CHECK-ROWER FOR CORN-PLANTERS SPECIFICATION forming part of Letters Patent No. 280,641, dated July 3, 1883.

Application filed April 14, 1883. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES S. LocKE, a citizen of the United States of America, residing at J oliet, in the county of VWill and State of Illinois, have invented certain new and useful Improvements in Oheck-Rowersfor Corn- Planters, of which the following is a specification, reference being had therein to the accompanying drawings.

Myinvention relates to an attachment for that class of corn-planters in which the slide for the seed-boxes is operated by a cable fastened at each end of the field and having knots at regular intervals engaging with a vibratable member of v the planters attachment, by which reciprocating motion is transmitted to the seed-box slide; and it consists of the novel devices and combinations of devices, hereinafter' described and specifically claimed.

In the accompanying drawings, Figure 1 represents a plan view of the check-row attachment; Fig. 2, a longitudinal vertical section through the center of the same; Fig. 3, an edge view of the attachment; and Fig. 4, a longitudinal section of the connecting-bar.

Corresponding letters in the several figures of the drawings designate like parts.

A denotes the main or bottom plate of the frame of the attachment, consisting of a seg mental plate, a, that upon its radial ends has projecting strips 7) and c, to one end a project ing arm, (I, and is cast solid with a central bar, 0, which to one end has lugs y, and to its opposite end a pulley, f, and stud for guiding the knotted cable B. V Upon strip 1) is fitted the strip h of another segmental plate, 0, and is secured thereon by two dowels, t, of strip h, fittinginto sockets of strip b, and by a screw, that is tapped into strip 1).

The plates A and C have each a hub, Z, that is concentric with the curve of their segments, and into each of such hubs Z is pivotally secured the trunnion Z of a Y-shaped lever D or D, by means of a washer, m, secured upon the end of such trunnion by a screw, n. The strips 1) and h hold the plates A and O the proper distance apart for the Y-shaped levers D D to be separated just far enough for the cable B to pass freely between, but to exclude the D are chamfered, and their trunnions Z are about one-third of the entire length of such levers distant from that forward end, and are arranged to be central to the line on which the knotted cable B is guided through the attachment.

To near its pointed end each lever D D has formed a trunnion, p, to engage with the eyes of the bifurcated end of connecting-bar E, that is made in two halves secured together by dowels and a bolt, g. This bar E, holds the two levers D D in line with each other, and itsopposite bifurcated and eyed end is coupled with either of a series of trunnions, 1', that project from the sides of the end of a lever, F. This lever F is pivoted upon arm d of plate A by a fulcrum-bolt, s, and its rear end has a series of holes for pivotally coupling a bar or rod at the necessary distance from the fulcrum of such lever, according to the length of stroke desirable for the seed-slide lever.

At about half distance between trunnion Z and the rear end of lever D such lever D is provided with a boss for pivotally securing by a screw, 2, a small roller, u. A latch, G, is pivoted with one end on a screw, 1), tapped into the end of plate 0. This latch, by a leaf-spring, H, is depressed to bear upon roller u, and has inclined edges, that tend to lock the levers D D, on either end of their stroke, with sufficient resistance to require a certain amount of side pressure before such levers can be started toward the opposite end of their stroke.

Projecting and flaring guard-lugs w are formed to the corners of the rear ends of levers D D, that will prevent the knotted cable from leaving its prescribed course.

The plate A of this check-rower attachment is secured in proper position upon the middle or either side of the corn-planter frame by bolts passed through holes in strip 0 and through arm (I, or in another convenient manner, and the lever F is to be suitably connected by a rod or bar with the lever or .levers that operate the seed-box slides.

The knotted cable B, after being anchored to the field, can be readily inserted from the side of strip 0 between the levers D D, and then placed between pulley f and stud g at one end of plate A,'and between guide-lugs 1 of knot-s 0 that are formed or secured upon such 1 the other end of plate A, when, as the machine cable. The pointed forward ends of levers D l is being moved over the field in the direction indicated by the arrows, a knot, 0, of such stationary cable will. come in contact with the edges of levers I) D, and while the cable itself has a free passage through the space between such levers, the knot will have to followthe relativcly'angular lines of these levers, thereby creating a side pressure that will overcome the resistance of spring-latch (l, and will vibrate the levers l) l) to swing to the opposite end of their stroke, alter which movement the knot 0 will have a free passage be tween guard-lugs w and guide-lugs 3 The levers D I) thus having attained their opposite position, the next knot 0 of cable 1 will. now be guided to come in contact with the edges of the opposite side of levers D l), which will tend to swing the levers backto their iirst position, and in this manner successive knots will come in contact alternately with the opposite edges of levers l) l), and will vibrate these levers to and fro withintermittent quick strokes. The vibrations of levees l) Dbeing in'iparted to lever F byconnecting-barE, such lever F again, by any suitable connection, is to be coupled with the lever or armthat operates the seed-box valves or slides in a manner that each movement ol the levers D I) will tend to drop a seed.

Vith the above device the seed-box slide or valve is thus operated by a quick short stroke. so essential in the correct dro )ping of corn.

The movements of the attachment are very easy and yet positive. I ts construction is very simple and inexpensive, and it has no parts that can readily wear out or break, and when accidentally broken can be easily replaced 1 a duplicate piece.

These cheek'rower attachments can be applied to all. styles of corn-planters, and can be made right and left, to be secured to either one or both sides of the machine.

I am aware that a cam composed of two parts, between which the check-row cable passes, and the knots adapted to act on the edges of such cam in. alternate order to vibrate the same, is old, and such I do not desire to claim; but

\Vhat I claim is 1. In a check-rowel. i'or corn-planters, the Y-shaped levers 1') I), each pivoted independ ently and axially in line with the other, and each having cxteriorly to its forward end a trunnion, p, and both levers being coupled to work in conjunction by and to one bifurcated which connects with lever F, that again is to connect with the seed-box slides, all substantially as and for the purpose set forth.

2. Theherein-described check-rowerior cornplanters, consisting of base-plate A, having cable-guides and cap-plate (J, the Y-shaped levers l.) l), pivoted between such plates, each independent of and axially in line with the other, and with an open space between, such levers l) 1) having each a trunnion, p, to couple with one end of bar 1*], that connects with lever F, and lever I), having a stud or roller, 'u, engaging with pawl G, thatis pivoted to cap-plate C and is depressed by spring H, the whole being constructed and arranged, substantially as (hscribed, to operate as specified.

In testimony whereof I at'lix my sigimture in presence of two witnesses.
