I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF FABRICS SUITABLE FOR CARPETS, HANG-
INGS, FURNITURE STUFFS, AND THE LIKE," (a communication from abroad by
Bernard Landwerlin; of Dornach, near Mulhouse, and Theodore Dopff, of
Mulhouse, France,) to be as follows:-
The object of this Invention is the manufacture of 'stuff's such as carpets,
hangings, curtains, draperies, and the like with the pattern on both sides, or
with the pattern on one side only and a back, and the Invention is carried into
effect by the employment of two machines, 'a chénille machine and a loom,
as hereafter described:
The pattern to be produced on the 'fabric is divided into squares of a
suitable size according to the degree of 'fineness required in the work: The
number of colors composing the design. being known, and each color being
numbered, the pattern is read, this reading consists in noting upon a list each!
square, and designating it by its number, commencing at the left for the first
line, and the right for the second, and so on, preserving this order for a
certain distance according to the length of the chenille machine. By con-
tinuing in this manner to the end of the pattern a number of lists are pro-
duced which will be greater or less according to the repeat (raccord) of the
pattern. Each of these lists then will give as many of the figures as there

page_text: are squares of color, these figures corresponding to the figures dyed of the
same color. Each of these lists serves as a pattern to the workman for
manufacturing the chenille in wool, silk, or other material. This is the first
operation.
According to the breadth of the chenille frame will the workman produce
the same chenille a greater or less number of times, let us suppose twenty;
the first part of the pattern would be produced twenty times in a state of
multi-colored chenilles, the same for the second part, and so on to the last, the
complete pattern will then be produced twenty times.
To produce a fabric with a pattern on both sides upon an ordinary loom, form
a warp of fine silk, linen, or other thread passing through two heddles crossing
each other, and weave with the chenille before described. If the weaving is
effected alternately with the chenille and twist (cordonnet), the same result
will be produced with a great economy of material.
To produce a fabric with a back or pattern on one side only different means
may be adopted. The following will serve as an example:-The warp is
förmed of fine threads and of twist, two heddles for the fine threads as before,
and two heddles for the twists. The first throw is the chenille, which becomes
united by the action of the two fine thread heddles. The second throw, which
is the twist, is united by the fine thread and ties at the same time the twist
of the warp. Glass beads or other ornaments may be thrown into the chenille
to form a pattern.. Fabrics are also manufactured according to this Invention
by making use of the chenille as a warp by working in the reverse manner to
that before described. In both cases, but especially in the latter, flat or
untwisted chenilles may be employed instead of round or twisted chenilles..
If the fabric is required to be of a great thickness, the flat chenille must be
made of the desired height in such manner that when it is in position in the
loom, it will determine the thickness. For example:-For carpets and rugs,
the chenille is cut much thicker than for most other fabrics.
This Invention allows of a pattern being produced of the whole length and
breadth of the piece, that is to say, of a single. repeat without more expense,
excepting that of the first cost of the pattern, than where the pattern is com-
posed of several repeats. For some descriptions of fabrics, chenille made
upon a wire foundation may be used.
