WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN PAPER CUTTING AND FOLDING
MACHINERY." A communication.
The first part of this Invention relates to a paper folding machine operating in
combination with a printing press, and consists in improved mechanism for taking
the sheets from the printing press and delivering them to the folding machine; also
in making two or more of the folds at right angles to each other by means of
revolving creasers and griping cylinders arranged at right angles to each other.
The second part of the said Invention consists in a cylinder provided with
grippers and movable creasers for separating the sheets and transmitting them from
the cutting cylinders to the folding mechanism.
The third part of the said Invention consists in the combination of the creasing
and gripping cylinders with the former arranged above the latter, so as to receive
the sheets from the press with the inside of the sheet uppermost; also in a modifi-
cation of the grippers, and also in the combination of the creasing cylinder with the
blower for holding the sheets instead of grippers.
The fourth part of the said Invention consists in the use of a revolving creaser in
connection with a pair of folding rollers, which also revolve about a common axis.
The fifth part of the said Invention consists in the employment of a rotating
creaser and cylinder for making the last fold in the sheet, and also in an improved
packing device to accommodate the increased speed obtained by the use of a single
delivery.
The sixth part of the said Invention consists in a modification thereof for
adapting it to a folding machine in which the sheets are fed from a table by hand.
The seventh part of the said Invention consists in a drop roller for running out
the sheets as they are fed down from the table, instead of the vibrating gripper

page_text: frame described above; also in a rotating catch to arrest the sheet as it is
approaching the stop at the rear of the machine just before the second fold is made,
and also in a rotating stop to be used in connection with the packer to prevent the
return of the folded papers.
The eighth part of the said Invention consists in mechanism for delivering the
sheets from the printing press straight without folding.
The first part of the said Invention is carried into practice by the aid of the
following devices:-Carrying tapes are combined with the revolving folding
mechanism and pasting wheel. One folding cylinder is provided with a recess,
and another cylinder with a projection for separating the sheets from the previously
perforated web. The said recessed cylinder is provided with grippers, and the
other cylinder having a projection as described is provided with a creasing blade
and grippers or other suitable holding device for separating and folding the sheets
as they are delivered from the press. The said grippers are constructed with their
front edges beveled, and they are held in position by springs which gives them a
yielding support. The recessed cylinder has its hinged spring grippers constructed
with their rear ends projecting beyond the periphery of the cylinder, so as to be
opened by contact with the cylinder or roller. The rotating cylinder or grooved
folding bar is provided with suitable grippers and a rotating creaser, both arranged
at right angles to the mechanism for making the tirst fold in the paper.
In some instance I combine with the folding cylinder an independently revolving
creasing blade, so as to permit the sheets to be fed in between the creaser and
cylinder at their ends instead of in front. The carrying tapes run parallel to the
shafts of the cylinder and creaser.
When I employ the aforesaid rotating creaser and rotating gripping folding
cylinder, the two are so speeded that the edge of the creaser moves more slowly
than the surface of the groove in the cylinder in which it works while they are in
contact. The aforesaid rotating cylinders, creaser, and folding cylinder are arranged
at right angles to the folding rollers, and provided with suitable mechanism for
conveying the sheets from the roller to the cylinders. The rotating creaser, rotating
grooved folding bar, and grippers are arranged in the front side of the groove, so
that the creaser will more readily leave the paper, and the tearing of the latter will
be prevented as it is pulled around the cylinder. The folding rollers have stops
properly arranged in combination with the conveying tapes. There is a raised
piece on the bottom of the trough and a reciprocating packer, and the vibrating
creaser has a cushioning spring for the creaser arm.
For carrying into practice the second part of said Invention I employ a com-
bination of parts comprising a cylinder constructed with movable sections, and
another cylinder provided with grippers and creasers for feeding the sheets from
the cutting cylinders to the folding cylinders. The said cylinder, having movable
sections, is combined with a cutting cylinder provided with a rubber strip, and the
cylinder provided with the grippers and creasers has projections on its surface and
rubber strips. A cam projection is attached to the gripper rod of another cylinder
for the purpose of opening and closing the grippers.
L
In connection with the third part of the said Invention I use a creasing cylinder
and carrying tapes, one of which passes around and above the said cylinder, a
folding cylinder, and roller, and I combine with the said cylinders a blower. The
creasing cylinder is provided with points for holding the sleets on the same.
For carrying into effect the fourth part of the said Invention I employ the rotating,
creaser and a pair of rotating folding rollers which revolve together about a common
axis, and conveying tapes in combination with a folding cylinder..
The objects of the fifth part of the said Invention are effected by the combination
of the rotating creaser, cylinder grooved as described but without grippers, and
rollers for making the last fold in the sheet. Also by the employment of a packer
composed of two reciprocating parts in combination with a stopping flap.
In practising the sixth part of the said Invention, I combine and arrange the
creaser and the cylinder having two or more grooves in such a manner that the

page_text: latter performs a greater number of revolutions than the former, so that the said
creaser enters the grippers only when making a fold. This part of the said Invention
also comprises the combination of the rotating creaser, gripper cylinder, and vibrating
gripping fraine. The folding rollers are arranged at a right angle to the folding
cylinders, and with their axis inclined. This part of the said Invention also
comprises the combination of the aforesaid stops, the trough, and the reciprocating
packer.
I
For the purpose of the seventh part of this Invention I combine the rotating
creaser, the gripping cylinder, the dropping feed roller, and revolving discs or
switches, and arrange fixed and rotating stops in combination with the same.
also arrange in combination with one of the said revolving stops a reciprocating
packer, similar to that above described.
And in connection with the eighth part of the said Invention I employ a
delivering cylinder provided with grippers and flies in combination with a yielding
receiving board and retaining fly; and I provide the cylinder with suction bellows.

the said William Robert Lake in the Great Seal Patent Office on the 21st
October 1876.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN PAPER CUTTING AND FOLDING
MACHINERY." A communication from abroad by Walter Scott, of Chicago, Illinois,
United States of America.
The first part of this Invention relates to a paper folding machine operating
in combination with a printing press, and consists in improved mechanisın for
taking the sheets from the printing press and delivering them to the folding
machine; also in making two or more of the folds at right angles to each other
by means of revolving creasers and griping cylinders arranged at right angles to
each other, and in various details of construction. This part of the said Invention
is illustrated in Figures 1, 2, and 3 of the Drawings.
Figure 1 represents a plan of the folding machine and cutting cylinders of a
printing press; Figure 2 a side elevation of the same, and Figure 3 a rear end
elevation of the folding machine.
A, A¹, represent the cutting cylinders of a printing press which may be of any
suitable construction. Tapes B, B, running over pullies a, a, receive the printed
sheets from the cutting cylinders, and deliver them to the first set of folders at
the front end of the folding machine. A paste pot b is attached centrally to the
front end of the folding machine, and the sheets as they are delivered to the latter
are carried over a paste wheel C to which they are held by the wheel c, and thus
a narrow line of paste applied to the sheets along the centre thereof. D and E are
revolving folding cylinders mounted in suitable bearings at the front end of the
machine. These cylinders may be constructed in rings or sections, or may be
made entire, as may be thought desirable. The upper cylinder D is provided
with a series of yielding grippers d, which are attached to a rock shaft d', one end
of which terminates in a crank arm & carrying a friction roller, which is brought
into contact with a suitable cam by the revolution of the cylinder to open the
gripers at the proper time to release the sheet. The forward edge of these grippers
is slightly bevilled to facilitate the entrance of the creasing blade between them
and the body of the cylinder. These grippers are closed by means of springs d³
behind them, as seen in Figure 2 of the Drawings. The grippers instead of being
fastened to a single rod may be placed loosely thereon, or attached independently
to the cylinder or held in position by independent springs, and opened by their
outer ends, which project a little beyond the periphery of the cylinder coming in

page_text: contact with the folding roller F. This cylinder is also recessed upon its surface,
as shewn at d', the lower cylinder E is also provided with a series of grippers e
of ordinary construction for seizing the front edge of the sheet as it is delivered
from the cutting cylinders by the carrying tapes through the guide rods b¹. The
grippers e are fastened to a rod e', which is similar in construction and operation
to the rod in the cylinder D. This cylinder E is also provided with a creasing
blade e² and a projection e³, which corresponds to the recess d' in the cylinder D.
This mechanism is so arranged that as the sheets are delivered to the folding
cylinders D, E, the projection will come opposite the perforations in the sheet
made by the cutting cylinders, and will ensure the separation of the sheet by
forcing it into the recess in the cylinder D, at the same time pushing it back
out of the way of the grippers e, which seize the advancing end of the perforated
web. A roiler F is placed against the cylinder D, and is mounted in adjustable
bearings. Carrying tapes G passing around the roller F and the pulleys g, g,
receive the folded sheets from the cylinders D, E, and carry it forward between a
cylinder H and rotating creaser I. Above the carrying tapes guide rods J are
placed, the bent forward ends j of which project into grooves or spaces in the
cylinder D. Just below the plane of the carrying tapes is placed a stiff rod or
roller K in front of the plane of the shaft of the cylinders H. Fingers L are
attached to a bar of the supporting frame, and a little below them is arranged
another series of similar fingers L, which are attached to a rock shaft . This
shaft also carries an arm , provided with an anti-friction roller, which is held in
contact by a spring with a cam guide m on the same shaft as the revolving
cylinder M, so that whenever the roller enters a depression in the cam the two
sets of fingers are brought into contact with each other. The cylinder H and
revolving creaser I are arranged at right angles or nearly so to the folding rollers
and creaser heretofore described. The cylinder H may be constructed similar to
the cylinder D, or there may be mounted upon the shaft a grooved bar h, the
front face of which is recessed to receive the outer ends of grippers ¹, which are
fixed on the front side of the grooved bar upon a rod 2, and are held in position
and operated in a similar manner to the grippers on the cylinder D already
described, except that there are two cams which operate the rod both to open and
close the grippers to receive and release the paper at the proper intervals.
creaser I is arranged just above the gripping cylinder H, and their shafts are
provided with eccentric gear wheels and i, so that with every revolution of
the cylinder the creaser will place the sheet within the bite of the grippers and
the speed of the two will be variable for a purpose which will be mentioned here-
after. The cylinder H also carries a creasing blade, which operates in connection
with the cylinder M, mounted upon a shaft parallel to that of the cylinder H.
The cylinder M is similar in construction to the cylinder D, and is provided with
suitable grippers m¹ to receive and hold the sheet placed within them by the
creaser on the cylinder H.
The
A circular cutter N is mounted upon a shaft n which is rotated by any suitable
device. This cutter is provided with a serrated edge which fits in a groove near
the outer end of the cylinder H and trims the edges of the sheet after it has
received its second fold and just before it is received upon the cylinder M. A
roller O is placed just below and a little at one side of the cylinder M with which
it is held in contact and operates in the saine manner as the roller F, being also
mounted in similar adjustable bearings o. Guides o' below the cylinder M, into the
grooves of which the upper ends of the guides enter, direct the sheets as they are
delivered from the cylinders M and O to tape conveyers P, which pass around
pulleys p, p, and carry the sheets out horizontally over a pair of folding rollers
Q, Q, to a fixed stop g. A second stop g' is reciprocated vertically by means of
any suitable mechanism, and is provided with rods q2 which extend underneath
the tape conveyers toward the stop q A vibrating creaser R acts in connection a
with the rollers 7 in the usual well known way. The creaser is mounted upon a
rock shaft r, and its arm is extended back from the shaft and is provided at its

page_text: extremity with a roller which is held in contact with a cam S on the shaft s by
means of a spring ¹. A spring &¹ is located just above the end of the creaser
arm which operates as a cushion to the vibrating creaser. A reciprocating
packer T is placed in the receiving trough U, into which the folded sheets are
delivered from the rollers Q. This packer may be mounted upon small rollers t or
upon sliding arms t The bottom of the receiving trough U just below the
rollers Q is raised slightly, as shewn at u.
The folded sheets are discharged upon
this raised bottom, and being pushed off from it by the reciprocation of the
packer, they fall to the level of the real bottom of the trough, and are prevented
from returning by the raised bottom u. For the same purpose I attach a yielding
stop or stops to the machine above the packer to prevent the falling over of the
sheets backwards. The packer reciprocating stop q¹ and vibrating creaser are
all operated from the shaft s, which is geared so as to make one revolution for the
delivery of every two sheets upon the tape conveyors P, so that each one of the
devices named operates upon two sheets at a time. If only three folds are desired
in the sheet the shaft s is thrown out of gear so that the last set of rollers and
creaser will not be operated, and the shects will then be conveyed by the tapes P
into a trough V underneath a plunging packer v. Motion is communicated to
the folding machinery from the press by means of the transmitting shaft W
provided with suitable gear wheels, as shewn. The shaft W is geared directly
with the shaft of the cylinder E,, which in turn communicates motion to the
different parts of the machine by suitable gearing, the rear portion receiving
motion from the transmitting shaft X which is geared to the shaft of the cylinders
E and M.
The operation is as follows:-The web of paper having been perforated in the
usual manner by the cutting cylinders A, A¹, is conveyed by the tapes B to the
cylinders D, E, between which it passes, and is carried along by contact therewith
until the projection on the cylinder E comes opposite the corresponding recess in
the cylinder D, when the sheet is separated from the web, and the grippers e brought
into action as described above. The end of the web being held by the grippers c, is
carried around upon the cylinder E until the creaser e and grippers & come opposite
each other, when the sheet is forced into the bite of the grippers by the creaser, and
in a doubled condition is carried back by the cylinder D, the grippers e having in
the meantime released their hold, and is passed between the cylinder D and roller
F, the grippers & being opened to admit of its being stripped from the cylinder D
by the rods J. In this operation of making the first fold the pasted surfaces are
pressed together and the sheet passes on to the conveying tapes G, by which it is
carried to the rear under the guide rods J, between the gripping cylinder H, and
the creaser I being stopped at the proper time by the fingers L, L, catching the
rear end a moment, just before the sheet reaches the stop bar at the rear end of the
machine when the folded sheet is bent into the bite of the grippers by the creaser
I, and the sheet is drawn over the rod K, thereby making another fold, and carried
down in front of the cylinder M, the edges being at the same time trimmed by the
cutter N. The creaser on the cylinder H bends the sheet into the groove in
the cylinder M, where it is held by grippers and carried around between this
cylinder and the roller O thereby making another fold. The sheet is carried thence
As soon as it
by the conveyors P over the rollers Q until it reaches the stop q.
is thus delivered the stop g¹ is raised, and the rod q raises the sheet from the tapes
while a second sheet is delivered by said tapes against the stops 7'. The creaser R
then comes down upon the two sheets, bends them into the grip of the rollers Q.
by which the last fold is given to the sheets, and they are discharged in front of the
packer T upon the raised floor of the trough U, and are carried out of the way by
the reciprocation of the packer. The eccentric gear wheels h³ and i are so arranged
as to retard the notion of the creaser I while it is in contact with the grooved
folding bar or cylinder so that the creaser will rest against the back edge of the
groove as it is withdrawn, thus enabling the gripper to seize the paper more
readily.

page_text: The second part of the said Invention relates to a cylinder provided with grippers
and movable creasers for separating the sheets and transmitting them from the
cutting cylinders to the folding mechanism. This part of my Invention is illustrated
in Figure 4 of the Drawings, in which A, A¹, are the cutting cylinders attached to
the press. Narrow sections a of the surface of the female cutting cylinder A corre-
sponding to the cutting grooves in said cylinders are made movable. They are
forced out by means of springs, and are firmly held in this position during the
operation of cutting by means of cams a², to which the sections a are fastened. The
sections a are drawn within the cylinder by similar cams 3 under whicli tlie same
rollers are carried. The cylinder A¹ is provided with a cutter at of ordinary con-
struction. The cylinder B corresponds to the gripper cylinder E described in
connection with the first part of my Invention, except that the creasers bare movable,
and may be retracted within the cutting cylinder A. The grippers 6 are similar to
the grippers e on the cylinder E, herein-before described. The cylinder C corresponds
to the cylinder D comprised in the first part of this Invention, and is similar to
it in construction. On the cylinders A¹ and B are placed narrow rubber strips a
and b. Tapes D pass around the cylinder B and pulleys E, and are held taut by
tightening pulleys F. The arm upon the end of the gripper shaft on the cylinder C,
by means of which the shaft is rocked, is extended slightly beyond the periphery of
the cylinder and is moved back to open the grippers by coming in contact with
the adjacent cylinders at the points required. The operation is as follows:-The
web having been perforated by the cutter a' is carried forward nearly to the
point of contact between the cylinders A and B. At the same time the section a
which is advancing towards the cylinder B is retracted, and the projections on the
cylinder B enter the recess thus formed in the cylinder A, pressing the paper before
then, and thus separating the sheet from the web, which is firmly held during this
operation by the rubber strips on the cylinders A and B, which are in contact with
the cylinder A. The grippers on the cylinder B having seized the web it is carried
forward with the rotation of the cylinder B until the central portion of a sheet is
opposite the cylinder C, when one of the creasers b is forced out and the sheet is
placed within the bite of the grippers in the cylinder C. This latter operation is
accomplished just after the separation of the sheet heretofore described, and its
release from the rubber strip b². The tapes D facilitate the passage of the sheets
around the cylinder A. by holding them to said cylinder, but they are not absolutely
necessary. The sheets are delivered from the cylinder C in the manner described
in connection with the first part of this Invention to other folding mechanism, and
a switch G may be employed if desired to deliver the sheets alternately.
The third part of the said Invention relates to the combination of the creasing
and gripping cylinders with the former arranged above the latter, so as to receive
the sheets from the press with the inside of the sheet uppermost, also to a modifi-
cation of the grippers, and to the combination of the creasing cylinder with the
blower for holding the sheets instead of grippers. This part of my Invention is
illustrated in Figures 5 and 6 of the Drawings.
In Figure 5, A, A1, are the cutting cylinders; B, B, the carrying tapes which pass
round the pulleys; C, D, the folding cylinder; and E, the gripping and creasing
cylinder. These parts are similar in construction to corresponding parts described in
connection with the first part of my Invention, but as seen in the Drawings the
creasing cylinder E in this case is arranged above the folding or gripping cylinder D
instead of below it, as in the first part of my Invention. The operation of the said
cylinders D, E, is the same as heretofore described, but under the arrangement here
set forth I am enabled to receive the printed sheets from the press with the inside of
said sheets uppermost. The folding roller F must also in this case be arranged above
the cylinder D instead of below it, and the carrying tapes passing around this roller
are placed above the guide rods, and the sheet is shot out between them from the
rotating cylinders. A blower G constructed in the usual manner may be employed
if desired to hold the sheets upon the 'creasing cylinder E, in which case the grippers
on this cylinder may be dispensed with. In place of either of these devices pins e,

page_text: as shewn in Figure 6, may be employed for this purpose. When the pins are used
corresponding holes must be made in the cylinder D, and the sheets are forced upon
the pins by contact with the cylinders. When the blower is used the end of the
sheet is forced up and around the cylinder E, and prevented from following around
the cylinder D, and when the pins are used the sheet is carried up and around
the cylinder E the proper distance, and stripped therefrom by the tapes B which
are underneath the sheet.
The fourth part of my Invention relates to the use of a revolving creaser in
connection with a pair of folding rollers which also revolve about a common axis.
This part of my Invention is illustrated in Figure 7 of the Drawings. The
arrangement of creaser and cylinders in this Figure is similar to that of the
cylinders H and M and creaser I in the first part of this Invention, and I shall
therefore use these letters to indicate corresponding parts in this Figure. The
construction of the revolving creaser I and cylinder M is not modified, but instead
of the series of grippers or a grooved bar and grippers on the cylinder H two
rollers h, h, are employed, which are constructed to revolve together about the
common axis h', and at the same time are caused to revolve about their own axes by
means of suitable gearing attached to the shaft . Tapes h passing around
pulleys are also driven by the rollers h. A revolving creaser h is also attached
to the shaft the same as in the first part of this Invention.
In the operation of this device the creaser I forces the sheet between the rollers h, h,
instead of into the bite of the grippers as in the first part of my Invention, and
the fold is made as the sheet passes between the said rollers. The motion of these
rollers is so timed that when the creaser ' comes opposite the holding groove in the
cylinder M the sheet bas been carried forward by the tapes h², so that just half of it
projects beyond the creaser, and therefore it is in proper position to be folded again
upon the cylinder M in the manner heretofore described. This device for folding is
applicable to any cylinder in the machine.
The fifth part of my Invention relates to the employment of a rotating creaser
and cylinder for making the last fold in the sheet, and also to an improved packing
device to accomodate the increased speed obtained by the use of a single delivery.
This part of my Invention is illustrated in Figure 8 of the Drawings. In this
Figure the revolving cutter N is shown arranged to operate in connection with the
roller O instead of cylinder H, as in Figure 3, thus enabling me to give another
fold to the sheet before the trimming, and facilitating the removal of the trimmings.
Instead of the rollers Q and vibrating creaser R, shown in Figure 3, a rotating
creaser R¹, a grooved cylinder Q1, and a folding roller S¹ are employed to make the
last fold in the sheet. These devices are similar in construction to corresponding
parts heretofore described, except that the cylinder Q is not necessarily provided
with grippers, the folded sheet being so thick at this point that it will be held in
a plain groove firmly enough to be carried forward between the cylinder and the
'roller S¹.
The packer T consists of two parts t, t, constructed with horizontally projecting
fingers t¹, t¹, extending inwardly from sliding posts or bars 12. The fingers are
arranged to pass by each other behind the point of delivery of the folded sheets, so
that upon the completion of the backward stroke of one set the other set can
commence its forward stroke, and thus each set reciprocates only for every two
sheets. A swinging flap Y is supported upon the sides of the receiving trough U
´ in front of the packers, and operates as a stop to prevent the return of the folded
⚫sheets.
The sixth part of my Invention relates to a modification thereof for adapting
it to a folding machine in which the sheets are fed from a table by hand. This part
of the said Invention is illustrated in Figures 9 to 11; Figure 9 is a side elevation
of the folding machine; Figure 10 is'a front end elevation; and Figure 11 is a rear
elevation of the same.
The general construction of the machine is the same as already described in con-
nection with the first part of my Invention, but it is provided with an inclined feed

page_text: board A, mounted upon the frame in such position that the sheets may be fed properly
to the revolving creaser B and folding cylinder C, which correspond with the
cylinders D, E, above described, except that the creaser B is not attached to a
cylinder and has no grippers. A vibrating frame D is attached to a rock shaft D' at
the lower part of the frame, to which shaft motion is communicated in any suitable
manner. Grippers are attached to the upper end of this vibrating frame, but as
they are of ordinary construction a particular description of them is unnecessary.
Bent rods E are attached to a cross bar of the frame in front of the cylinder Č,
which support the sheet when it is drawn out by the vibrating gripper frame. In
this machine the rollers Q, Q, and vibrating creaser R for making the last fold in
the sheet are placed in an inclined position, as clearly shown in Figures 10 and 11
of the Drawings. The packer T and receiving trough U are arranged to accom-
odate this inclined position of the rollers. On the bottom of the trough U are
placed catches or stops u, which hold the lower edges of the folded papers from
returning as the packer T is withdrawn. A. yielding catch or stop Vis loosely
attached to a pin on the frame of the machine, and operates upon the upper edges
of the folded papers to prevent their return on the backward stroke of the packer.
The packer T is recessed on its upper and lower edges to permit of its passing the
catches u and V without interruption.
In operating this machine a bank of sheets is placed upon the feed board, and
as motion is communicated to the machine the vibrating gripper frame D passes
up between the cylinder C and creaser B, seizes the lower edge of a sheet as it is
fed down, and draws it forward between the cylinder and creaser, which are so
geared that the former makes three revolutions while the latter makes but two,
thus permitting the vibrating gripper frame to pass between them and draw out
a sheet without interruption. When the sheet is drawn out about half its length.
the creaser comes down and bends it into the groove in the cylinder in the manner
above described. The subsequent folds of the sheet are effected by devices and
in the manner described in connection with the first part of my Invention.
The seventh part of this Invention is illustrated in Figure 12 of the Drawings,
and relates to a drop roller for running out the sheets as they are fed down from
the table instead of the vibrating gripper frame described above, also to a rotating
catch to arrest the sheet as it is approaching the stop at the rear of the machine
just before the second fold is made, and to a rotating stop to be used in connection
with the packer to prevent the return of the folded papers.
In this Figure A represents the feed board, B. the revolving creaser, and C
the gripping cylinder above described. A roller D is supported upon arms D
on each side of the machine, attached to a rock shaft E, to one end of which
is also attached an arm F, the outer end of which is acted upon by a suitable
cam G to give a rocking motion to the shaft E. The arms H are also supported 4
loosely upon pins on each side of the machine. The rear end of these arms
are connected by rods ¹ to the arms . In their outer ends a shaft I is journalled,
to which discs J are attached. Upon each of the arms d is a stop K, which projects
just above the cylinder C when the. roller D is in a raised position. A double set of
guide rods L projects in front of the machine to receive the sheet as it is drawn out 4
from the table. In place of the fingers L, L³, described in connection with the first
part of my Invention, a rotating stop N may be employed, which is geared to revolve
so slowly as to come in contact with a roller N above it, just in time to nearly stop
the sheet a moment. Instead of the roller N a second rotating stop may be used,
and this device may be located on each side of the machine. Instead of a swinging 5
stop to prevent the return of folded papers when pushed on one side by the packer
a revolving stop O may be used. This stop is placed loosely upon a pin and is
turned a quarter revolution with every reciprocation of the packer. A ratchet o
attached to the stop and a pawl o¹ prevent the revolution of the stop in the
opposite direction, and the return of the folded papers. When the roller D is 5
in an elevated position the sheet is fed down to the stops K. The rocking of the
shaft E by the operation of the cam G then drops the roller D and brings it into

page_text: contact with the cylinder B, and the sheet is fed out between them into the rods L
at the same time the stops K are lowered to permit the feeding out of the sheet,
and the discs J are raised and are rotated by suitable mechanism to assist in feeding
the sheet out and preventing it from following around the cylinder C. When the
sheet is fed out the proper distance the shaft E is rocked in the opposite direction,
the roller D is raised and the creaser bends the sheet into the cylinder C as
already described, the discs J being lowered to permit the sheet to be carried
around by the cylinder C. Instead of the discs J short arms or switches J¹
may be employed. The cam G is made in two pieces, which are adjustable upon
each other so as to adapt the feeding mechanism to sheets of different sizes.
The eighth part of my Invention relates to mechanism for delivering the sheets
from the printing press straight without folding, and is illustrated in Figure 13 of
the Drawings.
The direction of the web of paper through the press is shown by the dotted
line 11. A, A¹, represent the cutting cylinders, and B is a cylinder provided with
a recess b to accomodate projections on the cylinder C. The cylinder C is con-
structed of rings and ribs to permit the fly to pass within its periphery. Upon the
surface of the cylinder C are projections c and grippers c¹ similar to those on the
cylinder E described in connection with the first part of my Invention. A fly D is
attached at one end to the rock shaft within the cylinder C. A spring E attached to
the fly operates to hold the latter within the periphery of the cylinder, but the latter
is thrown out at the proper time by means of a cam F on the frame under which
passes a roller d' attached to the fly D. The fly D is also provided with friction
rollers d upon its outer end; G represents another fly provided with fingers, and
attached to a rock shaft g so as to be vibrated up and down. H is a receiving
board, which is supported upon rods h, h. These rods are surrounded by springs
which serve to hold up the receiving board and at the same time permit the latter
to yield as the weight of the paper upon it is increased, thus enabling it to preserve
a proper position for the delivery of the sheets.
In operation the sheet is separated and seized between the two cylinders B and
C, the same as by the cylinders D and E, described in the first part of my
Invention. As the sheet is carried forward by the rotation of the cylinder C, the
fly D is thrown out against the sheet by the cam F, and taps the rear end of the
sheet upon the end of the receiving board; simultaneously the fly G descends upon
the same end of the sheet and retains it upon the board. If desired, this cylinder C
may also be used with a folding cylinder, in which case, however, it must be provided
with movable creasers like those attached to the cylinder B described in the second
part of my Invention. As the circumference of the cylinder C is equal to the length
of four,sheets of paper the devices may be so arranged that the sheets may be
delivered alternately straight upon the receiving board by means of flys, and to a
folding cylinder by means of suitable creasers.
Figure 14 illustrates a method of conveying sheets upon a cylinder by suction.
The cylinders A may be used whenever a cylinder with grippers is required, but in
place of the latter a suction device is used to hold the sheets to the cylinder.
This device consists of suitable bellows a, a, arranged within the cylinder, the
surface of which just over the bellows is perforated. The bellows may be operated
by cams acting on friction rollers a¹, a', attached to the bellows, or by any other
suitable device so arranged that a suction is provided at the proper time for
receiving and holding the sheet to the cylinder and pressure is exerted in a contrary
manner to force the air out at the proper time for releasing the sheet.
