for the Invention of "IMPROVEMENTS IN PREPARING THE SURFACES OF PAPER
OR OTHER MATERIAL FOR DRAWING PURPOSES, AND IN THE APPLICATION OF
THE SAME TO LITHOGRAPHIC AND OTHER. KINDS OF PRINTING."
Sealed the 28th February 1868, and dated the 9th October 1867.
PROVISIONAL SPECIFICATION left by the said Thomas Nelson at the
Office of the Commissioners of Patents, with, his Petition, on the
9th October 1867.
I, THOMAS NELSON, of Hope Park, Edinburgh, Publisher, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN. PREPARING
THE SURFACES OF PAPER OR OTHER MATERIAL FOR DRAWING PURPOSES, AND IN THE
APPLICATION OF THE SAME TO. LITHOGRAPHIC AND OTHER KINDS OF PRINTING," to be.
as follows:-
I employ a plate or cylinder of metal or other material or a sheet or film
of any substance or material with a minute granulated or lined pattern on
the surface for impressing the paper or other material. The paper or other
material so impressed is then ready for ordinary drawing purposes.
The following is the manner in which I usually operate-I take a sheet
of copper or other metal and I grain the surface, it may be. by the aquatint

page_text: process, or by the use of a graver by hand, or by a ruling machine, and I lay
a sheet of paper on the plate so prepared and pass it together with the plate
between calendering or hot pressing rollers; or in place of using a plate in
this manner the surface of one of the pressing rollers may be similarly
prepared. In the application of the same to the production of drawings,
writings, and designs for lithographic and other kinds of printing, I cover the
surface of the paper or other material with composition suitable for trans-
ferring drawings or designs to stone or metal, and then impress the paper with
the requisite pattern. The paper so prepared and impressed is then ready
for receiving the drawing or design. To produce surfaces in "relievo" and
"intaglio" for printing, stereotyping, or electrotyping, I print an impression
from the drawing or design which has been transferred to stone or metal ou
a surface of gelatine, gum, or other glutinous substance in combination with
the bichromates of potash, soda, or ammonia. The impression so printed is
then exposed to the light, and a plate is produced in the method described in
the Specification of Ramage and Nelson's Patent, dated the 21st day of
March 1866 (No. 887), or by other similar process.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Nelson in the Great Seal Patent Office on the 9th
April 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
NELSON, of Hope Park, Edinburgh, Publisher, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of October, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Nelson, Her special licence that I, the said Thomas Nelson,
my executors, administrators, and assigns, or such others as I, the said
Thomas Nelson, 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 "IMPROVE-
MENTS IN PREPARING THE SURFACES OF PAPER OR OTHER MATERIAL FOR DRAWING
PURPOSES, AND IN THE APPLICATION OF THE SAME TO LITHOGRAPHIC AND OTHER

page_text: KINDS OF PRINTING," upon the condition (amongst others) that I, the said
Thomas Nelson, 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 Thomas Nelson, do hereby declare the
nature of the 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 thereof, that is to say:-
I employ a plate or cylinder of metal or other material or a sheet or film
of any substance or material with a minute granulated or lined pattern on
the surface for impressing the paper or other material. The paper or other
material so impressed is then ready for ordinary drawing purposes.
The following is the manner in which I usually operate:-I take a sheet
of copper or other metal and I grain the surface, it may be by the aqua-
tint process, or by the use of a graver by hand, or by a ruling machine, and I
lay a sheet of paper on the plate so prepared and pass it together with the
plate between calendering or hot pressing rollers; or in place of using a plate
in this manner the surface of one of the pressing rollers may be similarly
prepared. In the application of the same to the production of drawings,
writings, and designs for lithographic and other kinds of printing, I cover the
surface of the paper or other material with compositions suitable for trans-
ferring drawings or designs to stone or metal, and then impress the paper
with the requisite pattern. The paper so prepared and impressed is then
ready for receiving the drawing or design which is to be done with any
suitable chalk or other ink for transferring. To produce surfaces in "relievo "
and "intaglio" from such drawings for printing, stereotyping, or electro-
typing, I print an impression from the drawing or design (which has been
transferred to stone or metal) on a surface of gelatine, gum, or other glutinous
substance in combination with the bichromates of potash, soda, or ammonia.
The impression so printed on the said bichromated material is then exposed
to the light and a printing plate is produced from it in the method described
in the Specification of Ramage and Nelson's Patent, dated the 21st day of
March 1866 (No. 887), or by other similar process..
What is specially claimed is the preparation and use of paper embossed
with a granulated lined, stippled, or otherwise finely marked surface for drawing
and sketching on, and also for lithographic drawing thereon, together with

page_text: the making of printing plates from impressions of the said lithographic drawings
as above described.
In witness whereof, I, the said Thomas Nelson, have hereunto set my
hand and seal, this Seventh day of April, in the year of our Lord One
thousand eight hundred and sixty-eight.
THOMAS NELSON. (L.B.)
