A Johnson Bar, aka "J"-bar, is a lever-dolly; (a wheeled prybar having an extended handle and a deep reverse-beveled nose-iron), which is used to jockey heavy apparatus into position.
In 1940, at Great Lakes Training Station, the janitorial staff used a "Johnson Bar". which consisted of a long bar with a weighted pad that was swung from side to side using the long bar to clean and wax hardwood floors.
