Improvements in Bricks.
THOMAS STERRATT Junior Oil Distiller & Refiner Farnworth Bolton do
hereby declare the nature of this invention to be as follows:-
A tongue running along the upper flat of the brick and continued down one
end, on the under Hat of the brick, and immediately opposite the tongue, I
have a V groove running full length of the brick and continued up one end, both
tongue and groove being close to the face side of the brick, hence the brick
having one flat and one end tongued, and the opposite flat and end grooved, they
lock each other completely on both sides and ends, making perfect joints that
will never require re-pointing.

COMPLETE SPECIFICATION.
Improvements in Bricks.
I, THOMAS STERRATT, Junior, of Farnworth, near Bolton, in the County of
Lancaster, Oil Distiller and Refiner, 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 :-
The invention relates primarily to outside or facing bricks and is designed to
provide a brick that will be well locked in position in the wall and which will
render the joints between the bricks impervious to the passage of moisture.
It consists essentially in forming the bricks with a V shaped tongue running
along one side and one end or two sides of the brick and a corresponding
✓ shaped groove on the opposite sides or end and immediately opposite to the
tongue.
It will be fully described with reference to the accompanying drawings which
in perspective show several forms of bricks constructed according to the
invention.
The bricks are each formed with a tongue A of V cross section running along
one side and end or two sides and a corresponding groove B of V section on
the other side and end or the other two sides.
The brick C is the more usual form and has the tongue A running the length
of the top flat and one end and the grooves B along the bottom flat and the
other end.
The brick D is constructed for the tie course and the tongue A runs across two
sides and the groove B across the other two sides.
The brick E is for the angle or return of the wall and has the tongue A and
groove B constructed on the flat sides and ends to meet the tongues and grooves
of the other bricks.
The tongue A and grooves B are preferably placed close to the front face of
the brick and the bricks being constructed as shown with one side and one end
tongued and the opposite side and end grooved they lock each other together
when built into a wall and prevent any damp entering the joints between them.
The joints will thus be well preserved and they will seldom if ever require to
be pointed.
I prefer to make the bricks slightly thicker at the front of the tongue and

sufficient mortar space between the bricks behind.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A brick formed with a V tongue on one side and end or on two sides and a
corresponding V groove on the opposite side and end or two opposite sides sub-
stantially as and for the purposes described.
