Year: 1873

page_text: LETTERS PATENT to Benjamin George George, of 47, Hatton Garden,
Holborn, in the County of Middlesex, Lithographer, for the Inven-
tion of "IMPROVEMENTS IN THE METHOD OF TRANSFERRING PRINTED MATTER
TO PLATES OF METAL.".
Sealed the 9th April 1874, and dated the 27th October. 1873.
PROVISIONAL SPECIFICATION left by the said Benjamin George
George at the Office of the Commissioners of Patents, with his
Petition, on the 27th October 1873.
I, BENJAMIN GEORGE GEORGE, of 47, Hatton Garden, Holborn, in
5 the County of Middlesex, Lithographer, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE METHOD OF TRANSFERRING
PRINTED MATTER TO PLATES OF METAL," to be as follows:
This Invention is for improvements in the method of transferring
printed matter to plates of metal, and consists in a modification of the
0 process of transferring the printed work to plates of metal hitherto
performed in the following manner :-The printed paper with the design
or matter to be transferred is placed face down upon the painted sheet of
metal, or which may be either plain or varnished, the surface being
previously prepared with some tacky substance, and then subjected to the
.

page_text: action of a lithographic press; generally once passing through is not
sufficient; several passes under the press are required to effect a proper
transfer, and it is scarcely possible to make more than one transfer at a
time.
Now by my improved processes I abandon the use of the lithographic
press, and cause the transfer of the design to the plate of metal to be
made by roller pressure, that is to say, I take one or more sheets of
metal (either painted in the ordinary manner or plain, and prepared in
accordance with my Invention, for which I obtained Letters Patent in
England in the year 1870, and numbered 600) with the printed design
placed face down thereon, and I prefer, though it is not necessary, to put
each metal so prepared between sheets of cardboard, and I then subject
the whole to the action of a pair of powerful revolving rollers, the
pressure of which I so regulate that one pass is sufficient to cause the
transfer of ten, twenty, or even forty designs to as many sheets of metal,
and the number of such transfers which may be made at one time by
this process is only limited by the power of the rollers used.
.
The saving of labour and time in this my Invention is very great
when applied to transferring to ordinary painted sheets, of metal, and it
is especially applicable and necessary to the perfecting and following
out economically the processes as described in the above mentioned
Letters Patent.
I have not described the actual method of preparing the design on the
transfer paper or the preparation of the plates of metal, nor have I
described the subsequent operation of removing the transfer paper by
wetting the back thereof, all of which are commonly known in the trade,
and as to my own method are particularly set forth in the before men-
mentioned Letters Patent, No. 600, of 1870.
My Invention relates cntirely to the substitution of roller pressure in
place of the scraping action now in use by means of the lithographic
press.
Although I have only described the use of one pair of rolls; the roller
pressure may be applied also by means of one roller acting on a flat bed
plate, the bed plate itself running on a roller or rollers or wheels, and
so sliding under the one roll to receive the pressure as described.

filed by the said Benjamin George George in the Great Seal Patent
Office on the 27th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
GEORGE GEORGE, of 47, Hatton Garden, Holborn, in the County of
Middlesex, Lithographer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of October, in the.
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Benjamin George George Her
special licence that I, the said Benjamin George George, my executors,
administrators, and assigns, or such others as I, the said Benjamin George
George, 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 THE METHOD OF TRANSFERRING PRINTED MATTER TO
PLATES OF METAL," upon the condition' (amongst others) that I, the
said Benjamin George George, my executors or administrators, by
an instrument in writing under my, or their, or one of hands hands
and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be per-
formed, 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 Benjamin George George, 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 is for improvements in the method of transferring
printed matter to plates of metal, and consists in a modification of the
process of transferring the printed work to plates of metal hitherto
performed in the following manner;-The printed paper with the design:
i

page_text: or matter to be transferred is placed face down upon the painted sheet of
metal, or which may be either plain or varnished, the surface being
previously prepared with some tacky substance, and then subjected to the
action of a lithographic press; generally once passing through is not
sufficient; several passes under the press are often required to effect a
proper transfer, and it is scarcely possible to make more than one
transfer at a time.
Now by my improved processes I abandon the use of the litho press,
and cause the transfer of the design to the plate of metal to be made by
roller pressure, that is to say, I take one or more sheets of metal (either :
painted in the ordinary manner or plain, and prepared in accordance
with my Invention, for which I obtained Letters Patent in England in
the year 1870, and numbered 600) with the printed design placed face-
down thereon, and I prefer, though it is not necessary, to put each metal
so prepared between sheets of cardboard, and I then subject the whole
to the action of a pair of powerful revolving rollers, the pressure of
which I so regulate that one pass is sufficient to cause the transfer of
ten, twenty, or even forty designs to as many sheets of metal, and the
number of such transfers which may be made at one time by this
process is only limited by the power of the rollers used.
The saving of labor and time in this my Invention is very great
when applied to transferring to ordinary painted sheets of metal, and it
is especially applicable and necessary to the perfecting and following out
economically the processes described in the above-mentioned Letters
Patent.
I have not described the actual method of preparing the design on the
transfer paper or the preparation of the plates of metal, nor have I
described the subsequent operation of removing the transfer paper by
wetting the back thereof, all of which are commonly known in the
trade.
My Invention relates entirely to the substitution of roller pressure in
place of the scraping action now in use by means of the lithographic
press.
Although I have only described the use of one pair of rolls, the roller
pressure may be applied also by means of one roller acting on a flat bed
plate, the bed plate itself running on a roller, rollers, or wheels, and so
sliding under the one roll to receive the pressure as described.

page_text: I have not described any particular machinery, as there are very many
presses used in the trades connected with printing and paper work that
would be suitable, but I mention two especially adapted, the copper
plate printers' press and the double roller press used by paper makers for
giving a polished surface to paper, both of which are too well known to
need description.
Having now described and particularly set forth my Invention and the
best means I am acquainted with for putting the same into practice, I
would have it understood that what I claim and desire to be secured by
the herein in part recited Letters Patent is, the method of transferring
printed matter to plates of metal by the use of roller pressure, sub-
stantially as described.
In witness whereof, I, the said Benjamin George George have here-
unto set my hands and seal, this Twenty-seventh day of April, in
the year
of our Lord One thousand eight hundred and seventy-
four.
