channel irons; and the diameter of the lower portion of each lens or light is sufficient to enable it to extend well over upon the bottom of the channel irons beyond the margin of the opening 11 it is adapted to cover, as shown in Fig. 2; and the bottom of each lens or light is provided with a recess corresponding in shape and size to the opening 11 over which it is placed as is likewise shown in Fig. 2, is forming thereby bottom flanges 15, the inner wall of which will be flush with the margin of the opening. When the lights or lenses are in position a filling 16 of cement or other desired material is placed in the space between the lenses and is carried flush with the upper faces thereof, and flush with the upper edges of the outer angle irons B, which angle irons are made to extend up a suitable distance beyond the flanges of the channel irons, and the shoulders produced in the lenses or lights, by reason of their being made in two diameters, will afford a sufficient bearing for the filling in material to enable the latter to hold the lenses firmly in place.     It will be understood that the arrangement of the lights or lenses may be as fancy may dictate.     A vault light constructed as above set forth may be not only expeditiously but exceedingly economically made, since all the material employed is stock material, and it may be

connected or built up in a manner enabling the vault light to be applied wherever such an article is necessary.     Having thus described my invention, I claim as new and desire to secure by Letters Patent--     1. In a vault light, a lens support consisting of channel irons placed side by side and connected, the channel irons being provided with apertures between their flanges, and lenses adapted to cover the apertures in the channel irons, said lenses engaging with the flanges of the channel irons, as and for the purpose set forth.     2. In a vault light, the combination, with a lens support consisting of a series of connected channel irons provided with openings between their flanges, and a framing of angle irons receiving the said lens support and secured thereto, the attached members of the framing extending above and below the lens support, of lenses adapted to cover the openings in the channel irons, the spaces between the lenses being adapted to be filled with a cement material, and braces attached to the framing and engaging with the under surface of the channel irons or lens support, as specified.
