PROVISIONAL SPECIFICATION.
An Improved Process for Manufacturing Ornamental Metallic
Articles.
I, LINCOLN HAUSMANN, of I Börsegasse 1 Vienna, in the Empire of
Austria, Merchant do hereby declare the nature of this invention to be as
follows:-
Hitherto three processes only have been in use for manufacturing ornamented
metallic articles, viz., casting galvanoplasty and stamping. Owing to the great
expenditure they involve, the two first named processes are not suitable for the
production of articles to be used in large quantities, in particular, the galvano-
plastic process necessitates the operations of forming the article in wax, and of
making it conducting by means of plumbago which operations are uncertain costly
and time wasting. The stamping process gives rise when articles of large
dimensions are dealt with, to heavy expenses and to great technical difficulties,
owing to the necessity of employing steel stamps.
This invention relates to a process the result of which is to reduce the cost of
manufacturing articles embossed or stamped; for this purpose, sheet-metal having
the thickness of paper is employed for manufacturing said articles such sheet-metal
being afterwards provided with a lining in order to give it the necessary stiffness
and resistance.
Said lining will be preferably obtained by the galvanoplastic process, the metal
being precipitated from metallic salts: but, according to the nature of the articles,
linings cast or pressed on the back of the formed metal-sheet may be made use of,
such linings consisting either of metal or of a paste or pulp that afterwards grows
hard, such as wood-fibre, cement, plaster, papier-maché and the like.
Owing to the circumstance that the shaping operation proper is applied to sheet-
metal having only the thickness of paper, the manufacturing process extremely
simplified; for instance, if articles of large dimensions are to be stamped, stamps
of pressed paper may be made use of.
Besides the energy required for the stamping is reduced, by which the process
above mentioned results in a very cheap product.
After the thin-metal sheet having designs embossed, curved or perforated, has
been subjected to the shaping operation that gives it the required shape, it is
strengthened by the addition of a lining. If for this purpose use is made of the
galvanoplastic process, and if the lining has to be laid only on the back of the
metal-sheet the face of the latter is insulated.
If the strengthening lining is to be pressed on or cast, the shaped metal-sheet is
first placed into the matrix of its press, in order to prevent the delicate embossings
or hollow designs of its surface from being damaged during the pressing or casting
operation.

I, LINCOLN HAUSMANN, of I Börsegasse 14 Vienna, in the Empire of
Austria, Merchant, 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 :—
Hitherto three processes only have been in use for manufacturing ornamental
metallic articles, viz.,-casting, galvanoplastic and stamping. Owing to the great
expenditure they involve, the two first named processes are not suitable for the
production of articles to be used in large quantities in particular, the galvano-
plastic process necessitates the operations of forming the article in wax, and of
making it conducting by means of plumbago, which operations are uncertain, costly
and involve great waste of time. The stamping process gives rise when articles of
large dimensions are dealt with, to heavy expenses and to great technical difficulties,
owing to the necessity of employing steel stamps.
This invention relates to a process the result of which is to reduce the cost of
manufacturing articles embossed or stamped for this purpose, sheet metal having
the thickness of paper is employed for manufacturing said articles, such sheet-metal
being afterwards provided with a lining in order to give it the necessary stiffness
and resistance.
The said lining is preferably obtained by the galvanoplastic process, the metal
being precipitated from metallic salts; but, according to the nature of the articles,
linings cast or pressed on the back of the formed metal sheet may be made use of
such linings consisting either of metal or of a paste or pulp which ultimately
hardens such as wood fibre, cement, plaster papier-maché and the like.
Owing to the fact that the shaping operation proper is applied to sheet-metal
having only the thickness of paper, the manufacturing process is very much
simplified, for instance if articles of large dimensions are to be stamped, stamps of
pressed paper may be made use of.
Moreover the energy required for the stamping is reduced, by which the process
above mentioned results in a very cheap product.
After the thin metal-sheet, which is provided with suitable designs embossed,
carved or perforated therein, has been subjected to the shaping operation which
gives it the required shape it is strengthened by the addition of a lining. If, for
this purpose, use is made of the galvanoplastic process, and if the lining has to be
laid only on the back of the metal-sheet the face of the latter is insulated.
If the strengthening lining is to be pressed on or cast the shaped metal-sheet is
first placed into the matrix of its press, in order to prevent the delicate embossings
or hollow designs of its surface from being damaged during the pressing or casting
operation.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. A process for manufacturing ornamental metal articles said process consisting
in stamping or pressing a metal-sheet as thin as paper, and afterwards strengthening
it either by a metallic lining obtained galvanically or by casting or pressing on it
a lining made of metal or of a paste or pulp which afterwards becomes hard.
2. The herein described improved metallic articles formed by first shaping a thin
metal-sheet and then strengthening it by the process hereinbefore described.
