GUIDE RAIL ASSEMBLY FOR THE EJECTOR OF A SCRAPER AND METHOD A B S T R A C T A scraper comprises a bowl structure having an ejector assembly reciprocally mounted thereon for selectively discharging material forwardly of the bowl structure. In one embodiment, a guide rail assembly is secured interiorly on each sidewall of the bowl structure to engage a guide roller, rotatably mounted on the ejector, for guiding the same during its movements in the bowl. Each guide rail assembly comprises a cylindrical guide rod secured on a respective sidewall by a pair of locating rods disposed on either side of the guide rod and welded between the guide rod and the sidewall. The guide rod is secured to the sidewall of the bowl structure by placing a first linear portion thereof adjacent to the sidewall and then placing first linear portions of the locating rods on either side of the guide rod to space it from the sidewall at a first predetermined distance. This procedure is followed along the entire lenghts of the guide and locating rods to compensate for any irregularities that may be formed in the sidewall whereafter the located rods are welded between the guide rod and the sidewall. In a second embodiment, the guide rail assemblies are secured to a push frame of the bowl structure to engage guide rollers rotatably mounted on a rear- ward extension of the ejector assembly.
