causing the rod to move up or down as the
cradle or chairis rocked. As the rod or shaft
is reciprocated the projections follow the
spiral in the socket and cause the shaft to be
5 rotated and the fan to force the air downward
upon the chair or cradle.
Having thus described my invention, what
I claim as new, and desire to secure by Let-
ters Patent, is-
10 1. The combination of the rod or shaft, the
weighted base, a clamp, adapted to be secured
to a chair or cradle, a plate through which
said shaft passes, a fan secured on said shaft,
having its blades hinged at their inner, up-
15 per corners, and means for rotating the fan
actuated by the rocking of the chair or cradle,
substantially as set forth.
2. The combination of a weighted base,hav-
ing a curved groove in its upper face, a socket
connected to said base by a knuckle-joint and 20
provided with spiral grooves in its interior,
a shaft fitted in said socket, having tangs to
engage in said grooves, a clamp adapted to
be secured to a chair or cradle, a ring-plate,
through which the shaft passes, hinged to 25
said clamp, nuts threaded on the shaft above
and below said plate, and a fan adjustably
secured to the rod or shaft, substantially as
set forth.
