' Application tiled October-26, 1883. (No model.)

.To (ri wfwm, if) 711,04/ concern:l l

`Be it known that I, ANDERsoN WooDwARD, of Cameron, in the county of Warren and State of Illinois, have invented certain new and useful Improvements in Check-Row Corn-Planters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to 4make and use IO it, reference being had to the accompanying drawings, which form part of this specification. My invention relates to an improvement in check-row corn-planters; and it consists, iirst,

in the combination of the shaft which operates I 5 the seed-slides, of suitable arms attached thereto, jointed slides which pass vertically through the seed-box, and a spring-actuated cut-off which-presses against the lower end of the slide; second, inthe pivotedlevers for operating the lever which operates the seed-slides, each lever being provided with fingers which are adapted to open, and a suitable slotted guide through which thengers pass, therslides being widest at their rear ends, as will be more fully described hereinafter. j

The obj et of my Vinvention is to so construct the fingers attached to the operating-levers that they will open and allow the balls or stops upon the rope to pass freely through them, and to so construct the slide that it will be easily operated and always reliable inV operation. j

Figure I represents a plan view of a portion of a machine which embodies myiuvention.

, Fig. 2 is a side elevation of the same, partly in section. Fig. 3 is a detached view of one of the levers.

A represents the frame; B, the seed-box, which is placed thereon. This box is placed 4o directly over. the seed-conductor C, in the usual manner, and has a slot, D, cut through its bottom, so that the corn will fall directly into the conductor instead of being fed into the conductor by means of aslide, as heretofore. Pivoted in the conductor isa cut-off, E, which has its lower end pressed against the side of the conductor by means of a suitable spring, F. The corn drops into the conductor and rests upon the top of the cut-off. The 5o slide G moves vertically through the seed-box and the conductor, and is made in two pieces, which are joined together. To the upper piece is looselyattached anarrn or lever, H, which extends backward from'the operating-shaft I. As this arm has a curved movement, and would cause the slide to have more or less of a curved movement, the slide is made in two parts, as here shown, so that only the upper portion will be affected by the circular movement of the arm. In the rear side of the lower part of 6o the slide is made asuitable cup, which receives the grains of corn, and which holds them until the slide is forced downward by themovement of the arm, when the grains `of corn drop from the cup into the furrow.

The operating-shaft I extends across the front of the machine in the` usual manner, and has attached to each of its ends an operatinglever, J. These levers J are connected to a second set of levers, L, which are pivoted at their rear corners in the same manner, and these levers J L are connected together at their inner ends by means of a pin, N, and a recess, O, or in any other suitable manner, so that they will always move in opposite directions. Loosely attached to the upper ends of these levers are the :fingers P, which Aare always held in line with each other by means of the parallel guides Q, which are` secured to the upper end of each lever. These guides prevent the fingers from moving in a line with the levers J L, but allow the fingers a lateral movement, for the purpose of enabling the balls or stops on the ropes or chains to pass freely between them. These lingers project upward through the slots R in the guides S, the slots being made widest at their rear ends. The narrow or front portion of the slots are just wide Y enough to hold the fingers closely together, so

that the balls or stops upon the rope or wire which is stretched across the field, would not slip through between them. The wide ends of the slots allow the fingers to open outward farv enough to allow the balls or stops to slip freely between them when the levers have been moved far enough to operate the seed-slide. The rope or wire, with its balls or stops, passes through the vertical portion of the guide U and back through the spaces between the lingers. lWhen a ball or stop comes in contact with the lfront roc ICA pair of fingers, the lever J is caused to oscillate the operating-shaft I, as it moves backward, and then when the iingers reach the wide portion of the slots, they are iorced apart by the pressure of the ball or stop until the ball or stop `can slip freely between them. \Vhen this ball or stop7 which has just slipped between the front fingers, strikes the rear ones, it forces the lever L backward, and this lever L, in turning upon its pivot, forces the lever J forward, so that the fingers will be ready to catch the next ball or stop.

Heretofore there hasbcen more or less tro uble in having the balls or stops to slip oil from the levers or iingers at just the proper point wit-hout causing too much friction. In order to do away with this binding of the balls or stops upon the levers, the iingers are here made to open atj ust the proper time, so as to let the balls or stops slip" freely between them without the slightest trouble, Each ball or stop upon the rope or chain operates each seed-slide, so as to cause it to drop. The upper end of the slide in each seed-box will be boxed or covered over, so as to prevent the grains of corn from working through the slot through which the arms or levers on thc operating-shaft pass.

Having thus described my invention, I claiml. In a corn-planter, the combination of the operating-shaft, the arms or levers connected thereto, a vertically-moving slide, a pivoted cut-oii, the spring for forcing the lower end of the cut-oft' against the slide, and the seed-con- 3 5 ductor, which is connected by a slot with the seed-box, substantially as shown.

2. The combination of the operating-shaft,

4. The combination of the guide, provided with slots which are widest at their rear ends, with the operating-levers provided with Iingers, and guides to keep the fingers in a line with each other, the ngers being adapted to open outward, to let the balls or stops pass through when the iingers reach the wide ends of the slots, substantially as spec-ined.

In testimony whereof I afiix my si gnature in presence of two witnesses.

ANDERSON VOODWARD.
