IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 9,882, dated July 26, 1853.

To all whom it may concern:

Be it known that I, JACOB H. OAROIHERS, ofDavidsburg, in the county of Blair and State ofPennsylvania, have invented a new and useful Machine for Planting Corn; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, forming part of this specification, in which the several parts are represented as follows:

Figure] is a plan of the machine. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical section upon the line w 00 of Fig.1. Fig. at is a front elevation of the tooth, showing the manner of securing the point.

Similar letters in the several figures refer to the same part of the machine.

The nature of my invention consists in connecting the hoppers and planting apparatus with two arms movable about the rear bar of the machine, so that the planter can be operated upon uneven .ground, and be made to pass readily over obstructions without interfering in any manner with the regularity of its operation; and, also,in theconstructionofthe drilltubes with movablepoints, so as to be readily replaced when from long use they become too worn for service.

In the drawings, A is the frame, movable upon the wheels B B O, which are so constructed as to be adjustable vertically for regulating the depth of the teeth D.

The planting apparatus consists of the shaft E, having at each extremity a roller, F, and in the middle the wheel G, which produces a rota ry motion of the shaft by the forward motion of the machine. This shaft E is connected with the arms H by straps, which surround the shaft, and has a motion about the rear bar, I, by

reason of the hinges b b, which attach the arms II to the rear bar. The hoppers K are also fastened to the arms H, so that they are influenced by the motion of the shaft E about the bar I, as will be hereinafter more fully explained. The rollers F are partially surrounded by the straps c, which proceed from the bottoms of the hoppers and fit closely to the surfaces of the rollers. The lower portions of these rollers, with their coverings 0, rest in therecesses d of the frame A, which open at the bottom into the hollow teeth D. The teeth are constructed as seen in the drawings the permanent portion having in its face the openings ff, the large one to admit the rivet g on the movable point, after which the necks of the rivets g g are pressed into the slots f, thus holding the point perfectly secure.

In the bottom of each hopper is the slot h, one-half of which is covered by the slide t,- and -on the face of each roller are four recesses,

placed at the distance of ninety degrees from each other, two constructed to pass under the slide *5 and the others under the open portion of the sloth at each revolution of the roller. These recesses are capable ofholding the three grains of corn necessary for the hill, and when the slide 2' is in position the recesses passing under it are inoperative, so that but two hills of grain are planted at each revolution of the wheel G.

The operation of my machine is as follows: The wheels B B C are first regulated to the depth the teeth Dare to sink and the team attached at P. The teeth D, which are the proper distance apart, make the furrows as the machine moves forward, and the rotary motion of the wheel G revolves the rollers 1* within the casing c, causing the recesses in the face of the roller, as they come under the slot h, to receive three grains ofcorn, which it carries round and drops through the drill-tube into the furrow. The wheel G is of the proper diameter for dropping the corn so that the hills shall be three feet apart. Should it be required to form the hills so as to be separated but half that distance, we remove the slides 1 allowing the opposite recesses to operate so as to produce the desired effect. It' in the progress of the machine an obstruction should be met with or the ground be uneven and irregular, the wheel G will accommodateitself to the surface, raising the shaft E and hoppers K, at the same time continuing the revolution of the rollers F, so that the regular distribution of the grain shall not be impeded. Should it be desired to suspend the planting at any time, the lever m is moved to the right, operating the levers a and a and driving their pointed armsp andp into the holes 1" in the sides of the wheel G, so that it becomes locked, the shaft E ceases to revolve, and the rollers F no longeroperate. The brake is removed by moving the lever m in the opposite direction, and the planting proceeds as above described.

The principal advantage of my machine consists in the connecting of the whole planting apparatus to the swinging arms H, so that the operation of the machine can never be interrupted by the uneven nature of the ground, thus causing the rollers F to revolve and deposit the proper amount of grain in the exact position required, without regard to the obstructions met with in the progress of the machine.

lhe ease with which the planting apparatus is thrown out of gear is also deserving of notice,it being accomplished by the simple movement of a lever-within the immediate reach of the driver.

The addition to the ordinary drill-tooth of the movable point is, Iconsider, an important feature in my machine. The two slots into which the necks of the rivets g g are pushed will always hold the point firm, for the reason that in use the tendency of the tooth-point will always be upward, and consequently the points will be self-tightening.

What I claim as my invention, and desire to secure by Letters Patent, is-

The method of stopping the seeding apparatus by grapplingthe periphery of the drivingwheel in the manner herein described.

In testimony whereoflhave hereunto signed my name before two subscribing witnesses.

JACOB H. OAROTHERS.
