Abstract
An emergency brake mechanism is provided, particularly for small railway cars such as those used for monorail systems, for braking a car released by failure of the motor and main braking system. The brake mechanism includes a brake shoe with tapered surfaces extending in opposite directions longitudinally of the path of movement of the car for wedging a brake pad between the shoe and the rail surface. The brake pad is pushed into engagement by a movable tappet, which in turn is released to move toward the rail surface by a centrifugal governor monitoring the speed of the car. The brake housing mounts the brake shoe on one side of the rail with a counter-brake surface on the opposite side.
