Patented June 9,1914.

Application filed November 25, 1910. Serial No. 594,187.

To all whom it may concern:

Be it known that I, LAUGHLIN M. BUCH- ANAN, a citizen of the United States, residing at Kewanee, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Corn-Planters, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to corn planters, and has for its object to provide a new and improved planter in which all the operating parts and the supporting wheels are carried by a single frame instead of by two frames hinged together as has heretofore been the general practice in corn planter construction. I accomplish this object as illustrated in the drawings and as hereinafter described.

What I regard as new is set forth in the claims.

In the drawings, Figure 1 is a longitudinal vertical section on line 1.1 of Fig. 2, illustrating the construction of my improved planter; Fig. 2 is a plan view; Fig. 3is a horizontal section on line 3-3 of Fig. 1; Fig. 4 is a horizontal section on line 4-4. of Fig. 1; Fig. 5 is a vertical section on line 5--5 of Fig. (3, showingthe construction of the driving sprocket; Fig. 6 is a section on line 66 of Fig. 1, showingthe construction of the wheel spindles and the arrangement of the driving sprocket and clutch mechanism; Fig. 7 is a rear elevation, the tongue being in section; Fig. 8 is a detail, being a partial plan view illustrating the drive-shaft by which the seed-plates are operated and the connections thereof; and Fig. 9 is a section on line 9-4) of Fig. 8.

Referring to the drawings, 10-11 indicate parallel bars extending transversely of the machine. Said bars are connected by brackets 12-13, which together form what may be termed the frame of the machine.

1415 indicate runners, which are rigidly secured to the bars 10--11, as best shown in Fig. 1, and are provided at the rear with the usual standard 16 provided with a seed-duct 17 equipped with valves adapted to be operated by checkrow apparatus in the usual 1 3-19 indicate seedboxes arranged in the usual way and over the standards 16, said seed-boxes being provided with the usual seed-plates.

20 indicates a check-row rock-shaft, which extends transversely of the machine and is connected with the valves in the seed-ducts 17 in the usual way. ill-2 indicate checkrow forks mounted on the rock-shaft 20, and 23-2 l the usual guide-rollers for guiding the chcck-row wire into engagement with the forks 21-22, as usual.

25 indicates a spring for restorin the rock-shaft 20 to its normal position after it has been actuated.

26 indicates the usual seed plate shaft, which is journaled in suitable bearings 27 carried by the brackets l2-13 and is geared to the seed-plates as usual.

28 indicates the shoes of the runners 14 15, which, as shown in Figs. 3 and 4:, are flat on the inside so that their inside surfaces are inline with the line of movement of the machine, the rear portions of said runners being wider and being convex on their outer faces, as shown at 29 in said figures.

30 indicates the tongue, which is secured to the main frame and is braced by a brace 31, as shown in Fig. 2.

32 indicates the seat, which is mounted on the rear portion of the tongue back of the main frame.

3334 indicate crank-axles, which are pivotally mounted in brackets 353G3738, respectively, at opposite ends of the bar 11v of the main frame so that said axles may rock in their bearings.

39 indicates a shaft, which is fitted in the horizontal portion of the right-hand axle 34, as best shown in Fig. 9, said shaft being employed to transmit power from one of the supporting wheels to the seed-plate shaft 26, as hereinafter described.

40 l1 indicate wheel-spindles.

integral rod or bar, the inner end portion of which is disposed horizontally andhis fitted in bearings in the brackets 35-36, as hereinbefore described,the intermediate portion 42 thereof being bent at right angles with the horizontal portion and the spindle 40 formed by the outer end portion which is bent so that it forms an angle slightly greater than a right-angle with the intermediate portion42, as shown in Fig. 2.

43 indicates the left-hand wheel, mounted on the spindle 40. The right-hand crank axle 34 is tubular to receive theshaft 39 and near its outer end carries an arm 44 g The V crank-axle 33 is preferably formed of an 7 spends with the intermediate portion 42 of the left-hand axle. Said arm44 carries at its lower end the spindle 41 which, as above suggested is preferably formed integral therewith, said spindle being arranged at an obtuse angle with said arm 44 and carrying the right-hand wheel 45, as shown In Figs. 2 and 6. It will be noted that by the construction described the wheels 4345, when in the positionshown in Fig. 2, which is the normal position, are inclined to the line of draft so that they are farther apart at the front than at the rear, and as they are set back of and slightly outside the inner faces of the runners they act as covering wheels to throw the dirt back intothe'furrow after the seed has been dropped therein. The two wheels being inclined in opposite directions, the side-draft is equalized so that the machine may easily be guided in astrai'gl'it line. The crank axles and wheels at the opposite sides of the machine are independently adjustable so that either wheel may be raised or lowered and at the same time be moved forward or backward independently of the other, and when the ma chine is transported from one field to another they may both be set so as to run substantia'lly parallel with the line of draft by 33 -34, respectively, and the hand-levers be-.

ing pivotally connected therewith adjacent tothe foot-levers. Locking egments 48-49 are secured to' the bar 11 adjacent toas the hand-levers 46'47,Q respectively, shown in F i'gs. land 2. The hand le'vers operate through their respective foot-levers by means of rods 54 and springs 5253 mounted on said rods, as shown in Fig. 1,

the arrangement being such that when one of the levers, as 47, is drawn backwardit will operate through its spring 58 to depress the foot-lever 51, and by locking the lever o in any desired position of adjustment by means of its segmental rack 49 the corresponding axle may be locked in position. This locking, however, does not hold the axle rigid, as the spring 53 permits it to yield slightly. The lower ends of the rods 54 pass through suitable perforations in the levers 50451 and nuts 54 are screwed upon the lower ends of said rods 54 below the levers 505l, as shown in Figs 1 and 7, so

7. that when the levers 46- 47 are moved forward beyond a certainpoint they will act to positively lift the levers 50 '51. It will be obvious that when the axles 33'34 are rocked to lower the wheels the efiect is to raise both runners out of the-ground. This may be raised or lowered independently of the other to adjust the corresponding runner vertically and maintain it in proper 010- c erative position. 7 7

As has been explalned, the crank-axle 34 ;is tubular and incloses the shaft 39, Whichshaft carries at its inner end .a sprocket- 7 '41. Preferably the sprocket-wheel 60 is mounted upon a sleeve 61 carried by anfarm 62 fixedly secured to the arm 44' of the;

crank-axle 34, as shown in Fig. 6. Said sprocket-wheel is provided on its outer face with lugs 63, preferably two in number,-

which are adapted to engage corresponding lugs 64 carried by a disk 65 which ismounted on and secured to the inner portion of the hub ofthe wheel 45, as best shown in Fig. 6, I thus provide clutch-members through which the shaft 39 is driven from the wheel 45 and at the same time the ad j ustment of the wheel incidental to the rocking of the crank-axle 34 is not interfered with. Furthermore,- the wheel 45 may be partly rotated in a reverse direction, as is necessary inturning corners, without reverse ing the rotation of the seed-plate shaft.

If desired, it will be understood that instead of driving the seed-plate drive-shaft from one of the wheels only it may be driven from both wheels by duplicating at the left hand side of the machine the construction shown at the right-hand side thereof and-- using a ratchet-wheel for connecting the driving mechanism'operated by one of the, wheels with the seed-plate drive-shaft, or

using a divided seed-plate drive-shaft. The

claims are therefore not to' be construed as 7 being limited to driving the seed-plate driveshaft from a single wheel only; Further? more, it should be understood; that while I have described with considerable particularity the embodiment of my invention shown in the accon'i'p'anying drawings, my

' invention is generic in character and is not limited to such specific embodiment, except seed-depositing means carried by saidframe, combined covering and carrying wheels ta ranged at an angle, to the line of draft, 1%

means separately connectingsaid wheels respectively with said frame, means for independently adjusting said wheels vertically and for varying the angular relation of said wheels to the line of draft.
