38 is attached to the socket and has a weight 33 at its lower end, this weight acting to hold the arm 35 in a position with its pivoted end engaging a stop 40 and with the post in vertical position. However, these parts are so arranged that the post can be swung in a direction toward the inner end of the plate |4 when desired, it being seen that the arm 35 projects beyond the inner end of the plate l4 so that the post is spaced from said inner end as more clearly shown in Figure 5. The upper end of said post has a slot 4 therein which is in alignment with the gripping face of the jaw 28 so that when a portion of the wire is passed through the slot said wire will extend in a straight line from. the post to between the jaws.

A spindle 42 is slidably and: rotatably supported by the shelf and a spindle 42 is rotatably supported by the end part 2 but this spindle 42 cannot slide or move longitudinally. The spindle 42 passes through the bearing members 43 and a collar 44 is attached to the spindle between the bearings and a spring 45 has one end bearing against the front bearing and its other end against the collar so as to hold the spindle 42 in a rearward position or in a position where it will be farthest from the spindle 42. The adjacent ends of the two spindles are formed with needle-like parts 46 which have their ends bent to form hooks 41. The spindle 42 is connected by a chain and sprockets shown generally at 50 to a longitudinally extending shaft rotatably supported on a lower horizontal part A of the frame. A stub shaft 52 is supported by this part A and a pinion 53 on the shaft 5| meshes with a gear 54 on the stub shaft while a belt and pulley arrangement 55 connects the stub shaft with the shaft 3 so that the shaft 3 is driven at a different speed from the shaft 5|. At the other end of the main frame the shaft 5| has a large pulley 55 attached thereto over which a belt 51 passes which also passes over a small pulley 58 of a motor M supported on a shelf 59 in the frame. The shaft 5| has a gear 60 connected therewith which meshes with a gear 6| on a shaft 82 which also has a'sprocket wheel thereon over which a chain 63 passes and which chain passes over a sprocket on the spindle 42. The gearing is preferably interchangeable so that the spindle 42' can be made to rotate in an opposite direction from the spindle 42 be made to revolve in the same direction. A push button switch or other type of manually operated switch 64 is provided at the front of the frame for controlling the circuit to the motor M and a mercury switch 65 controls or the two spindles can 29 will release the end 1 passes over the hook 41 of portion of mercury switch to close 50 from. the hooks circuit to the motor. A cam 66 is arranged on the shaft 3 for controlling the position of the switch and the parts are so arranged that the switch 65 will be moved to close the circuit after the motor has been started by the closing of the switch 64. Then the switch 64 can be released and the circuit to the motor will remain closed by the switch 65 until the cam 66 reaches a certain position when the switch 6-5 will break the circuit and stop the motor.

A hand lever 61 is pivoted to the bracket 68 on the shelf and said lever when moved to the left in Figure 5 will engage a part 69 on the spindle 42 so as to push the spindle 42 forwardly or toward the other spindle so as to slacken the wire between the spindles.

Each spindle carries a socket forming member 10 for a hook rod 1| which is held in position by a set screw 12. These hook rods are adapted to hold objects, such as the fish hook 13 or the swivel 14 in position to be engaged by the loops to be formed when it is desired to connect the leader with an object.

As shown in Figure '1 this device will form a loop a in each end of the leader wire 112 with the parts adjacent each loop twisted together. as at a. and then the wire is closely wrapped or coiled about the twisted part as shown at a".

As shown in Figures 1, 5 and 6, one end of the wire W is held between the clamping means 28 and 29 of the carriage on one of the slides or plates M with the wire passing through the slot 4| of the post 31 of the plate and then the wire the spindle 42 and then the wire passes over the hook of the spindie 42 through the slot 4| of the post 31 of the other plate l4 and is then held between the clamping means of said other plate |4. Thus a the wire is stretched between the two spindles with portions adjacent the hooked ends of. the spindles passing through the slots of the posts. The weights 21 connected with the carriages or slides 23 hold the wire taut.

. The motor is then started by switch 64 which starts to rotate the spindles and said spindles revolve a plurality of times to one revolution of the shaft 3. After the motor has rotated the spindles a few revolutions cam 66 will cause the the circuit to the motor which keeps the machine operating until the desired number of turns of wire has been wound and the contact is broken automatically as the cam 66 again raises the mercury switch to break the circuit.

The parts are so timed that when the machine stops the pins |3 on levers 9 are at the high parts of the cams 5 so that the plates M are adjacent their innermost positions with the posts spaced of the spindles a distance substantially the length of the twist a. Then the switch 64 is closed to start the motor which turns the spindles and this results in forming the loops a by twisting the wire as at a. This also results in turning shaft 3 to place the cams 6 to cause the the twists a so that the wire will :34 during this movement so a pins l3 to engage the low parts of the cams and to close switch 55. Then the cams 6 act on the levers 9 to move the plates |4 away from each other and this causes the posts to move slowly along be coiled around the twisted parts beginning fromv that end of the twisted part a farthest from the loop to the base of the 1001).. Then the posts 31 are swung toward the plates M, the arm 35 pivoting on the bracket that the post will be spaced from the twisted part of the wire to facilitate cutting the wire close to the outer end of the twisted part a". Thus a loop Wrapped around the twisted part thereof after the twisted part has been formed.

As before stated, this invention is mainly de I signed for forming loops at the ends of leaders used in fishing equipment but it can be used for other purposes.

The spindles can be made to rotate in opposite directions when the leader is formed of multiple strands of that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in he construction and in the combination appended claims.

Having described the invention, What is claimed as new is:

around the twisted parts.
