CHECK-ROWER.

SPECIFICATION forming part 0f Letters Patent No. 312,179, dated February 10, 1885.

Application tiled March 14, 1884.

To @ZZ whom it may concern.-

Be it known that'I, LORENZO D. BENNER, of Peoria, in the county of Peoria, in the State of I-llinois, have invented an Improved Check- Rower; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which- Figure l represents a plan view of the device; Fig. 2, a vertical longitudinal section through the center; and Fig. 3, adetail.

This invention is in that line ot check-rowers for corn-planters in which a knotted wire or cord intermittently reciprocates a 'bifurcated lever whose movement operates, through intermediate mechanism, the feed-slide of the planter, and relates to the construction of an improved device for converting the moveinents of the hifurcated lever into a positive, selflocking, intermittent reciprocation of the feed-slide.

My invention for this purpose consists, essentially, of two laterally-contiguous oppositely longitudinally reciprocating bars, having at one end of each a bent channel, in which the hooked end of a rod, connected with the bifurcated lever, can slide 'from the channel of one bar to the channel of its neighbor when said rod is pushed in one direction, but, when it is pulled in the opposite direction, engages with the notched bottom of said channel and moves the bar back with it, at a forward movement passing from one bar to the other, and at the return-stroke bringing the bar back with it. Since there is a bifurcated lever at each side of the planter, there are of course two hooked rods and channels at each end of each bar.

In the drawings, R is a portion of the transverse beam, at the ends of which are arranged the bifurcated levers, (not showin) and at the center of which is my device.

s s are the hooked rods before mentioned, whose ends (not shown) are pivotcd to the bifurcated levers, by which they are given, through the agency of the knotted wire and a retracting-spring, a reciprocating movement.

The bars A are formed at each end with a groove of the shape shown, of varying depth,

(No model.)

l whose ends open out through the contiguous sides of the bars, as shown iu the drawings. At the bend ot' each of these channels a, I usually have a vertical hole, a', through the bar thereat, from the side ot which, toward the end of the bar, the bottom ot' the channel a slopes downward and outward, while at the opposite side of said hole the bottom of the channel is depressed and slants upwardly and outwardly therefrom. These channels or grooves a are so conformed that one end of one opens into one end of its neighbor whenever the bars A are at their opposite points of reciprocation. By this means the hooked end of the rod s can slide from the hole a of one channel up its inclined bottom and the inclined bottom of the contiguous channel until it drops into the hole a ot' the latter. Vhen, however, the said hooked end is drawn in the opposite direction, it engages with the elevated side ot' the hole a in which it is and pulls the bar A along with it. I sometimes remove the delta-shaped projection that lies between each channel a and the contiguous faces o f the bars A, for, practically, there is no necessity in having the same; and not only this, but should the two bars Amake, by any means, only half a stroke, the two projections would form an obstruction upon which the hook of the rod s might catch, and the ma- `chine be thereby injured.

To give the bars A a reciprocating move ment in opposite directions when one only is reeiprocated, they are connected to t-he cen.

oscillation of the latter shall communicate tothe former an exact semicircular reciprocation. Since the teeth at one side alone of the pinion G mesh with the gear D in both its semi-revolutions, the teeth at its other side are superiiuous, and I therefore form said pinion IOO mutilated, as described. This pinion G is pivotally secured upon the laterally-projecting arm Q, cast as a part of the plate P. Upon said plate rest the bars A, which are kept in place thereon by means of the upwardly-projecting rims Pf.

On the under side o f the bars A are feet B, which fit in between said rims or flanges P and take all the wear ensuing from the reciprocation of said bars. lhe plate P is bolted to the upper side of the transverse beam R, and about both it and the bars A extend the straps c, by which the latter are prevented from being displaced by any shock that would tend to throw the, same from the plate P. The heads of the bolts by which the plate P is secured to the beam It are beneath the arched portions of the bars A, and therefore do not interfere therewith. This arched portion is made just high enough to give easy room between the same and the plate P for the lever D.

The lever D, when performing its work of oppositely reciprocating the bars A when one is moved, tends to press together the contiguous sides of said bars, and thus cause some little friction. To stop this loss of power by friction I extend the pivotal pin E of the 1ever D and give it a friction-roller, e, by which the two bars are kept slightly apart and the desired end accomplished. It is necessary to recess somewhat the bars A to make room for said roller. l

To keep the hooked ends of the rods s from getting out of the channels a, I provide each rod with a horizontally-elongated eye, T. Each of these eyes T terminate in a screwthreaded shank which passes through the beam R, and is vertically adjustable therein by nuts above and below, as in Fig. 2. These eyes are elongated to permit the rods s passing therethrough to change their hooked ends from one hole a to another.

There are other ways of communicating the motion of the reciprocating bars Ato the feedslide besides the means previously described. The connecting-rod I-I might be attached directly to the leverD,and the gearing dispensed with, but the locking device would be somewhat difficult to arrange in a perfect working condition.

What I claim as my invention, and for which I desire Letters Patent, is as follows, to wit:

l. In a chcck-rower, the combination, with a hooked rod or equivalent device adapted to receive an intermittent reciprocating motion, of two bars, and means whereby the longitudinal reciprocation of one shall oppositely affect the other, and adapted to cause the said hooked rod to engage with iirst one and then with the other of the bars, for the purpose set forth.

2. The combination of two bars, means whereby the longitudinal reciprocation of one bar shall oppositely affect the other, and each having a groove whereby a hooked rod in either of said grooves shall, when pulled, en-
