CORN-PLANTER.

SPECIFICATION formingpart of Letters Patent NO. 595,026, dated December 7, 1897. Application filed September 5, 1896. Serial No. 604,951. (No model.)

Z0 (all whom, it may concern:

Beit known that I, LEWIS E. WATERMAN, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Corn-Planters; and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has reference to improvements in corn-planters, and comprises the several novel and useful features hereinafter set forth.

The object of my invention is to provide a machine of compact form, great strength, light in draft, of the fewest possible number of parts, minimum weight, simple in construction, convenient to handle, and reliable and accurate in the depositing and the covering of the seed.

I attain the foregoing advantages in the construction shown in the accompanying drawings, in which Figure 1 is a plan View of a machine embodying my invention, one of the seed-hoppers being turned forward for the purpose of exhibiting the exterior base thereof. Fig. 2 is a vertical sectional view of the seeding mechanism with the seedbox thrown forward in position for changing the seed-plates. Fig...

3 is a similar view with the seedbox in operative position. Fig. 8 is a broken detail plan of the check-wire reel. Fig. 9 is a broken side ner-frame by two horizontal parallel bars A A, hinged at their front ends in a vertical plane to the front cross-bar B of the runner frame and passed through the plates 0, provided with the vertical slots 1 and seated on the transverse bar D of the runner-frame. The bars A are attached to the axle E of the WheeLframe and ,proj ecting rearwardly therefrom, furnish also a support for the drivers seat and the scraper-bar at the rear of said axle. An additional central connection between said frames exists in the system of levers hereinafter described operating from the rear end of the tongue. Each furrow-opener or runner F is followed closely by two covering-wheels G G, each of which has an independent rotation, except that one pair, utilized as driving-wheels when the machine is used as a drill, are geared together. Each pair of the wheels G has a wide interval between them at the top and a narrower interval about the width of the runner F at the bottom, so that each pair of wheels stands obliquely to the vertical, but divergent therefrom in opposite directions, for the purpose of press ing each side of the furrow-gash and crowding inwardly the earth thereon, but leaving a loose strip unpressed directly over the line of the seed for the ready passage of the young plants.

The oblique divergence of the wheels G necessitates the bowing upward of the spindle upon Which the said wheels rotate transversely of the machine and retaining the same rigidly in that position, so that the wheels may maintain their aforesaid relative position. To accomplish this, the round spindle I-I, bowed, as aforesaid, upward in a verticalplane, is held at its inner end by the sleeve J and transverse bolt K, which passes l1orizontally through the spindle II and sleeve J. The inner end of the sleeve J is held adjustably between the parallel cross-bars L L, which constitute the central portion of the axle of the rear or wheel frame. The adjustment of the sleeve J on the bars L L is effected by vertical bolts M, which are inserted between the bars L L and suitably capped over the sleeve J and the upper surface of the bars L and across the lower surface of said bars.

The drivingwvheels G are journaled, rospectively, on the boxes 2, rotative on said spin= dle. On the inner ends of said boxes are formed the beveled gears 3, which intermesh and thus unite the traction force of both of said wheels. The boxes 2 and the wheels G are held on the spindles by the nuts 4 at the outer ends and the sleeves J at the'inner end. The sprocket-wheel 5 is secured to the inner end of the inner box 2 of one of the wheels, and the sprocket-chain 6 extends therefrom to the sprocket-wheel 7 on the drilling-shaft 8.

The advantage of having the two drivingwheels at either side of the machine is based upon the fact that one of said wheels is thereby always upon the ground in position to operate whatever may be the unevenness of the surface of the ground. It is generally conceded thatthe traction of two wheels is necessary to furnish the requisite power to drive the seeding mechanism when drilling.

Referring to Fig. 2, N isthe seed-hopper, provided with transverse openings at its front corners, by which it ispivoted at the front of its, base to the bracket 0, seated rigidly on the bar D. Ears 1O 10 are formed on the bracket 0, and a transverse bolt 83, seated loosely in said ears, passes through the hopper N in the transverse openings insaid' hopper and furnishes the pivot forturning said hopper forward, as shown in Figs. 1 and 2. A recess 11, (see Fig. 1), is formed on the rear end, of bracket 0 and adapted 'to receive the bolt 12, seated on the rear side of the hopper N, which holds the latter in working position. Ahollow central downward projection N from the bottom of the hopper N serves as the centralpivotal seat of the rotating seed-plates 15.

The advantage of turning the seed-hopper N forward, as shown, consists in the fact that thereby it is rendered feasible to change the seed-measuring plates without removing the seed from the hopper. This is accomplished by suitably seating a short bolt 13 centrally in the base of the hopper and permitting the same to extend downwardly through the bottom of the hopper and through the seed meas uring and discharging mechanism seated on said bolt below and outside of said bottom and seating a thumb-nut l4 thereon below said mechanism, by the removal and replacing of which all of the seeding mechanism, being on the under side of the base of the hopper N, can be readily changed to vary the quantity of seed discharged or the mode of planting, as may be desired. The circular seed-plate 15 is intermittently rotated in check-rowing by the lug 17 on pawl 18 engaging with one of the projections 16 on the plate and moving it forward one projection. The pawl is pivotally seated upon driving-arm 61-, secured to the rock-shaft P, which is actuated in any suitable manner by the check-rower fork 19. Alug 2O atthe front end of the pawl 18 limits the intermittent progressionof the seed-plate by engaging the same at the limit of the backward drawing action of the pawl 18, and the retrogression of the plateis predirectly under said duct.

vented by the pawl 21, seated on the base of the hopper N and engaging by its gravity the projections 16 of the seed-plate.

When the machine is used to drill the seed as distinguished from hill-dropping, a gearrim 22, carrying a seed-plate 23, is substituted for theseed-plate 15 and is driven by the beveled pinion 24, seated on the shaft 8, driven from the driving-wheels G, as aforesaid. The two bevel-pinions 24 are seated at the same sides of the gear-rims 22, respectively. A rock-shaft 76 is journaled lengthwise of the machine on the bar D and provided at its frontendwitha downward bend 77 and has.

at its extremity a fork 7 8, adapted to loosely bestride the annular recess 79, formed in collar 80, which is keyed on shaft 8. The rear end 81 of the shaft 76 is projectedlaterally underone of the bars A.

When the front or runner frame is raised for turning or other purposes, the bar A presses downward on the part 81 and automatically rocks shaft 76, and thereby draws shaft S-endwise sufficiently to disengage pinions 24 from gear-rims 22.. A coiled spring 82 on the central part. of shaft 76, suitably stopped at its respectiveends, bears against the bar D and part 81, respectively, and returns shaft 8 and pinions 24 to their working position when the front frame is again lowered.

The substantially vertical seed-duct R, seated in the rear end of the seed-runner or furrow-opener H, communicatesat its upper end with the seed-opening 26 in the base of the seed-hopper and conveys the grain in the case of drilling directly to the furrow-gash made by'the runner H.

In the case of hill-dropping the grain is arrested and discharged from the bottom of the seed-duct R as follows: The vertical arm 27 ispivoted about centrally on pivot 28, seated in the rear extension of the seed-duct R. The lower end of the arm 27 extends a short distance below the seed-duet R and is'pro- Vided atits lower end witha lateral shelf 29, projected across the prolongation of said duct. To the upper end of the arm 27 is pivoted a short toggle 30, which when it is desired to use the machine as a dropper is manually thrown forward against the back of the duct R,as shown in Fig. 2, and holds the shelf 29 A vertical oscillating. lever'3l is also pivoted on pivot 28 and has a forked connection at its upper end to the bracket 59, seated 011 the rock-shaft P. The lower forwardly-projecting end 32 of the lever 31 is adapted to be oscillated between the shelf 29 of arm 27 and the lower end of the duct R- That portion of the lever 31 which passes over the shelf 29, as aforesaid, is preferably closed at three sides, but open at the top and bottom,.so that when said lower end of lever- 31. is thrown forward between the duct R and shelf 29said lower open end 32 forms a prolongation of the duct R to the shelf 29, the open side of end 32'being closed IIO by the vertical portion of arm 27 next above the shelf 29. When at the proper time, through the oscillation of the rock-shaft P, the end 32 is thrown backward, it sweeps or knocks the hill of corn theretofore deposited on shelf 29 to the rear and permits said hill to drop into the earth through the open end 32. The rearward sweep of said end 32 in knocking the corn rearward from shelf 29 counteracts the forward motion of the machine and prevents said motion from carrying the hill of corn beyond the line of the check or cross rows. The movement of end 32 is about the same as the speed of the planter. A forward projection 33 is formed on 32,which when 32 is at the limit of its back stroke closes the lower end of the duct R and prevents any seed escaping therefrom until the end 32 again registers in its forward stroke with the lower end of duct R and permits the corn to pass down to the shelf 29 in position for the next ejection therefrom, as aforesaid.

\Vhen it is desired to drill into the bottom of the duct R, pawl 18 is removed and the gear-rim 22 and seed-plate 23 substituted for seed-plate 15, and when enough grain has been accumulated at the bottom of the duct R to form a hill it is knocked back by the lever 31, as before described.

When the machine is used as a drill throughout, the upper end of the arm 27 is thrown forward and the toggle 3O thrown over backward against the bracket 59 on rock-shaft P, as shown in Fig. 3, which holds the lower end of arm 27 back of the vertical line of the duct R, and the lower end 32 of lever 31 is thrown forward, so as to form a prolongation of the duct R, which permits each grain as it is discharged into the duct R by the drilling mechanism to pass directly into the earth. The machine therefore can be changed almost instantly to hill-dropping from the hopper, drilling from the hopper into the seed-duct, and check-droppin g from the base of the latter, or pure drilling from the seed-hopper to the earth.

Referring to the combined hand and foot lever shown in Figs. 7 and 9, the bell-crank hand-lever 3i is pivotally seated at its angle 35 on the quadrant ll, carriedon the rear end of the tongue 37. The short horizontal arm 38 of lever 3-1; is extended to the rear and pivoted at its rear end to the post 30, the base of which is hinged longitudinally to the lower end 63 of seat-bow 69. The rearwardly-extending foot-lever =l0 is connected at its forward end to the rear end of arm 38 in such a manner as to become rigid with arm 38 in its downward movement, but capable of being thrown forward out of the way of the wire-reel when reeling up. By this means the hand and foot of the driver can be jointly or separately used to elevate or depress the front frame. The ability to operate lever 34: by the foot alone is a great advantage when the hands of the driver are required to control his team. The usual quadrant 4:1 and springpawl l2 may be used to lock the runner-frame in any desired position. The machine is often used with the lever 34: disconnected from the quadrant, when said lever affords means for the driver to force the runner-frame into the ground with his foot when desired. When the foot-lever 40 is pressed downward, the top of post 39 moves forward and downward, passing slightly beyond the line of the pivots 35 and 63, as shown in Fig. 9, thereby locking itself in such position.

The foot-lever 43 furnishes means for dropping the seed independent of the check-rower through the following mechanism: The lever 43 is intermediately pivoted to the quadrant 41 on an independent pivot and has a projection 71 extended below said pivotal seat. To the lower end of 71 is pivoted adjustably the rear end of pitman 72, the front end of which is attached to the crank-arm 73, rising from rock-shaft P. The coiled spring (30 connects the crank-arm 7 4:, formed 011 the lower side of shaft P, to pitman 72 and returns shaft P after each impulse to its normal position.

The check-wire reel 54 is seated on ashaft 55, which projects a short distance beyond its bearings when in position and is provided with the friction-wheels 56, placed at each end of said shaft. In reeling or laying out the check-row wire the reel is supported on the seat-braces 57 in such position that the friction-wheels 56 may be engaged and actuated by the inner one of each pair of wheels G. In order to secure the necessary amount of friction between the wheels 56 of the wire reel and the driving-wheels G of the planter, there are pivoted on the barD short stops or latches 58 in position to be optionally thrown under the bars A in the line of the vertical slots 1 of the plate C, through which the bars A pass. This has the eifect of rendering the two frames substantially rigid,which will prevent the bar D, which is the rear end of the front frame, from rising when downward pressure through the tongue is exerted on the cross-bar B at the front of the front frame.

The lower end of the forwardly-extending seat-bow 69 is bifurcated, the rear bifurcation being adapted to pass down between the transverse bars L L, constituting the axle of the carrying-wheel. The front end of said bifurcation is pivoted at its lower end 63 to the lower end of the post 39. In the rear bifurcation is hung the reversible lock 75, adapted to be turned down upon the bars L L when the machine is in ordinary use and prevent the rear bifurcation of the bow 69 passing down between said bars L L; but when it is desired to increase the friction between the wheels 56 of the reel-shaft and the carryingwheels G of the planter the lock is turned upward in said bifurcation of the bow 69 and the latches 58 of the cross-bar D of the front frame are thrown up under the front bars A. Now when the lever 34: is drawn backward its short arm 38 pushes downward on post 39 IIO and forces the seat-bow 69 downward, the rear bifurcation of bow 69 passing down be tween the bars L L. As the support 57 of the seat-bow 69 is pivotally secured at its lower end to the frame,the downward movement of theseat-bow draws the upper end of the seatsupport forward, and with it the reel-support, and the reel-wheels 56 are thus drawn forward against the carrying-wheels of the machine with a pressure proportionate to the rearward movement of the lever 34.
