SPECIFICATION forming part of Letters Patent No. 445.397, dated January 2'7, 1891.

Application filed May 6, 1890. Serial No. 350,810. (No model.)

.To aZZ whom it may concern.-

Beit known that I, AUSTIN O. EVANS, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Check-Rowers, of which the following is a specification.

My invention relates to check-rowers for corn-planters; and it consists in the various constructions and combinations of parts hereinafter described, and set forth in the claims.

In the accompanying drawings, Figure 1 is an elevation of a check-rower device embodying my invention. Fig. 2 is a plan of the same, only so much of the supporting mechanism being shown as is necessary to a proper understanding of the device. Figs. 3 and 4., respectively, are detail views, in elevation, of some of the operatin parts shown in different positions. Figs. to 12, inclusive, are detail views of the various parts, which will be more fully referred to hereinafter. Fig.13 is a sectional view on the line a; in

' Fig. 2.

tion of the corn-planter frame to which my improved device is attached.

B B is the frame of the check-rower device, which supports the operating mechanism thereof." The frame B B is connected to the bar A through the medium of a connectingplate 0, which plate O is provided with two wings O 0 as shown in Figs. 8 and 9. The win O is provided with a series of serrations a, adapted to be engaged by a series of similar serrations on a flange or projecting car B of the frame B 1-. This car or flange B is provided with an elongated opening 13 through which is extended a fastening-bolt a, the fastening-bolt a being also adapted to pass through the wing C of the plate 0. The wing G of the plate 0 is provided with a projecting flange a adapted to extend over the top of the bar A, the wing O being arranged at the side of said bar and bolted to the same by suitable fastening-bolts a By this construction the frame B B is secured firmly to the bar A of the plantei frame, the longitudinal serrations a in the respective parts B and O being adapted to hold the said frame against any lateral or torsional movement of the same, the elongated opening B however, being adapted to permit of a longitudinal adjustment of the parts to bring the frame B B in its proper relative position with the bar A to cause the operating-lever to be acted upon at the proper point in the manner hereinafter more fully described.

D is the operating-lever, which is preferably formed in two parts I) and Z), the upper part 1) being bifurcated in the usual manner, as shown in Fig. 2, to be engaged by an operating-wire y y, the lower part being formed with an elongated opening 11 having in one of the walls thereof a projecting lug or shoulder b. The elongated opening 19 is adapted to receive therein a ratchet-wheel 0, arranged on one side of a beveled driving-gear D, the proj ecting shoulder or in g being adapted, when the operating-lever is in its normal position, as shown in Fig. 4, to engage with the ratchetteeth of said ratchet-wheel c and turn said wheel as the lever is moved in a forward direction, as indicated by the arrow in Fig. 4, the elongated opening 12 being adapted to permit of a backward movement of said lever around said ratehet-wheel and independent thereof. The operating beveled gear D is also provided on its back with an annular flange 0, having stop projections 0 arranged at intervals around the periphery thereof, preferably four in number.

Arranged above the annular flange e is a movable catch 0 pivoted at c to the frame 13 1-3. On the lower portion b of the operating-lever D is a projecting cam-faced 'lug b adapted to rest under the movable catch '0 and hold it away from the annular flange c, as shown in Figs. 3 and 42, the said camfaced lug if being adapted, by reason of its peculiar formation, to pass under the hookshaped end of the catch c as the lever is moved in the forward direction, thus releasing said catch and permitting it to drop into the position indicated in dotted lines in Fig. 4, and thus engage the stop projection c and form a stop for the gear D.

The operating-gear D is adapted to turn on a sleeve d, secured firmly to the frame B B bya fastening-bolt d, which passes through said sleeve, one end of said sleeve being adapted to rest against the frame B B and the flS other against a washer or collard the bolt at being adapted to pass through said collar or washer, and thus bind the parts all firmly together. The hub of the operating beveled gear D is made of sufficient length to fit snugly between the collar (1 and the frame B. The face side of the' operating-gear D is formed at the center or about the hub thereof with a ratchet (Z similar in shape and size and number of teeth to the one c on the opposite side of said gear, the pitch or inclination of said teeth being arranged in the opposite direction from those on said ratchet c. A pivoted pawl d, pivoted to the main frame B B, is adapted to engage said ratchet and hold the gear D against any backward movement.

Located on the top of the frame B B and adapted to turn in a suitable bearing 6 thereon is what I will term the crank-gear D which engages with the operating-gear D. This crankgear D is preferably formed with an extended hub fitted to the bearing c, and is held in position in its bearing by a collar 6 and bolt (2 The. upper portion or back of the gear is provided with a series of serrations 6 which are engaged by similar serrations on a crank-arm e" having a wrist or crank pin 6 Thecrank-arin is provided with an elongated opening c, through which the bolt c passes. The lefngth'ofthe hub of the gear D? being such that when the bolt 0 is drawn tightly against the collar c and crank-arm e, the parts are all held firmly together, while the gear. DF: is adapted to turn freely in its bearing e.

The crank or wrist c is connected to the operating-lever E of the planter through the medium of a two-part link-connection E, the parts of the link-connection being preferably formed of a screw-threaded rod f, having a hook-shaped projection f, adapted to pass through a suitable opening in the operatinglever' E and be secured therein by a pin or split key f*, a screw-threaded portion f 3 being adapted to engage in an internal screw-threaded hub or sleeve f of the other portion f of said link-connection, the part f being journaled on the crank-pin c and preferably bent or curved, as Sl1OW-l1,t0 bring the hub or sleeve f from the, connecting portion f so that the one stroke of the drop-lever E in one direction.

The check-Wire y y is adapted to pass around supporting sheaves or pulleys g, g,

and g? in the main frame in the usual m an-' nor, so that the knots or projections thereon shall engage the operating-lever D. As the machine is advanced, the operatinglever D is thrown by said knots or project-ions in a forward direction, carrying with it the operatbig wheel D, the movable catch 0 being held away from the stop projection c by the camfaced projection as in the manner before described.

Before the operating-lever reaches the limit of its stroke it passes from under the movable catch 0 which being thus released drops down upon the annular flange c and engages with the stop'projection 0 thus forming a positive stop for the operating gear and lever. The

lever has by this time been sufficiently ad-v vanced'to, permit the check-wire to be released therefrom, after which the lever is turned to its normal position by a spring h, secured at one end to. a projection hon said lever and at the other to an adjustable arm 71 secured to the frame B. It will thus be seen, as before stated, that each movement of the lever D produces a complete stroke of the droplever E.

It will be seen that as thus described I provide a check-rower attachment which is at once simple, complete, and effective in its operation.

By the arrangement described for attaching the supporting-frame to the main planterframe the operating-lever may be adjusted forward or back in positive alignment, so that the dropping will always come in check.

By the adjustable two-part link-connection I E, as described, and the crank-arm and crank:

gear the parts may be adjusted to produce any desired stroke of the dropping-lever.

Having thus described my invention, I claim+ 1. The combination, with a supportingframe and an operating-wheel j ournaled thereon, of a bifurcated lever having an elongated opening adapted to surround a ratchet on said operating-wheel, and a projecting shoulder in said opening formed integral with the walls of said opening, adapted to. en gage. said ratchet, substantially as specified.

2. The combination, with an operatingwheel having the ratchet-teeth and an annular flange with stop projections thereon, of a his furcated operating-lever having anelongated opening and an engaging projection in said,

opening form ed integral With the walls there-V of, a movable catch adapted to engage. wit-h said stop projections, and a cam-.faced'lug on said lever to hold said catch normally out of engagement with said stop projection, sub.- stantially as specified.

3. The combination, with an operating-1 wheel having oppositelyinclined ratchetteeth on each sidethereof, of a bifurcated le-. ver with an elongated openingadapted tosu round one ofsaid ratchets, a projection in one of the walls of said opening to engage. said ratchet, stop projections on said Wheel, and a pivoted catch adapted to engage said fro stop projections, means on said lever for normally holding said movable catch out of engagement with stop projections, and a pivoted pawladapted to engage with the ratchet 011 the opposite side of said operating-gear, substantially as specified.
