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.
417,794	Dec. 24, 1889	Armature for electric machines	Albert Schmid	Allegheny, PA
		Armature for electric machines	Nikola Tesla	Pittsburgh, PA
450,641	Apr. 21, 1891	Self-exciting alternate-current electric generator	William Stanley Jr.	Great Barrington, MA
556,646	Mar. 17, 1896	Device for detecting short circuits	Charles E. Skinner	Allegheny, PA	This patent seems to be the genesis of the "growler", a device used to test motor windings and other electrical coils for shorted windings.
		Device for detecting short circuits	Charles F. Scott	Pittsburgh, PA
583,584	Jun. 01, 1897	Gas Engine	George Westinghouse	Pittsburg, Allegheny County, PA	Application renewed 29 Apr, 1897.

606,056	Jun. 21, 1898	Alternating-current electric motor	Robert H. Hassler	Pittsburgh, PA
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.
