AUTOMATIC CHECK-ROW CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 516,177, dated March 13, 1894.

Appli i n filed February 10, 1892- Serial No. 420,960. (No model.)

To aZZ whom it may concern.-

Be it known that I, ABRAHAM ANDERSON, a citizen of the United States, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Check-Bower Corn-Planters, of which the following is specification.

This invention relates generally to check rower corn planters, of that class or type in which the dropping mechanism of the planter is actuated at uniform distances in the travel of the planter, for depositing the seed in check rows, by contact of a forked lever or arm of the check rower rock shaft with tappets located in regular sequence on a check rower line which is laid over the ground adjacent to the path of the planter, and which contact trips or swings the forked lever, and thereby gives a partial rotation in one direction to the rock shaft, a motion in a reverse direction to which is given by a spring or otherwise; and the invention relates especially to improved means for doffing or discharging the check rower line at the ends of rows; to improved means for transmitting to the seedcup wheels intermittent revolutions in one direction, from such oscillating or rocking motion of the rock-shaft; and further specially relates to improvements in the discharge valve at the lower end of the seedtube, and means for operating it; to structural features of the seed-cup wheel, and its gear connection with the rock-shaft; and to other constructions and combinations hereinafter described, and these improvements have for their object the production of an efficient planting machine, andwhich while structurally strong and durable will be effiever, some of these improvements may be used without the others, and in planters differing in class or type, in construction, and in organization from the part of a planter shown by said drawings, and in which the improvements are incorporated.

In said drawings:Figurel is a top plan of the forward part or frame of an ordinary planter, embodying my improvements;'Fig. 2, a perspective of the check rower line doffer, with said line in operating place thereon; Fig. 3, a side elevation of the parts shown at Fig. 2; Fig. 4, a perspective of the parts shown at Fig. 2, with the doffer turned to force the check-rower line out of the pulley; Fig. 5, a perspective of the doffer alone; Fig.

The difierent figures of the drawings are made to different scales, and the same reference letters are used in each of said figures to designate the same parts.

To show the mutual relationship of my improvements to each other, and one way of mounting them on a corn-planter, I have shown in the drawings the forward part, A,

of a planter, including the runners B, seedtubes 0, seed boxes D, transverse bar D, and frame bar D The bar D has its ends extendedlaterally, beyond the seed-boxes,and has at each end a cross bar or head cl fixed thereto and stayed by braces d. A rockshaft E extends across the planter and has bearings in the seed-tubes through which it passes, and in brackets d which are fixed to and pendent from the heads (I. It will be evident, however, that the improvements shown, described, and herein claimed may be incorporated in planters ofdifferent construction, difierent organization, and different type or class from the part planter shown.

The seed-cup wheel G is formed in two parts, a central part G and outer annular disk part G The part G has an ordinary circular series of seed-cups, g, with annular flanges g at their lower sides. An annular flange 9 also surrounds the central opening 9 in the disk G and has recesses g therein, one on a radial line between each seed-cup and the one next to it. The part G is a bevel pinion, with larger cogs 9 arranged alternately with smaller cogs g"'. The larger cogs g extend radially from the body part of the pinion G, see Fig. 10, and fit the recesses g in the flange 9 see Fig. 9, and hold the parts Gr, G of the seed-cup wheel so that they revolve together, and in such manner that they can be easily and quickly put together in proper relative positions, and disks G with diiferent sized seed-cups be readily substituted when desired. Each seed-cup wheel revolves on a pendent pivot stud g which projects centrally of and from the pinion G, and is journaled in a bearing g in a plate g which projects inwardly from one side of the central opening 9 in the seed-box bottom. The outer ends of the cogs g rest and slide upon the wall of the opening g in the seed-box bottom, and the annular flanges 9' rest and slide on said bottom, and thus support and steady the seed-cup wheel in its revolutions.

Beneath one side of each seerl-cup-wheel a bevel pinion e is mounted on the rock-shaft E, as hereinafter described. The pinions a each have cogs e in pairs, with narrower interdental spaces e between the two cogs of each'pair and broader interde'ntal spaces a between the pairs of cogs e. The smaller cogs g of the bevel pinion G are adapted to act in the counterpart narrow spaces e between the two cogs e of each pair, and the larger cogs g are adapted to act in the larger counterpart spaces 6 as shown at Fig. 11'. When the seed cup wheel is removed from the seed-box for any purpose, it can be easily, quickly and properly replaced relatively to the drive pinion e, to cause the seed-cups as they are revolved in their circular orbit, to register or coincide successionally with the opening 11 in the seed-box bottom, as hereinafter described, by simply replacing it in such position that the cogs g y, will engage with the counterpart spaces in the bevel pinion e as hereinbefore described.

The rock shaft E is given a partial rotation in the direction shown by the arrow at Fig. 13, by means of one of the forked levers e coming in contact with a tappet hon the checkrower line H, and being tripped orswung rearwardly thereby, to give such motion to the rock-shaft. The forked levers, as is common, are each mounted loosely on the rock-shaft E, and when either forked lever is swung rearwardly it acts upon a lug h which is fixed to the rock-shaft, and thus gives motion in one direction to the rock-shaft, and the tappet then escaping from the rearwardly inclined fork and thus releasing said fork, a spring J, as hereinafter described, returns the rock shaft or gives it a reverse motion,and thelug h acting on the forked lever returns it to its normal position and ready for action by contact with the next succeeding tappet. \Vhen one forked lever is being thus acted on, the other remains inactive, as the lug h next to it, swings away from it when acted on through the rock-shaft by a tappet, and swings back to it when acted on by the spring J.

Each bevel pinion e hereinbefore referred to, is fixed to one end of a sleeve K, which is loosely mounted on the shaft E, and has fixed to its other end a wheel M, having teeth 'm, whereby the pinion e and wheel M on each sleeve K revolve simultaneously with each other. The sleeves K are located, as shown at Fig. 16, each with the toothed wheel M which it carries, exterior to and preferably on the side of the seed-box toward the center of the planter. Adjacent to one side of each toothed wheel M an arm N is bolted and fixed to the shaft E. A pawl 12 is pivot-ally connected with the outer end of the arm N, in such manner that the lower end of said pawl hangs loosely over the wheel M, and is prevented from being thrown back out of its working IIO and fixed as before stated to the rock-shaft,-

to move therewith, but they may be separate parts, and be fixed separately to the rock-shaft, so that they have simultaneous movements with said shaft. A plate R, bolted to the side of the seed-box has the outer ends of detents r, r, pivoted thereto, which detents project toward each other and are held by their own gravity incontact with the upper part of the wheel M, except when one of them is raised therefrom, as hereinafter described. The detents a", r, are preferably located on the inner side of the plate R, and the pawl 12. and arm N on the outer side of said plate, which thereby acts to prevent them interfering with each other, see Fig. 16. A bracket or guard r is bolted to the plate R at its upper end, extends over and protects the parts between it and the seed-box, and has a bearing r at its lower end for the shaft E.

Assuming the parts shown at Figs. 13 and let to be in their normal positions there shown, and the forked levers and other parts to be in their normal positions shown at Figs. 1, 7 and 8 by full lines, and a forked lever to have been tripped or swung rearwardly by contact with a tappet h, as shown by dot lines at Fig. 7, and to have given a partial rotation to the rock-shaft E, in the direction shown by the arrow at Fig. 13, such movement of the rockshaft will by means of the arm N,-carry the pawl n to the position shown at Fig. 15, and said pawl being in contact with one of the cogs on Will force the wheel M and pinion 6 around to the positions shown at Fig. 15, and this partial rotation of the pinion 6 will impart to the seed-cup wheel a partial revolution and bring one of its seed-cups beneath the cut-off where it will register with the aperture d in the seed-box bottom and deliver its contained charge of seed therethrough and to the seed duct 0 in the seed-tube. When the wheel M is partially rotated as last described, the trip 47. will be carried from beneath the detent or detent pawl r and permit said detent to drop with its end in advance of the tooth m next succeeding the one last acted on by the pawl 42, see Fig. 15, to arrest the further forward movement of the wheel M and seed-cup wheel, and at the same time the detent 1' will fall from the cog m which supported it, and with its point in rear of the same cog, and serve to restrain the wheel M, pinion e and seed-cup wheel from any backward movements that might arise from the backward movement of the arms N, n and trip n from any jarring or jolting of the planter, or from any other accidental cause.

At Fig. 17 the last described full forward movements of the parts are shown as only partly executed, the detent r still sustained on the cog in rear of which it falls, and the detent 0" yet sustained above the cog m by the trip n After the full forward movements hereinbefore described, of the rock-shaft, arm N, wheel M, sleeve K, pinion e, and seed-cup wheel, the spring J acts, through the hook arm n on the shaft E, to rock said shaft ina reverse direction to that last described, and thereby return the arm N, and trip a and arm n to the positions shown at Figs. 13and 14, while the wheel M, sleeve K, pinion e and seed-cup wheel remain stationary. arm n in making the return movement last described, comes in contact with the detent r and trips it, or raises it and holds it out of contact with the tooth m with which it was last engaged, as shown at Figs. 13 and 14, and in position for permitting another partial rotation forwardly of the rock-shaft, arms N, 41 trip arm n sleeve K, pinion e, and seed-cup wheel, as and for the purposes hereinbefore described.

It will be seen from the foregoing that the oscillating movement of the rock-shaft E in one direction on its axis, and given to it by a forked lever, will by means of theinstrumentalities described, impart apartial revolution to the seed-cup wheel, and that a reverse movement of the rock-shaft, given it by the spring, does not act upon the seed-cup wheel, and hence that the'seed-cup wheel receives, through the instrumentalities described, an intermittent revolution, or is intermittingly revolved in one direction by the oscillatory or rocking movements of the rock shaft, for the purpose of bringing the seed-cups of its circular series in succession over the discharge opening 01 for the delivery of their contained seed to the seed-duct c.

The seed-tube (see Fig. 12) has in addition to its ordinary seed-duct c, a chamber .0 in front of and separated therefrom by a partition c which terminates at its lower end a short distance above the lower end of the seed-tube. The discharging valve S is lo cated below the lower end of the partition 0 and is there pivoted at s to the side walls of the seed-tube. The valve S has a straight arm 3 projecting tangentially from its center, and a curved arm 5 also at a tangent to its center, and having at its outer end an arcshaped arm .9 with a curve concentric with the axis of oscillation of the valve. The arms 5 s and one end of the arm 3 form the sides of a U shaped pocket or seed-cup 8 An arm 8 projects from the valve S, and is pivotally connected at its outer end with the lower end of a linker connecting rod T, the upper end of which is pivotally connected with a crankarm 8 which is fixed to the shaft E beneath the seed-box and within the chamber 0 (See The trip,

Fig. 12.) The arms of the valve S are of such close it, and to receive on its outer concave,

now upper side the charge of seed which is dropped at the same time that the valve S discharged seed from the seed-cup s as last described, and when the spring J then gives the reverse or return movement to the rockshaft, while the seed-cup wheel is unmoved and stationary, the valve S will be swung back to its normal position shown by full lines, and in so swinging, the seed contained on the arm 8 will be scraped backwardly and drop into the seed-cup 3 ready for discharge by the next swing of the valve S into the dot line position, as hereinbefore described, and ready to receive on the upper concave side of the arm .9 the charge of seed delivered by the seed-cup wheel at the simultaneous movement thereof. The arm .9 closes the lower end of the seed-duct a so quickly when the valve S swings to discharge seed from the seed-cup s, that all seed dropping toward it, at the same time,will bereceivedon the arm s and thus prevents all dribbling of seed in the row. When the rock-shaft E is given an oscillating mo tion, as hereinbefore described, to impart a movement to the seed-cup wheel, the crank arm 8 will be turned into the position shown by full lines at Fig. 18, and by dot lines at Fig. 12, and in swinging into such position will by means of the rod T turn or swing the valve S into the position shown by dot lines at Fig. 12, and in swinging into said position the velocity of the valve will be controlled by the rate of speed of the planter,the greater the rate of speed of the planter in its line of travel, the greater the velocity of the valve S, hence the valve not only throwing its contained charges of seed downwardly, but also rearwardly, Will deposit them uniformly in the soil, and not, as is the case with ordinary planters, deposit the seed too far ahead when the planter moves with greater velocity, and too far back when it moves with diminished velocity. The greater the rate of speed of the planter, the greater the velocity of my improved valve S, and hence the charges of seed will be thrown rearwardly with a force proportioned to that with which they are thrown forwardly by the forward motion of the planter, and be dropped to their places in the ground with the same regularity as if all of the forward movements of the planter were at a uniform rate of speed.

In using a check-row planter with seeding devices operated by a check-rowerline, it is not convenient nor always practical to stretch said line for finishing-rows, or other very short rows that may be to plant, and in such cases it is desirable to provide means for operating the rock-shaft E,by which the driver can operate it. Such means are shown partly at Fig. 1, and fully at Figs. 20, 21 and 22, as I prefer for the purpose, and which are not claimed herein, as they are claimed in an application, Serial No.4:20,959,prepared of even date herewith and filed February 10, 1892. Such means consist in foot pedals V, hinged at their forward ends at o to brackets e which are fixed to the bar D and pivotally connected at their rear ends, each, to one end of a link rod '0 the other end of which is pivotally connected at w with ears to which project from an arm or tappet 'w of a stirrup WV. Arms 20 also project from the tappet 10 and are loosely journaled on the shaft E. An arm W made in two parts 20 having confronting grooves which fit over the rockshaft is fixed thereto between the arms 103 by a bolt 10 which fixes the parts to to each other and to the rock-shaft. The arm W serves as a keeper to hold the stirrup WV against movement lengthwise of the rock shaft E, while permitting it to oscillate thereon. "When the foot pedals, or either of them is swung downwardly, as shown by dotted lines at Fig. 22, the tappet u; will come in contact with the outer end of the arm W and carry it around to the position shown by dotted lines at same figure and thereby give a partial rotation to the rock-shaft to an extent limited by the outer ends of the brackets 11, to operate the seed-cup wheels, as hereinbefore described in reference to the operation of the rock-shaft by the forked levers. The foot pressure being then removed from the foot pedal, the spring J will give a reverse movement to the rock-shaft as hereinbefore described, and restore the foot pedals, the stirrups W and arms W again to their normal positions, and ready for a repetition of the same movements and results.

When the stirrups W, arms W, link rods '0 and foot pedals V are turned into the relative positions shown by dot lines at Fig. 20, these parts will sustain themselves in such positions, and permit of the rock-shaft being oscillated automatically by the check-rower line and intermediate devices gearing it with the rock-shaft, and by the spring, without any motion being given to the foot pedals, which remain stationary, until again needed for planting the short rows.

The cap plate X over each seed-cup wheel is of ordinary construction, having an ordinary annular opening ac, coincident with the circular series of seed-cups g. No cut-0d is shown in the drawings, and any ordinary or desired cut-01f may be used.

The forward guide pulleys Y are each journaled on a bracket g, which is fixed to a head d as hereinafter described. The rear guide pulleys y are journaled on short journals which are fixed to said head. These guide pulleys for the check-rower line, are of ordinary construction and may be mounted as described, or in any other way that will adunit of the use of my improved check-rower line dofier Z, as hereinafter described.

The dofier Z consists of a U-shaped main portion, the upper limb z of which is shorter than the lower limb z in order to incline the llmb connecting bar 2 from a right angle to sa1d limbs, as shown. One side of the limb z is extended outwardly, upwardly and laterally thereof, to form a guide finger a for the check-rower line. The limb z is journaled (see Fig. 6) on a stud c which projects from the bracket y, through which stud and bracket a bolt 2 passes, on which the pulley Y and upper limb z of the doffer are journaled. The upper limb a has a recess in which the nut on the upper end of the bolt 2 rests, to facilitate the passage of the check rower line thereover, as hereinafter described. Alugz projects from the end of the limb z, and is turned downwardly over the outer rounded end of the bracket y, (see Figs. 4: and 6,) to engage with a shoulder 2 on said bracket, to limit the movement of the doffer when it is swung into position for retaining the checkrower line on the guide pulley, and to engage with a shoulder a on the bracket when the doffer is swung to discharge or dofi the checkfower line from the guide pulleys and forked ever.

At Figs. 1, 2, 3, 7 and 8 the doffer Z is shown in the position it occupies when the checkrow chain H is in place on the guide pulleys Y, 11 and in which position the bent finger 2 assists in retaining the check rower line H. The doffer is held in the position just described by contact of the lugs 2 .2 and by a rod z" which is connected at one end with the arm 2, and which passes through an eye 2 on the seed-box, and has a shoulder 2 (see Fig. 7,) which is engaged with said eye to lock and hold the doffer in place. WVhen it is desired to dofi or free the check-rower line from the planter to turn it around at the end of rows, the catch or shoulder z is released from the eye 2 by raising the rod 2 Then by pulling the rod c the doffer will be swung around until its lug .2 will come in contact with the lug .2 as shown at Fig. 4. In swinging as last described, the inclined bar 2 will force the check-rower line out of the groove in the pulley Y, and the lateral pull of the line will then draw it up the inclined bar .2 and over the pulley Y, at the same time lifting it sufficiently to free it of the forked lever, and the horizontal pulleys y will then permit of its escape entirely from the planter. When the planter is turned around, the check-rower line is placed over the doffer, the doffer then turned into position to engage the line with the pulleys, and the catch 2 then engaged again with the eye 2 to hold the doffer in position for planting operations.
