Abstract: A steerable three-wheeled cart has a frame supported by a pair on non-steerable rear wheels and a steerable front wheel. The front wheel is mounted on a steerable wheel carriage that is journaled to the frame for rotation of the carriage and wheel about a generally vertical axis. A handle is pivoted to the wheel carriage to effect steering of the front wheel. The handle mounts a braking member whose braking surface is curved both longitudinally and laterally so as to conform substantially to the curvature of the front wheel. A braking force is applied to the front wheel by rocking the handle downwardly to cause the braking member to bear against the wheel while retaining the ability to steer the wheel with the handle.
