Abstract
A rotary brush mounting comprises support structure mountable from a sweeping machine and carrying support means for angular movement about pivotal axes at right angles to one another in a universal manner and a driven rotary brush depending from the support means and normally rotatable about a substantially vertical axis but capable of sideways and back and forth inclining movement with the support means so as to follow varying formation or irregularities of a road or similar surface in order to maintain effective sweeping contact therewith. The support structure may consist of a bracket having a pivoted arm extending for swinging movement and carrying the support means which latter may consist of a forked member longitudinally pivoted on the arm and carrying between its limbs for transverse pivotal movement a support member for the brush together with a direct motor drive to the latter. Universal pivotal movement of the support means may be damped and also spring urged to the normally upright position of the brush. Swinging movement of the pivoted arm of the support structure may be also damped.
