LOOM SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 372,239, dated October 25,1887.

Application filed April 27, 1831. Serial No. 236,360. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES GUSTAV ROOT, of San Quentin, Marin county, State of California, have inventedan Improvement in Loom- 5 Shuttles; and I hereby declare the following to befia full, clear, adamant description o fthe same.

My invention relates to shuttles such as are employed to carry the bobbins in weaving fabric; and it consists in the combinatiomwith a shuttle-body, of the improved tip and fastening-bolt hereinafter described.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a side view of one end of the shuttle, showing the tip in place. Fig. 2 is a plan view thereof; and Fig. 3 is a sectional viewof the cap removed, showing the bolt bywhich it is secured.

In the manufacture of loom-shuttles it is customary to protect theend of the shuttlebody by means of a flat plate which is variously secured to the shuttle-body and has a spur or point projecting from one side there-- of, Which serves to insure the passage of the shuttle properly between the threads of the warp, while a portion of the fiat plate serves to receive the impulse of the picker which throws the shuttle from end to end of its travel. These plates are sometimes secured to the end of the shuttle'by means of two pins which project from the plate and are driven into the end of the shuttle, or they may be secured by means of screws, one of which has its head countersunk to fit flush with the surface of the plate, while the other is provided with a pointed extension, as before described. I11 either case the rapid movement of the shuttle and the violent blows to which it is subjected cause the wood to become split in a short time, or the plates to be loosened, and, furthermore, the shuttle-bodies are very often split and broken in the act of putting the plates on. In my invention, A is a metallic cap, made of 5 sufficient length to have a chamber, B, formed within itsIarger end ofthe same shape as the end of the shuttle to which it is to be fitted.

O is the pointed tip which insures the proper passage of the shuttle between the threads, as before described. A countersunk hole, D, is made through the centmlportion ofrtliew llcr-r tallic tip, and a bolt, E, passes through this hole and a corresponding one in the end of the shuttle, so that it enters the central open space within the body of the shuttle. A nut, F, is

screwed upon the threaded end of this bolt,

her adapted to receive the end of the shuttlebody, a bolt passing through said chamber and the end ofthe shuttle-body,havingahead countersunk in the outer end or wall of the tip,and a securingnut on the inner end of said bolt, substantially as herein described. 2. The combinatiomwith a shuttle-body, of a metallic cap having a pointed tip, 0, and a chamber by which said cap is fitted to the end of the sh uttle-body, and a bolt passing through said cap and the end of the shuttle-body, hav- 8o ing at one end a head countersunk in said cap and at the opposite end a securing-nut, substantially as described.

ln witness whereof I have hereunto set my hand.

CHARLES GUSTAV ROOT.
