Flat Type or Stereotype both Sides of the Paper Supplied
from a Continuous Web or Roll.
We, GEORGE TOULMIN, of 127 Fishergate, Preston, in the County of Lancaster,
Newspaper Proprietor, and WALTER BOND, of 10 Christian Road, in the same
place, Newspaper Overseer, do hereby declare the nature of said invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING FROM FLAT type
OR STEREOTYPE BOTH SIDES OF THE PAPER SUPPLIED FROM A CONTINUOUS WEB
OR ROLL," to be as follows :—
According to this invention we employ two flat type or stereotype tables suitably
mounted to slide horizontally, a reciprocating backward and forward movement
being imparted to the type tablos by means of rack and pinion or other convenient
mechanism for imparting a reciprocatory motion. Each of the type tables has
arranged above it its own set or series of impression cylinders, the first type table
and its impression cylinders being arranged to print one side of the
paper which
when printed is carried forward over suitably placed carriers or rollers to the second
type table and impression cylinders where it is "backed" or receives an impression
on its other or unprinted side. Suitable appliances are caused to ink the type of
each table in the ordinary manner. On the return or backward movement of the
type tables the impression cylinders are caused to be raised clear of the type until
the type table has passed under and beyond the impression cylinders when the
latter are depressed or lowered so as to be in position for printing when the table
is again moved forward and passed underneath them. The web or roll of paper to
be printed is placed in the centre of the machine above the sliding type tables and
between the two sets of impression cylinders.
The paper is first taken underneath the first of the set or series of impression
cylinders in connexion with the first type table and then upwards over a carrier or
registering roller above and down again under the second impression cylinder then
over a second carrier above and so on throughout the series of impression cylinders.
It is then taken upwards and over the roll or web upon suitable carriers and
then downwards to the second set or series of impression cylinders through which
037

page_text: and over the registering rollers above it is conducted in the same manner as
through the first set or series. By the above described arrangement the paper after
receiving an impression on one side from the first set of impression cylinders is
caused to present its unprinted side to the second set of impression cylinders by
which it is "backed" or receives an impression on its unprinted side whereupon it
may be carried forward to cutting cylinders and delivered flat on a receiving table
or, if desirable, to folding apparatus of the usual or any convenient kind.
The registering rollers and carriers are provided with regulating appliances so
that the register and unprinted spaces or intervals between the printed matter may
be readily adjusted.

We, GEORGE TOULMIN, of 127 Fishergate, Preston, in the County of Lancaster,
Newspaper Proprietor, and WALTER BOND, of 10 Christian Road, in the same
place, Newspaper Overseer, do hereby declare the nature of our invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING FROM FLAT TYPE
OR STEREOTYPE BOTH SIDES OF THE PAPER SUPPLIED FROM A CONTINUOUS WEB
OR ROLL "and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
According to this invention we employ two flat type or stereotype tables suitably
mounted to slide horizontally, a reciprocating backward and forward movement
being imparted to the type tables by means of a rack and pinion or other convenient
mechanism for imparting a reciprocating motion. Each of the type tables has
arranged above it its own set or series of impression cylinders, the first type table
and its impression cylinders being arranged to print one side of the paper which
when printed is carried forward over suitably placed carriers or rollers to the second
type table and impression cylinders where it is "backed or receives an impression
on its other or unprinted side. Suitable appliances are caused to ink the type of
each table in the ordinary manner, On the return or backward movement of the
type tables the impression cylinders are caused to be raised clear of the type until
the type table has passed under and beyond the impression cylinders when the
latter are depressed or lowered so as to be in position for printing when the table
is again moved forward and passed underneath them. The web or roll of paper to
be printed is placed in the centre of the machine above the sliding type tables and
between the two sets of impression cylinders.
The paper is first taken underneath the first of the set or series of impression
cylinders in connexion with the first type table and then upwards over a carrier or
registering roller above and down again under the second impression cylinder then
over a second carrier above and so on throughout the series of impression cylinders.
It is then taken upwards and over the roll or web upon suitable carriers and then
downwards to the second set or series of impression cylinders through which and
over the registering rollers above it is conducted in the same manner as through the
first set or series. By the above described arrangement the paper after receiving
an impression on one side by the first set of impression cylinders is caused to
present its unprinted side under the second set of impression cylinders by which it
is backed" or receives an impression on its unprinted side whereupon it may be
carried forward to cutting cylinders and delivered flat on a receiving table, or, if
desirable, to folding apparatus of the usual or any convenient kind.
The registering rollers and carriers are provided with regulating appliances so
that the register and unprinted spaces or intervals between the printed matter may
be readily adjusted.
In the accompanying drawing a a³ are the two flat or stereotype tables connected
together and moved backwards and forwards by a continuous toothed rack and

page_text: pinion apparatus b of the usual well known character. The first type table a
serves the first set of impression cylinders cccc and the second type table a¹ the
second set of impression cylinders c¹ c² c¹ c. d, e, f, and g represent ordinary ink
feeding and distributing rollers and h h inking rollers arranged and operating in
the ordinary manner. j is the web or roll from which the paper is conducted over
the carrier roller k down to the first impression cylinder and then under the
impression cylinders cccc and over the registering rollers ll as shewn. The
paper is then conducted over the carrier rollers m n to the second set of impression
cylinders and passed under and over the cylinders c¹ c¹ c² c¹ and rollers
alternately in the same manner as through the first series of impression cylinders.
It is then conducted over the carrier roller o to the cutting cylinders p p to be
delivered flat on a receiving table q as shewn or to folding mechanism as herein-
before mentioned.
Any of the usual well known or other convenient printing machinery appliances
may be employed for lowering and raising the impression cylinders on and off the
type, or for operating, adjusting, or regulating the several parts of the apparatus
herein referred to or shewn in the drawing.
The traverse of the type table must in all cases be in unison with the number of
impression cylinders constituting the set or series and the size of the sheet to be
printed. Thus, if there be four impression cylinders in each series (as shewn in
the drawing) the traverse of the continuous rack which actuates the type table
must equal the united lengths of the four sheets to be printed. If five impression
cylinders form the set then the traverse must equal the united lengths of the five
sheets and so on in combination as will be well understood.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The hereinabove described arrangement whereby paper from a continuous web
or roll is by a single passage through the machine printed successively at opposite
sides between flat type or stereotype and impression cylinders having their axes
arranged in a plane parallel to the flat table that carries such type or stereotype.
2. The machine for printing from flat type or stereotype both sides of the paper
from a continuous web or roll constructed arranged and operating as described with
reference to and shewn in the annexed drawing.
Dated this 24th day of July 1885.
