An Improved Spray Producer.
DAVID SINCLAIR Author 21 Percy Road Watford Herts, do hereby declare
the nature of this invention to be as follows:-
or
A stationary or moveable arrangement by which a circular column of water,
struck from its centre outwardly by a column of air as well as laterally & at right
angles from without inwardly by another circular column of air, is formed into
spray, both air columns being simultaneously produced either by the human breath
by attached bellows. The water, or liquid compound so turned into spray is
contained either in a liquid holder or tank attached to the bellows & moveable
with it, or it (the water or liquid compound) is conveyed from an ordinary, common
or specially prepared tap by means of a tube attached to the moveable bellows
arrangement. Its use is to spray bouquets, wreathes, crosses, flowers, vineries,
greenhouses or gardens with water, liquid disinfectants or liquid vermin destroyers
& to do work hitherto done by "sprays," syringes, liquid insect-destroyers &
the like.

DAVID SINCLAIR.
An improved Spray Froducer.
1. DAVID SINCLAIR, Author, of 21 Percy Road, Watford, Herts, 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:-
A stationary or movable arrangement by which a circular column of water,
struck from its centre outwardly by a column of air as well as laterally and at
right angles from without inwardly by another circular column of air is formed
into spray both air columns being simultaneously produced either by the human
breath or by attached bellows. The water or liquid compound to be turned into
spray is contained either in a liquid holder or tank attached to the bellows and
movable with it, or it (the water or liquid compound) is conveyed from an ordinary
common or specially prepared tap by means of a tube attached to the movable
bellows arrangement. Its use is to spray" bouquets, wreaths, crosses, flowers,
vineries, greenhouses or gardens with water, liquid disinfectants or liquid vermin
destroyers and to do work hitherto done by "sprays," syringes, liquid insect-
destroyers and the like.

is the outer tube having a mouth piece at one end and a screw cap c at the
other. is a second tube inside a and secured to it. by screws e and distance
pieces el. is a shield fixed at one end of the tube d and y is a pipe connecting
the inside of d with the bottom of the vessel h containing the liquid to be sprayed.
jis the inner tube screwed at one end to the shield fand kept central at the other
end by the distance pieces k.
The action of the apparatus is as follows:-- When the mouth piece is blown
into, part of the air is deflected by the shield and passes into the vessel / causing
the fluid to rise up the pipe y into the annular space between the tubes d and jat
the end of which it meets the remainder of the air in two streams:-one through the
central tube and the other through the annular space between the tubes a and d
the latter stream being directed radially inwards by the cap c.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
1. The combination of an anunlar passage to which the liquid to be sprayed is
supplied, a second annular passage (surrounding the other) and a central passage
both connected to the same supply of air or other fluid under pressure and a cap or
deflector by which the annular stream of air is turned radially inwards.
2. Spray producers substantially as described and shown in the drawings.
Dated this 12th day of January 1895.
