Improvements in Spray-producers.
I, CARL RUPPOLT, of 65 Wasserthor Strasse, Berlin, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a spray-producer which differs from the apparatus
heretofore used in not being blown with the mouth, two of its sides being pressed
together to cause an effective spraying of the liquid. With this improved
apparatus I may also produce either a full jet or discharge the liquid in drops.
I will proceed to describe two forms or arrangements, one of which is chiefly
designed as a pocket spray-producer, while the other is made of larger size.
The former arrangement comprises a round double cap which is formed of two
halves soldered together. These caps are made of corrugated sheet metal so that
they can be easily moved towards each other by exerting a little pressure at the
centre by the thumb and a finger. A spring forces the caps asunder again on the
pressure of the thumb and finger being relaxed.
The caps contain the liquid to be atomized, which is spurted out through a fine
tube and an aperture owing to the fact that on the caps being pressed together the
air above the liquid will be compressed, thereby compelling the latter to rise in
the said tube and leave through the aperture. But simultaneously with the liquid
a portion of the compressed air leaves through this aperture and impinges against
the liquid in an oblique direction, thereby producing a very fine spray.
The caps
are provided with an interiorly screw-threaded socket adapted to receive a screw
plug with an inner cavity to the periphery of which the before-mentioned tube is
soldered and which terminates in a taper depression or bore. Almost immediately
in front of the aforesaid aperture is the end of the tube which is pointed a little in
order that a sufficient space may be left between its orifice and the said aperture
for the simultaneous outlet of the compressed air.
In case the spray producer is to be carried in the pocket it is needful to obviate
the accidental outlet of the liquid. For this purpose I provide above the said
aperture a disc adapted to be turned about a pin or a screw and provided with a
slot for a second screw. By taking hold of a nose on the disc the latter may be
displaced so that either a hole at the centre of the disc will be just above the
aforesaid aperture and allow the liquid to pass out freely, or that the said disc will
be on one side and cover the aperture, thus precluding the liquid from passing out.
The screw plug may be easily removed from the socket secured to the caps, in
order to enable these caps to be supplied with fresh liquid.
If this spray producer is turned so that the said aperture is directed sideways
the liquid will pass into the interior cavity of the screw plug, and if the caps are
then pressed together no air can pass out with the liquid, which is forced out alone
in the form of a thin jet.
Moreover by holding the spray producer lightly in the hand and swinging it
with a jerk the liquid will be ejected in the form of drops from the aperture, the
apparatus may therefore also be used for letting drops fall on handkerchiefs,
garments or the like.
Instead of having a round form the cap may also be made of hexagonal,
octagonal or other suitable form, the only condition to be fulfilled for operating the
apparatus being that the caps shall permit of being momentarily pressed together
aud shall then expand again.
In the second arrangement the tube soldered to the screw plug is bent to an

page_text: angle and terminates in a mouth-piece provided with an opening, which tube also
leaves in the said mouth-piece a small intermediate space for the simultaneous
outlet of the air compressed by the caps. The said mouth-piece is inserted into a
separate cap which forms a collecting chamber for the compressed air. Upon this
cap is mounted an air inlet valve which consists of a sheet of mica with a sieve of
wire gauze underneath; both are covered by a small disc which has an aperture at
the centre. In order to protect this valve from injury or keep off the dust I
provide it with a small cap having lateral holes. This valve serves for rapidly
replacing the air which is used each time the caps are pressed together. Whilst
in the pocket spray-producer the fresh air enters through the same aperture
through which the compressed air has passed out, I provide in the larger spray-

spray-producers the aforesaid opening is too small for letting the air through with
sufficient rapidity when the caps rapidly expand again after they have been pressed
together. Accordingly this separate air inlet will be required if the caps exceed a
certain size, that is to say if the apparatus is to be made, not as a pocket spray-
producer, but for use on a table or for similar purposes. It is then expedient to
provide the caps with legs or a stand by which it can be supported upon the table.

the same is to be performed, to be particularly desire
the following statement :-
My invention relates to a spray-producer which differs from the apparatus
heretofore used in that it is not intended to be blown with the mouth two of its
sides being pressed together to cause an effective spraying of the liquid. With
this improved apparatus I may also produce either a full jet or discharge the liquid
in drops.
In the accompanying drawing
Figure 1 is a side elevation partly in section of one form of my improved
apparatus.
Figure 2 is a plan or edge view thereof.
Figure 3 is a transverse section and
Figure 4 is a vertical section of the upper part of a modified form of apparatus.
Similar letters of reference indicate corresponding parts in the several figures
of the drawing.
The apparatus shown in Figures 1 to 3 is chiefly designed as a pocket spray-
producer, while that shown in Figure 4 is made of a larger size.
The former arrangement comprises a vessel or body a which is formed in two
halves soldered together. These two parts are made of corrugated sheet metal
so that they can be easily pressed together by exerting a little pressure at the
centre by means of the thumb and finger. A spring forces the two halves of
the vessel asunder again on the pressure of the thumb and finger being relaxed.
The said vessel contains the liquid to be atomized, which is ejected through a
fine tube and an aperture e owing to the fact that on the two parts of the vessel
being pressed together the air above the liquid will be compressed, thereby
compelling the latter to rise in the said tube and leave through the aperture e.
But simultaneously with the liquid a portion of the compressed air leaves through
this aperture e and impinges against the liquid in an oblique direction, thereby

page_text: producing a very fine spray. The vessel a is provided with an interiorly screw-
threaded socket c adapted to receive a screw plug d with an inner cavity to the
periphery of which the before-mentioned tube is soldered, and which terminates
in a taper depression or bore. Almost immediately in front of the aforesaid
aperture e is the end of the tube f which is pointed a little in order that a sufficient
space may be left between its orifice and the said aperture for the simultaneous
outlet of the compressed air.
In case the spray-producer is to be carried in the pocket it is necessary to
obviate the accidental outlet of the liquid. For this purpose I provide above the
said aperture e as shown in Figure a disc g adapted to be turned about a pin or a
screws and provided with a sloth for a second screw s¹. By taking hold of a nose
or projection g' on the disc g the latter may be displaced so that either the hole i
at the centre of the disc will be just above the aforesaid aperture e and allow the
liquid to pass out freely as shown in Figure 1 or that the said disc will be on one
side and cover the aperture e thus preventing the liquid from passing out, as shown
in Figure 2.
The screw plug d may be easily removed from the socket secured to the
vessel a in order to enable the latter to be supplied with fresh liquid.
If this spray producer is turned so that the said aperture e is directed sideways
the liquid will pass into the interior cavity of the screw plug d and if the two parts
of the vessel a are then pressed together no air can pass out with the liquid which
is forced out alone in the form of a thin jet.
Moreover by holding the spray producer lightly in the hand and swinging it
with a jerk the liquid will be ejected in the form of drops from the aperture e,
the apparatus may therefore also be used for letting drops fall on handkerchiefs,
garments or the like.
Instead of having a round form the cap may also be made of hexagonal,
octagonal or other suitable form, the only condition to be fulfilled for operating the
apparatus being that the two parts shall permit of being momentarily pressed
together and shall then expand again.

The said
In the arrangement shown in Figure 4 the tube f soldered to the screw plug di
is bent to an angle and terminates within a nipple k provided with an opening e',
which tube also leaves in the said nipple a small intermediate space for the simul-
taneous outlet of the air compressed by the two parts of the vessel a.
nipple k is inserted into a cap which forms a collecting chamber for the compressed
Upon this cap is mounted an air inlet valve m which consists of a sheet 7 of
mica with a sieve p of wire gauze underneath, both are covered by a small disc r
which has an aperture at the centre. In order to protect this valve from injury or
keep off the dust I provide it with a small cap n having lateral holes o. This valve
serves for rapidly replacing the air which is used each time the two parts of the
vessel a are pressed together. Whilst in the pocket spray-producer Figures 1 to 3
the fresh air enters through the same aperture e through which the compressed air
has passed out, I provide in the larger spray-producer Figure 4 a separate air
inlet at oo with the before-described valve. For large spray-producers the
aforesaid opening e' is too small, for letting the air through with sufficient rapidity
when the sides of the vessel rapidly expand again after they have been pressed
together. Accordingly this separate air inlet will be required if the said sides
exceed a certain size, that is to say the apparatus is to be made, not as a pocket
spray-producer, but for use on a table or for similar purposes. It is then expedient
to provide the vessel a with legs or a stand by which it can be supported upon the
table.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claun is :-
First. A spray producer, in which the vessel for the liquid consists of two
corrugated halves a which on being pressed together compress the air enclosed

page_text: therein, which air forces out the liquid through the tube fand the aperture e, and
at the same time passes also through this aperture e thus spraying the liquid.
Second. In the spray producer characterized in the first claim a cover g for the
aperture e for preventing the outlet of the liquid.
Third. In the spray producer characterized in the first claim a nipple k provided
in a cap and a valve p q r for the separate inlet of air.
