SPECIFICATION forming pari', of Letters PatentNo. 704,622, dated July 1 5, 1902.

Application filed June 3, 1901. Serial No. 63,005. (No model.)

To all whom zit may concern: On the end of this extension E is attached a Be it known that we, VROBERT E. DIAL and link ct, secured to the bell-crank arm 64X of MYLES E. GARWOOD, citizens of the United lthe ratchet-and-pawl mechanism of ordinary States, residing at Fontanet, in Jthe county construction. An upwardly-extending arm 55 5 of Vigo and State of Indiana, have invented a is also fastened to said extension E.

Rigidly secured to in Fig. 3, having two sets or series g' g2 of this beam or tongue D is an extension E, exthree teeth opposite each other and on the roc 5o tending rearwardly underneath the rear secface of said gear-wheel and recessed portions tion A to a point just forward of the axle B3. g and g3 between each set, as shown. Mesh- Ilo ing with this gear-wheel G is a small pinion H, mounted on the shaft I and having two lugs h h', adapted to enter the recesses g and g3 and two sets of teeth opposite each other and between said lugs. The pinion H when in operative position, as will hereinafter appear, remains stationary until the first tooth of one series-i. e., -strikes the lug, which, as before stated, normally remains in the recess which is at that time forward of the axle, when the pinion is rotated, and the two teeth of said pinion engage in the spaces between the three teeth on the face of the gear-wheel G, hereinafter mentioned. It is obvious from the above explanation that an intermittent motion of a rotary character is conveyed to the pinion. This pinion H is mounted on a suitable shaft I, running at right angles to the axle ofthe supporting-wheels. The end of the shaft I adjacent to the pinion is mounted in`a bearing .7', secured in a cross-beam .I by means of the keeperj'. The cross-beam is loosely mounted in the side beams of the rear or wheel section of the frame, so that said beam reciprocates therein. The other end of the shaft I is mounted in a bearing K, secured to the front beam of the rear section A. The bearingj is cylindrical in form, as indicated by the top plane View, (shown in Fig. 1.) the object being that when the beam J is reciprocated back and forth across the machine said bearing will be free to turn therein, thus permitting the shaft I to oscillate with respect to said beam J. The bearingj is also made in two sections, as shown,

in order that the shaft I may be readily removed therefrom. The forward bearing K of the shaft I is made in a manner such that the said shaft I can move freely from side to side therein.

It will be seen from the foregoing description that the pinion, and consequently the shaft I, can be thrown into and out of operation by operating the beam J through the eX- tension E andthe arm a'. The upper portion of the upwardly-extending arm a', before mentioned, passes through a suitable openingj4 (see Fig. 8) in the beam J and then through the opening 116 in the frame b', so that when the arm is raised the cam a2, before referred to, engages the side of the openingj4 and forces the said beam, -with the said pinion, in a direction away from the gearwheel G, and thus the pinion and its shaft are thrown out of operation by raising the extension E, this being brought about through the medium of the bell-crank arm 64X of the pawl-and-ratchet mechanism, as shown in Fig. 5. The shaft I is also provided with a transverse pin is, which projects out from either side of the same, for a purpose which will later-appear.

Mounted in a suitable support b5, secured to the frame A, is a lever N, one end of which is provided with a flattened portion fn, the flattened portion n being normally held in a depressed position by the spring ns and projecting to a point in the path of the pin 113 and the other'end pivoted in a clip n', mounted on the endl of a hollow cylinder (Shown in Fig. 4 and hereinafter described.) 'Ihe hollow cylinder n2 is provided with two longitudinal slots n3 and incases a rod n4, which has a pin m5 extending from either side thereof through the longitudinal slots ns. A coiled spring n.6 encircles the hollow cylinder n2 and exerts its force between the rigid clip n and the pin a5, thus allowing the rod to give when too great pressure is exerted upon it. A suitable guide nl, attached to the frame, is provided for the rod n4 to direct the same in a line with the seed-feeding chutes.

The construction just described constitutes the row-checking mechanism and is so arranged that it will operate in unison with the seed-feeding mechanism.

On the end of the shaft I is secured a crankdisk 1l, connected to the reciprocating plate or slide L by means of a link i. This plate is adapted to reciprocate between the bottoms of the seed-hoppers M M and the seedchutes O O', which run down through the drills, and is provided with two openings at each end thereof Z, Z', Z2, and Z3, two of these openings Z Z2 being covered, and hence shown in dotted lines in Fig. 1. The under side of -the plate L, between the two openings and at each end thereof, is provided with a recess Z4, fora purpose hereinafter described. The bottom of each of said hoppers is provided with two openings m m', having between them a solid portion 'm2, which is sufiicient in size to register with the seed-openings in each of said drills and serves as a cut-olf.

The seed-feed chutes, hereinbefore referred to and lettered, respectively, O O', are each provided with oscillating valves o o, o being pivoted at o2 and o at o3. The valves are arranged substantially as shown in Fig. 4, so that the entire amount of grain to be planted at each operation of the plate L will be held in the chute and dropped all at once, thereby preventing the scattering of the grain along the trail.

In operating the device the operator lowers the rear end of the shoes or furrow-openers by advancing the hand-lever Z of the pawland-ratchet mechanism, which operation also throws into place the seed-feeding mechan-A ism, hereinbefore described. The planter is then drawn forward, and for each revolution of the ground-wheels two droppings of corn are planted. With each dropping the checker mechanism is operated, so that each cross-row is marked thereby. The operator having planted one row of corn the operating mechanism is thrown out of operation. Thelplanter is then turned around and the shoes or furrow-openers placed in a line with marks made by the checker in the last hill of corn, 4thus keeping the rows in a line. Before starting, however, the gear-wheel G must be turned by hand, as before stated, until the tooth .fr is just in position to engage the lug nearest it IOO IIO

on the pinion H, the seed-operating mechanism having been thrown out of operation when the gears were in the position shown in Fig. 3 of the drawings.

The size of the wheels and gears may be changed so that the seed-feeding mechanism will operate at dierent intervals without departing from the spirit of our invention.

In Fig. 7 of the drawings the gear-wheel G is represented as being divided into four equal parts on the lines R and S. This arrangement is provided so that the recessed portions may be removed and portions supplied having teeth similar to those at gf.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s
