UNI ED STATES PATENT F E- citizen ofthe United States,residing at Gale's- 4 5 jects upwardly from the bottom of the case A nois, have invented certain new and useful Improvements in Corn-Planter Oheck-Bowers,of which the following is aspecification,reference GEORGE w. BROWN, or

Application filed January a1, 1882. (Model.)

10 all whom 173 may concern:

Be it known that I, GEORGE W. BROWN, a

burg, in the county of Knox and State of Illibeing bad therein to the accompanyingdrawings.

This invention relates to improvements in corn-plan ter check-rowers of thatelassin which a stretched wire with tappets is used to impart movements to the seed-slides; and it consists in constructions and combinations hereinafter described and claimed.

In the accompanying drawings, which illustrate my invention, Figure l is a top plan. Fig. 2 is a top plan. Fig. 3 is a top plan. Fig. 4 is a sectional elevation in theline was in Fig. 2. Fig. 5 is a plan of the tappet-wire and a tappet secured thereto. Fig. 6 is a plan of the tappet-wire andsectional plan of the tappet secured thereto. Fig. 7 is a central section of a tappet-ball. Figs. I, 2,and 3 of the drawings show the working parts in different relative positions.

Referring to the drawings by letters, letter A represents a case with its cap or cover removed to expose to view the main working parts of my invention.

B is a head hinged or journaled to the bottom of the case A, and its outer end, 1), extended beyond the case for attachment of a rod or other device to transmit movement to the seedslides from the oscillations of' the head B. w Arms G C are hinged to the head B and extend from one side thereof, and arms D D are hinged thereto and extend from its other side. Each arm 0 G has a lug, a, at its free end, which projects laterally and outwardly therefrom, and each arm D D has a similar lug, d. The arms G C are straight from near their, mid-lengths to their free ends, and the arms D D are the same. A standard or guide, E, probetween the arms G G, and another, E, between the'arms D D. As the head B is 0scillated the free ends of the arms 0 G and D D are kept in straight paths by means of their respective side lugs sliding in contact with the side walls of the case A and their adjacentsides sliding against the standards between them. V

The parts hereinbefore described by letters are substantially the same as shown inan application for patent which I have made even date herewith, and as they are claimed in said application I do not claim them here.

The case A may be fixed upon the planter inany desired manner, whereby the pnsh bars be given a reciprocating motion by means of any desired orknown connection with the forked levers on, which the tappets on the stretched tappet-wire act.

G G are canrtrackbars, hinged one to each The parts being in relative positions as shown at Fig. 1, the push-bar F, advancing, will force the arm 0 backward beneath the cam-track G, which swings upwardly as the F F, which enter the ends of the case "A,inay

lug c on the arm 0 comes beneath it, and thus permits the arm 0 to slide forward without rising, as shown by full lines at Fig. 2. When the push-bar F has reached the end of its throw, as shown at Fig. 3, the end of the arm 0 will have passed from beneath the camtrack G, which cam-track will then fall to the position shown by dotted lines at Fig. 4. As the arm 0 isthrust forward, aslast described, the arm 0 will be thrust backward by the bar B, and its lug a will slide up the cam-track G, and thus elevate the end of the arm 0, so that the push-bar F may slide forward beneath it, as shown at Figs. 2 and 3. When the pushbar F is then retracted or slid backward it will not act on either arm 0 or 0, except to allow the arm 0 to drop to the bottom of the case A as it passes from beneath said arm. At the next forward movement of the pushbar F it will act upon the arm 0 and force it forward to pass beneath the cam-track G and the arm (J backward to be elevated by the cam-track G and permit the push-bar to pass beneath the arm 0, and so on continuously,

giving movement to the bar B and to the seed slides. The arms I) D are duplicates of the arms G, and are acted upon in the same manner by the push-plate when it is operated at that end of the case A.

The tappets are secured to the tappetwire as follows: Each spherical tappet I is formed with a cavity, 1', in one side, and a hole, '5, extending from the bottom of said cavity through said tappet. The wire J'is formed in sections united at each tappet. The end of one section is bent back to form an eye, j, and the ends of this section are then passed through the hole 1', so that the eye j rests in the cavity 6, as

shown, where it is securely held by coiling the .end of the wire upon itself, as shown at Fig. 6. An eye, It, on the end of another section of ,wire is then interlocked with the eye j, and held thereto by coiling its end upon itself, as I jg'oing; mannerarc not only cheaply and easily "made, but are firmly held in place and permit shown. Knots secured, to the wire in the forebending the .wire, asshown by dotted lines at lli g."5, 1sufficiently for readily winding it upon the spool, but notin amanner to allow kinks to form in the wire when slack.

What I claim as new is-- 1. .Ina check-rower, in combination with the head B and slidingarms G G, the hingedcamtracks G G,adapted to swing'upwardly to allow the arms 0 O to pass back below them,

and to fall to form inclines up which, the same arms slide to elevate them, substantially as and for the purpose specified. 1 v

2. In combination with the head B, with arms 0 C hinged thereto, and push-bar F, adapted to act alternately on said arms 0 G, the hinged cam-track bars G G, adapted to swingupwardly to allow the arms (J O to pass beneath them, and to fall to form inclines for elevating said arms, substantially as and for the purpose specified.

3. In combination with the head 13, having arms 0 O hinged thereto, with lugs c on their free ends, the cam-tracks G G, adapted to swing to permit said lugs c to pass beneath them, and to form inclines up which said lugs c slide to raise the arms C 0, substantially as and for the purpose specified.

at. A tappet-wire formed of tappets with a cavity in one side, which forms a seat for an eye on one section ofthe wire, which eye'is held in the tappet, substantially as herein described, and interlocked with an eye on the adjacent section of the wire, which eye is held by coiling the wire, substantially as and for the purpose specified.

In testimony whereof I affix mysignature in 7 presence of two witnesses.

GEORGE W. BROWN.
