i'lvliao'vraivnatn IN SEED-PLANTERS.

To all whom 'it may concern.- v

Beit known that l, JESS-E Timur, ot' Wilmington, in the conntyot' New Castle and State ot' Delaware, have invented certain new and useful Improvements in Seed-Planters; and I do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known, and ot' the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, in which Figure l' is a section; Fig. 2, plan; Fig. 3, rear elevation. The other figures are detached portions.

My improvements consist in the construction and arrangements ot cert-aiu parts ofthe seed-planter by which its action is rendered more certain, eilicicnt, and convenient than any with which I am acquainted.

The frame is an oblong rectangular ligure, a, supported upon two wheels, the axis b ot' which can be either attached or detached at pleasure, so as to revolve with them or not. Directly above the axis is a hopper, c, for containing the grain to be planted, with holes through the bottom for the grain to descend through. Upon the axis l) are small wheels or short rollers d, asmany in number as is required, depending` upon the size ofthe machine. In the peripheries of these rollers d are holes or recesses, into which the grain is received as it revolves under the opening in the hopper. The depth of each ot these holes iscdetermined by a pin, c, that exactly 'lits it, and can be sunk as tar below the surface as is desirable. Into the shank ot' each;

isters. It is'obvious that large or small holes can be made in the roller, to sow large or small seeds, and with one or the other shut olf at will, as shown in the drawings.

I attach to the front of the hopper, at each opening in the bottom, an iron socket, It, so that it can be raised up or lowered. This socket contains a quantity of bristles, which are firmly secured by the set-screws It. This is shown in an enlarged view, Fig. 5, and is a very important;v arrangement for determining the quantity ot' grain dropped. The bristles, by this contrivance, are easily thrust forward when worn oit', and can be renewed when entirely worn out.

To the front of the grainhopper another hopper, k, is affixed, intended to contain guano or other manure. The bottom ot' this hopper is made close, and the front is hinged at its lower part, so that it can be opened the whole length. The bottom has holesiu it for feeding into rollers l on a shaft, m, geared to the axis Z, on which the wheels are, and turning in an opposite direction. lVithin the hopper there is a pnlverizer, n, composed of an axis having upon it projecting teeth, and above this is a false bottom with openings in it,

through which the teeth ot' the pulverizer pass up into the material above, break any lumps found therein, and bring it down to the lower compartment, when it may be carried by means of the rollers into the same spot as the seed, or scattered ,broadcast by the open door in iront. To the front bar ot' the frame the beams o ot' the teeth 17 are jointed. These extend back in au inclined position, having two cast-iron projections, q, from the beam, one on each side of them, to steady them as they are permitted to rise and fallin working. The teeth are made hollow, and are atiixed to the loeam in a way to be presently described. The seed, &c., drops from the rollers r into a directing-spout, i", below, and thence through the hollow teeth to the furrow.

The tooth is affixed to the bea-m by a pin, so that its point can turn back. From its front projects up a brace, s, and has an eccentric, as shown at FiO. (i, so that by turning it more or less the pitch ot' the tooth can be changed for Aditt'erent work.

To 'prevent injury 'to the tooth in striking a stone various devices have been resorted to,

the most common ot' which is to insert a weak Y greatest force at the point of rest; but when the tooth is drawn back with great force it yields, tipping readily,`and the tooth will then be easily pushed back into place again. The lever extends up above the beam, as clearly shown in Fig. I, and from its frontend a rod, s', extends back'to the extreme end of a spring, t, which is attached by its opposite end to the beam, and thence passes under a pin,s,on the brace,'and extends up nearly at a right angle to the rod, a little crook being made just at the pin, into which it tits. By this fixture the tooth will require considerable force' applied t to it to draw the pin ont of the recess, at'ter which it falls back easily into place.

In ribbing ground, when a great number ot' teeth are required, I insert a short cross-bar, u, into the end ofthe beam, to either end of which I atlix a tooth by a joint, the bar itself being so attached to the beam as to swivel and be set at any angle, as. clearly shown at Fig. 7. A bifurcated spout or conductor leads from the hopper to this apparatus, which can also be swiveled to suit the position of the hollow teeth. Each of the teeth are attachedto a curved handle, w, that stands up behind the seed-hopper, and is made to be drawn up to raise the tooth to which it is attached, a small hook on it holding it in'plaee; or they can all be raised at once by a bar, e, to be presently described. Each of the levers or handles Works forward a slide, 5v, in the bot-tom ofthe hopper to cover the opening opposite when it is raised, and draws -it back as it lowers again, so that when any one or all-the teeth are raised the openin gs thereto from the hopper are closed, and when lowered they are opened, readyto drop the seed.

The bar-c is connected with a lever, y, attached to the frame of the machine, by which it can be raised and lowered. A connectingrod, z, connects this lever with another horizontal one, z', that projects forward, and is attached with the coupling 1, that connect's the axle with the wheel. This lever is made broad, and upon it is a counter t'o measure the quantity of ground seeded. This apparatus is shown in Fig. 3, and consists of clock-work impeiled by a ratchet-wheel acted on by a pawl, 2, that moves up and down by means of its connection with a small crank attached to the end of a horizontal axis, 3, carrying a toothed worm-wheel,4, that works into a worm orendless thread, 5, on the clutch above named. By this it will be seen that by the single movement oflever y or z the seeding parts register, and other operative parts are at once thrown out ot'gar and stopped; or anyone of theteeth can be drawn up at a time, which is very necessary .on pointed land.

The hub of my wheel, which turns loose on the axle, I have cast or formed with a recess in it, as shown in Fig. 9,into which I insert a piece of bacon-fat, that I rind to be the best lnbricator, and the mode of using it to be the most etcient. 0n the bacon I place a set of curved springs, s, tting each other, by which the bacon is pressed down, and as it wears the springs are turned so as to present their curved surfaces opposed. llhe two positions of the springs are shown in Fig. 9.

Having thus fully described my improved machinery for seeding, what I claim therein, and desire to secure by Letters Patent, is-

1. The jointed teeth attached to thebeam, as shown in Fig. 7, in combination with the swiveling bifurcated spout to direct the corn, as above specified, for ribbed seeding.

2. The combination and arrangement of the counter 2 with the clutch, as described, so that the counting shall stop when the seed is not delivered.

3. The fingerregister ft' and its appurtenances, as above described, for regulating the quantity of seed delivered.

4. In combination with the seeding apparatus, the pulverizer for guano, Ste., constructed and arranged as set forth.

JESSE URMY.
