WVESLEY W'ALTON, AND ISAAC WALTON, ALL OF CHECK-ROW PLANTER.

SPECIFICATION forming part of LettersFatent No. 289,696, dated December 4, 1883. Application filed July 5, 1883. (No model T0 (ZZZ whom it ntcty concern Be it known that I, LEVI J ODELL, a citizen of the United States, residing at Fairbury, in the county of Livingston and State of Illinois, have invented a new and useful Check-Row Planter, of which the following is a specification, reference being had to the accompanyingdrawings. 7

This invention relates to check-row planters; and its object is to provide a device of this class possessing superior advantages in point of simplicity, inexpensiveness, durability, and general efficiency.

In the drawings, Figure l is arear perspec tive view of the front portion of a corn-planter, showing my check-row mechanism in position. Fig. 2 is a detail perspective View of the gear-wheel mechanism. Fig. 3 is a sectional viewtaken through the rotary shaft that carries the crank-disk. Fig. 4 is a detail sectional view of the crank disk and pawl. Fig. 5 is a detail perspective view of the connection of the tappet-wire fork with the rockshaft.

Referring to the drawings, A designates the frame of the corn-planter, on which are mounted the seed boxes or hoppers B B, through which works the transverse reciprocating slide 0 in the usual manner.

D is a cross-bar that is secured on top the seed-boxes, and is provided with cross-pieces E E, arranged one at each end, and having bearings F F for the transverse main rockshaft G, to the ends of which are secured the forks H H, that are operated by the tappetwire to actuate the said rock-shaft.

The foregoing mechanism may be of any ordinary or suitable construction.

The rock-shaft G has a bearing in a plate,-

shaft will be carried around by the loose 4 wheel M. IVhen the tappet disengages from the fork H, the shaft G is brought back to its normal position by action of a spring, Q, on the fork, and the wheel J engages the wheel Min the opposite direction; but during this movement the wheel M will be merely turned on the shaft K and the pawl will slide over the face O,while the said shaft K will remain stationary until by the operation of the next tappet upon the forks it will be turned again by the Wheel M engaging the pawl. By means of this mechanism the rock-shaft has onlya rock motion back and forth, while the shaft K has a rotary intermittent motion. This rotary intermittent motion of shaft K of course turns the crank-disk L, the pin R of which enters alongitudinally-disposed slot, S, in the top end of a rock-lever, T, that is pivoted on a bracket, U, projecting from the cross-bar D, and is pro vided at its lower end with a slot, .V, that is connected with a slotted standard, .W, on the seed-slide G by a pin, X. By the movement of this rook-lever T, caused by the intermittent rotary movement of the disk L, the seedslide is-reciprocated.

The operation and advantages of my invention will be readily understood and appreciated. It is exceedingly simple and inexpensive in construction, and operates with superior efficiency.

The rock arms or forks IIH are preferably arranged to loosely turn on the rock-shaft G, which latter is provided with end pins, Y, that engage a shoulder, Z, on the forks, so that the rock-shaft will be turned by action of the forks. In this way the forks on therock-shaft will operate independently and alternately, as one will remain stationary while the other i'sin engagement with the pin to turn the rock-shaft. The crank-disk L is preferably provided with a ratchet-face, A that is engaged by a gravitypawl, B to retain the rotary shaft from backward movement while the rock-shaft is returnmg.

I am aware that check-rower mechanism has been heretofore constructed with a rotary shaft adapted to transmit its motion to reciprocate the seed-slide and operated by the rock-shaft,

the movement of the rotary shaft being interagainst rotary movement on the shaft, and

having the inner ratchet-face,the gear M, loose- 2o 1y arranged on the shaft between the disk I? and bar D, and having the outer ratchet-face, the spring acting on disk I to force it into engagement with gear M, the pawl B engaging portion A to hold shaft K from reverse 25 movement, and mechanism acting upon gear M to turn it alternately in opposite directions, substantially-as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in 30 presence of two witnesses.
