REVERSIBLE FABRICS,"
"
In the ordinary method of weaving reversible fabrics it is customary to form the
face and back of the cloth with alternate picks, the face being formed with one
pick and the back by the next pick.
These improvements have for their object the simultaneous formation of both
the back and face of the cloth or fabric with the same pick, and at the same time
to make back and faco exactly alike without a broken appearance, with no part of
the weft hidden, and free from the thick and thin places at present usually found
near the edges of such fabrics.
For this purpose we float the weft alternately over and under three or more
threads, missing one warp end in each succeeding pick. The following example is
given as a type, the number of threads selected being a convenient one in
practice:
First pick, float over four and under four alternately.
Second pick, over one then under and over four alternately, as in the first pick.
Third pick, under two then over and under four, as before.
Fourth pick, over three then under and over four, as in previous picks.
Fifth pick, under four and over four alternately.
Sixth pick, under one then over and under four, as before.
Seventh pick, over two then under and over four alternately.
Eighth pick, under three then over and under four alternately.
The above series of picks is then repeated.
Fabrics woven as above described are even and alike on both sides, and have
a full and soft feel, and are especially suitable for printings, raisings, and other
finishes.

ABRAHAM ROTHWELL and CHARLES HENRY ROTHWELL, both of Bury, in the
County of Lancaster, Mill Managers. "IMPROVEMENTS IN WEAVING REVERSIBLE
FABRICS."
In the ordinary method of weaving reversible fabrics it is customary to make one
pick for the face of the cloth, and the next pick for the back. The object of our
Invention is to make the face and back of the cloth exactly alike with the same
pick, and in such a manner that no part of the weft is hidden, that neither face
nor back shall have a broken appearance, and that there shall be no thick and
thin places such as are commonly found near the selvedges of cloth woven in the
ordinary manner.
Our improvements consist in floating the weft alternately over and under three
or more threads, missing one warp end in each succeeding pick, in the following
manner:
The first pick floats or passes over four and under four ends.
The second pick passes over one, under four, and over three.
The third pick passes under two, over four, and under two.
The fourth pick passes over three, under four, and over one.
The fifth pick passes under four and over four.
The sixth pick passes under one, over four, and under three.
The seventh pick passes over two, under four, and over two.
The eighth pick passes under three, over four, and under one.
the round.
This completes
We have selected four threads in the typical example given above, and illustrated
the same on the accompanying diagram, as it is a convenient one in practice, but
our improvement may be applied to any cloth floating three or more threads.
Having now described the nature of this our said Invention, and the manner
in which the same is to be performed, we wish it to be understood that we do not
confine ourselves to the example hereinbefore given and illustrated on the accom-
panying diagram, and that what we claim is,-
The manufacture or weaving of reversible fabrics, as and for the purposes
hereinbefore described and illustrated on the accompanying diagram.
In witness whereof, I, the said Charles Henry Rothwell, for and on behalf of
the said Abraham Rothwell and myself, have hereunto set my hand and
seal, this Twenty seventh day of April, in the year of our Lord One
thousand eight hundred and eighty one.
