IMPROVEMENTS IN THE MANUFACTURE OF PAPER CARTRIDGES, & IN PAPER APPLICABLE FOR WATERPROOF PURPOSES." PROVISIONAL SPECIFIC
Year: 1858

page_text: LETTERS PATENT to Charles Peterson, of Lowcliffe Lodge, Isle of Wight,
in the County of Hants, Gentleman, for the Invention of "IMPROVEMENTS
IN THE MANUFACTURE OF PAPER CARTRIDGES, & IN PAPER APPLICABLE FOR
WATERPROOF PURPOSES."
PROVISIONAL SPECIFICATION left by the said Charles Peterson at the
Office of the Commissioners of Patents, with his Petition, on the 24th
November 1858.
:
I, CHARLES PETERSON, of Lowcliffe Lodge, Isle of Wight, in the County of
Hants, Gentleman, do hereby declare the nature of the said Invention for
*IMPROVEMENTS IN THE MANUFACTURE OF PAPER CARTRIDGES, & IN PAPER'
APPLICABLE FOR WATERPROOF PURPOSES," to be as follows:-
My improvements relate, first, to the manufacture of cartridges, which may
either be made in their complete form at once from the pulp, as well under-
stood in making such articles, or the pulp may be first reduced to the form of
paper in sheets, and afterwards made into cartridges. According to my Inven-
tion, I introduce a solution of soap into paper pulp, and mix it intimately
therewith, after which I introduce alum in solution, which combines with and
decomposes the soap, and produces an insoluble substance, which extends

page_text: throughout the body of the paper or cartridges when made; and renders them
waterproof.
Papers for other purposes, in which they are required to be waterproof, I
manufacture in the same manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Peterson in the Great Seal Patent Office on the
24th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
PETERSON, of Lowcliffe Lodge, Isle of Wight, in the County of Hants, Gentle-
man, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of November, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Charles Peterson, Her special licence that I, the said Charles
Peterson, my executors, administrators, and assigns, or such others as I, the
said Charles Peterson, 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 makẹ,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF PAPER CARTRIDGES, AND IN PAPER APPLICABLE FOR
WATERPROOF PURPOSES," upon the condition (amongst others) that I, the said
Charles Peterson, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, 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 Peterson, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
-
My Invention relates to improvements in the manufacture of cartridge cases,:
and in paper applicable for waterproof: purposes; which manufacture of car

tridge cases may either be made in their complete form at once from the pulp,
as well understood in making such articles, or the pulp may be first reduced
to the form of paper in sheet, and afterwards made into cartridges.
.
According to my Invention, I introduce a solution of soap into paper pulp,
and mix it intimately therewith, after which I introduce alum in solution,
which combines with and decomposes the soap, and forms an insoluble sub-
stance, which extends throughout the body of the paper, or cartridge cases
when made, and renders them waterproof. Papers for other purposes, in
which they are required to be waterproof, I manufacture in the same manner.
In carrying out my Invention I take ordinary pulp, or such other pulps, as
may be adapted for the purposes of paper-making, & as reduced for paper-
making, and suitable for the purpose intended; with these pulps I mix about
two ounces of common soap for every gallon of pulp, first dissolving the soap
in a sufficient quantity of water to render it fluid. I mix this solution of
soap intimately with the pulp by stirring or otherwise, and until it is
thoroughly incorporated therewith; I then add to the mixture of pulp and
soap a solution of alum, adding this gradually, and stirring the pulp so as to
mix the alum thoroughly with the pulp. I watch the process closely until
I observe that the whole mass of pulp begins to curdle, adding the solution of
alum until the whole mass is curdled. The alum combines with the soap held
in solution in the pulp, and forms an insoluble matter which pervades the
body of the pulp, and consequently the paper or cartridges made therefrom.
I stir or otherwise, agitate the pulp continually for a period of half an hour
after the addition of the alum, which should cease when the curdling appears
complete.
The pulp so prepared requires no admixture of size, the alum and soap
answering all of the purposes of size in paper, besides having the property of
rendering the manufactured article waterproof.
The pulp prepared as before mentioned may either be used for making car-
tridge cases in the form of capsules as ordinarily practised, or it may be
manufactured into sheet paper by hand, or by ordinary paper-making machines
from which paper cartridge cases may be made, or such paper may be used
for other waterproof purposes.
Cartridge cases made according to my Invention, being waterproof, resist
humidity, and preserve powder enclosed in them in a perfect state for a
great length of time.
Having described the nature of my Invention and the manner of performing
the same, I declare that what I claim as my Invention to be protected by

page_text: the herein-before in part recited Letters Patent, is forming paper cartridge
cases, and paper for other. purposes waterproof, by combining soap and alum
therewith, for the purposes and as-herein-before described.
In witness whereof, I, the said Charles Peterson, have hereunto set my
hand and seal, this Nineteenth day of May, in the year of, our Lord
: "One thousand eight hundred and fifty-nine.
