AUTOMATIC CHECK-ROW CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 657,246, dated September 4, 1900.

. Application filed April 9, 1900. Serial No. 12,076. on an.)

To ctZZ whom it may concern:

Be it known that I, LEROY J. LINDSAY, a citizen of the United States, residing at Seymour, in the county of \Vayne and State of Iowa, have invented a new and useful Improvement in Automatic Oheck- Row Corn Planters, of which the following is a specification.

My invention relates to the automatic check-row corn-planter shown and described in my applications for patents filed February 15,1900,Serial No.5,3l2,and February27,1900, Serial No. 6,685; and it consists of the improvements hereinafter'set forth, pointed outin my claims, and illustrated in the accompanying drawings to adapt the flexible carriage to be advantageously used for operating the seeddropping mechanism by means of a knotted wire.

Figure l is a top view showing the relative positions of all the operative parts. Fig. 2 is a view of the rear end of the carriage-frame and portion of the seat-support. Fig. 3 is a detail view of the swivel connection of the rotatable axle with the carriage-frame. Fig. 4 is an enlarged side elevation of the seed-dropping mechanism connected with a runner and a seedbox. Fig. 5 is asectional elevation and detail view of a seed-conveyer and valve operated by a weight. Fig. 6 isa top view, and Fig. '7 a transverse sectional View, of the seeddropping mechanism in the bottom of the seedbox. Figs. 8 and 9 are detail views of the operating-lever adapted to be actuated by a knotted wire for operating a seed-dropping valve in the bottom of a seedbox. Fig. 10 is a vertical longitudinal sectional view of the flexible carriage and operative mechan-.

ism connected therewith. Fig. 11 is a transverse sectional view on a line in front of the rotatable carriage-axle that has a swiveled connection with the carriage-frame and illustrates how the runner-frame is pivotally connected with a cross-bar that has pivotal connections with the side bars of the flexible carriage-frame.

A and A are the mating sides of a carriageframe. They are made of flat metal bars and coiled at their rear ends to produce hinge members A adapting them to be pivotally connected with. a cross bar 13, that is also coiled at its ends to produce hinge members B in such a manner that it can be placed on top of the side bars and pivotally connected therewith by means of screw-bolts 13, passed through the overlying hinge members, as shown in Fig. 2, to produce a three-sided flexible frame.

O is a rotatable axle in bearers O thatare swiveled to the side bars of the frame by means of plates 0 fixed to the outside faces of the side bars and extended up through coinciding apertures in the ends of a cross-bar D, through which the screw-threaded top ends of the bearers O extend and are pivotally secured thereto by means of nuts and riveting the extremities of the bearers on top of the nuts. Collars D interposed between the tops of the side bars and the ends of the cross-bar D, retain the bar elevated.

D is the bench or cross-bar of the runnerframe, to which the'front ends of the mating side bars A and A are hinged in such a manner as to allow vertical motion.

F is a bolster and seedbox-support pivotally connected with the cross-bar D and the tongue F by means of a bolt F and a nut on the bottom of the bolt, as clearly shown in Fig. 10.

H and H are mating bars fixed to the crossbar D, that is pivotally connected with the swiveled axle-bearer C and hinged to the bolster F at their front ends as required to allow Vertical motion. A flexible connection is thus produced between the carriage-frame and the bolster that allows lateral deflection from the line of advance, as required to facilitate turning about at the end of a field. The downward extensions of the bars H and H (shown in Fig. 10) are designed to be used as bearers for the rotatable shaft of a marker whenever desired.

J is a seat-support fixed to the cross-bar D, and J 2 is an additional seat-support pivotally connected with the cross-bar B at the rear end of the flexible carriage-frame, as shown in Figs. 2 and 10, or in any suitable Way that will not interfere with the lateral motion of the side bars of the carriage-frame and the auxiliary frame composed of the mating bars 11 and H the pivoted bar D, and the bolster F, that is pivoted to the cross-bar D K is a rock-shaft mounted in bearers K fixed on top of the pivoted cross-bar D.

K is a hand-lever fixed to the rock-shaft and provided with a spring-actuated pawl to engage a rack K formed on or fixed to one of the bearers K L is a lever fixed to the rock-shaft K. Its long arm is extended forward and adj ustably connected with an arm L that extends rearward from the pivot 0r bolt F, by means of a link L The short arm of the lever is extended rearward.

L is a collar on the rock-shaft K, and L is an arm extending rearward and adjustably connected with the short arm of the lever L by means of a screw-bolt m, that extends down through a bearing in the end of the arm L and a coinciding bearing fixed to the short arm of the lever L. A coil-spring m on the bolt and interposed between the said bearings allows vertical motion of the arm that extends from the collar L relative to the short arm of the lever L. A nut m on the lower end of the bolt m secures the spring in its place and also serves as a means for regulating the tension of the spring.

The ends of the pivoted bolster F are bifurcated and bent upward to extend horizontally in a plane above the rotating shaft F Seedboxes F are mounted on the bifurcated ends of the bolster and seedconveying tubes F connected with their bottoms to extend into the heels of the runners F.

N is a lever composed of two mating parts pivoted to the rotatable shaft F and fixed together by means of a block N and rivets to fasten them to the block. A ratchet-wheel N is fixed to the shaft F and a pawl N pivoted in the top of the lever to engage the ratchet-wheel,- as shown in Figs. 8 and 9. The lower end of the lever is bifurcated for the passage of a knotted wire that will actuate the lever to impart rotary motion to the shaft F at regular intervals of time and space as the machine is advanced to drop seeds into the furrows opened by the runners.

A rock-shaft P is mounted on the ends of the bolster F and has arms on its ends that carry direetion pulleys P to retain a knotted wire in line with the lever N, so that every time a knot in the wire contacts with the lever it will vibrate it as required to impart motion to the seed dropping mechanism in the bottom of the seedbox. A contractile spring P fixed to the lever and one of the branches of the bifurcated bolster F, retains the leverN in its normal perpendicular position.

P is a duplex fender fixed to the bolster to aid in retaining a knotted wire on the pulley P and P is a contractile spring that normally retains the free end of the latch P in engagement with a catch P fixed to the rockshaft as required to retain the pulleys in operative positions. A cord P fixed to the latch and to the drivers seat, as shown in Fig. 1, serves as a means for operating the latch to release the rock-shaft P and to stop the oper ation of the knotted wire relative to the seeddropping mechanism.

A toothed wheel R, fixed to the shaft F", engages the rotatable disk R under the bottom R of the seedbox F to impart intermittent rotary motion to the disk as required to bring its seed-cups successively into coinciding position with an opening in the fixed auxiliary bottom B, so as to allow seeds to drop into the conveyer F.

S is a valve pivoted in the conveyor F in such a manner that seeds dropped from the seedbox will be retained in the conveyer until the valve is operated. The top of the valve is inclined laterally and adapted to be en= gaged by cams S on the shaft F so that at every half revolution of the shaft the valve will be actuated as required to drop seeds from the conveyer into the furrow at the heel of the runner. An arm S having a weight S on its free end, will by force of gravity automatically reverse the motion of the valve to close it.

Corresponding seed dropping mechanism is connected with each seedbox and each end portion of the rotatable shaft F and con veyer F.

Having described the construction, functions, arrangement, and combination of all the parts, the practical operation and utility of my complete invention will beobvious to persons familiar with the art to which it per tains.
