Sealed the 8th January 1858, 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 "IMPROVE-
MENTS IN THE MANUFACTURE OF TRUNKS, CARTOUCH AND OTHER BOXES,
KNAPSACKS, PISTOL-HOLSTERS, DRESSING, WRITING, AND OTHER CASES, AND
SWORD AND OTHER SHEATHS," to be as follows:-
This Invention is a communication from America, on behalf of
Mr. Goodyear, the Inventor, and consists of employing a material not

produced by combining India-rubber with sulphur, with or without
other materials, and subjecting the same to heat after it has been made
into the desired article.
SPECIFICATION in pursuance of the conditions of the Letters Patent
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
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
TRUNKS, CARTOUCH AND OTHER BOXES, KNAPSACKS, PISTOL-HOLSTERS,
DRESSING, WRITING, AND OTHER CASES, AND SWORD AND OTHER SHEATHS,"
upon the condition (amongst others) that I, the said Moses Poole, 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 Moses Poole, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: 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, in behalf of
Mr. Goodyear, the Inventor, and consists of employing a material not
hitherto used in such manufactures, and which is a hard substance
produced by combining India-rubber with sulphur, with or without
other materials, and subjecting the same to heat after it has been made
into the desired articles; and in order that the Invention may be most
fully understood, and readily carried into effect, I will proceed to describe
the means pursued by the Inventor. India-rubber and sulphur are to
be well mixed together by kneading or masticating, as is well understood,
with or without other materials, such as gum lac, gutta percha, pitch,
or coal tar deprived of water by heat, white lead, oxide of zinc, and
other colouring materials, such as have heretofore been used;. using at
the rate of two parts by weight of India-rubber and one part by weight
of sulphur; if other materials are also used, then a small additional
quantity of sulphur may be added.
The compound to be used being rolled into sheets, they are formed
into the articles above mentioned, by spreading the sheets upon forms
or in moulds, according to the shape and nature of the article, more
particularly where the article is to be wholly of the composition.. Wood
or sheet metal are considered best for forms, and solid metal is con-
sidered best for moulds.
.
In order to keep the covering in contact with the form, and to
facilitate the heating, the articles are placed in cases or frames and
surrounded with impalpable powder of talc or soap-stone, when the
sheets are exterior of the form or shape or mould; when the sheets are
in the interior of a mould or shape, sand is placed in the interior, and
heat is to be applied thereto gradually, say to 230° of Fahrenheit in the
first half hour, then to be retained at that degree for about one and a
half hours, then the temperature is to be raised gradually for the
remainder of six hours up to 295° to 305°. If the compound
contains a large proportion of foreign matter it is found that the heat
may be raised quicker. In making large and strong articles of the
descriptions above mentioned, and in any other articles, several layers

page_text: of such composition between woven fabrics, not injured by the heat, are
sometimes used in place of employing sheets of the composition. In
making boxes and cases, which require to be water and air tight where
they shut together, it is found desirable to form grooves and to inlay
therein vulcanized India-rubber where the parts come together, which
parts on being pressed or held in contact by any suitable fastenings will
render the cases or boxes water and air proof. For the purpose of
greater strength and. for economy of material in the manufacture of
most large articles, hoops or straps of metal may be applied upon the
inside or outside, around the top or other parts, in which cases such
hoops or straps are to be covered over with the substance and incorporated
therein, so as to form one with the article to which such hoops or straps
are applied. I would remark that this mode of moulding or shaping
articles of the hard substance above mentioned is not claimed generally
under the present Letters Patent, like means having been resorted to
for moulding and shaping articles, and described and claimed in the
specification of other Letters Patent granted to me on behalf of the
said Mr. Goodyear.
This Invention consisting of the application of the substance above
described in the manufacture of trunks, cartouch and other boxes,
knapsacks, pistol-holsters, dressing, writing, and other cases, and sword
and other sheaths.
In witness whereof, I, the said Moses Poole, have hereunto set
my hand and seal, this Twenty-eight day of March in the year
of our Lord One thousand eight hundred and fifty-three.
MOSES POOLE. (L.S.)
Witness, B. GOBEY.
