LAND-MARKER FOR CORN-PLANTERS.

Application filed January 31, 1912.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, \VILLIAM R. 0001;, a citizen of the United States, residing at Streator, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Land-Markers for Corn-Planters, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in land markers for corn planters, and has for its object to provide improved means whereby the marker may be raised from one position preparatory to turning around at the ends of the field, swung around and laid down on the opposite side of the planter after the turn is made.

Another object of the invention is to provide a novel folding arm which can be folded into compact form and carrying a marker disk on the outer end thereof.

Another object of the invention is to provide novel means whereby the arm carry ing the marker disk will be titled to various angles when in use on a side hill.

A further object of the invention .is to provide a land marker for corn'planters which will possess advantages in points of efliciency and durability, is inexpensive to manufacture, and at the same time is simple in construction and operation.

With the above and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts hereinafter more fully described, pointed outin the claims and shown in the accompanying drawings in which,

Figure 1 is a rear elevation showing the marker arm extended to an operative position. Fig. 2 is a similar view showing the marker arm folded into a compact form. Fig. 8 is a top plan view. Fig. 4 is a sectional view on, the line 44, Fig. 2, Fig. 5 is a sectional view on the line 5-5, Fig. 2, and Fig. 6 is a sectional view on the line 6-6 of Fig. 2.

Referring more particularly to the drawings, 1 indicates the rear cross bar of a corn planter, having a pivotally mounted bar 2 secured thereto by means of the bolt 8. Mounted on the bolt 3. and disposed on the rear of the bar 2, is a U-shaped member 4 which is held against relative lateral move ment by means of the screws 5. The inner end of the supporting arm 6 is pivotally secured between the arms 7 of the member 4, said supporting arm being adapted to swing in a substantially horizontal plane.

A semi-oircular supporting member 8 is provided having its ends flattened and bent at right angles to the body portion and secured to the bar 2 by means of the small bolts 9. This member-8 is to provide a support for the arm 6 while it is being swung from one side of the planter to the other. The outer end of the arm 6 is formed hookshape, as shown at 10, and the

arms

11 and 12 are secured thereto by means of the bolt 13. The arm 12 is rigidly secured to one side of the hook 10 and disposed in a substantially inclined position, and the arm 11 is pivotally secured on the other side of the hook 10.

Pivotally secured to the outer ends of the

arms

11 and 12 is the folding marker arm 14 in the form of a lazy tong. These

arms

11 and 12 and the folding arm 14 are to be made of iron so they will be strong and durable. A rotatable marking disk 15 is mounted on the outer end of the arm 14 and adapted to mark off the rows when the pla'nte'ris crossing the field. A pair of spaced arms 16 are secured to the disk 15 and adapted to be adjustably secured to the outer end of the arm 14 by means of the bolts 15. The outer end of the arm 14 is provided with a plurality of spaced openings 16 so that the disk 15 may be adjusted to difierent widths of rows. desired. A curved rack bar 17 is provided having one end secured by means of the bolt 13 and the other end secured by means of the bolt 18. A ratchet lever 19 is pivotally mounted on the bolt 13 and disposed adjacent the rack bar, said lever carrying a springpressed pawl adapted to engage the rack bar to hold said lever in an adjusted position. A short bar 20 is secured to the lever and the inner end of the arm 14, whereby the arm 14 may be unfolded or folded, as desired.

Suspended from the bar 2 at each end thereof, are the hooks 21 adapted to engage with the underside of the bar 1 when the disk 15 is raised from the ground and prevent the arm from dropping down. These hooks are also convenient when planting on the side hill as they will allow the marker arm to raise or lower, as desired.

By having the bar 2 pivotally mounted, the arm 14 will raise or lower when the disk 15 strikes a large stone or other obstruction, thus preventing the arm from being wrenehed at its inner end, as is usually the case where the arms are rigidly secured.

This marker can be quickly and easily attached to any corn planter, and the marker arm can be readily and easily folded when turning around at the end of the field. While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction, and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope thereof.
