SPINNING AND TWISTING FRAME.

SPECIFICATION forming part of Letters Patent No. 653,638, dated July 10, 1900.

Application filed May 2, 1900.

To all whom it may con/cern:

Be it known that I, SIMEON BERAED, a citizen of the United States, residing at Fall River, in the county of Bristol, State of Massachusetts, have invented a certain new and useful Improvement in Spinning and Twisting Frames, of which the following is a specification, reference being had therein to the accompanying drawings.

The aim of the invention is in general to enable the use of the ordinary ring and traveler to be dispensed with inthe spinning and twisting of yarns.

The invention consists in a rotating ring` driven by band and drum, or it may be by other approved means, and provided with a movable guide through which the yarn passes to the spindle or bobbin, combinedwith novel and improved means of supporting the ring, in a rotating ring such as aforesaid, provided with a novel form of yarn-guide, and in novel arrangements for spinning or twisting, including a rotating ring such as aforesaid.

The invention will be described first withv reference to the accompanying drawings, i-n which latter I have represented the best embodiments of the invention which I have thus far contrived, after which the characteristic features of the invention will be found particularly pointed out and distinctly defined in the claims at the close of this specification.

In the drawings, Figure 1 shows in elevation certain portions of a frame for spinning or twisting, illustrating the best form in which I have thus far contemplated reducing the invention to practice'. Fig. 2'shows`in transverse vertical section a rotating ring, its yarn-guide, the support forthe ring,=and the rail to which the said support is applied. Fig. 3 shows in plan a ring and its yarn-guide. Fig. 4 is a detail view in section on avertical plane, showing the upper part of the ring and the movable yarn-guide applied thereto.

Having reference to the drawings, 1 designates a spindle, and 2 the support containing the bearings for the spindle, the said support and bearings being of any suitable and approved character and construction Aand the spindle being adaptedto turn in the same in Serial No. 15,184. (No model.)

response to strain transmitted through the 5o yarn, as explained hereinafter.

3 is the spindle-rail, to which the said sup# port 2 is applied.

4 is the ring-rail. 5 is a ring applied to the ring-rail 4 and ein- 55 ployed in connection with the said spindle l.' The said ring 5 is grooved in its exterior, as at 6, to receive a driving-band 7, Fig. 1.

' 8 is a thread-board above the upper end of spindle l, and 9 is a guideeye carried by the 6o said thread-board in line with the said spindle.

' 10 is a yarn-guide which is applied to the ring 5. Y

The yarn is indicated at 11, it being represented as passing in customary manner through the guide-eye 9, thence down to. and through the thread-passage of yarn-guide 10, and thence toward the spindle l. -The yarn-guide 10 is connected movably with the upper end of ring 5, as by means of 7o a pin or screw 12, fitting an eye 13 in one end of the said yarn-guide. The yarn-guide is free to swing upon this pin o r screw asupon a pivot and in the practical working of the invention as the ring rotates is caused to move thereupon by the pull of the yarn as it winds upon the spindle andV by the centrifugal force that is generated by the rotation of the ring. i

In the normal working of my invention the 8o yarn operates to hold the guidingl end of the yarn-guide in close against the surface of the yarn-receiver surrounding spindle 1, or the yarn-load thereon. This obviates practically allY tendency to breakage of yarn between the 8 5 yarn-guidelO and the spindle in starting up a spinning-frame after the stoppage thereof or in slowing down, since the pull that is transmitted from the ring 5 through the yarn-guide 10 and yarn is applied practically at the sur- 9o face of the yarn-receiver or yarn-load and through a minimum length of yarn instead of being applied through a considerablelength o f yarn, as would be the case if. the yarnguide were fixed at or near the periphery of the rotating ring. It will be perceived that the yarn in being spun'or twisted describes a cone having a base of the minimum diame`1 ter, and consequently ballooning of the yarn to a troublesome extent is rendered impossible.

In order to prevent the yarn from escaping from the thread-passage of yarn-guide 10 as the frame is slowed down, stopped, or started again, which would necessitate rethreading of the yarn and also occasion kinkin g, breakage, and other troubles, I provide the entrance t0 the said thread-passage with an elastic keeper 100. This keeper normally closes the said entrance. It is yielding, and hence permits ready ingress of the yarn as the latter is being threaded up by the spinner, but effectually prevents accidental egress of the yarn. In the illustrated form the said keeper consists of a small spring-strip which is secured by one end thereof to the yarn-guide, its free extremity extending across the entrance of the thread-passage and into contact with the free end of the hook of the yarn-guide.

In accordance with one feature of the invention I provide the ring 5 with a cylindrical portion 131 at its exterior preferably by forming the upper end of the ring at its exterior with an upwardly-extending shell 14. It is necessary to stop the rotation of the ring from time to time in the working of the frame in which it is employed without arresting the working of the frame itself. This is done for the purpose of enabling the attendant upon the frame to piece up the yarn 11 whenever necessary and for other purposes. The cylindrical portion 131 enables the spinner to effect the said stoppage of the ring conveniently whenever required simply by clasping said portion with thumb and finger or otherwise producing pressure and friction thereupon by hand. The upwardly extending shell 14 constitutes a stop which determines the extreme outer position of the yarn-guide 10 and serves in the illustrated embodiment of the invention to prevent the said yarnguide from flying out too far under the influence of centrifugal force when the yarn becomes slack or breaks. The said shell also shields or protects the yarn-guide from conthe upper surface of ring-rail 4 around the said hole. The lower end of the bearing-ring 15 fits within the upper end of the holder 16, and these parts are correspondingly threaded and screwed together, as shown. A shoulder 20 upon the bearing-ring 15 is provided for the purpose of resting upon the shoulder 21 on the holder 16 when the parts have been properly upon the shoulder 21 of the holder.

screwed together. The interior of ring 5 takes bearing against the exterior-of bearingring 15, while the lower end of the ring 5 bears Being separate and detachable, the bearing-ring 15 is capable of being removed when necessary for any purpose and of being replaced by an'- other one when worn. or injured. The holder 16 is formed with a groove 22 ybelow the bottom flange or skirt of the ring, which groove is designed to receive oil for the lubrication of the bearing-surfaces of the rotating ring, bearing-ring,and holder. The upwardly-extending portion or flange 23 outside the said groove slightly overlaps the said skirt or flange of the rotating ring in order to prevent escape of the oil under the action of centrifugal force, as well as the entrance of dust, flyings, tbc. From the groove 22 the oil -works its way upward to the said bearing-surfaces.

At 24 is shown a band of yarn or other suitable material for absorbing the oil and slowly giving it out to the bearing-surfaces, the said band being applied to the upper portion of the holder 16 in connection with groove 22.

25 designates a second band of yarn or other absorbent material applied to the exterior of the bearing-ring 15. For the reception of the said band 25 the said bearing-ring is formed with a groove in its said exterior. Narrow bearing-surfaces to receive the contact of the interior of the ring 5 are left on the bearing-ring 15 above and below the said groove.

One or both of the bands 24 25 may be employed in practice, according as preferred. In some embodiments of the invention I contemplate the use of ball-bearings in connection with the rotating ring 5.

For the purpose of holding the ring 5 in place upon bearing-ring 15, so as to prevent accidental lifting of ring 5, the bearing-ring 15 is formed with a lip 26, projecting over a shoulder 27 on the ring. The said lip in the present embodiments of the invention is constituted by a circumferential flange extending outwardly from the upper end of bearingring 15, and the said shoulder is formed by rabbeting the upper end of the ring 5, the flange occupying the rabbet, as shown.

It will be understood that the spindle is not driven in the operation of the parts, it being caused to turn by merely the pull of the yarn as the latter is carried around by the rotating ring, and it will be understood also that the yarn becomes wound at the exterior of the spindle in consequence of the tendency of the spindle to rotate more slowly than the ring.

In spinning with a rotating ring such as that which has been described and a spindle rotated by the pull of the yarn it is found that as the lower portion of the spindle becomes filled with yarn and the winding on approaches the upper end or tip of the spindle there is an increasing tendency to breakage of the yarn. This is due to the fact that the transverse strain of the yarn ext-ending IOO IIO

through thevarn-guide l0 of the rotating ring to the spindle acts With gradually-increasing leverage upon the blade of the spindle and consequently with correspondingly-increased tendency to occasion binding of the lower end of the spindle within the bearing or bearings therefor. This produces a gradually-increasing resistance to the rotation of the spindle under the pull of the yarn.

For the purpose of remedying the foregoing drawback I apply to the rotatable spindle 1 a sleeve, as 3l, which is free to turn upon said spindle independently of the latter. Hence when the resistance to the rotation of the spindle increases the sleeve will still remain free to rotate upon the spindle, and thereby the tendency to occasion breakage of the yarn will be obviated. In order to prevent too free a rotation of the sleeve upon the spindle, the lower end of the sleeve is caused to bear upon a cloth or felt Washer 32 or the like drag device applied to the upper end of the support 2 for the spindle. In some cases the washer may be dispensed with and the lower end of the sleeve may be permitted to rest directly upon the upper end of the said support. For the purpose of preventing the sleeve from lifting in doffing a holdingdown pin 33 of usual character is arranged to extend over a ange 34 on thesleeve.

The sleeve 3l may be removable, together with the yarn-load, if desired, butusually I apply thereto a cop-tube or other separate yarn-receiver, as lll, and remove the latter when the required amount of yarn has been produced.

I claim as my inventionl. In combination, the spindle, the ring having the yarn-guide pivotally mounted at the upper end thereof, and means to rotate the ring, said ring having the upwardly-extending shell serving to shield the yarn-guide and also to arrest the outward swing of the yarn-guide and the exterior cylindrical portion to enable the spinner to arrest the rota tion of the ring by hand by pressing against said portion, substantially as described.

2. In combination, the holder having a shoulder at its upper end, the separate bearing-ring having the lip and also having a shoulder to make contact with that ofthe holder, the said holder and bearing-ring being threaded and secured together and the rotating ring revolving upon the exterior of the.
