Description:
A vertical screw and nut with projecting arms provides "depth" adjustment; the patent also describes the two-part frame for the screw.

A March 1887 ad for "front adjusting" model of the UNIVERSAL Plow (Canton, OH) and a 1901 ad image for the UNIVERSAL Plow produced by A.T. Stewart Co., Pittsburgh, PA & successor to Princess Plow Co., Canton, OH, appear to show a similar clevis structure.
