Specification Accepted, 26th July, 1887.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 :-
This invention relates to what are commonly known as atomizers, or those con-
trivances employed to vaporize liquids, such as antiseptic remedies, or medicines of
any character which are applied by transforming the liquid into a vapour or fog.
The object of this invention is to improve the means employed to effect an absolute
atomization or nebulization of liquids, so that they can be inhaled and drawn into the
recesses or cavities of the lungs, or be forced into any part of the human system
where air or other gas could be introduced, or be evenly and thoroughly distributed
in the atmosphere of a sick chamber, or any apartment which it may be desired
to fumigate.
In the accompanying drawing,
Figure 1 represents a side elevation of my improved atomizer.
Figure 2 represents a vertical section through the top and cover of the receptacle
and the inlet and discharge tubes.
Figure 3 represents a vertical section of the air and liquid tubes at, and a short
distance beyond, their jet orifices.
Figure 4 represents a side elevation of a modified construction of a device embodying
my improvements.
The same letters of reference indicate the same parts in all the figures.
In carrying out this invention a receptacle of any suitable character is provided
preferably a glass bottle or jar of the form and character represented in figure 1, into
which the liquid to be atomized is poured. Said receptacle is provided with a cover, a
suitably constructed to receive therethrough and support therein the air inlet tube b,
and discharge tube c, as usual in this class of devices, except in the respects herein-
after noted.

The liquid tube d is formed as an integral part of the an
bore of the liquid tube d is straight therethrough, while the bore or hollow of the air
tube b is formed straight to a point near the jet orifice where it is turned at a right
angle thereto and to the bore of the liquid tube, as clearly represented in Figure 3 of
the drawings. By this construction the liquid and air tubes of an atomizer constitute
substantially a single straight stem, and can be readily introduced through the neck of
the smallest sized bottle. This construction also ensures at all times a proper
relationship of the jet orifices to each other.
As shown in Figure 2 of the drawing, the inlet tube is surrounded at the point
where it passes through the top or cover of the jar or bottle, with a rubber or other
similar packing e, which, while fitting closely around said tube permits it to be adjusted
vertically therein. The said tube bis eccentrically arranged in said cover or top, that
is, it passes through the cover at a point to the side of the centre thereof.
The neck of the bottle is externally screw threaded at its upper end and adapted to
be received within the internally screw threaded cap, by which construction the cap
may not only be rotated or turned on the bottle neck but he raised and lowered thereon
as well.
In the construction represented in Figure 1 a bulb f is shown as a means for
forcing air through tube b, though any other means for the same purpose might be
employed.
By the contrivance shown and described, the atomized liquid is forced against the
side of the jar and thus broken into a thin cloud or perfectly atomized or nebulized
and rendered capable, as it issues from the discharge tube as a vapour, of being inhaled
or drawn into the lungs, or introduced into any part of the human system where it is
possible for air or other gas to be forced.
When it is desired to have the atomized liquid impinge more directly against the
side of the receptacle and thus insure the breaking of the liquid into the finest possible
particles and secure perfect nebulization, the cover of the receptacle may be rotated or
turned so as to bring the jet nozzles nearer the side of the receptacle; or the same
result may be accomplished, where the sides of the vessel are angular or tapering in
form, by adjusting the tubes vertically in the cover of the receptacle, thus bringing
the jet nozzles nearer to the contracted sides of the bottle or jar."
In Figure 4 a somewhat different construction and arrangement of parts and an
illustration of the manner of adjusting such differently organized parts in different
positions, in order to nebulize liquids to a greater or less extent to meet the needs of
particular cases, is shown. In this instance the air and liquid tubes are arranged with
respect to each other as is common in atomizers, and they are located within a funnel-
shaped glass receptacle, the opening in the smaller end of which affords a discharge
orifice for the nebulized liquid. In this arrangement the atomizer is supported on an
arm g, pivotted at h to the side of the support i. Said arm is properly guided and
supported so as to maintain the atomizer in proper position, its hinged connection
with the frame providing for adjusting the atomizer so as to cause the atomized fluid
to impinge more or less direct against the sides of the receptacle.
When the atomizer is in the position represented in said last mentioned figure, the
spray will be thrown against the side of the vessel near the mouth of the funnel, but if
directed upward by rocking arm g backward on its pivot, it will come in more
immediate contact with the side of the receptacle and, as a consequence, with greater
force.
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 :-
First. An atomizer, constructed as a single and substantially straight stem, the liquid
tube being formed below or beyond the air tube, and the jet orifices being constructed
at a point between the ends of the said substantially straight stem, whereby the stem
comprising the tubes may be inserted and operated in a small vessel or phial, or vessel
or phial having a small neck, as and for the purposes set forth.

page_text: Second. In an atomizer or nebulizer, the combination of a liquid holding vessel or
receptacle and cap or stopper to which the inlet or outlet tubes are attached, with the
liquid tube and air tube constructed in a substantially straight line with the jet orifices
which are located at a point between the ends of said substantially straight stem, as
set forth.
Third. In an atomizer, the combination with the vessel or receptacle, of the liquid
and air tubes arranged with respect to the vessel to cause the atomized fluid to
impinge against the sides thereof, and means substantially as herein before described for
adjusting the jet orifices of the tubes to bring the same nearer to or remove them
farther from the side of the vessel whereby the atomized liquid may be broken into
a cloud, and the lightness or thinness of such cloud or nebulae may be varied, as
set forth.
Fourth. In an atomizer, the combination with the receptacle and its rotary cover,
of the liquid and air tubes constructed as a single and substantially straight stem, the
liquid tube being formed below or beyond the air tube, and the jet orifices being
constructed at a point between the ends of said substantially straight stem, said stem
being supported eccentrically in and by said rotary cover, and means substantially as
hereinbefore described whereby the cover may be rotated on the receptacle to bring
the atomizing point of the tubes nearer to or remove it farther from the side of the
vessel, as set forth.
