PRINCE PRINCE-SMITH AND DAVID WATER-HOUSE, OF KEIGHLEY, ENGLAND.

FLIER.

Application filed December To all whom it may concern:

Be it known that we, Sir Pruner: Pnrnon SMITH, baronet, and DAVID VVArnni-iousn, both subjects of the King of Great Britain, residing at Keighley, in the county of Yorkshire, England, have invented certain new and useful Improvements in Fliers, of which the following is a specification.

This invention relates to flier-spinning and analogous machines, and it refers especially to those machines wherein the fliers are carried by overhead supporting means and wherein the yarns or threads pass through nonrotatable parts before entering the spindles carrying the fliers; and the invention has for its object to secure greater uniformity in the yarn produced.

In these machines the. non-rotatable part through which the yarn or thread passes, usually known as the pot eye, is disposed concentrically with the hollow spindle supporting the flier, and in operation the length of yarn or thread between such poteye and the flier leg varies as the flier revolves which causes uneven tension on the yarn or thread and results in a non-uniform product.

The present invention is designed to counter-act this disadvantage, and accordingly in flier-spinning and analogous machines of the kind specified each pot eye is disposed eccentrically relatively to its corresponding flier spindle in such a manner that the length of yarn or thread between the pot eye and the flier leg does not vary as the flier revolves.

The invention is illustrated by way of example in the accompanying drawings in which Figure 1 is a vertical section of an overhead-supporting flier which, as is shown, is mounted by means of ball bearings cooperating with a. sleeve that is carried by an overhead rail and is located between the whorl and the flier spindle.

Figure 2 is a section through the fliersupporting rail and illustrates the path of the yarn or thread when the pot eye is eccentric to the spindle.

1 is the flier which is screwed or otherwise suitably secured to the spindle 2 that has an upwardly tubular extension 3 integral with which there is an annular flange i to which the whorl 5 is screwed and locked by means of one or more grub-screws 6.

The upward tubular extension 3 projects into a sleeve 7 which is fitted into a corresponding aperture in the overhead rail 8 Serial No. 605,599.

and is formed externally with an annular rib 9 above and below which are machined seatings for two ball-bearings l0 and 11 that are accommodated between said sleeve 7 and the whorl 5 and are supported in a vertical direction by said rib 9.

12 is a distance piece provided with a tommy-hole 13 and with a pin 14, which fits into a. slot in the sleeve 7.

15 is a cap which is screwed into the upper end of the sleeve 7 or is otherwise nonrotatably mounted above the flier spindle and is formed with an aperture 16 into which is fitted a porcelain or other pot eye 17 of which the bore is preferably of truncated conical form or is flared towards its lower end.

In the construction illustrated, the parts are secured by screwing the cap 15 into the upper end of sleeve 7 which by means of rib 9 draws the distance piece 152 towards the rail; the distance piece being held by a toinmy and the pin 14 preventing rotation of the sleeve 7 while the cap 15 is being ad justed.

The aperture 16 is located in an eccentric position in the cap 15 in such a manner that when the cap 15 is screwed home in the sleeve 7 or is otherwise secured in place that point on the inner circumference of the porcelain pot ye 17 which is towards or nearest to the drawing rolls of the machine, or in other words that surface of the pot eye over which the yarn or thread passes, is located exactly in alignment with the axis of the upward tubular extension 3 of the spindle 2.

It will be understood that the cap 15 and the pot eye 17 are both stationary and that the result of this manner of locating the pot eye is to equalize, at all points in the revolution of the flier, the distance between the point where the thread bears on the inner circumference of the pot eye and the point where it takes on to the flier leg.

In Figure 2 the length of thread between the pot eye 17 and the leg of the flier 1 is constant as the flier rotates and therefore the tension on the yarn or thread is also constant, with the result that uniformity in the yarn or thread produced is secured.

What we claim is 1. In flier-spinning and analogous machines, a flier, supporting means therefor, said flier being mounted rotatably on said supporting means, a tubular neck extending from said flier, an aperture in said flier supporting means above said tubular ne-k, a stationary member located in aperture in. said supporting means, and an eccentrically disposed passage in said stationary member, for the purpose of guiding thread axially of said tubular neck.

2.1n flier-spinning and analogous machines, aflier, overhead supporting means therefor, said flier being mounted rotatably below said overhead supporting means, a tubular neck extending front said flier, means to drive said flier by said tubular neck, an aperture in said overhead supporting means above said tubular neck, a stationary member located in said aperture in said overhead supporting means, and an eccentrically disposed passage in said stationary member, for the purpose of guiding thread axially of said tubular neck.

3.111 iiiespinning and analogous niachines, a flier, a supporting rail therefor, said flier being mounted rotatahly below said supporting rail, tubular neck extend ing from said flier, means to drive said flier connected with said tubular neck, an aperture in said rail above said tubular nerk, a stationary memberlocated in said aperture in said rail, and an ecentrically disposed passage in said stationary menber, for the purpose of guiding thread anially of said tubular neck.

4. In flier-spinning and analogous chines, a flier, a supporting; rail therefor, said flier depending rotatably from said supporting; rail, a tubular neck extending; from said flier, a whorl to drive said flier by said tubular neck, an aperture in said supporting rail said aperture being co-aXial with said tubular neck, a stationarymember located in said aperture, and an eccentrically disposed thread passage in said stationary member, for the purpose of guiding thread axiallyof said tubular neck.

5. h ther-spinning and analogous, chines, a flier, a supporting rail therefor, said flier depending rotatably from said supporting rail, tubular neck extending from said flier sakl tubular neck having; a driving whorl. attached thereto, a ball bearhetween said 'ilier and said supporting rail, an aperture in said S1i ;j 301'tii1g rail said aperture above and io-axial with tubular neck, a sta lonary nember located in. said aperture, and an eccentrically dis; posed thread in said Wationirry member one all of said cccentr' disposed thr ad. passaige being located. in axial alignment with said tubular neck.

(i ln flier-spirnina and analogous niachines, a flier, a sup said flier depending; rotatably 'rrom said supportinp' all, a tubular neck xtending from said iiier said tubular noel driving whorl attached thereto, i all. beari carried by said supporting); rail intermo diately ou said tubular neck and said driving: whorl, an aperture in said supporting rail said aperture being above and ce axiai with said tubular neck, a cap stationarily locater. in. said; aperture, passagein said cap said passage being eccentrically disposed elatively said aperture, and an eye in orting rai theretor,
