ACTION OF THE APPARATUS.
The sheet of paper is placed on the table U, between the guages which
guide it on the sides and at the front and back, up to the moment when it is
seized by the grippers of shaft C of cylinder F, and pressed on the india-rubber
faced supports D, the cylinder carries round the sheet, which is only held in.
front by the grippers, and at back by a series of metal plates X, which secure
it on the cylinder without the aid of tapes; when the cylinder F has completed
a certain part of its revolution, and the grippers still holding the sheet have
arrived at point R', the grippers C¹ of cylinder G are quickly brought down
so as to grip the sheet while it is also released from grippers C. The cylinder
G carries the sheet round to point. P¹, where the grippers of shaft C¹ open in
order to allow it to pass on the tapes S, S, on which it is conducted to point O¹,
where it falls on to tapes S¹, which convey it to the plates of receiver R, in

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Office on the 18th
December 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of June, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Clark, Her special licence that I, the said William
Clark, my executors, administrators, and assigns, or such others as I, the
said William Clark, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
APPARATUS FOR TYPOGRAPHIC AND LITHOGRAPHIC PRINTING,' a communication to
me from abroad by Auguste Hippolyte Marinoni, and Francois Noel Chaudre,
Builders, both of 29, Boulevart St. Martin, Paris, upon the condition (amongst
others) that I, the said William Clark, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
IN
NOW KNOW YE, that I, the said William Clark, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon, (that is to say):-
Fig. 1 of the annexed Drawing represents a side elevation of the apparatus
complete; Fig. 2, a plan of the base of the apparatus with the sliding carriage
and plate, also showing the method of driving the same; Fig. 3 is an elevation
of the apparatus; Fig. 4, a section on line A, B, C, D, Figs. 2 and 3; while
Fig. 5 represents a longitudinal section of the machine above the framing,
showing the method of seizing the sheet by the grippers of the printing
cylinder, and of the cylinder conducting it on to the tapes; and, lastly, the tapes

page_text: for conveying it on to the mechanical receiver, which deposits it on the
table.
A, Fig. 1, lower framing on which the various parts of the apparatus are
mounted; B, side frames supporting the whole of the driving mechanism;
C, carriage carrying the movable plate, on which is mounted the lithographic
stone or type; D, screws, serving to regulate the height of the plate or movable
plane; E, E, wheels or rollers carrying the carriage C; F, printing cylinder; G,
small. cylinder provided with grippers, serving to take the sheet from the
printing cylinder and to convey it on the tapes; H, curved frame, carrying the
guaging tables, the rollers and tapes, the mechanical receiver, and other parts;
I, receiving table; J, supports of damping rollers; K, supports of inking
rollers; L, supports of distributing rollers; M, rod serving to stop the print-
ing roller; N, principal horizontal connecting rod, having a friction
roller at one end and serving to transmit the motion to the mechanical
receiver; 0, eccentric or cam operating connecting rod N; P, lever having
a toothed segment actuating the shaft of the receiver; R, combination of
wood laths or plates, mounted on an iron shaft, serving to invert the printed
sheet on the receiving table; S, S, tapes for conducting the sheet; T, small
wood table on which the plates R rest in readiness to receive the sheet; A¹,
large toothed wheel, mounted on the shaft carrying the eccentrics for stopping
the cylinder, the eccentric regulating the receiver and the crank which
actuates the plate holding carriage; B', intermediate wheel governing wheel F¹
of the inking cylinder; D', ink reservoir; E', fast and loose punies mounted
on the pinion shaft driving the whole apparatus by any suitable power. This
machine may also be arranged to be driven by hand.
A, Fig. 2, is the lower framing of the machine, showing the ways on which
run the wheels carrying the carriage, the latter being provided with a
plate serving to receive the lithographic stone or type. This plate,
which is commonly termed the slab, is regulated in position in an upward and
downward direction by screws D, Figs. 1 and 3, and sideways by screws Q,
Figs. 2 and 3.
A, Fig. 3, frame of the machine, seen longitudinally; E, E, wheels on
which the carriage Q' is mounted, also showing screws D, and Q, Q, serving
to fix and hold the plate carrying the lithographic stone or type Z, and
section of the metal tube U' for receiving and distributing the ink on the
rollers.
A, Fig. 4, represents a cross section of the frame, showing wheels E of
carriage C, the screws D, D, and Q, Q, holding plate Q2, carrying the stone
or type Z, as before mentioned; F, Fig. 5, is the printing roller; G, cylinder

page_text: of smaller diameter, turning in an opposite direction but at same speed as
cylinder F, and serving to change the direction of the sheet. These two
cylinders are each furnished with two shafts B, B', C, C',. those marked B, B',
having each at the one end a toothed segment, and also furnished with a spiral
spring; the shafts C, C', are also toothed and gear with B, B', being further
furnished with a series of grippers for seizing the paper sheet and pressing
it on the small supports D, D', faced with india rubber, which are mounted
on a rod in the interior of each cylinder. One of these supports in cylinder F
bears fixed points not shown in the Drawing, while on the other end of shafts
C, C, is a small crank furnished with a friction roller, which in
coming in contact with cams mounted on the side frames opens or closes the
grippers when desired; U, guaging table or plate under which is placed the
lever carrying the movable plate, the upper surface of the table being
furnished with guages. The parts for actuating the lever of the movable
pointers, and those for bringing down the grippers of the printing cylinder,
as also other parts not necessary for the elucidation of these improvements,
are omitted in the Drawings, being the same
the same as in ordinary printing
mashinas

page_text: 2ndly, I claim the methods of regulating and fixing slabs of different
thicknesses without the necessity of "overlaying," a perfect regester being
obtained by displacing the slab either laterally or longitudinally without unscrew-
ing as herein-before described.
3rdly, I claim the application to these kinds of printing apparatus of an
intermediate cylinder furnished with grippers for seizing the sheet on the
printing cylinder and conducting it on to the tapes, all as before described and
represented in the Drawings.
4thly. I claim the use and application of the improved mechanical receiver,
as before described.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Eighteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-five.
Witness,
JAMES DAISH,
