PROVISIONAL SPECIFICATION.
Improvements relating to the Construction of Boats to Promote their
Safety.
I, JOHN HEWES, of 4, East Street, London Road, Leicester, Agent, do hereby.
declare the nature of this invention to be as follows:-
This invention consists of improvements relating to the construction of boats
to promote their safety and has particular reference to the constructional
arrangement whereby the overturning or immersion of the boat is obviated or
greatly minimized.
In ships' boats, pleasure boats and others as at present constructed there exists
great danger of overturning from many causes.
In carrying out my invention to reduce such danger I place round the top
of the boat in any desired or suitable position tube of a diameter according
to and suitable to the size of boat to which it is attached.
The said tube may extend along the two sides or completely round the boat,
and may be of any suitable material.
I next proceed to protect the tube and provide an additional protective_belt
for the boat by carrying a sheet of metal or other suitable material all round the
boat having its outer edge turned down a suitable distance, thereby forming an
air belt all round the top edge of the boat.
It is obvious therefore that the risk of the boat capsizing is greatly minimized

Improvements relating to the Construction of Boats to Promote their
Safety.
I, JOHN HEWES, of 4, East Street, London, Road, Leicester, Agent, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention consists of improvements relating to the construction of boats
to promote their safety and has particular reference to the constructional
arrangement whereby the overturning or immersion of the boat is obviated or
greatly minimized.
In ships' boats, pleasure boats and other small craft as at present constructed
there exists great danger of overturning from many causes.
In carrying out my invention to reduce such danger I place round the top

to the boat's cubic capacity.
The said tube may extend along the two sides or completely round the boat,
and may be of any suitable material.
I next proceed to protect the tube and provide an additional protective belt
for the boat by carrying a sheet of metal or other suitable material over the
tube, having its outer edge turned down a suitable distance, thereby forming
an air-belt round the top edge of the boat.
The invention will be understood upon referring to the drawing accompanying
this specification, in which Figure 1 represents a side elevation of an ordinary
form of boat, to which the present invention is applied.
Figure 2 represents a plan and Figure 3 a section through one side thereof.
The buoyancy tubes a, a are applied longitudinally to each side of the boat for
the whole length, as shown in Figures 1 and 2, or only part thereof, and the
protective belts or covers. b, b also extend longitudinally over the said buoyancy
tubes.
The belts or covers b, b are formed of any metal not attractive to lightning and
are preferably of a section to fulfil two purposes, viz. form the protective covers
to the tubes a a as before mentioned and also ready means of holding the said
tubes in position.
The said tubes, a, a may be entirely of rubber, or composed of rubber with
one or more thicknesses of fabric incorporated therewith, the said fabric being
covered with rubber both externally and internally.
The protective belts b, b are fixed in position by screws C¹ passing therethrough
and into the gunwale C.
As shown in Figure 2, the belts b, 6 taper off to a gradually decreasing width
at each end of the boat, but it will be clearly understood that the tubes a, a
may extend round the ends of the boat and the belts b, b be kept of sufficient
width to allow of only the slight compression of the tubes a, a seen in Figure 3.
It is immaterial to give the precise details respecting the buoyancy tubes a, α
and their attachment to boats for the purpose described as their application is old
and well-understood it is the means adopted for protecting and holding the said
buoyancy tubes in position that is the essential feature of this invention.
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 ís:
-
The application to ships' boats and other small craft of buoyancy apparatus
held in position and protected in the manner herein before described with refer-
ence to the accompanying drawing.
