Opening, Closing Hand Operates Tropical
NHABITANTS of the tropical countries
where electricity is an expensive luxury
have developed the little hand-propelled
fan which Tallulah Bankhead, movie act-
ress, is seen operating in the photo on the
right.
The device consists of a four-bladed pro-
peller fastened on a handle so it can be spun
around. A piece of wire is bent, as shown,
and attached to handle. Whirling motion
of the propeller is produced when wire is
pushed back and forth along blades. This
action is obtained by flexing and contract-
ing the hand.
Electric" Fan
Thin wooden fan is kept spinning by motion of wire
lever which pushes blades when hand is opened and closed.
