CH ECK-ROW GORNQ/PLANTER.

SPECIFICATION forming part of Letters Patent No. 522,381, dated July 3, 1 894.

' Application filed March 18,1893. Serial No. 466,689. a. model.)

To all whom it may concern: 7

l 3e it known that I, GEORGE E. MCGINNIS, a cltlzen of the United States, residing at Oisco, 1n the county of Piatt and State of Illinois,

have invented certain new and useful Im-" drawings, and to the letters and figures of ref erence marked thereon, which form a part of this specification.

My invention consists in certain new and" valuable improvements on the corn planter for which Letters Patent No. 426,947 were granted to me April 29, 1890; and my invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective view of my improved corn planter. Fig. 2 is a rear elevation thereof. Fig. 3 is a side elevation of the front half of the planter. Figs. 4,5, 6 and 7 are a detail views, which will be hereinafter described.

The same letters and numerals of reference indicate corresponding parts in all the figures.

wheel frame, upon the rear part of which the drivers seat is mounted. The forwardly-projecting side-beams of this frame are formed in two sections or parts, B and B and to their forward ends the frontcross-beam O of the runner frame C is hinged, as shown, to enable the said frame, whichcarries the seedboxes and seed-dropping mechanism, to be the runner'frame C is free .to move on its front hinges, that when the lever D is drawn back to In the drawings,"B indicates the rearorraise the runner frame the shoulders 3 will lock against the parts 2 and the beams will be held straight and rigid, thus facilitating the raising of the rear end of the hinged front frame by the lever D; while the weight of the driver can thus be utilized, owing to this rigid interlocking of the beams, to take the weight ed the front of the planter andthe horses necks, while turning around at the end of a row, and in going from one field to another.

4, 4, indicate curved metal castings, one of which is bolted beneath the front end of the front or runner frame 0 at each side thereof. These metal castings are each for-med at the point shown with a curvedslot, 5; and the front end of the runner A is secured to the casting by a bolt, 6, passing through the said end and the curved slot of the casting. It will be'seen that by using this casting the runner need not be of just such a length to be fitted on, as the curved slotted casting will enable runners of slightly different lengths to vbe employed, which is a decided practical advantage.

7 indicates the axle, which revolves with,

one of the covering-wheels,b, fixed upon it, while the other covering-wheel, b? fits loosely upon the axle and has a clutch-section, 8, on the inner end of its hub, and is normally pressed into engagement with a fixed'clutchsection, 9, secured to the revolving axle, by the pressure of the spring 10, which is mounted on the outer end of the axle as shown, to facilitate the turning of the planter at the end "of a row.

ral spring, 14. A sprocket-chain, 15, passes around this wheel, 11, and the sprocket pinion Z on the shaft L; and this shaft L is thus revolved, and the seed dropped from the seedboxes down into the seed'spou'ts by the mechanism which was described in detail in my Patent No. 426,947 before referred to, and

which it is therefore not necessary to here describe in detail.

16 indicates the pivoted foot-lever,which engages with the collar of the clutch-sleeve of sprocket-wheel 11 as shown, whereby the sprocket-wheel can be thrown out of gear, when turning around at the end of a row, or when driving from fieldto field.

17 indicates the second dropper shaft, which is mounted in bearings at the rear end of the runner frame 0, and has a sprocket-pinion, 18, keyed upon it, around which passes the sprocket-chain from the sprocket-wheel 7c of the shaft I this shaft being operated by the check-row cord as described in detail in my above specified patent, No. 426,947. The outer ends of the drop-shaft 17 are provided with small crank-arms, 19, 19, to which are pivoted the upper ends of lever- rods 20, 20.

The-lower ends of these rods pass through the slotted, outwardly-bent, upper ends, 21, of the stems of small sliding doors, or valves, 22, which are arranged as shown in bearings to control the openings at the lower ends of the seed-spouts A. The lower extremities of the rods 20 are provided with keys, 21", to prevent their pulling out of the slotted ends 21. It will now be seen, that as the shaft I is turned by the check-row cord as the planter is driven forward, that the drop-shaft 17 will be turned, and through its cranked end-arms and lever-rods 20 will move the slide-doors 22 up and down at each stroke of the pawl-lever J, as the latter is actuated by the successive buttons on the check row cord which passes through its forked end in the usual manner, thus dropping the seed into the furrow at the exact points desired.

It will be seen that by my invention the feed of the corn or seed from the seed-boxes down into the seed-spouts is effected by one set of mechanism, while the discharge of the seed from the lower ends of the spouts into the furrows is controlled by an entirely separate mechanism.

The rim of the sprocket-wheel 11 is of such width that a double series of cogs or teeth, 11, are formed upon it, one of which is engaged by the sprocket-chain 15, which runs to the pinion on the shaft L, while a second sprocket-chain, 24, passes around the other series of teeth of wheel 11 and thence around a pinion 25 secured on the drum-shaft, E. This shaft is mounted and turns in bearings, E, on the seat arch or frame E, below the drivers seat, as shown; and upon it is loosely mounted the drum, E upon which the checkrow cord is wound. The left-hand end of this drum bears against a small fixed collar 0 on the shaft E, while at its other end the shaft to bear against the drum, the drum will revolve with the shaft E or the friction may be so adjusted that the drum will only turn when a certain amount of poweris applied to the periphery thereof. The threaded part of the shaft is provided with a longitudlnal slot 6, and the tension-sleeve has an open ng through which a key, f, is passed, running through the slot of the shaft, to hold the sleeve from turning on the shaft after it has been screwed up to the desired point.

The rear cross-beam, 27, of the wheel frame B has its ends extended, and to these extended ends, directly back of and in line with the covering wheels I), b, are movably secured the scrapers, 28, 28. The scrapers are pivoted near one end, at, 29, to the extended ends of bar 27, with aheaded bolt, 30, passing through slots, 31, in their inner rear ends, as shown in Fig. 5, and are formed with the curved or rounded forward parts 32. Connecting rods, 33, connect the inner ends of the scrapers pivotally with the lower ends of foot-levers 34, which are centrally pivoted as shown within easy reach of the drivers feet. It will now be seen that by pressing down the upper ends of the foot levers, the pivoted, slotted, scrapers will be swung forward so that their curved forward part will scrape the dirt away which accumulates in the concaved covering-wheel s; and by raising the curved upper ends of said foot-levers with the toe after they have been thus depressed the scrapers are slid back out of the way; and can thus be used as frequently as required.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut is-- 1i In a check-row corn-planter, the combination, with the supporting frame, of the seed hoppers provided with devices for dropping the seed into the seed spouts, the shaft 17, geared to the sprocket-wheel of the front shaft I and having the small crank-arms at its ends, the vertically reciprocating valves controlling the openings at the lower ends of the seedspouts, and connections between said valves and the crank-arms of the shaft 17 substantially as set forth.

2. In a corn-planter, the combination, with the supporting frame, the seed spouts and the runners, of the curved slotted castings 4, and the securing bolts passing through the forward ends of said runners and the curved slotted castings; substantially as set forth.

3. In a check-row cornplanter, the combi nation, with the supporting frames, of the axle having the fixed covering wheel and the fixed clutch section 13, the loose sprocket wheel having the clutch-section 12 adapted to engage with the fixed section 13, the coiled spring bearing against the loose sprocketwheel and the foot-lever adapted to throw said wheel out of gear, the shaft L operating the seed-dropping mechanism at the bottom of the hopper, and geared with the sprocketwheel on the axle, the valves controlling the openings at the lower ends of the seed-spouts,

and the shaft 17, having the crank-arms conneoted with said valves and geared with the forward shaft which is operated by the check: row cord; substantially as set forth.

4. In a corn-planter, the combination with the covering-wheels of the movable scrapers having the curved forward part, pivoted near one end, formed at the other end with a slot through which a headed bolt passes, the pivoted foot-levers, and connections between said levers and the pivoted bodies of said scrapers; substantially as set forth.

5. In a check-row corn-planter, the device for winding up the check-row cord consisting of the shaft, mounted in raised bearings, having the fixed collar, and geared to the revolving axle, said shaft having the threaded part formed with the longitudinal slot, a drum loosely mounted on the central part of'the shaft, and the internally-threaded tension said opening and the slot of the shaft; substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses. GEORGE R. MOGINNIS. Witnesses:
