Abstract

495,443. Interrupters. WALLACE & TIERNAN PRODUCTS, Inc. May 11, 1937, No. 13407. Convention date, May 18, 1936. [Class 38 (v)] [Also in Group XXXV] The field windings of a motor are energized one at a time by a device controlled by rotation of the rotor. In the form shown, an interrupter comprising contacts 38, 39 is in series with each coil 20, 21 and the fraction of each revolution during which each coil is energized depends on the eccentricity of a sleeve 50 surrounding the motor shaft, the degree of eccentricity being controlled by a governor carried by the rotor. Each interrupter can be swung about its support 43, 51 to facilitate inspection. Specification 409,481 is referred to.
