UNITED STATES PATENT @Fl lQE.

WILLIE G. EATON, OF NASI-IUA, NEW HAMPSHIRE, ASSIGNOR TO NASHUA IVIANUFAC- TUBING COMPANY, A CORPORATION OF NEW HAMPSHIRE.

SHUTTLE.

To all whom it may concern Be it known that I, WILLIE G. EATON, a citizen of the United States, residing at Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Shuttles, of which the following is a specification.

My invention relates to a device for detecting uneven yarn or filling; said device is particularly adapted to be combined with a loom shuttle.

The object of my invention is to provide a detecting device of the type referred to, particularly adapted to be combined with a loom shuttle in which a bobbin, having covered or reinforced yarn or filling thereon, that is filling having a central thread, and yarn spun or wound around the same is used, and my invention consists in certain novel features of construction of my detecting device, as will be hereinafter fully described.

In the use of reinforced or covered yarn or filling on a bobbin in a shuttle, as the yarn or filling is drawn out of the shuttle, as the shuttle passes back and forth through the shed in the operation of weaving, the covered or reinforced part of the yarn or 'lling is liable to break and become detachedfrom toe central thread, leaving only the central thread to be woven into the fabric, and making an imperfection in the fabric; and further in the spinning or Winding of the covered or reinforced yarn or filling on the bobbin to be used in the shuttle, an un covered portion of the yarn or filling, that is only the central thread, may be wound on the bobbin, causing, when the bobbin is used in the shuttle, an imperfection in the fabric.

By means of my improved device, particularly adapted to be combined with a shuttle, the uncovered or non-reinforced part of the yarn or filling, as the yarn or filling is drawn ed the bobbin in the operation of the loom, will be immediately detected, and through this detection, the operation of the loom will be immediately stopped to prevent the weaving of imperfect goods.

I have shown herein my device for detecting an uncovered section of the yarn or filling, used in connection with a loom shuttle, but it will be understood that I do not limit my invention to such use, as said detecting device may be used in connection with spin- Speoification of Letters Patent.

ning frames or winding machines, which handle covered or reinforced yarn or filling.

Referring to the drawing :-Figure 1 is a plan view of the self-threading end of a shuttle, and of the upper end of a bobbin in the shuttle, having reinforced or covered yarn or filling wound thereon, and my detecting device combined with the shuttle. Fig. 2 corresponds to Fig. l, but shows a portion of the covered or reinforced yarn or filling broken away, leaving only the central thread, which is caught and held by the detecting device. Fig. 3 shows, on an enlarged scale, a side view of the detecting device shown in Figs. 1 and 2, detached, and, Fig, 4 is a top or plan view, looking in the direction of arrow at, Fig. 3.

In the accompanying drawing, 1 is the loom shuttle, which may be of any ordinary construction, and has a self-threading derice 2 at the discharging end thereof.

3 is the upper end of a bobbin, and 4 is the covered or reinforced yarn or filling wound on the bobbin. The reinforced yarn or filling has a central thread i, which, in the process of spinning or winding the yarn or filling, is covered with additional yarn or filling, forming a covered or reinforced filling of ordinary construction, and used in weaving certain classes of fabrics.

My detecting device 5, shown in this instance combined with the shuttle, consists in this instance of a pin or stud, having in this instance a screw threaded end 5 to be screwed into an opening in this instance through the rear wall of the shuttle, and having the cylindrical shaped end 5, with an inclined slot or groove 5 therein; said slot or groove 5 extends in the path of the yarn or filling 4, as it is drawn off of the bobbin, and balloons or circles around the upper end of the bobbin, as the shuttle passes back and forth through the shed in the operation of weaving. The slot or cut 5 in the detecting device 5, is of such a width that it will not receive the full sized covered or renforced yarn or filling 4, but the same will slide over said slot or cut in the operation. of weaving, as shown in Fig. l; but the width of the slot or out 5" is such that if the central thread is denuded of its covering of reinforced yarn, for any reason, the central thread, in the operation of weaving, will pass into the slot or cut 5 in the detecting device 5 and be held by the same,

and prevent the further drawing oil of the yarn or filling from the bobbin, and consequently cause the breaking of the yarn or filling on the pick of the shuttle, and the operation of the filling fork mechanism to stop the loom, and prevent the weaving of an imperfect section in the fabric, all as will be readily understood by those skilled in the art.

It will be understood that the details of construction of my improved detecting de-' Having thus described my inventiomwhat I claim as new and desire to secure by Letters Patent is:

The combination with "a shuttle for han-,

dling a reinforced yarn or filling, of a detecting devicein one side of the discharging end of the shuttle, and at one side of the tip end of the cop or bobbin in the shuttle, said device having a slot or cut therein which will. notreceive the yarn or filling when it is in its normal condition, as it is unwound from the cop or bobbin, but will receive it in its abnormal condition, as it is unwound from the cop or lOObblIl, and pre vent the further unwinding of said yarn or filling from the cop or bobbin. ,7
