Abstract
4227. Johannesen. S. E. March 3, 1906, [date applied for under Patents Act, 1901]. Transformers.-Auto-transformers are so arranged. that the voltage may be varied without disturbing the symmetry of conditions as regards leakage, the reactance being also maintained approximately constant. The transformer comprises two sets of coils, one set comprising coils 2, 3, 4, 5 in series with the terminal of a supply conductor, and another set of coils 8, 9, 10, 11, which are subdivided and joined together at the points of subdivision and are in parallel with the terminal of the other supply conductor 24. A movable switch arm 21 may be employed to connect one terminal of the motor &c. 22 to any of the contacts 16 ... 20, thereby regulating the voltage applied to the motor. In order to vary the voltage of the transformer, the terminal 25 of the set of coils 2, 3, 4, 5 is adapted to be connected to the terminals or points of subdivision of the coils 8, 9, 10, 11. The coils are symmetrically disposed with reference to each other, as shown, or they may all be placed in a line.
