CORN-PLANTER.

SPECIFICATION formingpart of Letters Patent No. 250,748, dated December 13, 1881. Application filed October .28, 1880. '(No model.)

- the following is a full description, reference being had to the accompanying drawings, in which Figure 1 is a side elevation, with a portion of the frame-work in section Fig. 2, a top or plan view, showing one side of a planter with its seed-box and other devices; Fig. 3, a side elevation showing the lever in position to advance the shaft; Fig. 4, a side elevation showing the lever when it has completed its stroke and advanced the shaft.

This invention relates to that class of cornplanters in which the seed-dropping mechanisni is actuated through the medium of a reciprocating bar which is operated by means of a lever operated from a crank-wheel through the rotation of a shaft, the shaft being given an intermittent revolution through a lever which engages with a wire or cord stretched across the field; and it has for its object the simultaneous stopping of the wheel which operates or drives the intermittentl y-revolvin g shaft when the lever which advances this wheel has completed its'stroke and advanced or rotated the shaft a sufficient distance to operate the reciprocating bar of the seeding devices; and its nature consists in providing a slide or stop arranged to be operated in unison with the movement of the cord-lever, and located so that when advanced its point will be in position to engage with a tooth of the actuating-wheel and stop the movement thereof.

Only the forward or runner portion of a com plete planter is shown in the drawings.

In the drawings, A represents the check- .cord lever; B, the toothed wheel for drivin g the shaft; G, the latch or pawl for engaging and advancing the wheel B; D, the sliding stop; E, the groove in which the stop moves; F, the support for the stop; G, the standard or post supporting the lever, shaft, and other devices; H, a cross-piece forming a guide for the cord-lever; I, the shaft; J, the pulleywheel; K, the crank-wheel L L, thelever for operating the reciprocating bar; M, the recipslide or stop.

The cordlever A, with its slot at, is made in any of the usual forms ofconstruction for such levers. As shown, it is pivoted or mounted loosely on the end of the main shaft I, and its upper end is slotted to receive the cord or wire and be engaged by the knots thereon.

The wheel B is firmly secured to the shaft I by keying or in some other suitable manner, so that when revolved it will communicate motion to the shaft. The periphery of this wheel is provided with teeth or lugs b, one face of each lug being straight or tangential, or nearly so, and the other face being inclined or curved.

The latch or pawl C is of the usual construction, pivoted to the lever A, so that its free end will engage the straight face of the teeth or lugs I), and is held in engagement therewith by means of a spring, 0.

The stop D is located in a suitable groove, E, formed in the side of the support F near its outer end, the support at its other end being secured in a firm manner to the upright or standard G. This stop or slide D is set at an incline, and is so arranged that its inner end, when advanced, will approach the wheel B, so as to be nearly in contact with its periphery, so that the inclined face of the teeth I) will strike against the end of the slide, which acts as a stop to prevent further movement of the wheel until the slide is withdrawn, the end of the slide being beveled, so as to be properly engaged by the face of b. This slide D is connected by a link or rod, d, to the lower end of the lever, one end of the link being pivoted in the lever and the other attached by an eye or in some other suitable manner to the slide or stop, and the length of this rod and its connections with the lever and slide are such that as the lever is advanced by the action of the cord the slide will be advanced in unison, and so IOU that when the stroke of the lever is completed the slide will be advanced to be engaged by the face of the teeth I), which stops the movement of the wheel B simultaneously with the completion of the forward stroke of the lever.

As shown, the spring 0 is secured at one end to the bar or support F, and its other end is attached to the slide D, so that when the stop D is advanced the spring 6 will be contracted, and when the cord-knot passes from the lever A the recoil ot the spring will return the lever B and the slide or stop D to their normal condition, to be again advanced to operate and stop the wheel B. Other devices than the form of spring shown can be used for returning the slide or stop D and lever A.

The parts represented by the letters G H I JK L M NO PQ R maybe of'anyofthe well-known forms of construction for such parts in that class of corn-planters in which the seeding mechanism is operated through a reciprocating bar, an L-lever, a crank-wheel, a pulley, and a revolving shaft, having an intermittent in ovement given thereto by the advance of the cord-lever, and such parts are therefore not specifically described, as they are constructed, arranged, and operated as usual.

By means of the slide or stop D, connected with and operated from the cord-lever, it will be seen that the movement of this slide must correspond with that of. the lever, and that by arranging the slide so that when its forward movement ceases it will be at the proper point to receive the inclined face of the wheel lug or tooth a sure and effective stop is provided for the wheel, which will always act when the lever is operated.

nected with the lever, and adapted to advance toward the toothed wheel in unison with the advance movement of the lever, and to engage the toothed wheel for stopping its rotation simultaneously with the completion of the advance movement of the lever, substantially as described.

3. The combination, with the lever A, operated by the check-rod, the toothed wheel B, and the pawl O, of a movable stop, a link-connection between the stop and the lever, and a retractile spring connected with the stop,

. whereby the latteris moved in unison with the lever to engage the toothed wheel and simultaneously stop the advance movement of the same with the completion of the advance movement of the lever, substantially as described.
