2	A.D. 1853.--Nº 1840.
Bellford's Improvements in the Combination of Glass with iron, &c. metal, and thereby prevent the liability to fracture of the glass. It consists in making rebates round the openings in the grating, which are large enough to receive the glass, with a band of packing or cement extending all around and under or inside it, and in making the sides of the glass and of the rebate of such form that when the packing or cement is in place the glass cannot be withdrawn.     The second part of my Invention relates to the employment of the combination of glass and metal above mentioned in structures where it is required to extend it over a larger area than is practically convenient with a grating consisting of a single casting. It consists in the employment of what may be either termed "panes" or "tiles," according to their position, of iron and glass in sashes or frames, either in an upright, inclined, or horizontal position, the said "panes" resembling the panes in an ordinary window sash, and the said "tiles" being placed in frames serving to make ornamental tesselated translucent pavement.     The accompanying Drawings illustrate my Invention in its varied applications.     Fig. 1, is a face view of four "panes" or "tiles" constructed by combining the glass and metal according to the first part, and inserted in a sash or frame according to the second part of my Invention.     Fig. 2, is a back view (on a larger scale than Fig. 1,) of one of the "panes" or "tiles" detached from the sash or frame.     Fig. 3, is the section of the same and part of its sash or frame.     Fig. 4, is a face or top view of a vault cover constructed according to my Invention.     Fig. 5, is a section of the same.     Fig. 6, is a back view of that form of glass light shown in Figs. 1, 2, & 3.     Fig. 7, is a front view of a light of a different form.     Fig. 8, and 9, are sections of Figs. 6, and 7.     Fig. 10, is a front view of a light of another form.     Fig. 11, is an edge view of the same.     Fig. 12, and 13, are front or top views of another form of light, the latter Fig. showing a metal packing ring round it.
