GEORGE D.'HAWORTH, OF DECATUR, ILLINOIS.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 427,234, dated May 6, 1890.

Application filed October 17, 1889- Serial No. 827,304. (Model) To aZZ whom it may concern.-

Be it known that I, GEORGE D. HAWORTH, of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Corn-Planters, of which the following is a specification.

My invention relates to check-row cornplanters, in which a knotted line is used to actuate the dropping mechanism, and it includes a check-row movement and an anchorstake,.both having peculiarities of construction and operation, as will hereinafter appear. The movement is actuated positively and entirely by the knots of the check-row line, each operation leaving all the parts in position for another operation without the intervention of reacting springs or weights. It may be operated equally well from either side, which adapts it perfectly for a center movement, and its connection with the shake-bar of the planter is simple and direct. It comprises, essentially, a pair of L-levers pivoted at op-. posite points relative to the normal position of the check-row line, the long arm of each lever being adapted to the line and the knots thereof, and the short arms being connected with a bar having a roller or boss that acts on a third L-lever connected with the shakebar. The pair of levers extend obliquely toward the path of the line, but in contrary directions, and when one is actuated by a knot the connecting-bar carries the other into position to receive the action of the next knot and at the same time imparts an operative motion to the shake-bar through the third or odd lever. Though the three L-levers and the single connecting and interactuating bar form the gist of that part of the invention embodied in the movement, there are details of construction and combinations of parts in the levers, bar, and adjuncts that are of utility and novel, and such will be set forth in the specific description and in the claims.

The anchor-stake comprises a stake and a pair of arms extended from the stake in opposite directions, and having each a rectangular bend or turn extending in the same or nearly the same direction with reference to a line drawn longitudinally through the arms, the object being to provide a simple stake, easily inserted, that willretain the Wire while the planter is moving to or from the stake across the field, and that will automatically release the same when the planter moves along the ends of the field in either direction preparatory to turning around.

In the drawings accompanying and forming a part of this specification, Figure 1 is a plan of a fragment of a corn-planter, showing the manner of using my invention and its relation to the planter. Fig. 2 is a perspective view of the anchor-stake. Fig. 3 is a diagram showing in skeleton the essential elements of the check-row movement. Fig. 4 is a top View of the complete movement. Fig. 5 is abottom view of the same. Fig. 6 is a top view of the movement with a stroke half completed. Fig. 7 is a sectional view on broken line so in Fig. 6.

The spider-frame 8 provides bearings for the different parts of the movement. It is placed centrally on the planter. It has a stud 8 and aslot S to receive a securing-bolt, the bolt and the stud coacting to make a simple and effective attachment, and it has the rib 8 which supports and braces the bearing for the odd lever. Guide- loops 9 and 10, formed of continuations of arms of the spider, receive and guide the check-row line 11. Lever 1 pivots on pin 44, and'has the short arm 2 connected pivotally with bar 5. Lever 3 pivots on pin 43, and its short arm 4 connects pivotally with the opposite end of the same bar. The bar 5 has roller 5, which is secured to the sliding plate 23, and the plate is held in position by bolt 22. The odd lever 6 has the bifurcated arm 6, that is adapted to roller 5, and it has the adjustable extension 24, which carries the stud 26 and is secured in any desired position of adjustment by bolt 25. Stud 26 of the extension of the odd lever acts in a slot of bracket 7 and imparts motion to the shake-bar 7. (See Figs. 1 and 3.) Bar 5 is provided on its under side with the normally-oblique rod 18, which connects pivotally with the bar, extends through a slot in block 8 of the spider, and has the beveled collar 21, the spring 19, and the key 20. The arms 1 and 3 have adjuncts and peculiarities as follows, reference being had more particularly to Fig. 7: The arm 1, having the various deviations shown, terminates in bevel 1" and a rectangular extension. An independently-movable dog 29 forms with arm 1 a bifurcation in which the line operates. An end 28 of dog 29 slides in a groove in arm 1. A recess 27 admits a rod 33, which carries a spring 34, interposed between lateral projections of the arm and of the dog. Arm 3,terminating in beveled portion 3,-is provided with dog 32, which has the sliding end 31 and the recess 30. The rod 35, acting in the recess, carries spring 36. Arm 3 is held on pin 43 by cap-plate 38, which fits against the strut 39, (shown in Fig. 7,) and is held by bolt 41. (Seen in Figs. 4, 5, and 6.) A similar capplate 37, with the assistance of strut 40 and bolt 42, retains the arm 1 on pin 44. The anchor-stake 13 has the bracket 14, secured by bolt 17. Its arms extend in opposite directions, and they are provided one with hook 15 and the other with hook 16.

In operation the stake is forced into the ground by foot-pressure on the bracket and with an arm presented in the direction of the motion of the planter across the field, the hook of the arm being presented in the direction of the motion of the planter along the end of the field, and the tension-tester carrying the line is caught on the hook, as seen at 12 in Fig. 1. Then as the planter returns and moves along the side of the field in the direc-' tion of the hooks projection the tension-tester will become automatically detached. The levers of the movement (1 and 3) act alternately in opposite directions. The knots strike the arms with a tendency to force the dogs toward the respective pivots, but as the strokes are completed the direction of the exertion of the force is relatively changed, and the springs are forced to yield to permit the passage of the knots. The spring 19 (seen only in Fig. 5) tends to hold the parts of the movement from casual motion and insures completion of strokes. The adjustment of extension 24 of 1. A check-row movement comprising a pair of reversely arranged and reversely conformed levers, a connecting-bar for the pair of levers, and a spring presented obliquely to the motion of the connecting-bar, as set forth.

2. A check-row movement comprising a pair of reversely arranged and reversely conformed levers, a bar connecting the pair of levers, and a third lever actuated by the connecting-bar and adapted to the shake-bar of a planter, as set forth.

3. A check-row movement comprising apair of reverselyarranged and reversely conformed levers, a bar connecting the pair of levers, a third lever actuated by the connectin g-bar and adapted to the shake-bar of a' planter, and a spring presented obliquely to the motion of the connecting-bar, as set forth.

4. A checkrow movement comprising the spider having the guide-loops, the pair of levers connected by the bar, and the odd lever actuated by the connecting-bar and adapted to the shake-bar of a planter, as set forth.

5. The ch eck-row movement comprising the pair of levers, the bar connecting the pair of levers, the roller on the connecting-bar, and the odd lever having the bifurcated end adapted to the roller, as set forth.

6. In combination with check-row arm 1,

dog 29, having sliding termination 28 and recess 27, bolts 33, extending through lateral projections of the arm and the dog, and spring 34 on the rod between such projections, as set forth.

7. An anchor-stake comprising a stake and rectangular hooks thereon arranged to be presented in opposite directions with reference to the check-row line, as set forth.

8. An anchor-stake and arms on the stake extended in opposite directions therefrom and having rectangular hooks presented in the same direction, as set forth.

In testimony whereof I sign my name in the presence of two subscribing witnesses.
