Means for transmitting electrical energy between relatively moving objects. Generally involves the problem of transmitting electrical energy from fixed points to vehicles or other moving objects, or vice versa.
(1) Note. Includes the combination of generation and transmission to and from the vehicle, but does not include specific means for applying the electrical energy to any specific purpose, which are classified according to the application.
LINES WITH OTHER CLASSES
This class does not include mere slip rings and brushes, which are classified in Class 310, Electrical Generator or Motor Structure, subclass 232; rail bonds which are classified in Class 238, Railways: Surface Track, subclasses 14.1+; nor means peculiarly adapted for transmitting electrical energy momentarily to a vehicle for the purpose of operating a signal, switch, etc., which are classifiable in Class 246, Railway Switches and Signals, and will be found in the various subclasses containing the words "Intermittent contact" in the title.
