W. R. Pidgeon
W. R. Pidgeon developed the pidgeon machine, an electrostatic machine with a unique setup.
Biography
Pidgeon presented his machine to the Physical Society after several years of investigation into influence machines. The device was later reported in the Philosophical Magazine and the Electrical Review. Pidgeon machines possess fixed inductors arranged in a manner that increases the electrical induction effect. The essential features of the Pidgeon machine are, one, the combination of the rotating support and the fixed support for inducing charge, and, two, the improved insulation of all parts of the machine. Pidgeon machines are a combination of a Wimshurst machine and Voss machine, with special features adapted to reduce the amount of charge leakage. Pidgeon machines excite themselves more readily than the best of these types of machines. In addition, Pidgeon investigated higher current "triplex" section machines with enclosed sectors.External articles
