PROVISIONAL SPECIFICATION.
An Improved Spraying Nipple and Unchokeable Stop Tap for the
Distribution of Liquid Insecticide upon Plants, and for General
Spraying Purposes.
I WILLIAM SPIERS FREEMAN of Innvicta Works Otford Kent Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the production of a simple spraying nipple or
nozzle which cannot be easily choked and the means of instantly stopping & starting
the supply of liquid thereto.
The nipple or nozzle consists of an interchangeable nipple A. (see drawing) drilled
up its centre about two thirds of the way as shewn in section the point of the drill
being ground to any suitable angle (the flatter the point the flatter will be the spray
& vice versa) the upper portion of the nipple is filed away as shewn at B & C to a
point preferably at or about the depth of the angle left by the drill point, one
way; & to about a point in line with the axis of the nipple the other way or the
portion B, C, may be filed away so as to expose the complete circle of the hole in
which case the upper portion of the nipple must be filed so that it will overhang
the hole to allow the issuing jet to impinge thereon to form the spray. Before
filing away the part B. C-a minute hole D may be bored or drilled leaving
round groove (as shewn) at D when the part B. C is cut away this has the effect of
throwing the centre of the spray higher than the remainder.

The above spray nipple is screwed into a cap E (as shewn) having attached at
its mouth a piece of fine wire gauze F to prevent the choking of the nipple by
foreign matter which can be easily removed by unscrewing this cap.
The above cap is screwed into the main portion of the arrangement, which consists
of a main casting G having a smooth hole drilled through the same as shewn at H
a short length of india rubber tube I is drawn through this hole to the upper end
(as shewn) & the passage through same is instantly closed or opened by means of
the piston J actuated by the thumb of the operator. The rubber tube can very
easily be reinstated when worn out.
The bore H can be gilded, enamelled or lined to prevent the usual chemical action
between vulcanized rubber and brass or gunmetal.

I, WILLIAM SPIERS FREEMAN of Invicta Works Otford Kent, Mechanical
Engineer, 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 has for its object the production of a simple spraying nipple or
nozzle which cannot be easily choked and the means of instantly stopping and
starting the supply of liquid thereto.

page_text: The nipple or nozzle consists of an interchangeable nipple A (see drawing left
with Provisional) drilled up its centre about two thirds of the way as shewn in
section, the point of the drill being ground to any suitable angle (the flatter the
point the flatter will be the spray & vice versa) the upper portion of the nipple is
filed away as shewn at B & C to a point preferably at or about the depth of the
angle left by the drill point one way & to about a point in line with the axis of the
nipple the other way. or the portion B. C. may be filed away so as to expose
the complete circle of the hole in which case the upper portion of the nipple must
be filed so that it will overhang the hole to allow the issuing jet to impinge thereon
to form the spray. Before filing away the part B. C. a minute hole D may be
bored or drilled leaving a half round groove (as shewn) at D when the part B. C.
is cut away this has the effect of throwing the spray higher than the remainder.
The above spray nipple is screwed into a cap E (as shewn) having attached at
its mouth a piece of fine wire gauze F to prevent the choking of the nipple by
foreign matter which can be easily removed by unscrewing the cap.
The above cap is screwed into the main portion of the arrangement which consists
of a main casting G having a smooth hole drilled through the same as shewn at H
a short length of india rubber tube I is drawn through the hole to the upper end
(as shewn) & the passage through same is instantly closed or opened by means of
the piston J actuated by the thumb of the operator. The rubber tube can very
easily be reinstated when worn out.
The bore H can be gilded enamelled or lined to prevent the usual chemical action
between vulcanized rubber and brass or gunmetal.
Having now particularly described my said invention and in what manner the
same is to be performed I declare that what I claim is
1. A spraying nipple A as shewn and described, made by cutting away about one
half of the pointed apex of the hole supplying the liquid which said pointed apex is
left by the point of the drill.
2. A screwed cap E hollowed out on the outside end in the form of a crater into
the centre of which the spraying nipple is fixed the outer rim of the crater acting
as a protector to the nipple, as shewn:
3. A screwed cap E, having a fixed or loose diaphragm of fine wire gauze placed
over the entry of same to prevent the choking of the nipple as shewn & described.
4. An instantaneous stop cock G formed by drawing a piece of rubber tubing
through a hole in same through which rubber tubing the liquid has to pass and is
stopped by the pressure of a plunger thereon actuated by the thumb of the operator,
or vice versa viz.: the tube being pressed by the action of a spring and released by
the action of pulling up the plunger.
5. Any or all of the above (separately or in combination) for use on existing or
other spraying apparatus.
