To identify Bradley and Hubbard pieces, it’s usually necessary to use the characteristics of the lamp to make an identification: The shade construction was patented in 1905 and in 1908. Crooke, assigned to Bradley and Hubbard utility patents: #. 0796193, 8/01/1905 & #0901690, 10/20/1908. The 1905 patent related to an. Improvement in the construction of lamp shades of the type that used colored. Or stained glass to create scenes or designs. Crooke explained the problem. With traditional leaded glass shades: this method of producing lamp shades is. Not only very expensive, but is open to objection that in case a piece of glass is. Cracked or broken it cannot ordinarily be replaced except by returning it to the. Maker of it or sending it to an expert in the art. The object of this invention. Was to produce, at a greatly reduced cost for production, a shade from one. Piece of metal in imitation of the leading of traditional stained glass panels. That would enable the easy replacement of broken glass and give great. Freedom to the designer. The innovation consisted of separate panels, in this. Case to form a hexagonal shade when assembled, cast with a design and in. One piece from soft metal. The frame pieces, “L” shaped in section, had metal. Tabs attached to the back which held the glass in place. Related to: an improvement on his patent #0796193. The patent consisted of metal tabs at the corners that secured the glass as. Well as casting the parts of the scene in three dimensional relief. Please see: Bradley and Hubbard Manufacturing Co.
