ROLLA EDYVARD MUDD, OF STRONGHURST, ILLINOIS.

MARKER. FOR COBN-P LANTERS.

Specification of Letters Patent.

Patented Apr.6,1915.

Application filed September 17, 1913. Serial No. 790,193.

To all whom it may concern Be it known that I, ROLLA E. MUDD, a.

citizen of the United States, and a resident of Stronghurst, in the county of Henderson and State of Illinois, have invented a new and Improved Marker for Corn-Planters, of which the following is a full, clear, and exact description.

The objects of the invention are to provide a simple, strong, and inexpenslve marker for corn planters; which can be easily and quickly attached to any make of corn planter; which is operable from the drivers seat; and which will mark on any kind of ground, rough or smooth, hilly or level.

I obtain the above objects by providing a support adapted to be secured to a frame on a corn planter; a marker arm pivotally secured to said support; and means carried by the support and whereby saidarm can be thrown from one side to the other for marking, and, also, can be placed in inoperative position.

The invention consists of the construction and combination of parts to be more fully described hereinafter and fully set forth in the claims. Reference is to be had to the accompanying drawings forming a part of this specification, in which like characters indicate corresponding parts in all the views and in which:

Figure 1 is a rear elevation of a corn planter provided with an embodiment of my invention; Fig. 2 is a plan view of the same; Fig. 3 is an enlarged rear View of the operating lever; Fig. i is a section on l1ne 4.4c of Fig. 1; and Fig. 5 is a line on section 5-5 of Fig. 3.

Referring to the drawings, 6 represents a frame of a corn planter of any construction to the rear portion of which is secured a support 7 formed of two members 8 and 9 connected at the ends and spaced therebetween from each other. The support 7 is secured to the frame 6 in any suitable way, the member 9 being adjacent to the frame and one end of the support extending to one side of the frame. The secured portion of the support 7 is provided with a laterally extending pin 10 lying substantially in the longitudinal axis of the frame; and mounted thereon by a screw 10 is a member 11 adapted to swing in a substantially vertical plane with the said pin 10.

The member 1 11 is. provided with lateral lugs 12 between which is pivotally mounted a marker arm 13. The member ll'is also provided with a spring 14 normally tending to deflect the marker arm from the frame, thereby maintaining taut the flexible element 15 which connects the end of the arm 13 carrying the pointer 16 and the member 17 positioned on the frontv end of the frame. The overhanging end of the support 7 receives a member 18 positioned between the members 8 and 9 and secured thereto. Pivotally secured tothe support, that is, to the members 8 and 9, at the overhanging end,

is a lever 19. The pivoted end of this lever is preferably bifurcated; and at'fthe base of the bifurcation it is provided with a central extension 20 to which is centrally pivoted a link 21. One end of this link is secured to the member 18 by means of a coil spring 22, while the other end of said link is connected by means of a rodo'r link 23 to the same member 18. The link 23 has its connection with the member 18 in a point lying between the pivotal connection of the lever 19 and the spring 22, but closer to the pivoted connection of the lever 19 so that when the lever is in a substantially vertical position the said lever is past dead center.. The lever 19 is also provided with a pivotally mounted clamping member 2d through which passes a rod 25, one end of which is pivotally connected to the arm 13, the other passing through the clamping member. This rod 25 connects the marker arm 13 and the operating lever 19. By means of the clamping member 24:, the dis tance between the arm 13 and the lever19 can be varied. The support 7 is so secured to the frame 6 that the lever 19 is disposed adjacent the seat 26 provided on the frame 6 and from where this leveris operated by.

theldriver. By moving the lever 19 from the position shown in full line in Fig. 1 to the position shown in dot and dash in the same figure, the marker arm 13 is made to swing in a substantially vertical plane about the pin 10 to an upright position shown in dot and dash in Fig. 1. The marker arm remains in an upright position, as stated, due to the fact that gravity tends to make it fall toward the right and this is counteracted by the spring 22, which prevents any movement of the lever 19 back to the left. To push the mounted arm 13 to the position shown in lower dotted line, Fig. 1, that is,

into the right hand operative position the said arm is slightly forced by the driver from the seat downward, simultaneously pulling on the lever 19 to bring it to the position shown in full line, thus causing the arm 13 to take the position shown in lower dotted lines in said Fig. 1.

As can be easily seen from the drawings, any unevenness in the ground with. which the pointer 16 is in contact will cause the arm 13 to move on its pivot without in any way interfering with the lever 19, which. lever will follow the movement of the arm 13 produced by the unevenness of the ground. If it is desired to increase the ten sion on the pointer 16, the rod 25 can be so adjusted by means of the clamp 24 so that the same will only slightly touch the ground, by being counterbalanced by the coil spring 2%. The flexible member 15, when the arm 13 is thrown from one side to the other, is caused to move on the member 17 from one end to the other. The spring ii is intended to maintain this flexible member 15 in a taut condition.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. In a marker for corn planters, a sup-- port; a marker arm pivotally mounted on said support; means for swinging said support from one side to the other operable from the drivers seat and comprising a. pivotally mounted lever, a pivotally mounted link on said lever, a second link connecting one end of said link to the support, a coil spring connecting the other end of the link to the support, a rod connecting said lever to the arm, the connection of the lever with the arm being eccentric of the pivot of said arm and adjacent the pivot, whereby to move the marker arm from one side to the other side of the planter, said lever must be moved from and back to its original position.

2. In a marker for corn planters v-a support; a member pivotally mounted in said support adapted to swing in a substantially vertical plane; a marker arm pivotally Copies of this patent may be obtained for 1,13a,se1

mounted. in said member; a spring tending to move said arm on its pivot and thereby separate the arm from the member; a lever pivotally mounted on the support; a centrally pivoted link on said lever; a second link connecting one end of the firstmentioned link to the support; a coil spring con necting the other end of the link to the support; a connecting rod from the arm to the lever; and a clamp on said lever engaging said rod and whereby the distance between the lever and the arm can be varied, substantially as and for the purpose set forth.

3. In a marker for corn planters, a support; a marker arm pivotally mounted on said support; an operating lever connected to said support; an adjustable rod connection from said arm to said lever; the connection of the arm with the rod being eaten trio to the pivot of the arm; a resilient member tending to move the lever in a predetermined direction, and a link from the support to the lever limiting the movement of the lever in said predetermined direction whereby the marker arm is adapted to be maintained in inoperative position.

4. In a marker for corn planters,a support; a marker arm pivotally mounted on said support; an operative lever associated with said support; a rod connecting the arm to the lever, the connection of the arm with the rod being eccentric to the pivot of the arm; a link pivotally mounted on said lever; a second link connecting said link to the su; port; a resilient member also connecting the link to the support, said second link limiting the movement of said lever in a predetermined direction, and said resilient member being adapted to maintain the marker arm in inoperative position when said lever is moved to its limit position in said predetermined direction.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROLLA EDWARD MUDD.
