IMPROVEMENTS IN OYSTER BEDS be as follows
Year: 1884

page_text: I ASTLEY PASTON PRICE of 47 Lincolns Inn Fields in the County of Middlesex,
Gentleman, do hereby declare the nature of said invention for "IMPROVEMENTS IN
OYSTER BEDS to be as follows:-
"
Hitherto in the cultivation of oysters it has been customary to lay or place what
is known as Cultch that is to say :-Oyster-and cockle shells on the Bed and fore-
shore of the Oyster-ground in order that the Oyster spat may be arrested and
become attached to the surface of the Cultch.
Now this Invention relates to the rendering of the surface or surfaces of the
before mentioned Cultch or other material or substances more capable of arresting
and retaining the oyster spat and consists in covering the same with a water
resisting and roughened material such for example as Hydraulic Cement or of a
mixture of Tar or Bitumen or similar substance or materials and rendering the
surface or surfaces rough and uneven by the application of a water resisting
material such as divided Cultch or Burnt Clay or sand or other equivalent.

page_text: I ASTLEY PASTON PRICE of 47 Lincolns Inn Fields in the County of Middlesex,
Gentleman do hereby declare the nature of said invention for "IMPROVEMENTS IN
OYSTER BEDS" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Hitherto in the cultivation of Oysters it has been customary to lay or place what
is known as cultch that is to say-Oyster and cockle shells on the bed and fore-
shore of the Oyster ground in order that the Oyster spat may be arrested and
become attached to the surface of the cultch.
Now this Invention relates to the rendering of the surface or surfaces of the
before mentioned cultch or other material or substances more capable of arresting
and retaining the Oyster Spat and consists in covering the same with a water
resisting and roughened material such for example as hydraulic cement or of a
mixture of Tar or Bitumen or similar substance or materials and rendering the
surface or surfaces rough and uneven by the application of a water resisting
material such for example as divided cultch or burnt clay or sand or other
equivalent.
In carrying out my Invention I cause what is known as cultch namely Oyster
shells, cockle shells or other shells or other material or materials to be coated with
a water resisting material such for example as Hydraulic cement which may be
effected by bringing the before mentioned cultch or other material or materials into
contact with Hydraulic Cement when in a semifluid or pasty condition, and after
having effected the coating or covering of the same, removing the same and taking
precaution that the cultch or other material or materials thus coated or covered
shall be Isolated and singled and then by preference before the Hydraulic cement
has sett applying in a divided condition either Hydraulic cement or divided cultch
Burnt clay or any other water resisting material in order that the surface may be
rendered rough and uneven, and thus offering greater facility for the attachment of
the floating Oyster Spat.
Or instead of coating or covering the before mentioned materials with Hydraulic
Cement I cause the same to be coated or covered with either tar pitch Bitumen or
mixtures of the same or with other similar substances and then rendering the
surfaces of such before mentioned materials rough and uneven by the application
of any divided water resisting materials such for example as disintegrated shells,
Burnt clay, or other water resisting material.
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 as my Improvements in the cultivation of Oysters is
The treatment and preparation of what is known as cultch or other material or
materials so as to render the surface or surfaces of the same better capable of
arresting the floating Oyster Spat substantially in the manner hereinbefore described.
Dated this 21st day of January 1885.
