Year: 1857

page_text: LETTERS PATENT to Frederick Walton, of Wolverhampton, in the County
of Stafford, Manufacturer, and John Pinson, of Wolverhampton, afore-
said, Machinist, for the Invention of "NEW OR IMPROVED MACHINERY FOR
STAMPING OR RAISING METALS."
Sealed the 28th July 1857, and dated the 22nd May 1857.
PROVISIONAL SPECIFICATION left by the said Frederick Walton
and John Pinson at the Office of the Commissioners of Patents, with
their Petition, on the 22nd May 1857.
We, FREDERICK WALTON, of Wolverhampton, in the County of Stafford,
5 Manufacturer, and JOHN PINSON, of Wolverhampton, aforesaid, Machinist,
do hereby declare the nature of the said Invention for "NEW OR IMPROVED
MACHINERY FOR STAMPING OR RAISING METALS," to be as follows:-
Our said Invention consists in the arrangement of the parts of stamping
machinery, herein-after described, whereby the process of stamping or raising
O metals may be more readily and economically.effected than by the ordinary
machinery. We attach the force or concave die to the ram or hammer of
the stamp, and the convex die is fixed on the bed of the stamp. The said
convex or lower die is situated in a fixed rim or case, in which it is capable of

page_text: being raised or lowered by the means herein-after described. When a sheet
or plate of metal is to be operated upon, the convex die is so situated in its
rim or case that it projects but little above the said rim or case; the force or
hammer is allowed to descend, and the plate of metal is partially raised by
being struck upon the projecting part of the lower die. When the hammer
and force are raised the lower die is elevated in its rim or case, and the
hammer being again brought down the plate is further raised. The elevation
of the lower die in its rim or case is continued during the stamping process
until the plate of metal has been raised to the required degree. When the
article to be made is deep, several forcers and lower dies of different depths may
be employed. We prefer to effect the raising of the lower die by making in
its lower side an incline, and causing the said incline to rest on a wedge sliding
horizontally through the side of the rim or. case in which the lower die rests. The
motion of the wedge may be effected by a screw, and the said screw may be
either actuated by hand or geared to the stamp so as to be self-acting. Plates
of metal raised according to our Invention require but little annealing, and
the metal is not so much injured as in the ordinary method of raising metals..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed"
by the said Frederick Walton and John Pinson in the Great Seal
Patent Office on the 19th November 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
WALTON, of Wolverhampton, in the County of Stafford, Manufacturer, and
JOHN PINSON, of Wolverhampton, aforesaid, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of May, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year. of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Frederick Walton and John Pinson, Her special licence that we, the
said Frederick: Walton and John Pinson, our executors, administrators, and
assigns, or such others as we, the said Frederick Walton and John Pinson,
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 "NEW OR IMPROVED MACHINERY

page_text: FOR STAMPING OR RAISING METALS," upon the condition (amongst others) that we,
the said Frederick Walton and John Pinson, our executors, or administrators,
by an instrument in writing under our or their hands and seals, or under the
hand and seal of one of us or them, 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. Frederick Walton, 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 :--
Our Invention consists of the arrangement or arrangements of the parts of
stamping machinery, herein-after particularly described and represented in the
accompanying Drawing, by which arrangement or arrangements the process of
stamping, or raising metals may be more readily and economically.effected than
by the machinery ordinarily employed.
Figure 1 of the accompanying Drawing represents in elevation the lower
part of a stamping machine.constructed according to our Invention; Figure 2
represents the bed of the same in vertical section; and Figure 3 represents a plan
of the bed of the machine. We attach the force or concave die a to the ram or
hammer of the stamp 6, and we fix the convex die c on the bed of the machine.
The said convex or lower die c is situated in a fixed rim or case d, the said
rim or case d being secured in its place by the set screws e. When a sheet
or plate of metal is to be operated upon, the convex die c is so situated in its
rim or case, as shown in Figures 1 and 2, that it projects but little above the
said rim or case. The force a and hammer b are allowed to descend, and the
plate of metal is partially raised by being struck upon the projecting part of
the lower die c. When the force and hammer are raised the lower die is
elevated in its; rim or case by the methods herein-after explained, and the
hammer b and force a being again brought down the plate of metal is further
raised. The elevation of the lower die c in its rim or case d is continued
during the stamping process until the plate of metal operated upon has been
raised to the required degree. When the articles to be raised are deep,
several forces, and lower dies of different depths may be employed, and
the article, annealed from time to time. f, g, and h, Figure 4, repre-
sent a series of such lower dies, the forces or concave dies to be used
therewith varying, in depth so as to, correspond to the dies f, g, h, respec-

page_text: tively. The lower die c may be raised in a variety of ways, but the
methods represented in the Drawing are those which we prefer to employ
and which we have found to answer well in practice. The die c rests
upon a shoulder in the rim or case d, as represented in Figure 1.
A cylin-
drical block i is situated in the cylindrical opening of the rim or case d and 5
immediately under the die.c. A series of wedges k, l, m, n, are situated in a.
cavity in the bed o of the press, the said wedges being arranged in the manner
represented in Figure 2, and the said cylindrical block i rests upon the said
wedges k, l, m, n, as represented. The wedges m, n, are connected by a dove-
tail with the slide p, and a screw q on the end of the axis r engages in the 1
slide p. By the turning of the axis r the slide p may be made to advance
towards the axis of the stamp, and the wedges m, n, sliding upon the wedges
k, l, raise the block i and die c. Instead of the wedges k, l, m, n, one wedge
working on a fixed incline may be employed, but we prefer the method
described and represented. After each descent of the hammer b and force a,
the winch s may be turned round once, by which the die c may be raised
to the requisite distance. We sometimes raise the lower die c by the
self-acting mechanism represented connected with the stamp in Figure 1.
On the axis r we place a pinion t, with which pinion a toothed wheel
u engages; w is a lever, the motion of which is tramsmitted through
the connecting rod x to the lever y; a coiled spring z holds the lever y
in the position represented. A catch 1 on the hammer 6 strikes against
the end w¹ of the lever was the hammer b is raised, raising the end wi
of the said lever w. The end of the lever y is at the same time
raised, and engaging under one of the pins 2 on the wheel u, commu-
nicates to the said wheel u a partial rotation. This motion is transmitted
by the pinion t to the axis r, and the partial raising of the die c is
thereby effected. The joint 3 in the lever y enables the end y¹ to pass and
engage under the pins 2. The catch 1 turns upon an axis as represented, so
that on the descent of the hammer b it passes the lever w by turning upon its
axis. When the catch 1 has passed the lever w it resumes its position as
represented in the Drawing. Plates of metal stamped or raised by machinery
constructed according to our Invention, require. but little annealing, and the
metal is not so much injured as in the ordinary method of raising metals.

Having, now described the nature of our Invention, and the manner of
carrying the same into effect, we wish it to be understood that we do not limit
ourselves to the precise details herein described and represented in the Draw-
ing, as the same may be varied without departing from the nature of our

page_text: Invention; but we claim as our invention the new or improved machinery for
stamping or raising metals herein-before described and illustrated in the
accompanying Drawing, that is to say, stamping machinery in which the
convex die placed on the bed of the stamp is gradually raised during the
stamping process either by hand or by mechanism actuated by the hammer of
the stamp.
In witness whereof, I, the said Frederick Walton, have hereunto set my
hand and seal, this Eighteenth day of November, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
GEORGE SHAW.
