Abstract
A fluid brake system has a brake pipe, a control valve device, a brake cylinder and a brake rigging, and in addition, a handbrake pipe, a protective device, a fluid pressure releasable spring handbrake cylinder, and a manually operable handbrake device for selectively governing brakes of the brake rigging under varying conditions, as when air supply is disconnected from a train. A moveable fulcrum in the manual handbrake device permits manual release of spring applied handbrakes in combination with a resetable toggle locking connection to a handbrake rod.
