| titleOfInvention | Switching apparatus for a machine responsive to a source of dc power |
| abstract | ABSTRACT OF THE DISCLOSURE A switching apparatus for a machine responsive to a source of DC power, the apparatus having first and second annular brush rings associated with a rotor and first and second brush devices associated with a stator for respectively coupling the first and second brush rings to opposite polarities of a DC source. A first roller contact is associated with the rotor and is electrically connected to the first brush ring for progressively and sequentially engaging commutator bars to thereby momentarily couple the commutator bars to the first brush ring. A second roller contact is associated with the rotor and is electrically connected to the second brush ring for progressively and sequentially engaging the commutator bars to thereby momentarily couple the commutator bars to the second brush ring. The first and second roller contacts have contoured outer surfaces adapted to mate with the complementary contoured inner surfaces of the commutator bars. |
