Year: 1866

page_text: LETTERS PATENT to Michel Spiquel, of No. 164, Rue St. Honoré, and
Eugène Henry Florange, of No. 106, Rue Vieille du Temple, and of
No. 82, Boulevard Sébastopol, all in Paris, in the Empire of France, Gold
and Silversmiths, for the Invention of "IMPROVEMENTS IN INCURVATING OR
RENDERING CONCAVO-CONVEX METALS EITHER IN A FLATTED OR UNPLATTED
STATE."
PROVISIONAL SPECIFICATION left by the said Michel Spiquel and
Eugène Henry Florange at the Office of the Commissioners of Patents,
with their Petition, on the 23rd April 1866.
We, MICHEL SPIQUEL, of No. 164, Rue St. Honoré, and EUGENE HENRY
FLORANGE, of No. 106, Rue Vieille du Temple, and of No. 82, Boulevard Sébas--
topol, all in Paris, in the Empire of France, Gold and Silversmiths, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN INCURVATING
OR RENDERING CONCAVO-CONVEX METALS EITHER IN A FLATTED OR UNPLATTED
STATE," to be as follows:-
This Invention has for its object the application of hydraulic power in
stamping and moulding metal objects, by which we are enabled to produce
any design whether concave or convex, or a combination of both; with
considerable rapidity and ease. The means we employ are extremely simple,
and compared with those at present in use considerably cheaper in the end;
they consist of an hydraulic press of suitable and convenient size and force
for the work to be executed, set in motion by steam or man power at will;
to the action of this press we submit the moulds or matrices configured

page_text: according to the designed desired to be produced, having the sheet of
metal disposed so as to be conveniently acted on by the piston or stamper.
When the design is of simple form, cylindrical for instance, the plate
of metal to be treated is securely held by key pieces for that purpose, and
gradually acted on by a cylindrical die, which forces the metal through
a succession of metal rings, the last being of the proposed diameter. In
the more complex designs we make use of moulds or matrices in separate
pieces which under the action of the press are gradually forced in situ, so as
to securely surround the metal to be shaped; at this stage water is forced
by the pumps through an opening in the die so as to come in contact with
the upper surface of the metal, and what remains of the configuration to be
completed is thus brought about by the direct action of the water on the
metal, by which it is forced into all the intricacies of the mould however
complicated. When sufficient pressure has been exercised the discharge
cock is opened, and the piston descending frees the mould, on seperating the
parts of which the design is set at liberty:
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Michel Spiquel and Eugène Henry Florange in the Great
Seal Patent Office on the 22nd October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MICHEL
SPIQUEL, of No. 104, Rue St. Honoré, and EUGÈNE HENRY FLORANGE, of
No. 106, Rue Vielle du Temple, and of 82, Boulevard Sébastopol, all in
Paris, in the Empire of France, Gold and Silversmiths, send greeting.
⚫ WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of April, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Michel Spiquel and Eugène Henry Florange, Her special licence
that we, the said Michel Spiquel and Eugène Henry Florange, our executors,
administrators, and assigns, or such others as we, the said Michel Spiquel,
and Eugène Henry Florange, our 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 "In-
PROVEMENTS IN INCURVATING OR RENDERING CONCAVO-CONVEX METALS EITHER

page_text: IN A FLATTED OR UNPLATTED STATES," upon the condition (amongst others) that
we, the said Michel Spiquel and Eugène Henry Florange, our executors or
administrators, by an instrument in writing under our, 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.
NOW KNOW YE, that we, the said Michel Spiquel and Eugène Henry
Florange, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement and accompanying Drawings, that is
to say:-
The present Invention has for its object the application of hydraulic power
in stamping and moulding metal objects, by which we are enabled to produce
any designs, whether concave or convex, or a combination of both, with con-
siderable rapidity and ease. The means we employ are extremely simple, and
compared with those at present in use considerably cheaper; they consist of
an hydraulic press of suitable and convenient size and force for the work to
be executed, set in motion by steam or man power at will; to the action of
this press we submit the moulds or matrices configured according to the
design desired to be produced, having the sheet of metal disposed so as to be
conveniently acted on by the piston or stamper. When the design is of simple
form, cylindrical for instance, the plate of metal to be treated is securely held
by key pieces for that purpose, and gradually acted on by a cylindrical die,
which forces the metal through a succession of metal rings, the last being of the
proposed diameter. In the more complex designs we make use of moulds or
matrices in separate pieces, which under the action of the press are gradually
forced in situ, so as to securely surround the metal to be shaped; at this
stage water is forced by the pumps through an opening in the die, so as to
come in contact with the upper surface of the metal, and what remains of the
configuration to be completed is thus brought about by the direct action of the
water on the metal by which it is forced into all the intricacies of the mould
however complicated. When sufficient pressure has been exercised the dis-
charge cock is opened, and the piston descending frees the mould, on separating
the parts of which the design is set at liberty.

is the cylinder; B, the capital or head of the press; C, C, C, C, the columns;
D, the piston; E, the metal table fixed thereon; F, F, F, F, the cross bar;
G, support for the mould; II, H, H, I, a mould in four parts; I, the cor-

page_text: responding part thereof; J, J, J, J, pins or bolts to check the cross bar in its
descent. Fig. 2, the same press; this Drawing represents it whilst pressure
is being applied to a mould; the same letters indicate like parts in these two
Figures. Fig. 3 is a section of a mould. A is the plate of metal to be treated;
B, the head of the press; F, the cross bar; G, the support to the mould;
H, H, H, the mould in three pieces; i, i, the upper part thereof; K is the
opening to admit the passage of water from the top of the press; L is the
water for forcing the metal into the intricacies of the mould. Fig. 4 is a
design as completed from the mould, Fig. 3. Fig. 5 is a section of another
mould for making taller articles, and is in three pieces A, A, A; B is the
cylindrical piece of metal to be shaped and ready to receive the pressure of
the water L. Fig. 6 is an article completed from the above mould. Fig. 7
is the cross bar with pins supporting a plate. Fig. 8 is the same press shown
in section as arranged for shaping cylindrical articles. A, A, is the cylinder;
B, the capital; C, C, the columns; D, D, the piston; E, E, the plate thereon;
M, the stamping piston connected to the head of the press; N, N, a conical
piece or plate on which are mounted the metal rings a, a, b, b, c, c, d, d,
e, e, f, f, g, 9, h, i, i, j, j, k, k, l, l, m, m, n, n; beneath this latter
is the principal or guage ring, which is of the size of the tube desired to be
produced; beneath this ring the circle P is attached, it is composed of as
many pieces as may be thought desirable, and is kept in its position by the
springs Q, Q, which allow the several parts of which it is composod to open
and close, and thus permit the article to pass when completed; R, R, are a
species of bolts acting on the conical piece N, and arranged so as to move or
slide backwards and forwards as occasion requires; the number of these bolts
may be augmented according to desire or necessity; S, S, are slides, in which
the said bolts move; T, T, U, U, V, V, are rings fitting one over the other,
the first passing round the stamper M; X is a plate or sheet of metal about
to be treated, and is placed on the uppermost rings a, a. It will thus be
seen that on raising the piston D to the stamper M the ring V, V, will be
pressed down as far as the first five rings a, a, b, b, c, c, d, d, e, e, on the
conical piece N; the bolts R, R, at the same time rising on the slides Y, Y,
the pressure being continued the ring U, U, is in a similar manner forced as
far as the next five rings f, f, g, g, h, h, i, i, j, j, and reaching to the next
and last ring T, T; it likewise is driven to the five last set of rings k, k, l, 1,
m, m, n, n, o, o, which latter is of the size of the tube desired to be produced.
In Figure 10 the position of the rings T, T, U, U, V, V, is shown as well
as of the bolts R, R, which it will be seen in sliding up the sides of the
press Y, Y, are gradually forced over the upper part of the said rings and so

page_text: preventing their rising; the pressure is maintained a sufficient length of time
to complete the tube, as shown at Z; the discharge cock is then opened and
the piston descending the tube is forced from it by the ring P, P, in its
passage, the press is then again ready for another operation. Fig. 9 is a
conical piece of metal as it appears before being passed through the guage
ring O. Fig. 10 is a sectional view of the press; the same letters of reference
are employed as in Figure 8, representing the same parts as in that Figure.
Fig. 11 is a tube, as shown at Z, Figure 10, and completed by our process.
Figs. 12, 13, 14, 15, 16 represent this same tube after having been forced
through a different set of rings, each set being gradually smaller; it is with
thes tubes that the several designs, represented by the Figures 17 to 32
inclusive are produced by placing them in moulds, and forcing water through
an aperture therein, so that by its pressure the metal is driven into all the
intricacies of the mould however complicated, as already described.
From the above description, aided by the accompanying Drawings, it will
readily be understood that designs of any conceivable form can easily be
produced, and with a degree of finish and accuracy of detail equal to any
manufactured by any of the processes at present employed, and with the
advantages of economy in labour and expense.
Having thus described our Invention, and the mode of carrying the same
into effect, what we claim and desire to secure by Letters Patent is, the
system of manufacturing various articles in metal of any desired form, and
whether concave or convex, or a combination of both, in the manner and by
the means as herein-before set forth and illustrated by the accompanying
Drawings.
In witness whereof, we, the said Michel Spiquel and Eugène Henry
Florange, have hereunto set our hands and seals, this Thirty-first
day of July, in the year of our Lord One thousand eight hundred
M. SPIQUEL.
