Improvements in Submarine Vessels.
We. WILLIAM CAMPER STOREY, of 13, Regent Street, in the County of Middlesex,
Naval Architect, and GRAYDON POORE, of 49, Queen Victoria Street, in the City of
London, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
In some submarine vessels there is provided a chamber furnished with ingress and
egress doors to permit of a diver, suitably equipped, passing from the interior to the
exterior of the vessel for the purpose of effecting some desired operation. For this
purpose the diver enters the chamber when it is empty, and after securely closing the
ingress door, water is admitted to the chamber so as to fill it. The diver then opens
the egress door and passes to the exterior of the vessel. The admission of water to the
chamber alters the buoyancy of the vessel and consequently its depth of immersion,
thereby rendering the operations of a diver difficult to perform.
Now the object of this invention is to overcome these disadvantages. To this end
we employ a pump or equivalent means so constructed and operated that it discharges
water overboard from the ballast tanks of the submarine vessel at the same rate as it
is admitted to the diver's chamber. By this means the weight and buoyancy of the
vessel remain unaltered and its depth of immersion is kept constant.
According to one method a double acting pump is used one part throwing water
from a ballast tank overboard, and another delivering water from the sea into the
divers chamber. If the water be admitted direct from the sea to the diver's chamber
the latter may be provided with a gauge or index to show at what rate it is being
filled, so that the pump may be worked at a corresponding rate, or the gauge
indicating the depth of the boat below the surface may be used for this purpose. It
will be evident that the invention may be carried into effect in many different ways
without departure from its essential principle.

Naval Architect, and GRAYDON POORE, of 49, Queen Victoria Street, in the City of
London, Civil Engineer, 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 :—
In some submarine vessels there is provided a chamber furnished with ingress and
egress doors to permit of a diver, suitably equipped, passing from the interior to the
exterior of the vessel, for the purpose of effecting some desired operation. For this
purpose, the diver enters the chamber when it is empty, and after securely closing the
ingress door, water is admitted to the chamber so as to fill it. The diver then opens
the egress door and passes to the exterior of the vessel. The admission of water from
the exterior of the vessel to the chamber alters the buoyancy of the vessel and
consequently its depth of immersion, thereby rendering the operations of a diver
difficult to perform.
Now the object of this invention is to overcome these disadvantages. To this end
we employ a pump or equivalent means so constructed and operated that it discharges
water from the ballast tanks of the submarine vessel at the same rate as it is admitted
to the diver's chamber. By this means, the weight and buoyancy of the vessel
remain unaltered and its depth of immersion is kept constant.
According to one method, a double acting pump is used, one part throwing water
from a ballast tank overboard, and another delivering water from the sea into the
diver's chamber. It will be evident that the invention may be carried into effect in
many different ways without departure from its essential principle.
The accompanying drawing illustrates in vertical section part of a submarine vessel
embodying our improvements.
I is a diver's chamber provided with an ingress door 2 and with an egress door 3.
3* is a seating of suitable material such as india rubber, to effect a tight joint between
the top of the vessel and the door 3. 4 is a cock or valve by which air may escape
during the filling of the divers chamber 1 with water. 5 is a water hallast tank or
chamber. 6 is a double acting pump provided with suction and delivering pipes 7
and 8 respectively for throwing water from the ballast tank or chamber 5 overboard
and with suction and delivering pipes 9 and 10 respectively for delivering an equal
quantity of water from the sea to the divers chamber i. By this means the chamber 1
may be filled with water to enable the diver to pass to the exterior of the boat,
without materially affecting the weight or buoyancy of the latter. 11 is a ladder to
enable the diver to gain access to the chamber 1. 12 is a pipe connecting the divers
chamber 1 with the ballast tank 5; it is provided with a cock or valve 13 by opening
which the water in the divers chamber may, when necessary, be allowed to flow into
the ballast tank 5.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
The arrangement of a pump in connection with the divers egress chamber and
with the exterior of the vessel and with the ballast chamber in such a manner that
water from without the vessel can be delivered into the divers egress chamber and
simultaneously water in like quantity from the ballast chamber can be discharged
from the vessel substantially as described.
