SHUTTLE-OPERATING MECHANISM FOR LQOiVIS.

rs'PECIFIGATION forming part of Letters Patent No. 445,682, dated February 3, 1891. Application filed July 2, 1890. Serial No. 357,480. (No model.)

To all whom it may concern.-

Beitknown that I, SAMUEL TURNER, a citizen of the United States, residing at NewBedford, in the county of Bristol and State of Massachusetts, haveinvented a new and useful Improvement in Shuttle-Operating Mechanism for Looms, of which the following is a specification.

My invention relates to that part of the mechanism of a loom which drives the shut tie, and has for its object to produce a mechanism for the same which will be more (lurable in its parts and less liable to get out of order, and by means of which the throw of the picker-stick is more easily and certainly adjusted.

To this end my invention consists in the combination of a picker-stick having a forked lower end with a base having a pivotal mo tion in the plane of the lay of the loom, to which base said fork is pivoted, whereby the upper end of the picker-stick is allowed free motion with the lay, a standard projecting upward from said base and alongside of the picker-stick, adapted to be adjustably connected with the sweep-bar of the loom, whereby a greater or less throw is given to the picker-stick, and means to retract the pickerstick to its normal position.

The accompanying drawings illustrate my invention, in which Figure 1 represents a front view of a portion of a loom supplied with my improvement. Fig. 2 represents a side view of the base to whichthe picker-stick is pivoted. Fig. 3 represents a plan view of the means whereby the base is pivoted to the loom. Fig. t represents a front view of a portion of a loom supplied with my improvement and showing the base to which the picker-stick is secured pivoted to the loom in a different manner than that shown in Fig. 1. Fig. 5 represents a side view of said base.

Similarletters refer to similar partsthroughout the several views.

(0 represents a portion of the frame of a loom.

Z) represents the lay.

0 represents the picker-stick, having bolted to it the arms (Z d, said arms being pivoted to the ears 3 3 on the base 1', whereby'the top of the picker-stick is allowed to have a reciprocating motion with the lay h.

f represents a standard rising from the base i and provided with the slot g, to which standard the sweep-bar n is pivoted bya wrist-pin g", which is adjustable up or down in the slot g, whereby a greater or less throw is given to the picker-stick.

In Fig. 1 the base 'i is pivoted to the projection p of the loom by means of the link Z, one end of which rests in a notch in the end of the projectionp and the other in the hook h of the base 2', which base is provided with a projection 7r, having notch in, which passes loosely through a mortise represented by the dotted lines .2 in the projection 12.

In Fig. at the based is represented as pivoted to the projection 9 by a bolt at w. The shaft 3, provided with the arms 25 and as, and the shaft o, provided with the cam a, by means of which. the required motion is imparted to the pickerstick, are the same as commonly used in ordinary looms. Vhen the cam it has operated on the arm 00 to give the requisite motion through the armt and sweep-bar n to the picker-stick c to throw the shuttle, the strap (1 and spiral spring 1' operate to cause the piekerstick to resume its normal position.

hat I claim, and desire to secure by Letter Patent, is

1. The combination of a picker-stick having a forked lower end with a base having a pivotal motion in the plane of the lay, to which base said fork is pivoted, whereby the upper end of the picker-stick is allowed free motion with the lay, a standard projecting upward from said base and alongside of the pickerstick,adapted to be adj ustablyconnected with the sweep-bar of the loom, whereby a greater or less throw is given to the picker-stick, and means to retract the pickerstick to its normal position, all as shown and described.

2. The combination of the picker-stick 0, provided with the arms (Z (Z, the base z, provided with standard f, having slot g, the ears y 1 to which the arms (Z (Z are pivoted, the hookh, and the projection 7.'-, having notch m, the projection 22, having mortise z, the link Z, the swcep-bar a, provided with wrist-pin adapted to be adjusted in the slot g, whereby a greater or less throw is given to the pickerbar 11, provided with wrist-pin adapted to be adjusted in the slot g, whereby a greater or less throw is given to the picker-stick, means for operating said sweep-bar, and means to retract the picker-stick to its normal position, 15 all as shown and described.

SAMUEL TURNER.
