An Appliance for Automatically Emptying Bilge Water from Boats
or Vessels.
1 ALFRED JOHN HAYWARD The Wilderness Woodbridge Suffolk Gentleman
do hereby declare the nature of this invention to be as follows:-
A receptacle is formed within the boat or vessel at either side in such a position
that upon the boat or vessel being heeled to a certain degree by the wind or other
agency a portion or all of the water lying in the bottom of the boat or vessel flows
into that receptacle which is at the lower side of the boat or vessel so heeled and is

prevented from returning by a check valve or other appliance.
receptacle a pipe or other conduit is lai l across the boat or vessel having its outer
end carried through or over the side of the boat or vessel in such a position that
upon the boat or vessel being heeled in the opposite direction to that already
described the water shall then flow from the receptacle through the pipe or conduit
directly overboard. If the form or depth of the boat or vessel is of such a character
that the heeling as herein before described does not raise the receptacle containing
the water sufficiently high to discharge the water directly overboard then the pipe
or conduit must be arranged to discharge the water into a second receptacle formed
at the opposite side of the boat or vessel to that at which the first receptacle is
formed but such second receptacle must be placed in such a position that when the
boat or vessel is upon an even keel such second receptacle shall be at a higher level than
such first receptacle. From the second receptacle a pipe or conduit shall be fixed in
a similar manner to that already described but passing to the opposite side of the boat
or vessel so that upon the boat or vessel being heeled as originally described the
water may flow directly overboard from such second réceptacle. But if the level
of the second receptacle is not sufficiently high to admit of the water from it being
discharged directly overboard then a succession of receptacles with corresponding
pipes or conduits shall be arranged in a manner similar to that already described
so that the successive heelings of the boat or vessel in opposite directions shall
cause the water to flow from the first receptacle into each succeeding receptacle
until it is raised to a sufficient height to admit of its being discharged overboard.

An Appliance for Automatically Emptying Bilge Water from Boats
or Vessels.
I ALFRED JOHN HAYWARD The Wilderness Woodbridge Suffolk Gentleman
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 :-
Two receptacles are formed within the boat or vessel one at either side in such
positions that upon the boat or vessel being heeled to a sufficient degree Fig. 1

page_text: a portion or all of the bilge water W lying in the bottom of the boat or vessel
must flow into that receptacle R which is at the lower side of the boat or vessel so
heeled from which it is prevented returning by check valves or similar appliances.
From and communicating with the lower part of this receptacle a pipe or
conduit P is laid across the boat or vessel having its outer end O carried through
that side of the boat or vessel which is opposite to such receptacle at such a height
above the level of the water L W upon which the boat or vessel floats that such
outer end cannot become submerged by the heeling of the boat or vessel in the
opposite direction to that already described before the inner end of such pipe or
conduit communicating with such receptacle shall have attained to a higher level
than such outer end.
The receptacle formed at the other side of the boat or vessel is fitted in a similar
manner with valves and pipe or conduit so that the boat or vessel being heeled
alternately in opposite directions as would be the case in a vessel beating to wind-
ward each receptacle would receive bilge water when the boat was beeled in one
direction and discharge its contents through the pipe or conduit when she was
heeled in the other direction.
If the form of the boat or vessel is such that the heeling hereinbefore described
would not raise the receptacles sufficiently high to discharge their contents directly
overboard then the outer ends of the pipes or conduits instead of being carried
through the sides of the boat or vessel must be made to discharge into other
receptacles formed at a higher level in the boat or vessel than such first named
receptacles and from such second receptacles pipes or conduits must be fixed in
such manner as first described.
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. That the method of retaining the bilge water at that side of the boat or vessel
to which her heeling has caused it to flow is a novelty.
2. That utilising the alternate heeling of the vessel whereby that which was the
lower side becomes the higher and thus raising to a higher level water retained at
that lower side is a novelty.
3. That the manner of placing the pipes or conduits so as to discharge the con-
tents of the receptacles at opposite sides of the boat or vessel to such receptacles is
a novelty.
