(Trommel Kymographion nach Ludwig (Baltzar'sche Konstruktion))
DESCRIPTORS:
Description: This is a Baltzar-style kymograph (see Inside Cover,
Fig. 000c). Ludwig-Baltzar kymograph /A> the
standard variable-speed kymograph. The device has a spring motor,
and because the speed tends to increase in the beginning as well
as slow down when the spring is nearly finished, a speed
regulator is necessary. The spring can cause the drum to turn
from 2 seconds to 1.5 hours per revolution. The speed regulation
occurs with wind vanes, which have springs to prevent excursions
which are too wide. The apparatus is shown driving Meumann's
improvement of Wundt's time-sense (Zeitsinn) apparatus.
