Improvements in or relating to the Manufacture of Tiles, Slabs,
and the like.
I, CARL WICKE, Manufacturer, of Parallelstrasse 28, Lehe, in the Empire of
Germany, 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:-
―
The present invention relates to the manufacture of tiles, slabs and the like
from cement and other material. The apparatus is especially designed in order
that by its means roof tiles can be manufactured provided on the upper surface
with water-channels or grooves parallel to the sides and at a lower level than
the surface of the tiles, and which channels are formed in the tiles or slabs them-
selves.
In the accompanying drawing of a convenient form of the apparatus
Figure 1 is a vertical longitudinal section,
Figure 2 a cross section,
Figure 3 a side elevation,
Figure 4 a front view, and
Figure 5 a plan view.
Figures 6 and 7 represent parts of the machine, while
Figure 8 is a plan view,
Figure 9 an underside view, and
Figure 10 is a section through a tile.
On the moulding table a is arranged the mould plate f of strong resisting
material, corresponding in height and thickness to the tiles to be produced. Over
this mould plate a plate or frame c is pivotted or hinged at b so that it can be
placed on or removed from the former. This frame c is provided with two V
shaped slots and e, Figure 5. By the sides of the slot e are arranged two
knife-edges g slightly projecting at the bottom, which knives are pressed into
the moulding material, Figures 1, 2 and 6. By means of a scoop or knife k,
Figure 7, the cement or other material used for making the tiles is removed as
far and as deep as the knives g extend by which means the channels h Figure 8
on the upper side of the tiles are formed. The material thus removed through
the slote is placed in the adjoining slot d and then the plates / hinged at 2 on
the frame c, are turned down. These plates are provided with ledges m and n,
of which the ledge m which is much higher enters the slot e whereby the material
that had been rendered loose by the work of the knife is pressed down firmly.
The other ledge n presses down the material that had been placed in the slot d.
thereby forming the outer raised edge o (Figure 8). Below the table a is arranged
On this
a plate connected to a treadle levert and secured to a guide rod s.
plate are arranged four rods u which fit in corresponding holes in the mould
plate and are normally so arranged that their upper ends, together with that
of the rod s, are flush with the upper surface of the mould plate f. By means
of this device the finished plates can be raised from the mould after the frame c

page_text: has been swung back. The tiles are provided on the under surface with ledges
or ribs v corresponding to the channels and two intersecting grooves w into
which the raised edges o fit. The left side of the tile is provided with a dove-
tail shaped groove, while the right side is provided with a corresponding pro-
jection y which fit into each other when two tiles are placed in position, securing
a firm connection, the tiles otherwise being only hooked by means of projec-
tions (Figures 8 to 10) on their under surfaces to laths or the like.
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:-
1. Apparatus for use in the production of roof tiles and the like with pro-
jecting edges and water channels comprising a mould frame such as c, hinged
to a table carrying an under mould plate which frame is provided with slots
such as de for forming the projecting edges and water channels the inner slot
being provided at its under side with knives such as y in combination with two
plates hinged to the mould frame and having ribs or projections fitting into the
corresponding slots in the mould frame, substantially as described.
2. The complete apparatus for use in the manufacture of roof tiles and the
like substantially as described or illustrated in Figures 1 to 5 of the accompany-
ing drawing.
3. A roof tile substantially as described and illustrated in Figures 8, 9 and 10
of the accompanying drawing.
