MENTS IN LIFE BOATS
"
"IMPROVE-
This Invention for life boats consists mainly in the arrangements for self righting
by air and water tight compartments, which are fitted with manhole and cover for
purposes hereinafter described, also fresh water or ballast tanks and receptacles or
tanks for stowage of food or other articles.
The air and water tight compartments or head boxes are fitted at each end of
the boat, same having man hole or opening suitably secured, so that said compart-
ments are accessible for repair or otherwise.
The battens fitted to the boat are constructed of two parallel beams with a space
between to admit of ready repair or otherwise
Thwarts run across the boat at suitable intervals, and under same the fresh water
tank is placed, which also serves as ballast tank and is provided with a pump, also
buoyancy tank, and tank or other receptacle for provisioning the boat, which
answer for sheets as in ordinary life boats
Free outlets controlled by valves are applied to eject water from the boat.
The special points or features of my Invention are:-
(1.) Constructing the head boxes or air and water tight compartments with
manhole or opening suitably secured by cover, said opening being for carrying
mails or otherwise, and also for repairs being effected
(2.) The tanks or receptacles for receiving the provisions or otherwise for the
boat
(3) The tanks which are buoyant are provided with lanyards, to allow of their
being thrown overboard to assist persons in the water.
