PROVISIONAL SPECIFICATION.
Improvements in Spray-producing Apparatus.
1, SAMUEL HOWARD STOTT. of The Lindens, Fulwood, Preston, in the County of
Lancaster, Agent, do hereby declare the nature of this invention to be as follows:-
My improved spray producing apparatus consists of a round metal nozzle having a
central screw-threaded hole for connecting it to the screw-threaded outlet end of the
liquid-conducting or delivery pipe and a smaller central hole through its own outlet
end. The outlet end of the nozzle is made flat in a plane at right angles to its axis
and a metal cap with a flat top is screwed down upon the outlet end of the nozzle
the said cap having a portion of its side and top cut away so as to form an opening
in the cap the opening being of such a size as to leave a part of the flat end of the
nozzle exposed but so that the central hole is covered. The water or other liquid
issuing from the central hole meets the inner or underside of the cap and forces its
way sidewise through a narrow space left between the end of the nozzle and the
underside of the cap being thereby caused to be delivered in the form of spray. The
underside of the cap may be sloped or chamfered if desired so as to increase the width
of the outlet part where the water or other liquid escapes from between the nozzle and
the cap. By the above described arrangement compound liquids as for instance water
mixed with fertilising or insect-destroying compositions may be diffused in the form
of spray with less liability of the spray producer becoming clogged or choked than
is the case with nozzles of the perforated class and in the event of any obstruction
occurring in my improved spray producer the obstructing matter may be readily
washed away by slightly unscrewing the cap and increasing the opening between its
underside and the end of the nozzle.

Improvements in Spray-producing Apparatus.
I, SAMUEL HOWARD STOTT of The Lindens, Fulwood, Preston, in the County of
Lancaster, Agent, 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:-
My improved spray producing apparatus consists of a round metal nozzle having
a central screw-threaded hole for connecting it to the screw-threaded outlet end of
the liquid-conducting or delivery pipe and a smaller central hole through its own
outlet end. The outlet end of the nozzle is made flat in a plane at right angles to
its axis and a metal cap with a flat top is screwed down upon the outlet end of the
nozzle the said cap having a portion of its side and top cut away so as to form an
opening in the cap the opening being of such a size as to leave a part of the flat end
of the nozzle exposed but so that the central hole is covered. The water or other
liquid issuing from the central hole meets the inner or underside of the cap and
forces its way sidewise through a narrow space left between the end of the nozzle
and the underside of the cap being thereby caused to be delivered in the form of
spray. The underside of the cap may be sloped or chamfered if desired so as to
gradually increase the width of the outlet part where the water or other liquid
escapes from between the nozzle and the cap. By the above described arrangement
compound liquids as for instance water mixed with fertilizing or insect-destroying or
fire extinguishing compositions may be diffused in the form of spray with less

page_text: liability of the spray producer becoming clogged or choked than is the case with
nozzles of the perforated class and in the event of any obstruction occurring in my
improved spray producer the obstructing matter may be readily washed away by
slightly unscrewing the cap and increasing the opening between its underside and the
end of the nozzle.
In the accompanying drawings.
m the event of any obstruction occurring in my
improved spray producer the obstructing matter may be readily washed away by
slightly unscrewing the cap and increasing the opening between its underside and the
end of the nozzle.
In the accompanying drawings,
Fig. 1 is a side view,
Fig. 2 another side view, and
Fig. a sectional side view of spray producing apparatus constructed as above
described.
Fig. 4 is an underneath view shewing the underside of the screw-down cap
hereinbefore mentioned.
In the arrangement shewn in Figs. 1, 2, and 3 the water issues in the form of
spray in a direction at right angles to the axis of the delivery pipe.
Fig. 5 illustrates an arrangement in which the water issues from two nozzles in
line with or in the same direction as the delivery pipe; and
Fig. 6 illustrates a single nozzle arrangement in which the water issues in the same
direction as in Fig. 5.
In the said drawings a represents the round metal nozzle having the central hole
or passage b and c the liquid-conducting or delivery pipe. d is the metal cap cut
away at the top and side at the part marked e. findicates the sloped or chamfered
part of the underside at the metal cap (answering as the outlet aperture) which I
find in actual use to answer the most satisfactorily if done in the manner shewn in
Figs. 1, 3 and 4 of the drawings. By varying the amount of outlet aperture or
space between the end of the nozzle a and the underside of the cap d the fineness of
the spray may be adjusted as required.
g is a washer interposed between the collars or flanges and for the purpose of
making a water-tight joint between the outlet or nozzle part of the apparatus.and tho
delivery pipe. The nozzle a may be conveniently unscrewed-from-the delivery pipe c
when any foreign matter or undissolved substance happens to choke up the outlet.
The obstructing matter may be readily removed by simply blowing through the
outlet in the opposite direction to that of the issuing spray. The other or inlet end.
of the delivery pipe may have a series of annular grooves (as shewn) to facilitate the
attachment thereto of a flexible hose pipe in the usual way.
The arrangement shewn at Figs: 1, 2, and 3 in which the spray issues at right
angles to the delivery pipe is particularly efficacious for enabling the spray to be
directed upon the underside of the leaves or branches of plants.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is
Spray producing apparatus in which the issuing water or liquid is caused to meet
an obstructing medium such as the under side of a cap d arranged and constructed
substantially as described and shewn in the drawings.
