We, ARTHUR RITTER VON KLINKOSCH, and ISIDOR RITTER VON KLINKOSCH both
of II., Afrikanergasse, 5, Vienna, Austria, Gold and Silver ware Manufacturers
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 consists in a novel process or method of making spoons and table-
forks of silver and of other metals or alloys, this novel method affording possibility
for manufacturing the said objects in a quicker simpler and cheaper manner than
heretofore.
The process used hitherto is the following one: By means of cutters and punches
having plain or even meeting surfaces, blanks are punched out of the metal sheet,
and these blanks are afterwards stamped in dies or matrices which have likewise plain
meeting faces and into which the object to be made is cut approximately only to
the required forms and dimensions. The bur left by the stamping operation is
removed by means of the cutter and punch, and after this "the blanks are stamped
between dies, the meeting faces of which are of undulating form, according to the
curvature, which the finished object is to have, and into which the form and
adornments of the said object are exactly cut. The bur again formed is filed off
by hand, and finally the pieces are ground and polished by hand.
According to the present invention, the manufacture of all kinds of spoons and
table-forks, in any shape and size, requires a considerably less number of successive
operations. The process is as follows:-
Straight metal pieces of uniform convenient thickness and of rectangular form or:
cut approximately to the contour of the spoon are directly stamped between dies,
the meeting faces of which are of undulating form, according to the curvature to
be given to the object, and into which the shape and dimensions of the article to
be made are exactly formed or cut, the surfaces of the cuts, by which the article
is shaped by stamping, being highly polished. The bur, which is formed by the

page_text: stamping operation, is cut off by means of cutters and punches, the meeting or
shearing edges of which are likewise made undulating according to the curvature
of the article to be made, the punches having cut or formed into their under surface
an exact and highly polished die, answering to the upper surface of the object
under treatment. The bur having been removed, the article is ready for sale.
Extraordinarily large and heavy pieces have to go through the described process
several times.
From the above statement it will be understood that this novel process does away
with all filing, grinding and polishing, as the high polish of the steel dies passes
onto the object stamped; thus the three most costly operations, which hitherto could
only be done by hand are eliminated.
In the annexed sheet of drawings, Figures 1 and 2 are perspective views of
longitudinal sections of the dies A and B, the acting surfaces a of which are highly
polished.
Figure 3 shews in side elevation and on a smaller scale the two superposed dies.
Figures 4 and 5 represent the cutter C and the punch D, having both undulating
meeting or shearing edges, and the cutter C being provided with an aperture c, while
the punch D has cut in its under surface a highly polished matrix or mould of the
upper surface of the object to be made with all its ornamentations, in order to prevent
the similar ornamentations, stamped on the object by means of the dies, from being
injured or flattened on the bur being sheared off.
Figure 6 shews the cutter and punch in side elevation on a smaller scale.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
First. A process or method of manufacturing spoons and table-forks of all kinds and
shapes, of any suitable metal or alloy, the said process consisting in stamping metal
pieces of convenient size between dies made of hardened steel-these dies having
undulating meeting faces according to the curvature of the article to be made, and
having all forms and ornamentations of the said article exactly formed or cut into
them and the cut surfaces highly polished--and in afterwards cutting off the bur
formed at the stamping operation by means of cutters, the surface of which is
likewise undulating according to the curvature of the article, and punches, the pressing
surface of which is formed or cut according to the shape of the upper surface of the
object, and highly polished.
Second. For carrying into practice the claimed process or method, dies, cutters
and punches, made of hardened steel, having their meeting faces made of undulating
form according to the curvature of the article to be made, and their pressing surfaces
formed or cut according to the form of the said object and highly polished, substantially
⚫as set forth.
