I R. COFMAN.
MARKER FOR CORN PLANTERS.
APPLICATION FILED FEB- 24.1919- 1,311,1, TatentedJulyZS), 1919.
THE COLUMBIA PLANOGRAPII co, WASHINGTON, I). c.
RAY COFMAN, 0F BLOOM TOWNSHIP, FAIRFIELD COUNTY, OHIO.
MARKER FOR CO'RN-PLANTERS.
Application filed February 24, 1919.
Z '0 all whom it may concern Be it known that I, RAY COFMAN, a citizen of the United States, residing at Bloom township, in the county of Fairfield and State of Ohio, have invented a certain new and useful Improvement in Markers for Corn-Planters, of which the following is a specification.
This invention relates to that type of marker which is carried on the end of an arm, the arm being pivoted on the rear of the planter frame so as to be shiftable from one side of the planter to the other. The object of the invention is to provide improved means for shifting the marker over without using the hand.
The invention is embodied in the example herein shOWn and described, the features of novelty being finally claimed.
In the accompanying drawing- F igure 1 is a plan view illustrating the means as applied to a planter.
Fig. 2 is a vertical sectional view on the line II--II Fig. 1 looking up. 7
Fig. 3 is a diagrammatic view illustrating the principle involved.
In the views 5 designates the frame of the planter, said frame being supported by suitable carrying wheels 6 as usual.
7 designates a shaft suitably journaled longitudinally on the frame said shaft having aflixed to its rear end one end of the marker arm 8 carrying at its other end the marker 9. Secured on the shaft 7 is a beveled gear 10. Engaging the bevel gear 10 is a similar bevel gear 11 having a crank shaft 1:2 journaled in the frame, a supplemental piece 18 being added to the frame to support one of the ends of the crank shaft.
14: designates the drivers seat. The gears 10, 11 and crank shaft 12 are so located as to be within operative range of the drivers foot and so that the driver can exert considerable weight upon the crank or sufficient to raise the marker arm to nearlyvertical position. The momentum of the rising arm will carry it beyond the vertical toward the opposite side of the planter. When the marker arm thus passes the vertical it is important that its fall be resisted otherwise it might be broken. To provide for this the gears are so proportioned to each other that when the marker arm is in vertical position Copies of this patent may be obtained for Specification of Letters Patent.
Patented July 29, 1919.
Serial No. 278,621.
the crank is at or about at its most depressed position hence when the marker arm is falling from the vertical the crank is rising and against the rising crank the driver again imposes his weight and thereby resists undue rapidity in the descent of the marker.
The diagram Fig. 3 illustrates substantially proper relative positions of the marker, operating crank and gears. In this view the parts are designated the same as before except that the bevel gears which are here represented in spur gear form are designated 10 and 11 lVith the construction as herein described it is unnecessary for the driver to let go of the reins to shift the marker.
The forms of the parts can be changed without departing from the invention as claimed.
lVhat I claim is:
1. In a corn planter the combination of a marker arm and a rotary shaft on which the marker arm is fixed, a foot-operated crank shaft, and gears connecting said shafts, said gears arranged and proportioned with respect to each other as to require movement of the crank downward and beyond a vertical plane coinciding with that of the crank shaft to shift the marker from either side of the planter to the other, substantially as described.
2. In a corn planter the combination of a marker arm and a rotary shaft on which the marker arm is fixed, a foot-operated crank shaft arranged at right angles to the marker shaft, and gears connecting said shafts, said gears arranged and proportioned with respect to each other as to require movement of the crank downward and beyond a vertical plane coinciding with that of the crank shaft to shift the marker from either side of the planter to the other, substantially as described.
3. In a corn planter, the combination of a marker arm and a rotary shaft on which the marker arm is fixed, a foot-operated crank shaft and gearing between the shaft of the marker arm and the crank shaft to cause the vmarker arm to rise when the crank of the crank shaft is depressed and to cause said crank of the crank shaft to rise when the marker arm falls.
RAY GOFMAN.
