Letters Patent No. 87,620, dated'March 9, 1869.

IMPROVEMENT 1N MACHINE-fron 'rwrs'rme BULLIoN-PRINGE.

The Schedule Areferred to in these Letters Patent and making part of the same.

To all w'hom 'it mol/ 1] concern.-

vuseful Improvement in Looms for Making and Twist.

ing in the Loom, Bullion-Fringe and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same,

part of this specification, and to the letters of reference marked thereon.

Figure I, Sheet I, represents a side elevation of part of a loom with my improvement attached.

Figure II, Sheet II, represents a top view, and

Figure III, Sheet I I, a front view of my improvement.

Similar letters represent similar parts in all the iig'- ures.

My invention consists in the construction and arrangement of parts, and the combination of the same, substantially as hereinafter set forth.

In the accompanying drawing- .-I represents part ofthe frame of the loom.

B represents the swinging frame, or movable batten,suspended by the rod C, at any convenient and suitable part, at the top of the loom-frame, and operated by means of 'the connectingrod D,l connected to a crank, E, attached to the crank-shaft F, constructed in the usual manner, so that, at 'each end of vits motion, this swinging batten B will remain some time To this hatten B, the reed G, constructed in the usual manner, is attached. l i

Qn the end of the. frame, or hatten B, a toothed wheel, H, is attached, turning on a suitable bearing, and operated by a pinion, e, fast on the end of a shaft,I b, situated on the top of the swinging frame', or batten B.

meshing into a pinion, n, turning, in suitable bearings, in the frame h, attached to the front part of the hatten B.

Through'this pinion n, a spindle, m, passes, having, on-the end nearest the reed G, a hook, fu, and on its other end, an arm, u', which latter is connected with the hook-bar s, situated on the front of the hatten B. The hook-,spindlem is provided with a long feather, or key x, fitting into a suitable recess in the heel of the pinion u, to allow the same to slide backward andA On this shaft b, a toothedwheel, d, is fastened,'

i 4 To the wheel H, a plain wheel, J, is attached, provided w-ith a recess, or cavity n., (see Fig. I,) into which a pawl, or the end of a lever K, iits, for the purpose of holding the said wheel H, and, through the same, the pinion a and shaft b, as well as all parts c'onnected with, this shaft stationary, during certain :times of the' operation of the loom. reference being had to the annexed drawings, making a To the pinion a, a pulley, or band-wheel V, is attached, connected, by means of a belt, g, wit-h a pull ley on the loom, for the purpose of communicatingmotion to the shaft b, and the parts attached to the same, except when stopped, by the action of the lever K, against the recess u, ou the wheel J.

Instead of attaching the pulley V tothe pinion a,

or to the shaft I1, the same may be attached to the An arm, or lever Q, is attached to the end iof this shaft N, operated by a projection, z, fast on 4the pulley R, or by any other part of the loom, 1n such a manner as to operate the shaft N, and consequently the arm l, at the proper moment.

On the pulley Brwhich is attached to the crankshaft F, another projection, y, is attached, to operate the end of the lever K, so as to bring the same clear of the recess, or cavity u, in the wheel J ,and allow the belt g to operate the shaft b.

The operation of the loom is as follows After the warp-yarns have been separated by the action of the heddles, in the usual manner, ready for the weft or woof to pass through, the hook-bars is opsired distance to bring the weft through the warp, and

give the required length of --the loop on oneside of the warp, to 'form the fringe.

The warpeyarnsiare then changed by the action of the heddles, and the hatten B moved towards the breast-beam L, to tighten the weft.

By this motion of the hatten B, the belt g, running on the pulley V, is tightened, so as to communicate motion to said pulley and to the shaft b, and, at the same moment, when the hatten B arrives at the end of its motion, the projection y, on the pulley R, oper-y ates the lever K, so as to bring its end clear of the recess u in the wheel J, and allow thereby the belt g to rot'atethe shaft b, and give motion to the hook-spin-` dle m, through the gearing dand n, so as to twist the loop on the hook v as much as required, to produce the desired bullion-fringe.

At the completion of this operation, the amount and duration of which may easily be regulated by the relative proportion of theA gear-wheels, the end of thev lever K will fall again in the recess u on the wheel J, and stop thus the further motion of the shaft b, and,

y consequently, of the hook-spindle on.

The projection z, on the pulley R, operates then the lever Q, so as to move the arm P on the sliait N upward, throwing vthereby the twisted loop or fringe oli from the end of' the hook c.

The batten B is then moved bnck again, toward the crank-shaft F, ready for the next passage ofthe weft, when the same operation is repeated.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. rllhe arrangement of the sliding hook-spindle lm, having a feather, x, and working through the pinion n, in xed frame h, and connected, by means of arms w, with the slide s, all operating substantially as herein described.

2. The rock-shaft N, having a lever, Q, and arm, P, wht-relay the fringe is disengaged from the book, said shaft being operated by a tappet on the Wheel R, striking lever Q, as herein described.

3. The lever K, which engages with the notch u, when operated by means of a tappet on the wheel R, substantially as and for the purpose herein described.

4. The combination and arrangement of the sliding hook-spindle on, connected with 'slide s, the shaft b, gearing n (l, pinion a, wheels H J the latter having a recess u, the shaft N, provided n'itli lever Q and arm P, and the wheel R, carrying tappets y z, all operatf ing together substantially as herein described.
