锘? Albert Kingsbury was born in Morris Matt Flynn Patriots Jersey , IL and graduated from Cuyahoga Falls High School, OH in 1880. Albert Kingsbury would eventually father five daughters. In addition to his interest in tribology and bearings, Albert Kingsbury enjoyed the world of arts, history and letter. He also devoted much time to the study of foreign languages. Albert Kingsbury died in 1943, and was buried at the Quaker Cemetery, Spring Mills Dekoda Watson Patriots Jersey , PA. In 1884, Albert Kingsbury attended the University of Akron to study Scientific-Latin courses. He dropped out of the school and worked as a machine apprentice in Cuyahoga Falls. Kingsbury credited this as an important experience that led him to advance his career in engineering. Kingsbury resumed his formal education at Ohio State University, but he again dropped out to work as a machinist with the Warner and Swasey Company in Cleveland. Albert Kingsbury eventually received his mechanical engineering degree from Cornell University in 1887. More importantly, it was at Cornell that he met Professor Robert H. Thurston. Professor Thurston was instrumental in shaping Albert Kingsbury interest in bearings and tribology. Working under Professor Thurston, Albert Kingsbury conducted tests on bearing materials for the Pennsylvania Railroad. His craftsmanship, honed by his experience in machine shops allowed Kingsbury to fit half-bushings to the journal by scraping. His hand fitting produced the small tolerances that promoted film lubrication. These bearings Malcolm Butler Patriots Jersey , when ran showed no measurable signs of wear, and was Kingsbury prompt to the creation of the thrust bearings which now bear his name. University of New Hampshire Upon graduation, Albert Kingsbury chose to pursue a teaching position at the University of New Hampshire. Within two years, he was a professor of Mechanical Engineering courses at the university. His new position at the university allowed him to continue pursuing his interest in lubrication. During his time at the University of New Hampshire, he created an innovative test machine to measure friction in coarse pitch, lubricated screw threads at loads of up to 14 Alan Branch Patriots Jersey ,000 psi. The usefulness of this invention received mixed reviews from the American Society of Mechanical Engineers (ASME). His research also covered fluid lubricated bearings, and he published an impressive paper entitled "Experiments with an Air Lubricated Bearing". It was at this university that he envisioned the Kingsbury thrust bearing. Albert Kingsbury joined the Worcester Polytechnic Institute to continue pursuing his interest in lubrication. He was also able to secure expansions for laboratory facilities and funding to continue his tests on a centrally pivoted thrust bearing with the aid of his students. Invention of the Kingsbury thrust bearing Albert Kingsbury research at the University of New Hampshire lead him to conceive an early Kingsbury bearing that consisted of several stationary arc segments facing a thrust collar on the rotating shaft. Each segment would have a boss on the side away from the thrust collar, allowing it to tilt and form an oil wedge that would carry the thrust. Kingsbury tested this new bearing with a modified version of his earlier screw thread testing machine. The bearing was successful with pressures of up to 4,000 psi at speeds of 285 rpm. This pressure exceeded that for common collar-type bearings by a factor of 80 to 100, thus proving the promise of the Kingsbury bearing. After his teaching career, Albert Kingsbury joined the Westinghouse Electric Company in Pittsburgh as a general engineer. He used this as an opportunity to advance the development of his thrust bearings in an industrial setting. Unfortunately Jabaal Sheard Patriots Jersey , the first test of his thrust bearing was a failure. His bearing overheated during the test and was discarded. This made the company skeptical of Kingsbury invention, but Westinghouse skepticism did not dent Kingsbury mettle. Kingsbury would later fund his own test that proved his bearings successful. Unfortunately Westinghouse decided to stick to more conventional ball bearings for their motors. Patenting of the Kingsbury thrust bearing Albert Kingsbury tried to file for a patent during 1907. His initial application was rejected as a British patent had been granted 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 work, so in 1910 Kingsbury was awarded US patent No. 947242 for the tilting pad thrust bearing. Success of the Kingsbury bearing Kingsbury would eventually run his own business with the Westinghouse Machine Co. building his bearings. This allowed him to actively pursue applications for his newly patented thrust bearing. His first chance came when the Pennsylvania Water and Power Co. gave him the opportunity to demonstrate his bearing on their power generator at the Susquehanna River. His first bearing was a failure as it was immediately destroyed by Babbitt wiping. Fortunately for Kingsbury, the Pennsylvania Water and Power Co. gave him a second chance. His bearing succeeded this time, and worked flawlessly for the next 25 years. When it was inspected after 25 years, there was so little evidence of wear that it was calculated that the bearing would last 1 Brandon Gibson Patriots Jersey ,300 to 1,700 years. In fact, the same bearing is still operating smoothly today! By World War I, the Kingsbury thrust bearing was used extensively in the navy especially to transmit thrust from propeller shafts to ships' hulls (i.e., the propeller pushes water in one direction, and the Kingsbury thrust bearing Antonio Johnson Jersey , attached to the shaft and mounted to the ship, pushes the ship in the opposite direction). In 1921, the Kingsbury thrust bearing had become so popular that Westinghouse could no longer keep up with the demand, thus prompting Kingsbury to set up his own manufacturing plant. Albert Kingsbury continued to pursue his interest in bearings .
