TAKE-UP FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 704,314, dated July 8, 1902. t

Application filed October 1,1901. Serial No. 77,188. (No model.)

T0 all 1071/0111, it may concern.-

Be it known that l, FREDERICK C. GERFIN, of Columbia, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Take- Ups for Looms; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in takeup mechanisms for looms; and its object is to provide a very simple compensating device which can be readily attached to the takeup mechanisms of various kinds of looms without requiring any expensive alterations therein or additions thereto and which will hold the completed fabric securely against the warp tension and prevent annoying slipping of the fabric and dispense with the cumbersome contrivances commonly employed to actuate and hold the take-up roll. The tension on the warp-threads of the fabric tends to pull the fabric back from the take-up mechanism and is a great source of annoyance to the weavers, and many efforts have been made to prevent this. Another annoyance arises when the diameter of the take-up roll is increased by the fabric wound thereon, as then the latter roll will pull the fabric faster than the outfeed-roll will deliver it. To overcome this latter defect, frictiondrives have been made; but these have been generally cumbersome and ill adapted to various makes of looms and expensive in application.

My present invention provides a very simple but effective device whereby the take-up roll is frictionally driven from the outfeedroll and the friction devices can be adjusted at any time without stopping the loom.

The invention is particularly applicable to the Mason and Swivel looms, but is useful with other makes of looms.

The invention consists in the simple novel devices for driving the take-up roll from the outfeed-roll, as hereinafter claimed, and the accompanying drawings illustrate the same as applied to the take-up mechanism of a Mason loom.

In the accompanying drawings, Figure lis a detail vertical section through the take-up mechanism of a loom. Fig. 2 is a detail side elevation thereof. Fig. 3 is an enlarged longitudinal section through the adjustable friction device on the take-np. roller.

In said drawings, A designates the guide- 'roller, over which the Woven fabric W is led from the loom proper, (not shown,) thence to the outfeed-roll B, which is generally 6o rough-surfaced, and is rotated by a ratchet or other step-by-step motion, (not shown,) just as is usual in such looms. From roll B the fabric is led over another guide C and thence to the take-up roll D, on which it is wound.

On one end of the shaft CZ of the take-up roll D is loosely mounted a pinion or gear E, which abuts against a collar d on the rollshaft. This pinion is preferably provided 7o with an annular flange e, Within which itsa disk F, Whose inner face is provided with a leather or other suitable frictional surface f, adapted to contact with the face of Wheel E within the annulus c. Disk F is supported on a hub F', which is slidably mounted on the shaft dexterior to pinion E, but is keyed to the shaft, so that it cannot rotate thereon.

As shown, a pin d2 is tapped into the shaft and engages a keyway or slot f in the hub. 8o A coiled spring G is interposed between the pinion E and disk F and acts to force them apart, said spring being concealed within annular recesses @2]"2 of the pinion and disk, as shown. The separation or contact of the 8 5 disk and pinion is controlled by a hand-nut H, which is tapped on the threaded outer end d3 of shaft d, as shown, and by turning this hand-nut one way the disk can be positively forced toward the pinion, and by turn- 9o ing the hand-nut in the opposite direction the spring G is permitted to separate the disk and pinion.

The pinion E is driven from the outfeedroll B by any suitable means; but I prefer to use a train of gears, as shown, to wit: a pinion B on the outfeed-roll and an intermediate pinion B2 meshing with both pinions B' and E, thus communicating motion positively from roll B to pinion E. From pinion E the roe motion is communicated more or less powerfully to roll D through the friction-disk F, which in operation is adjusted so as to cause roll D to positively take up all the fabric fed forward by the outfeed-roll B, but will slip or yield if the tension on the fabric becomes too great between rolls B D, and thus automatically compensate for the enlarging diameter of the take-up roll as the fabric is wound thereon, while at the same time holding the take up roll securely against the backward pull of the Warp tension.

Pinion B2 may be journaled on a stud b, tapped through the adjoining standard S of the frame in which the rolls are journaled, and secured by a nut b on its inner end, as shown.

In applying this device to Mason looms it is only necessary to thread the end of the take-up roll shaft and attach the collar CZ and pin cl2 thereto. Then the parts E F G H can be readily placed on the shaft d. A hole can be tapped through standard S at the proper point and stud b fastened thereto and the pinions B B2 placed iu position.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

The herein-described frictional take-up for looms comprising a take-up roll having a projecting shaft threaded at its end, a collar ixed on the shaft, a pinion rotatably mounted on the end of said shaft between the collar and the threaded portion thereof, a frictional disk slidably mounted on the shaft exterior to the pinion but rotatable with the shaft, a hand-operated nut screwed on the threaded end of said shaft exterior to and engaging the hub of the disk, and a separating-spring placed on the shaft between the disk and pin` ion, said spring being confined in a recess in the disk; with the outfeed-roll, and gearing for driving said pinion from said outfeed-roll, substantiallyas and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

FREDERICK C. GERFIN.
