Mining machine with cutter drum having internal drive motors

A mining machine comprising:

• a mobile support;
• a boom carried by said support and having an elongated extent with one end of said elongated extent forming the central portion of an elongated forward end of said boom extending transversely of said elongated extent along an axis;
• said forward end including elongated support portions extending outwardly from longitudinally spaced portions of said central portion coaxially along said axis;
• rotary means supported by said central portion for coaxial rotation about said axis;
• cutting means driven through an orbital path by said rotary means to cut clearance for at least said central portion;
• an elongated drum cutter means supported by said support portions, respectively, for coaxial rotation about said axis to cut clearance for the remainder of said forward end;
• elongated energizable drive means supported entirely within said forward end and extending coaxially along said axis;
• said drive means having substantially its entire axial extent extending outwardly of said central portion;
• elongated rotatable shaft means extending coaxially along said axis through the axial extent of said drive means and having a rotary driving connection to said rotary means;
• and said drive means having rotatable driving connections adjacent the axially outer end thereof to said cutter drum means and said shaft means for driving said cutter drum means and said cutting means, respectively.
