Year: 1854

page_text: LETTERS PATENT to Antoine Edouard Brisbart Gobert, of Montmirail
(Marne), in the Empire of France, for the Invention of "A NEW KIND
OF STAMPING PRESS."
Sealed the 3rd April 1855, and dated the 13th November 1854.
PROVISIONAL SPECIFICATION left by the said Antoine Edouard Brisbart
Gobert at the Office of the Commissioners of Patents, with his Petition,
on the 13th November 1854.
I, ANTOINE EDOUARD BRISBART GOBERT, of Montmirail, Département de la
Marne, in the Empire of France, do hereby declare the nature of the said
Invention for "A NEW KIND OF STAMPING PRESS" to be as follows:-
'A new press for printing with ink of any colour, but in such a way that
'the operation of inking and taking the impression is performed by the press
itself.
Fig. i is a perspective view of the press; Fig. 2 and 3 are elevations and
plans of the lever by which it is worked. These two latter Figures are on an

page_text: entering a slot cut through G, which it raises or lowers; o, o, pivots, which
rest on the arm of the frame M; and round which pivots the lever L moves;
1,1, two rods, hanging on pivots e, e, while from the end of the lower arm K of
the lever L, to which rods the inking roller is fixed, so that it may revolve
freely, in order that it may become charged with ink as it runs in the inking
table, supplied by the ink reservoir.
On depressing lever L towards the left, the slide G is of course lifted up,
and the stamping piece T along with it. This stamping piece terminates by a
cross piece t, provided on each side with a small lever a, united by hinges with
the connecting-rods A, A.-R, helical spring connecting the rods A together.
When G is raised, so that the levers a, a, are brought to a horizontal
position, the end i of the driving lever gets out of the slot; the slide G and
stamping piece remain motionless whilst the roller r moves forward to ink the
stamping piece. If the lever L be then moved towards the right, the slide G
descends, and the end is getting again out of the slot; the spring R pulls
abruptly the rods A, A, back, and as they are connected with the slide G by
means of the rods a, a, the stamping piece Tris by their motion depressed, so
as to give an impression to the article which may be placed on the receiving
table P.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Antoine Edouard Brisbart Gobert in the Great Seal Patent
Office on the 11th May 1855.***
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANTOINE
EDOUARD BRISBART. GOBERT, of Montmirail (Département de la Marne), in
the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her-Letters
Patent, bearing date the Thirteenth day of November, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Antoine Edouard Brisbart Gobert, Her special license that I, the
said Antoine Edouard Brisbart Gobert, my executors, administrators, and
assigns, or such others as I, the said Antoine Edouard Brisbart Gobert, 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

page_text: the United Kingdom of Great Britain and Ireland, the Channel Islands; and
Isle of Man, an Invention for "A NEW KIND OF STAMPING PRESS," upon the
condition (amongst others) that I, the said Antoine Edouard Brisbart Gobert,
by an instrument in writing under my hand and seal, 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.
NOW KNOW YE, that I, the said Antoine Edouard Brisbart Gobert,
do hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My
new press for printing with ink of any color performs the double opera-
tion of inking and stamping by the reciprocating motion of a lever. Two
varieties of the said press are represented in the annexed Drawings, in which
the same letters indicate the same parts.
Figure 1, elevation and perspective view of a press, in which the stamp T'is
inked by means of the roller r, which receives its charge of ink from an inking
table, on which it is made to roll up and down by means of the lever L, which
is set in motion by working the handle N:
Figure 2, side elevation; Figure 3, end elevation on the opposite side of the
stamp; Figure 4, plan of a similar press, in which the stamp T is inked by
the action of the lever L, which presses it upon a cushion F, Figures 2 and 4,
saturated with ink, and stretched over an inking case E, Figures 5 and 6.*
The press consists of a cast-iron block B, supported on two feet p, p, at the
back; an iron plate D is screwed under the block at y, and is provided with a
third foot p; so that the apparatus may stand firm. P is a receiving table,
covered up with a soft material, and placed on the plate D directly under the
stamp. The material to be stamped is placed on this table P, two uprights M
fixed to the block B, and serving as guides to the slider H, which is provided
with a projecting foot c, furnished with a socket h, to which the stamp may be
fixed by means of a thumb screw f. Figures 7 and 8 are separate front and
side views of the slider II with its appurtenances. On either side of the lower
part of this slider there are two lugs o, o, where two small rods a, a, are
hinged. The other end of these rods is jointed to the lower extremity of the
two levers A, which hang from and pivot on the pins d, fixed at the top of the
uprights M. A helical spring R connects the jointing pins of the rods a and
levers A, drawing them nearer each other, whilst the slider H, as it ascends
along M, compels them to diverge or recede from each other, because the lugs

page_text: 0,0, carrying up the lower joints of the rods a, whilst the upper joints of the
same rods are kept down by the rigid levers A, are thereby prevented from
ascending, so that these levers are thus compelled to diverge, and the spring R
is stretched accordingly. When the slider H has attained its highest pitch,
the rods a, a, are nearly in a horizontal position, and the stamp remains
motionless; it is while in that position that it is inked, either by the roller 1,
as already mentioned, Figure 1, or by means of the inking cushion represented
in Figures 2, 3, 4, namely, by means of the lever L, which causes the stamp
to touch the inking cushion F of the inking case,, represented separately in
Figures 5 and 6. When the stamp has been inked, the sheet to be stamped
is placed on the receiving table P; a motion is then imparted to the lever L,
which enters into a slot of the slider E, and causes this piece to slide down,
carrying along with it the joints of the rods a, a. As soon as the latter have
reached a point a little below the horizontal position, they no longer can main-
tain on the stretch the spring R, which, being thus at once relaxed, draws
together the levers A, in consequence of which, the rods a, taking immediately
also an almost vertical position, carry the slider I down, and the stamp T
falling suddenly down, an impression is produced on the material submitted to
its action.
In the arrangement represented in Figure 1 the motion is imparted to the
lever L by the handle N; the arm K of that lever draws the inking roller over
.the inclined cover of the ink case E, whilst the other arm causes the slider H
to come down. In the arrangement represented in Figures 2, 3, 4, the handle
N is not wanted, the lever L is inverted, its fulcrum remains always between
the brackets O of the uprights M.
The arm of the lever opposite to K being useless is dispensed with, and the
arm K, which is inserted into the slot of the slider F, drives it up and down
in the same manner. Motion is imparted to the lever L by applying the hand
to the extremity of the arm K. The table P is not fastened to the plate D;
it is merely supported at the centre, as seen in Figures 3, 4, 7, so as-to-be-
enabled to incline-to a certain extent on either side, so as always to coincide
with the surface of the stamp, which for the same reason is loosely fixed in a
socket h, placed in the foot C, so that the stamp may adjust itself to the incli-
nation of the table P.. In the press, Figure 1, the ink is placed in a wedge-
shaped reservoir E, whence it oozes out through a narrow slit upon the inking
table, which can completely slide in, so as to close entirely the slit, and thus
shelter the ink, when the press is not used, from being spoiled by dust or other
impurities. I can entirely dispense with the inking table, and instead of it use
, a cushion, made of a suitable cloth, stretched on a small frame, which may be

page_text: placed on the block B. This cloth, being imbued with ink, forms an elastic
inking table for the roller. The ink holder of the press, represented in Figures
2, 3, 4, consists in a small box made of metallic sheets. Figure 5 is a side
elevation, and Figure 6 is a plan thereof. It is composed of a closed reser-
voir E, within which the semi-fluid ink is put. The upper side of this reservoir
is perforated with several small holes, and a cloth is tightly stretched over it
without touching it, by means of two small iron rods-n, n. In order to charge
the reservoir with ink, this cloth may be removed, and the ink case, being
withdrawn from the block, is turned upside down, so that, the ink oozing
through the small holes, the stretched cloth becomes thus imbued with ink,
and will remain moist with it for a long time. The ink holder is pushed
with the hand on the block B, so as to bring the cushion directly under the
stamp, or to remove it from under it; and it is provided at the back b' with a
slot v, where there is a screw fixed to the block B, so that it can be removed
only when it is entirely drawn back; when not in use it is covered up with
a little tin cover C¹ above the cloth, so as to shelter it from dust.
In witness whereof, I, the said Antoine Edouard Brisbart Gobert, have
hereunto set my hand and seal, this Ninth day of May, in the year of
our Lord One thousand eight hundred and fifty-five.
