SULLIVAN, of a ring-spinning machine provided with my of New Bedford, in the county of Bristol and improvement, the central portion being' cut State of Massachusetts, have invented a new out to reduce the length of the drawing.

The curtain l forms a flexible yielding surface along the rear of uthe row of spindles and sufficiently close to the same to prevent the excessive ballooning of the yarn and the interference of the yarn of adjacent spindles.

In practice I iind that it requires one or more turns of a spindle, even at the highest speed, to exert sufficient centrifugal force on the yarn to cause it to bow outward or balloon perceptibly and that the yarn by coming in contact for a considerable length at each revolution with the surface of the curtain 15 does not acquire sufficient centrifugal force to bow outward or balloon so as to come in contact with the yarn of the adjacent spindle. I further find that the spindles may be placed closer together than is now customary without the yarns of the adjacent spindles interfering with each other even at a higher speed than is now generally used.

Consequently the number of spindles in a ma chine may be increased as well as the speed and a corresponding increase in the production secured.

It is also obvious that the curtain 15, whether fixed or rolling, prevents oats from being carried in between the spindles from the front and limits the ballooning of the yarn.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a ring-spinning machine, the combination with the spindles, the reciprocating rin g-rail, of a curtain secured to the rin g-rail, and a self-windin g curtain-roll supporting the upper part of the curtain and located in a plane above the ring-rail, whereby the yarn is protected against floats and excessive ballooning, as described.

2. In a ring-spinning machine, the combination with the front beam and the ring-rail of the machine, of the roller 16 supportedin suitable bearings above the highest reciprocation of the ringrail, a curtain secured to the roller as described, for automatically rolling up and letting out the curtain, whereby the space between the ring-rail and the front beam is closed by the curtain.

3. In a ring-spinning machine, the combination with the spindles, the reciprocating ring-rail and the front beam of the roller 16, the cord 18, the weight 19 and the curtain 15 secured to the roller and to the ring-rail, whereby the curtain is automatically adjusted to close the space between the ring-rail and the front beam, as described.

In witness whereof I have hereunto set my hand.
