It consists of a shaft of any diameter or size and may be either square or round
and of any material-At any convenient point in the Shaft a deflecting guard is
attached to the interior of the Shaft to shoot off any water which may have
entered the Ventilator above and direct it to the opposite side of the shaft which
at this point sweeps out in a semicircular or any less curve and again slightly rises
so as to form a hollow at the bottom of the curve the shaft then continues on as
shewn in the diagram marked 5 the hollow bottom of the shaft is swung on a
spindle marked A on the diagram with a counterpoise marked B-any water
descending the shaft is then shot off by the deflecting guard into the hollow
bottom marked C: the weight of the water overpowering the counterpoise opens
the valve D, the water falls out on to the deck or roof as arranged and the
counterpoise brings the valve back to its place.

"IMPROVEMENTS IN APPLIANCES FOR PREVENTING THE
PASSAGE OF WATER DOWN VENTILATING SHAFTS ON SHIPBOARD AND IN
BUILDINGS
"
My improved appliance or apparatus for providing a safeguard against the
passage of water down ventilating shafts on shipboard and in buildings occupying
much less space than the contrivances at present in use to effect that object and
permitting of the passage of much more air than any of them and called "the
Eolus waterproof ventilating shaft" is represented in one of its forms by the
annexed drawings which show an elevation and a vertical section.
It consists of a shaft of any diameter or size and may be either square or round
and of any material. At any convenient point in the shaft a deflecting guard is
attached to the interior of the shaft to shoot off any water which may have
entered the ventilator above and direct it to the opposite side of the shaft which
at this point sweeps out in a semicircular or any less curve and again slightly rises
so as to form a hollow at the bottom of the curve the shaft then continues on as
shown. The hollow bottom of the shaft is swung on a spindle marked A with a
counterpoise marked B-any water descending the shaft is then shot off by the
deflecting guard into the hollow bottom marked C. The weight of the water
overpowering the counterpoise opens the valve the water falls out on to the deck
or roof as arranged and the counterpoise brings the valve back to its place.
What I claim is the combination with a ventilating shaft of an automatic water
discharging mechanism substantially as described.
I also claim the improved ventilating appliance or apparatus substantially as
described and illustrated by the annexed drawings.
In witness whereof I the said Richard Oakley have hereunto set my hand
and seal this Twelfth day of October in the year of our Lord One thousand eight
hundred and eighty three.
