(Chronoskop nach Hipp)
Description: A weight rotates a drum and starts the movement of
this primarily weight-driven timing mechanism. An electromagnet
releases the clutch which holds rotating hands away from the
turning drum and thus starts the rotation of the two measuring
hands. A second electromagnet causes the clutch to re-engage,
thus stopping the turning of the hands. Measurement of intervals
with a resolution of 1/1000 second is possible with proper
calibration, which is accomplished with devices like the
Kontrolhammer, No. 114. (Expanded caption Copyright 1998, Edward
