Improvements in Machinery for Manufacturing Mosaic Tiles or
Plates for Floors, Walls, and the like.
I, RICHARD HESS, of Rathener Strasse, Dt. Lissa, Silesia in the German Empire,
Manager, 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 improvements in machinery for manufacturing mosaic tiles
and plates, and the object of the invention is to provide improved devices for filling
the divisions of the mould boxes employed to receive the various colours, in such
manner that no "packing" of the material can occur in the respective receptacles,
even when the material is damp, and that a steady and even delivery of the materials
is secured. The machinery heretofore in use for the purpose does not effect the
desired object with sufficient certainty, is of a complicated nature and therefore
expensive in construction and maintenance.
The essential feature of the present invention is the application of pestle or ramming
rods having paddle blades fixed thereto. These rods when moved up and down, have
imparted to them a rotatory motion, so that the material in the divisions of the mould
boxes is loosened throughout its whole depth in order to be regulated and conducted
uniformly to the outlet holes in the pattern plate. The pestle or ramming rods
operate simultaneously as loosening appliances, and as means of conveyance, without
the employment of springs or similar intermediate devices, which experience has
proved to be productive of inconvenience when employed.
In the accompanying sheet of drawings
Figure 1 is a sectional elevation of a machine with my invention applied thereto,
Figure 2 is an end view of sanie,
Figure 3 is a view to a larger scale of one of the rotating pestle or ramming rods
provided with paddle blades,
Figure 4 is a plan of a part of the guiding device employed in connection with
the rotation of the pestle or ramming rods driving their up and down movements.
a is the bed-plate of the machine, with which are connected the columns a¹ which
support the head plate a 2. On the plate a 2, is placed the shaft a 3 adapted to rotate
in suitable bearings and carrying the eccentrics a 4. This shaft may be driven by a
crank handle or otherwise and its eccentrics effect, by means of the connecting rods b,
the up and down movements of a plate c guided on the columns a', by means of
suitable guide sockets or sleeves. To the under side of this plate care secured guiding
columns d, the cylindrical prolongations d' of which engage in corresponding guide
sockets which are secured to the frame for to the pattern plate g. To the plate o
are also secured the rods h, by means of which the pestle or ramming rodsk which
serve to loosen the material in the divisions of the material box i formed by the
separating partitions j, are operated. These rods k are secured to lifting plates by
means of screw nuts as shown clearly in Figure 3. The rods h connected to the
plates c also engage with the lifting plates so that, when the plate c is moved
upwards and downwards the pestle or ramming rods k are moved up and down also.
In order to effect the rotating of the rods k, which are provided with the paddle
blades k', during their up and down motion, they are furnished at their upper parts
with screw threads or worms which move in corresponding internally screw-threaded
holes in the bars m which are firmly secured to the box or case i.

page_text: The lower end of each rod k is furnished with a head the size of which corre
sponds nearly to that of the perforations in the pattern plate g, through which the
material is to be delivered. To the head is fastened a plate or pin which keeps
the hole in the pattern plate g in which it works free for the passage through the said
hole of the material. When the crank shaft a³ is rotated the plate c with the rods h
of the lifting plates 7 and the pestle or ramming rods are moved up and down
causing the rods k to rotate, and, by means of their paddle blades , to effect a
thorough loosening of the material throughout the whole depth of the divisions of
the material box i so that a regular and even passage of the material through the
perforations in the pattern plate g is effected.
The box i, the pattern plate g, its frame f, and the guiding sockets or sleeves e
for the rods d remain normally stationary, but when these parts are to be moved
along with the plate c by means of the crank shaft a³, coupling hooks n are applied,
which are pivotted to d, and are adapted to engage with studs el on the guide
sockets e. These hooks can be supported out of action by pivotted cross bars o,
see the left hand side of Figure 1.
The bed-plate a carries the press mould p, which receives the matrix 9 and the
frame in the usual way; the pattern plate g fits into the framer and the latter
encloses the template or stencil plate which can be changed to suit the pattern of
the tile or plate to be produced. The perforation of the pattern plate g, the sub-
division of the material box i, and the arrangement of the pestle or ramming rods k
with their appurtenances are of course varied according to the different patterns of
tiles or plates to be produced. For the purpose of effecting an accurate adjustment
of the press mould q, guiding sockets for bolts & are provided on the bed a.
bolts s are connected together by means of a cross head t and they can be raised in
opposition to the action of springs v by means of a lever u, in order to place the
press mould firmly in the correct position.
These
When the press mould is filled with the polychrome material, the coupling hooks n
are hooked to el, see the right hand side of Figure 1, so that the lower part of the
machine with the pattern plate g can be raised up by a half-turn of the crank shaft a³,
and the press mould p is thus left free for the removal or insertion of the matrix.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
First. In a machine for manufacturing mosaic tiles or plates the mechanism f
securing the regular and even filling of the divisions of the mould boxes with th.
polychrome material for thoroughly loosening the said material, and for assuring
regular delivery thereof through the perforations in the pattern plate 9, which coL
sists of the pestle or ramming rods k provided with paddle blades k¹ and moved u
and down, and rotated in the several divisions of the said boxes, substantially a
described.
Second. In a machine of the kind herein described for manufacturing mosaic tile
or plates, the use of coupling hooks n adapted to he put into or out of action
pleasure to allow of the connection of the upper part of the machine, (which alon
is moved when the press mould is being filled) with, or its disconnection frot
that part of the machine which remains stationary during the operation of fillin
and which carries the pattern plate, substantially as and for the purpose described.
