rear end of which has a perforated bracket 10, through which extends a curved rod 11, the upper end of which is pivotally connected with the arm 6 of the lever and the lower end of which is provided with a tightening-nut 12 for the purpose of regulating the tension of a spring 13, which is coiled upon the rod 11 and exerts pressure in adownward direction upon the bracket at the rear end of the frame for the purpose of elevating the front end of the latter and taking weight off the necks of the draft-animals and also assisting in the ad.- justinent of the runner-frame when the latter is to be raised at the ends of the rows.

Beit known that we, JOHN W. BARNETT and MORTON SANDERS, citizens of the United States, residing at Monmouth, in the county of lVari-en and State of Illinois, have invented a new and useful Marking Attachmentfor Corn- Planters, of which the following is a specificatio'n.

This invention relates to land markers, such as are used,.for instance, in connection with corn-planters for the purpose of laying out or marking the land as the machine progresses for the purpose of guiding the driver or operator upon the return trip; and it has I 5 for its object to simplify and improve the con- The operators or struction and operation of this class of deported upon a tripod, two members of which, vices. 15, are connected with the side members of With these and other ends in view, which the wheel-frame, the third member being exwill readily appear as the nature of the intended forwardly and connected with the shaft vention is better understood, the invention 4, upon which the hand-lever is fulcrumed. consists in the improved construction and The seat-supporting member 16 has a quadnovel arrangement and combination of parts, rant 17 attached thereto for engagement with which will be hereinafter fully described, and a stop member 18, connected with the handparticularly pointed out in the claim. hand-lever 5, which latter may be thereby re- 5 In the accompanying drawings has been tained at various adjustments.

Upon the side members of the wheel-frame Corresponding parts in the several figures 1, near the rear end of the latter, is supported are indicated throughout by similar characa cross-bar 25, which is connected with said ters of reference. side members by means of hook-bolts 26 and he main frame or wheel-frame 1 of an ornuts 27. The cross-bar carries an approxidinary corn-planter has been shown as being mately semicircular arch-bar 28, which may provided upon the sides thereof with bracket be constructed of round iron, the ends theremembers 2 2, supporting at their lower ends of being firmly attached to the cross-bar 25. the shaft or axle 3 and at their upper ends a The rear cross-bar 29 of the frame 1 has been transverse shaft 4.

The stud 32 has a head 35, which is provided with a slot 36, in which is pivoted the marker-stat? 37, which latter is provided at its outer end with a ground-engaging shoe 38, which may be of circular form, as shown in the drawings, although any suitable form of shoe will answer the purposes of the invention. Suitably connected With the fixed point of the marker-staff is one end of a chain 39, the other end of which has a ring or link 40 loosely engaging the arch-bar 28. Likewise connected with the marker-staff at or near the point of attachment of the chain 39 is one end of a flexible member {LL which is guided over the pulleys 22 and 23, the free end of said flexible element being attached to the rod 20 near the front end of the latter or to any other suitable fixed point. ous that the flexible member 41 is to be of such a length that it may serve to support the marker in ground-engaging position when the corn-planter with which it is connected is traversing the field.

When the machine is to be turned at the end of the row, the hand-lever is manipulated to elevate the rear end of the tongue, together with the runner-frame, thus depressing the rearward-extending arm 7 and manipulating the flexible element 41 so as to elevate the marker-staff to the position shown in dotted lines in Fig. 1, thus enabling the machine to be turned and placed in position for the return trip, when by again manipulating the hand-lever 5 the tongue and the runner-frame will be restored to operative position. The same will be the case with the marker-staff, provided that the first operation of the lever 5 was accomplished with sufficient force to swing the marker-staff across its pivotal center; if not, it may be found necessary for the operator to move it slightly by hand in order to cause it to descend at the proper side of the machine. The chain member 39 by engaging the arch-bar 28 not only marker-staff with relation to said arch-bar, but its length may also be so adjusted as to It is obviserves to guide the I support the marker-staff in operative position, thus at all times relieving the flexible element 41 of the strain caused by the weight of said bar.

The marker-staff 37 being connected pivotally with the supporting-pivot 32 at an angle to the axis of the latter will at all times swing clear of the drivers seat, its movement with relation to the planter-frame being practically of a universal character.

This invention, as will be seen from the foregoing description, is simple in its nature, and it may be easily and effectively applied to check-row corn-planters of ordinary construction.

Having thus described the invention, what is claimed is- A planter-frame, a seat-supporting tripod upon said frame, a cross-bar connecting two of the seat-supporting members, a bracket connected with the third seat-su pporting mem her and extending rearwardly through said cross-bar, a quad rant securely connected with one of the seat-supporting members, a handlever supported concentric with said quadrant and having a stop engaging the latter and a rearward-extending arm, a marker-staff connected pivotally with the ley supported at the free end of the bracket member, a flexible member connected with the marker-staff and guided over said pulley to a fixed point of attachment, and a guide-pulley connected with the rearward-extending arm of the hand-lever and engaging said flexible element intermediate the guide-pulley at the free end of the bracket and the fixed point of attachment.

In testimony that we claim the foregoing as our own we have hereto afiixed our signatures in the presence of two witnesses.
