CORN-PLANTER.

SPECIFICATION forming part of Letters Fatent N 0. 605,039, dated May 31, 1898.

7 Application filed January 25, 1898. Serial No. 667,874. (No model.) I

To all whom it may concern:

Be it known that I, SAM EL M. WIxoEL, of Marcus, in the county of Cherokee and State of Iowa, haveinvented a new and useful Improvement in Corn-Planters, of which the following is a full, clear, and exact description.

The invention relates to an improvement in corn-planters, and especially to checking and marking devices employed in connection with such planters.

The object of the invention isto provide a device to be used as a substitute for the checkwirenamely, a belt contained in its entirety ,struction .and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims.

A machine. Fig. 2 is a plan view of the same,

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi cate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved the seedboxes being omitted. Fig. 3 is a vertical section taken substantially on the line 3 3 of Fig. 2. Fig. 4 is a vertical trans verse section on the line 4 4 of Fig. 3, and Fig. 5 is a plan view of the hoe. I

The frame of the machine usually consists of parallel front and rearbars 10, connected by end bars 11, brace-bars 13, which extend from the main frame, converging at their forward ends to meet a U-shaped horizontal arm 14, secured at its rear end to a front crossbar, and the tongue is secured between the members of the arm 14. The main frame is supported upon runners 12, and the runners are provided with the usual shoes to deliver the seed, receiving the seed from seedboxes of any description, located one over each runner, a seedbox being indicated by dotted lines in Fig. 1. Hangers 17 are secured to the rear cross-bar of the frame and the seeddrop shaft is journaled in these hangers and is designated as 16. A crank-arm 18 is usually formed at each endof the seed -drop shaft 16, and each crank-arm is shown as pivotally attached to a connecting-rod 19, the said rods being adapted for attachment to the valves in the seedboxes, to open and close the same by the movement of the said shaft 16.

Near the center of the seed-drop shaft 16 a lever-arm 20 is secured, extending preferably a greater distance above the shaft than below it, as shown in Fig. 3, and a spring 21 is attached to the upper end of the lever-arm and to a rearward extension 13 from the frame, normally holding'th'e upper end of the lever inclined rearwardly. The rear extension 13 of the frame is adapted for attachment to any wheeled support, and any known mechanism may be employed for raising and lowering the frame of the machine. A connecting-rod 22 is attached to the lower end of the leverarm 20 and to a crank-arm 23, forminga portion of a shaft 24, which shaft is journaled usually in the arm 14 at a point in front of the front bar 10 of the frame, the shaft being shown best in Figs. 2 and 4, and posts 45,

preferably two in number, are carried upward from the shaft 24,between the members ofthe arm in which the shaft is journ'aled.

-At orabout the center of the front bar 10 of the frame'an arch 25 is secured to the upper surface of the said bar, as illustrated in Figs. 3 and 4. An angle extension 26 from a tube 27 is pivoted to the central portion of the said arch 25, as shown in Fig. 2, the said tube forming a portion of the marker A. The tube is of sufficient length to extend beyond the end of the frame, as shown in Fig. 2, and the outer end of the tube 27 is secured to a runner 28, which is preferably pointed at its forward end and is connected at said end by a rod or a chain 29 with the tongue 15. The runner 28 is designed to make a mark which will serve as a guide in driving the machine across a field.

A shaft 30 is loosely mounted in the tube 27 and is' likewise loosely carried through the runner 28, the shaft 30 at its outer end being ICO provided with an arm 31, which is at right angles to the body and parallel with the runner 28. The crank-arm 31 of the shaft 30 extends beyond the rear end of the runner 2S and is preferably exteriorly threaded in order that a hoe preferably made with inclined sides, maybe adjustablysecured to it.

The hoe is shown in detail in Fig. 5 and is placed on the crank-arm 31 with its shorter end uppermost. A guard 32 is attached to the runner 9S,and said guard may serve to prevent the earth entering the opening through which the marker-shaft 30 passes and interfering with the working of the shaft, but is especially adapted to maintain the shaft 30 in position. A crank-arm 34' is secured to the left-hand end of the marker-shaft 30, as illustrated in Figs. 1 and 3, and the said crankarm 3i is connected by a rod with the up per portion of the lever-arm 20, located on the seed-drop shaft 1 (i. Thus whenever the seeddrop shaft is turned, which is accomplished by the forward movement of the shaft 24:, the upper end of the lever-arm will be carried forward, the rod 35 will likewise move forward, together with the crank-arm 34, and the marker-shaft will be turned in a direction to carry the hoe into the ground to make a mark, the hoe being normally held out of contact wit-h the ground by the spring 21.

At each side of the center of the machine parallel plates 30 are secured to the frame, extending in direction of the front and of the rear of the machine, and each plate 36 is preferably provided with an inwardly-extending flange 37 at its lower edge, as shown in Fig. at. A forward sprocket-wheel 38 and a rear sprocket-wheel 39 are journaled respectively in the front and rear portions of the said plates 36, the bearings of one of the said sprocketwheels being adjustable, as shown in Fig. A chain belt t0 passes over both sprocketwheels, and the said chain belt is designed to take the place of the check-wire ordinarily employed in connection with corn-planters. Sundry of the links of the chain are provided upon their outer faces with ears 41, the ears being arranged in groups of two pairs, as shown in Fig. The distance between the pairs of ears will correspond to the distance between the hills planted by the machine.

In one pair of cars a brace rod or barat2 is pivoted between its center and one end, the shorter end of the bar being adapted to engage with the chain when the longer end is carried away therefrom. Between the second pair of ears of a group one end of a stake 4:3 ispivoted. Thestakesandlikewisethebracebars 4.2 are preferably made of steel. The stakes are free to move upon their pivots either forward or rearward, so as to lie in either direction flat upon the chain. On the lower stretch of the check-belt the stakes assume a vertical position, as shown in Figs. 1, 3, and t, and the brace-bars 42 provided for the stakes at the lower stretch of the belt will drop downward at their longer ends and bear against the back of said stakes, the upper shorter ends of the brace-bars resting against the belt. Thus the stakes are held vertically while they remain beneath the machine except at the extreme rear end of the said machine, or when the brace-bars are ascending the rear wheel 3.), at which time the brace-bars will rest upon the belt and the stakes will drop forward and likewise rest upon the belt, so that on the upper stretch of the belt thebraeebars and the stakes will be practieallyparallel with said stretch, the longer ends of the brace-bars resting upon the pivot portions of the stakes to which they belong, as shown in Fig. i). The brace-bars a2, in addition to holding the stakes in any upright position in the ground, also serve to hold the stakes at a proper angle to enter the ground.

A predetermined number of the pivots tl provided for the stakes are made to extend outward beyond the sides of the belt, as shown in Fig. 4, so that as the beltis made to travel in a forwardly direction the projecting ends of the longer pivots it will engage with the posts 45, extending upwardly from the front shaft 2-1;, and will rock the said shaft and thus communicate movement through the connecting-rod 22 and lever-arm 20 to the seed'drop shaft 16, the movement of the shaft 16 being sufficient to open the valves of the seedboxes and effect a dropping of the seed.

It will be observed that the wheels 38 and 39 are turned by the movement of the chain and that the movement of the chain is effected by the advance of the machine, the stakes on the lower stretches of the belt entering the ground and remaining in. the ground a predetermined length of time. The hoes 323 are so adjusted that they will be in line with the heels of the planter-shoes.

The machine is exceedingly easy to operate, and the driver is not required to dismount from the machine when said machine is to be turned and another row is to be started.

The operation is practically as follows: XVhen the end of a row is reached, the marker A is swung to the otherside of the machine, and the machine is turned around, the frame of the machine having been raised, and when the frame of the machine is elevated the lower stakes 43 will be carried out from ongagement with the ground, since the lower stretch of the chain or belt travels along the upper surfaces of the flanges 37 on the checks or plates 30, as shown in Fig. 4. The machine having been turned around, it is simply necessary to grasp the belt and to pull said belt rearward untilone of the stakes provided with an extension pivot L1: is brought over the mark from which the row is to be started. The planter is then lowered until the stakes enter the ground and is then drawn ahead. The longer pivots it will contact with the posts 45 and operate the seeddrop shaft 10, corresponding to the knots that are formed upon the usual cheek-wire.

This machine is exceedingly simple. It is durable, and it is economic and does not require the setting up of a check-wire, its marking and guide mechanism being contained entirely upon the machine, so that no extra preparation is necessary when the field is reached, it being simply necessary to lower the frame of the machine and drive ahead. The form and location of the guide-flange 37 for the belt 40 may be changed as required by the character of frame employed.

- Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a planter, a marker consisting of a tube adapted to be pivoted to a support, a runner attached to the tube, and a shaft extending loosely through the tube and through the runner, the shaft being provided with a crank-arm parallel with the runner and arranged to receive a hoe, as and for the purpose set forth.
