' 5 Claims. (Cl. 139-212) UNITED STATES PATENT OFFICE This invention relates to loom shuttles and has particular reference to the provision of means in the eye of the shuttle whereby the yarn or thread or weft being drawn from the shuttle at each pick in each direction,in the course of weaving a fabric, is caused at irregular intervals to have a rufiied or fluffy or bunched effect in spots and accordingly the material or fabric being woven will be given a very different appearance than that of the fabric woven by the use of a shuttle not provided with the present invention.

The present invention consists broadly in roughening the side walls of the shuttle eye, or in applying to the walls of the eye, some hardened, roughened material such as emery, cement or the like, whereby when the yarn or thread is drawn through the eye, in the process of weaving, the same will be ruliled or fiuifed in spots and accordingly such rulfled or fluffed spots will appear in the finished fabric.

In the present invention an abrasive material such as emery, or cement of some character, is positioned around the sides of the delivery eye of the shuttle in position to be engaged by the filling thread as it emerges from the eye. The construction and arrangement of the abrasive is such that the short, loose fibers which are spun on the filling adhere or catch on the ab- W rasive material and are caused to gather into a bunch or slub or fluff, along the thread. When such a slub or bunch is formed and has reached a certain appreciable size it pulls loose' from the abrasive or roughened formation on the walls of the eye and amather slub is immediately started and eventually formed and as in the first instance pulls away from the material, and this continues until the filling on the bobbin is exhausted.

One form of embodiment of the present invention is shown in the accompanying drawing, wherein corresponding reference numerals are used to indicate corresponding parts in each of the views.

In the drawing:-

Fig. 1 is a top plan of the delivery end of the shuttle, including a portion of the bobbin car-' rying the filling thread, the portion of the shuttle about the eye being broken away and shown in section; and

Fig. 2 is a front-elevation.

In the drawing l indicates the shuttle having the usual bobbin ll carrying the thread I! which passes over the tension pad I3 under the cover 56 I4 and shield l5 through the eye IS, in the usual mariner in the operation or pick of the shuttle across the loom.

In the present invention I have roughened in any desired manner the side walls I! of the eye or outlet I6, preferably by coating or lining said walls with an abrasive roughened material l8. The filling thread I2 in its passage through the eye l6 contacts and passes over the roughened abrasive material on the left hand wall of the eye in the movement of the shuttle to the right 10 and over the abrasive material on the right hand wall in the passage of'theshuttle to the left.

As the thread passes over this roughened portion of the eye in the process of weaving there will be formed on the thread at intervals small fiuffs or bunches of the thread as at IS. The thread passing over the abrasive material is caused to fluff or bunch at intervals and when a certain amount or size of fiuff is formed the same then pulls away from the abrasive material and passes on out of the eye and the formation of another fiufi or bunch is begun.

It will thus be seen that as this thread with the fluffs or bunches thereon is woven into the fabric quite a difference in appearance will be given to the fabric from that wherein the filling thread is not so acted upon.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1.,A loom shuttle, a bobbin therein carrying yarn having loose fibres or nubs spun thereon, said shuttle having an eye or outlet through which the yarn passes, the walls of said eye being lined with an abrasive material over which the yarn passes, whereby in'the operation of weaving said nubs or loose fibres are formed into fiulfs or bunches at'intervals on the yarnl 2. A loom shuttle, a bobbin therein carrying yarn having loose fibres or nubs spun thereon, 4 said shuttle having an eye or outlet through which the' yarn passes, an abrasive material in said eye over which the yarn passes, whereby in the operation of weaving said nubs or loose fibres are formed into fiuffs or bunches at intervals on the yarn.

3. A loom shuttle, a bobbin therein carrying yarn having loose fibres or nubs spun thereon, said shuttle having an eye or outlet through which the yarn passes, the opposite walls of said eye being coated with an abrasive material over which the yarn passes, whereby in the operation of weaving said nubs or loose fibres are formed into fiufis or bunches at intervals on the yarn.

4 A loom shuttle, a 'bobbin therein carrying ing yarn having loose fibres or nubs spun thereon, said shuttle having an eye or outlet through which the yarn passes, the opposite walls of said eye being coated with emery over which the yarn passes, whereby in the operation of weaving said nubs or loose fibres are formed into fiufis or bunches at intervals on the yarn.
