PROVISIONAL SPECIFICATION.
Improvements in Rotary Web Printing Machines.
I GEORGE ASHLEY WILSON of Montague Villa, Broad Green, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
The object is to provide a machine for printing at once two webs of paper by
means of rotating cylinders in which the printing and impression cylinders and inking
mechanism is readily accessible and by which papers of various sizes such as papers
having say four, eight, twelve or sixteen pages may be readily printed and conducted
when required to folding mechanism.
Under the first part a pair of printing cylinders are disposed in the same horizontal
plane with their axis parallel to each other and with inking mechanism between:
beneath the said cylinders and in contact therewith are placed a pair of impression
cylinders. In the same horizontal plane as the impression cylinders and at a distance
therefrom are placed a second pair of printing cylinders, the impression cylinders
are between the said printing cylinders and are out of contact therewith; at the
opposite sides of the printing cylinders to that on which the impression cylinders are
placed inking mechanism is disposed; beneath the second pair of printing cylinders
and in contact therewith and with the first pair of impression cylinders are placed a
second pair of impression cylinders.
Web carriers are located in any convenient position near the first pair of printing
cylinders, and tapes are employed where necessary to convey the webs through
between the several printing and impression cylinders to a pair of delivery rollers.
Driving gear of usual construction is employed to give motion to the parts and change
gear is used to enable the printing mechanism for one web to be run at the same or
a different speed to the printing mechanism for the other web. For four page papers
the two printing cylinders for each web have duplicate type or stereotype. For eight
page papers the two cylinders for each web have complete type or stereotype for one
paper. For twelve page papers the two printing cylinders of one web have complete
type or stereotype for an eight page paper whilst the two printing cylinders of the
other web have repititions of type or stereotype for a four page paper and are run at
a reduced speed. For a sixteen page paper the printing cylinders of each web
produce a complete eight page paper having different contents and the said cylinders
are run at equal speeds. The papers printed on each web are brought by the tapes
to the delivery rollers whence they pass to cutting and folding mechanism of any
suitable kind or the cutting mechanism is disposed at a point in the machine between
the printing cylinders and delivery rollers.

COMPLETE SPECIFICATION.
Improvements in Rotary Web Printing Machines.
I, GEORGE ASHLEY WILSON, of Montague Villa, Broad Green, in the County of
Lancaster Engineer, 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 :-
The object is to provide a machine for printing at once two webs of paper by
means of rotating cylinders in which the printing and impression cylinders and

page_text: inking mechanism is readily accessible and by which papers of various sizes such as
papers having say four, eight, twelve or sixteen pages may be readily printed and
conducted when required to folding mechanism.
Machines under my invention are constructed as follows. A pair of printing
cylinders are disposed in the same horizontal plane with their axis parallel to each
other and with inking mechanism between; beneath the said cylinders and in contact
therewith are placed a pair of impression cylinders. In the same horizontal plane as
the impression cylinders and at a distance therefrom are placed a second pair of
printing cylinders; the impression cylinders are between the said printing cylinders
and are out of contact therewith; at the opposite sides of the printing cylinders to
that on which the impression cylinders are placed inking mechanism is disposed;
beneath the second pair of printing cylinders and in contact therewith and with the
first pair of impression cylinders are placed a second pair of impression cylinders.
In order that my invention may be readily understood I have appended an outline
drawing of my improved machine the various parts of which such as printing
inking impression cylinders, driving gear, carrying tapes are of usual construction.
a is the frame. 661 webs of paper to be printed. c c printing cylinders in the
same horizontal plane. d d'inking mechanism between the cylinders c c¹. e e¹ im-
pression cylinders beneath and in contact with the printing cylinders c c. ff
printing cylinders in the same horizontal plane as the impression cylinders e e¹.
9 glinking mechanism for the cylinders ff. h h impression cylinders in contact
with the cylinders e e² and ff. i tape carriers for conducting the webs bb to
rollers which deliver them to cutting and folding cylinders k of usual construction.
1 transverse folding mechanism. m cutting cylinders around which the web passes
when twelve page papers are being printed and the web b¹ is run at half the speed
of b.
For four
Web carriers are located in any convenient position near the first pair of printing
cylinders and tapes are employed where necessary to convey the webs through
between the several printing and impression cylinders to a pair of delivery rollers.
Driving gear of usual construction is employed to give motion to the parts and
change gear is used to enable the printing mechanisin for one web to be run at the
same or a different speed to the printing mechanism for the other web.
page papers two printing cylinders for each web have duplicate type or stereotype.
For eight page papers the two cylinders for each web have complete type or stereo-
type for one paper. For twelve page papers the two printing cylinders of one web
have complete type or stereotype for an eight page paper whilst the two printing
cylinders of the other web have repititions of type or stereotype for a four page
paper and are run at a reduced speed. For a sixteen page paper the printing
cylinders of each web produce a complete eight page paper having different contents
and the said cylinders are run at equal speeds. The papers printed on each web are
brought by the tapes to the delivery rollers whence they pass to cutting and folding
mechanism of any suitable kind or the cutting mechanism is disposed at a point in
the machine between the printing cylinders and delivery rollers.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
