PROVISIONAL SPECIFICATION.
Improvements in or relating to the Mechanical Propulsion of Steam
Ships and the like.
I, WILLIAM BRUCE THOMPSON, of Ellangowan, Dundee, in the County of
Forfar, N.B. Engineer, do hereby declare the nature of this invention to be as
follows:-

This invention relates to Improvements in or relating to the Mechanical
Propulsion of Steam Ships and the like, the object being to ensure some means of
propulsion, should a break-down occur.
Existing vessels are generally propelled by means of either paddle wheels, or
screws, and generally speaking should the engine break down, the vessel has to

provided with twin screws, and where each screw is driven by a separate engine,
then if one engine should break down, the other will be still available.
In carrying out my invention, I provide the vessel with paddle wheels, and also
with two or more screw propellers, all being driven in known ways and so, should
a break-down occur, the chances are, that either the paddle wheels or one or
all of the screws would still be available.

are provided with twin screws, and where each screw is driven by a separate
engine, then if one engine should break down, the other will be still available.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings, showing in side elevation a vessel as
fitted with my improvements.
In carrying out my invention, I provide the vessel with paddle wheels W. and
also with two or more screw propellers S. P.-in the drawing the vessel is shown
provided with one pair of paddles and with two screws-all being driven in known
ways and 50, should a break-down occur, the chances are that either the paddle
wheels or one or all of the screws would still be available.

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) In a vessel propelled by mechanical means, the combination of a pair of
paddle wheels with twin screws, substantially as described.
(2) In a vessel propelled by mechanical means, the combination of a pair of
paddle wheels with three or more screws, substantially as described.
(3) In a vessel propelled by mechanical means, the combination of two or more
pairs of paddle wheels with two or more screws as described.
