“Kingsbury tried to file for a U.S. patent during 1907. His initial application was rejected as a British patent had been granted in 1905 to A.G.M. Michell who had a similar concept. Kingsbury was able to demonstrate that his 1898 test at the University of New Hampshire predated Michell’s work, so in 1910 Kingsbury was awarded US patent No. 947242 for the tilting pad thrust bearing.”

“Kingsbury continued to pursue his interest in bearings and tribology later in his life. One of his greatest achievements was his analysis of the effects of side leakage of lubricants from bearings. By recognizing the analogy in the equations for lubrication and those for electrical flow in a conductive fluid and variable depth, Kingsbury was able to make complicated predictions of slider load capacity well before the advent of computers.”
