NIKOLA TESLA. Such arrange
ment has the advantage that great number
of lights may put without diminishing
the light-power the lamps the circuit, as
the brushes assume once the proper position,
io When lights are cut out, the dash pot acts to
retard the movement; but the current is
considerably increased the solenoid gets ab
normally strong and the brushes are shifted in
stantly. The combination, with the brushes, the
brush-holders and their axes, solenoid and 50
core, and connections move the brush-hold

movement the core, substantially set
forth. The combination, with the brush-holders 55
and the solenoid and core, links connecting
