Abstract
17,819. Sheldrake, J. H. July 29. Incandescent gas lamps.-Relates to lamps for street and outdoor use generally. In the upper part of the lantern is placed an inverted reflector, from the centre of which rises a tube C. The products escape through this tube, downdraughts b e i n g prevented by cones E. The gas pipe F is carried well up into the lantern, and has an enlargement G in which are provided air inlets. The upper end of the mantle is within the tube C or is near thereto. A cone J, which may be transparent, directs air against the exterior of the mantle. A burner, carrying the reflector and other fittings described above, may be screwed into the place of the nipple in any ordinary street or outside lantern.
