Specification of Letters Patent. :Patefited O t. 19 1920 Application filed February 9,1920. "Serial No. 357,134.

To all whomit may concern:

Be it known that I, JEAN BAPTISTE DAUDE- LIN, a citizen of the United States, residing at Fall River, county of Bristol, State of Massachusetts, have invented certain new and useful Improvements in Shuttles, of which the following is a specification.

My present invention relates to hand threading shuttles and involves improvements in the ease and quickness of threading, protection against de-threading and especially certain features of tension by which the travel of the thread through the eye is controlled and ballooning prevented. As illustrative of my invention I have shown in the accompanying drawings an embodiment well adapted to manufacture. Throughout the specification and drawings like reference numerals are employed to indicate corresponding parts, and in the drawings:

Figure I is a plan view of a shuttle in accordance with my invention.

Fig. II a side view thereof.

Fig. III a plan view of the eye removed.

Fig. IV a side elevation of the same, and

Fig. V a sectional view on the line V-V, Fig. IV.

I have indicated at 1 a shuttle ofusual construction of bobbin chamber and throat, and having the usual threading passages 2 and 3. The bushing in the eye of the shuttle consists of a pair of generally cylindrical end members 4 and 5 connected by a central web 6. As shown in Fig. V the bushing is not quite cylindricbut rather helical so that the side slots 7 lie in slightly different planes, the forward edge "I being slightly above the rear edge 7 Across theouter end of the portion 5 is turned the bar 8 with the point 8 disposed for penetration into the wooden shuttle. Across the inner end of the portion 5 is a tongue 9 flattened below the level of 5 and constituting a tension bar under which the thread is run.

The tongue 9 is cut from the blank and bent down at the same time or after the blank is rolled. The portion 5 constitutes the real eye of the bushing, but the portion 4 assists in steadying and holding it as well as affording a clean passage through the eye.

Just behind the eye I run a transverse bar 10. This bar may be positioned rela tively to the eye so as to increase the tension of the thread. In the position shown in ig.,I, in full lines, it is placed close tothe eye and being'in a plane above the eye it gives a sharp turn to the thread and a considerable friction. In the position shown in dotted line 10 the bar would be farther back and the thread therefore run at a longer angle with less friction.

Various modifications in the several parts may obviously be made and the adjustment and relation of parts varied according to the nature of the work. All this may be done without departing from the spirit of the lnventio'n if within the limits of the appended claims.

\Vhat I therefore claim and desire to secure by Letters Patent is:

1. In a shuttle having a bobbin chamber,

an eye, and a threading passage leading from said chamber to said eye, the combinatlon with. a bushing in said eye having a tongue disposed transversely thereof and under which the filling runs from the bobbin chamber, of a bar disposed transversely across the throat of the shuttle to the rear 03f and slightly above the eye and over which the filling runs from the bobbin chamber, said tongue and bar constituting means for tensioning the filling.

2. In a shuttle having a bobbin chamber, an eye, and a threading passage leading from said chamber to said eye, the combination with a bushing in said eye having a tongue disposed transversely thereof and under which the filling runs from the bob- .bin chamber, of an adjustably mounted bar disposed transversely across the throat of the shuttle to the rear of and slightly above the eye and over which the filling runs from the bobbin chamber, said tongueand bar constituting means for tensioning the filling.

3. In a shuttle having a bobbin chamber, an eye, and a threading passage leading from said chamber to said eye, a tube in said eye having a transversely disposed attaching tongue at its outer end disposed for lodgment inthe shuttle and having a thread tensioning tongue at its inner end disposed substantially parallel to said attaching tongue. I

4:. A bushing for a shuttle of the class described consisting of a blank bent to provide a pair of tubular end sections, connected by an intermediate web, said sectlons being slotted along their under sides, a thread tensioning tongue bent down from said web and disposed transversely to the axis of the bushing and under which the thread runs, and an attaching tongue bent across the outer end of the bushing and over which the thread runs.

5. A bushing for a shuttle of the class described consisting of a blank bent to provide a pair of tubular end sections connected by an intermediate web, said sections being slotted along their under sides, a thread tensioning tongue bent down from said Web and disposed transversely to the axis of the bushing, and under which the thread runs, and an attaching tongue bent across the outer end of the bushing and over which the thread runs, the free end of said attaching tongue being turned inwardly and spaced from the bushing.

In testimony whereof I aflix my signature in presence of two witnesses.
