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 climato
but particularly hot climates.
The object of our invention is to make the garments free from the ordinary dis-
agreeable 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 partially vulcanized in a dry air heated stove at a low vulcanizing temperature
for a short time.
Then 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 for the time found requisite
to drive off the odour and completely vulcanize, the heat being a little greater than
was employed in the first process of vulcanization the result being that the garments
are vulcanized and deodorized at the same operation.
.
When this latter process is finished the garments are odourless or free from dis-
agreeable 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 tho
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 same is to
be performed, 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
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.

page_text: The object of our invention is to make the garments free from the ordinary dis-
agreeable 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.
The proportions of the materials and mode of mixing the dough compounds above
referred to and spreading or applying them to the fabric, is well known to the trade,
and the materials may be mixed in the ordinary manner, and the proportions varied
as required, and in some cases whiting or equivalent material may be added.
Farina or similar material is applied to the proofed surface after the proofing in a
well known manner used for making farina coated rubber waterproof goods, and the
fabric is then partially vulcanized in a dry air heated stove (which stoves are well
known to the trade) at a vulcanizing temperature say, about 250 degrees Fah., for a
short time.
The garments are made in the ordinary manner from the fabrics prepared as above
described, the seams being cemented or secured together by what is known as the
"ordinary solution" which has no sulphur in it, but when preferred we use a solution
which will vulcanize.
Then the garments are hung up in a dry air heated stove for the time found requisite
to drive off the odour, sufficient heated air being permitted to escape from the upper
part of the stove during the process to carry away the volatile vapour containing the
disagreeable odour, and completely vulcanize the garments; the heat being a little
greater (say about 260 degrees Fah.) than was employed in the first process of
vulcanization, the result being that the garments are thus completely vulcanized
and deodorized at the same operation.
When this latter process is finished the garments are odourless or free from dis-
agreeable smell and may be perfumed if desired, by placing the oil of some volatile
perfume such as oil of Lavender or other scent giving material in the stove for a
short time, at the end of the process without permitting the heated air to escape
therefrom.
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 manufacture of india rubber waterproof garments free from disagreeable 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.
