page_text: LETTERS PATENT to Henri Adrien Bonneville, of the British and
Foreign Patent Offices, 18, Rue de la Chaussée d'Antin, Paris,
France, and 6, Piccadilly, in the County of Middlesex, Patent
Agent, for the Invention of "A NEW AND IMPROVED PRINTING PRESS."
-A communication from Stanislas Alexandre Louis Berthier,
residing at Rue de Rivoli, 152, Paris, France, Merchant.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 1st January 1874, 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, 18, Rue
de la Chaussée d'Antin, Paris, France, and 6, Piccadilly, in the County
of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "A NEW AND
IMPROVED PRINTING PRESS," communicated to me by Stanislas Alexandre

page_text: Louis Berthier, a person resident at Rue de Rivoli, 152, Paris, France,
Merchant, and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for
the same, and made solemn Declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby 5
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the Invention, and
the manner in which the same is to be performed, reference being had
to the accompanying Drawings, and to the figures and letters marked
thereon, in which Fig. 1 represents a vertical front view of the printing 1
press; Fig. 2, a vertical longitudinal side view of the same; Fig. 3, a
a plan top view of the same; and Fig. 4, a vertical longitudinal side view
showing the upper parts of the press opened and unoperating. In these
Figures the same letters indicate similar parts.
This printing press consists of three main parts, the frames supporting 1
the setting of types together, the upper frame and the compressing
parts being one with the latter.
A represents the framework, the upper part of which B is hollowed to
receive the moveable bed plate C. The latter is supported by four screws.
the square heads of which are kept in square notches in the bottom 2
part of bed plate C, in order to prevent the unscrewing of screws during
the work.
The moveable frame F is laterally maintained in position on the bed
plate C by means of ribs E on the framework A. The composition G
is placed in the inner of the frame F and upon the bed plate C, and it is 2
fixed in the frame by the means now in use.
The back part of the frame H is connected with the framework by
two hinges I, and maintained in position on the framework by means of
two hooks L connected in front of the frame by a cross shaft K, the
ends of which are provided with two handles.
The hooks L are constantly kept in the notches L in the framework A
by means of two flat springs in the lower part of the said hooks.
O is a moveable platten provided at its lower part with a tympan P.
This platten is maintained in position by means of four spiral springs Q
surrounding the spindles R, the lower part of which is screwed in the 3

page_text: frame H. This platten O may be raised according to the more or less
pressure to which it is submitted. Its upper part is also provided with
two friction rollers S moveable on their pivots.
T is a shaft on which are keyed, 1st., an eccentric U; 2d., another
eccentric carrying at its upper part a lever arm V, the pins of which
turn in the bearings X, which may be moved up and down, and vice
versa, and are inserted in the inner part of the uprights Y on the frame H.
The upper parts of the bearings X are maintained by means of two
small pins a operated by screws Z, the ends of which are cut with
circular grooves for this purpose. These screws are screwed in the
uprights Y, which allows to raise or lower as required the bearings X,
the shaft T, and at the same time the eccentrics U and the lever V.
6 is a came keyed on the elongated axle journal of the shaft T, which
regulates the pressure by striking against the screw head c, screwed in
the rib d of the frame H.
Mode of Operating.-Fig. 4 clearly represents two different parts :—
1, the framework A of the printing press; 2, the frame H supporting
the compressing parts opened in the vertical position by means of pins J.
The composition or form G is placed and kept in position by usual
means between the frame F, stopped laterally by ribs E upon the bed
plate C and the framework A. The ink is put as usually, and the sheet
of paper to be printed is placed, the two handles K are seized and the
frame H lowered. The handles are quickly let off, and immediately by
means of springs M the hooks L are inserted in the notches N, and the
framework A and the frame H are thus connected together. Then a
vertical motion is imparted to the lever V, which makes a quarter of
revolution. This motion is transferred through the shaft T on which
the lever is keyed to the eccentric V, acting on the friction rollers S
fixed on the platten O, which is depressed according to the pressure
given by the lever V, an press the sheet of paper upon the form G.
To bring back the platten as before, the lever is operated in opposite
directions, the platten is immediately raised under the action of spiral
springs Q. The hooks L are then disengaged from the notches N, and
the compressing upper parts retake their first position.
The printing press above described may be constructed of the smallest
size and conveyed from place to place, and laid upon either a table, or a
counter, or a shelf, or any other suitable support.

page_text: Having thus described the nature of the said Invention, and the
manner of carrying it into effect, I would have it understood that I do
not confine myself to the precise details above enumerated, as these
may obviously be modified without departing from the principle of the
Invention, but what I claim is, in constructing moveable printing press,
the arrangement and combination with the frame H and the platten O
of the compressing part, the latter being a lever or a screw, or other
suitable mechanical contrivance, provided that the upper part of the.
press are connected together and operating substantially as above.
described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have
.hereto set my hand and seal, this Twenty-ninth day of December,
in the year of our Lord Eighteen hundred and seventy-three.
