Application filed June 10, 1905. Serial NoY 264.732.

To all whom it may concern:

Be it known that I, LAFAYETTE IVI. MCCOR- MAc, a citizen of the United States, residing at Mallard, in the county of Hancock and State of Illinois, have invented a new and useful Improvement in Corn-Planters, of which the following is a specification.

My invention relates to improvements in corn-planters, and refers more particularly to the markers for corn-planters.

The object of the invention is to provide a device which will dispense with the use of the check-row wires commonly used to give perfect alinement to the hills of corn and also to provide a marker attachment whereby as each hill is dropped a mark will be made in the ground, so thatthe driver may readilyY aline his rows.

With these and other objects in view my invention consists of a corn-planter having marker attachments carried by the runners or furrow-openers thereof, means operated from the driving-axle for operating said marker, means for causing the marker to engage the ground at definite intervals, means for throwing the planter mechanism into or out of gear, and means for operating the marker independent of the main axle.

My invention further consists in certain other novel features of construction, combination, and arrangement of parts, substantially as disclosed herein.

Figure 1 is a top plan view of my improved corn-planter, showing the markers and connections. Fig. 2 is a side elevation of the complete machine. Fig. 3 is a rear end elevation of the same. Fig. 4 is a detail view of the drop and marker mechanism, taken on line 4 4 of Fig. 1. Fig. 5 is a detail view of the operating-head, and Fig. 6 is a detail view of the marker and runner taken from the rear and a detached view of the markersleeve.

Referring to the drawings, the numeral 1 designates the main frame of the machine, in which is journaled the axle 2. Groundwheels 3 are mounted upon the ends of the axle, one being rigid with respect thereto and the other loosely mounted on said axle. These ground-wheels are formed withl the separated concaved fellies 3, which by their shape are adapted to close the furrow 'and pack the earth after the corn has been deposited therein.

A clutch-disk 4, having ratchet-teeth 5, is

4 19 in the segment-plate.

fixedly secured on the axle, and a sleeve 6 is loosely'mounted on the axle and carries on one end the clutch-disk 7, adapted to coperate with the fixed clutch-disk. Near the other end of the sleeve is secured the sprocketwheel 8, and adjacent said sprocket-wheel is the ratchet-wheel 9. A lever 10 is loosely mounted on the sleeve between the two wheels and carries a dog 11, adapted to engage the teeth of the ratchet-wheel. A shifting rod 12, pivotally secured at its `front end to the cross-bar 13, engages the shouldered end 14 of the sleeve. A Spiral spring 15 is mounted on the axle engaging the shouldered end of the sleeve and tends to normally hold the clutch-disks in operative engagement. A segment-plate 16 is secured to the rear end of the frame, and pivotally secured to said plate is the operating-lever 17, provided with a spring-actuated dog 18 to engage notches A right-angled pin or extension 20 is secured to the lower end of the lever 17 and engages the rear end of the shifting-lever, so that by means of the lever 17 the mechanism may be thrown into or out of gear.

A pair of vertical standards 21 are mounted upon the frame and support a seat-bar 22. Aseat-post 23 is secured to the cross-bar 13 and carries on its upper end the drivers seat 24. Secured to the bar 22 is the guide-rod 25, which is adapted to form a keeper for the lever 10. Stakes 26 are pivotally secured to the standards by bolts 27 and are formed with notches or recesses 28 in their lower ends. Flat springs 29, secured to the frame, are provided on their free ends with the lugs 30, adapted to engage the notches inthe lower ends of the stakes and hold said stakes in an upright position. These stakes are for the purpose of assisting the driver to plant a straight row, as by sighting over the stake and runner or frame to a stationary point he is materially helped in the proper alinement.'

I provide a runner-frame comprising front IOO or furrow openers or shoes 31, secured toto the foot of the runner, through which the corn travels and is deposited in the furrow opened by the runner.

A counter-shaft 37 has its ends journaled in the hoppers and operates suitable dropping means therein. (Not shown.) Loose'ly mounted upon said shaft is the main or driven vsprocket-wheel 3S and the fixed or rigid driving sprocket-wheels 39. sprocket-wheels 39 are provided with hubs 40, which abut against the inner walls of the hoppers to hold the shaft against lateral movement. A.sprocketchain 4l connects the sprocket-Wheel 8 on the axle with the driven sprocket-wheel 3801i the countershaft, and the chain-guard idler or bracket 42, carried by the frame, embraces the lower side of the chain and keeps it at the proper tension. j

Marker-shafts 43 are j'ourn'aled in rearward extensions 44 of the runners and carry on their inner ends sprocket-wheels 45, operated bv chains 46 from the driving sprocketwheels 39 ony the counter-shaft. On the marker-shaft adjacent the sprocket-wheel and on the opposite end of said shaft are mounted the markers 47. I have shown these markers as formed with flat pointed ends; but they may be of any other suitable or desirable form. The portion of the runner through which the marker-shaft extends is recessed, as shown at 48, and upon said shaft` within the recess is mounted the collar 49. A pin or key 50 is secured to the shaft and engages the longitudinal slot 51 in the collar, so that the collar may have a sliding rotary motion on the shaft. One end of the collar is of irregular shape and provided with a seat or recess 52, and a complementary wedgeshaped projection 53 is formed in the wall of the hopper adjacent the distorted end of said collar. A spiral spring 54 on the shaft exerts its tension upon the collar and causes the distorted end of the collar to engage the wall of the hopper. Thus as the marker is rotated it is also given a lateral movement, which causes it to make a readily-distinguishable mark in the earth. Guard rollers or idlers 55 are secured to the yoke of the runner-frame and keep the sprocket-chains 46 at the proper tension.

A standard 56 is mounted upon the yoke, through which the counter-shaft passes, and on said standard below the shaft at 57 is pivoted the irregular-shaped leverarm 5S, formed with the lower extension 59, which is adapted to be contacted by the pin or extension 60 on the rim of the trip-wheel 61, said wheel being loosely mounted on the shaft, but rigidly secured to the driven sprocket 38 by the lugs or pins 69. Pivotally secured to the upper end of the lever 58 is the weightarm 62, provided on the end with a ball or other weight 63. To the weight-arm below the point of connection with the lever-arm is The pivoted the pawl 64, which is adapted to engage the teeth or lugs 65, formed'iin the periphery of the wheel 66, said wheel beingrigfollows: The driven sprocket on the countershaft revolves directly with the drivingsprocket on the axle and carries with it the trip-wheel 61. The pin or extension 60 on the trip-wheel engages the lower end of the lever-arm, which is raised, carrying with it the weighted arm. The pawl on the weightarm engages the teeth of the xed wheel 66, thereby causing a partial rotation of the counter-shaft. The counter-shaft by this partial rotation causes the dropper mechanism to operate and causes a complete revolution of the markers, thereby marking the hills of corn just dropped. After the leverarm has been lifted sufficiently to allow the pin on the trip-wheel to clear the lower end of the arm the weighted arm causes the lever to fall back into the first position, and the same operation is repeated. Upon starting the machine or at any other time the position of the markers may be advanced by partially rotating the ratchet-wheel on the axle by means of the operating-lever 10. A tongue may be attached to the runner-frame in the ordinary manner, or the planter may be operated by mechanical power.

From this description, taken in connection with the drawings, it will be evident that I have accomplished all the objects herein set forth and provided a corn-planter which is entirely practical and efficient and greatly to be desired.

I claim-` 1. In a corn-planter, the combination with i the runner-frame and dropper mechanism therein, of markers mounted on journals in the runners and connected by chain and sprocket to the dropper mechanism, and adapted to be operated at regular intervals.

2. In a corn-planter, the combination with a runner-frame, markers journaled therein, of a counter-shaft carried by the frame, and chain-and-spro'cket connections between the counter-shaft and markers.
