Description: |
| Inventor Charles D. Scanlon was reportedly a street painter when he invented the pyramidal resilient traffic cone with weighted base. "At present is is customary to use small wooden tripods or larger wooden barriers to indicate the presence of dangerous spots in the highway such as those caused by repairs... a major object of my invention is to provide a market which is readily visible, yet which causes no damage to an automobile if the latter strikes it. It is another object of my invention to provide such a marker which will return to its upright position after a glancing blow, and which may be dropped from a moving truck and assume an upright position. It is a further object to provide a marker of this type which may be stacked so as to require a minimum of storage space, and to be easily transported..." In this patent, the cone was made of "fabric of old automobile tires from which most of the rubber has been removed". The base was formed from multiple thicker pieces of old tires. By 1947 these cones were being manufactured. In 1961 British engineer David Morgan introduced the idea of molded plastic traffic cones. |
