To all whom may concern:
Be known that Nikola Tesla, the
borough ofManhattan,in the city, county,and
State New York,have invented certain new
S and useful Improvements Electrical-Cir
cuit Controllers, which the following a
specification, reference being had the draw
ing accompanying and forming part the
same.
In the drawing hereto annexed have illus- 55
trated the preferred form apparatus which
I have devised for carrying out these improve
ments. For example, order effect rap-
idly-intermittent contact between two termi
nals the use jet jets closed re-

These two parts are electrically connected,

The present invention embodied de

curing, among other things,an approximately
constant relative movement between the
parts, feature which devices this kind
is often very desirable.
