CLOTH-WINDING MAcHINE.

Application filed April 2, 1925. Serial No. 20,106.

To all whom it may concern:

Be it known that I, CHARLES Gr. RICHARD- soN, a citizen of the United States, and resident of Springfield, in the county of VVindsor and State of Vermont, have invented certain new and useful Improvements in Clotl1-Winding Machines, of which the following is a specification.

This invention relates to the art of cloth winding, and particularly to the winding of commercial lengths of cloth or fabric upon a core-piece or winding board in order to package the cloth in the form of a flat bolt.

The cloth winding machines that are used for thus packaging the cloth into bolts are well known in the art and, therefore, need not be explained in detail. Essentially they comprise two oppositely aligned board-supporting heads or chucks which are rotated in unison to wind the cloth on the interposed winding board. As the cloth is kept under tension, during this winding operation, the core-board is subjected to considerable strain so that unless the board be of good quality and weight it is likely to buckle or break, in

either case producing imperfect packaging of the'cloth. It has been proposed to use a metal stiffening plate as a permanent'part of the winding machine to reinforce and support the core-board to prevent suchbuckling, but as the operator is-obliged to handle this stiffening plate a great many times a day, the excessive weight of thestiffening plates heretofore used has been a severe tax on the operator and has tended to slow up his work because of fatigue.

It is the object of the present invention to produce a stiffening element forcloth-winding machines of the type above referred to that shall afford a full adequate reinforcement for the thinnest and most flimsy coreboards used, while at the same time keeping the construction so light as to greatly lighten the labors of the winding-machine operator. A furtherobject of the invention is to afford full or complete support for the core-board and for the cloth that is being wound around the same.

To this end the invention comprises ahollow stiffening element of plano-convex cross section presenting a fiat face affording support for the core-board, and also affording complete support for the cloth being wound around the core-board so as to insure perfect winding free from wrinkling, while at the same time a very stiff and a very light construction is obtained. To further increase the stiffness, without materially adding to the weight of the reinforcing or stiffening element particularly in cases where windingboards are used for wide bolts, I interpose spacing devices between the two members of the stiffeningelement to prevent any possibility of collapse or buckling. These and other features of the invention will be particularly described in the following specification and will be defined in the claims hereto annexed.

In the accompanying drawings I have shown a simple, cheap and convenient em bodiment of the principles of this invention, in which: i

Figure 1 is a plan View of the stiffening element mounted in the opposed heads or chucks of a cloth-winding machine, the remainder of the machine being omitted. v

Figure 2 is a central longitudinal section of the stiffening element held in the opposed chucks.

' Figure 3 is a cross-sectional view of said stiffening board on an enlarged scale, showing the spacing devices or struts interiorly disposed therein.

The stiffening element here is shown applied to twoopposed rotary chucks of wellknown construction. One of said chucks is usually hinged to permit the downward or lateral swinging of the wound bolt of cloth after the opposite end has been dis-engaged from its sup ortin chuck.

The hinge chuc in this case, comprises a'trunnion sleeve 10 secured to a short stub shaft 9 by which it is rotated, and having on its opposite sides trunnions 10*, which form pivotal support for the forked clamping head which is made in the form of a'yoke whose two outwardly extending arms 12 arepivotally supported upon the trunnions 10 and whose body portion comprises transverse spaced jaws 12 between which is inserted the adjacent end portion of the stiffening element or truss 20, and are held in such inserted position by means of a cotter pin or equivalent device 13, which can be easily removed for inserting different sizes of stiffening elements. A spacing member 14 is secured in the hollow end portion of the truss 20 and is perforated or bored to receive the pivotal connecting pin 13 and thus serves also as a bearing member so as to avoid bringing the whole longitudinal stress of the truss upon the thin edges of the truss plates through which it is preferably inserted.

The oppositechuck comprises a head 16 with oppositely projecting wings or plates 16 and movable clamping jaws 17 which are clamped against the adj acent end portion of the inserted stiffening element by means of clamping nuts 17*.

The stiffening elementitself, accordingto the form illustrated in the drawings, comprises two sheet metal plates 21- and-22, one of which is flat presenting a plane surface affording full contact with the core-board 25 to reinforce or support every portion of it, while the opposed sheet metal plate 21 is transversely bored to form an exterior convex surface which, nevertheless, affords; complate contact and support, for the cloth passing around wrinkling. The two plates 21' and 22 are rigidly secured together along their sides or. longitudinal edges in any suitable manner, as by rivetin weldingor the like, so

that there is proc need a very stiff, light,-

hollow truss affordingfullsupport both for the cloth and for the core-board.

A spacing member 14 is inserted between the separated ends of this reinforcing ele ment to occupy the medial portion of the end attached to the hinged chuck. site end, that is the end that is releasedfrom the chuck to permit removal of the wound bolt,.the plate 21 is flattened to lie in parallelism with the adjacent end portion of the plate 22 so as'to reduce the thickness of the stiffening element atthe end from wliichthe cloth bolt :is removed, and also afford a proper shape for firm clamping engagement betweenthe jaws 16 and 17 of the releasing chuck, c

To further stiffen the structure I introduce along the medial line a series of short spacing devices or studs 23., particularly where the stiffening element is made of extra length for wide bolts.

In practice,the core-board or bolt-board is placed against the fiat face of the stiffen; ing element 20- so as to liebetween the; projecting ledges formed at each end by the jaw 12 and the jaws 17, and is held in place by simply wrapping the initial end of the cloth around the assembled core-board and stiffening element for one or'two turns, after which the machine is started in operation to complete the winding of the bolt. To remove the cloth-board'the clamping nuts 17? are released sufficiently to allow the stiffening element to be swung edgewise out from between the clampingjaws 16 and 17, which movement is permitted by means of the.

pivotal connection afforded by means of the pivot or fulcral pin 13, carried by the hinged chuck and passing through aligned aperthat face, thereby avoiding At the oppo-.

holding jaws 12 should snugly embrace the fulcral end of the stiffening member but not with sufficient grip orfriction to prevent the swinging of the. stiffening element to openposition to permit the removal of the cloth-bolt. I

It will, therefore, be seen that this truss element not only provides a full supporting surface in complete contact with the coreboard on one side and the cloth 'on the other side when a core-board is used, but it is also capable of forming the whole support or re-' enforcement for the cloth being Wound when it is desired to package the cloth Without any interior core-board.

What I claim is: p 7
