PROVISIONAL SPECIFICATION.
Process and Apparatus for Producing Improved Faced Bricks.
I, FRANZ NAUMANN of Plottendorf, in the Empire of Germany, Manufacturer,
hereby declare the nature of this invention, to be as follows
--
do
This invention relates to bricks to be used generally for facing of buildings, such
facing bricks have generally hitherto been made wholly of one material. Since
however certain sides and generally one side only of such bricks is visible when built
as a facing, the purpose of this invention is to form a facing brick having one surface
of the facing material, the body of the brick being formed of inferior or ordinary
material.
-
For this purpose the brick press is arranged to separately receive and feed the two
materials to one outlet where they are so delivered as to form bricks having a more or
less thick layer of ordinary brick material and a more or less thin surface of the
facing material. The outlet of the brick press is formed of two superposed or parallel
openings divided by a nose plate which may be straight, corrugated or of other shape
to cause the two materials to be more intimately brought together at their surfaces of
contact.

I, FRANZ NAUMANN of Plottendorf, in the Empire of Germany, Manufacturer,
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 bricks to be used generally for facing of buildings; such
facing bricks have generally hitherto been made wholly of one material. Since
however certain sides and generally one side only of such bricks is visible when built
as a facing, the purpose of this invention is to form a facing brick having one surface
of the facing material, the body of the brick being formed of inferior or ordinary
material.
For this purpose the brick press is arranged to separately receive and feed the two
materials to one outlet, where they are so delivered as to form bricks having a more
or less thick layer of ordinary brick material and a more or less thin surface or surfaces
of the facing material. The outlet of the brick press is formed of two superposed or
parallel openings, divided by a nose plate which may be straight, corrugated, or of
other shape to cause the two materials to be more intimately brought together at their
surfaces of contact.
The accompanying drawings illustrate brick presses adapted for the manufacture of
the improved bricks.
Fig. 1 shows in vertical section a brick-press having separate hoppers a and b for
the reception of the clays or materials of which the body and surface respectively of
the brick are to be formed. Each hopper has its feed press A A, BB forcing the
respective materials to the openings de where they combine to issue from the
opening D, the material from e forming a layer of more or less thickness over one or
more sides of that coming from d according to the shape and arrangement of the
opening e with regard to the channel D.
Figs. 2 and 3 are cross sections on line M M Fig. 1 showing the press with one or
two openings respectively. The press shown in Fig. 4 differs only from that shown
in Fig. 1 in that the openings e and d are so arranged that the materials therefrom
enter the tube D simultaneously in their relative positions. The press shown in
Figs. 5, 6 and 7 is provided with parallel chambers, the hoppers aa for the two
materials being parallel side by side and divided by the wall E. The rollers A A are
also relatively arranged as shown and the wall E terminates in the edge / near in front
of the tube D. The chamber f of the facing material may be also in communication
with the tube D by the channel g' as shown."
h
The edge may be straight or corrugated or of any other suitable shape, whereby
the two materials are caused to unite more intimately on their surfaces of contact.
Hollow bricks may be made by arranging a core in the tube D.
I do not confine my invention to brick presses such as described, but may employ
any form of brick press.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1) As a new product of manufacture, a brick composed of an inner or under core
and an outer face or faces substantially as set forth.
2) In the manufacture of faced bricks as described, the combination with
tube D of two or more brick presses adapted to feed materials separately to the
said tube.
3) In the manufacture of faced bricks as described, the combination with
presses A A hoppers a a and tube D of wall E separating said hoppers and presses
and having edge has and for the purpose set forth.
Dated this 15th day of November 1887.
