445,207 - Electro-Magnetic MotorCategory: Motors & Generators Country: United States Application Date: May 20th, 1889 Issue Date: January 27th, 1891 
Among the various forms of alternating-current motors invented by me is one which I have described in other applications, and which is constructed as follows: I build a field-core with, say, four poles, between which is mounted an armature that is generally wound with closed coils. On two of the opposite poles of the... more >>

413,353 - Method of Obtaining Direct from Alternating CurrentsCategory: Power Distribution Country: United States Application Date: June 12th, 1889 Issue Date: October 22nd, 1889
In nearly all the more important industrial applications of electricity the current is produced by dynamo-electric machines driven by power, in the coils of which the currents developed are primarily in reverse directions or alternating; but as very many electrical devices and systems require direct currents, it has... more >>

433,700 - Alternating-Current Electro-Magnetic MotorCategory: Motors & Generators Country: United States Application Date: March 26th, 1890 Issue Date: August 5th, 1890
This invention is an improvement in that class of electro-magnetic motors in which the rotation is produced by the progressive movement or effect of the maximum magnetic points or poles produced by the conjoint action or effect of two energizing-circuits through which are passed alternating currents, or currents of... more >>

433,701 - Alternating-Current MotorCategory: Motors & Generators Country: United States Application Date: March 26th, 1890 Issue Date: August 5th, 1890
This invention relates to that class of alternating-current motors in which the field-magnets are energized by coils connected up in two circuits derived from the same source and having different degrees of self-induction, whereby the currents in one circuit or branch are retarded more than in the other, with the... more >>

447,920 - Method of Operating Arc-LampsCategory: Lighting Country: United States Application Date: October 1st, 1890 Issue Date: March 10th, 1891
This invention consists in an improved method of operating electric-arc lamps which are supplied with alternating or pulsating currents. It has now become a common practice to run arc lamps by alternating or pulsating as distinguished from continuous currents; but an objection to such systems exists in the fact that... more >>

447,921 - Alternating Electric Current GeneratorCategory: Motors & Generators Country: United States Application Date: November 15th, 1890 Issue Date: March 10th, 1891
In the systems of distribution of electrical energy from alternating-current generators in present use the generators give ordinarily from one to three hundred alternations of current per second. I have recognized and demonstrated in practice that it is of great advantage, on many accounts, to employ in such systems... more >>

455,067 - Electro-Magnetic MotorCategory: Motors & Generators Country: United States Application Date: January 27th, 1891 Issue Date: June 30th, 1891
The subject of my present invention is an improvement primarily designed for application to alternating-current motors of the special type invented by me, and of which the operation is due to the action of alternating currents differing in phase and directed through or developed in independent energizing-circuits in... more >>
