Improvements in Atomizers.
I, JOHN HENRY SCHARLING, of 737 Summer Avenue, in the City of Newark,
County of Essex, and State of New Jersey, United States of America, Electro-
plater, do hereby declare the nature of my invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
a new
The invention consists in the improved atomizer herein set forth, as
article of manufacture, and in certain novel arrangements and combinations of
parts, such as will be hereinafter fully described and finally embodied in the clauses
of the claim.
In the accompanying drawings,
Figure 1 is a side view of an atomizer embodying my invention; Figure 2 is a
vertical section of the same;
Figure 3 is an enlarged vertical section of one of the valves employed;
Figure 4 is a view of a sieve or screen employed in the valves; and
Figure 5 is a plan view of the rubber disc used in the valve.
In said views, B represents an atomizer, of any suitable form and construction,
made either of glass or metal; A is a non-compressible cap forming an air
chamber, being provided with a shoulder a and a screw-threaded portion a' by
means of which the cap can be detachably secured in the neck of the bottle B.
Said cap may be cast in halves, which are soldered or secured together to form
said chamber, or it may be made in any other well-known manner.
At or near the top of said cap is a tubular projection a², which terminates in an
ornamental enlargement a³, and is screw-threaded on the inside, as at a*.
A rubber or other flexible bulb C provided with a tube e having a flange c¹ on
the inner side of said bulb and provided with a screw-thread c² is screwed into the
tubular projection a², as will be clearly seen from Figure 2.
Of course any other well known means may be employed for securing the bulb
to said cap A, the purpose being to establish a communication between the air
chamber formed by said cap A and the compressible bulb C.
In the side of said cap A is an inlet valve. Said valve is arranged over an
opening or hole a and consists of a screw-threaded valve chamber d, which is
screwed into the tubular enlargement a in said hole a³.
Said valve chamber d is provided with a hole or vent d' and directly over said
vent is a rubber disc e and arranged behind the same is a circular piece of wire
netting or sieve f
The screw-threaded portion a' secured in the neck of the bottle B is provided
with a hole a and surrounding the same is a tubular enlargement a³, which is
screw-threaded in the inside and has screwed therein a valve chamber y provided
with a vent gl. Against the hole a' is a rubber e¹ and behind said disc is a circular
piece of wire netting or sieve f¹.
Of course it will be evident that any other well-known forms of valves may be
used in place of those shown in Figure 2, and I therefore do not limit my invention
to the exact form of valves shown.
At one side of the cap A is a bent tube a', which extends down into the chamber
formed by said cap and forms part of the same, and has on its free end a
sprayer al
Within said tube a' and terminating directly in front of an opening a" in said
sprayer is a small piece of tubing h, held in position by said sprayer, and the

page_text: opposite end of said tube extending down into the liquid in the bottle B, as clearly
shown in Figure 2.
The end of said sprayer is concave, which prevents any undue dripping of the
liquid, after the bottle has been used.
When the bulb C is compressed, the air in the cap A shuts the valve disc e
against the hole a and thereby closes the valve, while the valve disc e' is forced
away from the hole a', whereby the air in the bottle is compressed and forces the
liquid through the tube h into the sprayer and out of the opening all therein. At
the same time some of the air is forced through the tube a³ and out of the
opening a" which causes the liquid to spray, instead of passing therefrom in a
steady stream.
As soon as the bulb is released, the valve disc e¹ is forced against the hole a
which closes the valve, while the suction caused by the expanding of the bulb C,
forces the rubber disc e away from the hole a, allowing an ingress of air to again
fill the bulb.
Thus it will be seen that the back pressure in the bottle B closes the valve
connected therewith while the valve in the cap A. is opened to fill the chamber and
the bulb C.
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 claim is :-
"
1. In an atomizer, the combination, with the bottle, of a non-compressible cap
arranged on said bottle, a valve in the bottom of said cap to establish communi-
cation with said bottle, an inlet valve in said cap, an air bulb connected with said
cap, and a spray tube in said cap, being concave in the end, substantially as set
forth.
2. In an atomizer, in combination, a cap A forming an air-chamber, a screw-
threaded and tubular projection as on the side of said cap, a valve plate d secured
in said projection and a valve therein, a screw-threaded and tubular projection a
in the bottom of the cap, and a valve in said projection, a tubular projection in the
upper portion of said cap, a flexible air bulb secured to said projection, and a
tube a³ provided with a sprayer, said tube forming part of said cap, substantially as
set forth.
3. In an atomizer, in combination, a cap A forming an air-chamber, a screw-
threaded and tubular projection as in the side of the cap, a valve plate d secured
in said projection and a valve therein, a screw-threaded and tubular projection a³
in the bottom of said cap, and a valve in said projection, a tubular projection a² in
the upper portion of said cap, a flexible air bulb secured to said projection, and a
tube a provided with a sprayer, said tube forming part of said cap, a bottle B to
which said cap is secured, and a spray tube h arranged in said tube a' and
extending into said bottle, substantially as set forth.
Dated this 5th day of February 1894.
