I ELIZABETH DEAN, Widow, of
do hereby declare the nature of this
This Invention has for its object a simple and effective arrangement for cooling and
ventilating apartments and buildings in hot climates without interfering with the
light in the interior, and consists as applied to ordinary window openings for example
of an outside screen or jalousie composed of adjustable glass louvres or slats pivotted
at both ends in a frame mounted on hinges or moving in slides for the facility of
opening and closing the jalousie. The framing of this screen is provided at the top
with a finely perforated pipe or trough extending across the frame and supplied with
water by the service pipe or pipes of the building provided with stop cocks, or from
pipes leading from a cistern in the roof which may contain ice to lower the
temperature of the water if desired. The water flows through the perforated pipe
or trough and descends in the form of a thin stream over the outer inclined
surfaces of the several glass slats or louvres the air as it passes between them
being cooled by contact with the water before entering the building-The slats
or louvres being of transparent glass the light in the apartment when the jalousie
is closed is not materially interfered with. The same arrangement of pivotted
glass slats mounted in a frame provided at its upper end with a perforated water
distributer is equally applicable as a ventilating and air cooling skylight when set
at an angle in the roof of a building. The transparent glass slats or louvres may
also be fitted into the panels of doors but when used inside a building the water
would be dispensed with-The adjustment of the angle or opening of the several
glass louvres may be effected by light rods extending across the series of slats to
which they are jointed at each end near the containing frame.

invention to be as follows:-
Should it be found desirable in some cases to subdue the light more or less some of
the slats may be opaque or covered with any opaque material such as woollen cloth
or the like, or some or all of the glass slats may be tinted or stained according to the
light required.

Improvements in Apparatus Applicable to Window Openings,
Skylights, and Doors for Cooling and Ventilating Apartments
and Buildings.
I ELIZABETH DEAN, Widow, of 3 Grove Road Hastings in the County of Sussex
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 :--
This invention has for its object a simple and effective arrangement for cooling and
ventilating apartments and buildings, in hot climates, without interfering with the
light in the interior, and consists as applied to ordinary window openings for example
of an outside screen or jalousie composed of adjustable glass louvres or slats, pivotted
at both ends in a frame, mounted on hinges, or moving in slides, for the facility of
opening or closing the jalousie. The framing of this screen is provided at the top
with a finely perforated pipe or trough extending across the frame, and supplied with
water by the service pipe or pipes of the building, provided with stop cocks, or from
pipes leading from a cistern in the roof, which may if desired contain ice to lower the
temperature of the water. The water flows through the perforated pipe or trough,
and descends in the form of a thin stream or sheet, over the outer inclined surfaces of
the several glass slats or louvres, the air, as it passes between them, being cooled and
moistened by contact with the water, before entering the building. The slats or
louvres being of transparent glass, the light in the apartment, when the jalousie is
closed, is not materially interfered with. The same arrangement of pivotted glass
slats mounted in a frame, provided at its upper end with a perforated water distributor,
is equally applicable as a ventilating and air cooling skylight when, set at an angle in
the roof of a building. The transparent glass slats or louvres may also be fitted into
the panels of doors, but when used inside a building the water would be dispensod
with. The adjustment of the angle or opening of the several glass louvres or slats
may be effected in any convenient manner, preferably by light rods extending
across the series of slats, to which they are jointed at each end near the containing
frame.

attaching them to the pivots.

trough or pipe, provided with perforations on its underside, and supplied with wate

page_text: from any suitable source, by a supply pipe D. E E are light vertical rods connecting
all the slats or louvres A, by means of which they may be opened and shut simul-
taneously, and their angle or inclination adjusted. FF are stop pieces beneath the
lower extremities of the rods E, which prevent them from descending too far, and thus
causing the slats to incline inwards. Any suitable means may be employed for
adjusting and fixing the rods E, but I prefer the arrangement illustrated in figures 1
and 2, where they are shewn as connected at the top by a cross bar G, to which are
attached cords H, passing over a pulley 1, in the fraining, the adjustment being
effected by said cords, which may be secured to an ordinary hook or clip K, con-
veniently placed within reach at the lower part of the frame B.
a a figure 3, are sockets or end pieces, preferably formed of thin metal, which
embrace the extremities of the slats or louvres, and are provided with the pivots a¹.
Upon water being admitted to the perforated trough or pipe C by means of the
supply pipes D, it will flow through the perforations in such trough, over the outer
surfaces of the inclined slats or louvres, in the form of a thin stream or sheet, thus
effectively cooling and moistening the air which passes between said slats into the
apartinent or building to which the apparatus is applied. C¹ (Figure 2) is a
convenient trough or receptacle for collecting the water as it falls from the lowest
slat of the series, which trough may be provided with a suitable discharge pipe D¹.
Where several sets of my apparatus are employed in one building at different levels,
the discharge pipes D¹, of the apparatus at the highest level, may discharge into the.
perforated supply trough or pipe C of the one below, and so on through a series, the
water being finally discharged into a suitable tank or cistern.
In figure 5, which illustrates the application of my invention to doors, 1 have not
shewn it as provided with a perforated trough or pipe for supplying water to flow
over the slats, as such arrangement would not as a rule be convenient, especially in
the case of interior doors, but it will be readily understood that the before described
arrangement of perforated supply pipe C, and receiving trough C³, may be applied to
this arrangement also if desired.
It will also be readily understood that my invention may be equally well applied to
skylights, when set at an angle, though I have not considered it necessary to illustrate
such arrangement in my drawings.
If desired the slats or louvres may be fixed at an angle in the framing in lieu of
being pivotted therein as shewn, in which case the adjusting means would of course
be dispensed with.
Where the framing in which the slats are pivotted is of considerable length from
top to bottom, I prefer instead of employing an unbroken series of slats as shewn in
figure 1, to interrupt the series by a transverse cross bar or bars firmly secured at
each end to the vertical portions of the framing, such cross bar or bars, which may be
made of glass, serving to strengthen the framing.
Should it be found desirable in some cases to subdue the light more or less, some
of the slats may be opaque or covered with any opaque material, such as woollen cloth
or the like, or some or all of the glass slats may be tinted or stained according to the
light required.
In places where there is a plentiful supply of water the perforations in the trough C
may be increased in size and a much larger stream of water permitted to flow
continually over the inclined slats.
My apparatus may be also applied to the window openings of railway carriages, and
in the form of a sloping skylight to the roofs thereof, the water being supplied from a
convenient tank or tanks carried on the top of one of the carriages.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
