the County of Middlesex, Lieutenant Royal Marines, for the
Invention of "IMPROVED MEANS OF RAISING SAND OR SHINGLE COVERED BY
THE TIDE TO THE LEVEL OF HIGH WATER, AND THEREWITH FORMING EMBANK-
MENTS FOR THE CONSTRUCTION OF SEA WORKS."
Sealed the 14th June 1872, and dated the 12th April 1872.
PROVISIONAL SPECIFICATION left by the said Edward Manico at the
Office of the Commissioners of Patents, with his Petition, on the
12th April 1872.
I, EDWARD MANICO, of Bedford Street, Strand, in the County of
Middlesex, Lieutenant Royal Marines, do hereby declare the nature of
the said Invention for "IMPROVED MEANS OF RAISING SAND OR SHINGLE
COVERED BY THE TIDE TO THE LEVEL OF HIGH WATER, AND THEREWITH FORMING
EMBANKMENTS FOR THE CONSTRUCTION OF SEA WORKS," to be as follows :-
This Invention relates to certain improvements upon the means of
forming embankments for the construction of sea works set forth in

page_text: In lieu of placing my cradles or caissons side to side when square
shaped, or dovetailing them into each other when suitably shaped for
that purpose, as set forth in the above-mentioned Specifications, I uso
only square or oblong square cradles and place them edge to edge, as
the cradles marked A on the Drawing, strengthening the row thus formed 5
by an additional cradle set at the back or shore side of the row in every
alternate recess formed by the diagonal position of the cradles, as illus-
trated by the cradles marked B on the Drawing.
In some cases I may find it sufficient to strengthen my row of
diagonally placed cradles by an additional cradle at longer intervals than 1
each alternate recess, or I may strengthen the row by additional cradles
as at B, B", Fig. 3. When placed above low water mark I may in
some cases cramp my diagonally placed cradles at the corners a which are
in contact, using any kind of iron cramp or other tie pieces which I may
find suitable. My cradles are made of wrought-iron bars interlaced (I 1
prefer to use flat bar iron of 14 by ½ inch) are partially filled with
stones and must have brushwood or an equivalent material intertwisted
amongst their openings.
The embankment or sea slope will be formed by the action of the
tide, which in its flux and reflux will gradually fill my cradles with 2
sand and shingle, and heap sand and shingle between the first row Ċ
and the second row D of my diagonally placed cradles (see Fig. 6) and
between every succeeding row which may be placed behind them to
raise the embankment to the required, height, the slope from the upper
tier F to the lowest C being a perfectly natural one.
Having now described the nature of my said Invention, and in what
manner the same is or may be performed, I would have it understood
that I make no claim to the construction of open cradles or caissons;
but that what I claim as secured to me by the herein-before in part
recited Letters Patent is the use of,—
Firstly. The combination of the cradles or caissons edge to edge
diagonally, substantially as and for the purposes herein-before set
forth.
Secondly. The combination with the rows of diagonally placed cradles
pr caissons of an additional cradle placed on the shore side of the row
in each alternate recess or at longer or shorter intervals, substantially
as and for the purpose herein-before set forth.

page_text: Thirdly. The cramping of the diagonally placed cradles or caissons at
the corners in contact, substantially as and for the purpose herein-before
set forth.
In witness whereof, I, the said Edward Manico, have hereunto set
my hand and seal, this Eleventh day of September, in the year
of our Lord One thousand eight hundred and seventy-two.
