PROVISIONAL SPECIFICATION
Improvement in the Machinery used in the Manufacture of Tiles,
Quarries, and Bricks.
We, JAMES ELIJAH BRINDLEY, of 89 and 91, Bryan Street, Hanley, in the
County of Stafford, Manufacturer, and FRANK ROWLEY, of Whaley Bridge, in
the County of Derbyshire, Manager, do hereby declare the nature of this inven-
tion to be as follows:-
Our invention has reference to an improved construction of that part of the
machinery used in the manufacture of tiles, quarries, and bricks, which forms
the receptacle or mould for the clay during the act of consolidation by the
box."
press, and which receptacle is known as the
The "box" is a metal mould or collar made to the exact shape and size neces-
sary for the formation of the tile quarry or brick and forms the receptacle for
the clay while receiving the pressure necessary to consolidate the same and
which pressure is given by the descent of a top die or plunger sliding down
accurately within the box. It is found that the abrasive action of the clay on
the sides of the box quickly wears it away and to such an extent that after the
box has been in use for a time the tile made in it is of larger size and this
necessitates the frequent reconstruction of the box to bring it to its original
dimensions.
Our invention consists in making the inner sides of the box of separate plates
of glass, porcelain or stone, which by their superior hardness will better resist
the wearing action of the clay and so allow the box to be used a much longer
time without reconstruction.
The construction is as follows.
The box consists of an outer case of cast iron, rectangular in form, and of a
size which will allow a space of about an inch between its inner surface and the
outer surface of the plates forming the glass lining, the sides of the casing will
be about half an inch thick, and tabs or projections will be made on the same
to allow it to be screwed down in position in the tile press. It must be planed
true on its upper and under sides and made exactly the same height as the
glass, porcelain or other plates which, form the lining.
Using the ordinary top or bottom "plunger " of a tile press as a form or
pattern to construct upon, we take four oblong plates of glass, porcelain, or other
material and place them accurately against the sides of the plunger," while
in this position they are cemented, or otherwise securely fastened together.
This inner formation or glass lining is then removed from the plunger and
placed within the iron case and the space between the lining and the outer case
is filled with. "Portland" or other suitable cement.
When the cement has set firm the box is ready for use.
We do not tie ourselves to the use of glass porcelain, or stone as the material

suitable for the purpose.
Improvement in the Machinery used in the Manufacture of Tiles,
Quarries, and Bricks.
We, JAMES ELIJAHI BRINDLEY, of 89 & 91, Bryan Street, Hanley, in the
County of Stafford, Manufacturer, and FRANK ROWLEY, of Fernilee, Whaley
Bridge, in the County of Derby, Manager, 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:-
Our invention has reference to an improved construction of that part of the
machinery used in the manufacture of tiles, quarries, and bricks which forms
the receptacle or mould for the clay during the act of consolidation by the
press, and which receptacle is known as the "box."
The "box" is a metal mould or collar made to the exact shape and size neces-
sary for the formation of the tile, quarry or brick and forms the receptacle for
the clay while receiving the pressure necessary to consolidate the same and
which pressure is given by the descent of a top die or plunger sliding down
accurately within the box. It is found that the abrasive action of the clay on
the sides of the box quickly wears it away, and to such an extent that after the
box has been in use for a time the tile made in it is of larger size and this
necessitates the frequent reconstruction of the box to bring it to its original
dimensions.
Our invention consists in making the inner sides of the box of separate plates
of glass, porcelain stone, or steel which by their superior hardness will
better resist the wearing action of the clay and so allow the box to be used a
much longer time without reconstruction.
Our invention is illustrated in the accompanying drawings, in which:
Fig. 1, is a plan of the box.
Fig. 2, is a section of the same (at the line a-b).
In each drawing A, represents the iron casing B, the glass, porcelain, or
steel plates, C, the cement which secures the plates in position and beds the same.
The box consists of an outer case of cast iron rectangular in form, and of a
size which will allow a space of about an inch between its inner surface, and the
outer surface of the plates forming the lining, the sides of the casting will
be about half an inch thick and tabs or projections will be made on the same
to allow it to be screwed down in position in the tile press. It must be planed
true on its upper and under sides and made exactly the same height as the
glass porcelain stone, steel or other plates which form the lining.
The method of construction is as follows.
Using the ordinary top and bottom plunger of a tile press as a form or
pattern to construct upon we take the four oblong plates which are to form
the lining and place them accurately against the sides of the plunger, while in
this position they are cemented or otherwise securely fastened together. This
inner formation or lining is then removed from the plunger and placed within
the iron case and the space between the lining and the outer case is filled with
Portland, or other suitable cement.

page_text: When the cement has set the box is ready for use.
To secure the lining from moving from its position, indentations may be made
on the back of the plates to form a holdfast for the cement, or projections may
be cemented thereon for the same purpose.
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:-
1. The construction of that part of the machinery used in the manufacture of
tiles, quarries and bricks which is known as the box with a wear-resisting lining
substantially as herein shewn and described.
2. In the construction of the before mentioned box the use of an interior
lining of glass porcelain, stone, steel, iron or such other material as may be.
found suitable for the purpose, substantially as herein shewn and described.
3. The use of Portland or other suitable cement for the purpose of firmly
fixing the plates in the position required, and which cement completely filling
the whole space between the plates and the iron casing forms a perfect bed
for the plates, and thus affords the necessary support to enable them to stand
the pressure, substantially as herein shewn and described.
