DISTRIBUTER FOR SE E DS AND FERTILIZERS.

SPECIFICATION forming part of Letters Patent No. 603,476, dated May 3, 1898.

Application filed May 10, 1897.

' Moorestown, Burlington county, State of New Jersey, have invented certainnew and useful Improvements in Distributers for Seeds and Fertilizers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain improvements in that class of machines employed to distribute seeds, fertilizers, &c. in a continuous stream along a furrow or row or in predetermined quantities in hills, and has for its object to provide a machine of this character in which the amount or quantity of seed or fertilizer to be dropped may be regulated to anicety.

A further object of my invention is to provide for the ready and accurate adjustment of the hopper discharge-mouth to regulate the quantity of seed discharged.

A still further object of my invention is to provide for the adjustment of the intervals of opening of the hopper, so that in hill sowing the seed can be dropped in hills at varying distances from each other.

A still further object of my invention is to provide for the automatic and instantaneous disconnection of the seed-discharging mechanism from its actuating devices when desired.

Further objects ofmy invention are to provide an improved form of index and adjusting'device which maybe used for both drill and hill sowing, and generally to improve, simplify, and cheapen the construction of the device, as more fully set forth hereinafter.

In'the accompanying drawings, Figure 1 is an elevation of a seedor fertilizer distributor constructed in accordance with my invention.

Fig. 2 is a similar view showing the position which the partsassume when the rear of the machine is elevated from the ground and illustrating the automatic disconnection of the shutter-actuating mechanism. Fig. 3 is a sectional elevation illustrating the principal parts of the structure. Fig. 4 is a view similar to 3, illustrating some of the parts in v a differentposition.

i is a view similar to Fig. 6, illustrating one of the shutter-actuating pins in a different position. Figs. 8 and 9 are inverted views of a portion of the hopper and the shutter discharge. in the closed and open position, respectively. Fig. 10 and 11 are views of the opposite faces of the adj usting-index by which the area of the hopper discharge-mouth is regulated. Fig. 12 is a sectional elevation, on an enlarged scale, on the line 12 12, Fig. 1. Fig. 13 illustrates detached perspective views of the devices shown in Fig. 12. Fig. 14 is a detached perspective view of the seed-discharge shutter; and Fig. 15 is a sectional plan view, on an enlarged scale, on the line 15 15, Fig. 5.

Referring'to the drawings, A represents a seed-hopper, preferably rectangular in form and provided with a hinged or removable lid a, which may be opened for the introduction of the seed. The bottom section A of the hopper is preferably formed of cast metal and is gr'aduallytapered toward its lower end, forming toward the front an opening, closed on each side by arms b, which are connected at their lower ends by an integral cross-piece b, angular in form and so arranged that in connection with the lowermost edge of the operating shutter it will form a diamond opening. These side pieces I) are segmental in form and on theouter face of each is a rib 19*, forming a guide for a cast-metal box 0, which embraces and entirely surrounds both side pieces and is secured to and forms a part of the discharge-shutter. To the upper portion 0 of the box 0 is secured a curved metallic strip 0', which extends from side to side of the lower portion of the hopper and prevents at alltimes the escape of seed from the rear of the hopper, while at the same time during the reciprocation of the shutter it enters the hopper and acts as a stirring device to agitate the seeds and insure the constant feed of the latter into the discharge-channel of the hopper. Three sides of this dischargechannel are formed by the stationary side pieces I) and the plate 0, while the opposite side is formed by the shutter-piece proper, which is also in the form of a curved metallic strip 0 secured to the lower portion a of the casting O, and at its lower end has a V-shaped notch or slot 0 which coacts with the angular bar I) to form the previously-mentioned diamond-shaped discharge-openin g. The shutter c will at all times prevent the escape of seed from the hopper except when it is so moved as to form, in connection with the cross-bar Z), a discharge-opening through which the seed may fall from the discharging-channel,while its upper end, also entering the hopper, will act as a stirrer and tend to keep the seed from clogging or packing.

Secured to or formed integral with the casting O is an arm or finger O, which projects into the path of a series of studs on the driving-wheel and is actuated thereby in a man ner described hereinafter. The lower portion of the hopper A is provided with a segmentally-slotted guide (I, which is embraced by the casting of which the box O and finger O form part, and in this casting is a pin d, extending transversely through the slot, the pin governing the lowermost position which the shutter may assume, while the guide 61 acts in connection with the other portions of the hopper to form the guide for the movement of the shutter. As a modification of this construction the number of guides may be lessened by providing the shutter structure with arms pivoted to the hopper or to the frame in such manner that the same or substantially the same movement on a curved line would be obtained.

On opposite sides of the portion A of the hopperare formed pivot-lugs e, through which and through the frame of the machine passes a transverse pivot-bolt E.

The frame is in two sections F F, the portion F being that to which the hopper is pivoted and comprising opposite curved side bars f, connected at the front by a cross-bar f and at the upper rear end by a cross-bar f from the central portion of which extends a curved finger f The side bars f are formed integral with dowm'ardly-curved side bars f which carry and are integral with a guidingbox f extending close to the surface of the ground, so as to guide the seed and prevent its being scattered, as by the wind. Immediately in front of the guide-box f is a front bar f for the reception of a removable plowpoint G, which is held in place by means of a bolt 9, passing through a slot 9' in said bar, and is adjustable vertically thereon, so that the plow-point may make a furrow of greater or less depth. The rear of the plow-point is hollow, and within the space thus formed fits an inclined plate f which forms an integral part of the section F of the frame.

The portion F of the frame comprises two separate arms h, each provided near the forward end with an opening for the passage of a bolt 2', forming a shaft or support for the driving-wheel I. On the outer rear faces of each arm are integral plates h, having segmental slots 7&2 for the passage of the securing-boltsj of the handles J, and at the lower end of the plates 7t is a projecting rest 71. having a rib h, which fitslinto a slot j, cut in the end of the handle, the whole forming a step or support against which the lower end of the handle fits and avoids the necessity of a double set of securing-bolts.

The means for connecting and for adjusting the relative positions of the sections of the frame are more clearly illustrated in Figs. 12 and 13. The inner face of each side of the frame F is provided with a rib or ribs 70, spaced by a square opening for the passage of the securing-bolt K, and immediately above and below this opening are inwardlyprojecting bosses k which extend into a vertical slot 70 formed in the lower rear face of each of the arms 7L. On the inner face of each arm are formed three or more slots l, into which may enter ribs b, so that the relative vertical positions of the front and rear sections of the frame may be altered to accommodate the character of the work to be carried on, the ribs 70 entering the slots I and the bosses 70 entering the slots 70 and forming, when the bolt K is tightened, a rigid structure.

On the bolt t", or on a suitable antifrictionsleeve surrounding the same, is mounted the driving-wheel I, provided with an inwardlyprojecting flange or ring m, in which are formed a series of threaded openings n, shown more clearly in Figs. 6 and 7. To these threaded openings are adapted doubleended stud-bolts m, having a squared central portion m and one end of the bolt being threaded and adapted to the threaded orifice 01, while the opposite end is smooth and projects beyond the face of the wheel in the plane of the finger O of the seed-discharge shutter. The numberof these openings maybe varied at pleasure and they may be placed at equal or varying distances from each other, in accordance with the character of work which the machine is intended to perform or in accordance with the distance of the hills from each other. hen the distance has been determinedsay six, nine, twelve or more inches from each other--the stud-bolts are arranged in the threaded openings at the required distance from each other and the remainder of the bolts not to be used are removed and screwed into the openings 01 from the opposite face of the ring m, so that their projecting smooth ends will be entirely within the periphery of the wheel and will not act upon the finger O.

The mechanism for effecting the adjustment of the area of the seed-discharge opening comprises a cam-plate O, the obverse and reverse sides of which are illustrated in Figs. 10 and 11, respectively. This plate is held by a thumb-screw 0 in the outer end of a yoke 0, formed integral with the casting A of the hopper and surrounding the fingerf of the frame, the edge of the cam -plate bearing against the rear face of the finger f and as the latter forms a part of a stationary frame the turning of the cam-plate on the thumbscrew as an axis will effect the movement of the hopper on its pivot-bolt E, and the seed discharge channel of the hopper is moved at first independently of the movement of the discharge-shutter O andthen with the shutter when a, given point is reached to gain the adjustment for the smaller seeds.

It will be noted that the finger G is provided with a projection 10, which comes into contact with a stop at one end of one of the side bars f ,and when in contact with such stop further downward movement of the shutter is prevented. In gaining the adjustment for seeds of the larger variety, such as beans or peas, the cameplate O is turned until, in the lowering of the seed-channel and the conseplate, the bar b of the seed-channel and the plate 0 of the shutter have assumed the 'closedposition 'sho wn in Fig. 8, and the finger O of the shutter has approached a point about on a line with the axis of the driving-wheel. The rotation of the driving-wheel will bring one of the studs m into contact with the under surface of the finger .O and will raisethe shutterfor a considerabledistance untilthe' bar 2) of the seed-channel and the V- shaped slot 0 of the shutter assume the position illustrated in- Fig. 9, this being'the' largest area of seed-opening which can be afforded'in a machine of the size and character shown, and throughit may simultaneously fall several seeds of comparatively large size.

Toadjust the machine forthe sowing of smaller seeds, the cam-plate is turned until the seed-channel of .the hopper moves forward and upward, and the openingmovement ofthe shutter is thus lessened to permit the passage of only a small variety of' seed, suchas celery or turnip.

The machine is adapted for either sowing in continuous rows or for dropping a fixed quantity of seed in hills at predetermined distances from each other, and to gain the proper adjustment for both classes of work I make the adjusting cam-dial in the manner illustrated in Figs. 10 and ll, on referring to which it will be seen that one side .is marked with the word Drills and the opposite side with r the word Hills, and' each side has upon it the names of seeds that can be sown, and corresponding peripheral notcheswhich when set opposite the finger f adjust the sowing for the'seeds indicated.

When this adjustment for the larger-size seed has finally been accom-- plished, the finger f is at a point opposite the notch in the cam plate marked Beans, which is nearest to the pivot-point of the cam- When the machine is employed for hill sowing, the seed falls intermittently direct from the shutter-opening through the guiding-box f to the ground; but where the sowing must be in a continuous row I provide near the lower end of the guide-box)" a slot 1', through which may be-adjusted an inclined plate R, having atone end a finger r, by which it may be moved into or out of operative position. This'plate is held against the under side of the cover-blade pivot r by the spring riwhich partially winds around the pivot and has its central portion extending under the plate B, so that, it will normally tend to raise the said plate and hold it in position by the frictional contact between the plate, the pivot-pin, and the lower wall of the slot 1". On the under side of the plate R is a-recess r into which the spring fits when the plate is withdrawn to the position shown in Fig. 4, and holds said plate in the inoperative position-during all the time that the machine is employed for hill sowing. When it is desired to adjust the machine for. drill sowing, the plate is pushed forward through the slot 0" into the guide-box until a stop r 1 on the plate comes into contact with the pivot-bolt; The operative position of the plate in drill sowing is illustrated in Fig. I

In the operation of drill sowing the seed dropping at close (six inches) intervals from thehopper will fall through the guide-box until it comes into contact with the inclined plate R, from which it will rebound and ricochet until it finally passes beyond the edge of the plate and falls on the inclined plate f in the hollow portion of the plow G, and from thence againiricochet to the ground. These inclined plates are found in practice to effect a thorough scattering and distribution of the seed, as the discharge against the plate'will take place at varying points throughout its surface, and in some cases portions of the seed falling nearest the rear of the plate will rebound several times and make several contacts before it finally falls to the inclined plate f .while other portions of the seed striking near the forward edge of the plate will almost-immediately pass to the plate f and from thence continually to the ground.

On the rear of the guide-box f are formed integral lugs s for the passage of the pivotbolt W, and 'on this bolt are hung two coverblades S, connected by an integralbar s, which comes into contact with stops 5 formed on the lugs, when the blades are in operative position. These blades are free to move toward the front of the machine, swinging on the pivot-bar when the rear end of the machine is raised from the ground.

Pivoted on the bolt E, at points between the frame :and the pivot-lugs e of the hopper, are two arms T, carrying at their rear end a shaft 15, for thesupport of a roller 2!, having a con-' caved or hollow face which rolls down the ground previously operated upon by the plowpoint and the cover-blades; 'The'arms T are extended forward of the pivot-point in the form of levers t the under surfaces of which bear against stops u, projecting from the frame, and the weight of the frame and its connected parts will normally keep such levers in contact with the stops when the machine is in practical operation.

In wheeling the machine to and from the field of operation, or in moving it from furrow to furrow, or in other places where it is desirable to throw the seed-discharging shutter out of gear, the handles J may be depressed until the driving-wheel is raised from the ground, when the machine may be pushed along on the cover-wheel as a support without sowing.

\Vhen the handles are raised to lift the plow out of the ground, the weight of the coverwheel, acting through the lever 15* will move the hopper on its pivot-bolt until the hopper assumes the position illustrated in Fig. 2, and at the same time the lower wall of the slot in the guidcdwill comeinto contact with the pin (1 of the shutter-finger C and will elevate the latter to a point beyond the line of travel of the studs m, and the machine may be wheeled around on the driving-wheel without danger of accidental discharge of any of the seed.

Various modifications of the structure herein described may be made without departing from the spirit of my iuvention-as, for instance, the overlapping V-shaped ends of the seed-channel and the shutter may be partially curved or maybe perfectly straight in lieu of the V-shape, as described, or the shutter in lieu of being guided on the sides of the feedchannel may be provided with arms pivoted to the pivot-bolt E, or the seed-channel and the discharge-shutter may be arranged on a straight instead of a curved line, as shown.
