SPINNING.

SPECIFICATION forming part of Letters Patent No. 700,272, dated May 20, 1902.

Application filed April 19, 1901. Serial No. 56,605. (No model.) 1;

To (LZZ whmn it may cancer-m Be it known that I, JACOB XVIDMER, a citizen of the United States, and a resident o'f New Hartford, in the countyof Litchfield'and-State of Connecticut,have invented certain new and useful Improvements in Spinning, of which the following is a 'full, clear, and exact description, whereby any one skilled in the art' can make and use the same.

My invention relates to the art of spinning fibers of various material into the form of a thread, and more particularly to the guide or tension device by the use of which the fibers are twisted and then wound upon a bobbin, as exemplified in the ordinary form of ringspinners.

The object of m'yinvention is to produce a guide by means of which improvedresults'in the mechanism of spinning, in-the art, and in the resulting thread are obtained as compared with the prior art. I

Referring to the drawingswhioh'form part hereof, Figure 1 is a View in elevation of a spindle, bobbin, and part of a spinning-frame. Fig. 2 is a plan-view of one form of embodiment of my invention, the guide-supporting ring being cut awayin' part and the spindle and bobbin shown in section. in central section of the guide and its supporting-ring. V

In the accompanyingdrawings only so much of the mechanism of a spinning-frame'is shown as is required to illustrate the relative location and manner of operation of one form of embodiment of my invention, and in these drawings the letter a denotes a spinningspindle mounted in a spindle-rail b of any ordinary formof spinning-frame, the spindle being driven by a band a from any suitable drum or pulley in the usual manner. 7

A ring 01 is mounted in a ring-rail e and serves as a frame to locate the guide f and to support it when in a position of rest, the guide being located in a groove d;'-for.med in the The ring-is located, in an opening-in the ring-rail, and'the-spininner surface of the-ring.

Fig. 3 is a view.

practically suspended on thethread h, which i extends downward to the"guide"(see Fig. 1) and passes through the eye in the guide-arm f and the eye in the guide-arm f before winding upon the bobbin. This arrangement balances the guide, as well as suspending it, so that in winding no other support for the guide is required, and there is practically no rubbing contact of the guide with the walls of the groove in the ring d.

By the term groove any form of recess in the ring at or within guiding-walls is desig nated. v

Owing to the fact that ring-spinners as now extensively used are fitted to support a ring in the ring-rail, the form of ring with its guideholding socket as shown is preferred to en-' able my invention to be easily and cheaply adapted in a practical form to existing frames and methods of operation, but is by no means limited thereto.

It is preferred that at least one of the guidearms, as f shall be made long enough to bemass builds-upon it, and this is agreat advan-;

tage over the old formofring-traveler guide in common use. Ih-thelatter the,tension is almost to the breaking point of the yarn when the thread first winds upon the bobbin, owing to the angle of the draft and the resistance of the traveler to motion along the ring which supports it, and this tension grows less as the angle increases by the building up of the thread mass on the bobbin, resulting in a variation in strength of the thread along its length. Another advantage from the use of my new guide is that thread of the same material and size and with spindles running at the same speed is wound upon bobbins of same size to an amount almost twice as great for the same diameters as compared with a thread mass wound on the same bobbin by the old devices--that is, the thread is wound more compactly by the use of my device. Another advantage is that there is an increase in tensile strength in the thread wou-nd by the use of my new guide as compared with the old, actual tests showing a gain of from twenty-five to thirty-two per cent. Owing to the fact that the greater length of thread is wound by the use of my new guide, the bobbins need not be (lofted as often, and in this regard a saving in time of nearly fifty per cent. has been shown, only thirty minutes per day in place of one hour being required. A still further advantage is found in the cheapness of construction of the new guide and its support as compared with the ring and its traveler. These advantages and several others How from the .use of my new guide, which is balanced and practically independent of any support in use other than the thread which is wound by its use, and it may be termed a suspended guide to distinguish it from those of the prior art, which require a positive support and guide distinct from the thread-as, for instance, the flanged ring for the well-known traveler mounted on it.

My invention is capable of various modifications and changes from the form herein shown without the exercise of more than the accumulated skill of the art, and such variations are within the scope of my invention as herein disclosed and claimed.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. An improved thread-guide for a spinning-machine comprising an annular body part and two arms, on the body part of the guide, located substantially opposite to each other on said body part. 2. In combination in a ring-spinner, a ring supported in operative relation to a spindle and having a groove in its inner surface, and a thread-guide located in said groove with a plural number of arms located opposite to each other and projecting from the body part of the guide and with eyes or loops for the passage of the thread. A

3. An improved thread-guide for a spinuing-machine comprising an annular body part and a plural number of arms projecting on opposite sides thereof,one arm being longer than the other on the opposite side of the body part, and eyes or loops formed in the arms for the passage of a thread.
