was claimed could not be overcome,
was the variability of the wind ard the
consequent cratic fluctuations of the
electric pressures which rendered their
utilization impossible by subjecting
the ordinary mechanical connections to
excessive ard fatal strains.
Early II his experiments, Mr.. Feeiy
found that one Of the first problems to
be solved was TO determine accurate
~ the WIND veiCcities and efficiencies
during the various months Of the year.
This was determined by the use of
an annemOmeter, made especially for
that particular purpose and very SINH
lar to those in use by the United States
weather buTeG u, with 4 he exception that
While the government instruments
record the mile rate of the wind, the
one made for Mr.. F5e'y recorded the
wird at each fiftieth Of mile.
After some months of hard thinking
and harder work, the machinery with
all its Improvements was finally set in
place. and when all connections were
made Mr.. Feely anxiously awaited the
first trial which should demonstrate the
failure or success OF his pains and
labor.
The windmill proper is the ordinary
kind, common in all out of town and
country places where there is no public
water supply The steel frame or sup
rcrts ext nd fifty fest above the sccond
story Of the stables as shown in the
picture.
At the top of this frame are the wheel
and fan which are operated by the
wind. As the wheel revolves under the
influence Of the slightest breeze it oper-
ates q series of cog wheels, which work
UPON =. lOrg vertical shaft running from
TIE head of the machine to the base
rent or cellar of the stable where it
communicates with a second shaft lead
Jig directly to the dynamo Of the plant.
TWO SETS OF WIRES.
From this dynamo lead two sets of
wires. One set carry the current to
the various parts of the estate where
it is utilized for power purposes and for
lighting, while the other set of wires
receive the surplus current and store it
in storage batteries for use when the
tickle wind is not sufficiently strong to
give power enough to supply the neces-
s6ry voltage.
When there is high wind there is
naturally much stronger current than
Is necessary, and in order that it may
rot be wasted, or play havoc with the
lights the surplus energy is led into
these storage batteries and there kept
until needed.
\ feature of this dynamo is that the
same ore which generates the current
when there is a breeze, also acts as a
with the energy always on hand in the
storage batteries. This double service
by dynamo has never before been &C
complished.
In the comparatively light breeze
which was blowing when the first trial
was made, the wheel of the windmill
began to slowly revolve. then faster
and faster it went until it looked like
one solid piece of circular wood spin
ming about in the air.
number of electrical lights had been
put up in the stable as a test, and
when these were turned on after the
windmill had been working some time,
they showed a brilliantly steady light,
the eGuol of that supplied by any cleo
tric light company in the country.
The experiment was q success and 6
combination CT windmill and motor had
been found at such a comparatively
Slight cost that the matter of expense
was hardly worth considering.
Once the practicability of the ma
chineTy was assured, Mr.. Feely lost no
tine in putting electric light through
out his house and stables and about
his private grounds and utilizing the
new agency for various HOUSEHOLD and
farm purposes.
A SPECIAL DYNAMO.
The whole secret of the success of his
work is in the dynamo, which, in a
number Of ways, is different from the
usual electric dynamo. In an ordinary
dynamo the voltage depends upon the
speed with which IFS armature is driv-
en-, and it was found that owing to the
various speed at which the windmill
was driven, an ordinary dynamo would
be entirely useless for such purposes
IS MIR. Feely intended, hence it was
necessary to construct the special one.
In devising such a dynamo, three
things were essential. 1t must be self
regulating. free from all mechanical
coptrivances and above all it must be-
efficient.
