Traffic Cone

A traffic cone, also called a pylon, witches hat, road cone, or safety cone, is a cone shaped marker set out to redirect traffic temporarily, commonly around road construction or after a crash. Charles D. Scanlon, who worked for the Los Angeles Street Painting Department, grew frustrated with wooden tripods and barriers that broke easily and became hazards themselves, and designed a rubber cone that would spring back upright after a glancing blow, patenting it in 1943. The United Kingdom first used traffic cones in 1958 on the M6 motorway during construction of the Preston Bypass, replacing paraffin burners, and David Morgan is reported to have made the first experimental plastic cones in 1961 while at Imperial Chemical Industries; in the United States, Pacific Gas and Electric adopted orange safety cones for its service trucks on May 1, 1959, after a suggestion from employee Russell Storch. Modern cones are usually molded from brightly colored thermoplastic, sometimes recycled from PVC bottles, and carry retroreflective sleeves for night visibility and a boss at the top for carrying and for attaching caution tape.
