A self-propelled road sweeper has brush gear comprising a narrow sweep brush and a wide sweep brush, together with an associated refuse collecting nozzle. The narrow sweep brush is mounted on a linkage comprising pivotally connected inner and outer mounting links and controlled by pneumatic actuators whereby the position of the brush and its downward loading is controlled. The brush can be tilted by one of said actuators. One of the mounting links is connected to the sweeper frame through a resilient mounting permitting the brush to yield under impact. The application also discloses details of the mounting and structure of the wide sweep brush, and of the mounting and fabrication of the nozzle and of a mechanism for tilting the nozzle.

Road sweeping apparatus comprising: a frame or body; a brush and mounting and drive means therefor whereby the brush is rotatable to effect sweeping in the region of one side of the apparatus; a refuse tank; refuse collecting and transfer means associated with the brush to collect material swept by the brush and to transfer the material to the tank; the mounting means for mounting the brush on the frame or body comprising: an inner mounting link; an outer mounting link; and actuating means for said links; the inner mounting link being connected at its inner end to the frame or body and being pivotally connected at its outer end to the adjacent end of the outer mounting link; the outer mounting link being connected at its outer end to the brush; and the actuating means being connected to said links and being operable to cause angular movement of the links relative to each other whereby the linkage formed thereby extends and retracts moving the brush inwards and outwards relative to the frame.
