CHECK-ROW CORN-PLANTE R.

SPECIFICATION forming part of Letters Patent No. 437,633, dated September 30, 1890. Application filed May 6, 1890. Serial No.- 350,7'70. (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 will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in check-row corn-planters, and more particularly in certain improvements upon the checkrower attachment used in connection with the corn-planter described in Letters Patent of the United States issued to me under date of May 28, 1889, and numbered 404,318.

Heretofore in check-row corn-planters it has been found difficult to provide a construction whereby the knotted wire is thrown out of engagement with the slotted lever or fork for the purpose of avoiding the necessity of the driver alighting from the machine at the end of the row until after the said machine is turned.

' No. 404,318, showing my attachment applied thereto. Fig. 2 is a plan View of the checkrower detached from the machine, showing in full lines the forward sheave or roller occupying its normal position, and in dotted lines the same part occupying a perpendicular position. Fig. 3 is a cross-sectional View on the line a; 00, Fig. 2. Fig. 4 is a detail View; and Fig. 5 is a cross-section on the line y y, Fig. 2. Fig. 6 is a detail View of the device for dotting the knotted cord, showing the same open.

Like letters of reference refer to like parts throughout the several views.

In the accompanying drawings, the letter A indicates the frame or body of a corn-planter embodying my improvement, and B the seed receptacle or hopper thereof. The cross-beam G of this frame has projecting rearwardly therefrom a bracket D, which, together with a similar bracket upon the opposite side, (not shown in the drawings) afford bearings for a transverse shaft E. This transverse shaft is also provided with end bearings F, which form means of connection with the checkrower, as will hereinafter more fully appear.

The letter Gr indicates the frame of the check-rower attachment, said frame consisting of three pieces or arms G, G and G formed and connected in the manner clearly indicated in the detail view of the drawings. The arm G is provided with a series of boltholes, forming means for attachment to the seed-hopper, while its rear end is bent into angular form, as indicated at g. The arm G2 at its upper rear end has extending therefrom a lateral bolt H, upon which is mounted a roller or sheave I. This arm G from its upper rear end is inclined downwardly to the point 9 and from thence it is inclined upwardly, the extreme upper end of this latter portion being bent intoangular form, as indicated at 9 The arm G3 has journaled between its upper rear end and the rear portion of the piece G2 a roller or sheave J, said roller being mounted upon a transverse shaft K. This arm G is then continued downwardly to the point g, from where it extends upwardly, the extreme upper end terminating in a bend at right angles, designated by the letter g and corresponding to the bend in the arm G Between these two corresponding ends of the arms is passed a shaft or bolt L, upon which is loosely mounted a bifurcated bracket M, said bracket carrying a roller N. The lower arm of the bifurcated portion is also provided with a downwardly-projecting lug m.

Slightly to the .rear of the bracket just referred to is a transverse shaft 0, passing through and between the arms G2 and G and connecting the end of arm G therewith. Upon this shaft is loosely mounted an arm or pawl P, provided upon its upper end with a perforation p, and at its lower side with a forwardly-projecting lug p, which is adapted to bear against the downwardly-projecting lug m of the bracket and force the latter from its normal horizontal position to a'perpendicular position. This is effected through the medium of a cord Q or equivalent secured at one end to the perforation p of the arm and extending rearwardly to the main frame of the device.

It will also be seen that the pawl P is provided at its upper end with a shoulder or lug 11 which is adapted to engage the raised rim m of the bracket, and thus lock said bracket in its horizontal position.

Slightly to the rear of shaft is still another shaft R, which isfree to turn in its bearings in the two arms, and has mountedthereon a sleeve S, which has extending upwardly therefrom a bifurcated or forked lever T, while its inner end is formed into a crank U, said crank having mounted thereon a serrated arm V, provided upon its rear end with a perforation '0.

The letter W indicates an arm, which is formed at its rear end into a link to, adapted to be secured to the end bearing I of the rock-shaft, while its forward end is formed into an elongated slot w, having the face thereof, which is contiguous to the serrated arm V, also provided with serrations, which mesh with those of the adjacent arm. The

' two arms are secured togetherby means of a arm W.

bolt X, which passes through the perforation of arm V and through the elongated slot of It will thus be seen that the leverage of the latter arm may be readily adjusted simplybyloosening the nut which retains the bolt rigid and moving arm WV either forward or rearward, as needs be.

The usual knotted wire or rope which is stretched across the field to be planted first engages the forward roller or sheave N, then passes between the forked ends of the lever T, and then finally passes between the rear rollers I and J. When the knot upon the wire or rope engages the forked lever, it will drawit rearward, aswill be readily understood.

The motion thus imparted to the forked lever by the knotted wire or rope will be transmitted to the rock-shaft through the medium of the mechanism already described, and when my check-rowing device is used in connection with a corn-planter similar to that described by me in Letters Patent No. 404,318, before mentioned, it will operate the seed-slide and other parts, as therein set forth.

A spring X, having one end secured to the end bearing F of the rock-shaft E and the other end secured to a bracket A, projecting from the seed-hopper, serves to return said shaft to its normal position after having been partly rotated by the knotted Wire or rope.

While I have described my check-rowing device as particularly applicable to cornplanters of the kind described by me in Letters Patent No. 404,318, still I do not wish to be understood as confining myself to that adaptation, as it is obvious that it can be em- L ployed in connection with any corn-planter or like implement using a rock-shaft substantially similar to that shown herein.

The cord secured to the upper perforation of arm P is extended rearwardly, as previously stated, to the foot-lever for pressing the furrow-openers of the planter into the ground. When the end of a row has been reached, the runner-frame of the planters is raised out of the ground by a hand-lever, and the arm Pis pulled back (one of said arms, as is of course understood, being on each side of the machine and operated in the same way) until a lateral stop 19 thereof engages the edge of arm G the arm P, it may be here stated, being provided with two of the lateral lugs, one for limiting its rear movements and the .other for limiting its forward movement.

After the arm is pulled back, as just described, the strings are secured tightly. This will throw the wire out of the fork as the bracket M, by the backward movement of the arm, is forced from its horizontal position to a perpendicular. In this manner the necessity of the driver alighting from the machine at the ends of the rows is avoided until after he has turned the same around.

From the foregoing-description the operation, construction, and advantages of my invention will be readily understood without requiring any further description.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. In a check-row corn-planter, the combination, with a main frame, of a supplemental frame secured thereto, an end shaft mounted thereon, a bifurcated bracket upon said shaft turning loosely thereon and carrying in its bifurcated portion a roller or sheave, alooselyarm or pawl provided with a downwardly and forwardly extending lug adapted to engage a projection upon the bifurcated bracket, and a cord secured to the upper end of the arm or pawl for operating the same, substantially as set forth.
