MACHINE non BEAMING YARNS.

Application filed September 2, 1921.

To all whom it may concern Be it known that we, RICHARD ANDER'roN and JOHN CALVERT BLAOKHURST, sub ects of the King of Great Britain, and residents,

respectively, of 33 Elswick Avenue, Deane Bolton, in the county of Lancaster, England, and 8 Yarrow Road, Chorley, in the county of Lancaster, England, have invented a certain new and useful Improvement in or Belating to Machines for Beaming Yarns, of which the following description, having reference to the accompanying sheets of drawings, is a specification.

Our invention relates to improvements in or appertaining to beaming machines. As is well known in these machines the beam during winding is pressed into frictional contact with a cylinder or drum, the flanges of said beam overhanging the outer edges of said cylinden, It is not desirable that the latter should rotate in contact with said flanges owing to the large amount of friction which would be engendered thereby, and becausesaid flanges are often of irregular formation, thus a slight distance is always allowed to intervene between the edges of said cylinder or drum and the inner surface of the beams flanges. For this reason the coils of yarn at the outer edges of said beam are not pressed to the same extent as are the remainder thereof, consequently the yarn wound on these parts is slacker than said remainder and in addition to this, by the side portions not being pressed upon to the same extent as the other parts of the beams, a greater length of yarn is wound on at these said side parts. These conditions when the beam isremoved and applied to a slashing or sizing frame for treatment therein, cause what are commonly known as slack sides to often occur in the unwinding of the yarns, which have the disadvantages well known. The object of our present invention is to ap ply means to beaming machines whereby the yarns are pressed to approximately the same extent close to the inner faces of the beams flanges as at the other parts of said beam, thus obviating the disadvantages referred to. The device which we employ consists of conical rollers which form additional pressing means and are mounted to press upon the beams at and near the edges thereof such rollers being so mounted in position that should they come in contact with the beams flanges they only do so practically at a point.

Serial No. 498,035.

Means are also employed to allow the rollers to recede as the beam increases in diameter and to prevent the return of said rollers from withintheir bearings when same are moved away from said beam for purposes herein after described. i

In order that our said invention may be readily understood, we have hereunto appended sheets of drawings illustrative thereof, to which by figures and letters, reference is made in the following description Fig.'1 is a sectional end'elevation of a sufficient portion of a beaming machine to illustrate the application thereto of our improvements.

Fig. 2 is a rear elevation parts illustrated by Fig. 1.

Fig. 3 is a sectional end elevation "of the bearings for the conical rollers hereinafter described. I

Fig. 4 is a plan ofsaid bearings.

Fig. 5 is a drawing inodetail of a portion of said bearings.

Fig. 6 is a diagram hereinafter referred to.

Similar letters and figures of reference indicate like parts throughout the several views. l

In the class of machines to which our invention relates, the beam of yarn A iscarried in bearings mounted upon the leversA so as to rest or be pressed intocontact with the drum B,-;said lever bearings allowing said beam of yarns A to rise as it increases in diameten The pressure between said beam A and the drum B causes said yarns to betightly wound on said bean The outer edge B of the drum B extends into proximity to the flanges A ofthe beam A, but not intdcontact therewith for the reasons above described, consequently the several layers of yarn intervening" between the edge B and the flange A are not so firmly pressed as are those in contact with the drum l3 hence we mount additional pressing means consisting of certain of the of conical rollers to press upon the yarns at in contact with or in close proximity to the flange A as they only touch said flange at a point or a surface of small extent. 'lhese conical rollers and their spindles are carried by hearings or supports Z) to which are connected racks c sitting and sliding within casings or bearings d, these latter being fixed to brackets or clamps e mounted upon the square shaft f. The latter has also fixed upon it the levers g carrying the treadle g which operates the usual clutch 7L orbeltshifting device through the slotted lever (fulcruined upon the shaft 13 and the usual vertically movable rod h, although it will be readily understood that the shaft upon which the supports or bearings for the conical rollers c are mounted may form part of any other type of clutch. operating or belt-shifting mechanism.

We prefer to mount our improved parts in connection with devices for governing the starting and stopping of the machine for the reason that when the machine is started into operation the conical rollers are pressed against the beam A, while when the motions of the machine are arrested, said rollers move away from said beam A somewhat as shown in dotted lines by Fig. 1 leaving the parts with which they normally make contact free from any pressure at this time.

The casings or bearings cl and racks 0 we form somewhat concentric with the drum B in order that when in their position out of contact with the beam A they will not interfere with the free vertical movements of the ordinary tension rollers of the machine. To allow the desired adjustment of the conical rollers a the spindles a thereof are or may be adjustable upon their brackets 7) which in turn are movable relatively to the racks a, while the casings (Z are adjustable vertically and laterally by the slots d formed in the projecting lip d and the slots 6- formed in the brackets e, which latter may also be adjusted in position along the shaft The extendin portions e of the brackets e are preferably formed to only partially surround the shaft 7' as this is in some cases mounted in close proximity to o the drum B.

Vithin the casings d and bearing against the ends of the racks c are springs m which tend to move said rack c from within said casings d, this movement being prevented by the springcatches 01. At the beginning of the winding of the yarns on the beam A, the ratchets n are moved by the attendant to liberate the racks c which are then forced out of the casings (l by the springs m to press the conical rollers a against the yarns on said beam A which will then be of small diameter, and as said diameter increases. the racks c are forced back within said casings (Z against the tension of said springs m and held in their positions therein by the ratchets n, such positions being varied throughout the winding of said beams A, thus at whatever part of the formation of said beams A the starting or stopping mechanism of the machine may be brought into operation, when the conical rollers are moved clear of the beams they will be held there by said ratchets a.

Such being the nature of our said invention, what we claim is 1. In a machine for beaming yarns, a beam, a longitudinally disposed drum rotating in connection therewith, conical rollers bearing against the surface of the beam in proximity to the edges thereof, and adjustable bearings carrying said conical rollers.

2. In a machine for beaming yarns, a beam, a drum longitudinally disposed relatively to said beam, conical rollers pressing upon the beam and yarns in proximity to the flanges of said beam, bearings for said conical rollers and spring pressure devices for retaining said rollers in contact with said yarn.

3. In a machine for beaming yarns, a beam, a drum longitudinally disposed rela tively to said beam, conical rollers pressing upon the beam and yarns in proximity to the flanges of said beam, bearings for said conical rollers, spring pressure devices for retaining said rollers in. contact with said yarn, and a device for holding said conical rollers in any position into which they may be moved.
