PROVISIONAL SPECIFICATION.
An Improved Brush.
I, JOHN LAIDLAW, of 12 Bruce Road, Pollokshields, Engineer do hereby
declare the nature of this invention to be as follows:
This invention relates to an improved brush actuated by mechanical means
applicable for cleaning ships' decks, carriages, for use in baths, and for other
similar purposes. It may also be used for painting large surfaces, such as the
hulis of ships, bridges, or other articles. The brush is a revolving one driven by
proper mechanical means contained inside the outer casing of the brush. In
carrying out my invention I provide inside the casing of the brush a turbine or
other small engine driven by the water for communicating the motion through
proper gearing to the brush. The brush may be made of any suitable material
for the particular object to which it is to be applied. The water after having
done its work in driving the engine is conducted to the brush proper, where by
centrifugal action it is forced in among the bristles of the brush, and from thence
to the surface to be cleaned. When used for painting the brush may be actuated
by compressed air, electro motor, or other suitable appliance and a regulated
supply of paint may be fed on to the brush by a separate pipe of suitable size.

COMPLETE SPECIFICATION.
An Improved Brush.
I, JOHN LAIDLAW, of 12 Bruce Road, Pollokshields, North Britain, Engineer,
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 an improved brush actuated by mechanical means
applicable for cleaning ships' decks, carriages, for use in baths, and for other
similar purposes. It may also be used for painting large surfaces such as the
hulls of ships, bridges or other articles. The brush is a revolving one driven by
proper mechanical means contained inside the outer casing of the brush. In
carrying out my invention I provide inside the casing of the brush a turbine or
other small engine driven by the water for communicating the motion through
proper gearing to the brush. The brush may be made of any suitable material
for the particular object to which it is to be applied. The water after having
done its work in driving the engine is conducted to the brush proper, where by
centrifugal action it is forced in among the bristles of the brush, and from thence
to the surface to be cleaned. When used for painting, the brush may be actuated
by compressed air, electro-motor, or other suitable appliance, and a regulated
supply of paint may be fed on to the brush by a separate pipe of suitable size.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended two explanatory sheets of drawings in the
several figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a vertical section of the brush.

page_text: Figure 3 is a perspective view of the brush as it is to be used for washing
decks.
The brush has a hollow handle which is connected to the water supply. The
water enters the brush at A, passes on to a small turbine BB which it drives
round at a rapid rate. Attached to the axle of the turbine there is a pinion C
which gears into a toothed wheel DD. The axle of the toothed wheel DD carries
a pinion E, which gears into the interior teeth of the ring FF. This ring F F
carries the brush & G, which is thus kept revolving while the water is running.
The water after leaving the turbine passes down the passage H, and by
centrifugal action is driven out among the bristles of the brush.
When the brush is used for a bath, A would represent the supply pipe, and the
brush would be fixed to the side of the bath by the flange 1 I.
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 :-
A rotary brush actuated by the water to be used for washing constructed sub-
stantially as described and illustrated on the accompanying sheets of drawings.
