CHECK-ROW CORN=PLANTER.

SPECIFICATION forming part of Letters Patent No. 390,529, dated October 2, 1888.

A pplioation filed March 16, 1888. Serial No. 267,864. (No model.)

To all whom it may concern.-

Be it known that I, NILs O. STARKS, a citizen of the United States, and a resident of Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Check-Row Corn-Planters; and I do hereby declare that the following is a full, clear, and exact description of the invention,which willenablc others skilled in the art to which it appertains to make-and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of my improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a similar view at right angles to Fig. 2. Fig. 4 is a vertical sectional view on the line mm, Fig. 2. Fig. 5 is a similar View on the line y 3/, Fig. 4; and Fig. 6 is a view of the sector as it appears when viewed from the inner and under side.

Like letters of reference denote corresponding parts in the several figures.

My invention has relation to mechanism for operating the seed-slide in a check-row cornplanter of that class in which said slide is operated by mechanism actuated by means of a cord or chain provided with knots or buttons in the well-understood manner. My'improvement, however, has no relation to that part of the mechanism which receives and again pays out the knotted cord or chain at the side of the machine, but has relation solely to the peculiar construction and combination of parts of the device, whereby a reciprocating motion is imparted to the seed-slide, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying two sheets of drawings, the letters A A denote the usual mechanism which receives the knotted cord or chain at the front end and pays it out at the opposite end, the said cord or chain passing over the front pulley, B, then between the arms of the forked lever D, and then again out between the rear pulleys, C and E, where it leaves the machine. The bifurcated lever D has its fulcrum at F, and is provided with a bracket or projection, G, having a stud, H, upon which a red, I, is pivoted. The rear end of this lever D is connected by a spring, (I, to

the rearward end of the plate or bracket which supports the pulleys B and C.

Inasmuch as the several parts of this mechanism form no part of my improvement, a further description of the same is not deemed necessary in this connection, as its construction and operation will be fully understood by all persons conversant with the art to which it appertains.

Upon the middle of the machine, midway the parts A A, is a vertical sleeve, L, the lower part of which forms a cross'head, l, and trunnions m m, which are secured in suitable bearings or standards, J J.

Rocking sectors M M arcjournaled upon the trunnions, between their bearings and the cross-head of the sleeve, which crosshead forms abutments for the sleeves of the sectors, as seen more clearly in Fig. 4. of the drawings. The said vertical sleeve is supported by brack cts N N, bolted to any suitable part of the frame of the machine in such a manner that they will not be in the way of the rocking sectors during the operation of the machine. Through this central vertical sleeve or collar L is inserted a shaft, 0, the lower part of which is provided with a crank, P, having an adjustable wrist-pin, p, which is connected to the seed-slide (indicated in dotted lines) in the usual manner. The upper end of shaft 0, which projects above the sleeve, is provided with a pinion, 0, engaging a coggcd segment, Q, 011 the inner face of each of the rocking sectors M M. Each of these sectors above the aforesaid cogged segment is provided at each end with a beveled shoulder or offset, R, and also with a flange, S, which said flange is bent inwardly, so as to form a cam, T, the point of which lies midway between the shoulders RB and is flush with the inner side of the sector. Each sector is provided with an arm, U, and asleeve, U, whereby it is connected to its ap propriate trunnion m. When the rocking sectors are placed in juxtaposition to each other, their inner flat faces will slide upon each other, and their upper rounded hearing, which is provided with the shoulders or offsets R, will, by the cam-flanges S, form a groove or way adapted to receive the bent ends or shoes 2 1', whereby the rods I I are connected to the bifurcated levers at the sides of the machine.

These bent ends or shoes 1' of the connectingrods I are bent inwardly and pointed or rounded, so as to engage recesses r in the offsets or shoulders It, and said rods I, where they engage with the sectors, are prevented from becoming disengaged or slipping out of the groove in which they play by means of the bails or keepers V V, which are suitably fastened to laterally-projecting ears of the central sleeve, L, which said ears may also form means of attachment for the supportingbrackets N N.

At one end each of the rocking sectors is preferably provided with a downwardly-projecting guide-piece, W, overlapping the under side of the opposite sector and adapted to form a stop when it comes in contact with the ends of the cogged segment Q opposite.

The operation of my device is as follows: When the machine is at rest, or in the position shown in Fig. 1, the inner ends of the connecting-rods I I will rest with their shoest' iin the groove formed by the flanges S S between a pair of shoulders on opposite sectors. When U the knot or button strikes the forked lever and tilts it back, the connecting-rod on that side of the machine will be pulled back against the shoulder or offset with which it engages, thus drawing the appropriate sector, of which this offset forms a part, with it, and tilting the sector to one side. This, of course, also tilts the appropriate cogged segment Q, and as this meshes with the pinion 0a one-half revolution is imparted to the vertical shaft 0 and the crank at the lower end of the same, and whereby, again, the seedslide is operated by pushing it to one side. After the cord or button, however, has become disengaged from its appropriate lever, the tension of the spring d will draw it back into its normal position, whereby its connecting-rod I is pushed back, so as to release the shoe On the backward stroke of the rod on the way to assume its normal position the cam T, formed by the flanges S S, will guide the free end of the rod over upon the opposite sector, so as to bring it into engagement with its appropriate shoe 6 of the same, and thus at each reciprocation of the forked or bifurcated lever its appropriate connecting-rod will alternately engage opposite sectors, and thereby rock said sectors alternately forward and back, thus rotating the pinion with which these sectors engage alternately in opposite directions. This movement not only operates to reciprocate the seed-slide, but as the pinion engages with both the sec tors the sector which has just been released from the connectingrod is brought back into its normal position by the pinion, ready toreceive the connecting-rod at the next stroke of the machine. As both connecting-rods operate precisely alike, it will be seen that the sectors will be actuated in precisely the same manner, whether one side of the machine is in use at rest while the other is in operation.

As the rocking sectors, with their several parts, may all be cast in a single piece, it will be seen that this device consists of but few separate parts, which are inexpensive in their construction, readily put together, and certain in operation, so that this improvement may be manufactured at comparatively a small cost, and will prove not only absolutely certain and effectual in use, but very strong and durable, so that it is not apt to break or otherwise get out of order, even if the machine is subjected to exceptionally rough usage.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a check-row corn planter, the combination of rocking sectors with the connecting-rods and bifurcated levers, whereby a reciprocating motion is imparted to said rods, substantially as and for the purpose shown and set forth.

2. The combination of the rocking sectors each provided with an arm and a sleeve, and also with a cogged segment on its inner side, the pinion engaging said segments, the pinion-shaft, and the crank at the lower end of the same for actuating the seed-slide, substantially as and for the purpose shown and set forth.

3. The combination of the rocking sectors, the connecting-rods, a central sleeve having ears upon its sides, and the bails or keepers secured to said ears and straddling the sectors and connecting-rods, substantially as and for the purpose shown and set forth.

4:- The combination, with the rocking seetors having the studs or offsets at their ends, and having the side flanges bent to form the cam T midway between the shoulders, of the rods I I, the ends of which are bent inwardly and pointed, substantially as and for the purpose shown and set forth.

5. The combination of the rocking sectors having cogged segments Q, and each having a downwardly-projecting guide-piece at one end, with a pinion meshing with said segments, substantially as and for the purpose shown and set forth.

6. The combination of the central vertical collar having a cross-head at its lower end, the journals or pintles at opposite sides of said cross-head, the rocking sectors provided with trunnions working upon said journals and having cogged segments on their inner sides, the crank-shaft journaled in the central sleeve, and the pinion at the upper end of said shaft, adapted to mesh with the cogged segment, substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

NILS O. STARKS.
