From 1869-02-06 Scientific American

Starting about 1863, this firm was one of the early makers of reciprocating ship's saws (though considerably preceeded by New York maker James Hamilton). Their machine was a direct predecessor to the Fay & Egan bandsaw-based ship saw. By 1865, Knowlton was on his own and operating as John L. Knowlton. He continued making ship saws, steam engines, and fire engines until his death in 1876 or shortly before.
