I AUGUSTE SALJN of 84 Avenue Philippe Auguste Paris France Mechanical
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in stamping machines such as are used in
the manufacture of bolts, rivets, and various kinds of ironwork, and in stamping,
drawing, cutting chasing, agglomeration &c. the object of such improvements being
to obviate fracture of the framework of the machine, also to steady the upper part of
the central or working screw in those stamping machines in which the stroke or
movement of the tool holder is comparatively long, and also to provide an automatic
arrangement for removing the object which has been stamped.
In order to carry out this invention stamping machines are constructed in which the
frame work is formed of two parts, (an upper part, and a lower part) of cast iron firmly
united by steel columns which are let into the upper and lower parts of the framework and
secured thereto by means of screw plugs. These columns also serve as guides upon which
guide pieces work, these are shaped so as to have the form of the columns and are
fixed to the toolholder which is thereby guided in its vertical movements. In the
upper part of the machine an arch piece is provided carrying a socket which serves at
the same time as a guide for an elongation of the central or working screw and for
a frame which is used to connect two parts of the driving axle in a manner to be
hereinafter described. The arrangement for automatically removing the stamped
articles comprises a counterbalanced lever or levers actuated by tappets and
connected by means of connecting rods with claws or jaws the arrangement being
such that the said claws or jaws are caused to grip and ungrip the pieces stampel.
I will for the sake of illustration describe my improvements applied to a machine
arranged to stamp the heads of cartridges of large calibre to which is adapted my
improved system for automatically extracting the cartridge.
Instead of constructing the framework of the machine in a single piece of cast
iron as it has been ordinarily made, I make it in two pieces of cast iron, the one
a lower one and the other an upper one. These two parts are separated by two steel

page_text: columns. These columns are fitted by means of prolongations of smaller diameter into
the lower cast iron part and the columns themselves support all the upper cast iron
part. They are fixed to these cast iron parts by steel taper screw plugs having a very
slight cone and which bind the whole together in such a manner as to offer no play,
and so that it shall be as rigid as a framework made all in one piece.
The columns serve at the same time to guide the tool holder which is fixed in four
guide plates taking exactly the form of the columns. The tool holder is put in
movement by a screw surmounted by a fly wheel to which a movement of rotation is
communicated in the ordinary manner, in one direction or the other, according as
it is in contact with one or the other of two discs, both turning in the same direction,
but which are placed opposite to the ends of a diameter of the fly-wheel. When the
stroke of the tool holder is relatively great, there results an increase of force, and in
consequence their is a tendency to bend the screw. To remedy this inconvenience, I
surmount the upper part of the framework by an arched piece carrying a guide in
which a prolongation of the screw passes, thus steadying it at its upper end.
To suit this construction, the driving shaft is formed in two independent parts,
each one furnished with a pulley. These two shafts carry each of them a driving
disc, which acts, when required, by friction upon the periphery of the fly wheel-
when one disc is caused to act on the fly wheel it is turned in one direction, and
when the other disc is caused to act upon it, the fly wheel is turned in the opposite
direction.
In order to obtain a simultaneous displacement of the two dises (in a lateral sense,
or in the sense of their axes), the two shafts are connected by a frame, and motion is
communicated to them by a system of levers.
The working of the plunger, of the false plunger, and of the pincers, is effected
in the ordinary manner. The extraction of the stamped piece is effected automatically
by means of an extractor which comprises ordinarily two claws or jaws connected
together, and also connected to the tool holder, by means of four connecting rods,
suitably articulated to them. At the upper extremity of one of these connecting rods
I fix a little lever, furnished with a counter-balance weight. When the tool holder
arrives at the bottom of its stroke, one of the extremities of this lever takes against a
little tappet, the lever is thereby oscillated, and opens the claws or jaws; as soon as
the tool holder commences to ascend a plunger worked automatically (but which may
be worked by hand) raises the carta idge and the counter-balance weight of the above
mentioned lever acting at the same time on the lever draws together the claws or
jaws which then seize the head of the cartridge. At the upper part of the stroke of
the tool holder, the other extremity of the lever strikes against a suitably placed screw
tappet which tips up the lever, oscillates the connecting rod, and thus opens the claws
or jaws so as to leave the cartridge free. The two claws or jaws can be united
together and worked conjointly by the action of a single lever, or they may have
each one its separate lever and tappets.

page_text: I, AUGUSTE SAIJN of 84 Avenue Philippe Auguste, Paris, France, Mechanical
Engineer, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to improvements in stamping machines such as are employed
in the manufacture of bolts, rivets and various pieces of ironwork, and in stamping
drawing, cutting, chasing, agglomeration etc., the object of such improvements being
to impart greater solidity to the framing whilst blows are being given; to afford more
exactness in guiding the working screw and to provide means for removing the pieces
stamped in an automatic manner.
Figs. 1 and 2 of the annexed drawings are respectively an elevation and a horizontal
section of a stamping machine embodying my improvements such machine being
suitable for stamping the heads of cartridges of large size, or metallic cases for
cartridges used in quick firing guns.
Fig. 3 is an elevation of the means employed for automatically extracting or'
removing the stamped articles.
Fig. 4 (sheet 2) is a vertical section of a machine designed particularly to stamp
small articles of ironwork, bolts, rivets, nuts &c.
Instead of constructing the frame work of the machine in a single piece of cast iron
as has usually been done heretofore, I make it in two pieces of cast iron, one lower
one A and an upper one B. These two parts are separated by two steel columns C. C.
These columns are fitted by means of prolongations or extensions of less diameter into
the lower part A and support the whole upper portion B. They are fixed to these
castings by means of strong steel pins c. c. c. which have a very slight conicity so as
to secure the parts in such manner as to be as rigid as a framework made in a single
piece.
The columns also serve as guides for the tool holder, which is fixed in four
bars a, a, which conform exactly to the shape of the columns.
The tool holder is operated by the screw D which is surmounted by a flywheel E. to
which rotary movement is transmitted in the ordinary manner in one direction or the
other according as it is in contact with one or the other of the discs F or G both of
which rotate in the same direction.
When the stroke of the tool holder is relatively great there results an increase of
force from the increased diameter of the driving discs, and there is consequently a
tendency to bend the screw D.
To remedy this inconvenience the upper portion B is surmounted by an arched
piece H carrying a guide piece M in which an extension d of the screw D
passes.
To suit this construction the driving shaft is composed of two independent shafts each
provided with a pulley.
In order to ensure the simultaneous displacement of the two discs in the direction of

page_text: their axis, the two shafts are connected by an iron frame N and motion is communicated
to them by means of the levers L. L.
The removal or extraction of the stamped pieces (cartridge heads or similar articles)
is effected automatically.
This removal is commenced by the stem or plunger which in its ascent detaches
the article by raising it to the desired height, and the extraction is completed by the
device shown in Fig. 3 as hereinafter described. The tool holder C¹ is connected by
two rods T, T, one passing from each side of the frame to a cross piece P which is
provided with a conicle hole whose smallest diameter is equal to the diameter of the
sleeve R. The false plunger h¹ carries at its lower end two spring-actuated tongs or
jaws h which grasp the cross piece P. When the tool-holder ascends, it carries with
it the cross piece P and consequently also the false plunger ', and the plunger h which
latter raises and detaches the stamped article which is partially engaged in the lower
die or matrix.
When the tongs have reached a certain height they engage in the lower or
recessed end of the sleeve R, close and are released or escape from the cross piece P
which continues its ascending movement following that of the tool-holder C. It is at
this moment that the cartridge case or other article is seized by the extractor, shown
in Fig. 3. This apparatus comprises two claws or jaws g. y. suitably connected
together and to the tool holder by means of four small connecting rods b, b, b, b, jointed
at their upper ends. At the extremity of one of these rods is fixed a small counter-
weighted lever l. When the tool-holder C reaches the lower end of its stroke, one of
the ends of the lever bears upon a small stop t; the lever is thereby oscillated and
causes the claws g to open or move apart. When the tool holder has reascended 'to_a
certain height, that is to say, at the moment the tongs "escape from the cross piece P,
the counterweight of the lever 1, acting upon this lever, causes the claws or jaws g. g.
to approach each other, and grasp the head of the cartridge.
At the upper end of the stroke of the tool-holder (the other end of the lever /
strikes against a screwed tappet t¹ which tips up said lever oscillates the connecting
rod and effects the drawing apart or opening of the jaws so as to leave the cartridge
free. During this time the plunger and the false plunger fall down by their own
weight upon a wooden stop, and, when the tool redescends, the tongs h" give way and
again grasp the cross piece P. The two claws or jaws may be connected together and
work as one by the action of a single lever l, or each may have a distinct lever and its
stops or tappets t t. The stroke of the plunger h is regulated by means of the double
nuts on the rods or stems T. T.
In stamping ordinary small articles of ironwork the machine shown in Fig. 4 can
advantageously be employed. In this machine a plunger his employed, operated by
a foot lever S pivotted at S¹ and one end of which takes against a projection S' on the
movable support m. This plunger / works at its upper end in a case or guide d fitted
in the framing of the machine, above which is the block or matrix m, that receives the
article to be stamped or forged. The lower end of the plunger is guided by a part n,
whose inclined lower surface rests or takes upon a similarly formed movable block V
capable of being operated by the handle X through the intervention of the screwed
shaft or spindie X'.
Movement of the handle X will thus cause the block V to be moved, either to the
left, or to the right, as the case may be, according to the direction in which the handle
is rotated, thus causing the plunger h to he raised or lowered as required, and conse-
quently accommodating the distance between the top of the plunger and the upper
surface of the block or matrix m, to the length of the article to be forged or
stamped.
When it is required to extract an article from the matrix m, after the stamping
operation, the foot lever S is depressed which causes the whole of the parts V X nc to
be raised, these pieces being in one with the support m', which is guided in its move-
ments between flanged parts of the framing of the machine.
The plunger is thus raised and causes the forged article to move out of the
matrix.

The working of the plunger may be effected by hand instead of by foot.
The operation of extracting or removing the stamped articles may also be effected
in an automatic manner by means of the arrangement shown in Fig. 1, by suitably
regulating the stroke of the plunger.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A stamping machine, the framing of which is formed by two castings (A, B,)
rigidly connected by steel guiding columns (C. C) and pins (c, c) substantially as
described.
2. A stamping machine such as referred to in the preceding claim having combined

conforming to the shape of the guiding columns substantially as described.
3. In a stamping machine of the kind referred to providing the upper casting with
an Arch-piece H having a guide piece M that serves to guide both the extension d of
the central screw and the frame N which connects the two parts of the driving shaft
substantially as described.
4. In stamping machines of the kind referred to providing means for detaching and
raising the stamped article to a determined height, comprising rods T, T, cross
piece P, plunger h, false plunger and tongs" substantially as described.
5. In stamping machines of the kind referred to a lever 1 (with Counterweight) in
combination with tappets t, t¹ for automatically advancing or withdrawing the
claws g, 9 such claws being suspended from connecting rods and serving to grasp the

plunger substantially as described.
6. In a stamping machine the employment of an extractor comprising a plunger
whose height can be regulated by a wedge V and operated by hand or by foot by
means of a pedal (Fig. 4) or in an automatic manner by means of a cross piece con-
nected to the tool holder by two rods, such cross piece operating upon the
plunger either directly or through a false plunger as shown in Figs. 1 and 2
substantially as described.
