WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 13, Rue Gaillon,
Paris. "IMPROVEMENTS IN MACHINES FOR FOLDING AND DELIVERING PAPER."
This Invention relates to mechanism for folding and delivering paper, and is
specially adapted to hold paper passing from a cylinder of perfecting web press,
the paper passing through the press in continuous length from a roll and being
taken by the folding mechanism is folded in a direction transverse to its length
and cut, and is then folded in an opposite direction ready for transmission through
the mail, or for other purposes.
This Invention relates to the combination with a perfecting press of a movable
cylinder or carrier and a hinged blade or "fly" adapted to operate in connection
with a cutter to sever the paper, and then in the further movement of the cylinder
to press upon the severed ends of the folded paper while the fold itself is released
from the bite of the fold-nipping mechanism, the latter consisting of jaws.
Also in the combination with the hinged blade or “fly" of holding pins and a
dentated cutting blade provided with openings and adapted to serve as a stripper
to release the severed end of the paper from the holding pins.
Also in the combination with the cylinder or carrier and a pivoted or swinging
folding blade of a stop or deflecter to throw outward the edge of the folding blade
to fold and direct a piece of paper into the bite of a pair of feeding rollers.
Also in the combination with the fold-nipping mechanism and its carrier of
supplement cutters to sever the folded edge of the paper to produce half slicets, as
for supplements.

Also in the combination with mechanism adapted to fold a sheet in a line parallel
with the axis of the folding cylinder or carrier of an adjustable roller-carrying frame,
which may be thrown into or out of operation when it is desired to form a second
fold in a once-folded paper.
Also in a hinged folding blade and a feeding device arranged to form a second
fold in a sheet of paper in combination with a guide, a hinged or pivoted folder, and
mechanism working in connection therewith to form a fold substantially at right
angles to the second fold, as set forth.
The Invention also relates to mechanism for folding the web of paper issuing
from between the press or type cylinders of a perfecting press, or in other places
where it is desired to fold quarto sheets, and in this operation a knife or equivalent
is used to sever the web of paper longitudinally in combination with mechanism to
deliver one half of the sheet upon the other half, the sheets so lapped being pasted
at intervals if desired, after which it is folded.
And the Invention also consists in a new method of lapping paper to be folded
by folding mechanism, the shaft of the rotating cylinder or carrier is in this instance
the driven shaft, and the cylinder is connected and moves with it through pinions,
the shafts of the cylinders being mounted in hearings on the frame of any suitable
construction to properly sustain the working parts.
When the folding machine is to be employed to fold newspapers or other printed
matter issuing from a printing press the cylinder is placed at the delivering end of
the press with its axis parallel with the axis of the printing machine cylinders, and
the paper passing from the press is impaled on the points or holding pins that
project through slots in a movable cutting blade, having its edge preferably serrated,
it acting as one member of a cutting mechanism, the other member being the
fly" and corresponding set of holding pins. Assuming that the holding pins
have just entered the paper the rotation of the cylinder will carry the paper,
which in operation is already engaged and held by the holding pins at the left of
the cylinder, and will lay the paper over the support, then over the folder and a
slacker, the latter being carried by arms and projecting pins on the slacker rest on
stationary cams one at each side of the machine and provided with a depressed
part to allow the slacker to fall just as the folder commences to pass between the
jaws of the fold-nipping mechanism.
"6
The folder to fold a newspaper centrally is placed midway between the holding
pins, the latter holding that portion of the paper constituting the edges of the
newspaper, and these holding points and folding blades will be placed at such
distances in the cylinder as to hold and fold at the desired places. In this instance
the cylinder carries two sets of holding pins, two supports, folders and slackers.
When a movable cutting blade in the rotation of the cylinders reaches a "fly" the
paper extending forward from the fly" is severed, and the end of the paper
caught on the holding pins is carried toward the lower side of the cylinder, and
during this movement the folder comes opposite the jaws of the nipping mechanism
presses the paper lying on it between the jaws, folding the paper transversely, the
slacker bar giving up paper to form the fold and the jaws grasping the fold firmly,
and at the time the fold is commenced a finger on the shaft of the movable
cutter acts on a projection and turns the movable cutter to strip the paper from the
holding pins. The nipping mechanism holds the folded portion of the sheet, the end
of the sheet just discharged by the movement of the cutter drops upon the support,
which is preferably a sheet or strip of light spring metal, the edge of which holds
the free end of the 'paper up toward the cylinder and away from the holding
mechanism, composed in this instance of a lip and a yielding roller.
When the cylinder carrying the folded part of the paper has moved far enough
to bring a movable cutting blade and "fly" together, then the paper is severed and
the nipping mechanism then holds a paper with free ends, and the ends are both
held up by a support against the smooth face of the cylinder. The "fly" in this
instance is a bar carried at the ends of arms projecting from a shaft having con-
nected with it at one end a spring, the tendency of the spring being to hold the

page_text: "fly" against a cross plate or face of the cylinder. The shaft has attached to it
a pin that as the cylinder rotates strikes a stop just as the two free ends of the
newspaper held by the nipping mechanism are passing between the "fly" and the
roller of the holding mechanism, and when the pin engages the stop the fly shaft
is turned, the cylinder continuing to move, and the "fly" is thrown out away from
the cylinder in a tangential direction, the "fly" presses the free ends of the paper
down on the roller, or on other papers already folded and deposited there and lying
in a pile, to hold the paper, while the folded portion of the paper is released
from the nippers, and as the "fly" releases the free ends they are caught between a
lip and the roller held pressed upward by a spring coiled about the shaft from which
project the roller-carrying arms.
The action of the parts so far described will deposit papers once folded in a pile
and their folded edges will be substantially parallel or uniform sufficiently so to be
taken away in a pile ready for rapid hand folding.
In case half sheets or supplements are to be delivered it is only necessary to set
up the type to print half sheets and the folding goes on as usual, but to separate
the half sheets there is arranged in connection with the nipping mechanism a
supplement cutting mechanism.

the said William Morgan-Brown in the Great Seal Patent Office on the
13th December 1876.

A communication from abroad by Luther Childs Crowell, of Boston, Massachusetts,
United States of America.
This Invention relates to mechanism for folding and delivering paper, and is
specially adapted to hold paper passing from a cylinder of perfecting web press,
the paper passing through the press in continuous length from a roll and being
taken by the folding mechanism is folded in a direction transverse to its length
and cut, and is then folded in an opposite direction ready for transmission through
the mail, or for other purposes.
This Invention relates to the combination with a perfecting press of a moveable
cylinder or carrier and a hinged blade or "fly" adapted to operate in connection
with a cutter to sever the paper, and then in the further movement of the cylinder
to press upon the severed ends of the folded paper while the fold itself is released
from the bite of the fold-nipping mechanism, the latter consisting of jaws to bo
fully described.
Also in the combination with the hinged blade or "fly," substantially as herein
described, of holding pins and a cutting blade provided with openings and adapted
to serve as a stripper to release the severed end of the paper from the holding pins.
Also in the combination with the cylinder or carrier and a pivotted or swinging
folding blade of a stop or deflector to throw outward the edge of the folding blade
to fold and direct a piece of paper into the bite of a pair of feeding rollers.
Also in the combination with the fold-nipping mechanism and its carrier of
supplement cutters to sever the folded edge of the paper to produce half sheets, as
for supplements.
Also in the combination with mechanism adapted to fold a sheet in a line
parallel with the axis of the folding cylinder or carrier of an adjustable roller-
carrying frame, which may be thrown into or out of operation when it is desired
to form a second fold in a once-folded paper.
Also in a hinged folding blade and a feeding device arranged to form a second
fold in a sheet of paper in combination with a guide, a hinged or pivotted folder,

page_text: and mechanism working in connection therewith to form a fold substantially at
right angles to the second fold, as set forth, and in other features of Invention
hereafter described.
The Invention also relates to mechanism for folding the web of paper issuing
from between the press or type cylinders of a perfecting press, or in other places
where it is desired to fold quarto sheets, and in this operation a knife or equivalent
is used to sever the web of paper longitudinally in combination with mechanism
to deliver one half of the sheet upon the other half, the sheets so lapped being
pasted at intervals if desired, after which it is folded; and the Invention also
consists in a new method of lapping paper to be folded by folding mechanism.
In Sheet 1 Figure 1 is a side elevation of a folding mechanism provided with my
Invention; Figure 2, a longitudinal section thereof, except through the vertical
folding mechanism; Figure 3 is a cross section taken through the vertical folding
mechanism; Figure 4 is a view of the hinged folder detached; and Figures 5 and 6
are details, to which reference will be hereafter made.
Sheet Figure 1 represents a portion of a perfecting press with these improve-
ments added. Figure 2a is a top view thereof.
Figure 3 is a front view of the guide.
Figure 4a is a detail of the pasting devices.
Figure 5 a modification of the guide.
Figure Ga represents a sheet of paper as delivered from the cylinder showing
printed and unprinted portions; and
Figure 7 represents the guide m separate.
The shaft a of the rotating cylinder or carrier is in this instance the driven
shaft, and the cylinder c is connected and moves with it through pinions d, e, the
shafts of the cylinders being mounted in bearings on the frame fof any suitable
construction to properly sustain the working parts.
When the folding machine is to be employed to fold newspapers or other printed
matter issuing from a printing press the cylinder e is placed at the delivering end
of the press with its axis parallel with the axis of the printing machine cylinders,
and the paper passing from the press is impaled on the points or holding pins g
that project through slots in a moveable cutting blade h, having its edge i preferably
serrated, it acting as one member of a cutting mechanism, the other member being
the "fly" j, Figure 1, which shows one set of holding pins g just coming into
position to engage the paper issuing from the press but not shown, and the other
corresponding set of holding pins and its blade & are in the position they would
occupy immediately after severing the sheet of paper, and the paper or sheet
severed by the action of the moveable cutting blade h over the edge of the "fly" j
prior to its being severed, extended from the fold-nipping mechanism le composed of
several parts to be described.
Assuming that the holding pins at the right hand side of Figure 2 have just
entered the paper the rotation of the cylinder c and the direction of the arrow 1
will carry the paper which in operation is already engaged and held by the holding
pins at the left of the cylinder c, and will lay the paper over the support l, then
over the folder m and the slacker n the latter being carried by arms o and pro-
jecting pins p on the slacker n rest on the stationary cams q one at each side of
the machine and provided with a depressed part to allow the slacker n to fall just
as the folder m commences to pass between the jaws f, e¹, of the fold-nipping
mechanisin k, see Figure 2. The folder m to fold a newspaper centrally is placed
midway between the holding pins g, the latter holding that portion of the paper
constituting the edges of the newspaper, and these holding points and folding blades
will be placed at such distances in the cylinder as to hold and fold at the desired
places. It will be noticed that in this instance the cylinder c carries two sets of
holding pins, two supports, folders, and slackers.
22
When a moveable cutting blade in the rotation of the cylinders reaches a "fly
the paper extending forward from the "fly" is severed, and the end of the paper
caught on the holding pins is carried toward the lower side of the cylinder c, and

page_text: during this movement the folder m comes opposite the jaws f¹, e¹, of the nipping
mechanism, presses the paper lying on it between the jaws, folding the paper trans-
versely, the slacker bar giving up paper to form the fold and the jaws grasping the
fold firmly, and at the time the fold is commenced a finger on the shaft of the
moveable cutter acts on a projection 8 and turns the moveable cutter to strip
the paper from the holding pins g. The nipping mechanism holds the folded
portion of the sheet, the end of the sheet just discharged by the movement of the
cutter drops upon the support t which is preferably a sheet or strip of light spring
metal, the edge of which holds the free end of the paper up toward the cylinder
b and away from the holding mechanism, composed in this instance of a lip u
and a yielding roller v.
and
«
fly
"
When the cylinder carrying the folded part of the paper has moved far
enough in the direction of its arrow 2 to bring a moveable cutting blade
together then the paper is severed and the nipping mechanism
then holds a paper with free ends, and the ends are both held up by the support
t against the smooth face w of the cylinder. The "fly "j in this instance is a bar
carried at the ends of arms projecting from a shaft c having connected with it at
one end a spring y, the tendency of the spring being to hold the "fly" against the
cross plate or face w. The shaft x has attached to it (see Figure 1) a pin a¹ that
as cylinder b rotates strikes a stop 61 just as the two free ends of the newspaper
held by the nipping mechanism are passing between the fly and the roller v
of the holding mechanism, and when the pin engages the stop the fly shaft is turned,
the cylinder continuing to move, and the "fly" is thrown out away from the
cylinder in a tangential direction the "fly" presses the free ends of the paper down
on the roller v, or on other papers already folded and deposited there and lying in a
pile, to hold the paper, while the folded portion of the paper is released from the
nippers, and as the "fly" releases the free ends they are caught between the lip u
and the roller held pressed upward by a spring coiled about the shaft c¹ from
which project the roller-carrying arms d¹.
At the opposite end of the shaft x from that shown in Figures 1 and 2 is an arm
e that as the "fly" leaves the paper and the roller v bears against a cam f2 that
holds the "fly" and permits its axis x to turn gradually back to the positions
shown between the cylinders b and c or to cutting position.
The action of the parts so far described will deposit papers once folded in a pile,
and their folded edges will be substantially parallel or uniform sufficiently so to
be taken away in a pile ready for rapid hand folding.
In case half sheets or supplements are to be delivered it is only necessary to set
up the type to print half sheets and the folding goes on as usual, but to separate
the half sheets there is arranged in connection with the nipping mechanism a
supplement cutting mechanism, see Figure 2.
The nipping mechanism is composed of a stationary bar or jaw e¹ extending
across the cylinder b and a moveable jaw f1 faced preferably with india-rubber or
leather and carried at the ends of arms projecting from a shaft gl. In this instance
of the Invention the arms are loosely connected with the shaft g', a spiral spring h
being connected with the shaft and with the arms so as to allow the arms to move
for a short distance about the shaft when desired, a spring i connecting an arm on
the shaft and a stud j¹ on plate w so as to throw the jaw f¹ away from its stationary
jaw e¹.
At the proper time for the nipping mechanism to close on the paper presented by
the folder an arm k, Figure 1, mects the cam and closes the jaws, and the arm
bears on this cam as long as it is necessary to hold the folded paper, but when it
is to be released then the arm passes beyond the cam and the spring i throws back
the moveable jaw f¹.
On the shaft g¹ are arms m¹, to the outer ends of which is attached a cutting
blade n, the latter being guided in an opening made for its reception in the jaw f',
and the springs are connected one end to these arms m³, and the other to the
arms of the jaw ƒ'.

page_text: Now to operate the supplement cutting mechanism or the blade n¹ the moveable
cam piece o¹ is thrown up into action so as to give arm a greater movement,
which causes the shaft g' to move after the jaw fi meets jaw e¹ and carries with it
the blade n', which passes through the folded paper near the extreme edge of the
fold and cuts the paper into half sheets. At the lower side of the cylinder b is shown
a modified form of cutter, and instead of using the jaw c¹ as the cutting edge there is
connected with c¹ a spring blade p¹, the spring blade being connected at one end
only and extending diagonally across the edge of the cutter n¹ and being a spring
blade it wipes along the edge of n¹ producing a shear cut.
On the cylinder b are pivotted or hinged folders q', they being plates connected
each with a shaft, held in the position shown in Figure 2 by a spring 8¹, and each
blade has a finger t' adapted to engage a stop or deflector u on an adjustable roller-
carrying frame v provided with feeding rollers having pinions ¹ gearing
together and adapted to be thrown into engagement with teeth d of cylinder b
whenever it is desired to fold the paper a second time. This frame v¹ is pivotted at
a², has locking pins be adapted to be placed in one of the two holes c² to hold the
rollers up in engagement or out of engagement with teeth d.
When lifted into engagement a bar acts on arms d¹ of the roller vand depresses
the roller so that it cannot rise under the action of the spring and press the ends
of the paper up against the lip u. As the frame v¹ is lifted it moves a lever g²
connected with a lever he that slides a loose toothed hub 2 into engagement with
a bevil on a shaft k³, provided with a crank connected by link m² with a
crank n on the shaft of cylinder c, the shaft getting its motion in this instance
from shaft of cylinder c in this way, but many different devices or modes of connec-
tion might be employed instead of the connections shown.
The frame when in its olevated position places the deflector u¹ in the path of
the finger t¹ of the pivoted folder q¹, and stops or detains the folder causing its
edge to turn outward from the cylinder band to bear against the paper already
once folded and fold it and press the bight or fold between the faces of the moving
rollers w¹, w, which then carry the paper away, folding and feeding it into a
guide o, it being a series of upright narrow plates at the side of which is a
vibrating double folder p², connected with a vertical shaft, supported in bearings
and provided with fingers adapted to be struck by projectious s² on a toothed
wheel 2, on the vertical folding cylinder adapted to fold the papers in a direction
opposite to the direction in which they were folded by cylinders b, c.
A pin at the lower end of the shaft q² rests on a double inclined crown cam u²
which serves the purpose of turning the shaft q2 of the double folder back to its
normal position after each operation, the weight of the shaft and folder being
sufficient to ride down the cam faces.
The shaft of the vertical folding apparatus has at bottom a bevil gear w
engaged by the bevil on shaft 2. This vertical cylinder is provided with nipping
jaws a³, b, and with moveable vertical folders held by springs and provided wit!!
fingers, as are moveable folders q¹, a deflector engaging such fingers to throw the
vertical noveable folders e outward to cause them to fold the papers passed from
the guide o by the double folder 22, and held between the parts a, b, of the
vertical nipping mechanism, and as the papers so folded are carried around by the
vertical cylinder each vertical folder under the action of the deflector d³ folds
the paper and forces the fold made through or into the bite of the vertical rollers
provided with gear and operated from the pinion t².
The shaft of each jaw ba has a shoe n³ that bears against a stationary cam o³ on
a plate p³ in which the shaft v2 turns.
In Figure 6 the shoe n³ at the right is just about to strike the cam 03, and the cam
will move n³ and throw the jaw 63 toward the jaw a³, and cause the jaws to grasp a
folded paper and carry it beyond the rollers ea and after the folder 3 folds the paper
the shoe n³ leaves the cam o³, and the springs connected with the jaws (see Figure 3)
open the jaws and release the paper.

page_text: Papers issuing from between the vertical rollers e³ in this instance folded four
times are fed rapidly into a mailing or wrapping box, in which is placed a packer f³,
it being a vibrating arm carried by a rocking shaft g, at the lower end of which
is a crank ³ connected by link is with an excentric strap embracing an eccentric on
the shaft. The papers are moved alternately into the boxes 3, 3, in which are
placed moveable slides ³, which are gradually moved back as the boxes and slides
are filled. The papers are prevented from crowding backward to the rollers e³ by
spring fingers m³. With this packer may be connected a counting mechanism to
indicate the number of papers folded.
It will be seen by those conversant with mechanism that the mechanical details
for operating the parts actively engaged to fold the paper and deliver it as described
can be varied without departing from this Invention, as equivalently operating,
connecting, and driving mechanism may be employed.
The principal element of the supplement cutter is a blade carried by a nipping
jaw, and adapted to slide on or in such jaw, and in this part of the Invention it will
be noticed that the blade is moved to sever the paper after the paper is grasped and
held by the jaw, and the moveable jaw and cutter are both moved by the same
shaft, the jaw, however, being connected with the shaft so that the latter with the
blade can move further than the jaw.
This feature of this Invention could be carried out by many different connecting
and operating devices other than those shown which would be mere equivalents, s0
this portion of this Invention is not intended to be limited to the mechanism shown.
The supplement cutter might be placed in connection with the stationary jaw,
and have mechanism arranged to operate it after the jaws met to grasp the paper.
Springs restore the folders to position against jaws b³ after passing out from
between the rollers e³.
The part u of the holding mechanism might be hinged, and be arranged to be
moved backward as the "fly" presses the paper down, and to come forward over
the end of the paper like a hook when the "fly" moves away. A spring bar or rod
might take the place of support t.
'
In the description of the mechanism Sheet Figures 1 to 7, it will be
remembered that the cylinders b, c, are intended to correspond with the cylinders or
carriers b, c, in Figure 1, Sheet 1, and the mechanism illustrated on Sheet
Figures 1 to 7ª may be described as follows, viz :-
The cylinder a¹ is covered with cloth and is one of the usual impression cylinders,
and opposed to it is the type cylinder 61, the web of paper e being supplied in this
instance from a roll d, herein shown as located near the impression cylinder.
In this instance of this Invention the web is of a width to produce a quarto or
double sheet paper, and a portion of the web issuing from between the impression
and printing cylinders is left unprinted, the unprinted portions running longitudinally
through the centre of the web, and transversely of the web, as denoted in Figure 6
by lines 1, 2. This printed web is then cut longitudinally at or near the centre of
the unprinted line 1 by a positively rotated or other suitable cutter f, on a shaft
carried by arms g of a rock shaft 7, the edge of the cutter entering a groove 3 in a
bed roller i, by which the paper is supported on its side opposite the cutter. One
half 4 of this web is passed up over the first cylinder a and then under the second
cylinder of the pair of folding cylinders provided with blades, and jaws, and
cutters, to fold and sever the sheet transversely on the alternate lines 2, Figuro Ga,
such cylinders and mechanism being fully described, Sheets 1, and the portions 2
remaining uncut serving as the line on which the completed paper is folded from
top to bottom, or the white central portion parallel with the length of the columns.
The other half 5 of the web is led down over a leading roller 1, and about a
guide m composed, as shown in Figures 1ª and 3ª, of a V shaped frame, preferably
clad at its edges with sheet metal formed as cones, the ends of largest diameter
being nearest the leading roller, and the smaller ends coining substantially together
The metallic edges are shown in dotted lines Figure 3. It will be noticed
the portion 5 passes in Figure 3ª down in front of the guide, then back about the
at n.

page_text: eft-hand edge, then across the back of the guide, as shown by the dotted arrow,
then around the other edge up in front of the guide and under, and then over the
roller where it is delivered against the under side of portion 4, with its outer
edge 6 at the centre of the machine, and substantially paralled with the inner edge
of the portion 4, and in this way the folding cylinders are made to operate on a
web composed of two thicknesses of paper instead of one as usual, and a broad
sheet for a quarto paper may be manipulated as readily as if the sheet was narrow
for newspapers known as "single sheet."
The impression cylinder has affixed to its cloth or felt cover at intervals from its
centre to one end a number of paste applyers, consisting in this instance of this
Invention of pieces o of sheet metal of the form shown in Figure 4ª, the barbed or
hooked ends p passing through the cloth covering and the flat ends 7 at each
rotation of the impression cylinder wipe over and against the surface of a roller
revolving in a paste trough c. These paste applyers o act to deliver spots of paste
or gum on each alternate unprinted portion 2, and at the under side of the half 4 of
the web, and when the half 5 is laid against the under side of the half 4, as described,
the paste or gum causes the parts 4, 5, to adhere together on each alternate line 2,
this paste serving to keep the two sheets together at their centres, the two sheets
forming the folded paper, and the quarto paper delivered, as described, will have its
two sheets attached at their centres parallel with the length of the printed columns
and all the edges of the paper will be cut ready to be opened as the leaves of a book.
The paste may be applied in other ways than herein described, as, for instance, by
a vibrating striker or arm arranged to strike the portion 4 of the sheet under the
roller in advance of the leading roller.
The cutter shaft 8 will be driven by a belt or gear in any suitable way and from
any proper moving part of the machine, and its carrying arms will be arranged to
inove toward or from the roller i to sharpen the cutter or for purposes of adjustment.
Instead of the guide m, constructed as shown in Figures 1a and 3ª, a cylindrical
guide S may be placed diagonally across the entire sheet e and lead the portion 5
backward, around, under, and up over it, and then to the under side of portion 4, as
before described.
It is considered that a web of paper has never before been split when leaving
the press or folding machine, and been then delivered one half under the other
half to be subsequently folded, as herein described, and it is not therefore intended
to limit this Invention to the exact devices described as many equivalents for each
of the parts may be made.
It is evident that the blade / might be stationary on the cylinder and then the
pins g would be placed on a rock shaft which would be so moved as to cause the
points of the pins in such case crooked to be projected through the openings in the
plate, and beyond the periphery of the cylinder and into the web, and to be drawn
back out of the web.
Having now described and particularly set forth the nature of the said Invention,
and the manner of carrying the same into effect, I would have it understood that
what I claim is-
First. A rotating cylinder or carrier in combination with a hinged blade or "fly"
adapted to operate in connection with a cutter to sever the paper, and then
