vention of "IMPROVEMENTS IN THE MANUFACTURE AND PREPARATION OF

ALBERT COOPER, of 80, Gloucester Road, in the Parish of Saint Mary Abbotts,
Kensington, in the Counter of Middlesex. "IMPROVEMENTS IN THE MANUFACTURE
AND PREPARATION OF COUNTER IRRITANTS IN LIEU OF ORDINARY MUSTARD
PLAISTERS, MUSTARD PAPER, OR OTHER SINAPISMS."
I take cloth of any kind or any suitable textile fabric, or when preferred I use
felt or leather and render these or any of them more or less impervious to moisture
either by waxing or by other means; or they may be preferably made waterproof
by the application of a solution of india-rubber or gutta percha. A suitable
preparation of mustard is then applied to either side; or in lieu of the preparation
of mustard I apply any known preparation of mustard or compounds containing the
active principles of mustard, whether combined with other substances or not, which
are suitable for medicinal application to the skin for the purpose of producing
counter irritation; but I prefer to apply to the cloth or textile fabric, felt, or leather,
a solution of india-rubber or gutta percha, and then instead of the ordinary
preparation of mustard I make use of the mustard compound already known as
sinapine which has hitherto been spread on thin paper.
Among other advantages of using cloth or textile fabric, felt, or leather made more
or less impervious to moisture, or waterproofed with india-rubber or gutta percha,
instead of paper or other substances or fabrics through which moisture may
evaporate on the application of the preparation of mustard or other counter irritants
to the skin may be mentioned the retention of moisture and warmth, and con-
sequently an emollient poultice-like action in addition to the counter irritation
produced, greater case of producing and certainty of attaining the desired result, and
the capability of using the counter irritant so prepared several times.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by tho
said Albert Cooper in the Great Scal Patent Office on the 29th September
1876.
ALBERT COOPER, of 80, Gloucester Road, in the Parish of Saint Mary Abbotts,
Kensington, in the County of Middlesex, Chemist. "IMPROVEMENTS IN THE
MANUFACTURE AND PREPARATION OF COUNTER IRRITANTS IN LIEU OF ORDINARY
MUSTARD PLAISTERS, MUSTARD PAPER, OR OTHER SINAPISMS."
This Invention consists in the manufacture of an improved form of mustard
plaister which I intend designating "Cooper's Compound Mustard Cloth."
The object of this Invention is an improvement in the manufacture and
preparation of counter irritants suitable for medicinal application to the skin in
lieu of ordinary mustard plaisters, mustard paper, or other sinapisms, by which
mustard poultices or plaisters, compound preparations of mustard with other
suitable ingredients, and particularly the compound preparation already known as
sinapine, may be applied to cloth of any kind or any suitable textile fabric; or when
preferred any such counter irritants, such as mustard or any compound preparations
thereof or sinapine may be applied to felt or leather, so as to form a stronger and
more flexible means of using such counter irritants or sinapisms than when applied
to paper, and in a more convenient form than when a common mustard plaister has
to be prepared whenever required for use.
My Invention consists chiefly in the application or spreading of any known
materials used as counter irritants in lieu of mustard plaisters, such as mustard,
compounds of mustard with other suitable ingredients, and the preparation known
as sinapine upon cloth of any kind or any suitable textile fabric, or felt, or leather.
I prefer to make more or less impervious to moisture any kind of cloth used or any
textile fabric found suitable, or the felt or leather. For this purpose I either wax
the cloth or other fabric, felt, or leather, or I apply solutions of india-rubber or
gutta percha, or any other waterproofing solution or material; or I combine by
pressure or any other means of causing adhesion a thin sheet of waterproof material,
such as india-rubber or gutta percha, or another cloth or textile fabric which has
been previously rendered more or less impervious to moisture. A suitable
preparation of mustard, or a compound preparation of mustard with other suitable
ingredients, or the preparation known as sinapine, is then spread or brushed on to
either side of the cloth or textile fabric, or on to the felt or leather, whether the
cloth or textile fabric or felt or leather is or is not rendered more or less waterproof
by any of the means before-described, or such as may be preferred as most
suitable.
The preparation of mustard or compound preparation of mustard containing
other ingredients, or the preparation known as sinapine, may be applied in a liquid
form, and afterwards be allowed to dry or be dried by any convenient means; or a
moist adhesive mixture may be first applied to the cloth or textile fabric, or felt or
leather, whether rendered more or less impervious to moisture or not, and then the
preparation of mustard or compound preparation of mustard, or the preparation
known as sinapine may be applied in a more or less solid condition or quite dry,
and may remain affixed to the cloth or textile fabrics, or felt, or leather, either in a
moist or partially moist form, or in a more or less dry or completely dry form.
The method I prefer for carrying out my Invention is to take a piece of calico
or linen, and affix by pressure or otherwise a thin sheet of india-rubber, or apply a
solution of india-rubber to one side and then apply in a moist condition a
preparation of mustard or compound preparation of mustard with other suitable
ingredients, or the preparation known as sinapine, and dry these or any of these
preparations on the other side of the linen or calico.
Among other advantages of using cloth or textile fabric, felt, or leather, made
more or less impervious to moisture, or waterproofed with india-rubber or gutta
percha, instead of paper or other substances or fabrics through which moisture may

page_text: evaporate on the application of the preparation of mustard or other counter irritant
to the skin may be mentioned the retention of moisture and warmth, and con-
sequently an emollient poultice-like action in addition to the counter irritation
produced, greater case of producing and certainty of attaining the desired result,
and the capability of using the counter irritant so prepared several times.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into
practical effect, I claim as my Invention the manufacture of an improvement in
counter irritants suitable for medicinal application to the skin, in which any
preparation of mustard or compound preparation of mustard with other suitable
ingredients, or the preparation known as sinapine, are applied to any kind of cloth
or textile fabric, or felt, or leather in lieu of the ordinary mustard plaister or
mustard paper, or any other known sinapisms, whether the cloth or textile fabric,
or felt, or leather, be rendered by any means more or less impervious to moisture,
and whether the mustard preparation or compound preparation of mustard with
other suitable ingredients, or the preparation known as sinapine, be kept for use in
a more or less moist or dry condition, or whether it be practically dry.
In witness whereof, I, the said Albert Cooper, have hereunto set my hand and
seal, this Twenty-ninth day of September, in the year of our Lord One
thousand eight hundred and seventy-six.
