Improvements in Apparatus for the Ventilation of Water-closets,
Urinals, and such like Places of Convenience.
GEORGE BROWN DAVIS, of Prince's Mews, Great George Street, Westminster,
in the County of Middlesex, Sanitary 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:-
The object of this invention is as the title implies, the ventilation of water-
closets, urinals, &cet., and its purpose is carried into effect by currents of fresh
air being caused to pass through the place where it is employed by means of
its mechanism which is hereunder described and illustrated by the accompanying
drawings.
In the construction of the apparatus which constitutes my invention I use a
combined turbine & air propeller, the propeller being provided with a conduct
pipe the outer end of which is introduced into a main shaft or air passage made
to lead from an upper part of the closet or chamber to a point where the outflow
of air is intended to be exhausted. The turbine is connected with the main
water supply tap by its inlet pipe its outlet forming the supply to the flushing
cistern-the cisterm is provided with a float (connected in the usual way to the
inlet tap) the action of which regulates the supply to the turbine and cistern
in such manner that the simple act of flushing sets the whole apparatus in opera-
tion when the process of ventilation immeadiatly commences as a result of the
united action of the various parts of my invention. And is continued during
the refilling of the cistern-the pressure and passage of the water through the
turbine being the actuating force. Now in order that my invention may be
clearly understood and readily carried into effect I will proceed to further describe
the same with the aid of the accompanying drawings, reference being had to
the letters marked thereon and in which A represents the connection between
the main water supply and the turbine, 13, shews the water-wheel, and C the
fan of the combined turbine and air propeller, 1), is the air inlet and E the
conduct pipe and air outlet from the propeller, F is the main air shaft and G
the pipe which conducts the turbine discharge to the flushing cistern.
H, I, J, K, L, M, presents a view of a popular form of flushing cistern and
accessorries N, O, P, being the tap, float, and their connection, Q is the closet
pan, which is flushed by pulling M which actuates the syphon' arrangement I, J,
causing the flushing cistern to empty its self, whereby, the float O is depressed
and the tap N is opened allowing the water to rush through pipe A to the turbine
giving motion in its course to the water-wheel B, and the air propeller C, finally
returning through pipe G to the cistern.
When the air propeller receives motion in the manner above described a volume
of air is forced through the conduct pipe E and exhausted into the main shaft F,
with force sufficient to induce a strong eduction current in the said shaft I
which immediatly carries any stagnant or vitiated atmosphere to the point of
dispersal and refills the chamber or closet with fresh pure air.

page_text: It will be understood that by suitable arrangement of the water pipes, and
air passages above referred to, a series of compartments or places can be ventilated
at the same time.
Having now particularly described and illustrated the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
(1st.) The utilazation of the pressure of the water (used for flushing and cleans-
ing water-closets, urinals, and such like conveniences) as
a power to drive
mechanical ventilators constructed substantially as herein-before set forth and
described and illustrated in the accompanying drawings.
(2nd.) The peculiar combination of the various parts and mechanism made use
of in the construction of the apparatus which constitutes my invention sub-
stantially as herein-before described and illustrated in the accompanying
drawings.
