IMPROVEMENTS IN THE CONSTRUCTION OF BREAKWATERS RETAINING WALLS AND OTHER LIKE STRUCTURES
Year: 1884

Civil Engineer do hereby declare the nature of said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF BREAKWATERS RETAINING WALLS AND OTHER LIKE
STRUCTURES" to be as follows:-
My Invention has reference to the construction of breakwaters retaining walls
and other like structures as described in the Specification of Letters Patent
No 1695 granted to me as of the 8th April 1882 and has for its object to so form
or construct the bricks blocks or component parts of such structures that the bricks
blocks or component parts of each individual column of the structure are made to
interlock with each other that is to say so that each brick block or component part
engages or interlocks with the bricks blocks or component parts above and below
it. This is effected by making projections and recesses on the upper and under
sides of the bricks blocks or component parts for example there may be two
circular projections on the upper side and two corresponding recesses in the lower
side of each brick block or component part so that when the columns are built up
the recesses in the upper sides of the bricks blocks or component parts engage in
the recesses in the under side of the brick block or component part next above it
but I do not limit myself to the number shape size or position of the said projections
and recesses.
The bricks blocks or component parts are or may be in other respects formed as
described in my aforesaid Specification but the beds thereof may be made truly
horizontal instead of at right angles or square with the line of the column. This
will render it unnecessary to provide specially formed bricks or blocks at top and
bottom of the Columns. By the use of bricks blocks or component parts formed or
constructed as herein before described the truth of the columns is more accurately
preserved and their independent individual settlement better secured.

Civil Engineer do hereby declare the nature of said invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF BREAKWATERS RETAINING WALLS AND OTHER LIKE
STRUCTURES" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My Invention has reference to the construction of breakwaters retaining walls
and other like structures according to a former Invention of mine as described in
the Specification of Letters Patent No 1695 granted to me as of the 8th April 1882
and has for its object to so form or construct the blocks or component parts of such
structures that the blocks or component parts of each individual column of the
structure are made to interlock with each other that is to say so that each block
or component part engages or interlocks with the blocks or component parts above
and below it.
This is effected by forming studs or projections a² and recesses on the upper
and under sides of the blocks or component parts as illustrated in the accompanying
drawings wherein Figure 1 is a plan. Figures 2 and 3 are front elevations
Figure 4 is a side elevation of a portion of a breakwater retaining wall or like
structure arranged according to my aforesaid former Invention and provided with
additions in accordance with my present Invention-Figure 5 is a front elevation,
Figure 6 a side elevation-Figure 7 a plan of a separate block or component part
of such structure-In these I have shewn as an example two circular projections a²
on the upper side and two corresponding recesses b in the lower side of each block
or component part so that when the columns are built up the projections a² and
recesses bon and in adjacent blocks or component parts engage together and secure
together the blocks or component parts of each of the columns of blocks or
component parts into which the structure is divided as described in my Specification
aforesaid I do not limit myself to the number shape size or position of the said
projections and recesses.
The blocks or component parts are or may be in other respects formed as
described in my aforesaid Specification but the beds thereof may be made truly
horizontal as shewn in accompanying Drawing instead of at right angles or
square with the line of the column as shewn in my former Patent 1695, 8th April
1882 This will render it unnecessary to provide specially formed blocks at top
and bottom of the columns-By the use of blocks or component parts formed or
constructed as hereinbefore described the truth of the Columns is more accurately
preserved and their independent individual settlement better secured.
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 and for the construction of breakwaters retaining walls and other like
structures the manufacture and employment of blocks or component parts formed
or constructed substantially as herein before described so that the blocks or com-
ponent parts of each individual column of the structure are made to interlock or
engage with each other.
