Improvements in Bricks or Blocks for Building Purposes.
I, ERNST VON HÜNERSDORFF, of 52, Hagelbergerstrasse, Stuttgart, Wurtemberg,
Germany, Retired Lieutenant-Colonel in the Army of the King of Wurtemberg,
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 has for its object to provide bricks or blocks for building purposes
which shall be capable of forming a better joint with one another in the structures
of which they form a part, whereby such structures are prevented from becoming
distorted or from "settling" in process of erection, and uniformity in their joining
lines is ensured.
A brick or block constructed according to this invention is formed with pro-
jecting bands or ribs on two or more of its sides, of thickness corresponding with
the distance which it is desired to space the bricks of a structure apart from one
another; such ribs being formed either longitudinally or transversely in respect of
the length of the brick, accordingly as it is to be placed with its length parallel to
the front of the wall or structure, or at right angles thereto.
Upon reference to the annexed drawings it will be seen that such ribs may be
provided upon two sides of the brick, as shewn in Figures 1 and 2, or upon four
sides, in the form of a band, as shewn in Figure 3, the brick being designated a and
the ribs or bands b, c. The ribs or bands are spaced a short distance from the
ends or sides of the brick respectively, as will be seen.
The ribs 6 are provided
when the brick is to be laid with its length parallel to the surface of the structure
and the ribs c when its length is at right angles thereto.
In building a structure with bricks constructed according to my invention,
mortar is placed on the upper side of a brick in the usual way and the upper brick
placed upon it. The upper brick is then pressed down until the ribs on its lower
surface meet the upper surface of the lower brick (or the ribs on the upper surface
of the lower brick meet the lower surface of the upper brick, as the case may be).
The ribs formed upon the end or side of the brick also abut against the side or
end of the adjoining brick, accordingly as the length of the brick is laid parallel to
the surface of the structure or at right angles thereto. It will thus be seen that
each brick of a structure, according to my invention rests upon and abuts against
its neighbouring bricks, and not upon the intervening mortar as is now the case,
thereby preventing distortion or "settling" of such structure; and whichever way
the brick is turned there will always be ribs between it, the underneath brick, and
the brick to the immediate left hand. A saving of mortar is also effected by the
use of bricks constructed according to my invention.
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 :-
Forming bricks or blocks for building purposes with projecting ribs or bands
upon two or more of their sides, or sides and ends, in one piece therewith; substan-
tially as and for the purposes herein described with reference to the annexed
drawings.
