LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 708,592, dated September 9, 1902.

Application led December 19. 1901. Serial No. 86,472. (No model.)

To all whom t may con/cern:

Be it known that I, ADOLF SCI-IAUB, a citizen of Switzerland, residing at No. 192 Burhaus avenue, city of Paterson, county of Passaic, State of New Jersey, have invented certain new and useful Improvements in Loom-Shuttles, of which the following is a specification.

My invention relates more particularly to loom-shuttles such as are employed in narrow-fabric looms, and my main object is to enable a bobbin of increased capacity to be satisfactorily employed in connection therewith. Heretofore the capacity of the bobbin has been objectionably limited bythe necessity for providinga satisfactory angle of pull upon the bobbin in `un'winding the thread from the portions of the latter farthest lfrom the shuttle-eye, this angle becoming objectionably acute unless the bobbin is made comparatively short, because ofthe limited height of shuttle which it is practicable to use in connection with cooperating parts of the loom mechanism.

My invention consists in providing a`shuttle having improved thread-guiding means between the bobbin and the shuttle eye, whereby a bobbin of increased length and capacity may be employed in connection with the same or even decreased height of bow.`

It is fully described in connection with the accompanying drawings, and its novel Vfeatures are particularly pointed out in the claims.

Figure l is an elevation of a shuttle embodying my invention in preferred form, the thread from the bobbin being shown passing through the several guides to the outlet-eye, but without any tension thereon. Fig. 2 is a similar view to Fig. l, but showing the thread under tension. Fig. 3 is a plan View showing a portion of the bow cut away to more'clearly reveal the preferred manner of supporting the supplemental central guideeye.

A represents the shuttle, and B the bobbin rotatably mounted therein, as usual, and differing from the ordinary construction in being considerably longer, and consequently holding an increased quantity of thread.

The shuttle is of suiicient length to receive this elongated bobbin,while the height or bow of the shuttle instead of being increased, as would be necessary without my improvements to prevent the thread from running o at objectionably acute angles, may be actually as well as relatively reduced. Inasmuch as this height or bow of the shuttle is practically limited, as already stated, owing to the construction and operation of the loom, the length of the bobbin has heretofore been correspondingly limited.

In order to permit of increasing the length of the bobbin relative to the height of the shuttle and at the same time provide for running o the thread at easy angles from all points inthe length of the bobbin, I employ, in connection with the usual central drawingoff eye 2 in the bow, a slot or guideway 3, eX- tending lengthwise of the bow, through which the thread from the bobbin passes on its passage indirectly to said eye 2. I also provide the shuttle with a supplemental guide-eye 4, located in the bobbin recess or opening below the central bow-eye 2 and about midway of the length of the bobbin. This eye 4 may be carried by the shuttle in any suitable manner, though Ipreferablysupportit yieldingly by means of suspension-cords 5` 5, running parallel with the bobbin, as shown.

In addition to the features already referred to I preferably employ theintermediate right and left tension-eyes Gand 7, which are commonly used, the attaching- springs 8 and 9 of which permit said eyes to be moved toward each other as determined by the tension of the thread. In threading up the shuttle the thread is first run off from the bobbin through the slot or guideway 3, then down to the supplemental guide-eye 4, thence successively through the right and left tension-eyes 6 and 7, and finally through the central bow-eye, as usual. In operation the angle formed by the thread in running off from the bobbin is very easy; in fact, it is only about one-half as acute to the axis of the bobbin 'as it would be if run direct to the eye 2, as will be seen in Fig. 2, this being due to the fact that the guideway 3, through which it iirst passes, extends nearly the full length of the bobbin and to its indirect passage from said guideway, through the supplemental central eye 4L to the outlet-eye 2. The advantages resulting from thus increasing the length and resulting capacity of the shuttle, while at the same time maintaining its low height and even improving the running off of the thread, will be readily understood. I do not desire to limit myself to the preferred construction shown and described; but

What I claim isl. A loom-shuttle having its bow formed with a longitudinal slot directly therein and provided with a central drawing-oft eye, and an intermediate guiding means for the thread on its passage from said slot to said eye.

2. A loom-shuttle having a single bobbinchamber, a bow formed with a continuous longitudinal slot directly therein and pro' vided with a central drawing-off eye, and an intermediate guide-eye located approximately midway the length of the bobbin and between the latter and the drawing-off eye.

3. A loom-shuttle having its bow formed with a longitudinal slot constituting a guideway for the thread directly in said bow and said bow provided with a central drawing-0E eye, a guide-eye located approximately midway the length of the bobbin and between the latter and the drawing-off eye, and inter mediate right and left tension-eyes.

4:. A loom-shuttle having a central eye in the bow, a longitudinal guideway to receive the thread on its passage from the bobbin to said bow-eye, and a guide-eye yieldingly supported midway of the length of the bobbin and below the bow-eye.

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