ABSTRACT:
An automatic brake for wheeled, carriages is characterized by U-shaped rod brackets, with integral out turned ears having brake rods slidable, and spring biased outwardly therein. The rods are preferably right angular so that identical brackets can be used for the telescopable finger grip actuating mechanism. In baby carriages the finger grip is spaced only for adult hands. In wheel chairs the brakes are released by the finger grip of the pusher or by a lever actuated by the leg of the occupant. In shopping carts the brakes are released by the finger grip of the pusher or by a lever actuated by the up-swing of the rearward nesting gate.
