CORN-PLANTER.

SPECIFICATION formingpart Of Letters Patent No. 246,4?8, dated August 30, 1881.

Application filed June 27, 1881. (No model.) I

To all whom it may concern Be it known that I, FRANCIS O. FROST, a citizen of theUnited States, r esidentof Anoka, in the county of Anoka and State of Minnesota, have invented a new and valuable Improvement in Corn-Planters; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical central section of my device, with the dropper in position to receive seed. Fig. 2

is a similar view, showing the dropper in the 7 act of discharging the seed; and Fig. 3 is a sectionalview, showing one ofthe inside plates.

This invention has relation to hand cornplanters; and it consists in the improved features of construction and combination herein after fully described, and particularly pointed out in the claiman improvement of Letters Patent No. 219,573, granted to me September 16, 187 9.

In the accompanying drawings, the letterA designates the hollow body of the planter, forming the seed-holder, slotted in front at b and in rear at c.

1) represents the interior slotted guide-plate, which is provided with the convex rib or flange c, and is secured to the inner wall of the box A,nearits lower end. A pair of these plates is employed for each box, usually said plates forming the bearings for the journals 9 of the rocking dropper H. The dropper is cylindrical or partially cylindrical in form, and is recessed at k to receive the seed to be dropped at each discharge. The quantity of seed taken in by the recess is regulated by means of the adjustable block or section I of the discharger m. The latter is provided with a lateral pin or pins, a, which are designed to engage with the curved slots 8 of the plates D, and as the rocking dropper is moved back and forth said discharger is moved to the mouth of the recess, and reversely. Adjustment of the section lot the discharger is effected by means of the threaded stem 1 thereof, which engages with a threaded hole in the discliarger. A slot, 8,

is made in the side wall of the recess 76, to allow for the movementof the pin of the discharger, as indicated in the drawings.

Bearing on the rear portion of the perimeter of the dropper is a brush,p, which is secured to the strip q, which closes the rear slot. 0, of the box A. The slot 0 forms a channel or way in rear of the dropper, through which the seed from the discharger falls into the lower end of the box, passing thence out through the opening t.

Secured to the lower end of the box, on its front, is a spade, V, and a stop, to, is provided near the upper end of the blade, below the level of the opening t, which is in rear of the spade, so that said opening will not be carried down into the ground, but will be free at all times for the outward passage of the seed. The upper end of the spade forms a bearing, 2, against which the lower end of the reciprocating handle-slide E abuts when the spade is being pushed into the ground. The handleslide E is connected to the box by means of straps F, and is provided with a center guide and stop, G, which works in the front slot, b, of the box, as indicated in the drawings. An inner strip, K, serves to prevent the slot 1) from being clogged with seed.

The handle-slide is provided usually with a rear shoulder, L, which is designed to engage the top of the box at the same time that the lower end of said slide engages the top of the spade, and serves to assist in the downward pressure.

The operation is as follows: The planter is swungi'orward by means of its handle, and the spade pressed in to the soil in a forward oblique direction, the handle-slide being at the same time moved downward, in order to give the necessary pressure. This movementrocks the dropper forward by means of the lever-pin 3 engaging a slot in the slide, and the recess therein passes in front of the brush into proper position to receive seed. Then the planter is carried forward at its upper end, assuming a more upright position and opening the ground in rearot' the spade. Then the handle-slide is drawn up, turningthe dropper so that the seedrecess will pass in rear of the brush and the seed will be discharged, passing out at the opening 25 into the opening in the ground, the mouth of which is, in this position of the plantstop secured to the front of the spade below the opening t to prevent the opening from being clogged or closed when the spade is thrust into the ground, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
