Abstract

1441391 Windscreen cleaning systems J S SMITH 26 June 1973 [26 June 1972] 29749/72 Heading A4F [Also in Divisions B7 E2 and F1] A fluid operated drive assembly 2 for a windscreen wiper 1 comprises a tubular support 8 having two opposed walls 10 and 12, and a flexible structure such as a tube 11 extending along the support 8 and defining driving zones on each side of a roller assembly (for connection to the windscreen wiper 1) comprising three rollers 4, 5, 6 running along the walls 10 and 12 and thus flattening tube 11 at the region of engagement therewith. Selective application of fluid-pressure to the driving zones within the tube 11, by control means including a distributer valve assembly (15), Figs. 4 and 5 (not shown), propels the roller assembly along the tubular support 8. In the embodiment of Fig. 3, a side wall of the support 8 has an elongate opening through which the wiper 1 extends for movement to-and-fro across a windscreen. In Fig. 6, fluid exhausted from a driving zone of the drive assembly is supplied via a flexible tube 27 to a hollow wiper support which has outlets 28 spaced along its length so that the fluid (water) assists in cleaning of the windscreen.
