Abstract
Abstract A bumper extension construction is disclosed comprising plate hangers adapted to be detachably secured to the opposite sides of the frame of an automobile and to depend therefrom. Spaced Ushaped brackets have their legs welded to said plate hangers to provide spaced, longitudinally extending passageways. In each passageway a bumper arm is slidably mounted for extension or retraction. Spring-loaded, wedge-shaped catch means are provided so a selected extension can be maintained without the use of bolts or tools, thus eliminating any looseness of parts during travel in forward and reverse directions. Also, spring-loaded wedges are provided to eliminate mechanical rattles between the bumper arms and the frame means forming the longitudinal passageways for the reception of said bumper arms.
