SPECIFICATION forming part of Letters Patent No. 570,234, dated October 27, 1896.

Application filed May 8, 1895. Serial No. 548,565. (No model.) Patented in Germany February 6, 1894:, No. 78,217, and in Austria-Hungary June 26, 1894,110. 1,329 and No. 22,736.

To all whom it 11mg concern:

Be it known that I, CHRISTIAN SE'YBOLD, a subject of the Emperor of Germany, and a resident at Zweibriicken, in the Kingdom of Bavaria, Germany, have invented new and useful Improvements in Looms, (for which I have obtained Letters Patent in Germany, No. 78,217, dated February 6, 1891, and in Austria-Hungary, No. 1,329 and No. 22,736, dated June 26, 1894,) of which the following is a specification.

My invention refers to improvements in letoff and take-up movementsfor. looms, the

nature of which will be fully explained in the following specification, in connection with the annexed drawings, in which- Figure 1 represents a side elevation, partly in section, on the line 1 1, Fig. 2, of part of a loom provided with my improvements. Fig. 2 is a sectional plan of the let-off and take-up movements, the section being taken on the line 2 2, Fig. 1. Fig. 3 is a similar sectional plan of a modification.

Similar letters of reference designate corresponding parts throughout the several views of the drawings.

Referring now to Figs' 1 and 2 of the drawings, the letter T designates one of the side frames of a loom; M, the warp-beam; N, the cloth-beam, and A the lay or lathe.

L is a shaft mounted in the frame T and carrying at its inner end a bevel-gear '6, engaging a bevel-gear 7.: on a shaft .2, Fig. 2, the opposite end of which carries a worm 9, engaging a worm wheel q, placed on the shaft of the warp-beam M between the frame and the end of the warp-beam M. Upon the outer end of the shaft L is mounted a pinion g, and between the latter and the frame is placed a ratchet-wheel r.

a is another shaft mounted in the frame and carrying at its inner end a pinion m, engaging a gear-wheel a, mounted between the frame and the cloth-beam and upon the shaft of the latter. Upon the outer end of the shaft a is loosely mounted an internally-toothed wheel f, into which the pinion g on shaft L meshes. Fixed upon the shaft a is a gearthe inner teeth of the wheel f and the teeth of the fixed wheel b.

\V is a weight suspended 011 a rope or chain 5, passing over a pulley o and attached to the wheel 0.

Bis an arm projecting from the lay and connected to apawl-oarryin g arm H by means of a rod 0, bell-crank lever D, rod E, lever F, and rod G, whereby motion is imparted to the ratchet-wheel r from the lay.

The operation of the above-described apparatus is as follows: During the forward motion ofthe lay the arm 13 is depressed, the rod E pushed toward the right, and the rod G, with the pawl-arm H, to the left, the pawl sliding over the teeth. During the return motion the ratchet-wheel r is turned a certain distance, and with it the pinion g, as well as the bevel-wheel 1', which latter, through bevelwheel 7t, worm p, and worm-wheel q, turns the warp-beam a certain amount, letting off the warp correspondingly. The pinion g, under the action of the ratchet-wheel, is turned to the right, and under the action of the weight 1V to the left, and is then free to adjust its position; but under the action of the weight it will transmit a uniform moment of force to the cloth-beam; that is to say, the force will be constant for a given radius. 13y properly proportioning the parts, and in particular the wheels 15 and 7c of the let-01f, the weight WV need not be wound up in weaving ordinary lengths of goods. Assuming the rope-wheel with the axis cl of the planet-wheel e to remain stationary during a forward movement of the ratchet-wheel, the cloth-beam would be moved forward a fixed amount, but if this should cause too much strain the weight V will yield and reduce the motion of the cloth-beam.

Fig. 3 shows, on a larger scale, a modification of the apparatus shown in Figs. 1 and 2. In this figure r is the ratchet-wheel, the shaft of which carries a pinion g, meshing into the outer teeth of a gear-wheel f, loosely mounted upon a shaft a. This gear-wheel f" has a bevel toothed rim, and a similar bevel-wheel b is mounted on the same shaft a. Between the two bevel-wheels is placed to mesh with the same a bevel-pinion e, mounted on the rope-wheel c.

The operation of this apparatus is substantially the same as that of the apparatus shown in Figs. 1 and 2.

hat I claim as new is 1. In a combined let-off and take-up for looms, the combination with the warp-beam, the cloth-beam and the lay, of a ratchet-wheel, an operative connection between the lay and said ratchet-wheel, means for transmitting motion from the ratchet-wheel to the warpbeam, a pulley, means for subjecting the same to a constant turning stress, a planet-wheel carried by said pulley, and two toothed wheels meshing with the planetwvheel; a shaft; one of said wheels being fixed upon said shaft and geared to the cloth-beam, and the other wheel being loose on the same shaft and geared to the ratchet-wheel, substantially as and for the purpose set forth.

2. In a combined let-off and take-up for looms, the combination with the warp-beam M, the lay, and the cloth-beam N, of a ropepulley c, a rope s, a weight V connected by said rope with said pulley, a ratchet-wheel 0, an operative connection between the lay and said ratchet-wheel, means for transmitting motion from the ratchet-wheel to the warpbeam, a shaft to geared to the cloth-beam, a toothed wheel f geared to the ratchet-wheel shaft and loosely mounted on said shaft a, a toothed wheel Z) fixed to the shaft a, and a planet-wheel 6 carried by the rope-pulley c and meshing into the wheels I) and f, substantially as and for the purpose specified.

3. In a combined let-off and take-up for looms, the combination with the warp-beam, the cloth-beam and the lay, of a ratchetwheel, an operative connection between the lay and said ratchet-wheel, a wheel g on the Warp-beam shaft between the end of the warpbeam and the frame, an operative connection between said wheel and the ratchet-wheel, a rope-pulley, a rope, a weight connected by said rope with said pulley and tending to turn the same, a planet-wheel carried by said pulley, a shaft a, two toothed Wheels meshing with said planet-wheel, one of the said wheels being loose upon the shaft a and geared to the ratchet-wheel, and the other being fixed upon the same shaft a; a toothed wheel a fixed upon the cloth-beam shaft between the clothbeam and frame, and a pinion m fixed on the shaft a and meshing with the wheel a, substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
