LOOM-SHUTTLE.

and State of Massachusetts, have invented.

a certain new and useful Improvement in Loom-Shuttles, of which the following is a specification.

The present invention consists in an improvement in connection with the weft-carrier holding-spring of shuttles used in automatic weft-replenishing looms wherein the replenishment of weft is effected by discharging the spent weft-carrier from the shuttle and substituting a fresh one therefor.

This application is a division of'application filed December 3, 1909, Serial No. 531,172.

" The improvement is illustrated in the accompanying drawings, wherein:

Figure 1, is a plan view of one end of a shuttle equipped with the improvement. Fig. 2, is a vertical section in the plane indicated by the line 22 in Fig. I. Fig. 3, is a cross-section in the plane indicated by the line 33 in Fig. 2. Fig. 4:, is a perspective view of the weft;carrier guide, a portion being broken away.

A, is the body. of the shuttle which at one end is furnished with a shuttle spring, having two separated elastic jaws, B, B, Which serve to grasp and yieldingly hold the buttend of a weft-carrier, as is common in loom shuttles for automatic weft-replenishing looms. The illustrated shuttle spring with its two jaws and its intervening shank is made of a single piece of sheet steel, bent into shape, as set forth in application for Letters Patent of the United States filed by me October 15, 1909, Serial No. 522,814. As in that application, the single piece shuttle spring has its double wall shank located and fitting Within a recess of the shut-' tle chamber and is secured to the shuttle by means of a bolt C, extending through holes in the two separated walls D, D, of the shank, as shown in Fig. 3. This bolt at its screw-threaded end engages a retaining nut E, all as usual.

On account of the yielding character of the shuttle body alongside 'the recess in which the shuttle spring shank fits, the pres sure, employed in tightening the bolt C, in its nut E, frequently causes the shuttle walls to approach each other, thereby forcing the Specification of Lettersi 'atent.

Patented 13120.23, '1 913.

this application filed June 24,

two walls of the shuttle spring shank slightly toward each other, with the result thatthe free ends or jaws 15, B, of the shuttle spring may be brought so close to each other that the space between them is not sufficiently adequate to readily receive the butt of an incoming weft-carrier. This may result in occasional breakage 01', at least, in failure to properly receive the incoming weft-carriers in every instance. 7

The present improvement consists in the means employed for preventing any collapsing or yielding of the walls of the shuttle spring shank due to the pressure of the retaining bolt C. In connection with the shuttle spring there is employed the usual directing guide F, for directing the butt of an incoming weft-carrier into proper position between the jaws of the shuttle spring, and it is shown, as in the aforesaid application, with an upper arm G, having a hole a, for the reception of the screw H, which holds the guide in place in the shuttle. This to arm G, of the weft-carrier guide is formed with a down bent spacing tongue I, which is made by partially cutting or stamping a hole Z), in the said arm (see Fig. 4t) and bending down the spacing tongue. This spacing tongue is just wide enough to enter between the two walls, D, D, of the shank of the shuttle spring and to closely lit the space between said walls, as shown in Fig. 3. Accordingly, this spacing tongue extending into and fitting the space between the walls of the shuttle spring, shank, prevents any forcing of said walls toward each other as the result of the compressive action of the holding bolt C.

I claim-- 1. A loom shuttle having, in combination, a weft-carrier holding spring composed of a single piece of steel bent into shape with a double wall shank for connection withihe shuttle; a retaining bolt passing through the body of the shuttle and through holes in the two walls of the said shank: and a welt carrier guide ha ring a securing lop arm crtending above the shuttle spring: shank, said top arm having an integral down turned tongue extcndin; into and filling the space between the two walls of lhc shuttle spring shank.

2. A loom shuttle having. in combination, a weft-carrier holding s,fu'in w ilh a double tongue extending into and fitting the space between the two walls of the shuttle spring shank.

3. A loom shuttle having, in combination, a Weft-carrier holding springv with a double Wall shank for connection withthe shuttle;

a retaining bolt passing through the body of the shu tle and: through hoie in the two Walls 0 the said shank; and a weft-carrier guide having a tongue extending into and fitting the space between the two Walls of the shuttle spring shank.

In Witness whereof, I have hereunto signed.my namein the presence of two-sub;
