Year: 1853

page_text: LETTERS PATENT to Samuel Alfred Carpenter, of Birmingham, in
the County of Warwick, Manufacturer, for the Invention of "A
NEW OR IMPROVED ELASTIC WEBBING OR FABRIC."
Sealed the 14th November 1853, and dated the 23rd May 1853.
PROVISIONAL SPECIFICATION left by the said Samuel Alfred Car-
penter at the Office of the Commissioners of Patents, with, his
Petition, on the 23rd May 1853.
I, SAMUEL ALFRED CARPENTER, of Birmingham, in the County of
Warwick, Manufacturer, do hereby declare the nature of the said In-
vention for "A NEW OR IMPROVED ELASTIC WEBBING OR FABRIC" to be as
follows:-
My said Invention consists in introducing into elastic webbings and
fabrics a mixture of threads of ordinary caoutchouc and vulcanized
caoutchouc, the said threads being worked together in any desired
relative quantity and in any convenient manner. An elastic webbing
or fabric made according to my Invention is less costly than one made
with vulcanised caoutchouc alone, and the admixture of unvulcanised or
ordinary caoutchouc moderates or reduces the excessive elasticity of the
vulcanised caoutchouc, and produces a webbing or fabric sufficiently
elastic and more suitable for the purposes to which such webbings or

TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
SAMUEL ALFRED CARPENTER, of Birmingham, in the County of War-
wick, Manufacturer, send-greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of May, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said "Samuel Alfred Carpenter, Her special
licence that I, the said 'Samuel Alfred Carpenter, my executors, admi-
nistrators, and assigns, or such others as I, the said Samuel Alfred
Carpenter, 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 Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man,' an Invention for
"A NEW OR IMPROVED ELASTIC WEBBING OR FABRIC," upon the condition
(amongst others) that I the said Samuel, Alfred, Carpenter, 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

NOW KNOW YE, that I, the said Samuel Alfred Carpenter,
.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) :.
The object of my said Invention is the production of elastic webbings
or fabrics in which the degree of elasticity may be made to vary between
that of fabrics made of threads of vulcanized caoutchouc, and that of

page_text: fabrics made of threads of ordinary or unvulcanized caoutchouc. My said
Invention consists in introducing into elastic webbings and fabrics a
mixture of threads of ordinary caoutchouc and threads of vulcanized
caoutchouc, the said threads being worked together in any desired
relative quantities and in any convenient manner. I ordinarily use
alternate threads of vulcanized and unvulcanized caoutchouc, but I vary
the proportion as I require greater or less elasticity. I also modify the
elasticity by altering the weights used upon the warps of caoutchouc or
cotton in the process of weaving.
An elastic webbing or fabric made according to my Invention is less
costly than one made with vulcanized caoutchouc alone, and the mixture
of vulcanized with unvulcanized caoutchouc moderates or reduces the
excessive elasticity of the vulcanized caoutchouc, and produces a webbing
or fabric sufficiently elastic for all the purposes to which elastic
webbings or fabrics are usually applied.
I wish it to be understood that I herein use the expression vulcanized
caoutchouc to designate caoutchouc which has been rendered perma--
nently elastic by treatment with sulphur or otherwise, and that I use
the expression unvulcanized or ordinary caoutchouc to designate
caoutchouc which has not been rendered permanently elastic by treat--
ment with sulphur or otherwise.
I claim as my Invention making elastic webbing or fabric by intro-
ducing into the said fabric a mixture, in any proportion or in any way,
of threads of vulcanized and unvulcanized caoutchouc.
In witness whereof, I, the said Samuel Alfred Carpenter, have
hereunto set my hand and seal, this Twenty-first day of Novem-
ber, in the year of our Lord One thousand eight hundred and
fifty-three
SAMUEL ALFRED CARPENTER. (L.S.)
Witness, RICHARD SKERRETT.
