Electrically nonconductive rotary cleaner elements supported for movement into and out of contact with a third rail of an electrified railway vehicle includes sets of cleaner elements arranged in tandem along one side of an adjustable carriage. The carriage is mounted in a frame structure having a device for rigidly attaching the frame to a wheel truck portion of the railway vehicle. Power driving apparatus received in the carriage provide for vertical movements of the carriage in the frame as well as actuating the rotary cleaner elements. The drive apparatus is responsive to a control device located in the cab of the railway vehicle. A counterbalancing weight arrangement mounted in the frame and attached to upper sides of the carriage provides for uniformly guided travel of the carriage in all positions.
Cleaning apparatus for removing ice and sleet from a third rail of an electrified railway vehicle, said apparatus comprising a frame, means for rigidly securing the frame to a wheel truck portion of the vehicle, a vertically adjustable carriage slideably disposed in the frame, rotatable cleaner means arranged at one side of the carriage, means for vertically adjusting the carriage in the frame and moving the rotatable cleaner means into and out of contact with the said third rail of the railway vehicle, and means for actuating the rotatable cleaner means when moved into engagement with the third rail.
