Vehicle-Brake.
Patent for an improvement in automatic vehicle-brakes by using sliding rods that are movable within staples or guides and a brake-bar indirectly attached to the rear axle by means of a coiled spring. When the brake bar moves forward, it forces the break-shoes from contacting the wheels. When the brake bar moves backward, it forces the brake-shoes into contact with the wheels, thus stopping the vehicle. Illustration is included.
