Artincial marble and like Substances.
We JEAN BAPTISTE ROTTENSTEIN of 25 Rue Royal Paris in the French Republic,
Doctor of Medicine, and HENRY ARDREN COUSINS of 117 Bentham Road South
Hackney in the County of Middlesex, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the production of inlaid designs or letters in artificial marble
cement plaster of paris and like substances.
For the formation of inlaid letters mosaic or design work the nature of the process
may be briefly described as follows :-
In a glass or other suitable mould is placed in the proper position sufficient of the
plastic material (such as cement) as will cover the letter or design it is desired to
produce. While still soft a templet of the letter or design is placed thereon and a
knife or cutter passed around the templet. When the material has partially set the
superfluous pieces are removed leaving the letters or designs alone in the glass or
mould., If the letters or designs are to be bordered or shaded the chosen material is
filled in around them and cut in the same manner after which the ground is filled in
and the slab finished in the ordinary way.
If preferred the ground is formed of the desired size and while still plastic a sheet
of paper with the outline of a part to he filled in, say in red cut out therefrom is laid
on the ground and gently pressed so as to transfer the outline to the plastic mass. The
part so outlined is then removed and the space filled with the red material and a
second sheet of paper with the outlines of a part to be filled in, say in blue is laid on
the still plastic mass and the operation is repeated and so on until the desired colours
are all inserted.
'
For cloissonné work the design may be first transferred to a piece of wood which is
cut out on the lines which mark the divisions of the different colours by a fret saw or
by other means. The top surface of the wood is oiled or otherwise made non adherent
and the saw cuts are then filled with thin strips of brass zinc or other metal considerably

when subsequently removed the lower edges of the metal will be on the same plane. If
the wood be used as the bottom of a temporary mould, cement or other soft material
is run in until the edges of the metal are quite covered or if preferred while in a
plastic state a slab of plaster may be forced down upon the wood so as to bury the edges
of the metal. In either case when the backing has become hard it will be found that
the metal has become embedded therein and the mass is then laid with the wood
uppermost, said wood being carefully removed when the division lines of metal of the
intended design will be found standing out from the backing to an even plane and such
divisions may be filled in even by unskilled persons with the plastic material of the
desired colour. After the divisions are all filled in the mass is allowed to set and is
then polished in the ordinary manner.
It will be obvious that various materials and colours may be used and copies or
imitations of marble stone wood and other substances reproduced thereby.

Improvements in the Production of Inlaid Designs or Letters in
Artificial Marble and like Substances.
We JEAN BAPTISTE ROTTENSTEIN of 2 Rue Royal Paris in the French Republic
Doctor of Medicine and HENRY ARDREN COUSINS of 117 Bentham Road South
Hackney in the County of Middlesex, 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 :—
This invention relates to the production of inlaid designs or letters in artificial marble
cement, plaster of paris, and like substances.
.
For the formation of inlaid letters, mosaic or design work, the nature of the process
may be described as follows, reference being made to the accompanying drawings which
form part of this specification and in which:
Figure 1 represents a monogram which it is desired to reproduce, and Figures 2, 3
and 4 are the templets or stencil plates made for this purpose, Figure 5 representing
a design which is to be reproduced in cloisonné work.
On a glass or other suitable mould is placed in the proper position sufficient of the
plastic material (such as cement) as will present sufficient surface for the letter or
design it is desired to produce. While still soft a templet of the letter or design is
placed thereon and a knife or cutter passed around the templet. When the material
has partially set, the superfluous pieces are removed leaving the letters or designs alone
on the glass or mould. If the letters or designs are to be bordered or shaded, the
chosen coloured material is filled in around them and cut in the same manner after
which the ground is filled in and the slab finished in the ordinary way.
If it be assumed that the monogram shown in Figure 1 is to be reproduced with the
letter J in red, the letter R in yellow and the letter B in blue, the operation will be
as follows:
The templets as shown in Figures 2, 3 and 4 will be cut out of paper or other suitable
material and will be provided with gauge marks as at a in order that they may be laid
in their proper position. The cement being in a plastic state the templet of letter J is
laid thereon and gently pressed so as to transfer the outline to the cement. The part so
outlined is removed witli a sharp knife or cutter from the body of the cement and the
space filled in with the chosen red material and the templet of the letter R is then laid
in its place and the outline produced. thereby, removed in the same manner and the
space filled in with the chosen yellow material. The templet of the letter B is next
used in the same way and the complete monogram as shown in Figure 1 is thus repro-
duced in colors.
For cloisonné work the design may be first transferred to a piece of wood b which
is cut out on the lines c which mark the divisions of the different colors, by a fret
saw or by other means. The top surface of the wood b is oiled or otherwise made
non-adherent and the saw cuts are then filled with thin strips of brass, zinc, or other

page_text: metal d considerably wider than the thickness of the wood which should be laid upon
a level surface, so than when subsequently removed the lower edges of the metal d will
be on the same plane. If the wood be used as the bottom of a temporary mould,
cement or other soft material is run in until the edges of the metal are quite covered,
or if preferred while in a plastic state a slab of plaster may be forced down upon the
wood so as to bury the edges of the metal. In either case when the backing has
become hard it will be found that the metal d has become embedded therein, and the
mass is then laid with the wood uppermost, said wood being then removed from the
cement below, when the division lines of metal of the intended design will be found
standing out from the backing of cement to an even height, and such divisions may
be filled in even by unskilled persons with the plastic material of the desired color.
After the divisions are all filled in the mass is allowed to set and is then polished in the
ordinary manner, the edges of the metal strips being left flush with the rest of the
material in which they plainly show with pleasing effect.
In place of employing a temporary foundation of wood as described we may use a
slab of wax, clay, or similar plastic material on which the design would be first
outlined or traced, said outline being subsequently used to indicate the position for
the metal strips which would then be pressed into the plastic material on the lines
of same.
Where it is desired to produce, say a panel, both sides of which are to be seen, the
coloured material is filled in while the brass strips remain in the wood foundation and
when this is set the slab is turned over, the wood removed, and the other half of the
strips then exposed are filled up level in a similar manner and with the same or different
colours, both sides being subsequently ground and polished.
It will be obvious that various materials and colours may be used and copies
or imitations of marble, stone, wood, and other substances reproduced thereby.
'
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is :
1st In the production of inlaid letters or designs in artificial marble and like
substances the use of one or more templets which are pressed upon the plastic mass,
the parts outlined thereby being removed and the space so left being filled in with
plastic material of the desired colour as set forth.
2nd In the production of inlaid letters or designs in artificial marble and like
substances for cloisonné work, the use of one or more temporary foundations bor
moulds in which the design is first cut, said cuts being subsequently filled with
brass, zinc, or other projecting strips d which are then embedded in a backing (or
where both sides are to be seen, filled in with the required colored material), the
foundation being then removed, and the spaces around and between the strips
so exposed being filled with the required coloured material, the surface or surfaces
being then ground and polished, all as set forth.
