"IMPROVEMENTS IN DEW SQUIRTS OR APPARATUS FOR EJECTING FLUIDS IN
FORM OF FINE SPRAY." A communication by Hugo Alisch, of Berlin, in the
German Empire.
This Invention relates to improvements in dew squirts, or apparatus for ejecting
fluid in the form of fine spray. The object of this Invention is to produce so fine
a spray of water or other fluid that the said apparatus can be applied to the most
various purposes, for instance, for providing flowers in hot houses, gardens, and
dwelling houses, or bouquets with dew-like spray; for damping curtains for
upholsterers, for damping linen before ironing, for disinfecting hospitals,
dormitories, living and other rooms or buildings, for rendering the air damp in
rooms where the same is too dry, for destroying parasites on flowers, &c., without
injuring the plants, and for various other purposes. A larger apparatus can also be
used for extinguishing burning curtains, &c.
To carry out this Invention I adopt mainly the following arrangements, viz. :-
A reservoir fitted with air pump, same having piston rod, to which a piston is
fitted, said piston rod terminating in a handle or lever for operating the air pump.
To the reservoir is attached a funnel, which is provided with a valve to which a
valve rod is attached, such rod being surrounded by a spiral spring. A water or
liquid tube in the interior of the reservoir is provided, which is partially surrounded
by an air tube. There is also a tube leading from the air pump to the air tube,
and this can be provided with a ball or other suitable valve to prevent the air from
escaping. To put the apparatus in operation, the reservoir is filled with the fluid
to be ejected in spray form by pressing down the valve in the funnel, by
depressing a button or knob attached to rod of valve, and pouring the fluid through
the funnel and valve into the reservoir. As soon as the pressure is removed from
the button or knob the valve is hermetically closed by the spiral spring. The air
pressure produced by two or three strokes of the piston in the air pump acts so on

through the air tube and around the water or fluid tube, and mixes with the fluid so
that the same is subdivided into exceedingly fine atoms. If it is required to put
the apparatus instantaneously out of operation it is only necessary to open the
valve by depressing the knob or button, when the air will escape and the apparatus
cease to act.
The advantages of this apparatus above others known up to the present time are
that a much higher air pressure can be attained than with the usual india rubber ball
system. If the nozzle is held closed and the piston operated until the same works
hard i.e., until the air in the reservoir is well compressed, the apparatus will
operate for a considerable time without further pumping. A modification of this
Invention may be used whereby the reservoir is dispensed with, and in place
thereof an ordinary bottle used. The water or fluid tube is provided with a cork
or other suitable stopper for closing the mouth of the bottle. The air pump is
attached to the bottle by straps or their equivalents. Further two air pumps can
bo employed, such pumps being connected to the air tube by two tubes. The air
pump or pumps can be placed either in the interior or exterior of the reservoir.
