Why Monkey Wrenches?

The Monkey Wrench was invented by Loring Coes & Coes Wrench Company of Worcester, MA in 1840. During the industrial era of the 1860s-1910s, various monkey wrench types were the dominant form of adjustable wrench. A very wide and popular range of monkey wrenches were manufactured by Coes family partnerships, licensees and companies, which filed further wrench patents throughout the 19th century. In 1909, the Coes Wrench Company advertised a six-foot-long "key" wrench, shaped like a monkey wrench, for use on railroads, relating back to the Railers. Worcester Monkey Wrenches Weekend is a weekend to celebrate innovation and the city of Worcester!
