Claims4
A magnetic filter adapted to be selectively mounted on an oil filter canister employed in a vehicle, or on the vehicle transmission oil pan comprising a cup, said cup having a bottom wall and an integral side wall, an outwardly extending flange integral with an upper peripheral edge of the side wall, an annular disc supported on the bottom wall of said cup, an annular magnet supported on said annular disc, said annular magnet being substantially coplanar with said outwardly extending flange, means extending through said magnet and said disc for holding the magnet and disc in a centered position within said cup, and a suction cup connected to said outwardly extending flange for selectively connecting the cup and magnet to a surface of the oil filter canister or vehicle transmission pan, whereby the suction cup not only holds the magnetic filter on the surface, but also prevents dust and debris from entering the cup.
A magnetic filter adapted to be selectively mounted on an oil filter canister employed in a vehicle, or on the vehicle transmission oil pan comprising a cup, having a bottom wall and an integral side wall, an outwardly extending flange integral with the upper peripheral edge of the side wall, a plurality of circumferentially spaced apertures provided in said outwardly extending flange, and a rubber suction cup having a portion thereof extending through said apertures connecting the suction cup to said outwardly extending flange, whereby the cup and magnet can be selectively connected to a surface of the oil filter canister or vehicle transmission so that the suction cup not only holds the magnetic filter on the surface, but also prevents dust and debris from entering the cup.
