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:-
The aim of this invention is to improve travelling cylinder web printing
presses, and consists in providing means so that a single web or a plurality of
webs can be run through such printing couple or couples, and different lengths
or numbers of forms used for each web, producing a different product from
each web.
To do this, I provide separate web-manipulating mechanisms for each web,
and make each web-manipulating mechanism adjustable.
I also make one or more of the web-manipulating mechanisms extend across
the press so that the web, the width of the machine, may be manipulated.
may be
Thus a traveling cylinder web press arranged after my invention
used for a single width of web up to the extent of the machine, adjusted to get
any desired length of sheet, or for a plurality of webs side by side, from each
of which webs, sheets of any desired length within the range of the machine can
be produced.
It will be seen that all these changes and adjustments can be made simply in
the manipulating devices for the web, and that the printing mechanism does
not have to be adjusted or altered in any degree, no matter whether one or more
webs are used, and no matter what length or width of sheet is produced.
In the class of web printing presses to which I have referred, the width of the
sheet can be varied by varying the width of the web used, and of course a plurality
of webs could be used in the ordinary machine, but, as before explained, I have
provided a separate web-manipulating mechanism for each of a plurality of webs,
and I preferably make each web-manipulating mechanism adjustable, so that by
varying the length of the forms used, the length of the sheets of each web can
be varied.
This enables me to obtain a full width product upon a single web of any
desired width, or a product of any desired length and width, within the limits of
the machine, upon each of a plurality of webs.
I will now describe the machine which has been chosen to illustrate one specific
application of my invention.
Arranged between the two side frames of the machine in any desired relative
location, are two type beds and these beds, are arranged horizontally, and one
Lawn the other

page_text: Two travelling impression cylinders co-operate with the beds and are mounted
in reciprocating carriers mounted on guides arranged on the side frames, the
arrangement of these parts being well understood.
At each side of each impression cylinder may be arranged a form inking roller
and any suitable inking apparatus may be used, so that the forms will be properly
inked for each impression, the details of the inking apparatus not being neces-
sary here to discuss at length.
It will be understood that at the ends of the side frames are arranged bearings
in which two web rolls can be mounted.
In the press are arranged two manipulating mechanisms. By the term "web
manipulating mechanism," I mean to include broadly any suitable mechanism
that will manipulate the web.
"
By the term "feeding mechanism," I mean to include either the mechanism
which feeds the web into and out of the, press as designated, and by the term
web shifting mechanism," I mean to include the mechanism which gives the
web its proper movement while the printing mechanisms are not in impression.
It will be understood that two independent web-printing manipulating
mechanisms, may be provided each consisting of a continuously running feeding-
in and feeding out mechanism for the web, acting, in conjunction with each of
which is a web shifting mechanism, which will respace the web or webs around
the cylinder or cylinders while the printing mechanism is out of impression.
These two web-manipulating mechanisms are practically independent of each
other, and each is made adjustable as hereafter described, so that the length of
sheet printed on each web can be varied, as desired.
The first web-manipulating mechanism consists of the continuously running
feeding in rollers a looping roller and a guide roller, and the parts hereafter
described.
From the first guide roller the web passes to a guide mounted in the carriers
underneath the lower impression cylinder then up over another guide also carried
by the carriers.
From this last guide the web passes to a stationary guide or roll up over an
adjustable register roll then around a guide carried by the carriers, underneath
the upper impression cylinder around another guide or roll also carried by
the reciprocating carriers.
From this last guide or roll the web passes to a stationary guide or roll up
over a looping roller and then may be delivered by any suitable delivery mechan-
ism such as continuously running rollers.
This web-manipulating mechanism is preferably made to extend the full width
of the press so that any width of web within the full limit of the machine can
be led through the press and handled in it.
This web-manipulating mechanism is also made adjustable so that if desired,
any length of sheet can be printing on the web.
It will, be understood that both the loopers of this web-manipulating mechan-
ism are arranged so that the loopers have their ends away from each other.
The second-web-manipulating mechanism consists of a series of three con-
tinuously running feeding-in rollers, a looping feeding-in roller, and a guide or
roll to which the web is led from the looping roller."
From the guide or roll aforesaid the web passes around the guide under the
lower impression cylinder up over the second guide carried by the cylinder
carriers. From this guide or roll the web manipulated by the second web mani-.
pulating mechanism, passes up over another guide to an adjustable registering
roll. From this point, the web carried by the second web manipulating mechan-
ism passes over the guide under the upper impression cylinder up over the second
guide carried by the cylinder carriers.
From this point, the web passes to a stationary guide or roll under a looping
roller and then to any suitable delivery mechanism, such as a series of con-
tinuously running rollers.

page_text: It will be understood that the loopers of this second web-manipulating mechan-
ism are so arranged that the points or ends of the loops will face each other.
The second web-manipulating mechanism is also preferably extended the
entire width of the press, and is also preferably made adjustable.
By the peculiar arrangement of loopers pointed out, it will be understood that
the loopers of one web manipulating mechanism will not strike or interfere with
the web carried by the other web-manipulating mechanism.
The gearing for driving the various apparatus before referred to may be
arranged as follows:-
Each of the carriers may have a wrist-pin arranged therein, and a link or pit-
man may connect the same to crank pins carried by crank-gears which are
mounted on the ends of a shaft journalled in suitable bearings in the side frames.
The driving shaft may have tight and loose pulleys arranged thereon, by which
means power may be applied to operate the machine.
On each end of the driving shaft is arranged a pinion the front pinion of
which meshes with a gear which is mounted on the end of a transverse shaft
and this gear meshes with and drives the front crank-gear before referred to.
The pinion or gear on the rear end of the driving shaft meshes with and
drives a gear mounted on the back end of another transverse shaft and this gear
meshes with and drives the rear crank gear before referred to.
The ratio between the gears is preferably made two to one, so that the web-
manipulating mechanisms will properly act so that the web or webs will be
shifted or respaced when the cylinder or cylinders is or are out of impression at
either end of the bed or beds.
By the gearing before described, the impression cylinders will be moved
forwards and backwards over the form beds. The gearing for driving the web
manipulating mechanism first described may be arranged as follows:
The end of the transverse shaft in gear with the driving shaft and furthest
from the beds on what I term the front side of the press is arranged to receive
a change cam and gear, which parts constitute a single piece, which may be
held in place on the end of the shaft by means of a suitable key and nut, the
gear aforesaid and a hub extending into the cam and these two parts are
rigidly fastened together. As many of these change gears and cams are pro-
vided as it is desired to obtain various lengths of sheets from this first web-
manipulating mechanism, and it will be seen from the description which here-
after follows, that all that is necessary to vary the length of the sheet mani-
pulated by this first web-manipulating mechanism is to vary or change this
single piece or part.
A transverse shaft is provided in proximity to the change cam and gear
immediately above referred to on the front end of which is mounted an arm
which carries a roll which bears on the change cam. Mounted on this same
transverse shaft are arms which connect by suitable links to blocks which are
mounted in suitable guide-ways in the frames.
These blocks carry the looping rollers of the first web-manipulating mechan-
ism, and suitable springs may be used to keep the roller properly in engagement
with the cam.
A suitable sweep, is suitably mounted on the side of the machine and carries
an intermediate gear which is adapted to mesh with the change gear and by
setting the sweep, the intermediate gear can be made to wesh with various sized
gears.
The sweep is mounted on a shaft which is journalled in a bracket mounted
in the frame and also mounted on this shaft is another gear which is in constant
engagement with the intermediate gear. Also arranged on this shaft is a bevel
gear which meshes with another bevel-gear fastened on the lower end of a
vertical shaft mounted in suitable bearings on the frame. From this vertical
shaft, the continuously running feeding-in rollers may be driven by means of

page_text: bevel gears and also the continuously running delivery rollers may be driven
as by means of the bevel gears.
By this means, it will be seen that the web-manipulating mechanism is con-
trolled by the single change piece, and that by varying this single change piece
the speed of the continuously feeding-in and continuously feeding-out rollers,
and the action of the loopers are properly varied so that the length of the sheet
manipulated by this first manipulating mechanism may be quickly and readily
adjusted by changing this single piece.
The gearing for driving and adjusting the second web-manipulating mechan-
ism is substantially like that described in connection with the first manipulating
mechanism, and is arranged at the back of the press.
On the rear end of the second transverse shaft in gear with the driving shaft
is fitted a change gear and cam which may be held in place by a nut and which
is arranged substantially like the change gear and cam of the first web-mani-
pulating mechanism.
A further transverse shaft is provided on the end of which is arranged an arm
which carries a roll bearing on the change cam of the second transverse shaft
referred to. Also arranged on the former shaft are arms which connect by suitable
links or connections to blocks mounted in suitable bearings in the frames, and
which blocks carry the looping, rollers and by this means, the loopers of the
second web-manipulating mechanism will be properly actuated.
A suitable sweep, is provided in connection with the second web-manipulating
mechanism and carries an intermediate gear which by setting the sweep, is
adapted to mesh with the change-gear.
This sweep is mounted on a shaft which is journalled in a bracket mounted in
the side frame and mounted on this shaft is a gear which is in constant mesh and
engagement with the intermediate gear.
By this means, any desired change gear can be used and by setting the sweep, it
can transmit motion to the second continuously running feeding-in and feeding-
out mechanisms.
Also arranged on the shaft upon which the sweep last mentioned is mounted
is a bevel pinion which meshes with and drives a bevel pinion arranged on a ver-
tical shaft and from this vertical shaft the constantly running feeding-in rollers
of the second manipulating mechanism may be driven by means of bevel gears
and the second continuously running feeding-out mechanism may be also driven
by means of bevel gears.
Thus, the second web-manipulating mechanism can be adjusted for any
desired length of sheet.
The registering roll of the first web-manipulating mechanism is mounted in
suitable blocks which are mounted in ways in the frames and these blocks have
racks, engaging which are pinions arranged on a transverse shaft journalled in
the frames. Engaging one of these pinions is a worm which may be manipulated
by any suitable means, and by this means the registering roll can be adjusted.
The registering roll of the second web-manipulating mechanism is mounted
in blocks which also run in ways. These blocks have teeth which engage pinions
arranged on a transverse shaft. Engaging one of these pinions is a worm which
may be manipulated in any suitable way, and by this means the registering roll
can be properly adjusted.
By this means it will be seen that the registering roll of each web manipulating
mechanism can be adjusted independently of the other.
By the arrangements thus described, it will be seen that the press can be
arranged for a great variety of work. For instance, a full width web can be
carried through the machine, and manipulated either by the first or second set
of web-manipulating mechanism, as desired, and if desired, when only one
web manipulating mechanism is in use the other web-manipulating mechanism
can be rendered inoperative by removing the change gear and cam of the same.

page_text: When only a single web is used, in the machine, the same can, of course, be
made of any width desired, and any length of sheet can be printed by adjusting
the change gearing.
Further, it will be seen that two independent webs can be led through the
machine, and each manipulated by one of the web-manipulating mechanisms.
The width of these webs can be made as desired, provided the sum of the
same is not greater than the total width of web that can be run through the
machine; for instance, a one quarter width web and a three quarter width web
may be used; a one-third width web and a two-third width web may be used,
or each web may be made of one-half the capacity of the press.
Further, it will be seen that the length of sheet produced on either web
can be easily adjusted by the gearing before described.
The two webs need not necessarily be of such added width as to equal the full
capacity of the machine; they may be of any width provided the added widths
do not exceed the full capacity of the machine.
The web led from the highest web-roll may be wider than the web led from
the lower web-roll. The former web is led through the parts I have termed the
second web-manipulating mechanism, and the latter web is led through the
parts I have termed the first web-manipulating mechanism.
This arrangement greatly increases the capacity of presses of the class
described, for many times it is desired to have independent lengths; and further,
this arrangement does not interfere with the press being used to print on a
single web, which can be made of any width up to the capacity of the machine.
The relative arrangements of the printing mechanisms may be greatly varied
and departed from, the same not being essential to my invention.
The feeding mechanisms are not necessarily continuous feeding-in and feed-
ing-out mechanisms, as intermittent devices could be substituted therefor, and
still come within the scope of my invention.
Any system of gearing that will give preferably a various length of sheet, as
desired, can be used without departing from the scope of my invention.
"
As I have used the term "web manipulating device" or web manipulating
mechanism in this specification I mean to include by the same, any mechanism
that will properly manipulate and control the web in the machine, and where
I have used the term "web feeding device," I have reference to the machine
that either feeds the web into or out of the press, or which performs both of
these operations; and when I have used the term web-shifting device," I
have reference to the mechanism which gives the web its intermittent action.
By this terminology or momenclature, it will be seen that the term "web
manipulating device, covers any mechanism which will control and properly
manipulate a web.
Many other forms of web-manipulating mechanisms, besides that described, are
known, and can be used without departing from the scope of my invention.
The details and arrangements herein described may be greatly varied by a
skilled mechanic without departing from the scope of my invention.

I, WILLIAM EDWARD EVANS, of Lonsdale Chambers, 27, Chancery Lane, London,
W.C., and 105, Colmore Row, Birmingham, Consulting 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 aim of this invention is to improve travelling cylinder web printing
presses; and the same consists in providing means so that a single web or a
plurality of webs can be run through such printing couple or couples, and
different lengths or numbers of forms used for each web, producing a different
product from each web.
To do this, I provide separate web-manipulating mechanisms for each web
and make each web-manipulating mechanism adjustable.
I also make one or more of the web-manipulating mechanisms extend across
the press so that the web, the width of the machine, may be manipulated.
Thus a travelling cylinder web press arranged after my invention may be
used for a single width of web up to the extent of the machine, adjusted to get
any desired length of sheet, or for a plurality of webs side by side, from each
of which webs, sheets of any desired length within the range of the machine can
be produced.
It will be seen that all these changes and adjustments can be made simply
in the manipulating devices for the web, and that the printing mechanism
does not have to be adjusted or altered in any degree, no matter whether one
or more webs are used, and no matter what length or width of sheet is produced.
Referring to the drawings, which illustrate a machine arranged after my
invention,
Fig. 1 is a plan view of the general arrangement,
Fig. 2 is a side elevation,
Fig.
is a detail illustrating the interchangeable part for varying the length
of the sheets,
Fig. 4 is a section taken on the line 4-4 of Fig. 1, and
Fig. 5 is a side elevation from the opposite side relatively to Fig. 2.
In the class of web printing presses to which I have referred, the width of the
sheet can be varied by varying the width of the web used, and of course a
plurality of webs could be used in the ordinary machine, but, as before explained,
I have provided a separate web-manipulating mechanism for each of a plurality
of webs, and I preferably make each web-manipulating mechanism adjustable,
so that by varying the length of the forms used, the length of the sheets of
each web can be varied.
This enables me to obtain a full width product upon a single web of any desired
width, or a product of any desired length and width, within the limits of the
machine upon each of a plurality of webs.
Referring now to the drawings and in detail, I will now describe the machine
which has been chosen to illustrate one specific application of my invention
In detail A and B represent two side frames of any desired shape.
Arranged between these two side frames in any desired relative location are
two type beds as C and D, and these beds as specifically shown are arranged hori-
zontally, and one above the other.
Co-operating with the bed C is a travelling impression cylinder E, and co-
operating with the bed D is the travelling impression cylinder F, these two
impression cylinders being mounted in the reciprocating carriers H which carriers

page_text: are mounted on guides I arranged on the side frames, the arrangement of these
parts being well understood.
At each side of each impression cylinder may be arranged a form inking
roller G, as shown, and any suitable inking apparatus may be used, so that the
forms will be properly inked for each impression, the details of the inking appara-
tus not being necessary here to show and discuss at length.
It will be seen that at the ends of. the side frames are arranged bearings in
which two web rolls can be mounted.
In the press are arranged two manipulating mechanisms. By the term "web-
manipulating mechanisın" I mean to include broadly any suitable mechanism
that will manipulate the web. By the term feeding mechanism," I mean to
include the mechanism which feeds the web into and out of the press as desig-
nated, and by the term "web shifting mechanism," I mean to include the
mechanism which gives the web its proper movement while the printing mechan-
isms are not in impression.
It will be seen that in the arrangement shown, I have provided two indepen-
dent web-manipulating mechanisms, each consisting of a continuously running
feeding-in and feeding-out mechanism for the web, acting in conjunction with
each of which is a web shifting mechanism, which will respace the web or
webs around the cylinder or cylinders while the printing mechanism is out of
impression. These two web-manipulating mechanisms are practically indepen-
dent of each other, and each is made adjustable as hereafter described, so that
the length of sheet printed on each web can be varied as desired.
The first web-manipulating mechanism consists of the continuously running
feeding-in rollers 10, 11, and 12, the looping roller 13, and the guide roller 14,
and the parts hereafter described.
From the guide roller 14, the web passes to the guide 15, mounted in the
carriers H underneath the impression cylinder E, then up over the guide 16,
also carried by the carriers. From this guide 16 the web passes to a stationary
guide or roll 17 up over the adjustable register roll 18, then around the guide 19
carried by the carriers underneath the impression cylinder F, around the guide or
roll 20 also carried by the reciprocating carriers H.
From the guide or roll 20, the web passes to the stationary guide or roll 21,
up over the looping roller 22, and then may be delivered by any suitable delivery
mechanism, such as the continuously running rollers, 23, 24, and 25.
This web-manipulating mechanism is preferably made to extend the full width
of the press so that any width of web within the full limit of the machine can
be led through the press and handled by the same.
This web-manipulating mechanism is also made adjustable so that if desired,
any length of sheet can be printed on the web.
It will be seen that the loopers 13 and 22 of this web-manipulating mechanism
are arranged so that the loops are formed away from each other.
The second web-manipulating mechanism will now be described.
26, 27, and 28 represent continuously running feeding-in rollers, 29 a looping
feeding-in roller, and 30 a guide or roll to which the web is led from the
looping roller 29.
From the roller 30 the web passes around the guide 15 under the lower impres-
sion cylinder E up over the guide 16. From the guide or roll 16, the web
manipulated by the second web manipulating mechanism passes up over the
guide 31 to the adjustable registering roll 32. From this point, the web carried
by the second web manipulating mechanism passes over the guide 19 under the
impression cylinder F, up over the guide 20. From this point the web passes
to the stationary guide or roll 33 under the looping roller 34, and then to any
suitable delivery mechanism as the continuously running rollers 35, 36, and 37.
It will be seen that the loopers 29 and 34 of this second web-manipulating
mechanism are so arranged that the loops will face each other.

page_text: The second web-manipulating mechanism is also preferably extended the entire
width of the press, and is also preferably made adjustable.
By the peculiar arrangement of loopers pointed out, it will be seen that the
loopers of one web manipulating mechanism will not strike or interfere with
the web carried by the other web-manipulating mechanism.
The gearing for driving the various apparatus before referred to may be
arranged as follows:-
Each of the carriers H may have a wrist-pin 39 arranged therein, and a link
or pitman 38 connects the same to crank pins 40 carried by the crank gears 41,
which are mounted on the ends of the shaft 42, journalled in suitable bearings
in the side frames.
43 represents a shaft, which may be made the driving shaft of the machine,
and which may have tight and loose pulleys 44 and 45 arranged thereon, by
which means power may be applied to operate the machine.
On each end of the shaft 43 is arranged a pinion 46 the front pinion of which
meshes with a gear 47 which is mounted on the end of a transverse shaft 48, and
this gear 47 meshes with and drives the front crank gear 41.
The pinion or gear 46 on the rear end of the shaft 43 meshes with and drives
a gear 75 mounted on the back end of the transverse shaft 148, and this gear 75
meshes with and drives the rear crank gear 41.
The ratio between the gears 41, 47 and 75 is preferably made two to one, so
that the web-manipulating mechanisms will properly act so that the web or webs
will be shifted or re-spaced when the cylinder or cylinders is or are out of impres-
sion at either end of the bed or beds.
By the gearing before described, the impression cylinders will be moved
forwards and backwards over the form beds. The gearing for driving the web-
manipulating mechanism first described may be arranged as follows:-
:
The end of the shaft 48, on what I may term the front side of the press is
arranged to receive a change cam and gear 49 and 50, which parts constitute a
single piece, which may be held in place on the end of the shaft 48 by means of
a suitable key and nut 51, a hub 52 on the gear 50 extending into the cam 49,
as shown in Figure 3, and these two parts viz. the gear and cam are rigidly
fastened together. As many of these change gears and cams are provided as it
is desired to obtain various lengths of sheets from this first web-manipulating
mechanism, and it will be seen from the description which hereafter follows, that
all that is necessary to vary the length of the sheet manipulated by this first web-
manipulating mechanism is to vary or change this single piece or part.
53 represents a transverse shaft on the front end of which is mounted an arm
54, which carries a roll 55, which bears on the cam 49. Also mounted on this
shaft 53 are arms 540 and 61, which connect by suitable links as 56 to a block 57,
which is mounted in suitable guide-ways 58 in the frames, and also to blocks 60
which are mounted in suitable ways 59 in the frames.
These blocks 57 and 60 carry the looping rollers 13 and 22 of the first web-
manipulating mechanism, and suitable springs 560 may be used to keep the
roller 55 properly in engagement with the cam.
62 represents a suitable sweep, which carries an intermediate 63 which is
adapted to mesh with the gear 50, and by setting the sweep the gear 63 can be
made to mesh with various sized gears 50.
The sweep 62 is mounted on a shaft 65 which is journalled in a bracket 66
and in the frame A, and also mounted on this shaft 65 is a gear 64, which is in
constant engagement with the intermediate 63. Also arranged on this shaft 65
is a bevel-gear 67 which meshes with a bevel-gear 68 fastened on the lower end
of a vertical shaft 69 mounted in suitable bearings on the frame A as shown.
From this vertical shaft, the continuously running feeding-in rollers 10, 11, and 12
may be driven by means of bevel-gears 70 and 71, and also the continuously
running delivery rollers may be driven as by means of the bevel gears 72 and 73.
By this means it will be seen that the web-manipulating mechanism is con-

page_text: trolled by the single change piece, and that by varying this single change piece
the speed of the continuously feeding-in and continuously feeding-out rollers
and the action of the loopers are properly varied so that the length of the sheet
manipulated by this first manipulating mechanism may be quickly and readily,
adjusted by changing this single piece.
The gearing for driving and adjusting the second web-manipulating mechan-
ism is substantially like that described in connection with the first manipulating
mechanism, and is arranged at the back of the press, as shown in Fig. 5.
On the rear end of the shaft 148 is fitted a change gear and cam 76 and 77,
which may be held in place by a nut 78, and which are arranged substantially
like the change gear and cam 50 and 49 of the first web manipulating mechanism.
79 represents a transverse shaft, on the end of which is, arranged an arm 80,
which carries a roll 81 bearing on the change cam 77. Also arranged on this
shaft 79 are arms 800 and 860, which connect by suitable links or connections 83
to blocks 84 mounted in suitable bearings 85 in the frames, and which blocks
carry the looping rollers 29 and 34, and by this means the loopers of the second
web-manipulating mechanism will be properly actuated.
Suitable springs 830 may be arranged to keep the roller 81 against the cam, as
shown.
87 represents a suitable sweep, which carries an intermediate 86 which inter-
mediate by setting the sweep is adapted to mesh with the change-gear 76.
This sweep is mounted on a shaft 121, which is journalled in a bracket 120
and in the side frame B, and mounted on this shaft is a gear 88 which is in con-
stant mesh and engagement with the intermediate 86.
By this means any desired change gear 76 can be used, and by setting the
sweep it can transmit motion to the second continuously running feeding-in and
feeding-out mechanisms.
Also arranged on the shaft 121 is a bevel pinion 89 which meshes with and
drives a bevel pinion 90 arranged on a vertical shaft 91, and from this vertical
shaft 91 the constantly running feeding-in rollers of the second manipulating
mechanism may be driven by means of the bevel-gears 92 and 93, and the second
continuously running feeding-out mechanism may be driven by means of the
bevel gears 94 and 95.
Thus the second web-manipulating mechanism can be adjusted for any desired
length of sheet.
The registering roll 18 of the first web manipulating mechanism is mounted
in suitable blocks 106 which are mounted in ways 101 in the frames A and B,
and these blocks 106 have racks 107, engaging which are pinions 108 arranged
on a transverse shaft 109, journalled in the frames. Engaging one of the.
pinions 108 is a worm 110, which may be manipulated by any suitable means,.
and by this means, the registering roll 18 can be adjusted."
The registering roll 32 of the second web-manipulating mechanism is mounted
in blocks 100, which also run in the ways 101. These blocks have teeth 102
which engage pinions 103 arranged on the transverse shaft 104.
Engaging one of these pinions 103 is a worm 105, which may be manipulated
in any suitable way, and by this means, the registering roll 32 can be properly
adjusted.
By this means it will be seen that the registering roll of each web-manipulat-
ing mechanism can be adjusted independently of the other.
By the arrangement thus described, it will be seen that the press can be
arranged for a great variety of work. For instance, a full width web can be.
carried through the machine, and manipulated either by the first or second set
of web-manipulating mechanisms, as desired, and if desired, when only one web
manipulating mechanism is in use the other web-manipulating mechanism can
be rendered inoperative by removing the change gear and cam of the same.
When only a single web is used in the machine, the same can, of course.

page_text: be made of any width desired, and any length of sheet can be printed by adjusting
the change gearing.
Further, it will be seen that two independent webs can be led through the
machine, and each manipulated by one of the web-manipulating mechanisms.
The width of these webs can be made as desired, provided the sum of the
same is not greater than the total width of web that can be run through the
machine; for instance, a one-quarter width web and a three-quarter width web
may be used; a one-third width web and a two-third width web may be used, or
each web may be made of one-half the capacity of the press. Further, it will
be seen that the length of sheet produced on either web can be easily adjusted
by the gearing before described.
The two webs need not necessarily be of such added width as to equal the full
capacity of the machine; they may be of any width provided the added widths
do not exceed the full capacity of the machine.
As shown the web w led from the highest web-roll W2 is wider than the web w
led from the web-roll W. The web is led through the parts I have termed
the second web-manipulating mechanism, and the web w¹ is led through the parts
I have termed the first web-manipulating mechanism.
This arrangement greatly increases the capacity of presses of the class described,
and further, this arrangement does not interfere with the press being used to
print on a single web, which can be made of any width up to the capacity of
the machine.
The relative arrangements of the printing mechanisms may be greatly varied
and departed from, the same not being essential to my invention.
The feeding mechanisms are not necessarily continuous feeding-in and feeding-
out mechanisms, as intermittent devices could be substituted therefor, and still
come within the scope of my invention.
Any system of gearing that will give preferably a various length of sheet, as
desired, can be used without departing from the scope of my invention.
As I have used the term "web manipulating device," or "web manipulating
mechanism in this specification, and accompanying claims, I mean to include
by the same any mechanism that will properly manipulate and control the
web in the machine, and where I have used the term "web feeding device," I
have reference to the mechanism that either feeds the web into or out of the
press, or which performs both of these operations; and when I have used the
term web-shifting device," I have reference to the mechanism which gives the
web its intermittent action.

By this terminology or nomenclature, it will be seen that the term "web
manipulating device," covers any mechanism which will control and properly
manipulate a web.
Many other forms of web-manipulating mechanisms, besides that shown are
known, and can be used 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 in a web printing press of a form bed, a travelling impres-
sion cylinder co-acting therewith, guides whereby a full width web or two inde-
pendent webs can be led through the machine, two web-manipulating devices,
and means whereby the same may be set so that a different length of sheet can
be produced on each web when two webs are run through the machine without
changing or altering the printing mechanism, substantially as described.
2. The combination in a web printing press of two form beds, a travelling
impression cylinder co-acting with each form bed, guides whereby a full-width
web or two independent webs can be led through the printing couples, two web-
manipulating devices, and means whereby the same may be set so that a different

page_text: length of sheet can be produced on each web when two webs are run through
the machine without changing or altering the printing mechanism, substantially
as described.
3. The combination in a web printing press of a form bed, a travelling impres-
sion cylinder co-operating therewith, guides whereby two independent webs can be
led through the machine, a web-manipulating device for each web, and means
whereby the lengths of the sheets printed on each web can be varied, substantially
as described.
4. The combination in a web printing press of two form beds and two travelling
impression cylinders, guides whereby two webs can be led through the printing
couples, a separate web-manipulating device for each web, and means whereby
the lengths of sheets printed on each web can be varied, substantially as described.
5. The combination in a web printing press of two form beds, a travelling im-
pression cylinder co-acting with each form bed, guides whereby two independent
webs can be led through the printing couples, and a separate web-manipulating
device for each web extending the full width of the machine, substantially as
described.
6. The combination in a web printing press of two form beds, a travelling im-
pression cylinder co-acting with each form bed, guides whereby two independent
webs can be led through the printing couples, separate web-manipulating devices
for each web extending the full width of the machine, and means for adjusting
each web-manipulating mechanism, substantially as described.
7. The combination in a web printing machine of the class described of two
independent web-manipulating mechanisms each comprising a feeding-in and
feeding-out mechanism, and a web shifting device composed of two loopers, the
loops of one manipulating device feeding oppositely or turned oppositely from
the loops of the other web-manipulating mechanism, substantially as described.
8. The combination with a web printing press of the class described of two
web-manipulating devices, each extending the entire width of the machine, and
a registering roll for each manipulating mechanism also extending the full width
of the machine, substantially as described.
9. The combination in a web printing press of a form bed, a travelling impres-
sion cylinder co-acting therewith, guides whereby two independent webs can be
led through the machine, and two manipulating devices, each consisting of con-
tinuously running feeding-in rolls and continuously running feeding-out rolls,
two loopers, and means for properly actuating the loopers, substantially as
described.
10. The combination in a web printing press of two form beds, a travelling
impression cylinder co-acting with each form bed, guides whereby two inde-
pendent webs can be led through the printing couples, separate web-manipulat-
ing devices for each web extending the full width of the machine, each consist-
ing of means for continuously feeding the web into and out of the press, two
loopers, and means for properly actuating the loopers, substantially as described.
11. A web printing press constructed and operating in the manner and for the
purpose herein before described.
