AUTOMATIC llClAt'tKEIt.l

To all whom @'15 may conce/m Be it known that T, CLARENCE C. COX, a citizen of the United States, residing at Vigo, in the county of Ross and State of Chio, have invented new and useful Improvements in Automatic Markers, of which the following is a specification.

This invention relates to planters and more particularly to marker attachments for this type of agricultural impleinent.

@ne of the principal objects of the invention is to provide a marker which may be readily mounted upon the ordinary type of corn planter and be conveniently operated so that the marker disk or member may be easily raised when turning at the end of the row and which also may be operated from either side of the machine.

A further object of the invention is the ff provision of a device of this character which embodies a safetv appliance adapted to prevent the marker rod from breaking when the marker member strikes an immovable object.

il still further object of the invention will appear as the following specific description is read in connection with the acconipanying drawings which form a part of this invention in which Figure 1 is a top plan view showing the device attached on an ordinary corn planter. l? ig. 2 is a rear elevation. Fig. 3 a detail side elevation of the machine showing the alternative position of the lever in dotted lines. Fig. et is a detail section through the marker rod.

Referring more particularly to the drawings, 1 represents an ordinary corn plantel' frame which is supported upon the wheel axle 2, the latter member carrying the usual covering and supporting wheels 3 secured to the rear member e: of the frame and to an intermediate cross brace 5 are suitable bearings G in which a shaft 7 is journaled. This shaft has its rear end turned at right angles as shown at S and its terminal. end bifurcated as shown at 9 to receive the pivoting end 10 of a stub shaft 11. The stub shaft 11 is entered into the marker rod 12 which is in the form of a pipe of any suitable cross sectional contour and carries upon its outer end a suitable marking disk 13. The shaft 7 is also journaled adjacent its right angular end in a bearing 111-. which is carried by a frame 15 secured to the main frame 1 and ySpeccation of Letters Patent.

Application filed August 12, 1911.

Patented July 22, 1913. Serial No. 643,722.

having lvertical offset ends so that it will be depressed below the main frame, These bearings are all reu'iovably mounted upon the planter and the frame 15 similarly mounted so that the attachment may be readily removed or placed upon the frame when desired. Surrounding the shaft 7 is a clamp 1G and a similar clamp 17 surrouucs the tubular rod l2 and is connected to the first clamp by a link or brace rod 1S. This brace rod connected to the clamp by a frangible pin 18a, for a purpose which will be hereinafter described.

Journaled upon the shaft 7 `is a bearing member 19 which is held againstlongitudinal movement upon the shaft by transverse pins 2O extending through said shaft. The bearing 19 is provided with a laterally extending nipple in which one end of an operating shaft 21 journaled, the opposite end of the shaft being journaled in a bearing 2Q removably mounted upon the side of the main frame 1 between the legs of a locking segment 23 also secured to the frame. The end of the shaft 21 has secured thereto a lever 241 which carries the usual spring locking dog 25 operated by the handle and link connection 26 and adapted to engage a notch in the center of the segment 23. The shaft Q1 carries a beveled gear Q7 which meshes with a similar gear Q8 keyed to the shaft 7 so that by raising the lever to a position where the .locking dog engages the notch in the segment, the shaft i' will. be given a quarter of a revolution and the marker 13' will. ble raised to a ver-ticalposition. By continuing the movement of the lever in the same direction or to the position shown in dotted lines in Fig. 3, the marker may be positioned upon the opposite side of the machine. The pin 18 has sullicient strength under ordinary circumstances to hold the marker rod in alinement with the extension S. Tf,however, the marker should engage an immovable obj ect, such as a stump or large rock, the pin 18il will break and the marker rod will pivot on the extension S, thus preventing the marker rod from breaking.

Having thus fully described the invention, what I claim is v ln combination, a planter frame, a shaft journaled therein, a pivoted lever, a gear connection between the lever and the shaft whereby the shaft may be positively rotated in either direction, a right angular end upon In testinion)7 whereof I aiix iny signature the shaft, i stub shaft pivoted upon said in presence of two Witnesses.
