Automatic Flour Mill
Evans first invention of widespread importance was an automated flour mill which operated continuously through the use of bulk material handling devices including bucket elevators, conveyor belts, and Archimedean screws. Evans described this invention in The Young Mill-wright and Millers' Guide. He patented this invention in a few states and, when the US patent system was established, in the federal patent system (Third U.S. Patent).
Evans' description of his fully automatic flour mill:
" These five machines…perform every necessary movement of the grain, and meal, from one part of the mill to another, and from one machine to another, through all the various operations, from the time the grain is emptied from the wagoner's bag….until completely manufactured into flour…without the aid of manual labor, excepting to set the different machines in motion."
The automatic flour mill was built ca. 1785 in Newcastle County, Delaware.
The Evans material handling system became widely used in flour mills and breweries during the 19th century.
David Hounshell (1984) acknowledged the influence of Evans'es automatic flour mill in the sequence of innovations leading up to the assembly line.

Famous quotes containing the words automatic, flour and/or mill:
“The ruin of the human heart is self-interest, which the American merchant calls self-service. We have become a self- service populace, and all our specious comforts—the automatic elevator, the escalator, the cafeteria—are depriving us of volition and moral and physical energy.”
—Edward Dahlberg (1900–1977)
“I wol bistowe the flour of al myn age
In th’actes and in fruit of mariage.”
—Geoffrey Chaucer (1340?–1400)
“—First a shiver, and then a thrill,
Then something decidedly like a spill,—
And the parson was sitting up on a rock,
At half-past nine by the meet’n’-house clock,—
Just the hour of the Earthquake shock!
MWhat do you think the parson found,
When he got up and stared around?
The poor old chaise in a heap or mound,
As if it had been to the mill and ground!”
—Oliver Wendell Holmes, Sr. (1809–1894)
