HENRY THOMAS JOHNSON of Willow Bank Urmston near Manchester in the County
of Lancaster Sanitary Surveyor do hereby declare the nature of this invention to be
as follows:-
The object of my Invention is to supply or extract air by means of fans attached to
a waterwheel and forming part thereof, for the purposes of Ventilation.
For this purpose I construct an ordinary waterwheel of any dimensions and of any
ordinary form to the side or sides of which and upon an extension of the same axle
so forming a part of the wheel. I attach blades or fans, the waterwheel with the fans
is enclosed within a case with tubes and openings, respectively for the inflow and the
outflow of air the wheel may be worked with water from any suitable source and in
the forms generally known as overshot undershot or breast, but preferably I use the
overshot.
The revolving of the fans will according to the water power create a corresponding
motion and suction of the air, and may be used either to draw air from rooms or
compartments of Buildings, Ships or Mines and discharge the same where convenient,
or may be used for drawing the air from the outside atmosphere and delivering the
samme into the said rooms or compartments of Buildings Ships & Mines.
The tube or case will also be provided with an outlet for the waste water from the
waterwheel.
Or for small Ventilating tubes, the buckets of the waterwheel may be so extended
in a radial form from the wheel as to act as fans instead of attaching the fans to the
sides of the wheel as heretofore stated.

what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:
The object of my Invention is to supply or extract air by means of Fans attached
to or forming part of a waterwheel for the purposes of Ventilation.
For this purpose I construct an ordinary waterwheel or paddle wheel of any
dimensions, the paddles or blades forming also the blades of the fan, they being
identical.
The wheel with its blades or fans is enclosed within a case or tube with arms for the
inflow & outflow of air. The wheel to be worked by a jet of water impinging at high
pressure upon the said blades.
The tube or case will also be provided with an outlet for the effluent water.
The revolving of the wheel or fans will according to the waterpower create a
corresponding motion and suction of the air and may be used either to draw air from
rooms, or compartments of Buildings, ships or Mines and discharge the same where
convenient or may be used for drawing the outside atmosphere and delivering the
same into the said rooms or compartments of Buildings, ships and mines.
Having now particularly described the nature of my Invention I declare that what
I claim is
The withdrawal or supply of air by means of the current set up by the revolving
of a waterwheel with fans set in Motion by a high pressure of water.
