As the lever is depressed by a user the bi-directional gear of the drive mechanism is engaged and a length of paper towel is dispensed. When the user releases the lever, the bi-directional gear is returned to its start position by a spring. On the return stroke the spring drives the bi-directional gear and dispenses an additional length of paper towel.
