The Thompson-Houston System of Electric Lighting
"The Thompson-Houston System of Electric Lighting" by H. T. Cory is a scientific publication written in the late 19th century, specifically around the time when electricity began to gain significant public interest and practical application. This thesis, submitted for the degree of Bachelor of Science in Mechanical Engineering to Purdue University, provides a comprehensive overview of the Thomson-Houston System of producing electric light through electrical currents. It delves into the technological advancements in dynamos and electric lighting systems during that period. In the thesis, Cory outlines the principles and mechanics behind the Thomson-Houston dynamo, emphasizing its unique features and advantages compared to other electric systems of the time. The work discusses the dynamo's construction, including its spherical armature and field magnets, as well as the functionality of its commutator and regulating gear. Furthermore, it describes the evolution of electric lamps used in conjunction with this system, detailing both arc and incandescent lamps. With thorough explanations and historical context, the thesis serves as a guide to understanding how electric lighting was developed and implemented in various applications, illustrating its potential as a transformative energy source.
