CORN-PLANTER.

SPECIFICATION forming part of Letters Patent N 0. 405,498, dated June 18, 1889.

Application filed February 19, 1889. Serial No. 300,425- (No model.)

T to whom, it may concern.-

Be it known that we, J AMES R. PATTERSON and lVIARSHAL T. FOSTER, both of Madison,

in the county of Greenwood and State of Kansas, have invented a new and useful Improvement in Corn-Planters, of which the following is a full, clear, and exact description.

Our invention relates to an improvement in corn-planters, and has for its object to provide a simple and effective check-row attachment for corn-planters, an improved device for reciprocating the seed drop-bar, and means for throwing the marker out of engagement with the ground when desired.

The invention consists in the novel construction and combination of the several parts, as Will be hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure l,is a plan view of the corn-planter. Fig. 2 is a central vertical section. Fig. 3 is a transverse section through the axle near one of the wheels, illustrating the said wheel in position to revolve freely upon the axle; and Fig. 4. is a similar View, in which the wheel is shown as geared to the axle.

In carrying out the invention the seedboxes 10, which may be of any approved construction, are located upon the frame 11, Which seed-boxes are provided with the usual form of reciprocating drop-bar 13. The frame 11 is supported upon runners 14, and to the rear of said frame a second frame 15 is hinged, the front cross-bar 16 of said rear frame being providedwith a vertical yoke 17.

In the rear frame 15 an axle 18 is journaled, having a crank-arm 19, formed therein opposite the frame-yoke 17, as best shown in Fig. 1, and at one end of the crank-arm a ratchet-wheel 20 is secured to the said axle. A lever 21 is loosely mounted upon the axle .provided with a dog 22, capable of engagement with the ratchet-wheel, which lever 21 extends, preferably, beyond the rear frame, and by elevating the lever the axle may be readily rotated.

Near each end of the axle 18, outside of of each drive-wheel, atopposite sides of the hub, a pawl 25 and 26 is respectively pivoted, which pawls are normally held in engagem cut with the ratchet-wheels 24 by means of springs 27 or equivalent devices, as best illustrated in Figs. 3 and 4.

Between each ratchet-wheel 24 and the opposed faces of the drive-wheels 23 a shiftingarm 28 is pivoted upon the axle, the ends of which arm are bent inward, as bestillustrated at a in Fig. 1.

\Vhenit is desired to permit the drivewheels to turn loosely upon the axle 18-as, for instance, in going to and from a field-the shifting-arm 28 is so turned that the ends (1,.

will be brought in contact with the pawls 25 and 26, disengaging them from the ratchetwheels 24, as illustrated in Fig. 3. This is ordinarily accomplished when the shifting-arm is located diagonally of the frame, and when the said arm is carried parallel with the frame,

as shown in Fig. 4, the pawls 25 and 26 are free to act. I

At the rear of the forward frame 11 a vertical shaft 30 is journaled in suitable bear ings 31, from the upper end of which shaft an arm 29 extends forward and is pivotally secured to the center of the drop-bar 13, as best shown in Figs. 1 and 2. To the lower end of the shaft 30 an arm 32 is secured, said arm being adapted to project at a right angle to the arm 29. To the outer end of the arm 32 is pivotally attached a pitman 33, which pitman is pivotally secured to the crank-arm 19 of the axle 18. The extremities of the axle 18 project outward beyond the hubs of the drive-wheels, and upon each extremity of the axle a marker 34 is rigidly secured, consisting of a bar equivalent in length to the diameter of the drive-wheel, and provided at each end with an outwardly-extending shoe 35, as best shown in Fig. l. The markers 34 being adapted to make an impression in the soil at each half-revolution of the wheel, the dropping-chute of the feed-box is preferably located at such a distance in advance of the The markers 34 are so attached to the axle.

that when the seed-aperture of the drop-bar registers with the similar aperture of the seedbox one shoe 35 will be in position to strike the ground. The lever 21 is used for dropping the first hill and-for adjusting the markers after turning, as it is evident, by the manipulation of the leyer 21, for instance, carryin g the same toward the front of the machine, the axle 18 may be revolved without turning the drive-wheels, whereby the seed drop-bar may be reciprocated while the machine is stationary. The lever 21 is adapted to be located adjacent to the drivers seat.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a corn-planter, the combination, with an axle provided with a crank-arm, a seed drop-bar, a vertical shaft journaled to the rear of the drop-bar, and connection betweenthe upper end of the said shaft and the drop-bar and the lower end of the shaft and the crankarm of the axle, of drive wheels loosely mounted upon the axle, a marker rigidly secured to the ends of the axle outside of the drive-wheels, a ratchet-wheel rigidly secured to the axle near the inner face of each drivewheel, and spring-actuated pawls pivoted to the drive-wheels and capable of engagement with the said ratchet-wheels all combined for operation substantially as shown and described.

2. In a corn-planter, the combinatiomwith an axle provided with a crank-arm,-a seed drop-bar, a vertical shaft j ournaled to the'rear of the drop-bar, and connection between the upper end of the said shaft and the drop-bar and the lower end of the shaft and the crankarm of the axle, of drive wheel's loosely mounted upon the axle, a marker rigidly secured to the ends of the axle outside of the drive-wheels, a ratchet-wheel rigidly secured to the axle near the inner face of each drivewheel, spring-actuated pawls pivoted to the drive-wheels and capable of engagement with the said ratchet-wheels, and a shifting-arm pivoted upon the axle between the ratchetwheels and the drive -wheels and having curved ends, substantially as shown and described.

3. In a corn-planter, the combination, with a seed drop-bar, an axle provided with a crank-arm, and a connection, substantially as shown and described, between the crank-arm of the axle and the drop-bar, of drive-wheels loosely mounted upon the axle, a ratchetwheel rigidly secured to the said axle near the inner face of each drive-wheel, and an intermediate ratchet- Wheel also secured 'to the axle, a marker secured to each extremity of the axle outside of the drive-wheels, pawls pivoted to the drive-wheelscapable of engagement with the outer ratchet-wheels of the axle, shifting-arms loosely mounted upon the axle and having curved ends, and alever held to revolve upon the axle adjacent to the intermediate ratchet wheel and provided with a dog adapted to engage with the said wheel, substantially as and for the purpose Specified.
