ATTACHMENT FOR WOOL-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 653,836, dated July 17, 1900.

Application filed October 10, 1899. Serial No. 733,126. (N model-l T0 (tZZ whom it may concern.-

Be it known that I, AMARIAH AVERY, a citizen of the United States, residing at Man'- chester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Attachments for VVool-Spinning Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates more especially to wool-spinning, but it is equally as well adapted to cotton-spinning, the objects being to wind more yarn or thread on a bobbin, to twist the fibers of the yarn more uniformly than can be done by the use of the ordinary caps used in spinning wool, to obtain a more even tension, thus making the yarn more even and smooth, and, finally, to lessen the vibration of the spindles. The frequent stopping to doff consumes much time which by the use of my improvements is saved, the bobbins being wound very evenly and much more tightly, thereby increasing the quantity of yarn on a bobbin between three and four hundred per cent. over that which can be wound upon the same when the cap is used. The invention consists in the construction which will be fully set forth in the following specification and claims and clearly illustrated in the drawings accompanying and forming a part of the same, of which- Figure 1 is a broken elevation showing a portion of a wool-spinning frame, several spindles and bobbins thereon, and my improved stationary ring-rail and its rings in proper relation thereto. Fig. 2 is a plan view of the same parts. Fig. 3 is an enlarged detail plan view showing a portion of the stationary ring-rail and showing one method of attaching the rings thereto. Fig. 4 is a cross section of the stationary ring-rail having a ring attached. Fig. 5 is a detail in perspective showing a flanged block forming a portion of my improved method for adjustably connecting the rings to the stationary ringrail. Fig. 6 is a detail plan view of an arm to which a ring may be'attached and by which said ring may be connected to the stationary ring-rail.

Similar reference-letters designate corresponding parts in all the views.

A represents one of the end, and A one of the horizontal end, connecting portions of an ordinary wool or cap spinning frame, said part A being perforated for the reception of the vertically-movable spindles B.

O is a bar to which the spindles B are connected and upon Which are mounted flanged pulleys D, which carry the bobbins E, said bobbins being driven by the belts d, which connect a pair of the pulleys D with a suitable driving-pulley, (not shown,) and 0 represents one of the usual cam-operated rods attached to said bar 0, causing said bar and the bobbins thereon to rise and fall as required.

F represents the rings, which may be each secured to an arm G, and for the purpose of adjusting said rings either to the right or left, so that they shall be concentric with the spindles, I provide the intermediate flanged plate H, resting between said arm G and a stationary ring-rail I, to which said arm and plate may be secured in the following manner: The arm G is provided with an elongated opening g for the passage of a clamping-bolt, and so, also, is the stationary ringrail I provided with elongated openings 2', while the plate h has a central perforation h, and a suitable bolt J is provided whose func* tion is to clamp the arm G and plate H to said stationary ring-rail I in whatever position desired. The said plate H is also pro vided with flanges 7t on two opposite sides, between which rests the arm G, and with flanges 71 on its other two sides and projecting in the opposite direction to those made to receive the arm G, said flanges if being adapted to close over the edges of the stationary ring-rail. Thus it will be seen that to adjust a ring F sidewise the flanged plate H must be moved upon the ring-rail I and to adjust a ring forward or backward the arm G must be moved upon the plate H, af-- ter which the bolt J may be tightened to readily maintain the proper adjustment of the said arm G and plate 1-1, the movement of these parts being made possible by reason of the bolt J passing through the elongated openings g 2', respectively, of the arm G and ring-rail I and through the larger central perforation 7L in the plate H.

It is obvious that the ordinary ring-rail used in cotton-spinning frames, if made stationary, will serve a very good purpose in carrying my invention into practice; but after many experiments I am of the opinion that to place the stationary ring-rail back of the spindles, attaching the rings thereto in the manner herein shown and described, is preferable.

Chief among the advantages gained by the adoption of rings in substitution for the caps in Wool-spinning is that the spindles can be run at much higher speed, thus winding the bobbins tighter, which means more yarn on a bobbin, with fewer knots, and the advantage of a stationary ring-rail over a movable one is that the length of yarn between the rolls and the traveler on the ring is substantially uniform at all times, thus decreasing the liability of its breaking.

Having described my invention, what I claim is 1. In a spinning-machine, the combination upturned flanges on two opposite sides of the block standing astridethe arm, as and for the purpose set forth.

2. In a spinning-machine, the combination with a series of spindles, and a ring-rail adjacent to and parallel with said series, the rail having openings opposite the spindles elongated in the direction of its length; of a ring for each spindle, an arm supporting each ring and resting upon the rail at substantially right angles thereto, this arm having an opening, a clamping-bolt engaging such opening and one in the rail, ablock between the arm and the rail pierced with a perforation through which the bolt also passes, and downturned flanges on the two opposite sides of the block standing astride the rail, as and for the purpose set forth.

3. In a spinning-machine, the combination with a series of spindles, and a ring-rail adjacent to and parallel with said series, the rail having openings opposite the spindles; of a ring for each spindle, an arm supporting each ring and resting upon the rail at substantially right angles thereto, this arm having an opening, a clamping-bolt engaging such opening and one in the rail, a block between the arm and the rail pierced with a perforation through which the bolt also passes, upturned flanges on two opposite sides of the block standing astride the arm, and downturned flanges on the remaining two opposite sides of the block standing astride the rail, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

AMARIAH AVERY.
