JOHN \VALDRON, OF NEYV BRUNSWICK, NEW JERSEY.

MACHINE FOR WINDING PAPER AND OTHER FABRICS.

SPECIFICATION forming part of Letters Patent No. 363,024, dated May 1'7, 1337- Application filed November 10, 1886. Serial No. filth 154.

To all whom it may concern.-

Be it known that I, JOHN \VALDRON, a citizen of the United States, residing at New Brunswick, in the State of New Jersey, have invented a new and useful Improvement in Machines for \Vinding Paper and Other Fabrics, of which the following is a spccifica tion.

This invention relates to machines for winding into rolls or reels, paper, cloth, textile or other fabric or material, and it is an improvement upon a certain machine for winding paper invented by me, and patented to me in and by United States Letters Patent No. 352,722, dated Nov. 16, 1885.

The machine upon which my present devices are improvements is one of a class the object of which is the automatic reeling or winding of fabrics into compact, smooth, and even rolls, which are free from folds or wrinkles.

Prior to the invention of the machine for which patent has, as stated, been obtained by me, smooth winding has been obtained by mounting the winding roll upon which the fabric is wound in a frame to which an oscillatory motion has been given in order to alternately lift and lower the ends ofsaid winding roll or impart to it a wabbling motion upon the driving roll upon which it rests and by which it is driven, all as fully set forth in United States Letters Patent No. 335,870, granted February 9, 1886, to Heinrich \Virr terwerber. Such machines as that of XVinterwerber, and also that for which I have made application for patent, obviate the difficulty which in the operation of winding material, such as paper, has heretofore been experienced in keeping the material smooth and true as it is wound, and in preventing the formation of wrinkles, folds, and other irregularities, which affect the market value of the finished and wound product, and in many instances, especiallyin those of decorated wall papers, tend to destroy the fabric itself, because, in the case of grounded or coated papers, in which the color or paint is applied to only one side but is apt to leak around beneath the edges, the paint or color beneath the edges thickens the paper at its edges and consequently makes the roll of paper thicker or of greater bulk at its edges than atits central and other portions,

(No model.)

with the result that the central portions have, as stated, become wrinkled, creased, folded, and indented, while the edges under the tension have in many instances burst.

My present improvements relate especially to devices for putting the paper or other fabric to be wound under, and retaining it at, predetermined tension, the tension being applied in advance of the passage of the material to the Winding roll.

A machine embodying my improvements is represented in the accompanying drawings and described in this specification, the particular subject matter claimed as novel being hereinafter definitely specified.

In the drawings, Figure 1 is a side elevational view of a machine embodying my improvements. Fig. 2 is a front elevation of said machine; Fi 3 is a fragmentary front elevational detail of one of the guideways for one of the carrying arms of the winding roll; Fig. 4 a fragmentary perspective detail of the adjustable tension rolls,with the construction and application of which my present im provements are concerned, and Fig. 5 a view in perspective of a modified form of a driving roll adapted to be employed in the machine to which my present improvements are applied.

Similar letters of reference indicate corre sponding parts.

In order to a more thorough comprehension of my present improvements it is essential to explain the machine which forms the subject matter of my patent above referred to, and to which machine my improvements are preferably applied, although the improvemcnts, as such, are applicable to other forms of machine.

In the drawings*A, A, are the side frames of the machine, which are conveniently mounted upon a bed plate A which, if desired, are tied together by suitable tie bars, and which together with the bed plate constitute the framework of the machine. The fabric B assumed to be wall papcr-is led into the machine preferably over fixed streteheabars a housed in a supplemental frame work a surmounted upon the side framcs, and is conducted around against a fixed tension roll, which I term the upper tension-roll O, of any preferred character, housed in the boxings 0 applied to the side frames, then around ings d in the frame work, and from the guide roll the paper is led over the driving roll F, housed, in parallelism with the guideroll, in boxingsf and attached to the winding roll E, the gudgeons e of which are entered in adjustable bearings e respectively mounted upon two carrying arms G, independently pivoted at their inner ends, at g, to the frame work, travelling in ways 9 supported from the frame, and at their outer ends provided with counter weights H, conveniently applied in any desired series upon weight hangers g pivotallyconnected with said carrying arms.

One of the gudgeons of the driving roll is prolonged beyond its boxing and provided with driving pulleys P, or equivalent devices, through which rotation is imparted to said driving roll.

The frame work as an entirety, its stretcher bars, guide roll, and winding roll proper, that is apart from its mounting, are all of a general character common in these machines.

The driving roll F is of a special construc tion and its application in the machine in combination with the winding roll and other rolls constitutes the invention for which I have received a patent as stated. This driving roll F is, as shown in Figs. 1 and 2, pro vided with a series of alternately disposed vanishing grooves f, being tapering gutters, notches, corrugations, indentations, or channels, formed longitudinally upon the surface of the roll, in alternated or staggered disposition, and which have their greatest depth upon the edge of the roll and taper or gradually lessen to a point near or beyond the center, where they Vanish. Their office is, in the rotation of the driving-roll, to present such inclined surfaces as to occasion a tilting, rocking, .or rise and fall of the alternate ends, or wabbling, so to speak, of the winding roll E and its wound fabric B, upon the surface of the driving roll. Instead of employing grooves or gutters, the same result can be obtained by providing tapering ridges, f, Fig. 5, upon the surface of the roll.

beyond said side frames provided with spur wheels Q, fixed on them.

R is an adjustable shaft horizontally disposed in parallelism and in the same horizontal plane with the yoke shafts. It is supportedin boxings r applied to the side frames, and passes completely across the machine from side frame to side frame. Its extremities which project beyond said frames are provided with fixed pinions S which mesh with the spur wheels Q. One extremity of this shaft is projected beyond the pinion to carry a fixed ratchet wheel T provided with a handle it, the teeth of which wheel are in engagement with the gravity or other pawl U pivoted to one of the side frames ofthe machine.

The pivoted yokes which carry the adj ustable tension-rolls, being parallel, move in unison upon their shafts upon rotation being imparted to the spur wheels which said shafts carry. This rotation is imparted to said spur wheels through the pinions upon the adjusting shaft, by the rotation of said shaft as oocasioned by the movement of the handle-provided ratchet wheel, so that any preferred adj ustment of the yokes and their tension rolls y can be readily secured,-retention of the yokes and rolls in their adjusted position being effected by the action of the pawl in looking the ratchet wheeliupon the adjusting shaft.

In the drawings the adjusting rolls are represented in full lines in a given adjusted position. In Fig. 1, however, a different adjustment is represented in dotted lines. The adjustment of the yokes and rolls can of course be effected by applying but one spur wheel. I prefer, however, to employ two such wheels in order to equally distribute the power upon both yokes.

It would of course be possible to apply the handle directly to asingle applied spur wheel and employa pawl operating in conjunction with such wheel, which would then become a of the spur wheels and pinions may, of course,

be varied to enable me to more or less rapidly adjust the tension rolls.

Such being a description of my improve ments their operation, as well as that of the machine to which they are shown applied, will be sufficiently understood. Suffice it to repeat that the paper or other fabric to be wound, having been introduced through all of the tension rolls and carried over the guide roll to the winding roll, is, after being put under the desired tension by the adjustment of the adjustable tension rolls, smoothly and evenly wound upon the winding roll, the vanishing grooves serving to impart to said winding roll an oscillatory movement, which the independently acting carrying arms permit, and which imparts to the wound fabric a smoothness otherwise difficult to obtain. The joggling motion has also the tendency to throw the edges of the fabric a little out of line, and

thereby prevent the thickening of the wound roll at its ends to an extent greater than its thickness at the middle.

Having thus described my invention, I claim:

1. The combination of a driving roll provided with vanishing grooves, a winding roll, upon which fabric is wound, surmounted upon said driving roll and adapted to be rotated by it, means for rotating said driving roll, adj ustable tension rolls for regulating the tension of the fabric upon the winding roll, and means for adjusting the adjustable tension rolls, substantially as set forth.

2. The combination of a driving roll provided with vanishing grooves, a winding roll, upon which the fabric is wound, surmounted upon said driving roll and adapted to be rotated by it, means for rotating said driving roll, fixed tension rolls, adjustable tension rolls for regulating the tension of the fabric upon the winding roll, and means for adjusting the adjustable tension rolls, substantially as set forth.

3. The combination, in a paper winding machine, of a driving roll having vanishing grooves, a winding roll upon which material is wound and which is supported upon and rotated by said driving roll, independently moving bearings for said winding roll, adjustable tension rolls for regulating the tension of the fabric upon the winding roll, and means for adjusting the adj ustable tension rolls, substantially as set forth.

4. In a paper winding machine, the combination of the driving roll provided with vanishing grooves, awinding roll, upon which the fabric is wound, surmounted upon and driven by said driving roll, boXings for said winding roll, carrying arms upon which said boxings are mounted, adjustable tension rolls for regulating the tension of the fabric upon the wind ing roll, and means for adjusting the adjustable tension rolls, substantially as set forth.

5. In a paper winding machine, the combination of the driving roll provided with vanishing grooves, a winding roll, upon which the fabric is wound, surmounted upon and driven by said driving roll, boXings for said winding roll, carrying arms upon which said boxings are mounted, fixed tension regulating rolls, adjustable tension rolls for regulating the tension of the fabric upon the winding rolls, and means for adjusting the adjustable tension rolls, substantially as set forth.

In testimony whereof I have hereunto signed my name this Fourth day of November A. 1)., 1886 JNO VVALDRON
