Sealed the 8th January 1853, and dated the 1st October 1852.
PROVISIONAL SPECIFICATION left by the said Moses Poole at
the office of the Commissioners of Patents, with his petition, on
the 1st October 1852.
I, MOSES POOLE, of Serle Street, in the County of Middlesex, Gen-
tleman, do hereby declare the nature of the said Invention for
IMPROVEMENTS IN COVERING AND SHEATHING SURFACES WITH A MATERIAL
NOT HITHERTO USED FOR SUCH PURPOSES" to be as follows:-
This Invention is a communication from America, on behalf of
Mr. Goodyear, the Inventor, and consists of employing sheets or surfaces
of a hard material, produced by combining India-rubber with sulphur,
with or without other materials, and subjecting the same to heat.

filed by the said Moses Poole, in the Great Seal Patent Office, on
the 30th March 1853
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
MOSES POOLE, of Serle Street, in the County of Middlesex, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First' day of October in the year of our
Lord One thousand eight hundred and fifty-two, in the sixteenth year
of Her reign, did for Herself, Her heirs and successors, give and grant
unto me, the said Moses Poole, Her special licence that I, the said
Moses Poole, my executors, administrators, and assigns, or such others
as I, the said Moses Poole, 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 law-
fully 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 COVERING AND SHEATHING SURFACES
WITH A MATERIAL NOT HITHERTO USED FOR SUCH PURPOSES," upon the
condition (amongst others) that I, the said Moses Poole, by an instru-
ment 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.

J
NOW KNOW YE, that I, the said Moses Poole,. 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 is a communication from America, on behalf of
Mr. Goodyear, the Inventor, and consists of employing sheets or surfaces
of hard material, produced by combining India-rubber with sulphur, with
or without other materials, and subjecting the same to heat. And in
order that the said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means, as practised by

page_text: the Inventor; and I would state at the outset, that this Invention has
for its object the producing sheets, either alone or combined with fabric
or fibre, suitable for sheathing or covering floors, roofs; vessels, and such
like uses.
}
When fabrics or fibres are used, the sheets of compound are spread
upon them in the usual way, and it is preferred for many uses to
double several of these coated fabrics together, for which purpose the
India-rubber, having been combined with sulphur by kneading or mas-
ticating them together, as is well understood, at the rate of two parts of
India-rubber by weight, to one part of sulphur (or in place of sulphur,
matters giving off like products of sulphur by heat may be used), and
in addition, gum lac, pitch, or coal tar deprived of water by heat, and
white lead, oxide of zinc, or other colouring matters may be mixed
therewith.
The same is to be rolled into sheets of the dimensions desired, and
where the sheets are not large enough for the purpose desired, different
breadths are cemented together in the usual way, before heating.
Where the article is smaller than the sheet, the size desired is cut
therefrom, and such compound may be connected to a fabric or fleece
which will bear the heat, particularly in cases where the sheathing or
covering is to he cemented to the surface it is intended to sheath.
And having produced such sheets, they are caused to be subjected to
heat, raising the temperature gradually, say to 230° of Fahrenheit in
about half an hour, retaining that heat for about one and a half hours,
and then increasing it gradually up to 295° to 305° of Fahrenheit in
the remainder of six hours, but where the compound contains a con-
siderable quantity of foreign matter, the heat may be raised more
quickly.
If very tough sheets are desired, then the heat is stopped from rising
up to 295°. These sheets, like sheets of metal, may be nailed, or fixed
by screws, and form an excellent covering to a roof, a ship's bottom, or
other surface, and such sheets may be reduced in thickness and extended
(when not combined with fabrics) by subjecting them to pressure
between hard and smooth rollers, the substance being at a temperature
about 300° Fahrenheit when rolled.

page_text: Having thus 'described the nature of this Invention, I would have it
understood, that what I claim is the manufacture of sheets for covering
and sheathing surfaces from a compound of India-rubber and sulphur,
with or without other matters, as herein described.
In witness whereof, I, the said Moses Poole, have hereunto set my
hand and seal, this Twenty-eighth day of March in the year
of our Lord One thousand eight hundred and fifty-three.
MOSES POOLE. (L.S.)
Witness, B. GOBEY.
