GUIDE MEANS FOR WARPEBS AND SIMILAR MACHINES.

Application filed May 21,

To all whom/2'25 may concern:

Be it'known that I, ALoNzo E. RHoAnEs, a citizen of the United States, and resident of Hopedale, county of Worcester, and. State of Massachusetts, have invented an 1111-. provement in Guide Means for Warpers and Similar Machines, of which .the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts. I

This invention relates to yarn winding machines wherein the yarn iswound upon a core in a cylindrical mass by means of a driven windingdrum mounted in parallelism with the core and acting by peripheral engagement with the yarn mass on the core to efiect the winding operation.

The invention in its preferred form is particularly designed for a warper wherein the yarn is wound upon a warp beam comprising a core, heads in the'form of disks at each end and journals, but it is equally applicable in its broader aspects to any form of yarn winding machine of this type wherein it is desired or necessary to maintain the longitudinal position of the yarn receiver in a relatively fixed position with respect to the frame and the winding drum.

The object of the invention is primarily to provide means in combination with the elements of the machine involved which act to prevent longitudinal movement of the yarn receiver relatively to the drum during the winding operation or; which act to maintain the yarn receiver during the winding operation in fixed longitudinalposition.

In this type of machine there is necessarily a relative bodily transverse movement between the core on which the yarn is wound and the winding drum in order to effect the winding operation and in the warper one of these elements, usually the beam, is journalled in arms hinged or movably secured to the frame so as to allow the beam to swing or move bodily transversely toward and from the drum. The winding drum usually comprises a relatively thin cylindrical iron shell open at the ends and if the longitudinal position of the beam is not maintained fixed the longitudinal movement of the beam due to the longitudinal shifting of its bearings or the yield of the supporting arms allows the ends of the shell of the winding drum to engage and grind against the heads 1923. Serial no. 640,430.

of the warp beam often injuring or damag ing the winding drum. Furthermore, this grinding action often so reduces the length of the winding drum as to preventthe proper pressure being applied to the ends of the cylindrical yarn mass wound on the beam. This is highly undesirable as it results in soft yarn at the ends of the mass and unequaltension-throughout the yarn mass.

With this invention the warp beam or other yarn receiver is accurately maintained in a fixed longitudinal position so that during the winding operation and during the transverse movement of the beam or yarn receiver there is no danger of they heads of the warp beam engaging the winding drum consequently the winding drum is uninjured and its length maintained. The pressure on the yarn mass is kept uniform throughout and accuracy in the placing of the yarn upon the beam or yarn receiver is insured.

, The present invention in its broader aspects is subsidiary to the invention set forth in my application filed concurrently herewith, Serial No. 640,429. In the present invention, in its preferred form, a follower and guide are provided, one secured to the.

movable element, usually the yarn receiver, and the other to the frame, and these co-operate to prevent the undesirable longitudinal movement during the relative transverse movement between the yarn receiver and wlnding drum.

These and other objects and features of the invention will more fully appear from the accompanying description and drawings and will be particularly pointed out in the claims. r

In thedrawings; Fig. 1 is a side elevation of a portion of an ordinary type of warper with only those a parts shown which are necessary for a disclosure of the present inventlon;

Fig. 2 is a plan view of the construction a cylindricalcore 3 on which the yarn mass.

iswound, journals t'projecting at'each end of the core, and generally flat or disk-shaped heads 5. These headson'tlie interior oppositely facing surfaces are flat and on the exterior surfacesare generally ribbed and braced as illustrated. The journals of the warp beam are usually mounted in bearings 6 formed in the ends of" arms.7 movably mounted on the frame. These arms allow the warp beam to movetransversely or swing toward and from the frame. The Warp beam is a very heavy structure as the heads are made of cast iron or steel and the heavy massof yarn wound thereon greatly increases the total weight supported in the journal bearings.

The winding drum usually comprises an iron cylinder Shaving a central shaft presenting thejournals9 mounted in bearings on the frame The drumshaft extends parallel to the beam shaft and'the drum is'rotated in the usual manner. The periphery of the drum rests against the yarn mass on the core of the-beam and thus acts to effect the winding operation, the beam swinging or moving transversely away from the drum as the operation proceeds. While the rela tive. transverse movement which takes place between the winding drum and the yarn receiver-isin the illustrated case secured by the transverse bodily movement of the yarn receiver, it will be understoodthat the present invention in its broader aspects is independent of the manner in which this transverse relative movement is secured. Furthermore, while'the yarn receiver is illus trated as a warp beam havingheads, the particular form of the yarn receiver is not im-' portant in the broader aspects of the invention.

In the preferred construction illustrated the fixed longitudinal position of the yarn receiver is secured, and thus longitudinal movement witlrrespect to the frame and the winding drum is prevented by a follower and guide construction. One of these elements is secured to the frame and the other forms a part of, or is secured to, the transversely movable element, which in the case illustrated is the warp beam. The follower and guide co-operate during the transverse movement of the movable element, such as the ivar'p beam, which occurs during-the winding operation, and insure that the longitudinal position of the movable element is maintained and consequently any relative longitudinal movement between that element and the frame and the co-operating element, such as the winding drum, is prevented.

In the preferred construction illustrated the'follower'is in-the formof a shoe secured to the journal of the warp beam and the guide is in the form of a track standing at right angles to the axis of the warp beam but curved on its face to co-Operate with the path of travel of the axis of the warp beamduring its transverse movement. 7

The guide-1O is in the form of a flat plate extending in a plane at right angles to the axis of the warpbeam and having its face 11 curved to correspond substantially to the path of movement of the axis of thewarp beam during the windin -operation. This plate 10 is secured to a socket 12 which in turn is rigidly secured by a set screw'13 to an arm or shaft 1% rigidly secured'by the set screw 15 in a socket 16 forming a part ofa bracket 17 bolted at 18 to the frame. This construction enables the position of the guide plate to be accurately adjusted.

The follower shoe, in the preferred construction illustrated, is mounted on'the warp beam journaled 4 and, as the follower coacts best with the guide when non-rotatable, this follower provides a construction by which it may still be mounted upon the rotatable journal 4: and yet not rotate with respect to the guide. A sleeve 19 is provided to fit over the journal 4 and this sleeve has at the outer end a comparatively large annular head 20, and at the inner end a com paratively small annular head 21. There is consequently presented between these annular heads an external annular recess on the sleeve. The sleeve is rigidly secured in proper position on the journal I by a set screw 22 threaded through the head- 20 and abutting the journal. The follower shoe is mounted in this recess and preferably comprises a shoe base 23 and a cap 24 having fiat co-operating surfaces and bolted together by the set screws 25. The line of division between the base and cap is diametrically of the journal 4, and these parts are constructed, when bolted together, to fit the annular recess in the sleeve 19 so that they may rotate with respect to the sleeve,-but;be prevented from longitudinal movement with respect to the sleeve by the annular heads 20 and 21. At their outer ends the shoe base and cap present an annular rim 26 concentric with but spaced from the sleeve head 20 thus providing an annular recess between the head 20 and the rim 26 to guard the set screw 22 which rotates with the journal of the warp beam. 7

The follower shoe. preferably on the base member 23, is p ovided with guiding lugs to fit and co-act with the guide 10. In the form shown the lugs 27, which are quite widely separated present surfaces which fit against and side upon the face 11 of the guide 10. Intermediate of the lugs 27 are a pair of lugs 28 spaced to form a recess 29 of the same width as the guide 10. These lugs 28 extend past the sides of the guide 10.

Thus it will be seen that longitudinal movement of the shoe, and consequently of the sleeve 20, and consequently of the warp beam, is prevented with respect to the guide 10, and consequently with respect to the frame and winding drum 8, at all positions of the warp beam. 7

The follower shoe is readily secured in place by slipping the sleeve 19 over the journal 4: andlocking up the set screw 22 at the proper point. The shape of the guide and the co-operating lugs on the shoe will depend of course on the path of travel of the movable element, such as the warp beam. The shoe and guide are adjusted so as to provide the proper positioning engagement therebetween without binding and slight play may be allowed so long as the positioning engagement is such as to prevent the beam heads from contacting with the winding drum during the winding operation. As the drum is rotated, the beam slowly swings or moves away from the drum and its longitudinal position is maintained with a minimum amount of friction.

It will thus beseen that the invention obviates the difi'iculties heretofore encountered and insures the accurate longitudinal position of the beam or yarn receiver with respect to the winding drum and the frame at all times.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:
