My Invention relates to apparatus which is worked by means of water under
pressure, and has for its object to purify, moisten; and cool or warm the air of
dwelling and other rooms, theatres, churches, and other buildings.
The apparatus consists of two chambers, one within the other, the inner one being
open at each end and communicating with the outer one at the bottom, and a space
being formed between the two chambers. At the upper part of the apparatus water
under pressure entering by a pipe is admitted through a nozzle in finely divided
streams into the top of the inner chamber into which also air is free to enter
through apertures or passages over the open top. At the bottom of the said outer
chamber is fitted a pipe to carry off waste water, and at the top a chamber with a
cap or cover, perforated at the top to serve as a distributor. To the under side of
this distributor chamber is fastened the said nozzle to produce a spray by water
being forced through it.
The water ejected and spurting from the nozzle with great force fills the said
inner chamber with a finely divided spray of water which is caused to act in a
downward direction like a continuous plunger carrying along the air contained in
the said inner chamber and drawing thereinto air, gases, or vapours from the room
or building through the passages made for the purpose. When this mixture of air
and water spray has reached the lower part of the said outer chamber, the purified
and cooled air is separated from the water, pressed upward, and escapes through

" IMPROVE-
HEINRICH MESTERN, of Berlin, Prussia, in the Empire of Germany.
MENTS IN APPARATUS FOR VENTILATING, COOLING, AND WARMING BUILDINGS AND
ROOMS."
My Invention relates to apparatus which is worked by means of water under
pressure, and has for its object to purify, moisten, and cool or warm the air of
dwelling and other rooms, theatres, churches, and other buildings.
The apparatus consists of two chambers, one within the other, the inner one
being open at each end, and communicating with the outer one at the bottom, and
a space being formed between the two chambers. At the upper part of the
apparatus water under pressure entering by a pipe is admitted through a nozzle in
finely divided streams into the top of the inner chamber, into which also air is free
to enter through apertures or passages over the open top. At the bottom of the
said outer chamber is fitted a pipe to carry off waste water, and at the top a
chamber with a cap or cover, perforated at the top to serve as a distributor.
To the underside of this distributor chamber is fastened the said nozzle to
produce a spray by water being forced through it.
The water ejected and spurting from the nozzle with great force fills the said
inner chamber with a finely divided spray of water, which is caused to act in a
downward direction like a continuous plunger, carrying along the air contained in
the said inner chamber, and drawing thereinto air, gases, or vapours from the room
or building through the passages made for the purpose. When this mixture of air
and water spray has reached the lower part of the said outer chamber the purified
and cooled air is separated from the water, pressed upward, and escapes through
the holes in the distributor into the room or building required to be ventilated and
cooled. For warming, hot water is to be used instead of cold.

The
The said nozzle may be either an ordinary rose head or it may be constructed as
follows-To the bottom of the distributor is secured, as the terminus of the water
supply pipe, an elbow with a hanging branch, to which is screwed the spray nozzle.
The lower or bulb-shaped part of this nozzle has a rim, which is again contracted a
little. The surface of the hole produced thereby is conical, fitting closely to an
annular neck of a core pipe, the outer surface of the neck being also conical.
core pipe screwed into the upper part of the nozzle is open at its upper end, and
furnished with openings in that part which passes through the enlarged part of the
nozzle. The lower end of the core pipe is closed by a screw cap or otherwise. In
the conical surface of the said neck fine grooves are milled in the direction of
from the top of the truncated cone to the base thereof. The water admitted
through the said openings in the enlarged part of the nozzle will be caused to
spurt through the grooves formed in the neck in a divergent direction, and thereby
produce a very fine and forcible spray, with a minimum of water consumed.
When the apparatus is used in a kitchen in order to get rid of moisture and
moist vapours the waste pipe at the bottom of the apparatus is made to lead down
into a sink, and there is a pipe connected to the upper part of the apparatus,
through which the drawn off air and vapours can pass into the chimney.
Having thus stated the nature of the said Invention I will proceed to describe
more particularly in what manner the same is to be performed by the aid of the
accompanying Drawings, in which are represented the parts of apparatus above
referred to.

page_text: DESCRIPTION OF THE DRAWINGS.
In Sheet I. Fig. 1 is a vertical section of the apparatus; Fig. 2 is a horizontal
section, Fig. 3 is an elevation, and Fig. 4 a plan or horizontal view of the same.
The cylinder C, open at the lower end, is fixed concentrically on and into the
larger cylinder A, the bottom of which is hollowed out, as shewn. The annular
space E between the two cylinders A and C forms the air passage which leads to
the air distributor K on the top of the apparatus, through the perforated cover D
of which the air passes into the room, or into a draft pipe leading off the bad gases
of dwelling rooms, or the vapours of a kitchen into the open air or into a
chimney.
The interior of the cylinder C forms the spray chamber communicating at the
lower end with the air passage E, and at the upper end with the air openings F
under the bottom of the distributor K, to the underside of which is fixed the spray
nozzle H, which may be of either common or peculiar construction, receiving water
under pressure from the supply pipe P, and discharging it in the form of a diverging
cone against the inside walls of the cylinder C. By the force of the water it is
deflected from the walls of the cylinder C against the opposite walls, whence it
drops down to the bottom B of the cylinder A, a portion of the water falling down
directly to the bottom B, and being carried off by the waste pipe Q.
The working of the apparatus is as follows:-The water ejected and spurting
from the nozzle H with great force fills the cylinder or chamber C with a very
finely divided spray of water, which acts in a downward direction like a continuous
plunger, carrying along all the water contained in the cylinder or chamber C, and
drawing in air, gases, or vapours through the openings T. When this mixture
of air and water in a state of spray has reached the lower part of the cylinder or
chamber A, the purified and cooled air becomes separated from the water, is pressed
upwards, and escapes through the apertures in the top of the distributor K.
When warmed air is required to be distributed, hot water is used instead of
cold.
The above mentioned nozzle H may be of a common and simple construction, as
shewn in Fig. 5, in which the bottom of a hollow cone is provided with a ring of
fine holes bored in an oblique diverging direction, but it is preferred to use a nozzle
of peculiar construction, as hereinafter described.
To the bottom of the distributor is secured as the terminus of the water supply
pipe P an elbow with a hanging branch, to which is screwed the spray nozzle H,
which is represented in Sheet II., in which Fig. 1 is an elevation, and Fig. 2 a
vertical section. The lower or bulb shaped part of the nozzle has a rim, which is
again contracted a little. The surface of the opening produced thereby is conical,
fitting closely to an annular neck S of the core pipe R, the outer surface of such
neck being also conical.
The core pipe R screwed into the upper part of the nozzle H is open at its upper
end, and furnished with openings T in that part which passes through the enlarged
part of the nozzle H. The lower end of the core pipe R is closed by a screw cap,
as shewn, or otherwise.
In the conical surface of the neck S fine grooves of semicircular section are
milled in the direction of from the top of the truncated cone to the base thereof.
The water passing through the pipes P and R, enters by the openings T the annular
chamber between the core pipe R and the enlarged part of the nozzle H, and spurts
out through the shallow grooves between the neck S and the rim of the enlarged
part of the nozzle H in a divergent direction, thereby producing a very fine and
forcible spray with a minimum of water consumed. By this arrangement also the
said grooves can be readily cleaned out as required by screwing out the core pipe R,
and refixing it after such cleaning of the grooves.
Fig. 3 (Sheet 2) is a section of the lower part of the nozzle; Fig. 4 a plan; and
Fig. 5 a plan shewing the core pipe therein.

page_text: It will be easily understood that when the air of a room is drawn into the
openings F, and after passing through the apparatus is again forced into the room,
such air is purified and cooled (or warmed if required), and that in this manner a
healthy and refreshing ventilation is produced or effected.
Instead of drawing the air from the room, external air may be supplied to the
apparatus by means of a pipe leading to the openings F, as shewn in Fig. 1, Sheet I.,
by dotted lines.
In Fig. 6 (Sheet I.) is shewn on a smaller scale the apparatus as used in a kitchen
in order to get rid of moisture or moist vapours.
Z is a sink into which the waste water escaping by the pipe in Fig. 1 is carried;
Y is a pipe through which vapours can pass into the chimney.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, I hereby declare that what I claim as of my Invention
is,—
First. The apparatus for ventilating, cooling, and warming buildings and rooms,
as represented in Sheet I. of the Drawings and described, wherein cold or hot
water admitted to the apparatus under pressure is used to purify and cool or warm
the air passed through the apparatus in the manner herein before described.
And, Secondly. The peculiar construction of the spray nozzle, represented in
Sheet II. and described, whereby a very fine and forcible spray is produced with a
minimum consumption of water, as herein before described.
In witness whereof, I, the said Heinrich Mestern, have hereunto set my hand
and seal, the Twenty seventh day of June, in the year of our Lord One
thousand eight hundred and eighty one.
