NEW AND NOVEL INVENTION.
Conveying Water Power Over Wires by
the Use of Electricity..A Wonderful
Instrument.


the Use of Electricity.-A Wonderful
Instrument.
Professors Edison, Barker and others
have returned to New York from An
sonia. n. H., full Of praise Of a wonder
full invention by William Wallace. Mr..
Edison believes that he can so assist Mr..
Wallace in perfecting what he calls "the
telemachon," that power may be trans
mitted from one point to another as
though it were telegraphic message.
Already, by means Of this instrument,
Mr.. Wallace is enabled to transmit the
power Of the Naugatuck river quarter
Of u mile. The power Of this steam il
great enough to drive the ponderous
machinery Of the Wallace factory,
where 800 men are employed. A
series Of experiments with the instru-
ment has shown that in the transmits
sion Of this enormous power by cleo
tricity only 70 per cent. il lost. In
this instrument the electricity is pro-
duced by the Wallace dynameletric
machine, no battery being used Four
large electromagnetic are placed with
their poles facing each other. On an
axis, parallel with and situated be-
tween them, is disc Of iron, carrying
upon its opposite face a row of electro
magnets, 80 in number. These rcyolve
as close us possible to the poles Of the
large magnets, called the "field Of force"
On the same axis, but outside Of these
discs, strips of copper are placed, equal
in number to the magnets on the dies,
each strip Of copper being connected
to one end Of the wire goes to the next
strip. Each strip, therefore, is connect
ed to the last end Of the coils and to
the first end OF that Immediately fol-
lowed it. When the disc with its mag
nets is rcyolvcd by any power, the
weak magnetism remaining in the iron
itself generates II current OF electricity
IN the wire surrounding those magnets
In virtue Of the principle discovered by
Farraday, that whenever IL conducting
wire is moved III the vicinity Of mag
net u current Of electricity Is caused to
circulate in that wire, the feeble current
thus generated flows around the mag
nets Of the field Of force, increasing
their magnetism. This increased cleo
tricity reacts upon the revolving mag
nets, increases the electric current and
SO, alternately until the magnetism at
tainS u maximum and that maximum
is generated in the wires of the revolv-
ing magnets. This current bears for
each perfectly definite ratio 70 the
power consumed, and they are capable
of converting 50 per cent. Of the power
applied into electricity. The electric
current generated is carried by two cop.
per wires to II second machine, the tele-
machon. This effects the reverse opcr-
atoms that is to say the reconversion Of
the electricity into mechanical power
Tho tclemachOn consists of field of
force and u revolving armature. This
field of force consists Of twelve large
electromagnetic in two sets Of six each
the poles ofcach facing each other and
connected together by heavy bands or
bridges. In the space enclosed BY
these magnets, and parallel with them,
is tho armature axis, supporting I'M ar-
mature, consisting Of ring of iron
wire, serving us u core, around which is
wound i'm insulated copper Wire in two
series OF Seconds. The ends Of these
wires come out alternately to the right
and left Of the armatrre and are con-
nectcd with two break pieces upon
their axis. Six springs, or brushes of
copper wire, press upon these break
pieces, each pair ofbrushes facing each
other and opposite II pair of magnets III
the field Of force. The electric current,
entering the machine, passes round the
field Of force and magnetizes the mag
nets. AT the same time it passes
through the armature, magnetizing that
50 that the poles Of the armatlre near
est to the poles of the field magnets are
of opposite nature. In consequence of
this, the field Of rorce magnets attract
the poles Of the armatmc and causes
the armaturc to move. But the motion
III its new position brings other portions
Of the break pieces III contact with the
springs, and causes redistribution of
the magnetism. Again, attraction takes
place rs before, and again the direction
Of the current is changed by the break
pieces. The magnetic effect being con-
tinuous, increasing constantly IN speed
until the friction and magnetic power
balance each other.
