Septimus Vaughan, of West Bromwich, in the County of Stafford,
Manufacturers, for the Invention of "IMPROVEMENTS
FOR STAMPING METALS."
IN MACHINERY
Sealed the 4th June 1875, and dated the 24th December 1874.
PROVISIONAL SPECIFICATION left by the said John Vaughan at the
Office of the Commissioners of Patents, with his Petition, on the
24th December 1874.
I, JOHN VAUGHAN, of the Firm of John, Joseph, and Septimus
Vaughan, of West Bromwich, in the County of Stafford, Manufacturers,
do hereby declare the nature of the said Invention for
"IMPROVEMENTS
IN MACHINERY FOR STAMPING METALS," to be as follows:-
My said Invention consists of the arrangements or combinations of
parts of machinery for stamping metals herein-after described, whereby
the said machinery is made wholly or in part automatic. I attach the
hammer of the stamp to a metallic strap or band passing over a large

is pressed tightly against the said pulley, when the pulley carries the
band with it and raises the hammer attached to the band.
Centre.
The mechanism for pressing the band tightly against the rotating
pulley and releasing it at the required times is constructed and works as
follows: Immediately opposite the pulley and working in the same
plane is a roller carried by a vertical arm, the latter turning upon a
The band to which the hammer of the stamp is attached is
between the pulley and the roller. The said roller by the turning of the
arm carrying it on its centre can be made to press the band against the
groove in the pulley, or it can be removed to a short distance from the
said pulley, when the band will be released. By means of a lever
turning on the same centre as the arm carrying the roller the roller can
be brought into the required position, but I prefer to connect a spring to
the said lever so as to press the roller against the band and pulley. The
roller and parts connected therewith are situated at the level of the
pulley, and a vertical connecting rod attached to the lever descends to
near the bed of the stamp. Near the upper end of this commeeting rod
is a tappet, and its lower end is connected to a short lever which may be
acted upon by hand or by the hammer of the stamp.
The action of the parts is as follows:--In their normal state the roller
presses the band against the pulley, and the latter carrying the band
with it effects the raising of the hammer. But as the hammer
approaches the end of its up-stroke it strikes against the tappet on the
connecting rod, and lifting the lever withdraws the roller from the band
am the hammer falls. The lever is maintained in its raised position
until the hammer nearly reaches the end of its fall, when acting on
the short lever at the bed of the stamp it liberates the lever giving
motion to the roller, when the spring described presses the roller against
the band and pulley and the hammer is again raised. The raising and
letting fall of the hammer may thus be effected automatically, but the
working of the stamp may be controlled by the action of the hand on
the short lever.

TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, JOHN
VAUGHAN, of the Firm of John, Joseph, and Septimus Vaughan, of
West Bromwich, in the County of Stafford, Manufacturers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of December, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said John Vaughan, Her
special license that I, the said John Vaughan, my executors, admi-
nistrators, and assigns, or such others as I, the said John Vaughan,
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 STAMPING METALS," upon the condition
(amongst others) that I, the said John Vaughan, my executors
administrators, 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.
or
NOW KNOW YE, that 1, the said John Vaughan, 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 thereof, that is to say :-
My said Invention consists of the arrangements or combinations of parts
of machinery for stamping metals herein-after described, whereby the said
machinery is made wholly or in part automatic. 1 attach the hammer
of the stamp to a metallic strap or band passing over a large pulley
driven by steam or other power. The rotation of the pulley takes place

page_text: without giving motion to the band, excepting when the said band is
pressed tightly against the said pulley, when the pulley carries the band
with it and raises the hammer attached to the band.
The mechanism for pressing the band tightly against the rotating
pulley, and releasing it at the required times is constructed and works as
follows: Immediately opposite the pulley and working in the same
plane is a roller carried by a vertical arm, the latter turning upon a
centre. The band to which the hammer of the stamp is attached is
between the pulley and the roller. The said roller by the turning of the
arm carrying it on its centre, can be made to press the band against the
groove in the pulley, or it can be removed to a short distance from the
said pulley when the band will be released. By means of a lever turning
on the same centre as the arm carrying the roller, the roller can be
brought into the required position, but I prefer to connect a spring to
the said lever so as to press the roller against the band and pulley. The
roller and parts connected therewith are situated at the level of the
pulley, and a vertical connecting rod attached to the lever descends to
near the bed of the stamp. Near the upper end of this connecting rod
is a tappet, and its lower end is connected to a short lever which may be
acted upon by hand or by the hammer of the stamp.
The action of the parts is as follows:-In their normal state the roller
presses the band against the pulley, and the latter carrying the band
with it effects the raising of the hammer. But as the hammer
approaches the' end of its up stroke it strikes against the tappet on the
connecting rod, and lifting the lever withdraws the roller from the hand
and the hammer falls. The lever is maintained in its raised position
until the hammer nearly reaches the end of its fall, when acting on the
short lever at the bed of the stamp it liberates the lever, giving motion
to the roller, when the spring described presses the roller against the
band and pulley and the hammer is again raised. The tappet described
may be replaced by a lever, and the rising hammer be made by striking
the said lever to withdraw the pressing roller from the band.
raising and letting fall of the hammer may thus be effected automatically,
but the working of the stamp may be controlled by the action of the
hand on the short lever.
The
Having explained the nature of my Invention will proceed to
describe with reference to the accompanying Drawings the manner in
which the same is to be performed.

The same letters of reference indicate the same parts in the several
Figures of the Drawings.
The stamping machinery represented is such as is used for stamping
or forging metals for various purposes, such for example as the
stamping or raising of articles of sheet metal, the manufacture of gum
implements, the manufacture of edge tools, and the like, but my
improvements may be applied to other stamping machinery where it is
wished to raise and let fall a hammer or ram automatically.
a is the metallic strap or band passing over the large pulley b driven
by steam or other motive power. One end of the said metallic strap or
band is attached to the hammer e, and the free or unconnected end of
the strap or band after passing over the pulley b works in the guide
box d. When the strap or band a is pressed tightly against the pulley
the said pulley rotating in the direction of the arrow carries the band a
with it and raises the hammer c, as represented in Figure 4. On
removing the pressure from the band a the hammer falls.
i
The pressing of the hand a against the pulley b and the removal of the
pressure are effected as follows:- is a small pressing roller carried by
the forked arm /, /. (see Figure 3), the said arm being fixed on the
horizontal rocking shaft g. On the said shaft g is a lever h, the free end
of which passes through the upright of the stamp and is connected
through the coiled spring with a vertical connecting rod k, which
rud descends to near the bed of the stamp and is jointed to the hand
lever l. The said lever 1, when the stamp is in action is engaged under
a fixed notch m. The lever ▲ is thereby pulled down, and by acting
through the rocking shaft g and arm / presses the band a against the

is disengaged from the notch # the hammer of the stamp is thrown out
of action. The working of the stamp may thus be controlled by the
Workman.
"'
and arm 7
By means of a second lever a connected through the rod
with the rocking shaft g the lifting of the lammer e is made to with-
draw the pressing roller e from the band a, and release the said band
and allow the hammer to fall. The pressing roller e is held in its with-
drawn position (see Figure 4) during the descent of the hammer, and
permitted at the proper time to return to its normal or pressing position
to again act on the band by the action of the lever 2, 77. The lower end
of the arm of the lever r, P. is situated near the bed of the stamp,
and the said lower end is pressed inwards by the spring s. The inner
face of the lower end of the lever 2, 12, has a projection or tappet & upon
it, which is acted upon by the falling hammer e when the latter is near
the end of its fall. Near the upper end of the arm 2 of the lever 1, 1º,
is a support at, which at the proper time is brought under the end of the
lever h, and made to support the said lever so as to hold the pressing
roller e out of contact with the band a.
The action of the parts is as follows:-When the several parts are in
the respective positions represented in Figures and the pressure
roller e is forcibly pressing the band a against the groove in the pulley b,
and the hammer e is about to be raised. As the hammer c approaches
the end of its up stroke it strikes against and lifts the lever #, and gives
motion through the rod p and arm o̟ to the rocking shaft g. By the
motion of the rocking shaft 'y the lever is raised and the pressing
roller e withdrawn from the band a, and the said band is no longer
pressed on the pulley b, and the hammer descends. By the lifting of
the lever / it is brought above the support # on the side lever 7, 72, which
lever 2, 1º, by the action of its spring » presses the support # under the
said lever , and supports it in the position represented in Figure 4, and
thereby holds the pressing roller e in its withdrawn position during the
descent of the hammer. The position of the support a under the lever l
is best seen in Figure 5. When the hammer nearly reaches the end of
its fall it acts against the tappet or projection 7 on the end of the lever
1, 72, and presses the said lever outwards and compresses the spring s.
The support is thereby withdrawn from under the lever h, which
lever is pulled down by the expanded spring i, and the roller c again

page_text: pressed into contact with the band and the latter carried with the
pulley b, the parts now occupying the respective positions represented in
|Figures 1 and 2, when the hammer & is again raised and the operations
described are repeated.
Instead of pressing the band a directly against the pulley the said
band may pass between the pressing roller and a second roller and be
pressed against the said second roller to raise the hammer. This modifi-
cation is represented in Figure 6, where the second roller against which
the band a is pressed by the pressing roller e is marked. When the
band a is pressed against the roller it is at the same time tightened

same letters of reference.
are driven by
The other parts of the mechanism, Figure 6.
Figure 7 represents another modification of my Invention in which
the pressing roller is omitted.
In this arrangement I connect the end of the band a to the end of the
arm or lever a, the said arm or lever being connected by the link w to
the lower lever n. The pulling down of the lever by the spring and
rodi, k, causes a córresponding motion to be given to the lever o
through the shaft g, armi q, rod p, and lever a, and the pulling down of
the lever causes the band to be tightened on the pulley b and the
hammer c raised. When the lever is lifted by the rising of the
hammer in the manner herein-before described the pressure on the arm
or lever and band is relaxed and the pulley now rotates without
carrying the band with it, and the hammer falls. The arrangement for
holding the lever in its raised position and through the lever the
arm or lever is the same as herein-before described.
Although I prefer to make the strap or band a of thin sheet steel or
iron yet I do not limit myself to the use of these materials, as wire or
hempen rope, or a strap, band, or rope of other strong and flexible
material may be employed with like effect.
Although I have represented the best arrangements with which I am
acquainted for causing the metallic strap or band to be pressed upon and
released from the driving pulley or pulleys, yet I do not limit myself to
the details of the said arrangements, as other arrangements of parts may

page_text: be devised for effecting the objects described without departing from the
nature of my Invention.
Having now described the nature of my Invention and the manner in
which the same is to be performed, I wish it to be understood that 1
claim as my Invention of improvements in machinery for stamping
metals, the construction and combinations of
parts herein-before
described and illustrated in the accompanying Drawings for auto-
matically working the hammers of stamps or stamping machinery, that
is to say, attaching the hammer of the stamp to a strap, band, or rope
passing over a rotating pulley driven by steam or other power, and
pressing the said strap, band, or rope forcibly against the said rotating
pulley for raising the hammer and releasing the strap, band, or rope at
the proper time for letting the hammer fall by means of the mechanical
arrangements of parts constructed and operating substantially as
described and illustrated, also the modifications described with respect
to Figures 6 and 7 of the accompanying Drawings.
In witness whereof, I, the said John Vaughan, have hereunto
set my hand and seal, this Fourteenth day of June, in the
year of our Lord One thousand eight hundred and seventy-
tive.
