Petty Patent Specification for the invention entitledt, T49 rotective Belt 4c:3 r-vept teozi Stpikik,

/The following statement is a full description of this invention, including the best method of performing It known to me:-

The invention described in the following statement relates

to an effective method for preventing the sinking of small to

medium-sized craft 4-20 metres in length by the use of

inflatable belts. World-wide statistics show that every year

approximately 2000 craft have been lost due to sinking. The

present invention is therefore aimed at maintaining both crew

members and the craft itself.

Sailing aids for craft are of the rigid air chamber or

cellular foam type, both of which occupy a fixed space within

10 the craft. Safety equipment for such craft have proved to be

Stoo cumbersome thus giving the craft negative buoyancy. These

and other buoyancy systems take up too much space either inside

or outside the craft and are therefore at risk of not providing

an economical, practical and secure unit. It is impossible to

control the movement of water once a craft starts sinking. It

can therefore be said that a fullproof automatic concept that So is, without the need for the crew cannot be used.

The object of the present invention is to overcome the 0" stated disadvantages of the known safety devices for small to

medium-sized craft and hence to prevent a craft from sinking,

due to either a hole in the hull or water levels reaching

critical depths. In its broadest form the invention provides

for a fixed buoyancy system for small to medium-sized craft

which is oromptly activated for positive buoyancy of a craft in

danger of sinking. It consists of a pair of reinforced

inflatable belts fixed externally beside the craft and is

operated by means of inflation by either gas or air at the time

of an emergency.

In reference to the accompanying drawings which are not

to scale

Figure 1 is a detailed section through a craft showing the protective belt in its original fixed position before

inflation.

Figure 2 is a plan of a craft showing the protective belt

before inflation.

Figure 3 is a side elevation of a craft showing the

protective belt before inflation.

10 Figure 4 is a clan of a craft showing the protective belt

after inflation.

Figure 5 is a side elevation of a craft showing the protective belt after inflation.

Figure 6 is a detailed section through the protective belt showing the Drotective belt before inflation.

Figure 1 shows the entire buoyancy system fixed internally

and externally above deck level in line with the centre of

gravity. Prior to sailing the craft a switch turns an

accumulator on which electrically operates a generator

The generator in turn pumps air into a compressor Air

is then driven from compressor into an air reservoir

which contains a set amount of air in order to inflate each

belt to a maximum volume at the time of an emergency.

When the critical moment occurs a second switch drives

air from air reservoir into a pair of harmonic-like rubber

belts via brass air pipes

When air is initially driven into air reservoir a

meter controls the air pressure so as to fill the reservoir i with the required amount of air. Inflation of the belt (7) is to be at atmospheric pressure but each belt may be inflated to about 6 p.s.i. within approximately 5 seconds.

An aerodynamic aluminium frame (10) situated at one end of

the bell is fixed at two points, internally and externally,

giving the belt sufficient stability against any movement.

An aerodynamic aluminium frame (11) (see figures 2-6) anlocks

from a spring lock (12) when air enters belt The frame

(11) together with plastic reinforcement (13) glide along a set

of ball bearings (14) located within bronze rails (15) which

are affixed to the sides of the craft at two ooints so as to

counteract friction. The belt thus becomes fully inflated

in an extended fashion.

The belt is returned to its original position by

firstly opening a non-return valve (16) which allows air out

and secondly by pulling the frame (11) by means of a reel

pulley (17) and rope (18) fixed to the top and bottom ends of

frames (10) and (11).

The accumulator generator compressor and

air reservoir are concealed by an aluminium sheet enclosure

(19) which protects the mpchinery within the craft and adds to S the aesthetics of the protective belt system.
