PROVISIONAL SPECIFICATION.
Improvements in Bricks for Building Purposes.
We HENRY WARRINGTON and HENRY JAMES WARRINGTON, of Berry Hill
Works, Stoke-on-Trent, in the County of Stafford, Ironmasters, do hereby declare
the nature of this invention to be as follows :-
This invention relates to improvements in bricks for building purposes and
consists in forming such bricks with a rectangular recess or cut-away portion at
one end and a corresponding projection at the other end so that when such bricks
are laid in courses the projecting end of one brick enters the recessed end of the
other and forms a sort of lock-joint.
By forming the projection somewhat longer than the recess, a space for mortar
or other consolidating material is provided between the adjacent ends of the bricks
and by limiting the application of the mortar to this space, the exposed joint
presents the appearance of a mere line, the adjacent surfaces being in close juxta-
position thus improving the appearance of the work and affording protection to
the lime or mortar from atmospheric influences.
The improvements are of course applicable to all sorts of bricks, but the con-
struction will vary according to the position which the brick is destined to occupy
in the building, that is to say according as it may be a "full front," "corner-
brick" or "through."

COMPLETE SPECIFICATION.
Improvements in Bricks for Building Purposes.
We HENRY WARRINGTON and HENRY JAMES WARRINGTON, of Berry Hill
Works, Stoke-on-Trent in the County of Stafford, Ironmasters 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 improvements in bricks for building purposes, and has
for its object, to so form such bricks that they will fit together, when laid in courses,
so as to form a class of lock-joint, thereby rendering the consolidating of one brick
with another, more secure, the further objects of the invention being, to render the
exposed joints more sightly than heretofore, and to protect the mortar or other
consolidating material employed to bind the bricks together, from atmospheric
influences. And in order that our invention may be the more readily understood,
we have shown same upon the accompanying sheet of drawings, wherein :-
Fig. 1 is a perspective view of a "full front" brick constructed according to our
invention.
Fig. 2 is a like view of a "through brick."

Fig. 3 being a similar view of a corner brick."
Fig. 4 is a course of brick work shewing the appearance of the exposed joints
when our improved form of brick is employed, while,
Fig. 5 is a view of a course, wherein the old form of brick is used.
a is a brick having formed at one of its ends a rectangular recess or cut away
portion b, and a corresponding projection c at its other end.
The projection c, when the bricks are laid in courses enters the recess 6 formed
in the end of the next brick, and forms, thereby, a kind of lock-joint. We also

page_text: form the projection c somewhat longer than the recess b, so as to provide, thereby,
a space for receiving the mortar or other consolidating material employed for
binding the bricks together, between the adjacent ends of the bricks, and by
limiting the application of the mortar to this space, the exposed joint will present
the appearance of a mere line, in consequence of the adjacent surfaces b and c being
in such close justa-position, one with the other.
In consequence of the surfaces of the projection c and recess b being in such
close justa-position the appearance of the exposed joint will be considerably
improved, and the lime or mortar comprising the consolidating mixture, will by
reason of being behind the joint, be protected from atmospheric influences. We
further form the upper part of each brick with a projection d (shewn underneath
in the drawings the bricks being turned over for convenience of illustration) rising
from the front of same. By providing this projection, a space is left between the
upper surface of the lower brick, and the lower surface of the upper one, imme-
diately behind the exposed joint and extending to the rear of the bricks, for
receiving mortar or other consolidating material when the bricks are laid in
courses.
We may also, if desirable, slightly recess, or cut away, the under surface of the
front of the brick to form a shallow bed in order to let the upwardly projecting
portion of the under brick rest in same: The improvements are applicable to all
classes and forms of bricks used in connection with building.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
(1) The improvements in bricks for building purposes, consisting of forming
same with a rectangular recess or cut-away portion at one end and a corresponding
projection at the other end, and with the upper portions of such bricks with a front
vertical projection, respectively, and with their corresponding under surfaces,
slightly recessed, substantially as and for the purpose described and illustrated.
(2) The improvements in bricks for building purposes substantially as herein
before described, and illustrated by the drawings.
