PlCKER-STICK MOTION FOR LOOiVlS.

SPECIFICATION forming part of Letters Patent No. 638,203, dated November 28, 1899. Application filed August 2, 1899. $erial No. 725,854. (No model.)

To all whom it may concern.-

Be it known that I, DAVID B. SYME, of New Bedford, county of Bristol, Commonwealth of Massachusetts, have invented an Improvement in Picker-Stick Motions for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figure on the drawings representing like parts.

This invention has for its object the production of means for varying the inclination of the picker-stick of a loom at the time the blow of the shuttle is received to thereby regulate the checking of the shuttle.

When the impact of the shuttle and stick is delayed, by inclining the stick outward the checking effect upon the shuttle will be less than when the stick is moved inward, so that impact will take place sooner.

Figure 1 is a partial side elevation of a sufficient portion of a picker-stick and its support to be understood with my invention applied thereto. Fig.2 is a similar view of the picker-stick shoe detached, and Fig. 3 is a perspective view of the toe detached.

Referring to Fig. 1, the picker-stick P, of

usual construction, is attached at its lower end to a shoe A, Fig. 2, by a suitable bolt 5, Fig. 1, the shoe having a curved sole a, which rests upon and rocks on the usual support or stand B, the latter having a slot or opening b through which extends a hooked lug a, projecting from the bottom of the shoe. A spring S, of usual construction, is attached at its free end by a strap 3 to said lug and acts to return the picker-stick and shoe to normal full-line position, Fig. 1, the picker-stick being actuated by usual means. (Not shown.)

It will be seen that the convex sole of the shoe does not extend beyond the bottom of the picker-stick, but meets the flat face 0 of a toe 0, (shown separately in Fig. 3,) the toe having an upturned ear c,which rests against an upturned rearward extension or web a formingapart of the shoe, the latter having a downturned transverse hook a which receives a transverse upturned lug c at the inner end of the toe.

A bolt 12, extended through a hole a in the web of the shoe, passes through a slot 0 in the ear 0 and receives a clamping-nut 15, Fig.

1, the slot permitting adjustment of the toe on the shoe.

Referring to Fig. 1, it will be seen that if the bolt is moved toward the upper end of the slot c the picker-stick will be swung to the right or inward toward the center of the breastbeam, meeting the shuttle sooner than it will in the full-line position shown, and the checking effect on the shuttle will be greater. By moving the bolt nearer the lower end of the slotthe picker-stick will be moved more to the left or outwardly and checking will be decreased, so that the checking may be regulated by varying the inclination of the picker-stick when it meets the shuttle.

The dotted lines, Fig. 1, show the position assumed by the parts when the picker-stick is moved outward by the shuttle blow, the outer end of the toe acting as the fulcrum as soon as the parts move from full-line position.

A prong 0 depending from the plane face of the toe at its outer end, passes through an opening 19 in the support, B and positions the toe,'preventing lateral movement thereof.

The adjustment of the picker-stick is thus readily and quickly effected and the checking action on the shuttle varied as desired.

Having described my invention, what I claim, and desire to secure by Letters Patent,- 1s- 1. In a device of the class described, a picker-stick, a shoe having a curved sole, a support upon which it rocks, and a toe adj ustably connected with the shoe and having a flattened face to rest upon the support.

2. In a device of the class described, a picker-stick,a shoe having a curved sole, an upward rearward extension and a hook, and a support upon which the shoe rocks, combined with a toe having a fiat bearing-face, an upturned lug to enter the hook in the shoe, and means to adj ustably connect the shoe and its toe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DAVID B. SYME.
