I, CHARLES KITE of 31 Baronsmere Road, East Finchley, Engineer do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to render smoke and other ventilators more effective
by preventing all leakage of smoke or draught therefrom and rendering the action of
the same perfectly noiseless.
This I effect by fitting a ventilator with a highly sensitive valve mounted on an
oscillating frame eccentrically hung, so that the ventilator is opened or closed by the
slightest up or down draught and when closed lays so perfectly flat against the face
plate of the ventilator as to render the latter absolutely smoke and draught tight.

page_text: I CHARLES KITE of 31 Baronsmere Road East Finchley 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 to render smoke and other ventilators more effective 5
by preventing all leakage of smoke or draught therefrom and rendering the action of
the same perfectly noiseless and automatic.
DESCRIPTION.
To carry out my invention I fit a ventilator with a highly sensitive valve (a) made
of oil silk mica or any other suitable substance or material mounted on an oscillating
frame (b) eccentrically hung a little out of the perpendicular on brackets (c) fixed to
the sides of the box or casing (d) which encloses the apparatus.
The bottom of the frame (b) is fitted with a counterpoise bar (e) or its equivalent
which regulates the action of the frame and serves to restore it to its normal position
when the air current ceases to act thereon-The front of the box or casing is fitted
with a perforated plate (f) or with a frame having suitable openings formed therein―
This perforated plate or frame forms the seating for the valve plate or valve plates-
A stop (g) faced with rubber or other suitable material is fixed in or formed on the
top of the casing (d) to prevent the frame (b) being thrown too far out of position.
When using a frame to form the valve seating and employing mica or other rigid
substance or material for the valve I prefer fitting each of the openings in such
frame with a separate mica or other plate so as to ensure the plates fitting closely
against the seating and if necessary or desirable I face the frame forming the seating
with rubber or other suitable material or substance-My improved automatic silent
valve is so extremely sensitive and so accurately adjusted that it is opened or closed
by the slightest up or down draught and when closed it lies so perfectly flat against
the perforated plate or frame as to render the latter both smoke and draught tight-
It is likewise perfectly noiseless in its action-When desired I fit the front of the
ventilator with a screen plate of any suitable design and material which serves to
conceal the perforated plate Or the latter may itself be made of any suitable
ornamental design.
