IN BUILDINGS WALLS AND OTHER STRUCTURES a communication from abroad by

ور
This Invention relates to improvements in the construction of walls and houses
or other structures and in the bricks blocks or component parts used in such
construction and has for its objects to enable a structure of great solidity to be
made with economy and rapidity and if desired without the use of Mortar or
binding Cement.
According to. the said Invention the bricks blocks or component parts of which
a structure is to be composed are formed with a rib or ribs or projection or
projections from their top bottom or sides one more or all of them and corresponding
recesses are made in the top bottom or sides of the blocks which are to be placed
in juxtaposition to these projecting portions of the first mentioned blocks. A
convenient form for plain walls and like structures will be to make the upper side
of each alternate block with a rib or ribs extending therealong along and partly
down the sides the under part having a longitudinal groove or recess therein
corresponding in size to the rib above The intermediate blocks are made with a
rib projecting from the upper side for a part only of the length of the block and
recesses are formed at the sides and bottom part. In placing these blocks together
to form a structure the projecting side portions of the first mentioned blocks are
placed in the side recesses of the adjacent blocks the projecting ribs from the upper
parts of all the blocks forming a retaining rib to engage with the recesses in the
underside of the next tier. For making corners the blocks may be L shape in plan
and for abutting or crossing walls they may be T shaped or of the form of a cross
in plan.--Where the walls are to be of a greater thickness than one block the side
abutting faces of adjacent bricks in the same horizontal plane are furnished with
engaging ribs or projections and recesses respectively as before described.-The
[Price 2d.]

page_text: unrubbed or unrecessed faces of the blocks which are to form the outer surfaces of
the structure for example an arch or moulding or plain outer facing may be
rounded or constructed of any configuration to meet the special requirements of
each case.
The blocks may be of ordinary brick material moulded and burnt after the
manner in which such bricks are ordinarily made or they may be of any other
convenient or suitable material. Where wood is to be used in the structure in
combination with the herein before described improved blocks the wood will have
formed or fixed thereto ribs projections or recesses to engage with the adjacent
recesses or projections or ribs of the blocks next to which they are placed.
Chimneys may be readily made of the bricks blocks or component parts with the
central part hollow.
