FLY-TYING VISE Filed March 5, 1948 INVENTORS ELTO/V 0. MAYHEW ALBERTWROU/VD ATTX i atented Sept. 25, 1951 UNITED STATES PATENTVOQFFICE Elton C. Mayhew and Albert W. Round, Torrington, Conn., assi'gnors to The SterlingMfg. 00., Torrington, Conn., a corporation of Connecticut Application March 5, 1948, Serial No. 13,095

This invention relates to clamps, and more particularly to a vise for efficiently holding a fish hook during the operation of tying a fiy thereon. :One object of this invention is to provide a device. of the above nature in which the vise jaws are actuated by an eccentric cam member at the -rear ends of the jaws, whereby they may be operated rapidly and efficiently, and the fly-tying operation will not be obstructed.

Another object is to provide a device of the above nature in which, the eccentric cam member. operates against an adjustable abutment,

whereby the jaws may be easily adjusted te clamp L vise as it appears during use.

Fig. 2 is a plan view of the vise jaws, partly in section, showing the eccentric cam member in clamping position.

Fig. 3 is a front end view of the same, as seen from the upper left of Fig. 1.

Referring now to the drawings, in which like reference numerals denote corresponding parts throughout the several views, the numeral II] indicates an angular upright rod which is supported by means of a holding device in the form of a C-clamp H which has a clamp screw l2 adapted to hold the clamp upon the edge of a table, shelf or other horizontal member T. The C-clamp II is provided with a vertical bore l3 within which the rod I is fitted, and has a set screw I4 which is adapted to adjustably hold the upright rod ill in its forward position.

The rod II) has an upper portion l5 which is rearwardly inclined and has a reduced cylindrical extremity l6 which is locked in the apertured rear end of a stationary jaw I! by means of a key-pin l8.

It will be thus seen that the stationary jaw I! is carried in an inclined forwardly-extending position at right angles to the upper inclined portion l5 of the upright rod Ill.

The vise includes a short movable jaw [9 which is attached to a central portion of the stationary jaw ll by a pivot means in the form of a pair 1 Claim. (Cl. 81-25) of plates '20, 2| which carry a pivot pin 22 and are secured to the upper and lower faces, respectively, of the'jaw 11 by means of a pair of rivets 23 passing therethrough. The jaws ll, I3 are of any suitable material such as hard steel, and are preferably provided with a dull finish, whereby annoying reflection of light willbe avoided.

The jaws l1, l9 have

front end portions

24, 25 which have tapered outer sides and rounded ends. The movable jaw I9 is provided with a concave" inner longitudinal gripping groove 21, while the stationary jaw ll has a fiat gripping surface 26. It will be understood that either or both of the front '

end'jaw portions

24, 25 may be provided withconcave grooves'such'as the groove The opposed surfaces of the" front end portions 24, 2 5 are provided just'forwardly of the plates 20, 2|, with a pair of

transverse bores

28, 29 which serve as sockets fora coil, spring 30, by which the

portions

24, 25 will be urged apart.

In order to clamp a fish hook H between the

end portions

24, 25, provision is made of a circular cam member 3| which is eccentrically pivoted in a slot 3m in the rear end of the movable jaw IB by means of a pin 32. The cam member 3| is adapted to coact with an abutment in the form of a ball bearing 33, preferably of steel, which is movably held in a tapped bore 34 in the stationary jaw ll. The periphery of the cam member 3| is provided with a groove 35 having the same cross sectional curvature as the surface of the ball 33, whereby a good bearing engagement may be obtained between the ball 33 and the cam member 3|, and friction will be minimized.

The ball 33 is held in the bore 34 by means of an adjusting backing screw 36 which is located in the outer end of the tapped bore 34, whereby the position of the vise jaws ll, l9 may be adjusted as desired.

Provision is made of a jam nut 31 engaged on the outer portion of the adjusting screw 36, whereby said screw will be locked in adjusted position.

The cam member 3A is provided with a radially-extending handle in the form of a lever 38, which is bent to provide an angular portion, so that when the vise jaws ll, I9 are in position to clamp the fish hook H, the handle 38 will be disposed substantially in alignment with Said jaws and will not obstruct the movements of the operator during the operation of tying a fly F upon the hook H.

Operation centric cam member 3| will produce the desired;

clamping action of the forward jaw portions 24,

25 upon a hook H therebetween. It will be understood that the jam nut 31 maybe tightened to prevent an accidental change-in the adjustment of the screw 36, and that further adjustment of this screw will b unnecessary during the use of the device, unless it is desired to clampfish' hooks H of a different size.

One advantage of this invention is that the fish ho k H e clamped .fiyn posi i n bya single motion-of. thehandle .38 and may be released by, a single movement of the handle in the reverse direction.

A further advantageis that the vise williirmly hold fish'hooks in a convenient position so that feathers, hackle, rand-other desired Ifly. material may be attached thereto, by cement, thread, or any othe d s red means- While there has. been disclosed in this specification one form in which the invention may be embodied, itisto be understood that this form isshown for the purpose of illustration only, and that the invention is not to be limited to the spe- Qific' disclosure, but may be modified and embodied in various'other forms without departing from its disclosed function. In Short, the invention includes all the modifications and embodi- 'men'ts coming 'within the scope of the following claim.

Having"thus"fully' described the invention,

what is claimed as new and for which it is d= sired to secure Letters Patent is:

In a fly-tying vise, a stationary jaw, a movable jaw pivoted thereto, and means for clamping a hook between the outer end portions of said jaws, said clamping means comprising an eccentric cam member rotatably mounted on the other end of onevof :said jaws andtan'zadjustable abutment comprising a ball bearingina tapped bore located in the other end of the other of said jaws, said cam member having a peripheral groove engaging said ball bearing, and said bore having a screw adjustably mounted therein to serve as a backing for saidball bearing." 7
