RING-SPINNING FRAME.

fiPECIFICATION tanning part of Letters Patent No. 340,159, dated April 20, 1886.

(No model.)

To aLZ whom, it may concern.-

Be it known that I, MORTIMER SHERMAN,- of Lowell, county of'Middlesezgand State of Massachusetts, have invented an Improvement in RingSpinning Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. 7

This invention has for its object to provide the blade of a spindle with a top support, or a support located at a point above the nose of the bobbin, placed on and rotated by the spindle, to thereby steady the latter and enable it to be run at high speed without gyration.

In ring-spinning frames as heretofore made, wherein the bobbin is caused to travel with the spindle by reason of adhesion the one to the other, the top of the blade of the spindle has not, so far as 1am aware, been supported at a point above the nose of the bobbin, but has terminated below a guideeye connected with a hinged guide-board. It is well understood that the yarn being twisted by the rotation of the spindle is made to wind upon the bobbin by reason of the slower rotation of the traveler, it being held back by its friction on the race of the ring. The greater the ditierence between the number of rotations of the spindle and of the traveler on the race, the faster the thread or yarn will be wound on the bobbin. In the ordinary spindle, unsupported above the bobbin, the thread or yarn swings about the top of the spindle and bobbin within and below the usual guide-eye, the said thread or yarn extending from the guide-eye to the traveler. If the number of rotations of the traveler and the spindle were equal, the thread or 'yarn might rest on the top of the spindle at one point and remain at that exact point; but under such circumstances the thread or yarn would not be wound upon the bobbin. To wind the thread or yarn on the bobbin, the winding being effected by reason of the less number of rotations of the traveler as compared with the number of rotations of the spindle, it will be obvious that the thread or yarn, if it rested directly against the top of the spindle,would have to rotate about the spindle, and therefore the spindle could not have at its top a sleeve like support, such as provided for it below the bobbin.

1 have ascertained by experiment that the spindle may be effectually supported at its top above the bobbin, provided the top of the spindle is grooved or channeled at a point within the top bearing employed to steady it. and provided the said top bearing is slotted or notched, to thus permit the thread or yarn as its twist and its tension increase to slip out of the groove or channel of the spindle when opposite the slot or notch of the top bearing, the thread or yarn falling again into the groove or channel of the spindle when the said groove or channel in the faster rotations of the spindle again overtakes or comes opposite the thrcad or yarn, the thread or yarn slipping out and in the said groove or channel and permitting the thread or yarn to travel about the top of the spindle independently of its rotation with the spindle, or to travel in the same direction as the spindle, but at a slower speed.

Figure l of the drawings in vertical section represents a suificient portion of a ring-spinning frame to enable my invention to be understood, the said figure showing in section the top rolls, roller-stand, guide-board, top bearing, ring, ring-rail, step, and step-rail, the bobbin and spindle being left in elevation. Fig. 2 is a vertical section of the top of the spindle in the line at m of Fig. 3; Fig. 3, a top view of the spindle; Fig. 4, a top View of the top bearing for the spindle detached from the guide-board, and Fig. 5 a modification showing a guide-eye on the guide-board.

The roller stand A, front rolls, A A, hinged guide board B, ring 0, ring rail 0, traveler T, step S, step-rail S, and bobbin D are all substantially as usual, and in practice the top rolls and the ring-rails will be operated as common in ring-spinning frames.

The spindle E, supported at its lower end by the step S, is provided with a whirl, E, to receive the usual spindle-driving band. (Not shown.)

The guideboar'd is provided in accordance with my invention with atop bearing, G, made,

at g, the bearing being sechred in a concavity made in the said guide-board, the latter being hinged at a, to be turned up when a full bobbin is to be dotted from or an empty bobbin is to be applied to the spindle.

The top of the blade of the spindle E is extended up into the top bearing, G, and is grooved or channeled, as shown at b, to receive the thread or yarn t between the front rolls and the traveler T, the thread or yarn being kept in contact with the top or upper part of the spindle, but in such manner as not to be cut off, broken, or coiled between the spindle and its top bearing.

The spindle having its upper end placed in a top bearing, as shown, is steadied at its top, thus obviating excessive gyration of the said spindle and enabling it to be run at high speed without necessarily employing the usual loose or movable lower bearings, and without employing a support for the spindle within the base of the bobbin.

The groove or channel b in the spindle, and the slot or notch g of the top bearing afl'ord spaces for the temporary escape of the thread or yarn from the groove or cnannel of the spindle into the slot or notch of the top bearing, and vice versa, as the spindle is being rotated. to thus permit the thread or yarn to fall behind the spindle or not to rotate as frequently as the spindle, such difl'erence in rotation effecting the winding of the yarn on the bobbin.

I wish it to be understood that I may, if desired, pass the thread or yarn through a guide eye, as at B, Fig. 5, between the front rolls and the top of the spindle; but I prefer to dispense with the guide-eye and let the twist in the thread or yarn extend from the top of the spindle to the front rolls. The employment of the guide tends to prevent the free passage of the twist above it.

7 I do not desire to limit my invention to the particular form shown of top bearing. and instead thereof I may employ any usual or wellknown equivalent bearing. Nor do I limit my invention to any particular form of step.

In my invention it will be noticed that the ordinary ring-frame bobbin may be employed.

I do not claim abobbin provided with a grooved tip extended up into a support or guide of a guide-board.

In the process of'producing yarn the yarn as spun is moved upon bobbins carried by spindles, and the bobbins when filled are dofi'ed from the spindle and thrown into a box supported upon wheels, and this'box when more or less filled with bobbins is rolled into the spooler-room and its contents are poured into the spooler-box, from which latter the bobbins are thereafter taken and applied to the spooling-frame, and the yarn having been drawn from the bobbins the latter are thrown into a box and rolled back to the spinning-frame, to be again put upon the spindles of the spinningframe.

In handling and throwing the bobbins, as described, should they be provided at their upper ends with metal tips, the latter would become bent out of straight line with relation to the center of the bobbin, and the tips would frequently be broken from the bobbins. In case the tip atthe end of the bobbin be knocked loose or be bentout of its true central relation to the bobbin it would be impossible to make good yarn.

By providing the end or tip of the blade of the spindle with notches, as herein described, it is possible to employ ordinary bobbins, and there is no liability of bending out of shape or of injuring the notched top thereof, extended above the bobbin.

I disclaim any combination shown in the application of Charles H. Chapman foran improvement in spinning-spindles, filed December 24, 1884, in which the upper end of the spindle is not provided with a steadying-bear- 111g.

I claim 1. The step, the rail to support it, and the spindle provided at its top with a groove or channel, combined with a slotted or notched or open bearing for the top of the spindle, and with a support forthe said bearing, the combination being and operating substantially as described.

2. The step. the step-rail, and the spindle having a longitudinal groove or channel in its top and extending up into the guideboard, combined with such guide-board, and a slotted, notched, or open bearing for the said top oi said spindle arranged in said guide-board, substantially as shown and described.

In testimony whereofl havesigned my name to this specification in the presence of two subscribing witnesses.

MORTIMER SHERMAN.
