Screw jack assembly for paving machine

A paving machine comprising:

• a chassis;
• a tow arm pivotally coupled to the chassis;
• a screed assembly pivotally coupled to the tow arm, the screed assembly having a frame and at least one side gate movably disposed on the frame;
• and
• at least one screw jack assembly operably coupled to the at least one side gate, the at least one screw jack assembly including:
• a first body defining a longitudinal axis and fixedly coupled to the frame;
• a screw drive rotatably disposed within the first body and axially aligned along the longitudinal axis, the screw drive defining a first end and a second end;
• a second body movable relative to the first body along the longitudinal axis and operably coupled to each of the screw drive and the at least one side gate;
• a first gear coupled to the first end of the screw drive;
• and
• a handle assembly including:
• a tube member movably coupled to the first body and axially aligned along the longitudinal axis;
• a second gear disposed within the tube member and operably coupled to the first gear;
• and
• a handle member fixedly coupled to the second gear and adapted to rotate about a rotational axis substantially perpendicular to the longitudinal axis,
• wherein the handle member is adapted to selectively rotate between an operating position and a stowed position about the longitudinal axis based, at least in part, on rotation of the tube member relative to the first body along the longitudinal axis.
