Improvements in Apparatus for Moulding Tiles.
We, ABRAHAM WEIL, of 291 Hoxterstiasse, and WILHELM PRASSE, of
Bahnhofstrasse, both of Steinheim, Westphalia, in the Empue of Germany,
Merchants, do hereby declare the nature of this invention and in what manner the
3ame 18 to be performed to be particularly described and ascertained in and by
the following statement.―
This invention relates to that class of apparatus for moulding tiles in which the
cement or the like is fed from a hopper onto a suitable table or mould, and the
essential feature of thus improved apparatus is that a sheet-plate-mould of suitable
shape is provided for recoiving the cement or the like, and is so arranged as to be
capable of being taken out with the moulded tile therein.
This apparatus is shown in the aunexed drawing in which
Fig. 1 epresents a longitudinal section.
Fig. 2 a plan view of the press
Fig. 3 a longitudinal section of the upper part of the press on a larger scale.
Fig 4 shows the sheet-plate-mould in perspective view
The constructive arrangement will be understood from the following description.
The one part of the mould-plate is aanged so as to form a floor or backing J,
which is suitounded by a frame e. Within the floor f a knock-out device is
guided by means of which the moulded tiles are lifted out. Inside the frame e
and upon the floor a sheet-plate-mould is placed, which can be easily taken out
with the knock-out device. For the purpose of forming the fixing or hanging
ledge on the underside of the tile, this sheet metal receptacle is provided with a
rectangularly bent portion and for forming the downwardly overlapping edges on
the underside it is likewise provided with the rectangularly bent portions k.
For the purpose of producing ribs or any projecting shapes in general the sheet-
mould is provided with corresponding impressions 1.
The method of operating the apparatus thus improved will be understood from
the following
-
The sheet-metal-mould is placed upon its backing or floor, a charge of cement
placed upon the plate and rubbed down flat thus forming a cement pantile, with
the exception of the upper hooking ledge. After this is done, the upper ledge-
forming-at rangement c is brought forward over the flattened cement pantile, and
the upwardly projecting ledge is produced in the ordinary way. When the tile 18
thus completely moulded, the upper ledge-forming-arrangement a is pushed back
again into the position shown in Fig. 1, then the tieadle-lover m 18 pressed down
by the foot and the sheet-mould with the moulded tile is thus lifted out of the
framing e.
The tiles thus formed resting on their sheet-metal-mould plates are taken from
the press and dried or otherwise finished and when the latter process is completed,
the tile is removed from the plate and the plate is ready to be used again.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim 18
1. In apparatus for moulding cement or other tiles, the combination with a
suitable support of a removable sheet-metal under mould or plate / seiving also as
& support or basis for the tile during operations subsequent to the moulding
substantially os set forth.

bent portions ik and with suitable impressions 1, substantially as described and for
the purposes set forth.
