d R. C. LONGVALL SPINDLE FOR CREELs Filed April 30, 1925 nvwior Ra mond CL vail g5/0W k @Z13 UNITE BATES SFI FOR To all whom t may concern.'

Ee it known that l, RAYMOND C. LONG- iniLL, a citizen oil the United States, residat TEilforoester, in the county of lliforcester and Commonwealth oi l/iassachusetts, have invented a new and useiiul improvement in a Spindle for Creels, ot which the it'ollowing, together with the accompanying drawings, is a specification.

My invention relates to creeis or spool stands, such as are employed lor rotatably supporting a plurality or' spools or yarn packages so t-hat the yarn may be convenieirtlj,r led therefrom.

The object ot' my invention is to provide an improved spindle for rotatably supporting spool or yarn package in such a manner that the latter will not vibrate excessively as the yarn is led therefrom. The. spindles heretofore employed in creels or spool stands are usually inclined ironi the horizontal a certain amount, so that when a spool is slipped over a spindle it Will tend to seat a position near the base ot the spindle as it is rotated by the Withdrawal ol the yarn therefrom. rThe opening in the spool Which receives the spindle must necessarily be large enough to permit the spool to turn freely, and it has been found that as the opening in a Wooden spool becomes larger, by Wear, the spool Will tend to chatter on the spindle, due to the fact that the pull exerted by the yarn as it unwinds, is applied to first one end oii the spool and then to the other. `When a large number of spools are turning on a creel at high speed, the chattering of the spools then becomes most objectionable and tends to set up severe vibrations throughout the Whole creel.

Aaccording to the present invention l propose to provide an improved spindle so constructed that the end of the spool opening near the base of the spindle will make a close lit with a member carried by the spindle, so that play at one end of the spool. is substantially eliminated, regardless ot' the size oit the opening in the spool, and chattering does not occur.

rlhe above and other advantageous `teatures ot my invention will hereinafter more i'uv appeai, reference being had to the acuompanying drawings in which 1g l is i View in front elevation of a portion oi' a creel provided With spindles embodying my invention.

Fig. 2 is an enlarged 'ie-iv of one of my improved spindles removed from the stand orl the creel shown in Fig. l.

il ig. 3 is a. .longitudinal sectional view of the parts shown in Fig. 2.

Like reference characters refer to like parts in the different figures.

Referring to Fig. l, a portion or" a Creel frame is shown, which consists of upright members l with spindlebars 2 supported thereby and each carrying a number orn sinndles lThe bars 2 are so arranged that the spindles 3 extend therefrom with an. upward inclination from the horizontal, so that when spools or yarn packages 4 are placed on the spindles, the spools Will each seek a position near the point oi' support of the spindles 3 on the bars 2. A cross member 5 extends above eac-h row ot' spindles 3, and is provided with eyes 6 through which are led the individual strands of yarn 7 from the spools 4.

Referring now to Figs. 2 and 3, each spindle 3 is provided near its ends With cylindrical seats 8 and 9 Which are slightly less in diameter than the cylindrical opening l0 provided in the spool 4. The spindle 3 is proif'ided beyond the seat 9 With a reduced portion ll, thereby forming a shoul der l2. rlhe reduced portion ll is provided with a plurality threads 13 which extend to Within a short distance of the shoulder l2. The threaded end of the spindle 3 is received in an opening lll provided in the bar :2, and nuts l5 and 16 serve to clamp the spindle 3 on the bar 2.

sleeve 17 surrounds the unthreaded reduced portion ll and is free to turn between the shoulder l2 and the tace of the nut The outer surface of the sleeve i7 is conical in form, With the small end thereofA substantially flush with the seat 9. lV hen the spool 4 is slipped over the spindle 3, the small end. oi the sleeve if? will be received in the Spool opening l0, and the end of the opening l0 Will fit snugly upon the conical portion of the sleeve 17, the exact point of engagement between the spool 4f and the sleeve 17 being determined by the diameter of the spool opening.

When the spool 4C is rotated by withdrawal of the yarn therefrom, it is obvious that the lower end of the spool will always fit ,closely on the sleeve 17, and cause the latter to rotate therewith on the unthreaded reduced portion 11. Therefore, there is nc possibility or any play developing between the lower end of the spool and the spindle, so that the spool will always rotate without chattering. The conical surface of the sleeve 17 is of such length that it will lit into diderent sizes of spool openings, provided of course, the spool opening has not beenenlarged too much by wear. Any spool which has been worn to the extent that its opening is larger than the sleeve, would be uniit for use.

From the foregoing it is apparent that by my invention I have provid-ed an improved spindle for creels or spool stands, which is so constructed as to substantially' eliminate the possibility or chattering, caused by play at both'ends of the spool. The loose sleeve can be readily and cheaply applied to any spindle, and is adapted to lit snugly into the opening in any spool which is still serviceable, without requiringlv any adjustment of parts whatsoever; consequently creels or spool stands equipped with spindles embodying my invention will operate without vibration.

While I have shown my invention as being applied to a particular type of cree] ment along said'spindle in one direction by said shoulder and in the other direction by said nut.

2. ln a creel, a spindle having a reduced seat, a portion of which is threaded, and a frusto conical sleeve surrounding` the unthreaded portion or' said seat and maintained thereon by a nut coacting with the threadedV portion.

3. In a c-reel, a spindle provided with a reduced portion, said reduced portion having a shoulder, a frusto conica-l member rotatably 'mounted on said reduced portion, and means to hold said 'frusto conical member against said 'shoulder so as to positively position it longitudinally on said spindle.

Dated this 25th day ol April, 1923.
