PROVISIONAL SPECIFICATION.
Improvements in Appliances for Spraying Medicated or other
Liquids or Solutions.
I, THOMAS WOODRUFF, of Lapwing Lane, Withington, near Manchester, in
the County of Lancaster, Pharmaceutical Chemist, do hereby declare the nature
of this invention to be as follows:-
This invention is primarily designed for applying to the throat or nose in the
form of a spray a medicated liquid or solution but may be employed for spraying
perfumes or other liquids.
It consists essentially of two tubes one placed inside the other and both provided
with fine nozzles the nozzle of the inner one projecting into the outer one to within
a short distance of the end the outer tube being provided with a reservoir for the
liquid or a connecting tube for inserting in the liquid and the inner one connected
by a tube or otherwise with a ball or other appliance for forcing a current of air
through.
In carrying out the invention I provide two tubes of different diameters so that
one will fit inside the other. At one end both these tubes are drawn out to a fine
Bozzle or nozzle with a fine aperture therein that of the inner tube being capable
of being inserted in that of the outer tube. At the other ends the two tubes are.
connected together by a cap or cover which seals the end of the outer one and
provides means for adjusting the position of the inner one leaving the end open.
To the outer tube preferably near the closed end is fitted a reservoir to hold the
liquid or it is fitted with a connecting tube to be inserted in the liquid. This
reservoir is preferably graduated or marked with a scale.
To the open end of the inner tube is attached a pipe leading to a bulb or other
appliance for forcing air through the tubes.
The appliance may be made to deliver the spray either horizontally or vertically
or at any desired inclination thereto and the nozzles may be either straight curved
or inclined as found desirable for directing the spray as required.
The tubes and other parts may be made of glass, vulcanite, transparent celluloid,
or other suitable material.

Improvements in Appliances for Spraying Medicated or other
Liquids or Solutions.
I, THOMAS WOODRUFF, of Lapwing Lane, Withington, near Manchester, in
the County of Lancaster, Pharmaceutical Chemist, 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 is primarily designed for applying to the throat or nose in the
form of a spray a medicated liquid or solution but may be employed for spraying
perfumes or other liquids.

page_text: It consists essentially of two tubes one placed inside the other and both provided
with fine nozzles the nozzle of the inner one projecting into the outer one to
within a short distance of the end the outer tube being provided with a reservoir
for the liquid or a connecting tube for inserting in the liquid and the inner one
connected by a tube or otherwise with a ball or other appliance for forcing a
current of air through.
It will be fully described with reference to the accompanying drawings.

Fig. 3. Transverse section on line a-y Fig. 2.
Fig. 4. Longitudinal section without the reservoir D.
Fig. 5. Longitudinal section of curved form for spraying the larynx.
Fig. 6. Longitudinal section nasal spray.
I provide two tubes A and B of different diameter the tube B being fitted inside
the ether. The tubes are preferably cylindrical as shown and are placed
concentrically. Both the tubes are drawn out to fine nozzles a b at the delivery
end the nozzle & fitting into the nozzle a leaving a fine annular aperture around
the inner nozzle which is provided with a fine central aperture.
At the opposite ends the two tubes A and B are attached or connected together
by a cover or collar C which seals the end of the outer tube A and provides means
for adjusting the position of the inner one B by means cf the screw c thereou
leaving the end bi open. A checknut clocks the two tubes in position when
adjusted.
Instead of the screw the cover or collar C may be formed of cork rubber or
other material and form a slide for the inner tube to pass through or the two tubes
may be permanently attached.
To the outer tube A preferably near the closed end is fitted a reservoir D to
hold the solution or medicament. The reservoir D is connected to the tube A by
a small tube d which passes from the bottom of the reservoir to the under side of
the tube A. Or as in Fig. 6 when the nasal spray is intended to be used in a
vertical position by a small aperture or passage d' leading from the bottom of the
reservoir to the interior of the tube A. The reservoir D is preferably graduated
or marked with a scale to indicate measured quantities.
Instead of the reservoir D the tube d may be open at its free end to which may
be attached a rubber tube E for insertion in a bottle or other vessel containing the
solution.
The free end of the inner tube B is open and to it is attached by a pipe or
tube F an elastic bulb or bellows G or other appliance for foreing air through
the tubes.
Fig. 5 shows a modified form of appliance curved longitudinally to reach the
larynx.
The appliance may be made to deliver the spray either horizontally or vertically
or at any desired inclination thereto and the nozzles may be either straight curved
or inclined as found desirable for directing the spray as required.
The tubes and other parts may be made of glass vulcanite, transparent celluloid,
or other suitable material.
When in operation the solution or medicament is placed in the reservoir or
receiver D and air is forced through the inner tube B by means of the bulb or
bellows G. The current of air issuing through the nozzle 6 induces a current
in the aperture surrounding it in the nozzle a exhausts the air in the tube A and
draws up the solution through the tube d discharging it in the form of a fine
spray.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.-
1. An appliance for spraying medicated or other solutions constructed with two

page_text: tubes fitting inside the other both drawn to a fine nozzle at one end the nozzle of
the inner one projecting into that of the outer one the other end of one tube being
closed and connected to a reservoir for the solution and of the other tube being
connected with a bulb or bellows for forcing a current of air through to exhaust
the air and produce a spray substantially as described.
2. An appliance for spraying medicated or other solutious constructed of two
concentric tubes curved longitudinally to reach the larynx provided at one end
with spraying nozzles and at the other with a receiver for the solution and an air
bulb or bellows for forcing air substantially as described.
3. In an appliance for spraying medicated or other solutions the combination of
the inner and outer concentric tubes A and B the nozzles a and b one projecting
into the other, the receiver D and tube d for supplying the solution and the tube E
and bellows or bulb G for forcing air through to create a spray substantially as
described and shown.
4. An appliance for spraying medicated or other solutions having the several
parts constructed and arranged in combination substantially as described.
