Improvements in Machines for Printing in One or Several Colours on
Flat or Relief Surfaces more especially on Placards, Boards or the
like and particularly on Enamelled Plates.
I, SEVERIN LAZARE DELEUIL, of 124, Rue de France, Vincennes, in the Republic
of France, Constructor, do hereby declare the nature of this invention to be as
follows:
:―
This invention relates to a machine, the object of which is to convey a colour
or an enamel of any desired tint, by pressure, into hollow plates, these hollows
or recesses representing any characters, letters, figures, stereotypes, designs or
the like, which the material, employed, traverses and levels for the purpose of
its being thus applied to the surface to be printed upon.
As has been above stated the object of this machine is to deposit upon pla-
cards, plates and the like a layer of paint, enamel or the like in a given form,
by means of pressure.
For this purpose, we have constructed our machine, by way of example, in the
following manner:
In the upper part of a machine frame, supporting the whole mechanism,
a plate is provided which is fitted with a piston, which latter receives a vertical
alternating movement by a driving crank shaft and by a connecting rod with an
ordinary bearing for the piston and an adjustable eccentric bearing for the
driving shaft. The adjustment of the stroke of the plate, by way of displacing
the eccentric bearing, is obtained by means of a small external hand wheel,
the axis of which terminates in an endless screw, adapted to gear with a worm
wheel, formed by the bearing itself.
The plate is moreover guided laterally in guides provided in the frame. In
the vertical plane of the plate, the machine frame is provided with a seat, upon
which another frame is adapted to rest, which latter receives the plate or the
like, to be printed upon. In the centre of this seat an ejector is arranged,
which is connected to the cylinder with interior piston, by means of a bellows
provided for this purpose.
The piston of the cylinder, which contains the thickly-fluid printing material
is rigidly connected with an endless screw, receiving an ascending or descending
movement by the rotation of a nut, rigid with a worm wheel.
This screw, normally guided by two sockets and two guides fixed to the
cylinder, and the cylinder, which is itself movable, is held in place by means of
a hinged sleeve.
In order to permit of the frames and plates or the like being handled, the
upper part is made movable upon the machine frame. For this purpose the
fixed part of the machine frame has a rack-bar rigidly connected with it, which
rack bar is on its part adapted to gear with a toothed pinion, the axis of which,
being supported in the movable upper part of the machine frame, is provided

page_text: upon its outside with an operating fly wheel, whereby the plate can be com-
pletely displaced.
The operation of the piston for pressing out the material located in the
cylinder, is obtained by means of the driving shaft which is provided at the
side with a grooved cam; this cam actuates an oscillating lever, which trans-
mits its movement to a similar lever by the intermediary of rods acting as
connecting rods.
Upon the free arm of the second lever two pawls are pivotally connected which
are adapted to work on two ratchet wheels.
One of these pawls and ratchet wheels imparts to the piston and consequently
to the printing material the ascending movement by the intermediary of a shaft
and gear wheel, while the other similar couple of working parts communicates
to the piston and to the material the opposite or descending movement.
The stroke of the pawls is limited by two levers held in position at the desired
distance by rack bars.
The two movements of the piston are adjusted in their extent as required,
in order to permit of the changing of the plates, placards or the like, to be
printed upon; for this purpose the actuating fly wheel is mounted loosely upon
the driving shaft; these two parts being rigidly connected by a bolt or pin,
actuated by a leaf- or spiral spring, the effect being to engage the bolt with the
hub of the fly wheel.
The stopping of the plate at the upper end of its stroke is effected by disen-
gaging the bolt from the hub, this disengagement being effected automatically
by the action of a spring and of a bevel edged oscillating lever.
The actuation of the driving shaft by the fly wheel is effected by operating
a pedal, connected to a lever by a rod or connecting rod, which, as it descends,
compresses the spring, causes the lever to oscillate which, in moving away from
the bolt, leaves the latter to the action of the first spring, which drives the same
and engages it with the hub of the fly wheel.
The frame serving to receive the object to be printed upon is fixed in the
centre part of the fixed machine frame and is provided, at will, with any appro-
priate regulating tappets, serving as guides for the object to be printed upon.

Improvements in Machines for Printing in One or Several Colours on
Flat or Relief Surfaces more especially on Placards, Boards or the
like and particularly on Enamelled Plates.
I, SEVERIN LAZARE DELEUIL, of 124, Rue de France, Vincennes, in the Republic
of France, Constructor, 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:-
This invention relates to an improved machine for the printing, either in flat
or in relief, of figures, letters designs or the like on stiff plates of cardboard,
wood, metal, leather and so on.
The impression will be, or not, in relief according as to whether the printing
material is employed in form of ink, or enamel of more or less consistency
or viscousness.

page_text: a stencil plate beyond which it slightly extends and is thus applied to the surface
for printing.
The invention is illustrated in the accompanying drawings, in which:
Figure 1 is a front elevation of the machine, its upper portion being shown
in section.
Figure 2 is a central vertical section.
Figure 3 is a section on the line x-x of Figure 1.
Figure 4 is an elevation (looking from the left of Figure 1) showing the
mechanism for driving the forcing piston.
Figure 5 is a plan of part of the said driving mechanism.
Figure 6 is a plan of the frame serving to receive the plates to be printed upon,
and
Figure 7 is a plan of a stencil-plate adapted to be placed on the distributing
plate.
Figure 8 is a view showing in elevation and plan a stencil plate for use in
printing in more than one colour.
The machine is constructed as follows:
In the portion A' of the frame A supporting the entire mechanism, a plate B
is mounted and fitted with a piston B₁ which has imparted to it a vertical
reciprocating motion by means of a pulley T keyed to a horizontally disposed
crank shaft J which acts in conjunction with a connecting rod or link 1), the
latter being connected to the piston by an ordinary bearing and to the shaft J
by an adjustable eccentric bearing C.
The vertical stroke of the platen B may be adjusted by displacing the eccen-
tric bearing C by the aid of a small hand wheel O provided with an endless
screw 01 which gears with a worm wheel C formed on the bearing.
The platen B is guided laterally in guide grooves provided in the frame A.
Vertically below the travelling platen B in the frame A is provided a seat
or bed a upon which is adapted to rest 1stly. the distributing plate e Figure 6
with the substance to make the impression, and
2ndly, a frame gresting upon elastic supports g¹ and upon which is disposed
the plate or material to be printed upon 2 before the platen B starts moving
downward in order to bring the blank into contact with the printing substance.
Upon the distributing plate e is fitted into grooves el a cut stencil plate e
from which the printing substance issues through the holes, representing letters,
numbers, and other signs, just far enough to be even with the outer surface,
without however allowing the printing substance to spread beyond.
To the centre of and below the distributing plate e is fitted a tubular
socket E having a flange E¹ to which is secured by means of a flange E
and screws an elastic joint or bellows F which, when the printing substance
used is viscous or of rather great consistency, becomes slightly dilated by taking
in some of the substance forced back through the pressure exerted by the
platen B, thus obviating the danger of spreading the substance over the stencil
plate and of producing blurred outlines on the printed material.
The lower edge of the bellows F is secured between a loose flange F1 and the
flange of a pump barrel I, the flanges being rigidly connected together by
screws . The piston I¹ of the pump barrel I is formed integral with an endless
screw and has imparted to it an ascending or descending motion through
the intervention of a screw nut V integral with a worm wheel U.
The screw X is guided vertically by two guiding sockets and guide bars c
fixed to the cylinder or pump barrel I.
The pump
barrel I is firmly secured to the frame A by means of a collar Iª
one half of which latter is cast in one with the frame while the other half is
hinged to its counterpart by a pin I³ and locked by a screw I'.

page_text: In order to permit of the stencil plate e being changed and also of removing
the printed plates 92 the upper portion A' of the frame is made removable and
can be moved laterally away from the stencil plate 2.
To this end the stationary portion A of the frame is formed with a rack H
in which gears a pinion h the spindle of which is carried in a bracket A2 and is
fitted with a hand wheel G by means of which latter the said pinion may be
rotated upon the stationary rack and so move the platen B.
The operation of the piston for expressing the printing substance contained
in the pump barrel I is effected through the intervention of the shaft J which
for this purpose is fitted at one end with a grooved cam P (Figures 1 and 4).
This cam operates a bell crank lever P¹ which transmits its movement on to
a similar lever Q through the intervention of rods q by which they are con-
nected together.
To the free arm of this lever Q are hinged two pawls R R¹ engaging two
ratchet wheels S S¹ Figures 1 and 5. One of these pawls and ratchet wheels
imparts, through the intervention of the shaft U₁ and worm-wheel U, an ascend-
ing motion to the piston I¹ and consequently also to the printing substance,
while the other similar couple causes their inverse movement.
The stroke of the pawls R R is limited by two levers 3, held in the required
position by means of rack bars x x¹.
The shaft J is driven by any suitable motor with transmissions as may be
required applied to the pulley T which latter is mounted loose on the shaft J
but which may be fixed thereon by the following means:
The hub of this pulley is formed with a recess k adapted to receive a bolt K
which slides in a ring fast on the shaft J. This bolt is constantly impelled
towards and into the hub of the pulley through the action of a spring i. The
engagement of the bolt K with the pulley is effected through the intervention
of a foot lever N connected to a stop lever L by means of a spring controlled
rod m, having springs n n¹; the arrangement being that the depression of the
foot lever causes the stop lever L to be disengaged from the bolt K. so allowing
the latter under the impulse of its spring i to penetrate the recess of the
pulley T.
The disengagement between the shaft J and pulley T is effected by
releasing the foot lever N by which then the rod m under the tension of the
springs operates the lever L and causes this latter to engage with its incline
between the inclined head of the bolt K and the hub of the pulley which then
revolves free upon the shaft.
The working of the apparatus is as follows:
The pump barrel I or cylinder having been charged with printing substance
the stencil plate e and the plate to be printed upon are arranged in their
proper place. By now engaging together the shaft J and pulley T the printing
substance is gradually but very slowly forced to the level with the stencil plate e
whereupon the platen B descends immediately and presses the plate g², for print-
ing, together with its frame g by compressing the springs thereof, against the
stencil plate e² and so into contact with the printing substance level with the
stencil plate.
At the moment when the plate is imprinted the shaft J and its connected parts
including the cam P have only performed half a revolution, and, during the next
half revolution the platen B is caused to ascend, while the piston I descends.
If at the completion of the revolution the foot lever is set free the springs n n¹
nctuate the lever L to disengage the bolt K from the pulley thus stopping the
mechanism and enabling the plate, and, if desired also the stencil plate, to be
changed.
To enable this to be effected by means of the hand wheel G, pinion h and
rack H, the portion A¹ of the frame is moved rearward, and, after then having
changed the plate as required, the portion A¹ is replaced and thereupon the
foot lever N is moved to engage the pulley and the operation is repeated.
When it is desired to print simultaneously in two or more colours I furnish

page_text: my machine with the required number of additional cylinders similar to that
shown in the drawings. Each such cylinder containing a different colour and
leading, by its upper end into one of the compartments formed in the distribut-
ing plate e by means of vertical partitions upon which is placed the stencil.
These partitions may be fixed either to the plate e or to the stencil as may be
most convenient.
In order that the above may be better understood I have shown in Figure 8
a cut-stencil plate both in elevation and in plan, and bearing the word "Paris,"
the letter P of which it is desired to print in a different colour to that of the
other letters.
To this end I have fixed beneath the stencil a partition a a adapted to reach
down to the bottom of the distributing plate e and thus divide the same into
two separate compartments. Each compartment is in communication with one
of the cylinders shown by dotted lines in Figure 8.
The principle herein described with reference to two colours may evidently be
applied for printing with any desired number of colours, without departing
from the spirit of the invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. In printing machines, the combination with a stationary frame A having
fixed to it at the centre a pump barrel or cylinder I held in a hinged collar I2
and serving to contain the ink, paint or enamel for printing, the said pump
barrel or cylinder being surmounted by a bellows F and a distributing plate c
which carries a stencil e suitably cut, of a frame g provided with compressible
supports and serving to receive the plate to be printed upon.
2. The combination with a pump barrel or cylinder with distributing plate,
stencil and frame for the reception of the plate to be printed upon, of a piston I¹
for expressing the printing material, and having a reciprocating motion im-
parted to it by means of ratchet wheels operated by pawls actuated through
the intervention of a grooved cam P on the pulley shaft.
3. The combination with a pump barrel or cylinder and piston as herein before
claimed, of a cranked driving shaft provided with an adjustable eccentric bear-
ing C and operating a movable platen B so as to press upon the plate to be
printed upon.
4. The combination of a stationary frame A with movable upper portion A¹
adapted to make a rearward motion upon the stationary frame through the inter-
vention of a hand wheel with pinion and stationary rack for the purpose of
facilitating the changing of the plates to be printed upon, and also the stencils.
