An improved machine for planting corn and other seeds, has been invented by R. C. Wrenn, of Mount Gilead, Ohio. The novelty of this invention consists in discharging the grain at regular intervals, and in hills at any desired distance apart, by means of one or more cams upon the face, and near the periphery of the driving wheel. These cams operate certain slides which convey the grain from the hopper to the hollow drill tooth. After the discharge of the grain into the drill is effected, the slides are instantaneously brought back to their natural position by means ot elbow shifters attached to the glides and operated by the cams. By this very simple arrangement) the necessity of employing shifting levers or other complex machinery, to be operated by hand, is dispensed with. Mr, Wrenn has taken measures to secure a patent.
