  • Patent number: 4335482
    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.

  • Patent number: 4062085
    Abstract: Suction cleaning apparatus such as a road cleaning machine comprises a closed chamber for receiving dust and similar matter together with liquid such as water intermingled therewith, the chamber having a suction duct thereto for taking up dust and similar matter from a road or like surface due to suction in the duct created by suction means such as a centrifugal fan communicating with the duct and chamber, return flow means or pipework being provided for passing water from the chamber to the suction duct for intermingling with dust or similar matter drawn into the duct. On discharge of the water laden with dust and similar matter from the duct into the chamber the laden water separates by reduction in velocity from the suction air flow while the water draining from dust and similar matter deposited in the chamber is re-circulated by the return flow means to the suction duct.
