The forward end of the upper bar B is produced beyond the end of the lower bar B to form a hinge-socket b for a pin, and is then returned rearwardly below the lower member of the side bar, to which it is secured by the end a of the brace A The trunnion A is extended above and below to form seats for the two elements of the side bar, the bolt a fastening them thereon. Side flanges a prevent side motion and locate the position of the parts. A lever-arc O is carried upon the tube A midway in its length and is secured in position by a bolt 0, passing through its hub and through the tube. The are is provided with a trunnion c, as shown most clearly in Fig. 19, to receive the eye a of the brace A also held by the bolt (3. A seat-support A extends upwardly and rearwardly from the are, forming a member of a tripod, which is completed by the double brace A mounted upon the rear ends of the side bars B and held between its members B and B. The bolts 1) b which bind these parts together, also secure the ends of the brace. The extended end of the seat-support,

. which preferably returns upon itself, Fig. 26, is

a portion a and increases its strength and carrying capacity. The brace A of V form, is turned upwardly at right angles at each end to form a threaded portion a, which passes through and secures the members of the side bars together and closes the hinge-sockets 19 At its center a loop or eye a serves to attach it to the arc, as before described, and to thus rigidly tie the brace and parts of the entire wheel-frame together. The scraper-bar-D is also of tubing loosely confined in the end bearings b of the side bars and carries upon each end a scraper E, which serves to clear the planter wheels from accumulations. These scrapers are in two parts,Figs 27 and 28-21. body-piece e, of any satisfactory contour to suit the surface of the wheel, and a clamping portion e to secure it to the bar.

The one casting has projecting lugs 6 adapted to receive complementary lugs e, extending from the other casting, and to form therewith a hinging connection. Abolt passes through the apertures e and c and firmly clamps the scraperin position upon the bar. By this arrangement of parts the scrapers may be accurately adjusted to the surface of the wheels and an even contact maintained therewith not obtainable were they pinned fixedly to the bar. One end of the brace A maybe extended beyond one of the side bars and be notched at a, Fig. 30, to receive the flange f of an arm F, pinned upon the scraper-bar D as ameans of its rotation. The bar is thus locked against end motion and maintains the lateral position of the scrapers. Astop 1 pre vents undue rotation of the bar and holds the scrapers a proper distance from the surface of the wheel when they are not in use, and yet in such proximity that they maybe readily applied whenever it is desired to do so.

be described.

The lever G is preferably constructed of two parts, the one G having the operatingarm g extending upwardly and provided with the usual latching devices and the other G riveted or otherwise secured to it to form a bifurcated lever, between the parts of which the are C is received. Both parts have rearwardly-projecting foot-arms g and foot-rests g and also forwardlyextending arms 9 which may be provided with a foot-rest similar to that of the rear arms, or, if preferred, may have the rest 9 formed of tubing secured between the ends of the two castings. As will be seen by referring to Figs. 1, 2, and 18, this compound lever is fulcrumed or pivoted directly on the cylindrical axle A and has bearings thereon widely separated, thus obtaining the greatest stability and strength laterally and pivotally, together with the utmost simplicity of parts. The are 10- cates its position and prevents side motion.

In planters it is requisite that great leverage be given the foot-arms to secure ease in the raising and lowering of the runner-frame to regulate the depth of planting. These arms are in the form of a triangle, the base of which is the tube, thus obtaining steadiness of operation. The links connecting the lever to the tongue projecting through the runner-frame are pivoted to it in the apertures g.

By the arrangement of parts described as constituting the wheel-frame great strength and-flexibility are obtained. This flexibility is particularly desirable in the side bars, since they control the position of the runners, and if rigid would prevent them from following, as is necessary, the irregularities of the ground over which they pass. They may be given more or less spring, as is found desirable, by the method shown in Fig. 21, the aperture 12 in the bar B being here shown of such size as to permit play of one bar upon the other. The form of bars shown in Figs. 17 and 21 are found to be very satisfactory and possess sufficiently the qualities of elliptical springs to secure the desired results. It will be observed, also, that the seat, which is supported principally upon the extreme rear ends of the bars, is cushioned by this same spring action. The draft strain delivered to the bars at thehingesockets b is evenly divided and carried to both sides of the strut and delivered 011 both ends of the bolts a a, rendering the strain very equable.

The runner-frame of the planter will now The main beam I, to which the hoppers and the seed-legs are attached, is of angle-steel, and the frontbeam H is of barsteel, arranged as a truss in form somewhat similar to the side bars previously described. Bolts h h fasten these bars together at their ends, and struts H H hold them apart at their middle. The struts have holes h h,

through which to insert a pin to secure the tongue to the frame and to adjust its height to suit the size of the team employed for draft purposes. An aperture Win eachserves for the insertion of the hooked end of abrace I,

the rearward end of which is bent and threaded for attachment in the main beam, the hinge-casting I being secured to the beam by it. The frame is strongly braced by these ties and the draft strain transmitted by them directly from the tongue to the ends of the side bars, Fig. 16, and thence to the wheeltrunnions and sideward to the seed-legs and runners. By this direct distribution of strain it is rendered practicable to construct the beams very light and of but little strength. The main beam serves, essentially, as a strut and the front beam as a means for maintaining the front ends of the runners at their proper lateral distances and to exert downward pressure in forcing them into ground. The tongue of the planter is carried to the rearward from the strut H through strap '5,

Fig. 1, on the main beam and to a point below the front end of the lever-arms g, to which it is attached by connection-bars g Fig. 14.

The drop mechanism will now be described. A foundation-plate J rests directly upon the beam I, to which it is secured by the clip projectionsj, Figs. 3, 9, and 10. A bolt vJ fastens it firmly at the rear to the leg K, through which the seed is dropped to earth. The front of the plate is provided with hinge-lugs j, which register with corresponding lugs Z- on the bottom casting L of the hopper and serve as a pivotal point for the swinging of the entire hopper attached thereto into an open position, as indicated in Figs. 1 and 3.

When thus open the drop mechanism is exposed to view for repairing, cleaning, and for the exchange of the drop-plate for others of different-sized apertures. A spring j locks the hopper when closed. The bottom casting L has a central cylindrical opening Z, in which rotates the-drop-plate M, pivoted on a trunnion l projecting from the covering-lug L of the casting L. This plate M when the hopper is closed receives the corn in its cups m and carries it under the cut-off N, where it is dropped into leg K and thence to ground. By making these cups open and tapering toward the periphery of the disk and providing a recess Z in the cylindrical walls in which the disk revolves at the point where the contents of the cup are to be dropped the compression due to forcing the grain into the .cups is relieved and the grain is dropped out with great certainty. It is found that when the cups are cylindrical and closed on all sides clogging is of frequent occurrence and the consequent missing of hill after hill pos sible.

The cylindrical opening Z of t-he'castingsL is closed at the bottom by the pivoted plate L, upon which the drop-plate M rests and revolves. This plate is provided with an aperture 1*, through which the grain is dropped when a seed-cup registers therewith. be readily understood that when the plate L is closed the hopper may be opened and It will shut without the loss of any grain therefrom and that a very ready means for changing drop-plates without removing the grain from the hopperis obtained.

The drop-plate M is provided with lugs m, which,when the hopper is closed, are engaged by lugs 0 on the pawl-wheel 0, operating through a central opening Z in the supplementary plate, and the plate thus given motion. The pawl-wheel rests upon and within the foundation-plate J and is pivoted on a trunnion 3' projecting therefrom. A slide P is arranged to seat and be reciprocated in recessesj in the foundation-plate J and has pawls R, adapted to give motion to the pawlwheel in the usual manner. These pawls are pivoted on trunnions P, having on their outer end a lug p, projecting beyond their bearing-surface in such form that the pawl having a-corresponding recess 4 is permitted to pass over itwhen the free end is held above its normal position, but to be retained by it when in operative position. The slide P is provided with lugs 19 so placed that the lugs 0 upon the pawl-wheel engage with them at the end of each reciprocation and lock the wheel from further movement between it and the operating-pawl. This is for the purpose of maintaining the registry of the seed-cups with the aperture Z in the plate L until the grain has time to drop.

A convenient meansfor attaching the reciprocating connection-bar P to the slide P is shown in Fig. 3. The bar is received below a portion of the slide 19 which prevents it rising from its place when once seated upon thepin 19 The slide P is provided with a wing portion 19 Figs. 9, l0, and 11, which has motion below the plate J at the opening 9' and serves to oscillate the foot-valve S. The wing is so proportioned as to only permit the passage of the grain dropped when the footvalve is nearly at the end of an oscillation. Scattering of grain is thus prevented. The slide P is locked in its seat by the wing proj ecting below the beam-plate, but may be conveniently removed by bringing it to register with the aperture f and lifting first the opposite side from the recess in which it slides. The valve S is of spring-steel pivoted on a bolt T midway in the lengthof the leg. The travel given the top of the valve is somewhat in excess of what is required for its foot to traverse the space between the walls of the chamber in which it moves, a slight pressure against the wall at each end of the stroke being the result. This pressure serves to insure a perfect closing of the valve and the retention of the grain by it. It also allows the slide to obtain full headway before it releases the grain, and then affords a quick release, which prevents a scattering of the grain.

Other points of advantage are that the slide is brought to rest at each end of its stroke without jar and that it cannot-bebroken by obstructions forcing themselves into the leg. The aperture through which the pivoting-bolt '1 passes is made by forcing the portions 3 s downwardly and the portion 5 upwardly to form a cylindrical bearing.

To prevent clogging of grain, the lifting of the chiselof the cut-off unnecessarily, and the possibility of grain catching under its corners, a narrowed way U is formed by abutmentwalls to and u to conduct the grain in a narrowed stream to it. Achisel N, pivoted on trunnions oz, integral with it, clears off the surplus grain from the cups of the drop-plates. These trunnions are seated in bearings in the plate L on or about the plane of cut-off, a smoother operation being obtained by this arrangement than by that in which the pivotal point is above the plane of cut-off. The cap casting N", which covers the cut-off chisel and its spring, is provided with recesses a, into which the trunnions of the cut-off are received and held, a single bolt a serving to secure all the parts together.

Referring to Figs; 10, 12, and 13, IV is the cover of the hopper, and W a metallic baror spring secured to it on its under side. This spring is adapted to engage with lugs 20, pro jecting from the casting, when the cover is seated between the guide-lugs w and moved forward. The lugs 10 serve as stops, and the cover when in the position indicated in Fig. 13 is firmly secured.

Other methods besides that of hinging will be found to be satisfactory for holding the hopper in position and yet allow it to be opened for disclosing the drop mechanism. It is not desired to narrowly cover this. The important feature of this part of the invention is the location of the drop-plate within or below the bottom plate of the hopper and the use of a supplementary floor-plate which aifords a bottom cover to its seed-cu-ps, which can be readily removed or from which it can be taken, but when in operative position allows the drop-plate to be carried with the bottom plate of the hopper and acts as a floorplate to protect it and the hopper against loss of grain which is contained in the latter at the time. It is further desired in the matter of the side bars of the planter to cover these not only as trusses, but as springs, which have merits over a rigid bar.
