SPECIFICATION.
A New or Improved Automatic Valve or Plug for Ships' Boats
and the like.
I, FRANK ARTHUR SENIOR FAREWELL, Lieutenant in the Royal Navy of 1 Stanford
Road, Kensington in the County of Middlesex, do hereby declare the nature of this
invention to be as follows:-
:-
This invention relates to a new or improved automatic valve or plug for boats such
as ships boats and the like purposes and is designed to act so as to automatically drain
or empty such boats of any water therein when drawn up or lifted out of the water
and when again placed in the water will automatically close the plug holes in such
boats and prevent the admission of water through same thus obviating the risks
delays &c. when the plug is lost or becomes damaged which at present often
occurs.
For this purpose I form one or more suitable plug holes in the bottom of the
boat and such hole is automatically controlled by any suitable valve fitted therein so
as to close the said hole by the pressure of the outside water when the boat is
floating and when the boat is taken out of the water such valve will open outwardly
and so allow any water contained in the boat to run out.
The valve or automatic plug may be of any suitable construction such as a hollow
metal or other suitable ball retained in a conical shaped hole-formed in the boats
bottom by means of grating or bars or the like which latter also serve to prevent
the admission of dirt or solid matter such as seaweed &c. and so preserve the free
action of the ball valve which is pressed upwards into the narrow part of the conical
shaped plug hole when the boat is floating and so closes the plug hole and readily
drops again and so opens the plug hole when the boat is taken out of the water.
Or a back pressure or check valve may be applied in place of the foregoing ball
valve or any other form of valve suitable for the herein-described purposes.

A New or Improved Automatic Valve or Plug for Ships' Boats
and the like.
I, FRANK ARTHUR SENIOR FAREWELL Lieutenant in the Royal Navy, of 1 Stanford
Road Kensington in the County of Middlesex 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 relates to a new or improved automatic valve or plug for boats such
as ships boats and the like purposes and is designed to act so as to automatically drain
or empty such boats of any water therein when drawn up or lifted out of the
water and when again placed in the water will automatically close the plug holes in
such boats and prevent the admission of water through same thus obviating the
risks delays &c. when the plug is lost or becomes damaged, which at present of:en
occurs.
For this purpose I form one or more suitable plug holes in the bottom of the boat
and such hole is automatically controlled by any suitable valve fitted therein so as to
close the said hole by the pressure of the outside water when the boat is floating and
when the boat is taken out of the water such valve will open outwardly and so allow
any water contained in the boat to run out.

page_text: The valve or automatic plug may be of any suitable construction such as a hollow
metal or other suitable ball retained in a conical shaped hole-formed in the boats
bottom by means of grating or bars or the like which latter also serve to prevent the
admission of dirt or solid matter such as seaweed &c. and so preserve the free action
of the ball valve which is pressed upwards into the narrow part of the conical shaped
plug hole when the boat is floating and so closes the plug hole and readily drops again
and so opens the plug hole when the boat is taken out of the water.
Or a back pressure or check valve may be applied in place of the foregoing ball
valve or any other form of valve suitable for the herein described purposes.
The drawing hereunto annexed shews a valve constructed and applied in the manner
I prefer in carrying out this invention.
Figure 1 is a section through the valve. In this figure the valve is shewn as if the
boat was in the water.
Figure 2 is a plan of the upper grating and
Figure 3 is an underside view of the lower grating.
In these figures a, a is the bottom of the boat, in it is fitted the meta! conical shell
of the valve b, within this shell is the ball c, d is the upper grating formed as shewn
and is for the purpose of preventing dirt or other matter getting into the conical
shell of the valve, e is the lower grating applied on the under side of the conical shell
and secured to the bottom of the boat, this grating is also for the purpose of preventing
anything getting into the shell of the valve. The action is as follows:
When the boat is say hanging from a ships davits the ball drops into the position
shewn in dotted lines in this position any water that may be in the boat is able to
drain away through the lower grating. When the boat is waterborne the ball
assumes the position shewn by the full lines effectually closing the valve and
preventing all ingress of water. Other forms of automatic valves may be applied but
the one shewn is most advantageous as being very simple in its construction and not
liable to get out of order.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Applying to ships' boats an automatic valve in the manner described for the
purpose of allowing any water there may be in the boat to drain away when the
boat is out of the water and to automatically close the opening when the boat is
in the water.
2. Applying automatic valves to boats in the manner and for the purposes
described.
