PROVISIONAL SPECIFICATION.
Improvements in Clay Presses for Making Tiles and the like.
1, CHARLES HUELSER of the firm of Huelser & Co. of Temple Chambers,
London, International Patent Agency, do hereby declare the nature of this inven-
tion, a communication to me from abroad by Eduard Fröhlich Senior of Schwerin,
in the Empire of Germany, Manufacturer, to be as follows:-
The object of this invention is a device for forming in a very short time tiles
and similar objects by means of clay presses, which is in the main constructed as
follows:
A suitably sized mouth piece secured by means of slotted pegs or projections to
the discharge opening of the day press has at the bottom an upward outer bend and
at the top a hinged screw bolt. Into the said bend is placed a corresponding
projection or bar of the mould box, the upper rim of which is clamped fast by means
of a lever nut provided on the hinged bolt. Prior to securing the mould box in
the described manner to the mouth piece, mitre-fashion adjoining core pieces are
introduced into said box. Through outwardly extending apertures, gypsum, sulphur
or other suitable substance is cast into the spaces left by the core pieces for the
purpose of ensuring a tighter fit.
In the middle of the mould box an opening is provided, through which is shifted
a catch by means of which the stencil is fastened.
On the clay press being operated, the plastic clay is pressed into the space
between the core pieces and the stencil, while the air is allowed to escape through
slits provided in the mould box.
When the clay commences to come out through said slits, the lever nut mentioned
above is loosened and a wire is passed along the rear surface of the mould box
whereby the tile or other object is formed which can be taken out after loosening
the stencil and removing the core pieces.

Improvements in Clay Presses for Making Tiles and the like.
1, CHARLES HUELSER of the firm of Huelser & Co. of Temple Chambers,
London, International Patent Agency, do hereby declare the nature of this inven-
tion, a communication to me from abroad by Eduard Fröhlich Senior of Schwerin,
in the Empire of Germany, Manufacturer, 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 a device for forming in a very short time tiles and
similar objects by means of clay presses.
Referring to the accompanying drawing,
Fig. 1 is a vertical longitudinal section, Fig. 2 a front view Fig. 3 a plan of the
improved device.
Figs. 4 and 5 illustrate a detail.
To the discharge opening of the clay press is secured by means of slotted pro-
jections the mouth piece A. having at the bottom a bend a and at the top a
hinged screw bolt k. Into bend a is introduced the bar a' of the mould box B, the
upper rim of which is clamped fast by means of a lever nut provided on bolt k.

Prior to securing the mould box in the described manner to the mouth piece A,
mitre-fashion adjoining pieces D are introduced into said box. Through the
apertures gypsum, sulphur or other suitable substance is cast into the spaces left
by the core pieces for the purpose of ensuring a tighter fit.
d
The mould box B has in the middle an opening, through which the catch e is
shifted, by means of which the stencil C is fastened.
When the clay press is operated, the plastic clay is pressed into the interstice
between the core pieces D and the stencil C, while the air is allowed to escape
through the slits of the mould box.
When the clay commences to come out through the slits i, the nut is loosened
and a wire is passed along the rear surface of the mould box B, whereby the tile O
is formed, which can be removed after loosening the stencil C and taking out the
core pieces D.
In order to allow the clay press to be incessantly used, a certain number of mould
boxes provided with stencils and core pieces are always kept ready.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
A device in clay presses for forming tiles and similar objects characterised by
the mould box B secured to the mouth piece of the clay press, said box being
provided with core pieces D joined mitre-fashion, a stencil C adapted to be taken
out and slits for allowing the air to escape, substantially as set forth.
