offering little or no obstruction to the light, can be placed wherever it is found necessary.     My improved bearing-beam or cross-bar is applicable for any kind of illuminating-tiles, roof-lights, vault-lights, floor-lights, &c., and for either "concrete" or "knob" tiles.     I do not claim, broadly, the construction of tiles or gratings having half light-openings along their edges, which form whole light-openings when in junction with each other.     What I claim as new, and desire to secure by Letters Patent, is--     1. The combination of illuminating-tiles having half light-openings along their sides or

edges, with a cross-bar or bearing-beam made in a corrugated form, so as to pass beneath the uniting edges, and partly around the full light-openings thus formed, substantially as described, and for the purpose set forth.     2. A cross-bar or bearing-beam for illuminating-tiles, made in a corrugated form, the corrugations being oblique from the top downward, substantially as described, and for the purpose set forth. THEODORE SHARTS. Witnesses:     RO. L. CLUTTER,     GIOVANNI TRAPONI.
