Year: 1875

page_text: LETTERS PATENT to Frederic Pelham Warren, of East Court, Cosham,
in the County of Hants, Captain in the Royal Navy, for the Inven-
PROVISIONAL SPECIFICATION left by the said Frederic Pelham
Warren at the Office of the Commissioners of Patents, with his
Petition, on the 20th April 1875.
I, FREDERIC PELHAM WARREN, of East Court, Cosham, in the County
3 of Hants, Captain in the Royal Navy, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND
SHOES," to be as follows:-
:―
My Invention has for its object to produce boots and shoes which
shall be impervious to moisture, very durable, and capable of having the
outer soles readily renewed. For this purpose I interpose intermediate
soles or layers of metal (preferring thin sheet copper) between the inner
soles and the outer soles of boots or shoes, and I provide strips or side
linings of leather coated with adhesive waterproof composition, as herein.

page_text: after described, such coated strips of leather having their upper parts
interposed between the lower parts of the uppers of the boots or shoes
and the inner linings, whilst the lower parts of the coated strips of
leather are held between the metal soles and the leather soles.
The composition I use for coating the strips of leather or side linings
consists of a mixture of bisulphate of carbon with raw gutta percha, the
latter being finely chopped and dissolved in the bisulphate of carbon.
The outer soles may be secured in place by screws passing through
them, through the leather strips, the metal soles or layers, the inner
linings, and some little distance into the inner soles; or the several parts
may be attached by sewing or otherwise.

times thereafter during the term therein expressed, should and lawfully

page_text: 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 Frederic Pelham Warren, 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) :—
My Invention has for its object to produce boots and shoes which
shall be impervious to moisture, very durable, and capable of having the
outer soles readily renewed. For this purpose I interpose intermediate
soles or layers of metal (preferring thin sheet copper) between the inner
soles and the outer soles of boots or shoes, and I provide strips or
side linings of leather coated with adhesive waterproof composition, as
heroin-after described, such coated strips of leather having their upper
parts interposed between the lower parts of the uppers of the boots or
shoes and the inner linings, whilst the lower parts of the coated strips of
leather aro held between the metal soles and the leather soles.
The composition I use for coating the strips of leather or side linings
consists of a mixture of bisulphate of carbon with raw gutta percha, tho
latter being finely chopped and dissolved in the bisulphato of carbon.
The outer soles may be secured in place by screws passing through
them, through the leather strips, the metal soles or layers, the inner
linings, and some little distance into the inner soles; or the several parts
may be attached by sewing or otherwise.
Having described the nature of my said Invention for improvements
in the manufacture of boots and shoes, and explained the manner of
carrying the same into practical effect, I hereby declare what I consider
to be novel and original and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent to be,-
First. The combination in boots and shoes of soles or layers of metal
with soles or layers of leather, as above set forth.
Secondly. The manufacture of boots and shoes in which soles or
layers of metal interposed between the inner and outer leather soles or
layers are used in conjunction with strips or side linings of leather

page_text: coated with adhesive waterproof composition, substantially in the manner
herein-before described.
In witness whereof, I, the said Frederic Pelham Warren, have
hereunto set my hand and seal, this Fifteenth day of October,
in the year of our Lord One thousand eight hundred and seventy-
five.
FREDERIC PELHAM WARREN. (L.s.)
