Improvements in Apparatus for Unloading and Loading Oil-carrying
Vessels.
I, RICHARD DUDLEY, of The Anglo American Oil Company Limited, Billiter
Street, in the City of London, Superintendent of Construction, 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 :-
My invention relates to apparatus for loading and unloading oil carrying vessels
as I shall describe referring to the accompanying drawings..
Fig. 1 is a side elevation, Figs. 2 and 3 are respectively an end view and a
plan of the jointed pipes, Fig. 4 is a section of one of the joints and Fig. 5 is
a section of the sluice check valve.
On a truck A that can be run along a quay, I mount a derrick B carrying a
pipe C which is made in a number of sections jointed to each other with stuffing
boxes D so as to allow movements of these sections in all directions vertically and
horizontally. The truck A. is brought to the side of a steamer or other vessel
carrying oil, and one extreme section of the jointed pipe is connected to the
discharge pipe of the pump usually employed in such vessels for discharging oil from
their tanks. The other extreme section of the jointed pipes being connected to a
horizontal pipe extending along the quay, and this pipe being temporarily con-
nected to a main pipe H leading to the oil reservoirs which may be at a distance,
the pump on board the vessel is worked, drawing oil from the tanks on board the
vessel and delivering it to the reservoirs, through the jointed pipes, which allow of
the movements of the vessel due to waves or tides. In like manner, when the tanks
of a barge or other vessel have to be charged with oil, the jointed pipes are con-
nected to the main pipe from the reservoirs which are elevated so that oil flows from
them, or, when they are not elevated, the oil may be forced by a pump into the
tanks.
In the pipe leading to the reservoirs I provide a sluice check valve S such as is
shown in Fig. 5, preferably also an ordinary shut off valve E. Within the casing S
there is fitted a sluice consisting of a flap door F jointed to a stem G which can be
raised and lowered by a screw. When the stem G is lowered, the flap lies against
the face of the opening, free to move away from it and let Huid pass in the one
direction to the reservoirs but closing the opening against passage of the fluid in the
opposite direction back to the vessel.
When however the fluid has to flow back from the reservoirs to the vessel, the
stem G and door F are raised so that the opening is uncovered, giving free passage
to the fluid backwards. The valves S and E are situated in a covered pit, and the
main pipe H is led underground so as not to interfere with traffic on the quay.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. For unloading or loading an oil carrying vessel, a derrick truck and a set of
pipes having joints allowing movements in all directions to connect tanks in the
vessel with a vive leading to reservoirs on shore, substantially as described.

page_text: 2. In combination with the set of pipes above referred to, a sluice check valve,
substantially as and for the purpose set forth.
