page_text: I, CHARLES JULES DERRIEY of 1 Boulevard St Denis, Paris, France, Mechanical
Engineer do hereby declare the nature of this invention to be as follows:-
Hitherto rotary printing machines have been constructed with the object of
producing entire sheets, half sheets or quarter sheets, each of these fractions
constituting a unit of the journal or print, the maximum being obtained by the
entire development of the printing cylinders.
Journals and newspapers are now published which comprise besides the journal
proper one or more supplements equivalent to an amount of print sometimes equal
to and even greater than the journal itself. To produce these journals with their
supplements it has been usual to use one machine to print the journal itself while
by another machine or by previous printing on the same machine the supplement
or supplements have been printed and it has been necessary to afterwards insert
the supplements by hand into the journals and this involves considerable work.
•
Now the object of the present invention is to do away with this hand work by
printing the journal and the supplement simultaneously and delivering the two
together by a single operation.
This might be effected very simply so far as mechanical construction is concerned
by making a machine with cylinders large enough to receive the "forms" of both
the journal and the supplement; these cylinders would be quite filled when the
journal and supplement were of the maximum amount and only proportionately
filled when the journal was to have either no supplement or a small supplement.
A machine of variable size would deliver sheets of a dimension proportionate to
the surface to be printed and the object would thus be attained in the most simple
manner. But the productive power of the machine as regards the number of copies
would be limited and for this reason I have designed an arrangement in which are
combined two rotary machines the one of which prints the journal proper and the
other the supplement.
The first machine prints either entire sheets (generally equivalent to 8 news-
paper pages) or half sheets (4 pages). It may either be a machine of fixed size,
that is to say, cutting its paper after printing, or one of variable size. The second
machine prints at will either entire sheets, half sheets or quarter sheets and is
specially intended for producing the supplements. The arrangements are such that
the sheets printed by the second machine are placed directly into those printed by
the first machine. There is an accumulator to superpose several sheets from both
when necessary and when the desired number of sheets is attained they are
directed to receiving apparatus such as those now in use, that is to say, to receiving
apparatus for unfolded journals, or to a folding apparatus when folding is required.
The paper for the journal proper unwinds from a reel or drum and is drawn
between the first type cylinder and an impression cylinder and is printed on
the first side, and then between the second type cylinder and another impression

page_text: cylinder and is printed on the other side. It then passes between two cutting
cylinders. One of these cylinders, say the upper, is equal to half the printing
cylinders and the lower is equal to two thirds of the upper. It follows that the
knife or cutter for dividing the sheets meets the lower cutting cylinder at two
points of the circumference of the latter diametrically opposite and thus at each
turn of the upper cylinder a portion of paper equal to half the circumference of the
printing cylinders is detached, and if it was necessary for this portion of the sheet
to be of double length, that is to say, equal to the whole circumference of the
printing cylinders it would suffice to form in the lower cutting cylinder a recess to
prevent the knife of the upper cylinder meeting the paper that passes round the
lower cylinder. The sheets thus detached continue their course and reach another
pair of cylinders.
At the same time as the operations above described are being effected another
roll of paper on a reel at the other end of the machine unwinds and is drawn
between similar type and impression cylinders and printed upon both sides and
then passes on to the pair of cylinders which the sheets from the first portion of
the machine were last described as reaching, the two portions of the machine being
so worked that the beginning of a sheet from the first roll coincides with the
beginning of a sheet from the second roll. This pair of cylinders cuts the sheets
from the second roll like the previous pair of cylinders cut the sheets from the first
roll. The sheets from the two rolls are thus superposed and they leave the
cylinders in a double thickness of paper. From there the sheets, each equal to a
half circumference of the printing cylinders, are conducted to an accumulator. The
first sheets make the circuit of the accumulator and return to the starting point
thereof just as the second sheets from the second cutting cylinders reach the same
point. The result is that inasmuch as at first two sheets were superposed between
the second cutting cylinders and two other similar sheets were afterwards super-
posed, if the two first have made a circuit which brings them back to the point of
departure of this circuit at the precise moment when the second sheets arrive there,
the superposition of these four sheets is effected, and there is thus formed a journal
of 16 pages composed of four sheets of four pages each.
Each of these copies is passed on to the receiving or folding apparatus.
When instead of producing journals of 16 pages it is necessary to produce
journals of 12 pages, I proceed as follows:-The first roll of paper is unwound,
printed and cut as before; the paper from the second roll on the contrary is passed
between a pair of cylinders having a circumferential speed equal to half the rest of
the machine; it is then passed between a pair of cylinders which cut the quantity
of paper supplied by the said slower cylinders, that is to say, a sheet equal to half
the circumference of the printing cylinders. This half sheet is passed between the
two type cylinders and their impression cylinders and then to the cylinders where
it meets the sheets from the first roller as before (but the cutter of these cylinders
is previously removed); the machine is worked so that the beginning of this half
sheet meets the beginning of the first half sheet from the first roll. These two
half sheets being superposed pass on to and make the circuit of the accumulator
and meet the second half sheet from the first roll. Thus three 4-page sheets are
superposed forming a journal of 12 pages which is passed on to the receiving or
folding machine.
When it is wished to produce journals of only six pages or to insert a supple-
ment of two pages into a number of eight pages, it suffices to place in the second
portion of the machine a roll of paper of only half the width and to have "forms"
for only half the width of this portion of the machine.

page_text: I CHARLES JULES DEBRIEY, of 1 Boulevard St Denis, Paris, France, Mechanical
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 :-
Hitherto rotary printing machines have been constructed with the object of
producing entire sheets, half sheets or quarter sheets, each of these fractions con-
stituting a unit of the journal or print, the maximum being obtained by the entire
development of the printing cylinders.
Journals and newspapers are now published which comprise besides the journal
proper one or more supplements equivalent to an amount of print sometimes equal
to and even greater than the journal itself. To produce these journals with their
supplements it has been usual to use one machine to print the journal itself while
by another machine or by previous printing on the same machine the supplement
or supplements have been printed and it has been necessary to afterwards insert
the supplements by band into the journals and this involves considerable work.
Now the object of the present invention is to do away with this hand work by
printing the journal and the supplement simultaneously and delivering the two
together by a single operation.
This might be effected very simply so far as mechanical construction is concerned
by making a machine with cylinders large enough to receive the "forms" of both
the journal and the supplement; these cylinders would be quite filled when the
journal and supplement were of the maximum amount and only proportionately
filled when the journal was to have either no supplement or a small supplement.
A machine of variable size would deliver sheets of a dimension proportionate to the
surface to be printed and the object would thus be attained in the most simple
manner. But the productive power of the machine as regards the number of copies
would be limited and for this reason I have designed an arrangement in which
are combined two rotary machines the one of which prints the journal proper and
the other the supplement
The first machine prints either entire sheets (generally equivalent to 8 news-
paper pages) or half sheets (4 pages). It may either be a machine of fixed size,
that is to say cutting its paper after printing, or one of variable size. The second
machine prints at will either entire sheets, half sheets or quarter sheets and is
specially intended for producing the supplements. The arrangements are such that
the sheets printed by the second machine are placed directly into those printed by
the first machine. There is an accumulator to superpose several sheets from both
when necessary, and when the desired number of sheets is attained they are
directed to receiving apparatus such as those now in use, that is to say to'
receiving apparatus for unfolded journals or to a folding apparatus when folding
is required.
.

page_text: A machine constructed according to my invention (with the exception of the
receiving apparatus) is shown in longitudinal elevation in the annexed drawings.
The right hand portion is shown in Sheet 1 and the left hand portion in Sheet 2.
The paper for the journal proper unwinds from a reel or drum R and is drawn
between the first type cylinder A and an impression cylinder B and is thus printed
on the first side; then between the second type cylinder D and another impression
cylinder C and is thus printed on the other side. It then passes between two
cutting cylinders E F. The cylinder E is equal to half the printing cylinders and
the cylinder F is equal to two-thirds of the cylinder E. It follows that the knife
or cutter for dividing the sheets meets the cylinder F at two points of the circum-
ference of the latter diametrically opposite and thus at each turn of the cylinder E
a portion of paper equal to half the circumference of the printing cylinders is
detached, and if it was necessary for this portion of the sheet to be of double
length, that is to say equal to the whole circumference of the printing cylinders it
would suffice to form in the cylinder F a recess to prevent the knife of the cylinder E
meeting the paper that passes round the cylinder F. The sheets thus detached
continue their course and reach the cylinders Ę F.
At the same time as the operations above described are being effected another
roll of paper on a reel R¹ at the other end of the machine (see Sheet 2) unwinds
and is drawn between similar type and impression cylinders A¹ B¹ C'D' and is
thereby printed upon both sides and then passes on to the pair of cylinders E¹ F,
the two portions of the machine being so worked that the beginning of a sheet
from the first roll coincides with the beginning of a sheet from the second roll.
The cylinders E¹ F¹ cut the sheets from the second roll like the cylinders E F cut
the sheets from the first roll. The sheets from the two rolls are thus superposed
and they leave the cylinders E¹ F¹ in a double thickness of paper. From there
the sheets, each equal to a half circumference of the printing cylinders, are
conducted to an accumulator G G¹. The first sheets make the circuit of the
accumulator and return to the starting point thereof just as the second sheets from
the cylinders E¹ F1 reach the same point. The result is that inasmuch as at first
two sheets were superposed between the cylinders E F and two other similar
sheets were afterwards superposed, if the two first have made a circuit which
brings them back to the point of departure of this circuit at the precise moment
when the second sheets arrive there, the superposition of these four sheets is
effected, and there is thus formed a journal of 16 pages composed of four sheets of
four pages each.
Each of these copies is passed on to the receiving or folding apparatus by means
of the rollers H H¹.
When instead of producing journals of 16 pages it is necessary to produce
journals of 12 pages I proceed as follows:-The first roll of paper is unwound,
printed and cut as before; the paper from the second roll on the contrary is passed
between a pair of cylinders I, J having a circumferential speed equal to half the
rest of the machine; it is then passed between a pair of cylinders E F which cut
off the quantity of paper supplied by the cylinders I, J, that is to say a sheet
équal to half the circumference of the printing cylinders. This half sheet is passed
between the two type cylinders A¹ D¹ and their respective impression cylinders
B¹ C¹ and then to the cylinders E¹ F¹ where it meets the sheets from the first roll
as before (but the cutter of the cylinder E¹ is previously removed); the machine is
worked so that the beginning of this half sheet meets the beginning of the first
half sheet from the first roll. These two half sheets being superposed pass on to
and make the circuit of the accumulator G G¹ and meet the second half sheet froin
the first roll. Thus three 4-page sheets are superposed forming a journal of
12 pages which is passed on to the receiving or folding machine.
When it is wished to produce journals of only ten pages or to insert a
supplement of two pages into a number of eight pages, it suffices to place in the
second portion of the machine a roll of paper of only half the width and to have
"forms" for only half the width of this portion of the machine,

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
The combination in one machine of two distinct rotary printing machines the
one of which will print two half sheets (an entire sheet) for every revolution of
the printing cylinders and the other will print either two half sheets (an entire
sheet) or one half sheet or one quarter sheet each of these portions being then
superposed with the two half sheets from the first machine and the superposed
sheets being then carried on to an accumulator, all substantially as set forth.
