Abstract
Abstract An electric coupling control for a multiple spindle automatic machine is disclosed with the machine having an indexable spindle carrier with a plurality of rotatable spindles. An electric clutch and brake unit is provided for each spindle and the clutch or the brake is selectively energized through a brush and commutator assembly so that selectively either the clutch or the brake may be engaged for a particular spindle for each spindle position of the spindle carrier. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
