WILLIAM CONQUEST of Tudor Street in the City of London, Mechanical Engineer
"IMPROVEMENTS IN SHEET DELIVERY APPARATUS FOR PRINTING MACHINES
[communicated to him from abroad by Messieurs R. Hoe and Company of the City
and State of New York United States of America]
The improvements embraced in this invention are especially designed to be used
in combination with web perfecting printing machines, which machines, in their
present improved state, consist of two principal sets of mechanisms, viz., the
printing mechanism and the delivery mechanism. The printing mechanisms of
such inachines have for many years remained substantially the same, consisting,
essentially, of horizontally arranged printing and impression cylinders capacitated
to run at a high rate of speed and to print the opposite sides of a web or long
length of material, which printing capacity is alone limited by that of the delivery
mechanism, whose function it is to divide the web into short lengths or sheets and
deliver the same properly piled. A great variety of delivery mechanisms capable
of running at high speed, and thus adapted to be combined with such printing
machines, have been devised, and during more recent periods these delivery
mechanisms have been so constructed as not only to deliver the sheets open or flat
at high speed, but fold them one or more times during such delivery.
The present improvements relate to that class of delivery mechanisms for rotary
printing machines which deliver the sheets in a folded condition.
It is well known to those skilled in the art of printing as carried out in rotary
"web printing machines," in which the web is cut into sheets after it is printed,
that the printing surface covers the circumferential extent of the cylinder, and

page_text: that therefore any change in the size of the printing surface can only be made in
the direction of the length of the cylinder.
Now, in producing newspapers and similar periodicals, for which the web
printing machine is largely used, the direction in which their first fold should be
given depends upon several conditions; first, whether the sheets are printed from
columns running around or parallel with the axis of the printing cylinder; second,
whether the sheet be a four page paper or an eight page paper; third, also, whether
the eight page sheet be folded intact or composed of two separate four page sheets.
From this it will be seen that the first fold in some cases should be a longitudinal
one, and in other cases a transverse one; and these improvements enable one and
the same mechanism to fold, (1):-first longitudinally, the subsequent folds being
preferably at a right angle thereto and also to each other; (or 2):-first trans-
versely, and the subsequent folds at a right angle thereto and to each other.-Two
sheets may be collected one upon the other, and said collected sheets, or signature,
may be folded, 1):-first longitudinally, the subsequent folds being at a right angle
thereto and to each other, or, (2): first transversely, the subsequent folds being at
a right angle thereto and to each other. If it should be desired that at any time
the number or width of columns should be increased or diminished, then the
columns must lie parallel with the run of the paper and around the type cylinder ;
but if, on the contrary, it should be desired to lengthen or shorten the columus,
then they must lie transverse to the run of the paper and parallel with the axis of
the type cylinder.
The same printing machine may sometimes be required to print a paper from a
form the columns of which run around a cylinder, or froin a form the columus of
which run lengthwise of the cylinder, and it may be desirable, in the one case, to
make the first fold in one direction, and in the other case, to make the first fold in
the opposite direction.
In this invention, as illustrated and combined with a printing machine, the first
folding mechanism is one that gives the sheets a transverse fold, and the next
folding mechanism one that gives the sheets a longitudinal fold; but the transverse
folding device is so arranged that it may at pleasure be thrown out of operation
and become simply a carrier. Thus, the first fold the sheet will receive may be
either a transverse or a longitudinal one.
The paper having been printed in any of the usual modes, is passed to the
primary folding mechanism, or that one which is capacitated to fold the paper
transverse to its direction of travel. This mechanism consists of a rotating carrier,
(preferably a cylinder), the periphery or shell of which is perforated to accommodate
the protrusion of the various mechanisms it carries, the shaft of which is journaled
in the frame-work, and provided with a driving toothed wheel, meshing with a
wheel, whereby said carrier is caused to rotate with the same surface speed as that
of the printing mechanism.
In the construction of the primary folding mechanism, which will preferably
be used in practice, because of the simplicity and compactness of its parts, the
carrier is provided, at one point of its periphery, with a folding blade, mounted to
turn with a shaft that is journaled in the carrier heads, said shaft supporting
Said

may be readily removed and replaced by any common
extended through one head of the carrier and provided with two opposed rock
arms, one of which, during each revolution of the carrier, engages a guide way or
cam path formed by a flying cam, and a stationary cam that is fast to the frame
work. This flying cam is mounted upon the face of a toothed wheel that is
carried by a short stud journaled in the frame work. This wheel, and consequently
the cam, is rotated in proper time by means of a toothed wheel or driving pinion,
fast upon the shaft of the carrier, said flying cam being thereby rotated so as to
co-operate with the stationary cam in directing the rock arm of the folding blade
through a cam groove that will cause the blade shaft to make a semi-rotation, and

page_text: one blade to be thereby protruded from, and withdrawn into the carrier, during
which movement it enters the space between the rollers and accomplishes the
folding operation. It will be understood that although the blade shaft makes a
semi-rotation at each revolution of the carrier, such rotation becomes an idle or
Linoperative one when one blade is removed, or the folder has a single folding blade.
At a point opposite to that in which the folding blade is mounted, the carrier is
provided with a shaft from which cooperative tingers project outwardly. These
fingers are adapted to lie closely upon, or in the periphery of the carrier, and their
carrying shaft, projecting through one head of the carrier, is provided with a rock
arm, one end of which bears upon a spring which acts to close said fingers down
onto the periphery of the carrier, while its other end, carrying the stud or friction
roller, protudes so as to be engaged at proper times by means of cams secured to
the face of the toothed wheel, which is provided with means for fixing it in the
side frame in one of two positions. This wheel, in either position of its adjustment,
remains geared with its driving pinion, which is fast upon the shaft of the carrier.
One of the cams with which this wheel is provided is constructed so that it may
be attached to said wheel and be readily removed therefrom by any common means.
It is obvious that in either position of its adjustment, this cam wheel will rotato
and bring one of its cams into position to intercept the rock arm, and thus, pressing
it outwardly, cause the fingers to be raised from the periphery of the carrier, and
this movement will be produced when the fingers are passing the rollers, or a point
opposite thereto, at each revolution of the carrier, or each second revolution thereof,
according to the position in which the cam wheel is adjusted to the frame, and
according as it carries one or both of the cams. This carrier is also provided with
pins which protrude through holes in its surface, and through holes in fingers
provided therefor, which pins are secured to a shaft, that is mounted in the heads
of said carrier, so that when the fingers operate to strip the paper therefrom, they
will be slightly rocked in the direction of the outward movement of the fingers,
and thus remove the paper from said pins without enlarging the perforations or
tearing it. This carrier is constructed so as to form one of a pair of cutting
cylinders, it being for that purpose provided with a cutting edge or knife, which
co-operates with a projection or breaker or blade, carried by a companion carrier,
that is mounted in the frame below the first carrier, and geared thereto by a
toothed wheel, so as to run in unison therewith. The companion carrier is also
provided with recesses, to receive the points of the pins.
The rollers which aid in the folding operation are suitably journaled in the
framework, and will be provided or not, as necessity may require, with gear wheels,
causing them to run in unison, and with a surface speed equal to, or in some cases
faster than, that of the carrier, which they may obtain by proper gearing.
A set of guides are mounted upon a shaft, by means of which they may be
adjusted to co-act with fingers and guide sheets from the surface of the carrier
directly into the nip of the rollers, their ends being properly curved for this
purpose, and their shaft provided with a rock arm and holding screw.-Each
printed sheet, which may constitute a whole product, will simply be severed from
the web by the mechanisms of the carriers and conducted outward while extended
their full length or flat. In this operation, although the cam wheel carries two
cams, it is apparent that the wheel or the cains might be secured in a fixed
position, so that one cam would cause the movement of the fingers each time that
they pass the rollers. In consequence of the other operations carried on by this
mechanism, in which it is necessary that the fingers be operated at only every
second revolution of the carrier, the actuating cams are secured to the cam wheel,
which is twice the size of its driver, said driver being a tooth wheel secured to
the shaft of the carrier. The carrier will make two revolutions while the wheel
makes but one, thus presenting the same cam, in acting position at every alternate
revolution of the carrier.
If now it be desired to change the arrangement of the printing plates carried
by the type cylinders, and so place them that each sheet printed thereby will ba

page_text: the component half of a complete product, in which case it would be desirable to
bring two successive sheets one upon the other, or if, for any other reason, it is
desirable to collect two sheets one upon the other, it is but necessary to remove
one of the cams from the wheel, which permits the rock arm of the fingers to pass
that point without being moved. The pins thus carry the first sheet entirely
around with the carrier, and cause the same to receive the second sheet upon it,
the two then being impaled on the pins, and the cutting instrumentalities of the

cain will be then in proper position to engage the rock arm of the fingers and
vibrate the same outwardly, thereby stripping the ends of the two combined sheets
from the pins, and entering them simultaneously into the bite of the rollers.
If, now, it is desired to fold the sheets transversely, either singly or in gathered
pairs, the same may be accomplished by bringing into action the folding blade,
which may be done by simply restoring its flying or actuating cam into its
operative position, and the position of the cam wheel (now provided with both its
cams) will be changed. In this arrangement of the parts, the cams upon the wheel
will so operate that at cach revolution of the carrier the fingers will be vibrated
outwardly to release the end of the sheet in passing the point nearly opposite to
the rollers, thus carrying each sheet onward far enough to present its middle
portion, or that part which is to receive the fold, properly before said rollers. The
folding blade will make semi-revolution at each rotation of the carrier, and one
of its blades be protruded between the rollers at each rotation of said carrier.
will therefore be understood that each sheet engaged by the pins will be carried
past the rollers, and be folded by the operation of the folding blade into the nip of
said rollers, the fingers being vibrated at the proper time to release the forward
end of said sheet to enable it to pass between the rollers in a once folded condition,
which fold will be transverse to the run of the web, and each folded sheet may
then be delivered by the tapes.
It
If it is desired to collect two sheets one upon the other, and to fold the same
simultaneously with a transverse fold, one cam is removed from the cam wheel,
and one blade from the folding blade. The first sheet will be carried by the pins
around with the carrier, the cam wheel then so rotating as to admit the rock arm
of said fingers to pass by it without being acted upon, and the folding blade shaft
making that balf of its révolution which turns the single blade it then carries
inwardly as the rollers are passed. The second sheet is received upon the first, as
heretofore explained, the web is severed, and the two sheets, impaled upon the
pins, are carried onward past the rollers, and when the middle portion or folding
point of such collected sheets arrives before said rollers, that revolution of the
folding blade shaft is made which protrudes the single folding blade outwardly,
whereby the two sheets are simultaneously doubled into the nip of the rollers, the
vibration of the fingers, to release the leading ends of the two sheets, being caused
at the same time. It will also be understood that when it is desired, the pins
may be turned inwardly and rendered inoperative, and also, that the projection on
the second carrier may be removed, when the cylinders would be empty carriers.
A modified construction of devices for effecting these same operations will now
be explained. In this arrangement, the carrier is provided with a single folding
blade, that projects from the shaft, which shaft is adapted to be vibrated, so as to
swing the folding blade, such movement being imparted by a single rock arm,
whereby said blade is protruded at proper times beyond the periphery of the
carrier for co-action with the rollers.-The longitudinal row of pins is arranged to
be automatically protruded beyond, and drawn within the periphery of the carrier,
or to be fixed in either their protruded or withdrawn positions. For this purpose
they may be secured to a plate or bar, arranged to slide in ways provided within
the carrier. In this structure, a spring will be arranged to so rock the shaft us to
cause it to protrude the pins, its rock arm being actuated to cause the pins to
withdraw at proper times by a cam mechanisin equivalent in its function and
operation to the cams carried by the cam wheel. The carrier is further provided,

page_text: at a point opposite to the pins, with another set of pins, that are curved to project
from a rock shaft journaled in the carrier heads, which shaft has at one end a rock
arm, that may be moved into a position to protrude the pins through äpertures in
the blade, or withdraw the same within the carrier. This carrier is furthermore
provided with longitudinal cutting grooves, which will préferably be provided
with cutting blades so arranged that they may be readily removed or rendered
inoperative, and thus convert the carriers into simple conducting rolls or cylinders.
The mechanisms for controlling the action of the devices supported by the carrier
are as follows:-A tripping lever bar, which is branched to properly support
tripping dogs, is arranged so as to be capable of longitudinal or sliding movement,
being for this purpose provided with an elongated guide slot, whereby it may
move on a guide pin projecting from the frame work, and be guided by its forked
end, that embraces a shaft which carries an adjustable cam, in the path of which a
stud or roller projecting from the bar enters. This bar is furthermore provided
with means for securing it in stationary forward or rearward positions, these
means being, in one construction, à screw tapped through the frame and adapted to
be entered into one of two holes with which the bar is provided; and in another
construction, the cam is made the means for securing the proper adjustment. This
cam may be mounted to revolve upon a short shaft projecting from the
framework. Its appropriate timely rotation is produced by means of a toothed
wheel fast on the main shaft which engages a pinion turning freely on said short
shaft, to which wheel the cam is secured. This cain may be adjusted so as to turn
operatively, and thus reciprocate the bar by means of a grooved sleeve of the cam-
carrying pinion, which grooved sleeve is embraced by the arins of a bifurcated
shipping plate, that is moved by an adjusting screw, whereby the stud carried by
the bar may be entered into or withdrawn from the groove in the cam, and the
movements of the bar be accomplished or suspended. The cam is also arranged to
be secured to the shaft so as to revolve therewith by means of a screw, that is
tapped through the hub of the cam and enters the said shaft. It may be secured
to the side frame, and thus held stationary by withdrawing the screw, and so
turning a screw tapped through the side frame, that its end will enter a suitable
hole provided in the side of the cam. When the bar is in its forward position, one
of the dogs will be held so that it will intercept the rock arm and thereby cause
the pins to be drawn within the periphery of the carrier, thus disengaging them
from the paper which is impaled by them, and the other dog will be held in
position to intercept the rock arm of the blade and cause the shaft to be vibrated,
and swing said blade outward and into the space between the rollers.
If it is desired that each sheet produced by the severing of the web into short
lengths through the operation of one or of both sets of cutting devices with which
the carriers are provided, which in the one case will be, say, whole sheets, and in
the other half sheets, it is only necessary to adjust the cam by either of the
described means, so that it will hold the tripping bar in its rearmost position and
stationary. This will remove the dogs so far rearwardly that they will not cause
any of the devices supported by the carrier to become active. In delivering whole
sheets flat, said sheets being only partially severed from the web by the action
of the cutter which has removed portions, the sheets in the form of a web, partially
connected at its lines of ultimate division into sheets, are simply led from the cylinder,
passed between the carriers, and entered into the nip of the rollers. If it is desired
that these sheets shall be entirely severed from the web, the forms may be set
back in the type cylinders, the cutting blade removed, and the cutting blade
thrown into action. The bar will then be adjusted in its forward position, and the
pins be adjusted in their withdrawn or inward position, which removes their rock
arm out of the path of travel occupied by the dog. If it is desired to deliver
half sheets flat, both cutters will be brought into operation, the bar will be
adjusted so as to render the blade inoperative, and both sets of pins in the carrier
will be fixed in their withdrawn position, and both knives have cut away portions.
Each half sheet will then be partially severed from the web and pass between the

page_text: carriers and the rollers. If both cutters operate to entirely sever the web, it will
be necessary, in order to carry the half sheets then produced into the nip of the
rollers, to provide a roller with pins or hooks which may be caused by proper
devices to operate so as to enter the leading end of each sheet, strip it from the
carrier, and, having entered the same into the nip of rollers, be withdrawn. If it
is desired to collect or associate two whole sheets one upon the other and deliver
the same simultaneously through the rollers or pulleys, a cam actuating the bar
will be put into operation, so as to cause said bar to make a forward reciprocation
at each second revolution of the carrier. This will present one dog in position to
operate upon the rock arm and move the swinging blade. The head of the first
sheet will be impaled upon pins, and will be carried around with the carrier, and
receive the second sheet upon it. If, now, it is desired to deliver each full sheet
with a transverse fold certain pins are thrown out of action, and other pins are
thrown into action, and the bar is adjusted in its forward position, so that one dog
will operate these pius, and the other dog. will operate the folding blade at each
revolution of the carrier. Each sheet impaled upon the pins will be carried by
them around to a point opposite the rollers, and the pins will be withdrawn from
the end of the sheet, which will be doubled into the the nip of the rollers, thereby
accomplishing its folding upon a line transverse to the direction of its travel. By
a slight modification of the form of the bar and its cam, and the provision of
additional folding blades, half sheets might be folded in a similar manner.
The secondary sheet manipulating apparatus consists of a structure which
embodies an internal guide and external turners, by the co-action of which a sheet
or web of paper drawn over said guide and through the turners, has its sides
brought together or lapped, so as to impart to the web or sheet the desired
longitudinal-fold. The web or sheet, as it enters upon this guide, is extended flat
widthwise, and its sides are gradually turned or deflected toward each other, and
are finally brought together in passing between said turners. This secondary, or
longitudinal folding mechanism, consists of an internal supporting or turning guide,
preferably formed by bending the forward portion of the main body of a
rectangular metal plate, (of a width equal at least to that of the fabric designed
to be folded), so that the forward edges of its centrally bent sides shall be united
or lie together in a straight line. Such a structure provides bends or internal
turners extending rearward where the sides unite with the body and flare outward
toward the rear end of said body.
The external guides or turners, which may be rollers, pulleys, or fixed surfaces.
supported in spring seated bearings, to permit either single or double sheets to
pass between, are arranged so that their inner surfaces stand parallel with the
meeting edges of the side plates of the guide, and so as to provide between their
inner faces a sufficient space for the passage of the lapped, side sections of the web
or sheet, which are brought together in passing. between said turners.-The rear
edge of the guide will be straight, and may be turned over or secured to a bar, by
which the guide will be attached to the supporting frame, or be extended
rearwardly and be connected with the shaft of a roller or pulley. The external
turners, when made in the pulley or roller form, will preferably be geared together
and properly driven to act as drawing rollers to draw the web or sheet through
the folder. As the meeting forward edges of the inwardly bent sides of the plate.
forming the internal guide stand at right angles to the bottom edges of the sides
of said plate, and the rear edge of the plate is straight in a transverse line, such
disposition will cause the central surface of the plate to stand at an angle of about
forty five degrees with respect to said meeting edges, and the lines of union
between the inwardly bent sides or plates, and the central surface or main body of
the plate, which lines constitute the bends or internal turners, will stand at an
obtuse angle with respect to each other. Hence, as the distance transversely upon
any line drawn parallel with the said meeting forward edges from one edge of the
plate, and to the edge of the plate, must be the same and equal to the length of
the rear or straight edge of the plate, it follows that a sheet or web held

page_text: in contact with said plates, and thus lapped or folded longitudinally, will be
properly distended widthwise; and as the internal guide is in this case
continuous from the point where the fabric passes over its rear edge
through the plates, it also follows that the side sections, which are turned or
deflected centrally to lap upon each other, have their margins supported until the.
same leave the front edges of said plates, when the folding is completed, and hence
that the web at said point of its being so lapped or folded has no slack portion,
whereby its perfect manipulation would be impaired or rupture of its body result.
It will therefore be apparent that, while the meeting forward edges of the sides are
kept at a right angle to the folding line or point of union between the lapped sides
of the fabric, the internal guide may be bent so that its rear edge will be brought
nearer to the lower ends of the meeting forward edges of said plate, and that the.
more it so approaches said forward edge, the greater will be the acuteness of the
angle of the plate with respect to its meeting forward edges, which may continue
until the two stand nearly in the same plane or parallel with each other, the angle
which the bends or turners bear to each other in like manner growing more obtuse.
The raising contra-bending of the plate will of course produce the opposite effect.
These angles of retraction will also vary according to the length given rearwardly
to the plate, and will likewise be changed if the lines of union between the sides
and the central surface of the body of the plate, constituting the bends or turners,
be rounded instead of abrupt. In all cases, however, the same extent of bearing
surface widthwise for the fabric will exist upon any transverse line drawn from
one edge to the other of the side plates and parallel with the meeting edges of the
forward end of the plate, and the fabric will therefore be perfectly sustained in
such modified forms.
It will be apparent from the foregoing description, that the internal parts of the
folder may be divided transversely into a number of narrow plates, so long as a
sufficient number of bearing surfaces be provided to sustain the fabric, especially
its margins, and prevent it from sagging inward or otherwise becoming distorted
from a true course, whereby its perfect folding would be prevented. The internal
guide may likewise be composed of a series of narrow plates or rods or wires, that
start from the bar and extend forward at the proper angles in lines coinciding with
the path of travel of the sheet or web until they terminate at the perpendicular
line of the triangular form they will thus constitute. So, too, the bar, or an
equivalent widthwise support, being provided for the turners, may be contracted to
any extent so long as the fold-forming point is maintained, and in all cases either.
one of the external turners will be sufficient, provided a means for drawing the
sheet through the longitudinal folder is provided. Such construction of longitudinal
turner will operate to perfectly support the fabric, and cause its side sections to be
brought together to form the longitudinal fold. The web will pass directly from
the printing mechanisms between the carriers before referred to, whose mechanisms
then are nonoperative, and, carried between the rollers or pulleys, will enter upon
this longitudinal folder and be distended in the same plane to its fullest width, and
flat, in passing onto the rear edge of the guide or over its bar. In this disposition
of the web, it will be so disposed as to be folded upon a longitudinal line.
onward motion being imparted to the web, its longitudinal folding will be accom-
plished by the direction given it in passing through this longitudinal folder. Thus,
as the web runs in the same direction as the internal guide is disposed, and the
latter is a continuous plate or former, it follows that the web will be supported
longitudinally and transversely, not only during its movement over the internal
guide, while undergoing the folding operation, which supporting is especially
desirable, as it permits the side sections to be positively supported while the
material is being deflected from a common plane, or in passing over the internal
guides or turners, but at the point where the sides of the web come within the
coutrol of the external turners, by which construction of the parts, the perfect run
of the web will be accomplished, and its longitudinal folding performed, without
danger of rupture, buckling, or other injury from distortion.
An

page_text: .
Although this longitudinal folder is described as operating upon a web or
continuous sheet, for convenience of setting forth its operation, it is designed to
have combined with it a means for severing the web into short lengths or sheets.
This may be done by a cutting mechanism operating to divide the web transversely,
and located so as to perform that operation either before the longitudinal folding
is accomplished, or be arranged to sever the web after it has received its longi-
tudinal fold. When the web is to be divided by transverse severance that forms
it into short lengths or sheets through the instrumentality of cutting devices
provided in the carriers, the longitudinal folding apparatus will require to be
provided with a means for conducting the leading edge of each sheet through it,
and, as it is obvious from the flexible character of paper that such conducting
means should be a moving device, tapes are here provided to carry the sheets
smoothly through said longitudinal folder. Four sets of endless outside tapes are
employed, two of which are arranged to pass over the "former" near the point
traveled by the margins of the sheets or material, while the remaining two endless
tapes are centrally arranged. The margin tapes run over pulleys and over the
bends or turners. The central tapes may be omitted entirely, though it is preferable
to retain at least one. A set or sets of under tapes may be arranged to co-act with
these upper tapes if necessary. Where the material operated upon by the longi-
tudinal folder is in the form of a web, a single central tape may be used, and will
serve to carry the leading edge of the web through the apparatus. By this
structure of longitudinal folder and its combination with rotating printing
mechanisms, the two will co-act; so that a freslily printed web of paper, led
directly from the printing mechanisms to this longitudinal folder, can be folded
parallel with the run of the web or sheets composing the same, and such folding
will be accomplished without separating the sheets any distance apart, or providing
a time space between them for the operation of the longitudinal folding mechanism,
and this is also the case whether the web be severed by transverse cuts that divide
it into short lengths or sheets, such severance being either performed before the
longitudinal folding is effected, or after the same is effected. By this construction,
the printing mechanisms may run at the highest possible speed attainable, according
to the condition or strength of the material printed upon, which alone can limit
their speed, for the reason that since there is no separation of the sheets, or distance
provided between succeeding ones, and this longitudinal folder is capable of
performing its function as rapidly as the material can be passed through it, there
can be no limit to the highest rate of speed except the weakness of the material acted
upon. It is desirable to further fold the product emerging from the rollers or
turners, which product may be, first, a full sheet folded longitudinally; second, two
full sheets associated together and folded longitudinally; third, a full sheet folded
transversely and longitudinally; fourth, two full sheets associated together and
folded transversely and longitudinally; fifth, a half sheet folded longitudinally.
A slitter is used to divide the web or sheet in its longitudinal centre, so that the
product emerging from the rollers or turners, in any of the above forins, will be
divided longitudinally, and in the case of full sheets, will be tantamount to
gathering two sheets printed side by side by a lateral transference. It will thus
appear that the size of the product emerging from the rollers or turners may in
length be equal to the length of a full sheet, or that of a half sheet. Conse-
quently, carriers are provided with folding devices, which are arranged to operate
upon both sizes of product, which, for convenience, we will call "full sheets" and
"half sheets"; and as it is further apparent that when the cutting is to be
performed by the carriers, as in case the web emerges from the turners having
been transversely severed into short lengths, it will furthermore be necessary to
provide the carriers with proper cutting devices to sever such web into half sheets
or whole sheets. The folding mechanism operating upon the sheets at this point
may be of any of the well known constructions, whether rotary in operation or con-
structed of turners. Rotary folding mechanisms supported by the carriers are well
adapted for completing the folding desired. These carriers are geared together,

page_text: driven in unison with the other mechanisms by a bevil wheel, on the shaft of the
carrier which wheel is engaged by a similar wheel on a cross shaft, that carries a
toothed wheel conveniently driven.
The carrier is provided with four sockets at equidistant points in its periphery,
in which the removable blocks supporting the tucking or creasing blades and other
blocks carrying cutting blades and sheet carrying pins may be adjusted or removed.
The second carrier is provided with sheet seizing jaws, the vibrating members of
which are upon rock shafts, and actuated by a cam movement in any common
manner.
Suppose the product emerging from the rollers to be a full sheet's length, and it
is desired to impart to it one transverse fold, the cutters and their pins will be
removed from the first carrier, and the block provided with a cutting blade, and
pins will be substituted for the block carrying the creasing folding blade, while the
jaw of the other carrier will be turned inward and rendered inoperative, and
the cutting slot adjusted in place. As such sheet or web emerges from between
the rollers, its leading end will be impaled by the pins, which will carry said
leading end around with the surface of the first carrier. As the central part or
folding line of the sheet overlying the creasing folding blade will be doubled thereby
into the space for it, which then stands open, the double edge thus formed will be
nipped by one jaw, which closes thereon. Thus held by its doubled edge, the sheet
will be carried round, the end of one of its plies being stripped from the pins, and
the two plies laid together to complete the folding. The doubled edge is released
by the opening movement of the jaw, accomplished in time to permit the folded
sheet to be guided out between the tapes. As the cutter and cutting slot come
into operation, they will sever the web, to detach the folded sheet and impale the
leading end of the web upon the pins if the material is in the web form and
entirely uncut. If it is in the web form and partially severed transversely, the
breaking bar might supplant the said cutting blade; if in the sheet form, the pins
will simply engage the leading end of each sheet. If it is desired to impart a
second transverse fold to the sheet, it may be accomplished by throwing into
operation a vibrating folding blade, in which case the block carrying the cutting
slot must be removed and the tapes stretched. As the central part or folding line
of the once folded sheet reaches the rollers, this blade will he turned outward to
double or fold said sheet into the nip of said rollers, which will then deliver it to
the tapes, which will carry it on. If it is desired to fold the product of a half
sheet's length received from the rollers with a single transverse fold, the creasing
folding blade will be put in place of the cutter, and the cutters and pins will be
placed in position. The material from the rollers will be impaled upon the ping
carried around with the first carrier, be folded by the folding blade into the nip of
the jaws, carried by the latter around with the second carrier, the doubled edge
released and guided into the tapes, the forward ply being dragged from the pins.
The next length of material will be impaled upon the pins and folded by the blade
and jaw in like manner. If the material is in the web form, the cutters will sever
it into sheets; or if in the partially severed form, the breaker, taking the place of
said cutter, will separate it into sheets; or if in the sheet form, the pins will
engage it. If it is desired to impart an additional transverse fold to these folded
half sheets, folding blades will be thrown into operation and tapes arranged, the
sheets being released in proper time to permit of the same being folded into the
nip of the folding rollers, through which they will pass in a folded condition.
A supplement web or sheets may be combined with the folded product of this
apparatus in any of its forms. A convenient mode of introducing a supplement is
by feeding such a printed supplement web to the primary carriers or onto the
guide.

WILLIAM CONQUEST of Tudor Street in the City of London Mechanical Engineer
"IMPROVEMENTS IN SHEET DELIVERY APPARATUS FOR PRINTING MACHINES a
communication to me from abroad by Messieurs R. Hoe and Company of the City
and State of New York United States of America.
The improvements embraced in this Invention are especially designed to be used
in combination with web-perfecting printing machines, which machines, in their
present improved state consist of two principal sets of mechanisms viz., the printing
mechanism and the delivery mechanism. The printing mechanisms of such
machines have for many years remained substantially the same, consisting
essentially, of horizontally-arranged printing and impression cylinders capacitated
to run at a high rate of speed and to print the opposite sides of a web or long
length of material, which printing capacity is alone limited by that of the delivery
mechanism, whose function it is to divide the web into short lengths or sheets and
deliver the same properly piled.-A great variety of delivery mechanisms capable
of running at high speed, and thus adapted to be combined with such printing-
machines, have been devised, and during more recent periods these delivery
mechanisms have been so constructed as not only to deliver the sheets open or
flat at high speed but fold them one or more times during such delivery.
The present improvements relate to that class of delivery mechanisms for rotary
printing-machines which deliver the sbeets in a folded condition.
In the accompanying Drawings Fig: 1 Sheet I is a side elevation of so much of
a printing press having the present improvement combined with it as is necessary
to shew the means for driving the principal mechanisms. Fig: 2 Sheet II is a
plan view Fig: 3 an end elevation and Fig: 4 Sheet I a longitudinal sectional

It is well known to those skilled in the art of printing as carried out in rotary

page_text: "
web-printing machines" in which the web is cut into sheets after it is printed,
that the printing surface covers the circumferential extent of the cylinder, and that
therefore any change in the size of the printing-surface can only be made in the
direction of the length of the cylinder.
Now, in producing newspapers and similar periodicals, for which the web-
printing machine is largely used, the direction in which their first fold should be
given depends upon several conditions; first, whether the sheets are printed from
columns running around or parallel with the axis of the printing-cylinder; second,
whether the sheet be a four-page paper or an eight-page paper; third, also,
whether the eight-page sheet be folded intact or composed of two separate four-
page sheets.
From this it will be seen that the first fold in some cases should be a
longitudinal one and in other cases a transverse one; and these improvements
enable one and the same mechanism to fold Firstly. first longitudinally, the
subsequent folds being preferably at a right angle thereto and also to each other,
or secondly, first transversely, and the subsequent folds at a right angle thereto and
to each other. Two sheets may be collected one upon the other, and said collecte 1
sheets, or signature, may be folded, firstly first longitudinally, the subsequent folds
being at a right angle thereto and to each other, or secondly, first transversely, the
subsequent folds being at a right angle thereto and to each other. If it should be
desired that at any time the number or width of columns should be increased or
diminished then the columns must be parallel with the run of the paper and
around the type-cylinder; but if on the contrary, it should be desired to lengthen
or shorten the columns then they must lie transverse to the run of the paper and.
parallel with the axis of the type-cylinder.
The same printing-machine may sometimes be required to print a paper from a
form the columns of which run around a cylinder, or from a form the columns of
which run lengthwise of the cylinder, and it may be desirable in the one case to
make the first fold in one direction, and in the other case to make the first fold
in the opposite direction.
In this Invention, as illustrated and combined with a printing-machine, the first
folding mechanism is one that gives the sheets a transverse fold, and the next.
folding mechanism one that gives the sheets a longitudinal fold: but the transverse
folding device is so arranged that it may at pleasure be thrown out of operation
and become simply a carrier. Thus the first fold the sheet will receive may be
either a transverse or a longitudinal one.
In order to a ready understanding of the invention in all of its details I will first
describe the mechanisms singly.
The printing mechanism shown serves to illustrate the combination of the
improvements with a well-known form of such mechanism, said improvements
being adapted to any construction of rotary printing mechanism. This mechanism
comprises type-cylinders A B and impression-cylinders C. D. (see particularly
Figures 9 and 10) all of which are journaled in a suitable frame-work and geared
together by means of toothed wheels, as 101. 103. 102. 104. so as to revolve in
unison, one impression-cylinder, as D being of large diameter, to operate as a set-
off cylinder, as is common. The type-cylinders A. B may be of a diameter equal to
two lengths of the product to be printed, twice that size, or any multiple thereof,
as may be desired, and be of a length to print one or more products side by side, aч
is common, if desired. For the purpose of this specification I have shown the
impression-cylinder B of one size in Fig. 9 and 11 and of double that size in
Figures 13 and 15. The usual blanketing of the impression-cylinders and the
common fittings of the type-cylinders, whereby they are adapted to hold forms of
type or plates, will be used and any suitable inking apparatus.
The paper having thus been printed is passed to the primary folding mechanism,
or that one which is capacitated to fold the paper transverse to its direction of
travel. This mechanisin consists of a rotating carrier E Fig: 1 (preferably a
cylinder) the periphery or shell of which is perforated to accommodate the
protrusion of the various mechanisms it carries, the shaft 51 of which is journaled.)

page_text: in the frame-work and provided with a driving toothed wheel 105, meshing with
the wheel 104 whereby said carrier is caused to rotate with the same surface-speed
as that of the printing mechanism, though in Figures 1 to 8 the connecting-gearing is
marked 105. 106. 102. In the construction of the primary folding mechanism, which
will preferably be used in practice because of the simplicity and compactness of its
parts and is shown in figures 1. to 8 the carrier E is provided at one point of its
periphery with a folding-blade 9. mounted to turn with a shaft 31. that is journaled
in the carrier-heads, said shaft supporting oppositely extended folding-blades con-
stituting a double folding-blade such as is now well known. This double folding-
blade is however modified in construction so that one of its members or blades may
be readily removed and replaced by any common means. Its shaft 31 is extended
through one head of the carrier and provided with two opposed rock arms. 10. one
of which, during each revolution of the carrier E, engages a guide-way or cam-path
formed by a flying cam 12 and a stationary cam 13, that is fast to the frame-work.
This flying cam 12 is mounted upon the face of a toothed wheel 45, that is carried
by a short stud journaled in the frame-work (see Fig: 2) This wheel, and conse-
quently the cam, is rotated in proper time by means of a toothed wheel or driving-
pinion 46, fast upon the shaft 51. of the carrier E said flying cam being thereby
rotated so as to cooperate with the stationary cam in directing the rock-arm of the
folding-blade through a cam-groove that will cause the blade-shaft to make a semi-
rotation and one blade to be thereby protruded from and withdrawn into the
carrier, during which movement it enters the space between the rollers 32. 33 and
accomplishes the folding operation. Although the blade-shaft makes a semi-rotation
at each revolution of the carrier E such rotation becomes an idle or inoperative one
when one blade is removed or the folder has a single folding-blade. At a point
opposite to that in which the folding-blade is mounted the carrier E is
provided with a shaft from which co-operative fingers 5 project outwardly. These
fingers are adapted to lie closely upon or in the periphery of the carrier
and their carrying-shaft 30, projecting through one head of the carrier,
is provided with a rock-arm, 11. one end of which bears upon a spring 47. which
acts to close said fingers down into the periphery of the carrier E. while its other
end carrying the stud or friction-roller, protrudes, so as to be engaged at proper
times by means of the cams 1 and 2 secured to the face of the toothed wheel 60.
which is provided with means for fixing it in the side frame in one of two positions
as indicated by its adjustment in Figures 5 and 6 or 7 and 8. This wheel 60. in
either position of its adjustment, remains geared with its driving-pinion 59. which
is fast upon the shaft of the carrier E. One of the cams-say 2-with which
this wheel is provided is constructed so that it may be attached to said wheel and
be readily removed therefrom by any common means, for a purpose that will soon
be explained. It is obvious that in either position of its adjustment this cam-
wheel 60 will rotate and bring its cam 1 or 2 into position to intercept the
rock-arm 11. and thus pressing it outwardly, cause the fingers 5 to be raised from
the periphery of the carrier E and this movement of them will be produced when
the fingers are passing the rollers 32. 33 or a point opposite thereto, at each
revolution of the carrier E or each second revolution thereof according to the
position in which the cam wheel 60 is adjusted to the franie and according as it
carries one or both of the cams 1. and 2 all of which will be better understood in
the description of the operation yet to be made. This carrier is also provided with
pins 6. which protrude through holes in its surface, and through holes in fingers 5.
provided therefor, which pins 6. are secured to a shaft 58. that is mounted in the
heads of said carrier E so that when the fingers 5. operate to strip the paper there-
from they will be slightly rocked in the direction of the outward movement of the
fingers 5. and thus remove the paper from said pins without enlarging the
perforations or tearing it-This carrier E is constructed so as to form one of a pair
of cutting-cylinders it being for that purpose provided with a cutting-edge or
knife 7. which cooperates with a projection or breaker or blade 28. carried by a
companion carrier F. that is mounted in the frame below the carrier E, and geared

page_text: thereto by the toothed wheel 106. so as to run in unison therewith. This carrier F
is also provided with recesses to receive the points of the pins 6.
The rollers 32. 33. which aid in the folding operation, are suitably journaled
in the frame-work, and will be provided or not, as necessity may require, with
gear-wheels causing them to run in unison and with a surface-speed equal to or in
some cases faster than that of the carrier E which they may obtain by proper
gearing connecting with the toothed wheel 105
A set of guides 48. are mounted upon a shaft 49. by means of which they may
be adjusted to coact with fingers 5. and guide sheets from the surface of the
carrier E directly into the nip of the rollers 32. 33 their ends being properly
curved for this purpose and their shaft provided with a rock-arm and holding
screw 74 The guides 48 as combined with the carrier E and rollers 32. 33 are
introduced herein for the purpose of illustrating other improvements, and are not
claimed. Supposing said guides to be adjusted into their guiding position, as in
Fig: 5 and the cam-wheel 60. to have its shaft secured in the frame-work as in Fig: 2
so as to maintain said wheel during its rotation at the point best shewn in Fig: 5
and the two cams 1 and 2 carried by said wheel to be adjusted in their working
position, and the flying cam 12. carried by the toothed wheel 45. to be removed, so as
to render the said folding-blade entirely inoperative the operation will be as follows,
The web of paper is passed through the printing mechanism and printed on both
sides in the usual manner. In its properly printed condition its leading end
is stretched from the last type and impression cylinders of the printing machine
and impaled upon the pins 6. of the carrier E and by them carried onward as in
Fig: 5. When however, said pins are brought near the roller 32. the cain 1 on
the wheel 60 will by the rotation of said wheel, have reached a position to be
engaged by the rock-arm 11 of the fingers 5. thereby rocking said fingers outward
stripping the edge of the paper from off the pins, and giving it a direction that
will cause it to enter underneath the guides 48. and be directed by them into the
nip of the rollers 32. 33. through which it will be delivered. It may then be, for
some purposes, carried off by the tapes shown, or be otherwise manipulated, as will
be hereinafter explained.-As the carriers E F continue to revolve, the rock arm 11.
will be carried out of contact with the cam on wheel 60. and the spring 47. will
then rock said fingers back to their normal position, the folding blade will pass
the rollers 32. 33 inoperatively, and the projection 28. of the carrier F will press
the web past the knife 7. in the carrier E. and thereby sever it laterally into a
short length or sheet, the end of the web from which said sheet is detached having
been impaled upon the pins 6. in being laid onto the carrier E.-When, however
the end of the web reaches the proper point in its approach to the rollers 32. 33.
these fingers 5. will be again operated (but at this time by the cam 2. on wheel 60)
to direct the leading end of the web under the guides 48. and thence between the
rollers 32. 33. whence it will be carried outwardly, as before explained. Thus each
printed sheet, which may then constitute a whole product, will simply be severed
from the web by the mechanisms of the carriers E and F and conducted outward
while extended their full length or flat. In this operation, although the gear
wheel 60. carries two cams 1 and 2. it is apparent that the wheel 60. or the cam 1.
might be secured in a fixed position. so that one can would cause the movement
of the fingers each time that they pass the rollers 32. 33. In consequence of the
other operations carried on by this mechanisın, in which it is necessary that the
fingers 5. be operated at only every second revolution of the cam E the actuating
cams 1. 2 are secured to the wheel 60. which is twice the size of its driver, said
driver being a tooth-wheel 59. secured to the shaft of carrier E. Therefore the
carrier E will make two revolutions while the wheel 60. makes but one, thus
presenting the same cam as 1. in acting position at every alternate revolution of
the carrier E.
If, now, it be desired to change the arrangement of the printing-plates carried
by the type-cylinders and so place them that each sheet printed thereby will be
the component half of a complete product, in which case it would be desirable to

page_text: bring two successive sheets one upon the other, or if, for any other reason, it is
desirable to collect two sheets one upon the other, it is but necessary to remove
one of the cams as 2. from the wheel 60. when the apparatus will operate as
follows. When the first of this part of sheets, whose forward end is carried by
the pins 6. approaches the point occupied by the rollers 32. 33 that side of the
wheel 60. whence cam 2. was removed is then presented toward said rollers, and
consequently permits the rock-arm of the fingers to pass that point without being
moved. The pins consequently retain their bold upon said sheet and carry it
forward in the relative movement of the carrier E.-It thus carries the first sheet
entirely around with the carrier, and causes the same to receive the second sheet
upon it, the two then being impaled on the pins 6. and the cutting devices of the
carriers E and F severing this second sheet in like manner as it did the first.-
When the forward edges of these combined sheets held by the pins 6. approach the
rollers 32, 33 the wheel 60. will then have made the last half of its revolution,
and will present its cam 1. in proper position to engage the rock arm 11 of the
fingers 5 and vibrate the same outwardly, thereby stripping the ends of the two
combined sheets from the pins and entering them simultaneously into the bite of
the rollers 32. 33. from whence the sheets will pass out for subsequent treatment
as before described.
From this description it will appear that the carrier E when provided with pins
and mechanisms governing the control of the paper, together with the conductors 48.
will constitute a gathering or controlling mechanism.
If, now, it is desired to fold the sheets transversely, either singly or in gathered
pairs the same may be accomplished by bringing into action the folding-blade 9.
which may be done by simply restoring its flying or actuating cam 12. into its
operative position, as shewn in Figures 1 and 2 the conductors 48. then being
raised out of action, and the position of the cam wheel 60. (now provided with both
its cams 1, 2) will be changed to that shewn in Figures 7 and 8 its carrying-stud
being secured to the frame, in the hole shown by dotted lines in Fig: 2 where it
will rotate, as before described. In this arrangement of the parts the cams 1. and 2.
upon the wheel 60. will so operate that at each revolution of the carrier E the
fingers 5. will be vibrated outwardly to release the end of the sheet in passing the
point nearly opposite to the rollers 32. 33. thus carrying each sheet onward far
enough to present its middle portion or that part which is to receive the fold,
properly before said rollers. The folding-blade will make a semi-revolution at each
rotation of the carrier E, and one of its blades 9. be protruded between the
rollers 32. 33. at each rotation of said carrier. It will therefore be understood that
each sheet engaged by the pins will be carried past the rollers 32. 33. and be folded
by the operation of the folding blade into the nip of said rollers the fingers being
vibrated at the proper time to release the forward end of said sheet to enable it to
pass between the rollers 32. 33 in a once folded condition which fold will be
transverse to the run of the web, and each folded sheet may then be delivered by
the tapes shewn for subsequent operations.
If it is desired to collect two sheets one upon the other and to fold the same
simultaneously with a transverse fold, one cam, as 1. is removed from the cam-
wheel 60. and one blade from the folding blade, as is shewn in Fig: 8 The first
sheet will be carried by the pins around with the carrier E the cam-wheel 60 then
so rotating as to admit the rock-arm of said fingers to pass by it without being
acted upon and the folding-blade shaft making that half of its revolution which
turns the single blade it then carries inwardly, as the rollers 32. 33. are passed.-
The second sheet is received upon the first, as heretofore explained with reference
to Fig: 6, the web is severed, and the two sheets impaled upon the pins 6. are carried
onward past the rollers 32. 33. and when the middle portion or folding-point of
such collected sheets arrives before said rollers, that revolution of the folding-blade
shaft is made, which protrudes the single folding-blade outwardly whereby the two
sheets are simultaneously doubled into the nip of the rollers 32. 33, the wheel 60
simultaneously bringing into operation its cam 2. and causing the vibration of the

page_text: fingers to release the leading ends of the two sheets, so that the said sheets may be
free to pass through the rollers 32. 33. from whence they may be delivered for sub-
sequent manipulation. It will also be understood that when it is desired, the pins 6.
may be turned inwardly and rendered inoperative, and also that the projection on
carrier F may be removed when the cylinders E F would be empty carriers.
A modified construction of devices for effecting these same operations is shown in
the primary apparatus, more particularly by Figures 9 to 20, which will now be
explained In this arrangement the carrier E is provided with a single
folding-blade 9. that projects from the shaft 31. which shaft is now adapted to be
vibrated, so as to swing the folding-blade, such movement being imparted by a single
rock-arm 10. whereby the said blade is protruded at proper times beyond the
periphery of the carrier for coaction with the rollers 32. 33, which are here shewn
in form of pulleys and as provided with pinions 61. 62. whereby they are driven
by the pinion 61. from the wheel 105.-The longitudinal row of pins 6. is arranged
to be automatically protruded beyond and drawn within the periphery of the
carrier or to be fixed in either their protruded or withdrawn positions.-For
this purpose they may be secured to a plate or bar, 34 as in Fig: 11 arranged to
slide in ways provided within the carrier, which plate or bar is provided with a
rack or racks, with which a pinion or pinions 35. fixed upon a shaft. which may be
the shaft 30. engage.-In this structure a spring as 47 or a spiral spring, will be
arranged to so rock the shaft 30. as to cause it to protrude the pins, its rock
arm 11 being actuated to cause the pins to withdraw at proper times by a cam
mechanism equivalent in its function and operation to the cams carried by the
cam-wheel 60. The carrier E is further provided at a point opposite to the pins 6.
with another set of pins as 17. (see Figures 13 and 15) that are curved to project
from a rock-shaft 93. journaled in the carrier-heads, which shaft has at one end a
rock arm 43. that may be moved into a position to protrude the pins through
apertures in the blade 9. or withdraw the sume within the carrier. These pins may
be secured in either of such positions by means of spring-seated pins. as 38. pro-
jecting through a hole in the carrier-head and engaging a hole in said rock arm 43
(See detached view. Fig: 13ª Sheet VII) The pins 6. may be maintained in their
withdrawn or protruded position by like means, and both or either sets of these
pins may be secured in either of their positions by any other means. This carrier E
is furthermore provided at points near the projecting points of the pins 6. and that
of the blade 9. with longitudinal cutting-grooves 7 and 12. which will preferably
be provided with cutting-blades: or one wall of the groove 12. may be formed by
the edge of the shell of the carrier and the other wall by the edge of the blade 9.
with which cutting-blades 28 and 29 supported by the carrier F co-operate. The
cutting blade 28. is arranged in any convenient manner so that it may be removed
bodily from the carrier which blade, when in place, however, cooperates during
each turn of the carrier with the cutting slot or blade 7.-This removability renders
it convenient to provide the carrier F with a blade having a cutting-edge that will
make a complete severance, or with one having portions of its cutting-edge
removed. The cutting blade 29. has portions of its edge removed, and is arranged
to be carried constantly by the carrier, but constructed so as to be thrown into or
out of action, as may be required. Thus it is mounted so as to slide in ways
provided within the carrier and has one or more racks that are engaged by a
pinion or pinions 39. (see fig: 15) fast upon a shaft journaled in the heads of the
carrier, and provided at one end with a rock-arm 40. by the movements of which
said rock-arm this cutting blade may be protruded from or withdrawn within the
periphery of said carrier as may be required.-It may be secured in either of these
positions by means of a pin or screw passed through a hole in the rock-arm and
entered into holes as 41. in the carrier-head or it may be arranged to be secured in
manner similar to that shewn and described for securing the pins of the carrier E.
Its two positions are shewn in Figures 11 and 13.-Any other cutting mechanism
may however be used, and all of the cutting instrumentalities should be constructed

page_text: so that they may be removed or rendered inoperative, and thus convert the carriers
E and F into simple conducting rolls or cylinders.
The mechanisms for controlling the action of the devices supported by the
carrier E are as follows. A tripping lever bar 50 which is branched to properly
support tripping-dogs 22. 23. is arranged so as to be capable of longitudinal or
sliding movement, being for this purpose provided with an elongated guide-slot 25.
whereby it may move on a guide-pin 26. projecting from the frame-work, and be
guided by its forked end, that embraces a shaft which carries an adjustable
cam 99. in the path 19 of which a stud or roller 20. projecting from the bar 50:
enters. This bar 50. is furthermore provided with means for securing it in
stationary forward or rearward positions, the same being in one construction (see
Figures 11 and 12) a screw 69. tapped through the frame and adapted to be
entered into one of the holes 70. 71. with which the bar is provided, and in
another construction the cam 99. is made the means for securing the proper
adjustment, as will presently appear This cam may be mounted to revolve upon
the shaft 100. of the cylinder D or upon a short shaft 80. projecting from the
frame work. In the latter case its appropriate timely rotation is produced by
means of a toothed wheel 107 fast on the shaft 100 which engages a pinion 63.
turning freely, on said short shaft 80. to which wheel the cam is secured This
cam may be adjusted so as to turn operatively, and thus reciprocate the bar 50. as
in Figures 11 and 12 where its movement is shewn to be accomplished by means
of the grooved sleeve 3. of the cam carrying pinion 63. which grooved sleeve is
embraced by the arms of a bifurcated shipping-plate. 36, that is moved by an
adjusting screw 37. to carry said cam and pinion laterally, whereby the stud 20.
carried by the bar 50. may be entered into or withdrawn from the groove in the
cam and the movements of the bar be accomplished or suspended. In figures 13
to 15 the cam is arranged to be secured to the shaft 100 so as to revolve therewith
by means of a screw 81 that is tapped through the hub of, the cam and enters the
said shaft It may be secured to the side frame and thus held stationary by
withdrawing the screw 81. and so turning a screw 82. tapped through the side
frame that its end will enter a suitable one of the holes 91. provided in the side of
the cam.
When the bar 50. is in its forward position its dog 22. will be held so
that it will intercept the rock-arm 11. and thereby cause the pins 6. to be drawn
within the periphery of the carrier E, thus disengaging them from the paper
which is impaled by them, and the dog 23. will be held in position to intercept
the rock-arm 10. of the blade 9 and cause the shaft 31. to be vibrated and swing
said blade 9. outward and into the space between the rollers 32. 33. as in Fig: 15.
If it is desired to hold the rear end of a severed sheet or sheets carried by the
cylinder E when the same is operating to collect sheets, the forward ends of which
sheet or sheets are held as before described, a set of pins, as 57 (see Figures 5 to 8)
located in front of the cutting member of said cylinder, would, when the sheet is
severed penetrate and hold the same until they are stripped therefrom by the action
of the rollers 32. 33.
The operation of these modified structures of the primary apparatus is as
follows: If it is desired that each sheet produced by the severing of the web into
short lengths through the operation of one or of both sets of cutting devices with
which the carriers E and F are provided, which in the one case will be, say whole
sheets and in the other half sheets, it is only necessary to adjust the cam 99 by
either of the described means so that it will hold the tripping-bar 50 in its
rearmost position and stationary. This will remove the dogs 22. 23. so far
rearwardly that they will not cause any of the devices supported by the carrier E
to become active In delivering whole sheets flat, said sheets being only partially
severed from the web by the action of the cutter 28. which has removed
portions, the sheets, in the form of a web partially connected at its lines
of ultimate division into sheets, is simply led from the cylinder D, passed
between the carriers E and F and entered into the nip of the rollers 32. 33.

page_text: It is desired that these sheets shall be entirely severed from the web, the
forms may be set back in the type-cylinders the cutting-blade 28 removed and
the cutting blade 29 thrown into action. The bar 50 will then be adjusted in its
forward position, and the pin 6. be adjusted in their withdrawn or inward position,
which removes their rock-arm 11 out of the path of travel occupied by the dog 22.
-The head of each sheet will then be impaled upon the pins 17. and, as it is
passing the point occupied by the roller or pulley 32 the rock-arm of the blade 9.
will engage the dog 23, and cause said blade to swing outward to direct the
leading end of said sheet into the nip of the rollers 32. 33 as in Fig 15.-If it is
desired to deliver half sheets flat both cutters 28. 29 will be brought into operation,
the bar 50. will be adjusted so as to render the blade 9. inoperative, and both sets
of pins in the carrier E will be fixed in their withdrawn position, and both knives
28. 29 have cut-away portions. Each half sheet will then be partially severed
from the web and pass between carriers E F and the rollers 32. 33. "If.both
cutters 28. 29 operate to entirely sever the web, it will be necessary in order to
carry the half-sheets then produced into the nip of the rollers 32. 33 to provide
the roller 32, with pins or hooks 95. which may be caused by proper devices to
operate so as to enter the leading end of each sheet, strip it from the carrier E and
having entered the same into the nip of rollers 32. 33. be withdrawn. If it is
desired to collect or associate two whole sheets one upon the other and deliver the
same simultaneously through the rollers or pulleys 32. 33. the cam 99. actuating
the bar 50. will be put into operation, so as to cause said bar to make a forward
reciprocation at each second revolution of -the carrier E.-This will present the
dog 23. in position to operate upon the rock-arm 10. and move the swinging
blade 9. The blade 28 being removed, the pins 6. secured in their withdrawn
position and the blade 29. thrown into action, the head of the first sheet will be
impaled upon the pins 17. and will be carried around with the carrier E receive
the second sheet upon it, the blade 29. cutting the web into sheets, which sheets
will when their leading ends arrive at the roller 32. be simultaneously stripped
from the pins 17. by the action of the blade 9. which at this time is operated by
the contact of its rock arm 10. with the dog 23. which is moved forward in proper
position for this purpose, the time being that of the forward movement of the
bar 50. In this operation, of course, the pins 95. will be out of action. If, now,
it is desired to deliver each full sheet with a transverse fold, the pins 17. are
thrown out of action the pins 6. are thrown into action, and the blade 28. is
thrown into action, and the bar 50. is adjusted in its forward position so that its
dog 22 will operate the pins 6 and its dog 23. will operate the folding blade 9. at
each revolution of the carrier E.-Each sheet impaled upon the pins 6. will be
carried by them around to a point opposite the rollers 32. 33 at which time the
dog 22. will operate to withdraw the pins from the end of the sheet, and the
dog 23. will operate to swing the folding blade 9. outward between the rollers
32: 33 thus carrying the sheet with it and doubling it into the nip of the rollers
32. 33. thereby accomplishing its folding upon a line-transverse to the direction
of its travel. A's this sheet is passing between the rollers 32. 33. and the web
between the carriers E and F the cutter 28 operates to sever the sheet undergoing
the folding operation and leave the end of the web which is to form the succeeding
sheet impaled upon the pins 6.-By a slight modification of the form of the bar 50
and its cam and the provision of additional folding blades half sheets might be
folded in a similar manner.
In the folding operation the blade 9. is prevented from dragging over the
periphery of the roller 33. or the paper thereon, in making its retiring movement,
by a guard of common forin against which the arm 10 of the folding blade 9.
presses, and as soon as clear therefrom is quickly redirected by the action of the
spring to its former position in the carrier, the dog 23. simultaneously making its
retiring movement.
.The sheets either extended flat or folded transversely may be directed from the
rollers 32. 33. to any form of apparatus either for further folding the same or

page_text: for piling them or be manipulated by any longitudinal folder composed of
turners.
The secondary sheet manipulating apparatus as illustrated herein consists of a
structure which embodies an internal guide and external turners, by the coaction
of which a sheet or web of paper drawn over said guide and through the turners
has its sides brought together or lapped so as to impart to the web or sheet the
desired longitudinal fold.-The web or sheet as it enters upon this guide is
extended flat width wise, and its sides are gradually turned or deffected toward
each other, and are finally brought together in passing between said turners.-
This secondary or longitudinal folding mechanism consists of an internal supporting
or turning guide G preferably formed by bending the forward portion of the main
body of a rectangular metal plate (of a width equal at least to that of the fabric
designed to be folded) so that the forward edges of its centrally-bent sides 14. 18
shall be united or lie together in a straight line. Such a structure provides
bends or internal turners 15. 16 extending rearward from the point t. where the
sides unite with the body and flare outward toward the rear end of said body.
The external guides or turners 55. 56 which may be rollers, pulleys, or fixed
surfaces supported in spring-seated bearings, to permit either single or double
sheets to pass between, are arranged so that their inner surfaces stand parallel
with the meeting edges of the side plates of the guide G and so as to provide
between their inner faces a sufficient space for the passage of the lapped side
sections of the web or sheet, which are brought together in passing between said
turners. The rear edge of the guide G will be straight, and may be turned over
or secured to a bar 21. by which the guide will be attached to the supporting
frame, or be extended rearwardly and be connected with the shaft of the roller or
pulleys 32. The external turners 55. 56 when made in the pulley or roller form,
will preferably be geared together and properly driven to act as drawing-rollers
to draw the web or sheet through the folder.-As the meeting forward edges of
the inwardly-bent sides of the plate forming the internal guide stand at right
angles to the bottom edges of the sides of said plate, and the rear edge of the plate
is straight in a transverse line, such disposition will cause the central surface of
the plate to stand at an angle of about fourty five degrees with respect to said
meeting edges, and the lines of union between the inwardly-bent sides or plates
14. 18. and the central surface or main body of the plate, which lines constitute
the bends or internal turners 15. 16. will stand at an obtuse angle with respect to
each other. Hence as the distance transversely upon any line drawn parallel with
the said meeting forward edges from one edge of the side 14. over the plate and
to the edge of the side 18. must be the same and equal to the length of the rear or
straight edge of the plate, it follows that a sheet or web held in contact with said
plates, and thus lapped or folded longitudinally, will be properly distended
widthwise; and as the internal guide is in this case continuous from the point
where the fabric passes over its rear edge through the plates 14. 18 it also follows
that the side sections which are turned or deflected centrally to lap upon each
other, have their margins supported until the same leave the front edges of said
plates, when the folding is completed and hence that the web at said point of its
being so lapped or folded has no slack portion whereby its perfect manipulation
would be impaired or rupture of its body result. It will therefore be apparent
that while the meeting forward edges of the sides 14. 18. are kept at a right
angle to the folding-line or point of union between the lapped sides of the
fabric, the internal guide may be bent so that its rear edge will be brought nearer
to the lower ends of the meeting forward edges of said plate and that the more it
so approaches said forward edge the greater will be the acuteness of the angle of
the plate with respect to its meeting forward edges, which may continue until the
two stand nearly in the same plane or parallel with each other, the angle which the
bends or turners 15, 16 bear to each other in like manner growing more obtuse.-
The raising contra bending of the plate will of course produce the opposite effect.―
These angles of retraction will also vary according to the length given rearwardly

page_text: to the plate and will likewise be changed if the lines of union between the
sides 14, 18 and the central surface of the body of the plate constituting the bends
or turners 15, 16 be rounded instead of abrupt.-In all cases however the same
extent of bearing surface widthwise for the fabric will exist upon any transverse
line drawn from one edge to the other of the side plates and parallel with the
meeting edges of the forward end of the plate and the fabric will therefore be
perfectly sustained in such modified forms.
It will be apparent from the foregoing description that the internal parts of the
folder may be divided transversely into a number of narrow plates so long as a
sufficient number of bearing surfaces be provided to sustain the fabric especially
its margins and prevent it from sagging inward or otherwise becoming distorted
from a true course whereby its perfect folding would be prevented.-The internal
guide may likewise be composed of a series of narrow plates or rods or wires that
start from the bar 21 and extend forward at the proper angles in lines coinciding
with the path of travel of the sheet or web until they terminate at the perpendicular
line of the triangular form they will thus constitute.-So too the bar 21 or an
equivalent width wise support being provided for the turners 15, 16 may be
contracted to any extent so long as the fold-forming point t is maintained and in
all cases either one of the external turners will be sufficient provided a means for
drawing the sheet through the longitudinal folder is provided.-Such constructions
of the longitudinal turner are within the present Invention and will operate to
perfectly support the fabric and cause its side sections to be brought together to
form the longitudinal fold. Assuming the tapes which this longitudinal folder is
shown as provided with in the drawings to be dispensed with the operation will be
as follows: The web either in the form of a continuous fabric or one having lines
of transverse division partially severed in it but maintaining its character of a
continuous web will pass directly from the printing mechanisms between the
carriers E and F whose mechanisms then are non-operative and carried between
the rollers or pulleys 32, 33 will enter upon this longitudinal folder and be distended
in the same plane to its fullest width and flat in passing onto the rear edge of the
guide G or over its bar 21.-In passing over the body of the guide G its side
sections will be directed over the turners 15, 16 and droop against the side
plates 14, 18 of said guide the sides of said web being thus gradually brought
together and their leading edges will be lapped so as to meet and enter between
the external turners 55, 56. In this disposition of the web it will be so disposed
as to be folded upon a longitudinal line the doubling or folding of which is at the
point t. An onward motion being imparted to the web, its longitudinal folding
will be accomplished by the direction given it in passing through this longitudinal
folder. Thus as the web runs in the same direction as the internal guide is
disposed and the latter is a continuous plate or former it follows that the web will
be supported longitudinally and transversely not only during its movement over the
internal guide G while undergoing the folding operation, which supporting, is
especially desirable, as it permits the side sections to be positively supported while
the material is being deflected from a common plane or in passing over the
internal guides or turuers 15, 16 but at the point where the sides of the web come
within the control of the external turners 55, 56 by which construction of the
parts the perfect run of the web will be accomplished and its longitudinal folding
performed without danger of rupture buckling or other injury from distortion.
The side plates 14, 18 may be omitted if desired and the greater part of the body
plate of the external guide may also be removed the turners 15, 16 and 55, 56 in
connection with the bar 21 or a guiding roller as 32 being sufficient to perform the
longitudinal folding when as in this case the web is continuous.—Although I have
described this longitudinal folder as operating upon a web or continuous sheet for
convenience of setting forth its operation it is designed to have combined with
it a means for severing the web into short lengths or sheets.-This may be done by
a cutting mechanism operating to divide the web transversely and located so as
to perform that operation either before the longitudinal folding is accomplished as

page_text: by the cutting devices of the carriers E F or be arranged to sever the web after it
has received its longitudinal fold as by the devices of the carriers H I yet to be
described, but where the cutting devices of the carriers E F operate to partially
sever a web, such a web when longitudinally folded may be divided into sheets by
the action of the carriers H I when the latter are made to travel slightly faster
than the printing mechanisms and thus break the web upon its partially divided
lines as the tail of each sheet emerges from between the turners or rollers 55, 56
in the manner common in web printing machines.-When however the web is to
be divided by transverse severance that forms it into short lengths or sheets
through the instrumentality of the cutting device provided in the carriers E F the
longitudinal folding apparatus will require to be provided with a means for
conducting the leading edge of each sheet through it and as it is obvious from the
flexible character of the paper that such conducting means should be a moving
device, tapes are here provided to carry the sheets smoothly through said longi-
tudinal folder. One set of tapes for this purpose (illustrated more particularly by
Figures 9 to 11, 13. 15, 19 and 20) will now be described. As shown four sets of
endless outside tapes are employed two of which endless tapes a c are arranged to
pass over the "former" G near the point travelled by the margins of the sheets or
material while the remaining two endless tapes io are centrally arranged.-The
margin tapes a e run from the pulley or roller 33.-Thence they pass onto the base
or rear surface of the guide G, follow near its margin edges, pass over the bends or
turners 15, 16, follow near the margin edges of the side plates 14, 18 and return
around pulleys or the inner ends of the rollers 55, 56, the tapes a returning over
the inner ends of a roller 88 and a roller 84 or bending pulleys substituted
therefor, and a bending pulley 85 to the pulley or roller 33, while the tape o
returns in like manner to the said roller or pulley over the inner end of a roller 90
and a roller 86 or bending pulleys substituted therefor and a bending pulley 87.-
The central tapes io run from the roller or pulley 33 thence pass onto the base or
rear surface of the guide G, follow near its central line, pass over the bends or
turners 15, 16 near the folding point t and return over the ends of the outer
rollers 55, 56 or pulleys substituted therefor, the tape i thence passing rearwardly
over the outer end of the roller 88 and the roller 84 or a pulley substituted
therefor, thence over the bending pulley 89 to the roller or pulley 33, while the
tape o returns rearwardly over the outer end of the roller 90 and the roller 86 or
pulleys substituted therefor and a bending pulley 91.-The central tapes may be
omitted entirely though it is preferable to retain at least one say the tape i
as is shown in Figures 17, 21, 22.-It will run from the roller 33 or a pulley
substituted therefor, passing onto the central portion of the former G and extending
quite near its folding point t where it returns over a bending pulley to the roller
or pulley 33. A set or sets of under tapes might of course be arranged to co-act
with these upper tapes but the same are unnecessary especially when the continuous
or plate form of folder is used. Where the material operated upon by the
longitudinal folder is in the form of a web, a single central tape may be used and
will serve to carry the leading edge of the web through the apparatus.-By this
structure of longitudinal folder and its combination with rotating printing
mechanisms, the two will coact so that a freshly printed web of paper led directly
from the printing mechanisms to this longitudinal folder can be folded parallel with
the run of the web or sheets composing the same and such folding will be
accomplished without separating the sheets any distance apart or providing a time
space between them for the operation of the longitudinal folding mechanism and
this is also the case whether the web be severed by transverse cuts that divide it
into short lengths or sheets performed either before the longitudinal folding
is effected or after the same is effected.-By this construction the printing
mechanisms may run at the highest possible speed attainable, according to
the condition or strength of the material printed upon, which alone can
limit their speed, for the reason that since there is no separation of the
sheets, or distance provided between succeeding ones, and this longitudinal

page_text: folder is capable of performing its function as rapidly as the material can be passed
through it, there can be no limit to the highest rate of speed, except the weakness
of the material acted upon.-It is desirable to further fold the product emerging
from the rollers or turners 55, 56 which product may be first, a full sheet folded
longitudinally, second, two full sheets associated together and folded longitudinally,
third, a full sheet folded transversely and longitudinally; fourth, two full sheets
associated together and folded transversely and longitudinally; fifth, a half sheet
folded longitudinally.-If a slitter is mounted so as to bear on the paper upon the
internal guide G near its folding point t, Figures 19 and 20 Sheet X, said slitter
will operate to divide the web or sheet in its longitudinal centre so that the
product emerging from the rollers or turners 55 56 in any of the above forms will
be divided longitudinally and in the case of full sheets will be tantamount to
gathering two sheets printed side by side by a lateral transference. It will thus
appear that the size of the product emerging from the rollers or turners 55, 56 may
in length be equal to the length of a full sheet or that of a half sheet. Consequently
the carriers H I are provided with folding devices which are arranged to operate
upou both sizes of product, which for convenience we will call "full sheets" and
half sheets;" and as it is further apparent, that when the cutting is to be
performed by the carriers H and I (as in case the web emerges from the
turners 55, 56 having been transversely severed into short lengths) it will further-
more be necessary to provide the carriers H I with proper cutting devices to sever
such web into half sheets or whole sheets.-The folding mechanism operating upon
the sheets at this point may be of any of the well known constructions, whether
rotary in operation or constructed of turners as herein described. As here shewn
the rotary folding mechanisms supported by the carriers H. I. are shewn as well
adapted for completing the folding desired-These carriers are geared together by
toothed wheels 109. 110 (see Fig: 10) and will be driven in unison with the other
mechanisins by means of a bevel wheel 64 on the shaft of the carrier H which
wheel is engaged by a similar wheel 65 on a cross shaft 66 that carries a toothed
wheel 111 which through an intermediate 112 is geared to and driven by the
wheel 106 on the shaft of the carrier F
"
I will now describe the mechanisms with which these carriers are provided and
then explain their operation
The carrier H (see Fig: 18) is provided with four sockets at equidistant points
in its periphery in which the removable blocks supporting the tucking or creasing
blades 97 98 and other blocks carrying cutting blades 76 76 and sheet carrying
pins 53. 54 may be adjusted or removed. The carrier I is provided with sheet
seizing jaws the vibrating members 72. 73 of which are upon rockshafts and
actuated by a cam movement in any common manner.-The jaw 73 however is
here arranged to be rendered inoperative which may be done by removing its
actuating rock arm or by turning its rock shaft so as to project said jaw toward
the shaft of the carrier (shewn in Fig: 17). This carrier I is also provided at
points midway between the jaws 72. 73 with swinging folding blades 67. 68 and
between the said blade 68 and the jaw 73 with a third swinging folding blade 94
Figures 17 and 18. These swinging folding blades will be operated by suitable
cams but in this construction the folding blade 94 will be arranged so as to be
rendered inoperative which may be done by removing its rock arm or cam acting
thereon. This carrier I has also cutting slots provided in blocks 57. 58 and 75
which are removable from said carrier the block 75 being adapted to be inserted in
the opening in which the jaw 73 operates and the block 58 being inserted in a
suitable socket provided in the heads of the carrier. With this carrier I is arranged
(preferably beneath it) a pair of rollers 91, 92 which may be geared to and driven
by the toothed wheel 110 of said carrier and at a suitable distance from it another
pair of pulleys or rollers 131. 132 are arranged around which rollers tapes 129. 130
may be stretched, the tapes 129 either running around the carrier I and the roller
or pulley 131 or around the roller 92 and said pulley or roller 131 and the
tape 130 heing stretched from the roller 91 to the roller or pulley 132 or around

page_text: •
the roller 91 under the roller 92 and around the roller or pulley 132.-If now
we suppose the product emerging from the rollers 55. 56 to be a full sheets
length and it is desired to impart to it one transverse fold, the mechanisms
will be arranged as in Fig: 17, that is, the cutters 53. 54 and their pins
will be removed from the carrier H and the block provided with a cutting
blade 96 and pins will be substituted for the block carrying the creasing folding
blade 98 while the jaw 73 of the carrier I will be turned inward and rendered
inoperative and the cutting slot 75 adjusted in place. The swinging folding
blades 67. 68 and 94 will be rendered inoperative As such sheet or web emerges
from between the rollers 55. 56 its leading end will be impaled by the pins near
the cutter 96 which will carry said leading end around with the surface of the
carrier H. As the central part or folding line of the sheet overlying the creasing
folding blade 97 will be doubled thereby into the space provided by the jaw 72
which then stands open, the double edge thus formed will be nipped by said jaw
which closes thereon Thus held by its doubled edge the sheet will be carried
around with the carrier I between its surface and the rollers 91. 92 the end of one
of its plies being stripped from the pins and the two plies laid together to complete
the folding. The doubled edge is released by the opening movement of the jaw 72
accomplished in time to permit the folded sheet to be guided out between the
tapes 129. 130 or arranged as in Fig: 17. As the cutter 96 and cutting slot 75
come into operation they will sever the web to detach the folded sheet and impale
the leading end of the web upon the pins if the material is in the web form and
entirely uncut. If it is in the web form and partially severed transversely the
breaking bar might supplant the said cutting blade, if in the sheet form the pins
will simply engage the leading end of each sheet. If it is desired to impart a
second transverse fold to the sheet it may be accomplished by throwing into
operation the vibrating folding blade 94 in which case the block carrying the
cutting slot 58 must be removed and the tapes 129. 130 stretched as in Fig: 18.
as the central part or folding line of the once folded sheet reaches the rollers 91. 92
this plate 94 will be turned outward to double or fold said sheet into the nip of said
rollers which will then deliver it to the tapes 129. 130 which will carry it out from
between the rollers 131. 132 If it is desired to fold the product of a half sheets
length received from the rollers 55. 56 with a single transverse fold the creasing
folding blade 98 will be put in place of the cutter 96 and the cutters 76-77 and
the pins 53. 54 will be placed in position in the carrier H. In the carrier I the
block carrying the cutting slot 75 will be removed and the jaw 73 restored to its
operative condition. The folding blades 67. 68 and 94 will remain inoperative and
the tapes 129. 130 will be arranged as in Fig: 17. The material from the
rollers 55. 56 will be impaled upon the pins 53 carried around with the carrier H,
be folded by the folding blade 98 into the nip of the jaws 73, carried by the
latter around with the carrier I the doubled edge released and guided into the
tapes 129 130, the forward ply being dragged from the pins 53.-The next length
of material will be impaled upon the pins 54 folded by the blade 97 and jaw 72
in like manner. If the material is in the web form the cutters 76. 77 will sever it
into sheets or if in the partially severed form the breaker taking the place of said
cutter will separate it into sheets or if in the sheet form the pins 53, 54 will
engage it.
If it is desired to impart an additional transverse fold to these folded
half sheets, the folding blades 67. 68 will be thrown into operation, and the
tapes 129. 130 arranged as in Fig: 18, which sheets carried over the rollers 91. 92
will be released in proper time by the jaws 72. 73 to permit the same being
folded by the blades 67 or 68 into the nip of said rollers, through which they will
pass in a folded condition and from which they will be delivered by said tapes as
before described or as is apparent they may emerge directly from said rollers 91. 92
for delivery in any common manner by a piling or other sheet laying mechanism.
The sheets when once folded by the rollers 91. 92 will be delivered between said
rollers by a device like the fingers 5 hereinbefore described when the tapes will bo
dispensed with. -
