SPEOFIGATION fori-ning part of Letters Patent No. 691,088, dated January 14, 1902.

Application tiled August 2O.y 1901. Serial No. 72,651. (No model.) A

To ttt/Z w/tom/ t wwf/y concern:

Be it known that I, EDWARD WACKER- HAGEN, a citizen of thc United States, and a resident of Fort Lee, in the State of New Jer* sey, have invented certain new and useful 1mprovements in Looms, of which the follow* ing description, taken in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to improvements in looms, and has for its object to prevent the sticking of the warp threads or completed web to the front and rear glass rods, occasioned by the presence of excessive moisture in the atmosphere.

In the weaving of silk fabrics, as in the weaving of other fabrics, the operation is unfavorably affected by the humidity of the atmosphere which often prevails in the factory either through natural or artificial causes and which is either too high or too low for the best results in weaving. At such times the warp adheres to the rear glass bars and the web adheres to the front bar in a way to produce a bitching motion rather than a regular even progress of the warp and of the web over these bars, with the result that the weftthreads are laid unevenly in the web. My improvement remedies this difficulty.

It is essential to good weaving that the warp should pass the rear glass bars, as the web should pass the front glass bar, evenly and regularly with each stroke of the batten, and to secure this the regulatonroll o r clothbeam C, as the case may be, is actuated by a ratchet which secu res this regulator intermittent motion but if from the action of humidity in the air or other cause the warp-threads or the web adhere to the bar unduly the regular intermittent motion essential to good weaving is not obtained, and the cloth-beam or regulator-roll continues its motion, but the web will pass one or two or three strokes of the lathe without any progress of the warp or of the web over the bars. The result is that the weft is laid and beaten up unevenly, and the web is of uneven texture at such a point, unduly compact for a few threads of the lling, and then too loose.

l Vth looms making high-grade silk fabric it has been found necessary to stop work whenever the humidity of the atmosphere exceeded about sixty per cent. The loss entailed both to the weavers and to the manufacturers was enormous, and the time when this loss would be inflicted could not be foretold, since it is wholly dependent upon the state of the weather. By this invention AI have overcome this diflculty.

In the drawings forming part of this specication, Figure l is a side elevation of a loom, illustrating my invention, parts being shown in section. Fig. 2 is a plan elevation rof a modification of my device. Fig. is a View, partly in section, further illustrating said modification.

In the form shown in Fig. 1 my invention consists in a slat of wood A, fastened to the lower side of the lathe, projecting forward from it about two inches in such wise as to tap the web a light blow and press it outward from a straight line about two inches at a point below the front glass bar and between it and the regulator-roll. The warp-beams or warp-rolls weighted for tension are not shown in the drawings, but are in the upper part of the loom from which the warp is led downward around the rcarglass bars R, where the principal difficulty occurs which this invention remedies. Then the warp passes toward the front of the loom through the back reed, (not shown,) through the eyes of the heddles H, thence through the reed RQ, which is the ultimate distributer of the warp and the instrument by which the warp is beaten up and closed in weaving.

The web of the finished material is formed and begins at W and passes over the front glass bar G at the front of the loom to the regulator-roll C, which in ribbon-weaving is the substitute for the cloth-beam in. clothweaving. Above the regulator-roll G is the pressure-roll P, whichmaintains the tension. This regulator-roll C is slowly actuated by the ratchet connected with the power which drives the loom to apply proper tension to the material as the web is augmented at 1V.

A strip of wood A is fastened to the lower part of the lathe B below the shuttle-race and projecting forward from the batten perhaps two inches; but it is adjusted to stand out from the batten just far enough to deliver a light tap to the web between the glass rod at IOO C below just in advance of the impulse of the batten striking the weft home, as illustrated in dotted lines in Fig. 1. This slat attached to the lathe not only administers a blow to the web, but presses'it forward to increase the tension, and I have attained the best results by timing this blow and pressure just prior to each stroke of the reed. The same result might be less perfectly attained by an independent bar actuated in any convenient manner independent of the motion of the lathe, which should administer a blow to the warp or to the warp-threads at any point between the Warp-beam and the cloth-beam or which should deliver a slight blow to the glass bars themselves or to the frame of the loom, so as to dislodge the warp or the web from the bars; but the best manner in which I have contemplated using my improvement is bya slatattached to the lower part of the lathe, which is a cheap and expeditious device for overcoming this difficulty in a most effectual way.

Figs. 2 and 3 illustrate a modification of my device which consists in making the attachment to the lathe in the form of a frame A', said frame surrounding the finished web. By this construction the same result is accomplished as in that heretofore described,

the difference in operation being that the eenoss other constructions may be made to perform the same result in substantially the same way-as, for instance, practically the same result could be secured by striking the bars instead of the'material being woven. I consider all these various and obvious arrangements as coming Within my invention and discovery.

Vhat I claim, and desire to secure by Letters Patent, is-

1. In a loom, the combination of the front and rear rods, and'means for loosening the material from said rods periodically, substantially as described.

2. In a loom, the combination' of the front and rear rods and means actuated by the lathe for loosening the material from said rods periodically, substantially as described.

3. The combination with a loom of a lathe having a projection thereon so placed as to strike the web when the lathe swings, substantially as described.

4. The combination with a loom having suitable means for guiding the warp-threads both before and after the weft is incorporated of means striking said threads near one of said guiding means periodically, substantially as described.

In witness whereof I have hereunto set my hand, at New York, in the county of New York and State of New York, this 19th day of August, 1901.

EDWARD VAOKERHAGEN.
