IMPROVEMENTS IN VENTILATORS FOR BUILDINGS
Year: 1885

page_text: I, GEORGE SOWERBY of the Gateshead Stained Glass Company, Gateshead in
the County of Durham, Glass Manufacturer do hereby declare the nature of my
said Invention for "IMPROVEMENTS IN VENTILATORS FOR BUILDINGS" to be as
follows:-
The object of my Invention is to provide ventilators for buildings which will
not constitute any material obstruction to the passage of light through windows
and which will be watertight.
According to my Invention I form an orifice and a spout or funnel in a pane of
glass which is inserted in the window or other part of the building. Spouts or
funnels thus formed when situated at the exterior of the building are turned
downwards and when they are situated inside they are turned upwards so as in
both cases to keep out rain. The covers or flaps which are arranged in proximity
to the orifices of these spouts or funnels for preventing direct draught are also
of glass so that the whole apparatus, thus arranged constitutes practically no
impediment to the light when used in windows or the like, and when used in walls
or the like will itself form a means of admitting light to the apartment which it is
used to ventilate.

page_text: I GEORGE SOWERBY of Gateshead in the County of Durham 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 my Invention is to provide ventilators for buildings which will
not constitute any material obstruction to the passage of light through windows
and which will be watertight. I will describe my Invention with reference to the
accompanying drawings.
According to my Invention I form an orifice and a spout or funnel A in a pane
of glass B which is inserted in the window or other part of the building to be
ventilated. Spouts or funnels thus formed when situated at the exterior of the
building should be turned downwards as shewn in Figure 1 and when they are
situated inside they should be turned upwards as shewn in Figure 2 so as in both
cases to keep out rain. Covers or flaps C may be arranged by hinging or otherwise
in proximity to the orifices of these spouts or funnels for preventing direct draught,
and may be provided with a strut or any suitable arrangement for adjusting them
and fixing them in their adjusted position They also should be of glass so that
the whole apparatus thus arranged constitutes practically no impediment to the
light when used in windows or the like and when used in walls or the like will
itself form a means of admitting light to the apartment or place which it is used to
ventilate.
The apparatus singly or in numbers may be fixed in any suitable position for
example some at a low level for inlet and some at a high level for exit of the air
and one or several orifices and funnels as desired may be formed in and on each
piece of glass and the funnels may be of any suitable shape adapted for the purpose
for example they may be turned upwards and downwards.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed I declare that what
I claim is
A ventilator consisting of a pane or piece of glass with an orifice and funnel or
orifices and funnels formed therein and thereon substantially as and for the
purpose described whether having in combination therewith or not a cover or flap
all substantially as hereinbefore described.
