IMPROVEMENT IN FRICTION MECHANISMS FOR YARN-BEAMS.
Specification forming part of Letters Patent No. 139,236, dated May 27, 1873 application filed April 30, 1873.
To all whom it may concern:
Be it known that I, HELIM UHILsoN, of Ware, of the county of Hampshire and State of Massachusetts, have invented a new and useful Loom Yarn-Beam Friction Apparatus, and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing, of
. Which- Fig. 1 is a side elevation; Fig. 2, a top view, and Fig. 3, a longitudinal section of it as applied to the friction-head or wheel of a yarnbeam.
It consists mainly of a brake, a band, and a lever, constructed, combined, and arranged together and with the friction-wheel, substantially in manner as hereinafter described, and y as represented in the drawing.
In such drawing, A denotes the yarn-beam head or friction-wheel, it being grooved on and around its periphery to receive the frictionband B, which extends partially around such periphery, and at one end is attached to a screw, U, or may be connected directly with ward each other the said parts, but as a means" of adjusting the friction-bandto the wheel and the lever F. The break which bears against the periphery of the wheel is furcated and hooks upon ears or fulcrums e e, projecting in opposite directions from a lever, F, arranged and formed as represented. This lever is also forked at its upper part, and has a pin, g, extending l from one to the other of the prongs of the fork, the upper end of the friction-band being o fixed to such pin.
The band B I usually make of steel, with a lining, h, of leather or other suitable material@ xed to it on its inner side. A metallic loop, t', pivoted to the band serves, when slipped over the longer arm of the lever, to hold dowi such arm.
4By raising upward the said arm of the leve r the pressure ot' the friction-brake and baud 1 upon the wheel may be suddenly relieved, so
as to admit of the ready forward or backward,
movement of the yarn-beam, the advantageof which will be apparent to weavers. It alsoA ai'ords a means of regulating tho amount ot' friction, or of increasing or diminishing it, on the wheel, as circumstances may require.
I claim as my invention as follows, viz:
1. The combination of the brake D, the lever F, and the friction-band B, arranged as set forth.
2. The combination of the screw C and nuts b c, the brake D, the lever F, and the frictionband B, arranged as represented. 4
3. The combination ot' the clamp-jaw a E,
the screw G, the nuts b c, the brake D, the" friction-band B, and the lever F, all beingaranged and applied together substantially in manner, and to operate with the `yarn-beam head or wheel A of a loom, as stated.
