Improvements in Bricks
Year: 1897

page_text: I ROBERT BALAAM of the firm of Balaam Brothers, Builders & Contractors,
Shenton Street, Old Kent Road, S.E., do hereby declare the nature of this invention
to be as follows:-
The present invention relates more particularly to glazed bricks suitable for use
in lining swimming baths &c.
According to ordinary methods, swimming baths are usually made water-tight by
lining the sides and bottom with a coating of asphalte, upon which glazed bricks or
tiles may be afterwards cemented.
The object of my invention is to provide a lining brick which will render the bath
perfectly water-tight without the aid of the asphalte now commonly employed.
According to my invention, the lining brick is made with a glazed face as usual,
and with a back of the ordinary form; the sides and ends, however, are furnished with
channels extending around the brick, between ridges or flanges of which the back
flange is broken away or notched at intervals.
Bricks of this form are built together on the walls and floor of concrete or other
material, which forms the sides and bottom of the bath, and are secured in place by
cement. The cement fills up the recesses between the bricks, and keys them
together, and locks them tightly to the supporting wall or floor, with the aid of the
notches above mentioned.
The bricks for forming the vertical and horizontal angles and corners of the bath
are of special sizes and shape to make them fit together, but in each case the edges
and sides are furnished with the grooves as aforesaid.
Dated this 2nd day of March 1897.

Improvements in Bricks."
I ROBERT BALAAM of the Firm of Balaam Brothers, Builders and Contractors,
Shenton Street, Old Kent Road S.E. 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 present invention relates to bricks or tiles to be used in building swimming
baths, ponds, tanks, and similar structures, intended to hold water without
leaking.
According to ordinary methods, swimming baths and the like are usually made
water tight by lining the sides and bottom with a coating of asphalte, upon which
glazed bricks or tiles may be afterwards cemented.
The object of my invention is to provide a lining brick which will render the
bath perfectly water-tight, without the aid of the asphalte now commonly employed.

page_text: According to my invention the lining brick is made with a glazed face, as usual,
and with a back of the ordinary form; the sides and ends, however, are furnished with
channels extending around the brick between ridges or flanges, of which the back
flange is notched at intervals, as hereafter explained.
In the accompanying drawings I have shown a portion of a swimming bath built
according to my invention and also detached bricks of the different shapes necessary
for building the bottom and sides, and for forming the angles and corners.
Fig 1 is a perspective view of a corner of a bath, shewing the different forms of
brick in position.
Figs 2 are detached plan, back and side views of the angle brick used to join the
floor of the bath with the walls.
:
Figs 3 are similar views of the brick used at the corners of the bath at the
bottom.
Figs 4 are back, end and side views of the brick used for the walls and bottom of
the bath; and
Figs 5 are plan view and elevation of a pair of bricks to be used at the vertical
angles; and
Fig. 5 is a face view of one of them.
On referring to the drawings it will be seen that every form of brick has its sides
and ends channelled. a are the channels extending between flanges b b¹.
The back flanges 61 is broken away at intervals, to made dovetailed notches d.
In building a swimming bath according to my invention a rectangular structure is
first made by building walls and bottom A and B of concrete or other suitable
building material. The bottom and walls are then lined with the channelled and
notched glazed bricks or tiles of a thickness suitable for the work in hand.
D are the flat bricks for the bottom and sides (see Figs : 4). C are the angle
bricks (see Figs: 2) for joining the sides and ends with the bottom. E is the corner
brick (see Figs: 3) used where the bottoin sides and ends meet. FF are the
vertical angle bricks used alternately with the curved brick G, which is not shown
detached, but which is similar to the brick C, except that it is only half the length
of the latter.
The employment of two forms of brick for the vertical angles facilitates the laying
of the bricks, so that each course breaks joint with the next in the manner shewn in
Fig: 1.
When the bricks are thus built together on the walls and floor of concrete or other
material which forms the sides and bottom of the bath, and are secured in place by
cement, the cement fills up the recesses between the bricks and keep them together
and locks them tightly to the supporting wall or floor, with the aid of the dovetailed
notches & above mentioned, and renders the structure completely watertight.
The flat bricks D are for the most part, rectangular but some are taper
longitudinally; these are used for the sides when the bottom is inclined to give a
graduated depth to the bath.
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:
In building swimming baths and similar structures the employment of the above
described channelled lining bricks, arranged and fitted as explained for the
purpose set forth.
