Patented Apr. 21, 1931 PATENT FFlQE IRA MOORE, on PEORIA, ARIZONA LAND MARKER Application filed June 24,

v The present invention relates to land markers for agricultural machines, and contemplates a device in the nature of an attachment that can be conveniently attached to any type of machine.

One of the chief objects of the present invention resides in the provision of a construction, wherein the marker can be quickly and easily arranged in a position for use, or moved to an elevated position when'not in use, and maintained in the latter position by its own Weight, a lever being employed to shift the marker to either of its two positions and located within convenient reach of the operator. 7 v V More specifically stated, the invention embodies among other features, a bar adapted to be rigidly mounted transversely of the machine, the bar supporting the markers at both ends, which are independently controlled so that either or both can be arranged in a position for use as the occasion may require.

The nature and advantages of the inventionwill be better understood from the following detailed description when read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed. 7

In the drawings'forming part of this application like numerals of reference indicate similar parts in the several views and where- 1n:

Figure 1 is a top plan view of a machine showing the invention applied thereto, with one marker lowered into a position for use, and the other marker at the opposite side of the machine elevated. v

Figure 2 is a side elevation of the machine illustrated in Figure 1.

Figure 3 is a rear elevation thereof.

Figure 4: is a sectional view on line 4-4: of Figure 3.

Figure 5 is a fragmentary sectional View through one of the markers.

While I have illustrated my invention in conjunction with a planter, it is of course to be understood that it can be attached to other types of agricultural machines if so desired,

the machine with which it is used. As clearly illustrated in Figures 1 and 3, the bar 10 projects an appreciable distance beyond the wheels of the machine, and is utilized to support markers, that can be quickly and conveniently lowered into position for use, or moved to an elevated position when not in use.

As clearly illustrated, there are two mark,- ers mounted on the bar 10, one at each side of the machine, and these markers are capable of being used singly or conjointly as the occasion may require. Each marker 12 is carried by the section 13 of a longitudinally adjustable shaft, the other section 14- being hollow and telescopically receiving the section 13 as illustrated in Figure 5. Consequently, the shaftcan be varied in length to permit the marker- 12 to mark the ground at any desired distance from the adjacent wheel of the machine. The sections 13 and 14 of each shaft are held fixed relatively in a given position by a set screw 15. Connecting each shaft at a point adjacent its outer end to the forward portion of the frame of the machine is a rod 16, onelend of which is passed through an apertured lug 17 carried by the shaft, while its opposite end is passed through an opening formed in a bracket arm 18 secured to the adjacent machine.

For raising and lowering each marker I employ a lever Y19, and these levers are pivoted upon the bar 10 adjacent the operators seat 20, so that either or both markers can be controlled, or shifted from one position to the other by the operator while occupying the seat 20.

The means connecting each lever with its particular marker includes a link 21 which is pivoted as at 22 upon the bar 10, and the outer or free end of this link is connected with the lever 19 through the instrumentality of a link 23. Also connecting the link 21 portion of the frame of the with the shaft of the marker is a link 24, when the lever 19 is shifted laterally in one direction to lower the marker into engagement with the ground for use, the various links assume the position illustrated at the right of Figure 3. However, when using the marker is not desired, the lever 19 can be moved in the direction of the seat 20, whereupon the shaft of the marker is moved to an elevated position as indicated at the left of Figure 3. lVhen the shaft of the marker assumes this position, the link 21 is arranged behind parallel with the bar 10, in which position it engages a stop element 25, preferably in the nature of a hook carried by the bar 10 and shown in Figure lVh-en the link 21 assumes its folded position parallel with the bar 10, it is received by the hooklike element which of course limits the movement of the link in one direction, wh the shaft of the marker assumes an elcvai a position, and slightly at an inclination *0 ward the seat 20, so that the shaft marker is maintained in this po own weight, and thereby elimin sity of clamps and other an for holding the shaft and i n J c; in an out-of-the-way position. The aiiangement of the links relatively, and the manner in which they connect the lever 19 with the shaft 14 is such that the marker and its shaft can be quickly lowered into contact with the ground for use, or elevated to an out-of-theway position with very little effort on the part of the operator.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily understood, I desire to have it known that I do not limit myself to what is herein illustrated and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim is:

1. An agricultural machine attachment comprising a bar adapted to be mounted transversely of the machine, a marker including a. shaft pivoted on said bar, a lever pivoted on said bar, links pivot-ally connecting the lever with the shaft, one of said links being pivotally connected with the bar, whereby the shaft can be elevated or lowered. with relation to the bar, said shaft being maintained in its elevated position by its own weight.

2. An agricultural machine attachment comprising a bar adapted to be mounted transversely of the machine, a marker including a shaft pivoted on said bar, means for elevating and lowering said shaft with relation to the bar, and including a lever pivoted on said bar, a link pivoted thereon, links pivotally connecting the lever and said shaft with the aforementioned link, and means for supporting the first-mentioned link parallel with said bar when the shaft is elevated.

3. An agricultural machine attachment comprising a bar adapted to be mounted transversely of the machine, a marker including a shaft pivoted on said bar, a lever pivoted on said bar, a link pivoted thereon, links pivotally connecting the lever and shaft with the aforementioned link, whereby said shaft can be elevated or lowered. with relation to said bar, a hook-like element carried by the bar and adapted to receive and limit the movement of the first-mentioned link in one direction, whereby said shaft is maintained in an elevated position by its own weight.

4. An agricultural machine attachment comprising a bar adapted to be mounted transversely of the machine, markers carried by both ends of the bar, each marker including a shaft composed of telescopic sections, means for holding said sections fixed relatively, a lever pivoted on the bar for each marker. and links pivotally connecting each lever with. the shaft its respective marker, one link being pivotally mounted on said bar, whereby the marlazers at either end of the bar can be lowered into contact with the ground aft each marker is supported in its yed position by its own weight. lntestimony whereof I affix my signature.

IRA MOORE.
