IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 9,298, dated October 5, 1852.

To all whom it may concern.-

Be it known that I, ROBERT M. JACKSON, of Penningtonville, in the county of Chester and State of Pennsylvania, have invented a new and useful Improvementin Corn-Planters;

posit the line earth upon the grain and throw the coarser parts to each side, and a markingrod by which corn may be planted to be in rows across as well as lengthwise.

To enable others to make and use my invention, I will proceed to describe its construction and operation.

I construct an ordinary frame, havingashovel-tooth, B, in thefront end ofa sufficient length and width to make a furrow. The front part otthe machine is carried by two wheels, 0, the

shaft of which drops corn once every revolution into the furrow from the box A on the top in the usual manner. I gear two cog-wheels, 1)

(I, together, (the larger fast on the axle which rev0lv'es,) which wheels give motion to the crank-arm E. I then have a riddle 0r sieve, F, for the purpose of sifting the pulverized earth upon the corn, with an uprlghtpieee, G, on the hinder end to keep the coarse parts from falling upon the grain and obstructingit in sprouting up. The sieve F is suspended, near the ground, to the frame by the rods H H, and over the furrow which the tooth B has made and in which the corn is dropped. The front end of said sieve being attached by the rod L to the crank-arm IE, it gives it a vibratory motion as it revolves. The plows m throw the earth upon the sieve, and its motion shakes the fine earth through it upon the corn, the stones and coarser parts passing off behind the plows to each side, the uprightpiece G preventing them from falling upon the row. 1 also have two miter-wheels, P l, geared together, connecting with the axle, making the rod S revolve as the machine is drawn forward, marking each place where corn is dropped, by observing which the grain in every subsequent row may be deposited directly opposite the places it was dropped in the first, and thus have it in rows across, so that it can be worked with the cultivator and plow both ways, as when planted with the hand-hoe.

What I claim as my invention, and desire to secure by Letters Patent, is-

The corn-planter sieve and its appendages, for the purpose of sifting and depositing the tine earth upon the grain and throwing oil stones and such matter as would obstruct the young sprout in coming through the ground, substantially as described and illustrated herein.

ROBT. M. JACKSON.
