PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cleaning the Bottoms of Ships, or
for Removing therefrom Barnacles and other Foul Matter.
I, GEORGE STUART SCORER, Smith's Dock, North Shields, Dockyard
Manager do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in apparatus for cleaning the bottoms of
ships, or for removing therefrom, barnacles and other foul matter, when such
vessels are in dry dock, or under similar circumstances, and has for its object to
provide a portable apparatus that shall be more effectual in operation than those
means heretofore and at present employed for the above purpose.
In carrying out my invention, I employ a number of revolving brushes or
scrubbers working upon one or more spindles, which brushes or scrubbers are
driven by means of a portable electric-motor, flexibly connected in any well-known
manner with a dynamo for supplying the necessary power.
Dated this 23rd day of October 1894.

Improvements in Apparatus for Cleaning the Bottoms of Ships, or
for Removing therefrom Barnacles and other Foul Matter.
I, GEORGE STUART SCORER, Smith's Dock, North Shields, Dockyard
Manager, 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 improvements in apparatus for cleaning the bottoms of
ships or for removing therefrom barnacles and other foul matter, when such vessels
are in dry dock, or under similar circumstances, and has for its object to provide a
portable apparatus that shall be more effectual in operation than those means
heretofore and at present employed for the above purpose.
In carrying out my invention, I employ a revolving brush, or scrubber, or
revolving brushes or the like, fastened on a spindle which also forms the spindle to
which the armature of a portable electro motor is attached.
The motor is connected by a flexible conductor with a dynamo or other source
of electricity. The spindle of the motor passes through the end of a rectangular
framing to which are attached the magnets of the motor and also the handles for
holding the apparatus when in action.
On the accompanying drawing I have shown an apparatus with two brushes, but
a similar application can be used with a lesser or greater number of brushes
fastened on the spindle.
Fig. 1, is an elevation, Fig. 2 a plan, and Fig. 3 an end view of an apparatus
constructed in accordance with my invention.

page_text: a a are two brushes or scrubbers.one at each end of the spindle b. The spindle
is supported near each end in the rectangular framing c and carries at or about the
centre of its length an armature d, which, together with the magnets e form part
of the electro motor which may be of any form and construction.
The terminals f and gare connected by flexible connections with any suitable
source of electricity. Two handles h.are provided for holding the apparatus when
at work.
The motor may have any suitable switch for applying and shutting off the
current. The apparatus is used by holding it by the handles h, and pressing the
brushes or scrubbers against that part of the vessel which is to be cleaned, and on
connecting the motor with a source of electricity, the brushes or the 'like revolve
or clear away any adherent material on any part of the ships surface.
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;
In apparatus for cleaning the bottom of ships or for removing therefrom
barnacles and other foul matter, the combination of a portable electro motor of
any suitable construction, with a brush, scrubber or the like, or with brushes,
scrubbers or the like fastened to the spindle of the armature of the said electro
motor, the whole substantially as and for the purposes described in the above
Specification, and exemplified on the accompanying drawings.
