Improvements relating to Printing Machinery.
I, HENRY EDWARD NEWTON of the Office for Patents 6 Breams Buildings,
Chancery Lane in the County of Middlesex, Patent Agent, 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 :-
This invention relates to improvements in web printing machines, especially of
the class capacitated to print and deliver products varying in the number of pages
or number of folds imparted to the sheet.
It is one of the objects of the invention to provide, in compact form, a combined
newspaper and pamphlet printing press, which shall be capacitated to produce a
large variety of products, varying from newspaper size to that of a small pamphlet,
and in which the changes necessary for varying the products shall consist of a slight
and convenient adjustment of parts.
With this object in view, one part of the invention consists generally in the
combination with a suitable printing machanism, and cutting, collecting, and folding
cylinders, of folding and delivery mechanism whereby one or more additional
transverse folds may be imparted to the sheet, after passing the cutting, collecting,
and folding cylinders, and whereby an additional longitudinal fold may be imparted
to the sheet, the latter being delivered to one or the other of two flys and sets of
carrier tapes, the folding and delivery mechanism being so constructed that the use
of switches is entirely avoided, and the various products are obtained by a simple
adjustment of one or more parts of the operating mechanism.
Another object of the invention is to improve the general construction of delivery
mechanism for web printing machines, and to this end the invention consists, further,
of various improvements of general application in this class of mechanism, whereby
the construction is greatly simplified, its operation rendered more certain and
reliable, and a more accurate registry of the sheet secured.
Another object of the invention is to provide an improved inking mechanism
for web printing machines, and to this end the invention consists, further, in various
improvements in the construction and organisation of the mechanism for securing
the various movements of the fountain and transfer rolls and the distributing
cylinder, whereby this mechanism is greatly simplified, its size reduced, and its
operation rendered more certain and reliable, whereby a more easy and perfect
control and adjustment of the various rolls is obtained, and whereby the introduc-
tion and removal of the form rolls is greatly facilitated.
A full description of a web printing machine embodying the various parts of
the invention will now be given, reference being had to the accompanying drawings,
forming a part of this Specification, and features of invention particularly pointed

Figures 36 and 37 shew products.
Referring now especially to Figures 1 and 2, it will be understood that the
printing mechanism may be of any ordinary construction, that shewn consisting
essentially of the type cylinder A and impression cylinder B, the two forming,
together with the web turner C, a printing and perfecting mechanism of a common
form. The type cylinder A. may be furnished with an inking mechanism of any
suitable form, that shewn consisting essentially of the distributing cylinder D,
distributing rolls d, form rolls e, and the usual fountain and transfer rolls.
For imparting the necessary movements for feeding and distributing the ink upon
the cylinder D, the following construction is shewn generally in Figures 1 and 2.
The distributing cylinder D, is mounted to reciprocate in its bearings, this
reciprocating motion being imparted to it by the lever 10, provided with a bowl
engaging with a pulley on the shaft of the distributing cylinder, this lever 10 being
pivotted on the frame, and operated by means of an excentric stud on a short
shaft 12, which carries a worm wheel 13, actuated by a worm gear 14 on a
short shaft 15, which is operated from the shaft of the distributing cylinder by
suitable gears (not shewn).
The transfer roll is carried against the fountain roller by means of a cam 17 on
the shaft 12, which operates against a bowl 16 carried on the end of one of the
arms 18, supporting the transfer roll, the latter being returned by its weight, or by

page_text: suitable springs. The fountain roll is provided with the usual pawl and ratchet
mechanism for rotating it, the lever 19 carrying the pawl, being acting through the
connecting rod 20, adjustably connected to a lever 21, which is operated, at each
vibration of the lever 10, through suitable geared segments (not shown) carried
respectively by the levers 10 and 21. A lever 22, carrying a bowl engaging with
the pulley 11 on the shaft of the distributing cylinder, reciprocates one of
the form rolls d in the direction opposite to the movement of the distributing
cylinder.
This inking mechanism, in a slightly modified form, is shewn in detail in Figures 3
to 9, and this form will be described fully in connection with these figures.
The shaft 213 of the distributing cylinder D, is provided with a broad faced
gear 214, which engages with a gear. 215 mounted on a short shaft 216, which
extends through the side frame upon one side of the machine, and is provided with
a worm 217, which engages with a worm gear 218, mounted upon a short horizontal
shaft 219, supported upon the side frame. The face of the gear 218 is provided
with an excentric stud or crank pin 220, which enters a groove formed in the lower
end of a rocking lever 221, which is fulcrummed in brackets 222, secured to the
frame, and provided at its upper end with a stud or bowl 223, which extends into a
groove formed in the periphery of a pulley 224, secured upon the end of the
shaft 213 of the distributing cylinder.
This construction relieves the type cylinder shaft entirely from the strain of the
longitudinal motion of the distributing cylinder, and groups in small compass,
about the shaft of the distributing cylinder, all the mechanism for reciprocating
the same, thus economising space, an important feature in web-printing machines.
The type cylinder, also, by the removal from its shaft of all connections for
reciprocating the cylinder, can more readily be adjusted in proper position in the
machine, an adjustment which is frequently necessary in web printing machines.
The shaft 219, in addition to the gear 218, is also provided with a cam 225,
which engages with a stud or bowl 226 mounted upon the end of a rock arm 227,
which extends from a shaft 228, having upwardly extending rocking arms 229,
only one of which is shewn upon, which is supported the transfer roll. cl.
By this means, at each revolution of the shaft 219, the arms 229, carrying the
transfer roll, are vibrated so as to carry said roll from the fountain roll d¹ to the
distributing cylinder D, and thus transfer the ink from the former to the latter.
The return movement of the transfer roll is effected by means of springs (not
shewn), which are arranged and act in the usual manner. The movement of the
transfer roll toward the fountain roll is limited by means of an arm, 245 (Fig. 5),
extending from the shaft 228, and the movement of which is limited by an adjusting
screw 246. By this means, the pressure of the transfer roll upon the fountain
roll can be regulated with great nicety. The bowl 226 is mounted upon a stud
which is adjustable in the arm 227, and is provided with an adjusting screw 247,
by which the stud and bowl can be adjusted to regulate the movement of the
transfer roll toward the distributing cylinder, and thus regulates the pressure of
the roll against the cylinder. As the roll becomes gradually reduced in diameter
by shrinkage or wear (for it will be understood that the transfer, form, and
distributing rolls, are usually made of a flexible composition cast upon an iron
core), these adjustments enable proper compensation to be made for any change in
diameter.
The transfer roll is mounted to turn freely in the arms 229, in which it is
supported, so that whenever it is in contact with either the fountain roll or the
distributing cylinder, it is driven by frictional contact, and the distributing
cylinder being driven at a comparatively high rate of speed, the transfer roll
sometimes obtains such a velocity, from its contact with the cylinder, that when
vibrated back into contact with the fountain roll, its movement will be sufficient to
give a partial rotation to the latter roll, and thus produce over inking. It is
therefore desirable that the rotary movement of the transfer roll should be arrested.
or partially arrested, before it comes into contact with the fountain roll. To effect

page_text: this, the shaft of the transfer roll is provided, at one or both ends, with a
pulley 249 (see Figure 9), which is engaged by a friction brake 250, which is
supported upon an arm, 251, extending from the frame of the machine, and arranged
to engage with the pulley, as the transfer roll arrives in its mid position in its
vibration between the distributing cylinder and the fountain roll. The pulley 249
is preferably slightly excentric of the shatt of the transfer roll, as shewn in
Figure 10, so that as the transfer roll rotates by the momentum acquired from
contact with the distributing cylinder, the excentric portion of the pulley coming
into engagement with the brake, will increase the friction between the pulley
and the brake, and thus cause the brake to more easily arrest the rotation of
the roll.
The operation of this device is as follows: The transfer roll, when it is vibrated
into contact with the distributing cylinder, will be set in motion by frictional
contact with the cylinder, and this motion will continue as it is vibrated back to
the fountain roll. As the transfer roll arrives at its mid position between the
distributing cylinder and fountain roll, the pulley or disc 249 will engage with the
brake 250, and the friction thus applied to the disc will overcome the momentum
of the roll, and arrest, or substantially arrest, its rotary movement before it comes
into contact with the fountain roll.
As the transfer roll is vibrated back to the distributing-cylinder, it will have
no rotary movement, or only such slight movement as it has acquired from contact
with the fountain roll, but as the disc 249 passes in contact with the brake 250,
the brake will operate to impart a slight rotary movement to the transfer roll, so
that when the roll comes into contact with the distributing cylinder, it will already
have a rotary movement, and will thus be prevented from sliding in contact with
the cylinder, which sliding contact tends to wear the roll and cylinder, and produce
uneven inking.
Although, as shewn in the drawing, but one end of the transfer roll is provided
with the disc 249 and brake 250, it will be understood that the other end of this
roll is similarly provided. The brake 250 will preferably be so constructed as to
be slightly yielding.
Although, as shewn, the pulley 249 is V shaped on its periphery, and the brake
is correspondingly shaped, and provided with leather surfaces which are capable
of adjustment by means of screws, it will be understood that these devices may be
widely varied without departing from the invention. One of the many other forms
which may be successfully applied is illustrated in Figures 10 and 11. In this
case, the brake 250 is carried upon the end of a bar 252, which is pivoted to
the frame-work, and rests upon a stud or bowl, 253, projecting from the side of
the arm 229. The arm 252 is provided with a cam projection 254, which, as the
transfer-roll is vibrated in either direction, is acted upon by the bowl 253, so as to
raise the arm 252, and press the brake against the pulley or disc 249, and thus
arrest the roll, or give it a slight rotary movement, as the case may be.
The necessary rotation of the fountain roll d', is effected as follows: The shaft
is provided with a ratchet 230, which is engaged by a spring-pressed pawl, 231,
mounted upon a rock arm 232, extending from a sleeve 283, mounted loosely upon
the shaft of the roll. This sleeve is also provided with a rock arm 234, which is
connected by a link 235 with a vibrating arm 236, mounted loosely upon the
shaft 216, inside the worm 217. This arm 236 is provided, upon one side, with a
segment 237, which engages with a corresponding segment 238, extending from
the lever 221, and having its axis coincident with the fulcrum of said lever.
By this means, the vibration of the lever 221, operates to rock the segment 238,
and thus impart a corresponding vibrating movement to the segment 237, which
movement is imparted through the link 235 to the rock arms 234, 232, and
pawl 231, thereby causing said pawl to engage with the ratchet 230, and rotate
the fountain roll with a step by step movement, so as to deliver the ink upon its
surface to the vibrating transfer roll .
In order to vary the movement of the fountain roll to cause it to deliver a

page_text: greater or less amount of ink to the transfer-roll, which is of course necessary in
order to cause the inking to conform to the different classes of work to be produced,
the arm 236 is provided with a slot 239, through which the bolt which connects
the link 235 to the disc passes, so that the point of connection of the link to the
arm can be varied so as to give the link a greater or less amount of movement,
and thus cause the pawl to be retracted the length of one or more teeth of the
ratchet, so as to impart a greater or less movement to the fountain roll, as may be
required. The slot in the arm 236 will preferably be provided with graduations
corresponding to that of the requisite number of teeth to be moved, which will aid
in securing the proper adjustment of the bolt in the slot. As this movement is
one which causes the forward movement of the pawl to begin very gradually,
increasing to the middle of its throw, and then gradually decreasing until the end
of its stroke is reached (the return being made in the same manner), it will be
seen that as the length of stroke or movement of the fountain roll is determined
by the position of the bolt in the slot 239 (ie., being at the bottom of the slot
when the least motion is required, or at top for the greatest), the nature of
the movement is the same, and, as, in every case, the pawl is brought slowly into
engagement with the teeth of the ratchet, there is no liability of breaking the
teeth or other part of the mechanism. The link 235 is provided with a slot 240,
through which the stud connecting the link to the rock arm 234, passes, and in
which the stud is permitted to move freely, and the sleeve 233 is provided with a
hand lever, 241, which, by its weight, ensures its backward movement, and also
permits the sleeve to be operated independently of the link 235, so as to operate
the fountain roll by hand, to bring inked portions of the roll into position to deliver
ink to the transfer roll e¹ in "inking up," or when the machine is first started.
In order to properly adjust the upper form roll ', so as to cause it to bear
properly upon the form and distributing cylinders, the bearings 209, in which the
roll is supported, are made adjustable as follows:-These bearings or sockets are
secured to the frame work by means of bolts 208 (see Figures 6 and 7), which
pass through enlarged openings 207, in the bearings, but fit snugly in smaller
openings in cap pieces 206, which fit over the bearings, and are provided with
flanges 205, which extend inward at the sides and bottom of the bearings. These
flanges 205 are provided with adjusting screws 204, which bear respectively against
the opposite sides and bottom of the bearings 209.
From this arrangement it will be seen, that by loosening the bolts 208 slightly,
and then operating the screws 204, the sockets can be adjusted vertically and
laterally so as to bring the roll into any desired position with great nicety. After
the roll has been so adjusted to the proper position, the bearings 209 can be locked
by tightening up the bolts 208.
To provide for the ready introduction and removal of the lower form rolls,
the bearings 203 of these rolls (see Fig. 8) are mounted in swinging arms 242,
which are pivotted on the frame-work at 243, so as to be capable of swinging
downward and upward, to lower and raise the rolls from and into position. The
opposite ends of the arms 242 are secured to the frame-work, so as to support the
rolls in position by means of locking bolts 244 which engage with recesses in
the ends of the arms. The bearings 203 are adjustable upon the arms 242 in the
same manner that the bearings 209 are adjustable upon the framework, or in any
similar manner.
J
The manner of introducing and removing the lower form rolls is as follows:-
To introduce the rolls, the arms 242 are swung downward to a pendent position,
as indicated by dotted lines in Figure 8. The journal of one end of the roll is
then received by the usual carriage 248 (see Figure 8), and the roll is run into the
machine in the usual manner. Attendants upon each side of the machine then
swing the arms, 242, up to their horizontal position, and as the arms are thus
raised, the bearings 203 take over the journals of the roll, as shewn in Figure 8,
and raise the roll into position. The arms 242 are then secured by the locking
bolts 244. To remove the roll, the operation is simply reversed.

page_text: When it is desired, as is often the case, to simply remove the roll out of contact
with the cylinders, without removing it entirely from the machine, the locking
bolts 244 are loosened so as to permit the arms 242 supporting the roll, to be
lowered sufficiently for the purpose, when the bolts 244 arc again turned, so as to
enter the upper recesses provided therefor, and tightened as before.
Referring now to the general construction of the printing end of the machine,
the web E is led from a web roll at the end of the machine, which is provided with
the usual brake and tension devices 8, 9, and passes thence to the control of the
first series of tapes a, b. The upper series of tapes a, as shewn in Figure 1, pass
under the conducting rolls 23, and upward past the impression cylinder B, returning
round another conducting roll 23, and tightening pulleys 24, to the first roll. The
under series of tapes & pass over the conducting rolls 25, and around tightening
pulleys 26.
The operation of the printing mechanism, and the movement of the web after
it leaves the control of the tapes a, b, is the same as in similar constructions, now
well known, and need not be described here further than to say that the web
passes between the type and impression cylinders A, B at one end, where it is
printed on one side, thence over one end of the two-part conducting roll 27,
downward around the turner C, returning over the other side of the turner and
the other end of the two-part conducting roll 27, as shewn in Figure 14, thence
downward around the impression cylinder B, and upward between the cylinders A. B
at the end opposite to that by which the first impression was made, the web
thus being perfected, and passing over the conducting roll 28 to the delivery
mechanism.
It will be understood that the two parts of the roll 27 are rotated in opposite
directions by means of gears at either end of the machine, the movement of one
part being reversed by a second intermediate, as shewn clearly in dotted lines in
Figures and 12, and in full lines in Figure 13.
The operation of the web-turner is the same as usual, but the following means
of adjustment are provided. The turner C is provided at its lower end with a
fork 29 (see Figures 12 and 14), which embraces and slides on a short shaft 30,
supported in the frame of the machine, this construction preventing any swinging
movement of the lower end of the turner. The turner is supported from the
shaft 31 by forked arms 32 at each side of the machine, the arm 32 at one
.side being provided with a downward extension, forming a bell-crank lever, as
clearly shewn in Figure 32. The depending arm of this bell crank lever is
forked, and engages a grooved nut, 33, moving on a screw 33ª, provided with a
hand wheel, and supported in the frame, and which slides transversely of the
machine in a slotted plate 34 attached thereto. The shaft 31 also slides trans-
versely of the machine, and is provided at one side with an arm 35, through
which a screw 36 passes into the frame, the screw 36 being provided with a
handwheel for convenient operation.
It will be seen that by rotating the screw 33, the horizontal arm 32 of the
bell crank lever will be thrown upward, thus raising the turner C, and that
an adjustment of the turner transversely of the machine is obtained by the
movement of the screw 36, the turner being held in position vertically and
longitudinally of the machine by the slotted plate 34 and the fork 29 and
shaft 30, which, however, allow the transverse sliding movement.
Referring now particularly to Figures 12, 13, 15 and 16, the delivery end of the
machine will be described.
The web E passes from the roll 28 over the series of tapes f, and is conveyed
by them, and the upper series of tapes g, to the longitudinal folder F, from which
the web passes between the usual external turning rolls 51 and feeding rolls 52,
to the cutting, collecting, and folding mechanism. The lower series of tapes f
as shewn in Figure 12, pass from the roll 28, just in advance of the printing
mechanism, to the conducting roll 37, thence backward around roll 38, forward
around tightening pulleys 39, returning thence to roll 28. The roll 28 is mounted

page_text: in a fixed position in the main frame, while the conducting roll 37, from which
the tapes receive their motion, the roll 38, and pulleys 39, are mounted in a
frame sliding on the main frame, as will presently be described.
The upper
series of tapes are carried by the sliding frame, and pass around the tightening
pulleys 40, thence forward over the roll 37, returning around the conducting
roll 41. A slitter 42 is carried by an arm upon the transverse shaft 43, which
also supports the arms carrying pulleys 40. This shaft 43 is adjustable by
means of the arm 44, provided with a thumb screw 45, as shewn in Figure 13,
whereby the slitter may be secured in out of operative position.
As shown in Figures 13, 15, and 16, the frame G, sliding on the top of the
main frame, and carrying the feeding mechanism and slitter just described, is
provided at either side of the machine with a rack bar 46 (Figs. 12 and 16),
engaged by gears 47 upon a transverse shaft 4S, by which the frame may be
moved in either direction, carrying with it the folder and conducting rolls and
tapes, the shaft 48 being provided with a square head outside the frame for
rotating it.
The frame G is provided with a downward extension 49, which carries an
adjustable arm 50), provided with a support for the folder, as shewn in Figure 12.
The conducting rolls and slitters are driven by a system of gears shewn in Fig. 13,
and for the purpose of retaining the gears in mesh, while allowing the movement of
the frame C, the shaft of gear 3, carried by the frame, and driving the rolls and
slitter, has loosely mounted upon it a swinging arm 5, carrying the shaft of an
intermediate 4, with which gear 3 meshes. The shaft of gear 4 is mounted also in
a second arm 6, swinging on the shaft of a gear 7, mounted in the main frame and
driving gear 3 thro' the intermediate 4. The intermediate 4 is thus supported in
the arms 5, 6, and must, as the frame G moves, preserve its distance from both the
driving and driven shafts, and remain in mesh with the gears thereon.
steadying the shaft of gear 3, a plate his supported upon the end of the frame G,
and slotted to receive the shaft, this plate having an adjustable connection with
frame G by means of slots and bolts 1. The frame G is similarly secured to the
main frame by slots and bolts 2.
For
It will be readily understood that by loosening the bolts 2, and rotating the
shaft 48 carrying the gears 47, the frame ( may be moved forward and backward,
carrying with it the folder F and the series of tapes, thus securing accurate adjust-
ment for the folder relatively to the cutting, collecting, and delivery mechanism,
the swinging connections of gears 3, 4, and 7, allowing the movement of the frame
without throwing the gears out of mesh, as previously described. Upon tightening
up the bolts 2, the frame will again be locked in position.
By reference to Fig. 12, it will be understood that the movement of the frame
does not affect the tension of the lower series of tapes, on account of the manner
in which the tapes are led, as previously described, the forward or rearward move-
ment of the conducting roll 37, which tends to tighten or loosen the tapes, being
compensated for by the equal forward or rearward movement of roll 38 having the
opposite effect upon the tapes.
From the longitudinal folder F, and the rolls 51, 52, the web passes to the cutting,
collecting, and folding cylinders, which will now be described. Referring
particularly to Figs. 18 to 22, HI are the usual pair of cutting and collecting
cylinders, each of a circumference equal to the length of a single sheet. The
cylinder is provided with the cutting blade 53, and the cylinder H with the
groove 54 to receive the same. The cylinder H is provided also with the usual
sheet-holding pins c, or other suitable sheet-holding devices, which are carried by
crank arm 55, extending from the supporting shaft, and are normally held in
operative position by means of the usual crank arın 56, sliding rod 57, and
spring 58.
It will be understood that any of the ordinary forms of folding blades and
mechanism for operating the same and the sheet folding devices, may be employed

page_text: in this machine. The folding blade and operating mechanism shown is preferred,
and forms an important part of the present invention.
The cylinder His provided with a double edged folding blade, which is mounted
upon shaft 59, journaled in the heads of the cylinder, and operated to fold the sheet
or sheets carried by the cylinder, into the bite of a pair of folding rolls in the usual
nammer. The shaft 59 is provided at one end with a transverse arm 60, parallel
with the blade, and carrying two operating bowls 61 placed inside the edge of the
blade. The arm 60 extends beyond the operating bowls 61, and is provided at its
ends with heart shaped projections 62, for a purpose presently to be described.
Secured to the frame, at the end of the cylinder H, is a circular cam K, by which
the bowls 61 of the arm 60 are operated, the cam being so shaped that the folding
blade is held in position with neither of its edges protruded beyond the periphery
of the cylinder, except just at the point where the folding is to take place, that is,
opposite the folding rolls, where the cam is so shaped as to permit the folding blade
to make the required movement for folding the sheet.
Within the exterior cam K, and supported by the frame work of the machine, is
a plate L, which reciprocates vertically between guides 64 secured to the frame,
the lower end of the plate being inclined in opposite directions, so as to form a
cam, conforming in shape to the cam K at that point, and forming the interior
cam for operating the folding blade, when the plate L is in its raised position.
As the folding blade & necessarily reciprocates in approximately straight lines, as
it advances between the folding rolls and recedes therefrom, the bowls 61, if placed
opposite the edges of the folding blade, will also move in approximately straight
lines, when opposite the point of the cam m, and will be liable to return upon the
same side of the cam m, instead of passing the point and returning upon the opposite
side to complete the half revolution. It is preferable, therefore, to place the bowls
out of line with the edges of the blade, in order that while the edges of the blade
move in straight lines, the bowls may swing sufficiently to pass the point of the
cam and insure their proper return. This may be accomplished by placing the
bowls either outside or inside the edges of the blade, but it is preferable to place
them inside, as shown, as this reduces largely the path of travel of the bowls.
The blade will be controlled by the folding or nipping rolls or their equivalents,
so as to secure, with approximate certainty, the proper return of the bowls, if the
latter be placed out of line with the edges of the blade. In order to attain greater
certainty in the return of the bowls, relieve the folding rolls from the control of the
blade, and ensure a positive movement of the blade at the point of its greatest
protrusion, which is just as the bowl 61 passes the point of the cam m, and
temporarily out of the control of the cams Km, the arm 60 is preferably provided
at each end with cam surfaces, which diverge rearward from a central line, forming
a wedge or heart shaped projection 62. Just before the bowl 61 leaves the point
of the cam m, this wedge shaped projection passes between and is engaged by a pair
of cam surfaces 65, which are formed preferably by projections from the inner face of
the cam K, the blade thus being positively controlled during the folding operation,
and until the bowl 61 has been carried past the point of the interior cam, and into
the control of the cam m upon the opposite side from that by which it is advanced,
thus completing the half revolution of the blade.
The movable plate L is provided also with an inwardly projecting shoulder,
forming a cam n, which, when the plate is in its lowest position, forms a continuation
of the annular portion of the cam K, so that the advance bowl 61 upon the arm 60,
instead of being directed outward to fold the sheet, is continued onward in its
annular path, the blade not being operated, and no folding taking place, as shown
in Fig. 20.
The upper end of the plate L is provided also with a cam o, which, when the
plate is in its raised position, engages a bowl 66 on a crank arm extending from the
shaft of the sheet holding devices, and retracts the pins c, so as to release the sheet
or sheets in time to permit them to be folded by the blade k. It is evident that

page_text: when the plate I, is in its lowest position, the cam o will not operate to retract
the pins.
The plate L is slotted vertically to permit it to move over a box extending
inward from the frame, and supporting the shaft 67 of the cylinder H, as shown in
Figures 18 and 19. For reciprocating the plate L, the shaft 67 of the cylinder H
is extended through the framework, and has splined thereto a small gear 68
(Fig. 21), which may be removed from the shaft, and engages with a gear 69, of
twice its size, secured upon the end of a short shaft 70, which passes through the
framework, and is provided with a crank having a bowl 71 which enters an opening
in the plate L. The gear 69, being double the size of the gear 68, the crank makes
one revolution to two revolutions of the cylinder H, and the plate L with its cams
is raised upon one revolution of the cylinder and depressed at the next, the move-
ment being so timed that the plate will be in its respective raised and lowered
positions at the time the folding blade passes the folding rolls.
It is important that the cams mn should remain in a fixed position during the
time they are acting upon the bowls 61. To effect this, the opening pin which
the bowl 71 works, is provided with grooved recesses upon its opposite sides, in
which the bowl 71 enters as the plate L reaches the extreme limit of its movement
in either direction, thus holding the plate in fixed position during the operation of
the cams m and n upon the bowls 61.
The operation of the parts, in folding, is as follows, the different positions of the
blade and arm being shown in Fig. 22. The edge of the blade, which is in
advance relatively to the rotation of the cylinders H, as it arrives at the first of
the folding rolls, is caused to move outward beyond the periphery of the cylinder
by the cams m and K, and its movement is continued as the blade passes the rolls,
so that its edge is projected into the bite of two folding rolls, thereby imparting a
quarter revolution to the blade, the heart shaped projection 62 at the end of the
arm passing between the fixed cams 65, and controlling the movement of the arm
and blade, as the bowl passes the point of the cam m. As the movement of the
cylinder continues, the arm 60 and blade k are reversed, a half revolution being
completed by the action of the other side of the cam m and the fixed cams 65.
On the next revolution of the cylinder, the other edge of the blade performs the
folding, and the arm and the blade are reversed as before.
In this case, that is, when the folding blade is to operate at each revolution, and
the sheets are not to be collected, the gear will be detached from the shaft 67, and
the plate L will be moved to its raised position, and secured therein in any suitable
manner, as, for example, by a threaded bolt 72, which is passed through an
opening in the gear 69 and the framework, and enters a threaded opening in the
plate I, as shown in dotted lines in Fig. 19. The plate being secured in this
position, the cam will operate to retract the pins at each revolution of the
cylinder, and the cam m will remain in position to direct the bowl 61 outward, for
the operation of the folding blade.
If the sheets are to be collected, the folding blade will be operated only at each
alternate revolution of the cylinder. In this case, the bolt 72 will be withdrawn,
and the gear 68 secured to the shaft 67, as in Fig. 19. As the blade approaches
the folding rolls upon the first revolution, the crank carrying the bowl 71 will be
in position to depress the plate L, so that the advance bowl 61, instead of being
operated by the cam m for folding, will be carried onward in its annular path by the
cam n, and, as a consequence, no folding will take place, and cam n being depressed,
the pins c will not be retracted. Upon the second revolution of the cylinder, the
crank carrying the bowl 71 will be in position to raise the plate I, so that the
bowl 61 will be operated by the cam m, and the pins c will be retracted by
This operation will be repeated, folding taking place at each alternate
revolution of the cylinder.
the cam o.
If, for any reason, it should be desired to render the folding blade entirely
inoperative, the plate L will be moved to its lower position, the gear 68 being
BB

page_text: removed, when the weight of the plate will cause it to remain as positioned, or it
may be secured thus in any suitable manner.
For the purpose of guarding against the possibility of the machine being started
while the gear 68 is fast to the shaft 67, and the gear 69 and plate L fast to the
frame, in which case it is evident that serious breakage would result, locking
devices are provided, that shown being a suitable and convenient form, but
capable of modification within the invention.
The gear 68, as previously stated, may be splined upon the shaft 67, and a
holding plate 74 secured to the gear by screws, as shown in Figs. 19 and 21, and
provided with a central opening, through which a screw 75 passes, to secure the
plate and gear to the end of the shaft. The central opening in the plate 74 is
enlarged and screw threaded, from which it will be seen that by removing the
gear 75 which holds the plate to the shaft, by pressure of its head upon the plate,
an enlarged screw threaded bolt may be inserted, by turning which against the
end of the shaft, the plate 74 and 68 will be withdrawn.
Sliding upon bolts 76 in the frame, is a slotted safety plate 77, provided with
an opening 78, which, in the raised position of the plate, registers with the opening.
in the gear wheel 69, through which the threaded bolt 72 passes for securing the
gear to the frame. The safety plate 77, in its lowest position, extends upward to
the lower edge of the gear 68, and in its upper position extends partially over the
space occupied by the gear, when in position, as shown clearly in Fig. 21. When
the gear 68 and plate 74 are in position, the plate 77 is held from upward move-
ment by the plate 74, which extends outward into the path of movement of the
safety plate 77.
It will readily be seen from this construction, that it is impossible to raise the
safety plate 77 so as to insert the bolt 72, until the gear 68 and plate 74 have been
removed, and, on the other hand, it is impossible to introduce the gear 68 and
plate 74 for securing it to the shaft, until the bolt 72 has been removed, to allow
the safety plate 77 to be lowered.
The supplementary transverse folding mechanism will now be described.
The sheet is folded from the cylinder H by the blade between a pair of
folding rolls MN (see Figs. 17 and 18), the former carrying a single edged
folding blade, by which the sheet at each alternate revolution is either folded or
guided between the rolls NO, from which it passes under control of the tapes
over the guide 79, and thence to a second pair of folding rolls PQ, the former of
which carries a single edged folding blade similar to that of roll M, by which the
sheet is folded or guided between the rolls QR, and passes thence, under control
of the tapes, either directly to a fly at the side of the machine, or after
receiving a longitudinal fold, to a fly at the end of the machine, as will presently
be described.
The construction and operation of the two pairs of folding rolls M N and P Q
being the same, a detailed description of one pair will be sufficient.
Referring particularly to Figs. 23, 24, 25, the roll M, which is half the size of
the cylinder H, that is, its circumference is equal to the length of the sheet
folded once transversely by the cutting and collecting cylinders, is provided with a
single edged folding blade t, the shaft of which is provided with a transverse arm 80,
carrying two bowls 81, located inside the edge of the blade and the ends of the
arm, the arm being provided at each end with a heart shaped extension 82. At
the end of the roll, and secured to the frame, is a cam S. the inner operating
surface of which is annular, except directly opposite the point at which the sheet
is to be folded between the rolls N, O, at which point the cam is so formed as
to permit the bowl 81 and the blade to be carried forward, so that the blade
will pass between the rolls for folding or guiding the paper.
The cam S is provided with an inwardly extending flange 83, which extends
into the plane of rotation of the arm 80 and bowl 81, and the operating part of
which, as shown clearly in Fig. 23, is formed with sides inclined in opposite

page_text: directions, to form a cam e, conforming generally in shape to the cam S at that
point, and constituting an interior cam operating on the bowl 81, to direct the
bladet between the rolls N O, the arm 80 being reversed as it passes the point of
the cam.
For the purpose of controlling the movement of the arm as it passes
out of the control of the cams we and S, the cam S is provided with two inwardly
extending fixed cams 8+, between which the heart shaped ends 82 of the arm 80
pass, thus controlling the movements of the blade as the bowls pass the point of
the cam w.
It is important that the edge of the folding blade shall follow as closely as
possible the periphery of roll N as the blade advances the fold line of the sheet,
and that, on the other hand, the blade shall be thrown away from the periphery of
roll as the arm and blade is reversed. For this purpose, the arm 80 and
the blade are placed upon the shaft 85, so that the blade is not in a parallel
central position to the arm, but forms a slight angle therewith. The arm 80 with
its bowls 81 and heart shaped extensions 82, is also so constructed that a line
drawn through the centres of the shaft and bowls, will pass to opposite sides of the
centres of the projections ou the end of the arm, the blade t and the projection 82
on its end of the arm being upon opposite sides of the central line.
By the angular position of the blade relatively to the arm and its bowls, the edge
of the blade is carried inside the central line of the arm, as the folding roll M
rotates with the blade in advance, thus enabling the blade shaft to be placed close
to the edge of the roll, so as to carry the blade in a circle of substantially the same
circumference as the roll, its speed thus being the same as that of the paper.
The blade also will preferably be curved slightly, the curve being in a direction
to throw the edge of the blade inward, when in advance relatively to the rotation
of the roll M. This curve, with the angular position of the blade, enables a longer
blade to be used, and the curved blade follows more closely the periphery of
roll N.
By reference to Fig. 23, in which the arm and blade are shown in three positions,
iz. as they approach the folding point during the operation of folding, and after
the arm has been reversed, the operation of this construction will readily be
understood.
As shown in this Figure 1 the blade t, during the folding revolution, is carried
with its edge close to the periphery of the roll M, thus travelling at the same
speed as the paper fed by the rolls M N. As the blade reaches the folding point,
it will be carried forward by the cam re, with its edge close to, and moving in a
circle concentric with the periphery of roll N, the projecting 82 engaging the
cam 84, and, by its shape and position, guiding the blade in the same course as it
passes out of the control of the cams w and S. As the arm passes the point of the
cam, it will pass into control of the opposite side of the cam te, and the cam S, and
a half revolution of the arm will be completed, the arm then being reversed, and
the blade being inoperative during the next rotation of the roll M.
The shape and position of the projection 82, and the angular position of the blade,
operate to throw the edge of the blade away from the roll O, as the folding
movement of the blade is completed, and the blade commences its movement
away from the rolls N O, this position of the blade being continued by the
cam w, as the arm passes into its control. To aid in this movement, the lower
cam 84 is placed at a slightly greater distance from the shaft of roll M than the
upper cam.
The shaft of roll M, as shown in Fig. 23, is grooved in the plane of rotation of
the arm 80, to allow the extension 82 to pass the shaft as the arm is reversed.
The blade is adapted to operate either as a guiding or folding blade, and as a
folding blade to fold the sheet either on the central line, or at one third or
other part of its length from the end. For the purpose of adjusting the roll M and
its blade, so that the blade shall operate in either of the ways just referred to, the
following means are provided :-
:-
The roll M is driven from the cylinder 1 by means of a gear 86 (see Fig. 16),

page_text: When
which is mounted loosely upon a stud set into the frame, and is held, in its outward
position, in mesh with the gear of roll M by means of a sleeve 88 secured between
the gear 86 and the frame by means of a set screw 89, as shown in Fig. 33.
it is desired to adjust the position of the roll M, the screw 89 will be withdrawn,
and the sleeve 88 removed from the shaft. The gear 86 may then be moved
toward the frame out of mesh with the gear on roll M, and by similarly loosening
the 93 by which roll P is driven from roll M, the latter and its blade may be
adjusted to any desired position.
The roll P is provided likewise with a single edged folding blade, the shaft of
which is provided with a transverse arm 90 (see Fig. 13), provided with bowls and
heart shaped projections similar to those described in connection with roll M, the
blade being operated by an exterior cam T and interior cam and fixed cams,
the construction and operation of the parts being identical with those of
roll M. This roll P is operated from the roll M by means of the intermediate
gear 93 (Fig. 16), which is provided with means similar to those described in
connection with the gear 86, whereby the gear may be moved out of mesh for the
adjustment of the roll 1, to bring its folding blade into either of the positions
previously described, the gear 158 on shaft of roll P being removed or loosened, to
avoid rotating the slitter to be described hereafter.
A curved guide 122 is provided, by which the end of the sheet, as it passes
between the rolls M N, prior to folding, is curved outward, thus permitting
it to be more readily folded between the rolls N, O, and the sheet is carried from
these rolls to roll 1 by a series of tapes r, passing over a guide 79, and between
rolls PQ, these tapes forming the upper series of the delivery tapes.
The upper series of tapes r, as shown in Fig. 17, pass from a conducting roll 94
over tightening pulleys 95, under a conducting roll, to the folding roll N, thence
downward around the roll O, over the guide 79, and around the folding roll Q,
returning thence to roll 94. The lower series of tapes s pass from the conducting
roll 96 around the folding roll R, thence under a conducting roll 197, and over
tightening pulleys 198 to the roll 96.
If the sheet is not to receive a second longitudinal fold, it. passes, under the
control of tapes s, from the rolls QR, between which it is folded by the folding
blade on roll P, to the fly 97 at the side of the machine, by which it is delivered
against the stops 98 upon the carrier tapes 99.
For the purpose of imparting a second longitudinal fold to the sheet, a pair of
folding rolls Vextend in the line of motion of the tapes, and above them is mounted,
in suitable supports in the frame, the folding blade Z, adapted to fold the sheet
between the rolls V, whence the sheet, folded twice longitudinally, passes to
the fly 101 at the end of the machine, and is delivered on the carrier tapes 103
against the stops 102.
Above the tapes s are placed a series of stops 104, carried in brackets upon a
shaft 105, extending longitudinally of the machine, or transversely to the line
of movement of the tapes. These brackets are adjustably secured upon the shaft
by set screws, and the shaft 105 may be adjusted by arm 120 (Figs. 15 and 16),
and held by thumb screw 121, entering the frame either so that the stops 104 are
in their upper position, as shown in full lines in Fig. 17, in which case the sheet
passes freely beneath them to the fly 97, or in their lower position, as shown in
dotted lines in the same figure, in which they act to stop the sheets, thus
co-operating with the folding blade Z, to form the second longitudinal fold. These
stops are slotted and adjustable in their brackets in the line of movement of the
tapes, being held in position by thumb screws 123, the stops being thus positioned
for sheets of different lengths.
The folding blade Z is carried by cranks 106 mounted on shafts 107 in the frame
of the machine the cranks 106 being preferably bell cranks, as shown, one arm of
each being pivotally connected to the blade, and their other arm being connected
to rod 108, thus insuring certainty in the action of the blade and relieving the
strain upon it. One of the cranks 106 is loose upon its shaft 107, and the other is

page_text: secured to its shaft, which is provided with a crank arm 109 (Figs. 16 and 17), to
which is connected an operating rod 110. The mechanism for operating the
folding blade positively during its entire movement, and for holding the blade out
of position when it is not desired to fold the sheet a second time longitudinally, is
as follows:-
As shown in Fig. 16, a gear 111 is provided with a crank pin upon its side, thus
forming a crank wheel, and the arm 110 is provided with a hook and set
screw 112, by which the arm may be secured to a pin upon the frame, thus
holding the blade in its upper, inoperative position, this position of the arm being
shown in full lines in Fig. 16, or by which the arm may be secured to the crank
pin upon the gear 111, as shown in dotted lines in the same figure, thus operating
the blade Z at each revolution of the gear, through crank 109 and shaft 107.
To allow the operating to yield in case of a choke, thus preventing breakage,
and to give a yielding pressure to the blade, the arm 110 is made in two parts, an
outer cylinder connected to the crank arın 109, and a rod 125 sliding therein, and
carrying the hook 112. A coiled spring 126 is inserted in the cylinder, and is
attached at one end to a collar 127 on the rod 125, its other end being held against
the end of the cylinder. This construction is shown fully in Fig. 34.
י
In the operation of sheet folding mechanism, it is found that, in folding a sheet
transversely to a line of previous fold, especially when the sheet consists of many
plies, wrinkles are formed in the sheet on both sides of the fuld line at and near
the bight of the previous fold of the sheet.
This difficulty is avoided by the use of a slitter, which is constructed and
arranged to slit the bight of the sheet prior to or during the process of folding
and on the fold line, the slit extending inward but a short distance, sufficiently to
allow the slit edge to open slightly on the fold line, as the fold is inade, as shown
in Fig. 37.
The slitter and mechanism for operating may be of any suitable form, it being
evident that both may be varied widely. A simple and convenient construction for
this purpose is shown particularly in Figs. 12, 16, 17, and 35.
Referring to these figures, 147 is a shaft supported in the rear of the folding
blade Z in the brackets 148, 149. This shaft 147 has adjustably secured thereto
arms 150, in which is loosely mounted a shaft 151, carrying the rotary slitter 152.
This shaft 151 is provided with a small gear 153, which engages with a gear 154,
carried by a sleeve 155, loose on the shaft 147. This sleeve 155 carries also a
gear 156, which engages with a gear 157, mounted on a stud in the frame, and
engaging gear 158, carried by the shaft of roll P, this gear 158 preferably being
made removable for a purpose hereafter explained. The shaft 147 is provided also
with a crank arm 159, preferably adjustable upon the shaft, as shown. To the end
of the crank arm 159 is connected a pitman 160, provided at its end with a hook 161,
by which the pitman is secured to the crank pin 162 on the gear 157. The
pitman 160 may be detached from the crank pin 162, and swung into position to
engage with and be secured to pin 163 (Fig. 16) upon the frame, by which the
shaft 147 will be rocked, to carry the slitter 152 out of position for operation upon
the sheet. The operation of the device will readily be understood from the
drawings and a brief description.
As cach sheet passes from the folding rolls P, Q, R, to a position to be operated
upon by the folding blade Z, the rotating slitter 152, by the rocking of the
shaft 147 by the crank wheel 157, will be carried into position to slit the bight of
the sheet for a short distance, the further rotation of the crank wheel 157 rocking
the shaft so as to carry the slitter 152 out of position to engage the sheet, the
operation being repeated as the next sheet reaches the same point.
If the sheet is to be delivered at the side of the machine without the second
longitudinal fold, the pitman 160 may be detached from crank pin 162, and secured
to pin 163 upen the frame, when the slitter 152 will be thrown above the plane of
movement of the sheet, and held in this position, the sheets thus passing onward

page_text: Doing s
The gear los also may be removed to stop the rotation of the
slitter.
If it be desired to slit the entire sheet without folding, so as to deliver two sheets
to fly 97, the gear 158 on the shaft of roll P will first be loosened or removed from
the shaft, the gear being secured to the shaft by a set screw, as shown, or in any
other suitable manner. The slitter then may readily be adjusted to the required
position by rotating gear 157, and rocking the slitter-carrying arms, until the slitter
is positioned to slit the entire sheet during its throw, when the gear 158 will be
tightened or replaced on its shaft. In the same way, the slitter may be adjusted to
slit the edge of the sheet to any extent required.
The slit will generally be required only upon one edge of the sheet, that which
has received the last fold. When the sheet consists of many plies, however, it may
be found desirable to slit the bight at both edges, for which it is evident that the
slitter may readily be arranged, the operation of the slitter on one or both edges
depending on the relative movements of the sheet-feeding and slitter-rocking
mechanism, which may be varied as desired by changing either the gears or form
of the connections between gear 157 and pitman 160.
In the operation of cutting, collecting, and folding cylinders, as heretofore con-
structed, it has been found that in the process of collecting, the under sheet upon
the cylinder has a tendency to back up under the tension of the outer sheet or the
web as it is received upon the cylinder, this often resulting in the rear edge of the
sheet being carried backward over the cutting groove, so that in the severance
of the second sheet, a narrow strip is cut from the under sheet, which is objectionable
for many reasons.
To avoid this objectionable feature, the following mechanism is provided:-As
shown in Figs. 16, 26, and 27, a shaft 113 is supported in the frame, and extends
longitudinally of the machine above the cutting and collecting cylinder H, from
which cylinder the shaft 113 is driven by means of gear 114. This shaft 113
carries a tucking blade 115, supported by arms 128 extending from bosses 129;
adjustably mounted upon the shaft 113, and secured in position by means of set
screws as shown or in any other suitable manner. The gear 114 is splined to
the shaft 113, so that the gear may be moved out of mesh with the gear on
cylinder H, and secured in position by a pin 116 in the side of the frame entering
a recess in the hub of the gear, this locking the gear in inoperative position,
the sleeve by which the gear is carried being provided with a set screw, by which
it may be secured upon the shaft in any desired position. The pin 116 and récess
are so placed that when the pin enters the recess, the shaft 113 will have been
rotated, so that the tucking blade 115 is carried out of engagement with the
cylinder H, and is then held in this position by the locking of gear 114, the blade
being in operative position only when the sheets are to be collected.
clearly in Fig. 26, the gear 114 and the tucking blade are so timed in their move-
ment relatively to the cylinder H, that the blade 115 enters a groove 117 formed
in the latter cylinder, just in advance of the cutting groove, thus operating to
tuck and hold temporarily within the groove the rear end of the sheet, drawing
the sheet away from the cutting groove, and carrying its end down into the
groove 117.
As shown
It may happen that as the blade 115 is drawn from the groove 117 by the
movement of the cylinders, the end of the sheet will be drawn or will fly out of the
groove 117, the end thus being carried back over the cutting groove. To prevent
this, the groove 117 is provided preferably with a shoulder 9, which extends over
the rear side of the groove, and against which the end of the sheet is held, thus
preventing its passing out of the groove.
There are also provided a series of guards 118, formed preferably of wire, or
narrow strips of sheet metal, curved around the cylinder H, and extending
forward nearly to the point at which the web passes between the cylinders HI,
these guards serving to hold the collected sheet to the surface of the cylinder as the

page_text: tucking blade is withdrawn, and to prevent buckling of the sheet between the
groove 117 and the end of the guards, all slack in the paper thereby being trans-
mitted beneath the guards to the groove 117, and taken up as the end of the sheet
is tucked into the groove, as previously described. It will be understood that the
blade 115 is recessed opposite the guards 118, to permit the blade to enter the
groove. The guards 118 are carried by supports 119, adjustably mounted upon a
shaft 130, and held in position thereon by thumb screws 131, these supports
carrying also guards 132 extending about the cylinder H in a direction opposite to
that of the guards 118.
In the operation of web printing machines in which the paper, as is usual, is led
to cutting, collecting, and folding cylinders; one of which carries a set of sheet
holding pins by which the shects is seized and carried about the cylinder, it is
found that occasionally after the web has been seized by the pins as it passes
between the cylinders, it will be removed therefrom, thereby interfering with the
operation of the machine, by causing a choke, or otherwise. This occurs in some
cases independently of any special manner in which the web is led from the folder
to the collecting cylinders.
In machines, however, in which a longitudinal folder of the form shown is
employed, it is found that the best results are obtained when the folder is so
positioned that the web does not pass from the folder to the feeding rolls in a
direct vertical line, but, as shown in Fig. 26, at a small angle to the vertical, the
web moving slightly towards the front end of the feeding rolls. With this
arrangement of the folder, it is found that a slight slack will occur in the rear
edge of the web as it passes from the feeding rolls 52 to the cutting and collecting
cylinders, on account of the return of the web to a vertical movement by the
action of the cylinders, and this slack causes an increase in the tendency of the
web to be thrown off the pins c, when the leading edge of the web has passed
between the cutting and folding cylinders. For the purpose of avoiding this, and
for the purpose of taking up the slack resulting from the position of the folder, the
following mechanism is provided :-
:-
Referring to Figs. 26 to 31, a shaft 133 is supported in the frame of the
machine by a bracket 134, and carries a deflecting guide W, formed preferably
from a sheet of thin spring metal bent at its lower end, by which it engages the
web, as shown in Figs. 26 and 31, or otherwise formed so as to prevent a sharp
edge being brought in contact with the web. This shaft 133 extends longitudinally
of the machine between the feeding rolls 52 and the cutting and folding cylinders HÍ,
and is preferably unsupported at its rear end, its front end being adjustably
supported in the bracket 134 by the means shown fully in Fig. 28, in which the
shaft 133 is adjustably secured in a sleeve 135 by means of the thumb screw 146,
this sleeve carrying a pin 136 which enters an opening in a horizontal arm of the
bracket 134, and is adjustably secured therein by means of a thumb screw 137.
By this means, the shaft 135 may be swung horizontally to any desired position,
the shaft thus being placed at an angle to the web, for a purpose presently to be
described.
The blade W is carried by a sleeve 138 upon the shaft 133, which sleeve is
loosely mounted upon the shaft, and provided with a slot 139, the ends of which
engage with a pin 140 upon the shaft, to limit the movement of the sleeve and
blade thereon. Upon the shaft 133 is coiled a spring 141, one end of which is
secured to the sleeve 138, and the other end to a collar 142 adjustably secured
upon the shaft 133 by means of a set screw 144. It is evident that by this
construction the spring 141 may be adjusted so as to press the blade W against the
web E with any desired pressure, this pressure being adjustable also by the
connection between the shaft 133 and sleeve 135.
In place of the adjustable shaft 133 by which the blade W can be placed at an
angle to the web, the shaft 133 may be rigidly supported in the bracket 134, and
the blade W be constructed as shown in Fig. 30, being of a triangular form, so as
to press slightly, or not at all, at the front edge of the web, but extending downward

page_text: from the shaft at the rear edge of the web, so as to press sufficiently thereon
for the required tension. In some cases it may be found that a tension on only a
narrow strip of the rear side of the web will be required. In this construction, the
shaft 133 may be supported at its rear end also in a bracket 145 secured to the
frame of the machine."
The sleeve 138 carrying the blade W may be secured directly to the shaft 133,
and the blade W be constructed of sufficient elasticity so as to give the required
tension without the use of the spring 141, the sleeve and blade being then adjusted
only by the rotation of the shaft 133 in the supporting bracket, being secured in
the desired position by means of the screw 146, as shown in Fig. 30. The operation
of this device is as follows:-As the web is led from the folder in the direction
shown in Fig. 28, and passes from the rolls 52 to the cylinders H. 1, the tension of
the cylinders H upon the web E tends to return the web to a movement in a
direct vertical line, and this will cause a slight slack at the rear edge of the web.
The blade W of Fig. 28 will then be adjusted, by the horizontal rotation of the
supporting pin 136 in the bracket 134, to a position in which the pressure of the
blade W upon the web E, and its angular position relative thereto, will be just.
sufficient to take up the slack at the rear edge, and to deflect the web slightly, so
as to cause an upward tension thereon, which will operate to draw the leading
edge of the web against the cylinder H, thus forcing the edge of the web inward
to the base of the pins, and preventing its being thrown off the same. Independently
of the angular movement of the shaft 133, the deflecting guide W may be
adjusted to the required tension by the adjustment of the shaft 133 in sleeve 135,
or by that of spring 141, as previously described.
The operation of the construction shown in Fig. 30 is the same, except that the
blade and shaft are placed parallel with the web widthwise, and the excess of
tension at the rear edge of the web is produced by the greater width of the
deflecting guide at that point.
It is obvious that the deflecting guide W, by which a tension upon the web is
produced, tending to draw it down to the base of the sheet holding pins, may be
employed independently of the means devised for adjusting or forming the same,
so as to take up the slack in the rear edge of the web, and such a deflecting
guide, independently of the special direction in which the web is led, forms a part.
of my invention.
It will be understood that all the mechanism described is driven by suitable
trains of gearing from the power shaft 123 at the delivery end of the machine.
This gearing is shown in the drawings, but need not be described herein.
The general operation of the machine in connection with various products will
now be described, it being understood that the number and arrangement of the
forms on the type cylinder A will be varied in accordance with the use of the press
as a newspaper or pamphlet press, and that the additional transverse and longi-
tudinal folds imparted to the sheet, after passing the cutting and collecting
cylinders, may be for the production of a newspaper folded in smaller compass, or
of a product of a larger number of pages.
For a product having one longitudinal and one transverse fold, or an eight page
product, the collecting mechanism of cylinder H will be thrown out of operation,
the plate L being positioned so that the blade & will be operated to fold the sheet
at each revolution of the cylinder, and the pins e similarly retracted the folding
rolls M and P will be adjusted out of folding position, but so that their blades will
guide the leading edge of the sheet between their respective rolls, all as described
above, and the sheet folded once longitudinally and once transversely will pass from
the last pair of rolls under control of the tapes rs, and be deposited upon the fly 97
and carrier tapes 99 at the side of the machine, the blade Z and the stops 104
being in operative position.
For a product folded once longitudinally and twice transversely, or a sixteen
page product, the adjustment will be the same as for the eight page product, except
that one of the folding rolls M, P will be adjusted to fold the sheet received from the

page_text: cylinder H, upon its central line. In this case, the sheet folded once longitudinally
and once transversely by the longitudinal folder and cutting and collecting cylinders,
will receive an additional transverse fold from the folding blade of the roll M or P,
and thence pass, as before, to the fly 97, and carrier tapes 99 at the side of the
machine.
For a product having one longitudinal and three transverse folds, or a thirty two
page product, the adjustment will be the same as in the case of a sixteen page
product, but both cylinders M P will be adjusted to fold the sheet received by
them upon its central line. In this case, the sheet folded once longitudinally and
once transversely by the longitudinal folder and the cutting and collecting cylinders,
will receive two transverse folds from the folding blades of the rolls M P, and will
pass from the cylinder P to the fly 97 and carrier tapes 99 at the side of the
machine, as before.
For a product having the longitudinal, three transverse folds, and an additional
longitudinal fold, or a sixty-four page product, the adjustment of all the folding
cylinders will be the same as in the case of the thirty-two page product, but the
folding blade Z will be brought in operative position by the connection of the
arm 110 with the gear or crank wheel 111, as previously described, and the stops 104
will be thrown downward into position to stop the sheet as it passes forward under
control of the tapes rs. The blade Z will then operate to fold the sheet longi-
tudinally between the rolls V, whence, folded once longitudinally and three times
transversely, and with an additional longitudinal fold from the folding blade Z, the
sheet will pass to the flys 101 and tapes 103 at the end of the machine.
In all products above described, the folding blades of the rolls M and P have
been adjusted either to guide the leading edge or to fold on the central line of the
sheet, the product of an additional fold being in each case of double the number of
pages of the preceding product.
For the twenty four page product shown in Fig. 36, the cylinder H will be
adjusted as described in connection with the preceding products, that is, to fold at
each revolution of the cylinder. The folding roll M, however, will be adjusted so
that its blade will fold the sheet received from the cylinder H, not upon its central
line, but on a line one third of the length of the sheet from the leading edge thereof,
this roll thereby transmitting the sheet through the rolls N. O. to the roll P with
one additional transverse fold of one third. The roll P will be adjusted to fold the
sheet thus received from cylinder N, so as to form another fold of one third the
length of the sheet as it left the cutting and collecting cylinders, thus completing a
product consisting of 24 pages. The sheet folded thus once longitudinally and
three times transversely, passes under control of the tapes to the fly 97 and tapes 99
at the side of the machine.
For a product of 48 pages, the cylinder H and rolls M and P will be adjusted as
in the case of the twenty four page product, but the longitudinal folder will be
brought into operative position, and an additional longitudinal fold imparted to the
sheet, thus forming 48 pages.
It will be understood that by the operation of the plate L through the gears 68,
69 and shaft 70, as previously described, the cylinder H may be adjusted to collect
the sheets as they pass from the longitudinal folder F, any of the products above
described thereby being doubled, so that the machine is capacitated for products
consisting of two sheets folded once longitudinally and either once, twice, or three
times transversely, with or without an additional longitudinal fold, and the highest
paged product of the machine is one consisting of two sheets of 64 pages each, or a
complete product of one hundred and twenty eight pages.
While the products above described are the main products of the machine, it
will be evident to one skilled in the art, that many other variations in product
may readily be made and that the products described may be produced by other
adjustments.
Thus, if a four page product is desired, a web of half width may be used, thus

page_text: F
.
printing and perfecting four pages, the web in this case not being folded by the
longitudinal folder E, but passing over the side of the same to the cutting, collecting,
and folding cylinders H I, by which the sheet is severed, and folded once trans-
versely, and passing thence without additional fold to the carrier tapes 99 at the
side of the machine.
The second longitudinal fold may be imparted to products having either one or
two transverse folds, if desired, thus varying further the form of the products.
If a small pamphlet of a large number of pages be desired, it is evident that
either by the addition of a cutting mechanism to this machine, or preferably by an
independent cutting machine, the sheets are received from the longitudinal folder Z
and rolls V may be severed transversely, two or more products of 96 or 128 pages
each thus being formed, this depending on the size of the machine, and upon the
position of the forms upon the type cylinder.
The slitter 42 may be thrown into operative position when desired, two sheets
being thus transmitted to the folder, and a pasting mechanism may be added to lay
a line of paste along the side edge or central line of the sheet.
Other attachments common in web printing machines will readily suggest them-
selves as adapted for use with this machine. They are omitted herein, in order
to permit a clearer illustration of the special features constituting the present
invention.
It will be understood that a printing mechanism of any suitable form may be
used in connection with the delivery mechanism of this machine, and that the
specific improvements in inking, feeding, cutting, collecting, and folding mechanisms
above described, and which will be claimed hereafter, are of general application in
such mechanisms.
No claim is made herein to the folding blade Z, and the connections between it
and shafts 107, except in combination with the special means for oscillating said
shafts, so as to actuate the blade positively during its entire movement.
