Description: |
| "In dynamo electric machines of large size the coils forming the winding of the field necessarily project some distance form the core and, owing to their great weight and the softness of the metal of which they are composed, some means must be provided to support them or they will sag and come in contact with the revolving part of the machines. Heretofore, as far as I am aware, such coils have always been supported by a rigid support being held against said support either by a second rigid support or by a winding of rope or cord. In either case, however, the resultant support has been rigid so that all the vibrations of the machine, or practically all the vibrations, are transmitted to the winding. The object of my invention is to provide a flexible support for the ends of the coils so as to reduce the amount of vibration transmitted to them to a minimum." |
