CARPET FABRIC.

SPECIFICATION forming part of Letters Patent No. 363,366, dated May 24, 1887. Application filed February 19, 1886. Serial No. 192,533. (Specimens) Massachusetts, have invented an Improvement in Carpet Fabrics, of which the following description, in connection with the accompanying drawings, is a specification, likeletters 011 the drawings representing like parts.

This invention has for its object the production of a double-faced ribbed carpet fabric, either side of which may be used uppermost, both faces exhibiting a pattern showing warpthreads of three or more colors.

My improved carpet fabric is composed of figuring-warps, binder-warps, and stuffer and binder wefts, the stuffer-weft larger than the binder-weft, and cooperating with the figur-- ing-warps, serving to give the fabric a ribbed appearance, like a pile fabric. I

Myinvention consists in a carpet fabric composed of three or more sets of figuring-warps, aset of binder-warps, and stuffer and binder weft, two sets of the figuring-warps appearing on the two faces of the fabric to form each of the ribs, such sets being formed from portions of three or more sets of warpthreads, the threads of that set of warps which do not appear at one or the other face of the fabric when the staffer-warp is being inserted being retained at the center of the fabric between the stuffer-weft of the opposite sides, so as to 0011- stitute a body for the fabric.

Figure l is a longitudinal section, on an en larged scale, of acarpet fabric embodying my invention, and Fig. 2 a plan view of a part of the carpet with the warp and weft spread out to show their crossing.

My improved carpet fabric consists, essentially, of three or more sets of figuring-warps, a b c, a binder-warp, d, a staffer-weft, c, and a binder-weft, f. Each set of warps a b 0 may be of a separate color, or be party-colored, or be striped in the chain.

' To produce my improved fabric I may make use of any ordinary two-shuttle Jacquard loom, well known in the art to which my invention relates, it having usual harness or cords to receive the figuring-warps, and usual means such as a comber-board or griffsto raise and lower the harness or cords in proper order or sequence, in accordance with the demands of the patterncards carried by the usual patterncylinder.

One jacquard which may be employed to advantage in the manipulation of the figuringwarps in the production of my improved carpet fabric is described in United States Patent No. 230,591, dated July 27, 1880.

To move the binder-warp I prefer to our ploy a harnessframe having usual heddles, the said harness-frame being operated through any of the well-known instrumentalities deriving their movement from, say, a cam on the picker-shaft.

By means of the jacquard either of the said figuring-warps may be made to appear at either face or side of the carpet, as desired, preparatory to inserting the staffer-weft c. The binderwarp will preferably be controlled by one harnessframe.

The binder-warp will pass from one to the other face or side of the fabric, and be there locked by a shot of binder-weft, f. Herein I have shown two picks of stuffer-weft as followed by two picks of binder-weft.

Referring to the left-hand end of Fig. 1, the figuring-warp a is shown as exposed at the upper side of the fabric for two picks of the stutter-weft. Then the said Warp is thrown to the under side of the fabric for one-pick of the stuffer-weft, and thereafter for two picks of the stuffer-weft, taking into consideration but one side of the fabric, the said warp remaining concealed in the fabric, appearing again, however, at the upper side of the fabric. for, as herein shown, three picks.

The figuring-warp 1), commencing at theleft of Fig. 1, is down at the under side of the fab-- ric for two picks of the staffer-weft at that side, then remains in the fabric for one pick of staffer-weft at each side of the fabric, and then passes to the upper side of the fabric, where it remains for one pick of staffer-weft, and then passes to the under side of the fabric for another pick of stuffer-weft, and thereafter, as herein sl1ow11,-the warp 6 remains concealed in the fabric and does not appear at either side thereof.

The figuring-warp 0, commencing at the left of 1, is concealed while three picks of of the fabric, and then the said warp is brought.

stuffer-weft are introduced at the upper side to the upper side of the fabric for one pick of stutter-weft at that side, and then the said Warp is carried to the under side of the said fabric for three picks of the stuffer-weft at that side, when the said warp is again carried into the center of the fabric and concealed.

The binder-warp is made to appear uniformly first at the under and then at the upper side of the fabric, and the said warp is caught and held by the binder-weft, the said binder warp and weft completing the integrity of the fabric, and being the only threads that are interlocked uniformly.

By inspecting the drawings it will be seen that either one'of the three sets of figuring- Warps may be made to appear at either side of the fabric for one or more picks of stufferweft, or be concealed in the center of the fabric, and with three sets of figuringwarpaeach controlled by usual Jacquard harness, it is possible to make a fabric in which three colors may be made to appear in pattern at every pick of staffer-Weft at both the upper and under side of the fabric, it being assumed that all the warps of each set are of the same color.

If each set of figuring-warps were held by one harness-frame of any ordinary fancy loom, and all the warps of one color be moved together, then all the threads raised or lowered for any one pick of staffer-weft would be of vention to leaving any particular warp-thread up or down for any particular number of picks, as that will depend upon the pattern being woven or produced by the warps of different color.

The essential feature of my invention is that some of the threads of any set may be made to appear and to figure the upper and the lower side of the fabric at any pick.

It is obvious that I'may employ more than three sets of warps in proper Jacquard harness, and gain in the number of colors that may be made to appear in the carpet to produce the pattern.

I claim-- The hereindescribed carpet fabric, composed of three or more sets of figuring-warps, one single set of binder-warp, and a stutter and a binder weft, two of said sets of figuringwarps being made to appear at intervals at both the upper and under sides of the said fabric, the set or sets of figuring-warps not appearing at either surface of the fabric for one or more picks being buried in the body of the fabric, both surfaces of the fabric presenting ribs formed by the loops of warp-thread filled by the stuffer weft, all substantially as described.

In testimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.

GEO. CROMPTON.
