Toledo Wrench Company
Toledo Wrench Co. (Toledo, OH) - Incorporated August 30, 1883. In March, 1884 they are considering establishing a factory in Indianapolis. Here is a May, 1909 Machinery write-up on the Duquette chain pipe wrench.
We believe the early wrenches produced by this company were those patented by James Houlehan, but we have yet to discover a definitive link.
EDIT: We have found Mr. Houlehan in the 1885 Toledo City Directory employed as a General Agent for Toledo Wrench Company (See Image below). We can now say that their early wrenches were of Houlehan's patents.
