delphia Pennsylvania, United States of America do hereby declare the nature of
our said Invention for “IMPROVEMENTS IN THE MANufacture of Pile Fabrics
to be as follows:-
39
The object of our Invention is to facilitate the production of plushes, velvets, or
other pile fabrics, whether the pile be cut or uncut, and this object we attain in the
following manner.
We use instead of the loom commonly used for weaving pile fabrics, an ordinary
box loom, and instead of forming the pile warps into loops in the usual manner by
the aid of wires, we use in place of the latter, a weft or filling thread or threads of
a size dependent upon the desired size of the loops to be produced on the fabric,
these threads being in addition to the usual warp and weft threads required for the
backing fabric.
All of the threads of the fabric with the exception of the thick filling threads
above referred to should be of silk, wool, or other animal fibre capable of resisting
the action of agents, to the destructive effects of which the threads of vegetable
fibre will yield.
The woven fabric is subjected to the action of bydrochloric acid sulphuric acid,
hydrochloric acid gas or other agent which will destroy the vegetable fibre so that
the fabric will be in the condition of ordinary pile fabric from which the wires for
the formation of the loops have been removed.
Pile fabrics can thus be manufactured in accordance with our Invention at a
much more rapid rate than when pile wires are used, this rapidity of manufacture
much more than compensating for the cost of the thick filling thread and the agent
for destroying the same.
Our Invention is alike applicable to the production of plain or figured pile
fabrics and the pile loops can be sheared in the same manner as those of an
ordinary pile fabric when a cut pile is desired.
Although we have described the use of thick weft threads as a medium for the
formation of pile loops in the warp it will be evident that a reverse arrangement

vegetable fibre may be in the warp, and the pile loops may be formed of the weft,
the cotton warp threads being afterwards destroyed.

COMPLETE SPECIFICATION.
We EDWARD SCHEPPERS Manufacturer of Textile Fabrics and EMILE SCHEPPERS
Manufacturer of Textile Fabrics both of American and Diamond Streets
Philadelphia Pennsylvania, United States of America do hereby declare the nature
of our invention for "IMPROVEMENTS IN THE MANUFACTURE OF PILE FABRICS,"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of our Invention is to facilitate the production of plushes, velvets or
other pile fabrics whether the pile be cut or uncut; and this object we obtain in the
following manner.
We use instead of the loom commonly used for weaving pile fabrics, an ordinary
box loom and instead of forming the pile warps into loops in the usual manner by
the aid of wires, we use in place of the latter, a weft or filling thread or threads of
a size dependent upon the desired size of the loops to be produced on the fabric
these threads being in addition to the usual warp and weft threads required for the
backing fabric.
All the threads of the fabric with the exception of the thick filling threads above
referred to, should be of silk, wool, or other animal fibre capable of resisting the
action of agents, to the destructive effects of which the threads of vegetable fibre
will yield.
The woven fabric is subjected to the action of hydrochloric acid, sulphuric acid,
hydrochloric acid gas, or other agent which will destroy the vegetable fibre, so that
the fabric will be in the condition of ordinary pile fabric, from which the wires for
the formation of the loops have been removed.
Pile fabrics can thus be manufactured in accordance with our invention, at a
much more rapid rate than when pile wires are used, this rapidity of manufacture
much more than compensating for the cost of the thick filling thread, and the
agent for destroying the same.

page_text: Our Invention is alike applicable to the production of plain or figured pile
fabrics, and the pile loops can be sheared in the same manner as those of an
ordinary pile fabric, when a cut pile is desired.
Although we have described the use of thick weft threads as a medium for the
formation of pile loops in the warp, it will be evident that a reverse arrangement
will be equally effective, that is to say, the thick threads of cotton or other
vegetable fibre may be in the warp, and the pile loops may be formed of the weſt,
the cotton warp threads being afterwards destroyed.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
The method or process herein before described of making pile fabrics consisting
In employing for the loops and binding threads, silk, wool or other animal fibre,
and interweaving therewith threads of cotten or other vegetable fibre, either in
weft or warp, as fillers for the loops, and then subjecting the fabric to agents which
will destroy the said threads of vegetable fibre and leave intact the fabric and its
loops composed of threads of animal fibre.
Dated this 11th day of May 1885.

Agent for the said Edward Scheppers
and Emile Scheppers.
