Coes Wrench Company

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 October 1839 the facility where they worked was destroyed by a fire.

[3] 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.

[3] 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.

[3] 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.
