1 JAMES WING of 50 Gordon Road, Charlton, Kent Engineer do hereby declare the
nature of this invention to be as follows:
My Invention consists in the application of Pneumatic Apparatus to Ships Fittings;
Condensed Water-tanks; and to Ballast-Tanks whereby the water-ballast can be
discharged or admitted for the Trimming of the Vessel.
In lieu of the present water-pumps and their costly appliances I substitute one or
more air-compressors fixed in a convenient position or positions whereby I apply
pneumatic pressure to the working of the Ships Fittings; the supply and aeration of
the condensed water; and also by driving air at a pressure on to the top surface
of the water-ballast it is expelled by the Kingston or other valves and openings; or
by reversing the air-compressor or compressors or air-pumps or machines a vacuum
is formed whereby the influx of water to any desired extent is induced into the ballast
tank or compartment.
Dated this Thirteenth day of March 1888.

Samuel Joseph Mackie.

I JAMES WING of 97 Charlton Lane, New Charlton in the County of Kent (late of
50 Gordon Road Charlton) Engineer, do hereby declare the nature of my said inven-
tion and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
By the combination of pneumatic apparatus with Ships Fittings condensed Water
Tanks and the Ballast Tanks, the water supply can be put under pressure or exhaust;
the water-ballast tanks can be filled or ejected to any extent required and the various
duties hitherto performed by the pumps and fans can be performed with superior
effect.
In lieu of the present water pumps and their costly appliances I substitute one or
more air-compressors air-pumps or other similar pneumatic machines fixed in a
convenient position or positions whereby I apply pneumatic pressure to the working
of the Ships fittings, the supply and aeration of the condensed water and also by
driving air at a pressure on the surface of the water-ballast it is expelled by the
.Kingston or other valves and openings; or by reversing the air-compressor or
compressors or air pumps or other pneumatic machines a vacuum is formed, whereby
the influx of water to any desired extent is induced into the ballast or water tanks or
other compartment, pipes or fittings.
The pneumatic apparatus so applied to the water service of the Ship can also be
used for expelling or exhausting petroleum or other gases or foul air arising from
cargoes or other sources.
In the accompanying drawings Fig. 1 represents the longitudinal section of a cargo
vessel, with the combination of the air compressor with the Ships fittings and tanks
.&c. C. is the air compressor; A A A A A are the air conveying pipes in connection
therewith B. T is the water ballast tank and D D D D are the discharge pipes for
the air when it is desired to diminish the pressure and to allow water from the exterior
of the hull to enter, K. is the Kingston valve C. H. C. H. are the cargo holds, and
V. V. V the ventilators T. the freshwater or condensed water tanks.
Fig. 2. is the longitudinal section of a Passenger Cattle and Cargo Vessel similarly
fitted with air compressor, C. from which the air conveying pipes A A A A proceed.
B. T. B. T. are the water-ballast tanks FW FW F W the pipes conveying the fresh-
water supply under pressure throughout the Ship. C. H. C. H. C. H. C. H. are
the cargo holds. D. D are the air discharge pipes from the ballast-tanks for the
admission of water.
Fig. 3 is a section of the air compressor C, in which S is the steam cylinder;
and A. the air cylinder; S being the suction pipe and D. the delivery pipe.
By connecting as in Fig. 2. at G the air pipes A. A. with the cargo hold C. H.
any foul air or gases therein can be exhausted or expressed either with or without
connection also with the discharge pipes D. D.

page_text: 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) The combination of one or more air compressors air pumps or other similar
pneumatic apparatus with the Ships Fittings, condensed water tanks, the water ballast-
tanks the hold or other compartments pipes and services heretofore actuated and
worked by pumps substantially as described.
(2) The use of the said combination of pneumatic apparatus with the Ships fittings
tanks and otherwise for the purpose of expelling or exhausting petroleum and other
gases or foul air arising from cargoes or other sources substantially as described.
