Improvements in the Manufacture of Appliances for Saving
Life at Sea.
FREDERIC PELHAM WARREN Captain Royal Navy (retired) 67 Longridge Road
South Kensington S.W. do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention has for its objects improvements in the manufacture of appliances for
saving life at sea. With this view I construct such objects as I wish to render
buoyant, the buoyancy being obtained by their being made hollow, of paper papier
mache, pulp, wood fibre or wood pulp, treated in a suitable manner. The objects
which I propose to construct of these materials, are Life buoys, life belts, Gunwhales,
mouldings, Seats, paddle box coverings, air cases for Life, and other boats, and such
fittings in ships as can be rendered buoyant by the use of these materials, jointly or
separately.
Where paper pulp is used the pulp is pressed into a mould of the shape desired and
after being dried in the usual manner is coated or varnished with a water proof
material. In some instances the paper pulp is intimately mixed with the varnish or
waterproofing material used, before it is put into the mould.
The wood fibre is treated by being pressed into moulds in the same manner as the
paper pulp. The varnish or waterproofing material being either mixed intimately
with the pulp, or applied externally or internally as required, after it is moulded or
during the period of its being moulded.
Where the shapes are such that they cannot be formed in one piece, the desired
form is obtained by making it in separate pieces which are afterwards joined together
with Marine Glue or other suitable cement.
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 1
claim is―
1st. The use of paper or paper pulp treated in the manner above described for the
manufacture of Life buoys and Life belts.
2nd. The use of Wood pulp and Wood Fibre treated as above described for the
purposes above named and in the manner described.
Dated this 30th day of March 1888.
