A communication from abroad by EMIL HEINRICH CONRAD OEHLMANN, of Berlin, in
the Empire of Germany.
1, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street Liverpool & 6, Bank Street Manchester, both in
the County of Lancaster & 323 High Holborn in the County of Middlesex, Civil
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:-
Apparatuses, as at present in use for moistening the air, have this disadvantage
that, though they may impart the desired moisture to the apartment or building in
which they are used, yet they do not supply the fresh air for ventilating the said
building.
This disadvantage will be obviated by the use of the apparatus which forms the
object of this invention, in which fresh air under pressure is inade to enter beneath an
apparatus for sprinkling water in such manner that, not only can the amount of
saturation of the air be accurately regulated, but also the proportions in which the
fresh air is mixed with that already existing in the building.
Referring to the drawing:-
In the top of the tubular apparatus, A which is provided with openings a for
distributing the saturated air, is the sprinkling apparatus, B, containing a nozzle b in
the centre. The opening of the perforated disc through which the air enters this
apparatus, can be regulated from the outside by ineans of a lever. Underneath the
sprinkling apparatus is the compressed air nozzle D, which is supplied with com-
pressed air through a pipe c from a vontilator or fan, which latter may be feeding
several apparatuses simultaneously.
The spent water tank E is placed beneath the apparatus A.

page_text: Over the opening of the compressed air nozzle D is a fixed or adjustable conical
piece, which converts the compact stream of compressed air, as it comes out of the
nozzle, into a hollow, conical shaped-stream,-hy which the atmosphere in the building
is enveloped and caught. By the use of this conical plug, the air flowing out of the
nozzle D, is converted into the desired hollow conical stream, without any appreciable
loss of power, so that nearly the antire air pressure produced by the ventilator in the
apparatus, can be brought into use.
The apparatus works as follows:-
The throttle valve d in the air supply pipe c is opened, and the hollow cone
produced by the aforesaid conical body sucks up the surrounding air and mixes with
it before reaching the outlets a.
The pipe e which supplies water under pressure leading to the central nozzle, is also
opened so that the fountain B is set in activity. With the help of the lever s the
perforated bottom through which some of the air enters the sprinkling apparatus, is so
regulated that the stream of air converted into a conical form by the conical plug,
catches the small particles of water and distributos them through the air.
In consequence of the application of a jet of compressed air beneath the water
sprinkling apparatus, the saturated air is scattered inuch further than if it were
distributed by means of suction. The greater spread of the saturated air further
produces a more thorough mixing of the lattor with the surrounding atmosphere, so
that the air may be projected from the apparatus in a more highly saturated condition,
which makes each apparatus capable of producing more effect than would be otherwise
possible.
The apparatus for producing the compressed air may, with advantage, be connected
with a supply pipe for providing fresh pure air, or, in cold weather, warm air, to the
room or building.
This apparatus presents the following great advantage, besides that of cheapness
and simplicity, namely, that it can be applied without any alteration.
1st. As an apparatus for moistening the atmosphere.
2nd. By omitting the application of the water sprinkler, as a ventilator, and,
3rd. As a combined ventilating and moistening apparatus.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
In a ventilating or air moistening apparatus, tho combination of an arrangement
for sprinkling water, with a nozzle for compressed air placed underneath the said
water sprinkler, and a body of suitable form placed over the said nozzle so as to
convert into a hollow cone-shaped stream the air that would otherwise flow in a
compact mass from the nozzle, whereby ventilating or air moistening either separately
or simultaneously may be effected at will, substantially as described.
