Improvements in and relating to Printing Machines.
I, WILLIAM EDWARD EVANS, of Lonsdale Chambers, 27, Chancery Lane, London,
W.C., Consulting Engineer, (being a communication from abroad by Henry
Alexander Wise Wood, of 1, Madison Avenue, New York, in the United States
of America, Manufacturer,) do hereby declare the nature of this invention to be as
follows:-
My invention relates to that class of printing machines which are known
as traveling cylinder web printing presses, and the object of my invention is
to provide an improved construction in which the web will have a very simple
and direct path of travel in such position that it will leave at least one of the
type forms so that the same will be readily accessible.
To these ends, my invention consists in the parts and combinations of parts
as hereinafter described.
The impression cylinders co-operate with respective stationary form beds and
are journalled in a suitable framing or carriage, which is guided upon suitable
ways carried by the side frame of the press.
At each side of each of the impression cylinders I provide suitable form
inking rollers which co-operate with a suitable ink-distributing apparatus in
order to properly ink the forms upon the stationary form beds.
Journalled in the side frames at one end of the press, I provide a web roll
from which the paper is led into the press between constantly running feeding-
in tapes.
The endless tapes pass over suitable tape rollers and are driven or actuated
as hereinafter described..
It will be understood that the web is led into the press, so that the feeding-in
devices are located below one of the stationary form. beds.
I consider this arrangement desirable, as it enables me to economize space, and
to form a compact machine, and by introducing the web into the press between
the two stationary beds, as will be hereinafter explained, it will be seen that
I am enabled to deliver the web directly from one end of the press.
From the constantly running feeding-in tapes, the web passes down under a
looping-in roller between the stationary form beds, up and around a guide
roller journalled in the side frames of the press, over and around a guide roller
journalled in the cylinder carriage, down under and around the first impression
cylinder over and around another guide roller also journalled in the cylinder
carriage, over and around a further guide roller journalled in the cylinder
carriage, over and around an adjustable register roll journalled in the side frames
of the press, over a guide roller journalled in the cylinder carriage at one side
of the second impression cylinder down under and around the impression
cylinder over and around a guide roller at the opposite side of the impression
evlinder under and around a guide roller journaled in the side frames over
the looping-out roller and over and around the constantly running feeding-out
roller.

page_text: This feeding-out roller co-operates with suitable endless tapes.
By providing this path of travel of the web, it will be seen that the impression
cylinder will be mounted substantially in a loop of the web, and it will also be
seen that when the impression cylinder travels to the right this loop of web
will be given up, and the web would become slack if it were not for one of the
guide rollers which forms a loop in the web, and takes up the same as fast as it
is given out on account of the motion of the impression cylinder or, in other
words, the impression cylinder and the guide roller referred to which moves
synchronously therewith, form a loop in the web, which may be shifted back and
forth without slackening the web or affecting the feeding in and delivery ends
thereof; and by this construction, it will be seen that when the impression
cylinder is at the right hand end of its travel, the web will be shifted from
over the form bed, which leaves the form bed easily accessible so that the forms
can be secured in place thereon.
I consider this construction a feature of importance, as in the ordinary forms
of travelling cylinder printing presses, the web is led over the form beds in
such position as to practically prevent access thereto, and in using this form
of press, it has heretofore been customary to secure the forms in place after the
web is threaded through the machine, which results in considerable delay in
the printing, owing to the difficulty in properly securing the forms on the bed.
This class of presses is, of course, ordinarily employed in printing newspapers,
and in my construction, one of the forms, which may be set up from standard
matter, is secured in place upon the second form bed.
The web is threaded through the machine the form to be secured upon the
first bed being kept open until the last minute, the last operation before
printing being simply to remove this form in place upon its bed which can
be almost instantly done, and I am enabled to commence the printing at once,
when the form has been secured in place, which, of course, is a feature of
importance in newspaper work, and of course this same saving is made when a
number of forms are placed abreast on each bed.
The gearing for driving the press may be arranged in any of the ordinary or
preferred manners for example fastened upon and turning with the power
shaft I provide pinions which mesh with and actuate driving gear wheels which
are secured upon a parallel shaft.
Suitable crank pins carried by the driving gear wheels are connected by pitmen
and actuate levers which vibrate upon a cross shaft.
These levers are connected with and drive the cylinder carriage by means
of suitable pitmen.
The constantly running feeding-in tapes may, if desired, be driven from one
of the driving gear wheels by means of a pinion which meshes with and drives
a gear fastened to the tape roller the gear in turn meshing with and driving
another gear secured to the second tape roller.
Actuated and driven from the power shaft by means of bevel gears I provide
a horizontal longitudinal shaft upon which I provide a bevel pinion which
meshes with and drives a bevel gear having a spur secured thereto, which meshes
with and drives another gear wheel for actuating the cam shaft journalled in
the side frames of the press.
Fastened upon and secured to the cam shaft are suitable cams which actuate
rollers journalled upon suitable levers which are connected by suitable pitmen
with bell crank levers which actuate the looping-in roller by means of pitmen
and to bell crank levers which actuate the looping-out roller by means of pitmen.
Actuated and driven from the horizontal longitudinal shaft by means of
bevel gears I provide a vertical shaft which in turn actuates and drives the con-
stantly running feeding out roller by means of bevel gears.
It is evident, however, that many different arrangements of gearing or driving
mechanism can be adopted without departing from the essence of my invention.
which relates particularly to the path of the web through the machine, and I

without departing from the broad scope of my invention.

Improvements in and relating to Printing Machines.
I, WILLIAM EDWARD EVANS, of Lonsdale Chambers, 27, Chancery Lane, London,
W.C., and 105 Colmore Row, Birmingham, Consulting Engineer, do hereby declane
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:-
My invention relates to that class of printing machines which are known
as travelling cylinder web printing presses, and the object of my invention is
to provide an improved construction in which the web will have a very simple
and direct path of travel in such position that it will leave at least one of the
type forms so that the same will be readily accessible.
To these ends my invention consists in the parts and combinations of parts
as hereafter described, and more particularly pointed out in the claims at the end
of this specification.
In the accompanying drawings, Fig. 1 is a side elevation of a printing machine
constructed according to my invention, and
Fig. 2 is a diagramatic sectional view of the same.
Referring to the drawings and in detail, C designates the first impression
cylinder which co-operates with a stationary form bed A; and I) designates the
second impression cylinder, which co-operates with a similar stationary form
bed B.
The impression cylinders C and D) are journalled in a suitable framing or
carriage E, which is guided upon suitable ways carried by the side frames 10
of the press.
At each side of each of the impression cylinders, I provide suitable form
inking rollers F, which co-operate with a suitable ink-distributing apparatus I,
in order to properly ink the forms upon the stationary form beds A and B.
Journalled in the side frames 10 at one end of the press, I provide a web
roll W from which the paper is led into the press between the constantly running
feeding-in tapes 15 and 16.
The endless tapes 15 pass over suitable tape rollers 11 and 13, and similar
endless tapes 16 pass over the tape rollers 12 and 14, the tapes being driven or
actuated as hereinafter described.
As shown in the drawings, it will be seen that the web is led into the press,
so that the feeding-in devices are located below one of the stationary form beds.
I consider this arrangement desirable, as it enables me to economize space,
and to form a compact machine, and by introducing the web into the press
between the two stationary beds, as will be hereinafter explained, it will be
seen that I am enabled to deliver the web directly from one end of the press.
From the constantly running feeding-in tapes, the web passes down under a
looping-in roller 17 between the stationary form beds, up and around a guide
roller 18 journalled in the side frames of the press, over and around a guide
roller 19 journalled in the cylinder carriage, down under and around the first
impression cylinder C, over and around a guide roller 20 also journalled in the

page_text: a bevel pinion 44, which meshes with and drives a bevel gear 45, having a
spur gear 46 secured thereto, which meshes with and drives a gear 47 for
actuating, the cam shaft 48, journalled in the side frames of the press as shown.
Fastened on and secured to the cam shaft 48 are suitable cams 49, which
actuate rollers journalled upon suitable levers 50 as shown. The levers 50 are
connected by suitable pitmen 51 with bell crank levers 52 which actuate the
looping-in roller 17 by means of pitmen 53, and to bell crank levers 54, which
actuate the looping-out roller 26 by means of pitmen 55.
Actuated and driven from the horizontal shaft shaft 43 by means of bevel
gears 56 and 57, I provide a vertical shaft 58, which in turn actuates and drives
the constantly running feeding-out roller 27, by means of the bevel gears 59
and 60.
It is evident, however, that many different arrangements of gearing or driving
mechanism can be adopted without departing from the essence of my invention
which relates particularly to the path of the web through the machine, and I am
aware that many changes may be made by those who are skilled in the art
without departing from the scope of my invention, as expressed in the claims.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination with two form beds, a travelling impression cylinder co-
operating with each form bed, web-guides adapted to read the web to the first
impression cylinder, a looping roller moving with the impression cylinders, to
which the web passes from the first impression cylinder, a stationary roll around
which the web then passes to the second impression cylinder, and a web manipu-
lating or feeding mechanism, substantially as described.
2. The combination of two form beds arranged in substantially the same
horizontal plane, a travelling impression cylinder co-operating with each form
bed, means for leading the web into the machine up between the form beds,
a looping roller moving with the impression cylinders to which the web passes
From the first impression cylinder, and around which the same is looped between
the two impression cylinders, a stationary roll interposed between the looping
oller and the second impression cylinder, and a web-manipulating or feeding
echanism, substantially as described.
3. The combination in a printing press of two form beds, a travelling impression
Beylinder co-acting with each form bed, web-guides comprising web-guides on
e frame, a looping roller moving with the impression cylinders interposed in
me path of the web between the two impression cylinders, and a stationary roll
terposed in the path of the web between the looping roller and the second
npression cylinder, means for adjusting this last named ro 1 whereby the same
3.ay act as a register-adjusting device, and a web-manipulating or feeding
anism, substantially as described.
4. A printing press constructed and operating in the manner and for the
rpose herein before described.
