' INIPROVEMENTIN` SEEDING-MACHINES.

. Specification forming part of :Letters Patent No. 173,711, dated February' 15, 1876; `application filed December 3,1875.

To all-whom it-may concern:

Be :it `known that I, `DANIEL STRUNK, of Janesville, in the `county of Rock and State Vof Wisconsin, have in venteda new and usefull Improvement in Seeding-Machines; and I d0 hereby declare that the followin gis a full and'exact description of the same, `reference `receptacles filling as they revolve and discharging at any suitable point of their revolution, the quantity of grain dischargedby the cups being regulated by their capacity by means of an adjustable disk; and its object is j an improved seed dropping mechanism, whereby the desired qtiantity of grain can be positively sown, the capacity of the seed-receptacles conveniently adjusted without changingthe speed of any of the parts, and coarse or 'unclean grain sown Without clogging or grinding.

My invention therein consists principally in dividing the inside of the vertically-revolving cylinder into independent and unconnected spirally-shaped seed-chambers; further, in the combination of the peculiar seed-receptacles and the adjustable-disks; and, further,in various combinations, all as more fully hereinafter explained.

'lo enableothers skilled in the art to make my invention, I now proceed to describe the same in connection with the dra-wings, in which-4 p Figure 1 is a perspective view; Fig. 2, a side elevation, with the seed-cylinder and adjustableA disk removed; Fig. 3, an end elevation of the seed-cylinder and adjustable disk; and Fig. 4 is'an end elevation of the seed-cylinder.

Like letters denote corresponding parts in each figure.

A represents the outer easing, having an opening, a, on its top, forming a continuation y of the main hopper of the machine, and suitable tlanges af, by which it is secured in place. B is a cylinder, situated in the easing A and adapted to revolve therein, being rigidly secured to a shaft, B, which passes entirely through said outer casing, and is revolved by anysuitable means. On the inside of the cylinder B are cast spiral flanges or partitions 10, Which extend at regular intervals the entire ilengthof saidfcylinder, and project inwardly 'froml the shell of the same. D is a disk slightly ksmaller than the internal bore of the cylinder IB, andis provided with diagonal slots, adapted to slide overthe ilanges G,- and pass freely in and `out 'of the cylinder, taking vthe direction of Vtlie langesfbut fitting snugly the `several parts. The disk D is supported upon an arm, E, which is sleeved on the shaft B', and lhas a groove, b, near its end for the reception of a forked lever, adapted to move said arm and disk. This arm is just large enough to fill up the central space between the sides of the internal flanges, and thus separates the inside ofthe cylinder into separate and unconnected chambers F, while, by moving the disk back and forth', the size of these spaces can be regulated at will. VThe cylinder B is closed at one end by a head, G, through which openings G are made, the same in number as the chambers F. H is a rectangular projection on the inside of the outer casing, having a hat, smooth face. rlhe face of this projection is about the same in extent as the distance between two of the flanges C, one end of the cylinder and llanges bearing against such surface in their revolution. I is an opening made in the outer casing at any suitable point, and connects with a part of the open end of the cylinder and with the seed-chambers.

The operation of my device is as follows: The shaft and cylinder being revolved, by any of the well-known devices, in the direction of the arrows, the grain in the opening a, by its 'own gravity and by the weight of the superincumbent grain, ows freely and .naturally into the seed-chambers, and is delivered by them into the opening l in regular quantities. The diskis adjusted to make the seed-chambers of the desired capacity.

In planting all kinds of grain, and especially unclean grain, chad, dirt, and fine seeds are liable to get past the disk, between it and the headof the cylinder, and prevent the disk from being moved to its greatest limit.

To remedy this defect, l provide the head with openings, before described, through which the chaff, dirt, and iine' seeds pass, by the revolution of the cylinder and by the incline of the spiral flanges. The spirally-forined seed-chambers and flanges, besides throwing the dirt through the openings, allow the seed to ll them more perfectly and deliver the saine more easily than if the said flanges Were at right angles to the head of the cylinder. Y

The seed-chambers, by being independent andunconnected, have the advantage of delivering positively the same amount of grain in each. The surface H, by being about the same size as one of the spaces, prevents the backward flow orl leakage of the grain, as each succeeding partition comes near enough to such surface to stop the ow of the grain through to the exit after the preceding par-l -tition has passed by the surface and thc grain Letters Patent, is-

1. In a seeding-machine, a vertically-revolving cylinder, having internal spiral flanges, forming independent and unconnected spiral] yshaped seed-receptacles, substantially as and for the Ypurposes set forth.

2. The combination withvthe vertically-revolving cylinder, having independent and unconnected spirally-shaped seed-receptacles, of

v theadjustable disk, substantially as described and shown.

l3.' The combination, with the cylinder By, of the internal spiral flanges, thev` disk, and the openingsv G( in the head of the cylinder, substantially as described and shown.

4. The combination, with the casing A and cylinder B, ofthe spiral flanges C and surface H, substantially as described and shown.

5. In combination, the casing A, having openings a, and I and surface H, the cylinder B, having internal flanges C and openings Gr', and the adjustable disk D, all substantially as described and shown.

This specification signed and witnessed this 22d day of November, 1875. i DANIEL STRUNK.
