Description:
The curved gripping face for the handle, and the chain are both reversible. The bolt holding the jaw on to the bar, and the rivet connecting the chain to the pivoting link can be removed to enable those parts to be reversed, thereby doubling the useful life of the parts.

Application continued from original filed Nov. 30, 1915. (That application is noted in the specifications for patent no. 1,327,309.) This is the curved jaw component of the Williams FALCON chain wrench.
