The movable jaw contains a pipe-gripping jaw which is not attached to the frame by any solid connection or spring. The remainder of the wrench closely resembles the "Donohue's Patent" nut and pipe wrench (pat. nos. 195,589, 238,369, and 268,784) -- marketed by Tower and Lyon. John J. Tower and Polhemus Lyon formed the firm in 1884.
