We present two infinite classes of links and prove their fiberedness. The grid diagrams are used for combinatorial description. The first class generalizes the Lorentz links and is characterized by the fact that every second vertex in the diagram of each representative of the family lies on the coordinate diagonal of the grid diagram. The complements of the knots of the second class admit a free action of a"e (n) .
