PROVISIONAL SPECIFICATION.
Improved Mould for the Production of Inlaid Designs on Tiles.
I WILLIAM HENRY MCLACHLAN of 8 Trouville Road Clapham Park in the
County of Surrey Builder do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to produce a simple and effective mould for the
production of inlaid designs on tiles in lieu of the clumsy and costly moulds now
in use.
According to this invention I take a flat plate of copper, gun metal or other
suitable material large enough to cover the tile and to this plate I attach by screws
rivets or other suitable means of fastening a flange or flanges all round the back of
the plate or the flanges if the plate is made of gun metal or other cast material may
be cast in one piece with the plate. I take also another plate of copper or other
suitable material having a handle attached to the back thereof and adapt the said
plate to slide easily between the flanges on the back of the first mentioned plate,
but having no movement sideways and to this last mentioned plate hereinafter called
the lower plate I attach pieces of suitable metal of the shape of those portions of
the design which are of one color and I form in the first mentioned or upper plate
orifices to correspond with the above mentioned pieces attached to the lower plate.
The lower plate has a movement of from tot of an inch and this movement is
limited by suitable moveable stops. When the lower plate is in its highest position
the upper surface of the mould is all flush but when the said plate is in its lower
position the upper surface of the mould shews the design or a portion of the design
sunk therein these depressions are filled with the colored material to be inlaid and
the superfluous material removed and while the material is still plastic the mould is
turned over and placed on to the tile the lower plate which now uppermost pushed
down while the mould is raised leaving the colored design on the tiles, a similar
mould is used to deposit the next colored portion and so on as many moulds being
used as there are inlaid colors.
I provide also a means for correctly registering
each portion of the design and I further provide suitable handles for lifting the
moulds. By removing the stops the lower plate may be removed for cleaning.
Dated the 9th day of October 1890.

Improved Mould for the Production of Inlaid Designs on Tiles.
1, WILLIAM HENRY MCLACHLAN of 8 Trouville Road Clapham Park in the
County of Surrey, Builder, 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:-
The object of this invention is to produce a simple and effective mould for the
production of inlaid desigus on tiles in lieu of the clumsy and costly moulds now
in use.
According to this invention I take a flat plate of copper gun metal or other
suitable material large enough to cover the tile and to this plate I attach by screws
rivets or other suitable means of fastening a flange or flanges all round the back of
the plate or the flanges if the plate is made of gun metal or other cast material may
be cast in one piece with the plate. I take also another plate of copper or other

page_text: different colors and by filling the eight depressions shewn in Fig. 5 with materials
of different colors sixteen distinct colors might be inlaid by means of only two
moulds.
In some cases it is necessary to fill one or more depressions with material of two
or more colors in which cases I fix strips of thin copper or other suitable material
to the pieces c c to separate the differently colored portions of material from each
other in the usual way.
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
The improved mould for the production of inlaid designs on tiles substantially as
described and shewn.
