A true roads icon turned 80 this year - that humble and ubiquitous plastic safety device, the Traffic Cone, is now an octogenarian. Over the years it has proven to be one of the most impactful yet ignored inventions ever to hide in plain sight. On 2 November 1943, Charles Scanlon a county line painter from California was granted a patent for his invention of a 'portable, deformable and stackable safety device', the TRAFFICONE. This was the start of the cone's worldwide takeover. Scanlon, indirectly an early pioneer of passive safety devices, identified that something better than the commonly deployed wooden and metal tripods was needed to keep traffic off freshly painted white lines. With the help of a local tyre firm, he devised a means of using old tyres to fashion a conical safety device, painted yellow with a red tip, which could be easily deployed on the highways and not damage vehicles when struck. The cones had small 'feet', which kept them off the painted lines, and a hole in the top to facilitate carrying and allow air to flow to help in separating them when stacked. |
