IMPROVEMENT IN TAKE-UP FOR Looms.

The Schedule referred to in these Letters Patent andv making part of the lame.

To all whom 'it may concern Beit known that I, GEORGE H. HOLMES, of New Brunswick, in the county `of Middlesex,an d State of New Jersey, have invented a new and useful Improvementin Looms; and I do hereby d eelare that the fol- -lowing is a full, clear, and exact description thereof,

which will enable others skilled in the art to make and use the saine, reference being had' tothe accompanying drawings, forming part of this specification.

This invention relates to a new and useful improvement in looms, for weaving cloth, having particular reference to the take-up of the cloth; and

'lhe cloth-beam is seen at F, where the frame is broken away in the drawing.

Gr' isa 'gear-wheel on the end of the cloth-beam, which meshes into another and smaller wheel, on a short shaift which passes to the outside of the. loom, through a sleeve-box, H, attached to' the frame which hears thelratchet-wheel I.

J is a level' confined on thev ratchet-shaft, but free to oscillate thereon.

Upon its upper end .is pivoted a dog or pawl, k, which engages with the ratchet-teeth and revolves the ,cloth-beam when the 4cloth is taken up.

-There' may be a slot in the upper end of the lever, so that this pawl k can be adjusted to larger or smaller ratchet-wheels, ii' desired, which would be found couvenient in attaching my f take-up to old looms.

L is a rod, which connects'the lower portion of the lever with the lay of the loom, by means of an arm, in, projecting from the legga. A

or diminished at pleas'nre. o 4

On the rod L'there '1s a spiral spring, O, one end of The lower port-ion of the lever J is slotted, and the rod is fastened, by a bolt, in this slot, so that the throw'of `the upper end or pawl k, may be Aincreased which bears against the arm m, and the other end against a nut, p, by which the tension of the spring is increased or diminished as may be'deslred.

The arm m of the lay slides 0n therod L, and against the spring 0, compressing the spring more or less at each strokeor heat of the lay, according to the tension ofthe cloth. Y

When the cloth is slack, the spring wil] be but slightly (it` at all) aiiected'by the arm fm, its strength.

when forced by the arm will move the lever suliciently to make the pawl revolve the cloth-beam and take up the cloth, but when there 'is surricient tension on the cloth, the arm will expend its blow in compressing the spring, and will .not throw the lever -i'ar enough to move the ratchet.

vBy this arrangement, the take-up is more uniform than by any method now in use, the texture of the fabric is left even and uniform.

' The nut p, by which the tension of the spring is adjusted, may be turned automatically, by suitable mechanism connected with the warp-beam E, so that i the tension ofthe spring may be regulated according to the diameter of the warp-roll on the beam.

l do not confine myself to the use of a spiral spring on the rod L, other forms of springs may be applied, so as to produce thesame or similar eiiect.

-Having thusdescribed my invention, Y

I claim as new, and desire kto secure by Letters c Patentg The slotted lever-J, pawl k, ratchet-wheel J, gear- Y wheel'G, the rod L, spring O, nut j), and arm fm, the lay B, and cloth-beam F. of the loom, when arranged, with refercnce to eachv other, substantially as herein shown and'descrihed, for the purpose specified.

The above specification signed by me, this 6th day of May, 1869.

GEQRGE H.. HOLMES.
