TAKE-UP MECHANISM FOR LOOlVlS.

SPECIFICATION forming part of Letters Patent No. 638,937, dated December 12, 1899.

Application i'iled May 4, 1899. Serial No. '715,509- (No model.)

To all whom t may concern.-

Be it known that I, OSCAR L. OWEN, of Whitinsville, in the county of Worcester and State of l\Iassachusetts,`have invented a certain new and useful Improvem it in Take- Up Mechanism for Looms; and I hereby declare that the following is a full, clear, and ez;- act description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvement in the mechanism for taking up the cloth as it is woven' and Winding it on the l cloth-roll.

In weavingit is desirable that the attendant approach the front of the loom as closely as possible to secure a good view of the condition of the warp and of the cloth as it is woven. It is therefore desirable to place the sand-roll and the cloth-roll as much as possible uuder the breast-beam. To secure the close winding of the cloth and the proper stretch of the saine over the breast-beam, the cloth-roll should be held to the sand-roll with a rm pressure, gradually increasing with the diameter of the cloth-roll. i

The obj ect of my present invention is to secure these results.

The invention consists in the peculiar and novel construction and combination of parts by which the sand-roll and the cloth-roll are supported below the breast beam `and the cloth-roll is pressed against the sand-roll by the torsional resistance of a coiled spring, as will be more fully set forth hereinafter.

Figure l is a front view of a loom, the central portion being broken out to more clearly show, on a larger scale, the operative parts of the mechanism, the cloth-roll being shown in the position when the cloth is wound on the same, as indicated in broken lines. Fig. 2 is a vertical sectional view of the front part of a loom, showing my improved take -up mechanism. Fig. 3 is a skeleton view showing one end of the cloth-roll and the wormdetaching mechanism. Fig. 4 is a skeleton View showing the lower part of the worin-detaching mechanism. Fig. 5 is a skeleton view showing the strap connection between the cloth-roll and the torsion-shaft by which the cloth-roll is held against the sand-roll.

Similar marks of reference indicate correspending parts in all the figures. l

In the drawings, A A indicate the side frames of the loom; B, the breast-beam; C, the girth connecting the side frames; D D, standards extending from the girth C to the breast-beam B; E E, guideways in the standards D D; F, the sand-roll, and G G gearing for operating the sand-roll. These gearings G G indicate the usual mechanism for operating the sand-roll by which intermittent motion is transmitted, usually from the lay-swords, to the shaft of the sand-roll. H is the clothroll.

The sand-roll Fis journaled at its opposite ends in the standards D. Below the shaft of the sand-roll two collars 7L are supported on two studs 7L', projecting inwardly from and secured to the standards D. The straps h2 h2 extend over the collars 7i, 71 one endof the straps formingloops ha, surrounding the collars Mh", in which the ends of the shaft on the cloth -roll are supported and extend beyond the collars 7t4into`the guideways E. The other ends of the straps h2 are secured to the disks h5 h5, and these disks are secured to the torsion-shaft h6, supported in bearings near the lower end of thevstandards'D D. The coiled spring hl surrounds the torsion-shaft h6 one end of the coiled s rinfrbeinfsecuredV in the collar hs, which is secured to and turns with the torsion-shaft h6. The other end of the coiled spring hl is secured tothe sleeve hg, loose on the torsion-shaft h6 and provided with locking-notches. One end of the sleeve hi bears against the bracket hw, through which the shaft 7L extends, and which bracket is sei cured' to the girth C. The pawl 7L is pivoted on the bracket hw and engages with the notches on the sleeve 71,9, so that the tension of the coiled spring 71,7 may be adj ustedand act to rotate the torsion-shaft h6. The wormwheel il is secured to the end of the torsionshai't h6. The Worm t" is journaled in the bracket t2, pivotally connected by the stud 3 with one of the standards D. The worm c" is provided with the hand-wheel 4 or a similar device for turning the worm. The portion of the bracket i2 forming the journalbearing for the worm z" is provided with the cam-pawl 5. The bracket i2, with the worm ICO , and the hand-Wheel 4 may be swung into engagement With the Worm-Wheel or allowed to drop out of engagement with the same. l/Vhen engaged, the can1pawl 5 rests on the shoulder of the bell-crank lever 6 and is supported by the coiled spring 7, one end of which is secured to the bell-crank and the other end to the standard D. The rod S connects the bell-crank lever with the pawl 9, pivotally secured to the standard D, so that the pawl enters the guideWay E.

Then a cloth-roll is to beinserted, the collars h4 are placed over the shaft of the clothroll H. The projecting ends of the shaft are then passed into the openingsec of the guideways E. The Worm c is now turned to operate the worm Wheel and by it the torsionshaft h6 and with the same the disks 77,5, so as to wind up the straps 77,2 and raise the clothroll nearly up to the sand-roll. The end of the cloth is now passed around the cloth-roll H, and by again turning the worin the clothroll is forced against the sand-roll and one end of the shaft of the cloth-roll comes in contact with the pawl 9, moving the pawl outward and disengaging the hook of the bell-crank lever Strom the cam-pawl 5, which allows the bracket 2, carrying the Worm, to drop out ot' engagement With the worm. The loom being now running operates through the gears G G or a similar driving mechanism and the sand-roll F and, continuing to weave the cloth, winds the same, by the surface contact of the sand-roll with the cloth, onto the cloth-roll. The coiled spring 717 on the torsion-shaft 7LG acts, through the disks h5 and the straps h2, to hold the cloth-roll against the sand-roll until the desired cut of cloth is completed,

^ when the cloth-roll, with the cloth, is removed and another cloth-roll substituted. By this construction the front of the loom can be readily approached by the attendant, the sand-roll and the cloth-roll projecting but little beyond the front of the breast-beam. The adjustment of the coiled spring can be at all times readily made to secure the proper pressure of the cloth-roll against the sand-roll, as all the parts are in plain sight and readily accessible.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a loom, the combination with the sandroll and mechanism for operating the same, of the guideways E E below the sand-roll and forming the paths for the shaft of the clothroll, the cloth-roll H, the collars h4 on the cloth-roll, the collars 7L h supported on studs below the shaft of the sand-roll, the torsionshaft 7L, the coiled spring 71.7, means for adjusting the tension of the coiled spring, the disks h5 h5 secured to the torsion-shaft h6, the straps h2 712 connected with the disks h5 715 and formed at the opposite end with the loops h3 h3 supporting the collars h4 71,4 on the sha-ft of the cloth-roll H, the Worin-wheel on the torsion-shaft h6, the bracket 2 pivotally supported on one of the standards D, the Worm journaled in the bracket 2, the hand-Wheel 4 secured to the worm, the earn-pawl 5 on the bracket 2, the bell-crank lever 6, the coiled spring T supporting the bell-crank lever, the rod s connecting the bell-crank lever at the lower part of the loom with the pawl 'L'9 on the upper part of the loom, and the pawl 9 extending into the upper end of the guideway E; whereby the cloth-roll is supported by straps connected with the torsional, springcontrolled shaft andwhen raised into position by the worm and wornbwheel, automatically disconnects the worm from the Wormwheel so that the sand-roll may operate the cloth-roll' when the loom is started, as described.

In Witness whereof l have hereunto set my hand.
