Metal letters on the front rim: "The Liquid Carbonic Corporation, built by CE-Superheater, Inc." Patent No. 2,435,913 (see attached Multimedia links for patent documents). The patent was filed in November 1946 by Marion Pryor Wall of Lookout Mountain, and approved in February 1948.

History: "During the Great Depression, C-E formed a partnership with the Superheater Company. The Locomotive Superheater Company was founded in 1910 to further the use of superheated steam in locomotives. The Superheater Company's primary manufacturing facility was located in East Chicago, Indiana. In December 1948 stockholders approved a merger between the Combustion Engineering Company and Superheater Company. Following consolidation the corporation was called Combustion Engineering-Superheater Inc. In September 1950 the firm announced plans to build a large high-pressure generating unit for Virginia Electric & Power Company in Chester, Virginia. In 1953, the name Superheater was eliminated and the company took the more familiar name - Combustion Engineering, Inc. At this time, C-E primarily designed and built boiler assemblies for conventional power plants; those powered by coal and oil."
