Mennons and De Telescheff, Home and Foreign Patent Agents, 24,
Rue de Dunkerque, Paris, in the Empire of France, for the Invention
of "IMPROVEMENTS IN MACHINERY FOR PUNCHING AND CUTTING METALS."—
A communication from Nicolas de Telescheff, (Captain of Artillery,)
residing at No. 16, Malaya Morsquaïa, St. Petersburgh, in the Empire
of Russia.
PROVISIONAL SPECIFICATION left by the said Marc Antoine François
Mennons at the Office of the Commissioners of Patents, with his Petition,
on the 24th January 1863.
I, MARC ANTOINE FRANÇOIS MENNONS, of the Firm of Mennons and De
Telescheff, Home and Foreign Patent Agents, 24, Rue de Dunkerque,
Paris, in the Empire of France, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR PUNCHING AND CUTTING
METALS," (a communication) to be as follows:-
This Invention consists in an improved combination of mechanism, applied
to the construction of punching and cutting machinery, as shewn by the annexed
Drawing, in which Figure 1 is a vertical section of the apparatus, and Figure 2
a front view of the same.

page_text: A is a cast-iron frame carrying at its upper part a the shears b, b¹, and at its
lower part a' the punch c and bed plate c'. The lower shear blade b¹, and the
punch c, are mounted on vertical slide bars d and e, operated by the horizontal
levers f, f, one of which is shewn apart in Fig. 3. 9, g', are pivots or trun-
nions fixed to the slide bars d, e, and bearing on the fore ends of the levers
ff; h is a moveable axle, placed between the levers, and serving as point of
rotation to the coupling hooks n, n, by which these levers are connected with
the slide bars. In the tapped bearings k, k', adjusted to the hind extremities
of the levers, passes a screw i, ¹, threaded to the right over one half of its
length, and to the left in the other half, and provided at the top with a hand
bar or wheel of any suitable form. o, p, q, o' p', q'. are gorges formed in the
plates m, m³, the slide bars d, e, and the frame a, a', to receive the conical
keys 1, 1, by which one of the two slide bars is kept stationary, while the
other is at work.
To cut the metal with the machine constructed as above, the keys 1, l, are
nserted as seen in Fig. 1, in the lower gorges o¹, p¹, q', thus securing in posi-
tion the punching apparatus. The screw i,, is then turned from left to
right, and by its action on the cylindrical bearings k, k³, causes the hind extre-
mities of the levers f, f, to separate, while the front ends close on each other,
in turning on the axle h. The traction exerted in this movement on the pivot g
carries down the slide bar d, thus allowing the metal to be passed between
the shears. The screw is then reversed, the hind extremities of the levers
reclose, the fore ends reopen, and by their pressure on the pivot g force upwards
on the metal the slide bar with its blade.
For punching, the keys 1, 1, withdrawn from the gorges o¹, p', q¹, to free the
slide bar e are set in o, p, q, and the shearing apparatus being thus secured in
its turn, the levers f, f', are alternately opened and closed, under the action of
the screw, in the manner above described.
Figure 4 represents in vertical section the frame of a portable apparatus for
punching only; Figure 5 is a front view of the same.
In this arrangement the shearing mechanism is entirely suppressed and
replaced by a fixed cross bar, on which is mounted the trunnion 9. The other
parts of the machine are in all points similar to those above described and shewn
in the preceding Figures.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Marc Antoine François Mennons in the Great Seal Patent
Office on the 10th July 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the Firm of Mennons and De Telescheff,
Home and Foreign Patent Agents, 24, Rue de Dunkerque, Paris, in the
Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of January, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Marc Antoine François Mennons, Her special licence that I, tho
said Marc Antoine François Mennons, my executors, administrators, and
assigns, or such others as I, the said Marc Antoine François Mennons, 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 IN MACHINERY FOR
PUNCHING AND COTTING METALS," (a communication from Nicolas de Telescheff
(Captain of Artillery,) a person resident at No. 16, Malaya Morsquaïa, St.
Petersburg, in the Empire of Russia, upon the condition (amongst others)
that I, the said Marc Antoine François Mennons, my executors or adminis-
trators, 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.
NOW KNOW YE, that I, the said Marc Antoine François Mennons, do
hereby declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Figures of the accompanying
Drawing, and to the letters marked thereon, that is to say :-
This Invention consists in an improved combination of mechanism, applied to
the construction of punching and cutting machinery, as shewn by the annexed
Drawing, in which Figure 1 is a vertical section of the apparatus, and Figure 2
is a front view of the same.

page_text: A is a cast-iron frame carrying at its upper part a the shears b, 61, and at its
lower part a¹ the punch c and bed plate c¹. The lower shear blade b' and
the punch care mounted on vertical slide bars d and e, operated by the hori-
zontal levers f,f, one of which is shewn apart in Fig. 3. 9, 9', are pivots or
trunnions fixed to the slide bars d, e, and bearing on the fore ends of the levers
ff; h is a moveable axle placed between the levers, and serving as point of
rotation to the coupling hooks n, n, by which these levers are connected with
the slide bars. In the tapped bearings k, k', adjusted to the hind extremities
of the levers, passes a screw i, i, threaded to the right, over one half of its
length, and to the left on the other half, and provided at the top with a hand-
bar or wheel of any suitable form. o, p, q, o¹, p', q', are gorges formed in the
plates m, m³, the slide bars d, e, and the frame a, a', to receive the conical
keys 1, 1, by which one of the two slide bars is kept stationary while the other
is at work.
To cut the metal with the machine constructed as above, the keys 1, 1, are
inserted, as seen in Fig. 1, in the lower gorges o¹, p', q', thus securing in posi-
tion the punching apparatus. The screw i, i, is then turned from left to right,
and by its action on the cylindrical bearings k, k³, causes the hind extremities
of the levers f. f, to separate, while the front ends close on each other in
turning on the axle h. The traction exerted in this movement on the pivot g,
carries down the slide bar d, thus allowing the metal to be passed between the
shears. The screw is then reversed, the hind extremities of the levers reclose,
the fore ends reopen, and by their pressure on the pivot 9 force upwards on
the metal the slide bar with its blade.
For punching the keys 1, l, withdrawn from the gorges o¹, p, q, to free the
slide bar e, are set in o, p, q, and the shearing apparatus being thus secured in
its turn, the levers f, f', are alternately opened and closed under the action of
the screw in the manner above described.
Figure 4 represents in vertical section the frame of a portable apparatus for
punching only; Figure 5 is a front view of the same.
In this arrangement the shearing mechanism is entirely suppressed and
replaced by a fixed cross bar, on which is mounted the trunnion g. The other
parts of the machine are in all points similar to those above described and
shewn in the preceding Figures.
Having now described the nature of the said improvements, and the manner
of carrying them into effect, I would have it understood that I do not confine
myself to the precise details of construction above laid down, as these may be
modified without deviating from the principles or characteristic features of the

page_text: Invention; but what I claim and desire to secure by Letters Patent, is, the appli-
cation to the construction of punching and cutting machinery of the levers f. ƒª,
in combination with the slide bars d, e, and the screw i, i, the whole arranged
and operated in connexion with the auxiliary mechanism, in manner, substan-
tially as herein set forth, and shewn in the Figures of the annexed Drawing.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereto set my hand and seal, this Fourth day of July, in the year of
our Lord One thousand eight hundred and sixty-three.
M. F. MENNONS. (L.S.)
