From The Collaborative International Dictionary of English v.0.48 :

  Grate \Grate\, v. t. [imp. & p. p. Grated; p. pr. & vb. n.
     To furnish with grates; to protect with a grating or
     crossbars; as, to grate a window.
     [1913 Webster]

From The Collaborative International Dictionary of English v.0.48 :

  Grating \Grat"ing\, n. [See 2d Grate.]
     1. A partition, covering, or frame of parallel or cross bars;
        a latticework resembling a window grate; as, the grating
        of a prison or convent.
        [1913 Webster]
     2. (Optics) A system of close equidistant parallel lines or
        bars, esp. lines ruled on a polished surface, used for
        producing spectra by diffraction; -- called also
        diffraction grating.
     Note: Gratings have been made with over 40,000 such lines to
           the inch, but those with a somewhat smaller number give
           the best definition. They are used, e. g., to produce
           monochromatic light for use in optical instruments such
           as spectrophotometers.
           [Webster 1913 Suppl.]
     3. pl. (Naut.) The strong wooden lattice used to cover a
        hatch, admitting light and air; also, a movable Lattice
