label: Description (Brief)
content: Designed by Weston. This is an early type of direct current dynamo. The laminated armature has a drum-type winding. The field magnets are of the horseshoe type. The pole pieces are divided into sections by a series of vertical slots, in order to decrease eddy currents and give better air circulations. Brushes are of the carbon type. Both are in need of replacement. Rigging is slightly bent. Commutator is badly scared. Oil cups for shaft lubrication are missing. Reference: Urquhart, Electric Light, pages 141-144.
