FRANKLIN F. I-IARMAN, OF HONEY CREEK, INDIANA.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 394,176, dated December 11, 1888. Application filed July 26, 1888. Serial No. 281,096. (No model.)

To all whom it may concern.-

Be it known that I, FRANKLIN F. HARMAN, a citizen of the United States, residing at- Honey Creek, in the county of Henry and State of Indiana, have invented a new and useful Improvement in. Check-Row Corn- Planters, of which-the following is a specilication.

My invention relates to an improvement in check-row corn-planters; an d it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings,Figure 1 is a top plan view of a check-row corn-planter embodying my improvements. Fig. is a vertical longitudinal sectional view of the same, taken on the line m 00 of Fig. 1. Fig. is a detail view. Fig. t is a detail view.

A represents a portion of the frame of the planter, which comprises the parallel side beams, A, and the cross-Imam ll, connecting the same near their front ends.

C represents the axle, which connects the rear ends of the beams A, and to which is secured a pair of wheels, I) E. The former is provided on its inner side at its center with a circular disk or plate, F, which is provided with a series of radial openings, G, at its perimeter.

H represents a vertical standard, which projects from the axle at a suitable distance from the wheel I). From the upper end of said standard projects an outwardly-extending stud, I, to the outer end of which is pivoted a tappet-lever, K, one arm, L, of which is shorter than the opposite arm, M.

N represents a bell-crank lever, which is fulcrumed on the beam B near one end thereof, and is arrai'lged in a keeper, 0. A seedslide, P,,of the usual or an suitable construction, is arranged trau sversely on the front end of the frame and directed by guides or keepers R, and said seed-slide has aloop or keeper, S, which engages one end of the bell-crank lever N. The opposite end of said bell-crank lever is connected to the tappetlever K by means of a rod, T.

I' represents an operating-lcver, which is journaled near its center on the inner end of the hub of wheel D and bears against the circular plateF. From one end of the said lever projects an in wardly-extending tappetrod, V, which describes a circular path intersected by the shorter arm of the tappet-lever K, and another tappet-arm, \V, projects also from the inner side of the lever U, near the center thereof, and describes a circular path, which is intersected by the lower longer arm of the tappet-lever K.

X represents a lockinglever,which is pivoted to the lever ll, and has a cam or web, Y, atits inner end, which is adapted to engage either of the radial openings Gin the circular plate F, so as to secure the lever I to the said plate, and thereby cause saidlever to revolve with the wheel D. A spring, Z, bears between the lever U and the locking-lever X and maintains the latter normally in engagement with the plate F.

A represents a loop, which is pivoted to the lever U near one end, and is adapted to engage the outer end of the locking-lever X, when the latter is disengaged from the plate F, so as to lock the same against the tension of the spring Z out of engagement with the said plate.

I) represents a rock-shaft,which is arranged transversely under the front end of the frame and is journaled. in suitable bearings. From the ends of the said rock-shaft depend marking-teeth C, and from the upper side of said rock-shaft, near one end thereof, projects an arm, D.

E represents a lever, which is fulcrumed on the axle 0, near one end thereof, and has its outer end arranged in the circular path described by a pair of tappet-studs, F, which project from the inner side of the lever U 011 opposite sides of the center thereof. A spring, G, bears against the rear side of the lever E near its inner end, and a stud, l'I', serves to limit the motion of the said lever.

I represents a rod, which connects the inner end of the lever E to the arm 1) of the marker rock-shaft. It will. be understood that the spring G normally moves the leverE to the position illustrated in Fig. 1, and thereby causes the rod I to turn the rock-shaft forward, so as to normally raise the points of the markers from the ground.

The operation of my invention is as follows: When the machine is in motion and is being driven across a field, the revolving motion of the operating-lever U causes its tappet-arms V \V to alternately engage the upper and lower ends of the tappet or rocking lever K, so as to operate the same and thereby impart oscillating motion through the rod T to the bell-crank lever N. The latter being connected to the seed-slide, as before described, causes the same to reciprocate and thereby drop the seeds in hills at regular distances apart. Inasmuch as the studs F are in line with the tappet-rods V \V, the same are caused to engage the lever E at the same instant that the arms V V engage the tappet-lever K, and hence the markers are operated simultaneously with the seed-slide and caused to mark the hills of corn. \Vhen the locking-lever X is disengaged from the plate F, the machine is thrown out of gear and ceases to operate.

By means of the series of radial slots or openings with which the plate F is provided the operating-lever maybe secured to the said plate at any desired adjustment when arranging the machine at the end of the row or after passing an uneven place in the field, so as to cause all of the hills of corn to be planted in check-rows.

Having thus described my invention, I claim 1. The combination, in a check-row cornplanter, of the wheel D, the plate F, secured thereto and having the radial openings G, the operating-lever pivoted on the center of the wheel and having tappet-arms U V, the locking-lever X, pivoted to the operating-lever and adapted to engage radial openings in the plate F, for the purpose set forth, the planting mechanism, the tappet-lever K, having its arms arranged in the paths of the tappetarms, whereby said tappet-lever may be oscillated, the bell-crank lever N, connected to the seed-slide, and the rod T, connecting said lever to the lever K, substantially as described.

2. The combination, in a check-row cornplanter, of the driving-wheel, the operatinglever, means to secure the same to the driving-wheel,the 'tappet-arms U V, projecting from the operating-lever, the studs F in line with said tappet-arms, the tappet-lever K, arranged in the paths of the arms U V and connected to the planting mechanism, the rockshaft having the markers and the arm D, the spring-actuated lever E, having one end arranged in the paths of the studs F, and the rod I, connecting the lever E and the arm D, whereby the markers and the planting mech anism are operated simultaneously, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

FRANKLIN F. HARMAN.
