    Regulating the Temperature of Vulcanizing Apparatus. (This Invention received Provisional Protection only.) PROVISIONAL SPECIFICATION left by Alexander Jamieson at the Office of the Commissioners of Patents, with his Petition, on the 12th May 1873. I, Alexander Jamieson, of Broad Street, Golden Square, London, do 5 hereby declare the nature of the said Invention for “ Improvements in Regulating the Temperature op Vulcanizing Apparatus for Vulcanizing India-rubber used in the Manufacture of Artificial Teeth,” to be as follows:— My improvement consists in the structure and manner of combining 10 the gas or heat regulating apparatus to the vulcanizing chamber or boiler. The regulating apparatus is composed of a tube, through which the gas flows to the furnace or burner under the vulcanizing chamber or boiler. The quantity of gas admitted to the burner through this tube is 15 regulated by the expansion and contraction of mercury, which is placed in a suitable vessel in connection with the gas tube, and is exposed to the action of the heat of the steam in the vulcanizing chamber or boiler, and thereby keep the vulcanizer at any required temperature desired by
