t5 The regulator being properly adjusted,lights
or other devices may put out with
scarcely any perceptible difference. The combination, with the brushes, the
brush-holders and their axes, solenoid and
core, and connections move the brush-hold- '
ers, and dash-pot provided with valve,
substantially described, diminish the 45
speed movement the core one direc
tion more than the other, substantially set

2. 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.

It obvious that instead the dash-pot any
other retarding device may used. -
6. The combination, with the brushes, the
brush-holders and their axes, solenoid and 50
core, and connections move the brush-hold
ers, and dash-pot diminish the speed of
movement the core, substantially set
forth. This valve permits compara
