IMPROVEMENTIN HAND CORN-PLANTERS.

TO'ALL WHOM IT MAY CONCERN: i

l 4:Be it known that I, JAMES S. LAWSON, of Disco, in the county of Macomb,'and in theV State of Michigan, have invented an Improved Hand Corn-Planter; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in the following order, in which-v A Figure 1 is a perspective view. Figure 2, a-longitudinal view. l Figure 3, a sectional view through C D. Figure 4, a view of the sliding .valves a and b. Figure 5, a view showing the concentric rings or tubes ff, &c., by which the chamber m is enlarged or diminished, -to regulate the quantity of seed. i

4Figure is a view of the tube P, divided or flattened in such a manner as to separate the kernels in the hill. A ,g 1, is a tube, of metal or 4other suitable material, and of the required length and size. F' is a-portion ofthis tube, containing the chamber m, as shown in iig. 3, and firmly fastened to A by screws or otherwise. P is another portion of this tube, of required length, Ste., enlarged-and attened,.or divided at its lower end, and firmly attachedto F at its upper end. B is a blade of steel, of desired form and dimensions, and rmly fastened fto the lower end of P. a and b are slides or valves, made of thin strips of steel or 'other suitable material, and working through the'slots e c in the portion F. d d, g.4, are holes through the ends ofthe slides a I1, through which the end of thelever E passes, somewhat loosely, in order to secure a free movement of the slides through the slots c c. o and Lare openings through the slides aand'b, so arranged as to open and close alternately above and below the chamber m,'in the throttle fn, by a simple movement of the lever E.- k is a band clasped around the tube A, .and f ormingthe fulcrum ofv the lever E. His a spring `between the lever andthe tuhe A, and above the fnlcrum c. E is a lever, ofY light and strong material, for the purpose of operating the slides a and b, one e'nd of which, passesthrough the holes d in these slides, and the other, reachingnearly t`o' thetop of the tube A, is bent outward, to forni a rest for the hand ofthe operator. L is a cap fitting .closely upon' the top ofthe tube A,'to secure the grain, The chamber m is enlarged or contracted to suit the kind and quantity of seed, by inserting or withdrawing thin tubes tting one within -another, as shown atff in lig."5'. The openings t and o, in the slides a and b, 'are placed diagonally to each other in reference tothe chamber m, and so arranged that when the lever E is in the position shown in fig.v 1, Ywhere it is' always keptby the spring H, whenuot pressed by the hand in 'using the planter, the opening 7i in the slide b is directly over the o hamhervm, and the chamber is lled with the seedgrain. Now, byrdeprcssing the lever bythe hand at G,`the upper valve is clsed, and the opening o in the slide a is lbrought directly beneath the chamber m, and the seed escapes through the portion of the tube P, and is deposited in the ground beneath the blade B. The construction of the openings in thes-lides is such that a,'in a, is brought beneath m before h in b is entirely closed. This arrangement allows the seed to pass out of the chamber m before theslide bcomes in contact with the kernels belowin Athe chamber, thereby preventing the grain from clogging in the throttle, and securing a nearly uniform quantityl at each deposit. The lower portion ofthe tube P is divided or flattened in such a'manner as tofseparute the kernels somewhat in the hill, as may be seen in fig. 6. l

My planter is operated by placing thehandupon the leverat G and'around the tube A, in such a manner that two or more fingers can clasp the lever, the planter being held in an upright position in advance ofthe operator. B is then thrust into the ground to a suicientdeptli, and the top of` the planter `canried forward suicientlyto leave an opening in the ground beneath this blade. The end of the lever E is then brought down to the tube- A, at-G, und the grain falls into the ground beneath the blade B, which is then withdrawn, and the operator places his foot upon .the place ashe advances to the next hill, at the same time relaxing his hold upon the lever4 at G, and so on continually. I

When two 'planters' are used by the same person at one time, a barrow or rollershould be' passed over the field after planting, to better secure the covering of the grain, as-in such case the foot could not be placed upon both hills without considerable delay. i

New, what I claim as my invention, and desire to secure by Letters Patent, is- A vcombination of all the principal parts above described, essentially and for the purposes set forth, constitoting an entire machine.

In testimony that I claim the foregoing hand corn-planter, I have hereunto set my haiid, this 7th `day of September, 1867..

JAMES S; LAWSON.
