Rees Sheneman lavished much-needed attention on the Mill and its property, care that had been sorely lacking since the Lightfoot era.

In the early 1820s he installed revolutionary technology created in the 1790s by a Delaware inventor named Oliver Evans, which allowed for continuous production in gristmills. The labor-saving elevators and conveyors eliminated the need to carry grain between the different floors in the Mill.

Sheneman incorporated these new devices into the existing power train system, leaving the original Lightfoot technology untouched.
