JOHN KAYLOR, OF DECATUR, ILLINOIS.

CHECK-ROW CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 269,584, dated December 26, 1882.

' Application filed September 5, 1881. (Model.)

To all whom it may concern Be it known that I, JOHN KAYLoP 'a citizen ot' the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented a new and useful Improvement in Check-Row Corn-Planters, of which the fol- 'low1ng is a specification.-

My invention relates to that class of seedplantersknownas check-rowplanters,adapt ed to traverse a rope having engaging buttons and secured at each side or end of a field; and the novelty consists in the construction and arrangement of the parts which operate the ratchet seed-disks and the-lower or second drops, as will be more fully hereinafter set forth.

By reference to the drawings which. form a part of this specification, Figure 1 is a top view of the planter, one of the plates being removed from the seed-box to show the teeth on the seed-disk and the mannerin which the pawl engages therewith, also one of the curved arms broken out to show the manner of connecting the lower drop with the transverse rod. Fig. 2 is arear elevation, partially in section, to show the interior of one of the seed-boxes and and one of the runners to show the lower or second drop. Fig. 3 is a side elevation showing the forward and upward curvature of the arm, and the lower part of the runner being in section to show the lower drop. Fig. 4 represents the two dogs enlarged. .Fig. 5 is a plan and longitudinal section of the plates which are secured to'the top of the longitudinal slide.

A represents the transverse beam, onto which the runners B B are bolted at the rear side, and upon which the seedboxes O G are secured so that the center of thebox will extend over the beam and connect with the upper part of the e, which intercept the knots or stops on the wire or cord, and are operated by them.

F is alongitudinal slide, placed between the seed-boxes and supported by groo ed rollers a a a a, (see Figs. 1 and 2,) which are pivoted to thelower or base plates, G. of the seed-boxes. The slide F is provided with pawls h h, which engage with the seed-disks I I, a spiral spring, I), being placed between the pawls to force them into position against the teeth of the seed-disk, so that hy each forward stroke of the slide F both of the seed-plates are moved one hole, and by the engagement of the slide with the dog H secured to the transverse rod, the second or lower drops are operated.

The curved arms E E are bolted to brackets cast-onto the outer side of the inclined portion of the runner B, and curve upward and forward in order to support the transverse shaft D on a line with the bottom and in front of the seed-boxes, as shown in Figs. 1 and 3. The forks or branches of these curved arms are provided with guide-pulleys to guide the cord or wire, as in other machines.

The seed-box on the right of Fig. 1 has the top plate, 5, removed, so that the perforated seed-plate with the ratchet-teeth may be seen. while the seed-box at the left has the cut-off plate i in proper position, and shows the pawl as passing under it to reach the teeth at. the seed-disk. In Fig. 2 the seed-box at the right is shown in section with the top plate, t, in position. Each box being alike, a clear showing of one covers the other. At the let't'of Fig. 1 the arm E is broken out, so that the lower drop and its connections with the rod D may be seen from the top, while in Figs. 2 and 3 the lower part of the runner is in section, showing an incline shelf, It, upon which the drop'k rests and retains the corn until, by the partial rotation of the rod D, through the the medium of the slide and levers O O, the drop is raised, as shown in I+ig.'3, allowing the cornto drop into the furrow made by the runner.

The rod D is supported by the lateral-projecting arms P P, which are bolted onto the beam A. The operation is as follows: The knotted wire or cord being placed into the fork e and over and under the guide-pulleys in the usual manner, as in other machines, the planter being drawn across the field brings the stops in contact with the fork a, forcing it back against the lug 6, partially rotating the shaft, at which point the knot slips over, and the fork is returned to its former position against the front stop, e, by the spring S. attached to the front end of the slide F. When the shaft is opera ed as described the dog H, passing up through the slide, moves it longitudinally, and the pawls h h thereto attached cause the seed-disks to rotate the distance of one tooth, and, there being a corresponding number of holes in the disk, each movement of the slide brings one hole directly over the opening in the bottom or base plate and allows the corn to drop down the runner to the lower or second drop, which retains it until the slide is again operated. It will be seen that this lower drop is raised at each longitudinal stroke of the slide by the dog H The runners rise perpendicular ashort distance and then incline toward the center of the machine, so that the seed-boxes may be placed sufficiently close to ad mil; of the slide being supported by them in the manner shown. In brief, the check-row planter is operated by a knotted wire or cord stretched across the field by its action upon the fingers of a transverse sha'ft,which operates alongitudinal slide placed between the seed-boxes, carrying two pawls for operating the seed-disks, said slide also operating the lower or second drops through the medium of a transverse rod and arms thereto attached in the manner as herein set forth.

I am aware that prior to my invention transverse shafts having forked levers secured to their outer end to engage with the knots or stops of a wire or cord have been used in connection with many different devices for the purpose of operating the seed-slide or shakebar of a planter. I therefore do not broadly claim such a combination; but

What I do claim, and desire to secure by Letters Patent, is

1. In a check-row planter provided with a transverse shaft having forked levers at each of its ends to intercept the knots or stops on the wire, the combination therewith of a longitudinal slide, F, supported by rollers pivoted to the base-plates of the seed-boxes, as shown, and bearing pawls h h, which engage with the teeth ofthe seed-disks, substantially as and for the purpose herein set forth.

2. In a check-row planter, the combination, with the transverse shaft D and longitudinal slide F, of the transverse rod D and dog 11 secured to said transverse rod and adapted to engage with the slide F, as shown,through the medium of which an intermittent oscillatory motion is imparted to the transverse rod D, substantially as and for the purpose described.

3. In a rheck-row planter, the combination, with the transverse shaft and slide F, of the dog H, secured to said shaft and adapted to engage with said slide and to transmit a longitudinal movement thereto by the engagement of the knots or stops on the wire or cord with the forked levers at the ou er ends of the transverse shalt, as he-rein set forth.

4. The combination, with the runners -B B,

bolted onto the back side of the beam A, of the curved and forked arms E E, secured to the inclined portion of the runners, as shown, said arms being curved upward and forward for the purpose of supporting the transverse shaft D on a line with the slide F, and in front of the seed-boxes, the forked portion of said arms being provided with lugs or stops 6 e, and surmounted by guide-pulleys, substantially as shown, and for the purpose set forth.

In testimony whereof I have hereunto subscribed my name.
