PROVISIONAL SPECIFICATION.
Improvements in Spray Producers.
1, GUILLAUME ARNAUD NUSSBAUM, of 29, Ludgate Hill, E.C., Civil Engineer,
do hereby declare the nature of this invention to be as follows:
-
The object of my invention is to construct a simple and at the same time very
powerful spray producer for use with so called atomizers vapourisers or steain
sprays, or any other purpose for which spray producers may be required.
It consists of two tubes joined at an angle, preferably a right angle. The lower
part of one of these tubes, which I will call the spray tube, plunges into a vessel
containing the liquid to be projected in the shape of a fine spray. One end of the
other tube, which I will call the steam tube, is connected with a steam boiler, or
any other receptacle containing steam, compressed air or any other expansible fluid.
The opposite extremity of this steam tube is pointed and provided with a very small
hole like that of a blow-pipe. The point of this tube enters the upper part of the
spray tube to which it is hermetically fixed. The top-part of the spray tube is
closed, and a small conical hole is provided in this tube, in front of the orifice of the
steam tube. The action of this apparatus is very simple.
The steam issuing from the steam tube creates a vacuum in the spray tube, and
causes the liquid to raise in the latter until it reaches the small conical hole, at that
moment the liquid is violently blown out of the spray tube in the shape of a very
fine spray, by the steam jet issuing from the steam pipe.
In another disposition, I make use of a steam & spray tube provided both with
a pointed end & small hole. The points of these tubes are fitted at right angle in
a head piece, in such manner that the point of the spray tube covers half the orifice
of the steam tube. The head piece is provided with five holes, two at right angle,
to receive the steam and spray tubes, one large conical hole in front of the steam
tube, through which the spray is projected, and one smaller one on each side for the
admission of air.
These dispositions have for object to increase the power of the spray, by creating
a more powerful vacuum in the spray tube, and also to protect the spray points
from being blocked up and tampered with, which is a very great drawback in all
other atomizers now in use.

Improvements in Spray Producers.
I, GUILLAUME ARNAUD NUSSBAUM, of 29, Ludgate Hill E.C. 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 :-
The object of my invention is to construct a simple and at the same time very
powerful spray producer for use with so called vapourisers, atomizers or steam
sprays, or any other purpose for which spray producers may be required.
It consists of two tubes joined at an angle, preferably a right angle. The lower
part of one of these tubes, which I will call the spray tube, plunges into a vessel
containing the liquid to be projected in the shape of a fine spray. One end of the
other tube, which I will call the steam tube, is connected with a steam boiler, or
any other receptacle containing steam, compressed air, or any other expansive

with a very small hole like that of a blow pipe. The point of this tube enters the
upper part of the spray tube, to which it is hermetically fixed. The top part of
the spray tube is closed, and a small conical hole is provided in this tube, in front
of the orifice of the steam tube. The action of this apparatus is very simple.
The steam issuing from the steam tube creates a vacuum in the spray tube, &
causes the liquid to raise in the latter until it reaches the small conical hole, at that
moment the liquid is violently blown out of the spray tube, in the shape of a very
fine spray, by the steam jet issuing from the steam pipe.
In another disposition, I make use of a steam & spray tube, provided both with a
pointed end and small hole. The points of these tubes are fitted at right angles in
a head-piece, in such manner that the point of the spray tube covers half the orifice
of the steam tube. The head-piece is provided with five holes, two at right angles
to receive the steam & spray tubes, one large conical hole in front of the steam
tube, through which the spray is projected, & one smaller one on each side for the
admission of air.
These dispositions have the object to increase the power of the spray by creating
a more perfect vacuum in the spray tube, & also to protect the spray points from
being blocked up or tampered with, which is a very great drawback in all atomizers
now in use.
Fig. 1 of the accompanying drawing is a section, and Fig. 2 an elevation of a
spray producer according to my invention.
A is the kettle in which the steam is produced, B the lamp, C, a screw stopper
provided with a safety valve, D the vessel containing the liquid to be projected in
the shape of a very fine spray, a the head-piece of spray nozzle into which are fixed
the steam & spray points bb, an india rubber tube, is the front hole of the head-
piece, &e side holes for admission of air.
The apparatus acts in the following manner: Steam is generated in the kettle A,
which issues from the point & creates a vacum above spray point b', the liquid
contained in vessel D rises under the atmospheric pressure, and as soon as it reaches
the point of it is blown out in the shape of a fine spray mingled with steam.
The side holes e admit only the exact quantity of air required for the perfect
working of the apparatus.
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 :
1st.) The herein described spray nozzles for use with spray producers.
2nd.) The atomizer or spray producer as herein described & shown in the
accompanying drawings.
