JAMES DRUMMQND SOHOFIELD, OF DALLAS, TEXAS PLANTER.

SPECIFICATION forming part of Letters Patent No. 641,468, dated J'a'nuary' 16, 1900. Application filed September 14:, 1899. Serial No. 730,458- (No model.)

To aZZ whom it may coir/corn.-

Be it known that I, JAMES DRUMMOND ScHo- FIELD, a citizen of the, United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Planters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in combined cotton-seed and corn planters.

The main objects of the invention are to perfect a machine of the class described which is adapted to drop and cover either corn or cotton-seed at regular intervals, the said machine being positive in its working, adapted for either planting by very little change, that is simple in its operationand most readily understood, to provide the same with a new and improved feed device, and also a new and improved drive mechanism. 7

Various other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a general or perspective view of a combinationplanter embodying my invention. Fig. 2 is a transverse vertical sectional view on the line 2 2 of Fig. 5. Fig.3 is a top plan view of the corn-disk in detail: Fig. 4 is a perspective View of the knocker-plate. Fig. 5 is a plan view of the planter with the hopper removed. Fig. 6 is a longitudinal sectional view of the rear portion of the same, the view being taken on the line 6 6 of Fig. 5. Fig. 7 is a detail in perspective of the cast yoke employed in the frame.

Fig. 15 is a detail View of one of the journal-castings in which the crank-axle of the machine is journaled.

Similar numerals of reference indicate simi lar parts in all the figures of the drawings.

In practicing my invention I employ the usual steel frame or side bars 1 1, the rear ends 'of which are downwardly curved and constitute the shovel-standards 2, which carry the covering-shovels 3 3. The front ends of the side bars are also downwardly disposed and have bolted thereto cast-metal bearingbrackets 4 4, which are provided with lugs 5 5, that embrace the front and rear edges of the front ends of said beams or side bars, and is each provided with a bearing-socket 6 for the accommodation of the rotatable drive= axle 7. At the center of the aforesaid axle is secured a ground-wheel 8, that revolves with the axle, and at each side of the ground-wheel, which, as will hereinafter appear, is a driver, the axle is formed with cranks 9, the same being disposed at a variance.

Rising from the side bars are the usual inclined handles 10, the same being bolted at their lower extremities to the said side bars by means of bolts 11, and in rear of the same supported upon the upper ends of vertical standards 12 a binding rod 13, passing through the lower ends of the standards 12 and the said side bars, whereby a rigid frame is produced.

Located between the two side bars of the frame and extending vertically thereabove is a cast-metal yoke-frame let, a detail of which is shown in Fig. 7 of the drawings. This yoke is formed with opposite flanged frameembracing feet 15, having holes for the reception of the bolts 11, by the aid of which and the flanges on the feet the same is held rigidly in position and also serves as a material brace for the planter-frame. This yoke is formed with two oppositely-arranged vertically-disposed elongated side openings 16, and between the same with an upper central opening 17, from which projects a forwardlydisposed horizontal bracket 18, having a boltreceiving slot 19 at its extremity, and with a lower central opening 20. The upper corners of the yoke are also formed with lugs 21, which are angular in shape and which are designed to pass through and support castmetal bearing-plates 22 22, one for each lug. Each of these bearing-plates is provided with an oblong or other angularly-shaped opening ICO 23, which alines with and receives the lug 21, and in advance of the same with a bolt-hole 24, which coincides with a slotted car 25, that projects forwardly from the front of the yoke and at an angle to the lug 21, adjacent thereto. Through the holes :24 and the slotted ears 25 are passed bolts 27, the same serving to clamp the bearing-plates in position upon the yoke. The upper portion of each bearing-plate is provided with a bearing-opening 28,and these receive the trunnions or bearing ends of lugs 29, that project from the under side of the hopper 30, and which are preferably cast integral with the bottom 31 thereof. The lugs 29 beinglocated in advance of the center of the hopper, it will be seen that the tendency of the hopperis to remain depressed at its rear end or side, yet at the same time the hop peris capable of being tilted forward on its 1ugs,and when this is done, as will hereinafter appear,the machine is inoperative. For thus raising and lowering the hopper the same has projecting from its rear alongside one of the standards 12 a convenient handle 32, and by springingthe same over or under a bracket 33, projecting from the standard 12, the said hopper is retained in either its raised or inoperative position or its lowered operative position.

Through the lower central opening 20 of the yoke 14 there extend forwardly the front ends of a pair of .divergent braces 34 and that of a centrally-located curved standard 35, which latter depend and support the furrow-opening shovel 36. The rear or divergent ends of the braces 34 are angled and provided with bolt-holes and receive the binding-rod '13, suitable clamping-nuts being employed for clamping the braces and side bars of the planter-frame together.

lVithin the space formed by the divergent brace-bars and the binding-rod 13 is located the discharge-spout 37, the same being formed of sheet metal, the edges of the blank of which embrace the standard 35 and are bolted thereto, as shown. A bolt 38 serves to bind the front ends of the divergent braces and the standard 35 together, it being apparent that the draft or strain upon the standard 35 is borne by the steel side bars, the strain being transmitted thereto by the divergent braces.

Glamped upon the horizontal bracket 18 by a bolt 39 is a bearing-yoke 40, the same extending rearwardly through the upper central opening 17 in the yoke 14 and having a general T shape, in that the rear end is formed with a transverse head 41, the said head being longitudinally bored, as at 42, for the reception of a short counter-shaft 43. At one side of this bearing-head 41 the shaft 43 is provided with a small beveled gear-wheel 44, and beyond the same and the opposite end of the said head the shaft is provided with short crank-arms 45, the same being loosely connected to the cranks 9 of the axle by means of intermediate connecting-bars or pitmen 45. These pitmen are preferably each made in two sections, the inner ends thereof overlapping to form a sliding joint, the parts being maintained in their adjusted position through the medium of adjusting bolts 46. This completes the description of the planter-frame and the parts carried immediately thereby, and I will now proceed to describe in detail the feed mechanism and its operation.

The bottom of the hopper is provided with a central circular opening 47, from which depends an annular flange 4S, bridged by abridge-piece 49, at the center of which is a vertically-disposed internally-threaded bearing lug or stud 50, surrounded at its base by a slightly-elevated annular track 51, all as best shown in Figs. 10 and 11 of the drawings. The opening 47 is surrounded at its topby an annular depressed track 51, and at one side of the opening near the Wall of the hopper is a segmental cottonseed-dischargingopening 52. Rotatably and removably mounted on the bearing-stud 50 is a cup-shaped beveled gearwheel 53, the same having formed on its under side an annular track 54, which coincides with the track 51 of the stud. The teeth of this gear mesh with the small beveled gearwheel 44, and the upper edge of the gear is flush with the bottom of the annular track 51, and from it above the track 51 there rise a pair of diametrically opposite studs 55.

56 designates the corn-disk, which is provided with a central opening 57, the opposite sides of which are notched, as at 58, (see Fig. 3,) to engage with the studs 55. This disk has its edges provided with curved recesses 59 and is of such dimensions as will adapt it to be removably and rotatably seated in the depressed track 51 of the hopper-bottom, the

said recesses moving over a discharge-open-' ing 60, (see Fig. 7,) formedin said bottom at one side of the opening 47 and within the track 51 heretofore mentioned. It will be seen that the cup-shaped gear being rotated or driven by the driving mechanism heretofore described the corn-disk will be likewise rotated, each of its recesses carrying the kernels of corn to and dropping them through the dischargeopening 60.

In Fig. 13 I have illustrated the cotton-seed discharge, and it comprises two members, the one or upper member being adjustably mounted upon its companion. The lower member 61 comprises a segmentally-shaped plate 62, from the opposite ends and sides of which depend flanges 63, the said plate being of such dimensions as to adapt it to completely close the segmental opening 52 heretofore mentioned. Half-round bearing-stems 64 project from the opposite longitudinal sides or edges of the plate, the outer stem being somewhat longer than the inner stem, and therefore projecting through an opening in the wall of the hopper. This outer stem is also provided with an aperture 65, which is countersunken at its lower end, and the two stems are designed to rest in half-round bearings or depressions 66, formed in the hopperbottom at each side of the discharge-opening 52. The plate 62 is also provided near its opposite ends with discharge-openings 67, at one side of which are formed triangular flanges 68. The upper or movable member of this feed device comprises a half-round stem 69, which coincides with and is mounted upon the stems 64 of the lower member. The stem 69 is provided with oppositely-disposed triangular flanges 70, the same being companions to and opposing the flanges 68, the two sets of flanges combining to cover or partly uncover the discharge-openings 67 of the plate 62. The opposite ends of the stem 69 are provided with depending half-round lugs 71, the same serving as guides in the movements of the upper member upon the lower member. The stem 69 is further provided near its outer end with a slot 72, which registers with the aperture in the stem 64, and upwardly through the said aperture and the aforesaid slot is passed an adjusting-bolt 73, at the upper end of whichjs a thumb-screw 74 for-clamping the two stems together, and therefore securing the two members in their proper relative positions. It will be at once apparent that the output of cotton-seed may be regulated by the adj usting screw orbolt 73, and, ifdesired, that the discharge-openings 67 may be wholly closed, such'being the case when it is desired to convert the machine from a cotton-seed to a corn planter. In the latter instance it becomes necessary to provide some means for retaining the cotton-seed discharge in an inoperative state, and this I accomplish by means of the knocker device employed and which I have illustrated in detail in Fig. 4 and in operative positions in Figs. 8 and 10. This device is a simple casting, which com prises a central depending hub 74, designed to fit within the corn-disk 56, and itis formed at one side with a hood 74 in which is arrangedtheusualvibrating knocker75. From this hood project radial retaining-lugs 76, which when the device is in position in the bottom of the hopper above the corn-disk overlap the opposite ends of the plate 62 of the cottonseed-feed device and retain the same stationary. There also projects from the edge of the hood between the two retaining-lugs referred to an angular or depending lug 77, which rests within theinnerend of the inner stem 64 of the cotton-seed-feed device. At a diametrically opposite point the hub of the knocker device is provided with an angular lug 78, the same resting in a recess formed in the hopper-bottom and designated as 79. A washer is seated in. the hub of the knocker device, and through the same there is passed a winged bolt 81, the lower end of which threads removably in the internallythreaded bearing-stud 50, whereby the knocker device is held in position and serves to clamp the cotton-feed device in an immovable position.

The operation of the machine as thus arranged will be readily apparent and may be briefly explained as follows: Motion being conveyed to the cup-shaped gear-wheel 53, the same in turn rotates the corn-disk, the kernels of corn being carried by the recesses in said disk to the discharge-opening under the knocker, which latter dislodges the corn in the usual manner. In planting cotton-seed the knocker device and the corn-disk are both removed, leaving the cotton-seed-feed device free to rock or vibrate. The cotton-seed-agitating device comprises a lower disk 82, the under side of which is provided with an annular depending flange 83, notches 84 being formed therein at diametrically opposite points. The disk is of such diameter as adapts its said flange 83 to fit within the cup-shaped gear 53, the lugs 55 of said gear engaging the notches 84 of said flange 83, and therefore causing the said disk and gear to rotate t0- gether. A hollow stud 85 extends upwardly from the center of the disk 82, which stud is designated as 85,and the same is open through- -out its length, is in vertical alinement with the threaded stud 50, and terminates at its upper end in an annular flange or head 86.

The cotton-seed disk or agitating device further comprises an upper disk 87, which has an annular depending flange S8 of a diameter adapting it to fit over in a loose manner the lower disk 82, upon which it is mounted. The upper disk is further provided with a central hole 83, upwardly through which the hollow stud 85 extends, and with radially-opposite side openings 89, through which extend the agitating-arm 91 and astud 90, the said upper disk being capable of riding vertically thereon. The upper disk is further provided at its periphery with a series of radiating agitating fingers orarms 92, which are beveled on their under sides. Upon the hollow stud 85 and between the head 86 thereof and the upper side of the upper disk there is located a coiled expansion-spring 94, the same having a tendency of depressing the upperdisk yieldingly upon the lower disk, yet permitting of a limited vertical movement upon the part of the upper disk, whereby the agitating-fingers 92 are enabled to ride over obstructions located between the same and the hopper-bot tom. Within the hollow stud 85 is located a hollow bolt 95, which is headed at its upper end, as at 96, at which pointit is located above the upper end of the hollow stud 85, and at its lower end it rests upon the upper end of the hollow stud 49, with which latter it agrees in diameter. Through this hollow bolt is passed a bolt 97, the upper end of which is provided with thumb-pieces or wings 98, and the lower end of which is threaded in the hollow stud 49, whereby these parts are secured in position and the agitating device is capable of rotating with the cup-shaped gear 53.

The operation of the cotton-seed feed may be described as follows: The lower disk 82 being rotated by the cup shaped gear 53in turn rotates the upper disk, the agitatinge fingers operating in the usual manner upon the cotton-seed. The cotton-seed feed, of course, has been adjusted to regulate the output. The agitating arms or fingers 92 successively strike, ride over, and depress the raised ends of the cotton-seed discharge 69, which latter is therefore rocked or vibrated and at each rocking or vibration discharging a predetermined quantity of cotton-seed.

It will be apparent that the machine may be readily and quickly converted from acotton-seed to a corn planter, and vice versa, the operation being easily understood and obvious to the most unskilled, and also that the feed of either cotton-seed or corn is positive and takes place at regular intervals, so that the result is a regular planting. It will also be observed that the driving mechanism is all contained within the planter-frame, is most compact and simple, worn parts being readily replaced when necessity may require. The cotton-seed-feed or agitating device readily yields to any accumulation or obstruction in the hopper-bottom, rides over the same, and thus is not prevented from even temporarily performing its function and operating the vibratory feed device. By raising the hopper upon its trunnions, as heretofore described, the teeth of the cup'shaped gear are elevated out of contact with the gear-wheel 44, and hence no feed of the seed can take place. To start the feed again, it is simply necessary to disengage the lever or handle 32 from the bracket or catch 33 and lower the hopper, thus establishing a reengagement between the two gears 53 and 44.
