THE MANUFACTURE OF WATERPROOF GARMENTS
Year: 1870

page_text: LETTERS PATENT to Charles Montagu, of Cannon Street, in the
"IMPROVEMENTS
City of London, Manufacturer, for the Invention of
IN THE MANUFACTURE OF WATERPROOF GARMENTS."
Scaled the 4th October 1870, and dated the 7th April 1870.
PROVISIONAL SPECIFICATION left by the said Charles Montagu at the
Office of the Commissioners of Patents, with his Petition, on the
7th April 1870.
I, CHARLES MONTAGU, of Cannon Street, in the City of London,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF GARMENTS," to be as
follows:-
This Invention relates to the manufacture of what are usually called
waterproof overcoats and other waterproof garments. These garments
have hitherto been made of combined materials, that is to say, of some
textile fabric on the surface of which is applied by solution, cementing,
or other means a coating, covering, lining, or surface of india-rubber,
or other similar waterproof material.
Now the object of my Invention is to manufacture a waterproof
garment in an improved manner so as to render it suitable for wearers
of different dimensions, and to obtain a durable or friction resistent
garment.

page_text: For this purpose, according to my Invention, I employ sheet vulcanized
caoutchouc, but I do not combine the same with nor apply the same to
a garment, surface, lining, or width of textile or other fabric, no other
material whatever being used in the manufacture of my overcoat or
garment than sheet vulcanized caoutchouc except for buttons or such
like appurtenances or appendages.
The Invention may thus be performed:-I form caoutchouc into
sheets by rolling, or form it into masses or blocks, afterwards cut into
sheets or reduced by solvents to a dough-like condition, and then spread
it into sheets which are afterwards vulcanized by any ordinary process.
I then by properly shaped patterns cut the vulcanized caoutchouc
sheets to a proper size and shape for producing the required garment,
and cement the parts of the same together at the part or parts required.
Sometimes two or more thicknesses of the material may be used.
When button holes or pockets are needed these can be cut in the
garment, and the gussets, flaps, or pockets are cemented to the body
of the garment as necessary.
non-
Sometimes instead of using vulcanized caoutchouc, I use
vulcanized or semi-vulcanized caoutchouc, or caoutchouc vulcanized
by the sine-calore process.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Montagu in the Great Seal Patent Office
on the 7th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
MONTAGU, of Cannon Street, in the City of London, Manufacturer, send 2
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of April, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, givea
and grant unto me, the said Charles Montagu, Her special licence
that I, the said Charles Montagu, my executors, administrators, and
assigns, or such others as I, the said Charles Montagu, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term

page_text: therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF WATERPROOF GARMENTS," upon the condition (amongst
others) that I, the said Charles Montagu, my exccutors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Charles Montagu, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention relates to the manufacture of what are usually called
waterproof overcoats and other waterproof garments. These garments
have hitherto been made of combined materials, that is to say, of some
textile fabric on the surface of which is applied a solution, dough coating,
covering, lining, or surface of india-rubber or its compounds, or other
similar waterproof material.
Now the object of my Invention is to manufacture a waterproof
garment in an improved manner so as to render it suitable for wearers
of different dimensions, and to obtain a durable or friction resistant
garment.
For this purpose, according to my Invention, I employ sheet vulcanized
caoutchouc, but I do not combine the same with nor apply the same to
a garment, surface, lining, or width of textile fabric as heretofore; but
according to my Invention I manufacture an overcoat or other water-
O proof garment of sheet vulcanized caoutchouc alone, no material what-
ever being used in the manufacture of such overcoat or garment other
than sheet vulcanized caoutchouc except for buttons or such like appur-
tenances or appendages.
The Invention may be best practically performed in the following
manner :-I take the caoutchouc, and by ordinary process I form it into
sheets by rolling, or into masses or blocks which I afterwards cut into
sheets or reduce by solvents to a dough-like condition, and then spread
it into sheets, which are afterwards vulcanized by any ordinary process.

page_text: I then by properly shaped patterns cut the vulcanized caoutchouc sheets
to a proper size and shape for producing the required garment, and I
cement the parts of the same together at the part or parts required.
Sometimes two or more thicknesses of the caoutchouc material may be
used.
When button holes or pockets are needed, these can be cut in the
garment, and the gussets, flaps, or pockets are cemented to the body of
the garment as necessary.
Sometimes instead of using vulcanized caoutchouc in carrying out my
Invention, I use non-vulcanized or semi-vulcanized caoutchouc, or
caoutchouc vulcanized, partially vulcanized, or treated by the sine-
calore process.
When buttons or like appendages or appurtenances are used, these
may be made of any ordinary material and attached to the caoutchouc
garment in the manner usual in attaching such articles to waterproof
garments.
Having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim the manu-
facture of waterproof garments, substantially as herein-before described,
according to which the garment is made of caoutchouc whether vul-
canized, semi-vulcanized, or non-vulcanized (or partially vulcanized
(or treated) by the sine-calore process), and without combination with
textile fabric or any other material, except for the buttons and like
appendages.
In witness whereof, I, the said Charles Montagu, have hercunto
set my hand and seal, this Sixth day of October, in the year
One thousand eight hundred and seventy.
Witness,
