Office of the Commissioners of Patents on the 22nd September 1881,
HENRY HARRIS LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN CHROMATIC PRINTING
MACHINERY." [A communication from abroad by Joseph Augustin Heuse,
Engineer, and Georges Jouanny, both of Paris, France.]
This Invention relates to cylindrical.chromatic printing machines, and its object
is to provide an improved machine for the printing of wall paper or bangings or
other work, that is to say, printing in various colours upon a continuous strip or
web of paper.
In the said machine the cylinder having the devices for ensuring the proper
registering of the colours is an indispensable auxiliary for effecting this object
during the first passage of the sheet through the machine, also for the subsequent
impressions of other colours, and thus the printing is effected with exactitude and
regularity.
In carrying the said Invention into practice I provide a recl upon which the
sheet or web to be printed is wound; as it unwinds from this reel the paper passes
to the said cylinder, upon which there are devices for securing the registering of
the separate colours; it goes thence to a small roller, from which it passes
tangentially to a blanket cylinder which is in direct frictional connection with two
cylinders, upon which are the plates containing the design or pattern or a portion
thereof to be impressed. The paper receives one colour from the first of these
cylinders, and another colour from the second, then it is released and goes to a
drying apparatus of ordinary construction, and is dried in the air.
The chief novel feature in my improved machine consists in the devices or
arrangement whereby I am enabled to effect the perfect registering of the colours
in the second or subsequent impressions, that is to say, when the paper passes

page_text: through the machine subsequently to the first passage, this being effected by regu-
lating the two aforesaid cylinders carrying the pattern or designs according to or
in conjunction with the colour registering devices on the first named or registering
cylinder. For this purpose I provide on the first pattern or design cylinder a
driving wheel which is loose on its spindle, there being another wheel which is
fixed. On the second pattern cylinder there is a circular plate or disc which
is keyed on its spindle, and there is also à wheel which is loose. By means
of these parts the position of the devices on these cylinders for ensuring the proper
registering of the colours may be regulated by screws so as to perfectly coincide
with those on the first named or registering cylinder. The loose wheel on the
first pattern or design cylinder, also the disc on the second pattern or design
cylinder, are pressed into contact with the two other wheels; this operation is
effected every time that a slight displacement takes place in the paper, which
would affect the accuracy in the registering of the second or subsequent impression
when the paper has been rewound upon the reel after being dried.
In this machine the pattern or design cylinders reproduce a continuous design
which may or may not be repeated upon their circumference.
For the printing of colours the distribution thereof. inust be effected with con-
siderable power and regularity of touch, without which spots or lumps caused by
the sudden impact of the colours upon the pattern or design cylinders would cause
an unequal spreading thereof upon the pattern or design to be reproduced. The
devices I employ for the distribution of the colours are as follow, that is to say:—
Each pattern or design cylinder has in connection therewith a separate colour
reservoir in which a roller revolves. For the first pattern cylinder the colour
taken up by the revolving roller is conveyed to another roller in contact therewith,
which deposits it upon a cylinder. For the second pattern or design cylinder the
colour is taken from the roller revolving therein and conveyed to a cylinder, but
by means of an additional roller. In connection with each of the said cylinders
there are three distributing rollers which move in a contrary direction to the
cylinders.
The colour is conveyed to the pattern cylinders from the cylinders upon which
it is deposited, as above set forth, by means of seven rollers on each side, four of
these rollers on each side being in contact with one of the said pattern cylinders.
Two of the rollers in contact with those next, the pattern cylinders have a motion
in a contrary direction to that of the rollers which they touch so as to distribute
the colour regularly or evenly on the latter.
The blanket cylinder which receives the pressure of the pattern..or design
cylinders is provided with an endless blanket which passes around a roller and is
thus stretched.
. For large establishments two or more of these machines may be employed and
placed in connection with each other, being caused to work together at exactly
the same speed. By this arrangement I obtain successively and at one passage
of the sheet a greater number of colours printed side by side, or over or upon each
other. This arrangement has also the advantage of economising time considerably
with respect to drying, and the changing of colour distributing rollers and patterns
or designs. The machines are coupled or joined as follows, that is to say, upon
the driving shaft of one machine I provide a bevel toothed wheel, which by means
of a horizontal shaft and another toothed wheel sets in motion the driving shaft of
the next machine. Upon the driving shaft of the first machine I provido a fly
wheel and a pulley, the latter receiving the strap or band which imparts the
necessary motion. The paper as it comes from the first machine is placed by
means of its first register mark upon the corresponding device on the registering
cylinder of the second machine, and passes thence to the pattern cylinder of this
machine to receive other colours, these cylinders having been previously regulated,
as described; with respect to the first machine.

passes
In carrying the said Invention into practice I provide a reel A upon which the
sheet or web to be printed is wound; as it unwinds from this reel the paper passes
to the cylinder B', upon which are arranged devices for securing the registering of
the separate colors; it goes thence to the small roller C, from which
tangentially to the blanket cylinder D, which is in direct frictional contact with
the two cylinders E¹, E², upon which are the plates containing the design or
pattern, or a portion thereof, to be impressed. The paper receives one color from
the cylinder E¹ and a second color from the cylinder E; it is then released, and
goes to a drying apparatus of ordinary construction and is dried in the air.
The chief novel feature of my improved machine consists in the devices or
arrangement whereby I am enabled to effect the perfect registering of the colors in
the first and subsequent impressions (that is to say, when the paper passes through.
the machine subsequently to the first passage), this being effected by regulating
the two cylinders E¹, E³, carrying the pattern or design according to or in con-
junction with the color registering devices on the registering cylinder B¹. For
this purpose I provide on the cylinder E¹ the driving wheel a (Figures 2, 4, and 5)
which is loose on its spindle, and another wheel b which is fixed. On the
cylinder E is a circular plate or disc a' (Figure 6) which is keyed on the said
spindle, and a whcol b' which is loose. The wheels a and b and the wheels a¹
and b' are respectively connected to one another by lugs x (Figures 4 and 7). By
ineaus of these parts the position of the devices on the said cylinders for ensuring
the proper registering of the colors may be regulated by the adjusting screws v, v..
so as to perfectly coincide with those on the cylinder B'. The wheel a and the
circular plate or disc a³ are respectively pressed into contact with and secured to.

page_text: the wheels b, b¹, by means of the adjusting screws v, v, and the bolts y (Figures 8
and 9) passing through elongated holes in the arms of the wheels to facilitate the
adjustment of the color registering devices. This operation is effected every timo
that a slight displacement takes place in the paper, which would affect the accuracy
in the registering of the second or subsequent impression when the paper has been
rewound upon the reel after being dried.
In this machine the pattern or design cylinders reproduce a continuous design
which may or may not be repented upon their circumference.
For the printing of colors the distribution thereof must be effected with con-
siderable power and regularity of touch, without which spots or lumps caused by
the sudden impact of the color upon the pattern or design cylinders would cause
an unequal spreading thereof upon the pattern or design to be reproduced. The
devices I employ for the distribution of the colors are as follows, that is to say,
each pattern or design cylinder has in connection therewith a separate color
reservoir F, F', in which a roller G revolves. For the first pattern or design
cylinder the color taken up by the revolving roller G is conveyed to another
roller H in contact therewith, which deposits it upon the cylinder I. For the
second pattern or design cylinder the color is taken by the roller H' from the
roller G revolving therein, and conveyed by means of the roller M₁ to the
cylinder I. In connection with each of the said cylinders are arranged three
distributing rollers J, J, J, which move in a contrary direction to the cylinders
with which they are in contact. The two rollers K, K¹, and the cylinders 1, I',
transmit the color by contact with the feeding rollers L, L, L, to the four rollers
M, M, M, M, in contact with the cylinders E¹; E. The feeding rollers L, L, L,
have a motion in a contrary direction to that of the rollers which they touch so as
to distribute the color regularly or evenly on the latter.
The blanket-cylinder D which receives the pressure of the pattern or design
cylinders is provided with an endless blanket which passes around a roller d, and
is thus stretched.
For large establishments two or more of these machines may be employed and
placed in connection with each other, being caused to work together at exactly the
same speed. By this arrangement I obtain successively and at one passage of the
sheet or web a greater number of colors printed side by side or over or upon each
other. This arrangement has also the advantage of economizing time considerably
with respect to drying, and the changing of color-distributing rollers and patterns a
or designs. The machines are coupled or joined as follows, that is to say, upon
the driving shaft N of one machine is fixed a bevel toothed-wheel O, which by
means of the horizontal shaft P and the toothed wheels O, O', transmits motion
to the driving shaft N' of the next machine. Upon the driving shaft N of the
first machine are placed the fly-wheel Qand the pulley R, the latter receiving the
strap or band which imparts the necessary motion. The paper as it comes from
the first machine is placed by means of its first register mark upon the corre-
sponding device on the registering cylinder B2 of the second machine, and passes
thence to the pattern cylinders E³, E, of this machine to receive other colors, these
cylinders having been previously regulated, as described, with respect to the first
machine.
Having thus fully described the said Invention, as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it under-
stood that I do not restrict myself to the general arrangement shown, which may
be modified as desired, but I claim,―—
First. A machine for printing in colors provided with a cylinder or cylinders
having devices for ensuring the proper registering of the colours during the first
and subsequent passages of the sheet or web through the machino, by which devices
great exactitude and regularity of the impressions may be obtained, substantially
as specified.
Second. A cylinder provided with devices for ensuring the proper registering of
the colors, substantially as specified.
