Abstract:
1. Apparatus for removing metal cuttings from a flowing liquid stream of oil well drilling mud, comprising: a) a bar having a first end portion that is a magnetic section, a second end portion that is a non-magnetic section, an outer surface, and wherein said bar has a generally uniform cross section; b) a first end plate attached to one end portion and having a peripheral portion extending radially away from the bar; c) a second end plated attached to the second end of the magnetized bar with a connection that enables the second end plate to be quickly disconnected from the bar, the second end plate having a peripheral portion extending radially away from the bar; d) a non-magnetic wiper plate having an opening that closely conforms to the outer surface of the bar, the wiper plate and bar defining an assembly, the wiper plate being slidable upon the bar between the end portions so that movement of the wiper plate from the magnetic section to the non-magnetic section effects removal of metal cuttings from the bar by pushing the metal cuttings from the outer surface of the bar next to the magnetic section to the outer surface of the bar next to the non-magnetic section; e) one or more handles on the wiper plate that enable a user to manipulate said assembly; and f) wherein at least one of said handles is in a peripheral portion of the wiper plate.
