CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 434,268, dated August 12, 1890.

Application filed August 22, 1889.

` To all whom it may concern:

' that class Ofcom-planters known as checkrow corn-planters, and has for its object the provision of a planting-machine in which the parts will be compactly arranged and all supported on a single frame, and to provide improved means for raising and lowering said frame in order to regulate the depth to which the plows will enter the ground.

A further object of the invention is to provide an improved hanger or support for the packing-wheels, by the use of which the said wheels will be permitted to turn at an angle to the frame when the machine is rounding a corner, and also allowed to yield readily to anyinequalities of the surface of the ground.

A further object of the invention is to provide an improved mechanism for dropping the corn; and with' these several objects in view the invention consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a planter provided with my improvements. Fig. 2 is a longitudinal section. Fig. 3 is a longitudinal section. Fig. 4 is a detail view of the anchor for the checkwire. Fig 5 is a detail perspective view of the marker. Fig. 6 is a detail sectional view. Fig. -7 is a detail perspective View of a portion of the axle, the frame, and the devices whereby the frame is supported on the axle. Fig. 8 is a detail plan view of the reciprocating bar which operates the seed-slides. Fig. 9 is a longitudinal section on the line z z of Fig.

'8. Fig. 10 is a front elevation of the planter.

Fig. 1l is a transverse section.

The axle A is angular in cross-section, and the carrying-wheels B are mounted on the ends of the axle in the usual or any preferred manner. Near its ends the axle is provided 011 its opposite sides with the grooved blocks C, which serve as guides to cause the main frame to move in a true vertical plane. The

'frame D is substantially rectangular in form and is composed of the side bars E, the cross- Serial No. 321,676. (No model.)

bars F, and the tongue G, secured upon the cross-bars at the center of the same and projecting forward a considerable distance to permit the attachment of the draft-applying devices. The side bars E, it will be observed upon reference to Fig. l, are arranged in pairs, the members of each pair converging 'slightly toward their front ends, as clearly shown. To the inner sides of the inner side bars E, I secure the brackets H, which are provided with the vertical slots I and the anges or ribs J along the side edges or walls of the said slots. The ends of the axle pass through the slots I, and the grooves of the blocks C are engaged bythe flanges J, as shown most clearly in Fig. 7. The axle is thus prevented'lfrom moving endwise through the brackets, while the frame is allowed to have the necessary vertical movement to secure the desired adjust-ment. The brackets are provided at their upper ends with the horizontal arms K, having longitudinal slots L', and the said arms bear against the inner sides of the side bars E and are secured to the said side bars by the set-screws M, inserted through the slots L into the side bars, as shown in Fig. 7. The bracket can thus be adj usted longitudinally on the side bars, so that the frame will be balanced upon the axle. On the upper side of the axle and adjacent to the brackets Il, I secure the posts or standards N, to the upper ends of which I pivot the levers O, which have their outer. ends pivotally secured to the-upper ends of the brackets H. The inner ends of these levers are attached to a vertically-movable bar P,Which is mounted in the tongue and is provided on its rear side with notches Q. On the under side of the tongue I mount a sliding latch R, which is adapted to engage the notches Q, and thereby prevent movement of the said bar P, and consequently hold the frame in its raised or lowered position. This latch is disengaged from the bar P by a lever S, which isvpivoted within the tongue at a point in advance of the drivers seatand has its lower end playing in an opening in the latch. v

The inner ends of the levers O 'are provided with the links T, having inwardly-projecting horizontal pivot-pins U at their upper ends, and these rollers are engaged by the slots V in the front end of the levers W,

IDO

which arefulcrumed on the sides of the tonguenand have vertical arms depending below thetoirguie.-v In rear of these levers YV, I

fulcruin upon the sides of the tongue the angledevers X, which are provided at their upper ends with the lateral arms Y, adapted to serve as pedals, so that the lever may be operated by the drivers foot, and the lower ends of the levers X are connected with the lower ends of the levers WV by the links Y', as shown most clearly in Fig. 2.

The packing-wheels Z are journalcd in the lower ends of the slotted brackets a, which have their upper ends swiveled to the hangers b, the said hangers b being pivoted to the opposing sides of the side bars E. The brackets a are provided in the rear edges at theirupper ends with the -notches c, and these notches are engaged by the teeth or lugs d, depending from the lower ends-ot the hangers l). By this construction when the inachine is being turned the tooth or lug (l serves as a pivot on which the bracket a will swing, and when the machine is being drawn forward the said tooth or lug will impinge against the front end of the notch c, so as to draw the same forward. The hangers being pivoted at their upper ends to the side bars of the trame, they will vibrate readily as the machine passes over any irregularity or unevenness in the surface of the ground, and consequently allow the packer-wheels to run over the ground without putting undue strain on their supports. i

The hanger is prevented from swinging too far downward by means of the curved arms e, which are formed integral with the said hangers and extend upward and rearward therefrom and are provided with the longitudinal slots f, which are engaged by the transverse pins g, as clearly shown in Fig. 3. The hangers are provided on their front sides with the cross-bars h, and in the said cl'oss-bars I mount the rods i, having the eyes 7' at their rear ends and provided with the nuts k in advance of the said eyes. Aspring Z is coiled around this rod between the crossbar h and the nut 7.: and bears'against the cross-bar 71, so as to press the same normally forward, and thereby force the hanger downward, and consequently hold the packerwheel to its work. In the rear cross-barI), I mount the bolt m, having the eye n at its front end engaging the eyej, as shown, and this bolt is provided with a nut 0, by means of which it is secured in the cross-bar. The rod fis thus firmly supported and at the saine time allowed to swing freely from side to side as the niachine is carried around a corner.

The hoppers or seed-boxes p are secured on the frame in advance of the axle, and the seed-spouts or planting-tubes o' are secured to the frame directly beneath the hoppers and lead downward therefrom to the ground. I'Vithin each of the sccd-spouts or plantingtubes r, I provide a flirt-valve s, which is provided at its upper end with a cranlrarm t, en-

gaged by an eye or loop u on the side of the transverse reciprocating bar fu, so that the seed within the tube will be prevented from accumulating therein, as will be readily understood. This reciprocating bar 'u is mounted on the upper side of the tongue and the side bars E and is provided at about its center with the eye w, engaged by a pin at the lower end of a vertical roekshatt y, which is mounted on the tongue and provided at its upper end with the arms c, as shown. This rock-shaft is operated by the rotary drivingshaft 2 and is prevented from being forced forward by the blows of the said shaft bythe spring 3, which is secured on the front crossbar of the frame and bears against the vertical rock-shaft.

On the upper side of the frame, at the ends of the same, I erect the standards 4, upon which I secure the adjustable brackets 5, and the driving-shaft- 2 is jonrnaled in the said brackets 5. The said driving-shaft is provided near its center with the radial striking-pins on canrarms 6, around which I arrange anti-friction sleeves or rollers 7, and the said striking-pins are adapted to come into contact with the arms .e of the rock-shaft y, and thereby operate the said-shaft. At the ends of the driving-shaft 2, I secure the wheels 8, which consist of a pair of plates having the radial arms 9, and the rollers l0, j ourna-led in and extending between the said arms. The check-row wire passes between the arms 0 and over the rollers l0, and at the ends of the brackets 5, I provide the usual pulleys Il for guiding the check-row wire to the wheels.

The seed-disk l2 is mounted on a vertical journal 13 within the hopper and is adapted to rotate therein, and on its under side it is provided with depending teeth or lugs lll, as clearly shown. The reciprocating bar o is provided at its ends with the forks l5, and the arms or tines of the said forks are provided at their ends with the longitudinal slots or recesses 1G, in which I pivot the pawls 17, which are adapted to engage the lugs or teeth 14 on the under side of the seed-disk. These pawls are arranged reversely to each other in the arms of the forks, so as to engage diametrically-opposite lugs on the seed-disk, and they are normally pressed upward into the path of the said lugs by the springs l8,which are secured in the slots or recesses 1G and bear on the under sides of the pawls.

To the front side of the seed-spout or planting-tube, at the lower end of the same, I sccure the shovel 19, which is adapted to take into the ground and forms a furrow therein as the machine is drawn over the ield. On the sides ot the seed-spouts I provide the pins 20, and these pins are engaged by the vertical slots 2l in the front ends ot the eovercrs 22, which consist of elongated plates extending rearward from the sced-spouts and are.

adapted to throw the loose dirt into the furrow over the seed. These coverers are pre- IIO 4.345268 v y i -to be used in connection with my improved machine, so as to indicate the line of the next I furrow while the seed is being-planted in one furrow. This marker consists of a rod or bar 24C, having one end pivoted toa bracket25, secured on the rear cross-bar of the frame,

and having a runner 26 secured to its other end and adaptedto make a depression in the ground as the machine is drawn along. A

chain 27 is secured to the rod 2l and the end of the rod eng'aged over a hook 28, secured to the rear cross-bar of the frame at the end of thc same, so as to hold the marker to its work. A p

In Fig. 4 I have illustrated my improved anchor-post for the check-row wire. This iinproved anchor consists of a cylindrical rod or bar 20, which is journaled in a suitable base located in the ground at one side or end of the field in a vertical position. Upon this rod I mount the triangular frame 30, which is adapted to turn horizontally and slide vertically on the said rod, so as to permit the check-row wire to be carried off in any desired direction, and within the'fraine 30 I arrange the hook 31, around the shank of which a spring 2 is coiled, the said spring bearing between a bar 33 of the frame and a nut or shoulder 3a on the hook. This spring preserves the tension of the check -row wire, while at the same time it allows the hook to yield to any sudden strain put on the wire, and consequently prevents the breaking of the Wire.

In practice the hoppers or seed-boxes are filled with seed and the machine is then drawn over the ground in the usual manner. As the machine is drawn forward,the check-row wire will rotate the wheels 8 in the ordinary manner, and thereby operate the driving-shaft 2. As the said shaft is rotated, the striker-pins 6 thereon will be brought into contact with the arms ,e of the vertical rock-shaft y, and the transverse bar u will thus be reciprocated. As this bar o slides back and forth, the pawls carried thereby will engage the lugs on the under sides of theseed-disks, and consequently rotate the saine. `When the bar moves in one direction, the rear pawl at one end o f the bar i; will rotate the seed-slide, While the front pawl at that end will slip past the lugs on the said slide. At the opposite end of the bar the front pawl will engage the disk and the rear pawl slip on the same, so that both seed-disks will be operated, and on the reverse movement of the bar the pawls which wer'e formerly disengaged will be brought into play and the disks thereby rotated. Seed Will thus be planted from both hoppers at each stroke of the bar. As the bar is vibrated, furthermore, the Hirt-valve will be oscillated in the seed spouts and the seed prevented from accumulating therein. The shovels on the front side of the seed-spout's form furrows, 'and 'theseed is discharged directly into these f urrows, while the covering-plates, being drawn along directly in rear of the seedsspouts, will throw the dirt back into the furrow over the seeds, and the dirt will be packed down by the wheels Z, which run directly in rear of the covering-plates.

From the foregoing description, taken in connection with the accom panying` drawings, it will be seen that I have provided a very eiiicient. corn-planter in which the several parts are all supported upon a single frame, so that by raising or lowering the said frame the depth to which the several parts will enter the ground or the force with which they will press on the ground will be simultaneously and rapidly regulated. If it be desired to plant the seed deep, the levers O are vibrated so as to lower the frame, thereby simultaneously lowering the seedspouts and devices carried thereby and the packingwheels. The levers O may be operated either by vibrating the angle-levers X by the foot or by operating the vertical bar P, and in either event the desired adjustment will be easily and quickly eected. t
