T @ZZ whom, t may concer/t.-

Be it known that I, EUGENE NV. VEST, of Sedalia, in the county of Pettis and State of Missouri, have invented a new and useful Improvement in Seed-Planters, of which the following is a.full, clear, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification.

The primary object of this invention is to provide a seed-planter in which the depth of the furrow or drill shall be controlled by the weight of the machine, and the invention consists of the novel construction and combination of parts hereinafter described and claimed.

In the drawings, Figure lis a perspective view of my seed-planter. Fig. 2 is a side ele- Fig. 3 is a plan view of the same, partly broken away. Fig. 4 is a section on line yy of Fig. 3. Fig. 5 is a section on line wx of Fig. 3, showing a plate for regulating the quantity of drop. Figs. G and 7 are respectively a section and plan view, showing a modication of the dropper. Fig. Sis a detail sectional view, partly broken away. Fig. 9 is a section on line w fw of Fig. 8, and Fig. 10 is a perspective view of the coverer.

In carrying out the primary object of my in vention, as above stated, I provide for the arrangement of the runners or furrw-openers directly under the supporting-axle of the machine, in order that the weight supported by the axle shall be adapted to force the said run'- ners into the ground,while the wheels which carry the aXle shall limit this effect of the weight to prevent sinking the runners into the soil beyond the depth for which they 'may be set. Vith such a construction the depth of the furrow will always be uniform, no matter how uneven the surface of the ground may be, Y since the wheels, which always move `on the surface of the ground, serve as gages for the runners and compel them to move up or down, according to the undulations or unevenness of the ground. The advantages of such a construction are obvious. The entire crop of corn' or other grain will be planted the same depth, producing uniformity of growth, and as the runners are to bemade adjustable, the depth of the planting may be regulated-according to the requirement of each particular kind of grain,without the danger of planting too deep,

Iand thus in some seasons necessitating the re- `planting of whole fields.

Referring to the drawings illustrating this particular part of my invention, A indicates the framework proper; B, the supportingaxle, and C the wheels carrying the axle. Each wheel G is preferably formed of two parallel disks, rims, or fellies, D connected to a single parts D of each wheel is arranged the runner G,which is connected to the two arms of the lever F, and is thus adapted to o'scillatefon the hub E.

i The runner 'G is formed with a tapering body, g, having vertical sides and a Vfshaped bottom in cross-section, as shown in Fig. 9,

and with a long curved arm, g, which is pivoted to the arm 7L of abell-crank, H, connected to a rock-shaft, I, which is journaled on the forward part of frame A. A pivoted bar, J, connecting the arm h of the bell-crank with the armf of the lever F, completes the eonnection of the runner with the upper end of said lever. In the end of the arm j" of the lever F is swiveled a rod, K, which screws into the body g of the runner, and forms the main connection of the runner with the lever. This rod serves by its screw-connection with the runner to adjust and hold the' runner at the desired position for making the furrow. The connection of the arm f/ of the runner with the lever F by means of the bar J is not essential to the operation of the device, since the runner is rigidly connected to the said lever by the rod K; but the bar J adds strength to the connection and gives increased power in lifting the runner by means of the rock-shaft I. This rock-shaft is connected to a hand-lever, L, bya bar, M, and is to be set by means of the rack N, with which a pawl on the lever engages. The lower part of the curved arm gf, at the point g2, where it unites with the body of the runner, is made straight, in order that when the bell-crank is oscillated in the direction of the arrow, Fig. 2, the body and armvof loo the runner may swing rearward out of contact with the ground, the said straight part g2 being then brought into a horizontal Vposition along the surface of the ground.

To connect the runner or furrow-opener with the spout of the hopper, the former is providcd with a chute, O, which is rigidly attached to the rear end of the body of the runner, and forms a sliding joint with the spout. In such case the hoppers P will be supported on a supplemental frame, Q., hinged to the frame A at R, and supported on casters S, as shown in Figs. 2 and 8. Instead of this arrangement, however, I may support thehoppers on the runners by means of the chiites O, and brace them by arms connected to levers F in such 'manner that they shall move with the adjustment of the runners; but where the sliding connection is made by the chute and spout byv making the chute slightly larger than the spout, which is arranged therein, the chute will have sufficient play thereon to accommodate the movement of the runners when the latter are lifted out of the ground. The hoppers are provided with my improved dropper, by which I provide for dropping an exact number of grains of corn in each hill. This dropper consists of a slide, T, or rotary disk T, having a given number of cups, U, each large enough to contain one grain only, and arranged in rows, which rows are adapted to deliver their grains in turn at separate movements of the dropper.

@ver the delivery-openiiig V in the bottom of the hopper, and above the slide or disk, is secured a guard or cut-oif, IV, having openings Y in its sides, which register with the cups U. Inside this guard, which is box-shaped, is arranged opposite to each opening Y a scraper or valve, Z, consisting of an angular plate pivoted at one end near the center ofthe guard, with its center or angle opposite io the opening, and held down in a yielding manner upon the upper surface of the slide or disk by a spring, A, and a weight, B', resting on the spr'in 0'( Suitable partitions are to be arranged in the guard WV, for holding the weights in pcsition. rlhe plates or valves serve to brush off any second or third grain that may be partially held by any of the cups, the angle of the valves and their yielding character preventing any cutting or cracking of the grains. To guide the grains into-the cups the hoppers are provided with longitudinal or circular ribs C,according to the character of the dropper, which ribs have their sides sloping to the cups. These ribs are secured to the hoppers just above the slide or disks of the dropper. Vhen the number of grains planted to a hill is to be lessened, a number of the cups are to be covered by se-V curing a plate over them. There the slidedropper is used, a plate, D', as shown in Fig. 5, is to be bolted to one side of the hopper, with its lower end braced against one of the ribs C. By means of a suitable slot in the plate, it may be adj Listed to cover any number of holes or cups desired. Vhere the rotary dropper is used, as shown in Fig. 6, a disk, E', is to be bolted to the center of the disk, with its edge resting against one ofthe circular ribs. The disk is to be made somewhat convex on top to guide the grain outward to the open cups. Each hopper is to be provided with a series of such plates of different sizes, Ya larger or smaller one being used, according to the number of cups to be left open. In Fig. 7', F indicates the usual means for rotating the dropper.

The coverer G consists of two plates or shares, which are set in an approximately vertical position and connected by a cross-bar, H, arranged near their centers. rlhe forward ends of the plates are pivoted to the ruimer or chiite, as shown in Fig. 2, with the chute arranged between them to convey the grain to the furrow just in the rear of the runner. The plates are to be arranged sufficiently far apart to stride the furrow, and they incline slightly toward each other at the rear, in order that they shall rake the soil inward to the center, forming a continuous inound,which is pressed by the casters following at the rear of the planter.

To hold the coverer down in the` soil at the desired depth, the cross-bar H is provided with an opening, in which a rod, I, connected to the chiite, is loosely arranged, and a spring, J, is arranged on the rod between the bar H and anut, K, screwing on the rod. The spring, the tension of which is regulated by the screw and nut, serves to hold the coverer down in a rm but yielding manner, so that it will pass over obstructions without danger of breakage.

L M are rock-shafts carrying scrapers for the wheels and casters, and N N are treadles for operating the same. O P are seats for the operators.

Vhat I claim isl. The combination, withv the main axle in a seed-planter, of the runners or furrow-openers arranged underneath the said aXle and attached thereto, whereby the weight of the machine shall sink the runners into the ground, and the supportingwheels on said axle shall serve as gages for the runners to regulate the depth of furrow, substantially as specified.

2. rIhe combination, with the main axle in a seed-planter, of the runners or furrow-openers arranged underneath the said aXle, and pivoted on said axle or the hubs of its wheels, and the supporting-wheels formed with two rims each, which stride the runners to serve as gages for the same while the weight of the machine forces the runners into the ground, substantially as speciiied.

3. The combination of the wheels, each formed with two rims secured to a single hub, the levers j ouriialed on the cent al part of the said hubs, and the runners arranged under the aXle, between the rims of the wheels,-and jour- 'naled on a rock-shait at their forward ends, 'and means for connecting the forward and rear ends of the runners to the ends of the said levers, substantially as specified.

4. The combination of the wheels, formed as described, the levers journaled on the central part of the hubs of the wheels and having upper and lower arms, the runners connected to a rock-shaft at their forward ends and arranged to extend back under the hubs, the bars`connecting the rock-shaft with the upper arms of the said levers, and means for operating and controlling the rock-shaft, and the swiveled screw-rods connecting the runners at their rear ends with the lower arms of the said levers, substantially as specified. 4

5. The combination, with the runners formed with chutes for conveying the grain from the hoppers or hopper-spouts tothe furrows, of the cover-ers, each consisting of two approximately-vertical plates or shares connected together and pivoted to the runners or chutes, and the adjusting springs and screws arranged between the chutes and coverers, substantially as specified.

6. The combination, with the hoppers, of the dropper having the seed-cups arranged in rows, the cups of each of which deliver their grains together, the guard made box-shaped, with openings at the sides, and having pivoted angular valves arranged to close said openings, and springs and weights for controlling the valves, substantially as specified.
