The connecnying drawings. tions of the cords with the brackets are also I My invention consistsofan adjustable ropeadjusted, owing to the openings P. By these bracket and an adjustable fulcrum for the' means the leverage on either width of the lever of a warp-tension of a loom, the same fabric may be preserved, and there is great being hereinafter fully set forth. Y saving of weights over the old system.
Figure l represents a rear View of a por- Having thus described my invention, what I tion of a loom havinga warp-tension embody- I claim as new, and desire to secure by Letters 6o ing my invention applied thereto, one end Patent, isthereof being only partly rigged. Fig. 2 repl. A warp-tension for a loom, consisting of resents a side elevation thereof. Fig. 3 repa warp-beam having iianges,brackets adapted resents a section on line fr Fig. l, on an ento be secured to the loom-frame and having larged scale. grooves, a slot and eyes, pockets with ears 65 Similar lett-ers of reference indicate correfitting in said grooves and with depending sponding parts in the several gures. teeth, securing-bolts for said pockets and Referring to the drawings, A designates brackets, levers fulcrumed in said pockets, a portion of the frame of a loom, and B desand cords passing around said flanges and seignates the warp-beam which is mounted cured to the eyes of said brackets and to le- 7o thereon. vers, said parts being combined substantially C designates the tension ropes or cords, the as described. same passing over the beam-flanges D and 2. The bracket E, provided with the groove each havingone end connected with abracketV H2, the slot K, and a series of openings P, the E and the other end with a lever F. pocket G, with the depending tooth M within 75 Gdesignates pockets, which are provided the same at the upper end thereof and the with ears H, the latter being tongued, as at tongued ear I-I at the rear, said ear entering H', and fitted in grooves H2 in the brackets, said groove H2, the bolt .l ,passing through the and through the ears are passed bolts .I,which ear Eand slot K, the lever F, fulcrumed in are also passed through the slots K in the said pocket on the tooth M thereof,'the -beam 8o brackets E and secured by nuts L in. the rethe flange D on said beam, and the rope C cesses L therein, said brackets being rmly on said iange connected with Vthe fulcrum attached to the back rail of the frame.
