Figure 6, a perspective of a four inch wall or furnace lining constructed of my
improved brick.
Figure 7, a similar view of a nine inch wall.
Figure 8, a bottom plan view of a brick provided with transverse grooves for
use as headers and
Figure 9, a similar view of a brick provided with longitudinal grooves for use as
stringers as will hereinafter more fully appear.
Reference being had to the drawings and the letters thereon A indicates a brick
which may be called a universal bond brick, and is provided on one side with spurs
or projections a which are arranged in a plurality of pairs and are equidistant from
each other longitudinally and transversely on the brick; and the distance from
the ends and sides of the brick to the spurs is equal to one half the distance between
any two spurs, and on the other side of the brick and directly opposite the spurs a
are depressions 6 which correspond with the spurs and form seats with which the
spurs on an adjacent brick engage.
By spacing the spurs and depressions and arranging them in pairs as shown and
described, the brick may be placed one on top of another in any position required
in constructing a wall that shall be straight or at any right angle, as is shown in
Figure 6, and in constructing a nine inch or a thicker wall the stringers and headers
are securely bonded or tied together.
In Figures 3, 4, and 5, I have shown a modification of the construction shown
in Figures 1 and 2. In the latter construction one surface or side is provided with
longitudinal ribs or projections c and transverse ribs or projections d, which are at a
right angle to each other and intersect, and on the other side of the brick and
directly opposite the ribs c d are corresponding grooves or depressions e f: This
011

page_text: brick may be used where the appearance of the ribs and grooves will not be
objectionable.
To provide for repairing fire brick walls or linings for furnaces without tearing
down the wall or lining some of the bricks A are provided with transverse grooves
or depressions g which are directly opposite the spurs a and others with longitudinal
grooves h.
The application of these two forms of bricks is shown in Figure 7, in which a
heading course is shown with the grooves g and a stringer with the grooves h. By
applying these bricks in the manner shown new bricks may be inserted in any part
of a wall underneath the headers that require renewing without interfering with
parts of the wall above.
The spurs and depressions may be varied in number so long as they are preserved
in pairs arranged equidistant, thus there may be four, six, or eight, and in bricks
or blocks larger than the standard brick the number may be increased. Bricks
constructed as described are admirably adapted for constructing walls, the pro-
jections and depressions being of such height and depth as to allow the bricks to
lie close upon each other and to bind the brick so that lateral displacement of
bricks from a course is impossible.
When used in walls for buildings a thin layer of cement or mortar may be used
without interfering with the projections and depressions.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
First. An improved article of manufacture, a brick provided with projections
arranged equidistant and in a plurality of pairs on one side and corresponding
depressions in the opposite side.
Second. An improved article of manufacture, a brick provided with projections
arranged in a plurality of longitudinal and transverse equidistant pairs on one side
and corresponding depressions in the other side and opposite said depressions.
Third. A brick provided with a plurality of pairs of projections arranged equi-
distant longitudinally and transversely of the brick and on one side thereof, and
grooves in the opposite side of the brick.
