Improvements in the Manufacture of India-rubber Waterproof
Garments.
We, GOODMAN CHARLES MANDLEBERG, HENRY LESSER ROTHBAND and SAMUEL
LAWRENCE MANDLEBERG, of the Albion Rubber Works, Pendleton, Manchester, in the
County of Lancaster, Manufacturers of India Rubber Piece and other Goods, do hereby
declare the nature of the said invention, to be as follows:-
Our invention relates to india rubber waterproof garments made from the finer and
more delicate single texture india rubber waterproof fabrics which are intended to
be used more especially for "Ladies' Waterproofs "to be suitable for wear in any climate
but particularly hot climates.
The object of our invention is to make the garments free from the ordinary
disagreeable odour unpleasant both to the wearer and to others, and we carry out
our invention by spreading or proofing a suitable fabric such as cotton, wool or
silk or a mixture of these fibres with several coats of proofing such as those hereinafter
mentioned.
The first coat is with a dough formed of india rubber Litharge and Naphtha solvent,
the succeeding coats of proofing (of which about three should be applied) are from
a dough compound of rubber Litharge and Sulphur and Naphtha solvent, then a
last coat or two of proofing is applied like the first but with a smaller proportion
of Litharge.
Then farina or similar material is applied to the proofed surface and the fabric is
then fully vulcanized in a dry air heated stovė.
Then the fabric vulcanized by the dry heat process as above stated is "semi cured"
i.e. the surface is hardened by treating the fabric with the well known liquid or cold
process of vulcanization by a weak liquid which will sufficiently harden the surface.
Or this hardening of the surface may be effected by the introduction of the well
known vapour process of vulcanization.
The garments are made in the ordinary manner from the fabrics prepared as above
described, the seams being secured by what is known as the "ordinary solution"
which has no sulphur in it.
Then the garments are hung up in a dry air heated stove, heated to a temperature
ordinarily of about 200 degrees Fah. for the time found requisite to drive off the.
odour.
When this latter process is finished the garments are odourless or free from disagree-
able smell and may be perfumed if desired by placing the oil of some volatile perfume
such as oil of lavender in the stove for a short time at the end of the process.

Improvements in the Manufacture of India-rubber Waterproof
Garments.
We, GOODMAN CHARLES MANDLEBERG, HENRY LESSER ROTHBAND, and SAMUEL
LAWRENCE MANDLEBERG, of the Albion Rubber Works, Pendleton, Manchester, in the
County of Lancaster, Manufacturers of India Rubber Piece and other Goods, do hereby
declare the nature of this invention and in what manner the sanie is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
Our invention relates to india rubber waterproof garments made from the finer and

page_text: more delicate single texture india rubber waterproof fabrics, which are intended to be
used more especially for "Ladies' Waterproofs" to be suitable for wear in any climate
but particularly hot climates.
The object of our invention is to make the garments free from the ordinary
disagreeable odour unpleasant both to the wearer and to others, and we carry out
our invention by spreading or proofing a suitable fabric such as cotton, wool or silk
or, a mixture of these fibres with several coats of proofing such as those hereinafter
mentioned.
.t
The first coat consists of an application of a dough formed of india rubber, Litharge,
Sulphur and Naphtha Solvent, the succeeding coats of proofing (of which about
three should be applied) are also formed of a dough compound of rubber, Litharge,
Sulphur and Naphila Solvent, but with a little more sulphur in the dough, than is
used for the first coat, then a last coat or two of proofing is applied like the first but
without sulphur in the dough.
The proportions of the materials and mode of mixing the dough compounds above
referred to and spreading them upon the fabric is well known to the trade, and the
materials may be mixed in the ordinary manner, and the proportions varied as
required.
After preparing the fabric as above described farina or similar material is applied
to the proofed surface and the fabric is then fully vulcanized in a dry air heated stove at
a temperature of about 250 degrees Fah., the fabric vulcanized by the dry heat process
as above stated is then "semi-cured," ie., the surface is hardened by treating the
fabric with the well known liquid or cold process of vulcanization by a weak liquid
which will sufficiently harden the surface.
Or this hardening of the surface may be effected by the introduction of the well
known vapour process of vulcanization, or other known means of hardening the surface
may be employed to facilitate the making up of the prepared cloth into garments.
The garments are made in the ordinary manner from the fabrics prepared as above
described, the seams being secured by what is known as the "ordinary solution"
which has no sulphur in it.
Then the garments are hung up in a dry air heated stove, heated to a temperature
ordinarily of about 200 degrees Fah. for the time found requisite to drive off the
odour.
When this latter process is finished the garments are practically odourless or free
from disagreeable smell and may be perfumed, if desired by placing the oil of some
volatile perfume. such as oil of lavender in the stove for a short time at the end of
the process.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
The manufacture of india rubber waterproof garments practically free from disagree-
able odour and scented with an agreeable perfume when required by preparing the
cloth or fabric and making it into garments by the process or processes substantially
as herein before described.
