COMPLETE SPECIFICATION.
Improved Mould for Manufacturing Tiles.
I, JULIUS THEODOR KÖHLER, of the Firm of Theodor Köhler, of Bahnhof-
strasse 12, Limbach, Saxony in the Empire of Germany, Merchant 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 a press by means of which the known form of tile shown
in Fig. I in the annexed drawing can be produced.
The characteristic feature of this press consists in a device, which allows of
producing the fold a on the upper sides of these tiles, of an exactly equal height and
of perfect quality.
As Fig. 2 shows, the press consists in the known manner of a frame 1, on the
correspondingly perforated table of which is fixed the form frame 2 which in
horizontal section has the form of the tile to be produced, and through which
frame pass the bolts 4 of the lifter 3 for the purpose of raising the finished tile
out of the form.
The bolts 4 press for this purpose on a movable bottom 21 of the frame, the
upper side of which is shaped in accordance with the under side of the tile.
The up and down movement of the lifter 3 is effected by means of the rod 5 and
the pedal lever 6.
On the moulding frame 2 are further fixed two frames 8 and 9 by means of a
hinge joint 7 in such a manner, that they lie the one 9 on the other 8 so that they
can be turned down upon the upper edge of the moulding frame 2 or turned up
therefrom as in Fig. 2.
On the upper side of the frame 8 is displaceably mounted a slide 10, (Fig. 3)
which is guided in guides 8¹ on the frame 8, as well as by means of its slots 101 on
screws 11 screwed into the frame 8.
This slide 10 can be moved in the direction of the arrow I (Fig. 3) in such a
manner upon the frame, that it will cover a slot 12 provided in the frame.
The slot 12 corresponds in its position and form with the fold a to be formed on
the upper side of the tile Fig. 1.
The frame 9 has a similarly shaped border 13, on its under side in such a
manner that, when the frames 8 and 9 lying over one another are turned down
upon the moulding frame 2, this border penetrates to a certain distance into the
slot 12.
This penetration is determined by a projection 9¹ provided on the border 9 which
serves simultaneously, as well as the pieces 8" of the frame 8 as handles for turning
the frame back.
The use of this device is illustrated by Figs. to 8, which show the apparatus in
longitudinal section in its characteristic working positions.
The moulding frame 2 is opened, that, is to say the frames 8 and 9 are moved
back into the position shown in Fig. 2 or 4 and the frame 2 is filled up to its
upper border with the tile material (loam, clay etc.) which is well stamped or beaten
in and then wiped off evenly.
Then the frame 8 with the opened slide 10 is turned down upon the moulding
frame 2, Fig. 5, the slot 12 is filled with the material and the slide 10 is pulled

page_text: forwards by its handle 10" so that it slides over the slot 12 and cuts the superfluous
material smoothly off (Fig. 6).
A tile is thus produced of the form shown in Fig. 1 lying in the moulding form,
the folds a of which tile are exact in height, and straight in form.
In order to take this tile out without distorting it or injuring the fold a when
turning the frame 8 upwards, there is provided the frame 9.
This frame is now turned down, so that it lies with its border 13 upon the fold a,
Fig. 7 and the projection 9 are firmly pressed down with the piece 811 together thus
raising slowly the frame 8.
Consequently the border 13 in accordance with the lifting of the frame 8 moves
the fold a of the tile slowly and without injuring it out of the slot 12, whereupon
both frames 8 and 9 can be turned back completely from the moulding frame.
A pressure upon the pedal 6 lifts the bottom plate 8' with the finished tile out of
the moulding frame 2 Fig. 8, aud the tile can be carried away in the plate to be
baked or otherwise.
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 :-
1. A tile press having a frame 8 hinged upon the moulding frame 2 and provided
with a slot 12 and a slide 10 and serving for forming the fold a by means of the
said slot and by pulling the slide 10 forwards.
2. A press as described in Claim 1 in which a second frame 9 with a border 13
can be turned over the frame 8 in such a manner, that the border 13, extends into
the slot 12 and rests upon the fold a of the tile lying in the form and presses this
fold during the back movement of both frames 8 and 9 slowly and equally out of
the slot 12 for the purpose of preventing the fold from being injured whilst opening
the form.
