In manufacturing a reversible carpet of this class according to the
present invention, the pattern is formed by means of the warp and weft
combined, and any suitable ingrain warp operated by the harness or
jacquard of the loom may be used. In combination with ingrain warp, a
fine catching or binding warp, operated by the gear or jacquard
harness of the loom, is employed, such fine catching warp being used
to bind the weft into the fabric, therefore, if the fabric be woven
two-ply, the ingrain warps are thrown on both the under and upper
surfaces of the fabric, as well as in between the weft, according to
the pattern being woven, by which means four colors are shown on both
sides of the fabric, two being produced by the weft, and two by the
ingrain warps. More than four colors, however, can be produced upon
each side by multiplying the number of colored wefts and warps
employed. If the fabric woven be a three-ply, with the addition of the
ingrain warps thrown on each face of the fabric, then five or more
colors would be imparted to the carpet, as any number of colors can be
used to form a given pattern, by planting or arranging the colors in
the warp, and the remaining colors by the wefts, and so on. The
ingrain warp thread, therefore, together with the weft, used as stated
above, produces an effective pattern on both sides of the carpet;
consequently, it becomes reversible, and this can be accomplished
whether the carpet woven be two, three, or other number of ply. By
reference to the accompanying sheets of drawings, this invention will
be better understood. Fig. 1 is an enlarged cross section of an
improved carpet, a three-ply, that is to say, it is a carpet wherein
three shuttles are employed, each carrying a differently colored weft;
a represents the weft threads which may be composed of any suitable
fiber, b and c are cotton or other fine warp threads, which are
employed for binding the weft together, while d and e represent the
ingrain or woolen warp, where it will be seen that each ingrain warp,
