To' all whomz't may concern Be it known that I, CLAES RYDnN, a citizen of the United States, vresiding at Providence,`in the county of-Providence and State of Rhode Island, have invented certain new and usefulIln rovements in Reels or Swifts, of which the fiillowing is a specification.

My invention relates to improvements in y reels, swifts or similar devices used for holding skeins in unwinding the same to deliver the yarn to winding or other textile machines.

My improved swift or reel is particularly adapt-ed for use Where the skein-holder is rotated to unwind the yarn and provided with means to control its rotation and automatically regulate the tension ofthe delivering yarn.

The object of my improvement is to provide a more effective holding surface on the swift or reel, so that the latter will be positively rotated by the draft on the yarn, and even when the skein is nearly run oft' the last few coils will still cling to the reel to continue its rotation as required to maintain the tension on the arn.

The invention is fu ly set forth in the following specification, illustrated by the accompanying drawings, in which Figure l is a view of a winding machine showing a skein-unwinding device in which my improved form of reel is employed; Fig. 2, an isometric projection of the reel or runner in its preferred form; Fig. 3, a similar view of another form of skeinholder or swift In Fig. 1 I have shown a usual form of 4 windin machine designated A with a skein- `irnwin ing device applied thereto similar to that described in my pending application, Serial No. 577,597, filed August 17th, 1910, from which-the present case is divided. The

winding machine A has horizontally projecting spindles c on which the bobbins b are wound and the thread or yarn is trav- .ersed b a thread-guide d reciprocating opposite t e spindleand feeding progressively outward to build up the conical layers of winding.

'As described in detail in my previous ap.

i plication above referred to, the skein-unwinding `device here shown is carried on the A-shaped brackets B which surmount the,

top of the frame of the machine. The brackets B support horizontal rods or bars e and 7' and on the bar e are mounted arms E which have bearings for the reels or swifts. I have here shown the device arranged for reels, or runners as they are generally termed, similar to that illustrated in Fig. 2. The upper runner R rotates on a stud 1' held in a bearing on the arm E and the lower runner R is rotatably supported on an arm F hinged on the bracket Gf# The bracket G is mounted on a standard h extending upwardly froxn a bracket H -fastened to the rod y. The skein S is stretched over the two runners R and R and, preferably, the arm 'F is held down by suitable frictional tension means to draw the coils of the skein taut. The draft on the yarn as it is taken up by the Winding o eration causes the two runners R and R to rotate and its delivery from the skein. is regulated by controlling the rotation ofthe larger runner R. The controlling means for the runner R is shown and described in detail in the application before referred to and therefore requires no specific description herein. In general, the mechanism consists of a spring take-upA arm t operated by pivoted or fulcrumed on the stud 1' on which Y the runner R rotates. At its outer extremity it carries' a guide or .pi'g-tail t through which the yarn y draws from the skein. From the ide t .the yarn .leads down through anote1 the end of a secondary spring arm a', which provides an auxiliary yielding element, and n.

thence to the traverse thread-guide d. A V-shaped truss-like extension 't2 is secured r guide z' supportedat i" to the upper end of the arm t to serve as a stitlening nieans, so that the arm will not.

bend throughout its whole length, andA to this extension is secured the rotation controlling means for the runner ZR. This coni siste-of iiexiblebrake-band's arranged to .surround and frictionally engagethe periphery of a brake-drum -0 which 1s formed on the hub of the runner R. One end of the band -s'is fastened'at t3 to an -ofl'set finger, vnot here shown, on the 'extension t2 and to its opposite'extreniity is secured a coiled spring The jother end of the spring u I is. secured by. aclamp o to the inclined portion #of the' extension t2. -The' clamp o 1s' fastened by a'set screw o which provides foradjustingthe'clamp along Athe incline t4 to vary-'the tension ofthespring u and also the extent of contact of the brake-band with itsl extremity heldin a slot at the end the periphery of -the drum o.` A flat, springtemperedarm w extends from the .end of the arm downward along the arm E with of the rod The rod V:ris adjustable longitudinally vin a lug e5 on the arm E and heldkby a set'screw By sliding the rod in the lug e5 the vspring w may be engaged at different points along its length to vary the effect ofits spring action -on the arm't.

. Referring to Fig. 2 the reel or runner R is constructed with a hub 2 formed with end flanges from which project. two series of wire spokes 3 supporting the two parallel,

' annular-rims 4 and 5. Each pair of spokes is formed of one length of wire extending radially outward from o-ne end of the hub 2,

v across the rims 4 and 5 and backl into the other end of the hub. The wire is doubled back in loops to iinpinge uponthe rims 4 and 5 and extends across in the bars 6 to bridge the space between the rims. In this way two flanges are provided on the oppo- I v site sides of the reel adapted to retain the 'auf known and have inertia of the l latter vmust be overcome ora f when the reel is restrained from free rotation by the tension controlling devices. To

guard against this condition andfprovide a more eiicient holding surface for the skein I apply a band 8 of felt, or other rough-sur# .faced fabric, leather or similar material,

stretched around the cross-bars ''as shown particularly in Fig. 2. This gives a continuous, peripheral, gripping surface around the circumference of the reel and effects a frictional engagement between the skein and the band 8 which prevents the coils from slipping. Even whenthe skein has nearly run oli and there are but two or three coils remaining, these few coils will cling to the surface of the` band 8 and rotate the reel to effect its proper control through the tension 0r brake devices.

reel or runner R only, but if desired a simllar band might be applied to the other runner R. It 1s not absolutely necessary, how ever, for the lower idler runner R to be rotated constantly with the movement of the skein. The braking and tension-controlling devices .coact with the upper runner R, as previously described, and therefore this runner must be driven positively by the ldraft on the arn, the other@ runner being driven as an i ler. It has been demonstrated that the friction surface of the band 8 will insur positive rotation even down to the last few coils ofyarn wrapped around the runners.

The operation of the whole device is as e lfollows: The skein S is stretched over the runners'R and R and the arm F pressed ldownward to draw the coils of yarn taut.

The friction bearing of the arm F on its position and the yarn y is led from the upper runner through the ide t and thence down throughthe auxillary guide a to the thread-guide d. When the machine is startdraft on the yarn pulls the arm t bodily vIn Fig. 1 I have shown the peripheral band 8 applied to the upperv bracket G maintains the arm in its adjusted downward and the latter acts through the lbrake-band s to initiate the rotation of the against the resistance of the spring u and' tightens the band around the brake-drum o.

The spring u is adjusted to givey a frictionalv contact of theband on the drum sufficient to rotate the latter when the band is moved circumferentially around its axis and thereby the runner R is rotated to start the unwind; ing of the yarn. After the inertia of the runners hasbeen overcome by the impulse exerted through the movement of the arm t the draft on the yarn is sufficient to keep the runners turning and the arm t returns to its normal position under action of the spring extension w. The brake-bandy s normally has a contact with the periphery of the drum o sutlicient to apply a slight braking tendency so that the runners will not gain impetus and run ahead of the draft on the In thisy icov last coils of of draft on the yarn and the skein can be unwound to deliver the yarn without break or hindrance.

The improved reel or runner shown and described is articularly adapted for use in unwinding slieins of silk, or other smooth and slip ery materials, and is especially effective or controlling the delivering Syarn orthread down to the last coil in the ei Heretofore, with the usual form of reel, the the skein would slip around the circumference and unwind without tension and were apt to fall down and become tangled in the machine. Furthermore, unless a tension is maintained up to the end of delivery the layers of the bo bin will be y' poorly wound, becoming loose or sloughing oi, and thereby causing waste of material and loss of time.

In Fig. 3 I have shown another form ot reel generally called a swift, used for holding the skein without the employment of an auxiliary runner. This form of reel is intended for use with controlling mechanism similar to that shown and described in m application for patent, Serial No. filed October 23rd, 1909, and in reel R, reviously described. In this form of reel t ere are two sets of spokes 9 radiating from the opposite ends of the hub' 10 l vand their outer ends are connected by the twisted loops of cord l1. My improve?. ment is applied by stretching the fabric band 12 around over the cords 11 and the band takes a polygonal shape with the skein conforming thereto. As with the previously described form of rffael, the rogl fait;- ric 'ves a grip ing sur aceto w ici t e coilsg1 of the skeiil cling g Having now described my invention in so that V.the swift can be rotated by the draft on the yarn.

full and set forth the manner in which it is made use of for attaining the improved result shown, what Iy claim is 1. An improved reel 4or runner for skeinunwinding devices comprising a hub, two series of spokes radiating therefrom in pairs, cross members connecting the ends of each pair of spokes and a fabric band stretched around the cross members to provide a frictionsurface for the yarn.

2. In an improved reel or swift for skeiny unwinding devices, the combination with the hub-and spokes, of a peripheral band of frictional material ,extending around the swift .in` polygonal formadjacent the ends of the spokes to provide a holding surface for the coils of yarn.
