PROVISIONAL SPECIFICATION.
Method of Causing Water to be Automatically Discharged from a
Leaky or Water-logged Boat or other Vessel in Rough Water.
We, WILLIAM COOPER, Neptune Engine Works, Engineer, and JOHN
HOLDSWORTH, 27, John Street, Traveller, both of Hull, in the County of York,
do hereby declare the nature of this invention to be as follows
:-
We fix a water-tight partition or bulkhead across a boat or larger vessel, a short
distance from each end; in an inclined position; thereby forming a compartment
or trap at each end of the vessel; from which there is only an outlet through a
pipe, hose, tunnel, or conduit (excepting over the top of the partition) which is
inserted at, or near the bottom, or other suitable place of the compartment; led
to the opposite end of the boat or vessel, and over, or through the bow and stern.
The motion of the vessel causes the water contained in it, to alternately wash or
surge from end to end, to enter the then lower compartment or trap, either over
the partition or bulkhead, through a suitable check return valve, or door, or by
both means; and to be automatically discharged through the pipe, hose, tunnel,
or conduit, when the position of the vessel is reversed.
We may employ a check-return valve in the pipes, hose, tunnels, or conduits
if desired.
Dated this Tenth day of June 1890.

COMPLETE SPECIFICATION.
Method of Causing, Water to be Automatically Discharged from a
Leaky or Water-logged Boat or other Vessel in Rough Water.
We, WILLIAM COOPER, Neptune Engine Works, Engineer, and Jonx
HOLDSWORTH, 27, John Street, Traveller, both of Hull, in the County of York,
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:-
We fix a water-tight partition or bulkhead A. across a boat, or larger vessel,
a short distance from cach end, or from one end only, in an inclined, or vertical
position, thereby forming a compartment, trap, tank, or receptacle, B. at each, or
at one end of the boat or vessel, from which there is only an outlet through a pipe,
hose, tunnel, or conduit C. C' in Figs. 1 & 2, and C. in Figs. 3. 4. 5 & 6. (excepting
over the top of the partition when not covered in) which is inserted at or near the
bottom, or other suitable place of the compartment, trap, tank, or receptacle B., led
to the opposite end of the boat or vessel, and over or through the bow and stern,
or in proximity to them. The motion of the vessel causes the water contained in
it to alternately wash or surge from end to end, to enter the then lower compartment,
trap, tank, or receptacle over the partition or bulkhead A. through a suitable
check-return valve or door D., or by both means; and to be automatically
discharged through the pipe, hose, tunnel, or conduit C, or C₁ led through the
boat, or vessel as shown, or over the gunwale.
We may employ a check-return valve as shown at E. Fig. 1. or its equivalent,
with the pipes, hoses, tunnels, or conduits if desired, for the purpose of keeping
them full, and to prevent any outside water from entering them if submerged.
We may produce the same result by employing one pipe, hose, tunnel, or

page_text: conduit only Figs. 3. 4. 5 & 6 along the bottom of the boat or vessel, connecting
the two compartments, traps, tanks or receptacles B. B., and doing service for both
with the intervention of the valves and boxes F. F. Fig. 3 which valves may also
do duty instead of those shown at E. Fig. 1., or work in unison with them.
These valves allow the water to escape out of the compartments, traps, tanks, or
receptacles B. B. through the boxes F. F. and pipe, hose, tunnel, or conduit C 3
and thence through the outlet pipes G. G., overboard; but not to enter them.
Or, (as shown by Fig. 5.) instead of continuing the pipes, hoses, tunnels, or
conduits through the bulkheads (as per Fig. 1) or otherwise leading them to
discharge overboard; we may simply connect the two compartments, traps, tanks,
or receptacles by them; or by one only, which is sufficient in this case also.
The result of this arrangement is to cause the lower compartment, trap, tank
or receptacle to be so surcharged with the water from the higher one; through the
pipe, hose, tunnel, or conduit C., in addition to that which it receives through the
valve D. from the body or hold of the boat or vessel; as to overflow or discharge
through a hole or holes (provided with a check-return valve or valves E Fig. 1.
or without) in one or in both compartments, traps, tanks, or receptacles; or over
the gunwale, overboard.
If one only of these compartments, traps, tanks, or receptacles be pierced with
an outlet or discharging hole, or holes, a greater volume of water will be discharged
at each alternate pitch of the boat or vessel, and will act in smoother water than
if both compartments, traps, tanks, or receptacles be so pierced; as the unpierced
one receives (when in the lower position) its supply unitedly from the body or
hold of the boat or vessel, and from that which remains undischarged in the
pierced one, the whole of which it takes up with it to the higher level, and
discharges it into the then lower or pierced one, thence, through the outlet or
discharging hole or holes, into the sea.
This arrangement may be made to discharge at each pitch of the boat or vessel
if desired, by providing two compartments, traps, tanks, or receptacles at each end,
or by dividing those already described, and connecting each pair by a separate
pipe, hose, tunnel, or conduit C. But to more effectually drain or clear the boat or
vessel of water, and to render still less pitching necessary, we may employ one
outlet pipe or valve F. Fig. 6. discharging athwart or in any desirable direction,
by means of the pipe G or other suitable duct.
By this modification, the approximate contents of both compartments, traps,
tanks, or receptacles are discharged direct from the higher level through the
pipe, hose, tunnel, or conduit C, valve box F. and pipe or duct G into the sea,
without having to mix with and swell the contents of the then lower compartment,
trap, tank, or receptacle to discharging level as in Fig. 5.
As so much less pitch is necessary with this arrangement, the outlet pipe or
duct G. need not necessarily be placed at either extreme end of the boat or vessel,
or in near proximity to it, but may be nearer "amidships" if desired, and may be
led athwart to discharge on both sides, to which the roll" of the boat or vessel
would contribute some advantage.
This modification also, can be so arranged as to discharge at each pitch, of the
boat or vessel if desired, instead of alternately by having two separate compart-
ments, traps, tanks, or receptacles at each end, or by dividing those already
described, and providing each with its valves, connecting pipe, hose, tunnel, or
conduit, and outlet pipe as described in the single arrangement by Fig. 6.
This invention may also be applied to work by the roll of a vessel if desired in
any case, and we anticipate that it may be also applicable to vessels of a larger
type than open boats.
Other modifications in the construction of the compartments, traps, tanks, or
receptacles, valves and pipes, hoses, tunnels, or conduits, all of which may be of a
portable description; and valves of the "ball," or other type, may be adopted
without departing from the nature of our invention and we do not limit ourselves
to the precise details shown by the drawings.

page_text: Having now particularly described, and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is :-
The method of utilising the pitching, and rolling motions of a vessel; in
combination with compartments, traps, tanks, or other receptacles, being water-
tight, or approximately so; valves, and pipe, or pipes, or the like; so arranged and
applied as to allow a portion of the water which it is desired to expel or discharge
from the vessel overboard to enter the then lower compartment, trap, tank, or
other receptacle, by gravitation, and cause it to be retained therein until carried
up by the motion of the vessel to such a level as to allow it to run out, or discharge
overboard from the lower end, also by gravitation; substantially as set forth.
Dated this Sixteenth day of January 1891.
