conn-PLANTER.

SPECIFICATION forming part of Letters Patent No. 638,799, dated December 12, 1899.

Application filed June 3,1899. Serial No. 719,287. (No model.)

To all whomt' may concern:

Be it known that I, HUGH SUMNER CRAW- FORD, a citizen of the United States, residingv at Sumner, in the county of Ohariton and State of Missouri, have invented a new and useful Corn-Planter, of which the following is a speciiication.

My invention relates to the general class of corn-planters, but more particularly to checkrow planters, and has for its object to provide a planter of the kind described adapted to check off the rows without the necessity of employing a line of wire, anchors, and like appliances such as are now in use with this class of machines.

Afurther object is to so construct a machine that the mechanism will be operated as the machine moves forward through the medium of the axle on which the traction-wheels are secured.

A still further object is to provide means for throwing the mechanism in and out of operative engagement with the axle.

With these objects in view my invention consists of a transverse rock-shaft journaled on the forward portion of the machine and carrying valves er cut-offs at either end,whereby the feed of the hopper to the spouts can be regulated.

My invention further consists in a marker to be used in conjunction with the feed mechanism, whereby the position of the planted grain will be marked immediately7 after it has been dropped.

My invention further consistsin providing means for operating the feed mechanism and marker alternately.

With these objects in view my invention consists in the parts and combination of parts, as will be more fully described, illustrated, and claimed.

In the drawings, Figure 1 is a perspective view of a planter, showing my invention applied. Fig. 2 is a side elevation showing the attachment in its normal position. Fig. 3 is a similar view showing the attachment in its Y extended position.

Fig. 4 is a transverse section on the line 4 fi, Fig. 2. Fig. 5 is a detail Referring to the drawings by numerals, 1 represents the main frame of a planter, to the forward end of which is secured the usual runner-frame 2, carrying any well-known construction of runners, such as 3, provided with suitable spouts or Shanks 4, with which the openingsin the bottoms of the hoppers 5 communicate.

Journaled tothe frame l in the bearings 6 is a transverse shaft or axle '7, carrying the traction-wheels S on its respective ends, and a rigidly-secured sleeve 9 adjacent to the hub on the axle. lt is obvious that should it be found convenient or desirable this sleeve could be secured directly to the hub of lthe wheel instead of applied to the axle.

10 are a series of seri-ations or teeth on the inner face of the slee ve 9, which are adapted to register with a similar ratcheted face on the outer face of the star ork cam Wheel 11. This cam-wheel 11 is loosely sleeved on the shaft 7 and is provided with a rearwardlyextending sleeve 12, which carries a circumferential flange 13. Pivotally secured above Ithe aXle and to a suitable support 14:A is a bifurcated clutch-lever 15, the bifurcated end of which is adapted to engage the rearwardlyextending sleeved portion of the cam-wheel or release the same from or in operative engagement with the axle 7, as will be more fully referred to hereinafter'.

Secured to the side of the frame 1 is a bracket 16, projecting out to about the horizontal longitudinal center of the cam-wheel and thence upwardly at an approximate right angle and bifurcated, as shown at 17, and provided with a series of perforations 18, adapted to receive a bolt or pin 19, to be hereinafter referred to.

At the juncture of the right-angle extension with the bracket 16 is a longitudinallyextending sleeve projecting on either side thereof and in which is journaled a reciproeating rod 20, carrying on its rear end a shoe 2l and pivotally connected at the other end to a bifurcated conneetinglink 23 is a transversely-extending rock-shaft secured on the runner-frame and carrying the cut-offs 23, (of any well-known construcof the shanks or spouts.

ICO

2i is an upwardly-extending lug or projection rigidly fastened to the rock-shaft 23 and pivotally connected-to the connecting-link 22 at 25.

Journaled in the upper part of bifurcated arm 17 of the bracket IG and intermediate its ends, as at 16a, is a curved lever or rod 26, connected to the reciprocating rod 2O and provided with a slot 28 in its upper end.

29 is the marker-rod, slidably secured in the bracket 30 and passing down between the inner sides of the link to the ground immediately in rear of the spouts and carrying a spring-cushioned shoe 3l, which will be of sufficient shape to mark the ground where the grain has been dropped.

A spring 32 is attached at its forward end to the link 22 and at its rear end to a T-shaped bolt resting in the bifurcated portion of the bracket 16.

The operation of my device will be as follows, all parts being assembled: The forward movement of the planter will rotate the axle, and by throwing the clutch mechanism in operative engagement the cam-Wheel will rotate and the radial arms will strike against the shoe on the end of the reciprocating rod,whicl1 will force it forward and operate the cut-offs on the ends of the rock-shaft and at the same marking the place where the grain has been planted immediately after the same has taken place. As the reciprocating rod is forced forward the coil-spring expands, and as soon as the force is removed the tendency of the spring to contract will cause the rod 20 to slide rearwardly to its fullest extent, which action will cut oif the grain from the spouts and by raising the forward end of the curved lever 26 raise the marker-shoe ofI" the ground.

The tension of the spring can be regulated by removing the pin in the openings of the bifurcated portion of the arm 17 and sliding the T-headed hook either up or down and then inserting the pin.

From the foregoing it will be seen that I have invented an improvement in check-row planters which while simple will be durable, easy to manufacture, and one which will be readily appreciated by farmers generally.-

Vhile I have illustrated what to me appears to be the best means to accomplish the results desired, I would have it understood that I reserve the right to make such changes and modifications as would properly come within the scope of my invention without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a check-row planter the combination with a main frame of a revoluble axle carried thereby, a reciprocating rod mounted on said frame and connected to a cut-off in the spout in the supplemental frame, a marker secured to the main frame in rear of the cutoff, a connection between the rod and the marker and means carried by said axle for actuating the rod and cut-off, substantially as described.
