LOOM FOR WEAVING CHENILLE OR FUR PILE FABRBCS.

SPECIFICATION forming part of Letters Patent No. 324,287, dated August 11,1885.

Application tiled February 0, 1883.

To all whom it may concern:

Be it known that I, WILLIAM ADAM, (of the firm of 'Iomkinson 8L Adam,) a subject of the Queen of Great Britain, residing at Kid derminster, in the county of Worcester, England, have invented certain new and useful Improvements inv Looms fOr'VVeaving Chenille or Fur Pile Fabrics, (for which I have received Letters Patent in Great Britain, No. 3,087, dated th June, 1882,) of which the following is a specification.

My present invention has for its object improvements on an invention for whichUnited States Letters Patent were granted to me dated August 22, 1882, No. 263,085, and relates, rst, to means for insuring the chenille or fur pile being brought up into its proper position. For this purpose I so construct the cam giving the rising and falling motions to the reed as that in the working of the loom eXtra falling and rising` motions shall be imparted to the reed, so as to cause the same to strike the chenille or fur last inserted a second time with the inclined upper ends of the dents, the reed afterward rising in its backward motion to enable the shuttle to go across-the loom.

According to the second part of my invention I employ a fixed guide-reed placed as close as possible to the track of the catcher warp needles, in order to steady the groundwarp threads, and thereby insure the said needles entering their proper spaces between the ground-warp threads.

According to the third part of my invention I so construct the cam giving thel rising and falling motions to the catcher-warp needles that the full downward traverse of the said needles is divided into three separate falls, in order to. facilitate the setting and holding of the chenille or fur pile as it is being brought into its proper position.

According to the fourth part of my invention, when it is required to insertan eXtra or a floating warp, I employ, as heretofore, an extra shaft or leaf of healds, but instead of operating such eXtra shaft or leaf in theA manner heretofore adopted, I operate it by means of the other leaves or shafts, or by some of them, according as it is required to raise such extra shaft or leaf at the rise of every heald or at the rise of only certain of them. This I effect (No model.) Patented in England June 30, 1882, No. 3,037.

by mounting at the top of such extra shaft or leaf one or more projections capable of being fixed in position by screw or otherwise, so as v to extend over some or all of the other shafts or leaves, or over projections therefrom, and

thereby cause such extra shaft or leaf to be raised at the rise of every shaft or leaf, or at the rise of only some of them.

And in order that my said invention may lbe more clearly understood and readily carried into effect, I will proceed, aided by the accompanying drawings, more fully to describe the same.

In the drawings, Figure 1 is a cross section,

-and Fig. 2 is a sectional side view, of parts of a loom for weaving chenille or fur pile fabrics,

showing my present improvements applied thereto. Figs. 3 and 4: are respectively a vcross-section and a horizontal section of parts particularly the cams for operating the lathe and the healds with their connections.

In all the figures like parts are marked with similar letters of reference.

' In the said drawings, my improvements are shown as applied to such a loom as is represented in my said previous Fatent,No. 263,085, it being understood that the chenille or fur is inserted inthe open shed (formed by the ground-warps and thecatcher-warps) by means of a finger or traverser, which carries the said chenille or fur through that shed from one side of the loom to the other.

a is the main framing.' b is the first-motion shaft. c is the cam or tapped shaft. d d are the lathesw'ords. e is the reed. ff are the catcher-warp needles. g g g are the shafts or leaves of healds which are operated in the usual way, andrh is an extra shaft or leaf of healds operated in manner hereinafter dcscribed. V

The reed e is operated, as described in the specification of the Letters Patent hereinbefore referred to,and as shown herein at Fig. 1,

by cams e', which, by levers ci and connect.

ing-links e3, give a downward motion to the reed e, while springs e4 give the upward mo- IOO tion thereto. According to such former pat cnt, however', only one fall and one rise were given to the reed at each revolution of the cam e-tl1at is to say, for each insertion of chenille or fur but according to the first part of my present invention I so construct the cam e' that it shall impart two falls and two rises to the reed c at each revolution of the said cam. This construction is shown in Fig. l of the drawings, where the cam c' is represented as being provided with two falling grades, s' S2, and with two rising grades, I. t, which grades operate upon the truck of the lever ei in the manner in which cams usually act upon their levers. By constructing the cam c as shown in the drawings I cause the reed e, as described in my said former specilication, iirst,to strike the last-inserted chenille or fur with the inclined faces of the upper ends, cii, of the reed e, (that is, when down.) and then to rise so as to stroke np the chenille or fur pile. The reed e retires from the fell of the work in this position, and then in again coming forward it is caused, according to my present invention, to fall, and again to strike the chenille or fur pile with the upper ends, 0*, after which it again rises as it recedes, to enable the shuttle to run across the loom. The reed e then falls and again strikes the work when down, after which it remains down, while the lathe goes back to rest, in which position of such parts-that is,when the lathe is back and the reed down-the fur or chenille is carried across the loom. By thus causing the reed to strike the chenille twice the portions of the fur pile which have not been struck up by the first blow of the reed are acted upon by the second blow thereof, and consequently the fur pile is struck up with much greater uniformity than is practicable when it is operated upon but once by the reed.

The means which I prefer to use to operate the lathe when the reed is moved, as above described, are represented more particularly in Figs. 5 and (5. Each sword d of the lathe is connected by means of a toggle-link, d, with an arm, d, which is fitted to vibrate freely upon the first motion-shaft b. Each of these links d is operated by a cam, d, secured to the camshaft c, the cam operating upon the link through the intervention of the truck (1*, lever d, and rod d6, which last is, by preference, made adjustable, as represented in said drawings. The grades di of the lathecams d are constructed, as represented in said Fig. 6, so as to raise and depress the respective toggle-links d, and thus move the lathe forward and backward. As the cam-grades d occupy only a part of the periphery of the lathe'cams d, thelathe remains at rest during a part of each revolution of the cams-that is, alter the last cam-grade in the series has operated until the first camgrade is brought around to the lever-truck d.

According to the second part of my present invention I employ a fixed guide-reed, t', as shown, placed as close as possible to the track of the catchcr-warp needles f f, and of the same gage as the latter in order to steady the ground-warps, and thereby insure the said needles entering their proper spaces between the ground-warp threads.

According to the third part of my present invention I divide the full downward traverse of the catcher warp needles j f into three separate falls and dwells, in order to facilitate the setting and holding of the chenille or fur as it is being brought into its proper position. For this purpose I employ, as described in my said former specification and as shown in the accompanying drawings, a cam, here lettered j", which, by a lever, f2, connecting-rod f", and lever f gives the rising and ihlling motions to the catcher-warp needles f f but instead of giving merely one rising and two falling motions to such catcher-warp needles ff in the full extent of their traverse, I construct the cam f, as shown at Fig. 2, with three grades, so as to divide the full downward traverse of the catcher-warp needles ff into three separate falls, the first of which is determined by the grade 1*, and carries the catcher-warp needles ff down to the posi tion marked l, Fig. SAthat is, sufficiently far to enable the catcherwarps to hohl the chenille or fur and to remain in such position while the latter is being adjusted, and yet permit the weaver readily to draw the selvagethread from under and beyond, so as to place it outside the chenille or fur when the latter is turned at'the selvage. The second fall is determined by the cam-grade 2*, and carries the catcher-warp needles f f down to the position marked 2, Fig. S-that is, sufficiently far for the catcher-warps to securely hold the chenille or fur in its adjusted position-in which position the catcher-warp needles ff remain while the chenille or fur is being beaten and stroked up. The third fall is determined by the cam-grade 3*, Fig. 3, and carries the catcher-warp needles ff down to the position `marked 3 in Fig. S-that is, to the bottom of the shed-where they remain sufficiently long to enable the shuttle to be thrown across the loom the required number of times to bind the catcher-warps, and consequently the chenille or fur. They then again rise and return to the position marked 0, where they remain while the chenille or fur is being carried across the loom.

According tothe fourth part of my present invention,when it is required to insert an extra 01 a floating warp I employ, as heretofore, an extra shaft or leaf, 7L, of healds; but instead of operating such extra shaft or leaf h in the manner heretofore adopted I operate it by means of the other leaves or shafts g g g, or by some of them, according as it is required to raise such extra shaft or leafh at the rise of every heald g g g, or at the rise of only certain. of them. rlhis I effect by fitting the upper bar of such extra shaft or leaf lo with one or more projections or studs, h, Fig. 3, capablc of being f1xed 1n position by screw or oth.w

erwise, so as to extend over some or all of the other shafts or leaves g g Lf/,or over projections therefrom, and thereby cause such eXtra leaf or shaft h to be raised at the rise of every shaft or leafgg g, or at the rise of only some of them. The Ymeans by which I prefer to operate the said leaves or shafts g are represented more particularlyinFigs. 5 and 7 ofthe drawings, each leaf g being operated by anappropriate cani, g', through the intervention ofa truck, g2, lever g3, rod g4, and overhead lever g5, from the inner end of the last of which the leaf is suspended. The cams g', two of which are shown in the drawings, are secured to. the cam-shaft c. I have used and have described cams for operating the reed, the catcher-warp needles, and the shafts of the groundwarp threads, but equivalents for these may be used for the same purpose.

I-Iaving thus described the nature of my said invention, and the mode in which I carry the same into effect, I would have it understood that what I claim is- 1. The combination, substantially as before set forth, of the reed of the loom with cams constructed with two falling grades and two rising grades, whereby two falls and two rises are imparted to the reed for each insertion of the chenille.

2. The combination, substantially as before set forth, of the cams e, constructed and operating as described, with the levers e2, connecting-links e3, springs e4 c, and reed e.

3. The combination, substantially as before set forth, of the catchenwarp needles with the guide-reed, which is set close to the track of said needles so as to steady the ground-warp threads and insure the entrance of said needles in the spaces between said ground-Warp threads.

4. The combination, substantially as before set forth, of the catcher-warp needles with a cam constructed with three grades, whereby the descent of the said needles is divided into three falls, substantiallyas described.

5. The combination, substantially as before set forth, of the cam f', constructed with three cam-grades, the lever f2, connecting-rod f3, lever f4, and catcher-warp needles f f.

6. In combination with the leaves or shafts g g g of healds, the eXtra leaf or shaft h, and projection or projections h, extending over and operated by some or all of the leaves or shafts g g g or by projections therefrom, substantially as herein shown and described, and for the purpose stated. v v
