Abstract

549,187. Earth-scrapers. KOEHRING CO. Nov. 6, 1941, No. 14321. Convention date, Jan. 27. [Class 68 (i)] In an earth-scraper in which the scraper blade 5 is carried by the body 3 and raised or lowered thereby, and a rear apron 6 is pivoted at 7 behind the blade and moved by a cable 8 between earth-carrying and dumping positions, the apron is provided at its edges with scraper plates 12 which bear against the inner sides of the body and are held to the apron by bolt and slot connections to permit taking-up of wear. Where a front apron, mounted in reverse position, is provided, such apron may be similarly provided with plates 12.
