LOOM.

SPECIFICATION forming part of Letters Patent No. 555,705, dated March 3, 1896. Application filed September 24,1895. Serial No. 563,487. (No model.)

To Ml whom it may concern.-

Be it known that I, GEORGE F. I-IUTCHINS, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which the following is a specification.

My invention relates to narrow-ware looms, and more particularly to a take-up attachment for said looms, and the object of my invention is to provide a take-up attachment of simple construction and operation which will take up the goods as they are woven, and which is provided with a release device to release the woven fabric or cause it to become slack in case the operator wishes to pick out, 850.

My invention consists in certain novel features of construction of my take-up attachment, and more particularly of the release device, as will be hereinafter fully described and the nature thereof indicated by the claims.

Referring to the drawings, Figure 1 is a side view of my take-up attachment, looking in the direction of arrow at, Fig. 3, showing the breast-beam and friction-roll in section and the clamp-rolls closed or in the position they occupy when the take-up is in operation. Fig. 2 corresponds to Fig. 1, but shows the clamp-rolls opened to release the woven fabric; and Fig. 3 is a front view of the parts shown in Fig. 1, looking in the direction of arrow 5, Fig. 1.

In the accompanying drawings, 1 is the glass rod over which the woven narrow-ware fabric 2 is drawn.

3 is the breast-beam, to the under side of which the stands 4, carrying the take-up attachment, are bolted or secured.

The take-up attachment consists of the pair of hangers 5 and 6, which are preferably of substantially the shape and construction shown in the drawings. One of the hangers, as 5, is pivoted at its upper end in the stands 4 in the usual way. The other hanger, as 6, is pivotally supported by a pin 7 on the hanger 5, and the upper ends of said hanger 6 extend above its pivotal support and are con nected by spiral springs 8 with the upper part of the hanger 5 to draw said ends toward said hanger. The lower end of the hanger 6 carries a roll 9, which is adapted to bear against the fabric 2 on the under side of the take-up or friction roll 10 as said fabric passes under said friction-roll and over a roll 11 carried at the lower end of the hanger 5. Said roll 11 is adapted to bear on the fabric to hold it on the take-up or friction roll 10 in connection with the roll 9.

The friction-roll 10, fast on a central square shaft 10, is driven by gearing (not shown) in the usual way, and is provided with a sandpaper or other covering 10 to make a frictional contact between said roll and the woven fabric passing around the same. The springs 8 act to move the two clamp-rolls 9 and 11 toward each other to hold the woven fabric on the friction-roll.

I11 order to move apart the rolls 9 and 11 to release or slacken the fabric, I combine with one of the hangers, as 5, a cam-lever l2,which is pivoted on a pin 13 on said hanger. The cam portion 12 of said cam-lever 12, as said lever is raised, is adapted to engage the projecting end of a stud or pin 14, secured in the hanger 6 above its pivotal support. Said stud is preferably non-metallic to save oiling.

It will thus be seen that when it is desired to release or slacken the woven fabric to pick out, or for any other purpose, the operator simply raises the cam-lever 12, as shown in Fig. 2, which operates to move apart the lower ends of the hangers 5 and 6 carrying the rolls 9 and 11, as shown in Fig. 2.

It will be seen that the revolution of the friction-roll 10 in the direction indicated by the arrow, when the clamp-rolls 9 and 11 are in the position shown in Fig. 1, will cause the fabric 2 to be positively taken up, and if at any time it is desired to stop the take-up of the fabric or to slacken the same it is only necessary to move the cam-arm 12 to release the fabric from the friction-roll, as shown in Fig. 2.

When it is desired to bring the take-up into operation again, the free end of the fabric is drawn over the upper roll 11 to tighten the fabric around the friction-roll 10, and the cam-lever 12 is moved down into the position shown in Fig. l to allow the springs 8 to act to bring the rolls 9 and 11 toward each other to bear on the fabric.

- combination with a pair of hangers carrying rolls at their lower ends, and one of said hangers pivotally supported below the breastbeam, and the other of said hangers pivotally supported on the first-mentioned hanger, and springs for moving said hangers and rolls into operative position, of a eam-lever, pivotally supported on one hanger, and adapted to operate to move apart said hangers, and release the fabric, substantially as set forth.

2. lhe combination with a pair of hangers, each of said hangers carrying a roll at its lower end adapted to bear against the fabric passing around a friction or take-up roll, and one of said hangers pivoted on the other hanger, and a spring or springs for holding said rolls in engagement with the friction-ro1l, of a cam-lever or arm pivotally supported on one hanger, and adapted to engage a pin or 0 projection 011 the other hanger to move apart said hangers and release the fabric, substantially as set forth.
