DEFINITION

Classification: 246/483

(under subclass 482) Subject matter having semaphores in which the novelty resides in means for illuminating the arm

or blade by either natural or artificial light not emanating from the train.

(1) Note. Pivoted-arm signals, not strictly semaphores within the definition of subclass 479, are here included, provided they disclose means for illuminating the arm-or blade. Signal-arms or targets illuminated by light from the train will be found in subclass 474.
