Coes Wrench Co.

Worcester, MA - According to his obituary, Loring Coes invented his first wrench in 1828.  His first patent however is dated 1941. An advertisement in an 1899 edition of Hardware magazine claims Coes Wrench Co. was established in 1839.

The merger of the L. Coes & Co. and A. G. Coes & Co., forming the Coes Wrench Company, is announced in the 8/2/1888 edition of Iron Age.

At some point in the early 1900s, Coes was acquired by Bemis & Call.  On 2/28/1939 the acquisition of the wrench lines of Bemis & Call and Coes by Billings & Spencer is announced.  It was also reported that Bemis & Call would continue manufacturing locks resulting from their acquisition of the Sesamee Lock Co. of Hartford a few months prior.
