Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed Mayl23, 1916. Serial No. 99,297.

To all whom it may concern:

Be it known that I, ALFRED ROCK, a citizen of the United States, residing at lVilkinsonville, in the county of Worcester and State of Massachusetts, have invented cer tain new and useful Improvements in Loom Shuttle-Threading Eyes, of which the following is a specification.

My invention relates to loom shuttles, and particularly to the threading eye, combined with the delivery end of the shuttle.

The object of my invention is to provide an improved threading eye forloom shuttles, and my invention consists in certain novel features of constructionof my threading eye, as will be hereinafter fully described.

Referring to the drawing Figure 1 is a plan view of the threading end of a loom shuttle, with my threading eye combined therewith, and shown by broken lines; the tip end of the spindle, with a bobbin thereon is shown in the shuttle.

Fig. 2 is a side view of the end of the shuttle shown in Fig. 1, looking in the direction of arrow a, same figure.

Fig. 3 is a section, on line 3, 3, Fig. 2, looking in the direction of arrow Z), same figure.

Fig. 4 is a section, on line 4, 4, Fig. 1, looking in the direction of arrow 0, same figure.

Fig. 5 is a plan view of my improved threading eye.

Fig. 6 is a rear side view of the threading eye shown in Fig. 5, looking in the direction of arrow 0?, same figure.

Fig. 7 is an end view of the threading eye shown in Fig. 5, looking in the direction of arrow 6, same figure, and,

Fig. 8 is a section, on line 8, 8, Fig. 6, looking in the direction of arrow f, same figure.

In the accompanying drawing, 1 is the threading end of the shuttle body, of any ordinary type, and having a central longitudinal recess 2 therein for the spindle 3,-

and the bobbin 4 on the spindle, with the thread 4 leading off from the bobbin. 5 is the thread recess, of circular shape. 6 is a vertically extending slit in the upper side of the shuttle, leading from the thread recess 5 and extending to and leading into the horizontal slot 7 in the front side of the shuttle, see Fig. 2.

Extending transversely through the shut tle, just beyond and connected with the thread recess 5, is an opening 8 for the threading eye.

All of the above mentioned parts may be of'the usual and well known construction in loom shuttles.

I will now describe my threading eye, which is combined with the transverse opening through the shuttle.

The threading eye 9, shown detached in Figs. 5, and 6, is of non-circular shape in cross section, preferably square, with its discharging end preferably slightly tapered and rounded. The threading eye 9 is made in this instance solid at one end, and has a central longitudinal or axial opening 9 in its other end. An opening 9, preferably of circular shape, leads into said opening 9 from the top' side of the threading eye. A slit 9 extends in a diagonal direction through the rear side of the threading eye, see Fig. 4, and connects the opening the central longitudinal opening 9, said slit communicating with or leading into both of said openings so as to allow the thread, in the threading of the shuttle, to pass through said slit 9 and into the opening 9, and into the central opening 9, and out through the discharging end of said last-named opening, as shown in Figs. 1, 2, and 3.

The threading eye 9 is combined with the shuttle body, by inserting the slightly tapered end thereof, with the opening 9 on the upper side of the threading eye, into the transverse opening 8 through the shuttle body and which opening is preferably of circular shape, and driving or otherwise forcing the threading eye into said opening 8 in the shuttle body, from the end of said opening 8 at the top of Fig. 3, until the opening 9 in the threading eye is opposite the thread recess 5 and is in alinement with the inner end of the vertically extending slit 6 in the shuttle body, as shown in Fig. 3. The longitudinal opening 9' in the threading eye preferably extends from the thread exit or discharge end of said eye inward part way through said eye or to the top opening 9, thus leaving the other end of the body of said eye solid so that it will withstand the driving impact necessary in forcing said non-circular or square eye into the round transverse opening 8 in the shuttle body in which it will be held so tightly that it cannot become loosened.

9 with- The loose end 4' of the thread on the bobbin 4 is then drawn across the thread recess 5 in the shuttle body (which recess eX-' tends down to the transverse opening 8) and into the vertical and horizontal slits 6 and 7 in the shuttle body, and passes into the diagonal slit 9 in the threading eye 9, and through said diagonal slit into the top opening 9, and the central opening 9, and out of the discharging end of the threading eye, in the usual and well known way, and as shown in Figs. 1,2 and 3 of the drawings. This threading operation is possible owing to the fact that the horizontal slit 7, which communicates with the vertical slit 6, is in the horizontal plane of the opening 8 and the threading eye 9 therein.

The advantages of my improved construction of a threading eye for loom shuttles,

will be readily appreciated by those skilled in the art.

The threading eye may be made from a block of solid metal, of non-circular shape, and preferably square, in cross section, and the openings 9, and 9 therein bored out, and the diagonal slot 9' preferably sawed out, to make the complete threading eye; the discharging end is preferably rounded. If preferred the threading eye may be pressed out of steel, or other metal.

The expense of making my threading eye is much less than the expense of making the ordinary threading eye.

My improved threading eye, having a solid holding part of rectangular or square form in cross section, will be rigidly held in the transverse opening through the shuttle body, which may be of the usual circular shape, and it will be prevented from turning,or working loose therein, all as will be readily understood by those skilled in the art.

It will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with a loom shuttle having a transverse opening, of a threading eye fixed tightly in said opening and comprising a solid holding part which is rectangular in cross section, and a tubular part having top and axial openings and having also a diagonal slit communicating with said top and axial openings.

2. The combination with a loom shuttle having a transverse opening, of a threading eye fixed tightly in said opening and comprising a solid holding part which is square in cross section, and a tubular part having top and axial openings and having also a diagonal slit communicating with said top and axial openings.
