Improvements in Rotary Web Printing Machines and Collecting and
Folding Mechanisms connected therewith.
I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, London, W.C.,
Consulting Engineer, (a communication from The Campbell Printing Press and
Manufacturing Company, corporation organised under the laws of the State of
New York, of 1, Madison Avenue, City, County, and State of New York, U.S.
America, Manufacturers), do hereby declare the nature of this invention to be
as follows:-
The object of the improvements hereinafter described is to simplify and facilitate
the operations in a rotary web printing press and folding machine, so that the
same may be run much faster and better than at present, and so that the folded
products can be very rapidly delivered.
The first improvement relates to a mechanism by which the fresh web-roll or
spool can be introduced into the machine without losing time.
The invention consists in providing means whereby the end of the fresh
web can be attached to the web in the machine, and this means is preferably
arranged so that this operation can take place without stopping the printing
machine.
Means are also provided so that, as the fresh web is started in, the web in the
machine will be cut off from the expiring web roll.
The means to accomplish these functions consist in brackets in which the fresh
web-roll can be temporarily placed, and of a knife or tucker preferably having
pins to which the end of the fresh web is secured.
A drawing-in device, consisting of a cylinder and a number of coacting tapes
is used to draw the web from the web-roll, and this tucker or blade is arranged so
as to strike up in between the cylinder and the tapes.
When the end of the web is secured to the tucker, a line of paste is applied
thereto.
When the web-roll in the machine has nearly expired, considerable slack is
unwound from the fresh roll, and then, at the proper time, the tucker blade is
struck up between the drawing-in cylinder and the tapes, thus introducing the
fresh web from the new web-roll into the machine, and pasting the new web on
to the end of the web drawn from the expiring web-roll."
A knife is arranged so that the same will move to cut off the web from the
expiring web-roll, as the fresh web is introduced in this manner.
Means are also provided so that as soon as the fresh web has been started in
in this manner, the expired web-roll or stub can be removed, and the fresh web-
roll rolled into position.
A gear is preferably secured on the shaft of the fresh web-roll, and is so
arranged that when the fresh web-roll drops into its operative position, this gear
will mesh with a gear or an adjustable braking device, so that the web-roll can
be kept under tension, as is customary.

page_text: Means are also provided so that the web-roll can be adjusted axially when the
same is in position.
Suitable catches or detents are used to keep the fresh web-roll in its operative
position.
By this arrangement, the fresh web can be quickly introduced into the machine,
and preferably only by slowing down the printing press without entirely stopping
the operation thereof.
In a modified form of this first improvement, I provide framework with inclined
tops for supporting the shafts of the web-rolls, and suitable sprocket-wheels and
chains having open boxes for engaging the web-roll shafts.
Turning with one of the sprocket-wheels is a stop-disk, and coacting with this
stop-disk is a brake-lever having an abutment for engaging suitable stops or pro-
jections on the stop-disk, to hold the desired web-roll in position to co-operate with
the feeding-in device of the press.
When the brake-lever is released or moved out of engagement with the stop-
disks, the weight of the web-rolls will cause them to roll down on the inclined
supports until one of the abutments of the stop-disk again engages with the
brake-lever.
The motion or advance of the web-rolls down their inclined support can be
accurately controlled by varying the pressure exerted on the brake-lever.
The tucker-blade in this modification is connected with and actuated from the
brake-lever.
In some instances a pasting mechanism is provided, and arranged so that the
end of the fresh web will receive a deposit of paste, as the tucker comes up into
position to introduce the fresh web into the machine.
Thus, by manipulating a single lever, an expiring web-roll can be removed,
a fresh web-roll brought into position to co-operate with the feeding-in devices
of the press, paste may be deposited upon the end of the fresh web, which will
then be properly inserted into the feeding-in device of the press, and the expiring
web severed or cut off.
The second improvement relates to an improved controlling mechanism for
controlling the tension of the web in a rotary web printing press, which will
automatically stop the supply of web in case of breakage or derangement of the
web in the machine, and, although the machine continues in operation, no fresh
web will be supplied thereto, and practically all "choke" will be prevented.
The specific means for accomplishing the purpose of regulating the supply of
the web, and stopping the supply in case of accident, consists of a pump actuated
from the web-roll, said pump serving as a controller or brake for the web-roll,
and said pump being arranged to pump an incompressible liquid as oil or water.
A valve is arranged in the eduction of the pump, and connections are arranged
so that said valve will be automatically adjusted by the tension of the incoming
web.
Thus, if the tension on the web is not enough, the valve will be slightly closed,
and hence the pump will have to work against more resistance.
If the tension is too much, the valve will be slightly opened, and hence the
resistance which the pump will have to work against will be decreased, and, by
this arrangement, the tension of the incoming web will be automatically regulated.
A looping device acting on the web connected to the said regulating valve
comprises the connecting means.
The pump is preferably used in connection with a circulating line of pipe,
that is, a line of pipe connecting the eduction to the induction of the pipe.
In this circulating line of pipe, one or more stop valves are also arranged,
and each stop-valve is provided with connections so that, if the web in the press
or the distributing apparatus should break, the stop-valve will be instantly closed,
and hence the web-roll instantly stopped, cutting off the supply of the web
from its source.

page_text: The connection to operate these stop valves consists of a looper roller bearing
on the web, and connections from the looper to the stop valves.
It is practical to instantly stop the web-roll as the same is only one part,
while it is not practical to stop the entire printing machine, and hence, by instantly
stopping the supply of web in case of accident, much damage to the machine is
usually avoided.
The pump used in this construction is preferably a rotary pump.
A by-pass with a valve is provided so that, by opening the same, the web-roll
can be turned to thread up the machine; but the valve in the by-pass is kept
closed in the normal operation.
A relief valve is provided between the eduction and induction of the pump
having a suitable adjusting spring for the purpose of preventing hammer, if one
of the stop-valves should be instantly closed, and this adjustable relief valve may
be adjusted to allow the web-roll to move a few inches, if the stop-valve is
instantly closed.
.
Also, by this means, the tension of the incoming web will be kept automatically
at a constant, and this operation will act to offset the increasing rotation of the
web-roll, due to its decreasing diameter.
If desired, a hand-valve may be arranged in the circulating system so that
the tension on the web-roll may be adjusted by hand at a point remote therefrom.
The third improvement consists in providing a rotary web printing press with
a system of air-brakes.
An air-pump is belted from the driving-shaft of the machine, and is connected
to a suitable reservoir or air-chamber.
Extending from the air-chamber is a pressure-pipe.
A pneumatic controlling device, consisting of a cylinder and piston connected
to a belt-shifter is arranged to stop the air-pump when the pressure in the air-
chamber has reached the desired point, and to throw the air-pump into operation
in case the pressure in the air tank falls.
A pneumatic belt-shifting device for the main belt of the machine, consisting
of a cylinder and piston connected to the belt-shifter for the main belt, is also
provided; and also in connection with this belt-shifter a brake is arranged
to bear on the tight pulley of the machine.
A plurality of pressure brakes, such as diaphragm brakes are arranged through-
out the printing mechanism to act upon the large cylinders thereof, such as the
printing and impression cylinders, the inking cylinders and the folding cylinders.
A pneumatic brake is also connected to act upon the shaft of the web-roll.
The pneumatic brakes and the belt-shifting device of the main driving shaft
of the machine are all connected to a pipe, which is termed the "service pipe."
The brake for the web-roll is also independently connected to the pressure pipe.
The service pipe is connected to the pressure pipe by a number of connecting
pipes.
In each of these connecting pipes is a valve, which is connected by means of a
suitable looper bearing on the web-roll, to automatically open whenever the web
is broken, so as to admit pressure from the pressure pipe into the service pipe.
In a separate pipe which connects the pressure pipe and the service pipe, a
valve is provided which may be moved to different positions by hand, so as to
admit pressure from the pressure pipe to the service pipe, or to cut the same off.
The brake provided in connection with the web-roll is arranged to be controlled
by a pneumatic device.
A looper is arranged to bear on the web between the web-roll and the drawing-in
device, and is connected to a valve, which controls the admission of pressure into
this pneumatic device connected to the web-roll brake, so that by this mechanism
the tension of the brake on the web-roll can be automatically controlled through
pneumatic means.
The entire device is so arranged that, if the web should break, or if the hand-

page_text: valve should be properly operated, pressure will be admitted from the pressure
pipe into the service pipe to immediately set the brakes throughout the entire
inachine, to check the web-roll, and to throw the main belt off, and thus to as
instantly as possible stop the machine.
The hand-valve is also arranged so that the brakes may be released, and the
belt again thrown on to start the machine in operation.
The fourth improvement relates to an improved inking mechanism for rotary
web printing machines, and especially relates to a ductor mechanism for taking
the ink from the ink-fountain.
By this invention, a ductor roller is provided, which is rotary in action, and
which is so rotated that the same will roll over the fountain roller without slippage,
and so that the same will supply ink to the distributing or receiving roller, and
will turn therewith so that there will be substantially no strain put on the
periphery of the ductor-roller.
In other words, the driving means for the ductor-roller is so arranged that the
ductor will run over the fountain-roller and turn with the receiving roller.
By making the ductor rotate, oscillation or reciprocation thereof is done away
with, and a faster running device is provided, and a device is also provided so
that a plurality of ductor-rollers can be used to take the ink from the fountain
50 that as many supplies of ink can be provided as desired for each revolution.
The specific construction used consists in mounting frames upon a rotary shaft
which carry a number of ductor rollers, and coacting with each of these ductor
rollers is a distributing roller.
A stationary, internal gear is arranged to coact with gearing carried by the
rotating frames to drive the distributing rollers, so that, as the ductor rollers and
distributing rollers rotate, the same will turn or their own axes.
The ductor rollers are mounted in arms, which are pivoted on the shaft of the
distributing rollers.
Stationary cam-disks are provided, so that the ductor rollers will be moved in
and out from the centre of rotation as they rotate.
A suitable ink fountain is provided with an ink fountain roller, which is
jogged intermittently forwards by any of the usual ratchet-and-pawl mechanisms,
and a receiving roller is also provided.
The receiving roller is set so that the rotary distributing rollers will just touch
the same.
The ductor rollers, as they rotate, are so controlled by the cam mechanisms
that they will roll over the surface of the fountain roller, but will not contact
with the receiving roller.
The distributing rollers will contact with and turn with the receiving roller
as they pass by the same, and thus supply ink to the receiving roller, and thus
to the machine.
By this means, the ductors can be kept constantly in operation, and the ductors
turning on their own axes as they rotate, will roll over the surface of the fountain
roller, which is approximately stationary, without slip; and, as the distributing
rollers also engage the receiving roller without slip, the rollers will last for a long
time, and an even supply of ink will be nicely and almost continuously supplied
to the type cylinders.
The fifth improvement consists in providing a continuously rotating cylinder
and set of tapes for pulling the web from the web-roll and passing the same into
the machine, and also consists in providing an inking apparatus in which a
number of distributing rollers, as four, are used, which gradually increase in
size, and which break joints, so that the ink will be nicely distributed, and so that
a small number of composition rollers can be used and arranged for easy access;
and also consists in providing a system of pipes, so that water can be circulated
through said distributing drums, whereby the same may be warmed before the
press is started, and cooled or kept at a uniform temperature while the press is

page_text: running, and further consists in providing a plurality of ink fountains for each
inking apparatus, so arranged that either one of the plurality of fountains can be
thrown into operation so that different qualities or colored inks may be supplied
by the same distributing apparatus.
The preferred way to circulate the water through the distributing rolls consists
in arranging a tank above the same, and a pipe line which will circulate water
through the distributing rollers, and to provide a heating device, as a system of
gas-jets in connection with this pipe system.
The sixth improvement relates to the sheet-associating and switching devices
by which after the web has been cut into sheets, the sheets are controlled and
directed in different directions so as to be colled or led in different paths, and the
especial point of this improvement consists in providing a rotary switch.
This rotary switch consists of two arms rigidly mounted on the rotary shaft, and
arranged between these two arms is a shaft, which carries a number of switch
fingers, and this shaft may be turned and secured in two positions, so that said
switch fingers will project outwardly from the shaft, or inwardly toward the
axis.
If this rotary switching device is used in connection with a collecting cylinder,
the same is so geared that the rotary switch fingers will direct every alternate
sheet up around the collecting cylinder, so that the sheets will be collected
thereon.
This rotary switch is a very desirable feature in fast-running rotary presses.
The switches that have been used before for this purpose have been cam-actuated
and they have been found in practice to rapidly and quickly wear out.
On the other hand, a mechanism which continuously rotates has no jars or
shocks imparted thereto, and does not depend on the accuracy of a cam or cams
for its nicety of operation.
By turning the switch fingers inwardly, the switch is rendered inoperative.
The arms which carry said shaft are preferably counter-weighted.
This rotary switch may be used to direct sheets into different pathways, even
if such pathways do not comprehend a collecting cylinder.
The seventh improvement relates to an improved rotary folding and delivering
mechanism for folding and delivering the sheets after they have been cut from
the web and collected or not, as desired.
The improved rotary folder consists of a rotating drum, a pair of folding rollers,
and gearing for rotating the folding rollers bodily around the rotating drum in
opposition to the peripheral movement thereof.
Extending from one of the folding rollers is a set of tapes, which bear on the
rotating drum.
Coacting with the folding rollers is a folding blade, which is rigidly mounted
on a rotary shaft, and which is adapted to tuck the sheets into the bite of the
folding rollers simply by its rotation.
Generally a plurality of sets of folding rollers and tapes are arranged in com-
bination with one rotating drum, so that a number of sheets may be folded by
said drum.
Also turning with the folding blade or blades is a part which is termed a
"controlling blade," the function of which is to control the free end of the sheet
while the same is passing into position to be tucked into the bite of the folding
rollers.
The folding rollers and their tape rollers are mounted in frames, which are
journalled on the shaft of the rotary drum, and although spur gearing is provided
so that the rollers will rotate in opposition to the movement of the folding drum.
Gearing is also provided between the folding drum and the folding rollers,
so that the folding rollers and tapes will turn in the proper directions.
The improvements above described as forming the various parts which go to

page_text: make up this invention may be used singly or combined substantially together
in one rotary printing, collecting and folding machine.

Improvements in Rotary Web Printing Machines and Collecting and
Folding Mechanisms connected therewith.
I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, London, W.C.,
Consulting Engineer (a communication from The Campbell Printing Press and
Manufacturing Company, corporation organised under the laws of the State of
New York, of 1, Madison Avenue, City, County, and State of New York,
Manufacturers), 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:-
These improvements relate to that class of machines which print upon paper
in the form of strips of indefinite length or webs by means of one or more couples
of constantly rotating printing or type cylinders and co-acting impression cylinders.
Presses of this character are termed rotary web presses" and are ordinarily
used for printing newspapers or similar products.
The conditions under which newspapers are published or printed to-day make
it essential that the printing presses employed should be capable of operating at
extremely high rates of speed.
The especial object of the present improvements is, therefore, to simplify and
facilitate the operations in rotary web printing presses and folding machines
so that the same may be run at higher speeds and produce superior products over
the forms of presses which are now employed, and to facilitate the rapid delivery
of the folded products.
The present improvements may be classified under seven heads.
The first improvement relates to means by which a fresh web-roll or spool can
be introduced into the machine without losing time.
The mechanisms preferably employed for carrying out this improvement are
illustrated in the first seven sheets of drawings.
The second improvement relates to a controlling mechanism for regulating the
tension of the web and for automatically stopping the supply of web in case of
breakage or its disarrangement in the machine.
The mechanisms preferably employed for carrying out this second improvement
are illustrated in sheets 8 to 10 inclusive of the drawings.
The third improvement consists in providing a system of fluid pressure brakes
for stopping the parts of the machine, or controlling the speed thereof.
The mechanisms preferably employed for carrying out this improvement are
illustrated in sheets 11 to 13 inclusive of the drawings.
The fourth improvement relates to novel ink-supplying devices for the press,
and the mechanisms preferably employed for carrying out this improvement are
illustrated in sheets 14 to 16 inclusive of the drawings.
The fifth improvement consists in proportioning the ink-distributing rollers
so that the ink will be more evenly divided or distributed; and further in pro-
viding a circulation of water for maintaining the inking apparatus at the best
working temperature therefor.

page_text: The mechanisms preferably employed for carrying out this fifth improvement
are illustrated in sheets 17 to 19 inclusive.
The sixth improvement relates to means for rendering the sheet-associating
and switching devices more efficient by employing a rotary switch.
The mechanisms preferably employed for carrying out this sixth improvement
are most clearly illustrated in sheets 20 to 22 inclusive.
The seventh or last improvement relates to the folding and delivering mechanisms
for folding and delivering the sheets after they have been cut from the web and
collected or not, as desired.
The mechanisms preferably employed for carrying out this seventh or last
improvement are illustrated in sheets 23 to 25 inclusive of the drawings.
These several improvements may all be combined and used in a single printing
press and folding machine, or they may be applied singly to existing forms
of printing presses, or various ones of them may be combined, and others omitted
to serve the various ends sought to be accomplished.
Referring to the first seven sheets of drawings, which illustrate mechanisms
which may be employed for providing a fresh web supply to web printing presses,
Fig. 1 is a sectional view of a web-roll illustrating the way the supporting-
shaft is applied thereto,
Fig. 2 is a diagramatic sectional view of the parts of a printing machine with
a web-roll supplying device applied thereto,
Fig. 3 is a perspective view of a part which is termed the "tucker,"
Fig. 4 is a detail view of the shearing-knife,
Fig. 5 is a partial end elevation showing the mounting of the web-roll,
Fig. 5 is a detail view of the device for adjusting the web-roll longitudinally,
Fig. 6 is a partial side view of the web-supplying devices,
Figs. 7 to 10 inclusive are diagramatic views illustrating the operation of the
parts,
Fig. 11 is a side view partially in section illustrating a modified form of web-
supplying apparatus, which constitutes means for automatically bringing a
fresh web-roll into position, and automatically applying paste to the end of the
fresh web,
Fig. 12 is a detail sectional view thereof,
Fig. 13 is a detail view illustrating a pawl forming part of the operating
mechanism,
Fig. 14 is a transverse, detail, sectional view,
Figs. 15 to 17 inclusive are diagramatic views illustrating the operation of
a modified form of web-roll supplying devices, and
Fig. 18 is a side view illustrating a further modified form of mechanism for
furnishing a fresh web-supply to a printing press.
In the operation of web printing presses now employed in printing newspapers,
much time is wasted in supplying the machine with fresh web-rolls to take the
place of a roll from which the web has been withdrawn.
When the web-roll of existing printing machines has expired, the machine is
now stopped, the web cut by hand from the expired web-roll or
stub" as it is
sometimes called, and a fresh web-roll is placed by hand in position, and the end
of the web drawn therefrom by hand, and pasted by hand to the end of the
web previously used.
The machine is then slowly started in operation to draw the end of the fresh
web through the machine.
These operations necessarily require time, and decrease the output of the press.
The especial aim of the present improvements is to provide means whereby the
end of the fresh web can be attached to the web in the machine, the parts being
preferably arranged so that this operation can take place without stopping the press.
Referring in detail to the construction illustrated in the first three sheets of
drawings, 11, 12, 13 and 14 designate the cylinders of a rotary printing machine,
and 15 designates a roller or guide for directing the web thereto.

page_text: D designates a drawing-in device for unwinding the web from the roll, which
drawing-in device consists of a drum 16, rollers 17 and 18, and tapes 20, the
tension of which can be regulated by an adjustable roller 19.
A rock-shaft 21 is journalled in the side-frames 29.
Secured upon the rock-shaft 21 are arms 22 carrying a tucker-blade 23 prefer-
ably having small projections 24 on the upper edge thereof.
Also secured on the rock-shaft 21 is a handle 21º.
These parts are so arranged that, when the handle 21° is depressed, the tucker-
blade 23 will be forced up into the bite between the drum 16 and roller 17.
Also journalled in the frames is a rock-shaft 25 carrying a blade 26 having
serrations or teeth 26º.
A spring 20¹ normally holds the blade 26 away from the web, as shown in
Fig. 6.
Projecting from the shaft 25 is an arm 27 arranged in position to be struck
by the tucker-blade 23, as the same is moved upwardly, so as to turn the knife 26
into engagement with the web w.
30 designates a web-roll shaft carrying a centering cone and gear 31.
Fitting on to the opposite end of the shaft is a cone 33, which may be made
with inter-locking sections in the usual way, which may be fastened by a nut 34.
The web-roll shaft 30 is inserted from the right-hand end of the web-roll,
as shown in Fig. 1, the cone-sections applied thereto, and the nut 34 tightened
up on the cone-sections so that the web-roll will be accurately centered and secured
on the shaft 30.
35 designates a runway or guides projecting from the frame to facilitate the
introduction of the web-roll shaft 30 into the notches 36.
From the notches 36, the frames incline downwardly, as at 37, to form tracks,
so that, if the shaft of the web-roll is raised out of the notches 36, the same will
run down the tracks and drop in the notches 38 forming bearings for the web-
roll shaft, when in operative position.
Journalled on studs 40 are latches 39 normally held by springs 41 to secure the
web-roll shaft in the notches 38.
Extending across the frames is a rock-shaft 43 having handles 44 secured on
its opposite ends, which handles 44 are connected to release the latches 39 by
links 42.
The mechanism for tensioning the web-roll and for adjusting the same longi-
tudinally includes a gear 45 having guiding flanges 46 on the side thereof, which
gear is mounted on a shaft 47 carrying a brake-disk 48.
Brake-shoes 49 are hung on a bracket 54, the ends of which are tapped into
the side-frame and into a bracket 57 projecting therefrom.
By turning a hand-wheel 55, the tensioning mechanism can be adjusted axially
to bring the web-roll into proper alignment.
The brake-shoes 49 may be adjusted to give the desired resistance or tension
to the web-roll by means of a shaft 50 journalled in bearings 52 and carrying a
hand-wheel 51.
In operating a printing press provided with web-supplying devices of the
construction described, the end of the fresh web is secured on the tucker-blade 23,
as illustrated in Fig. 7, and, if desired, paste may be applied thereto by hand.
By operating the handle 21°, the end of the fresh web will be tucked into the
bite between the rollers 16 and 17, and the expiring web will be severed, as
illustrated in Fig. 8, so that a fresh supply of web may be introduced into the
press without stopping its operation, as illustrated in Fig. 9.
The stub or old web-roll may then be removed from the machine and the fresh
web-roll pushed down the inclined tracks to its normal operative position, as
shown in Fig. 10.
In some instances, instead of starting the fresh web-roll down the inclined
tracks by hand, it may be desirable to provide a construction for automatically

page_text: bringing the fresh web-roll into its operative position, and a construction designed
to operate in this manner is illustrated on sheets 4 to 7 inclusive.
Referring to these sheets and in detail, Fig. 11 is a side view partially in section
illustrating a first modified form of web-roll supplying device including mechanism
for automatically applying paste to the end of the fresh web.
A designates the side-frames. B designates a web-roll supporting-frame.
W, WI and W2 designate web-rolls secured upon shafts 13, which rest upon
inclined tracks formed by the frame-work B.
Secured upon the shafts 13 are gears 14 for engaging tension-adjusting devices
comprising a flanged gear 20 secured on a shaft 21, which has a brake-disk 22,
said shaft 21 being longitudinally adjustable by means of a hand-wheel 23, and
the tension of the brake-disks being capable of adjustment by a shaft 24 carrying
a hand-wheel 25, this mechanism for tensioning and aligning the web-roll being
of substantially the same construction as described with respect to the previous
modification.
Mounted in the, frame-work B are sprocket-wheels 15 carrying sprocket-
chains 16, which carry boxes 17 which run on ledges 17º, as shown in Fig. 14.
Turning with one of the sprocket-wheels 15 is a stop-disk 18 having pro-
jections 18°.
A brake-lever 19 is journalled in the frame-work B, and provided with a catch
or abutment 190 for engaging the projections of the stop-disk 18.
By means of this construction, when the brake-lever 19 is raised out of engage-
ment with the stop-disk 18, the web-rolls will move down their inclined support
through the influence of gravity, until the brake-lever 19 is again brought into
engagement with the stop-disk 18.
The transfer or motion of web-rolls in this manner can be governed by varying
the pressure on the brake-lever 19.
A link 26 connects the brake-lever 19 with an arm 27 extending from a rock-
shaft 28 journalled in the frames A.
Secured upon the rock-shaft 28 outside the frame-work A are arms 29 extending
down from which are arms 30 carrying a pasting-roller 31, which co-operates with
a paste-fountain 32.
The shaft of the pasting-roller 31 extends through slots or guides 33 in the
frame-work A, so that the pasting-roller will be guided in a curved path to
deposit paste upon the end of a fresh web secured upon the tucker-blade 34.
The tucker-blade 34 is carried by curved arms extending from a rock-shaft 36.
A latch 41 is arranged to hold the tucker-blade 34 down in its normal position
against the tension of a spring 37.
A pawl 40 is journalled upon one of the arms 30, as shown in Fig. 13.
To restore the tucker-blade to its normal position after the same has been
operated by its spring to tuck the end of the fresh web into the feeding-in device
is a slotted link 38 extending down from one of the arms 39 to engage a pin carried
by an arm 39 on the rock-shaft 36.
A pivoted web-severing knife 43 normally held away from the web by a spring 44
is located in position to be actuated by the tucker-blade when the same is operated
to tuck in the end of the fresh web.
As illustrated diagrammatically in Figs. 15 to 17, by the manipulation of the
single brake-lever 19, an expiring web-roll can be moved from position, a fresh
web-roll brought into position to co-operate with the feeding-in devices of the
press, the end of the fresh web pasted and properly inserted into the feeding-in
device, and the expiring web automatically severed or cut off.
A web-roll supplying device of this character may by simplified by omitting the
pasting-roller and fountain, and a modified construction of this character is illus-
trated in Fig. 18.
Referring to said figure, A designates one of the side-frames.
Mounted in the side-frames A is a feeding-in device comprising the drum 10,
tape-rollers 12 and feeding-tapes 11.

page_text: Instead of employing a separate frame-work to support the web-rolls, the side-
frames A may be extended, as at A¹, the upper surfaces of the extensions A¹
being inclined to form a track for the shafts 13 of the web-rolls.
Journalled in the extensions A¹ of the side-frames A are sprocket-wheels 50
carrying chains 51, which chains 51 are provided with boxes 52.
Secured upon one of the sprocket-wheel shafts is a stop disk 53, co-operating with
which is a brake-lever 54.
A link 55 connects the brake-lever directly with a tucker 56.
A web-severing device or knife 57 is located in position to be operated by the
tucker 56, and is normally held back out of the way of the web by a spring 58.
By raising the brake-lever 54, the web-rolls will be released so as to roll down
their inclined support to remove the expiring web-roll, and bring a fresh web-
roll automatically into position, while, at the same time, the end of the fresh
web will be introduced into the feeding-in device, and the expiring web will be
severed or cut off.
Obviously these mechanisms for automatically supplying a fresh web supply
to a printing press may be further modified or changed, and it is not intended that
this specification should be limited to the specific forms of devices illustrated for
carrying out this first improvement.
Referring to sheets 8 to 10 inclusive of the drawings which illustrate automatic
web-tensioning and stopping devices for web printing presses,
Fig. 19 is a side view of a web press with this improvement applied thereto,
Figs. 20 and 21 are detail sectional views of two of the valves,
Fig. 22 is a diagrammatic sectional view of the press,
Fig. 23 is an enlarged section view of the pump, and
Fig. 24 is an enlarged detail view illustrating the connections for operating the
pump from the web-roll.
The specific mechanism herein illustrated for carrying out this second improve-
ment consists of a pump for circulating water, oil or other compressible liquid.
The action of the pump is regulated by valves, 'so that, if the tension of the
web is not sufficient, the valve or valves may be more or less closed or throttled to
increase the resistance of the pump.
Referring to the drawings and in detail, A designates the framing; B, C, D
and E, the printing and impression cylinders; F, the inking apparatus; G, the
folding or delivery mechanism; and W, the web-roll from which the web w may
be drawn.
The web is led over a roll 10, through a feeding-in device comprising the
drum 11, rollers 13, 14 and 15, and tapes 12.
From the printing cylinders the web passes around rollers 17, 18, 19 and 20
to the folding apparatus.
The web-roll shaft 21 is slabbed, as at 22, and provided with a coupling 23
secured in place by a pin 23º, as shown in Fig. 24.
P designates a suitable pump, preferably a rotary pump.
The shaft 24 of the pump is slabbed, as at 25 to engage the slabbed end of the
web-roll shaft, as shown in Fig. 24.
The pump illustrated comprises a casing, mounted in which are two inter-
meshing gears 26 and 27.
An induction pipe 28 connects to one compartment of the pump, and an induc-
tion pipe 29 to the other compartment of the pump.
These two pipes are connected together, and form a circulating system for
the liquid.
A valve 30, which may be operated by a handle 31, is arranged in the pump-
casing.
By opening this valve, the two compartments of the pump may be connected
so that the pump will offer practically no resistance to the operation of the
web-roll.
During the normal operation of the machine, this valve is kept shut.

page_text: A shunt pipe 32 may be arranged to connect the pipes 28 and 29, and may be
provided with a relier-valve closing towards the pipe 28.
This relief valve is intended to prevent water-hammering from breaking the
parts when the circulation of liquid is stopped suddenly.
Bearing on the web between the roller 10 and drawing-in cylinder 11 is a roller 35
mounted in arms 36, which are secured to a shaft 37.
On the end of the shaft 37 is an arm 38, which is connected by a link 39
to the lever 40 of a valve 41.
A spring 42, the tension of which may be adjusted by a screw 43 and nut 43°
normally tends to hold the roller 35 into contact with the web with a certain
degree of pressure.
This mechanism acts to keep a constant tension on the incoming web; for
instance, if the tension on the web becomes slack, the roller 35 will be pulled up
by the spring to throttle or close the valve 41 to a greater or less extent.
If the tension of the web becomes too great, the roller 35 will be forced down,
and the valve 41 opened wide.
This will vary the pressure the pump has to work against, and hence will
offer a greater or less resistance to the unwinding of the web from the roll.
Bearing on the web between the drawing-in cylinder 11 and first impression
cylinder is a roller 44, mounted in arms 45 secured on a shaft 46.
Secured on the end of the shaft 46 is a lever 47, which is connected by a link 48
to a bell-crank lever 49 mounted on a valve-stem 52.
A weight 53 is adjustably mounted on the other arm of the bell-crank lever.
If the web should break between the drawing-in cylinder and first impression
cylinder, the weight 53 would fall instantly, closing the valve 32, thus stopping
the pump, and holding the web-roll from turning, so that the supply of web will
be instantly cut off.
If desired, a plurality of stopping devices may be employed, and, as illustrated,
54 is a roller bearing on the web between rollers 19 and 20, or just before the web
passes to the delivery apparatus.
The roller 54 is journalled in arms 55 secured upon a shaft 56, which carries
a lever 57 connected by a link 58 to a bell-crank lever 59, which is carried by
the valve-stem, and has an adjustable weight 63 arranged substantially as before
described.
04 designates a throttle-valve, which may be controlled by a lever 65, and,
as this throttle-valve 64 is located near the delivery end of the press, at or about
the place usually occupied by the operator, this throttle-valve forms a convenient
instrumentality whereby the operator may control the tension of the web by
throttling or closing the valve 64 to the desired extent.
It is obvious, of course, that the details of this apparatus for controlling the
tension of the web-supply, and stopping the same when desired, can be applied
to different forms of presses, and that the details of the same can be widely
modified..
When rotary printing machines are being driven at high rates of speed, the
printing cylinders and other moving parts acquire such heavy momentum that
it is impossible to arrest their motion suddenly, without straining the press and
placing undue wear on the frame-work and bearings thereof.
The third improvement is designed to overcome this difficulty in rotary printing
machines by providing a system of fluid pressure-brakes.
Referring to sheets 11 to 13 illustrating this improvement as applied to a
web press,
Fig. 25 is a diagrammatic side view of a press provided with controlling devices
constructed according to this improvement,
Fig. 26 is a partial plan view of the press,
Fig. 27 is a detail view illustrating a belt-shifting device and brake,
Fig. 28 to 31 are detail sectional views illustrating different positions of the
controlling valve, and

page_text: Fig. 32 is a partial side view showing the opposite side of the press from that
illustrated in Fig. 25.
Referring to the drawings and in detail, F designates the framing journalled at
one end of which is a web-roll W.
15, 16, 17 and 18 designate the printing and impression cylinders of the
press.
25 and 26 designate the ink-drums.
From the roll W, the web w passes under a roller 10, around a drawing-in
device comprising a drum 13 and sets of tapes 12 and 14, through the printing
couples of the press, under rollers 19 and 21, between the rollers 22 and 23 to the
folding apparatus, which folding apparatus is represented as provided with one
or more sets of drawing-rolls as 24.
The driving-shaft 27 (see Fig. 26) is provided with a loose pulley 29 and tight
pulley 30.
28 designates the main driving gear.
On the end of the driving-shaft 21 is secured a pulley 32 belted by a belt 33
to actuate an air-pump.
Carried on the pump-shaft 36 is a loose pulley 35 and a tight pulley 34.
At its opposite end, the pump-shaft 36 carries a crank-disk 37 connected to
operate the piston of an air-pump 38 in the ordinary manner.
31 designates an air-receiver or reservoir.
The air-chamber 31 is connected by a pipe 39 to a cylinder 40.
When the pressure in the air-chamber 31 has reached the desired height, the
spring-pressed plunger 400 mounted in the cylinder 41 will be forced out so as
to shift the belt 33 on to the loose pulley 35, thus stopping the action of the
air-pump.
Leading from the air-chamber 31 is a pipe 42, which extends around to the
opposite side of the press, and constitutes what may be termed the pressure
pipe.
Fastened on the web-roll shaft is a disk 43 (See Fig. 25).
Engaging the disk 43 are brake-shoes 44 and 45 connected to be operated by
toggle-links 46 and 47 from a diaphragm mounted in a casing 48.
The diaphragm casing 48 is connected by a pipe 49 to the pressure-pipe 42.
Bearing on the web between the roller 10 and the drawing-in device is a
roller 54 journalled in spring-pressed arms 5:30, which are connected by a link 52
to the arm 51 of the throttle-valve 50.
When the tension on the web is too light, the roller 54 will rise, the throttle-
valve 50 will be opened to admit pressure, operating the brake-shoes 44 and 45
to increase the tension upon the web-roll.
Extending alongside the press parallel with the pressure-pipe 42 is a pipe 52,
which may be termed the service pipe."
"
The service-pipe 52 has branches 53, 54, 55, 56, 57, 58, 58° and 59.
The branch 53 has an inwardly opening check-valve- 54°, and is connected at
its end with the pipe 41 before referred to.
The branch 54 leads to a diaphragm chamber 60, controlling a brake-shoe 61
for the ink-drum 25.
The branch 55, through the diaphragm casing 62, controls a brake-shoe 63
of the first printing cylinder.
The branch 56 controls a brake-shoe 65 through a diaphragm casing 64 for
the first impression cylinder.
The branch 57, through a diaphragm chamber 66, controls a brake-shoe 67 for
the second impression cylinder.
The branch 58, through a diaphragm casing 68 controls a brake-shoe 69 for
the second printing cylinder; and the branch 58%, through a diaphragm casing
70, controls a brake-shoe 71 for the second inking-drum.

page_text: The branch 59, through a spring-pressed plunger in the cylinder 72 controls
a brake-shoe 73 for the drawing-in roller 74 of the folding apparatus.
The branches 53 to 59 inclusive are provided with cut-off valves, which may be
operated to render one or more of these brakes inoperative.
The pressure-pipe is provided with a branch 83 leading to a main controlling
valve 84 extending down from which is a pipe 85 connected to the service
pipe 52.
Leading ordinarily from the controlling valve 84 and pipe-85 respectively
are pipes 86 and 88 connected to the opposite ends of a controlling cylinder, as
illustrated in Fig. 27.
The cylinder 87 is provided with a plunger 89 having a piston-rod 89 carry-
ing a belt-shifter 91, and connected by links 92 and 93 to a rock-shaft 94 having
an eccentric 95 controlling the brake-shoe 96, which co-operates with the main
driving pulley 30.
As illustrated by the diagrams (Figs. 28 to 31 inclusive), the controlling
valve 84 can be set to simultaneously apply the brakes, or to shift the driving-
belt, as desired.
By closing a shut-off valve 86° in the pipe 85, as shown in Fig. 25, the con-
trolling-valve 84 may be cut off from the service-pipe, and used for controlling
the belt-shifter alone.
Bearing up on the web near the drawing-in device, as shown in Fig. 25, is
a roller 80%, journalled in arms 79 connected by a link to a detent 76 for holding
a valve 75, which connects the pressure-pipe 42 and service-pipe 52 in a normally
closed position.
The roller 800 is narrow enough to pass between the tapes 12, but will be held
from doing so by the web w.
On a failure or breaking of the web w, the connections from the roller 80°
will act automatically to admit pressure to the service-pipe 52 simultaneously
applying the brakes to the various parts of the machine to bring the same promptly
to rest.
Resting on the web between the rollers 20 and 21 is a roller 82, which controls
a valve 81 in the pipe 80, connecting the end of the pressure-pipe 42 with the
service-pipe 52.
If the web should break near the delivery end of the press, the roller 82 would
bo left free to fall, and the brakes would be automatically applied to bring the
machine to rest.
The mechanical details whereby fluid pressure-brakes are applied to stop or
regulate the speed of the parts of the printing press can, of course, be widely
varied, and the brakes may either be controlled automatically or by hand, as
desired, by many different forms of valves.
In the ordinary forms of inking apparatus, the ductor-roller which conveys
ink from the fountain to the ink-distributing rollers is either reciprocated or
oscillated, and the hammering caused by the contact of the ductor-roller with
the fountain and distributor-rollers causes these parts to wear quickly, so that
they have to be frequently replaced.
The fourth improvement, which relates to the inking apparatus, is designed to
overcome this difficulty by providing a novel ductor-mechanism, in which one or
more ductor-rollers are caused to advance or revolve in an orbit
Referring to sheets 14 to 16 inclusive, which illustrate this improvement,
Fig. 33 is a diagrammatic, sectional view of an inking apparatus constructed
according to the present invention,
Fig. 34 is an illustrative diagram to be referred to,
Fig. 35 is a sectional view taken on the line 2-2 of Fig. 37,
Fig. 36 is a similar view showing the parts in a different relative position,
and
Fig. 37 is a sectional view taken on the line 44 of Fig. 33.
Referring to Figs. 33 to 36. which illustrate the preferred form of inhi

page_text: apparatus employed for carrying out this improvement, A and B designate the
side-frames; C, the impression cylinder; D, the printing cylinder; E, an ink-
drum and F and F, form rollers.
These parts may be of the usual construction employed in rotary web presses.
G designates a composition-roller bearing on the ink-drum E; H, a metallic
roller on which the composition-roller bears; M, a composition-roller; and I,
an ink-fountain.
The fountain-roller J is turned slowly by any of the usual ratchet mechanisms,
as K, not necessary to describe at length, so that the ink will be taken up from
the fountain to the surface of the roller J.
10 designates a shaft mounted in bearings 11 in the frames A and B, which has
a gear or pinion 12 on the end thereof, by which the same is simultaneously
rotated.
Mounted on this shaft 10 are arms or plates 13 (See Fig. 37), journalled in which
are metallic receiving-rollers 14 and 14°.
On the shafts of the receiving-rollers are arms 15 and 150 carrying ductors 16
and 160.
Journalled on the arms 15 and 15° are rollers 17 and 17°, which fit into
grooved-plates 18 and 18°.
The receiving-roller 14 is provided with a gear 20, and the receiving-roller 14°
has a gear 20º.
A driving-gear 22 meshes with the gear 20, and a driving-pinion 220 meshes
with. the gear 20º.
The driving-gears 22 and 220 mesh into and are driven from an internal gear
or rack 23.
The operation of this inking apparatus is as follows:-
The parts are so proportioned that the receiving-rollers do not touch the fountain-
roller J, but would engage with the composition-roller M.
The ductor-rollers 16 and 160 are moved in and out by means of the grooves
referred to, so as to engage the fountain-roller J, and clear the composition-
roller M.
The gearing is so proportioned that the resultant surface speed of the receiving-
rollers will be substantially the same as the peripheral speed of the composition-
roller M, so that there will be no impact or slippage to wear the composition-roller M.
By means of this construction, a rapid and accurate transfer of ink takes place,
and a device is provided in which the composition-rollers will not be speedily
worn or battered out of shape.
A modified form of construction is illustrated diagrammatically in Fig. 34.
Referring to this Figure, I designates a fountain.
J designates the fountain-roller thereof.
16 designates a ductor, and 14, a receiving-drum.
The ductor-roller 16 is journalled on rings 25, which may be turned or rotated,
and in this modification, it will be seen that the ductor-roller may be revolved
in a curved orbit, and, as the fountain is inside the orbit and the distributing
roller outside of the same, the gearing for driving the parts may be so proportioned
that there will not be any slippage or wear between the ductor and these parts.
The fifth improvement is designed to secure a better distribution of the ink
to facilitate printing with the different inks, and to provide a circulation of
water for maintaining the ink-supply at constant temperature, and is illustrated
in sheets 17 to 19 inclusive, referring to which,
Fig. 38 is a side elevation of a printing machine containing this improve-
ment,
Fig. 39 is a sectional diagrammatic view thereof.
Figs. 40 and 41 are enlarged detail views of the connections for driving the
fountain-roller, and
Fig. 42 illustrates a slightly modified arrangement of the ink-fountains.
Referring to the drawings and in detail, A designates the framing; B, the

page_text: first printing cylinder; C, the first impression cylinder; D, the second impression
cylinder; and E, the second printing cylinder.
These parts are geared in the ordinary manner to print a web w, which is
drawn from a web-roll W.
From the web-roll W, the web w passes through a drawing device comprising
a drum 10 and rollers 12, 13 and 14 carrying tapes 11.
From the printing mechanism, the web is led around rollers 17, 18 and 19 to
suitable folding mechanism, as F.
Referring to the inking mechanism, G and G¹ represent fountains having
fountain-rollers 20.
These fountains are carried on a suitable plate or base 21, fitted to slide in
ways 22 in the framing of the machine.
A shaft 23, journalled in the frames under the plate 21, carries pinions 24,
which mesh with racks 25 secured to said plate.
The end of the shaft 23 may be provided with a square head, and a handle 26
may be fitted thereon.
By shifting the plate 21, either ink-fountain may be brought into operative
position.
The shafts 27 of the fountain-rollers 20 project through the sides of the fountain-
casing, as shown in Fig. 41.
A hollow shaft 28 is journalled in the frame, as shown, and carried by the
shaft 28 is a ratchet-wheel 29.
Journalled on the shaft 28 is a lever 30 carrying a spring-pressed pawl 31
engaging the ratchet-wheel 29.
The lever 30 is vibrated by a link or connection 32, which may be operated
from any desired part of the machine.
The lever 30 is slotted so that the connecting link 32 may be set to rotate the
ratchet-wheel more or less, as desired.
Movable longitudinally in the hollow shaft 28 is a spring-pressed rod having
a handle or knob 36 at one end, and a square section 39 at the opposite end.
By this construction, by pulling out the knob 36 and moving the desired
fountain into position, different colored inks may be supplied to the press, as
desired.
A modified construction for using ink-fountains interchangeably is illustrated
in Fig. 42.
In this modification, the two ink-fountains G and G₁ are secured rigidly in the
framing.
Bell-crank levers 42 are journalled in the framing so that the ductor-roller 4]º
can be carried by either arms of the bell-cranks.
Referring to Figs. 38 and 39, 42, 43 and 44 designate distributing rollers or
drums.
Bearing on the distributing rallers 41 and 42 is a composition-roller 45, and
bearing on the distributing drums 42 and 43 is a composition-roller 46, and bearing
on the distributing-drums 43 and 44 is a composition-roller 47, and bearing on
the distributing-drums 44 and the printing cylinders are composition or form-
rollers 48 and 49.
The composition-rollers 45, 46, 47 and 48 are journalled in bearings in the side-
frame, and, as the same rests on top of the distributing-rollers, they may be readily
placed in position or removed.
It will be noted that the distributing-rollers 41, 42 and 43 are of different
diameters, preferably the successive rollers increasing in diameter: that is, for
example, the diameter of the distributing-roller 41 may be five inches, the dis-
tributing roller 42 six inches, the distributing-roller 43 seven inches, and the dis-
tributing roller 48 eight inches.
Where these dimensions are adopted a more perfect distribution of ink is
secured.
In other words, as the surfaces of the cylinders do not register or mesh during

page_text: their operation, the ink is more efficiently broken up than it would be if the
cylinders were of uniform diameter, as is usually the practice.
Many press-rooms where printing presses are used are heated only during the
day-time, and are allowed to become cold at night, and, on this account, and on
account of the increased temperature of the parts due to the high rate of speed
when the press is in operation, it frequently happens that the ink will not be
sufficiently liquid, or will be too hard when the press is first started in operation,
and the temperature of the running parts may subsequently become so high as
to injure the composition-rollers.
To maintain a constant temperature, a circulation of water may be maintained,
and, as illustrated, 50 designates a water-tank, having a water-supply 51 con-
trolled by a ball-cock 52.
Leading down from the tank 50 is a pipe 53 connected by branches 54 to the
distributing devices.
The water is first carried through one journal of the distributing-roller 40,
then through the distributing-roller 43, through the distributing-roller 42, through
the distributing-roller 41, and thence, by a pipe 58, may be allowed to run off
or waste, or may be pumped back or restored to the tank 50 in any of the ordinary
manners.
A heating apparatus, as a gas-pipe 60, provided with jets 61, may be arranged
in connection with the pipe-line, as shown in Fig. 39.
When a press provided with this improvement is started in operation, the
heating-device will be employed to bring the inking-apparatus to the desired
temperature, and, after the press has been operated a short time, the gas-flame
may be turned out, and the proper amount of cool water circulated through each
distributing-roller to overcome the heat generated by the friction of the rapidly
moving parts.
The sixth improvement relates to a rotary switch for directing the sheets in
the desired direction, and is illustrated in sheets 20 to 22 inclusive of the drawings,
in which,
Fig. 43 is a side elevation of a folding machine or sheet-delivering apparatus
embodying this improvement,
Fig. 44 is a sectional view of the same,
Fig. 44 is a detail view of the switch,
Fig. 45 is a partial end view of the mechanism, and
Figs. 46 to 48 are diagrammatic views illustrating the operation.
Referring to the drawings and in detail, A designates the framing; B, a former
over which the web or webs may be folded; 10 and 11, the folding-rollers at
the nose of the former; 12 and 13, drawing-rollers; a, the forwarding tapes;
14 and 15, cutting cylinder; and 16º, guide-fingers for directing the web through
the cutting cylinders.
From the cutting cylinders, the severed sheets will pass down between tapes B
and guides 18 to a collecting cylinder 20.
The tapes B are led around tape-rollers 16, 25 and 26 so as to bear upon a part
of the periphery of the collecting cylinder 20.
Also passing around the cylinder 20 are tapes c, which pass around tape-
rollers 21 and 22.
Guides 24 are shaped at their ends 24° to form the entrance or meeting-point
of two pathways, one pathway passing up around the collecting cylinder, and
the other pathway being formed between the guides 24 and tapes B.
The sheets from the collecting cylinder will normally pass into the pathway
between the tapes B and guides 24, and, to direct the sheets into the other
pathway, I employ my improved switching mechanism, which may be called a
rotary switch, as S.
The sheets, as they pass from the collecting cylinder, will run out on tapes B,
over guides 26° to a stop 27.

page_text: When the sheets reach the stop 27, the rotary tucker or folder F, of usual
pattern, will tuck or fold the sheets into the bite of the folding rollers 28 and 29,
and, from these rollers, folded sheets will be conducted by means of tapes a
and b.
As the folded sheets run out from between the rollers 32 and 33, they will
be laid upon the delivery tapes 43.
The rotary switch, which is the feature of especial novelty of this sixth
improvement, consists of a shaft 50 mounted in the framing, and carrying arms 51,
counter-weighted as at 52.
Journalled in the arms 52 is a shaft 54 canying curved guides or switch-
fingers 55, which will intermesh with the projecting ends 240 of the guide 24.
The shaft 54 has a crank or bracket 56 carrying a screw 57, whereby, by
removing the screw and turning the arm, the switch-fingers can be turned down
towards the shaft 50, or into an inoperative position, as shown in Fig. 45.
The operation of the rotary-switch is most clearly illustrated in the diagram-
atic views (Fig. 46 to 48 inclusive).
If the switch is geared to make one turn for every two turns of the collecting-
cylinder 20, it will be seen that the sheets will normally pass from the collecting
cylinder out on the tapes b, but every alternate sheet will be taken by the
fingers 55 of the rotary switch, and its leading end raised to come into the bite
of the tapes C on the collecting cylinder 20.
This will cause every alternate sheet to pass around the collecting cylinder to
be associated with the next succeeding sheet.
By rendering the rotary-switch inoperative, as before described, sheets can pass
from the cutting cylinder direct to the folder, and thus either a single or
associated product can be delivered.
The gearing for driving the parts comprises a power-shaft 50 having a
pinion 502 driving a gear 500 secured on shaft 50 of the rotary switch.
The gear 50° drives a gear 200 on the collecting cylinder shaft, and the gear
20%, through an intermediate 20', drives the gear 15° and 14° of the cutting
cylinders.
The gear 140, through an intermediate 142, drives the gears 120 and 130 of the
drawing cylinders.
The gear 120, through the intermediates 350 and 35' drives the tape-roller
gear 320
The gear 50 of the tucker-shaft may be driven from the gear 50° through an
intermediate 50%
The seventh improvement relating to a rotary folding mechanism is illustrated
in Sheets 23 to 25 inclusive of the drawings, referring to which,
Fig. 49 is a side view of a folding and delivering mechanism comprising a
rotary folding mechanism constructed according to this improvement.
Fig. 50 is a sectional view of the same,
Fig. 51 is a detail, sectional view of the rotary folding mechanism,
Fig. 52 is a detail view of the controlling-blade, and
Figs. 53 to 56 are detail diagramatic views illustrating the operation of the
device.
Referring to the drawings and in detail, A designates the framing.
F designates the former over which the web or webs may be led down and
folded, and over which the web or webs are drawn by folding-rollers 10
and 11 and drawing-rollers 12 and 13.
From the drawing-rollers, the folded web is directed by a guide 14 into the bite
of the cutting-cylinders 15 and 16, to sever the web into sheets.
The sheets from the cutting cylinders pass on to tapes 17, and are directed by
the tapes and guides 18 to a rotary collecting-cylinder 19.
Running around the collecting-cylinder 19 are tapes 20, which pass around
tape-pulleys 21, 22 and 23,

page_text: Co-operating with the collecting-cylinder is a rotary-switch consisting of counter-
weighted arms 24 having fingers 25 mounted on a shaft 26.
Secured on the shaft 26 is a lever 260, and threaded into the lever 26° is
a screw 27.
This rotary-switch operates substantially as herein before described.
From the collecting-cylinder, the sheets pass up on tapes 17 to the roller 29,
and between the same and a roller 30, then around a roller 31, coming out between
the roller 31 and a roller 33.
Journalled in the framing is a shaft 40 carrying arms 41 having controlling-
blades 42 and tucker-blades 43.
44 designates a shaft journalled in the side-frames and carrying the rotary
folding mechanism.
Keyed on the shaft 44 is a drum 45, and loosely journalled on said shaft 44
are plates 46 having gears 47.
The drum 45 is provided at its ends with gears as 48 and 48°
Folding-rollers as 49 and 50 are journalled in the plates 46.
Pinions 51 and 51° on the shafts of the folding-rollers mesh with the gear 48
and 48° of the drum 45.
55 designates a set of delivery-tapes.
59 designates a stop against which the sheets are delivered from the folding-
mechanism.
The gearing for driving the parts, arranged as illustrated in Fig. 49, com-
prises a driving-pinion 56°, which drives the gear 58º of the rotary-switch through
an intermediate 57º.
The gear 580 drives the collecting-cylinder gear 59°, which gear 59°, through
an intermediate 60, drives the gears 61 and 62 of the drawing-rollers.
The cutting-cylinder gears 63 and 64 are also driven from this intermediate.
The gear 66 secured upon the shaft 40 is driven from the gear 580 through an
intermediato 65.
The gears 71 of the rotary folding mechanism are driven from the shaft 40
by gears 68.
The shaft 44 of the rotary folding mechanism may be driven from an inter-
mediate gear 70.
The gearing of these parts, as illustrated, may be proportioned so that, for
every half revolution of the shaft 40, the plates 46 will make one-third of a
revolution, and, as there are two tucker-plates secured on the shaft 40, and three
sets of folding-rollers journalled in the plate 46, this gearing will cause a folding-
blade to mesh into each set of folding-rollers, as the various parts are rotated.
As the sets of folding rollers are revolved around the rotating-drum 45, the
rollers will be driven by this mechanism at a comparatively higher rate of speed
than that at which the rollers are rotated around the drum, and, by this means,
a sheet tucked into the bite of one set of folding-rollers will be carried by the
rotating drums and the tapes so as to be delivered, but, as this run of the folded
sheet takes place, the folding-rollers will be moved forward so that the point of
delivery of the sheet will bring the sheets against the stop 51, so that the sheets
will rest on the tapes 55.
This delivery will take place at a comparatively slow speed, as the rollers will
then be moving in opposition to the movement by which the folded sheet passes
on to the tapes 55.
While the improvements described have been classified under seven distinct
heads, it is obvious that they all may be employed in a single, combined printing
and folding machine.
For example, the web can be automatically supplied to the press in accordance
with the first improvement; the tension of the web-roll and of the web through-
out the press can he controlled in accordance with the second improvement; the
speed of the parts of the rotary press and the stopping of the same can be con-

page_text: trolled by a system of fluid-pressure brakes in accordance with the third improve-
ment; the ink can be transferred from the fountain-rollers to the distributer-
rollers by rotary-ductors; in accordance with the fourth improvement; an inter-
changeable ink-supply and means for keeping the inking apparatus at the working
temperature which will produce the best results may be provided according to
the fifth improvement; the printed sheets may be associated together or directed
into different pathways by means of a rotary-switch according to the sixth
means of a
improvement; and the printed sheets may be folded by
rotary folding-apparatus, according to seventh improvement; and,
while it has been deemed advisable to describe each of these improvements
separately, it is to be understood that they are capable of conjoint or separate
use as desired.
