The W estern R iver S teamboat H eroine , 1832–1838, O klahoma, USA : propulsion machinery

Abstract

This paper completes the description of the western river steamboat Heroine (1832–1838) (Crisman et al. 2013b; Crisman, 2014), with a detailed analysis of the steam propulsion machinery recovered. Heroine's place in the development of steam technology is analysed through historic sources and comparable finds, and the requirements of river navigation explored. Changes to the paddle flange and the short‐lived use of flywheels are particularly noted. The many variations in the iron castings and evidence of makeshift repairs provide insight into the material, engineering and economic constraints faced by engine manufacturers and steamboat engineers in the second quarter of the 19th century.
