To all whom it may concern:

Be it known that we, WILLIAM H. PoR'r- NER and DANIEL H. BnAI'Rn, citizens of the 'Uhited States, residing at G d den, in the county of Etowah and State of Alabama, have invented certain new and useful Improvements in Loom-Shuttles, of which the following is a specification.

The present invention relates to loom shuttles, and the primary-object is to'pro- Yide a simple and effective guiding means for the'thread, which guiding means can be easily introduced and removed from the shuttle body, and when in place therein is rigidly positioned, and will permit the thread being readily introduced thereinto.

An embodiment of the invention that is at present considered the preferable one, is illustrated in the accompanying drawings, wherein Figure 1 is a plan View of the end portion of a bobbin, showing the thread-guiding means in place. Fig. 2 is} arsectional tiew on the line 2-2 of Fig. 1. Fig. 3*is a" persnective view of the thread guide detached. Fig. 1 is a detail sectional vie on the line H of Fig. 1. Fig. 5 is a sectional 'view on the line 5-5 of Fig. 1.

Similar reference numerals designate corresponding parts in all the 'figures of the' drawmgs.

Inthe embodiment illustrated, the shuttle includes the usual body '6, having a bobbin chamber 7 and a thread passageway including a longitudinally disposed portion 8 that opens into the front end of the bobbin chamber, and a transversely disposed po'rtioh 9 opening through one side of the body. The forward end of the portion 8 is tapered as illustrated at 10, in Fig. 2.

Located in the longitudinally disposed portion 8 of the thread passageway, is' a thread guide, which, in the embodiment shown, consists of a single piece of'sheet metal 11 bent-to form angularly disposed leaves 12 and 13. The leaf 12 extends across the passageway 8 at its juncture with the bobbin chamber 7, and is provided withra thread-receiving eye 14 having a throat 15" opening through the free edge of the leaf. The portionof this leaf above the throat 15, is curved, as shown at 16, so as to be spaced from the adjacent wall of the thread-passageway 8, in order to permit the thread being passed down into the throat l5, and

This leaf is also provided with a thread receiving eye 18*, from which extends a flared throat 19that opens through the front edge of the leaf. The upperv margin of' the leaf 13, at its front end, is curved .over and downwardly, as shown at 20, to provide a guard lip that overhangs the thread passage. The

thread guide is secured in place by a screw or other fastener 21, passed transversely through the front end of the bobbin body,

- through an opening22 in the leaf 13 andacross the passage8. This fastener prevents the detachment of the thread guide outwardly through the open side of the passageway 8, and by retaining the front end 17 in the slot 18, secures the same against any lateral play or movement.

It will be evident that this structure is exceedingly simple, and can be easilyin- "stalled'in a shuttle body. At the same time, it can be readily threaded, inasmuchla's the thread from the bobbin can be first passed .downwardly over the. curved edge 16 of the leaf12, and thence into the throat 15 of the eye 14. It can likewise be readil intro duced past the front end of the lea 13 into the throat 19, and thence to the eye 18%.

From the foregoing, itis thought thatthe construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. I

Having thusfully described our invention, what we claim as new, and, desire to secure by Letters Patent, is:

In a loom shuttle, a shuttle bodyqhaving a bobbin chamber and a passageway that extends from one end of the chamber and opens-through one side of the body, a thread guide located in the passageway and comprising angularly disposed leaves provided with thread-receiving eyes, one of said leaves extending across the vpassageway and the vother longitudinally therein, a guard liplocated at the upper and outer end of the latter leaf, the shuttle body having a 1011- In testimonywhereof we have afiixed'our giiudinaily disposed slot opening into the Signatures in presence of two Witnesses. bottom of the passageway and receiving the WILLIAM H.
