Application 08/772,480
covering of absorbent material, wetted with a
liquid chemical. This may be embodied utilizing
conventional techniques, such as providing a
hollow body having end closures for containing a
liquid chemical thereon, the elongate body
having a plurality of openings therethrough to
allow the egress of the liquid chemical through
the openings. The exterior of the elongate body
is then provided with an absorbent material,
such as carpet-like material therearound, which
absorbs the liquid chemical emitted through the
holes. The absorbent material is therefore
wetted with the liquid chemical, such that when
foliage is contacted by the absorbent material,
the liquid chemical is applied to the foliage.
As illustrated in the drawings, the applicators
may be provided in a plurality of rows, relative
to the direction of travel [column 3, lines 3
through 18].
As for the manner in which this distributor may be
used, Robertson teaches that
[a] useful application of the invention is for
chemical application distribution to cotton
plants, where fairly rigid plants are planted on
raised peaks between troughs.
The provision of flexible connections or
spring means between the various components of
the device is particularly advantageous in such
applications applying chemicals to such rigid
foliage [column 3, lines 52 through 59].
