New YORK, A CORPORATION or NEW YORK Application filed November 18, 1907. Serial No.l 402,627.

To all 'u-l om it may concern.'

. Be it known that I, LUKE F. GILLEsrlE, a citizen of the United States, residing at Newburgh,V in the county of Orange and Statewof New York, have invented an Im- )rove-ment in Picker-Stick Connections for ooms, of which the following is a speciication.

My invention relates to an improvement in picker-stick connections for looms. Heretofore the lug strap connecting the picker stick to the sweep-stick has ordinarily been made of leather, the relation of which was maintained to the ic-ker-stick by a loop of leather secured to roles made in said stick. The adjustn'ient of the lug strap was effected by other holesin the picker-stick and these holes weakened the picker-stick and the lug strap would stretch and wear.

The object of my invention is to increase 'the useful life of the picker-stick and to lend prominence to the other parts by the employment of a. lug strap of substantial character and means for adjustably Turing the position of the same upon the picker-stick without the necessity of perforating the said stick.

Incarrying out my invention, I provide a lug strap of metal of elongated U-form to straddle the picker-stick, a bunter Of leather or similar material in the bend of the strap securely held in place, and eyes in the other or free ends of the lug strap for a bolt for connecting the strap to the sweep-stick of the-loom.

The picker-stick is of usual character (wit-hout weakening holes) pivotally connected to a base of the loom and at its upper end provided with a icker to hit the shuttle and throw it across t 1e loom.

I provide means preferably in the form of adjusting clips secured to the picker stick both above and below the lug strap for positioningthe lug strap as desired and adjusting the same to regu ate the extent of movement or travel imparted to the said stick and so to control the force of the blow upon the shuttle. These cips are preferably made with curved parts for the eyes of the lugstrap to bear against.

In the drawing, Figure 1 is a side elevation and Fig. 2 an edge elevation representing the devices of my improvement and Fig. 3 is a sectional plan at the dotted line sc, I, of Fig. 1.

PICKER-STICK CONNECTION FOR LOO MS.

Patented Aug. 4, 1908.

The picker stick b is connected by a pivot shaft 2 to a cast base ay of the loom. vThe picker stick is preferably of wood and of usual character, and at the upper free end thereof a picker c also of usual character is secured to the stick against which the shuttle strikes at the end of its movement and by which with the further movement of the -stick b and in the bend thereof there is a buntcrof leather or oth'er suitable material connected in place by a bolt 4 which asses through the lug-stra and througi the bunter; the surface oi) the bunter bearing `against an edge of the pickerstick.

I provide means for positioning the lugst-rap and determining the relation thereof along the picker-stick and its distance from thc pivot shaft 2, and this means is preferably in the form of adjusting clips. These clips are made alike but reversed 1n position. Each clip comprises a yoke 7L of metal with free threaded ends on which there are nuts h* and a plate 'i notched and provided with forked or curved ends i. .The plate i presses against the back edge of the pickerstick while the. bent portion of the yoke passes around the frontv edge of the ickerstick and the threaded ends of the yo te. pass 9 through holes in the plate and the nuts clamp the parts togetherupon the picker-stick. The curved ends pass ove;` tie opposite faces of the picker-stick toward the cent-er and when these clips are arranged in oppo- 100 site ositions the said curved ends il come closey adjacent to the opposite top and bottom edges of the lug-strap Il; in fact the lug-strap d rests upon the. curved ends of the lower clip rocking thereon with the 105 swinging movement of the picker-stick and should the. yoke strap as tie result of the momentum of the parts tend to rise from its Support on the lower clip it will momentarily come in contact with the curved ends of the 11eA upper clip, its upper movement being arrested and it temporarily rocking on the y curved ends of the upper clip.

The greater the movement to be given to the picker-stick the nearer will the lug-strap be brought to the pivot shaft 2 because the -sweepstick e has a recognized .amount of movement and the smailer the extent of movement to be given the picker-stick t-he further away from the pivot shaft 2 is the. lug-strap placed. ln this way the extent of. movement desired is easily adjusted or regulated.

The )arts are strong, substantial, readily secure( and adjusted. Their use does not make it necessary to weaken the pickerstick by making holes therein, consequently the initial strength of the picker-stick is maintained and the parts being of `substantial character their useful life is very considerable.. i

I claim as my invention:

, 1. The combination with apicker-stick and a sweep-stick, of a metal lug-strap adapted to straddle the picker-stick, a'bolt connecting the lug-strap to the svreep-stick, a bunter and bolt for securing the same between parts of theA lug-strap and separate and independent adjustable means secured to the pic-ker", stick both above and below the lug-st-rap'for adj ustably locating t-he lug-strap and guiding the same.

2. The combination with a picker-stick and a sweep-stick, of a metal lug-strap adapted to straddle the picker-stick, a bolt connecting the lug-strap to the sweep-stick, a bunter and bolt for securing the same between parts of the lug-strap and spaced apart, separate and independent means secured to the picker-stick beth above and below the lug-strap for locating the lug-strap and guiding the same.

3. The combination with a metal base and a tapering wooden picker-stick and wooden sweep-stick, of a metal lugsirap of elongated U-form adapted to stradeile the picker-stick, a bolt connecting the lug-strap at its free ends to one end of the sweep-stick, a bunter of leather or similar material Within the bent portion of the lug-strap with the surfacev lug-strap and spaced apart, separate and independent means secured to the picker-stick both above and .below the lug-strap 'for loeating the lug-strap along tl1e"'picker-stick yand guiding the same.

4. The combination with a metal base and a tapering wooden sweep-stick, of a metal lug-strap of elongated U-form adapted to straddle the picker-stick, a bolt connecting the lug-strap at its free ends to one end of the sweep-stick, a bunter of leather or similar material within the bent portion of the lug-strap with the surface thereof 'coming against the edge of the picker-stick, abolt for securing the bunter to the lug-strap and means each comprising a. yoke straddling the picker-stick, a plate with holes engaged by the yoke and nuts for securing the parts together and curved ends to the said plateabove and below the lug-stra p for adjustably locating the lug-strap and guiding the same.

5. The combination with a metal base and a wooden sweep-stick, of a metal lug stra adapted tostraddle the picker-stick, a bo t connecting the lug strap to one. end of. the swee -stick, a bunter of leather or similar materia secured within the lug strap, with a'. surface thereof coming against the edge of the picker-stick and means each comprising a Yoke straddling the picker-stiek, a plate with holes engaged by the yoke, and nuts for securing the parts together, and curved ends to the said plate coming at either side of t-he picker-stick both above and below the lug strap for adjustably locating the lug strap and guiding the same.

Signed by me this lth day of November, 1907.
