Abstract: A floor sweeper having a pair of rotatable brushes, each of which is alternately driven or freely rotatable over the floor. The direction of rotation of each brush is the same at all times and is opposite to the direction of rotation of the other brush. A coupling device is connected between a sweeper wheel and the end of each brush, and includes a hollow coupling wheel having an open inner end and cam risers on its inner circumferential surface. A pawl is mounted to be engaged by the risers. Means are provided to seal the interior of the coupling from dust and debris.
