Abstract
1,071,007. Earth-moving bowl type scrapers. CATERPILLAR TRACTOR CO. Nov. 8, 1965 [Dec. 2, 1964], No. 47173/65. Heading E1F. On each earth-moving bowl scraper for tandem-operating scrapers controls are provided for regulating movement of the movable parts of the scraper and in addition on the leading scraper further controls are provided for actuating the controls of the rear scraper only or the controls of both scrapers simultaneously. Specification 983,655 is referred to.
