LORENZO D. BENNER AND JOSEPH STAFFORD, OF GALESBURG, ILLINOIS,

ASSIGNORS TO GEORGE C. ALDEN ANITALONZO O. CLAY, BOTH OF SAME PLACE.

CHECK-ROW ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 266,341, dater1 October 24, 1882. Application filed August 3, 1881. Renewed June 10, 1882. (No modell.)

To all whom 'it may concern:

Be it known that we, LORENZO D. BENNER and JOSEPH STAFFORD, citizens ofthe United States, residing at Galesburg, in the county 5 of Knox and State of Illinois, have invented certain new and useful Improvements in Check- Row Attachments for Corn-Planters; and we do hereby declare the following to he a full, clear, and exact description of the invention,

1o suoli as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom pan yingdrawings, and to letters or figures of reference marked thereon, which form` a part of this specification.

This invention relates to check-rower attachments to corn-planters of that class used to transmitmotion received from a knotted checkrow chainl to theseeding devices ofthe planter;

zo and the invention consists in constructions and combinations hereinafter described, and set forth in the claims hereto annexed.

1n the accompanying drawings, which illustrate our invention, and in which the similar letters used as marks of reference apply to the like parts in all of the figures, Figure lis a top plan of a construction embodying our invention. Fig. 2 is a side elevation. Fig. 3 is a plan seen from below.

Referring to the drawings by letters, letter A represents a base-plate on which the working parts are mounted. The plate A may be attached to the planter in any desired manner which will permit the knotted cord to be guided 3 5 to the forked levers, as hereinafter described.

Letters B represent four forked arms or levers projecting radially from a shaft, O, which extends downward through and is journaled in the plate A.

D is a spur-pinion fixed on the lowerI end of the shaft C, so as to rotate therewith.

E is a pinion gearing with the pinion D and carrying a crank-pin, e.

F is a rocking or oscillating arm, journaled at its mid-length to the lower end of the shaft C, so that said shaft may rotate without imparting movement to the arm F, and so that said arm may be oscillated on the shaft O.

The crank-pin e passes through a slot,f, in the arm F. 5o G is an ordinary guide-pulley for the cord or wire H, which has ordinary knots, h.

l is also an ordinary guide-pulley.

In operation we prefer to place one of the devices shown in the drawings on each side of la two-row corn-planter, although it will be readily seen that a single device of the kind may be used, located centrally on the planter. As the machine is drawn along in close proximity to the previously-stretched knotted cord 6o or wire in the ordinary manner, each knot h will in turn act upon one of the forked levers B and give a quarter of a revolution to the shaft C and pinion D, thereby imparting a half revolution to the pinion E, which by its crank-pin e will oscillate the har F or give it a throw in one direction, and thereby impart a movement to the seed-slides, which may be connected with either end of the bar F by a rod, J. 7o

The rod J may be connected with the bar F in either of a series of holes, j", to regulate or adjust the extent of throw given to the seedslides of the planter.

It will be seen that the action of one knot h upon a lever B will bring the next lever B into proper position for the action of the next succeeding knot, and, further, that the impulse imparted to the shaft O by the action of each knot will impart an impulse or throw to the 8o seed-slides.

The crank-pin e is so arranged that at the termination of each throw of the seed-slides the crank-pin will be on its dead-point77 with relation to the bar F, and thus preventjarring motion or tilting position of the planter from operating the seed-slides; but we do not claim the last-named feature broadlyin this application, as it is shown and claimed broadly in an application of L. D. .Benner pending at same 9o time as this application.

Having thus described our invention, what we desire to claim as new is- 1. The combination,with the radially-forked levers B, which are acted upon by a knotted cord or wire, spur-pinion D,'and crank-pinion E, of slotted bar F, pivoted at its central part und adapted to beoseillated by the @rank-pinion for operating the seed-slides of zi planter, substantially :is specified.

2. The combination, with the radially-forked levers B, which are acted upon by 2L knotted oord or Wire, spur-pinion D, and crank-pinion E, of slotted bm F, centrally jonrnnled or pivoted on the snzii'b of the pinion G, and adapted to be osoillnted by the crank-pinion for operating the Seed-slides of n planter, substantially as Speeiiied.

3. rlhe combination, with the radially-forked levers B, which are acted upon by n knotted cord or Wire, Spur-pinion D, and zi slotted bar,

F, pivoted at its central part, of n pinion, E, provided with a crank-pin, c, arranged relatively to said bar F, als shown and described, whereby at; the rerniination of each throw of the seed-Slides it will be on its dead-point with relation to the bnr F, substantially as and for the purpose specified.

In testimony whereof we ni'ix our signatures in presence of two witnesses.

LORENZO I). BENNER. J USEPLI STAFFORD.
