Firm of J. Brandt & G. W. v. Nawrocki, Patent Solicitor and Civil Engineer,
of 124, Leipzigerstrasse, Berlin, Germany, for an Invention of "IMPROVEMENTS

PROVISIONAL SPECIFICATION left by the said Gerard Wenzeslaus von
Nawrocki at the Office of the Commissioners of Patents on the 16th August
-1881.
GERARD WENZESLAUS VON NAWROCKI, Proprietor of the Firm of J. Brandt
& G. W. v. Nawrocki, Patent Solicitor and Civil Engineer, of 124, Leipziger-
strasse, Berlin, Germany. "IMPROVEMENTS IN APPARATUS FOR PRODUCING AND
DIFFUSING SPRAY OR MIST FROM WATER OR OTHER LIQUID UNDER PRESSURE."
A communication from Heinrich Mestern, of Berlin, in the Empire of Germany.
The apparatus hereinafter described is intended to serve for producing and
diffusing spray and mist from water or other liquid under pressure for ventilating
or other purposes, so as to form as intimate contact as possible between the water
or other liquid and the air.
The apparatus is composed of the following parts :-
1. Of an end piece of the pressure pipe furnished with an external screw thread.
2. Of a valve box screwed to the aforesaid end piece of the pressure pipe, and
which, narrowing at its end, forms a conical valve seat.
3. Of a valve adapted to the abovementioned valved seat; this valve is formed
with radial guide arms or wings and with a central bored hole.
4. Of a screwed adjusting pin passing through the central hole of the before-
mentioned valve. The upper end of this pin is formed with wings which are

page_text: secured in the valve box, and the lower end projecting out beyond the end of the
valve is furnished with a screw thread.
5. Of an adjusting screw socket with internal screw thread formed thereon
closed at its lower end, which is formed into a button for turning it round. This
adjusting screw socket is screwed on to the beforementioned adjusting pin until a
shoulder of the socket touches the valve. When the adjusting screw socket is
screwed further up by means of the button at its lower end the valve is opened,
but when it is turned back the valve is closed again by the pressure of the water.
6. Of a revolving socket provided with straight or screw like notches or vanes,
which socket revolves round the adjusting screw pin and is carried by a projecting
rim or shoulder on the adjusting screw socket.
Immediately the valve is opened by turning the adjusting screw socket by
means of the button, the water under pressure shoots obliquely downwards towards
the axis of the valve, and strikes the notches or vanes of the revolving socket,
which is thus set in violent rotation by the blows of the water on such notches or
vanes, and the pressure water is broken up into very fine mist, diverging obliquely
and radially downwards.

GERARD WENZESLAUS VON NAWROCKI, Proprietor of the Firm of J. Brandt
& G. W. v. Nawrocki, Patent Solicitor and Civil Engineer, of 124, Leipziger
Strasse, Berlin, Germany. "IMPROVEMENTS IN APPARATUS FOR PRODUCING AND
DIFFUSING SPRAY OR MIST FROM WATER OR OTHER LIQUID UNDER PRESSURE.”
A communication from Heinrich Mestern, of Berlin, in the Empire of Germany.
The apparatus shown in the accompanying Sheet of Drawings, and hereinafter
described, is intended to serve for producing and diffusing spray or mist from water
or other liquid under pressure for ventilating or other purposes, so as to form as
intimate contact as possible between the water or other liquid and the air.
The apparatus is composed of the following parts:-
First. Of an end piece of the pressure pipe A furnished with an external screw
thread.
Second. Of a valve box B screwed to the aforesaid end piece of the pressure pipe,
and which, narrowing at its end, forms a conical valve seat C.
Third. Of a valve D adapted to the above mentioned valve seat. This valve is
formed with radial guide arms or wings and with a central bored hole.
Fourth. Of a screwed adjusting pin F passing through the central hole of the
beforementioned valve. The upper end of this pin is formed with wings E which
are secured in the valve box, and the lower end projecting out beyond the end of
the valve is furnished with a screw thread.
Fifth. Of an adjusting screw socket G with internal screwed thread formed thereon
closed at its lower end, which is formed into a button for turning it round. This
adjusting screw socket is screwed on to the beforementioned adjusting pin F until
a shoulder of the socket touches the valve. When the adjusting screw socket G
is screwed further up by means of the button K at its lower end, the valve is
opened, but when it is turned back the valve is closed again by the pressure of the
water.
Sixth. Of a revolving socket H provided with straight or screw like notches or
vanes, which socket revolves round the adjusting screw pin F and is carried by a
projecting rim or shoulder on the adjusting screw socket Ġ.
Immediately the valve is opened by turning the adjusting screw socket G by
means of the button K, the water under pressure shoots obliquely downwards
towards the axis of the valve, and strikes the notches or vanes of the revolving
socket, which is thus set in violent rotation by the blows of the water on
such notches or vanes, and the pressure water is broken up into very fine mist,
diverging obliquely and radially downwards.
Having now described the nature of the said Invention and the manner in
which the same is to or may be carried into effect, I would have it understood that
what I claim is,―
The pressure water rose produced by the combination of the pressure pipe A, the
fixed conical valved seat C, the axially perforated movable conical valve D, the
adjusting screw pin F, the adjusting screw socket G, and the rotating socket H,

page_text: with straight or screw like notches as hereinbefore described and illustrated in the
Drawings hereto annexed.
In witness whereof, I, the said Gerard Wenzeslaus von Nawrocki, have
hereunto set my hand and seal, this Fourteenth day of February, in the
year of our Lord One thousand eight hundred and eighty two.
Witness,
