Improvements in or relating to Waterspraying Apparatus for Green-
house and Horticultural Purposes generally.
I, THOMAS OAKMAN, of Scotland Green Farm, Ponders End, Middlesex, Florist,
do hereby declare the nature of this invention to be as follows:
The object of this invention is to construct an apparatus by which a spraying
of fine jets of water in any direction can be mechanically effected in a greenhouse
or for horticultural purposes generally.
The invention is more particularly intended for houses under great heat for
growing cucumbers or other fruit or plants and in which fine jets of water of dew
like formation is essential both above and below the leaves and fruit while growing
to protect it or them from parasites, and also as a means for rapidly bringing the
fruit or plants to perfection.
To carry my invention into practice, I suspend from the sash bars or astragals,
or I support from the staging, or some other portion near the eaves, a horizontal
water pipe, which by necessary union or other joints may have a rotative action
imparted to it, said pipe having short branches with spraying nozzle ends to enable
the water used to be directed to any part of the structure within the circle of the
pipe's rotation and within range of the spray jets, a hand wheel being fitted on the
end of the pipe to enable it to be turned.
The pipe and branches may have an all round travel and when the branches
are set uppermost the pressure of water can be exerted against the glass roofing
for breaking the spray up into finer particles of dew or mist like form which
pervades the house assisted by the heat imparted thereto, if heat be employed.
Several of such pipes may be arranged end to end, or in proximity in a very
long house, so that they appear in sections, each for separate operations.
In addition to the foregoing, I purpose fitting one or more pipes under the
ridge, said pipes being provided with nozzle branches having fine spray jets
which may be turned by hand to direct the spray of water in the desired direction
downwardly or against the glass for more finely dividing it. This will be found
of service with plants requiring the tops of the leaves being kept moist only, and
may or may not be used in conjunction with the eaves pipes before mentioned.

I, THOMAS OAKMAN, of Scotland Green Farm, Ponders End, Middlesex, Florist,
do hereby declare the nature of this invention and in what manner the same is to

page_text: be performed to be particularly described and ascertained in and by the following
statement:
The object of this invention is to construct an apparatus by which a spraying
of fine jets of water in any direction can be mechanically effected in a greenhouse
or for horticultural purposes generally.
The invention is more particularly intended for houses under great heat for
growing cucumbers or other fruit or plants, and in which fine jets of water of dew
like formation is essential both above and below the leaves and fruit while growing
to protect it or them from parasites, and also as a means for rapidly bringing the
fruit or plants to perfection.
To carry my invention into practice, I suspend from the sash bars or astragals,
or I support from the staging, or some other portion near the eaves, a horizontal
water pipe or pipes which by necessary union or other joints have a rotative action
imparted to it or them, said pipe or pipes having short branches with spraying
nozzle or perforated at intervals to enable the water used to be directed to any part
of the structure within the circle of the pipe's rotation and within range of the
spray jets, a hand wheel or lever being fitted on the pipe to enable it to be turned
from any part of the house as shall be found most suitable.
The pipe and branches may have an all round travel and when the branches
are set uppermost the pressure of water can be exerted against the glass roofing
for breaking the spray up into finer particles of dew or mist like form which
pervades the house assisted by the heat imparted thereto, if heat be employed.
Several of such pipes may be arranged end to end, or in proximity in a very
long house, so that they appear in sections, each for separate operations.
In addition to the foregoing, I purpose fitting one or more pipes under the
ridge, said pipes being provided if desired with nozzle branches having fine spray jets
which may be turned by hand to direct the spray of water in the desired direction
downwardly or against the glass for more finely dividing it. This will be found
of service with plants requiring the tops of the leaves to be kept moist only, and
may or may not be used in conjunction with the eaves pipes before mentioned.
My invention will be more clearly understood by reference to the annexed
diagram in which A is the water pipe near the eaves B and is suspended or hung
in metal loops C, or otherwise as desired. D, D, short branches with nozzles on
the pipe A E hand wheel on the pipe A to enable it to be turned in the required
position.
For convenience I have shown a pipe near each eave of the forcing house, and
the hand wheels are coupled by a chain F so that the sprays of water from the
nozzles D, D, may if the nozzle be suitably arranged, cross the path of each other,
a portion of each jet striking the other to break up the spray still finer than that
issuing from the nozzles, but if the nozzles of each pipe A be turned upward, the
pressure of the water against the glass will smash the water into very fine mist
or of dew like formation. This position of the nozzles is the best when the pipe A
is first charged, because all the branches and nozzles D are equally filled before
the water issues and that ensures an equal treatment of all the plants for the full
length of the house or for the lengths of separate pipes according to the manner
in which they are fitted notwithstanding the altered position of the nozzles by
turning the pipe A round.
This suspending or supporting of rotatable water supply pipes in a greenhouse
or horticultural buildings for water spraying purposes is proved to be of importance
for many kinds of plants and fruit, particularly for cucumbers and the like for
which a continuously fresh moist heat is essential.
Alone or in conjunction with the eaves pipes A, I may use a perforated pipe G
under the ridge H and said pipe G may have nozzle branches I as represented and
this pipe G may be rotatable or fixed but preferably movable so that the branches
and nozzles I can if suspended by loop irons J or otherwise be turned for the sprays
of water to fall like rain upon the plants, or be arranged that the sprays of water

page_text: smash against the glass and be broken up into fine particles, or if desired baffles
or check plates can be affixed to the nozzles for breaking the water up into fine
spray like globules, or of mist, or dew.
Although I have referred to my rotatable spray pipes being near the eaves, I do
not limit myself as to the position of the pipes shown on the drawing since with
such houses having very low stagings and low eaves said perforated and turnable
pipes can be set in the path just above the floor and instead of having an alround
rotation, they can be rotated or oscillated to a given angle only for the jets or spray
of water to wash upwardly from opposite sides. This will be invaluable for plants
subject to green fly, aphis or red spider, the up-dash of water effectually clearing
them off and washing the leaves of the plants to preserve cleanliness.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:-
1. In horticultural buildings, the employment of rotatable water supply pipes
perforated with holes or provided with branch nozzles for directing water spray
therefrom in the desired direction, say, on to plants, or up under the leaves thereof,
or against the glass or against baffles for breaking up the sprays, as and for the
purposes hereinbefore set forth and substantially as shown by the annexed drawing.
2. Fitting perforated water supply pipes in horticultural structures in such
manner that water under pressure can be directed as spray by turning such pipes
as desired from outside or from inside the structure substantially as set forth.
