Improvements in Atomizers or Spray Producers.
I, HARLEY MITCHELL DUNLAP of 58 Grant Street Battle Creek Michigan
United States of America Doctor of Medicine do hereby declare the nature of this
invention to be as follows:-
This invention relates to the manner in which I construct and arrange atomizers
or appliances for producing spray from liquids in order that such spray may be
inhaled or directed to any desired part, in a simple and convenient manner by the
patient himself or by the attendant as may be desired.
In carrying my
invention into effect I construct a vessel preferably of glass which
I make my receiver and spray chamber; upon the upper portion or neck of this
bottle or vessel I make a cap connection by providing a threaded surface or screw
upon the neck to receive a like screw formed upon the closing cap, and I make a
perfectly air tight joint between the cap and the neck by means of a rubber cork
or leather washer, or by means of a ring of any suitable packing material.
I prefer to make my cap in the form of a hard rubber or like material plug having
holes and ports provided therein for enabling an air tube to be connected externally,
an inbaling or exit tube or branch externally, also an inlet tube externally; while
internally I provide for an inlet and exit port or opening each independently
formed, and also an opening for permitting my spray producing tube to be readily
attached. Upon the outer surface of my plug or cap I prefer to mount a metal or
other suitable material screwed ring or union cap for attaching the plug and its
connections to the neck of the bottle or vessel. Sometimes I form the thread or
screw upon the plug cap direct and dispense with the independent ring for screwing
the one to the other.
My spraying tube I make of hard rubber or like material and in two parts joined
together by a nipple or union piece. The upper part of the tube I make with a
thread or screw to attach to the plug, and the lower part of this tube with a screwed
surface to receive the nipple or union piece. The bottom joint piece of the spraying
tube I make with its end open which enters the liquid within the vessel and with
its upper end screwed to receive the nipple or union piece; within this lower portion
of the tube I make a hole or outlet passage which I form to come opposite to the
side exit hole within the nipple piece, so that when the whole is connected together
as one piece or as one tube the air passing down this tube sucks up or draws up the
liquid from within the lower end of the tube and ejects it against the side of the
vessel thus producing a spray within the upper portion of the vessel. The spray thus
formed within the bottle or vessel I take off by means of a tube attached to my
exit branch on the cap of the vessel, and I provide either a mask upon the end of
the tube for permitting inhalations by the patient, or I attach a nasal tube on a
bulb ended tube to suit the particular requirements of the treatment desired.
I connect an air bulb to the spray producing junction piece, so that when this
bulb is compressed and released by hand pressure a spray may be induced within
the bottle or vessel. I employ any well known suction valve within the air bulb.
The inlet nipple I may close with a stopper at will when it is desired to direct
the vapour or spray through the nasal or other tube instead of for inhalation
purposes; and I sometimes make a connection to an oxygen or other supply when it
is required to provide such gas instead of ordinary atmospheric air to force up the
spray from the vessel.

page_text: I vary the shape and form of my bottle and its connections to suit any particular
requirement; and I introduce special preparations and solutions within the vessel
to enable various diseases and affections to be treated with their particular
remedies, the form of my spraying tube and its connections permits of balsamic
sprays being produced without fear of the instrument being clogged or becoming
stopped up.
Instead of a simple hand air charging vessel an ordinary air pump may be
applied to work with my atomizer.

Improvements in Atomizers or Spray Producers.
1, HARLEY MITCHELL DUNLAP, of 58 Grant Street, Battle Creek, Michigan,
United States of America, Doctor of Medicine, 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 the manner in which I construct and arrange atomizers
or appliances for producing spray from liquids in order that such spray may be
inhaled or directed to any desired part, in a simple and convenient manner, by the
patient himself or the attendant as may be desired.
In the accompanying sheet of explanatory drawings―
Figure 1 is a front elevation of my atomizer.
Figure 2 is a detail elevation, of my cap or head for receiving the tubes, and
Figure 3 is a plan of the same.
Figures 4, 5, 6 and 7 are detail elevations of my spray producing tube.
Figure 8 is an elevation of a bulb ended nozzle for attachment to my spray
outlet tube.
In carrying my invention into effect I construct a vessel preferably of glass which
I make my receiver and spray chamber A; upon the upper portion or neck of this
bottle or vessel I make a cap connection by providing a threaded surface or screw
upon the neck to receive a like screw formed upon the closing cap B, and 1 make a
preferably air-tight joint between the cap and the neck by means of a rubber
cork or leather washer C, or by means of a ring of any suitable packing material.
I prefer to make my cap in the form of a hard rubber or like material plug B,
having holes and ports provided therein for enabling an air tube D to be connected
externally, an inhaling or exit tube or branch externally, also an inlet tube
externally; while internally I provide for an inlet d and exit port e or opening,
each independently formed, and also an opening for permitting my spray producing
tube G to be readily attached. Upon the outer surface of my plug or cap
I prefer to mount a metal or other suitable material screwed ring or union cap B' for
attaching the plug and its connections to the neck of the bottle or vessel.
Sometimes I form the thread or screw upon the plug cap B direct, and dispense
with the independent ring B' for screwing the one to the other.
My spraying tube GI make of hard rubber or like material and in two parts G G¹
joined together by a nipple or union piece H. The upper part G of the tube
I make with a thread or screw g to attach to the plug B, and the lower part of this
tube with a screwed surface to receive the nipple or union piece H. The bottom
joint piece G' of the spraying tube I make with its end open which enters the
liquid within the vessel, and with its upper end screwed to receive the nipple or
union piece; within this lower portion of the tube 1 make a hole or outlet passage K
which I form to come opposite to the side exit hole H' within the nipple piece H,

page_text: so that when the whole is connected together as one piece or as one tube, the air
passing down this tube sucks up or draws up the liquid from within the lower end of
the tube and ejects it against the side of the vessel thus producing a spray within
the upper portion of the vessel. The spray thus formed within the bottle or vessel
I take off by means of a tube E attached to my exit branch on the cap of the
vessel, and I provide either a mask L upon the end of the tube for permitting
inhalations by the patient, or I attach a nasal tube or a bulb ended tube M to suit
the particular requirements of the treatment desired.
I connect an air bulb N to the spray producing junction piece, so that when
this bulb is compressed and released by hand pressure, a spray may be induced
within the bottle or vessel. I employ any well known suction valve n within
the air bulb.
The inlet nipple D I may close with a stopper at will when it is desired to direct
the vapour or spray through the nasal or other tube, instead of for inhalation
purposes; and I sometimes make a connection to an oxygen or other supply when
it is required to provide such gas instead of ordinary atmospheric air to force up
the spray from the vessel.
I vary the shape and form of my bottle A and its connections to suit any
particular requirement; and I introduce special preparations and solutions within
the vessel to enable various diseases and affections to be treated with their
particular remedies, the form of my spraying tube and its connections permits of
balsamic sprays being produced without fear of the instrument being clogged or
becoming stopped up.
Instead of a simple hand air charging vessel an ordinary air pump may be
applied to work with my atomizer.
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 arrangement of a spray producing tube formed in two
parts, having a side opening in the lower members and having a hollow coupling
for uniting the two parts together, such coupling being formed with an outlet to
register with the side opening in the lower member of the tube, substantially
as and for the purposes hereinbefore described and as illustrated in the
accompanying drawings.
2. In an atomizer, the combination with a vessel or reservoir of a head secured
to the top thereof, the head having ports opening from the bottom through its
sides and adapted to connect with an air supply bulb, to an independent air or other
gas supply, and also to an inhaler mask or spraying outlet tube, and having
a spray producing tube attached to the inside of the head, substantially as and
for the purposes hereinbefore described and as illustrated in the accompanying
drawings.
