LAN D-MARKER.

SPECIFICA'IIION forming part of Let-ters Patent No. 543,877, dated August 6, 1.895.

Ipplication filed May 13, 1895. Serial No. 549,144. (No model.)

T LLZZ whom, iv' may concern:

Be itknown that I, WILLIAM M. LEwIs, a citizen of the United States, residing at Walnut, in the county of Marshall and State of Indiana, have invented certain new and usefulV Improvements in Land-Markers for Corn Planters; and I do hereby declare the following to bea f ull, clear, and exact description of the invention, such as will enable others ro skilled in the art to which it appertains to make and use the same.

My invention has reference to improvements in land-markers for corn-planters, and seeks to so improve the construction of the I5 marker as to enable it to yield to and pass over obstructions and also to simplify the construction of the parts which support and reverse the marker. These objects Ivattain by the useof the device illustrated in the accomzo panying drawings; and the invention consists in certain novel features of the same, as will be hereinafter described and claimed.

In the drawings referred to above, Figure l is a plan view of my improved marker and so much of the corn-planter frame as is necessary to a proper understanding of the invention, and Fig. 2 is a rear elevation of the'sarne.

The planter-frame A consists ot longitudinal and transverse beams or sills B and forms 3o no part of my present invention. In the rear transverse beams of the frame I journal a rock-shaftA C, the rear extremity of which is forked, as at D, and has pivoted thereto the end of the marker E. The marker is con- 3 5 structedin two sections F G, which are joined by the coupling-plates H, vsaid plates being rigidly secured to the upper land lower sides of the inner member ofthe marker andvhaving the outer member or section pivoted be- 4o tween their outer ends. The inner end of the outer section extends inward beyond the pivot I, and a frangible pin orv key J is inserted through said inner end and the connecting-` plates. Journaled in suitable bearings upon the frame and near the sides thereof are the longitudinally-disposed rock-shafts K, havingr their front ends provided with the foot-levers L, projecting inward toward the medial line of the frame, and their outer ends provided with the outwardly-projecting marker-supporting arms M, as clearly shown. The extremities of these marker-supporting arms are formed into or provided with the lateral rests N, which receive the marker and are provided with the vertical prongs or stops to guide the marker into proper position and prevent too great play of the same. The markersupport ing arms are held up in their proper positions by springs O, which are secured to the rear end of the frame and project` laterally outward and bear against the under sides of the said arms at the ends of the same.

The machine' is drawn over` the ground in the usual manner, and the marker operates as usual. When the end of the line has been reached, the foot-lever is depressed, so as to raise the marker sufficiently to permit the machine to be turned. Thedriver then may dismount and reverse the marker, or he may reverse it by giving the foot-lever a sharp downward thrust, thereby throwing the markerv over to the opposite side of the machine.

'Should the marker strike a stone or other unyielding obstruction, it will swing slightly backward until arrested by the rear prong, and the continued travel of the planter will then cause the frangible pin to break, so that the outer member or section willswing around the obstruction. A new pin may be quickly inserted and the planter then driven on over the field. y

It will be seen that I have provided a very simple marker, which can be quickly and easily reversed and which will readily pass over obstructions.

Having-thus described my invention, what I claim, and desire to secure by Letters Pat ent, is'

The combination with acorn planter frame, of a land marker attachment, consisting essentially of a marker arm E pivoted to the rear of the frame and adapted to swing vertically from one side to the other, a pair of rock shafts K extending longitudinally of the frame, one of said shafts being journaled on each side of the pivot of said marker arm-and each rock shaft being provided at its forward end with an inwardly turned foot lever and at its outer end with an outwardly turned In testimony whereof I ax my signature marker-supporting arm provided with a lat in presence of two witnesses. eral rest for1 the marker arm, and springs secured tothe frame and bearing on the un u WILLIAM M. LEWIS. del` side of the marker-supporting arm and Witnesses: adapted to resiliently support the same, sub- J. L. MCCOY,

stantially as described. E. M. MCCOY.
