IMPROVEMENT IN RING-SPINNING FRAME.

TO ALL WHOM IT MAY CONCERN:

Be it known that I,-JOHN ASHWORTH, of North Andover, inthe county of Essex, and State of Massachusetts, have invented an Improvement in the Mode ofConstructing and Arranging Spinning-Rings in Ring-Spinners, so called; and I do hereby declare that the following is a lfull, clear, and exact description of the same, taken in connectionwith the accompanying drawings, making a part of this specification, in whichl Figure 1 is a plan of the'ring and a portion of the copping-rail, with a part in horizontal section, to show the screws which confine the ring thereto. Y A 4 Figure Zis a front elevation of the same, and

Figure 3 is a vertical section through the centre ofthe ring, and transverse to the rail.

The subject-matter of my invention relates to the method oi' attachingand adjusting the-rings of ringspinners, so called, so that the ring may be readily and accurately set concentric with the spindle.` In the construction ol' ring-spinning frames, when a long row of spindles is used, it isA-a matter ofgreat nicety and diiieulty to make all of the sockets for the rings in the eopping-rail accurately concentric with their respective spindles, and if so made at rst, they are liable to get out of adjustment by wear ofthe spindles or the springing of the rail, and therefore require some means of correcting the evil.

My invention consists in securing the ring to the rail by means of a clamping-screw and two set-screws, by the joint action of which the ring may be moved a short distance in any direction parallel to the plane of revolution of the spindle, by which means each ring may be brought to a position concentric with the spindle independently ofthe other. I

In the drawings, vA is the spinning-ring, made in the usual way, 'alle lower part of which is set in a circular socket in the copping-rail B, which is made somewhat larger than the exterior diameter of that 'part of the ring` which it encloses, and rests' upon the top ofthe rail by means of the shoulder C. Through the front sideof the rail, and opposite to the centre of the ring, is inserted a clamping-screw, D, the point of which screws into the ring, and the head of which rests upon the rail in a ceuntersink.

Upon either side ofthe screw D are insertedl twoset-serews, E E,\which screw into the rail, and the points of which bear against' the outside of the ring, as shown in fig. 1.

By means of the screw D, the ring is drawn toward the front side ofthe socket, and by the set-screws it is set `in the opposite direction, and by screwing `in one of the screws E, and withdrawing the other, the ring may be swung 'to the right or left,pivotingyupon the screw Din an obvious manner, and by'setting -up allot' the screws, the ring is held firmly in either position. v 4

The screws E are set in a higher place than the screw D, as seen in iig. 2, for the purpose of holding the opposite side of the ring down upon therail. This mode of attaching the ring to the rail may obviously be employed if' the ring is butpartially embraced'by the socket and operates in thesame manner.

I do not claim broadly the employment of means for adjusting a. spinning-ring in its rail, as that has heretofore been done in several ways; but

What'I do claimfand desire to secure by Letters Patent, iss The ring, secured to the rail, and adjustable tothe spindle by th'e clamping-screw and two set-screws, substantially as described. f v

Executed, May 22, 1868.

JOHN ASHWORTH.
