ING WITH THE ELECTRIC LIGHT
Thomas A. Edison is now engaged in max
ing some new experiments with electric currents. A
reporter OF THE TRIBUNE, who visited the workshop at
Meno Park N j. found the inventor at work with
apparatus which had been set up IN the building on the
previous day. IL was magneto-ele'tric machine made
by william Wallace OF AnsOnia, Conn. Mr.. Edison re-
Gently visited Mr. Walace's mandatory at AnsOnla,
and spent a day In examining the machines which have
been constructed thero Mr.. Wallace has manufactured
electrical instruments for several years aud has spet
much time and money IN perfecting magnetic
electric machine which he calls the tolemachon."
It's superiority other machines OF the same kind
consists mainly In nice adjustment Of the several parts,
and proper proportion between the fields OF force and
resistance Il produces enormous amount OF elec-
trcty for the force used in propeling It, As
I'm similar machines large electromagnetic are placed
with their poes facing each other, around moving axis
which carries other electr0magnets The moving mag
nets are armaturos wound with coils or wire and they
are made magnetic by the passage of electric currents
through the coils When the axis Is turned aud the coils
are made to pass large magnets currents Of
electricity flow through the coils, magnetic
ing the moving armatures and increasing the At
traction between them and the large magnets.
The flow OF electricity through the coils goes ON inoreas-
ing until the maximum Of magnetism has been reached.
Electricity is taken from the machine by OF
springs pressing upon break pieces attached to the
ing magnets on the axis. Mr.. Wallace has made his
chimes so perfect that nearly so per cent OF the
power used propong thom Is changed into electro
motive force. Tue excellence of the machine In this
respect makes IL valuable for transmitting power by
means OF electricity.
It was discovered some that when the elec-
trioity produced by magneto-eeotrlc machine was
made 10 pass into another tho axis OF the second
chino was made revove in opposite direction from
that in which the axis Of the machine producing the
electricity was propelled II is claimed by Mr.. Wallace
that when two OF his machines employed in this
way the power used to drive the first machine is repro
duced by the second with the loss Of only
80 per cent when an electric current is sent
through the wires connecting with the telemachon" +"
it charges the coils about the moving armatures, and
makes them strongly magnetic. They are at once at
traoted toward the large magnets Of the machine the
axis is turned Atthe time the break pieces the
axis are brought in contact with after another OF
the springs through which the electric current passes
the electricity In the coils is rearrauged and the moving
armaures are repelled from the large magnets which
had attracted them This constant change In the action
Of tile stationary and moving magnets each Other
causes the axis 10 revolye with increasing rapidly.
Mr. Edison said that the chief obstacle IN the way o.
