CPC Definition - Subclass B61H
This place covers:
- Application or arrangements of brakes special adapted to rail vehicles
- Brakes with braking members acting on a track, e.g. scotch blocks, skids, track engaging shoes
- Actuating means for rail-vehicle brakes
- Transmitting means for actuating rail-vehicle brakes
- Wear compensating mechanisms for rail vehicle brakes, e.g. slack adjusters
This place does not cover:
Arrangements in rail vehicles for adjusting wheel-braking force to meet varying vehicular or permanent-way conditions | |
Transmitting braking action from initiating means to ultimate brake actuator with power assistance or drive, brake systems incorporating such transmitting means, e.g. air-pressure brake systems |
This place covers:
Braking member or members co-operating with the periphery of a wheel rim.
Braking member or members co-operating with the periphery of a drum, wherein the drum can provide a non-tread outside cylindrical surface that brake member(s) engage from the outside.
Braking member or members co-operating with the periphery of a drum arranged axially outside of the track width.
Braking member or members co-operating with the periphery of a drum or a plurality of drums arranged axially between the traction wheels.
Attention is drawn to the following places, which may be of interest for search:
Self-applying brakes | |
Combinations of different types of brakes | |
Wheels |
This place covers:
Brake members are moved outwardly against the inner surface of a drum or the like.
Brake members are moved outwardly against the inner surface of an inwardly directed friction surface on the wheel in the shape of a drum or the like.
Attention is drawn to the following places, which may be of interest for search:
Self-applying brakes | |
Combinations of different types of brakes |
This place covers:
Brake members are moved substantially axially against the surface of a brake disk or the like on the axle.
Brake members are moved substantially axially against one or more non tread surfaces of one or more traction wheels.

Discs adapted for mounting on the wheel of a railway vehicle |
This place covers:
Brakes applied to one or more tracks on which the train runs.
Brakes applied to at least one rail exclusively arranged for braking purposes.
This place does not cover:
Positive railway stops or track brakes secured to permanent way |
This place covers:
Brakes peculiarly adapted to vehicles running on rails.
Combination of brakes peculiarly adapted to vehicles running on rails and brakes not peculiarly adapted to vehicles running on rails.
This place covers:
Systems or arrangements for actuating rail vehicle brakes upon will of an operator.
Systems or arrangements for actuating rail vehicle brakes independently of the will of an operator e.g. in reaction to forces exerted to buffers or coupling gear.
Attention is drawn to the following places, which may be of interest for search:
Actuators directly acting on a brake head | |
Self-applying brakes | |
Wear-compensating mechanisms |
This place covers:
Devices to compensate for the wear of brake member(s) and/or friction surfaces.
Devices to compensate for the stretch of brake rigging.
