WILLIAM CONQUEST, of Tudor Street, in the City of London, Mechanical
Engineer. "AN IMPROVED MODE OF AND APPARATUS FOR MAKING-UP PRINTED
PAPER INTO THE FORM OF BOOKS, PAMPHLETS, MAGAZINES, OR NEWSPAPERS."
This Invention for making-up printed paper into the form of books, pamphlets,
magazines, or newspapers may for the sake of easy illustration be conveniently
described as applied to a continuous web printing machine, in which the ordinary
four page and eight page newspaper sheet of the present day is printed. It consists
in arranging the position of the pages of typo or stereotype plates on the type
cylinders in a peculiar manner, and combining therewith cutting, piling, pasting,
and folding mechanism.
The parts are so arranged that the paper is, (1), printed on both sides and cut
and piled in open eight page sheets; (2), eight page sheets are printed and cut, and
then slit in two and folded, the result being two four page sheets; (3), the apparatus
will also print and cut eight page sheets, then slit them in two and pile in an open
state the resulting four page sheets; (4), the apparatus will print, cut, paste, and
fold together two four page sheets to form an eight page sheet.
To print one side of an eight page sheet four pages of type or stereotype plates
are required, but the type cylinders of this machine are therefore made large enough
to take on it a duplicate form, that is eight pages, two pages in length and four pages
in circumference, with the columns of type in these pages, or stereotype plates
running parallel with the axis of the cylinders.
The cutting cylinders for cutting the web into sheets are one half the diameter

page_text: of the type cylinders, because the length of paper printed at each revolution of the
type cylinder must be cut by them into two sheets.
The piling and folding mechanism consists chiefly of a cylinder that receives the
sheets from the printing machine, and as accessories to this cylinder there is a set of
fingers in the cylinder to seize and carry around the front edge of the sheets a
set of moveable tapes to aid in carrying the sheets around the cylinder; a set of
switches to discharge the sheets from the cylinder to the piling apparatus, and a
folding blade in the cylinder, constructed and operated in the manner described in
a Patent granted to the present applicants dated September 4th, 1875, No. 3105, to
enter the sheets into the folding device. A pasting apparatus for pasting or gumming
the sheets is provided, consisting of a narrow roller or disc running in a trough of
paste or gum, and a carrying roller consisting of one or more discs running in
contact therewith: These rollers or discs are raised or lowered into or out of
contact with the paper to be pasted by means of cams or other automatic mechanism,
so that the sheet of paper when folded will adhere at certain margins only.
A cylinder constructed and arranged in the above manner will servo, (1), as a
collecting cylinder that will collect on its surface two or more sheets, and then by
means of the switches discharge them to the piling apparatus to be piled in an
open state; (2), as a folding cylinder to fold sheets of paper by the folding blade
forcing them into or between the folding rollers; (3), as a combined collecting and
folding cylinder, by first collecting two or more sheets and then entering them
together into a folding roller or device; (4), as a combined collecting, pasting, and
folding cylinder, by collecting two or more sheets and presenting them to the
pasting device, so as to receive paste or gum at the desired margin, and then
enter them into the folding mechanism, so that when folded they will adhere
together.
In illustration of the above if it be required to print and pile open an eight page
sheet, then two pages or stereotype plates are placed side by side at each end of the
cylinders, their abutting heads together at the centre in the usual manuer. As these
four pages will cover but one half the circumference of the cylinders a duplicate set is
similarly placed on the other half. The cutting cylinders being but half the
diameter of the type cylinders, the paper will be cut into sheets of four pages on
each side, making eight page sheets. These will be carried to and caught by the
fingers of the collecting cylinder until (say) six sheets are collected on it, when they
will be discharged in a body to a sheet flyer that will pile them open ou a table as
is done by the well known "Hoe" web printing machine.
If it be desired to print a four page sheet then four sets or pairs of pairs of pages
or stereotype plates are put on the printing cylinder, two pairs side by side at cach
end. The paper is printed and cut into sheets of eight pages each which_are
collected on the cylinder as before, but as they are discharged to the sheet flyer
they pass by a circular saw that slits them in two, and the two half (or now
four page) sheets are piled open as in the case of the eight page sheets described
above.
To fold four page sheets the pages of type or stereotype plates are placed on the
type cylinders in the position last described, and the eight page sheets are received
..on the collecting cylinder as before, but the discharging switches of this cylinder
are now thrown out of action, and the folding blade is brought into operation, so
that this cylinder now becomes a folding cylinder. The sheets as they are received
are caught by the fingers and carried around until (by the folding blade) they are
made to enter into the folding mechanism. A circular saw is so arranged as to cut
the sheets either before or after this first fold into two four page sheets, which
may be conveyed by other suitable mechanism to another folder in order to be
further folded.
To fold an eight page sheet the set of four pages of type or stereotype plates are
placed in a row around one end of the type cylinders with the columns running
parallel with their axes as before, and a duplicate set around their opposite ends.
The paper when thus printed and cut from the web will form eight page sheets the

page_text: two ends of which will be duplicates of each other. These sheets will also be in
pairs, that is, the alternate sheets will be duplicates of cach other. The folding
blade of the cylinder is now by suitable mechanism made to operate at each
second revolution only of the cylinders, so that when the first sheet of the pair
reaches it, it is not folded but passes around the second time. The pasting apparatus
may now if desired be brought into operation, and the first sheet in passing around
will receive a line of paste or gum along the margin just where the line of folding
should take place. As the sheet passes around the second time it receives the
second sheet of the pair on top of it, and the folding blade forces the two sheets
together into the bite of the folding rollers. These sheets may be slit in two (before.
or after being folded) by a similar circular saw, and these double or eight page sheets
are then conveyed to be further folded by a similar apparatus to that before described
for the single sheets.
The object in placing the forms on the type cylinder with the columns running
parallel with their axes is to cause the sheets to issue sideways from the printing
machine for these reasons, (1), an eight page sheet thus worked can be easily cut
into two four page sheets; (2), no change is required in the sheet flyer in order to
pile an eight page sheet or two four page sheets; (3), when the sheet is cut into
two four page sheets these are in a proper position to receive their first fold by tho
folding cylinder; (4), when the eight page sheet is made of two four page sheets
collected one on the other it is not only convenient to be printed, but it is cut apart:
at the head margin and is folded in the same manner and in the same folding
apparatus as the four page sheets.
It is of course of no importance which way the columns run, provided the sheet.
issues from the printing machine sideways, for in a sixteen page sheet the columns
would run around the cylinders, nevertheless the sheet thus printed would be
in a proper position to be piled or folded whole or in halves as before described.
If it be desired to have the facility of increasing or, diminishing the size of an.
eight or four page sheet by increasing or diminishing the number of its columns,
then the columns of the pages must run around the type cylinders, the circumference
of which will be the length of two pages placed end to end, while their length
must be sufficient for two pages placed side by side. The cutting cylinders are of
the same diameter as the type cylinders, and are provided with two cutting devices
placed diametrically opposite to each other, and they are so arranged as to be easily
thrown out of action.
To arrange the machine for printing eight page sheets the four forms for cach
side of the sheet are to be placed on the cylinders as above described, and one of
the cutting devices is thrown out of operation. The sheets will then issue from
the press endways, and will be collected and piled open precisely in the manner
already described, except that they will not require to be slit in two through the
centre unless two sheets be worked together in breadth.
In order to print in this machine four page sheets, the pairs of forms are placed
side by side on the cylinders, the pairs on the opposite side of the cylinders being
duplicates of these. Both cutting devices are then to be brought into operation,
but one of them is so adjusted as to only partially cut across the sheets, but is not
sufficient to make them separate at this point during the collecting and piling
operations, thus the printed sheets will be piled as eight page sheets, but may be
easily torn apart by hand into four page sheets.
In order to paste and fold eight page sheets, a pasting disc revolving in a reservoir
of paste or gum is mounted just beneath the centre margin of the sheets in their
passage to the folding cylinder.
As only one half of the length of the sheets requires to be pasted, the printed
sheets are pressed into and out of contact with the pasting disc by means of a guide
placed above and below the sheets, and which at the proper time raises and depresses
them.
The folding cylinder is provided with a central groove which extends around it,
and the folding blade is also cut away at that point, so that the paste on the sheets,

page_text: will not touch either of them. As the blade of the folding cylinder forces the sheets
between the folding rollers, and the two halves of the sheets come together the line
of paste will cause them to adhere. As they issue from these first folding rollers
they are conducted by tapes over a second pair of rollers until they strike a stop.
This second pair of rollers is placed at right angles to the first pair, and a folding
blade forces the once folded sheets into their bite; from these rollers the sheets are
again conducted off by tapes. One of the tape or folding rollers has a groove cut
around it just inside the stop, and into this groove a small rotating circular saw is
made to enter. As the sheets run out this circular saw cuts off a strip from the first
folded edge, and thereby cuts the sheets into pages.

the said William Conquest in the Great Seal Patent Office on the 30th May

WILLIAM CONQUEST, of Tudor Street,, in the City of London, Mechanical
Engineer. "AN IMPROVED MODE OF AND APPARATAS FOR MAKING-UP PRINTED
PAPER INTO THE FORM OF BOOKS, PAMPHLETS, MAGAZINES, OR NEWSPAPERS." A
communication from abroad by Stephen Davis Tucker, of New York, in the United
States of America.
This Invention for the sake of easy illustration will be first described as applied
to a web printing machine for printing the ordinary four page and eight page news-
papers of the present day. It consists in arranging the pages of type or stereotype
plates on the type cylinders in a novel manner so that the continued web of paper
when printed may be cut into sheets, which may be collected, piled, pasted, and
folded by mechanical means.
By means of the improved apparatus I am enabled (1), to print on both sides, cut
off, and pile open, eight page sheets; (2), to print, cut off, and pile open, four page
shects; (3), to print, cut off, paste, fold, and cut into leaves eight page sheets; (4), to
print, cut off, and fold four page sheets.
The piling, pasting, and folding mechanism consists mainly of a cylinder that
receives the sheets from the printing machine, or cutting or delivery cylinders, and
of accessories to this cylinder. These accessories comprise principally a set of fingers
in the cylinder to seize and carry around the front edge of the sheets, a set of
moveable tapes to aid in carrying the sheets around the cylinder, a switch to discharge
the sheets from the cylinder, a folding blade in the cylinder to cause the sheets to
enter into the folding device, a pasting apparatus for pasting or gumming the sheets
so that when folded they will adhere at certain margins. The accessories will cause
the cylinder to serve (1), as a collecting cylinder that will collect on its surface two
or more sheets, and then by means of the switch discharge them to a piling apparatus
in order to be piled in an open state; (2), as a folding cylinder to fold sheets of paper
by causing a blade to force them into a folding device; (3), as a combined collecting
and folding cylinder, by first collecting two or more sheets and then causing them to
enter together into a folding device; (4), as a combined collecting, pasting, and fold-
ing cylinder by collecting two or more sheets and presenting them to a pasting
device to receive paste or gum at the desired margin, and then causing them to enter
into a folding device, so that when folded they will adhere together. Also several
modifications of the above process that will be herein-after explained.
In web printing machines in which one form covers the whole circumference
of the type cylinders the size of the sheets cut from the web of paper can be
varied in but one direction, and that is in the direction of the length of the type
cylinders, or in other words, in the width of the web. From this it is evident that
in order to have the facility of increasing or diminishing the size of the newspaper
by lengthening or shortening the length of its columns, the number of pages remain-
ing the same, the columns of the type or of the stereotype plates must run length-

page_text: ways of the type cylinders, and this will be designated in the following description
as system A; per contra, to have the facility of increasing or reducing the number
or width of its columns the columns of type or of stereotype plates must run around
the cylinders, and this will be designated as system B.
As the position of the pages on the type cylinders and the cutting, collecting,
piling, pasting, and folding mechanism will differ materially in the two cases I will
now describe the operation of system A, that is, in which the columns of the pages
run lengthways of the type cylinders. It must be understood that the pages of typo
or stereotype plates on one cylinder are for printing one side of the web, and those
on the opposito cylinder are for printing its opposite side.
Also; let it be understood that the pages herein referred to as being placed on the
type cylinders may be type, stereotype, electrotype, engraved blocks, on plates,
designs on stone, or zinc, or any other printing surface whatever. The circum-
ference of these cylinders must be sufficient to take on four pages placed side by
side, and their length suitable for two pages placed end to end and abutting together
at the centre.
For printing, cutting, and piling in an open state an eight page sheet two pages
are placed side by side at each end of their respective cylinders, their heads abutting
together at the centre in the usual inanner, and these four pages will form a set for
printing one side of the sheet, as shown at Figs. 42, 43, 44, and 45, which represent
the paper printed at one revolution of the type cylinder. As these four pages will
cover but one half of the circumference of the cylinders a duplicate set is similarly
placed on their other half.
The cutting cylinders for cutting the web into sheets will bo of half the size of
the type cylinders, or in certain cases they may be of the same diameter as the type
cylinders and furnished with two cutting devices at opposite points of their circum-
ference, and so arranged as to be casily thrown out of action so that the length of
paper printed at each revolution of the type cylinders must be cut by them into two
sheets having four pages on each side, thus forming eight page sheets that will issue
from the press sideways. These will be carried to and caught by the fingers of the
collecting cylinder, which is of the usual size, and retained on it until, say, six sheets
aro collected, when they will be discharged in a body to a sheet. flyer that will pile
them in an open state on a table as is done by the well known "Hoe" web printing
machine.
If it be desired to print and pile in an open state a four page sheet then four sets
or pairs of pages, cach pair duplicate of the other, are put on the respective type
cylinders, two pairs side by side at each end, see Figure 43. The paper is printed
and cut into sheets of eight pages each which are collected on the cylinder as before,
but as they are discharged from the sheet flyer they pass by a circular saw that slits
them in two, and the two half or now four page sheets are piled in an open state as
in the case of the eight-page sheets described above.
To print and fold four page sheets the pages are placed on the type cylinders in
the position last described, except that their heads instead of abutting together at
the centre of their cylinders all point in one direction, and the eight page sheets are
received on the collecting cylinder as before, see Figure 44. But the discharging
switch of this cylinder is now thrown out of action and the folding blade is
brought into operation, so that this cylinder now becomes a folding cylinder.
The sheets as they are received are caught by the fingers and carried around
until they are caused by the folding blade to enter between the folding rollers, on
issuing from which they may if desired be again folded in the same direction.
circular saw cuts the sheets either before or after these folds, the latter preferred,
into two four page sheets, which may be conveyed off to be further or cross folded
either by a folding cylinder or any other device.
A
To print and fold eight page sheets the set of four pages are placed side by side
in a row around one of their respective type cylinders and a duplicate set around
their opposite ends with their heads all pointing in one direction, see Fig. 45.
paper when thus printed and cut from the web will form eight page sheets, the two
The

page_text: ends of which will be duplicates of each other, and these sheets by reason of the
position of the pages on the cylinders will form alternately the inside and outside
sheets of an eight page newspaper, and as such will be folded together. To perform
this operation the folding blade of the cylinder is by suitable mechanism now made
to operate at each second revolution only of the cylinder, so that when the first or
inside sheet of the paper reaches it it is not folded, but by the aid of a set of swinging
tapes passing around a second time. But now if desired the pasting apparatus
is brought into operation and the first sheet in passing around receives a line
of paste or gum along the margin just where the folding should take place.
As the sheet passes around a second time it receives the second or outside sheet of the
paper on top of it and the folding blade now forces the two sheets together into the
folding device. They are slit in two by the circular saw before mentioned cither
before or after being folded, each half being now a complete double or eight page
sheet, and these may be further folded by the same apparatus as before described for
'the single sheets.
The pasting device consists of a paste fountain furnished with a roller which
revolves to bring up the paste, and a scraper to scrape off the excess the same as in an
ordinary ink fountain.
The transverse pasting blade is simply a strip of metal fixed to arms mounted on
a shaft placed parallel to the folding cylinder, and which revolves turn for turn with
the latter, and as the cylinder revolves the blade comes alternately in contact with
the supply roller in the fountain from which it receives a charge of paste, and then
with the paper to which it transfers the paste. The pasting blade may make any
number of complete turns to one revolution of the cylinder, but in that case its
shaft must run in bearings that have a slight rising and falling or oscillating motion
so as to bring the blade into contact with the paper on the cylinder only at the
proper time.
As the line of paste must be applied to the centre cross margin of the
sheet the pasting blade will come in contact with the first sheet on the collecting
and folding cylinder nearly on a line with the leading edge of the folding blade.
As the folding blade lies slightly below the surface of its cylinder the pasting blade
naturally forces the paper slightly into this cavity, but the centre margin of the
second sheet never reaches the pasting blade, for it is forced together with the first
sheet into the bite of the folding rollers through which they are drawn and caused
by the paste to adhere together, while the pasting blade at the second revolution of
the cylinder strikes into the now vacant space occupied by the folding blade. The
paste may be applied to the sheets at any point in their passage to the folding
device and to either side of the sheet as may be required, or it may be omitted
altogether.
If now it be desired to have the facility of increasing or diminishing the size of
the newspaper by increasing or diminishing the number or width of the columns
then (as previously stated for system B) the columns of the pages must run around
the type cylinders, the circumference of which will be the length of two pages placed
end to end, and their length sufficient for the width of two pages placed side by
side.
The cutting cylinders are of the same diameter as the type cylinders, and are
provided with two cutting devices placed diametrically opposite to each other, and
they are so arranged as to be easily thrown out of action.
For printing and piling in an open state eight page sheets the four pages for each
side of the sheet are placed on their respective cylinders, as just described, with
their heads abutting together, see Figure 46, and one of the cutting devices is
thrown out of operation. The sheets will thus issue from the press sideways, and
be collected and piled in an open state precisely in the manner already described in
the former case, where they issue from the press sideways.
For printing and piling in an open state four page sheets the pairs of pages are
placed side by side on their cylinders, the pairs on the opposite side of the cylinders
being duplicates of these (see Fig. 47). Both cutting devices are then put in
operation, but one of them is so adjusted as to only partially cut across or perforato

page_text: the sheets, but not sufficient to make them separate at this point during collecting
and piling; thus, they will be piled as eight page sheets, but may be easily torn
apart by hand a quantity at a time into four page sheets.
For pasting and folding eight page sheets, the pages are placed on the type
cylinders, and the sheets cut off the same, as just described, for flying in an open
state eight page sheets (see Fig. 4S). A pasting disc revolving in a reservoir of
paste or gum is placed just beneath the longitudinal centre margin of the sheets in
their passage to the folding cylinder. As only one-half of the length of the sheets
requires to be pasted they are pressed into and out of contact with the pasting disc
by means of a guide placed above and below the sheets, which at the proper time.
raises and depresses them.
The folding cylinder has a central groove around it, and the folding blade is also
cat away at that point, so that the paste on the sheets will not touch either. As
the blade of the folding cylinder forces the sheets between the folding rollers the
two halves of the sheet come together, and the paste causes them to adhere. As
they issue from these rollers they may be again folded in the same direction, or
they may be conducted direct over another pair of rollers until they strike a stop.
These rollers are placed at right angles to the previous ones, and a folding blade
forces the partially folding sheets into their bite, and they are again conducted off
by tapes. One of these rollers has a groove cut around it just inside the stop, and
into this groove the cutting edge of a small circular saw is inserted, and as the
sheets run out this saw cuts off a strip from the first folded edge, and thus cuts the
sheets into leaves. Of course the pasting can be omitted if desired.
Another manner of placing the pages on their cylinders for printing by system B,
and folding the sheets, is to point the heads of the pages all in one direction around
their cylinders, as in Figure 49, instead of having them abut together, as in the
preceding case. The cutting cylinder may be one-half the size of the type cylinders,
or they may be of the same size, and then be provided with two cutters at points
opposite to each other, so that the paper will always be cut into four page sheets.
The collecting and folding cylinder will be of one-half the size of the type
cylinders.
For folding eight page papers two four page sheets will be collected on the
cylinder, the first one received being the inside sheet, and the succeeding one tho
outside sheet, and these are folded together at every second revolution of the cylinder.
into the nip of the folding rollers, and from thence are conveyed off to be further
folded, as already described for system A. Of course paste may be applied, as in
the preceding case.
i
For printing and folding four page sheets by this metho the type cylinders must
have two pairs of their respective duplicate pages, so that now all the four pages
sheets will be duplicate, as in Figure 50. The collecting and folding cylinder is
then arranged to fold at every revolution, so that it becomes a folding cylinder only,
and the four sheets as they are received are folded singly.
The foregoing description of printing, cutting, piling, pasting, and folding. paper
refers principally to eight page sheets, and the same cut in two to make two half
sized or four paged sheets, but it is equally applicable to sixteen page sheets in place
of the eight page sheets. Suppose it be required to work a sixteen page sheet of
the same size, then each page above referred to on the type cylinders would be.
replaced by two pages of about one-half their size, and the length of the large pages
would be the width of the two small ones, and the columns in these would naturally
run at right angles to those in the large page (see Figures 51, 52). This sheet can be
printed and folded by either system A or B, according as it may be desired to
increase or diminish its size by altering the length of the pages or their width, as
heretofore explained. The position of the pages in the two systems may be
changed in relation to each other to suit the manner in which the folds are made.
The foregoing description has thus far referred to folds made across the sheets, that
is, at right angles to their line of travel, but sheets ordinarily are also cross folded, that,

page_text: is, folded parallel to their line of travel, and it is very necessary that eight page
sheets and half or four page sheets should be thus folded in the same machine.
It has been already described in both systems A and B that eight page sheets
may be formed of two four page sheets, an inside and an outside one, collected one
on the other, and thus receive their first and perhaps also a second parallel fold
together, the folding blade of the combined collecting and folding cylinder being
then inoperative at every second revolution of the cylinder, but while folding four
page sheets singly the folding blade folds a sheet at each revolution. It follows
from this (1), that both eight page and four page sheets as they issue from the
folding rollers are of the same size; (2), that there will be twice as many four page
sheets as eight page oues; (3), that by reason of the fold the sheets have just
received their breadth is reduced one-half, and consequently a wide space is left
between the successive sheets. These sheets are directed by a movable switch, the
eight page sheets singly, and the four page sheets by two's alternately, into one of
two inclined passages, whose length is slightly less than the breadth of the sheet.
These passages lead the sheets to pairs of rollers and tapes travelling at nearly half
the speed of the folding cylinder, and these tapes receive and convey the sheets to
folding devices to receive a fold at right angles to the one just given, as described
in English Letters Patent granted to me, No. 3019, July 26th 1876. As soon as
the first one of the four page sheets is caught by the receiving or slow moving tapes
its speed is reduced nearly one-half, while the second one is moving at full speed,
and consequently by the time its leading edge has reached the receiving tapes it
has nearly overtaken the first one, and both now travel at the same speed at a
slight distance apart until they reach their respective stops, when the folding blade
strikes and forces them side by side into the nip of the folding device. The space
between the two sheets depends upon how much the second sheet has gained on the
first one, and this is governed by the respective speeds of the delivering rollers and
the receiving tapes. The stop for the first sheet may be a stationary one, but the
stop for the second sheet must be a movable one, so that by means of a cam it will
drop below the path of the first sheet as it passes, but will rise quickly in the space
behind it, so as to be in position to receive the second sheet. The next two sheets
will by the action of the switch enter the other passage, and be conveyed to and
folded in another folding device in a manner similar to that just described.
The eight page sheets enter the two passages alternately the same as the pairs of
four page sheets, and of which in fact the eight page sheets are formed. These are
caught by the receiving tapes, and may be arrested at either the first or second
stop, and are cross folded the same as the four page sheets.
It will be seen from the foregoing that the action of the switch and cross folding
blade and the number of strokes are precisely the same whether folding four or
eight page sheets. The cross folding may be done by a revolving or a reciprocating
blade, and any number of additional folds may be given to the sheet.

This Invention relates to the delivering mechanism of printing machines, being
especially adapted to that class known as "web perfecting," in which a web of paper,
passing between two sets of type and impression cylinders, is printed upon both its
surfaces, and on passing between a pair of cutting cylinders, the printing web is
divided into sheets of an appropriate size; printed sheets are thus produced with
such great rapidity that an apparatus operating with like speed is required to
deliver them.
This Invention consists in an improved delivering mechanism in which is embodied
a delivering cylinder that receives the sheets from the printing machine, and also
includes the accessories to such cylinder. These accessories consist of a set of
fingers to seize the front edges of the sheets, also tapes to aid in carrying the sheets
around with the cylinder, and a switch to discharge the sheets from the cylinder,
also a folding blade to cause the sheet to enter into a folding device; pasting
devices for pasting and gumming the sheets are also included, so that when the
sheets are folded they will adhere at certain margins. These accessories will cause
the delivering cylinder to serve,-
First. As a collecting cylinder that will gather or accumulate two or more sheets
successively one upon the other on its surface, and then discharge them in a singlo
body therefrom to'a piling apparatus which will pile them open or flat.
Second. As a folding cylinder to fold sheets by a folding blade, which will cause
them the enter into a folding device.
Third. As a combined collecting and folding cylinder, which will first collect two
or more sheets, and then cause them to enter together into a folding device.
Fourth. As a combined collecting, pasting, and folding cylinder which will collect
two or more sheets, present them to a pasting device to receive paste or gum at the
desired margin, and then cause them to enter into a folding device, so that when
folded they will adhere together.

Many other features are involved in this Invention, but need no preliminary
mention since they are set out at length in a clear and precise manner in the
following description
--
This Invention is capable of being used in connection with any form of printing
machine, or with any sheet furnishing or feeding mechanism, but it is especially
adapted to be connected with a continuous web perfecting printing machine, which
the web is severed into sheets either before or after being printed; such a machine
contains two type, and two impression cylinders, and a cutting mechanism, but as
its structure is well known, and forms no part of this Invention, the last type and
impression cylinder only are shewn in the Drawing.
The paper is illustrated as being passed between the last type cylinder 100 and
impression cylinder 99, and its being directed from thence between a pair of cutting
cylinders 97 and 98, the former of which is furnished with a cutting blade 95 which
engages in a slot 94 cut in the periphery of the cylinder 98; in passing between these
cutting cylinders the web is severed or partially severed (as the case may be) upon
the lines which are to divide it into sheets. These cutting cylinders are geared
together by toothed wheels 90, 91, the latter gearing with a toothed wheel 92 on
the impression cylinder 99, and this last wheel gearing with a toothed wheel 93 on
the type cylinder 100. The cutting cylinders are of a circumference equal to the
length of the desired sheet, while the type cylinder has an arca equal circum-
ferentially to the length of two sheets, and longitudinally to the length of one or
two sheets, as may be desired; the purpose of which relative sizes of the cutting
and type cylinders will be more fully herein-after set out.
The delivering cylinder 30 is mounted in suitable journals in the framework, and
carries a driving toothed wheel 86 at one end, which is connected through a train
of similar wheels 87, 88, 89, with the toothed wheel 91 on the lower cutting
cylinder; notion may be imparted to the shaft of the delivering cylinder 30, as is
shewn in the Drawings, or to the shaft of either the cutting, type, or impression
cylinders. Endless carrying tapes are stretched to conduct the sheets severed by the
cutting cylinder to the delivering cylinder 30. The upper series 61 of these tapes are
stretched from the roller 31 over the upper surface of the delivering cylinder 30
around a roller 33, and returned through guides 63 over a supporting roller 32 to
the roller 31. The lower series 62 of these tapes pass from the roller 34 over the
roller 35 in contact with the upper surface of the receiving cylinder 60, thence
under a roller 36, and return to the roller 34. These tapes receive motion from the
delivering cylinder 30 and receiving cylinder 60, which are geared together by toothed
wheels 5, 6, and as the delivering cylinder 30 is somewhat larger than the cutting
- cylinders, the surface speed of these tapes is rendered greater than that of the
cutting cylinder; the result of which is that a sheet partially severed by the
cutting cylinders will when nipped between the upper tapes and the surface of the
delivering cylinder, have its speed of travel accelerated to such a degree that it will
be torn on the partially severed line from the end of the web, thus producing a
space 41 between the rear end of such sheet and the forward end of the web.
This severance of the sheet provides room for the entrance of the grippers and
switches between the sheets, as will be readily understood. When however the
cutting cylinders entirely sever the webs into sheets, each sheet as it is nipped
upon the delivering cylinder is advanced rapidly to produce the space 41 between
cach successive shect; in this latter case conductors extending into grooves in each
should bridge the space between the cutting cylinder and roller 31, 34.
A third set 64 of endless tapes are stretched around the receiving cylinder 60 and
a roller 65, which latter is supported upon a shaft GG hung in arms 67 fast upon a
shaft GS; this shaft GS is connected by an arm 69 with a rod 70 by which the roller
65 and the tapes 64 may be held up against the delivering cylinder 30, as in
Figures 4, 16, 17, 18, and 21, or be rocked down from that position, as is shewn in
Figures 15 and 22, as may be desired, the purpose of which will herein-after appear.
This rod 70 (Figures 1 and 21) is bifurcated at one end to straddle the type cylinder
shaft 71, upon which is a cam 72 which bears upon, a friction roller 73 carried by

page_text: the rod 70, and thus rocks the roller 65 and the tapes 64 which it carries into the
position before described. This is a series of switches 7 hung upon a shaft 42 between
the delivering cylinder 30 and the receiving cylinder 60, which shaft 42 is rocked
by means of an arm 43 and connecting rod 44, the latter being bifurcated at its
lower end to straddle shaft 20 of the cam wheel 46 (Figures 2 and 19) and pro-
vided with a pin 45 entering the cam groove 47 cut in the face of the wheel 46.
This cam wheel 40 is rotated by pinion 48 fast on the shaft of the delivering
cylinder 30 which gears with its toothed periphery.
A set of fixed guides 108 are set above the switches to guide sheets from the
roller 35 and from the switches 7 to the roller 32.
The delivering cylinder 30 is supplied with grippers 10 working through a
recess in the same, which are fast upon a shaft hung in the ends of the cylinder.
This shaft carries an arm 21, one end of which is supplied with a friction roller 22,
which runs upon a cam 23 fixed to the framework, the other end being supported
by a rod 24 hung in an eye 25 on the cylinder head and seated upon a spring 26,
the grippers being thus operated as is common in printing machines.
A fly frame 27 supported upon a shaft 28 scated in suitable brackets in the
framework is automatically vibrated at proper intervals by means of a rocking
arm 49, which connects the shaft 28 with a spring seated rod 50; the movements
of the shaft 28 being governed by a rocking arm 29 and a rod 19, which is
bifurcated to straddle the shaft 20, and provided with a stud or pin 2 bearing upon
the face of a governing cam 51 fast on the shaft 20. Thus equipped, the delivering
cylinder 30 is capable of receiving sheet after sheet, which accumulate one on the
other upon its surface to any predetermined number, which are delivered in a body
therefrom and deposited by the fly frame upon the piling table. This function of
the cylinder is in itself well known, but in order that the operation of the
delivering cylinder 30 may be readily understood it will now be briefly described.
The roller 65 is moved forward by means of the rod 70, so as to stretch the tapes 64
against the periphery of the cylinder 30, as in Figures 16, 17, 18, and 21, being locked
in that position by means of a key, which extends through an opening 38 in the
rod 70, and into a recess in the side frame of the machine, or in any other con-
venient manner.
The leading end of the sheet carried forward by the tapes 61, 62, is presented
beyond the roller 32 in such a position over the delivering cylinder that the
grippers 10 which are opened (Figure 37) by their arm 21 riding over the higher
part of the cam 23 and closed as the arm descends upon the lower part of the cam,
in which latter movement they bear down upon and seize the forward end of the
sheet (as in Figure 4), secure the sheet upon the cylinder and cause it to be laid
thereon as the rotative movement of the cylinder proceeds. Each sheet is thus
seized and held upon the cylinder by the grippers from the point occupied by the
roller 32 to that occupied by the roller 65; and just after the head of a sheet has
entered between the tapes 64 and the periphery of the delivering cylinder 30
the grippers begin to open (Figure 17) in order to be in position to seize the next
sheet received upon the cylinder, as in Figure 21. The sheet thus released is pro-
pelled onward by the pressure of the roller 65, and is guided by the tapes 64. At
the point where the tapes 64 leave the delivering cylinder 30 and pass on to the
receiving cylinder 60 the switches 7 are so placed that when in the position shewn
in Figure 21 they will act as guides for directing and holding the sheets upon the
delivering cylinder 30, the guides 108 performing a like service. The delivering
cylinder in its rotation carries the leading end or head of the sheet thus held upon
it under the tapes 61, at the roller 32, reaching which another sheet received from
the printing machine will be laid upon the first, which has been seized by the
grippers and treated in like manner as was the first upon which it is laid. Any
convenient number of sheets may thus be superposed upon the delivering
cylinder 30; and when the predetermined number (four in the machine illustrated)
has been collected the switches 7 are automatically shunted; so that their points
are entered behind the sheets and into recesses 4 cut in the surface of the

page_text: As the
cylinder 30, as in Figure 16, whereby the curved back faces of the switches are
brought so as to coincide with the periphery of the receiving cylinder 60.
grippers 10 release the body of accumulated sheets the heads or leading edges of
the same will be guided by the switches 7 up over the receiving cylinder 60 and
between it and the tapes 62, by which the body of sheets will be conducted down
before the fly frame 27, which fly frame will be automatically vibrated to deliver
the four sheets in a single body upon the piling table. While this body of sheets
is thus passing off the cylinder to be delivered, a single sheet from the printing
machine will be received and seized by the fingers 10 upon the delivering
cylinder 30, as in Figure 16; and when the tails of the body of sheets that are
being delivered from the cylinder 30 pass the point occupied by the end of the
switches 7 the switches will be automatically rocked into the position shewn in
Figure 17, so that the single sheets shall be conducted around the cylinder. The
points of the switches 7 when in the position of Figure 17 enter grooves in the
periphery of the receiving cylinder 60, and the grippers 10, which when opened
project beyond the periphery of the cylinder 30, ride through these grooves.
It will be apparent that the fly frame and switches must be operated so as to
vibrate once to every four revolutions of the delivering cylinder 30. It is also
apparent that such gearing may be so supplied in operating these several parts as
to cause the delivering cylinder to gather or accumulate any particular nuinber of
sheets; six however are found to be a desirable number, since that quantity may be
accumulated upon the delivering cylinder 30 in the time occupied by the ordinary
vibration of a fly frame.
It has been said that the gathering cylinder is not per se a novelty, but such
cylinder when combined and operating as is herein-after set forth, and when
supplied with certain mechanisms now to be particularly referred to, constitutes a
novelty.
In all former arrangements of mechanisms for retaining a number of sheets upon
a gathering cylinder the entire circumferential area of such cylinder has been pro-
vided with guards for retaining the sheets thereon, that is to say, such guards are
Bupplied from the point of reception to the point of delivery as will hold or support
the sheets upon the cylinder. The gathering cylinder herein illustrated is provided
with grippers 10, which may seize the sheets at the point of reception, videlicet, just
beyond the roller 32, and will hold the same securely upon the cylinder until the
point of delivery is reached, videlicet, at the switches 7. It is therefore apparent that
the guards formed by the tapes 61 between the rollers 32 and 33, and by the tapes
54 between the roller 65 and the switches 7 may be omitted, and that the grippers
10 will seize the sheets and carry them away with the cylinder until the switches 7
are reached, when the grippers will release and deliver the sheets to the switches,
which in the position shown in Fig. 16 will by their front pieces guide and deliver
them before the fly frame as they are driven onward by the action of the roller 65.
Thus the gathering cylinder provided with grippers requires no guard for retaining
the sheets upon it from the point of reception (roller 33) to the point of delivery
(switches 7). But as there is necessarily a considerable space between the switches 7
and the roller 32, over which the sheets will not be surely directed without the aid
of a guide, such a device is provided in the guard plate 108, one face of which
coincides with the curved surface of the cylinder, and the other provides a support
for the incoming sheet from the roller 35 to a point near the periphery of the
cylinder 30.
The tapes between the rollers 32, 33, are however advantageous, since they
prevent the tail end of the sheet from flying off from the cylinder, as does also the
guard plate 105. The tapes 64 are also of great advantage, as they hold the sheet up
against the cylinder after it is released by the grippers, and thus propel its forward
end. Hence when these tapes are omitted the propelling roller 65 should be
retained.
=
The delivering cylinder 30 is also supplied at one point of its periphery with a
shaft 39 hung in suitable supports in the cylinder, which shaft carries folding

page_text: blades 40, 52, held upon it by suitable arms 8, 9. This shaft protrudes through
one of the heads of the cylinder, and is supplied with projecting arms 11, 12, (see
Figures 5 and 6), which carry respectively friction rollers 13, 14, through the
medium of which arms semi-rotations are imparted to the folding blade shaft by
means of a flying cam and stationary cam, as will now be explained.
The stationary cam 16 is secured to the framework, as in Figure 11, and the flying
cam 15 is securely hung upon the end of the shaft 17, which is journalled in the
side frame as in Figures 11 and 12. This shaft 17 has fastened upon it a toothed
wheel 18, which gears with a similar wheel 53 fast upon the shaft 20 of the
delivering cylinder. These gear wheels 53 and 18 have an equal number of teeth
(Figures 11, 12) whereby the flying cam 15 is caused to make one revolution in
concert with a like movement of the delivering cylinder, the result of which is
that the flying cam is brought into the position shewn in Figure 13 at the time
when the friction roller 14 on the arm of the folder blade shaft is in the position
therein shewn; and as the cylinder 30 moves in the direction of its arrow the
flying cam will be moved in the direction shown by its arrow, so that as these
rotations proceed their constantly changing positions will be such as to cause the
curved face of the flying cam to be brought upward, and form between it and the
upper. curved surface of the stationary cam 16 a guideway, which will direct tho
friction roller 14 into the central portion or greatest depressed part of the stationary.
cam, as in Figure 15, at which time the point of the flying cam will be directly
'over the friction roller 14, while the friction roller 13 on the arm 11 of the folding
blado shaft will overlie the base of the flying cam. As the rotations proceed the
point of the flying cam 15 will be carried past the friction, roller 14, and its opposite
side will form a guideway for directing the roller 14 out from the stationary cain 15.
By this operation of these devices the folding blade shaft will be gradually
revolved so as to project the flying blade from the cylinder, and cause it to enter
between folding jaws formed (in the instance illustrated) by rollers 33, 54, and
when the blade has reached its greatest protrusion from the cylinder 30 it will
stand between the folding jaws in the position shewn in Figure 15, from which
position it will be gradually withdrawn into the cylinder, the path of travel which

from the position shewn in Figure 13 through that illustrated in Figure 15, into that
shewn in Figure 14, where it is held by the spring detent 107, whose rounded end
enters a shallow recess in the shaft.
It will be observed that the blade 14 now lies in the rearmost position, while. -
that 13 is in the advanced position, and the latter will of course be the blade which

automatically projecting a folding blade outward from a revolving carrier and.
between folding jaws, and withdrawing the samne into the carrier to be carried
thereby, and at the proper time again brought to and projected with the folding
jaws, forms in itself no part of the present Invention; being fully described in the
Specification of a Patent, No. 3105, granted to me, and dated September Fourth,
1875.
When it is desired to convert this delivery mechanism into a folding apparatus
which shall receive the sheets successively upon the surface of the cylinder and
fold then transversely the cam 72 is removed, and the connecting rod 70, Figure 21,
is released so that its spring 74 will draw it back to rock the roller 65, and with it
the tapes 64 into the position shewn in Figures 15 and 22, where they are of no
effect, since the forward end of the sheet which is being folded is not required to
be guided by them when it is released by the grippers. The switches may be thrown
out of operation or be allowed to act, since the sheet being folded does not reach
the point occupied by them. Thuз equipped each sheet directed by the tapes 61,
62, on to the cylinder 30 is seized by the grippers 10 held upon the cylinder and
carried around with it until released, during which time the middle of the sheet
will overlie the folding blade.

page_text: The grippers 10 will commence their opening movement to release and render
free the head of the sheet just as or a little before the folding blade begins its out-
ward movement to carry the middle of the sheet between the folding jaws formed
by the rollers 33, 54.
The outward movement of the folding blade draws the leading end of the sheet
backward, and doubles its middle into the grip of the folding rollers 33, 54, which
in consequence of their rotation carry it out between them in a folded condition.
The rollers 33, 54, are geared together by toothed wheels 75, 76, the wheel 75
meshing with the toothed wheel 5 on the cylinder 30, and the two thus rotated
with a surface speed uniform with that of the surface movement of the cylinder 30.
The mechanism thus arranged is capable of imparting one fold to each sheet, and
delivering it from the folding rollers 33, 54; it may then receive further manipu-
lation, as will be explained.
In order to adapt this mechanism to collect two or more sheets, and simultaneously
fold and deliver the same (the object being to collect separate sheets which together
form one complete newspaper), the following arrangement is made:-Supposing two to
be the number of sheets desired to be thus treated a flying cam and proper gearing,
such as is illustrated in Figures 9, 10, and 28, is substituted for that last described
and illustrated in Figures 11, 12, and 27, and like it is carried upon a shaft 17
supported in journals in the framework, and provided with a toothed wheel 18,
which gears with a toothed wheel 53 on the shaft of the delivering cylinder. The
toothed wheel 53 in this instance has three teeth to each two provided upon the
toothed wheel 18, whereby the flying cam is caused to make one and one-half turns
to every one of the delivering cylinder. If, however, more than two sheets are to
be first collected and afterwards simultaneously folded these toothed wheels must be
proportioned so as to cause the flying cam to make two or three turns to each one
of the delivering cylinder, as will be described.
In this operation of collecting two sheets in succession it is apparent that the
first must be directed around the cylinder, so as to receive the second upon it, but
that when the two are superposed, and their leading ends are released from the
gripper so that they may be carried through the folding rollers, the leading end
must be kept free from engagement with the means which direct the first sheet
onward with the cylinder when the grippers release it. To this end the rod 70,
which is attached to the shaft carrying the roller 65, which supports the tapes 6-4,
is brought into operation by adjusting the cam 72 upon the shaft 71 which can is so
shaped as to reciprocate the rod 70 at every second revolution of the delivering
cylinder.
The switches 7 are made inoperative, that is, they are kept in the position to
continuously guide the sheets around with the cylinder 30 for the reason that none
of the sheets are to be directed to the fly frame. This is done in the present
instance by detaching the arm 44 by unloosening the screw 65 (see Figures 2 and 19).
It might be accomplished by making the pin 45 screw threaded, so as to be readily
turned in and out of engagement with the cam groove 47.
The pasting mechanism (yet to be described) are also made inactive by being
thrown out of action by detaching their driving wheels. Thus equipped one sheet
will be delivered to the grippers and carried by then around with the cylinder 30.
When the point is reached where the grippers release the sheet the cam 72 will
have rocked the tapes 64 (or if they are omitted the propelling roller 65) into the
position shown in Fig. 21, which tapes or roller will then guide the sheet onward
with the cylinder 30, as hereiu-before explained, and a second sheet will be received
upon it, scized by the grippers and carried on with the cylinder 30. During this
second revolution of the cylinder the cam 72 will have caused the tapes 64 and
roller 65 to be rocked into the position shewn in Fig. 22, so that when the two
sheets are simultaneously released by the grippers their leading ends will be free, as
in Fig. 22. As the cylinder revolves carrying the first sheet upon it, the point of
the flying cam as the folding blade arms pass it, is pointed in towards the centre of
the cylinder 30, as in Fig. 10, thus leaving a free path for the arms of the folding

page_text: blade, and as the cylinder makes its next revolution with the second sheet upon it,
the flying cam will again have made one and a half revolutions, bringing its
point into position to operate the folding blade, as in Figs. 14, 15, 28, and thus
double the two sheets simultaneously into the nip of the folding rollers 33, 54, as
shewn in Figure 22.
The operation of the flying cam and stationary cam in effecting the folding and.
withdrawing movements of the folding blade being the same as has been described
with reference to the folding of each successive sheet it need not be again explained.
To throw the folding blade or blades out of action in a folding cylinder (when
for instance it is to be used as a collecting cylinder to fly the sheets), the flying.
cam may be rendered of noneffect by various mechanical devices. Thus it may be
removed with its shaft, as in Figures 9, 10, 11, and 12, where the cap covering its
journal box is made detachable by screws 77; either of the driving toothed
wheels 18, 53, might be removed by means of their holding screws 78, or the flying
cam 15 might be fixed upon the face of its toothed wheel 18, and the two be
adapted to slide freely on the shaft 17 passing out of aud into gear with the driving
toothed wheel 53, according as the cam is in or out of working position, as in
Figure 38. The flying cam may be held constantly forward in its working position,
and the driving toothed wheel 53 made to slide upon a splined shaft into and out
of gear with the toothed wheel 18 of the flying cam, as in Figure 38.
To readily determine the relative positions of the teeth of these wheels 18, 53,
their pheripheries may be marked with indexes shewing proper points for their
respective teeth to gear, or they may each carry a guard wire or plate 131, cut
away at a certain place which will allow them to be moved out of and into gear at
that place and no other. A stop pin 130 inserted through the framework into a
hole in the cam wheel will prevent its turning when out of action.
Figures 27 to 36 shew modifications of the mechanism for operating the folding
apparatus; Figures 27, 28, and 29, shew the relative proportions of the spur.
gear 18 and 53 required to so place the flying cam 15 as to operate the folding
apparatus every revolution of the cylinder 30, as also every second and every third
revolution of the said cylinder 30. In Figures 30 and 31 the spur wheel 53 is '
twice the breadth of the wheel 18, so as to allow the flying cam 15 to be drawn out.
of line with the bowls of the folding tumbler without being out of gear; this is.
effected by the ground cam 109 which is geared by the wheels 110 and 111 with
the shaft 20 of the cylinder 30. Into the groove 113 of the cam enters one end of
a forked lever 112, the opposite end of which embraces a collar on the short sliding.
shaft 17 of the flying cam which will thus be drawn out of gear and replaced at.
every other revolution of the cam 30. Figures 32 and 33 shew the requisite gear
and cams for operating two folders with either one or two flying cams, and
Figures 34, 35, and 36, shew means for giving a vibrating motion to the flying
cams; 114 is a grooved disc or plate keyed on the shaft 20; a pin 115 on
a lever at the end of the shaft 17 of the flying cam enters this groove, and by this.
means the flying cam 15 will be rocked into position to receive the two folders in
rotation.
This apparatus is provided with longitudinal and transverse pasting mechanisms.
The longitudinal pasting mechanism Figures 1, 40, consists of a disc 133 revolving
in a paste reservoir 126 placed just beneath the longitudinal centre margin of the
sheets in their passage to the delivering cylinder 30. This disk 133 is fast upon a
shaft extended through the side frame and provided with a pulley 117 which is
rotated by means of a belt 118 (see Figure 1), from a pulley 116 on the impression
cylinder shaft. The web or sheets of paper run through a guide having an opening
in its lower plate formed of fingers 124, 125, placed on each side of the paste disc.
The upper member 124 of this guide is fast upon a rocking shaft 122, and the lower
member 125 is fast upon a rocking shaft 123. These shafts 122 and 123 are
connected together by a link 121, so as to move in unison and carry the paper up
away from or down upon the paste disc, as may be desired. This movement is
accomplished by a rocking arm fast upon the shaft 123, operated by a cam 119,

page_text: Figure 7, on the lower cutting cylinder 98 through a connecting rod 120 furnished
with a friction roller, by which devices the paper is raised or lowered at such
intervals of time as may be required to properly paste it longitudinally.
In order to adapt this machine to collect two sheets, paste the same transversely
on the proper margin and fold and deliver them adhering together, the apparatuses
are arranged to collect and fold two sheets as last described, and the transverse
pasting mechanism is brought into action.
The transverse pasting mechanism consists of a paste fountain 57 (see Figure 39),
furnished with a roller 58 revolving to bring up the paste, which roller may be
furnished with a scraper or doctor to remove the excess of paste, as is commonly
done in the ordinary ink fountain.
The pasting blade is a simple strip of metal fixed on a shaft which turns in arms
carried by a rotating shaft 79, Fig. 39, placed parallel with the cylinder 30. The
blade turns independently of the rotative movement of its carrying arms for the
purpose of retarding its movement at the pasting roller, and accelerating it at the
point of its engagement with the delivering cylinder, as will be described. The
shaft 79 carries at one end a toothed wheel 80 meshing with a similar wheel 81 on
a cross shaft 82 (see Figure 1), which receives motion through a toothed wheel 83,
Figure 2, from the toothed cam wheel 46. This latter wheel is driven from the
cylinder 30, and the gearing just described is so timed that the pasting blade is
revolved turn for turn with the cylinder, and as the cylinder revolves this blade
comes alternately into contact with the fountain roller 58, from which it receives a
charge of paste, and with the sheet of paper (carried by the cylinder) to which it
imparts paste.
The fountain roller 58 is intermittently rotated to present to the action of the
pasting blade a surface charged with paste by a ratchet wheel 84 (see Figure 1)
actuated by a pawle 3 carried by an arm 85 rocked by an arm 101 pivoted
excentrically to the face of the wheel 80.
As the pasting blade 59, if allowed to simply rotate and thus sweep over the
surface of the slowly moving fountain roller 58, would gather a large quantity of
paste upon its advanced side and thus smear the paper, the blade is so operated
that as it approaches the fountain roller, which is then stationary, its edge shall be
carried directly against the periphery of the roller, then the blade shall be turned
so as to leave the roller without dragging over any portion of its surface, and when
the blade is thus free from the roller and moves onward in its circular path it is
brought into a position so that its edge shall travel with the same speed as does the
surface of the cylinder 30 or the paper carried by it.
In order to accomplish these movements of the pasting blade, its shaft, which is
made to turn in the arms which carry it, is provided at one end with a rocking
arm 102 which rides upon the periphery of a cam 103 fixed upon the side frame,
and at the other end is provided with a spring which constantly presses the rocking
arm against the cam 103.
As the diameter of the circle described by the paste blade when in its greatest
extended position is less than that of the cylinder 30, and as this blade must move
with the same surface speed as does the cylinder when in co-operation with it so as
to apply paste to the sheet it carries, it follows that the speed of the blade must be
accelerated at that time; and as the fountain paste roller is stationary, or nearly so,
at the time when the blade is carried into contact with it, in order to be charged
with paste, its motion must be such that the blade will not sweep over the surface
of the roller but be carried quickly into contact with and withdrawn from the
same; this is accomplished by rocking the blade in its carrying arms independently
of its circular movement with the shaft 79. When the blade approaches the
fountain roller it stands in the position shewn in Figure 24, with its edge thrown
forward of the centre of its shaft, and consequently carried inward toward the
shaft 79, in which position it stands over the fountain roller. Now the shape of the
cam is such that as the shaft continues its circular movement the rocking arm will
move and swing the blade backward, so that it will stand in allignment with its

page_text: carrying arms and be extended its greatest distance from the shaft 79, at which
time its edge is thrust into contact with the fountain paste roller. As the shaft
further continues its circular movement the cam causes the blade to continue its
rearward movement, thereby raising its edge clear from the fountain roller.
When it has left the fountain roller, as in Figure 26, the shape of the cam 103 is
such as to hold the paste blade in its rearinost position during about one-third of its
circular travel, and when it approaches the cylinder 30 the cam is so shaped as to
turn it gradually forward, causing the edge of the blade to accelerate its motion so
that its movement shall be equal to the speed of the cylinder, passing in contact
with which it applies paste to the sheet, as is seen in Figure 21. When however
the blade has been in its foremost position moved into contact with the sheet its
rocking arm 102 passes over the highest position of the cam 103 until its descends
to the lowest part of the cam, to be again brought into contact with the fountain
roller.
The pasting blade inay make any number of complete turns to one of the cylinder,
but in that case its shaft must run in bearings that have a slight rising-and-falling
or oscillating motion, so as to bring the blade into contact with the paper on the
cylinder only at the proper time. As the line of paste must be applied to the
centre cross margin of the sheet the pasting blade will be brought into contact with
the first sheet collected (as last herein-before described) nearly on a line with the
edge of the leading folding blade, and since the folding blade lies slightly below the
surface of the cylinder 30 the pasting blade will force the paper slightly into
the cavity thus formed (as in Figure 21), but the centre margin of the second slicet
never reaches the pasting blade, for it is forced (together with the first sheet upon
which it has been laid) into the nip of the folding rollers, through which the two
are together drawn and caused to adhere together by the transverse line of paste
applied to the outer surface of the first sheet. The pasting blade at the second
revolution of the cylinder strikes into the then uncovered cavity occupied by the
folding blade, as in Figure 23. The guard 105 will of course prevent the ends of
the sheets that are being folded from dropping down on to the pasting blade.
The pasting apparatus may be located so as to apply the paste to the sheets at
any point in their passage to the folding devices and to either side of the sheet, as
may be required, or it may be omitted altogether.
Instead of collecting the two or more sheets by the operation of the cylinder 30,
as herein-before described, they may be collected by making the first sheet travel a
greater distance than the second, and the first and second a greater distance than
the third, so that they will all meet together, as described in the Specification of
a previous Patent, No. 2561, granted to W. E. Newton, August 28, 1872, and may
be thus collected and carried by the cylinder 30 to the action of the folding devices.
The collection of two sheets (which may be two four page sheets, to form one
eight page paper) by this method is illustrated in Figure 54, where the tapes 61 are
made to pass under a pulley 243 up over a pulley 245, and thence under the
A third set 242 of
pulley 32, being retained in this instance over a pulley 246.
tapes runs over pullies 244 and 245, forming with the tapes 61 a prolonged passage
way, the entrance to which is governed by a switch 251 operated by a cam 252;
the first or outside sheet forwarded by the tapes 61, 62, is directed up into this
prolonged passage way by the switch 251, while the second or inside sheet is carried
directly to the cylinder 30, for the reason that the switch 251 is locked into the
position shewn to so direct it. The first sheet thus travels the longer distance and
emerges from the prolonged passage way, it being directed by the guard 258 just in
time to join the second sheet in the common path and be laid thereon, seized by the
grippers and carried onward, to be folded or doubled by the folding blade into the
folding rollers 33, 54.
An instance of the location of the pasting mechanism so as to operate upon the
upper surface of the sheet is also illustrated in Figure 54, Figure 55 being a rear
elevation of it. It consists of a revolving blade 255, which is so geared as to make
17

page_text: one revolution to every second sheet that passes, and it is so timed that after
taking a charge of paste from the fountain roller 256, above it, it will apply the
same to the centre margin of the alternate or inside sheet. When the two sheets
are brought together by the collecting apparatus last described, the outside one (the
first, which has travelled through the prolonged passage way) falls upon the inside
one, and the two travel on together and are received upon the cylinder and folded
on the pasted margin.
The paste blade 255 is hung by arms fast to a shaft 254 that makes one revolu-
tion to every two revolutions of the delivering cylinder 30, and the diameter of the
circle the paste blade describes is equal to half the diameter of the folding cylinder
30, from which it follows that to make the edge of the blade travel with the same
speed as the sheet while it is in contact with and applying the line of paste thereto,
the velocity of the blade must be increased to four times its normal speed. To effect
this the shaft 254 of the pasting blade is driven by the well-known differential
motion in which the axes of the driven and driver are placed parallel with but
excentrically to each other, and the motion is communicated by a crank pin, as
255 in the one working in a slotted arm, as 253 carried by the other, In this
arrangement in proportion as the speed of the driven (which is the paste blade
255) is augmented in one part of its revolution it is correspondingly reduced in
the opposite part, and advantage is taken of this by putting the paste fountain at
the point of the reduced travel of the paste blade, so that when the edge of the
blade passes the paste roller to receive its charge of paste, it is then moving at the
same speed as the slow running paste roller. The paper while being pasted is
supported by a roller 248, having a longitudinal groove in its surface, and this roller
is driven by gearing, so that the paste blade will always strike over this groove,
thus when (from any cause) there is no sheet upon it to receive the paste the roller
will not be snicared.
In this modified pasting apparatus the driving wheel 250 gears with a similar
wheel 89, which is one of the train connecting the cutting rollers with the cylinder
30. The fountain roller 250 may be slowly or intermittently revolved in like
manner as is the same device in Figure 39. And this mechanism may be arranged
10 be thrown out of action if desired.
The cylinder 30 may be constructed of a series of pullies set a distance apart
upon a common shaft, thus providing between their edges openings corresponding
with the grooves 4 and 134, and this cylinder may be driven by other gearing
than that shewn, for instance, mitre gears and a shaft connecting it with the shaft
of the type or impression cylinder.
The several rollers which carry tapes as well as the folding rollers may be pro-
vided with reduced peripheries at the points occupied by the tapes, or instead of
being continuous might be composed of a number of pullies fixed upon a common
shaft.
The folding rollers may be placed at any other point of the periphery of the
cylinder 30, a lower position being sometimes advantageous.
Moreover, though folding rollers are herein shewn it is obvious that the folding
blade may be projected into jaws formed by longitudinal strips or bars, in which
case a reciprocating frame work carrying grippers might advance, seize the folded
sheet and withdraw and deposit it upon a piling table or over another set of
folding devices.
Though the folding blade herein shewn is composed of two blades secured at points
opposite to each other on a common shaft, it is obvious, since only one of said blades
acts at a given time at the folding jaws or rollers, that a single blade only is required,
but if that construction be adopted, then the single blade, after the folding operation is
completed, in which it is turned into a rearward position, may, during its circular
travel around, to again co-operate with the folding jaws, receive a semi-rotation so
as to be brought into proper position by means of a flying cam placed in the inside
of the cylinder 30.

page_text: Furthermore, though grippers have been described as a means for carrying the
sheets around with the cylinder 30 it is practicable to omit them.
As the once folded sheets issue from the folding jaws or rollers 33 or 5+ they
may be again folded in the same direction, or they may be conducted direct over
another pair of rollers until they strike a stop. These last rollers are placed at
right angles to the previous ones, and a vibrating or revolving folding blade forces
the once folded sheets into their bite, and the resulting twice folded sheets are
again conducted off by tapes. One of these rollers may have a groove cut
around it, just inside the stop, and into this groove a small circular saw revolves,
which as the sheets run out cuts off a strip from the first folded edge, and thus
cuts the sheets into leaves.
The mechanisms and their operations as thus far described are adapted to the
manipulation of printed sheets of any width, equal to or less than that of the
type and cutting cylinders, and of a length equal or nearly so to the circum-
ference of the cutting cylinders. If that is the size of the sheets to be mani-
pulated, of course the type cylinder need be no larger than the cutting cylinders,
but as has been stated the type cylinder has an area circumferentially equal to the
length of two sheets, and longitudinally equal to the width of one or two sheets,
as may be desired.
If it is desired to print and fold the ordinary four or eight page newspapers of
the present day the pages of type or stereotype plates may be arranged on the type
cylinders in such positions as to adapt the printing, cutting, collecting, piling, pasting,
and folding mechanisms comprised in this apparatus to,-
First. Print on both sides, cut off, and pile in an open state or flat eight page
sheets.
Second. To print, cut off, and pile in an open state or flat four page sheets.
Third. To print, cut off, and fold four page sheets.
Fourth. To print, cut off, paste, fold, and cut into leaves eight page sheets.
In continuous web printing machines in which one
"form covers the whole
circumference of the type cylinders the size of the sheets cut from the web of paper
can be varied in but one direction, and that is in the direction of the length of the
type cylinders, or in other words, in the width of the web. From this it is
evident that with a type cylinder of a given diameter in order to have the facility
of increasing or diminishing the size of the newspaper by lengthening or shortening
its columns, the number of pages remaining the same, the columns of type or of
the stereotype plates must run lengthways of the type cylinders, and this will be
designated herein as system A; per contra, to have the facility of increasing or
reducing the number or width of its columns the columns of type or of stereotype
plates must run around the cylinders, and this will be designated as system B.
As the position of the pages on the type cylinders and the cutting, collecting,
piling, pasting, and folding mechanisms will differ materially in the two cases the
operation of system A (that is in which the columns of the pages run lengthways of
the type cylinders) will first be described.
It must be understood that the pages of type or stereotype plates on one cylinder
are for printing one side of the web, and those on the opposite cylinder are for
printing its opposite side.
Also let it be understood that the "pages" herein referred to as being placed on
the type cylinders may be type, stereotype, electro-type, engraved blocks or plates,
designs on stone or zinc, or any other printing surface whatever. The circum-
ference of these cylinders must be sufficient to take on four pages side by side, and
their length suitable for two pages placed end to end, and abutting together at
the centre.
For printing, cutting, and piling in an open state or flat eight page sheets, two
pages are placed side by side at each end of their respective cylinders, their heads
abutting together at the centre in the usual manner, and these four pages will form
a set for printing one side of the sheet, see Fig. 42, which represents the paper
printed at one revolution of the type cylinder. As these four pages will cover but

page_text: one half of the circumference of the type cylinders a duplicate set is similarly placed
on their other half.
The cutting cylinders for cutting the web into sheets will be half the size of the
type cylinders, as in Fig. +1; or, in certain cases, they may be of the same diameter
as the type cylinders, as in Fig. 56, and furnished with two cutting dences at
opposite points of their circumference, as in Fig. 41, one or both of which are so
arranged as to be easily thrown out of action. This may be done by simply
removing the cutting blade, or by withdrawing both the cutting blade and its
actuating shaft. Or if the construction shewn is used, then, since the motion of the
vibrating arm which is derived from the cam groove 139 which vibrates its rocking
arm is quite short, the cutting blade may be rendered inoperative by removing the
friction roller from the arm, as is represented in Figure 41. This done the cam
groove will have no effect upon the arm, and the cutting blade will not be pro-
truded from the cylinder. When one cutter only operates, and its carrying cylinder
is one-half the size of the type cylinder the length of paper printed at each
revolution of the type cylinders will be cut in the line o, Figure 42, into two sheets,
having four pages on each side, thus forming eight page sheets that will issue from
the press sideways. These will be carried to and caught by the fingers of the
cylinder 30, which is of the usual size, collected and retained upon it until, say, six
sheets are accumulated, when they will be discharged in a body or mass to the
sheet flyer 27, which will pile them open or flat on a table, as is done by the well-
known "Hoe" web printing machine.
If it be desired to print and pile in an open state a four page sheet then four sets
or pairs of pages, each pair duplicates of the other, are put on the respective type
cylinders, two pairs side by side at each end, with their heads to the centre, as in
Fig. 43. The paper is printed and cut into sheets of eight pages, each of which is
collected on the cylinder as before, but as they are discharged from the sheet flier
they pass by a circular saw or cutter 106 adapted to be thrown into action against
or projected into a groove in the cylinder 60, which slits them longitudinally on the
linc o, o, into half sheets, or now four page sheets, which are piled open, as in the case
of the eight page sheets herein-before described.
The web is
To print and fold four page sheets the pages are placed on the type cylinders in
the position last described, except that their heads, instead of abutting together at
the centre of the cylinders, all point in one direction, as in Fig. 44.
cut on the line o, and the eight page sheets are received on the cylinder 30 as
before; but the discharging switch of this cylinder is now thrown out of action, and
the folding blade is brought into operation, as has heretofore been described, so
that this cylinder now becomes a folding cylinder. The sheets as they are received
are caught by the fingers and carried around until they are successively entered by
the folding blade and folded on the line x between the folding rollers, on issuing
from which they may, if desired, be again folded, either in the same direction or at
right angles thereto." A circular saw like that 106 may be arranged to cut these
sheets longitudinally, that is on the line o, o, either before or after these folds (the
latter preferred) into two four page sheets, which may be conveyed off to be further
or cross folded.
To print and fold eight page sheets the set of four pages are placed side by side
in a row around one end of their respective type cylinders, and a duplicate set
around their opposite ends with their heads all pointing in one direction, as in
Fig. 45. The paper when thus printed and cut from the web on the line o will
form eight page sheets, the two ends of which will be duplicates of each other, and
these sheets, by reason of the position of the pages on the type cylinders, will form
alternately the inside and outside sheets of an eight page newspaper, and as such
will be folded together on the lines x, x, x. To perform this the folding blade
of the cylinder is by the mechanism shewn in Figs. 10, 11, 28, 29, now made to
operate at each second revolution only of the cylinder, so that when the first or
inside sheet of the paper reaches it, it is not folded, but by the aid of the swinging
tapes 64 is carried a second time around the cylinder 30, in the manner herein-

page_text: But
before described for collecting two sheets and simultaneously folding the same.
now, if desired, the transverse pasting apparatus is brought into action, and the
first sheet in passing around the cylinder 30 receives a line of paste or gum along
the margin x, x, just where the fold is to be made. This pasting may be
accomplished by either of the transverse mechanisms herein-before described,
whereby the first sheet will be pasted, the second laid upon it, and the two carried
by the cylinder 30 within the range of action of the folding blade, which now forces
the two sheets together on the lines x, x, x, into the folding device. The folded
sheets are slit in two on the line o, o, (either before or after being folded) by the
circular saw before mentioned, each half now being a complete double or eight pago
sheet, folded and cut into leaves.
If now it be desired to have the facility of increasing or diminishing the size of
the newspaper by increasing or diminishing the number or width of its columns,
then, as previously stated for system B, the columns of the pages must run around
the type cylinders, the circumference of which will be the length of two pages placed
end to end and their length sufficient for the width of two pages placed side by sido,
sce Figures 46 to 50. The cutting cylinders, or it may be only the cylinder
carrying the cutting blades, are of the same diameter as the type cylinders and are-
provided with cutting devices placed diametrically opposite each other and arranged
so as to be easily thrown out of action, as has been described; or with one cutting:
blade 95 (see Fig. 56) and one perforating blade 270.
This latter may be constructed to be inserted and removed from the cylinder 97,-
or be operated therein as are the cutting blades shown in Figure 41. Its teeth aro
arranged, as shewn in Figure 57, whereby the cut it makes will only partially divide
the web, as in Fig. 58, which is thus left just strong enough to undergo mani-
pulation in folding and piling but weak enough to be readily separated by slight
force.
For printing and piling open eight page sheets, the four pages for each side of the
sheet are placed on their respective cylinders, as just described, with their heads
abutting together (see Fig. 46) and one of the cutting devices is thrown out of
operation. The sheets will thus issue from the press endways, and be collected and
piled open precisely in the manner already described in the former case where they
issue from the press sideways.
For printing and piling open four page sheets the pairs of pages are placed side
by side on their cylinders, the pairs on the opposite side of the cylinders being
duplicates of these (see Fig. 47). One of the cutting blades in the cylinder 97 is
then removed and a perforating blade 270 adjusted in its place, as in Figure 56.
The cylinder 97 will then partially cut or perforate the sheets on the line o, o, but
not sufficiently to make them separate at this point during collecting and piling;
thus they will be piled as eight page sheets but may be easily torn apart on the
perforated line o, o, by hand, a quantity at a time, into four page sheets.
For pasting and folding eight page sheets the pages are placed on the type
cylinders, and the sheets cut off the same as just described for flying open eight
page sheets (see Figure 48). The longitudinal pasting mechanism is now brought
into action, and as only one half of the length of the sheets requires to be pasted,
namely, that portion indicated by the dotted lines x, x, x, x, they are pressed into
and out of contact with the pasting disc 133 by the guide arms 124, 125, between
which the sheets run, which raises and depresses them at the proper time.
The delivering cylinder 30 has a central groove 134 around it and the folding
.blade is also cut away at the point 132, so that the longitudinal line of paste on
the sheets will not touch either as the blade of the folding cylinder forces the sheets
between the folding rollers the two halves of the sheet will be folded together on
the line x, and the line of paste will cause them to adhere; of course, the pasting
can be omitted if desired.
Another manner of placing the pages on their cylinders for printing by system B,
and folding the sheets, is to point the heads of the pages all in one direction around
their cylinders instead of having them abut together as in the preceding case, see

page_text: Figure 49 and 50.
The cutting cylinders may then be one-half the size of the ty
cylinders or they may be of the same size, and provided with two cutters at poin
opposite each other, as before described, so that the paper will always be cut
the line o into two four page sheets. The collecting and folding cylinder will be
one-half the size of the type cylinders.
For folding eight page papers these two four sheets will be cut apart on line
Figure 49, and collected on the cylinder, the first one received being the inside she
and the succeeding one the outside sheet, and these are folded together at ever
second revolution of the cylinder into the nip of the folding rollers and from thend
are conveyed off to be further folded, as already described for system A, paste bein
applied on the line x, x, by the longitudinal parting mechanism, or omitted as i
the preceding case.
For printing and folding four page sheets, by this method the type cylinders mus
have two pairs of their respective duplicate pages, so that now all the four pag
sheets will be duplicates which are to be cut apart on line o, see Figure 50. Th
collecting and folding cylinder is then arranged to fold at every revolution so tha
it becomes a folding cylinder only, and the four page sheets as they are received are
folded singly.
The foregoing description of printing, cutting, piling, pasting, and folding paper
refers principally to eight page sheets, and the same cut in two to make two hal
size or four page sheets, but it is equally applicable to sheets of sixteen or other
numbers of pages.
In place of the eight page sheet suppose it be required to work,
say, a sixteen page sheet of same size, then each page above referred to on the type
cylinders would be replaced by two pages of about one-half their size and the
length of the large pages would be the width of the two small ones, and the
columns in these would naturally run at right angles to those in the large page, see
Figures 51, 52. This sheet can be printed and folded by either system A or B,
according as it may be desired to increase or diminish its size by altering the length
of the pages or their width, as heretofore explained. The positions of the pages in
the two systems may be charged in relation to each other to suit the manner in
which the folds are made.
The sheets emerging from the folding rollers 33, 54, have folds made across them,
that is, at right angles to their line of travel. But sheets are also ordinarily cross
folded, that is, folded parallel to their line of travel, and it is very necessary that
eight page sheets and half a four page sheet should be thus folded in the same
machine. It has been already described in both systems A and B that eight page
sheets may may be formed of two four page sheets, an inside and an outside one
collected one on the other and thus receive their first and perhaps also a second
parallel fold together, the folding blade of the combined collecting and folding
cylinder being then inoperative at every second revolution of the cylinder, but
while folding four page sheets singly the folding blade folds a sheet at each revolu-
tion. It follows from this (1), that both eight page and four page sheets as they
issue from the folding rollers are of the same size; (2), that there will be twice
as many four page sheets as eight page ones; (3), that by reason of the fold the
sheets have just received their breadth is reduced one-half, and consequently a
wide space is left between the successive sheets. These sheets are directed by a
movable switch operating in connection with the folding rollers, the eight page
sheets singly and the four page sheets by twos alternately of one of two inclined
passages, as in my former Patent of One thousand eight hundred and seventy-six.
From these inclosed runners the sheets are directed to the folding or flying mechanism.
Having now described the nature of the said Invention and the means of carrying
the same into effect, wish it to be understood, that under the above in part recited
