We can, it is
true, obtain a little air by moving a fan, but, aside from the fact that
this exercise soon becomes tiresome, it prevents the use of the hand that
is fanning.
[Illustration: FIG 2.--AN APARTMENT FAN.]
The new apparatus which have just been devised by Mr. G. Bozerian permit
of one's fanning himself all day long if he wants to, without any
fatigue, and while he is eating, reading, writing, etc.
In one of these apparatus, designed to be used in the open air (Fig. 1),
we find a table, a tent, and a fan combined; but as each part is
independent, we can have the table and fan without tent, or the fan and
pedals alone without table or tent. Under the tent there is arranged a
frame which pivots freely in apertures formed in the uprights that
support both the tent and table. This frame is connected, through two
levers, with the pedals upon which one's feet rest. The motion of the
pedals is an alternating one like those of sewing machines; but while in
the case of the latter a pressure has to be exerted that soon becomes
very tiresome, the motion in Mr. Bozerian's apparatus is so easy that it
is only necessary to raise the toes of each foot in succession in order
to produce a swing of the fan through the weight alone of the foot that
is pressing. The frame, which when at rest hangs perpendicularly,
describes about a quarter of a circle when the extremity of the foot is
raised about an inch.
