JOHN KAYLOR, OF DECATUR, ILLINOIS.-

CHECK-ROW CORN PLANTER.

EPECIFIGATION forming part of Letters Patent No. 340.511, dated April 20, 1886.

' Application filed January 52,1886. Serial No. 187,444. (No niodell) To aZZ whom it may concern.-

Be itknown that I, JOHN KAYLOR, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improve ments in Check-Row Corn-Planters, of which the following is a specification.

The main features of my invention relate to check-row corn-planters of that type which are actuated by the check-rower devices on the moving planter coming in contact with indexes or tappets on a check-line which is stretched adjacent to the path of the moving planter across the ground to be planted.

Some of the features of my invention, however, relate to improvements which may be used in planters in which the seeding devices are operated either automatically or by hand.

These different features of invention are hereinafter fully described, and are summarized and pointed out in the claims hereto anncxed.

In the accompanying drawings,which illustrate one method of embodying the different features of my invention in a. single practical check-row corn-planter, Figure 1 is a top plan of the planter, shown with one seed-box removed and the tongue and seat-supporting bar partly broken away. Fig. 2 is a side elevation of the planter, shown in position for planting, but the rear wheel removed, the axle in section in line 00 x in Fig. 1, and the tongue partly broken away. Fig. 3 is an end elevation of the check-rower rock-shaft and a side elevation of one of the forked levers. Fig. 4 is an elevation of the forked lever and the check-row rockshaft in section, seen at right angles from the View of the same parts shown at Fig. 3. Fig. 5 is an enlarged sectional elevation of the lower end of the planter seed-tube and its contained parts. Fig. 6 is a sectional plan of the seed-tube in linear a: in Fig. 5. Fig. 7 is a side elevation ofthe planter, showing all its parts elevated and supported onthe traetionwvheels forlocaltransportation, the tongue shown broken away, the near trac tion-wheel removed, and the axle in section, as at Fig. 2. Fig. 8 is a sectional plan of one of the seed-boxes in the plane of the line a: m in Fig. 10, showing the seed-cup wheel in plan, and the cap-plate ordinarily aboveit removed.

Fig. 9 is same plan as 8, butshowsthe parts in different relative positions from those shown at Fig. 8. 'Fig. 10 is same plan as Fig. 8, but

further shows the slide-bar with its upper portion removed, to show the spring-actuated integral pawl and detent. Fig. 11 is a sectional elevation of the seed-box, showing the slide bar, its supports, and the integral pawl and detent in elevation.

In so far as the frames ofthis planter are concerned, it is one of that class in which a forward frame mounted on runners or furrowopeners and carrying the seed-boxes is hinged to a rear frame which is supported on the traction-wheels, and one of that particular kind in said class in which the forward end of the forward or runner frame is hinged to the extended forward end of the rear or wheel frame. a

The rear frame, A, is formed in an ordinary manner of an arched axle, A, supported on wheels A,side bars, A, fixed to the axle A, transverse bars, A, and brace-bars a, and supports a seat, B, on bars b b, which rest on and are secured to the bars A.

The forward frame consists of the runners or furrow-openers O, seed-tubes G, transverse bar 0 at the forward end of the forward frame, braces c, a rear transverse bar, D, and a tongue or draft-pole, D, which parts are constructed and combined with other parts in an ordinary manner, except as hereinafter otherwise specifically pointed out and described.

The extended rear-frame side heads, A, are connected by ordinary hinges, a,with the bar 6'', so as to-permit the forward frame to rise and lower at its rear end, or to swing in a vertical plane on the hinges a and the at tachment to the neck-yoke, and to permit of the rear frame being oscillated on the axle when the forward frame is raised, to permit and to aid in raising the forwardframe. The tongue D is fixed to the bars D and G. The forward and upper end of each runner O is bolted between bars 0, which extend upward ISO A, as shown at Fig. 1. A branch, 0", ex tends from the seed-tube and connects with the bar D. Thus the parts of the forward frame are connected with each other, as last described.

The bar D is extended laterally beyond the runners to form a support on which the checkrower devices are carried, as hereinafter described, while it forms, as already described, one of the main-frame bars of the runnerframe of the planter.

The lower half or portion of each seed-tube is vertical, and the upper part inclined rearward toward its upper end, where it has flanges e, by means of which it is bolted to the seed-box E.

Each seed-tube has a pair of levers or bars, FF, one bar on each side of the seed-tube, and'each passed loosely through aslotted ear, f, on its respective side of said tube. The bars F converge forward of the seedtube, and are there fixed to a single bar, which forms a continuation or extension of said bars F and passes through between the bars a", where it has a series of holes, f, through one of which a bolt, f, passes, and near same point the bars 0" have a series of holes, f Pendants F, near the rear ends of the bars F, carry an axial bolt, f on which is journaled awheel, G, which by these means is carried in rear of and in the path of the seed-tube.

H is a shaft which extends transversely across the rear frame of the planter in rear of the axle A, and has suitable hearings on said frame. The shaft H has a crank-arm, h, on each of its ends, and the outer ends of these crank-arms are connected by rod-links h, one with the rear end of each pair of bars F. The shaft H carries a segment-gear. h, which gears with another segment-gear, i, carried on a short shaft from which a hand-lever, I, extends upward to within convenient reach of the driver when in the seat 13. The handlever I is provided with an ordinary springactuated pawl, t, operated by an ordinary thumb -piecc, 1'". By drawing the thumb piece 12 toward the lever I the open link 2" may be thrown over said thumb-piece to hold the pawl-t" out of engagement with the rackbar l,which is fixed to the rear frame for its engagement,for purposes hereinafter described.

The bar D has fixed to each of its ends a crosshead, d, on each of which is fixed the ordinary forward guide-pulleys, d, and rear guide-pulleys, d", for the check-row line J, which carries the ordinary tappets or dropping-indexes j.

K is an ordinary roclcshaft journaled in suitable hearings, in, which are fixed to the heads (1, and has a forked lever, 70', on each of its ends. Each forked lever k is loosely mounted on the tubular shaft K, and is held from sliding lengthwise on said shaft by a staple, k", which is secured to the rockshaft, as shown at Fig. 4. A lug, k, projects from the lower end of the forked lever beyondthe staple k. As the forked lever is moved by a tappet in the direction shown by the arrow at Figs. 2, 3, and 7, the lug It will, by contact with a staple it, give a partial rotation to the rock-shaft in the same direction, and as the rock-shaft is swung or rotated backward in an opposite direction to that last described by the spring I the staple will act on the lug to give the return movement to the forked lever.

When the rock-shaft is moved, as last described, by one forked lever, the other forked lever will remain still, as shown at Fig. 3, where the dotted line position of the lug 75' indicates its movement away from the staple shown, as supposed to be given it by the forked lever not shown, while the forked lever shown at same figure remains still. This manner of mounting the forked lever and transmitting motion from it to the rock shaft also permits the lever to swing laterally, as shown by dotted lines at Fig. 4, the well-known advantages of which need not be herein stated.

A crankarm, Z, projects from the shaft K, forward of and in line with each seed-box, and a rod-link, 1, extends from each crank Z to, and connects it with a slide-bar, M, which passes through the seed-box about in same horizontal plane and near to one side of the seed-cup wheel N, which is centrally journaled, so that it can rotate, and is provided with ordinary seed-cups, n, and ratchet-teeth n-one to each seed-cu p.

Figs. 8 to10, inclusive, show the seed-cup wheel, but do not show the cut-off and capplate which covers the seed-wheel, and which may be of any ordinary or desired construction, and hence need not be herein shown or described.

The slide-bar M runs between guides m at one end, and is suspended by a swinging bar, m, at its other end, which reduces the friction. The swinging bar m is pivoted atone end to the slide-bar M, and at its other end to the seed-box. (See Fig. 11.)

P is my combined pawl and detent, formed of a pawl end, p, and a detent end, p, about at right angles to its pawl end. This pawl anddetent 1s located in a slot in the slide-bar M, (see Fig. 1 1,) and is pivoted therein by a bolt, m", near the angle or bend between the detent and the IMIWI'ZLIIDS. A spring-plate, m, fixed to the slide-bar M, presses the pawl end 1) toward the seed-cup wheel.

Q is a springplate detent, attachedat one end to the seed-box, and at its other end located so as to come in contact with the ratchetteeth on the seed-cup wheel. The bar m is located in a space formed by a partition, 6, and the side of the seed-box, which partition keeps the corn in the seed-box from contact with said bar, and the position of which is indicated by dotted lines at Fig. 9.

As a forked lever is moved rearward by a tappet, arectilinear motion is given the slidebars M in the direction shown by the arrows at Figs. 8 to 11, inclusive, and the pawl 11 is.

thus made to act on one of theratchet-teeth, and thereby give apartial rotation to the seedcup wheel in the direction shown by the arrow at Fig. 8, and thus bring a seed-cup in each wheel in register with and in position to discharge its contents through the opening 6' in the bottom plate of the seed-box into the throat of the seed-tube.

When the throw of theslide-bar M and seedcup wheel are completed. as last described, the detent 1) will be brought in contact with the sloping side of one of the ratchet-teeth on the seed-cup wheel, and will thus arrest the motion of said wheel at the proper time and prevent its momentum carrying it too far for the proper registry of the discharging seedcup with the opening e, and the spring-detent Q- will at the same time drop behind one of the ratchet-teeth and prevent any backward movement of the seed-cup wheel, as shown at Fig. 8.

When the springl returns the rock-shaft, as hereinbefore described, and thus with draws or moves the slide-bar Min an opposite direction from that last described, and as shown by the dotline arrow at Fig. 9, the spring m' will allow the pawl 19 to yield and rise over the ratchet-tooth in rear of the one it last acted on, as shown plainly at said Fig. 9.

When the throw of the slide-bar M in the direction last described is completed, the combined pawl and deteut will be brought approximately into the position shown at Fig. 10, and ready to again act on the seed-wheel, as hereinbefore described, when the slide-bar again is moved in the direction of the arrow shown at said figure.

The movementof the slide-bar M in one direction is limited by the shoulders m on said bar coming in contact with the guides at, and its movement in the opposite direction is limited by the movement of the rock-shaft K, which is limited by the forked levers coming in contact, respectively,with an adjacent pro- 5 jecting arm, d, from a head, d.

The vertical lower end of the seed-tube is divided into two compartments by a partitionplate, 8, to near the lower end of said tube, (see Fig. 5,) and the bottom or lower end of the duct 8, formed by said partition and the rear side of the tube, is terminated by a shelf,-

s, which inclines downward and forward, as plainly shown at same figure. The lower end of the plate 8 does not quite extend to the lower end of the inclined discharging-shelf s, and thus leavesadischarge-opening, s', which is opened and closed by a discharging-valve, t, as hereinafter described. The valvet slides vertically in a duct, 8', formed in the seedtube forward of the plate 8, and is operated by the rock-shaft K by means of a crank, it, which extendsdownwardly from the rockshaft and is connected by a link-rod, a, with one end of a bell-crank lever, to, the other end of which is connected by a link-rod, u', with the valve t. The upper end of the rod 10" passes through a hole in the upper end of the plate s,which upper end is enlarged to close the upp r end of the duct in which the valve t slides. The bet-crank lever a is pivoted at its bend to the branch 0 of the seed-tube. By these means the valve t will be drawn upward and the discharge 8' immediately opened, when a forked lever is forced rearwardly by one of the tappets'on the check- -line, and the seed contained on the shelf 8 will escape and be thrown forward, by the forward and downward inclination of said shelf, with a velocity about equal to the velocity at which the planter may be moving, whereby they will be dropped more nearly as if dropped from a stationary tube, and will 'not be scattered, as when discharged vertically or rearwardly from the tube. The seedcup wheel is not operated fully and so as to discharge'a charge of seed until the forked lever has about completed its throw rearwardly; hence the forked lever is given its return-throw by the spring I in time to lower the valve t and close the opening 8' and catch the charge of seed which was discharged by the seed-wheel from the forward throw of the forked lever.

The seed tube O is formed in two parts-a front and rear part-united about on a line with the valve 12. The front part of-the seedtube is extended and forms the branch 0, and the rear part is extended, and the front and inclined side of its upper end is formed of woven wire, to, through which the interior of. the seed-duct may be seen in order to know if the seed-cup wheel is measuring and discharging regularly. The front and rear parts of the seed'tube are held together by a bolt, y, which passes through the lugfand another lug, 9''. (See Figs. 2 and 7.)

The wheels G not only act as coveringwheels in the ordinary manner, but also gage. the depth of penetration of the soil by the runners (J, and hence gage and control the depth of planting, whereby the different charges of seed may be deposited at uniform depths. The forward end of the bars F may be adjusted at higher and lower points on the bars 0, and

held after adjustment by the bolts f, for the purpose of raising and lowering the wheels G relatively to the runners O, as shown by dotted lines at Fig. 2, and thereby regulating the depth of planting, as here'inbefore referred to. The different holes f in the bar F will enable the adjustment referred to to be accomplished in an evident manner. \Nhen the bars F are adjusted as last described, and as shown by the dotted lines referred to, the lever I may then be adjusted to bring the wheels G to the surface of the ground in planting, and by engaging the pawl i with the segment rack-bar l the lever I will be locked, and will lock the front and rear frames of the planter to each other, and thereby hold the runners in the soil, to the depth controlled by the wheels G. By engaging the link 2" with the thumb-lever i the pawl t" will be held out of engagement with the rackbar l, and the flexible connection-joints a will then permit either the forframe in the elevated position shown at same figure, in which position the front and rear frames may again be locked rigidly together by the lever l, as hereinbefore described, and the rear frame will support the weight of the forward frame without any neckdraft or pressure on the horses necksfor local trans portation, while the planter is being turned round at ends of rows, moved from field to field, or for any other necessary purpose.

The last-described function of my invention arises mainly from the fact of the tongue or draft-pole D being bolted to the forward frame instead of to the rear frame, as is com mon in this type of planters, in which the rear frame is hinged to the forward end of the forward frame.

The lever I may be connected directly to the shaft H and operate it without the gears t It. as will be readily seen by any one skilled ih this art.

I do not deem it necessary herein to point out different modifications which may be made of several of the main features of my invention, nor to describe different combinations that some of the features may be easily adapted to, nor do I intend by so doing to limit my claims to include in either of them elements or parts not recited therein; and,
