CORNBPLANTER AND 'CHECKQROWER.

SP3 CIPICATIGN' '31 Application filed May 3, 1887. Serial No. 236,9C0. (N'o model.)

To all whom it may concern:

Be it known that we, JOHN \VESLEY OMA- HAN and EDWIN STANTON WHrr'rEMoRE, both of Huntingdale, in the county of Henry and State of Missouri, have invented a new and Improved Corn-Planter and Check-Bower, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved corn-planter and checkrower which is simple and durable in construction and very effective in operation.

The invention consists in the construction and arrangement of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claim.

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

Figure 1 is a plan view of our improvement, parts being in section. Fig. 2 is a sectional side elevation of the same on the line as a: of Fig. 1. Fig. 3 is a vertical crosssectional elevation of part of our improvement on the line 3 y of Fig. 1. Fig. 4 is a sectional end elevation of part of our improvement on the line 2 5, Fig. 1. Fig. 5 is a sectional side elevation of the same on the line 20 w of Fig. 4. Fig. 6 is a sectional end elevation of the seed-box frames on the line a a of Fig. 2, and Fig. 7 is a plan view of one end of the seed-box frame with the seed-box removed.

On the suitably-constructed frame A is so cured the axle or shaft B, on the ends of which are mounted loosely the driving-wheels G and O, of which the driving-wheel O is provided on itsinnerhub with aclutch-wheel,D,adapted 0 to engage a clutch-wheel, E, formed on the hub of the cam-wheel F, mounted loosely on the part B of the axle B. The cam-wheel F is provided with three projections, F, in its rim, adapted to engage alternately the frictionroller G, mounted on one end of the lever G, fulerumed on the main frame A, and engaging with its other end the slotted arm H, secured to the bar H, adapted to slide sidewise on top of the seed-box frame 1', pivotally connected with the main frame A.

The two ends H of the sliding bar H are reduced and slide in suitable grooves formed in the bottom of the seed-boxes K, of suitable size, and held on the outer ends of the seedboX frame I. In the center of the bottom of each seed-box K is pivoted a slide, L, provided with a slot nearits outer end, which engages a pin, H, secured to the top of the reduced part H of the sliding bar 11. In each of the slides L is also formed an aperture, L, adapted to register with a vertical slot, J, formed in the rear end of the plow J, secured to the outerend of the seedbox frame Ldireetly below the seedbox K. In the slot J is pivoted the lever N, forked at its upper end,and engaging with this end the pin H, secured to the inside of the reduced part H of the sliding bar H.

The lever N is so arranged in the slot J that when its upper end is on one side of the slot J then the lower end of thelevcr is at the opposite side of the slot, and when the bar H moves sidewise then the relative positions of the upper and lower ends of the lever N are correspondingly changed from one side of the slot to the other. The sidewise motion of the bar H also imparts a swinging motion to the slides L by means of the pin H so that the apertures L open into the slots J and deliver grain to said slots from the seed-boxes K. Near the middle of the sliding bar H, and extending downward, is secured a toothed rack. O, meshing into the segmental teeth 0, formed on the upper end of the lever O, fulcrumed on the seed-box frame I and extending downward, being pointed at its lower end,which is adapted to mark in line with the respective hills into which the grain has been dropped when the levers N were actuated by the sliding bar H.

On the inside of the camwhcel F is formed a hub, F grooved at its rim, which is engaged on its upper side by a semicircularly-grooved rim formed on the disk P, mounted loosely on the part B of the shaft B. Against the outer face of the disk P presses one end of the spring P, coiled on said part B of the shaft B, and 95 resting with its other end against the shoulder formed on the shaft B. This spring P has a tendencyto press the clutch E ofthecam-wheel F into contact with the clutch D of the-main driving-wheel G. From the face of the disk P project inward two arms, P pivotally connected by the links Q, with the forked end of the lever It, extending upward and being fulcrumed on the main frame A.

The operation is as follows: The operator occupying the seat S, secured to the main frame A, can move the cam-wheel F in and out of contact with the main driving-wheel C by moving the forked leverRsidewise,so that the links Q impart a sliding motion to the disk P,which,

by its semicireularly-grooved rim, moves the cam-wheel F sidewise on the part B of the shaft B. When the cam-wheel F is in clutchcontact with the main driving-wheel O, and the frameis moved forward in the direction of the arrow at, then the main drivingwheel O imparts a rotary motion to the cam-wheel F, whieh,by its projections F, imparts a sliding motion to the bar H by means of the lever G. As the cam-wheel Fis provided with three projections F, it will be seen that for every revolution of the main driving-wheel C said camwheel F imparts a sliding motion to the bar H three times. The sidewise-sliding motion of the bar H imparts a swinging motion to the slides L by means of-the pins H and at the same time the bar H imparts a rocking motion, by means of the pins H", to the levers N in'the slots J of the plows J. The levers N stand parallel to each other, and in such a relative position at their upper ends to the apertures L that the latter drop, on their swinging motion, corn into the slots J at every sidewise motion ofthe sliding bar H. The grain dropped into the slots J is retained in the same by the levers N, and is only delivered to the ground at the next shifting motion of the-levers N, imparted to the same by the sliding bar H. Then the grain passed from the seed-boxes into the slots J by means of the slides Lis retained in said slots J until the next sidewise motion of the levers N, and then the grain in both slots is dropped simultaneously into the furrows formed by the front end of the \plows J. At the same time that this takes place the bar H imparts, by its rack 0, an oscillating motion to the lever 0, so that the latter forms with its pointedlower end a small furrow in the ground between the two hills in which the grain had been dropped, as above described.

' If the operator desires to interrupt the sliding motion of the bar H, thus preventing the seed from dropping into the furrows, he moves the upper end of the lever R outward, whereby the links Q, pull onthe disk P, which, by its semicircularlygrooved rim, pulls the camwheel F inward, whereby the clutch E is disengaged from the clutch D of the main driving-wheel G, and the latter rotates without rotating the cam-Wheel F. It will be seen that at the moment the grain is dropped into the furrow from the two seed-boxes K the hills in which the seed has been dropped are marked by the scraping-lever O.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- The combination, with the frame, the drivewheels, axle, grooved cam-wheel F thereon, provided within the groove with the three projections F, and a clutch mechanism for said cam-wheel,of the horizontally-oscillating lever G, entering the groove of the cam-wheel at its rear end, the transversely-movable slide-operating bar, the pivoted seed-slides L, operated by said "bar, the pivoted levers N in the seedspouts and operated'by said bar, the rack O "on the bar, and the vertical pivoted marker 0, having teeth on its, upper end engaging said rack, substantially as set forth.
