I No. 827,130.

Application filed December 6, 901. newsl tter-28, 11 905."-serieiita'zgatvef To all whom it may concern: f v Be it known that I, SIMON W. WARDWELL,

a citizen of the United States, residinggat Providence, in the county of Providence and State ofRhode-Island, have invented anew and usefulTake-Up for Looms, of which the following is a specification. My invention relates to take-up devices for looms, and especially for narrow-ware or webbing looms, which produce tapes, ribbons, and similar .narrow fabrics. p

The object of my invention is toproduce a device for winding the fabric on the m as fast as it is woven in a compact self-sustaining' package without rolling, twisting, 'or

otherwise defacing or impairing the quality of the fabric. e

The form of. structure employed and the manner of its application to the loom and of its operation are fully described in the following specification and illustrated. in the a ccompanying drawings, of which F'gure 1 is aQfront view of aportion of a loom, showing my improved take-up attachment and its relation to the loommechanism.

is restrained and limited by the rate of delivery, of the tape, so that the cam rotates within the sleeve L, causing the roll 0 to travel in its groove. The pressure against the rollis from that side of the groove to which the tongue of the switch is swung, as shown by the full lines in Fig. 6. With the switch in the position indicated in this figure its spreading head extends across the portion Z of the groove, and as the cam rotates the roll 0 makes contact with the head p of the switch and, swinging it on its pivot, throws it into the position indicated by the dotted The roll 0 travels along the portion Z of the groove to the end of its traverse, when it enters the reverse portion Z of the groove and travels back to the crossing at, i where the switch P again guides it along its which extends the length of the sleeve.

proper course and having passed the crossing it again engages the head p of the switch to throw it back into the position indicated by the full lines of Fig. 6, ready toagain guide the roll 0 alon the portion Z of the groove and prevent its eing diverted therefrom into the portion Z of the groove at the crossing at.

In the periphery of the sleeve M is cut a longitudinal groove or narrow depression, preferably of the form indicated in Fig. 5,

EX- tending longitudinally across this depression is a spring R, secured to the sleeve M by the pins 1" 1", and at a point intermediate the ends ofthe spring is a projection 1', made by suitably. forming the spring. This spring serves to secure detachably to the sleeve M the tube N, on which the tape is wound. The tube N is made of wood-or other material with an internal annulargroove n intermediate its ends, corresponding in position with the proj ection r on the spring B. At suitable intervals in the groove there are projections, as indicated in Figs. 3, 4, and 5 by the pins n.

;The projection 1' of the spring R engages the groove n to prevent the tube from moving longitudinally on its sleeve and also engages one of the pins n to drive the tube rotatively.

- each section must The winding-shaft B, on which the tubecarrier is mounted, is -made in several sections, suitably coupled together to be rotated as one. shaft, but with each section removable, so that the completed packages may be readily removed. Each section supports a plurality ofthe tube-carriers, so that, to prepare the winding-shaft for winding, the tubes to be mounted on the mid-portion of be passed over the tubecarriers near the ends, and, likewise when the winding of the packages is completed the latter must be removed in the same manner. This is readily accomplished, as the spring R,

i while strong enough to retain the tube N in place during the winding, is not so strong as to preventv the passage of the tubes for application or for removal.

- To properly deposit the tape in position on livery of the ta the surface of the package,it is essential that the guide, whereby it is laid, bear at all times against said surface. The guide in question is a rod j, having a groove j, through which the tape is guided and which prevents it from lateral movement during the winding. The extended portions of the rod on either side of the groove serve to press and hold fiat the tape already wound. This rod or guide j is mounted in the end of an arm k, which in turn is mounted on the rod K to rock thereon so that the guide may be pressed at all times against the surface of the package and swing with the increasing diameter of the package. That the guide and its arm may be as compact as possible, the guide is so set into the side of the arm that the latter does not fully surround it, so that the guide may bear with its full length upon the package. The arm is is restrained from movement along the rod K by the hub 762 of an arm 7c, the extremity of which is formed as a guide j, under which the tape passes before it reaches the guide The 'uide is made adjustable about the shaft K and is to be located in such relation to the guide that the latter is maintained in contact with the surface of the package by the tension of the tape passing from the guide 1' over an intermediate guide 7' and under the guide The operation of my improved device is as follows: The tape passes from the shuttle or weaving mechanism at S, over the guide-roll i and under the guide-wheel i, to the sand-roll C, which rotates in the direction indicated by its arrow, Fig. 2. Drawn by its adhesion to the sandpaper surface of the roll C the tape is delivered under the guide j, over the guide j at the extremity of the arm 71?, and under the guide j to the tube-carrier. The shaft B is driven at a speed which insures a reciprocating movement of the package at its smallest diameter, or, in other words, at a speed such that were the tube on which the tape is wound rigidly secured. to its shaft the rate of surface speed of the tube or of the package IIC would materially exceed the linear speed 01 a the tape as delivered from the weaving. As the tube is not thus rigidly attached, but can slip with its carrier on its cam, its movement of rotation is retarded and limited by the dee, and hence it has a combined motion 0 rotation and reciprocation, and as the guide remains stationary the tape is laid in openly-coiled helices, forn'ling a self-sustaining package in which the number of turns made by the tape in the length of the package gradually decreases with its increasing diameter. That this is the case is due to the gradually-changing speed relation between the cam L and the package wound on the tube N, due to uniform lineal rate of delivery of tape and to gradual increase of diameter of the package. When the winding is first commenced, there is the least amount of slip between the cam L and the sleeve M. Hence at this'stage of the winding thetwo rotate most nearly at the same speed, and the sleeve reciprocates but slowly, making, for

instance, one traverse movement in one di- 'rectlon during two rotatlons.

I As the packageincre'ases .1n dlameter the sleeve rotates more slowly, and there is a greater difference 'in the relative speeds of rotation of the cam and sleeve, and consequently a more rapid movement of reciprocation of the sleeve M,

' r so that at one stage of the winding the pack age will make one traverse movement in one rotation and a half, then. in one rotation, and 5 guide which delivers the tape to the-winding.

VVh'cn the fabric was of material width and woven plain, little difficulty was experienced; but very narrow tapes, and especially those woven in pattern, form an unstable package,

which when -of material diameter breaks down, causing'the yarn to become tangled,

.twisted, and otherwise injured. Patterntapes are particularly difficult to wind, be-

cause thepattern-weave is more or less raised and the successive layers, placed directly one over the other, do not lie flat, and hence are more readily displaced. With my improv ed take-up the tape is maintained flat, so that creases and Wrinkles .are obviated. The

package produced is self-sustaining, so that there are no kinks or snarls to be straightened out before the packing. I do not herein claim any of the features herein shown and also shown and claimed in my application for Letters Patent filed March 3, 1902, Serial No. 96,532. a Without limiting myself to the recise construction or arrangement shown, claim- '1.
