Assembling and testing turbines, Westinghouse Co. works - From the Library of Congress
In 1904, Westinghouse Companies created a series of short silent movies depicting various enterprises.
In this short video, a turbine is shown operating. Two men walk up to it, check the running of various parts on it, and write their findings down on paper. A third man is seen walking through a few times, once stopping to look at one of the men's writings.
