WEAVERS SHUTTLE.

SPECIFICATION forming part of Letters Patent N o. 718,806, dated January 20, 1903.

Annlication led March 20,1902.

To ctZ L11/"1.0711, it may concern.:

Be it known that I, LUDWIG WENGEFELD, a subject of the Emperor of Germany, residing at Vogelsmhle, nearDahlhauseu-on-the- Wupper, Rhenish Prussia, Germany, have invented new and useful Improvements in Weavers Shuttles, of which the following is a specification.

For well-known reasons the wooden shuttles employediu power-looms, more especially for weaving cloth, are provided with strips or plates of flat iron let into the sides of the shuttle and secured by means of countersunk wood-screws. Such shuttles, however, have many disadvantages, since the screws easily become loose or for some other reason project more or less above the surface of the plate-that is to say, of the shuttle. The consequence is that the dents of the slay or reed of the lay become injured, inasmuch as the dents are rendered uneven or injured by sharp-edged grooves being formed in them through friction, so that the reed gradually becomes totally useless. The leather of the cheeks of the shuttle-box is likewise rendered defective by the projecting heads of the screws, both on the front and back sides of the shuttle. Furthermore, the iron plate itself at the rear side of the shuttle exercises avery unfavorable action upon the dents of the reed, since by the continual sliding motion of the shuttle during its reciprocations in the ing or breaking the material of the thread.

The purpose of my invention is to overcome these defects by providing' a new method of securing the metal plates, the latter themselves, moreover, being of soft metal.

My new shuttleis illustrated in the annexed drawings, in which- Figure 1 is a plan view, Fig. 2 a front elevation, and Fig. 3 a rear elevation,of the shuttle. Fig. 4 is a cross-section taken on the line A B of Fig. 2. Fig. 5 is aplan view of a portion of one of the metal plates, drawn to a larger scale.

The metal plates a b, let into the frontand back sides of the shuttle, are provided at their inner surfaces with bolts or clips c, of copper or other flexible but tough metal and somewhat resembling split pins. These bolts Serial No. 99,170. (No model.)

may be conveniently secured to the inner surface of the plate by being soldered to it at their solid end. In letting the metal plate into the wood (the ends a or o of the plate being preferably turned somewhat inward for the purpose of affording a certain amount of hold) the bolts are pushed through corresponding holes provided in the walls of the shuttle and the two Shanks c' c of the split portion of the bolt c turned down upon the inside wall of the shuttle chamber or groove. In this manner the metal plate is tightly drawn upon, so that it lies closely against the wood at all parts. The ends c c should be somewhat further pressed down or let into the wood, so that the interior walls of the shuttle-chamber may be perfectly smooth and even, whereby injury to the cop on the tongue d or to the thread itself is impossible.

By the aid of the described method of securing the plates the sides o f the shuttle remain perfectly smooth, so that damage to the reed of the nature above described cannot 0ccur. Since the plate at the rear side can also be secured at the middle of the shuttle, where on account of the thinness of the wooden wall screws cannot be employed at all, warping of the shuttle is prevented.

A further important advantage of my new method of fastening is that the improved plates may be applied to old shuttles without any inconvenience in the manner described.

By manufacturing the plates of soft metal (tin, zinc, copper, &c., or of alloys of these metals) -all possibility of the rear side ofthe shuttle injuring the reed by friction during its sliding motion is obviated, the material of the plate being too soft to attack the dents of the reed. Rusting of the plate is thus also prevented-a matter of great advantage when weaving with moist or wet weft.

Although I have only shown one particular form of split pinon the drawings, it will be obvious that I may without departing from the essential feature of my invention use any other suitable form of split projecting member to hold the plates to the shuttle.

Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is

In a weavers shuttle, the combination with IOC) the shuttle-body provided With a groove in each side thereof and openings extending through the said grooved portions, of a plate having inwardly-turned ends and adapted to be mounted in the grooved portions of the shuttle-body, and pins integral with the inner face of said plate and provided with split ends, said split ends of the pins adapted to extend through the said openings and bent to engage the inner face of the shuttle-body ro for securing the plates in position.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

LUDWIG VENGEFELD.
