PROVISIONAL SPECIFICATION.
Improvements in Inlaying Metals.
I FERDINAND BACнSCHMID of Bienne in the Republic of Switzerland Manufacturer
do hereby declare the nature of this invention to be as follows:-
My invention for improvements in inlaying metals has for its object to inlay one
metal with another in such manner that the inlaid metal can be bent, formed,
soldered or otherwise treated in being formed into the various articles it is desired
to make without the inlaying metal or metals becoming separated or loosened.
The metal forming the base of the article to be manufactured is first inlaid with one
or more metals of distinctive colour or colours and is then converted into plates bands
or pieces of other suitable shape which will afterwards serve for the manufacture of
the required article.
In inlaying the base metal according to my invention, the inlaying metal or metals
is or are first. sweated or melted on the base inetal and are then passed between rolls
or under a press on which the pattern is engraved or embossed in relief, the different
parts of the pattern being raised on the rolls or die of the press to such height that
the inlaying metal or metals is or are pressed into the base metal so that at the desired
parts the upper surface of the inlaying metal or of the desired inlaying metal is
level with the original surface of the base metal. The projecting parts of the inlaying
metals are then cut away to the level of the surface of the base metal. When desired
to ornament the plate or base metal so that the ornaments appear in relief the roller
or die of the press must be engraved accordingly.

Improvements in Inlaying Metals.
I FERDINAND BACHSCHMID of Bienne in the Republic of Switzerland Manufacturer
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:-
My invention for improvements in inlaying metals has for its object to inlay one
metal with another or with others in such manner that the inlaid metal can be bent,.
formed, soldered or otherwise treated in being formed into the various articles it
is desired to make without the inlaying metal or metals becoming separate or
loosened.
The metal forming the base of the articles to be manufactured is first inlaid with
one or more metals of distinctive colour or colours and is then converted into plates,
bands or pieces of other suitable shape which will afterwards serve for the manufacture
of the required article.
In inlaying the base metal according to my invention, the inlaying metal or metals
is or are first sweated or melted on the base metal and are then passed between rolls or
under the die of a press on which the pattern is engraved or embossed in relief, the
different parts of the pattern being raised on the rolls or die of the press to such height
that at the desired parts the inlaying metal or metals is or are pressed. into the base
metal so that the upper surface of the inlaying metal or of the desired inlaying metal
is level with the original surface of the base metal. The projecting parts of the inlaying
metal or metals are then cut away to the level of the surface of the base metal. When
desired to ornament the plate or base metal so that the ornaments appear in relief
the roller or die of the press must be engraved accordingly.

Fig. 1 is a cross section of a base metal having secured to its top surface one
inlaying metal.
Fig. 2 is a cross section of base metal and inlaying metal shewing the inlaying metal
impressed into the base metal and
Fig. 3 is a cross section of the finished plate manufactured according to my
.invention.
Figs. 4, 5, and 6 are similar views to Figs. 1, 2 and 3 respectively but shewing two
inlaying metals applied to the base metal.
When one inlaying metal only is employed, the pattern of the ornament is embossed
or raised on the rolls or on the die of the press to such a height that when the base.
metal a on the upper surface of which the inlaying metal b has been sweated or other-
wise suitably secured as shewn in Fig. 1 is passed between the rolls or squeezed in
the press the embossed portions press the inlaying metal into the base plate a to
such a depth that the upper surface of the inlaying metal at these points is level
with the original upper surface of the base metal a as clearly shewn, in Fig. 2. The
parts of the inlaying metal & standing above the base metal a are then cut away so as to
leave a flat surface as shewn in Fig. 3.
When two inlaying metals are employed the one is sweated on the upper
surface of the base metal a and the other c on the upper surface of the metal b
as shewn in Fig. 4.
The pattern of the ornament is raised or embossed on the rolls or the die to such
depths that when the plate shewn in Fig. 4 is passed between the rolls or put under
the press some parts are depressed so that the upper surface of the metal bis level
with the original surface of the metal a and other parts so that the upper surface of the
metale is level with the original surface of the metal a as shewn in Fig. 5. The
projecting portions of the inlaying metals b and c are then cut away and leave an orna-
mental flat surface as shown in Fig. 6. The inlaying metals should be of distinctive
colours with respect to the base metals and also to each other. If desired inore than
two inlaying metals may be employed the process of manufacture being similar to
that above described.
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. The process of manufacturing ornamental metal surfaces consisting in sweating
the inlaying metal or metals on to the base metal and then in depressing the desired
parts of the compound plate to such depth or depths that the upper surfaces of the
desired inlaying metal is at the level of the original surface of the base metal and
finally in removing the projecting parts of the inlaying metal or metals, substantially
as described.
2. The construction of an ornamental metal surface, consisting of a base metal with
one or more inlaid metal patterns which are sweated upon and form an even surface
with the said base metal substantially as described.
3. The inlaying of metal surfaces substantially as described with reference to the
drawings.
