Until Loring Coes came along, the monkey wrench was just a plumber’s pipe dream.

Before the Worcester man’s invention there were two types of wrenches - the English type and the Merrick, or Springfield wrench.

You couldn’t manipulate either with one hand to save your neck.

A patent granted to Coes in 1841 called for a screw so that the wrench could be held and adjusted with one hand.

Coes was born in Worcester in 1812; spent 14 years on his father’s farm; was apprenticed as a carpenter to Anson Braman.

When he was 22, he formed a partnership with his brother, Aury G. Coes, born in 1817, to make woolen mill machinery near Lincoln square. A fire three years later left them penniless.

The brothers went to Springfield, where they became pattern makers in a foundry. They saved their nickels; dreamed up the better “mouse trap.” They came back in 1840 to set up with borrowed capital as L. & A. G. Coes, wrench manufacturers. By 1843 they were employing three hands. Things were looking up.

Early in 1844, they moved to New Worcester. Two years later they owned the property; soon bought an old woolen mill, which they converted, water power rights and land. In 1853 they bought a knife manufacturing plant. On May 2, 1864, the Coes brothers dissolved partnership. Aury took the wrench plant at Webster square. Loring took the knife shop on Mill street. A few years later Loring built a new factory at Coes square to make wrenches.

In 1888, the Coes organized a joint stock company as Coes Wrench Co. with a capital stock of $100,000. Loring was president. As late as 1899 the concern was the only screw-wrench manufacturer in Massachusetts; hammered out about 40,000 wrenches a month.


Aury died at 58 in 1875. Loring lived to be 94; set some sort of record as the oldest fisherman visiting Maine. Number of trips: 47. He died July 13, 1906, “leaving a name that will be remembered so long as a wrench is used by mechanics the world over,” promised the Worcester Magazine.

Coes street-park avenue northwest to Mill street-was named by the brothers, who laid it out through their property. It first appears in 1871. Coes square and Coes Pond also honor their memory.
