- WARP REGULATOR.

N0 189,775. Patented Apr'1117, 1877.

UNITED STATES PATENT OFFICE WILLIAM OOTHOUT, OF BROOKLYN, E. D., NEW YORK, ASSIGNOR TO HIMSELF AND GIBBONS L. KELTY, OF SAME PLACE.

IMPROVEMENT IN WARP-REGULATORS.

Specification forming part of Letters Patent No. 189,775., dated April 17, 1877 application tiled February 14,1877.

' which the, following is a specification In looms for weaving corded fabrics. such as terry, and piled fabrics, such as Brussels, Velvets, 860.,13116 surface-warp is drawn along more rapidly than the foundation-or back warps, and in so doing there is sometimes irregularity in'consequence of the varying tension or friction upon the yarn or yarnbeams; hence the corded surface is liable to slight irregularities, or a greater or less proportion of surface-warp in comparison to the.

foundation-warpis consumed. I

The object of the present invention is to insure entire uniformity in the surface-Warp relatively to the foundation or back warps and for this purpose I make use of two sets of regulator-rollers, one for the surface-warps, and the other for the back or foundation warps, and these are geared together in such a manner that the surface speed of one set of rollers will bear the same relation .to the surface speed of the other set of rollers that the surface-warps bear to the foundationor back warps, so that while the take-up operates in the usual way to draw along the fabric in the process of weaving, the warp-regulator willinsure uniformity in the supply of the different 'kinds of warps.

1n the drawing I have represented the improvement by a section transversely of the regulator-rollers.

The cloth beam a, breast beam b,1ay c, heddles d and their operative mechanisms are to be of any desired character, and operate in any of the well-known modes of weaving, and, hence, do not require further explanation.

The rollers f g h form the group of rollers that regulate the back or foundation warps 70.

These are geared together, and the warps pass around the same in the manner indicated, so that they move together, and the movement 'of the surface of the rollers determines the speed of the warps.

I am aware that one group of rollers of this character has been employed to regulate the whole of the warps in the loom.

The rollers l m n, form a second group of warp-regulating rollers for the surface-warps 8. These rollers are geared together, so that they move with the warps, and at the same surface speed.

' I have shown the gears 0 upon the rollersf, g, and h larger than the gears 4' upon the rollers l m 'n, so that the gears can all form one I train, and the respective groups of rollers will move at the relative speed resulting from the difference in the size of the gears. It may sometimes be preferable to have the rollers of each group geared together, and to have changeable gears upon the projecting shafts of one roller in each group to connect the groups, so that these gears can be varied to proportion the surface speed of the respective groups of rollers according to the relative speed with which the surface and foundation warps are required for the weaving.

I claim as myinvention- In a warp-regulator, the combination of two groups of rollers, one for the surface-warps, and the other for the foundation or back warps, and differential gearing for connecting the rollers and determining the relative speeds of movement of the warps, substantially as set forth.

Signed by me this 8th day of February, A. D. 1877.

WILLIAM OO'IHOUT.
