Kriegbaum, Richmond, Inci assignor to International Harvester Company, anorporation of New Jersey Applicatibh November 8, 1943, Serial N0. 509,420 8 Claims. (GI. 97-230) 4 This inventlon relates to.amarker for plantrs. More specifically, it. relates 1:0 a. marker construction in which the ground-engagingkmd furroW- makingelement is constructed for maximum flexibility on turns.

In the use of markers .for planters, particularly in tractor operation, generally an independent marker isused on ea.ch side c f the tractor TIhe marker anditscarrying structure arenot always .raisec1 toinoperative position ab the moment the turn is started. As the dperativ marker is a-lways -011 the unpla.nted side, the turns are always made in t;he direction of the grox'1nd-engaging marker. As the tractor is of a comparativelyshort wheel base, the marker extending laterally from the tractot actua1ly moves rearwarclly during the turrn With the conv'entional disk marker or the scraper or shove1 typef'of marker, there is a tendency for the marker to be pushed into the ground and cause undesirabl'e throwing up of the seil or digging of holes. The present invention rela.tes to a marker construction in which the furrow-making element is mounted for a folding-up movement when moved in a rearvvard direction and which also is shaped to ride the surface of the soil without 'making a furrow whenmoved in a rearward direction. 'I'he principal object, thereforie, .of the prese11t; invention is to proVide an improved furrow-m'aking element for a marker device for planters.

In the drawingr Figure 1 is a diagrammatic drawing showing a portion of a, planter withthe furrow-marking structure of the invention embodied therein;

Figure 2 is a perspective of t.he outward end of Ing wheel II, is diagrammatically illustrated to Show nthe ma.nner in which the markar structure 01' the invention may be used. Said planter also shows a..pair of seed can's I2 and uprights I3 for suppnrting the marker raisixig andlowering element.

'Ihe structure for snpporting the marker includes one member I 4 in the formof a. hollow pipe and a. diagonal bracepipe I5 Connected t the pipe I4 by a clamp I6. Both of the pipes are connectied to the frame structure II) of the planter b'y.fleXible connections in th'e form of eyes and loops, one of w'hich is illustrated a1; I'I in Figure 1. A Connecting eye I8 on the pipe I4 pr ovides means for connecting a flexible marker raising am1 10Wering element I9. Said, element passes over a pulley 20 and across to the ooher side cf the planbar. Asecond fiexibleelement 2I, which may be a chain, rope, or cab1e, is connected to the element; I9 at 22 extending ov.er a. pulley 23 and downwxrdly where it may be connectecl to a.ny suitable lifting and lowering means.

A bracketmember 24 is clamped near the outer end of thepipe I4 by means of two spaced up-. w3rdly extending ears 25 and a 10011226. Said member, in addition to a, body portion 21 surrounding the: pipe, includes outwardly anal downwardly projecting extensions 28, which are spaced fyom each other and-connected ab their outer ends .by a transverse portion 29.

A marking element 30 formed of high carbon stee1, similar 120 spring steel, is provided a1: its

upper end With a. cy1inder portiou 3I, which forms a Journal for pivotally mounting the eler ment on the projecting end cf the pipe I4. The

element p'rojects downwardly through the space formed between the extensions28 an the bracket mernber 24. The transverse portion 29' on sai d extensionis 28 to allow .free movement cf the 1 element 30. Said element 'is fitted- 1o0sely on the pipe;as indicated by the' spa.ce shoWn in Figure 3, so that it will under no c0ndition's bind o-r beconn tight on the pipe.

'Ihe lower end cf the': element 30 is curved forwardly in the direction of travel of t he machine a.nd twisted about With respect 1:0 a vertical axis to provide an efiicient furrow-forming means.. As indicated i'n Figum 1, the lower end of the eleme'nt 30 provides a sharp shallo'w funrow'which gives a, distinct mark for following by the planter on the return trip across the field.

Figure 3 in dotted lines shows the element 30 piv0ted about the shaft I4. It will be noted thad: this movement raises. the lower extremity cf the element and alsolessens the angle 0f the cout'acting surface with respect Iio the ground, if the element is moved -in a rea.rward direction. II: Will be understood, therefore, that when the It is to be understood that applicant has shown and described on1y a preferred embodiment of his improved loosely mounted marl;ing element, and that all modifications falling within the' scope of the appended claims are contemplated as a part of the invention.

What is claimed is:

1. In combination with a planter marker st1'ucture mounted for float ing movement, an extension carried by the marker structure, a downwardly extending marker element pivoted on said structure, said element being curved at its lower end forwardly in the direction of operafiion of the planber to provide a furrow opener, anc1 means with an abutment 130 limit thmg rearward movement of said element and to permit forward movement to reduce the ground-engaging pressure of the marker e1ement when the marker structure ls moved in a rearwarddirection.

2. In combination with a "planter' marker struture mounted for floating movement, an extension, a downwardly extending marker element pivoted on said structure, and mearis provided with an abutment to hold said e1ement against endwise movement, 110 limit the rearward movement of said element, and to permit forward movement 130 reduce ground-engaging pr essure of the marker element when the marker structure is moved in a rearward direction.
