To all whom it may concern.'

Be it known that I, GEORGE J. Brennan., of Boston, in the county of Suiolk and State or Massachusetts, have invented certain new and useful Improvements in Fabrics and Methods of Making the Same, following is a speciication.

This invention relates to themanufacture of light thick fabric adapted for the inaking of warm garments or for such uses as those to which q ts, comforters or puis are applied, .or which may be cut to any sizes desired and used'for sanitaryvabsorbent pads. The first mentioned articles are usually made by basting together two layers of cloth with an intermediate layer of cotton, wool, or down, while the absorbent pads usually comprise a layer of absorbent cotton batting simply spread between two pieces of cheese cloth or gauze, basted together.

rlhe ob'cct of my invention is to provide a woven abric capable of use for any or all of the purposes mentioned, the soft luiy material being so held that it is not, and can not become, locally bunched, but always remains equally distributed throughout the entire area of .the fabric be it large or small without unfilled portions or areas, so as to afford uniform protection when employed as a comforter or puff, or for making garments, and to provide for uniform taking up of moisture when employed for absorbing pur on hospital cots or elsewhere.

To these ends, the invention consists in the improvements which I shall now proceeBd to describe and claim.

1 gitudinal and transverse sections of a fabric constructed according to my invention;

Fig. 3 is a plan view-of a piece of the fabric;

Fig. 4 represen Y OfFig. 2,

Fi 5 1s a view similar to Fig. 4, of a. mo cation.

All of the gures are drawn to an enlarged scale. v

The fabric shown in Figs. 1 to 4, inclusive, comprises two sets ofwarp threads l and 2, two sets of weft threads 3 and 4, a set of tie warps 2, and a plurality of longitudinal fluffy padding strands 5 herein shown as loose slivers or rovings of carded fibers. The two sets of warp threads 1 and 2 are controlled by the harnesses of the loom in which the fabric is woven so as to provide two a section on line 1 -4;

of which the tained upon the warps gures 1 and 2 represent respectively lon-f Patented Juiyao, 191s.

Sheds a aus b an are Shuttles by which an,

thread i in d weft shed b exclusively with vthe result that two superimposed fabrics A and B are simultaneously produced.

The tie warps 2a are controlled by a separate harness frame which is so operated as to lift said warps into the upper half. of shed a atpredetermined intervals during the operation of the loom and at other times to maintain said stitching warpsV depressed within the Shed b. As shown in Fig. 4 these stitching warps 2a are lifted into thev shed at every fourth pick of the loom and remain there for only one pick after which they are returned to the shed b within which they remain for three successive picks before they are again raised into shed a.v ln this way asthe two fabrics F and are woventhey) are tied together longitudinally, not only etween the roving or. sliverV adding-strands 5, but at each selvage 6' a so as will be clear from Figs. 2 and 3. A Y

ln order to draw the two fabrics Fand B together between the padding strands 5 and at the selvages 6, the stitching warps 2*l may besupplied from a separate warp beam under sufficient tension other than is main- 1 and 2, so that the exterior of the finished padded fabric has a quilted or corrugated Shape and appearance. Y Y

AThe padding stra ds 5 may be led from the supply into position between the two sets of warps 1 and 2, past the harnesses and reel specially constructed or arranged to permit of this, and so as to the'. fabric as it is produced, each strand .occupying a tubular compartment of its own formed in the fabric by the tie warps 2" which are raised and lowered from one shed to the other through the spaces between said strands 5. i

ln Fig. 5 I- have shown a modified structure which differs from that valready described only in the provision or" two sets of tie warps 2b and 2c which are simultaneously but .oppositely shifted from one shed to the/other every secondpick of the loom.

V`When my fabric is to be made into a garment, and it is desired to have the outside of one color or character and the inside of another color or character, thisrequirement the weft thread 3 Y Y Y be incorporated in I may be met by employing threads land 3 of a color or character appropriate to the outside of the garment and. threads 2 and ploying tie Warps 2, or 2b and 2C, of tlie same colorer character as the threads and 3 of the outside fabric. in this Way the Warps which are incorporated inthe outside of the garment same color or character as the latter.

The strands 5. if composed of such loosely I employ the term roving7 herein for the purpose of description and not of limitation; that is, the term is intended to apply to any strands of loose fluffy material Whether known by the specific terms reves, slivers or strips cut from batting, or strands of any material which will provide lling or stuling between the two Woven fabrics. Nor do l limit myself tolany such proportions as indicated in the Width, or greater relative thickness, than illustrated, and the 'tie warps may pass through at greater or lesser intervals.

quiring any sewing other than to hem or otherwise nish the cut edges,the fabric can be readily cut according to patterns for the making of vests7 coat linings, or other ap parel uses,-or to provide absorbent pads. My improved fabric is especially adapted rawings; for instance the roving may be. of greater relative geraete to the last mentioned use, Where expedition 's often required in the preparation of a pad becausev apadef the'desired size'can bey quickly cut from a sheet of Ythe material-- kept in stock Without risk ofthe soft filling.'

becoming displaced. And all thel'cutting re-'j strips of soft, Hufiy material incorporatedv therein during the process of Weaving and having binding Warps uniting the fabrics between the said strips. Y

Sheet material formed of two fabrics '-.voVen-simultaneously and having parallel strips of soft, fluffy material incorporated' therein during the process of Weaving and having binding warps uniting the fabrics between the said strips and reinforcing threads extending longitudinally of thev strips of soft, liuiiy material. y

3. rThe method of terial, consisting in simultaneously Weaving two fabrics2 introducing soft, fluffy material between said two fabrics, and uniting the two fabi-ics by binding Warps during the processof weaving said fabrics.
