Seeding-Machine; and that We, GEO. W. VAN

BRUNT, D. C. VAN BEUNT, and HIRAM BAR- BER, all ot' the same place, assignees of the said VAN BRUNT, do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, making a part of this specitication,in which- Figure 1 isla side elevation of the improved seeding-tnachine with the nigh wheel removed. Fig. 2 is a rear end elevation ofthe saine. Fig. 3 is a plan of the saine with the seed-hopper removed. Fig. 4 is atransverse section ofthe seed-cylinder and cap.

Similar letters ot' reference indicate corresponding parts in the several figures.

This invention relates to that class of seeding-machines in which a series of seed-cylinders is employed, arranged on a revolvingshaft, and cachcylinder provided with radial flanges, or, in other words, with flanges projecting frein its convex surt'ace` and extending parallel to the axis of the cylinder.

The invention consists in combining such a cylinder with a cap or cover provided with a chambered recess on its concave side, concentric with the cylinder, and extending from the front edge ot' the feed-opening inthe ca-'p for ward and downward to the edge of the cap itself, whereby such seed as may chalice to lodge on top of the partitions or anges forining the seed cells or pockets is prevented from being crushed or bruised between the partition and the inner bottom edge of the opening in the caps while the seed-cylinders are in motion.

It also consists in a peculiar construction of scattering device, as hereinafter set forth.

To enable others skilled in the art to fully understand and use the invention, we will proceed to describe its construction and operation.

A represents a rectangular frame, which is mounted on two wheels, B B, and has a. box, C, placed on it extendingits whole width.

Within the box U there is placed ashaft, D, which has a pinion, a, 'dttedvloosely on one end and gearing into a wheel, b, attached concentrically to one of the wheels B. The hub of the pinion a protrudes through the boxon its inner .-ide,and on its inner end is provided with the ratchet-teeth, which engage with corresponding teeth of a sliding sleeve, c, when the seeding device is in gear, said sleeve c being moved longitndinallyon the shaft to throw the seeding device in or out ot' gear by means ot'a lever, d.

0n the shaft D there is secured a series of cylinders. E, which may be described as being cylinders provided with radial tiangesf, the spaces g between which form seed cells or pockets. Each cylinder E has a shell or hollow cylinder, F, tilted on it. These shells or cylinders F are slotted longitudinally to receive the iiangesfot' the cylinders E, the parts ot the shells between the slots fitting snugly in the spaces gbetween the flanges fof the cylinders, as shown in Fig. 4.

The shells or hollow cylinders F are each provided with a flange. h, at their outer ends, and these flanges arelitted to revolve in corresponding grooves in the under side of a cap1 which'is formed in two parts, G- H, fitted together with a tongue and groove. The part G, in which the groove s is formed, is secured to the'box C, `and the part H, on which the tongue t is forined,is fitted to slide longitudinally With the hollow cylinder F, on theshaft D, and is supported in a proper position and guided in its movement by means of its tlanges t' t' and laterally-projecting arms j j, (shown in Figs. 3 and 8,) which latter embrace the two opposite sides of the fixed cap G. The groove s in the cap G is made in it back of aline drawn perpendicularly through the center of the cylinders, and has downwardly-converging sides.

0n the under side of the cap G, in front of the groove s, is a. chainbered recess k, (shown in Fig. 4,) concentric with the axis of the cylinders. This chambered recess is to prevent the possibility of any seed which may lodge on the tops of the radial flanges f of the cylinders from being crushed or bruisedin passing under the cap, and the groove or opening s through thecap, through which the seed passes from the hopper to the seed-cells ot' the cylinders E, the opening through the cap being forward ot' a line drawn perpendicularly through the center of the cylinder, eiectually prevents any tendency ot the seed to run out through the chambered recess. The anges of the hollow cylinders F below the axle D run between two iianges of plates (not seen in the drawings) attached to a slide, I, which is moved or actuated by means of a. lever, J, and by this movement ofthe slidethe series of cyliuders F may be inoveda greater or less distanccon the cylinders E, and the capacity ot' the seed cells or pockets thereby varied, as circumstances may require, an index, I, (shown in Fig. 2,) extending rearwardly from the slide l, indicating on a graduated plate the size ot' the seed-cells, and consequently the quantity of seed the machine is set to sow on a given area of ground.

Directly over the box U there is placed a seed box or hopper, L, the bottoni ot' which is perforated immediately over. the cylinders on shaft D. Inside the hopper stinken cavities or depressions are formed in the bottom ininiediately surrounding the perforations.

To the under side of the box C a series of pendent tubes, M, which may be described as two truncated hollow cones united together at their small ends, are attached to the box O, directly under the cylinders. In the lower part of each tube there is a cone, N, provided atits lower end with a circular Bange, m. The cones N are smaller in diameter than the interior of the tubes M, and a space is consequently left between them for the disch-argent seed. The cones are attached in the tubes by a web of cast-iron, the tube and cone beingcasttogether. (Shown by a horizontal section in Fig. 6.)

The machine being thrown in gear and set in motion, the seed runs through the perforations in the bottom of the hoppers and tlls the seed cells or pockets of the cylinders as they are successively brought under the openings. The quantity of seed to be sown on a given surface or area of ground may bevaried by adjusting the slide I, so that the shells or hollow cylinders F may be adjusted a. greater or less distance apart on the cylinders E, and the seed cells or pockets varied in capacity, as required. The seed drops from the cells into the tubes M and falls n the cones N, and is discharged from the lower ends of the tubes in a" scatteringor broadcast state,the form or shape ot' the tubes, in connection with the cones N and dan ges m, effecting such result.

0 is a shaft, the ends ot' which are fitted in bearings in plates P, attached on each side of the frame, and on this shalt O there is placed loosely a series of drag-bars, Q, in the back ends of which cultivator or barrow teeth o are attached by their standards p, which pass up through the bars and are secured by tapering keys driven in behind them, and are braced by rods. The bars Q are allowed to turn freely on the sh att 0, and are kept a proper distance apart by collars, which are placed on the shaft between the bars. By changing the ends of the shaft() in the diti'erent bearings or holes in the plate P the bars are raised or lowered and the pitch of the teeth accordingly varied, as may be desired. The back end of each dragbar Q, has a pin, q, projecting at right angles from its surface, and these pins pass loosely' through the crossbar R and have heads on their upper ends. The bar R is connected by a cord or chain to an eccentric-lever, T, ful crumed in a standard, U, on the back part of the frame. The pins q are of snftcient length to admit of each bar Q rising and falling to a certain extent independently of the others, and by means of the lever T the whole number of bars may be lifted simultaneously above the surface ot' the ground. The teeth o harrow in the seed and pulverize the soil behind the tubes.

Having thus described the invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The concentric chanibered recess k in the cap G, in combination with a cylinder, E, having radial flanges ff, when arranged to oper-` ate in the manner-and for the purpose set forth.

2. The cones N, havinga horizontal circular flange, m, at their lower ends, in combination with the peculiarly-shaped tubes M, when constructed in the manner specified.
