Loosening dirt from carriageway surface - involves machine with scraper head with attached scrapers fixed on end of transverse rod

摘要

The machine to loosen stubborn dirt from a carriageway surface has several flexible, vertical to the road surface, scrapers all fixed to a scraper head (3). A bearer (2) holds the scraper head (3) on a transverse rod (1) so that it can slide along the rod or revolve. A ram (8) is connected to an arm fixed to the side of the bearer (2) and, against the power of a spring (9) forces the scraper head (3) outwards and downwards. A flexible member of constant length (10) leads the joint of the ram (8) through an arc. USE/ADVANTAGE - The scraper head can be raised from its working position to an upper position for transportation.
