A communication by GUSTAV KREBS, of 4 Wörmlitzer Strasse, Halle-on-Saale,
in the Empire of Germany, Machine Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E. of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster, 118 New Street, Birmingham
in the County of Warwick, and 31 High Holborn in the County of Middlesex,
Civil Engineer, 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 has for its object a press for making pressed tiles and the like
which is characterised by the press stamp being formed of separate adjustable
plates.
On the accompanying drawings,
Figure 1 is a side view of the press partly in section;
Figure 2, a cross section of Figure i on the line a―b;
Figure 3, a plan view of Figure 1 partially in section ;
Figures 4 to 6 show the mode of action of the press stamp.
The constructive arrangement is as follows:-
The stand 1 which is provided with a table 2 carries on its upper end a frame-
work 3 in which a shaft 6 having a flywheel 4 and two cogwheels 5 is mounted.
Further, at each of the longitudinal sides of the framework 3, a rack 7 is movably
arranged, which racks are connected by means of bolts 8 to a rectangular frame
and engage with the cogwheels 5. On each of the inner longitudinal sides of the
framework is a rail 9 movably arranged and connected or engaging with the
bolts 8, which rail is connected with a sloping guide rail 10 forming an inclined
plane. In the interior of the framework, which is formed of a box, plates 12
having recesses, grooves or the like 11 are arranged, said plates being vertically

manner the plates are carried by the guide rails and may be suitably adjusted
vertically, one after the other corresponding to the slope of the rails. Thus the
press stamp is divided into several plates independent of each other but coming into
action one after the other, which in their turn are alternately supported on the
framework 3. As may be seen from the cross section in Figure 2, a moulding
frame 13 is adjustably arranged on the frame 1 and on the table 2 and is intended
for receiving the moulds and the material which is to be pressed. It may be
pushed under the framework 3 that is to say under the press stamp consisting of
plates as shown in Figure 3. Further, the press is provided with an ejecting
device 14 constructed in the ordinary manner and operated by means of a
treadle 15.
The mode of working of this improved press is as follows:-
The matrix frame 13 is drawn under the framework and pushed on to the table 2.
The moulds are placed in the same and the material, for instance, cement is inserted.
After the superfluous material has been scraped off, the mould frame is pushed
under the framework as is apparent from the position of the frame on the left hand
side of Figure 3. When this has been done, the flywheel 4 is revolved so that the
frame formed of the racks 7 is moved together with the guide rails 10 (Figure 4)

page_text: in the direction of the arrow 16. As long as the inclined plane of the guide rails 10
does not reach the sliding plates 12, the latter remain in the position shown in
Figure 4, and the loose mass of tile material 17 remains uncompressed. If the
guide rails 10 move further in the direction of the arrow 16, the pushing of the
separate plates 12 downwards and successively takes place as shown in Figure 5.
The loose tile material is then pressed in small successive compartments or divisions
so that a homogeneous plate is produced and the superfluous material is simul-
taneously divided or pushed away. If the guide rails 10 move further down into
the furthest position of the direction shown by arrow 16, the plates 12 assume the
position shown in Figure 6, that is to say, the tile mass 17 is fully compressed. If
from then the flywheel 4 be revolved in the opposite direction, an adjustment of the
guide rails 10 takes place in the direction of the arrow 18, by which means the
plates 12 are raised one after the other and returned to the position shown in
Figure 4, so that the matrix frame 13 with the finished pressed tile can be easily
withdrawn. The tile is pushed out with the ejecting mechanism 14 from the
moulding frame.
The dividing of the press frame has for its object to produce an even distribution
of the material which is to be pressed in the case of roofing tiles with an unequally
thick shape and to produce a homogeneous product.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. An improved press for use in making tiles and the like characterised by the
press stamp being composed of several plates movable successively against the
material to be pressed, for the purpose of producing an even distribution of
the same by the sub-divided and successive pressing of the material, and of
producing a homogeneous product, substantially as set forth.
2. In a press of the kind described, a pressing stamp formed of separate vertically
movable plates which are provided with grooves or recesses and moved successively
vertically by means of horizontally movable guide rails for the purpose set
forth.
