Definitions

Fig. 8 is a cross sectional view of the circuit interrupting device shown in Figs. 6 and 7 with parts in circuit making position and showing adjacent parts of the shaft and slip ring partly in elevation and partly in section;
While my improved circuit interrupting device or governor may be associated with a motor to be driven of any desirable type to control its speed, or connected to a driven shaft to control the speed or operation of an associated or auxiliary device, in Figs. 1, 2 and 3 of the drawing it is shown connected in the load circuit of a motor Il to be driven which as shown is provided with an armature shaft I8 rotatably mounted in bearings I9 formed in a tubular extension of motor casing 2
a disk 22 formed of a suitable insulating material, such as molded or laminated material, is affixed to armature shaft I8 by any suitable means.
