TO ALL WHOM IT MAY CONOERN:

Be it known that I, GEORGE W. RAY, of Springfield, in the county of Hampden, and ,State of'Massachusetts, have invented a new and useful Improvement -up'on Machinery for Embossing Paper for Articles of Wearing Apparel; and I do hereby declare that the following is a full, clear, and exact description'of the construction and operation of thesame, lreference being had to .the annexed drawings, making a part of this specification, in which Figure 1 is a longitudinal elevation.

Figure 2" is a transverse section throughtline'A B of. Iig. 1.

Figure 3 is a plan of a metallic plate, covered with a woven fabric; and.

Figure 4 is a sectionof fig. 3 through line a a. l

The nature of my invention consists4v in Vthevconstruction of apparatus for using a Woven fabric under aheavy pressure, for the purpose of embossing paper, either before or afterits conversion into articles of wearing apparel, by forcing the-woveufabric into the surface of the` paper, so that the paper may present an exact negative of the fabric, instead o f using metallic dies, said fabric, or its production, forming the subject of mv application tiled March 28, 1865. v

Iny the drawings, AA. is a cast-iron frame, firmly braced and held by the rods Zi b, in which frameis an aperture, g, made to receive Athe sliding boxes e e, which are the bearings ofthe rolls ad. The' upper roll c, has itsjbcarings or boxes upon the upper side,4 and it rests upon and communicates its motion to'the lowerroll, and screws, are provided to force the upper roll c do'wn upon the lower roll d when it is desired to obtain greater pressure. lThe upper roll c is coveredwith any desired woven fabric which I-wish to imitate. It may be well to first varnish over the surface of themetallio roll c witha thin solution of shellac, or its equivalent, and before it is entirely dry 'stretch overv its surface the fabric to `be imitated, and bring the two lends ofthe fabric together, so thatthey shall be exactly even and level upon the face of the roll. The upper rolle is then-forced down upon the 'lower roll d by means ofthe screws so that there maybe suiiicient pressure, and motion is communicated by means of the pulley z'. The woven fabric, when bedded and held {irmby the shellac, becomes perfectly solid und hard, and becomes in itself a. die, fromiwhich many thousand impressions can be taken without injury tothe fabric. It is obvious that, .instead of covering'tlie roll c,,thc fabric might be carried around 'the rroll e and over au auxiliary lroll placed above it, in the form of an'endless belt,-o it might be a long. piece of goods, reeled from one roll,lcairied between the embossing rolls c d, and reelcd upon another roll upon the other side. To secure eas-y manipulation of the paper and a good impression, however, it is best that the fabric should bc as solid 'as possible. I also cover a metallic plate, p, with'an'y fabric which I wish to4 imitate, on either one or -both sides, and whenlIemboss paper in the sheet, caniwhe'n the plate is covered on both' sides with the fabric)l emboss two or three sheets at once, by placing'V two sheets faced to the covered plate, .one on `each side, and still another faced to the covered roll,and Athen pass Athe covered platep, with the paper, between the rolls.

When embossing paper in' the roll, oriu a continuous strip or sheet, I placethe roll of'papcr upon one side of the machine, in such position as that 'it shall be unrolled easily and freely, and pass it between the rolls' without using thecovered plate, and as fast as itlpasses through and is embossed, roll it up upon another roller on the other side of the machine. After ,startingiu this way it needs no particular attendance until completed. The rapidity with which I canA changefrom one quality orkind of fabric to another (as the roll can be covered with anydesired fabric in ten minutes) obviates -the lexpense-and sometimes perplexing delays of manufacturing and waiting for metallic dies', and, as many thousand sheets cani beerubossed from one piece of goods without materially injuring it, ythe manufacture of imitated cloth goods from paper, which* article-is Vnew becoming extensively used and ,introduced in commerce, is verymucli chcapened and facilitated.' l

I do not claim to emboss by means of rolls alone, vas. this'has been practised heretofore, but iu doing so it has been necessary to have the rolls engraved, either one or both of them,` a 'practice which involves much time, labor, and expense, and even` then itis foundimpossible to mak-e anl 'engraved roll' which will produce an exact and perfect negativ-c imitation of the fibre and igureof a fa,bric,'especially the liner q ualities of linen and m'uslin;y but by myv method I can-produceuu exact and perfect imitation of any` fabric,"l1oweve'r fine ortcoarse, s0 that even the twist of the thread-may be seen in theimpression by the aid of a glass.- Neither do Iclalm to emboss by mens of electrotyped oi any other 'metaldl-icdies, as I am aware thatl this has alsobeen done heretofore by varius similar means and devices; but, having described my invention, what I do claim as new, and

desireV tov secre by Letters Patent, iis-'- l. The roll c, covered, or partially-covered, with a, woven fabric, in combination` with. the roll d, substanl tiallyas described and for. the purpose sieb foith.

2. The plate p, in combinatio Wiihthe roll c and roll d, ovnev or more of these parts being covered, all

substantially asfdescribe and'fr the purpose set fornh. y
