Abstract: Brushholder apparatus is disclosed for supporting electrically conductive brushes of a dynamoelectric machine in a manner facilitating improved cooling of the brushes and adjacent collector ring. The apparatus includes a brushholder assembly with a pair of legs to internally support a brush and may also include a casing arranged to retain several brushholder assemblies, provide an enclosure for properly directing cooling gas circulated by a fan, and furnish a common electrical link between brushholder assemblies and a source of electric current. An insulated handle is described which can be inserted into the brushholder assembly and manipulated to lock handle, brushholder assembly, and brush together as a unit to permit safe removal of the brushholder assembly and associated brush from the casing and installation of a new brush during operation of the machine.
