Abstract
A brush holder mounted on a container of cleaning fluid includes clips engaging the handles of one or more brushes to support the brushes with the bristles thereof extending vertically into the cleaning fluid. Two vertically-spaced motor-driven cranks, rotatable in synchronism with each other about vertically spaced horizontal axes, have a horizontally extending crank pin, the lower crank pin being received in a hole in the brush holder, and the upper crank pin being received in a slot in the brush holder. The radii of the crank pins from their respective rotational axes are different so that, as the brush holder is driven up and down and side-wise by the eccentric action of the lower crank pin as it drives it respective portion of the brush holder, the brush holder portions above and below the lower crank pin are driven sideways for distances greater than the lateral excursions of the brush holder portion driven by the lower pin so that as the brushes in the holder are oscillated vertically, a rocking action is imparted to the brush and thereby to the bristles, with the lateral excursions of the distal portions of the bristles at the brush tip being less than those of the proximal portions of the bristles adjacent the brush heel.
