227,247: 2 of 3

When used for sidewalk purposes, the upper surface of the skeleton-frame is formed with a series of lugs or roughened faces to prevent slipping, as shown.     Having thus described my invention, what I claim as new is--     1. A skylight composed of glass panes or blocks and a skeleton-frame arranged in the same plane with the glass panes, and constructed of detachable sectional bars, substantially as and for the purpose described.     2. The marginal frame A, having a groove

upon its inner edge, the long bars B, having corresponding grooves along their edges and tongues at their ends, the short bars C, having grooves along their edge and tongues at their ends, and the panes D, having tongues upon their four sides, all combined substantially as shown and described.
