SEEDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 284,060, dated August 28, 15333.

Application filed July 14, 182.

To all whom it mayconcerlt.-

Be it known that I, SILAs G. RANDALL, of Greene, in the county of Chenango and State of New York, have invented certain new and useful Improvements in Seeding-Machines, of which the following is a specification.

The primary objects of my invention are First. Toprovide a practical and efficient machine in which the ordinary drill-teeth or grain-spouts are dispensed with and the grain pressed into the earth by rotating wheels. By such a construction any rubbish or weeds encountered by the machine in its traverse over the fields will be run down and cut up by the grain-wheels, andcannot accumulate upon the seeding parts of the machine.

Second. To provide a seed-sowing conduit or conveyor in which the downwardly-moving face or periphery of a rotating seed-wheel forms one of the walls..

rlhird. To provide an improved force-feed, which, while feeding the seed positively, keeps it under tension by means of a cheek and de livers it to the grain-wheels in the most advantageous manner.

Fourth. To provide an organization by which the weight of the machine may be thrown more or less upon the grain-wheels 'which press the seed into the earth.

My invention therefore consists in certain improved organizations for accomplishing` the above objects, and in other and further improvements, which will be fully set forth hereinafter.

ln the accompanying drawings, Figure l is a vertical section; Fig. 2, a rear elevation; Fig. 3, a detail sectional view on a larger scale,

' showing the seed-feedingmechanism; and Fig.

et is a detail plan view, partly in'section, show ing the driving-wheel and the adjoining grainwheel and its connections.

Two main carrying and supporting wheels, A A, turn loosely upon the main axle. On each end of the axle, just within the supporting-wheels, frame-pieces lB B, preferably cast, are mounted, and project toward the front of the machine. These side pieces are united at their forward ends by a tie-rod, B, and by crossbeams C O, which t into sockets or between flanges b, cast on the frame-pieces, as shown more especially in Fig. 4. The cross-beams C C form the sides of the lower portion of the seed-box D, and the upper and enlarged portion of the seed-box is supported upon them, the parts being bolted together and secured by suitable straps or angle-irons, c. rI he angular tongue-casting E, vwhich is formed with a flange or web, c, to give it propel' strength, passes between the upper and lower portions of the seed-boX, and is securely bolted thereto, as clearly shown in Fig. 1. The rear end of the tongue abuts against the side of the seed-box, and is bolted to the tongue-casting. A seat-supporting beam', F, rests in steps or notches formed in the upper edges of the seedbox, and projects rearwardly over the machine. This beam is securely held by bolts f, which pass through the beam and tongue-casting, as seen in Fig. l, the bolts also serving to bind the parts firmly together. The mere details of the construction and fastenings of the seed-box, tongue, and seat-supporting beam will be readily understood by those familiar with such matters. A series of tubes, d, are placed in the rear cross-beam, G. rlhe tops of the portions of the tubes within the seed-box are cut off, so as to form open-faced tubes at d, while the ends projecting beyond the crossbeam are ball-shaped to form bearings and points of connection for the grain-tubes G and give a 'lieXing connection between them. These grain-tubes are formed or carried in frames or castings H, in the open or forked ends H of which the grain-wheels I have their bearings, and terminate at the inner ends of the forks or openings in theframes or castings opposite the faces of the grain-wheels, as clearly illustrated in Fig. 3. rlfhe upper end of each frame or casting is formed with trunnions It', which have suitable bearings in socket or 'journal pieces K, which are secured to the rear crossbeam, C, by bolts 7c, as illustrated in Fig; 4, the outer trunnion of each casting next to the driving-wheels having its bearing in a socket, 7c', formed in the frame-piece B. Vth the castings in place, the ball-bearings d2 of the tubes d iit snugly in the mouths of the graintubes G, forming a flexing joint. It will thus be seen A trically with the face of the wheel, as

that the castings H, with the grainwheels, may rise and fall freely on their bearings lh' and d2 without interfering with the feed of' the grain. The grain-wheels are preferably formed with ilanges t' on each side, so as to give the wheels a comparatively deep groove' in their periphcries. Each casting H is formed with a downwardly-projecting guide, H2, which eX- tends from the seed-tube G into the groove in the periphery of the grain-Wheel in proper proximity to the bottom of the groove, and then for a suitable distance is curved concenclearly illustrated in Fig. 3. On each side of this guide-piece are vertical flanges H3, which ter minate opposite the edges of the iianges fi on the seed at a proper depth.

the grain-wheels, and in close proximity thereto. This construction provides va trough or guide for the grain fromthe tube G into the grooved face or periphery of the grain-wheel, so that the grain will be conveyed and delivered near the bottom ofthe wheel. It will be ,observed that the face of the wheel forms a portion or wall kof this conveyer. Further than this, it should be noted that the periphery or face of the wheel is constantly moving downward toward the earth as themachine travels over the field. 1 This moving wall of the conveyer insures a more free and perfect feed of the seed than could otherwise be obtained, and permits the conveyer to be/made of smaller sections, and also enables me to use a grain-wheel with a very narrow tread, so

that the available weight in a machine of this press the graincharacter will be sufiicient to wheels firmly into the earth, so as to deposit This pressure on the wheels may be varied to suit the condition of the soil and any other attendant conditions or circumstances. y

So far as I am aware, I am the rst to produce a seeder operating in the manner above set forth. Of course the details of the construction may be varied without departing from the essence of the invention.

- A scraper or cleaner, '52, on the end of each of the frames or castings fits snugly in the groove in the grain-wheel and keeps it free of' earth and clogging matter. The portion of the guide H2 which is curved to conform to the bottom of the groove or face of 4the wheel is preferably within the flanges z' of the wheel, so that in traversing the -field any rubbish or dbris met by the machine will be run down by the flanges, and will not accumulate upon the guide H2. At the end of the opening of the grain-tube G opposite the face of the grainwheel a lid or clapper, G', is hinged, and is normally kept closed under tension, preferably by a spring, g. This lid may be permanently and rigidly closed by means of a locking-pinv which passes through apertures g' in the guide-flanges H3. Part of the grain-tubes may thus be securely locked when the machine is being used to sow narrow strips and irregular spaces in finishing off.

In the bottom of the grain-box a rock-shaft,

L, has its bearings. This shaft carries on its .the tubes d to the grain tubes and wheels. The

rock-shaft L is actuated in the following manner: At 011e end an upright rod, M, is secured to the shaft L, and is rocked back and forth by means of a pitnian, M', driven by a crankwheel, m, operated by a'pinion, m', which is rotated by an internally-geared ring, M2, on one of the carrying-wheels. In order to provide for varying ranges of motion or different thrusts of the plungers Z, the pitman M' may be adjusted vertically on the upright rod M by means of its connecting-block N and vsetscrew, which will be clearly understood upon reference to Figs. and 3. The crank-wheel m and pinion m' are carried by and have their lbearings on a vertical bar, O, which rocks on a pivot on the frame-piece B. The upper portion of the bar O is reduced, and is provided with a sliding collar, O'. This collar has a lug or catch, o, which projects somewhat to one side and engages in notches o'in the curved arm O2 ofthe frame-piece B. The gear-wheel may be therefore thrown into or out of gear with the driving-ring M2 by raising the collar and throwing the bar O either forward or back, the bar being locked in either position by the engagement of the lug 0 in a notch, o'.

The seat F' is provided with rollers f3, so that it may travel back and forth on the seatsupporting beam F. The foot-rest P is pivoted just beneath the beam F in two lugs, f', depending from the seat, Aand' is prolonged somewhat beyond its pivot, soas to form a clamping or locking jaw, p, by which the seat will be locked in any desired position. This is clearly illustrated in Fig.`.l, where it will be seen that by releasing the pressure on'the footesupport the seat may be pushed back and forth onthe beam F, and may readily be locked in any desired position thereon by pressing upon the foot-rest. Blocks f2 on the under face of the seat-supporting beam limit the movement of the seat and prevent its accidental displacement. By means of this travcling seat the driver may move himself back and forth on the machine to reach the various parts, and may place his weight at any desired point thereon.

A rock-shaft, Q, is pivoted between the front ends of the frame-pieces B. cured on the under face of the rock-shaft, eX- tendbackward and engage in loops q on the under faces of the castings H. A lever, R, provided with a detent, is secured upon one end of the rock-shaft, and is heldin any desiredposition by a rack, R'. The driver, by operating this lever, may depress or elevate the springs Q', and thereby throw more or less weight upon the grain-wheels, as may be de- IOO IIO

sircd. As above mentioned, this operation is desirable to meet varying conditions under which the machine works. Under certain circumstances more weight will obviouslybe rei quired at one time than at another to place the seed at the proper depth.

Many of the details of the construction and organization above described may be changed without departing from the principles of my invention. For instance, instead of having a spring arm or lever extend from the rock-shaft Q to each grain-wheel frame or casting, the gang of grain-wheels might be connected by a cross-bar or frame, and that bar be connected with the rock-shaft. Other changes will of course readily be suggested to those skilled in this class of machines.

In operation the seed from the box is forced or pumped into the tubes d, through the tubes G and guides I-Il into the grooves in the grainwheels, is deposited under the tread of the wheels, and is by them pressed firmly into the soil. At each stroke of the plungers in the seed-box the seed, being positively driven through the tubes, as above described, over-` comes for the moment the tension of the checkvalves or clappers, which, however, promptly cut off the supply of seed when the thrust of the plungers has ceased, andthe seed is therefore deposited in distinct quantities by distinct series of impulses. By this arrangement the seed is deposited in the most advantageous manner. By adjusting` the pitman-coupling N on the vertical shaft M the rapidity and length of the strokes of the plungers may be increased to such a degree as to deliver the seed in a practically-'continuous stream, or may be so decreased as to deliver the seed in a series of distinct quantities. As the machine moves over the field each grain-wheel acts independently to deposit the seed in the soil and firmly press it therein, and each wheel is free to rise independently against the tension of a spring. My improved seed-feeding mechanism insures the regular and uniform feed of the seed, no matter at what angle the machine may be placed in traversing over undulations or up and down inclinations on the surface of the ground. a

I am aware that in the vpatent of Hiram Moore, No. 31,819, granted March 26, 1861, a machine is shown'in which, by means of a le ver-and-link connection, more or less weight can be thrown upon cutting blades or edges on the ends of a series of grain-tubes. I am also aware that in the patent of J. D. Smith, No. 35,713, granted June 24, 1362, a series of cut` ters carried on the ends of cutter-arms are normally pressed into the earth by means of aseries of springs, which serve to connect the cutter-beams with the frame. I therefore make no claingi to such organizations. w

I am aware that the/patent of Willis, No. 7 ,0114, of January 22, 1850, shows a seed-plant- V er in which a flanged grain-wheel is employed in connection with a shield which directs theV seed into the flanged face of the wheel at a point at or about the horizontal plane of the aXis of the wheel, and with a plow which pre cedes the wheel.
