These new surroundings hastened the development of an existing idea: an adding machine. His new job gave him the opportunity to build his prototype. Accuracy was the foundation of his work. He made his design drawings on metal plates to prevent distortion. Burroughs filed his first patent for the invention of a "calculating machine" in 1885. It ...
