Abstract

A hand operated magnetic sweeper comprises a longitudinally elongated, reinforced body member molded in one piece of non-magnetic material with wheels mounted for rotation on the longitudinal ends thereof, the body including a handle socket on its top side arranged to support a handle for angular extension vertically upward and rearward therefrom. The body is configured with longitudinally extending magnet holding pockets arranged along its longitudinal centerline so that magnets contained therein have a pair of adjacent perpendicular surfaces disposed at different distances from the circumference of the wheels, whereby each of said surfaces may be positioned to face downward toward an underlying surface by rotation of the body through 90.degree. relative to the surface. A brush is mounted to the rear edge of the body for sweeping contact with a surface when the sweeper is rolled over the surface.

Dependent claims

A magnetic sweeper, comprising:

(a) a transversely elongated, unitary non-magnetic body having an outwardly projecting handle member centrally mounted on its top surface,
(b) the body configured with at least one magnet retaining pocket on each side of the handle, each pcoket having an open side for removable reception of a permanent magnet,
(c) each magnet configured with one side surface having a given area and a second side surface disposed 90 degrees relative to the first side and having a larger surface area, and
(d) wheels on the opposite ends of the body mounted for rotation on a transverse axis,
(e) the pockets on said body arranged to support said one side surface of each magnet a predetermined distance inward of the outer circumference of the wheels and the second, larger side surface a predetermined greater distance inward of the outer circumference of the wheels, whereby in one position of the body the said one side surfaces of the magnets are positioned in a predetermined distance above and facing an underlying surface to be swept, and in a second position of the body, rotated 90 degrees from said first position, the said larger second side surface of the magnets are positioned a predetermined greater distance above and facing an underlying surface to be swept.
