Patent Number Date Title Name City Description
381,968 May. 01, 1888 Electro-magnetic motor Nikola Tesla New York, NY This and patents 381,969 and 381,970 are the first patents for the AC induction motor. The patent was assigned to himself and Charles Peck, but they sold the patent to Westinghouse in July of 1888. Tesla moved to Pittsburgh for a year to train Westinghouse personnel.
404,567 Jun. 04, 1889 System of generators for alternating electric currents Oliver B. Shallenberger Rochester, PA This patent relates to two-phase distribution systems which Westinghouse was researching at the time. Inventor Shallenberger had developed a power usage meter device that was considered by George Westinghouse to be a key component of their electrical distribution system offering; it worked at 133 Hertz which would prove to be an obstacle to the development of a viable polyphase alternate-current distribution system.

610,067 Aug. 30, 1898 Induction-motor Benjamin G. Lamme Pittsburgh, PA Benjamin Garver Lamme was an important electrical engineer for Westinghouse. After Westinghouse's researchers failed to industrialize Tesla's two-phase motor (for a 133 Hertz supply), it was abandoned until Lamme focused his attention on it in late 1891, leading to the development of a practical 60 Hertz version of the Tesla motor. This was the first fully practical induction motor from Westinghouse. Another Westinghouse researcher, N. W. Storer, would modify Lamme's motor to a squirrel-cage design, which would prove to work as well and was simpler to manufacture. The Westinghouse two-phase motor was demonstrated at the 1893 Chicago World's Fair.

4,718,172 Jan. 12, 1988 Turbine Blade Radial Position Gage Marshall J. Rouse Charlotte, NC Abstract
A gage for determining alignment of a turbine rotor blade in an assembly position on a turbine rotor. The gage includes a precision base for positioning on the rotor surface adjacent a blade to establish a tangent line perpendicular to a rotor radial line through the center of a slot in which a blade is disposed. A standard extends from the base and carries a first contact for positioning against a low portion of the blade and a second measuring contact for positioning against an upper portion of the blade. The measuring contact provides an indication of blade misalignment.
