F, F, F, vare the countertwisty pulleys,

which'performthe twist bymeans of their peripheries. v"These pulleys 'consist each of a? short cylinder of metal with a band` e, of

woolen `clotliwaround Aits periphery. They arey securedupon parallel axles` a, a, c, which are placed atlright :angles to theaXles of the drawing. rollers, andparallel tothe rovlng, as `it `passesufrom the Vback to thefront axles neXt the front drawing rollers; rand their peripheries just touch yeach `other lightly. They are 'caused to `revolve all in the samedirection "by bands Z2, from the drawingrollers,being at those ends of the cylinder C, running over pulleys c, c, c, on

theirtaxles `and each roving passes between two ofthemvat or near their'point of contact and ireceives the twist in consequence t of the contiguous portions of the rollers moving in opposite directions. ingsof the spindles a, a, are in bridges H, H', secured to the Stop of the framing A. i

i The lfront drawing rollers E, E, E', E, `are placed so' close to the fronts of the The `bearcountertwist pulleys as nearly to `touch 30 them. The bed rollers E, E, are covered and are `made of about the usualdiameter of covered drawing rollers, as covered rollers can not lwell besmallenbut the top` rollers are iiuted and'mde much `smaller-not 85 more than half the diameterin order that .they mayget their bite as close as practicable tothe countertwist pulleys, or nearer thereto than the length of the bers.-` The journalsof the' bed rollers work in fixed 90 `bearings e, e, and receive rotary=motion by abelt which is not shown inthe drawings. The top rollers have their journals working inbearings in the ends of levers G, G,

which work on X`ed fulcra al, d,in brackets 95 f, 7, secured to the framing. These levers have weights g, g, suspended from them between their fulcra and the top rollers, in

order to draw thetop rollers down upon the bed rollers and give them sutlicient bite.

carrying fingers h, 7u, of which there is one for each spindle of the spinning frame, for the purpose of regulating the countertwist and preventing too great a degree of twist getting back to the large part of the roving near the back drawing rollers, which is done by the fingers giving an angular direction to the roving as illustrated in Fig. 1, where the roving is represented in red color passing over the finger. The bridge is supported at its ends upon the framing by screws z', z', by which it can be adjusted higher or lower, and the fingers are adjustable separately, being each attached to the bridge by apivot 5, at one end see Fig. l, and having not far from'the said pivot a female screw, receiving a male screw j, which rests upon the bridge and serves to raise or lower the finger. By carrying the roving in an angular direction over the finger It, too much twist is prevented passing the said finger toward the back rollers, and the twist is caused to be gradual and to increase in about the same proportion as the roving is reduced by drawing, which is the true principle to be observed in wool spinning. Vithout this bridge the countertwist would extend into the full sized roving to such an extent as to prevent its drawing easily and regularly. The twist can be regulated with great nicety by the adjustment of the bridge and fingers before spoken of to increase or diminish the angle in the roving; the increase of the angle having the effect of further preventing the countertwist extending back into the large part 0f the roving, and the diminution of the angle having a contrary effect.

The angular directidn may be given to the roving either downward or laterally instead of upward as shown, by proper arrangeL ments of a bridge and fingers or some devices equivalent thereto. In order that in starting or after mending the roving, it may receive a partial twist to enable it to bear being drawn in the angular direction, a sufficient space is left between the fingers and the bridge, by following the bridge as shown at lo, 7c, in Fig. 4, or otherwise to allow the rovingY to be conducted directly from the back to the front rollers, as shown dotted in red color in Fig. 1. As soon as sufficient twist is given, it merely requires to be passed by hand over the end of the finger on to the top.

Z, Z, are the spindles driven as usual by bands m, from the main cylinder, n, n, are the bobbins, I, is the ring'plate, and o 0, are the ring travelers all of the usual construction. The ring plate is operated upon to lay the cones on the bobbins in a well known manner by a lever J, and a cam K, on a shaft M, see Fig. 1; the lever being varied to vary the ring plate by means of a screw L, carrying a nut N, to which the lever is attached; and the said screw receiv ing a constant rotary motion through a band 79, from a pulley on the shaft M. A drag is produced upon the ring travelers when winding on the large part of the cones, by means of a series of brushes g, g, which are secured by binding screws r, 1', in sockets s, s, in a beam O, which extends the whole length of the frame and is hinged at each end or at proper intervals by hinges t, t, to the back of the ring plate. One of the brushes stands opposite every ring u. The beam O, has a small eye o, at the back near one end, which receives a rod w, standing up rigidly from a lever P, one end of which works on a liXed fulcrum attached to the framing and the other receives a screw y, which rests upon a cam Q, on the shaft M. The lever P, receives a vibrating motion from the cam, and the rod fw, is thereby caused to impart a vibrating motion to the brush beam O. The cam Q, is so arranged relatively to the cam K, that as the ring plate rises the brushes g, g, will fall back from them, and as the plate descends, the brushes advance toward the rings. The brushes are so adjusted by the screwing up or ydown the screw 1', in the lever P, that when the ring plate descends and the winding is being performed on the lower part of the cone, the travelers will during their revolutions come in contact with and receive a drag from theY ends of the brushes. As t-he ring plate rises and the brush beam falls back, this ydrag will be diminished and finally before the rail reaches the top of its movement the brushes will leave the traveler quite free. By thus producing a drag on the travelers while winding the large part of the cone, the tension on the thread, and the tightness of the winding may always be rendered uniform, but without such drag an uniform tension cannot be kept up, as the traveler will run so much easier while winding the large part than while winding the small part of the cone. The tension may be regulated exactly by the screw y, in the lever Q. Instead of the brushes g, g, pieces of leather or other soft or elastic material may be used.

The method of regulating the tension of l.the thread during the winding enables a larger bobbin to be used and prevents breakage.

What I claim as my invention and desire to secure by Letters Patent is- 1. Conducting the roving from the back to the front drawing rollers by employing a bridge (or rest) with fingers upon it situated between the front and back pairs of drawing rollers for the purpose of governing the counter twist, so as to adapt a smaller portion of it to the part of the thread nearest the back rollers.
