IN THE ELECTaICAL WORLD.

The Direction of improvements In Street
1T mas been estimated Jnat about $50
electric railways are in operation, or
actually under construction, in this
country at the present time. The mile
age is probably about 5000, and
the number of cars about $500.
The efforts of the manufacturers
of electric street railway motors
this year have been toward the
reduction of the speed of motors. Near
ly all have made single gear motors, and
two have devised gearless motors. A
single storage battery road has been
put in Liberation within year. Reports
OF the trials OF single gear motors are
that they start well on grades, do not
heat much, seem to take about the same
current as the old machines,
unless possibly a little more
at starting, and can perform the
heaviest services satisfactorily. The
indications Of the coming Improvements,
according to the Electrical World, are
in the direction of gearless motors, the
increased use Of long and capacious cars
on large roads, and the displacement OF
small and wasteful engines.
Dobrowolsky, the inventor and de-
slgner of the electrical transmission
plant at the International Electro
Technical Exhibition at Frankfort, is
willing to attempt to transmit either
1000 or 5000 horse power Niagara to
Chicago. The distance being about 500
miles, between 10000 and $4,000 volts
would be required. OF 5000 horse
power operated at Niagara about 5000
could be utilized at Chicago.
An elevator that is operated by cleo
tricity on a new principle has been test
en- In Brooklyn. 1t is controlled by a
handle within the car, and the motion
can be increased or decreased in speed
or reversed.
If a company can get control Of water
power OF 10000 horse power at Barnett
Shoals it proposes to run by electricity
the machinery in every mandatory in
Athens, Ga.
A project has been started in Pueblo,
COL, for the erection OF an electric
smelling plant to cost 100000, for the
reduction by electricity OfadrV and re-
fractory ores.
A new resistance metal resembles or
binary copper wire on the outside, with
q pinkish white tinge at the point of
fracture. It's very strong without los
ing much ductility.
For preventing the vibration OF the
In incandescent lamps in cleo
trio railway cars, new lamp has the
loop of the filament held by short loop
Of carbon sealed to the top Of the butts.
The managers of electric railway com
NAMES are praying for the ideal light
ming arrester that will effectively pro-
tect their dynamos.
A new electric soldering iron has q
wire, forming part of an electric circuit,
wound in concentric helices, which are
by strips OF insulating materi-
al. with an enclosing casing and a sold
ering point in close proximity so as to
be heated thereby.
A core for smoothing irons, to be
heated by electricity, is one Of the new
things, in combination with wire form
ing part of an electric circuit and wound
In a heating coil or spiral. The core is
solid and of insulating material, which
IS grooved TO receive the wire and has a
permitting the return Of the
wire TO the end OF the core at the be-
Of the winding.
At the central power station Of the
West End Railway Company, in Boston,
the boilers are TO have capacity OF
"a. 900 horse power. The chimney is
o52 feet in height, with cast iron cap
weighing s,4OO pounds. Each Of the
thirteen triple expansion engines Of p
300 horse power will have flywheel 2s
feet in diameter. 10 feet and inches
faces, and weighing so tons. Each en-
CINE will run four generators. Two en-
zines have been started.
