6 Claims.

This invention relates to a device for attaching a gut or other snell to a fish hook.

One of the objects of the invention is 'to provide an improved and simplied mechanism for controlling the operation of such a device in such a manner as to accurately control the Winding of the binding thread over the hook shank and gut with simplified means of adjustment by means of which the length of the binding can be readily adjusted for various sizes of hooks.

A further object of the invention is the provision of simplified and more ecient means for holding the hooks in the machine during the binding operation together with simplified means for adjusting the device for dilerent sizes of hooks. k

A further object is the provision of improved and simplified means for accurately advancing the hook during the Winding operation proportionally with the Winding operation, so as to assure a uniform wrapping of the binding thread upon the shank, associated with adjustment means rendering the same adaptable to various sizes of hooks.

A further object of the invention is to consolidate and simplify in a unified mechanism the device for automatically stopping the machine at the conclusion of the winding operation, and the means for adjusting the length of the winding operation. Y

The invention consists in the novel construction, arrangement, and combinations of parts, hereinafter more particularly described and claimed.

Referring tc the drawings, which illustrate a practical embodiment of the present invention,

I indicates a substantially rectangular base upon which are mounted Vertical standards 2 2 pro# vided with suitable journals to receive a main ro- -5i tary shaft 4 v.extending longitudinally of the base.

A third vertical standard 3 is positioned on the base at one end in substantial alignment with standards 2 2.

The shaft 4 at one end extends beyondthe nj adjacent pedestal 2 and has mounted thereon a lfreely rotatable pulley 5 provided with an annular clutch flange 6 and secured on the shaft by suitable washers l and 8 by a collar 9 secured on the shaft by a set screw 9. A clutch member 15' I0 is slidably mounted on shaft 4 as by feather II between the adjacent pedestal and pulley 5. The clutch member -Ill is provided with a plurality of radial fingers I2 adapted to engage the annular clutch iiange 6 of pulley 5' and the' 420 clutch is provided with a peripheral groove I3 in which isfpositionedfring I4 secured to clutch lever I5 which is pivotallysecured to the base as by screw I6. A resilient arm I1 is rigidly secured to the base as by screw I8' and its upper r5,35

end engages the hub of clutch I0 so as to `damp the rotation of the clutch upon the release of the clutch. A collar I9 is xedly secured to shaft 4 as by set screw 20, to secure the clutch j and pulley assembly with respect to the adjacent '30 pedestal 2.

Onthe opposite end of the main shaft 4 is slidably mounted a sleeve 2| having at its ends peripheral ilanges 22 and' 23. -A ring 21 surrounds sleeve 2I being associated with arm 28 35 which terminates in ak threaded boss 29. The ring 27 is secured against axial movement on sleeve 2I by collar 24, secured on the sleeve as by set screw 25. l v

The threaded boss `29 of arm28 isthreadedly 40 mounted onthe threadedportion of a rod 30 which is slidably mounted parallel with main shaft 4 in adjacent standards 2 and 3. 'Ihis rod 30 has on its inner end ya` cam follower 36 and the boss 29 is provided with a set screw 3|, by 45 means of which itsadjustment upon the threaded shaft 30 can be secured. A coiled spring 32 is positionecl'on the rod 30 between pedestal 3 and across pin 3| by means of which rod 30 is resiliently pressed in the direction of cam fol- 50 lower 36. The outer end of rod 30 is provided with a threaded section upon which is mounted lock nuts 34 and the rodis further provided with a knurled knob 35 by means of Which it can Y be adjusted. f Y N55 A resilient bumper 33 is positioned on rod 30 between lock nuts 34 and standard 3.

On the outer end of sleeve 2| a lug 31 is secured to flange 23 and the lower end of this lug projects into an axial slot 40 in the free end of shaft 4. A hook engaging hood 4| having a hook engaging slot 42 with an inclined bottom 43 is adjustably secured to flange 23 by means of screws V38 positioned in slotted flanges 39 which extend on opposite sides of hood 4|.

The hook H as indicated by dotted lines in Figure is adapted to be .positioned with its shank in slot 40 and the hook part resiliently held in the slot 42 of hood 4| by means of the inclined bottom 43 of said slot. The entire sleeve 2| with its associated hood 4| is slidable upon shaft 4, and is rotated with the shaft by the engagement of lug 31 in the slot 40.. Sliding of sleeve 2| upon shaft 4 will feed hook H outwardly with respect to shaft 4 within the slot.

The shank of the hook H is held in shaft 4 near its outer end by a pin 9D slidably mounted in the shaft transversely of slot 40. This pin 80 has a rounded inner end and is resiliently pressed across slot 48 as by spring 9|.

. Positioned on base intermediate standards 2- 2 and in transverse alignment with shaft 4 are two standards 5-50, upon which is mounted transverse cam shaft 5| upon one end of which is mounted cam 52 secured as by set screw 53, which cam `is positioned to engage cam follower 36 on the end of rod 30. Between standards 50-50 a worm gear 54 is freely mounted on cam shaft 5| and this worm gear 54 engages a worm 55 formed on shaft 4. The worm gear 54 is provided with an ilo posed dogs 66 biased by springs 6|. secured to posts 52 against the gear teeth 51. Mounted on cam shaft 5| and also between standards 50-50 are two similar cam discs 68 and 65, one of which, 68, islfixedly secured to cam shaft 5| as by set 4,5 screw 64 and the other, formed as an annular flange on sleeve 66, is rotatable with respect to shaft 5|. Both ofthe cam discs 68 and 65 are formed with similar high and 1ow portions 66' and 61', which are semi-circumferential in extent so that by varying the angular adjustment of these two cam discs with respect to eath other the relative lengths of the effective high and .low cam portions of the two discs regarded as a common cam can be modified as desired. On the outer end of sleeve 66 isan annular flange 61 provided with a plurality of spaced orifices 90 arranged circumferentially. On thek outer end of cam shaft 5| is a disc 69 having a flange 16 and GO fixedly secured to shaft 5| as by set screw 1|.

The disc 69 is provided with an orifice 12 threaded to receive a screw 13 having a knurled head 14, which screw 13 is adapted to be selectively entered into one of the spaced orifices of flange 61 .6,5 by which means it will be apparent that the ro- 13 will operate to rotate combined cam discs 68--65 in unison, such rotation, however, being possible only in one direction by reason of the ratchet and dog connection between disc 58 and worm wheel 54. The cam discs 68-65 are en- ..,5 gaged by a common cam follower mounted on a rod 15 slidably supported in standard 2 and connected to clutch lever I5 as `by pin 16.

In operation it will be observed that the rotation of disc or control wheel 69 will rotate cam discs 68-65 from the inoperative position of the machine, in which cam follower 14 is set against the low cam surfaces and clutch ID is disengaged from pulley 5 tobring the yhigh cam `.surface in contact with'cam follower 14?' and thus engage clutch Illand start the rotation of shaft 4 which will continue until the follower 14 again drops against the low cam surface. It will further be observed that the relative lengths of the high and low cam surfaces can be adjusted by means of the same control wheel 69 by adjusting same annularly with respect to flange 61 thus modifying the angular relationship of discs 68-65.

A pinA 18 mounted on the base is adapted to receive a spool S containing the thread T for use with themachine and the spool S is damped by `means of a coiledspring 19 secured againstvsame as by pin 80 passing through post 18. The thread T is extended from spool S through a guide coil 8| secured to the base and thence between hard polished washers 82 mounted on a post 83 secured to pedestal 3'by a bracket 81. 'Ihe tension of the washers 62 is controlled by a compression spring 84, the force ofwhich is adjustable by means ofcottapin 85 and its selective insertion into one of a plurality of holes 86 in rod 83. From washers 82 the thread is extended through a slot 88 in the bracket 81.

Theend of the thread is given a counterclockwise turn about the. shank of the hook and associated gut and then. passed under a tension linger 45 secured in the end of shaft 4 and provided with afknifeedge 45', which can be used at the conclusion of the wrapping operation to sever the thread T, preliminary to a repeat operation.

In operation the fishl hook to be snelled is placed with its shank in slot 40 and with the hook caught under anvil 4l as indicated in Figure 5. The thread T is carried from spool S through the guide 8| and between the washers 82 and under the catch onthe end of the shaft. `A length of gutor cord is then placed in slot 4l) over the hook shank.

Byturning disc 69 by hand spoke 11, shaft 5| is then rotated until the cam formedby the cornbined discs 65 and 68 engages roller 14 thus en- 4gaging the main clutch Wand starting the inachine. The machine continues operation as long as that cam rides against roller 14, which will be determined by the size of the cani, which in turn, is determined as previously pointed out by the angular relationship of cam discs 65 andGB.

During the operation of the machine the cam 52 will bear against follower 313, thus propelling carriage 2| outwardly and providing for the even spiralwinding of the threadfaround the superposed shank and gut.

As previously indicated, the drawingsherein represent a practical embodiment of the invention but Various modifications will readily suggest themselves to those skilled in the art but within the scope of the invention as claimed.
