2. electrical system the kind de
scribed, the combination with the points or
terminals between which occurs the inter- 75
mittent oscillating discharge, means
for maintaining flow insulating liquid
between the discharge points, and means for
varying the length the path discharge
through such fluid, dependent for operation 80
upon the flow the same, set forth. 2. This accomplish in
the following manner:
A pipe tube that leads into tank
B.
If now the tank filled with oil and the
latter drawn off permitted flow off
2o through the tube the turbine will ro
tated the flow, the rate rotation being
dependent upon the rate flow.
Having now described invention and
the best means which aware which
the same may carried into effect, what
I claim is—
50 electric system the kind de
scribed, the combination with the points or
terminals between which occurs the inter
mittent oscillating discharge means for
maintaining between said points and the
path the discharge flow insulating 55
liquid, set forth. the end this tube secured ex
tension insulating material and the two
xo terminals are caused project through
the sides the same, indicated Fig. electrical system the kind de
scribed, the combination with transformer,
and the points terminals between which
occurs the intermittent oscillating dis- 60

forth. The combination with discharge points 90
immersed oil, means for causing flow of
the oil between said points and metallic
turbine mounted betw'een the points and

The flow oil regulated the speed at

Within the extension secure two cross-bars
H which afford bearings for the spindle a
small metallic turbine the blades which,
i5 the turbine revolves, bridge the space be
tween the two terminals, nearly quite
touching the terminals their movement.
When necessary desirable may insert
in the pipe coil which contained in

is passed.
The further objects the invention are se
cured placing the transformer the
body oil the tank and the condenser
30 closed receptacle Then order to
■maintain circulation the oil and pro
vide for the requisite flow which rotates the
turbine, connect the tank with the con
denser box means the pipe also
35 run pipe from the box small ro
tary pump and another pipe from the
latter back the tank B. The combination with discharge points
immersed oil, conductor adapted pe
riodically bridge the space between such
points, set forth. this
means the arc discharge periodically es
tablished through flowof oil, which secures
25 the most satisfactory manner the condi
