Pimlico, in the County of Middlesex, Gentleman, for the Invention
of "IMPROVEMENTS IN MAKING TARPAULING IN DIFFERENT COLOURS, AND IN
TREATING SAIL CLOTH AND OTHER FABRICS TO PRESERVE THEM FROX RAPID

Sealed the 6th April 1869, and dated the 29th January 1869.
PROVISIONAL SPECIFICATION left by the said Nicholas Charles
Szerelmey at the Office of the Commissioners of Patents, with his
Petition, on the 29th January 1869.
I, NICHOLAS CHARLES SZERELMEY, of Belgrave Road, Pimlico, in the
County of Middlesex, Gentleman, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MAKING TARPAULING IN DIFFERENT
COLOURS, AND IN TREATING SAIL CLOTH AND OTHER FABRICS TO PRESERVE THEE
FROM RAPID DESTRUCTION BY THE SEA AIR AND OTHER CORRODING INFLUENCES," to
be as follows:-
I boil in an iron pot one cwt. of gas tar until the same becomes hard,
and at the same time I boil in another iron steam jacketted pot

page_text: 14 gallons of Stockholm tar spirit, 10 lbs. of American rosin, and one
gallon of rosin oil. After the ingredients are completely dissolved I mix
the whole together, and in about 10 minutes time I mix therewith two
ounces of sulphuric acid; this is compound No. 1, and I use it for dark
tarpaulings and for preserving sail cloth and other fabrics.
I take 28 lbs. of red oxide of iron and grind it in a colour mill with
6 gallons of Stockholm tar spirit and 1 gallon of roşin oil in which 2 lbs.
of rosin powder are dissolved, after the whole is ground I mix in it
6 pints of No. 1 compound; this is compound No. 2, it is of a red colour
and I use it also for tarpaulings and sail cloth and other fabrics. Other
different colours can be prepared in a similar manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Nicholas Charles Szerelmey in the Great Seal
Patent Office on the 20th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NICHOLAS
CHARLES SZERELMEY, of 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 Twenty-ninth day of January, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Nicholas Charles Szerelmey, Her
special licence that I, the said Nicholas Charles Szerelmey, my exe-
cutors, administrators, and assigns, or such others as I, the said Nicholas
Charles Szerelmey, 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 MAKING TARPAULING IN DIFFERENT COLORS,
TREATING SAIL CLOTH AND OTHER FABRICS TO PRESERVE THEM FROM RAPID
DESTRUCTION BY THE SEA AIR AND OTHER CORRODING INFLUENCES," upon the con-
dition (amongst others) that I, the said Nicholas Charles Szerelmey, my
executors or administrators, by an instrument in writing under my, or

page_text: 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 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 has for its object improvements in making tarpaulings
in different colors and in treating sail cloth and other fabrics to preserve
them from rapid destruction by the sea air and other corroding influences.
I boil in an iron pot 1 cwt. of gas tar until the same becomes hard, and
at the same time I boil in another iron pot which is heated by steam
admitted between the pot and a jacket or casing which surrounds it
14 gallons of Stockholm tar spirit, 10 lbs. of American rosin, and one
gallon of rosin oil. When these ingredients are completely dissolved
and mixed they are drawn together with the boiled tar, which should be
at about the same temperature, into a mixing vat or vessel, and the
whole is thoroughly stirred together. When the mixing has been
continued for about ten minutes two ounces of commercial sulphuric
acid is added, and the mixing is continued. This is compound No. 1,
and it is suitable for the preparation of dark colored tarpaulings and
for preserving sail cloth and other fabrics. The cloth to be prepared
is spread on the ground, and composition which is heated sufficiently to
render it perfectly fluid is brushed into it with a hard brush, and so the
fabric is thoroughly saturated with the composition. When one side of
the fabric has been covered it is turned over and the other side is
similarly treated.
For tarpaulings I frequently apply more than one coating on each
side. To make a composition suitable for preparing red tarpaulings I
take 28 lbs. of red oxide of iron and grind it in a color mill with
6 gallons of Stockholm tar spirit, and 1 gallon of rosin oil in which
2 lbs. of rosin powder are dissolved, after the whole is ground I mix in
it 6 pints of No. 1 compound; this is compound No. 2. I use it in the
same manner as the composition No. 1 for tarpaulings, sail cloth, and
other fabrics. Other colors may be prepared in a similar manner by
substituting other pigments for the oxide of iron.

page_text: What I claim is the improvements in making tarpaulings and in
treating sail cloth and other fabrics, substantially as above described.
In witness whereof, I, the said Nicholas Charles Szerelmey, have
hereunto set my hand and seal, this Fourth day of May, in the
year of our Lord One thousand eight hundred and sixty-nine.
NICHOLAS CHARLES SZERELMEY. (L.S.)
