I WALTER BRIERLEY of Town Hall Buildings Halifax, in the County of York
Mechanical Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE PREPARATION AND MANUFACTURE OF PAPER SPECIALLY APPLICABLE
FOR LITHOGRAPHIC PURPOSES AND USES, TRACING AND TRANSFERRING," to be as
follows:
To the present time the lithographer uses a paper for transferring and reprinting
which is liable to stretching and warping in a manner which is very objectionable.
Such inconvenience is avoided by the improved paper hereinafter described and
which can be washed, will not expand; and is very fine transparent and pliant.
On this paper one can make with indian ink the finest strokes and lines, and
transfer to and print from the lithographic limestone, even when the drawing has been
made some days and is dry.
Also the newly invented paper can be washed in parts, where it is sometimes
necessary to make corrections, and yet it will not distort, on the contrary it retains its
original size whilst the other printing or transferring paper is expanded by moisture.
In the manufacture of the improved paper as aforesaid must be used a clean
lithographic limestone first rubbed over with linseed oil and rolled with a cylinder
pressing machine, on the said stone is to be laid a transparent paper such as generally
in use and covered with a thin plate of zinc or a pressing board and rolled through
the pressing machine.-The same operation is to be performed on the other side of the
paper and then it must be half dried for twenty four hours; then the same process
must be repeated once more.-Next the half dried paper is to be laid on a fine glass
plate and done over with a fine pencil brush, which is filled with two parts varnish
and one part clear turpentine, it must be done over on both sides, then once more it

should be washed with soap and water, cleansed with pure water and also dried and
now laid on a lithographic stone and rolled through the pressure machine. The
rolling through concludes the process.
The printing or drawing on paper so prepared can be washed or washed out and yet
will not shrink.
For reprinting or transferring from, this paper is used as follows:
From the original which may be a lithographic limestone a dry impression is to be
made on the paper, this impression is further made on another stone.-The latter which
must be clear and dry is touched with striated gypsum and etched with gum, then it
is rolled till the drawing is visible and it must be further etched. Now the drawing
shall be washed on the stone the latter touched with the required color and rolled,
when the desired impressions may be taken off. .

1, WALTER BRIERLEY of Town Hall Buildings, Halifax, in the County of York,
Mechanical Engineer do hereby declare the nature of this invention which invention
has been communicated to me from abroad by Joseph Leidl of Nurnberg, Germany
Painter, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
To the present time the lithographer uses a paper for transferring and reprinting
which is liable to stretching and warping in a manner which is very objectionable.
Such inconvenience is avoided by the improved paper hereinafter described, and
which can be washed, will not expand, and is very fine, transparent and pliant.
On this paper one can make with indian ink the finest strokes and lines, transfer to
and print on the lithographic limestone, even when the drawing has been made some
days and is dry.
Also the newly invented paper can be washed in parts, where it is sometimes
necessary to make corrections, and yet it will not distort, on the contrary it retains its
original size, whilst the other printing or transferring paper is expanded by moisture.
In the manufacture of the improved paper as aforesaid must be used a clean
lithographic limestone first rubbed over with linseed oil and rolled with a cylinder
pressing machine on the said stone is to be laid a transparent paper such as
generally in use and covered with a thin plate of zinc or a pressing board and rolled
through the pressing machine.
The same operation is to be performed on the other side of the paper and then it
must be half dried for twenty four hours; then the same process must be repeated
once more.
Next the half, dried paper is to be laid on a fine glass plate and done over with a
fine pencil brush, which is filled with two parts varnish, and one part clear turpentine ;
it must be done over on both sides, then once more it must dry for twenty four hours.
The dried paper is next laid on zinc plate and should be washed with soap and
water, cleansed with pure water and also dried and now laid on a lithographic stone
and rolled through the presser machine.
The rolling through concludes the process.
The printing or drawing on paper so prepared can be washed, or washed out, and
yet will not shrink.

page_text: For re-printing or transferring from this paper is used as follows
From the original which may be a lithographic limestone, a dry impression is to be
made on the paper, this impression is further made on another stone. The latter
which must be clear and dry is touched with striated gypsum and etched with gum,
then it is rolled until the drawing is visible, and it must be further etched.
Now the drawing shall be washed on the stone, the latter touched with the required
colour, and rolled when the desired impressions may be taken off.
Having now particularly described and ascertained the nature of the said Invention,
and in what manner the same is to be performed I declare that what I claim is;
The improved paper manufactured in the manner and for purposes and uses herein
set forth.
