This invention relates to a marker. More specifically it relates to a control for a marker and to supporting structure for the marker and for the control.
Markers are known that involve a pair of markers interconnected by a flexible element so that the placing of one marker in lowered ground-engaging position brings about the placing of the other marker in raised inoperative position. It is desirable to have a simplified control for such a marker construction, so that the shifting of the markers between operative and inoperative positions may be effected as easily as possible. Quite frequently this is accomplished by applying force directly to the markers themselves to shift them from one position to another, and, in some in-- stances, there is a separate control for each marker. The present application has to do with a simplified control for shifting the markers and with supporting means for the marker and for the control.
An object of the present invention is to provide an improved marker.
A further object is the provision of an improvement in a marker construction involving apair the one marker and raise the other marker. The flexible element interconnecting the markers passes upwardly and over the frame structure, and is supported in guides on the upper end of uprights'secured to the frame structure.
of the present invention, the section being taken of interconnected markers arranged so that the placing of one marker in lowered ground-engaging position brings about the placing of the other marker in raised inoperative position.
A further object is to provide an improved control for a marker.
A still further object is the provision of a control for interconnected markers arranged as described above.
Still another object is the provision of an improved mounting structure for a marker.
Another object is to provide an improved mounting for a control means for a marker.
Other objects will appear from the disclosure.
According to the present invention, markers mounted at opposite sides of a frame structure of a planter or other implement are interconnected by a flexible element which assures that the placing of one marker in ground-engaging position will effect the placing of the other marker in raised inoperative position. A control element is connected with-a mid-point of theflexible element interconnecting the markers and extends along the flexible element and then forwardly to the front of hitch structure connecting the planter or like implement to a tractor. A forward pull upon the control element exerted at its forward end adjacent the tractor serves to raise one marker and lower the other marker, and another similar forward pull serves to lower short,

. Figure 4 is a side view, partially in section, of the planter and the novel marker arrangement, the section being taken on the line 4 of Figure 3; and
Figure 5 is aside view of a front portion of the planter and a rear portion of the tractor.
The reference character In designates a planter which comprises a plurality of planting units I l and a plurality of fertilizer units l2. The planter also includes -a framestructure comprising a pair of long, transverse members l3 and a pair of longitudinal members M. The frame structure is supported upon wheels l5 by'means of axles l6, depending brackets l1, and short, longitudinal members l8 secured to the transverse members l3. Positioned above the frame structure, made up of the transverse members l3 and longitudinal members I4, is a long, transverse beam I9, upon which is mounted by brackets 20 theplanting units II. The fertilizer units l2 are mounted upon the rear, transverse member l3 by means of brackets 2!. The transverse beam i9 is held in spaced relation above the framework by means of a pair of uprights 22 secured to the short, longitudinal members H! at opposite ends of the frame structure, braced by pieces 23. The uprights 22 extend a considerable distance above the frame structure and carry at I their upper ends guides 25. The uprights 22 de- ,pend somewhat below the frame structure and carry at their lower ends pieces 26. In pivotal relation through each piece 26 there extends a bent end 21 of a rod 28 adjustably telescoping within a tube 29. The tube 29 may be fixed in a plurality of positions with respect to the rod 28 by a pin 30 extending through any one of a plurality of holes 3| in the tube 29 and in any one of a plurality of holes 32 in the rod 28. The rod 28 and tube 29 constitute a marker arm 33, at
the outer end of which on the tube 29 is carried a marking element 34. The spacing of marking element 34 from the side of the frame structure 4 ber 31, a plurality of openings 40, through which the bolts 36 may extend. Secured to the angle member 35 is a bent part 4! which extends in pivotal relation through a piece 42 secured to the front transverse member l3, and serves pivotally to connect the brace 35 to the frame structure. A bent piece 52 secured to the angle member 3? and a bracket 43, through which the bent piece 42 extends and which is secured to the tube 29, serve to connect pivotally the marker arm 33 and the brace 35.
The marker structure just described is the same upon both sides of the planter Ill. As seen in Figure 1, the arrangement is such that, when the one marker arm 33 is down and the marking element 34 mounted thereon is in ground-engaging position, the other marker arm 33 is up and the marking element 34 carried thereon is well away from the ground. The marker structures are interconnected by a flexible element 44 connected to brackets 45 secured to the tubes 29 of the marker arms 33. The flexible element 44, as viewed in Figure 1, extends at an angle to the vertical upwardly and transversely of the frame structure to and through the guide 25 on the lefthand upright 22, then horizontally and transversely to and through the guide 25 on the righthand upright 22, and then to the right-hand marker structure. Positioned at the middle of the frame structure is an upright 46 secured at a point somewhat below its mid-point by a bolt 41 to the transverse beam I9. The lower end of the upright 46 is secured to one of a pair of centrally located draft members 48 by means of a plate 49 and bolts 50. A pulley 5| is pivotally carried on a U-shaped part 52 secured to the upper end of the upright 46. The upright 46 serves incidentally to support the middle of the transverse beam l6. Connected to a mid-point 53 of the flexible element 44 is a flexible element 54 extending transversely of the planter I and generally along the flexible element 44 to and around the pulley and then forwardly above the draft members 48 which extend considerably forwardly of the planter l0, and in particular its frame structure. ,The forward end of the flexible elewhlch extends through .the upper end of an upright 56 carried on the forward end of the draft members 48 and terminates in a loop 51, as shown ment 54 is connected to a stiff wire element 55,
in Figure 5. A hitch member 58 secured to the 3 forward ends of the draft members 48 is connected to a draw bar59 of a tractor 60 having an operator's seat 6 l.
The loop 51 may be engaged by an operator on the operator's seat 6| of the tractor 60, and a forward pull may be exerted thereon. 'This forward pull will be transmitted through the wire member 55 of the flexible element 54 to the midpoint 53 of the flexible element 44. Sincethe portion of the'flexible element 54 immediately adjacent the point of connection 53 of the flexibleeiejment 44 extends transversely, the pull or Jerk upon the loop 51 is effective to move the point of the connection 53 transversely toward the guide pulley 5|. This causes the left-hand marker structure of Figure 1 to move upwardly from the full line position toward the dotted line position and the right-hand marker structure to move from full line position toward the dotted line position. If the pull or jerk is sufficient, the point of conrfection 53 will move beyond the guide pulley 5| to the dotted line position of this point shown in Figure 1. Thus, the left-hand marker structure will have, in effect, changed positions with the right-hand marker structure and so the marker which was originally up will be down, and the marker structure which was originally down will be up. When it is de sired to return the marker, structures to the full line position of Figure l, a similar forward pull or jerk upon the loop 51 of the wire rod 55 causes the point of connection 53 to move toward the left to the guide pulley 5i and beyond to its original position, and the markers will have been returned to their original positions.
From the foregoing description it will be evident that there have been provided a new and novel control for a marker structure and a new and novel mounting for the marker structure and for the control thereof. In so far as control of the marker structure is concerned, it is believed to be new to provide a control means which operates by one Jerk or pull toshift the markers from one set of extreme positions to another set of extreme positions and a second similar pull or jerk returns the markers to their original set of positions. This takes place, because a portion of the control means extends laterally and transversely from a guidegenerally along the flexible element interconnecting the markers. As far as the mounting of the marker structure and the control means therefor is concerned, it is believed to be new to provide uprights which carry at their upper ends guides for the marker interconnecting element and at their lower ends, pivots for the marker arms. It is believed to be new to provide in a centrally positioned upright carrying a guide for the'control means and an upright positioned on the forward end of a draft means for a planter .and serving as a guide for the forward end of the control means adjacent the tractor pulling the planter. The frame structure and the carrying of the planting elements upon a transverse beam spaced above the frame structure are believed to be new, but this is claimed and shown more fully in the applicant's co-pend- The intention is to limit the invention only within the scope of the appended claims.
