CREEL.

Application filed June 22, 1925.

My said invention relates to a creel for supporting cheeses in warping and analogous operations and it is an obgect thereof to increase greatly the speed with which the yarn may be drawn off from the cheeses In such older forms of cheese creels the yarn is drawn ofl tangentially from the cheeses which are supported for free rotation byv means of roller bearings. with the result that the limit of safe travel of the yarn is about 1500 feet per minute while with my devlce the speed may be increased by 525 feet or more per minute.

Anothe object of my invention is to simplify the structure of the creel.

Referring to the accompanying drawlngs which are made a part hereof and on which similar reference characters indicate similar parts,

. Figure 1 is an elevation of a part of a creel,

Figure 2, a plan of such part,

Figure 3, a fragmentary elevation showing a single cheese and the neighboring parts of the creel on a considerably enlarged scale,

Figure 4, an elevation at right angles to Figure 3 and on a smaller scale,

Figure 5, a horizontal section of parts shown in Figure 4 with two cheeses in place instead of one, and

Figure 6, an elevationsimilar to Figure 3 with the cheese supporter in section.-

In the drawings reference character 10 indicates a floor member of a creel frame having uprights 11 and 12. The uprights 12 are in the form of rods which support horizontal bars 13 secured to the rods 12 at intervals in any conventional or desirable manner. The bars 13 are here shown as supported midway of their length and as being provided adjacent each end with a post 14.

The posts 14 are shown as relatively short and cylindrical and terminate at their upper ends in conical reduced portions fitting in the hollow interior of a cheese support on.

which a mass of yarn, indicated at .15, is wound in well-known manner. The cheese support comprises a hollow spindle composed of an inner sleeve 16 and a loose outer sleeve 17 surrounding sleeve 16. Heads or flanges 18 are provided at each end of sleeve 16, the sleeve being flared at one end to hold in place the head at the upper end of the spindle in Figure 6, which head has a part Serial No. 38,836.

crimped over a flange on a thimble 19 to secure the thimble in place. The head 18 at the lower end of the spindle in Figure 5 is held in place by a nut 20, and the sleeve 17 serves as a spacer to limit the inward move ment of the heads. Ball retainers carrying rollers 21 and 22 are supported'near opposite ends of the cheese supporter between the shoulders of the spindle just described and shoulders on a shell 23 'freely rotatable on the spindle. At its upper end the shell supports a thimble 24 held within a protruding end flange at 25, this being the counterpart of another end flange 25 at the other end of the cheese supporter. The structure so fardescribed is of advantage in the winding of the cheese which is done with the axis of the supporter horizontally located on a wellknown type of: winding machine and also for upholding the cheese supporter in the ordinary type of creel where it rests on an end flange of the thimble 19 so that the shell and the cheese may rotate about the spindle as the yarn is drawn oil tangentially, the roller bearings being so arranged as to permit free rotation during this operation and also to permit the shell to rotate freely when the spindle is 'held with its axis horizontal in the operation of winding on.

Bars 26 are supported on the rods'12 at some distance above the bars 13 and the bars 26 support the guiding and tension devices which may be of the disk type with a fixed disk 27 and a loosely mounted disk 28. An abutment 29 limits the upward movement of the loose disk and the yarn passes through a guide opening 30 (Fig. 5) in the bar 26, then under a drop wire 31 pivoted at 32 on a standard 11, then over a fixed supporting wire 33 (Figs. 3 and 5), and so to the warp beam or other yarn receiver.

The uprights 11 are grooved longitudinally to receive conductors 34 and are cut away at intervals to expose such conductors so that in case of breakage of a yarn the lower free arm 35 of the drop wire 31 may engage both wires 34 to close the circuit through a stop mechanism not forming part of the invention claimed herein.

By positioning the cheese and ,its supporter, as indicated in Fig. 6, with the post,

of action and the weight of the yarn mass will be supported directly on the bar 13, the post 14: serving merely to position the cheese and prevent accidental dislodgement of the This will cause it to rcevc of? freely from the periphery of the cheese and it can be drawn off at great speed, as above explained, with out danger of breaking the yarn.

It will be understood that various vtypes .of supporting devices for cheese-wound yarn-masses may be substituted for that shown in the drawings without losing the advantages gained by the use of my device. It is characteristic of the vdevice here illustrated that the Weight of the carrier and the cheese is such as to maintain the necessary frictional engagement with the shelf or bar until the yarn-mass is unwound to the desired extent. In practice a certain amount of yarn is always left on the carrier for attachment of the yarn to be wound on. The tendency of the unwinding yarn to rotate the carrier or to tilt it laterally is obviously greatest when the cheese is largest but the.

weight at this time holding the carrier with the end flange or rim 25" in engagement with the bar or shelf 13 is also greatest at this time and both these factors decrease as the yarn mass decreases in size.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit'of the, invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is: I

1. A creel adapted to support a yarn holder having a yarn-mass bearing shell, a spindle therein, anti-friction bearings be tween the shell and spindle comprising a support for the yarn holder, means on the each of said osts substantiallv as set forth.

' 3. A creel comprising upright rods, transverse bars carried by said rods, posts on said transverse bars, the said posts and oars oeingadapted to support cheese supporting means comprising a hollow spindle surrounding the post, a shell about the spindle having frictional engagement with the said bar, and anti-friction devices between the shell and spindle, substantially as set fortlrl I. A oreelcomprising upright rods, transverse bars supported by said rods, posts on said bars, a yarn guide spaced from the post and located approximately in axial aline- Inent therewith, the said bars and posts-bee ing adapted to support cheese supporting means and prevent its rotation such as a spindle surrounding the post, and a shell surrounding the spindle with anti friction bearings between the shell and the spindle, substantially as set forth. V

5. A creel comprising an upright rod, a

horizontal bar on said rod, an upright post on said bar, a yarn guide above the bar in substantial alinement with the post, the said post and bar being adapted to support and frictionally prevent rotation of a'cheese supporter which includes a spindle and a shell normally rotatable thereon, substantially as.

set forth. 6. A creel comprising an upright rod, a shelf carried thereby, a post thereon, the said post being adapted to carry a cheesewound yarn-mass having an opening fitting loosely about the post, the said'yarn-mass having a rim resting on the shelf whereby it is held against rotation, substantially as set forth. I r

In witness whereof, I have hereunto set my hand at Chattanooga, Tennessee, this 8th day of June, A. D. nineteen hundred and twenty-five.
