The Coes Wrench Company was founded April 1, 1888.
Early Company history
Coes and his brother Aury Gates Coes worked for the firm of Kimball and Fuller, a firm that made machinery for the woolen industry. In 1836 the Coes brothers purchased the business and formed the L. & A. G. Coes company as a partnership. In October 1839 the facility where they worked was destroyed by a fire. The Coes brothers were unable to continue in businesses so they moved to Springfield, Massachusetts to work as pattern makers in the foundry of Laurin Trask.
Invention of the screw wrench
It was while they were living and working in Springfield that Loring Coes invented the screw wrench commonly known as the monkey wrench. Prior to the invention of the screw wrench, the two common wrenches of the time, the English patent wrench and the Merrisk wrench (also known as the Springfield wrench), needed two hands to adjust, whereas the new screw wrench could be used and adjusted with one hand.
The Coes brothers sold their pattern for spinning machines that they had rescued from the fire that destroyed their plant, and used the money to pay for the patent on the screw wrench that Loring Coes was granted on April 16, 1841.
L. & A. G. Coes
After they were granted the patent for the screw wrench, the brothers company L. & A. G. Coes went back into operation and they began to manufacture their new wrench.
In 1888 Coes Wrench Company was merged with the Loring Coes & Company.
