Today in 1916, US Patent 1170839 A was issued, an invention of John J. Molloy, for his “Barley or Rice Huller.” There’s no Abstract, although in the description it includes this summary:
This invention relates to grain hullers and particularly to barley and rice pearlers. It is an object of this invention to provide a simple, practical, automatic-feed continuously operating hulling machine of high efficiency in capacity and cleanness of product particularly designed for handling rice. A further object is to provide a huller in which the quantity of the discharge may be readily and accurately controlled and whereby the degree of pressure of the grain in transit is regulated and maintained uniform.
