IMPROVEMENTS IN APPARATUS FOR MAKING UP SHEETS, OF PRINTED PAPER INTO
THE FORM OF PAMPHLETS, MAGAZINES, OR NEWSPAPERS." [A communication from
abroad by Richard March Hoe and Stephen Davis Tucker, both of the City and
State of New York, United States of America.]
This Invention relates to various improvements upon Inventions for which
Letters Patent were granted respectively to William Edward Newton, as a commu-
nication from Richard March Hoe, dated August 28th 1872, and to William
Conquest, as communications from Stephen Davis Tucker, dated respectively
September 4th 1875, No. 3105, July 26th, 1876, No. 3019, November 30th, 1876,
No. 4645, 30th May, 1877, No. 2110, and consists of various modifications in the
sheet collecting, folding, pasting, and delivering mechanism therein described.
Hitherto the primary mechanism, either collecting or folding, which received the
sheets from the printing machine was necessarily driven at the same speed as the
printing machine, and the sheets were delivered into two separate channels alter-
nately, which channels conducted them to secondary apparatus driven at half
speed.
In this arrangement of apparatus the channels leading to the secondary apparatus.
are liable to become choked, and this defect is removed by the present Invention..
The primary mechanism consists of a collecting cylinder similar to those shown and
described in several of the above mentioned Patents, and furnished with the

page_text: necessary tapes and fingers for receiving, holding, and carrying the sheets upon its
periphery in any desired number; and the secondary mechanism consists of a
folding cylinder driven at a considerably reduced speed, and mounted in the machine
at about the distance apart of the length of a sheet. It has been found that large
sheets cannot be pushed or driven from the one mechanism to the other smoothly
and with certainty without curling or buckling by the ordinary tapes alone.
To obviate this inconvenience, and to aid in carrying the sheets onward in a proper
manner a pair of sheet forwarding rollers mounted intermediate of the two cylinders
and driven at the same speed as the primary mechanism or collecting cylinder are
provided. The upper roller is mounted loosely on lever arms, which are operated
by means of a cam so as to bring it into frictional contact with the lower roller,
which is driven in any suitable manner, so that as the sheets of paper emerge from
the collecting cylinder and reach the forwarding rollers, which nip them and draw
them on until the leading ends of the sheets are about to be seized by the fingers of
the folding mechanism, they are left to be carried onward at the slower speed of
this secondary mechanism.
The gripping mechanism consists of grippers mounted as usual on a spring seated
shaft, but having their sheet discharging cam fixed on the arm of a bell crank lever
pivotted on a stud. in the frame, and rocked by an excentric so as to open and
release the sheets at the discharging channel at such times only as the channel is
opened. The grippers are opened to receive the sheets at each rotation of the
cylinder by a fixed cam as usual.
The secondary mechanism or folding cylinder may be constructed and operated
as described in the before mentioned Patents, but when the paper to be folded is
supported upon the folding cylinder it is preferred to construct and operate the
folding mechanism in the following manner:-The shaft of the rotary folder is
mounted at the end of a pair of arms keyed to a rocking shaft, which is carried in
bearings in the heads of the folding cylinder. One of these arms is extended beyond
the rock shaft, and carries a stud or bowl, which runs in the groove of a stationary
cam attached to the framing of the machine. The shaft of the rotary folder carries
a pinion which takes into an intermediate wheel (mounted loosely on the rock
shaft) which gears with a stationary spur wheel attached to the frame. By this
means the folding blade as it revolves around the shaft of the cylinder may be con-
tinuously rotated, whether the blade in its rotation projects beyond the periphery
of the cylinder or is wholly within the cylinder. Thus, the folding blade may be
made to rotate, say, four times during one revolution, and to project the blade
beyond the periphery of the cylinder only once, that is, as the blade passes the
folding rollers and is required to thrust the sheets into the bite of the rollers.
As a modification of the above arrangements the shaft which carries the grippers
is provided at each end with a cranked. arm, furnished with studs or bowls.
One
of these cranked arms is actuated to open the grippers to receive the sheets by
being brought during the revolution of the cylinder against a fixed cam on the
framing. The bowle of the other crank arm is acted on by an auxilliary cam
attached to the face of the folding blade projecting cam, whereby the grippers are
opened at the proper time to release the sheets when they are to be folded. The
collecting cylinder may be provided with a continuously rotating folding blade
carried in arms projecting from a rock shaft mounted within the head of the
cylinder, continuously rotated by a pinion driven by two intermediate wheels from
an annular ring of internal teeth secured to the frame of the machine. The inter-
mediate wheel pivotted. on the rock shaft is wide enough to gear with the other
intermediate wheel carried by a stud axle on the cylinder and with the 'pinion on
the shaft of the folding blade in different planes to allow of the pinion moving in
and out free of the annular ring of teeth. The crank arm of the folder shaft
carries a bowl, which enters the groove on the face of the folder blade projecting
This face cain is mounted loosely on the shaft of the collecting cylinder, and
secured to the framing by stud screws when required to be used as a stationary
cam, and its boss is provided with set screws, by which it can be firmly attached to
cam.

page_text: "
the shaft of the collecting and folding cylinder when it is required to be rotated
therewith, and on its outer face is attached a spur wheel by which through a train
of gear the cam can be rotated independently of the cylinder. When employing
the folder projecting cam as a stationary cam with the mechanism above described,
every sheet received from the printing machine will be folded and delivered to be
further manipulated by a second folding cylinder, or by transverse vibrating folding
mechanism. The collecting and folding cylinder is furnished with mechanism
whereby any desired number of sheets may be collected and delivered therefrom in
a single body to be folded or flown," as desired. When the folder projecting cam
is adjusted so as to rotate in unison with the cylinder the folding blade will con-
tinuously rotate, but without being projected from the cylinder, and the auxiliary
cam will no longer act on the grippers. The mechanisin is therefore enabled to
receive sheet after sheet upon the cylinder until the desired number is collected
thereon. When the toes of the delivering switches are rocked into the grooves of
the cylinder they intercept the heads of the collected sheets, strip them off the
cylinder, and deliver them over a roller in front of a fly frame to be laid in a pile.
The mechanism for operating the switches and fly is well known. When the folder
projecting cam is released from the cylinder and frame it is free to be rotated
through the spur wheel attached thereto in the same direction as the cylinder at
the desired relative speed by a train of gear from the cylinder, so as to make one
or more rotations to two or more rotations of the cylinder, and thus will collect two
or more sheets and fold them. If the longitudinal posting mechanism about to be
described be adapted to this collecting cylinder, the sheets to be folded will also be
pasted together at any desired part of their width.
In some cases the folder projecting cam may be so mounted as to be capable of
being reciprocated towards and from the folding rollers, or laterally towards and
from the cylinder head into and out of engagement with the rock arm of the folder
blade shaft. In the first case the groove for operating the bowle on the rock arm
of the folder shaft is made in the face of a plate, and takes the form of an ellipse.
This plate is mounted in guides on the frame, and reciprocated to and from the
folding rollers by a stud carried by the plate entering a groove in a face cam driven
by gear wheels from the cylinder at any desired relative speed. The reciprocating
cam plate may therefore be carried into a position to remove the folding blade
within the cylinder at one rotation of the cylinder, and at the next to allow of it being
projected therefrom to fold the two sheets collected. In the latter case the folder
projecting cam is mounted loosely on the shaft of the collecting cylinder, and
attached to rods which slide in bearings through the framing of the machine, and
are connected together by a cross bar carrying a stud or bowl entering the groove
of a cam mounted upon a stud axle carried by the frame of the machine.. This cam
is rotated by spur wheels from the cylinder, and is formed with a throw sufficient
to cause the groove of the folder projecting cam to engage with and disengage from
the bowl carried by the rock arm of the folder shaft. When the cam is reciprocated
outwards from the cylinder, and disengaged from the rock arm, the folder is held
out of action within the cylinder by a spring seated rod with which the rocking
frame, of the folder is fitted. When the cam is again reciprocated towards the
cylinder its groove again receives the bowl of the rock arm and operates the folder.
If therefore the gearing is suitably proportioned any desired number of sheets can
be collected before the folder is allowed to act.
The secondary folding mechanism may be similar to that first described in con-
nection with the primary folding cylinder, and the folding blade caused to rotate
any desired number of times relative to its revolution by suitably proportioning its
spur gear, or the sheets once folded may be conducted to subsidiary folding mechanism
provided with vibrating folding blades.
When cylinders provided with one or more continuously rotating folding blades
are employed they may be made to deliver sheets into two sets of folding rollers
alternately, as desired. This is effected by mounting on the end of the folding
blade shaft and outside the cylinder head a pinion gearing with the internal teeth

page_text: of an excentric oval wheel which has the centre of the cylinder for one of its foci,.
whereby that portion which extends towards the folding rollers is excentric to the
cylinder. This oval wheel is mounted loosely on the axle of the cylinder, and is
caused, by means of a connecting rod and crank pin, to oscillate so as to present
alternately its excentric portion to one of two pairs of folding rollers mounted and
driven in any convenient manner.
This oval wheel is connected with a grooved cam, the groove of which is con-
centric with the periphery of the oval wheel.. Into this groove enters a bowle carried
by a rock arm of the folder shaft, so that its pinion is kept in gear with and rotated
by the oval wheel, and while following the excentric portion of the wheel the blade
is projected beyond the cylinder and inserted between and withdrawn from the
folding rollers. The sheets folded by this cylinder may be conducted from each
pair of folding rollers by channels formed by tapes and guides to a second folding
cylinder to be again folded on a line parallel to the first fold, or at right angles
thereto by vibrating folding blades.
As a modification of this folding apparatus an oval wheel may be attached to the
frame at each end of the cylinder, the excentric portion of one wheel being towards
one pair of folding rollers, and the excentric portion of the other wheel towards
the second pair of folding rollers. The cylinder is provided with two folding blade
shafts, actuating pinions, and is arranged to receive two sets of grippers. One of
the folding blades is also removable, and a gripper may be substituted therefor if
desired. The auxiliary gripper cam is also removable from the face of the blade
projecting cam at one side of the cylinder, and a main gripper cam can be attached
to the inner face of the opposite blade projecting cam. By this arrangement of
folding mechanism, viz., with two folding blades and two sets of grippers, half
sheets can be rapidly folded, the first half sheet being folded between one set of
folding rollers by one folding blade, and the next half sheet between the other set
of folding rollers by the succeeding folding blade. By removing one folding blade
with its shaft, and substituting a set of grippers, large sheets of paper may be folded
through one pair of rollers only.
As a modification of part of the above, the internal toothed wheel may be circular
and fixed to the frame of the machine, but of greater diameter than the cylinder,
and set.excentric thereto in the direction of the folding rollers. Two excentric
grooved cams, one being attached to the annular wheel, and the other to the frame
of the machine at the opposite end of the cylinder are employed to operate the
folding blade, the shaft of which carries a pinion in gear with the internal teeth of
this wheel; this shaft is mounted in boxes which slide on the heads of the cylinder.
These boxes carry bowls that enter the grooves of the excentric cams, and the
folding blade is thus, while rotating, caused to enter between and withdrawn from
the folding rollers. Stationary excentrics may be employed, the straps of which are
connected to the boxes carrying the shaft of the folder blade. In this arrangement,
the driving pinion being suitably proportioned to the internal toothed wheel, will.
be forced to remain in gear with the wheel as it is revolved, and may make, say,
three rotations to one of the cylinder, two of which are inside the periphery of the
cylinder, but during the other the blade is projected from and withdrawn towards
the centre of the cylinder to perform the folding operation.
In order to lay a line of paste longitudinally of the paper a pasting disc sup-
ported in fixed bearings and running in a paste vat is mounted so that its periphery
shall touch the paper on the collecting cylinder. The cylinder is grooved on a line
coinciding circumferentially with the position of the paste disc, so that when not in
contact with a sheet of paper thereon the surface of the cylinder will not be smeared
with paste. By. this arrangement a longitudinal line of paste may be applied to
alternate or to all but the last of any number of sheets collected upon the cylinder.
In order to apply a transverse line of paste upon the surface of a sheet of paper
while passing over a revolving supporting cylinder, a pasting blade provided with
recesses to span the supporting tapes is carried in a radial position from a shaft to
which it is attached adjustably. This shaft is geared with a paper supporting

page_text: cylinder at one side, and at the other with a paste fountain roller, so that the edge
of the blade and the periphery of the cylinder and roller shall have the same surface
speed. The shaft is set at such a distance that the edge of the blade shall engage
and move in unison with the surface of the paste. fountain roller to receive, paste
therefrom, and with the surface of the sheet of paper passing over the supporting
cylinder to deposit the paste thereon without dragging or sweeping over the surface.
The paper supporting cylinder is also provided with a stripper and a wiper, the
former consisting of a thin plate of metal to scrape off the paste deposited thereon.
when the machine is run without sheets of paper, as is the case in commencing or
finishing work. The wiper consists of a metal saddle piece or frame, over the open
bottom of which is stretched a number of layers of flannel or other soft clothing.
This wiper is caused to bear by its own weight or by pressure screws upon the
surface of the paper supporting roller, and will clean off as the cylinder rotates any
paste adhering thereto, so that the cylinder when presented to the next sheet of
paper will be perfectly clean.
When the partially divided web is to be pasted the ordinary carrying tapes may
be dispensed with.
"
In delivering the printed sheets from the printing machine, or from the first
rotatory folding cylinder to the secondary folding mechanism, the great speed at
which they issue causes them when stopped to "
buckle up." To avoid this.
buckling" the sheets are brought to the vibrating folding mechanism between
tapes carried by rollers, and immediately before entering beneath the folding blade
are nipped at several points in their width between brake arms and rest blocks
mounted respectively below and above the sheets. The rest blocks are carried upon
a bar attached to the fratning, and are, together with the brake arms, adjustable
laterally to suit the various margins of the printed matter. The brake arms are
mounted on a shaft operated by a cam suitably placed for the purpose to raise the
sheets momentarily near their rear ends, and press them against the brake blocks,
so as to suspend or retard their movement and allow the forward end or leading
edge to approach the stop or gauge gently, and abutt against the same without
danger of "buckling."

WILLIAM CONQUEST, of Tudor Street, in the City of London, Mechanical Engineer.
"IMPROVEMENTS IN APPARATUS FOR MAKING UP SHEETS OF PRINTED PAPER INTO
THE FORM OF PAMPHLETS, MAGAZINES, OR NEWSPAPERS." A communication from
abroad by Richard March Hoe and Stephen Davis Tucker, both of the City and
State of New York, United States of America.
This Invention relates to various improvements upon Inventions for which
Letters Patent were granted respectively to William Edward Newton, as a commu-
nication from Richard March Hoe, dated August Twenty eighth, One thousand
eight hundred and seventy two, No. 2561, and to William Conquest, as communi-
cations from Stephen Davis Tucker, dated respectively September Fourth, One
thousand eight hundred and seventy five, No. 3105, July Twenty sixth, One
thousand eight hundred and seventy six, No. 3019, November Thirtieth, One
thousand eight hundred and seventy six, No. 4645, Thirtieth May, One thousand
eight hundred and seventy seven, No. 2110, and consists of various modifications in
the Sheet, collecting, folding, pasting, and delivering mechanisms therein described.
Hitherto the primary mechanism for either collecting or folding, which received
the sheets from the printing machine was necessarily driven at the same speed as
the printing machine, and the sheets were delivered into two separate channels
alternately, which channels conducted them to secondary apparatus driven at half
speed..
In this arrangement of apparatus the channels leading to the secondary apparatus.
are liable to become chocked, and this defect is removed by the present Invention.
The primary mechanism consists of a collecting cylinder similar to those shewn and
described in several of the above mentioned Patents, and furnished with the,
necessary tapes and fingers for receiving, holding, and carrying the sheets upon its
periphery in any desired number, and the secondary mechanism consists of a folding
cylinder driven at a considerably reduced speed, and mounted in the machine at
about the distance apart of the length of the sheet. It has been found that large
sheets cannot be pushed or driven from the one mechanism to the other smoothly
and with certainty, without curling or buckling by the ordinary tapes alone. To
obviate this inconvenience and to aid in carrying the sheets onward in a proper
manner, a pair of sheet forwarding rollers mounted intermediate of the two cylinders
and driven at the same speed as the primary mechanism or collecting cylinder, are
provided. The upper roller is mounted loosely on lever arms, which are operated
by means of a cam, so as to bring it into frictional contact with the lower roller
which is driven in any suitable manner, so that as the sheets of paper emerge from
the collecting cylinder and reach the forwarding rollers which nip them and draw
them on until the leading ends of the sheets are about to be seized by the fingers of
the folding mechanism, they are left to be carried onward at the slower speed of
this secondary mechanism.
The gripping mechanism consists of grippers mounted as usual, on a spring seated
shaft, but having their sheet discharging cam fixed on the arm of a bell crank lever
pivotted on a stud in the frame, and rocked by an excentric so as to open and
release the sheets at the discharging channel at such times only as the channel is
opened. The grippers are opened to receive the sheets at each rotation of the
cylinder by a fixed cam as usual.
The secondary mechanism or folding cylinder may be constructed and operated
as described in the before mentioned Patents, but when the paper to be folded is
supported upon the folding cylinder, it is preferred to construct and operate the
folding mechanism in the following manner:-The shaft of the rotary folder is

page_text: mounted at the end of a pair of arms keyed to a rocking shaft, which is carried in:
bearings in the heads of the folding cylinder. One of these arms is extended beyond:
the rock shaft, and carries a stud or bowl which runs in the groove of a stationary.
cam attached to tho framing of the machine. The shaft of the rotary folder carries
a pinion which takes into an intermediate wheel (mounted loosely on the rock
shaft) which gears with a stationary spur wheel attached to the frame. By this
means the folding blade as it revolves around the shaft of the cylinder, may be.
continuously rotated whether the blade in its rotation projects beyond the periphery.
of the cylinder, or is wholly within the cylinder. Thus, the folding blade may be
made to rotate, say, four times during one revolution, and to protect the blade
beyond the periphery of the cylinder only once, that is, as the blade passes the
folding rollers and is required to thrust the sheets into the bite of the rollers.

sheet manipulating.apparatus; in_Figures 2 and 3 the tapes are omitted..
In order to a clear understanding of the present improvements, the construction
and operation of the apparatus shewn in Figures 1 to 11, will first be described and
then the modification of the same explained.
ነ
The primary sheet-manipulating apparatus consists of a revolving cylinder 20
upon the surface of which several sheets may be collected one upon another and
stripped or discharged therefrom in a single mass or body. The cylinder 20 is
mounted upon a shaft 19, which is rotated by gearing connecting it with one of the
shafts of a web printing machine to which this delivering apparatus is adapted..
The tapes 51, 52, form conductors leading from the cutting cylinders of the
printing machine, and operate to deliver the sheets formed thereby onto the cylinder
20. The tapes 51 return over a roller 81, which is driven by a pinion 90 from a
toothed wheel 96 on the shaft 19, and the tapes 52, driven in concert with the tapes
51, return over pulleys 80 towards the cutting cylinders, while guards 60 bridge the
space between the periphery of the cylinder 20 and said pulleys 80, thus formning,
with the tapes 51, a continuous conductor up to the surface of the cylinder, which
latter, having a greater surface speed than the cutting cylinders, accelerates the
movement of the sheets and separates them a suitable distance apart to facilitate
their manipulation and provide a space for grippers, if used, as is well understood.
This cylinder is provided with a second set of tapes 53, which are stretched from
a roller 84 driven by a pinion 92 from the wheel 96. The tapes 53 extend partially
around the cylinder over a roller 82, which is driven by a pinion 91 from the wheel
96, and they then return under a roller 83. The circumferential portion of the
cylinder 20 which is unoccupied by the tapes 51 and 53 is spanned by the depending
arms of the guards 60, which, with the tapes 51, forin the entrance channel for the
sheets while the switches 70, with the roller .81, form the discharging channel for
the same.
These switches 70 also operate to close this latter channel and guide the
sheets around with the cylinder, and are keyed upon a shaft 10 which is rocked by
means of a rock arm and a connecting rod 80, whose stud or friction roller runs in
the cam groove 34 of the cam wheel 97, which latter has a toothed periphery which
gears with a pinion 93 on the shaft 19. As this pinion 93 makes equal turns with
the cylinder 20, and is but one half the diameter of the cam wheel 97, it follows that
the switches 70 will be vibrated in opposite directions at each revolution of the
cylinder 20, standing in the position shewn in Fig. 5, Sheet III., at one revolution;
and in the position shewn in Fig. 4, Sheet II., at the next revolution.
This apparatus operates as follows:-Each sheet delivered on to the cylinder 20
from the tapes 51, 52, is nipped upon its surface by the tapes 51, and driven around
with said cylinder, the switches 70 then standing as in Fig. 5, and acting to guide

page_text: the sheet into the nip of the tapes 53; and with the guards 60 aiding its onward
movement, so that it is carried around to the entrance channel, where it receives a
second sheet upon it. These two sheets now travel together, and since the switches
have meanwhile been rocked into the position shewn in Fig. 4, said sheets will be
guided off from cylinder 20 at its discharging channel.
It is obvious, however, that the switches 70 may be so timed or operated as to
deliver the sheets from the cylinder 20 in packs of 3 or any other number, by
properly proportioning the teeth of the cam wheel 97 to those of the pinion 93, as
is well understood.
Heretofore it has been found advantageous to supply the collecting apparatus
with sheet controlling grippers, which have been opened to release the sheet at
every revolution of the cylinder immediately after passing the discharging channel.
In the present improvements the grippers 95, though hung on a spring seated
.shaft rocked by a cam, as is common, have their sheet discharging cam 64 fixed on
one arm of a vibrating bell crank 35, see Figures 7 and 8, Sheet II., which is pivotted
on a stud 17 and rocked by an excentric 37 on the shaft 36 of the toothed-wheel-
97, whereby said grippers, through the rocking arm 71, are opened to release the
sheets at the discharging channel at such times only as said channel is opened and
the sheets are to be discharged, but said grippers are opened at the receiving channel
at each revolution of the cylinder 20 by a fixed gripper cam 63 with which the
rocking arm 71 engages. These grippers 95 thus open to receive, and close to seize,
the sheet at each revolution of the cylinder 20, remain closed while passing the
discharging channel, when the switch stands as in Fig. 5, and are opened to release
the sheets as in Fig. 6, when said sheets are to be discharged by the switch as therein
.shewn.
The secondary sheet manipulating apparatus consists of a cylinder 30, which is of
the same size as and is revolved at one half of the surface speed of the cylinder 20
by means of a toothed wheel 72 fast on the shaft:68, which is driven through the
train 99, 98, 97, from the pinion 93 on the shaft 19 of the cylinder 20. At one end
of the cylinder 30 is a toothed wheel 73 which meshes with a similar wheel 74 on
the shaft of a folding roller 61, which latter gears with the wheel 75 on the roller
62, these rollers being rotated in unison and at the same surface speed as the cylinder
30. A rotary folder 6, see Figures 2 and 4, is keyed upon a shaft 1 carried by rocking
arms 7, 8, fixed upon a rocking shaft 9 mounted on the heads of the cylinder 30.
The arm 8 has an extended shank carrying a stud or friction roller which runs in
the groove of a stationary cam 21 fixed to the side frame of the machine. By this
construction of parts the cam 21 will rock the arms 7, 8, and project the blade shaft
1 outward from and withdraw it within the periphery of the cylinder 30 at each
revolution of the latter.
The blade shaft 1 is also provided with a pinion 3 fast upon it, which pinion is
geared with an intermediate toothed wheel 4, which turns freely on the shaft 9 and
remains constantly geared with a stationary toothed wheel 5 fixed to the framework
of the machine, in this instance being attached to the cam 21, see the detached view
Fig. 11; and as this intermediate wheel 4 and arms 7, 8, supporting the blade shaft
1 to which the pinion 3 is fixed are hung on the same shaft 9 the pinion will remain
constantly geared with and be driven by the said intermediate wheel 4, whatever
may be the degree.to which the blade shaft 1 is projected by the cam 21.
. The operation of this apparatus is as follows:-As the cylinder 30 rotates it
carries with it the shaft 9, the intermediate. wheel 4, the blade 6 and its shaft 1, and
pinion 3, thereby causing the wheel 4 to be turned by the stationary wheel 5, and
to constantly rotate the folding blade 6 through the pinion 3. Thus at each rotation
of the cylinder 20 the said folding blade will be rotated a number of times, according
to the proportion its carrying pinion 3 has to the driver 5. In this instance this
proportion is at 1 to 4, and hence the blade 6 will make four rotations to each rota-
tion of the cylinder 30, and will be turned outward from the centre and toward the
periphery of the cylinder four times during each single rotation of the cylinder, as
is indicated by dotted lines in Fig. 10, Sheet III. When, however, the folding blade

page_text: is approaching the folding rollers 61, 62, the stud or friction roller on the arm 8 will,
by entering the depressed portion of the stationary cam 21, cause the blade carrying
shaft to be gradually moved outward from the centre of the cylinder, and since said
shaft is constantly rotating the blade, these combined movements will cause the
blade to be projected toward and entered between the folding rollers 61, 62, Figs. 4
and 6, its edge thus being caused to move in a curved line nearly coinciding with
the surface of the roller 61. The depressed part of this cam 21 is so shaped that
when the blade has fully entered between said rollers, as in Fig. 4, by the outward
movement of its shaft and its rotation therewith its continued rotation will with-
draw it from the folding rollers, while its shaft 1 is gradually moved inward, so as
to draw the folding blade within the periphery of the carrier, the movements of said
shaft.and folding blade and the curved line which the edge of the latter describes
being the reverse of those which projected the said blade.
During the remaining portion of a single rotation of this cylinder the stud or
friction roller on the arm 8 runs in that part of the groove of the cam 21, which
is concentric with the shaft 68, so that no outward or inward movement of the
blade shaft 1 occurs, and though the shaft and blade continue their rotation the
edge of the latter will not be protruded beyond the periphery of the cylinder. Thus
the edge of the constantly rotating folding blade will travel in the path indicated
by the dotted lines of Fig. 10, and be turned outward and projected once to co-
operate with the folding rollers 61, 62, and be rotated inside the cylinder three
times during each single rotation of the same.
This construction of apparatus for actuating the folding blade is in like manuer
adapted to be used when a simple revolving frame work, supporting the shaft 9, is
employed in the place of the cylinder 30, in using which the paper is directed in
front of or before the folding rollers 61, 62, and does not pass on to the cylinder.
The sheet conducting mechanism interposed between the primary and secondary
sheet manipulating apparatus for conveying the sheets from one to the other
consists of sets of tapes 22 and guards 18. These tapes are stretched over a
roller 23 in the grooves of which the switches 70 of the cylinder 20 play to a
roller 24 near the cylinder 30, in the grooves of which enter the ends of conductors
25 which extend to a point near the periphery of the cylinder 30. These tapes
are driven through the wheels 92, 59, from the cylinder 20, and thus run with a
like surface-speed. The guards 18 are supported above and about parallel with
said tapes, and extend from grooves in the roller 81 to a point over the cylinder 30.
It has been common in applying a longitudinal line of paste to one or more sheets,
which are to be united as one product, to employ a disc alternately moved into and
out of the plane in which the sheets travel, or to depress the proper sheets or a
portion of the web into contact with a paste disc situated in a plane below that in
which the sheets travel.
In the present improvements the cylinder is supplied with a pasting
mechanism, the pasting disc 66 of which runs in a paste vat 67, and is
constantly supported by means of the fixed bearings of its shaft and vat in one
operative position with respect to the surface of the cylinder. This disc 66 is
constantly driven by a pulley 88 on its shaft, which receives motion from another
pulley, as 79, fixed on any one of the moving shafts of the machine (see Fig. 3).
This pasting disc and its trough are so attached to the frame work that they may
be readily removed, which removal is effected when it is desired that the carrier
shall collect sheets without applying paste thereto, and also to preserve the
condition of the pasting mechanism when not in use.
The cylinder 20 is grooved circumferentially at the point 2, coinciding with the
position of this paste disc 66, so that when it is not in contact with a sheet it will
be nonoperative and will not smear the cylinder.
By means of this arrangement of the pasting mechanism a longitudinal line of
paste may be applied to all but the last of any number of sheets carried singly on
to a collecting cylinder, and thus have their contact surfaces united to form them
into a single mass or body; for the reason that while the first sheet receives the

page_text: lines of paste and thus adheres to the second (if two is the number to be collected),.
which two thus united are discharged by the switches, as in Fig. 4, the second.
sheet does not reach the pasting disc which thus rotates ineffectively as just
described; but if the cylinder 20 collects three or more sheets (as it may by causing
the cam wheel, 97 to make an appropriate number of rotations to each one of the
cylinders), then the first sheet will be pasted as will the second, third, and every
sheet passing round its surface, except the last, which is discharged before reaching,
the pasting disc, as before described, with the preceding ones underlying it.
The operation of the parts for collecting pasting and folding the sheets of printed
paper is as follows, viz.-The sheets from the web-press are conducted to the
cylinder 20 by means of the tapes 51, 52, and the first incoming sheet is seized by
the grippers 95, and held upon the cylinders during nearly a whole revolution of
the same, the switches 70 being rocked as in Fig. 5, and the gripper discharging
cam 64 rocked, as in Fig. 7, during this movement of the cylinder. As this first
sheet runs in contact with the pasting disc 66 it receives a line of paste on its outer
surface, upon which sheet as it reaches the entrance channel the next incoming
sheet is laid, so that the front edges of both sheets are seized and held upon the
carrier by the grippers 95, the two thus being laid one upon the other as the
cylinder rotates and becoming united by the line of paste. At this time the
switches 70 will have been rocked into the position of Fig. 6, and the discharging
cam 64 will have been rocked so as to intercept the rocking arm of and open the.
grippers 95, as in Fig. 8, and the two sheets thus released will be delivered through
the discharging channel on to the sheet conducting tapes 22, which deliver them on
to the cylinder 30, where they are seized by the grippers 33, which are operated
by their spiral spring in connection with the fixed cam 34. Thus held, the sheets
are carried around upon the surface of the cylinder 30, as in Fig. 5, and released at
the proper time for their middle portion to be acted upon by the rotating folding
blade 6, as in Figures 4 and 6, by the action of which blade the attached sheets
are doubled into the nip of the rollers 61, 62, from whence they emerge in a once
folded condition.
In this operation it is to be observed that two sheets are gathered together or
accumulated one upon the other, so that they occupy but one half of their original
space in the direction of their travel, and that they are discharged as one and
conducted to the secondary mechanism with the same speed at which they were
manipulated by the primary. When they reach and are seized by the secondary
they are forced to take up its speed which is much less than the primary, and are
thus caused to move more slowly as they are manipulated by that mechanism, and
that consequently they occupy a considerable time relatively in moving out of the
conducting channel. During this movement of them at slow speed the first one of
the next pair of sheets is passing around the primary cylinder, and when the second
sheet is laid upon it at the second rotation of the cylinder and passes into the
channel the first pair of sheets will have been disposed of and the channel freed
for their reception.
In the rapid manipulation of large sheets of paper it has been found by experience
that only such as are of a high grade or quality can be driven or pushed from one
mechanism to another, and even these are liable to have their leading ends curled
or buckled up, thereby clogging the apparatus. In order therefore to deliver such
large sheets smoothly and surely from the collecting to the folding apparatus,
particularly such as are of a low quality of paper, without their being liable to
buckle up, sheet forwarding rollers 26, 27, are provided at a point between the
cylinders 20, 30, and which are driven at the same speed as the cylinder 20 by
means of the pinion 32 on the shaft of the latter which meshes with the wheel 99.
The shaft of the roller 26 (which roller may be driven by surface contact with its
companion or in any other suitable manner) is hung in arms projecting from a rock
shaft 28 which is moved by a rocking arm 29, (Figures 1 and 2,) actuated by a cam
groove 31 formed on the inner face of the wheel 99. This roller is thus moved
intermittently into and out of contact with the roller 27, (Figures 4 and 5,) and is

page_text: cut away so as to span the guards 18 when in contact with the roller 27 (see Fig. 2).
The roller 26 is moved into operative contact with its companion 27 so that when
the pair of sheets emerging from the primary mechanism reaches them they are
nipped and positively driven onward by said rollers, which continue to act until
the leading end of the sheet is about seized by the secondary mechanism, when the
roller 26 is raised and the sheets left wholly within the control of the secondary
mechanism, which carries them onward at its slow speed and manipulates them as
before described.
The primary sheet manipulating apparatus may be constructed as shewn in
Fig. 12, where the cylinder 20 (which may or not have grippers) is illustrated to
be a cylinder provided with devices adapting it to aid in collecting two sheets so
that the same are brought together and discharged in a single body. With this
cylinder is combined a secondary sheet manipulating apparatus, constructed as
herein before described but operated at one half the speed of the primary by means
of the toothed wheels 38, 39, which connect the wheel 72 and pinion 93. This
cylinder 20 is nearly embraced by the series of tapes 52 which, leading from the web
cutting cylinders in like manner as before explained, pass over the roller 85, around
the cylinder 20, and over the roller 86, and return around the roller (see Fig. 12)
placed near the cylinder 30, the rollers being driven from the toothed wheel 96 by
gearing in like.manner as are the rollers 81, 82, 8+- Their companion tapes 55
lead from the cutting cylinders of the web printing machine as do the tapes 51 and
pass over the roller 85, thence through grooves in a nipping roller 87, and return
over pulleys 40 located over the cylinder 30. The tapes 52, 55, are thus so disposed
that they form the conducting channel between the cylinders 20 and 30.
The nipping roller 87 is provided to nip the sheets discharged from the carrier
and insure their onward movement.
In this construction of the primary apparatus the entrance channel is formed by
the switches 100, which are vibrated through the rod 101 from a cam 102 mounted
on the shaft 68 of the cylinder 30. These switches direct the first incoming sheet
round the roller 85 and into the position Fig. 12, and direct the second sheet over
their upper surface into the bite of the rollers 86, 87. The first sheet is thus
guided around the cylinder 20 and is directed over the roller 86 by the fixed guide
103, where it meets the second sheet and the two are guided together between the
rollers 86, 87. The switch may be so timed as to collect two sheets or any multiple
thereof before discharging the same. In this operation the sheets are manipulated
and caused to occupy one half of their former space in the direction of their travel
as they leave the primary cylinder in substantially the same manner as before
described, and they are delivered to the secondary apparatus, which is the same
structure herein before described, and thus has time to manipulate them at a reduced
speed, as has been set forth.
It is obvious from the foregoing description that the collecting mechanism of the
primary may, when arranged to deliver its product to the secondary, be adjusted to
collect not only two sheets but any multiple thereof.
A folding mechanism constructed and operated as herein shewn and described
may obviously be connected directly with a web printing machine and deliver its
once folded products from folding rollers 61, 62, directly onto a piling-table to a
vibrating or other flying apparatus, or to a folding mechanism of any description.

Fig. 26, Sheet IV., shews the gripper shaft in detail, with rocking arms on each end
to be operated by the two gripper cams; and Fig. 2, Sheet VIII., represents a
further modification of the Invention.
These modifications consist in the arrangement of an auxiliary cam for actuating
the grippers of the cylinder in proper time to release the sheet supported upon the
cylinder, also in an arrangement of intermediate gear for actuating the folding
blade, and of a cam for projecting this blade at the proper time, as well as of other
combinations of parts, all of which will be more particularly hereinafter pointed
out and described.
In all these modifications the sheets are received in succession from tapes 37, 38,
to which they are delivered by the cutting-cylinders of the web printing machine,
and which tapes lead the sheets onto the cylinder 30. The upper tapes 37 passing
in contact with the upper surface of the cylinder 30 are returned over the upper
of a pair of folding rollers 35, 36, which geared together by toothed wheels 63, 64,
are driven from a toothed wheel 73, Fig. 3, fast to one end of the cylinder 30, and
thus revolve in unison with said cylinder, and drive the tapes 37 with a like speed.
The lower tapes 38 run parallel with the tapes 37 pass over a roller 39 pass in
contact with a delivery cylinder 40, and return under pulleys 41 toward the
aforesaid cutting-cylinders.
The cylinder 40 is driven by a toothed wheel 71 which gears with the wheel 73,
and is thus moved in unison with the cylinder 40, thereby imparting the same
surface speed to the tapes 38, which the tapes 37 have and hence causing the two
sets of tapes to feed the sheets uniformly.
The space between the rollers 39 and the surface of the cylinder 30 is spanned
by guards 16, which insure the proper direction and even passage to the sheets.
This cylinder 30 is made larger than the cutting cylinders, and as it runs turn for
turn with them it has a greater surface speed in order that the sheets shall be
separated a distance apart as is fully described in the above mentioned Patents:
This cylinder 30 is recessed at one point to accommodate the grippers 14, whose
shaft is hung in the heads of the cylinder and provided with a spring-seated
arm 34 and a rocking arm 15 at one end, and with a rocking arm 1 at the opposite

page_text: end (see Figures 1 and 26). Its rocking arm 15 engages, and is operated by a
cam 70 fixed to the side frame in such a position that said grippers will be opened
to receive and closed to seize the leading edge of an incomming sheet, and thus
hold the same onto the cylinder, and also open at the proper time and extent to
release sheets to be discharged at the switches 18. Its rocking arm 1 engages
with and is operated by the auxiliary cam 3 supported on the face of the blade
shaft projecting cam 59, whereby the said grippers are opened at the proper time
to release a sheet or sheets when the same are to be folded. Both of these
operations will be more fully described hereafter.
The cylinder 30 supports also a folding mechanism, the folding blade whereof is
provided with means whereby it is rotated continuously upon its own axis, and is
turned outward many times during each rotation of its carrying-cylinder 30, but
always within the periphery of said cylinder, except at the proper time when it is
to cooperate with the stationary folding rollers when it is protruded beyond the
periphery of the cylinder end entered between said rollers. To this end this
folding blade 5 projects from a shaft 32 that is mounted in arms 11, 12, fast upon
a rock shaft 33, the latter being mounted in the heads 74, 75, of the cylinder, Fig. 8.
The blade shaft 32 has a pinion 10 fast upon its end, which gears with an inter-
mediate toothed wheel 9 turning freely upon the rock shaft 33. This intermediate 9
is made wide enough to gear with an intermediate-toothed wheel 8, which
revolving on a stud projecting beyond the head 74 of the cylinder, gears with a
fixed internal toothed wheel 68 secured to the side frame. By this arrangement
the pinion 10 on the folding blade shaft is kept outside of the wheel 68, and is free
to be moved in and out without coming in contact with it. The rock shaft 33.
has a rocking arm 13, the stud or roller on the end of which runs in the groove of
a folding blade projecting cam 59, Figures 2, 4, and 5. This cam 59 is hung on the
shaft 31 of the cylinder 30, and provided with means for causing it to revolve
independently of said cylinder, and with means for causing it to revolve in unison
with said cylinder, which means and modes of operation will be hereinafter
explained. It is also provided with means for securing it in a stationary position,
with respect to said cylinder which consists of a screw pin 76, Fig. 5, passing
through the side frame and entering a socket in said cam wheel. This stationary
adjustment of said cam wheel is in its proper position when the mechanisms are
arranged to fold each sheet received upon the cylinder 30, which part of the
operation of the apparatus is now to be described.
As the cylinder 30 rotates it carries with it the folding blade 5, the shafts 32, 33,
the pinion 10 and the intermediate 9, 8, and as the intermediate 8 is made to
rotate by running in the wheel 68, it causes the folding blade 5 to receive a like
motion through the intermediate 9 and pinion 10. Thus the folding blade 5 will
be caused to rotate upon its axis as many times during each revolution of the
cylinder 30, as the teeth of the pinion 10 are proportioned to those of the wheel 68.
In the present instance this proportion is as one to four, and hence said blade will
make four rotations during each rotation of the cylinder 30. As the cylinder 30
rotates to produce these rotations of the blade the rocking arm 13 traversing the
lower part of the groove of the cam 59 (now stationary until its greatest depression
is reached) causes the blade shaft 32 to be projected outward from the centre of
the cylinder 30, and as the pinion 10 partakes of this same movement, and is kept
in constant gear with the intermediate 9 by reason of its carrying arms 11 and 12
being fixed on the shaft of said intermediate, it follows that the said blade will be
given the compound movements of rotation and outward projection, and will thus
be protruded through an opening in the cylinder, and it is so timed as to be turned
or entered between the folding rollers 35, 36. As the motions proceed the folding
blade continuously rotating will be withdrawn from said folding rollers by reasou
of its rotation, and the inward movement given to its shaft 32 by the action of the
cam 59 on the rocking arm 13, while the latter is traversing the low part of the
groove in cam 59 from the point of its greatest depression to that of its least
depression, or where it joins the concentric portion.

page_text: When the arm 13 has entered and is traversing the concentric part of the groove
in the cam 59, the blade 5 and its shaft 32 and pinion 10 will have reached the
extent of their inward movement, and the said devices are retained at such a point
within the cylinder that though the folding blade continues to rotate, and its edge
is turned outward three more times during one rotation of the cylinder, and toward
the periphery thereof said blade will not be projected beyond said periphery. The
edge of the folding blade is thus caused to describe the path indicated by the dotted
lines in Fig. 7, and hence may be advantageously employed with a cylinder
adapted to support upon its surface the sheets which are to be manipulated.
A sheet emerging from the conducting tapes 37, 38, will be guided on to the
cylinder 30, and seized and held thercon by the grippers 14, which grippers are
opened at the proper point to receive the sheet by the cam 70, and closed by the
spring seated arm 34 to seize the same when the rocking arm passes off said cam.
Thus held, the sheet will be carried around with the cylinder, its middle portion
overlying the point occupied by the folding blade 5, as this folding blade constantly
rotated by the action of the fixed wheel 68, the intermediates 9 and 8 and pinion 10
approaches the folding rollers 36, 35, the rocking arm 13 will enter and traverse the
first half of the low part of the groove of the cam 59, thereby causing the shaft 32
and the folding blade it carries to be gradually rocked outward. As the rotation of
the blade continues it brings the edge of the blade into contact with the sheet, thus
causing said blade to press the sheet outward, and to double it into the nip of the
folding rollers 30, 35, the edge of the said blade by its rotative and outward
movements being carried over the curved surface of the roller 36, and between it
and the roller 35, as in Fig. 4.
The grippers 14 are simultaneously opened to release the sheet by contact of
their rocking arm 1 with the auxiliary cam 3, which stands in the position shewn
in Figure 4. The sheet thus entered between the rollers 36, 35, will at once be
seized by and fed outward between them in a folded condition, while the folding
blade 5, still continuing its rotation and being moved inwardly by the action of the
last half of the low part of the groove of the cam 59 upon its arm 13, will be with-
drawn from between said folding rollers, during which movement its edge will be
carried over the curved surface of the roller 35. As the movement of the leading
end of the sheet is reversed and it is drawn backward in passing through the
rollers 36, 35, it is prevented from hanging down by means of guards 50 which are
fixed on rods, so as to coincide with the curved surface of the cylinder 30. As the
cylinder continues to rotate the grippers 14 will seize a second sheet emerging from
the tapes 37, 38, which sheet will be folded by the blade 5 in like manner as was
the first sheet, but before said blade reaches its position for co-operation with the
folding rollers 36. 35, it will have made three complete rotations idly or in-
operatively within the periphery of the cylinder, for the reason that its shaft is
held in its innermost position while its actuating rocking arm 13 is traversing the
concentric part of the groove of the cam 59, as before explained.
The cylinder 30 is also furnished with mechanisms whereby many sheets may be
collected upon its surface, and delivered therefrom in a single body as will now be
described (see Figures 9 and 10).
'
An ordinary collecting or accumulating cylinder is provided with an entrance
channel for the sheets, a delivering channel for the same means for directing
successive sheets upon its surface, and there retaining them so that they will collect
one upon another, and with means for stripping the same therefrom in a single
mass.
In the present instance the entrance channel is constituted by the tapes 37, and
thic directing guards 16, and the delivering channel by the delivering cylinder 40,
and a set of stripping switches 18.
The grippers 14 aided by the tapes 42, the tails of the stationary guards 16
which are concentric with the cylinder, and the faces of the switches 18 retain the
sheets upon the cylinder, and said switches operate to strip the same therefrom, all
of which will presently be made more clear.

page_text: In order that the folding blade shall be rendered inoperative at the folding
rollers 36, 35, through which it would otherwise fold the sheets as before described,
and to adjust the apparatus so as to perform the collecting operation only, its
projecting cam 59 is released from the hold of the screw pin 76, which is removed
as shewn in Figure 10. Said cam is then partially rotated on its shaft so that
the rocking arm 13 of the folding blade shaft shall be held in that part of its
groove which is concentric with the cylinder 30, whereby the folding blade 5, its
shaft 32, and pinion 10, will be held within the periphery of the cylinder, in which
position said cam 50 is fixed to the shaft 31 by the set screw 2, Figures 5 and 10,
and will rotate continuously with the cylinder 30. With the cam 59 thus held
the rocking arm 13 will receive no motion therefrom, and though the folding blade
will continue to rotate, its movements will be wholly rotative, and it will not be
projected beyond the periphery of the cylinder. As the auxiliary cam 3 will
revolve with the cam 59 and cylinder 30, it will of course have no effect upon the.
grippers 14, so that the grippers will be operated solely by the main gripper
cam 70. The switches 18 are mounted upon a shaft 4 (see Figures 1, 2, 9), which
is rocked at proper intervals by means of a rocking arm and a rod 7, the stud
projecting from the side of which latter runs in the groove of a cam wheel 66.
The front faces of the switches are curved so as to coincide with the periphery
of the cylinder 30 when in the position shewn in Figure 4, and their rear curved
faces in like manner coincide with the periphery of the delivering cylinder 40
when in the position of Fig. 9, the said cylinders being grooved to permit this
movement of them.
The cam wheel 66 is mounted upon one end of a shaft 80, which at its opposito
end carries a toothed wheel 54 that is geared to a toothed wheel 57 (the latter
being removed as in Fig. 4 when each sheet is to be folded, as in the operation
herein before described), which is on a short shaft projecting through the side frame
that carries on its other end an intermediate toothed wheel 55, which gears with a
pinion 56 fast on the shaft 31 of the cylinder 30 (see Fig. 10). As the pinion 56
has one tooth to every two teeth of the wheel 55, and.the wheel 57 on the same
shaft has one tooth to every two teeth of the wheel 54, it follows that the latter
will make one rotation to every four of the cylinder 30, and hence will rock the
switches 18 into the position shown in Fig. 9 at every such fourth revolution, while
the shape of the cam 66 will cause them to stand as in Fig. 4, during the inter-
vening rotations of said cylinder.
A fly frame 27 whose shaft 87 is hung in bearings fixed on the base plate is
vibrated at proper intervals by the following means. It is held up so that its
ends enter the grooves in the delivering cylinder by a cam 65 on the shaft 80
which bears against a stud 84 on a red 85 that connects with one end of a T head
86 on its shaft 87, and when the highest part of this cam passes said stud a spring
seated rod 88 forces the fly frame downward. A set of tapes 42 driven by the
receiving cylinder 40 are stretched over the same pass down before the fly frame
when in its upright position and return around pulleys 26, 25, running for a short
distance in contact with the cylinder 30.
By the arrangement just described four sheets are collected on the cylinder to
be delivered at one time to the fly frame to be flown in the usual manner.
If it is desired to collect more than four sheets the wheel 54 will be properly
proportioned to the pinion 57.
4
In order to adjust the apparatus to collect two sheets, and fold or paste and fold the
two together (see Figures 12 to 15) the cam 59 is disconnected from the shaft 31
by removing the set screw 2. The toothed wheel 57 is then reversed on its shaft
so that it will be disconnected from the wheel 54 but will align with and gear
into the toothed wheel 58 (see Figure 12) which wheel is fixed to the back of the
cam 59 by means of fastening screws 49 as is seen in Fig. 15 and thus properly
connected and timed said cam 59 will be revolved with said wheel 58 and operate
as will presently be made clear. The rotation of tlie cylinder 30 will then through
its pinion 50 and the intermediate wlieels 55 and 57. cause the wheel 58 and the

page_text: cam wheel 59 now secured to the latter to rotate in the same direction that it
moves; but as the wheel 55 is twice the size of the pinion 56, as already described,
and as the wheels 57 and 58 are of equal size it follows that the cam 59 will make
but one turn to each two of said cylinder 30.
A pasting apparatus similar to that already described is now adjusted in place.
The apparatus thus adjusted will operate as follows. The successive sheets
delivered to the surface of cylinder 30 are each in turn seized at the point of their
entrance thereon by the grippers 14 and carried around with the cylinder. The
first sheet of a pair thus seized and held upon the cylinder makes a complete
revolution with it, but it is not folded because during this first revolution of the
cylinder 30 the depressed or working part of the cam 59 has been in the meantime
revolved by the gear wheels 56, 55, 54, 58, to a point directly opposite its normal
or working position (see Fig. 13). The auxiliary finger cam 3 on the cam 59 has
also been rotated to a point opposite its normal position, so that this first sheet is not
released until it nearly reaches the delivery cylinder 40 when the grippers are
opened by the cam 70 to receive the next incoming or second sheet, consequently
the first sheet is carried well into the nip of the tapes 42 which together with the
switches 18 and guides 16 conduct it around until it is caught by the tapes 37
where the second sheet is deposited upon it. The grippers 14 now close on the
two sheets and they are carried around until their heads nearly reach the. pasting
disc by which time the cain 59 will have completed its revolution so that the
auxiliary cam 3 will be in position to open the grippers at the point just indicated
(see Fig. 14). The depressed or working part of the folding cam has also now
arrived at its working position, so that the folding blade is now thrown outward
and the two overlying sheets just released by the grippers are doubled into the
folding rollers without their heads having reached the pasting disc on the tapes 42.
The first sheet in passing the pasting disc has a longitudinal line of paste laid
upon its central part by which it. will be caused to adhere to the second sheet
when the two are pressed together and passed through the folding rollers.
The folding blade projecting cam may be alternately moved into a position
where it will not cause the projection of said blade into co-operating position with
respect to the folding rollers 36, 35, as it passes the point occupied by them when the
cylinder 30 is carrying the first shect of a pair and into a position to project said blade
between the folding rollers, when the cylinder carries two associated sheets which
are to be doubled into the nip of said rollers by other means than is hereinbefore
described. Thus said cam may be reciprocated toward and from the folding rollers as
in Figures 16 to 19, or be reciprocated toward and from the cylinder head laterally
into and out of engagement with the rock arm attached to the folding blade shaft
as in Figures 20 to 22 inclusive.
In Figures 16 to 19 a reciprocating cam 90 is shewn as provided with suitable
guide ledges with bevilled sides (see Figures 16, 17), adapted to run in corre-
sponding guides formed by the bevilled side pieces 92, 92, attached to the side
frame. It is provided with a stud 93 which runs in the groove of a cam wheel 94
where it is moved to and from the folding rollers 36, 35, a recess 95 cut through
its centre admitting this movement of it. It is also provided with an elliptical
groove 91, the ends of which are true semicircles in which runs the rocking arin 13
of the folding blade shaft.
The cam wheel 94 is caused to make one rotation to each two of the cylinder 30
by the following means -The said cam wheel is fast upon one end of a short shaft
which carries at the opposite end a toothed wheel 101 which meshes with a pinion
102 fast upon the end of the shaft 31 of the cylinder 30, and as the number of
teeth of the pinion 102 are to those of the wheel 101 as one is to two, it follows
that said wheel 101 and consequently the cam wheel 94 driving the reciprocating
cam 90 will make one rotation while the cylinder is making two rotations. The
said cam wheel 94 thus carries the reciprocating cam 90 into the position shown in
Fig. 18 during that rotation made by the cylinder 30 iu receiving the first sheet
of a pair when the folding operation is to be suspended and into the position shewn

page_text: in Fig. 19, during that rotation of the cylinder when a second sheet is received and
collected upon the first when the folding operation is to be effected.
The operation of the apparatus as thus modified will now be described.
As this modification of the apparatus is not designed to deliver sheets flat, the
fly 27, the tapes leading thereto, and the switches 18 will of course be dispensed
with, though tapes 97 running over pulleys 25, 96, and bearing against the face of
the cylinder 30 from a point just in advance of the pasting disc to a point near the
tails of the guards 16, and operating as do the tapes 42 with the cylinder 30, will
be required. The arm 13 on the end of the shaft 33 for moving the folding blade
in and out of the cylinder points in the opposite direction to those previously
illustrated herein, which causes the groove in the folding cam in which this arm
runs to assume a different shape from the former one.
As the first sheet of a pair is received and carried around upon the cylinder 30
the reciprocating cam 90 will stand as in Fig. 18, so that the groove in its upper
end will be concentric with the periphery of the cylinder, and consequently the end
of the rocking arm 13 which actuates the folding blade shaft will traverse said
groove without being moved thereby, thus retaining the shaft 32 of said blade in
its innermost position, but when the cylinder 30 has so far rotated that the leading
end of the first sheet is approaching the point of reception of the second sheet the
cam wheel 94 will have so far rotated as to have caused the stud 93 to pass out of
the low part.of its groove 94 and into the high part thereof, thus reciprocating the
cam 90 upward or into its forward position, as in Fig. 19, when the groove 91 of
the folding cam 90 in its lower end will be concentric with the periphery of the
cylinder 30, and the groove in its upper end will stand in an excentric position
with relation to said periphery where it remains during about five eighths () of
the rotation of the wheel 94, or while the cylinder 30 makes about one and one
quarter (1) rotations. The end of the rocking arm 13 following this groove
91 remains in an unchanged position with respect to its movement for projecting
the blade shaft until the cylinder has so far rotated as to carry the second sheet
upon the first and bring the middle portion of the collected pair of sheets near to
the part occupied by the folding rollers 36, 35. Now as the folding blade
approaches this point the end of the rocking arm 13 following the upper end of the
cam groove 91 (then its excentric position) is forced outward, thus projecting
the blade shaft 32 and causing the folding blade to double the sheets into the nip
of the folding rollers, and is drawn inwards by the sliding cam 90, thus withdrawing
said blade shaft and folding blade, causing a folding operation precisely like that
first herein before described. The cam 90 does not again change its position until
the folding blade again approaches the folding rollers, when it is quickly moved into.
the position shewn in Fig. 18 and the operation is repeated.
Another construction of reciprocating_cam for folding two sheets associated
together to form one product is shewn in Figures 20 to 22 inclusive. It is in form
like those illustrated in Figures 1 to 11, and is marked 100 for convenience of
reference. It has a cam groove 98 the lower part of which is about one fourth its
whole extent and carries upon its face the auxiliary gripper cam 3. This cam 100
is fixed to the inner ends of rods 103, 104, which slide in bearings through the side
frame, the connecting cross bar of which has an arm which runs in the groove 106
of a cam 107 mounted upon a stud secured to the side frame. This cam 107 is
fast to a toothed wheel 108, which is driven from a pinion 109 fast on the end of
the shaft 31 of the cylinder 30, and as the pinion 109 is but one half the size of
the wheel 108 the cam 107 is caused to make but one rotation to each two of the
cylinder 30. The rods 103, 104, are long enough; and the throw of the cam 107
is such that the cam 100 will be moved to and from the end of the cylinder 30 so
as to engage with and disengage from the end of the rocking arm 13 which actuates
the rock shaft 33 that supports the folding blade shaft, which rocking arm when
disengaged from the cam 100 is held in the position shown in Fig. 21 by a spring
seated rod 99 that is attached to an arm projecting from said shaft 33 inside of the
cylinder for this purpose. Thus held the end of the rocking arm is in position to

page_text: .
This cam
enter the high part of the groove in the cam 100 at any point thereof.
100 when in its innermost position acts to move the rocking arm 13 inward to
throw the folding blade shaft outward, and thus project the said blade between the
folding rollers 36, 35, and reverse the movements to withdraw the said blade.
Said folding cam is moved to and from the ends of the folding rollers and cylinder
at certain periods of the rotation of said cylinder, as will be best understood from a
description of the operation of this modified apparatus. In such description the
mechanisms which (marked the same) are like those herein before described, are to
be understood as having the construction and mode of operation there set forth.
As the first sheet is received and carried around upon the cylinder 30 the cam
107 will have so rotated as to withdraw the cam 100 from engagement with the
rocking arm 13, which latter, together with the folding blade shaft, will under the
influence of the spring seated rod 99 stand in the position shown in Fig. 21 whereby
the folding blade 5 though constantly rotating being caused to so move within the
peripheral line of the cylinder will thus not cooperate with the folding rollers 36, 35,
to fold the said first sheet. Just after the cylinder has so far rotated as to have
received a second sheet upon the first sheet on its surface the cam 107 will have so
far rotated as to move the cam 100 inward to receive the end of the rocking arm 13
in the high or concentric part of its groove, following which groove, as the cylinder
continues to rotate, it will force said arm inward and move the blade shaft outward,
thus projecting the blade so that it will be moved into cooperation with the rollers
36, 35, and double the two sheets into the nip of the same, the outward movement
of the rocking arm 13 and consequent inward movements of the blade shaft and
blade, following in like manner as before described. As the cylinder continues to
rotate to receive the first sheet of a second pair the cam 107 will be rotated to
withdraw the cam 100 out of engagement with the rocking .arm 13 which will
again assume the position shown in Fig. 21, and the described operation be
repeated.
It is obvious that only that section of the cam 100 or the low part thereof which
constitutes the outer portion of the said fourth part of its cam groove need be
reciprocated in and out of position for engagement. with the rocking arm 13 and
-the cam 100 is to be considered herein as constructed in that manner or as hereto-
fore described.
To fold each sheet singly the pinion 109 may be removed and the cain 107
rotated until the cross bar 105 and cam 100 take their innermost position
where they will constantly remain. This projection of a constantly rotating folding
blade without the periphery of its rotating cylinder at each second revolution
thereof to cooperate with folding rollers mounted in stationary bearings at a given
point relative to such cylinder may be accomplished by means of a stationary blade
shaft projecting cam if the proportion of the gearing which rotates the said folding
blade is such as to cause it to make three and one half (3) rotations to each
rotation of its cylinder, which construction is shewn in Figures 23 to 25. The
blade projecting cam therein designated 110 like the similar cam 59 is fixed
stationary by being fastened to the frame, its operation in projecting the blade
shaft being the same as said cam 59 and effected at each rotation of the cylinder 30.
But while this blade-shaft is projected at the first rotation of the cylinder when it
is carrying the first sheet of a pair the rotation of the blade will be so timed by the.
gearing that said blade will be pointed inward when passing the point occupied by
the folding rollers 36, 35, and will hence pass by them without affecting the sheet,
and as the blade shaft is drawn inward by the action of said can before the blade
rotates far enough to touch the sheet it follows that said first sheet will be carried
around upon the cylinder to receive the second sheet upon it, and that the said
blade will rotate idly in its innermost position until two sheets have been collected
one on the other upon the cylinder and said blade shaft is again projected at the
folding rollers. At this second projection of its shaft the blade will be making that
part of its rotation in which the blade is pointed outward, and will consequently
double the two sheets into the nip of the rollers 36, 35.

page_text: The folding mechanism shewn in connection with the primary sheet manipulating
mechanism, may, when acting to fold sheets which are not to be accumulated, have
such sheets fed directly between its carrier and the folding rollers 36, 35, in which
case the carrier need not be constructed as a cylinder 30 but may be a framework
capable of supporting the shafts 32, 33.
The folded sheets converging from the rollers 36, 35, may be delivered in their
once folded condition, or they may be carried to a secondary folding machine and
be again folded one or more times on lines parallel with their first fold, at right
angles thereto, or both, by folding mechanism such as hereafter shewn.
Herein are shown two forms of a secondary sheet manipulating mechanism, one
of which is a folding machine constructed in like manner as is that of the secondary
sheet manipulating apparatus above described. It consists of a cylinder 20 (see
Figs. 4 and 11, Sheets V. and IV.) provided with grippers 17, the rocking arm 46 of
which is operated by a cam 45 and a rotating folding blade 6 mounted fast upon a
shaft 19 which turns in its carrying arms 67, 81, which are secured to a rocking
shaft 82 that is hung in the heads of cylinder 20. These arms 67, 81, and the
shaft 19 they carry are rocked by means of a rocking arm 69 running in a grooved
stationary cam 47, the said shaft 19 being rotated by means of a pinion 78 fixed
upon its end that gears with an intermediate 79 which turning freely on the shaft
82 remains constantly geared with a stationary driving toothed wheel 83 that is
fastened to the framework, in this instance being attached to the cam 47. This
blade 6 cooperates with stationary folding rollers 28, 29, which are geared together
by wheels 60, G1, and rotated by means of a toothed wheel 62 fixed to one end of
the cylinder 20. As the intermediate wheel 79 and arms 67, 81, supporting the
blade shaft 19 to which the pinion 83 is fixed are hung upon the same shaft 82, it
follows that said pinion will remain in gear with and be constantly driven by the
said intermediate, whatever may be the degree to which the blade shaft is projected
by the cam 47. Thus, at each rotation of the cylinder 20 the folding blade will be
rotated a number of times, according to the proportion its pinion 78 has to its driver
83, and by means of the arm 69, and the cam 47 will during one of these rotations
have its carrying shaft moved outward and inward so that the blade will enter
between the folding rollers 28, 29, and be withdrawn therefrom in performing the
operation of folding.
The cylinder 20 is made one half the size of the cylinder 30 for the reason that
the sheets manipulated by it having been once folded are reduced to one half their
original length. It is driven from the toothed wheel 53 on the shaft 31 of the
cylinder 30 by means of the wheels 52, 51, and though making equal turns with
said cylinder 30 it runs with but one half its surface speed. The sheets from the
folding rollers 36, 35, are directed to its grippers by means of endless tapes 43
which run from the folding roller 35 to a roller 44, above which tapes are conductors
77 which keep the sheets from flying upward, while a set of guards span the space
between the roller 44 and the cylinder 20.
The once-folded sheets emerging from the rollers 36, 35, may be conveyed to a
secondary mechanism constructed as is shewn in Fig. 27, Sheet VIII. They are
directed by a conducting mechanism formed by the tapes 43.and conductors 77 to
the nip of a pair of forwarding rollers 111, 112, which are geared together to run
in unision and driven at or about one half the surface speed of the cylinder 30 by
means of a toothed wheel 125 that is actuated by the toothed wheel 53 on the
shaft 31 through a train of wheels 126, 127, the said toothed wheel 125 being
twice the diameter of the roller 111. As the wheels 53 and 125 run tooth for tooth
and consequently at the same surface speed it follows that the roller 111 of one
half the size of said wheel 125 will run at one half its surface speed as well as that
of the cylinder 30.
The forwarding rollers 111, 112, discharge the folded sheets to two subsidiary
folding machines of the well known vibrating type, wherein a folding blade as 119
or 120 is vibrated at suitable intervals to double sheets beneath it into the nip of

page_text: pairs of folding rollers as 121 or 122, which, rotated in unision, carry the sheets
between them and deliver them in a now twice folded condition.
In this arrangement sheet, conveying tapes 117, 118, lead from the rollers 112,
114, to the lower subsidiary folding machine, and similar tapes 123, 124, lead from
the rollers 111, 113, to the upper subsidiary folding machine. Sheet directing
switches 115 are also provided, which switches 115 are so vibrated by a cam groove
116 with which the toothed wheel 55 is provided on its outside face for the purpose
that their points are alternately moved from the grooves in the rollers 111 into
those in the roller 112 and vice versa, thus standing in the grooves of roller 111,
as shewn while one sheet is passing through the rollers 111, 112, and 112, 114,
which sheet will thus be directed into the tapes 117, 118, the former aided by the
guards 128 carrying it out against a gauge 129 where it lies over the folding
rollers 122 and under the folding blade 120. This blade descends at the proper
time and doubles the sheet into the nip of said folding rollers from which it emerges
folded a second time at right angles to its first fold. As soon as this first sheet
passes their points the switches will be vibrated into the groove of the roller 112
sons to direct the second sheet into the tapes 123, 124, which lead to the upper
subsidiary folding machine between the rollers 121, of which the blade 119 will
double said sheet which will thus be folded in like manner as was' the first.
The construction of these vibrating folding devices is well understood, and is
described in Patents above referred to.
Under some circumstances it may be desirable to use a rotary secondary
folding mechanism in place of the vibrating secondary folding mechanism just
referred to. This rotary secondary folding apparatus may be so arranged as to
fold in a transverse direction either single sheets or two or more sheets as they
leave the primary folder.
This arrangement of secondary folder in combination with the primary folder is
shewn in Sheets IX., X., and XI. of the Drawings, in which Fig. 1, Sheet IX. is a
plan view; Fig. 2, Sheet X., is an end elevation; Fig. 3, Sheet IX., is a longitudinal
sectional elevation through the lines a, a, Fig 1, and shows the folding blade in the
folding cylinder in the act of folding two collected sheets.
Fig. 4, Sheet IX., is an end view of the folding cylinder with the frame work
removed to show the manner of operating the fingers and driving the rollers.
Fig. 5 shews the operation of the folding blades of the cylinder when collecting
two sheets.
Fig. 6 shews the operation of the same blade when folding each sheet singly and
the duplicate blade rotating mechanism for effecting the same.
Fig. 7, Sheet XI., shows a folding blade having one of the blades removed.
Figures 8, 9, 10, 11, show the different positions of a single blade when folding at
each second revolution.
Figures 12, 13, show a double edged folding blade as when folding at each
revolution.
. Fig. 14 shows the guard around the path of the folding blade cross-head.
Fig. 15 is a modification showing, how two sheets may be collected together and
one of them receive a longitudinal line of paste while on their way to the folding
cylinder.
Fig. 16 is a modification showing how two sheets may be collected together and
one of them receive a transverse line of paste while on their way to the folding
cylinder. The printed sheets of paper are brought from the cutting cylinders 1, 2,
to the primary folding cylinder by the tapes 12, 13, in the usual manner.
In the present instance however the tapes 12 are prolonged and made to pass
over a portion of the folding cylinder 5, between the folding rollers 21, 22, and
thence through the secondary sheet, folding mechanisms slightly above the
folding rollers 23, 24, and return over pulleys 25, 26, to the cutting cylinder 1.
The cylinder 5 is provided with another set of tapes 28 which are stretched from
a roller 29, extend partially around the cylinder 5, and return over the roller 19.

page_text: The cylinder 5 is provided with a set of fingers 31 to seize the sheets, which
fingers are opened by a finger cam 32, secured to the front side frame 7 and closed
by the spiral spring 33. The cylinder also carries a rotating single folding blade
34, which is driven in all respects in the manner described in Patent 3105 of One
thousand eight hundred and seventy five, except that this is a single edged folding
blade instead of a double edged one as is there described, or it may be actuated in
the manner shown in Sheets I. to III. of the present application. This cylinder is
also provided with a duplicate blade actuating mechanism (see Fig. 6), the
use of which will be explained in describing the folding of each sheet singly.
The pair of folling rollers 21, 22, are driven by the wheel 20 (see Fig. 4), gearing
into a pinion 39 upon the upper folding roller shaft which gears into another
pinion 40, upon the lower folding roller shaft, said folding rollers in connection with
the rotating folding blade formning the delivery by which the once folded sheets are
conducted to the secondary folding mechanisms.
The sheets of paper are severed from the continuous web in the usual
manner.
For collecting two sheets and folding them together, this mechanism operates as
follows:-
A sheet delivered upon the folding cylinder by the tapes 12, 13, is seized by the
fingers 31 and carried around until its leading edge is about to enter between the
tapes 28 and the folding cylinder, when the fingers will commence to open to release
(see Fig. 5), and to be in readiness to seize the next incoming one. As the cylinder
continues to rotate, the sheet by its momentum is carried into the nip of the tapes
28 and so on around until it reaches the tapes 12, where it is joined and overlaid by
the next sheet just brought forward by the tapes 12, 13, and the two sheets are now
seized by the fingers and carried on around.
While the cylinder was carrying around the first sheet, the edge of the folding
blade in making its semi-rotation when passing the folding rollers was carried
inwards towards the centre of the cylinder, but now as the cylinder is making its
next rotation with the two sheets, the folding blade in making its next semi-
rotation will be projected outwards and will enter the fold line of the two overlying
sheets into the bite of the folding rollers 21, 22, as in Fig. 3; and the two sheets
which will have been released by the fingers again opening will be conveyed off to
the secondary or cross folding mechanism.
If the two sheets are to be pasted together, pasting apparatus similar to that
already described may be employed.
For folding the sheets singly, duplicate folding blade cams 44, 45, and wheel 46 are
used to give the folding blade the semi-rotation necessary to bring it into operative
relation with the folding rollers 21, 22, at each revolution of the cylinder (see Fig. 6).
The operation in folding single sheets is precisely the same as in folding double slicets
except that as the folding blade will now by the action of the duplicate cams 4+,
45, be in operative position at each rotation of the folding cylinder it will fold cach
sheet into the nip of the folding rollers when passing by them. The secondary
folding mechanism consists of a rotating folding apparatus arranged to fold the
sheets parallel to the line of their travel in entering it.
This folding apparatus consists of a shaft 47 supporting the arms 48, 48, which
carry at one end a rotating double edged folding blade shaft 49, one blade of which
50 is removable. At the opposite end of the arms is hung a counter balancing
shaft 51, thus forming an open framework or carrier which is placed in co-operate
relation with a pair of folding rollers 23, 24. This carrier receives its motion from
the folding cylinder 5 by the wheel 53 driving the wheel 54 secured to the shaft
55, and a bevil wheel 56 on this shaft driving the bevil wheel 57 fixed to shaft 47
of the carrier. See Figures 1 and 6.
The proportion between the wheels 53 and 54 being the same as the proportion
between the bevil wheels 57 .and 56, the carrier shaft 47 is caused to run turn for.
turn with the folding cylinder 5.
The sheets delivered from the folding rollers 21, 22 are carried out over the

page_text: folding rollers 23, 24, by means of a set of tapes 58 that are stretched from the
lower folding roller 22 to the pulleys 59 so as to be just above the surface of the
folding rollers 23, 24, thus forming with the tapes 12 a sheet conducting channel
for carrying said sheets against the stops 60 in proper position to be folded between
said rollers 23, 24.
The folding rollers 23, 24, are mounted in stationary bearings in the framework
and geared together by the toothed wheels 61, 62, and are driven in unison and
at a proper speed by a wheel 63 on the overhanging end of the carrier shaft
47 which gears into a pinion 64 on the outer end of the shaft of the folding
roller 23.
.
At each rotation of its carrier, the shaft 49 of the double edged folding blade will
be caused to make a semi-rotation by means of the stationary cam 65, revolving
cam 66, and wheels 67, 68, for driving this latter cam as is fully described
in the Patent No. 3,105, of One thousand eight hundred and seventy five, before
referred to.
It is obvious that as the product of the primary folding mechanism is again
folded by the secondary mechanism that when the primary is folding, two collected
sheets at each second revolution, the secondary must also fold at each second
revolution, and when the primary is folding single sheets the secondary must be
arranged to do the same.
When folding pairs of collected sheets, one blade 50 of the double folding blade
may be removed as in Figures 3 and 7, and the ears to blade 59 to which it was
fastened, are turned around and fastened to the remaining to keep them out of the
way, and this remaining blade will be brought into cooperative relation with
the folding rollers at each second revolution of the carrier in the manner
heretofore described, with regard to the folding cylinder 5 when folding at each
second revolution so that each pair of collected sheets when delivered by the folding
rollers 21, 22, of the primary folding mechanism will be conducted out over the
folding rollers 23, 24, of the secondary mechanism and folded into their nip by the
operation of the single blade.
The positions the single folding blade assumes during the two rotations of the
carrier are illustrated by Figures 8, 9, 10, and 11, of which Fig. 8 shows the blade,
withdrawing after having folded a pair of sheets, Fig. 9 shows the position of the
blades when the carrier has advanced one half a rotation. Fig. 10 shows the
carrier completing its first rotation, and the blade passing the folding rollers and
rotating its edge inwardly. Fig. 11 shows the position of the blade when the
carrier has made the third half rotation, and at the completion of its second
rotation it will again fold a pair of sheets as in Fig. 8.
In folding single sheets, both folding blades 50, 68, see Fig. 12, are in position on
the folding blade shaft 49, and each on being delivered by the primary folding
rollers 21, 22, will be carried by the tapes 12, 58, until it reaches the stops 60,
when it will be forced into the nip of the folding rollers 23, 24, by the edge of one
or the other of the two folding blades as in Fig. 13, which in passing by the folding
rollers are semi-rotated by the motion given to the folding blade shaft 49 by the
stationary and revolving cams 65, 66.
To prevent the folding blade from being turned accidentally while passing around
out of contact of its stationary and revolving cams 65, 66, a curved guard 70, see
Fig. 14, is secured to the framework so as to just encircle the path of the friction
rollers on the cross head of the blade shaft.
This guard is in fact a continuation around of the stationary blade cam 65, and of
course the blade cannot turn except when passing the recess in that cam at the
folding rollers.
The devices shewn in Figures 15, 16, represent modifications of the operations of
collecting, pasting, and folding two sheets, and consists in collecting two sheets, one
on the other on their way from the cutting cylinders to the delivery mechanism, by
switching off the first sheet into a longer path than the second one, and bringing
the two together as they reach the folding cylinder as is described in Patent to

page_text: William Conquest, No. 4,645, of One thousand eight hundred and seventy six. To
accomplish this the tapes 12, 13, are stretched from the rollers 14, 15, near the
cutting cylinders up between the sheet breaking rollers 71, 72, where they separate,
the set 13 returning around the roller 16 to the roller 15, while the set 12 runs
up over the turning cylinder 73 and down between the rollers 74, 75, from which
it passes to the periphery of the folding cylinder 5 as before.
A third set of tapes 76 is stretched froni the roller 77 over the turning cylinder 73,
and down around the roller 75 to the roller 77, and this set in connection with
the tapes 12 forms a sheet conductor for the first sheet during its longer travel.
The upper side of the space between the rollers 72, 74, is occupied by the fixed
guide 78 and a switch 79, which in connection with the tapes 13 and the fixed
guide 27 on the lower side form a direct sheet conductor to the folding cylinder.
The points of the switch 70 are turned- towards the sheet breaking rollers 71, 72,
its office being to direct the sheets into the longer and the shorter paths of travel
alternately; and it is operated by a pinion 80 on the folding cylinder shaft that
drives a wheel 81 of twice its size, which wheel thus makes but one rotation to
two rotations of the folding cylinder, and of course to each two sheets cut from the
web. A cam groove 82 in the side of this wheel receives the pin 83 of the con-
necting rod 84, one end of which is forked to embrace the stud of the wheel 81, and
the other end is jointed to an arm 85 secured to the shaft of the switch 79.
The cam groove 82 is of such a form and so timed as to cause the points of the
switch to remain down during the passage of the first sheet through the sheet
breaking rollers 71, 72, as in Fig. 16, intercept said sheet and direct it up between
the tapes 12, 76, into the longer path of travel to the folding cylinder and to lift
the points of the switch during the passage of the open space between the sheets,
and thus guide the second sheet through the direct or short path to the folding
cylinder, as in Fig. 15.
The folding cylinder, as will be evident, does not now act as a collector, it will
therefore make each alternate revolution without any sheet upon it.
These devices operate as follows:-
The web of paper leaving the cutting cylinders partially severed is upon being
caught between the sheet breaking rollers 71, 72, torn from the web and led
between the tapes 12, 76, by the action of the switch 79.
When the second sheet is caught between the sheet breaking rollers 71, 72, the
switch 79 will be in position to guide it direct to the cylinder, where meeting the
first sheet the two sheets will be delivered one upon the other, and will be seized
by the fingers 31 and carried on around the cylinder and be folded together, being
released by the fingers just before they are projected into the nip of the folding
rollers 21, 22.
The first sheet of each pair may, if desired, receive a line of paste either longi-
tudinally or transversely during its passage between the tapes 12, 76.
A paste disc and vat 86 for giving a longitudinal line of paste is placed between
the turning cylinder 73 and the roller 74, so that the sheet in passing it receives a
line of paste, see Fig. 15.
For giving a transverse line of paste a paste blade 87 is inserted lengthways in
the turning cylinder 73, and projects slightly above its surface, so that in passing
the supply roller 88 which runs in a vat or trough 89 it receives from it a quantity
of paste which it imparts to the sheet as the sheet passes over the turning cylinder,
said paste blade being cut away to allow the tapes to pass over the turning cylinder
without receiving any paste.
It is evident that the first sheet might be switched in a longer path of travel
downwards instead of upwards, and also that the paste might be applied to the
second sheet instead of the first.
Both these modifications may be used for folding single sheets by fastening the
switch in one position to cause the sheets to pass through the same channel to the
folding cylinder and adding a duplicate pair of cams, as before described.
When cylinders provided with one or more continuously rotating folding blades

are employed they may be made to deliver sheets into two sets of folding rollers
alternately as desired. This is effected by mounting on. the end of the folding
blade shaft and outside the cylinder head a pinion gearing with the internal teeth of
an excentric-oval wheel, has the centre of the cylinder for one of its foci, whereby
that portion which extends towards the folding rollers is concentric to the cylinder.
This arrangement is shewn on. Sheets VIII., XII., XIII, and XIV., in which
Fig. 1, Sheet XII., is a side elevation, Fig. 2, Sheet VIII., is a plan view, Figures 3,

sheets, or, whereby one of said folding blades may be removed and the other operate
at one of the pairs of rollers in folding whole sheets. Fig. 9 is a front elevation,

apparatus is shewn in Figures 17 and 18, which illustrate in part sectional eleva-
tions the operation of the folding blade actuating mechanisms when the same are
stationary, and arranged to cause the folding blade to operate with a single pair of
stationary rollers at each rotation of the cylinder. Figures 19 to 22, Sheet XIII.,
illustrate a further modification of the apparatus, wherein the cam which projects
the folding blade shaft is in the form of an excentric, Fig. 19 being a front elevation,

form of the excentric; while Fig. 23 is a diagram illustrating the gripper motion.
This sheet delivering apparatus is designed to be attached to a web perfecting
printing machine, from which it will be so driven that its mechanism will cooperate
with those of the printing machine, and sheets printed by the latter will be con-
ducted to the former, and therefrom in a folded condition.
The mode of connecting this apparatus to the printing machine will be well.
understood by reference to the before quoted Patents.
In order that this arrangement may be more readily understood the structure
and operation of the main apparatus, as illustrated in Figures 1 to 8, will first be
described, and then its modifications explained.
The revolving cylinder 30, which supports a rotating folding blade 1, and upon
which the sheets are conducted and rest when doubled by said folding blade in the
nip of one or the other of pairs 51, 52, and 55, 56, of stationary folding rollers,
which are journaled in the frame in the rear of said cylinder is slotted at proper
points on the periphery to permit the passage of the folding blade 1 and the
grippers 19. This cylinder 30 is mounted upon a shaft 31, which carries at one
end a toothed wheel 62 that imparts motion to the other parts of the apparatus,
and which may be the wheel through which motion is received from the printing
machine.
The folding rollers are rotated in unison with the cylinder by means of
pinious 58, 59, gearing the pairs of folding rollers together, and driven by a toothed
:

page_text: wheel 65, fixed on one end of the cylinder 30 (which wheel obscured in Fig. 1 by
the wheel 62 is fully shewn in Fig. 2):
The rotating folding blade. 1. projects from a shaft.4, which is attached by means
of arms 11, 12, to a rock shaft,5 that turns in bearings in the heads of the cylinder 30.
The folding blade shaft projects beyond one head of the cylinder 30,.and carries on
that end a driving pinion 13-that gears with an internal toothed wheel 32. This
wheel, as illustrated in the main apparatus, is oblong in form, and has the centre
of the cylinder 30 for one of its foci, whereby that portion of it which is extended
toward the stationary folding rollers stands in an excentric position with respect to
the cylinder 30, and will, be hereinafter referred to as the excentric portion of said
wheel.
This wheel has connected with it a cam 33; the groove of which is concentric
with the perimeter of said wheel, in the groove of which cam runs a bowle of the
rocking arm 6, which is fast on the end of the folding blade rock shaft 5. As the
cylinder 30 revolves, this cam 33 so rocks the shaft 5 that the pinion 13 is kept
constantly in gear with and rotated by the wheel -32, and while following the
excentric portion thereof the blade is protruded beyond the periphery of the
cylinder, and caused to enter between and withdraw from the stationary folding
rollers.
The wheel 32 is hung on the shaft 31 so as to oscillate thereon, whereby its excentric
portion is caused to travel back and forth from and to the folding rollers 55, 56,
and 51, 52. This movement of the wheel 32, which carries with it the cam 33, is
accomplished by a crank rod 41 that is connected with a wrist pin 9 on said wheel
and to a similar pin on a crank disc 42. This disc is fast on a short shaft 43 that
carries on its outer end a toothed wheel 61, which is geared with a pinion 60, on one
end of the cylinder shaft 31. This pinion 60 is but one half the size of the wheel 61,
and consequently causes said, wheel 32 and the cam 33 which it carries to move in
the proper direction and a suitable distance at each second revolution of the
cylinder 30.
The cylinder is furnished with grippers 19, the shaft 20 of which has its bearing
in the heads of the cylinder beyond which it protrudes, it being furnished at one
end with rocking arm 21 that engages with the main gripper cam 23.(see
Figures 1, 2, and 7) when the grippers are to be opened to receive and seize a sheet,
and at the other end with a rocking arm 22 that engages with an auxiliary gripper
cam 24, which is fast upon the inner face of the cam 33, and opens the grippers to
release the sheet. These grippers are closed by means of a spring seated rod 25
connected with a rocking arm on their shaft as is common.
The sheet conducting tapes 34, 35, connect with the cutting cylinders of the
printing machine, the set 34 running over the cylinder 30 and returning around
the folding roller 51, and the set 35 running over a roller 44 set near the periphery
of the cylinder while the space between the cylinder 30 and roller 44 is spanned by
guards 36 that enter grooves in the roller.
The operation is as follows:-A sheet conducted onto the rotating cylinder 30
by the tapes 34, 35, and guards 30 will be seized by the grippers 19, which are
then opened by the main gripper cam 23, and carried around upon the surface of
the said cylinder. As the sheet is thus being carried by the cylinder the pinion 60
will so rotate the wheel 61 that the crank rod 41 will impart a slowly oscillating
movement to the wheel 32 toward the folding rollers 55, 56, causing the central
point of the excentric portion of the wheel 32 to arrive at said rollers and remain
there during the folding operation and while the crank rod 41 is passing its centre,
as shewn in Fig. 3. During this rotation of the cylinder the rocking arm 6 will,
following the groove of cam 33, cause the shaft 5 to be so rocked that it projects
the blade shaft 4 and pinion 13 outward and inward, thus forcing said pinion
to remain in gear with the wheel 32, and be so actuated thereby.as to rotate the
blade into and out of the rollers 55, 56, whereby the sheet is doubled into the nip
of said rollers, it being folded in passing through the same. As this folding blade 1
performs its folding operation the grippers 19 are opened to release the sheet by

page_text: contact of their rocking arm 21 with the main gripper cam 23. As the continued
rotation of the cylinder brings its grippers 19 into position to seize a second sheet
the crank rod 41 will oscillate the wheel 32 and cam 33 toward the folding
rollers 51, 52, at which the eccentric position of said wheel 32 will arrive and
remain while the crank rod is passing its other centre as in Fig. 4, Sheet XIII.,
during which time the rotating folding blade projected and withdrawn, as before
described, will co-acting with the said folding rollers fold or double the second sheet
between them, the auxiliary gripper.cam acting to release the sheet in proper time,
which, by the oscillating movement of the wheel 32 and cam 33, has been brought
into the proper position to thus act. The folding blade 1 is thus caused to fold the
sheets alternately into the folding rollers 55, 56, and 51, 52. The folded sheets
emerging from the rollers 55, 56, and 51, 52, may be delivered directly to a piling
apparatus, or be carried by tapes to folding machines of either the vibrating or
rotating type, and arranged to fold the same one or more times on lines parallel
with their first fold, at right angles thereto, or both.
This apparatus is shewn as provided with two such folding machines whose
carrying cylinders 40, 50, are arranged one above the other, and geared together so
as to revolve in unison by toothed wheels 69, 70, 71. These cylinders are of one half
the size of the cylinder 30, and being driven turn for turn therewith by means of a
toothed wheel 64 on one of the shafts which gears through an intermediate 63
with the wheel 62 on the shaft of cylinder 30, they are caused to move at ouve half
its surface speeds.
The sheets are directed from the folding rollers 55, 56, and 51, 52, to the
cylinders 40, 50, by means of interposed conducting channels. One of these channels is
formed by sets of tapes 27 that run from the folding roller 56 to a roller 72 set near
the cylinder 40 and overlying rods 29 that reach from the folding roller 55 over
said cylinder, the space between the roller 72 and the cylinder 40 being spanned by
guards 74 entering grooves in said roller 72. The other channel is formed by sets
of tapes 28 that run from the folding roller 52 to a roller 73 sėt near the cylinder 50
and over lying rods 39 that reach from the folding roller.51 over said cylinder, the
space between the roller 73 and the cylinder 50 being spanned by guards 75
entering grooves in the roller 73.
The cylinders 40, 50, are each provided with a folding mechanism of like con-
struction, that, connected with the cylinder 40 will therefore be described, it being
understood that corresponding parts in each marked with like reference characters,
have same construction and mode of operation. Said folding mechanisms consist of
a rotating folding blade 2 projecting from a shaft 8 that is journaled in the heads
of the cylinder, one end of said shaft being extended beyond the cylinder and
provided with a driving pinion 37. This pinion engages with an internal toothed
wheel 38 that is fixed to the side of the frame so as to stand concentric with the
cylinder. As the cylinder rotates, the pinion 37 remaining in gear with the
wheel 38 is caused to continuously rotate, so that while turning many times at
each rotation of the cylinder according to the proportion of the gearing will during
one of its rotations be protruded between and withdrawn from the stationary
folding rollers 53, 54. A set of grippers 86 for controlling the sheet are provided
and operated to seize and release the sheets at the proper times by means of a
rocking arm 85 and stationary cam 84 fixed on the side frame. These cylinders 40, 50,
and the folding mechanisms they carry, are then so operated and timed as to
capacitate them to manipulate the product delivered to them from the cylinder 30,
which being once folded and thereby reduced to one half its former size is suited in
dimensions to those of the cylinder 40 or 50. Such a folding mechanism is shewn
in the Patents above referred to.
The apparatus may be modified as is shewn in Figures 9 to 15, by providing its
cylinder 30 at each end with a stationary oblong internal toothed wheel fixed to
the frame, so that the excentric portion, one, as 32, which project toward the folding
rollers 51, 52, and that of the other, as 45, shall project toward the feeding
rollers 55, 56.

page_text: The cylinders 30 is slotted at opposite points and there provided with bearings
for two rotating folding blades as 1,7, and their appurtenances, and at right angles
thereto in like manner, arranged to receive two sets of removable grippers as 14, 15,
and their appurtenances. The folding blade 7 is removable, and a set of grippers 16
are constructed so as to be adjusted in its bearings. The auxiliary gripper cam 24
is arranged to be removable from the cam 33 of the wheel 32, and a main gripper
cam 46 is fixed to the inner face of the cam 33 of the wheel 45.
The structure and mode of operation of the rotating folding blades and their
actuating mechanism are the same as has been hereinbefore described with respect
to the folding blade 1, when its wheel 32 stands in the same position relative to the
folding rollers 51, 52, as here represented.
The apparatus thus modified may be arranged to fold large sheets through the
rollers 51, 52, as follows:-The cylinder with its folding blade 1 in place is further
supplied with the grippers 16. These grippers are placed in the bearings opposite
to those supporting the rock shaft 5 of the folding blade 1 and operate with respect.
to said blade as to the grippers 19 herein before described, but as bearings
sometimes supporting the rock shaft of the folding blade 7 and their position for
that purpose is one which will not accommodate the hangings of the grippers 19,
the said grippers 16 have their rock shaft 3 fixedly sustained by arms 47, 48, that
are supported by a shaft 49 that enters the said. bearings set screws connecting
them with the cylinder heads. The shaft 3 is thus held in a position to insure a
proper operation of the grippers by the contact of its rocking arm 17 with the main
gripper cam 46.
Each sheet received from the tapes 34, 35, will be seized by the grippers 16 and
carried by the cylinder 30, and folded into the rollers 51, 52, by the rotary folding
blade 1 in precisely the same manner as has been described with respect to the
said mechanism when operating, as in Fig. 4.
When it is desired to fold half sheets the grippers 16 and their hangings are
removed, and the folding blade 7 adjusted in their place, as in Figures 13 and 14.
This folding blade has the same construction as the folding blade 1, and is in like
manner adjusted and operated, except that its driving pinion 76 and rocking arm 77
extend into engagement with the wheel 45 and its cam 33. The grippers 14
and 15 (each set and the mountings being alike, except that the set 14, illustrated
in Fig. 16, has rocking arms 78, 79, projecting from opposite ends of the cylinder,
while the set 15 has but one such arm as 79) are now adjusted in place as in
Figures 13 to 15. The auxiliary gripper cam 24 is also fixed to the cam 33 of the
wheel 32 (see Figures 13 and 14.)
The first half sheet received from the tapes 34, 35, will be seized by the
grippers 14, which are opened and closed for that purpose by the contact of their
rocking arm 79 with the main gripper cam 40, and carried around upon the
cylinder 30 until the middle of the sheet has reached a position to be acted upon by
the folding blade 1, when the grippers 14 will be opened to release it by the
contact of their rocking arm. 78 with the auxiliary gripper cam 24. This sheet
will thereupon be doubled into the nip of the rollers 51, 52, by the folding blade 1,
which controlled by the cam 33 and the wheel 32 will be projected into said rollers.
The second sheet received will be seized by the grippers 15, which are opened
and closed for that purpose by contact of their rocking arm 79 with the cam 46,
and this sheet will be carried round with the cylinder until its middle portion has.
reached the folding rollers 55, 56, whereupon the grippers 15 will be opened by
their rocking arm 79 again coming into contact with the cam 46, and the folding
blade 7 which is controlled by the cam 33, and wheel 45 will be projected and
fold the sheets into the said rollers 55, 56.
In this modification the proportion of the teeth of the driving pinions of the
folding blade are to those of the 32 and 45 wheels as 1 is to 3, so that one of said
blades shall not in making one of its inoperative turns be projected beyond the

page_text: periphery of the cylinder, and strike the sheet it will fold at its next turn, as
would be the case if that proportion were less as 1 to 5.
The modification Figures 17 and 18, Sheet XIV., shews the arrangement of the
parts when the apparatus is designed to operate upon full-sized sheets and to fold
them at one pair of stationary rollers 51, 52. Their structure and operation do
not differ froin those already described, as shewn in Fig. 4, Sheet XII. (as the
characters of reference indicate), except that the foci of the oblong wheel 32 are in
a plane supposed to be parallel with that of the bed plate of the machine and the
cam 33, single pair of folding rollers used and the gripper cam 23 are corres-
pondingly placed.
The modifications illustrated in Sheet XIII. shew the stationary wheel 32 to be
circular instead of oblong, which being greater in diameter than the cylinder 30)
and set excentrically with respect thereto provides what has been called the
excentric portion of the wheel 32, that is protruded beyond the cylinder toward
the folding rollers.
As shown in Figures 19, 20, and 21, two excentrically grooved fixed cams 33 for
projecting and withdrawing the folding blade shaft to and from the centre of the
cylinder are provided. One of these cams 33 is attached to the wheel 32, and the
other fixed to the frame-work at the opposite end of the cylinder, and both cams
are set so that their grooves stand in the same excentric relation to the cylinder
30 as that given to the wheel 32.
The folding blade 1 has its shaft 4 carrying the driving-pinion 13 set in boxes 80
that slide in radial grooves 82 in the heads of the cylinder 30. These boxes have
a pin 83 projecting from them into the cam groove 33, so that while the cylinder 30
rotates the folding blade 1 the teeth of whose driving pinion 13 are to those of the
wheel 32 as 1 is to 3 will be forced to remain in gear with the said wheel, and
make but three rotations, while the cylinder rotates once, two of which rotations
are inside the periphery of the said cylinder, and during the other rotation of
which the blade is projected from and withdrawn toward the centre of the cylinder,
and is thus while rotating caused to enter and withdraw from the folding-rollers
and perform the folding operation.
In the modification Figures 22 and 23 the structure of the parts differs from
that just described in the substitution for the cam 33 of stationary excentrics 81 to
the straps 84 of which the sliding boxes 80 carrying the folding-blade shaft are
fixed. In these modifications Sheet XIV. the grippers 19 are opened by a cam 23
projecting from one of the fixed cams 33 or excentrics 81, as will be readily
understood.
When it is desired to apply a transverse line of paste upon the surface of a sheet
of paper while the same is passing over a vevolving supporting cylinder, a
continuously-acting apparatus is combined with such supporting cylinder, so that
when the mechanism is in operation and the pasting blade is moved into contact
with said supporting cylinder, while it is uncovered or not supporting a sheet, the
line of paste deposited upon its surface by the pasting-blade will be removed, so
that said paste may not be carried onto the inner surface of the next sheet passing
over the said cylinder.
This arrangement is shewn in Sheet XV. of the Drawings, in which Fig. 1
represents a plan view, and Fig. 2 a longitudinal sectional elevation of the pasting
mechanism.
The pasting mechanism consists of a sheet supporting cylinder 20 with which is
combined a rotating pasting-blade 10. This pasting-blade is a simple plate (recessed
as at 31, 32, see Fig. 20, so that it may span the tapes and not cut them off), which
is fastened (so as to be radially adjustable if desired) by screws 34 to an arm 27
(preferably counterbalanced as shewn), that is, mounted upon a shaft 39 and
secured by means of its set screw 33. This blade-shaft carries at its end a toothed
wheel 21 by which it is geared with the pinion 22 on the shaft of the supporting
cylinder 20, and to a similar pinion 23 on the shaft of the paste-fountain-reller 50.

page_text: The blade-shaft 39 supporting cylinder and fountain-roller are geared together, so
that the edge of the blade and said cylinder and roller shall have the same surface
speed. This may be accomplished by suitable gearing, without regard to the size
of the said cylinder and roller. Such relative movements of these devices cause the
pasting-blade to engage and move in unison with the surface of the paste-fountain
roller in receiving paste therefrom, and to engage and move in unison with the
paper in depositing said paste thereon, so that in neither cases does it drag or sweep
over the surface with which it has contact, whereby the paste would be smeared
over both the blade sides and surface of the paper. The paste-fountain roller
which runs in the paste-vat 49 has the quantity of paste its surface shall present to
the pasting blade regulated by a doctor 28, as is common in pasting and inking
mechanisins.
The sheet-supporting cylinder is provided with a conducting apparatus whereby
the sheets are carried to it caused to pass over its surface at the line of contact
therewith of the pasting blade, and delivered to the folding mechanism. As here
shewn this consists of sheet-conducting tapes 17, 18, the former moving from the
roller 11 over or in contact with the surface of the supporting-cylinder 20, around
rollers 13, 15, and returning over the roller 16. The tapes 18 run from the roller
12 in contact with the tapes 17 over the surface of the supporting-cylinder 20, and
return over a roller 14. These tapes are driven at an equal surface speed with the
travel of the supporting cylinder 20 and pasting-blade 10 by means of spur wheels
25, 24, gearing their rollers 13 and 14 together, and an intermediate 26 connecting
the wheel 24 with the toothed wheel 21.
The mechanism thus far described when connected with a mechanism supplying
the sheets successively to it at the tape rollers 11, 12, will operate as follows:-
Each sheet as received will be conducted by the tapes 17, 18, down before and in
contact with the surface of the supporting cylinder 20, and the mechanisms are so
timed that when the middle portion of said sheet or such other portion of it that is
to receive the line of paste, and constitute the line of its ultimate folding overlies
said cylinder 20, the pasting blade which has become charged with paste in passing
in contact with the fountain roller 50 will bear upon the sheet, pressing it against
the surface of the cylinder 20, as in Fig. 2, and imprint or deposit a line of paste
thereon. This sheet constantly moving is conducted onward by the takes, and
delivered from them at the rollers 13, 14. In practice however these tapes will
'connect with the mechanism supplying the sheets and with the mechanism which
is to fold the same, so that the sheets received by them will be conducted through
this pasting apparatus, and be delivered to the folding mechanism..
Now it will be observed that if for any reason the supply of the sheets is
interrupted, as when starting or finishing work, or otherwise, and the mechanism
continues to run so that its pasting-blade make one or more turns, it must in the
absence of a sheet at the point of its contact with the supporting cylinder 20
deposit a line of paste thereon; and further, that if said line of paste remains on
said cylinder 20, it will when a sheet is fed into the mechanism and passes in
contact with the cylinder deposit the same upon the inner surface of the sheet,
which paste being exposed in all further manipulation of the said sheet will smear
the conducting rollers and various parts of the folding mechanism, rendering it
necessary to stop the apparatus and clean the same.
To avoid this means are provided for removing the paste thus accidentally
deposited upon the carrying-cylinder, whereby the apparatus may be run without
sheets, and yet remain clean and in a condition to operate upon the same at all
times. A stripper. 30, consisting of a thin plate of metal, is fixed to the framework
and nicely adjusted so as to bear evenly against the surface of the carrying-cylinder
20; it is thus adapted to strip or scrape off the paste deposited on the surface of the
cylinder, and prevent said paste from being carried around to the point of contact
of the cylinder with the paper. A wiper 40 is also employed to rub upon the surface
of said cylinder and clean from the same any paste which may adhere thereto, so
that the said cylinder shall be perfectly clean when presented to the paper; this

page_text: wiper consists of a metal frame composed of the top plate 5 and sides 4, 6, over the
open bottom of which is stretched a number of layers of soft clothing, as flannel or
other suitable pliable and absorbent material, which are secured to the top plate 5
by means of clamp-plates 2, 3, and suitable screws. The ends of the sides 4 and 6
are suited to rest in bearings formed by angle plates 7, 8, and 1, 9, secured to the
side frames, and in these bearings the said wiper rides and presses by its own weight
upon the top of the cylinder 20, its clothing 41 readily conforming to the surface,
and thus extending over a considerable part thereof.
.
When the paper is fed through this pasting apparatus in the form of a web, which
is partially severed on lines where it is subsequently to be separated to form sheets,
or being whole is to be subsequently divided into sheets, the conducting tapes will
not be needed, and when emitted the pasting blade need not have the recesses 31,
32, but be provided with a continuous edge.
In delivering the printed sheets from the printing machine to the folding
mechanism, more especially when the latter is of the vibrating folding type, the
great speed at which the sheets issue from the printing machine causes them, when
stopped, to "buckle up." To avoid this "buckling" the sheets are brought to the
vibrating folding mechanism between tapes carried by rollers, and immediately
before entering beneath the folding blade are nipped at several points in their width
between brake arms and rest blocks mounted respectively below and above the
sheets. The rest blocks are carried upon a bar attached to the framing, and are,
together with the brake arins, adjustable laterally to suit the various margins of the
printed matter.
This part of the present Invention is shewn at Sheet XVI., in which Fig. 1 is a
side elevation of a vibrating knife folding machine; Fig. 2 is a plan view of the
same; Fig. 3 is an end view of the same; Figures 4 and 5 are views partly in section
shewing the position of the devices when in operation.
Referring to the Drawings, numbers 1 and 2 represent rollers suitably journaled
in the framework 3 of the machine, geared together and driven by gearing, as
represented in the Drawings, or in any other convenient manner. Over these rollers
1 and 2 tapes 4 and 5 pass to and around stretching pulleys 6 and 7 of any desirable
construction. These tapes gradually separate from the point where the rollers 1 and 2
seize the sheet to be folded to the stretching-pulleys 6 and 7, for a purpose herein-
after described.
The sheet controlling mechanism consists essentially of brake-arms 8 and rest-
blocks 12. These break-arms are shewn as secured to a rock-shaft 9, to which is
secured a lever 10 in contact through a pin thereon with a cam 11 positively rotated
in any convenient way. The ends of these brake-arms may be slightly curved
where the operate upon the paper, as shewn in Fig. 5, or may be provided with
friction-rollers as shewn in Figures 1 and 4.
The rest-blocks 12 may be secured firmly to a rigid shaft 13 at any desired point,
so as to operate in connection with the brake-arms S to retard the paper as it inoves
in the machine. 15 is a folding blade, the arm of which is pivotted to the frame of
the machine and operated by a positively-driven cam 16, or in any other convenient
⚫inanner. This folding blade operates in conjunction with a pair of folding rollers 17
and 18 rotated in timely relation to the rollers 1 and 2 in any convenient manner.
21 is a gauge of any common construction against which the edge or leading end of
the sheet will touch before the folding blade operates to double it into the bite of
the rollers 17 and 18.
In operation the sheet supplied either from a table, a printing-press or a folding
mechanism that has previously imparted a fold or folds to it (to the rollers 1 and 2),
is led through the same partially carried by the tapes into position over the folding-
rollers 17, 18. Just before it arrives into the proper position or register to be
folded by the blade 15 and folding rollers 17 and 18, the brake arms 8 through
their rock shaft 9 and its operating cam 11 are elevated, and their ends raise the sheet
and press it near its rear end momentarily or for such time as practice may deter
mine in contact with the rest blocks 12, so as to suspend or retard its movement,

page_text: and enable its forward edge or leading end to slowly approach the gauge 21, gently
abut against the same, and adjust itself in contact therewith without danger of
buckling, and the tapes 4 and 5 being partially separated near the stretching pulleys
6 and 7, above referred to, obviate to a great extent smudging that might arise
from the stopping of the sheet while the tapes continued to move. Upon the move-
ment of the cam 11 the brake arms S are lowered, and their ends being moved away
from the sheet it is free to be doubled by the folding blade 15 into the bite of the
folding rollers 17 and 18.
By changing the form and movement of the cam 11 the brake arms 8 may be so
operated in relation to the rest blocks 12 to retard or stop the sheet as to cause it
to be carried into the proper position or register to be folded upon any predeter-
mined line without the use of a gauge. The rollers 1 and 2 may be those for
making the first or any other fold of the sheet, or they may be feeding rollers, as
shewn in the Drawings. The form or number of the brake arms and rest blocks
may be varied from those shewn in the Drawings so long as they operate to control
the sheet, as above referred to.
Having now set forth the nature of the said Invention of "Improvements in
Apparatus for Making up Sheets of Printed Paper into the Form of Pamphlets,
Magazines, or Newspapers," which has been communicated to me from abroad by
my foreign correspondent, and explained the manner of carrying the same into
effect, I wish it to be understood that under the above in part recited Letters Patent
I claim,
First. The combination of the sheet collecting, conducting, and folding apparatus
with the intermittently acting forwarding rollers 26, 27, substantially as herein
shewn and described with reference to Sheets I., II., and III. of the Drawings.
Second. The combination with a collecting cylinder, constructed as herein shewn
and described, of a pasting disc for laying on a longitudinal line of paste, and mounted
in stationary bearings, and running constantly in operative relation to said cylinder,
substantially as set forth.
Third. The construction and arrangement of the parts severally constituting the
collecting and folding mechanism, as shewn and described with reference to
Figures 7 and 8, Sheet II., and 9, 10, and 11, Sheet III., of the accompanying
Drawings.
ċ
Fourth. The mode of and apparatus for operating the folding and gripping
mechanisms of cylinder folding machines, as shewn and described, with reference
to Sheets IV., V., VI., and VII. of the Drawings, whereby the folding and gripping
mechanisms may be caused to act at any desired interval, as and for the purpose
set forth.
Fifth. The construction and arrangement of the parts, as shewn and described,
with reference to Figures 9 and 10, Sheet VI. of the Drawings, whereby the folding
mechanism may be rendered inoperative, and the cylinder used as a collecting
cylinder only when desired.
Sixth. The combination with the collecting cylinder and its gripping and
primary folding mechanisms, constructed as herein described, of the vibrating
secondary mechanism, as shewn with reference to Figure 27, Sheet VIII., of the
Drawings.
Seventh. The combination of the collecting cylinder, with its gripping, pasting,
and primary folding mechanism, as herein described, with the rotary secondary
folding mechanism, as shewn with reference to Sheets IX., X., and. XI. of the
Drawings.
Eighth. The construction, arrangement, and operation of the parts, as shewn and
described with reference to Figures 1 to 8, Sheets VIII., XII., and XIII. of the
Drawings, whereby whole sheets of paper may be directed from the folding cylinder
into two different channels alternately, as and for the purpose set forth.
Ninth. The construction, arrangement, and operation of the parts, as shewn and
described, with reference to Figures 9 to 16, Sheet XIV. of the Drawings, whereby
whole sheets of paper may be directed into a single channel, or half sheets into

page_text: two channels alternately from the folding cylinder, as and for the purpose set
forth.
:
Tenth. The construction, arrangement, and operation of the parts, as shown and
described, with reference to Figures 19 to 23, Sheet XIII.'
Eleventh. The arrangement of, apparatus for applying a transverse line of paste
on the paper in combination with a stripper and wiper, as shewn and described
with reference to Sheet XV. of the Drawings.
.
Twelfth. The arrangement of apparatus, as shewn and described, with reference
to Sheet. XVI. of the Drawings, or any mere modification thereof, for retarding the
speed of travel of the printed sheets of paper for the purpose set forth.
In witness whereof, I, the said William Conquest, have hereunto set my hand
and seal, the Sixteenth day of February, in the year of our Lord One thousand
eight hundred and eighty.
