IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 9,004, dated J nne 8, 1852.

To all whom it may concern:

Be it known that I, JAMES P. Ross, of Lewisburg, in the county of Union and State of Pennsylvania, have invented certain new and useful Improvements in Seeding-Machines; 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 of the usual manner of making, modifying, and using the same.

My improvement consists in the seeding apparatus by which the seed is conveyed in measured quantities from the hopper to the tubes which conduct it into the teeth, and also in the mode of hoisting the teeth, by which a much larger range of motion can be given to the teeth than is practicable where levers are used; also the mode of throwing the seeding apparatus into and out of gear; and, lastly, the measuring-index for measuring the quan- -tity of land seeded.

Myfirstimprovement, the seedin gapparatus, is thus constructed The hopperais fixed upon the usual frame, I), mounted upon wheels, to the front end of which the draft-bars of the teeth 0 are jointed. This seed-hopper a is made with the front slanting down backward from the top to the rear side at the bottom,as clearly shown. The hopper extends from one side of the frame to the other, and has partitions in it dividing it into as many cells as there are openings for the delivery of seed. Onto the back board of the hopper are metal plates d, screwed opposite to each opening through the seed-box, for the delivery of seed. One of these plates is shown detached, Fig. 2. It supports and guides a gate, 6, which rises and falls to open or close the opening 01 in the plate (I. This gate 6 is moved up and down by the eccentric j, which turns to the right or left for that purpose, as will be clearly shown in the detached figures. On the lower end of the gate there is a projection, h, inward for a purpose to be presently explained, and the projection f on the eccentric f serves to point to the index or scale on the plate d, to determine the quantity of grain to be sown to the acre. There is a cupformed piece, t, which fits onto the plate d, the upper part of which is directly under the opening in the hopper. This fits and slides against the plate d, the lower edge of which fits the line i. That part which projects beyond the hopper is divided into two receivers, F, by an indentation in the middle, opposite which there is boss, i rising nearly on a plane with the plate. The cup thus formed is joined by a short piece of iron, k, with the next cup, and so on to the end of the hopper, where they are connected with a short pitman, 70, that slips onto an cecentric wrist, I. When in a state of rest this pitman is drawn onto a part of the wrist which is concentric with the shaft; but when it is to be put in motion it is slipped onto the eccentric wrist, which wrist is connected with a short shaft and bevel-wheel, m, by which it is geared to and turns with the wheel. When the cups are made to vibrate from side to side their action is as follows: They receive a supply of grain from the hopper, and are always full when there is a sufficiency of grain to fill them in the hopper. While the pressure at their exit is always equal, there is a quantity of seed forced out in vibrating one way on to the receiver i Aided by the action of the projection on the lower part of the gate, the return causes the grain to be forced off of the receiver by the stud 0 on plate 01 at the point 133, while at the same time the receiver on the other side is filled and in the same way emptied of its contents, which fall into the tube a and is conducted down through the tooth c to the ground, the boss i preventing the grain from running out direct from the cup. In this arrangement the parts do not approach near enough to break or injure any kind of seed large or small, while the distributing is performed with the greatest accuracy. The teeth 0 are, as before named, attached by their draft bars or beams to the forward end of the frame. To each tooth there is affixed a cord or chain that passes up over a windlass, 19-, upon the frame on which, at the center, there is a bevelwheel, q, that works by means of a pinion on a short crank-shaft, r. The crank is moved by hand to wind the chains onto the windlass p, and thus raise the teeth. On the shaft there is a collar, 8, that catches the end of the crank when the teeth are raised and holds the windlass in position, and it also catches the crank when the teeth are down for the same purpose. On the end of the windlass opposite the pitman 70 there is a small crank-wrist with a connecting-rod, t, attached to the pitman by which it is moved, as above described,

'on the upper side.

on or off of the eccentric I, so that when the teeth are raised the cups do not vibrate and the seeding stops, and when they are lowered the seeding proceeds.

The measuring apparatus consists of a circular box, as, having within it a ratchet-wheel and gearing, which ratchet wheel is worked by the pawl y, that is at its lower end connected with the bar It, connecting the cups, and receives its motion therefrom. Its fulcrum is just at the periphery of the ratchetwheel at z, and at that point there is a holding-pawl, a, that holds the ratchet wheel while the upper end of the pawl works into the teeth of the ratchet (See Fig. 3.) An eccentric, b, moves a second pawl, c, which acts on the second wheel, moving it onenotch for every revolution of the first wheel.

Having thus fully described my improt'ements, what I claim therein as new, and for which I desire to secure Letters Patent, is-

1. The seeding apparatus constructed substantially in the-manner and for the purposes set forth, consisting of the cup 13 and receivers, the plate d, gate 6, and their attachments.

2. The mode of putting the cups into motion and stopping them by shifting the pitman k, as described, onto or from the eccentric l by the Windlass, in the manner set forth.

3. Raising and holding the teeth by the 6H]- ployment of the apparatus for turning and holding the Windlass, consisting of a crank and bevel-wheels, as described, so that one man can easily raise the teeth to any desired height, and to a much greater range than can be done conveniently by levers or similar devices, and attach it in that position by the revolvin g clutch, which meets, when at the proper height, with the crank, which it fastens.
