AN IMPROVED PRINTING PRESS
Year: 1875

page_text: LETTERS PATENT to Albert Ellis Redstone, of the City of Oakland,
in the County of Alameda, State of California, and United States
of America, for the Invention of “AN IMPROVED PRINTING PRESS.”
PROVISIONAL SPECIFICATION left by the said Albert Ellis Redstone
at the Office of the Commissioners of Patents, with his Petition,
on the 16th November 1875.
I, ALBERT ELLIS REDSTONE, of the City of Oakland, in the County of
Alameda, State of California, and United States of America, do hereby
declare the nature of the said Invention for "AN IMPROVED PRINTING
PRESS," to be as follows:-
-
My Invention relates to a printing press which has an endless belt,
carrying forms having card separators attached to the chase in combi-
nation with a card hopper or other suitable device.
The frame of my printing press may be made in any suitable manner.
The endless belt is supported upon and moved by rolls, one of which is

page_text: This
provided with a hand crank, or it may be moved by power if desired.
Press beds are attached to and move with the endless apron or toggle
belt. They are held in place by means of ears which rock on a pivot in
passing around the rolls. These press beds slide upon ways while
printing. The printing is done by an impression roll which has adjustable
bearings to regulate the amount of pressure in the usual manner.
roll is provided with a cylinder tympan of vulcanized india-rubber or
other suitable material. The interior diameter of this tympan is con-
siderably greater than the diameter of the roll, so that the tympan
forms a loose sleeve, the rotation of which is regulated by the speed of
the endless belt that carries the press beds and type. By this arrange-
ment the impression roll is relieved from all tendency to slide upon the
type, and the roll thus gives only the downward pressure and leaves a
clear impression in printing.
The cards or sheets of paper are placed in the feed hopper and the
press beds are provided with fingers or card separators, which in passing
under the hopper seize the lowest of the cards or sheets of paper and
carry the same forward on the form under the roll to be printed, and
finally drop the card or sheet while passing down over the roll. By
careful adjustment these card separators will separate very thin sheets 2
of paper.
A collar on the end of the ink rolls raises the rolls by means
of projections at the sides of the forms opposite the card separators.
The forms are inked in the usual way.
The number of the press beds may be increased at pleasure to print
any number of impressions at each complete revolution of the belt. The 2
better way is to make a number of stereotype plates and attach them to
the belt. By this method the amount of work done by the press may
be multiplied indefinitely, especially in printing cards or circulars.
The card takers are raised by means of a spring, and are adjusted to
the proper height by means of screws which by being drawn back allow 3
the same to rise, and by being set in prevent the rising of the same too
high.

Patent, and of an Order of the Lord Chancellor, by the said Albert
Ellis Redstone in the Great Seal Patent Office on the 30th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALBERT
ELLIS REDSTONE, of the City of Oakland, in the County of Alameda,
State of California, and United States of America, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Albert Ellis Redstone, Her
special licence that I, the said Albert Ellis Redstone, my executors,
administrators, and assigns, or such others as I, the said Albert Ellis
Redstone, 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 "AN IMPROVED PRINTING PRESS," upon the condition
(amongst others) that I, the said Albert Ellis Redstone, 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 on or before the Thirty-first day of May, One thousand
eight hundred and seventy-six.
NOW KNOW YE, that I, the said Albert Ellis Redstone, do hereby
declare the nature of my 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 accompanying
Drawing forming a part of this Specification :-
My Invention relates to a printing press which has an endless belt
carrying forms having card separators attached to the chase, in combi-
nation with a card hopper or other suitable device, as herein-after fully
described by the aid of the accompanying Drawing, in which,-
Figure 1 is a side elevation of the said printing press; Figure 2 is a
vertical longitudinal section of the same.

page_text: Figure 3 is a side view of a card separator shewing its attachment to
the chace of the said press; and Figure 4 is a front view of the said
card separator or taker, also showing its attachment to the chase. These
two Figures are drawn to an enlarged scale.
The frame of my printing press may be made as shown at A, Figure 1,
or in any other suitable manner; the endless belt B is supported upon
and moved by the rolls C, one of which is provided with a hand crank D,
or it may be moved by steam or other power if desired; press beds
or forms E attached to and move with the endless apron or toggle
belt B; they are held in place by means of ears F which rock on a
pivot in passing around the rolls C; these press beds slide upon the
ways H while printing as follows:-The printing is done by an im-
pression roll K. which has adjustable bearings to regulate the pressure in
the usual manner. This roll is provided with a cylinder tympan P of
vulcanized india-rubber or other suitable material. The interior diameter
of this tympan is considerably greater than the diameter of the roll, so
that the tympan forms a loose sleeve, the rotation of which is regulated
by the speed of the endless belt B that carries the press beds and type.
By this arrangement the impression roll K is relieved from all tendency
to slide upon the type, and the roll thus gives only the downward
pressure and leaves a clear impression in printing.
The cards or sheets of paper are placed in the feed hopper I, and the
press beds E are provided with fingers or card separators O which in
passing under the hopper seize the lowest of the cards or sheets of paper
and carry the same forward on the form under the roll K to be printed,
and finally drop the card or sheet while passing down over the roll C.
By careful adjustment these card separators O will separate very thin
sheets of paper.
A collar on the end of the ink rolls R, Figure 1, raises
the rolls by means of projections at the sides of the forms E opposite
the card separators. The forms are inked in the usual manner, as shown
at R, Figure 1.
The number of the press beds may be increased at pleasure to print
any number of impressions at each complete revolution of the belt. The
better way is to make a number of steareotype plates and attach them to
the belt. By this method the amount of work done by the press may
be multiplied indefinitely, especially in printing cards or circulars.
The card takers O are raised by means of the onzine a Tiaus 2

page_text: and 4, and are adjusted to the proper height by means of the screws T,
which by being drawn back allows them to rise, and by being set in
prevent the rising of the same too high.
Having thus fully described my said Invention, and the manner of
performing the same, I wish it understood that I claim,—
First. The endless apron or belt B having forms E attached thereto
in combination with the ink rolls R, the impression roll or cylinder K,
and the card trough or hopper I, in the manner and for the purposes
above set forth.
Second. The automatic feed or card separators when operated in the
manner and for the purposes above set forth.
In witness whereof, I, the said Albert Ellis Redstone, have here-
unto set my hand and seal, this 4th day of April, A.D.
1876.
ALBERT ELLIS REDSTONE. (L.S.)
