Combined Sprayer and Cultivator
A spraying attachment that is operated in
connection with the gangs of a cultivator
has been devised by Frank Oldham, of
Dallas, Texas. The gangs of the cultivator
serve as supports or conductors of the spraying
liquid from the tank to the nozzles. The
machine was designed primarily for cotton
fields but does effective work on all crops
which are planted in rows and plowed with
a riding cultivator. As the plants are cultivated
and sprayed at the same time, pestiferous
insects are given a finishing treatment.
An Electric Floor-Waxer
An electric device has been perfected recently that will polish waxed
floors without the back-breaking labor of doing it by hand. The old
method took hours besides considering the unpleasantness and
drudgery of getting on one's knees and polishing in this slow manner.
This new device works without the slightest effort. It consists of a
massive bristle brush which revolves at the rate of 3000 revolutions
per minute, giving the floor a hard, glossy finish. It is also econom­
ical, for less wax is used. A switch on the handle enables one to start
and stop the motor instantly. This machine fastens to any electric
light socket and is ready to use at a moment's notice.
