Our invention relates to kmolds for tiles and it is an object ofthe invention to provide-l a mold or die whichl will in lone operation press or form the tile into shape and bevel the edges of the same, all as will be hereinafter more particularly described 1 and claimed.` y. s, l'

In order to limit the upward movement of the inner die boxunder theten-V sion of the spring 17, an elongated member 19 is fastened at each'end by meansv of screws ,M9215 FORTILES Y `Y 19281' seria Np.
