Year: 1873

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVEMENTS IN PRINTING
PRESSES." A communication from abroad by Samuel Hogg Bingham,
of Philadelphia, in the State or Pennsylvania, Edward Beattie Bing-
ham, of Newark, in the State of New Jersey, George Washington
Van Allen, of the City and State of New York, and William Nelson
Stone, of Philadelphia, aforesaid, all in the United States of
America.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 18th February 1873.

page_text: declare the nature of the said Invention for "IMPROVEMENTS IN PRINTING
PRESSES," to be as follows:-
The object of this Invention is to so construct a printing press that the
exactly opposite sides of a sheet or the outer sides of two sheets can be
printed simultaneously, or a sheet printed on opposite sides at intervals;
and the Invention principally consists in the connection with each other
of two printing cylinders, placed parallel and close to each other so that
the paper to be printed will pass between them, both said cylinders being
printing cylinders, and both also pressure cylinders, cach one printing
and each one pressing.
The Invention applies to all cylinder presses not furnished with raised
printing surfaces, that is, to those whose cylinders are either lithographic
stones or covered with prepared zinc or other metallic etched or prepared
impression plates. Suitable inking rollers are used in connection with
the cylinders for the purpose of applying ink to their surfaces, and also
suitable damping or wiping rollers, such rollers being set on opposite
sides of the printing cylinders.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 16th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Alfred
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of February, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her special
licence that I, the said Alfred Vincent Newton, my executors, admi-
nistrators, and assigns, or such others as I, the said Alfred Vincent
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great

page_text: Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN PRINTING PRESSES," being a communication to
me from abroad by Samuel Hogg Bingham, of Philadelphia, in the State
of Pennsylvania, Edward Beattie Bingham, of Newark, in the State of
New Jersey, George Washington Van Allen, of the City and State of
New York, and William Nelson Stone, of Philadelphia, aforesaid, all in
the United States of America, upon the condition (amongst others) that
I, the said Alfred Vincent Newton, 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 Alfred Vincent Newton, 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, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that is
to say) :-
The object of this Invention is so to construct a printing press as to
enable it to print exactly opposite sides of a sheet or the outer sides of
two sheets simultaneously; or to print a sheet on opposite sides at
intervals; and the Invention principally consists in the connection with
cach other of two printing cylinders placed parallel and close to each
other, so that the paper to be printed will pass between them, both said
cylinders being printing cylinders and both also pressure cylinders, each
one printing and each one pressing.
The Invention is applicable to all such presses not containing type
whose cylinders are either lithographic stones or covered with prepared
zinc or other metallic etched or prepared impression plates.
In the accompanying Drawing which represents in transverse section
so much of a printing press as will serve to explain the nature of the
Invention, A is the upper printing cylinder, and B the lower printing
cylinder. They are mounted parallel to each other in a frame C of
suitable construction and are both or either one of them adjustable in
their bearings to enable them to be brought sufficiently close together to

page_text: apply the requisite degree of pressure to the sheet passing between them.
These rollers are represented as covered with printing plates a, a, but
they may be made of stone or other material not containing type.
Suitable inking rollers are used in connection with these cylinders for
the purpose of applying ink to their surfaces, and also suitable damping t
or wiping rollers d.
A sheet passing between the two rollers A, B, will it is evident be
printed on both sides, and the two cylinders may be prepared to produce
different impressions on the opposite sides of the sheet, or also the same
impression as may be desired. And whenever it is not desired to print 1
two sides of one sheet two sheets may be simultaneously passed between
the two rollers A, B, in which case the upper cylinder will print the
upper face of the upper sheet, and the lower cylinder the lower face of
the lower sheet.
The printing surfaces of the two cylinders may be so prepared that 1
they do not always print exactly opposite parts of one or two sheets, and
in that case one cylinder will print while the other presses, and vice
versa, while otherwise both will print and press at one and the same
time.
Having not set forth the nature of the Invention of "Improve-
ments in Printing Presses," as communicated to me by my foreign cor-
respondents, and explained the manner of carrying the same into effect,
I wish it to be understood that under the above in part recited Letters
Patent I claim, the application to printing machinery of two printing
cylinders so arranged in connection with inking and wiping or
damping rollers, that cach cylinder will act as a pressure cylinder on the
other during the printing process, in the manner and for the purpose
above described.
In witness whereof, I, the said Alfred Vincent Newton, have here-
unto set my hand and seal, the Sixteenth day of August, in the
year of our Lord One thousand eight hundred and seventy-
three.
