NOW KNOW YE, that I, the said William Kent, do hereby declare the
said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement :-
My Invention consists in constructing a fan or punkah, or similar apparatus,
which is moved by clockwork or wheelwork, actuated by a spring or weight,
which is wound up from time to time. The fan is attached or connected to
a lever or pendulum, or spindle or crank, or other part of the clockwork or
apparatus by which it is put in motion. The fan may be plain or spiral, or of
other suitable form.
Fig. 1 of the annexed Drawings is a side elevation; and Fig. 2 is a back
elevation of a self-acting or "automatic" fan according to my Invention. The
same letters in each Drawing indicate similar parts.
a, b, c, dotted lines, indicate the base and bearings. A is a brass barrel
containing a large clock spring, which can be wound up easily & rapidly by
the long lever and handle B, d; e, f, g, are ratchet gear to check the spring.
At h are teeth on rim of the spring box, which take into the pinion i, thus
driving the wheel j, the pinion k, the wooden wheel 1, and the short crank m,
with a circular motion when the spring is wound up; n is a crank lever
longer than the one m, and which by it receives a reciprocating movement,

part of the fan.
The wooden wheel drives the small roller q, by an endless india-rubber
band, rapidly and noiselessly, and also the fly wheel r, to steady the inter-
mittent action of the fan, which last may have a silk fringe, or be made of a
bibulous material to retain "eau de Cologne," to cool and perfume the
moving air.
The bulk of the apparatus may be cased or concealed in a casing of wood.
I claim as being my Invention, 1. The long lever as applied to a self-
acting or automatic fan.
2. The noiseless wheels by which the fly wheel is driven.
8. The counterbalance and general arrangement of mechanism, including
the perfumed silk fringe as applied to such apparatus.
In witness whereof, I, the said William Kent, have hereunto set my
hand and seal, this Twenty-seventh day of January, in the year of our
Lord One thousand eight hundred and sixty.
Witness,
WM. RIDDLE.
WILLIAM KENT. (L.S.)
