erence being had to the accompanying drawings.

My invention relates to corirplanters, and it has for its object to provide improved means for actuating the dropping mechanism.

A further object ofthe invention is to provide acorn-planter with improved means for dropping the corn.

A further object of the invention is to provide improved means for throwing the slideactuating mechanism into and out of gear with the earryingwheels by which said actuating mechanism is operated.

A further object ofthe invention is to provide a planter which shall be simple in its construction, durable in its use, and one that will readily and effectually drop the seed at the required intervals.

With these ends in view the invention consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a corn-planter constructed in accordance with lnyiuvention. Fig. 2 is a plan View of the same. Fig. 8 is a transverse section through the corn-boxes. Fig. et is a transverse section taken through the carryingwheels, and showing the actuating mechanism located on the shaft thereof. Fig. 5 is a detail view of the actuating mechanism located on the carrying-shaft, and Fig. (i is a detail view of the cutoff.

ln the accompanying drawings, in which like letters referto corresponding parts in the several Jiigures, A represents the carryingframe, which consists of two longitudinal beams, B, braced at suitable points by means of cross-beams a, and carrying upon one of these cross-beams c the seat b.

G represents the axle, having carrying wheels C', which are adapted to be engaged by a cross-beam, C2, which slides in recesses in the ends of the beams B, which are covered by means of metal plates a. This brake-beam is operated by means of a rod, at, which passes through an opening in the seat-supporting standard, its end being bent in order that it may e readily operated by pressure of the foot.

Upon the forward ends of the beams B is provided a beam, B', the ends of which are reduced and have bearing in the upper forward ends of the runners B2. rllhese runners B2 are suitably braced at their forward ends by means of a crosssbeam, b, and at their rear upper ends by means of two cross-beams, bi. Secured between these beams bl at their upper ends are uprights b3, which are connected at their lower ends to the shoes B2. The runners are further braced by means of beams b, which are secured to the forward crossbeam of the runners at one end and to the beams Z at their other ends.

Upon the uprights b3 and upon the crossbea-ms bL are provided boxes for containing the corn to be planted, which are provided on their inner sides with an opening, for the passage ofthe corn, and cutoifs, as will be described.

l) represents metal plates or slides, which are adapted to work in the boxes containing the corn to be planted, the said slides having openings which intcrmittingly open and close the said openings of the corn-boxes. These slides are connected at their inner ends by means of a rod, d, and are provided with a notched or recessed portion within the box. The uprights upon which the corn-boxes vare located are made hollow, and communicate with said boxes.

Upon the rear sides of the uprights b3 are provided metal plates d', thc upper ends of which rest within the notched portion of the slides, and their lower ends are adapted to close openings in the uprights b, near the lower ends thereof. lt will thus be seen that as the bar to which the slides are secured is actuated the said slides will move back and forth, and in this manner operate the said plates to open and close the openings in the prights, thus permitting the dropping ofthe corn at the proper intervals.

Upon the outer sides of the seed-boxes are provided what might be called bellerank levers7 d", the center portion of which is hinged to the said seed-boxes and their lower ends secured to the slides. Thenpper ends IOC of these levers d* are bent rearwardly at right inner sides of the wheels, and revolves with angles to the body portion of said levers, and

as the slides are actuated the same cause said levers to rise and descend, the outward movement of the slides causing the levers to rise, and the backward or inward movement of the said slides causing the upper arm of said levers to be lowered. Upon one of these' levers rests a marker, (according to the direction in which the planter is planting,) secured loosely at its rear end upon a plate or bracket secured upon the rear side of the seed-boxes. Itwill thus be seen that as the slides are actuated the marker is caused to intermittently rise and descend to mark the ground for the hills next to be planted.

Secured upon the rear of the beams b2 is a lever or double lever, E, the arms e of which are pivoted at about their center to brackets secured upon the inner sides of the beams B at suitable points thereon. rlhese arms c are connected at their rear ends by means of a cross-rod, by which the runners may be raised from the ground and held in that position while the machine is being transported from place to place.

Just above the axle of the carrying-wheels are provided brackets E', which are provided near their upper ends with openings, in which openings are mounted the reduced portionof a rod or shaft, E2. By this reduced portion shoulders are formed whereby the lateral movement of the said bar or shaft is limited.

The outer ends of this bar or shaft E2 are beveled or cut off diagonally, as shown. At about the center of this bar or shaft E2 is a recessed portion, at which point is provided a headed pin or bolt, upon which is a plate, E3, having a longitudinal slot. This plate E3 is also provided at about its center with a longitudinal slot, which works upon a headed pin or bolt securedb to the under side of one of the bracing-beams a of the beams B, and is hinged at its lower or front end to the bar to which the slides are connected.

It will be seen that by forming the connecting-plate with slots and mounting the same upon headed pins that the movement of the runners in passing over uneven ground is accommodated, and all jerking and strain avoided. The axle C is preferably square, and is journaled in brackets depending from the under sides ofthe beams B. The point at which the axle is j ournaled in the brackets is reduced and made rounding in order to allow of its proper revolution. The axle is also reduced and made rounding at its ends in order to receive the carrying-wheels.

Upon the inner sides of the carrying-wheels are secured, to the hubs thereof, blocks which project upwardly and are secured at their upper ends to one of the spokes. Upon the outer ends of these blocks are pivoted pawls F', which are held in position by means of Springs F2.

G represents a collar or disk, which is mounted on the carrying-axle adjacent to the said axle, or the axle is revolved thereby, the disk being provided with a circumferential series of teeth, which are engaged by the spring-pressed pivoted pawls upon the inner sides of the carrying-wheels.

YAd jacent to the collars or disks G, and mounted within an eccentrically-recessed portion of the shaft C, are pinion-wheels G, which are connected by means of a rod, G, which passes through openings in the side of the depending blocks in which the axle is mounted, and rests in an opening in said axle. It will thus be seen that only a portion of these pinion-wheels are exposed. lnclosing the exposed portion of said pinions and the axle at the point where said pinions are located is a collar, H, provided on its inner side with a series of teeth adapted to engage said pinion wheels, by which means said collars are revolved. These collars H are provided with tappets H, which are beveled or cut off on4 their inner sides to engage the beveled portion of the shaft E2, and operate the said shaft intermittingly, one of the tappets occupyinga position directly below the axle while the other one is engaging the beveled portion of said shaft, from which it will be seen that the said shaft is automatically moved backward and forward to open and close the slides.

rlhe ringG is provided on its inner side with teeth G3, which are engaged by the teeth of a disk rigidly mounted on the shaft adjacent thereto, which aids in holding collar G upon the teeth of the pinion-wheel, and prevent its disengagement therefrom.

rlhe disk Gzis provided with a groove or recess on its peripheral edge, which is adapted to receive a U-shaped arm or a lever, H2, the upper portion or handle of which is pivoted between the arms of a bracket secured upon one of the bracing-beams a of the beams B. By this arrangement it will be seen that when disk G2 is shifted from engagement with the ring or collar G, the said ring or collar will not move the seed-slides, inasmuch as they are not braced laterally, and therefore work loosely, so that in transporting the planter from place to place the actuating mechanism is not operated.

The operation of the above-described machine may be briefly mentioned as follows: The corn is placed in the hoppers or boxes and the marker adjusted as described, so that at each movement of the slides it is raised and lowered to mark the hills. The pivoted IOO IIO

pawls upon the carrying-wheels engage vthe toothed disk adjacent thereto, which imparts motion to the shaft, which shaft turns the pinion-wheels and the disks G2, which in turn operate the collar G, the tappet of said collar striking the beveled shaft which operates the slides.

It will be seen from the above description that by the use of my improved machine the necessity of a check-rower is obviated, and that the mechanism for operating the slides E IOV and thc marker is thoroughly efficient andl loosely mounted on said shaft and provided on its inner side with teeth to engage a corresponding series of teeth on the inner side of the collar, and levers adapted to engage the latter-mentioned disk to throw the same into 2o and out of gear with said collar, substantially as set forth.

In testimony that I claim the foregoing as my own Ihave hereunto affixed my signature in presence of two Witnesses.

GRANT LEEPER.
