I HERBERT WILLIAM HART of 124 Chancery Lane in the City of London and
County of Middlesex do hereby declare the nature of my Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF BRICKS ALSO APPLICABLE TO TILES" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to improvements upon Letters Patent granted to me
bearing date the 8th day of April 1879 N° 1392 according to which the bedding
and butting faces of-bricks used for building purposes are formed alternately with
broad grooves or recesses tapered at the sides and with projecting pieces or joggles
for taking into these broad grooves or recesses.
Now my invention has for its object to reduce the quantity of mortar or cement
required in laying such bricks, to cheapen the cost of their construction and at the
same time increase their strength.
On the accompanying drawing figure 1. represents a sectional elevation of a
series of bricks constructed according to my invention and figure 2 a plan thereof
like letters of reference indicating corresponding parts in both figures.
My invention consists in dispensing with the broad grooves or recesses described
in the said Letters Patent and substituting therefor on one side or bedding face of
each brick a two square (or rectangular) shaped recesses or pockets b the sides of
which are tapered (or they may be vertical) and into which take corresponding
projections or joggles c formed on the opposite side or bedding face of each
succeeding brick a¹.
A space is left between the sides and bedding surfaces of the recesses b and
joggles c for the reception of mortar or cement:
:
By this invention there, will be no space left between the bricks a. a. except
where the recesses or pockets b are taken into by the joggles c. the spaces thereat
being occupied by the mortar or cement whilst a small layer or quantity only of
the latter will be required between the bedding or butting faces of the bricks a. a¹.
-By this means the quantity of mortar or cement used in laying the bricks a. a¹.
is reduced to a minimum and by retaining the full capacity of the bricks their
strength is increased and the cost of making lessened.
If preferred the recesses and joggles may be of a circular shape as shewn in plan
figure 3 or they may be of an elliptical diamond or any other desired shape.-The
invention is also applicable to tiles for roofing and flooring purposes.
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
Constructing bricks on one of their sides or bedding faces with recesses or
pockets and on their opposite sides or bedding faces with projections or joggles
substantially as and for the purposes hereinbefore described and illustrated by the
accompanying drawing.
Dated this 5th day or November 1007.
