Drain cleaning machine

A drain cleaning machine for moving a snake in a drain, the drain cleaning machine comprising:

• a rotating shell;
• a motor switchable between an activated state, in which the motor rotates the rotating shell about a snake axis along which the snake is configured to be arranged, and a deactivated state;
• a radial drive mechanism coupled for rotation with the rotating shell and including a plurality of collets, one or more of the collets being moveable toward the snake axis, the radial drive mechanism switchable between an engaged state, in which the one or more of the collets move toward the snake axis to engage the snake, and a disengaged state, in which the one or more of the collets move away from the snake axis;
• a translate mechanism coupled for rotation with the rotating shell and including a plurality of wheels, one or more of the wheels being moveable toward the snake axis, the translate mechanism switchable between an engaged state, in which the one or more of the wheels move toward the snake axis to engage the snake, and a disengaged state, in which the one or more of the wheels move away from the snake axis;
• and
• a selection mechanism configured to switch the radial drive mechanism from the disengaged state to the engaged state and configured to switch the translate mechanism from the disengaged state to the engaged state,
• wherein when the radial drive mechanism is switched to the engaged state by the selection mechanism, the translate mechanism is in the disengaged state,
• wherein when the translate mechanism is switched to the engaged state by the selection mechanism, the radial drive mechanism is in the disengaged state,
• wherein when the radial drive mechanism is in the engaged state and the rotating shell rotates about the snake axis, the collets engage the snake to rotate the snake about the snake axis,
• wherein when the translate mechanism is in the engaged state and the rotating shell rotates about the snake axis, the wheels engage the snake to move the snake along the snake axis.
