From the explanation the operation al
ready given evident that when the two
brushes are set that one leaves seg- 60
m t/' the instant that the other comes
in contact with segment the effect in
charging and discharging the condensers is
the same the previous instance. When brush breaks the
circuit through coil O', the high-potential dis-
25 charge kick” from the latter rushes into
and recharges the condenser N', but soon
as the brush has passed over the interven
ing block and reached the next segment d
it closes the circuit through coil and short-
30 circuits the condenser that high-fre
quency currents from either one the other
of the two condensers are flowing through the
primary practically without interruption. The
capability vaiying the relations the 65
brushes, however, which this form possesses
has the advantage permitting not only an
alternate charging and discharge the con
densers, but their simultaneous charging and
discharge multiple arc, whereby the fre- 70
quency the current discharge reduced. The combination with source elec
tric energy, plurality condensers and
a discharge-circuit therefor, motive device
and circuit-controller operated thereby and
adapted direct the energy the source 85
into the condensers and connect them with
the discharge-circuit successively and al

tric energy, motive device, two condens- 90

energy the source alternately into the said
condensers, and discharge-circuit through

troller one condenser discharges while the 95
