Abstract
An improved method and apparatus for removing metal cuttings from an oil well drilling mud stream provides a magnetic body or “ditch magnet” having end plates that extend radially and circumferentially from the magnetic body, the plates being positioned at end portions of the magnetic body. A third plate in the form of a wiper is used to dislodge metal cuttings and other metallic material from the magnetic body after the magnetic body has accumulated such metallic parts. One of the end plates can be removable to facilitate a complete scraping or wiping of the metallic parts from the metallic body by the wiper plate.
