PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Propulsion, Stopping, Steering,
and Handling of Navigable Vessels.
We, ROBERT RANKIN and ROBERT DUNCAN, both of the firm of Ross &
Duncan, Engineers, Whitefield Works, Govan, Lanarkshire, do hereby declare the
nature of this invention to be as follows
This invention relates to improved apparatus for directing water jets to be used
as auxiliary means for propelling, stopping and steering navigable vessels more
especially such as are used for towing and salvage purposes, and for connected
apparatus for handling the said vessels."
Under the invention the vessel's engines are provided with circulating pumps of
exceptional power, or, as is preferred, separate pumping engines are used for
circulating the water through the condenser tubes, by forcing or sucking, but
preferentially by sucking the water through the condenser and forcing it through a
pipe extending fore and aft of the vessel and terminating in a pipe or pipes
preferably at or near the bows at which point or points nozzles pipes or other
directing apparatus are connected to said pipe or pipes to direct the issuing water
as may be desired. The nozzles or ends of the pipe or pipes, are in general, made
so as to direct the outflowing water and sluice or other valves fitted in the pipe or
pipes, and controlled by a hand lever are provided to direct the water by the
outlets on either the port or starboard sides, or ahead or astern, in order to effect
the steering or slewing round of the vessel especially when there is no way on the
vessel and the ordinary rudder or steering gear is unserviceable. Or the pipes and
outlets may be so constructed and jointed as to permit of varying the direction of
outflow of the jets so that their force may be utilized as auxiliary means of
propulsion or for stopping the vessel as well as for steering. In conjunction with
the pumping engines suitable valves and nozzles are provided to permit of drawing
the water from submerged vessels for salvage purposes and for directing water
through hose for extinguishing fires.
The auxiliary engine for working the pump may also be used to drive a warping
end or ends on or above the deck, for the speedy and efficient handling of ropes and
hawsers.

Improvements in Apparatus for the Propulsion, Stopping, Steering,
and Handling of Navigable Vessels.
We, ROBERT RANKIN and ROBERT DUNCAN, both of the firm of Ross &
Duncan Engineers, Whitefield Works, Govan, Lanarkshire, 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 :-
This invention relates to improved apparatus for directing water jets to be used
as auxiliary means for propelling, stopping and steering navigable vessels, more
especially such as are used for towing and salvage purposes, and for connected
apparatus for handling the said vessels.
As represented in the accompanying drawings at Figures 1 and 2 which show a

page_text: vessel divided amidship for convenience of representation to as large a scale as
possible, the vessel's engines A are provided with circulating pumps of exceptional
power, or as is preferred, separate pumping engines B are used for circulating the
water through the tubes of the condenser C by forcing or sucking, but preferentially
by sucking the water through the condenser C and inlet D and forcing it through
pipes E E extending fore and aft of the vessel and terminating in a pipe or
pipes F F preferably at or near the bows at which point or points nozzles pipes ff¹
or other directing apparatus are connected to said pipe or pipes to direct the
issuing water as may be desired. The nozzles or ends of the pipe or pipes are in
general, made so as to direct the outflowing water, and sluice or other valves G
fitted in the pipe or pipes, and controlled by a hand lever are provided to direct the
water by the outlets on either the port or starboard sides, or ahead or astern, in
order to effect the steering or slewing round of the vessel especially when there is
no way on the vessel and the ordinary rudder or steering gear is unserviceable.
separate pipe F2 as shown at Figures 1 and 3 is provided and used for driving the
vessel astern and also a pipe E' for driving ahead these pipes being provided with
valves e e¹ for controlling the direction of flow of the water ejected by the pumps.
A separate inlet pipe may also be provided to permit of the pumps drawing water
direct instead of through the condenser. The pipes F F and outlets ff may be
so constructed and jointed as to permit of varying the direction of outflow of the
jets so that their force may be utilized as auxiliary means of propulsion or for
stopping the vessel as well as for steering. In conjunction with the pumping
engines suitable valves and nozzles may be provided to permit of drawing the
water from submerged vessels for salvage purposes and for directing water through
hose for extinguishing fires.
A
The auxiliary engine for working the pump may also be used to drive a warping
end or ends on or above the deck for the speedy and efficient handling of ropes and
hawsers.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
The arrangement and combination of parts constituting the improved water jet
apparatus, hereinbefore described with reference to the annexed drawings for use
as auxiliary means for propelling, steering and stopping navigable vessels.
