CHECK-ROWER FOR CORN-PLANTERS.
@PECIFICATIQN forming part of Letters Patent No. 321,943, dated July 14, 1885.
Application tiled February 10, 1885.
T0 ctZZ whom, it may concern:
Be it known that l, LORENZO D. BENNER, of Peoria, in the county of Peoria, in the State of Illinois, haveinvented certain new and use ful Improvements in Check-Rowers for Corn- Planters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which- Figure 1 represents a plan view of one end and the center of the check-rower; Fig. 2, a side elevation of the end of the same; Fig. 3, a similar view to that of Fig. 2, but with the swinging arm released; Fig. 4, a view of the central portion of the check-rower; Fig. 5, a cross-section.
The object of this invention is the effecting of improvements in the bifurcated lever, in the throwing-off mechanism, and in the center movement.
My improvement is in the bifurcated lever,
' which is of the kind adapted to be intermittently oscillated by the action of the knotted wire and to swing horizontally, and is for the purpose of enabling the adjustment in position of the pivotal connection to the said lever of the connecting-rod which communicates the motion of said lever to the center movement. To permit this adj ustment the said pivotal connection is made on an arm arranged to be moved longitudinally with respect to the bifurcated lever.
My improvement upon wire-throwing-off mechanisms is of that kind in which the wireholding sheave is mounted upon an angularlypivoted plate, and relates to means whereby a single-flanged pulley or sheave can be used.
My last improvement is upon center movements of that kind in which two rack-bars oppositely reeiprocative by means of an intermeshing pinion have bent channels at each end, in which a hooked rod travels,and engages alternately with first one and then with the other of said rack-bars.
In the drawings, T represents the transverse beam usually secured just above the seedboXes of the corn-planter, and O is the crosshcad, having sheaves S for guiding the knot- (No model.)
ted wire. ployedone at each end of the beam T; but as they are alike, I only show and describe one of them.
L is the bifurcated lever, which is oscillated by the action of the knots of the wire and the retroaction of the spring L said lever being pivoted to thecross-head O at L. The center movement consists of the rack-bars B, pinion N intermeshing with said rack-bars. B we the bent channels in which the bent end of the connecting-rod R travels.
To have the arm A joined adjustably to the lever L, I elongate the former in the direction of the length of said lever forming the elbow A. The contiguous surfaces of said elbow and lever being tongued and grooved, and a clamping-bolt passed through the lever and the slot A in said elbow, the desired adj ustment is readily effected. It will be noticed that when the pivotal point of the arm A is moved nearer the free end of the lever L, said point will be, when the lever is given its quarter-turn by the knotted wire, in line with the pivotal point L of the lever L and the center line of the transverse beam T. By this particular adjustment the center movement is given a somewhat sudden start, but a more gradual termination. By securing the arm A at a point of adjustment opposite to that previously described, the lever L is made to give a more gradual start and a more sudden termination to the stroke of the center move ment. Not only do I secure this advantage in making the arm A movable, but the stroke of said arm is made longer or shorter, according to the place of its pivotal point. In case, also, that the rod B should happen to be made too long or too short to rightly engage with the center-movement bars B, said adjustment of its stroke enables such defect to be overcome.
In my improved throwing-off mechanism. P is the plate, pivoted at I to the cross-head G, and provided with the single-flanged pu1 ley or sheave S. The pivotal axis of this plate I? is inclined, so that when it swings down away from the cross-head C said plate is in the position indicated in Fig. 3. There being no flange at the upper edge of the sheave S,
Two of said cross-heads are em-- a wire placed thereon at once slips off. To retain the wire in place when this plate and sheave are up in position, I provide the centrally-notched lug G, adapted to partially surround the upper or flangeless edge of the sheave S. Said lugG may be formed as an integral part of the cross-head G, or may be a separate piece attached thereto. As shown in Fig. 2, this lug G prevents the knotted wire from escaping from the sheave S so long as said sheave is held in place thereat; but upon the displacement thereof the wire at once slips off.
The plate I? is fastened up by means of the lever Q, pivoted to the cross-head, and having the lip Q arranged to drop the end of said plate when the said lever is swung around in line with the erosshead. O11 pulling said lever in the opposite direction, by a cord running therefrom to the driver or otherwise, the lip Q leaves the plate P and permits it to drop outwardly.
In my center movement the rack-bars Band their intermeshing pinion N are secured upon a lateral face of the transverse beam T, instead of upon the upper side thereof. The shaft N of the pinion N has said shaft rigidly fastened to it at one end, and at the opposite end is formed into a crank-arm, N From this crank extends the pitman 0 to the lever O,'
which operates the seeding device of the planter. The advantage which I gain from this arrangement of my center movement is, that the paths of both the crank-arm N and the lever O are in the same plane, and there is therefore not so much destructive wear upon all the moving parts.
The bottoms of the bent channels B are, as shown in previous patents of lnine, made undulating, the crests being at the sides of the holes B farthest from the pinion N, while at the sides toward said pinion the bottoms are slightly lower than the end of the hook R of the rod R. hen, therefore, the rod R is pushed toward the pinion N, its hook R slides up the sloping bottom of the channels until. it drops into the hole B Pulled in the opposite direction, the hook R rests against the elevated side of the hole B and moves the rack-bar B therewith. Instead of dropping into a hole, B, when the hook R is pushed thereto, said hook is liable to rest upon the narrow neck at the side thereof. To prevent this I have provided the ears E, projecting from the edges of the rack-bars, as shown in Figs. 4 and 5. By means of these projecting ears the said narrow necks are so covered as to prevent said hooks from resting thereon, and the latter are made to drop directly into the holes B when brought thereto.
As shown in Fig. 1, the rack-bars and their intermeshing pinion are secured to alateral face of the transverse beam T, and the pitman-rod O is joined to a crank-arm formed at the end of an axis extending from said pinion; but the way in which I most commonly arrange said parts is to place them upon the upper side of said beam and join the pitman Oto a crank-pin on the face of the pinion, as shown in Fig. 4.. The other end of said pitman is connected to the fced-slide-operating lever O.
\Vhat I claim as my invention, and for which I desire Letters Patent, is as follows, to wit:
1. In combination with the bifurcated lever of a check-rower and the connecting-rod which transmits the strokes of said lever to the center movement, means whereby the pivotal connection of said rod to said lever may be adjusted relative to the lever, for the purposes set forth.

5. The herein-described means for guiding the hooked ends of the rods B into the holes in the bent channels B of the parallel bars, adapted to be oppositely reciprocated, such means consisting-of the ears E, projecting from the contiguous faces of said bars, set forth.
