Abstract:
1. A rod scraper for cleaning a translating cylindrical rod, the rod scraper comprising: a scraper ring having a center opening for passing a cylindrical rod and having an interior scraping edge for removing foreign material from the cylindrical rod as the cylindrical rod is moved relative to the scraper ring; and an annular scraper housing adapted for mounting to a stationary support for the cylindrical rod and having a center opening for passing the cylindrical rod, the annular scraper housing having a lower surface to receive an upper flange on the scraper ring and hold the scraper ring in position between the annular scraper housing and the cylindrical rod; wherein the scraper ring and the annular scraper housing are each formed in two connectable portions so that the rod scraper can be assembled around the cylindrical rod without sliding the annular scraper housing or the scraper ring over an end of the cylindrical rod; and wherein the annular scraper housing holds the scraper ring and prevents the scraper ring from translating axially relative to the annular scraper housing while allowing the scraper ring to translate radially relative to the annular scraper housing.
