I, JOHN QUIGLEY, of Blossburg, in the County of Tioga, and State of Pennsylvania,
United States of America, Gentleman, 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 brick making and particularly to a brick, and the
object of the invention is to provide a brick of such peculiar and novel construction
that no mortar is required in joining the same.
A further object of the invention is to provide a brick having upon all sides and
ends means for joining it to other bricks, without employing motar, cement, or other
adhesive material.
The invention consists in the peculiar and novel construction of the brick and
resides essentially in the special arrangement thereon of means for joining it to other
bricks without motar or other adhesive material.
In the drawings:-
Fig. 1 is a perspective view of several of my bricks joined together forming part
of a wall.
Fig. 2 is a perspective view of my brick upon a larger scale.
Fig. 3 is a longitudinal central section on the line x-x Fig. 2.
Fig. 4 is a cross section on the line y-y Fig. 2.
Fig. 5 is a perspective view of a modified form of brick.
Fig. 6 is a cross section of an inner brick.
The same letters of reference denote the same parts throughout the several figures
of the drawings.
The brick hereinafter to be fully described is intended for walls in structures of
various character and while it has special reference to buildings, it may be found not
only desirable but exceedingly beneficial when used in furnace linings and furnace
walls where heat is so great as to cause expansion and contraction of the lining
or wall.
The front bricks A, that is, the bricks employed to form the front of the wall have
a horizontal shoulder a, and vertical shoulder b, upon one edge and one end, which
form grooves B by having the square edges of the adjoining bricks placed hard
against the shoulder portions of the brick. This groove may be filled with material
to form ornamental dividing lines between the bricks.
One end of the brick has a vertical angular groove C and the other end has an
angular tongue or projection D. The top of the brick has round projections E and
directly opposite the same in the bottom of the brick is formed corresponding
cavities F, and a like cavity G is formed in the centre of the rear face of the brick to
receive a plug, to which lathing may be secured when only one course of bricks are
employed in the wall.
The inner or rear bricks H have their top and bottom surfaces, ends, and one side
constructed identically with that of the brick A, hereinbefore described, except the
shoulders a, and b, are omitted, and with the addition of a round projection h,
opposite the cavity G in the side of the brick.

page_text: It will be observed that in building a wall of my improved brick every brick in the
wall except the front bricks are joined or bound together upon the top and bottom
and upon each side by projections and cavities, and the ends of each brick including the
front bricks are joined or bound together by the tongue and groove connection,
hereinbefore described. Owing to this perfectly rigid connection between the bricks
forming a wall it is impossible for the bricks to be moved or become misplaced by the
settling of the wall or from the contraction and expansion of the same.
Referring to the modification shown in Fig. 5, one side of the brick has a vertical
groove I, upon each side of the cavity f, and directly opposite on the other side of the
brick are corresponding tongues g.
This construction provides an additional tie between the sides of the bricks, and it
is obvious that each course of bricks is not only tied with the course above and
below but is firmly and securely bound with the course upon each side.
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
1. As an improved article of manufacture, a brick provided with projections upon
its top and corresponding cavities upon its bottom, a cavity upon one side, and a
corresponding projection upon the other side, a vertical tongue upon one end, and a
corresponding vertical groove upon the other end, substantially as set forth.
2. A brick having a vertical shoulder and a horizontal shoulder,projections upon its
top, and corresponding cavities in its bottom, a vertical tongue upon one end and a
corresponding vertical groove upon the other end, substantially as set forth.
3. The outside brick having projections upon its top, corresponding cavities upon
its bottom, a cavity upon the inner side adapted to receive a corresponding projection
of an inside brick, a vertical tongue upon one end, and a corresponding groove upon
the other end.
