The machines run by this transmission consist of the looms of Rieter &
Co., of Winterthur; the large flour mill and lift of A. Millot & Co.;
the flour milling machinery of Frederick Wegmann & Co., of Zurich; the
brick and tile making machines of the Rorschach foundries; and the
looms of Messrs. Houget & Teston, of Verviers, in the Belgian section.
A 15 horse power two-pole Oerlikon dynamo is also run by a belt from
the main shaft, and generates power to drive a motor of similar type
in the Swiss section of the upper gallery. This runs a length of
countershafting supplying power to three silk-weaving machines
constructed by Benninger Freres; six weaving machines from the Ruti
works, near Zurich; and one knitting machine exhibited by Edward
Dubied & Co., of Couvet.
The dynamo and motor are connected to the main cable by switches of
the type shown in Fig. 5. These are specially designed to destroy the
extra current on breaking circuit by the formation of an arc which
gradually increases the resistance till the break occurs, rendering it
less sudden. One wire passes through the handle and makes contact with
the springs, and the other is attached to the clamp in which the
carbon rod is held. The current is made to enter at the carbon rod, so
that the arcs formed cause consumption of the carbon. A magnetic
