Again referring to the drawing, the ‘atomizer
30
‘is composed of a soft rubber bulb 2, which is
provided with an open neck 28, the neck being
hollow and opening into an enlarged cavity of
the bulb and which bulb is closed except as to
the opening 2ID in the neck. The bulb has a ?at
surface on the bottom on which to rest.

The atomizer head I, is made of screw stock

The
bulb 2 is constructed to receive a ?uid receptacle
5, as illustrated in Fig. 1 and tapers upwards
and downwards from its middle to form the neck
40 2EL at its upper end with opening 2b and an an,
nular air channel 8, in the form of a recess on
sages into the mixing chamber l5 of nozzle 4.
As will be noted the atomizer head has mount
ed on it nozzle 4 onto the outer end of which is
screwed cap 3 to seal the end of the nozzle with
a gasket seated on the inside of cap 3 (not 25
The atomizer head also has mounted

at'the neck end I‘1 a ?uid tube 29 provided with
notches 30 for attaching rubber hose 6 to reach
the» bottom of the ?uid receptacle and in the
?uid passage 21, a plug 28 is arranged to close 30
that passage, so thatthe ?uid will be elevated
through rubber tube 6 into passage 3|, thence
into passages 21 and 26 into opening l5a in the
mixing chamber l5 and ejected through‘opening

provided in the air passage [6, at its upper and
lower enlarged openings, with two check valves
