Year: 1858

page_text: LETTERS PATENT to Alois Winkler, of Vienna, in the Austrian Empire,
but now residing in Leicester Square, in the County of Middlesex,
Manufacturer, for the Invention of "IMPROVEMENTS IN PRINTING OR PRO-
DUCING IMPRESSIONS IN GOLD, SILVER, AND OIL COLORS UPON METALLIC PLATES,
AND IN THE MECHANISM EMPLOYED THEREIN."
Sealed the 26th October 1858, and dated the 28th April 1858.
PROVISIONAL SPECIFICATION left by the said Alois Winkler at the
Office of the Commissioners of Patents, with his Petition, on the 28th
April 1858.
I, ALOIS WINKLER, of Vienna, in the Austrian Empire, but now residing
in Leicester Square, in the County of Middlesex, Manufacturer, for "IMPROVE-
MENTS IN PRINTING OR PRODUCING IMPRESSIONS IN GOLD, SILVER, AND OIL COLORS
UPON METALLIC PLATES, AND IN THE MECHANISM EMPLOYED THEREIN," to be as
follows:-
I take a lithographic stone duly prepared, and make inscription or delinea-
tion with pen or pencil; from this I print off a copy or copies on a fine lined
paper covered with a paste, consisting two parts of gum and one part of meal;
the paper is to be dried a few hours, and cut to the size of the printing plates.
The color or ink used to print with is to be amalgamated with a strong oil
varnish upon the grinding stone, and nicely ground or rubbed, and the color is
to be laid on with the common printing roller or cylinder When printing

page_text: with gold or silver (gold oil colors), the paper remains without the paste, and
the printing is effected as above stated. After taking away the paper, the
printing is to be laid on with gold or silver.
To print on the metallic plate I use a press which has a suitable frame, with
a moveable bed plate for carrying the printing plate, &c., this moves longi-
tudinally within the said framing upon rails or slides, and has a counterbalance
weight at the end. Upon this bed plate there is a flat piece of wood with
edge plates for holding the printing plate, &c., to be printed; at the other end
of the bed plate, opposite to. the counterbalance weight, is a roller, and on to
this the bed plate, &c. is pushed (the roller being immediately beneath it),
and then the roller is worked by suitable handles & gearing connected there-
with, whereby the bed, &c., with the printing plate, &c., is brought under a
pressing bar which is brought down by lever & screw power, and the bed
plate, &c., is kept rolling under the presser until completely drawn through,
when the presser is to be relieved & then the bed plate, &c., is drawn back by
the counterbalance weight to its original position. The metallic plate in a dry
state is taken, scraped with a prepared rush stone, and then it is laid upon the
above mentioned flat piece of wood. Take the print out from the wetted
'paper and place it on the fastened plate, which must be provided with some
sheets of paper.
The above is a description of the nature of the Invention, which might pro
bably be varied in practice as regards its detail.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alois Winkler in the Great Seal Patent Office, on the 27th
October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALOIS
WINKLER, of Vienna, in the Austrian Empire, but now residing at Leicester
Square, in the County of Middlesex, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Alois Winkler, Her special licence that I, the said Alois Winkler, my
executors, administrators, and assigns, or such others as I, the said Alois
Winkler, 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

page_text: 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 PRINTING OR
PRODUCING IMPRESSIONS IN GOLD, SILVER, AND OIL COLORS UPON METALLIC PLATES,
AND THE MECHANISM EMPLOYED THEREIN," upon the condition (amongst others)
that I, the said Alois Winkler, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE that I, the said Alois Winkler, 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:-
I take a lithographic stone, duly prepared, and make inscription or delinea-
tion with pen or pencil; from this I print off a copy or copies, by means of
the press or mechanism commonly employed by lithographers.
First, the color or ink used to print with is to be amalgamated with a
strong oil varnish upon the grinding stone, and nicely ground or rubbed,
and the colors to be laid on in the manner and by the means usually adopted
by lithographic printers. After this the stone must be wiped over from all
sides, and this done, the writing must be cleaned with or by means of a wet
sponge. Then take a paper which is not "sized," and cover it with a paste
consisting of one part of gum and two parts of starch flour; the paper is then
to be dried a few hours, and cut to the size of the metallic plates to be printed,
and afterwards to be put upon the written or lithographed stone, and passed
through the common press; this done, the printing follows. The printed paper
is to be laid between two sheets of wet paper. Proceed now to the printing
of the plate, for which is required the plate printing press exhibited by the
annexed Drawing.
When printing with gold or silver (gold oil colors), the paper, which is
common "sized" paper, remains without the paste, and the printing is effected
as above stated, but it must afterwards be lightly wiped with a piece of cotton.
After taking away the paper the printing is to be laid with gold or silver, and
afterwards varnished.
To print on the metallic plate, I use a press (see Drawing annexed hereto),
which has a suitable framing A, A, A*, A*, with moveable bed plate B, of
wood or other suitable material carrying the plate to be printed; this moves

page_text: longitudinally within the frames (or slides upon rails), and has a counter
balance weight c at the end; upon this bed plate there is a flat piece of wood
with edge plates for holding the plate to be printed. The "scraper "
The "scraper" or pressing
bar E is moveable by means of a wheel G acting on a screw. On to the
roller D, the bed plate, having the plate to be printed properly placed thereon
is to be pushed, being thus brought underneath the said "scraper" or pressing
bar (E), which is then to be brought down upon the same by turning the wheel
G, and is to be further pressed thereon by moving the lever F, which effects
the required pressure; finally, the wheel (H) upon its motion, effects the pas
sage of the plate, which may be assisted by the crank handle h, and the printing
being thus effected, the pressure is to be relieved, and, by means of the counter-
balance weight, the plate is drawn back into its former position.
The metallic plate, varnished and in a dry state, is taken and scraped with a
prepared rubbing stone, and then is laid upon the above-mentioned flat pieces
of wood; when take the print out from the wetted paper, and place it on the
plate to be printed on, which must be provided with some sheets of paper,
upon which comes a strong cover of leather, when the printing may be
effected as described. The plate with the printed paper thereon is then to be
taken from the press, wiped with a wet sponge, and after five minutes the
paper is to be taken away and the operations completed.
Having now described the nature of the said Invention, and in what manner
the same is to be performed, I declare that I claim the Invention as herein-
before set forth and described; but I do not claim the details thereof, con-
sidered separately and apart from the purposes of my said Invention.
In witness whereof, I, the said Alois Winkler, have hereunto set my
hand and seal, this Eighteenth day of October, in the year of our Lord
One thousand eight hundred and fifty-eight.
ALOIS WINKLER. (L.S.)
