CULTtVATlNG SEED-PLANTER.

Specification forming part of Letters Patent No. 7, 16? dated March 12, 1850.

To all whom it may concern:

Be it known that we, WILLIAM FLORY and GEORGEA. GROVE, ot' Ohambersburg, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Seed-Drills; and we do hereby declare that the following is a full,clear, and exact description-of our improved seed-drill, reference beinghad tothe accompanyingdrawings,which form part of this specification, and in which Figure 1 represents a viewin perspective of the machine, and Fig. 2 a vertical longitudinal section of the same.

Our improved seed-drill is so constructed that the deposit of seed is regulated bya register, above which the seed is continually agitated, thus insuring a uniform discharge. The several cultivator-teeth, also, which form the furrows, and which are secured to tubular shanks, are arranged in such manner that either one or all can be raised from the ground and secured in their raised position, while at the same time the raising of any one tooth stops thedischargeof seed throughitstubular shank.

The most important improvement invented by us is a device for crushing and crumbling clods, arranged to precede the cultivator-teeth, thus smoothing the ground and reducing it to an even surface before the seed is deposited.

In the drawings,A is the frame of our drill, composed of suitable len gth-bars and cross-bars properly framed together and hung from the axle or shaft B of two wheels, O 0, one being on each side of the frame. One, 0, of these wheels is loose upon the shaft. The other, C, is secured to it, sothat the shaft is forced to turn with the wheel in its progressive motion. The shaft is a cylinder perforated at suitable intervals with rings of cup-shaped cavities a a, which discharge the seed. A hopper, D, is supported on the frame of the drill immediately above the cylindrical shaft B, and a series of openings equal in number with the ringsof cupshaped cavities are made through its bottom (1. Each opening is closed with aplate, b, in which a hole is made large enough to allow of the free passage of the seed when it is to be deposited in the largest quantity. Immediately below these plates a sliding register, 0, is placed. This extends the whole length of the bottom of the hopper, and is pierced with aset of holes corresponding in number and position with the holes in the plates b. Itis operated by ahandlever, e, in such manner that it can be moved along the bottom of the hopper, so as to diminish or close entirely the holes in the plates 1), or to leave them unobstructed at will, and thus regulate the quantity ofseed discharged. Immediate] y above each plate is a separate register,f, sliding at right angles to the large register beneath the plates. 'lhis register is prolonged and passed through the back of the hopper-frame,wliereitis connected with ahook, g, depending from theinner or hinged extremity of a hand-lever employed to raise the tooth E for making the furrows. These teeth correspond in number and position with the openings in the bottom of the hopper. Each is secured to the lower extremity of a tubular shank, h, through which the seed from the cylindrical shaft 'B is conducted by a flexible chute, t, and pipe t",and dropped into the fur rows made by the teeth. Each shank is attached to a compound beam,L, whichishinged at its front extremity to one of the cross-bars of the drill-frame. The beam is composed of two members, 1" r, the length of the upper, 1', being unalterable, while the lower, 1", is pierced at its front extremity with a series of pivotholes, 8, any one of which may be used to connect this member of the beam with the crossbar, and thus by varying its effective length vary correspondingly the inclination of the shank of the cultivator-tooth. Each shank is connected by a chain, It, with its respective hand-lever j, by raising which the tooth is raised, while at the same time the book 9, depending from its hinged extremity, draws the registerf over the hole in the plateb and stops the discharge of seed. When any one handlever is raised it may, it necessary, be secured in that position by a catch, l, on the back of the hopper. The hinder extremities of all the hand-levers, when down, rest upon a cross-bar, H, extending from one side of the drill to the other, and attached at each extremity to the binder extremity of an arm, m, hinged at its front end to the frame, so that by raising this cross-bar the whole series of hand-levers resting on it are also raised. The cross-bar, with the hand-levers, may then, if necessary, be secured in its raised position by aspring-catch, l, projecting from the back of the hopper.

The device for preparing the surface of the ground previous-to the deposit of seed is composed of a roller followed by a harrow which precedethecultivator-teeth. TherollerIturns upon journals received in hearings in a frame, K, which is connected with the front part of the drill-frame by the bars at, whose upper or front extremities are hinged to the drill-frame to allow the roller to rise and fall.

The harrow J is formed of a heavy bar, 0, furnished with teeth which project from its lower face. This bar is connected with the roller-frame by two rods, 1), which are hinged to the frame. The harrow is connected by a chain, It, with a hand-lever,j, by which it, together with the roller, canbe lifted from the surface of the ground. This hand-lever is hinged at its front end to one of the cross-bars ot'thedrill-frame, and its hinder extremity rests upon the cross-bar H, by which it can heraised at the same time with the cultivator-teeth. A separate catch, Z, is also provided for it, by which it can be secured in its raised position independently of the other levers. A pole or shalts are attached to the front of the drill, to-

which the team is hitched.

When the machine isin use the several members of it occupy the positionsin which theyare represented in Fig. 2, the roller and harrow preceding the cultivator-teeth and preparing the ground. When any of the cultivator-teeth become cloggedit can be raised from the'surface by its appropriate hand-lever, while, as

fore the teeth form the furrows.

before stated, the discharge of seed is stopped by the same operation. The teeth and the roller, with its harrow, may also-one or all-- be raised to pass any obstruction which would otherwise injure them.

In order that the seed should be evenly deposited it is necessary that the clods on the surface of the ground should be crushed or crumbled and the surface smoothed evenly be- Thisis effected by the rollerandits harrow which precede the teeth, as herein set forth. This pulverization of the soil has the further advantage of causing it to fall back again into the furrows immediately after the passage of the cultivator-teeth, thus insuring the uniform coveringof the seed.

What we claim as our invention, and desire to secure by Letters Patent, is-

The combination of the roller and the harrow for crushing and pulverizing the soil with the cultivator-teeth for forming the furrows and depositing the seed, the roller preceding the harrow, and both preceding the cultivatorteeth, as herein set forth.

In testimony whereof we have hereunto signed our names.
