CORN-PLANTER `CHl'iCK-ROWER.

j .SPECIPICATICN forming part of Letters Patent No. 303,169, dated August 5, 1884.

Application filed January l2, 1683. (No model.) l

To all whom t may concern:

Be it known that I, JAMES C. LEIDY, a citinen ofthe United States, residing at Galesburg, in the county of Knorr and State' of Illinois, have invented certain new and useful Improvements in. Gern-Planter CheclrItowe1s; and I de hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference .marked thereon, which forni a part of this specification.

This invention relates to corn-planter checkrowers of that class in which the check-row devices are actuated by knots or ta-ppets on a stretched wire; and the invention consists in constructions and combinations hereinafter described, and set forth in the claims hereto aunexed.

In the accompanying drawings, which illustrate my invention, Figure l is a top plan. Fig. 2 is an end elevation. Fig. 3 is a plan of one end of the device seen from below. Fig. is a front side elevation. Fig. 5 is a perspcctiveof the central part of the planter slidebar and connections of the check-row devices thereto. Fig. 6 is aside elevation of two sections of the clieelorow chain or tappeti-wire.

Fig. 7 is a sectional. plan of the wheel which .ierent figures, A represents the ordinaryhar,

to each end of which similar devices are attached, as shown at Fig. l, but only one of which need be described herein.

B is a T-shaped head, fixed to the end of bar A, and provided with ordinary guidepulleys, D D', for the ordinary tappet-wire, C.

D is a heiter-wheel journaled to the outer end of the head B, and in gear with a smaller imiter-wheel, D", which is journaled to the upper side of head B. Ordinary forked arms, E, are radially adjustable on the wheel D, and are held after adjustment by bolts e, which pass through slots in the arms E and into the wheel D. By adjusting the arms E, the proper length of time of Contact of the tappcts o on the wire C with the forked arms E maybe regulated, and by said arms being bolted to wheel D, if either gets broken, it may be replaced by a new arm.

F is a frame, with arms f, which are hinged to the bar A, and an arm, f', to which a friction-wheel, G, is journaied, and a rear projecting arm, f, with a spring, f, between it and the bar A, which spring tends to hold the rim of the wheel G in frictional contact with the side of the wheel D. The side oi' the wheel D next the wheel G has depressions g, one between each pair of arms. E, or in such positions that aftera tappet on the cheek-row wire has acted on one of the forked arms E the wheel G will be pressed by the springf into one of the depressions q with sufficient force to hold the wheel G and other parts of 7o the device, and thereby prevent accidental movement of the planter seedslides from jarring or tilting of the planter, and also hold the wheel D in such position that one of its forked arms E will always be in proper position for the action of a tappet c. W'hen a tappct c acts on the wheel D, the spring f will yield, and allow the wheel G to yield baekwardto permit movement ofthe wheel D.

II is a lever, pivoted, as shown, tothe bar A.

I is a connecting-rod. The miter-wheel D has av crank-pin, (Z, on which a sleeve, d', is eccentrically journalcd, and held, after radial adj ustnicnt, by a nut, d", on the outer end of the crank-pin. The eonnectingrod I is hinged to the upper end of' the lever I-I, and may be turned over to engage a strapy, on its free end with the eccentric on the wheel D at either side of the machine, as shown by full and dotted lines at Fig. l.

J is an arm, which may be adjusted higher and lower in a slot, 7L, in the lower end of the lever H, and held after adjustment by a nut, ii.

J is a sleeve cccentrically journaled on the arm J, so that it may be adjusted radially on the arm J, and held after adjustment by a nut, j, on said arm J.

K is the central part of the ordinary connecting-bar between the secdslides of the planter.

IOO

L is a plate, with a vertical slot, Z, in each 1 end, through which bolts l pass to secure it to the Abar K, as shown. adjusted vertically, and held after adjustment by the bolts Z.' Arms L project upwardly from the plate L, between which arms L the eccentric J operates. By adjusting the sleeve J radially on the arm J the device may be made to give a very exact throw to the seedslides in either direction, and by adjusting the armv J vertically on the lever H the extent of throw of the slides may be regulated as desired. rIhe extent of throw of the seedslides may be more finely adj usted by 4adjusting the eccentric d on the crank-pin d. The arm J is long, so that it may seat properly in the arms L in planters of different construction.

The operations of the device further than hereinbefore described will be evident to any one skilled in the art. In passing in one direction across the field the connecting-rod I is connected with the miter-wheel D at one side of the machine, and in passing across in the opposite direction it is connected with the ruiter-wheel at the other side of the machine, whereby the devices at one end of the bar A remain stationary while those at its other end are in operation. Each tappet, in operating on a forked arm, E, brings another forked arm into proper position for the action of the next tappet. My tappet-wire, with tappets or knots c, is formed as shown at Fig. 6. The sections c of the wire are united by the tappet c, which is a link with an enlarged end, c, through which the end of one section of wire passes, and has a head, c", formed thereon, which holds the wire therein and forms a swivel. VThe end of the other section of wire is passed through the other end of the link or tappet c, and bent back upon itself, and secured by ceiling the end upon the main portion, as shown at same figure. I thus unite the sections of wire and the tappet, so as to form a universal-joint connection between the sections of wire, and also a swivel, to permit iexure in any direction between the sections of wire, and to relieve the wire from any torsional strain.

What I claim as new, and desire to secure by Letters Patent, is-

l. In combination with the tappet-wire and The plate L may be l the miter-wheel D, having radial forked arms E attached to its disk, -the miter-wheel D', connecting-rod I, and lever I-I, connected with the seed-slide-operating bar, substantially as and for the purpose specified.

2. In a check-rower, in combination with the ruiter-wheel D, having forked arms E attached to its disk, lever II, connected with the seed-slide bar, connecting-rod I, having strap t' on its end, the vimiter-wheel D, having -a crank-arm, with an eccentric sleeve journaled thereon, substantially asfand for the purpose specied.

3. In combination with wheel D, having forked arms, wheel D', having crank-arm, and lever H, for operating the seed-slides, the connecting-rody I, hinged to lever H, and adapted to engage with 'wheel D on either side of the planter, substantially as and for the purpose specified.

4. In a check-rower, in combination with the seed-slide bar, connecting-rod I, adapted to be operated by suitable mechanism connected wit-h a tappet-wire, and lever II, the arm J, having sleeve J eccentrically journaled thereon, substantially as and for the purpose specified.

5. In a check-rower, in comblnation with a tappet-wire and a wheelD, having forked arms E, the yielding friction-wheel G, adapted to act in depressions in one side of wheel D, substantially as and for the purpose speciiied.

6. In combination with forked lever-carrying wheel D, with depressions g in one side, the yielding friction-wheel G, adapted to enter said depressions, substantially as and for the purpose speciied.

7. A check-row tappet-wire formed of scctions c', one of which is provided with au eye formed by coiling its end upon itself, and the other provided with a head and an interposed link joined to sections, substantially in the manner shown.

In testimony whereof I affix my si gnature in presence of two witnesses.
