UNITED STATES PATENT OFFICEQ JAMES W. CLARK, OF KIRKERSVILLE, OHIO, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO JOHN ALGEO, OF SAME PLACE.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 227,488, dated May 11, 1880.

Application filed February 20, 1880.

To all whom it may concern:

Be it known that 1, JAMES WILLsQN CLARK, of Kirkersville, in the county of Licking and State of Ohio, have invented certain Improvements in Corn-Planters, of which the following is a specification.

My invention relates to improvements in corn-planters of the runner or shoe class, in which the covering of the seed in the furrow is done by means following immediately after the hopper; and the object of my said improvements is to simplify the construction of cornplanters of this class and to permit the furrow cutter or opener and dropper to work within an opening in the shoe. I also design to throw the opener out of its operating position, so that the corn-planter may be moved from the field without bringing into play the cutting parts.

The invention and the preferred construction by which I attain my said. objects are hereinafter fully set forth in the following description, illustrated by the drawings, and specified in the claims.

In the said accompanying drawings, Figure 1 represents a view, in perspective, of a planter embracing my improvements; Fig. 2, a vertical section taken through one of the hinged hoppers, its opener, and the shoe, the parts be- 0 ing in the positions they occupy when in use;

Fig. 3, a similar section, the parts being in the position they occupy when the hinged open-. ers and their connected hoppers are raised out of use, and Fig. 4 a rear view of one of the 3 5 shoes and its connected parts.

To the front bar of the frame A the toe of each shoe B of two end shoes is attached, the heel portion being secured by rods G G to the rear bar of said frame. There is a hopper,

D, for the seed at each side of the frame, each hopper being held by a connection with the cutter at openerE, and with the carrying-frame F, as will be hereinafter described. Each shoe B has a slot, at, running from near its toe fully through the heel, as shown. The openers E operate within these slots, and each opener is hinged to the inner side of the shoe in lugs b at a point above the commencement of the slot to, within which it works, while the end of the cutter is held by a rigid connection with the bottom of the hopper.

In order to correspond with the shoe when lifted andpresent a dragging-surface flush with the tread of the shoe, the opener E is tapering in form from its heel to its hinge-arm c 5 5 to and throughout the cutting part, and the heel of said cutter or opener has an edge groove or half-tube, d, coincident with the hopper-exit 0, through which the corn drops into the furrow and is covered. This opener E is also broader on its cutting-surface at the heel e, where it is fastened to the hopper, than at any other point, in order to make a furrow wide enough for the corn or seed. That portion of the shoe B back of the dropping-point or opener-heel 0, has the outer edges of the two sides ff, formed by the slot a, turned downward in a gradual taper from said droppingpoint to a decidedly downward turn at the extreme end, in order to cover the corn dropped in the furrow by pressing or handling the dirt together over said furrow.

As before described, the heel of the opener E is attached directly and rigidly to the hopper D, and while the operation of planting is going on the openers are held down to their work, in position below the slots in the shoes,

by means of a lock-bar, Gr, pivoted to the front bar of the frame A, so as to have a horizontal movement, and passing through a loop-strap, g, on the cross-bar of the hopper-carrying frame F, and under a lock, h, Figs. 1 and 2, on the frame A, under the seat H, for the-operator; and when it is desired to leave the field the lock-bar is raised by the operator over the said 8 5 lock h, Fig. 3, thus lifting the hoppers and the openers to a height sufficient to bringtheopeners in the slots at above or on a level with the tread-surface of the shoes.

Hinged to the carrying-frame F, and oper- 9o ated by a lever, I, fulcrumed in the frame A in front of the operators seat, (the rod is making the connection,) is the arm-carrying board K, which carries the arms L, which operate the seed-slides M, the connection with the slides 5 being by holes at therein, through which the .ends of arms L work as the lever is moved.

The seed-slides have two valves or openings,

a" T, which are for the purpose of acting in connection with the seed and fertilizing divisions of the hopper, so as to drop the fertilizer immediately after the dropping of the seed.

' I claim- 1. The combination, in a corn-planter, of the curved slotted shoe rigidly attached to the main frame with the curved opener hinged to said shoe and adapted to be raised and lowered within the slot thereof to project it below the bearing-surface of said slotted shoe, and to be raised to bring its cutting-edge above or coincident with such bearing-surface when not in operation.

2. In a corn-planter, the combination of the curved slotted shoe rigidly attached to the main frame and the curved opener hinged to said shoe for operation within the slot thereof, substantially as herein set forth, with the hoppers, their dropping-slides, and the operating mechanism therefor, said openers forming a continuation ofthe seed-conduits and adjusted in and out of use by the hopper-carryinghinged frame.

3. The combination, in a corn-planter, of the curved hinged openers and their connected hoppers, carried by the hinged frame which carries the slide-operating mechanism, with the curved slotted shoes rigidly attached to the main frame and terminating in coverers which form a continuation of their bearing surfaces.

4. In a corn-planter having a shoe or runner at each end, the combination, with the slotted shoes B a, of the cutters or openers E, hinged at b to the shoes and operating in said slots a, the hoppers D, carrying the openers E, the hopper-carrying frame F, and the lock-bar G, whereby the cutters are adapted to be put into or out of operation, substantially as described.

5. In a corn-planter having a shoe or runner at each end, the combination, with the slotted shoes B a, of the cutters or openers E, hinged at b to the shoes and operating in said slots a, the hoppers D, carrying the openers, the hopper-carrying frame F, the lock-bar G, and the lock it on the main frame, whereby the cutters or openers may be held to their work below the slots, or held above the slots in moving from the field, substantially as described.

6. In a corn planter, the slide-operating frame K L, hinged to the hopper-carrying frame F, as described, in combination with the lever I, pivoted to the main frame A, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presenceof two subscribing witnesses.

JAMES WILLSON CLARK.
