Erector Set is the trade name of a metallic toy construction set originally patented and manufactured by the AC Gilbert Company of New Haven, CT. that is popular in the United States. It consists of collections of small metal beams with regular holes for nuts, bolts, screws, and mechanical parts such as pulleys, gears, and small electric motors. The brand name is currently used for Meccano sets sold in the United States. Patented in 1913, The Erector Set was invented by AC Gilbert in 1911, and was manufactured by the A. C. Gilbert Company at the Erector Square factory in New Haven, Connecticut, from 1913 until its bankruptcy in 1967. The Gabriel company of Lancaster, Pennsylvania bought the Erector name, and continued to make identical sets into the 1970s and 1980s. The Erector Set is believed by many to have been the subject of the first national advertising campaign in America for a toy.
