ALBERT SCOTT WININGS, OF LAKE CITY, ILLINOIS.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 373,212, dated November 15, 1387.

Application filed March 14, 1887. Serial No. 230,762. (No model.) i

To all whom. it may concern:

Be it known that I, ALBERT ScoTT WIN- INGS, of the town of Lake City, county of tion.

My invention relates to check-row cornplanters; and it consists in certain details of construction and combinations of parts, as hereinafter set forth and claimed.

In the drawings accompanying and forming a part of this specification, Figure 1 is a plan of my machine. Fig. 2 is an end view of the same, with one wheel removed. Fig.3 is a vertical section on dotted line in Fig. 1. Fig. 4 is a plan of the mechanism used to impart the motion of the check-row levers to the dropping mechanism of the corn-planter. Fig. 5 is a rear view of a first drop-plate, showing the backlash-pawl and the lift-pawl that 0perates the second drop-valve. Fig. 6 isa side view of afurrow-opener and shank, the latter being vertically cut to expose the second dropvalve. 7

The main frame is composed of two parallel transverse bars, 3 and 4, and end pieces, 5 and 6. The tongue 9 is secured to the longitudinal center of bar 3, and is braced laterally by angle-bars 10 and 11. Brackets 44 and 45 on end bars, 5 and 6, respectively, carry spindles for wheels 1, and said wheels are provided with obtuse-angle peripheries 2, as shown in Fig. 1.

The seed-

boxes

7 and 8 are mounted on an independent frame composed of

bars

29 and 30. The guide-frames 40 and 41 for the checkrow line 48 are secured to the outer edges of the seed-boxes in amanner permitting longitudinal adjustment, (see Fig. 2,) in which adjustable bolts and longitudinal slots are used to effect this result.

The check-row levers 42 and 43 are bifurcated in the customary manner to receive the check-row line, and are rigidly secured to vertical shafts, (see 49 in Fig. 2,)that have hearings in the guide-pulley frames,'and con nect with'the dropping mechanism in a manner to be hereinafter set forth.

p The main frame carries seat 13 on support 12.

Brackets

19 and 20 on the rear transverse bar,4, provide bearings for rock-shaft 18. A hand lock-lever, 35, is rigidly secured to shaft 18, and an arc-formed rack, 36, loosely mounted on the shaft and secured to the seat- 55 support, co-operates with the catch of the hand-lever to hold the rock-shaft in various positions of rotative adjustment. and 15, the one to the rear and the other to the front of the rock-shaft, connect rigidly with said shaft through arms 16 and 17, respectively.

(logged

sectors

21 and 22 are rigidly mounted on shaft 18, at the ends thereof, and intermesh the one with rack 23 and the other with rack 24. The racks are both vertical, and are secured to the sliding guide-

frames

25 and 26. Guide-frame 25 is secured to bars 29 and and to seed-box 7. Guide-frame 26 is secured to

bars

29 and 30 and to seed-box 8. Guideways 27 form bearings for frame 25. Guide ways 28 form hearings for frame 26.

Descending from each seed-box in the customary manner is a tubular shank, 54, that acts as a corn-conveyer, and in front of each shank is a furrow-opener, 52, extending upwardly and backwardly in general contour, and having the undercut bevel 53 at its lower front termination. Immediately above the front edge of each furrow-opener is a vertical roller, 51, tapering downwardly after the man ner of an inverted-cone frustum, the said roller having free rotation on its vertical axis. Secured to the shanks at opposite sides thereof, in amanner permitting vertical adj ustment,are covering-

cutters

37 and 38, the one longer than the other, and both curving toward and over the furrow at their rear terminations. As seen at in Fig. 2, vertical adjustment is Pedals 14 provided for in the well-known expedient of 9C a longitudinal slot and adjustable bolts, and other meansfor accomplishingthe same result will be readilyapparent to those skilled in the art.

At the lower termination of the vertical shaft of check-row lever 43 is crank-arm 62, (see Fig. 4,) extending forwardly, and having in the lower surface of its extended end a downwardly-projecting pin. The shaft of checkroW lever 42 is provided at its lower termination with the rearwardly-projecting crank-arm 63, in the outer end of which is also a downwardly-projecting pin. A bar, 31, extends across the planter, tangential with the front of the seed-plates, and carries pawls 66, that swing vertically and engage the peripheral teeth with which the seed-plates a e provided. Secured to the frame adjacent to the bar 31, and in line with the motion of the pawls, are stops (3?. A slotted forwardly-extending arm, 64, integral with the bar 31 and at right angles thereto, provides a bearing for the pin of arm 62 and a means for imparting the oscillatory motion of the check-row lever 43 to the rectilinearly-reciproeating bar. The slotted arm extends rearwardly from the bar 3t, and connects through oscillatory arm 63 with the shaft of the check-row lever 42.

A spring, 33, (shown in Fig. 1,)connects with a spur, 32, on bar 31, and with a lug, 34, on the front bar of the box-supporting frame, and returns the said bar 'to its normal position after the completion of a throw of a check-row lever. At the rear of each seed-plate is aliftpawl, 59, that rests on the teeth of the plate and eonnects,through rod 58, with the wei hted end 57 of second drop-valve, 56, which automatically closes the seed-conveying tube 55.

The bar 31, as shown in Fig. 4, is at the termination of its operative stroke and the drive pawls are pressed firmly down and against the peripheries of the seed-plates by stops 67. As the bar is returned by the action of the spring, the pawls are drawn free of the Stops and each passes over and falls behind a tooth of a seed-plate preparatory to a subsequent stroke. While the seed plates are in rest the lift-pawls are in their lowest positions, and the second drop-valvcs are, as a consequence, closed. The li ftpawls rise promptly at the first motion of the seedplates and fall again before the motion has ceased, so permitting the escape of the corn from the second drop-valves and the reclosing of said valves before the upper plates are in position to discharge. This will be understood by reference to Figs. 4 and 5, where it will be seen that the lil't-pawls have fallen before the completion of the rotation of the seed-plates.

Backlaslrpawls 60 are provided in order to insure greater accuracy of operation, and as a matter of convenience they are'pivoted to the free ends of the lift pawls.

The frame carryingthe planting mechanism has free vertical motion in the main frame, and its relative position is adjusted and maintained by the rack-and-piniou mechanism operated through the rock-shaft by the pedals and handlever. The runners or furrow-openers may be held uniformly at any desired depth of penetration by the lock-lever and its coacting rack, or the locking mechanism may be thrown out of operation and the runners be constantly guided by the action of the feet on the pedals.

The wheels by running alongsidethefurrowopeners aflord uniform and accurate guides therefor, and the accuracy of such guides is increased by the beveled conformation of the periphery of the wheels, which enables said wheels to cut through incidental obstructions and move more nearly in a right line.

The undercut bevcls 53 avoid a possibility ofthe furrow-openers digging below the plowed ground or catching under obstructions in a detrimental manner.

The edges 52, by their upward and backward inclination, carry stalks, &c., in contact with the rollers 51, which are enlarged gradually toward their upper ends to prevent farther ascension, and which revolve readily in the direction of the greatest strain, effecting a detachment of debris that might otherwise accumulate and inj uriously affect the operation of the machine.

The corn is covered by cutters that enter the ground vertically and curve toward and over the furrow at their rear terminations, drawing pulverized soil over the corn and pressing it with sufficient firmness to insure germination. To provide for the passage of trash, one cutter is extended to the rear of the other, and this arrangement is efficacious in providing for porosity of the covering-soil, which might become packed to an injurious extent if subjected to the simultaneous and opposing pressure of the two cutters. Owing to the individual conformation and relative arrangement of the covering cutters, the corn is covered with a slight ridge, which may be more or less pronounced by variations in the curve given to the rear ends of the cutters; but whatever the angle of curvature or whatever the degree of pressure, the ground immediately over the corn will not be packed by direct vertical pressure or glazed by frictional contact.

A tendency, noticeable in planters as commonly constructed, to vary the accuracy of checking by an adjustment of the furrow-opcners with reference to depth of penetration, which tendency is caused by a tilting forward or backward of the check row levers with relation to the final drop of the planter, is avoided in my machine by the absolutely vertical motion of all the parts in adjusting the depth of the furrow-openers.

Variation in planting caused by using differently-paced teams is intended to be regulated by the simple expedient of adjusting the checkrow levers backward or forward on the seedboxes, the slots in the arms of the reciprocating bar '31 being long enough to permit a sailicient degree of adjustment.

The resistance of the check-row-line knots to the motion of the planter is reduced by the construction that requires the levers to be moved only enough to impart by direct application of force a partial rotation of the seedplates equal to the distance between cells, the intermediate mechanism common to detachable check-rowers being dispensed with.

In general operation the machine does not vary essentially from other planters of the same class, the check-row line lying across the field adjacent to the path of the planter, the

check-rowlevers being operated by the knots on the line and returned by a spring, and each lever effecting a drop in both seed-boxes; but,

owing to the compactarrangement of the parts, the draft is lighter and the machine moresensitive to the motions of the team, making ac curate driving more easy of accomplishment.
