Year: 1883

page_text: LETTERS PATENT to Herbert John Haddan, of Kensington, Middlesex
for an Invention of IMPROVEMENTS IN BUOYS OR FLOATS a communication
to him from abroad by Victor Vidal, of Pignans, France
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at the
Office of the Commissioners of Patents on the 12th June 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN BUOYS
OR FLOATS," a communication to me from abroad by Victor Vidal of Pignans,
France,
This invention has for its abject to utilise cork-waste for constructing buoys or
floats.
For this purpose I mix the cork-waste with a suitable binding material and form
therefrom a number of discs which are then laid upon each other with their flat
sides and pressed together so as to produce the necessary adhesion. After a pile or
series of discs has been thus formed, preferably in the shape of a cask, a groove is
cut on two diametrically opposite sides, a rope or band is placed in these grooves
and the ends of the band or rope are firmly tied together so as to secure the
parallel discs of cork in position. Instead of a rope and a pair of grooves two or
more pairs of grooves, and two or more ropes or ties may be applied.

by the said Herbert John Haddan in the Great Seal Patent Office on the
10th December 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN BUOYS
OR FLOATS," a communication to me from abroad by Victor Vidal, of Pignans,
France,
This invention has for its object to utilize cork waste for constructing buoys or
floats.
In describing this invention reference will be made to the accompanying drawings
of which Fig 1 is a front elevation, Fig 2 an end elevation, Fig 3 a longitudinal
section and Fig 4 a perspective view of a float with two grooves and two bands
crossing each other.
This float is composed of a number of discs a made of cork waste by mixing the
same with a suitable binding material.
The discs a, thus formed, are laid upon each other with their flat sides and
pressed together so as to produce the necessary adhesion.
After a pile or series of discs has been thus formed, a groove c is cut on two
diametrically opposite sides, which groove serves to receive a band or hoop bof
metal, or any other suitable material. The ends of this band or hoop are firmly tied
together so as to secure the parallel discs of cork in position.
After the cork discs have thus been subjected to the required pressure so as to
form a whole body the latter is dressed by hand or machine and converted into a
suitable shape, preferably into the shape of a cask, (see drawing).
The buoy or float may be composed of discs formed of whole pieces of cork which
are first suitably dressed and then pressed and tied together in the manner above
described. Instead of two pairs of grooves diametrically opposite each other and
two ties, any other suitable number may be adopted.
CLAIM:
A float or buoy composed of discs or pieces of cork held together by means of a
tie or ties placed in grooves, substantially as described.
In witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this tenth day of December A.D. 1883.
