I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Chartered Patent Agent, do hereby declare the nature
of this invention to be as follows:-
-
This invention relates to apparatus for simultaneously and uniformly introducing
powdered colouring matters into the compartments of moulding boxes for the
manufacture of pressed bricks bearing designs.
The apparatus consists of a box for the storage of the colouring matters provided
with a removable bottom which is formed with a number of grouped apertures
corresponding to the design to be produced on the pressed bricks to be manu-
factured.
The colouring matter storage box has a number of compartments for the recep-
tion of substances of different colours, and in which there are inserted wires
which are studded with metal or hair bristles or rods that may consist of helically
coiled strips of sheet metal or of peculiarly bent perforated, or not perforated,
sheet metal strips, and which may be provided at their lower ends also with
metal or hair bristles.
The wires or rods so constructed are adapted to be shaken up and down by
means of a lever arranged at the top of the apparatus and provided with a handle.
By means of these. peculiarly shaped wire rods and sheet metal strips, the colour-
ing matters are kept in constant movement, so that clogging or caking thereof
is rendered impossible and a uniform downward feed of the materials is effected
with certainty.
In the upward movement of the hand lever the brushlike bristles allow the
colouring matters to pass through the perforated bottom into the mould template
or pattern. When the lever is moved down, the bristles at the bottom spread out
and close the apertures in the bottom against the following material. The more
frequently this shaking or up and down movement takes place, the greater will
be the quantity of colouring material in the mould template or pattern. When
the same is filled, the upper part of the apparatus, which rests on a frame, is
raised by means of lever mechanism and the mould box situated below the same
is drawn out and quite filled with material for the further completion of the
pressed brick-stone, and then placed under the press after the design template
has been lifted out. The lever mechanism, which is arranged in a box forming
the base of the apparatus, consists of lever rods arranged at both ends of the
apparatus, and of which the vertical rods are keyed fast on axles that are pivotted
in the box and can be moved by means of a hand lever or treadle lever. Upon
the central horizontally-arranged lever rods, there rest two pairs of cheeks

page_text: which are guided in suitable slots of the box. By suitably operating the hand lever
or the treadle lever cheeks are either raised or lowered, and thereby produce the
raising or lowering of the entire charging apparatus.
In another arrangement the box for the storage of the colouring material is made
of sheet metal instead of wood, and some inlet channels for the colouring matter
are arranged in the compartments of the storage box.
An essential feature consists in studding the wires with peculiarly formed
brushes in their length as also at their lower ends. The wires being studded in
their length with radially projecting brushes which may be arranged in the form
of a pyramid that is to say, the brushes having the same diameter throughout.
In both cases, there is provided sufficient space between the several brushes for the
accommodation of colouring matters, which matters are continually loosened by the
movement of the brushes and thereby constantly sink downwards.
The wires are provided at their lower ends with brushes which have also radially
projecting bristles that close the holes in the pattern plate when the wires descend,
whilst in the ascending movement, they allow the colouring matters to pass
through the bristles and enter the patterns.

Improvements in the Manufacture of Bricks and Tiles.
A communication from abroad by the BERLINER KUNSTDRUCK AND VERLAG-
SANSTALT, vormals A. AND C. KAUFMANN, Berlin, Germany.
I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Chartered Patent Agent, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to apparatus for simultaneously and uniformly intro-
ducing powdered colouring matters into the compartments of moulding boxes for
the manufacture of pressed bricks bearing designs.
Figs. 1 and 2 of the accompanying drawings are respectively a side elevation,
partly in section, and a sectional end elevation of apparatus according thereto. The
apparatus shown in Figs. 1 and 2 comprises a box 1 for the storage of the
colouring matters, which is provided with a removable bottom 2 formed with
a number of apertures 3 grouped correspondingly to the design to be produced on
the pressed bricks to be manufactured.
The colouring matter storage box 1 has a number of compartments 4, which
are intended for the reception of substances of different colours and in which there
are inserted wires 5 which are studded with metal or hair bristles, or rods 6 which
may consist of helically coiled strips of sheet metal or of peculiarly bent and
perforate, or imperforate sheet metal strips; the wires 5 or the rods G may also be
provided at their lower ends with metal or hair bristles 7.
The wires 5 or rods G so constructed are adapted to be shaken up and down
by means of a lever 8 arranged at the top of the apparatus and provided with a
handle. By means of these peculiarly shaped wire rods and sheet metal strips,
the colouring matters are kept in constant movement, so that clogging or caking

page_text: thereof is rendered impossible and a uniform downward feed of the materials is
effected with certainty.
In the upward movement of the hand lever S the brush like bristles allow the
colouring matters to pass through the perforated bottom 2 into the mould tem-
plate or pattern. When the lever 8 is moved down, the bristles 7 spread out and
close the apertures 3 in the bottom 2 against the following material.
The more frequently this shaking or up and down movement takes place, the
greater becomes the quantity of colouring material in the mould template or
pattern 9. When the same is filled, the upper part of the apparatus, which rests
on a frame 10, is raised by means of lever mechanism 11, 12, 13, and the mould
box 14 situated below the frame 10 is drawn out, whereupon the mould box is
entirely filled with material for the further completion of the pressed brick or
tile, and placed under the press after the design template 9 has been lifted out.
The lever mechanism, which is arranged in a box 15 forming the base of the
apparatus, comprises rods 11, 12, and 13 which are arranged at both ends of the
apparatus and of which the vertical rods 11 and 13 are keyed fast on axles 16
which are mounted in the box 15 and can be moved by means of a hand (or
treadle) lever 17. Upon the central and horizontally arranged rods 12 there rest
two pairs of cheeks 18 and 19, which are guided in suitable slots 20 in the box 15.
By suitably operating the hand (or treadle) lever 17, cheeks 18 and 19 are either
raised or lowered, and thereby produce the raising or lowering of the entire
charging apparatus.
Figs. 3 and 4 are views corresponding to Figs. 1 and 2 of apparatus similar to
that shown in the latter two figures but having its box 1 for the storage of the
colouring material made of sheet metal instead of wood, and being provided with
funnels 21 for leading the colouring matter into the compartments 4 of the
storage box 1. The characteristic feature of the apparatus shown in Figs. 3 and 4,
however, consists in the studding of the wires 5 with peculiarly formed brushes
in the direction of their length as well as at their lower ends. As shown in
Fig. 3, the wires are studded in the direction of their length with radially projecting
brushes 22. The brushes may be arranged to decrease in diameter in an upward
direction, so that they assume the form of a pyramid, as shown in Fig. 5; or
they may be arranged in cylindrical form the brushes having the same diameter
throughout as shown in Fig. 6 In both cases, sufficient space is provided between
the several brushes for the accumulation of colouring matters, which are con-
tinually loosened by the movement of the brushes and are thereby caused con-
stantly to sink downwards. The wires are provided at their lower ends with
brushes 2 which have also radially projecting bristles that close the holes 3 in
the pattern plate 2 when the wires 5 descend, whilst during the ascending move-
ment, they allow the colouring matters to pass through the bristles and enter the
template or pattern 9. The arrangement of brushes shown in Figs. 3, 5, and 6
have given very satisfactory results as regards the loosening of the colouring
matters and their regular delivery to the patterns. Figs. 7, 8, and 9 illustrate
some designs that can be produced by means of the apparatus herein described.
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
1. Apparatus for simultaneously and uniformly introducing powdered colouring
matters into the compartments of moulding boxes for the manufacture of pressed
bricks or tiles bearing designs, in which the holes which are grouped in the bottom
plate of the storage box correspondingly to the design, are closed or opened by
means of numerous, simultaneously operated, and suitably shaped wires, rods, or
sheet metal strips 5 or 6, which are studded at their ends with brush-shaped
bristles, which, during their upward and downward movement, allow fresh
colouring material to pass around them and in between the bristles.
2. Apparatus according to the preceding claim, in which the wires are provided

page_text: in the direction of their length with radially projecting brushes in pyramidal or
cylindrical form and at their ends with radially arranged brushes that close or
open the holes in the pattern plate.
3. Apparatus for simultaneously and uniformly introducing powdered colouring
matters into the compartments of moulding boxes for the manufacture of pressed
bricks or tiles bearing designs, constructed, arranged, and operating as herein-
before described with reference to and shown respectively in Figs. 1 and 2 and
in Figs. 3 and 4 of the accompanying drawings, whether, in the latter case the
wires 5 be provided with brushes as shown in Figs. 5 or as shown in Fig. 6.
