I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said Inven-
tion for IMPROVEMENTS IN MACHINES OR APPARATUS FOR PRINTING FROM
ENGRAVED PLATES, BLOCKS, LITHOGRAPHIC STONES, OR FROM OTHER LIKE PRINTING
SURFACES," to be as follows:-
This Invention relates to apparatus for printing all kinds of designs, writing
or marks, engraved or otherwise, on paper either in the length or in sheets, on
fabrics, or other material capable of receiving an impression.
This apparatus is represented in the accompanying Drawings together with
the parts for producing the different movements of the plates of the p
fabrics and scrapers.

on a fixed shaft s.. When the stud k comes in contact with the projection l
the pulley p is caused to turn in the direction of the arrow as shown, and
imparts to the carriers c, c', a rectilinear motion drawing them one towards the
other. For this purpose the carriers are provided with friction rollers t, t,
running cn rails fixed on the inside of the framing u, u', studs mounted on
the faces of the toothed wheels j,j, during the rotary motion of which wheels
these friction surfaces come successively in contact with the projections v, v¹,
fixed on the rods a, y, which by being moved to the right or left raise or
lower the scrapers by the aid of rods y; 1, 11, Fig. 7, cleaners, consisting
of metal plates which are in contact with the scrapers throughout their

matters which might injure the plates; these cleaners are operated by the
same parts u, u', which are employed for raising or lowering the scrapers.

this bar is provided with tappets 3, 31, actuated by the studs u, u, for pro-

and bevil pinions 7, 8, Figure 5; 9, 91, pulleys mounted on each end of
shaft 4; 10,10,pulleys mounted on the bearings of the scrapers; 11,11, cords,
the two ends of which are fixed to the cleaning plate and passing over
pullies 9, 10. The cleaning plate 1, Figure 7, is guided transversely on rods
12, 13, fixed to the part carrying the scraper, so that when the shaft 4 turns
the cleaner bears on the whole width of the scraper as before mentioned;
when the two carriers advance towards each other and have arrived at the
end of their traverse it is necessary that a certain time should elapse before
they separate, for this purpose I apply a spring catch 14 on the carrier C,
taking into a part 15 on the carrier C¹, as seen in Figure 3, a pin 16 mounted
on the side of the toothed wheel, also produces at a given time the oscillation
of a double-armed lever 17 for raising spring 14, and so liberating the two
carriers when they are required to separate.
Having thus described the mode of producing the movements of the plates,
scrapers, and cleaners, I will proceed to explain the action of the apparatus.
The two plates are shown in the act of pressing with the scrapers E, E¹,
raised to permit of the plates passing in the direction of the arrows.
The
pressing action is obtained by the projecting parts 18, 19, of the cylinders B, 1}',
which raise the plate carriers and effect contact of the plates with the paper
fabric, and with the pressing rollers A, A¹. The carriers are provided with
projections 32, Figures 3 and 4, which abut against the projections 33,
Figure 6, on the ends of the pressing rollers, and serve to start the latter.
The plates are thus moved by the combined pressure of the cylinders A, A¹,
B, B1, and when the parts 18, 19, of the cylinders B, B¹, cease to act on
the carriers the pressure also ceases and the latter will be gently lowered, their
rectilinear movement being continued by the teeth 20, 20, mounted laterally
on cylinders B, B', and acting on teeth 21, 21, formed on the carriers until
the latter have passed entirely under the inking rollers, fƒƒ³; at this
movement the cylinders A, A', B, B', have sufficient space between them to
permit of the plates passing without contact with the paper or fabric being
printed. The scrapers E, E', are then lowered, and the plates being brought
back by the stud / which turns the shaft n, as before mentioned, by the aid

page_text: of the bands q, 2, on pulley p, the scrapers are so caused to remove any
superfluous ink or color, leaving only that which is in the engraved surface,
and on the plates returning to their first starting point the scrapers rise, the
cleaners are brought into action, and the parts 18, 19, of the cylinders B, 31,
again raise the carriers, which are then carried along by pressure as before, in
order to produce a fresh printing action. The paper which is first wound upon
a reel passes under the roller A' where it receives a first impression, thence over
rollers c,c,c,and underthe second roller A, where it receives a fresh impression
on the opposite side. The paper fabric or other surface to be printed is
wound off by the pressure as the impression proceeds, but as the plate might
be of greater length than the engraved part too much paper would be wound
off, and it would be necessary to wind on again in order to match the designs;
for this purpose I dispose two cross pieces 22, 22, at the ends of the pressing
rollers A, A, and on the further side of the machine, which cross pieces are
caused to abut against two projections 23, 23, fixed on the toothed wheels 24,
25, which receive motion from wheels 26, 27, keyed on the ends of the
cylinders B, B, by this means the cylinders A, A', may be partially rotated
in a reverse direction to the winding off motion for the purpose of making the
engraved designs or patterns match one with the other. During the return
motion of the carriers two projecting parts 28, 281, remove the ink with
which the scrapers are covered before the cleaners come into action, this ink
falls into the cavities 29, 29', and from there runs through the flexible pipes
30, 301, into the vats 31, 311.
The Invention thus consists of improved apparatus for printing all kinds
of designs or writing engraved or otherwise on paper, either in continuous
iengths or in sheets, or it may be on any kind of fabric capable of receiving
an impression, it being understood that the mode of transmitting motion to
the various parts may be varied without departing from the principle of the
Invention. The apparatus may also print on one side only of the paper or
fabric, and several colors may be employed in the same machine.

:-
This Invention relates to apparatus for printing all kinds of designs, writing,
or marks, engraved or otherwise, on paper either in the length or in sheets,
or on fabrics, or other material capable of receiving an impression. This
apparatus is represented in the accompanying Drawings, together with the
parts for producing the different movements of the plates, of the paper, or

page_text: 9, 10. The cleaning plate 1, Figure 7, is guided transversely on rods 12,
13, fixed to the part carrying the scraper, so that when the shaft 4 turns,
the cleaner bears on the whole width of the scraper as before mentioned.
When the two carriers advance towards each other and have arrived at
the end of their traverse it is necessary that a certain time should elapse
before they separate; for this purpose I employ a spring catch 14 on the
carriage C, taking on to a part 15 on the carrier C', as seen in Figure 3; a
pin 16 mounted on the side of the toothed wheel ; also produces at a given
time the oscillation of a double armed lever 17, for raising spring 14, and
so liberating the two carriages when they are required to separate.
Having thus described the mode of producing the movements of the plates,
scrapers, and cleaners, I will proceed to explain the action of the apparatus.
The two plates are shown in the act of pressing with the scrapers E, E¹,
raised to permit of the plates passing in the direction of the arrows. The
pressing action is obtained by the projecting parts 18, 19, of the cylinders B, B¹,
which raise the plate carriers, and effect contact of the plates with the paper
fabric and with the pressing rollers A, A'. The carriers are provided with
projections 32, Figures 3 and 4, which abut against the projections 31,
Figure 6, on the ends of the pressing rollers, and serve to start the latter. The
plates are thus moved by the combined pressure of the cylinders A, A, B, B',
and when the parts 18, 19, of the cylinders B, B', cease to act on the carriers
the pressure also ceases, and the latter will be gently lowered, their rectilinear
movement being continued by the teeth 20, 20, mounted laterally on cylin-
ders B, B', and acting on teeth 21, 21, formed on the carriers until the latter
have have passed entirely under the inking rollers f. f', f, f3; at this moment
the cylinders A,A', B, B', have sufficient space between them to permit of the
plates passing without contact with the paper or fabric being printed. The
scrapers E, E, are then lowered, and the plates being brought back by the
stud, which turns the shaftn, as before mentioned, by the aid of the bandsq, q',
on pulley 2, the scrapers are so caused to remove any superfluous ink or color,
leaving only that which is in the engraved surface, and on the plates returning
to their first starting point the scraper rises, the cleaners are brought into
action, and the parts 18, 19, of the cylinders B, B', again raise the carriers,
which are then carried along by pressure, as before, in order to produce a
fresh priuting action. The paper, which is first wound on a reel, passes under
the roller A', where it receives a first impression, thence over rollers c, c, c,
and under the second roller A', where it receives a fresh impression on the
opposite side. The paper fabric or other surface to be printed is wound off
by the pressure as the impression proceeds, but as the plate might be of greater

page_text: length than its engraved part too much paper would be wound off,. and it
would be necessary to wind on again in order to match the designs; for this
purpose I dispose two cross pieces 2, 2, 2, 2, at the ends of the pressing
rollers A, A', and on the further side of the machine, which cross pieces are
caused to abut against two projections 23, 23, fixed on the toothed wheels 24, 25,
which receive motion from wheels 26, 27, keyed on the ends of the cylinders
B, B; by this means the cylinders A, A', may be partially rotated in a
reverse direction to the winding-off motion for the purpose of making the
engraved design or patterns match one with the other. During the return
motion of the carriers two projecting parts 28, 281, remove the ink with which
the scrapers are covered before the cleaners come into action; this ink falls
into the cavities 29, 291, and from there runs through the flexible pipes 30, 30',
into the vats 31, 31'.
Having described the nature of this Invention, and this Invention, and the
manner of performing the same, I declare that what I claim as the Invention
to be protected by the herein-before in part recited Letters Patent is, the
improved apparatus herein described and represented in the annexed Drawings
forprinting all kinds of designs or writing engravedorotherwise on paper, either
in continuous lengths or in sheets; or it may be on any kind of fabric capable
of receiving an impression, it being understood that the mode of transmitting
motion to the various parts may be varied without departing from the principle
of the Invention. I also reserve the right of printing on one side only of
the paper or fabric in the manner described, and also of printing in several
colors in the same machine.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Twenty-fifth day of September, in the year of our
Lord One thousand eight hundred and sixty-seven.
