JOSEPH "I-IASLAM 1n his lifetime l, .didf invent Thread of `One MaterialiwithlafCoating of a` Dierentl Material by WhichCertainUse ful Results `are Secured; and we further de- "clarethat the following speciication, taken 11s. j in connection` lwithl-thedrawings, `is a full a and gexact" descriptionfof the invention of saidJosErrrHAsLAMu i Inmany bf" textile fabrics a fine `surface or onecomposedof costlylmaterial is a desideratum, but the interior part of the fabric may be `composed of aless costly material, not onlywithoutinjury to the fab- "rcfas a wholeubut even" to its benefit." A

coarse `and "strong interior would tend to the durability of the article and would moreoverenablelthe manufacturer to afford it at 'a less price evenwhen 'more material was "employed andathicker, warmer andmore durable fabric "wasithe result.` `This object f1 has been attainedby employing `threads of f `a cheaper material whichfin the process of weaving wereqthrownbeneath the Vsurface a orf at any rate appeared thereon only f slightly and it hasalsobeen attempted by whollyfcovering, each particular thread of cheap material'with a coating of a more p`costly one.` Thislatter idea has from imperfection of the processin the one* method 1 or from its great costin another plan .been l.hitherto practically unsuccessful.` By the former` method it was essayed to take `a ffrollfof the `fine materialdirectly from the carding machine andwith this cover a hard thread. The failure" arose probably from the want of tenacity of the covering which therefore tended to apply itself inlspots `instead ofbeing diffused yequally over vthe l `whle surface of the inner thread. It

would `moreover be diiiicultto cause the inf sidethread tobed itself truly in such a dif- `fuse mass and `our `belief is that the inventor of that process devisedno plan for bedding one material in` the other before twisting usual PATENT OFFICE: "AM, Yi .ioHN nsLAM, or romania-D` gms.. riAsLAM,z or

`them together and further that henever was 1 awarefofthe absolute necessity course.` V

of suchA a The nature of 1J osEPH HAsIaaMsinven-` "tion consists in covering a thread of one` material. with other material applied there- 1 to" either as: aroving or as a slacktwisted yarnhandalsoen bedding theformer intox `l the "latteriprior"toLtwisting` the two together: For* this purpose he` availedv himself. of well known "machinery of any usual kind the essentials," thereof being drawing rollers and a flier and bobbin or their equivalents.

` In his process a roving or a loosely twisted thread either in a can or on a bobbin and prepared either in a drawing or a throstle frame or in any well known way is passed through drawing rollers, or through a single pair of rollers only on its way to` a flier, while a harder thread of less costly material taken from a. bobbin, cop or otherwise is passed through the same `rollers or some of them, in such manner `thatfthe latter is guided so as to pass through in contact with the center of the former or nearly so, and is by the pressure of the rollers bedded into it. The, combined threads then pass to a flier which twists the mass and completely cover 4the one material with the other, the coating being equable and its thickness being regulated either bythe original size of the roving or yarn, or by the reduction thereof durin its passage through some of the drawing ro lers `before itf comes in contact with the inside thread.

In the drawings a machine fit for per` formin this pro-cess is represented. In the beneath the'table. The apparatus for moving these rollers is not represented in the drawing: through all these rollers passes theroving o from the can d, or if a loosely twisted yarn be employed, it follows the same track and is supplied from a bobbin occupying `thesa-me position as can d. A

Ihard thread of coarse material wound Aon bobbin e passes through the guiding eye f,

over rollers a2 and a3 and between rollers rame are represented three sets of l a a where it is bedded into c c, the two threads then enter flier g, and after being twisted together are deposited upon the bobbin h. i

It will be perceived that the thread of coarse material travels over rollers a2, and a3 in a direction contrary to their motion. This course puts a drag on the thread previous to its entry between rollers a a and insures its being bedded in the roving or loosely twisted thread.

It is apparent that the form and number of parts in the apparatus may be materially varied, while it is still applicable to lthe process described and also that well known equivalents of these parts may be used in place thereof to secure an equally good result.

This process is chiefly applicable to the covering of cotton with wool, or silk but is useful also for covering coarse wool. with line, and we intend by means thereof to make a substitute for satinets and all those goods which are composed at present of mixed materials in distinct threads.

We claim as of the invention of JOSEPH HAsLAM deceasedi The method of bedding one thread into a roving, or loosely twisted thread of another material, as also the covering of one thread b a roving or loosely twisted thread of a di erent material, substantially in the manner and for the purposes herein set forth.

In witness that the foregoing is a true description of the invention of said JOSEPH HALSAM deceased we have hereunto set our V hands in the city of New York county of New York State of New York on this ninth day of Novr. 1854.
