Abstract
An improved road scraper includes a second scraping device mounted at a rear end of a road scraper of a known construction having a first scraping device. Between the road scraper and the second scraping device are disposed a vertical displacement mechanism and a horizontal displacement mechanism. By the actions of these mechanisms, the second scraping device may be extended outwardly from one side of the road scraper for scraping a greater width of the road.
