Sealed the 2nd February 1866, and dated the 17th August 1865.
PROVISIONAL SPECIFICATION left by the said Nicholas Charles Szerelmey.
at the Office of the Commissioners of Patents, with his Petition, on the
17th August 1865.
I, NICHOLAS CHARLES SZERELMEY, of 90, Belgrave Road, Pimlico, in the
County of Middlesex, Gentleman, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF PAPER BOARDS AND
PIPES," to be as follows:-
This Invention has for its object improvements in the manufacture of paper
boards and pipes. To produce these articles I saturate paper with one or
other of the following preparations, according to the description of paper
which I employ.
One preparation consists of a solution of chloride of calcium and acetate of
lime. Of these salts I usually employ equal parts, but 'the proportion may
be varied.

page_text: Another preparation consists of silicate of potash and artificial sulphate of
baryta, and of these also equal parts may be employed.
A third preparation consists of anhydrous gypsum and caustic lye. The
mixture may be made by adding one part of gypsum to one part of alkali; in
each case, however, the proportions may be varied.
The paper having been saturated with one or other of these preparations is
I then saturate the paper a second time with a composition consisting
dried.
of,-
Gas tar
French siccatif
Zopissa
Pulp
Glue (dissolved)
One ton.
One ton.

Half a hundredweight.
-
One hundredweight.
One hundredweight.
The proportions of these materials will be varied to some extent according
to the nature of the paper and the process of preparation to which it has been 1
submitted. The substance I have called zopissa is a mineral found in Arabia
and America, and known in Arabia also by the name of "zorogh." The
pulp I employ is made from fibre, and is such as is used for making paper.
To produce paper boards the sheets of paper thus saturated are laid one on
the other and passed between rollers which subject them to a heavy pressure.
In this manner boards of any required substance are made.
To make pipes the saturated sheets of paper are rolled up on to a maundril,
and at the same time they are by suitable machinery subjected to a heavy
pressure; the paper is thus accumulated on the maundril until the required
substance is obtained. The maundril is made in parts to facilitate its 2
withdrawal:
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed.

Office on the 16th February 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NICHOLAS
CHARLES SZERELMEY, of 90, Belgrave Road, Pimlico, in the County of
Middlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of August, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto

page_text: me, the said Nicholas Charles Szerelmey, Iler special licence that I, the said
Nicholas Charles Szerelmey, my executors, administrators, and assigns, or
such others as I, the said Nicholas Charles Szerelmey, my executors, admi-
nistrators, 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 niight 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 PAPER BOARDS
AND PIPES," upon the condition (amongst others) that I, the said Nicholas
Charles Szerelmey, my executors or administrators, by an instrument in
writing under niy, 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 Nicholas Charles Szerelmey, do hereby
declare the nature of the said Invention, and in what mauner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
Heretofore in the manufacture of paper boards and paper pipes they have
been made by pasting or by otherwise cementing several layers or thicknesses
of paper together, and in some cases the paper so used has been saturated or
combined with tar. Now according to my Invention the paper employed is
first prepared by being saturated by one or other of the three compounds
hereafter mentioned, and the sheets or pieces of paper are then combined or,.
reinented together in any number of layers, according to the purpose to which
the boards or pipes are to be applied, by means of a cementing compound
composed of the following substances or matters mixed together in about the
following proportions, viz.
One ton of coal tar

page_text: ery sort an
salts:.'
porous Suture
the following
One part by weight of chloride of calcium..
One part by weight of acetate of lime.
Twenty parts of water.
If the paper is less soft and less porous I saturate it with a solution
composed as follows:-Silicate of potash and artificial sulphate of baryta in
equal parts in about sixteen parts of water.
These two solutions may be applied in succession to the same., paper, in
those cases where the paper after being saturated with the first solution is
found after being dried still capable of absorbing water."
Other papers are saturated with the following compound :-Anhydrous
gypsum and caustic potash in equal parts or proportions in about ten parts of
water. The paper having been well saturated in either of these compounds
or solutions is, when dry, suitable for carrying out my Invention, and any
number of sheets or layers may be cemented or combined together by the
compound above described, which is spread over the surfaces of the prepared
paper in like manner to that in which paste or other cements have been used
in producing paper boards and paper pipes.
In the above description I have been precise in giving the proportions of
the materials as used by me. I do not, however, confine myself to the precise
quantities or proportions; what I claim is, the manufacture of paper boards
and paper pipes by combining suitable paper in layers by means of á com-
position or cement, consisting of tar, French siccatif, zopissa, and glue,
substantially as herein described.

In witness whereof, I, the said Nicholas Charles Szerelmey,, have here-
'unto set my hand and seal, this Ninth day of February, in the year
of our Lord One thousand eight hundred and sixty-six.
