Improvements in Letter Press Rotary Printing and Folding
Machines.
1, JULES DERRIEY, of 81 Avenue Philippe Auguste, Paris, France, Engineer,
do hereby declare the nature of the said invention to be as follows:-
The object of my invention is a rotary letter press printing and folding machine
which can be readily adapted for printing various sizes of sheets, not only those
like the daily newspapers, but work requiring to be carefully printed, such as
illustrated papers, book and other work usually printed in machines having a
reciprocating type or "form" bed, working at a slow speed.
According to my invention, I print from a roll or web of paper which is cut into
sheets of the required length, and is fed to the rotary cylinder printing mechanism,
and is then delivered and piled so that if required the printed matter may be
different for each alternate sheet, the sheets then being piled separately without
being folded or the sheets as printed are folded and then piled, either in one or two
separate piles and after being folded one, two or three times as required.
Newspapers printed upon rotary machines have been folded but the folding
which is effected in such machines, is not sufficiently correct for illustrative papers,
book and other work, as it is by my invention.
In carrying out my invention, I make the cylinders for the type or stereo form
and the impression cylinders, of double the size required by the largest sheet to be
printed, and each type or stereo plate cylinder carries two type forms upon it, so
that two sheets of the largest, or of lesser size may be printed at one revolution,
and these type forms are adjustable circumferentially in relation to each other,
and each impression cylinder has two impression surfaces and two sets of
grippers.
I arrange when required that the printed sheets may be delivered singly or in
twos, viz., one superposed over the other.
By my machine at each revolution of the type and impression cylinders two
different forms of the same size of sheet may be printed.
In carrying out my invention, the paper to be printed upon is drawn from a roll
or web, passes over spreading and tension rollers, and between two feed rollers,
then between a pair of perforating or cutting cylinders, which are arranged to cut
the paper into separate sheets of the required length.
The sheets thus severed from the roll of paper are carried forward by endless
tapes round a cylinder and the forward edge of each sheet in succession is
carried and directed into one of two sets of grippers upon an impression cylinder
which presses it against the type cylinder which is inked by ink supply distributing
and conveying rollers in the usual manner.
The first set of grippers upon the first impression cylinder delivers the sheet
printed on one side to the first set of grippers on a second impression cylinder
which carries the other side of the sheet against the second type or form cylinder
inked in like manner to the first type cylinder.
The second set of grippers on the first impression cylinder take the forward end
of the second sheet which is printed by the second type form on the first type
cylinder, and is then delivered to the grippers of the second impression cylinder
and is printed by the corresponding type form on the second type cylinder.
The sheets when printed on both sides are taken from the grippers of the second
impression cylinder by a receiving cylinder having one set of grippers which
cylinder is half the size and makes two revolutions to one of the type and impression
avlinders

page_text: This receiving cylinder may when required take two sheets of the same kind in
succession superposed one over the other.
The receiving cylinder delivers the printed sheets to two other cylinders each
having two sets of grippers, the grippers of one of these two cylinders passes the
sheet or sheets to the other cylinder, or these two cylinders are used as folding
cylinders, the first cylinder having two adjustable knife blades each for pressing
the middle of the sheet into one of two sets of adjustable pincers carried upon the
second cylinder.
The sheets are or may be passed from the two transmitting cylinders or trans-
mitting and folding cylinders to endless tapes by which they are carried to one or
two oscillating "Hys." If the sheets are all to be piled together one "fly" only
operates but if each alternate sheet is to be piled separately the two "flys" act
alternately to make two separate piles of the printed sheets.
If the sheets are to be folded one or more times cross-ways they are carried by
endless tapes between two cylinders, the axes of which are parallel to each other,
and at a right angle to the folding and transmitting cylinders first mentioned, and
a knife blade which has movement given to it radially by cam action forces the
middle of the sheet into grippers in the cylinder below it, and from this cylinder
the sheets are or may be carried by endless tapes, to two piling "flys" to be piled
in one or two piles as required.
Or the last named cylinder carries an adjustable knife blade, to push the middle
of the sheet into the grippers carried upon a third cylinder, and from this the
folded sheet is carried by endless tapes to a trough, and is pushed along it, (the
flat side of one sheet against the other) by an oscillating arm which acts to push
the folded sheets all one way as required or the alternate sheets in opposite
directions in the trough in which the folded sheets are "piled" edge upwards.
The grippers and pincers are actuated by cams in an ordinary manner and the
printing impression and folding cylinders and "flys" are all geared to work
⚫ together.

Improvements in Letter Press Rotary Printing and Folding
Machines.
I, JULES DERRIEY, of 81 Avenue Philippe Auguste Paris, France, Engineer,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention relates to rotary printing and perfecting machines into which the
paper to be printed, is fed in the continuous or web form, but is cut into sheets of
the desired length before being printed, and after printing the sheets are delivered
singly, and unfolded and piled, or they are or may be folded once, twice or three
times, or one sheet is superposed upon another and the two sheets are then delivered
and piled unfolded or folded, two, three or more times, or several sheets are
superposed, and then delivered and piled.
My improved machine is more especially designed for what is commonly termed
in England "jobbing work," that is, say for work superior to that required for
ordinary newspapers, such as illustrated papers, railway time tables, or book work,
in other words, it is designed for such class of printing as is generally effected upon
what are termed perfecting printing machines, which have the type, stereotype, or
electrotype secured upon a reciprocating flat bed.
To meet the requirements of "job printing" the machine must be capable of
printing any size of sheet which is smaller than the largest size of sheet for which

page_text: the machine is made. For this reason it is necessary to cut the web of paper fed
to the machine into the required lengths before being printed. It is not novel to
cut the web fed to the machine into sheets before being printed, as I patented such
system in England in 1888, and erected in England rotary machines for cutting
before printing in 1878 and in 1885, but in these cases the machines were made for
common newspaper work, printing one sheet only at each revolution of the
printing cylinders, and they delivered the printed sheets, either unfolded or folded
three times.
My improved machine, the subject of this Specification (as before intimated) is
not designed for common newspaper printing, though it may be used for such
purpose, but less advantageously than other rotary printing machines designed
specially for printing common newspapers.
The defects of rotary printing machines in which the web is cut into sheets
before printing are the insufficiency of the inking arrangements and the liability to
"creasing to which the sheets are subject.
"
Creases of the sheet in printing common newspapers are, and may be tolerated,
but are very objectionable in printing engravings or illustrated and other book-
work.
To obviate the defects above referred to, my machine is made with printing
cylinders of large diameter, as the larger diameter of the printing surface (being
of less curvature) and the nearer its surface approaches that of the flat type
bed printing machines and the better is the work that is produced.
In order to obtain a printing surface of large diameter and to utilize_such large
cylinders in rotary web printing machines cutting before printing; I make the
printing cylinders and the impression cylinders of double the diameter necessary to
print one sheet of the largest size, and so that each cylinder has two printing
surfaces, the impression cylinders having two sets of grippers, and two impression
surfaces, in order that one side of two sheets may be printed at cach revolution
of the cylinders.
The two printing surfaces or "forms upon each cylinder may be duplicates or
the forms or matter of each printing surface may be different, consequently, two
impressions of the same matter, or two impressions of different matter can be
made at each rotation of the printing and impression cylinders upon the same
size of sheet.
66
When printing different matter by each printing surface the sheets when
'perfected "will have to be delivered and piled in single sheets upon separate
tables, and this is done either unfolded or folded as often as required, or they are
delivered two sheets together, either open or unfolded, or folded as often as
required.
When required, my improved machine may be used for printing upon one side
only of each sheet; in this case the second printing cylinder is put out of action,
and of contact with the second impression cylinder, which then acts simply as a
transferring cylinder.
My invention will be most readily explained and understood by reference to the
accompanying drawings.
Fig. 1 is a longitudinal section and elevation of the feeding and printing end of
my improved machine up to the dotted line - but including the whole of the
small gripper cylinder through the axis of which that line passes.
Fig. 1 is the continuation of the longitudinal section and elevation, shown by
Fig. 1, of my improved machine at the delivery end, from the dotted line x-

the axis of which that line passes being also shown in Fig. 1ª as well as in
Fig. 1.

shown by Fig. 1, and in this modification, the small single gripper cylinder shown in
Fig. 1, is replaced by a large gripper cylinder having two sets of grippers, as herein
after explained.
Rotary web printing machines cutting before printing, being well known; the
mode of feeding the web of paper, cutting it into lengths, carrying it by tapes or
cords to grippers of the impression cylinder, the construction of gripper and
impression cylinders, the mode of gearing these together, and in which sheets are
transferred from one set of grippers on one cylinder to the grippers upon another
cylinder, gripper cylinders for transferring and for folding, and tapes or cords for
transmitting partly folded sheets to cross folding cylinders and finally to piling
flyers, piling flyers and the mode of actuating them, printing cylinders, and the
modes of inking them; all these parts, and the ordinary modes of arranging and
working them, are well known, and being so, need not be described and in the
following description, I shall mainly point out the peculiarities in which my
invention differs from ordinary combinations and arrangements of rotary web
printing machines in which the web is cut into sheets before being printed, and give
such other information as may be deemed necessary in order that my invention
may be clearly understood.
I will first describe the mechanism and arrangements by which the paper
carried through the machine, and is delivered and piled, or folded, delivered and
piled when printed, and then the mechanism by which it is printed.
a, Fig. 1 is the roll or web of paper to be printed upon; its end is taken under a
guiding roller &', then over the roller b, for drawing it from the roll, and measuring
the length of paper to be used, at each revolution of the printing cylinders. This
roller b, is driven by gearing and change wheels in order that it may be rotated at
such speed as to give the desired length of paper, which shall be equal to, or less
than, the length of the two sheets required by the largest size of sheet for which
the machine is made, at each revolution of the printing cylinder.
Above the drawing off and measuring roller b, there is another roller 2, the
surface of which is formed by printers' inking composition or any other suitable
elastic material, this roller 2, having its bearings in arms on an axis 63, so that its
weight presses it upon the surface of the paper passing from the web over the
drawing and measuring roller b.
The paper web from the roller b, passes between two cutting cylinders c, and c²,
of ordinary construction; on one cylinder c¹ of which there is a toothed blade that
perforates the entire width of the web when the tooth blade on one cylinder c¹, comes
opposite the space for it, in the other cylinder c, both cylinders being of the same
diameter, and being geared to rotate together as shown by the arrows near them.
They make two revolutions for one of the printing cylinders.
The peculiarity of these cutting cylinders c, and c', is that their circumference is
only slightly (say about half an inch) larger than the longest sheet to be cut by

page_text: them, and this size is adopted so that the knife may not draw the paper too much,
especially when cutting the smaller sizes of sheets.
The peripheries of the cutting cylinders do not pinch or press upon the web
passing between them.
The paper after passing the cutting cylinders, is carried on endless tapes or
cords d", to the grippers of the first impression cylinder e, the drag of the tapes
causing the sheet to be detached from the web.
There are endless cords which work on the cylinder c¹, and roller d', slots
being provided in the perforating knife for these cords to pass into, so that they are
not cut.
The lower or carrying side of the upper endless tapes pass from the roller d',
under the large roller d, over the small roller d², under the small roller d³, and then
back to the first named roller d¹.
The upper or carrying side of the lower endless tapes pass from the upper side
of the roller d, under the roller d, to the small roller d', over it, and then return
under the roller do, and over the roller d', to the underside of the roller d.
The endless tapes are driven by being geared with the cutting cylinders c, and c¹,
at the same surface speed for all sizes of sheets for which the machine is designed,
the surface speed of the tapes being that of the printing and impression cylinders so
that the forward end of each sheet severed from the web enters the grippers of the
first impression cylinder at the point at which the grippers are intended to receive
it, and the time of its arrival at the grippers is adjusted by releasing the driving
wheel, and turning the cutting cylinders, and thus the tapes backwards or forwards
as required, and then securing the driving wheel again.
The first impression cylinder, is divided into four parts two parts of its
surface e form the impression or blanket surface, and between these two surfaces,
there are gaps and in each gap a set of grippers e², and arrangements for retaining
and tightening the blanket, the latter not shown.
The front ends of the two sheets fed by the endless tapes for each revolution of
the impression cylinder e, are taken in succession by the two sets of grippers e²,
upon it, and are each carried by it against the first printing cylinder f, one "form"
upon it printing one sheet, and the other "form" the other sheet.
As the grippers upon the first impression cylinder e, come opposite to the grippers
on the second impression cylinder, which is constructed in every respect like the
first impression cylinder e, the forward end of the sheets held by the grippers on
the first impression cylinder are delivered in succession to the grippers of the second
impression cylinder and are by them carried against the second printing cylinder h.
The arrows in Fig. 1 near the impression and printing cylinders show the direction
in which they rotate.
The grippers of the second impression cylinder deliver to a single set of
grippers, upon a taking off cylinder i, of half the diameter of the impression
cylinder, which taking off cylinder i, makes two revolutions to one of the impression
cylinders and 9.
The grippers, on the small cylinder i, deliver the sheet to grippers upon a
cylinder of the same diameter as the impression cylinders e, and which
cylinder, has two sets of grippers j', and this cylinder j, delivers the printed
sheets to another cylinder k, of the same size having two sets of grippers k¹, and
this last cylinder delivers the sheets to two sets of endless carrying tapes dt.
The lower or carrying side of the upper set of endless tapes pass from the
roller, over the cylinder k, to the roller under and over that roller, then under
the rollers 12, and 1³, over the roller l, and back to the roller 7.
The upper side of the lower set of endless tapes pass partly round the cylinder k,
in grooves therein, and over the upper side of the roller 15, to the roller ", under
it, and over roller 2, over roller 1, down to the under side of the roller 16, and
then back to the underside of the cylinder k.
When the sheets have to be piled after leaving the cylinder k, a number of
endless upper tapes are applied between those described, the lower sides of which

page_text: pass from the roller l, over the roller 15, and to and under the roller l, then ascend
to the roller 18, and pass over it, and the roller 1, back to the roller l.
When thus arranged the endless tapes will convey the sheets from the cylinder k,
to and between two sets of endless tapes de, one set working upon rollers 1, and 1º,
and the other upon rollers 17, and 1*.
Near the rollers 19, and 1x, are the axes of one or two flyers m, and m², two are shown
-one flyer m', is shown in a position in which it has deposited one sheet upon the
table n, the other flyer m, is shown in the position waiting to receive the next
sheet, which will be piled on the table n.
When each alternate sheet is different, they are thus piled separately.
When both sheets are alike, one flyer only need be used, but both may be
employed if desired as they will thus work slower than one acting alone.
When sheets are to be crossfolded, the tapes that convey to the flyers m, and m',
are removed, and endless tapes for the lower or carrying side are used, the upper
side of which tapes begin at the upper side of the roller 1, and pass to the upper
side of the roller ", then under it, and over a roller 12, over the roller 18, and back
to the underside of the roller 1, and by these endless tapes the sheets are conveyed
until the forward edge of each sheet comes against a stop which leaves it opposite
to and between the two first cross folding cylinders to be hereinafter described.
Going back to the taking off cylinder i, this cylinder when desired is arranged
to take and hold two or more sheets in succession as arranged, one superposed over
the other.
The manner in which the grippers are made to open after having received a sheet,
in order to receive another sheet upon the first, and the manner in which the sheet
or sheets already within the grippers is retained in its position, while the grippers
open to receive another sheet, and the manner in which the grippers open when the
accumulated sheets are to be delivered or transmitted, is fully described in the
Specification of Letters Patent Numbered 2805 of 1885 granted to John Clayton
Mewburn, as a communication from myself.
When the superposed sheets are delivered by the cylinder i, they are or may be
transferred by its grippers to those of the cylinders j, and k, to be conveyed to the
flyer m, or flyers m, and m'.
But when single sheets or superposed sheets are to be folded there are two knives
or edges, which are adjustable upon the cylinder j, to suit the size of sheet to be
folded and the grippers ', upon the second cylinder k, are put out of action (by
removing the cam operating them) and the knives 2, upon the cylinder j, push the
middle part of the sheet or sheets to be folded into the nippers k², two pairs of which
are arranged on the cylinder k, as shown. These nippers k², are adjusted to the
knives upon the cylinder j, by releasing the axis of the cylinder k, from its
driving wheel, and turning the cylinder k, backwards or forwards as required, and
when adjusted, securing the driving wheel again to the axis of the cylinder k.
It will be understood that when superposed sheets are being transferred from the
small cylinder i, only one knife 2, and one set of grippers j', is required to be used
on the cylinder j, the grippers k', on the cylinder k, not being required, one set of
grippers 2, being used instead, the other sets of grippers not to be used being put
out of operation by removing their cams.
When single sheets from the cylinder i, have to be folded, both sets of grippers,
and the two knives ², upon the cylinder, are used, and the two sets of nippers k²,
on the cylinder k, are used, but the grippers k', are not required when folding.
The cylinder j, is and may be also used as a collecting or superposing cylinder,
each set of grippers j, upon it, receiving two or any desired number of sheets super-
posed upon each other which are then transmitted to the grippers A, of the
cylinder k, and from the latter to the carrying tapes d, and passed on by them to
the flyers m, and m¹.
It should be noted that the small cylinder i, when arranged to do so, superposes
two sheets which are printed in succession which may be different, that is, one may
be the outside, and the other the inside sheet of a newspaper.

page_text: The cylinder j, when so arranged will collect or superpose sheets printed from the
same "form" alternately.
The remarks hereinbefore made in reference to the mode of operating the
grippers and holding the sheets when superposing sheets on the small cylinder i,
are also applicable when superposing by the cylinder j, and sheets superposed by
the cylinder j, may if desired be transmitted to the grippers k, of the cylinder k,
or if to be folded are delivered to the nippers k², on the cylinder k. In either
case the grippers k', or nippers 42, are arranged to be actuated by the cams, or
not actuated at such times as may be required.
It should be noted that the cams acting upon one set of grippers where two
are used upon the same cylinder are upon one side of the machine and those
for the other set of grippers upon the other side of the machine.
It should also be noted that the nippers k², upon the cylinder k, for receiving
the folded sheet or sheets, are actuated to open and close at the times required by
cams, in an ordinary manner.
In Fig. 1 the folding knives, upon the cylinder j, are shown and described
as being adjustable, but instead of being adjustable, they may be fixed, and the
grippers may be made adjustable.
This mode of constructing the cylinder j, is illustrated by Figs. 3 and 4.
In these figures, 13, is the axis of the segments of the cylinder j, j, are arms
secured upon the axis j³, which carry the segments of the periphery of the cylinder j,
and the fixed knives or blades j².
There is an arm ³, at each end of the cylinder, and the boss part of each
arm j, fits upon the exterior boss of the arms j', secured upon the axis or
shaft 3.
These arms j, are movable upon the boss, and when adjusted they are secured
by screws, each of which passes through a concentric slot in the movable arm j³,
and screws into a part connecting two of the arms j, for the cylinder j.
In the ends of these arms jo, the grippers j', and connected parts are mounted and
arranged in the usual manner.
The gap in the periphery of the cylinder ;, between its two segments, allows the
grippers to be moved nearer to or further from the fixed knives or blades j².
When the grippers are adjusted to the folding knives or blades 2, the cylinder j,
may then be adjusted to its position in relation to the grippers upon the small
cylinder i, and the nippers k², upon the cylinder k, may be adjusted to the knives j²,
on the cylinder j, by releasing the driving wheels upon their shafts and turning
the cylinders backwards and forwards accordingly, and then again securing the
driving wheels when adjusted.
I will now describe the cross folding mechanism by reference to Fig. 14 and
Fig. 2.
The tapes by which the sheets are brought between the first two cross folding
cylinders are shown in Fig. 2. The cross folding cylinders have their axes
horizontal and at a right angle to the axes of the cylinders, and k, Fig.
14.
The upper cylinder p, is a plain cylinder with one knife blade, which is
arranged to slide in a slot or guide in a radial line from the axis of the cylinder p.
This blade p', is connected at each end with an arm, which arms are from a
shaft p, having its bearings in the cylinder p, this shaft being actuated by a cam
in the same manner as grippers are worked.
The cam causes the blade ', to withdraw within the radial groove, and then
when the blade comes opposite nippers. 7, in the cross folding cylinder 7,
immediately below it, to push out the blade p', and thus force the middle of the
sheet brought by the tapes, into the nippers q, on the cylinder
below.
If only one cross fold, is to be given to the sheet, it is caused to pass from the
nippers q', to endless tapes de, that convey it to one or two flyers, or ", which
pile the sheet on one or the other of the tables below them.
There are grooves round the cylinder 7, into which shunts or pointed conductors q³,
can enter, which conductors are. secured upon.a shaft in suitable bearings, on the

page_text: framing, which shaft can be slightly oscillated and secured with the points of the
conductors either in the grooves in the cylinder q, and below its general surface
(but not touching the groove or cylinder) or clear of the surface of the cylinder
as shown in Fig. 2.
When the conductors 92, are in the first named position they get under and
between the folded sheet and the surface of the cylinder q, and divert the sheet
from the latter to the endless tapes.
The upper side of what I will call the lower tapes passes over the rollers q³,
under the roller 9, over the roller 9, then descends and passes under the
roller, and ascends from it over the roller q', and under the roller 8, and back
to the roller g³.
The under side of what I will term the upper endless tapes, commences at the
roller s, passes in contact with the surface of the cylinder q, then under the roller q',
over the roller go, then descends to the roller s', and from it ascends over the
rollers, and then passes back to the roller s.
When the sheet received by the nippers q', of the cylinder g, is to receive another
fold, the conductors 2, are away from the cylinder q, as shown, and the sheet held
within the grippers q', is taken round with the cylinder in the direction of the
arrow upon it, and a knife or blade 9, upon the cylinder forces the middle of the
sheet into pincers t', carried upon a third cross folding cylinder t, which delivers
it to endless tapes d', carrying it to one or two flyers w, and u¹.
What I may term the lower side of the lower tapes, pass partly round the
cylinder t, then over a roller t², then descend, and pass under a roller t³, and
ascend and pass over a roller t', and back to the cylinder t.
The lower side of the upper tapes commence say at the roller t³, touch upon the
upper side of the cylinder t, pass over the roller t, then descend and pass under
. the roller t, and ascend to and over the roller t, and then pass back to the upper
side of the roller to.
As a rule the width of the web of paper is constant, but if different widths of web of
paper are to be printed upon, the cross folding cylinders can be adjusted by arranging
the knife or blade q, upon the cylinder.q, so as to be adjustable, and turning the
cylinder t, and setting it, so that the blade 9, will come opposite the nippers t',
carried on the cylinder t.
The nippers q, and t¹, are actuated to hold and release the sheet at the time
required by cams as before stated in respect of the nippers k², in the cylinder k.
The two flye.s u, and u¹ are used when each alternate sheet is to be piled separately
but both flyers may be used when both sheets printed at one revolution of the
printing cylinders are the same, as the flyers will thus work slower, but one flyer
need only be used in such case if desired.
When sheets printed by my improved machine are only required to be delivered
unfolded (termed open delivery) I combine with my machine, only one double
grippered taking off and transmitting cylinder, which may be used either as a simple
transferring cylinder, or for both a superposing and transferring cylinder, which
delivers to endless tapes and to one or two piling flyers.
This modification of my invention is illustrated by Fig. 8, which shows on a
rather enlarged scale the delivery end and continuation of the machine illustrated
by Fig. 1.
This Fig. 8 shows the second impression cylinder g, as combined with the taking
off cylinder j, which is of the same diameter as the impression cylinder g, and is
constructed same as the cylinder j, Fig. 1A but without folding blades j'.
This cylinder, has conductors same as those (92) described in reference to the
folding cylinder q, Fig. 2, the points of which conductors, enter grooves in the
cylinder, and get under and between the sheet to be delivered, and the surface of
the cylinder j, to cause the sheet to pass to endless tapes for conveying the sheet to
piling flyers.
When the taking off cylinder j, is used as a superposing cylinder, each set of
grippers, receives two or any other desired number of sheets to be superposed or

page_text: collected, each set of grippers will receive only sheets from the same printing
surfaces, and when each set of grippers hold the desired number of superposed
sheets, they are then delivered to the endless tapes d.
The conductors q², are lifted away clear of the cylinder, by a cam, while the
sheets are being superposed and are only brought into action as shown in Fig. 8 to
remove the sheets and conduct them to the tapes when they are to be delivered by
the grippers from the cylinder j.
The endless tapes are arranged as follows.
The upper side of one set of endless tapes commences say at the roller v, passes
in contact with and over the upper surface of the cylinder, over the upper surface
of the conductors 92, between the rollers ¹, and v², under the roller v³, then upwards
and over the rollers v, and v³, back to the roller v.
There is a set of tapes commencing say at the upper side of the roller v²,
passing to the roller vx, and over the roller vl, back to the underside of the
roller v³.
There is another set of tapes commencing say at the roller ve, then passing in
contact with the cylinder j, to the roller, under it to the roller 8, ascending
to the roller, touching the underside of the roller v2, and back to the roller v³.
These tapes serve to keep the free end of the sheets passing round the cylinder
in contact with its surface.
The two rollers v³, and vx, have their bearings in arms which have their axes at
each end opposite the axis of the roller v².
These two rollers v³, and vx, are oscillated by a suitable cam in an arc shown in
dotted line from 'the position in which they are shown in full line to that in which
they are shown in dotted line by two dotted circles in Fig. 8.
In the position in which they are shown in full line they direct the sheet to be
delivered between two endless sets of tapes d", conducting to the lower flyer (not
shown) and table y', and in the dotted position they direct the sheets between two
sets of tapes d', conducting to the upper flyer (not shown) and table y³.
The conveying side of the endless tapes for the lower flyer commences say at the
roller w, passes to the left of the roller w', to the right of the roller w², and to the
left of the roller w³, and then to the right of the lower roller w, under it, and
ascend on the right of the roller w³, and left of the roller w, and right of the
roller w, and left of the rollers w², and w³, and then back to the left of the
roller w.
The other endless tapes of the set commences say at the roller w³, passes on the
right of the roller w, on the left of the roller w', and the right of the roller w², and
left of the roller w³, then touches the right of the roller w, and passes under the
roller wx, and ascends passing on the right of the roller w", on the left of the
roller y', the right of the roller w12, and then back to the roller w³.
The sets of tapes for the upper table y³, commence say from the upper side of
the roller Y, and descend and pass on the right and under the roller y₁, and the
return side of the tapes pass on the right of the roller w12, to the right of the
roller w, and back to the roller y.
The other set of tapes pass say from the roller y², on the right of the roller y
then to and under the roller y³, and the return sides of the tapes then ascend and
return directly to the right of the roller y².
The flyers act alternately to pile the sheet or sheets on the tables y*, and y³, from
each set of grippers j', upon the cylinder j.
The construction of the printing cylinders will be explained by reference to
Figs. 5 and 6.
The cylinders, and h, for carrying the curved stereo or electro type plates are
formed by a cylinder marked f, in Figs. 5 and 6 with arms f¹, at its two ends, the
bosses of which arms are bored out to receive the axis or shaft to which the
cylinder f, is secured and upon which it is rotated.
The periphery of the cylinder f, is a plane surface.
There are two separate stereo or electro printing surfaces f², carried upon each
B

page_text: cylinder f, in the direction of its circumference, and the length of the cylinder f,
is divided into two, thus making four sections, for four separate turtles f³, (as they
are termed) and four curved stereo or electro plates f2.
In the middle of the cylinder f, there is a ring, or two segments of a ring f*,
with an inclined under-cut at each side of the ring which is secured by screws f³,
and there is a ring f, at each end having arms, which ring is bevelled or undercut
upon its inner edge where it meets the edge of the turtle, as shown.
Each end ring, can be tightly secured by four screws f, to the arms carrying
the ends of the cylinder f.
The turtles are formed by four separate curved plates f³, the underside of each
plate fits to the periphery of the cylinder f, and rests thereon.
The outer face of the turtles have a series of dovetail grooves f³, parallel with
the axis of the cylinder f, and each end of each turtle 8, is bevelled to fit the
undercut inclines upon the fixed ring or segment of rings, in the middle and the
movable rings f6, at the two ends of the cylinder so that by means of the screws f",
and the rings 6, the turtles f³, are held firmly and truly upon the cylinder f.
The ends of the electro or stereo plates f2, are bevelled as shown in Fig. 5, and
at the middle come close against the heads of under-cut screws f³, and at each end
are secured by under-cut clamps fx, to fit the bevelled end of the stereo or electrof,
each clamp having a dovetail to fit one of the dovetail grooves in the face of the
turtle 3, so that they may be adjusted therein and then secured by one or more
screws, passing through each of them and screwing against the bottom of the
dovetail in the turtle f³.
There is a bar , passing longitudinally on each side of the cylinder f, secured
to it by screws, and upon each side of the bar h', a number of set screws h², are
screwed, the pointed heads of which come against the edges of the turtle f³,
shown in Fig. 6, and thus hold them from moving in the direction in which the
cylinder, rotates.
as
When one printing cylinder f, is adjusted the other 1, may be adjusted to it, so
as to obtain correct "register" by first slackening the rings f, which hold the
turtles f³, and then unscrewing and screwing the screws 12, as required, and then
tightening the rings fe, again when correct register has been attained between the
two printing cylinders f, and h.
c2, is a partition extending between the side frames of the machine, to keep dust
and fibres arising from the unwinding and cutting of the paper from ascending to
the inking rollers and stereo or electros on the printing cylinder f.
"
In rotary printing machines for "jobbing work' it is most important to have
good inking arrangements.
The first printing cylinder (f) is generally arranged to print what is called the
"inner" form, and the second printing cylinder h, the "outer" form, which latter
is more especially devoted to the printing of engravings or illustrations for which
reason the inking arrangements for the "outer "form are made the most complete.
For inking the "inner" form, that is, the first printing cylinder f, there are four
inking rollers, 2, 3, and 2, in contact with the printing surfaces, and these
receive ink from an ordinary ink duct 2, and its roller 1, by means of an ordinary
roller 2, vibrating between the roller 1, in the duct, and the large roller 3, and the
ink is transmitted from the latter through the rollers 4, 5, 6, and 7, (7 being a large
roller) to the two form inking rollers, and 22; from the upper roller, the ink is
conveyed to the other two form inking rollers 3, and 2, by two carrying and inter-
mediate rollers 8 and 9.
The ink transmitting rollers both transmit and distribute the ink, the rollers 3, 5, 8
and 9 having the usual end reciprocating as well as the rotary motion.
Some of the letters and figures of reference used on the inking mechanism for
"forms on
the cylinder f, will also be used on the inking mechanism for the "outer
the second printing cylinder h, which are inked by six inking rollers marked z',
to, supplied with ink from the duct z, and its roller 1, by a roller 2 vibrating
between the duct roller 1 and a roller 10, which transmits to a roller 11, that
i

page_text: transmits to a large roller 3 which transmits directly to two inking rollers z*.
and 22, and from one 22, to another 2, on the same side by an intermediate trans-
mitting roller 8.
The roller 3 that transmits ink directly to two inking rollers z¹, and ², also
transmits ink through three rollers 4, 5 and 6, to a second large roller 7 which
transmits ink directly to two inking rollers 2³, and 2, and from one of them 2*, to a
third inking roller 6, on the same side of the printing cylinder h, by an intermediate
roller 9.
The rollers 10, 5, 8 and 9 have, or some of them have, reciprocating end, as well
as rotary motion.
All the inking rollers for both cylinders f, and h, which are always in contact
with each other have the same rotary surface speed as the rotary surface speed of
the printing surface of the cylinders.
In some cases where the better printing of engravings is of more importance
than letter press matter, such as in the case of illustrated newspapers, and in such
papers where it would be convenient to print engravings apart from latest news,
I combine with my improved machine a third printing cylinder for printing
engravings which are made ready when for newspapers, long before the letter
press matter containing latest news need be ready, the printing of which in the
most perfect manner is of less importance, so that by my improved machine with
the third printing cylinder will do the work of first class printing for the illustrated
part of the paper, while giving facilities for adding at the last moment and in the
least time the latest information contained in political daily papers. This
improvement is illustrated by Fig. 7 of the drawings.
It will be seen in this figure that the first and second impression cylinders e, and g,
and the small taking off cylinder i, are shown as in Fig. 1, except that the second
impression cylinder g, is lower in position and comes above and between the second
and the third printing cylinders, and 3, which both print upon the same side of the
sheet carried against them by the second impression cylinder g, the sheet coming
first upon the second (4) and then upon the third (3) printing cylinder.
The forms on the second printing cylinder (³) are inked directly by three
inking rollers 21, 22, and 2³, and a series of other rollers marked 1 to 8 inclusive,
the arrangement of which will be understood from the previous description and by
inspecting the figures, the rollers 5, 6 and 8 are or may be end reciprocating
rollers.
The forms upon the third printing cylinder h³, are inked by an arrangement of
rollers same as those for inking the forms on the second printing cylinder h, shown
in Fig. 1, and herein before described.
These arrangements for inking, admit of an inferior ink being used for the first
and second printing cylinders and a better and more expensive quality of .ink
being used for the third printing cylinder ³, for the engravings.
It will be understood that where electros or zincos upon the third cylinder
would print upon the sheet, blanks or unprinting parts are left upon the second
printing cylinder h.
It will also be understood that with my improved machine shown by Figs. 1 and 1ª
modified as illustrated by Fig. 7 printing may be done in colours, in three different
colours if desired, two colours on one side of the sheet, and one on the other side.
