I do hereby declare the nature of my invention for A METHOD OF MAKING AND
ORNAMENTING IN RELIEF OR INTAGLIO PLASTIC CLAY SLABS, TILES, PLAQUES,
FRAMES, AND ARCHITECTURAL ORNAMENTS to be as follows:-
+
The construction of the press to be the same as in the common. Lithographic
press with the addition of a Cylinder in the place of the scraper; if necessary and
with a coil of gas jets. under the bed of the press to keep the mould dry if
required.
г
The bottom mould is to be made of Plaster of Paris or Metal cast into an iron
rim. The bottom rim has raised or sunk points by which the top rim can be
perfectly adjusted. The top rim is of the, thickness required for the Slab, Tile &c
and its sides are slightly beveled so that it may be easily lifted off the pressed Slab,
Tile &c. The top rim may also have a number of cutters arranged as intersecting
bars só as to form a number of small tiles at once.
The mould is placed on the bed of the press and the top rim fixed in possition by
the points.
The Clay having been cut roughly to the required size and thickness is placed in
or on the top frame and the pressure having. been adjusted it is passed under the
Scraper or Cylinder once or twice, using the screw at the top for increased pressure;
If it is found necessary a tympanum of Leather or Cloth may be used If the Relief
is very high à ram of Wood or Metal may be used, made somewhat to the shape of
the ornament to be pressed' out of the lower Mould and fitted on to the top frame>
after the Clay is on by means of points as in the lower Mould. :
The top rim is now withdrawn and a Plaster of Paris bat laid on the top of the
Clay Slab or Tile &c. The Mould and plaster bat turned over and the mould lifted'
off the Clay Slab or Tile &c and returned to the bed of the Press.

I do hereby declare the nature of my invention for A METHOD OF MAKING AND
ORNAMENTING, IN RELIEF OR INTAGLIO, PLASTIC CLAY SLABS TILES, PLAQUES,
FRAMES, AND ARCHITECTURAL ORNAMENTS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement
The construction of the Press to be the same as in the common Lithographic
press with the addition of a Cylinder in the place of the Scraper if necessary and
with a coil of gas jets under the bed of the press to keep the mould dry if required
The bottom mould is to be made of Plaster of Paris or Metal cast into an iron rim
The rim of the bottom mould has raised or sunk points by which a top rim can be
perfectly adjusted.
The top rim is of the thickness required for the Slab, Tile &c, and its sides are
slightly beveled so that it may be easily lifted off the pressed Slab, Tile &c.
The top rim may also have a number of cutters arranged as intersecting bars so
as to form a number of small tiles at once.
The mould is placed on the bed of the press and the top rim fixed in position by
the points.
The Clay having been cut roughly to the required size and thickness is placed.in
or on the top frame and the pressure having been adjusted it is passed under the
Scraper or Cylinder once or twice, using the screw-at-the-top-for-increased-
pressure.
If it is found necessary a tympanum of Leather, Cloth or Metal may be used.
If the Relief is very high a ram of wood or Metal may be used, made somewhat
to the shape of the ornament to be pressed out of the lower mould and fitted on to
the top frame after the Clay is on by means of points as in the lower mould.
The top rim is now withdrawn and a Plaster of Paris bat laid on the top of the
Clay Slab or Tile &c The mould and plaster bat turned over and the mould lifted
off the Clay Slab or Tile &c and returned to the bed of the Press.

Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1st using a Press of the construction of the Common Lithographic Press with the
addition of a Cylinder in the place of the Scraper if necessary and with a coil of
gas jets under the bed of the press to keep the Mould dry if required.
2ndly The bottom mould is to be made of Plaster of Paris or Metal cast into an
iron rim The rim of the bottom mould has raised or sunk points by which a top rim
can be perfectly adjusted The top rim is of the thickness required for the Slab,
Tile, &c and its sides are slightly beveled so that it may be easily lifted off the

page_text: pressed Slab, Tile &c.
The top rim may also have a number of cutters arranged as
intersecting bars so as to form a number of small tiles at once.
3rdly If the Relief is very high a ram of Wood or Metal may be used, made
somewhat to the shape of the ornament to be pressed out of the lower mould and
fitted on to the top frame by means of points.
