Supreme Court of the United States January 8, 1894, 156 (Keystone Manufacturing Co. v. Adams)

Mr. Justice Shiras,

after stating the case, delivered the opinion of the court.

Prior to the invention patented in 1812 by Henry A. Adams, a well-known defect in cornshellers consisted in the clogging or choking of the chute through which the ears of corn descended.to the sheller. As the ears would approach the throat of the machine, they were liable to stop and. wedge against each other.
