gy transmitted BY thecoal iuto steam,
through the engine into electric en-.
ergy, which produces light, II Is read
lily seen that this enormous loss OF
heat was great disadvantage. Ia
this connection lt Is seen that the
Brush machine transforms ninety per
cent of the mechanical energy Of lthe
engine into electric current, and 81
per cent of this Is available for lights.
Besides great loss in heat and other
wise by the old machines, there was
d still greater disadvantage arising
from the fact that each light required
circuit Of Itself. As II requires two
wires to make Il circuit from the ma
chine to the light, 1t will be seen that
the great multiplicity oil wires also
multiplied tho resistance, and conse-
quent lots of energy in keeping up q
great number of circuits. The Brush
machine overcomes these many dis
advantages in the very large per cent
age of energy transformed, and In
the fact that as many lights as de-
sired may be operated on one circuit.
From forty to fifty would be about as
many as could be advantagoously
supplied on one circuit, however.
The little machine In the station
when standing still, may be easily
moved by one hand. 1t presents,
really, no resistance. The "arma-
ture" which revolves between the
magnets, Is tlat wheel, with a sur
face about two inches wide. divided
by series Of grooves running around
the ring, and separated into sections
by eight wound bobbins projecting
from the surface. This wheel when
the machine Is at rest, handles like
a lsose pulley, and the space on each
side between 1t and the magnets, Is
about one-eighth Of an inch. When
the engine slowly starts singular
phenomenon Is noticed. AS the mum
Der Of revolutions increases, that
apparently loose wheel gradually
tightens up and grinding sound Is
heard, although there Is absolutely
no friction. The resistance between
the armature and magnets gradually
becomes so great that the full fourteen
horse power Is required to reach 75O
revolutions per minute. Stop the
engine and the lights go out, and
the armament which is Faraday's
wire increased many fold, may be
easily moved with one finger. When
the machine Is in motion at a high
rate Of speed and the magnetic field
Is enormous, a sheet OF paper can be
easily passed between the wheel aud
magnets without any perceptible ef-
feet. BY means of brushes and cop.
per wires the electricity Is gathered
and sent out on the wire 10 the cir
cult of lamps, and returns from the
last lamp again to the machine, form
Ing complete circuit. Having got
the current flowing in tho circuit, the
point Is to get"it TO manifest itself.
This is done by inserting In the lamps
the carbons elsewhere described
These points OF carbon are separated
by the force Of the current. The sep
aration Of the carbon causes slow
volatiliZation and consumption OF the
points. II the copper wires were
simply separated without tho use oi
the carbons the light would be pro-
duced the same, but IL would be a
green light, aud less intense and less
concentrated.
The carbonic sticks being copper
coated, il renders them faithful con-
ductors of electricity, land confines the
electric energy (current) at the point,
and all the energy Is saved and trans
mitted, not consumed in tho light.
The purpose of the company in es-
tablishing this station Is to provide q
means of producing and distributing
electricity for light, and for other
purposes, in such quantity and time
as the user may need. 1t is intend
ed to provide a system OF practical
lighting similar TO gas works. II
is proposed to charge Customers Il
certain amount per day or hour,which
can be determined by the consump-
tion of the carbens. The light 50
furnished could be readily turned on
or off. Lighting stations similar TO
this are in operation in New York,
San Francisco, Detroit and Grand
Rapids others are being established
In cities and towns everywhere. The
number OF large mills, factories,
shops, ETC., in which the light il
used is very numerous and rapidly
increasing. The company began put
ting up lights two and a half years
ago, and have now in operation over
1900 lights, and the saving can be
imagined from the fact that the Riv-
erside Worsted mills of Providence,
r. l., formerly used other light al
an expense of $2S. .S08 per year. They
now use about 100 electric lights, and
have every part of their mills better
illuminated at an expense OF $4,000
for 5000 hours per year. A large
number OF other instances might be
cited of the economy Of this light.
After the Bush electric works,
which stood off the corner Of Ontario
and st. Clair streets, were burned the
company resumed their operations al
the extensive buildings they now oc-
cupy, near the Euclid avenue station
on the Cleveland and Pittsburg road.
Two hundred and seventy five men
are now employed in the various de-
partments of the establishment, an
increase of 175 since last year at this
time. Upon entering the manufac-
tory one is struck with the stir that
is seen on every side. The buildings
are crowded to overflowing with ma
chinerY and man. and every inch al
