Improvements in Bricks, Tiles, and the like.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this inven-
tion (a communication to me from Félix Pagnon, of 22, Rue Tramassac, Lyons,
in the Republic of France, Engineer) to be as follows: -
The invention consists of a bonding or interfitting brick or tile of special
form, decorated on one of its faces or upon its two faces and capable of being
used without the use of plaster, cement, mortar and any other material tem-
pered with water, in the construction of partitions and other works it conse-
quently avoids the use of coatings of these materials covering the partitions
themselves and enables works thus constructed to be used immediately.
The accompanying drawing shows the arrangement of these new bricks or
tiles and the method of assembling them.
Fig. 1 represents a face view of three square bricks as placed together.
Fig. 2 shows to a larger scale a transverse section on the line 1-2 of Fig. 1.
Fig. 3 shows the application of the same-
e-interfitting or bonding means to
a brick of polygonal shape.
The square or rectangular brick shown in Fig. 1 has formed in two of its
adjacent sides, channels or grooves AA and upon the two other sides, tongues
or projections B, B, for the purpose of interfitting or bonding as seen in section
at Fig. 2.
The tongues or projections and the channels or grooves have somewhat the
same trapezoidal section but although the small base ab of the tongue fits
exactly the base of the channel or groove, its larger base leaves a certain
amount of play cc which facilitates the assembling. Further the small
faces ee which limit the visible faces of the brick, are inclined inwards thus
forming a small space which adjoins the space c.
The small base ab of the tongue or projection and the bottom of the channel
or groove, are each provided with a small semi-circular groove the junction of
which forms a cylindrical hollow d.
The objects of these forms are:-
1. In constructing partitions upon relatively narrow bases, to prevent the
irregularities which would result from imperfect contact of large surfaces and
to assure the junction of the visible faces of the bricks.
2. To superpose exactly these faces in the same plane by the exact adjust-
ment of the part ab in the bottom of the channel or groove.
3. To consolidate when desirable the whole wall and to render it water tight
by the introduction of a plastic material in the spaces cde without this material
showing upon the visible faces of the bricks.
These bricks may be assembled with their meeting edges in straight lines
or so as to break joint, their two faces may be polished, enamelled and decorated
in course of manufacture and remain bare after the construction of the walls
or they may be assembled and without any previous coating they may be

page_text: covered with thin boards or wall paper as desired. These bricks enable in
every case a rapid construction without any inconvenience and the immediate
use of the works to which they have been applied.

Improvements in Bricks, Tiles, and the like..
I, BENJAMIN JOSEPII BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this inven-
tion (a communication to me from Félix Pagnon, of 22, Rue Tramassac, Lyons,
in the Republic of France, Engineer), and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
The invention consists of a bonding or interfitting brick or tile of special
form, decorated on one of its faces or upon its two faces and capable of being
used without the use of plaster, cement, mortar and any other material tem-
pered with water, in the construction of partitions and other works, it conse-
quently obviates the use of coatings of these materials covering the partitions
themselves and enables works thus constructed to be used immediately.
The drawing accompanying the Provisional Specification shows the arrange-
ment of these new bricks or tiles and the method of assembling them.
Fig. 1 represents a face view of three square bricks as placed together.
Fig. 2 shows to a larger scale a transverse section on the line 1-2 of Fig. 1.
Fig. 3 shows the application of the same interfitting or bonding means to
a brick of polygonal shape.
The square or rectangular brick shown in Fig. 1 has formed in two of its
adjacent sides, channels or grooves AA and upon the two other sides, tongues
or projections B B for the purpose of interfitting or bonding as seen in section
at Fig. 2.
The tongues or projections and the channels or grooves have somewhat the
same trapezoidal section but although the small base ab of the tongue fits
exactly the base of the channel or groove, its larger base leaves a certain
amount of play ee which facilitates the assembling. Further the small
faces ce which limit the visible faces of the brick, are inclined inwards thus
forming a small space which adjoins the space c.
The small base ab of the tongue or projection and the bottom of the channel
or groove, are each provided with a small semi-circular groove the junction of
which forms a cylindrical space d.
The objects of these forms are:-
1. In constructing partitions upon relatively narrow bases, to prevent the
irregularities which would result from imperfect contact of large surfaces and
to assure the junction of the visible faces of the bricks.
2. To superpose exactly these faces in the same plane by the exact adjust-
ment of the part ab in the bottom of the channel or groove.
3. To consolidate when desirable the whole wall and to render it water tight
by the introduction of a plastic material in the spaces cde without this material
showing upon the visible faces of the bricks.
These bricks may be assembled with their meeting edges in straight lines
or so as to break joint, their two faces may be polished, enamelled and decorated
in course of manufacture and remain bare after the construction of the walls

page_text: or they may be simply smooth and without any previous coating they may be
covered with thin boards or wall paper as desired. These bricks enable in
every case a rapid construction without any inconvenience and the immediate
use of the works to which they have been applied.
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
1. A bonding brick or the like decorated upon one or both faces having upon
two adjacent edges channels or grooves of trapezoidal section and upon two
other edges tongues or projections of similar form, the small bases of which
fit the bottom of the channels or grooves of the adjoining bricks but leaving
on their other parts spaces for the purpose of facilitating the assembling and
receiving when desired a plastic material, substantially as herein shown and
described.
2. A bonding brick or the like formed with a trapezoidal tongue or projection
on one of its edges, the small base of which is of size to fit the bottom of a
trapezoidal channel or groove formed in an edge of another brick or the like,
the said small base and bottom of the channel each having a semi-circular
groove, and the sides of the trapezoidal tongue and channel being connected
to the outer faces of the brick by means of, short inclines, substantially as
herein shown and described.
3. A bonding brick or the like having a trapezoidal tongue or projection on
one of its edges with a groove along its small base and its large base connected
to the faces of the brick by means of short inclines, the small base of said
tongue being of size to fit the bottom of a channel formed on another of its
sides which channel is provided with a groove in its bottom and has its sides
connected to the outer faces of the brick by means of short inwardly inclined
faces, the tongue or projection on the one side having a smaller base than the
channel on the other side, substantially as set forth.
