Improvements in Facing-bricks or Tiles.
I, WALTER JOHN, of the firm of Hoffman, John & Co., the Münchhof
Porcelain and Fire Proof Ware Factory, Münchhof, near Carlsbad, in the Empire
'of Austria do hereby declare the nature of this invention to be as follows:-
My invention relates to facing-bricks or tiles of porcelain or pottery ware.. Such
bricks or tiles as hitherto employed for the purpose of facing and coating walls,
bathrooms and the like have been made in the form of plates. Their back surface,
which if rough is yet level, affords a very slight hold to the layer of mortar or
cement, and the joints which are generally visible at the front, especially in facings
'arranged in patterns, break the continuity of the figures shewn upon the bricks or
tiles
By the use of facing-bricks or tiles made according to my invention, wall
coverings can be so put together that no mortar or cement. joints are visible
externally, and the individual bricks or tiles are united with the plaster upon the
wall with a firmness which has hitherto been unattainable.
In carrying out my invention instead of making the facing bricks or tiles as
'heretofore in the form of regular plates, I make them hollow somewhat in the form
of tiles partially open at the back, their side faces being made oblique for the
purpose of affording a secure hold for the layer of mortar, plaster, or cement
between them. Or their front surfaces can be made to extend beyond the side
faces." Or such projecting front faces may be used in combination with oblique
'side faces: "

In the accompanying drawing,
Figure 1 is a perspective view of a facing brick or tile made according to my
invention with the front face projecting beyond the side faces.
Figures 2 and 3 are horizontal sections of my improved bricks or tiles, one being
shewn with a projecting front face and rectangular side faces and the other with a
non-projecting front face and with oblique side faces. The facing brick or tile as
shewn is made of the form of a hollow body of the shape of a tile, the back wall
of which is provided with an opening a. When the brick or tile is pressed on to
the coated wall, the mortar, plaster or cement, enters the inside of the facing brick
or tile through the opening a and fills it as the tile is firmly pressed against the
wall, so that the facing brick or tile adheres fast to the wall.

the purpose becomes pressed, so that the whole periphery of the facing tile.is.at

its back are surrounded by the coating.

the facing bricks to the wall to be covered is attained, and the joints are not

Improvements in Facing-bricks or Tiles.
I, WALTER JOHN, of the firm of Hoffman, John & Co., The Münchhof
Porcelain and Fire-proof Ware Factory, Münchhof near Carlsbad, in the Empire
of Austria, 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 :-
My invention relates to facing-bricks or tiles of porcelain or pottery ware.
Such bricks or tiles as hitherto employed for the purpose of facing and coating
walls, bathrooms and the like have been made in the form of plates. Their back
surface, which if rough is yet level, affords a very slight hold to the layer of mortar
or cement, and the joints which are generally visible at the front, especially in
facings arranged in patterus, break the continuity of the figures shewn upon the
bricks or tiles.
"
By the use of facing-bricks or tiles made according to my invention, wall
coverings can be so put together that no mortar or cement joints are visible
externally, and the individual bricks or tiles are united with the plaster, upon the
wall with a firmness which has hitherto been unattainable.

In carrying out my invention instead of making the facing-bricks or. tiles as
'heretofore in the form of regular plates, I make them hollow somewhat in the form
of tiles partially open at the back, their side faces being made oblique for the
purpose of affording a secure hold for the layer of mortar, plaster, or cement
between them. Or their front surfaces can be made to extend beyond the side
faces. Or such projecting front faces may be used in combination with oblique
side faces.

In the drawing accompanying the Provisional Specification
Figure is a perspective view of a facing-brick or tile made according to my
invention with the front face projecting beyond the side faces:
Figures 2 and 3 are horizontal sections of my improved bricks or tiles, one being
'shewn with a projecting front face and rectangular side faces and the other with a
non-projecting front face and with oblique side faces. The facing brick or tile as
'shewn is made of the form of a hollow body of the shape of a tile, the back wall of
which is provided with an opening a. When the brick or tile is pressed on to the
coated wall, the mortar, plaster or cement, enters the inside of the facing brick or
tile through the opening a and fills it as the tile is firmly pressed against the wall,
so that the facing-brick or tile adheres fast to the wall.
By means of the projections 6 (Figure 2) on the outer face of the brick or tile
or by means of the obliquity of its side faces c (Figure 3) hollow spaces are formed
between the bricks or tiles into which as the wall is coated the moist layer used
for the purpose becomes pressed, so that the whole periphery of the facing tile is
at one and the same time surrounded by the coating of the wall, and both surfaces
of its back are surrounded by the coating.
It will be obvious that by this arrangement, an extremely firm adhesion of the
facing-bricks to the wall to be covered is attained, and the joints are not visible.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A hollow facing-brick of porcelain or earthenware, the hinder face of which
is provided with a recess, for the purpose of affording to the material used for
coating the wall access to the interior of the brick, and the lateral surfaces of which
are inclined obliquely backwards, or the front surfaces of which project all round
beyond the lateral ones, whereby a space not visible from without is provided for

page_text: the material of the coating of the wall to be pressed into, essentially as described
and illustrated in the drawing.
2. The manufacture and use of the improved facing bricks or tiles hereinbefore
described and illustrated in the accompanying drawing.
