PROVISIONAL SPECIFICATION.
Improvements in connection with the Art of Printing.
We, GEORGE HENRY BAMBER, and THOMAS WARBURTON, both of 77 Sack-
ville Street, Manchester, in the County of Lancaster, Lithographic Printers, do
hereby declare the nature of this invention to be as follows:-
66
Our invention relates to improvements in the process known at present as
lithographic roll printing" in which blanks or designs are repeated at certain
regular or irregular intervals on a roll of paper or other suitable material by
continuous printing in a lithographic printing press.
The chief feature of our improvements consists in dispensing with the lithographic
printing press and in substituting for it a letterpress printing machine preferably a
platen machine slightly altered and adapted for the purpose.
In carrying our improvements into effect we so arrange and mount the machine
that we are enabled to lead the paper from a batch or roll into the machine and
draw it on to the platen where it is printed by the forme, and after leaving the
platen the printed paper is guided out of the machine and preferably back under
the unprinted roll and again batched on a roller or otherwise. The forme has
with
special pieces of rule fixed in it which print the margin of the paper
registration marks and on the platen are mounted suitable guides by means
of which the paper is held securely whilst being printed and is guided whilst
being drawn forward by the attendant to bring an unprinted surface on to the
platen these guides being a very important aid to uniform and accurate
registration.

Improvements in connection with the Art of Printing.
We, GEORGE HENRY BAMBER and THOMAS WARBURTON, both of 77 Sack-
ville Street, Manchester, in the County of Lancaster, Lithographic Printers, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
Our invention relates to improvements in the process known at present as
"lithographic roll printing" in which blanks or designs are repeated at certain
regular or irregular intervals on a roll of paper or other suitable material by
contiunous printing in a lithographic printing press.
The chief feature of our improvements consists in dispensing with the lithographic
printing press and in substituting for it a letterpress printing machine preferably a
platen machine slightly altered and adapted for the purpose.
In carrying our improvements into effect we so arrange and mount the machine
that we are enabled to lead the paper from a batch or roll into the machine and

page_text: draw it on to the platen where it is printed by the forme, and after leaving the
platen the printed paper is guided out of the machine and preferably back under
the unprinted roll and again batched on a roller or otherwise.
In the accompanying sheet of drawings-
Figure 1 is a side elevation, partly in section, of a platen letterpress printing
machine altered and adapted for the purposes of our invention.
Fig. 2 is a front view of the forme, and
Figs. 3, 4 and 5 are detail views of the guides for the paper.
In these views, a designates the frame of the machine, b the first motion shaft
from which the crank disc c is driven, d the platen which is actuated by a cam,
not shown, and swivels on the centre e from the position shown in full lines to that
indicated in dotted lines and vice versa, f the reciprocating forme carrier which is
rocked on the centre o by means of a connecting rod from the crank pin on the
disc i the inking rollers which travel over and ink the forme and are supplied
with ink from the pad j.
All the foregoing parts are of the ordinary construction and their arrangement
and mode of operation in a platen letterpress printing machine is well known and
understood.
For the purposes of our invention the paper k is batched on a roller and led into
and through the machine over and under guide rollers m passing over the table n
to the roller o on which it is batched. The paper k is printed whilst on the
platend when the latter is in the position indicated by dotted lines and when the
forme carrier has been moved forward into contact with it by means of
the connecting rod h. The forme p has special pieces g of rule fixed in it which
g.
print the margin of the paper with registration marks whilst the forme p prints the
required blank or design, and on the platen d are mounted guides & with adjustable
side guides t, shown detached in Figs. 4 and 5, by means of which the paper k is
held securely whilst being printed and is guided whilst being drawn forward by the
attendant at the front of the machine to bring an unprinted surface on to the
platen d, these guides s and t in conjunction with the registration marks printed
on the paper by the pieces of rule q being a very important aid to uniform and
accurate registration.
The paper after being printed is drawn forward by the attendant and as it leaves
the platend passes downward and guided by the rollers mis drawn by another attendant
at the back of the machine on to the table n where the lines printed by the forme p
are bronzed or otherwise treated if required and the printed paper is finally batched
on the roller o.
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. Improving the process of printing rolls of paper with blanks or designs
at certain intervals by adapting and utilizing a modified form of platen
letterpress printing machine substantially as herein described and illustrated
in substitution for the lithographic printing press commonly employed for this
purpose.
2. In a platen letterpress printing machine the special pieces of rule fixed in
the forme to print registration marks on the margin of the paper in combination
with a platen having adjustable guides for the roll of paper for the purpose of
insuring accurate registration in a process of continuous roll printing substantially
as herein set forth.
