Abstract

A magnetic device for picking up ferrous metal debris, such as nails, screws, sheet metal fragments, staples, rivets, and other ferrous metal objects from an environmental surface such as the ground or a floor by rolling along the surface, consists of: a magnetic pickup member; a pair of wheels mounted to the magnetic pickup member and supporting the magnetic pickup member slightly above the environmental surface; a handle; a wiper for scraping ferrous metal debris from the magnetic pickup member and biased against the magnetic pickup member; and a release rope for rotating the magnetic pickup member against the wiper, thereby dislocating ferrous metal debris from the magnetic pickup member. Optionally, a hopper may be attached to the device for receiving the ferrous metal debris.
