25. WINDSOR, JOHN, Oswestry — Manufacturer and Improver.
Winnowing machine, for wheat, barley, oats, beans, peas, etc. The improvements claimed are the peculiar construction of the riddle-case, and the placing of a flywheel on the fan spindle to regulate the speed, and produce an under-current of wind at the bottom of the cylinder to blow off any light substances.
Clover seed drill, for sowing all grass seeds and turnips on the flat. The bottom of the box is formed so as to cause the seed to fall to the brush until empty, and there is a movement for throwing the connecting spindle out of gear.
