Early History
The Coes Wrench Company has a rich history that spans over a century. It all began in 1836 when Loring Coes and his brother Aury Gates purchased the wool machine business from Kimball & Fuller in Worcester, Massachusetts.
The brothers continued manufacturing these machines until a fire destroyed the plant in 1839. The Coes brothers then moved to Springfield, Massachusetts, to work as pattern makers at the foundry of Laurin Trask.

Loring Coes invented a new adjustable screw-type wrench, also known as the monkey wrench, while working for Trask. This innovative tool only required one hand to operate, a significant improvement over previous wrenches.
The Coes brothers established L. & A. G. Coes in 1841 to manufacture the wrench. They initially sold their tools to dealers and contracted with firms like Calvin Foster & Company and Ruggles, Nourse & Mason.
Here's a brief timeline of the company's early history:
In 1869, the Coes brothers separated and dissolved their partnership, with Loring taking the knife manufacturing portion and Aury Gates taking the wrench production.
Screw Invention
The screw wrench, also known as the monkey wrench, was invented by Loring Coes in Springfield.
It was a game-changer for tool users, as it could be adjusted with one hand, unlike the English patent wrench and the Merrick wrench, which required two hands.
The Coes brothers were quite entrepreneurial, as they sold their pattern for spinning machines to fund the patent for the screw wrench, which was granted on April 16, 1841.
This invention was a significant improvement over existing tools, and it's amazing to think about how it has impacted the way we work with tools today.
The screw wrench has become an essential tool in many industries, and its impact is still felt today.
