IM- BRAVEMENTS IN THE MANUFACTURE OF WATERPROOR FARRICS
Year: 1853

page_text: LETTERS PATENT to Charles Goodyear, of Avenue Road, St. John's
Wood, in the County of Middlesex, for the Invention of "IM-
BRAVEMENTS IN THE MANUFACTURE OF WATERPROOR FARRICS"
Sealed the 7th December 1853, and dated the 30th August 1853.
PROVISIONAL SPECIFICATION left by the said Charles Goodyear
at the Office of the Commissioners of Patents, with his-Petition,
on the 30th August 1853.
I, CHARLES GOODYEAR, of Avenue Road, St. John's Wood, in the
County of Middlesex, do hereby declare the nature of the Invention
for IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF FABRICS" to be
as follows:-
This Invention relates to waterproof fabrics made of fibres, and.
cemented together by means of india-rubber cement. Heretofore in
making such fabrics it has been usual to employ india-rubber dissolved
in a suitable solvent, without other matters being mixed therewith.
Now the present Invention consists of mixing like fibres to those of
which the fabric is composed with the dissolved india-rubber, and then
to use it in like manner to that in which the simple solution of india-
rubber has been used, by which means the fibres mixed with the

filed by the said Charles Goodyear in the Great Seal Patent
Office, on the 23rd February 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
CHARLES GOODYEAR, of Avenue Road, Saint John's Wood, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of August, in the year
cf our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Goodyear, Her special
licence that I, the said Charles Goodyear, my executors, administra-
tors, and assigns, or such others as I, the said Charles Goodyear,
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 therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdon of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF FABRICS," upon
the condition (amongst others) that I, the said Charles Goodyear, by
an instrument in writing under my hand and seal, 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 Goodyear, 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 waterproof fabrics made of fibres, and
cemented together by means of india-rubber cement. Heretofore in

page_text: making such fabrics it has been usual to employ india-rubber dissolved
in a suitable solvent, without other matters being mixed therewith.
Now the present Invention consists of mixing like fibres to those of
which the fabric is composed with the dissolved india-rubber, and then
to rise it in like manner to that in which the simple solution of india-
rubber has been used, by which means the fibres mixed with the
cement and the fibres of the fabric will interlack and combine, and
produce more advantageous results than when simple cement is used.
Having thus stated the nature of my said Invention, I will procced
to describe the manner of performing the same. In place of using
india-rubber cement in the ordinary state, I mix with it a quantity
of fibres such as the fabrics which are to be cemented together are
made of, or of other stronger fibres, and it is desirable that there
should be as much fibre mixed with the india-rubber cement as the
cement will take, and yet be sufficiently fluid to spread freely on
the surfaces of the fabrics which are to be cemented together, and it
will be found that this mode of cementing fabrics together is peculiarly
applicable to the cementing of fabrics made of fleeces of fibres combined
into a fabric by india-rubber cement. In other respects the ceinent
is to be used as heretofore, and the making of waterproof fabrics there-
with is to be performed as heretofore, and as is well understood.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
is, the combining fibres with india-rubber cement used in cementing
fabrics together when manufacturing waterproof fabrics.
In witness whereof, I, the said Charles Goodyear, have hereunto set
my hand and seal, this Twenty-second day of February, in the
year of our Lord One thousand eight hundred and fifty-four.
