Abstract

729,428. Controllers. SMIT & CO.'S TRANSFORMATORENFABRIEK N.V., W. July 24, 1951 [Aug. 1, 1950], No. 17498/51. Drawings to Specification. Class 38 (3). A cylindrical controller has spring-biased contacts on its rotor which co-operate with conductive rings or segments on the stator of the controller, and, in order to remove the rotor, partly cylindrical sleeves are placed within the controller and are turned so as to enclose the spring-biased contacts within the sleeves. The lower ends of the sleeves have flanges which are adapted to engage the inturned edge of a cupshaped member at the lower end of the rotary part of the controller. The same arrangement may be adapted for controllers having spring- biased contacts on their stators or on both their rotors and stators.
