Patent Offices, 24, Rue du Mont Thabor, Paris, in the Empire of
France, and 38, Porchester Terrace, Bayswater, in the County of
Middlesex, Patent Agent, for the Invention of "AN IMPROVED LITHO-
CHROMOLITHO TYPOGRAPHIC PRESS."-A communication from Jean Baptiste
Huguet, residing at Paris, Rue St. Maur.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 29th June 1864, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 24, Rue du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED LITHO-
CHROMOLITHO TYPOGRAPHIC PRESS," communicated to me by Jean Baptiste.
Huguet, a person residing at Paris, Rue St. Maur, and have petitioned Her
Majesty to grant unto me, my executors, administrators, and assigns, Her
Royal Letters Patent for the same, and have made solemn declaration that it
is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand and seal,

page_text: fully describes and ascertains the nature of the Invention, and the manner in
which the same is to be performed, that is to say:-
These improvements consist in a peculiar arrangement of the machine
which allows of printing in lithography and chromolithography (the principal
object of my Invention,) and also in typography or letter press by means of a
table of suitable thickness, adjusted on the marble bed, on which table the
forms are placed. This table is removed and the stones placed on the marble
bed when the press is to be used for lithographic printing. These improve-
ments also consist in a peculiar arrangement of the means of working the
clasps on the cylinder and the points by means of several movements, which
will be hereafter described, and in the arrangement of an adjustable pressure
on the stone for producing the impressions.
In the annexed Drawings, Fig. 1 is a side elevation of the improved press,
and Fig. 2, a section in elevation of the same seen from the opposite side.
In both Figures the same letters of reference indicate similar parts:
All the movements and mechanism of the press are mounted on the
úprights A joined by strong tie beams B, carrying the ways C and the small
bowls D held between two iron bands E and rolling on the ways C which
carry the chariot F. The chariot F is moved by means of the connecting
rod H, one end of which is fixed to the toothed wheel G, gearing with the
pinion I, mounted on the main shaft J. The shaft J carries the fixed and
free pullies K, K, and the fly wheel L. The connecting rod H is forked at
the other end, and receives a pin N, which is guided by the slides M ; on
this pin rolls a toothed wheel O, the lower part of which gears with a rack P
fixed to the centre tie-beams, and the upper with a rack Q fixed under the
chariot F. The toothed wheel C is mounted on a shaft R, on which are fixed
two excentrics S, S, which work a connecting rod T fixed at the other end to
a fork U, which starts and holds the cylinder in place. When the chariot E
is at the end of its course, a rack V fixed to it gears with the toothed wheel
of the cylinder X, and turns the latter during the whole of its return course.
The clasp Y fixed to the cylinder is opened when its bowl Z meets the
lever a, which is worked from below by a rod 6 moved by the chariot F by
means of a pin; a spiral spring c rolled round the rod b brings it back to its
place.
The cylinder X is supported on an axle which passes quite through it; the
axle is upheld by the brasses e, e, in two parts. On the upper parts of these
brasses repose the covers f, f, constantly drawn downwards by the drawing"
rods 9, 9, and the levers h, h, with the weight i, which make the pressure
necessary for printing during the passage of the stone. The paper is placed

page_text: on a table supported by the arched rods b. The sheets are marged on the
table m by means of small moveable angle blocks. The layer having pre-
sented the sheet to be printed to the clasp Y on the cylinder, the said clasp is
immediately shut by the spring n, and a peculiar piece o, mounted on the
axle p, presses on a sector q, so that small arms are raised under the tails of
the clasps, and force them to remain shut during the printing.
The cylinder X is covered with an envelope of cloth or felt, which may be
strained at will by means of a small ratchet wheel t fixed on a square rod in
a hollow place reserved for the purpose in the cylinder. In order that the
sheet may be better guided on the cylinder, it is pressed by several arched
rods placed near the cylinder; these rods may be replaced by a cloth
tightened on the cylinder, or by several strings or tapes. The inking roller u
is acted upon by several angular pinions moved by the shaft R. The feeding
ink roller is worked by an excentric mounted on the axle of the inking roller.
The distributing rollers turn on the bearers v, which are sufficiently numbrous
to allow of inclining or slanting the rollers at will. The inking rollers x,
which come in contact with the form or the stone, turn on bearers y fixed on
the frame A. The openings of the bearers allow of slanting the rollers in
order to ink from corner to corner as when inking by hand. The same
remark applies to typographic or letter-press printing. The waterers are
placed in front of the cylinder X, and wet the stone both in going and
coming.
Having thus described the nature of the said Invention, and the manner in
which the same is to be performed, I would have it understood that I do not
confine myself to any particular form, dimensions, or means of working said
machines; but what I claim is the general arrangement of the various organs
composing the above "Improved Litho-chromolitho Typographic Press," and
particularly the adjustable or moveable pressure by means of articulated
drawing rods g, g, a part of which is hidden by the framing, and the means of
operating the clasps and points.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Twenty-eighth day of June, in the year of
our Lord One thousand eight hundred and sixty-four.
H. BONNEVILLE. (L.S.)
