82. WOODS, JAMES, Stowmarket, Suffolk — Inventor and Manufacturer.
Registered iron-crushing and grinding mill, for linseed, oats, barley, Indian corn, rice, lentils, malt, etc. It crushes and grinds separately, or does both at the same time, as two distinct hoppers are provided, and no alteration of machinery is required. The crushing is performed on the surface of a large wheel, 4 feet diameter, in conjunction with a small roller, 7 inches diameter. A steel roller is attached to the axis of the large wheel for grinding beans and peas, so that friction from increased bearings is avoided. The figure shows the form of this mill.
