Improvements in and relating to the Nozzles of Apparatus for
Spraying or Distributing Paints, Liquids, and the like.
I, JAMES HARVIE MEIKLE, Junior, of 50, Kelvingrove Street, in the County of
the City of Glasgow, Manager, do hereby declare the nature of my invention
to be as follows:-
This invention has reference to improvements in and relating to apparatus for
spraying or distributing paints, liquids, and the like, and whereby the use of
sieves or strainers is dispensed with.
These nozzle apparatus for spraying paints are usually formed with a central
chamber through which pressure air passes from a lateral branch, and an annular
chamber into which the paint is admitted and drawn out, in the form of spray
by the inductive action of the air. A central spindle is passed down the air
chamber and has a conical plug or valve formed on its end, while a conical
hollow plug is screwed into chamber over this, and is preferably fitted with a
screwed on nose piece having a central hole formed through it, while an outer
conical formed plug with central outlet is screwed into paint chamber.
By my improvements a needle or wire pricker is soldered or secured to the end
of conical valve, which will pass down and clean out the orifice in surrounding
hollow plug by moving the central spindle up and down. A rubber, asbestos, or
other soft covering would be fitted round plug to make a fluid tight joint.
The central spindle would be operated by a hand lever which would open the
valve and draw back the cleaner or pricker, while the recoil action of a spring
fitted round central rod within a crosshead at its outer end would automatically
close the valve with the pricker in outlet of conical plug.

Improvements in and relating to the Nozzles of Apparatus for
Spraying or Distributing Paints, Liquids, and the like.
I, JAMES HARVIE MEIKLE, Junior, of 50, Kelvingrove Street, in the County of
the City of Glasgow, Manager, 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, that is to say:-
This invention has reference to improvements in and relating to apparatus for

page_text: spraying or distributing paints, liquids, and the like, and whereby the use of
sieves or strainers is dispensed with..
And in order that my said invention and the manner of carrying same into
practice may be properly understood I have hereunto appended an explanatory
drawing representing a sectional elevation of a nozzle apparatus as fitted with my
improvements.
Referring to said drawing:-
A
These nozzle apparatus for spraying paints are usually formed with a central
chamber A through which the paint or liquid passes from a lateral branch A¹ and
an annular chamber B through which the air is admitted from a branch B¹.
central spindle C is passed down the paint or liquid chamber A and has a spherical
or a conical plug or valve C¹ formed on its end, while a conical hollow plug A²
is screwed into chamber over this and has a central hole formed through it, while
an outer conical formed plug 132 with central outlet is screwed into chamber.
By my improvements a needle or wire pricker c is soldered or secured to the
end of valve C which will pass down and clean out the orifice in surrounding
hollow plug B by moving the central spindle C up and down. A rubber, asbestos,
or other soft covering may be fitted round plug to make a fluid tight joint. The
central spindle C would be operated by a hand lever D which would open the
valve C and draw back the cleaner or pricker while the recoil action of a
spring D¹ fitted round central rod C within a chamber D2 at its outer end would
automatically close the valve C¹ with the pricker c in outlet of conical plug B.
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:-
In spraying nozzle apparatus the fitting and use of a needle or pricker secured
to the moveable spindle for cleaning out the central orifice, substantially as set
forth.
