A.P. Joy patent adjustable wrench

Description

This adjustable wrench was patented by A.P. Joy of Newmarket, NH  on 1 February 1898.  It has a somewhat novel adjustment mechanism.  They are not especially common.

This thing is a brute – 14″ long and heavy as hell.  Looks like it’d take a square nut up to about 3 or 4 inches in size, so was probably meant for wagons and the like.  I’ve not seen an example this big online or elsewhere.

This one needs a good de-rusting, but is otherwise in good shape.
