I, FRED SNOW SMITH, of 2, Wells Walk, Ilkley, in the County of York, Archi-
tect, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to manufacture bricks and the like moulded
building blocks of such a shape that the joints of the same are positively weather-
proof.
I tongue and groove each brick so that in cross section each brick on its
underside is grooved or hollowed and on its top side it is tongued or has a pro-
jection, the tongue of the underneath brick fitting into the groove of the upper
brick and so on.
Or the tongues and grooves may be in any other suitable position according
to the position of the block.

Improvements in the Construction of Bricks and other Moulded
Building Materials.
I, FRED SNOW SMITH, of 2, Wells Walk, Ilkley, in the County of York, Archi-
tect, 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 object of my invention is to manufacture bricks and the like moulded
building blocks in such shapes that the joints are positively weatherproof.
In the accompanying drawings; -

Fig. 4 is an end elevation of Fig. 3.
Fig. 5 is a side elevation of half-brick for use as in Fig. 3.
Fig. 6 is an end elevation of Fig. 5.
Figs. 7 and 9 are side elevations of bricks used at the angle or quoin of a wall.
Fig. 8 is a plan of Fig. 7.
Fig. 10 is a plan of Fig. 9.
Fig. 11 is an end elevation of brick used as a header in walls where the facing
only is built of my improved locking bricks.
Fig. 12 is a plan of Fig. 11.
Fig. 13 is an end elevation of header brick for walls built entirely of my
improved locking bricks.
Fig. 14 is a plan of Fig. 13.
Fig. 15 shows the construction of an angle or quoin of a half-brick wall.
I construct my improved brick (see Figs. 1 and 2) with a tongue or rib A on
its upper side, and a corresponding recess or groove B on its under side.
The bricks are laid with the said tongues and recesses parallel to the face of
the wall, the tongue or rib on each brick fitting into the recess or groove in the
brick or bricks immediately above it, so that the horizontal joints between the
various courses are continuously broken, so preventing the passage of moisture
between the courses. The bricks have also a short projecting tongue C at one
end between the tongue or rib A and the recess or groove B, and a corresponding
recess at the other end, so that each vertical joint is also broken and the passage
of moisture between adjacent bricks is entirely prevented. By this means
positively weather-proof and also much stronger wall may be constructed.
To simplify the moulding and laying of the bricks the said tongues or ribs A
and the recesses or grooves B, and also the tongues C and recesses D, are made
tapered towards the top.
a
The brick may be made in various modifications to suit different positions in
the wall or building. Thus for the return end of a wall, or for a door or window
reveal, the brick may be made (as shown in Figs. to 6) with the tongue or rib A
and the recess or groove B extending only part of its length. For angles or
quoins the brick is made (as shown in Figs. 7 to 10 and Fig. 15) with angular
tongues or ribs parallel to the two faces of the wall, and correspondingly angular
recesses or grooves. The bricks may be laid in any style of bond, the ribs and
recesses in the header bricks being transverse, so as to be parallel with the face
of the wall. The said header bricks may have either single or double ribs and
recesses (see Figs. 11 to 14), according as the wall is only faced with locking
bricks or is built entirely of locking bricks.
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. A brick or the like moulded building block formed with a longitudinal rib
tapered towards the top and a corresponding groove opposite the said longitudinal
rib, and having also at one end a short projecting tongue tapered towards the
top, with a corresponding recess at the opposite end, substantially as, and for the
purposes, shown and described.
2. A brick or the like moulded building block formed with either a single or
double transverse rib tapered towards the top and a corresponding groove or
grooves opposite the said transverse rib or ribs, and having also at one side a
short projecting tongue or tongues tapered towards the top, with a corresponding
recess or recesses at the opposite side, substantially as, and for the purposes,
shown and described.
3. A brick or the like moulded building block formed with an angular rib
tapered towards the top and a corresponding groove opposite the said angular rib,

towards the top, with a corresponding recess at the other end of the said angular
rib, substantially as, and for the purposes, shown and described.
