CARL \V. SORENSEN, OF RAOINE, \VISOONSIN, ASSIGNOR OF ONE-HALF TO EMIL C. TECKTONIUS, OF SAME PLACE.

SEED-SOWER.

SPECIFICATION forming part of Letters Patent No. 416,127, dated November 26, 1889.

' Application filed September 8, 1888. Serial No. 284,415. (No model.)

To all whom it nuty concern.-

Be it known that I, CARL W. SoRENsEN, of Racine, in the county'of Racine, and in the State of WVisconsin, have invented certain new and useful Improvements in Seecl-Sowers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to seeds owers, and will be fully described hereinafter.

In the drawings, Figure 1 is a plan View, in section, on line 1 1, Fig. 3, of my invention. Fig. 2 is a section on line 2 2, Fig. 3, showing the distributer in plan. Fig. 3 is a section on line 3 3, Fig. 1. Fig. 4 is a section on line 4 4, Fig. 5. Fig. 5 is an end view of the clutch. Fig. 6 is a section on line 6 6, Fig. 1. Fig. 7 is a detail. Fig. 8 is a section on line 8 8, Fig. 1. Fig. 9 is a section on line 9 9, Fig. 1. Fig. 10 is a detail View showing the manner of securing the shelf which supports the seedsower to the end-board of a wagon.

A is the shelf that projects from the endboard B of a wagon, to which it is secured by brackets a, the vertical portion of each of which is bolted to the endboard, while its horizontal portion projects out under the shelf and is formed with a flange b, that lies against the edge of the shelf and has lugs c, that overlap its edges, thus serving to stren gthon it and prevent it from warping.

The shelf A is apertured at or near its center, and in one side of this aperture is fixed a bearing (Z, having a hollow arm (1, by or through which it is bolted to the table. The outer end of arm cl stands at right angles to its greatest length, and an opening 01 therein leads through the arm to the interior of the bearing to afford a channel for conveying a lubricant to the shaft 0, that has its upper bearing therein, and which carries the feedwheel D and distributor E.

F is a portion of the usual bevel-wheel of constructed, by the sudden starting of the horses when the machine is at a standstill, or by any jerking or unusual strain applied to the wheel or pinion when the device is in motion.

G is a disk that has an upturned flange e on its outer edge, and this disk is adjustably centered to the under side of an annulus H by a series of lugs f on the under side of said annulus, the disk and annulus being loosely held together by clips f, that are screwed to the under side of the lugs f. The lugs f are formed with offsets f which support the body of the annulus out of contact with the shelf A, and the screws g, that secure the annulus to the shelf, pass through its offset portion. The base-ring h of the hopper is secured to the annulus by jaws 7L, bolts 7L2, and thumbnuts h The disk G has an arm 5, that extends out from it toward the wagon, and a boss j on the outer end of this arm rests on a perforated quadrant, upon which it is locked by a pin 70, that is projected loosely through boss j into the perforation that registers with pin it: when the disk is properly set to bring the center opening of disk in proper position with relation to the distributor-arms. On top of arm 't'is formed a guide-lug i, that projects up through a slot in a gage-plate L, which rests on the upper face of arm 2' and extends beneath the annulus H and into the feed-chant ber M, and this plate may be drawn in or out to reduce or increase the area of the dischargeopening m, which leads down through vertical guide-troughs m, that are secured to the under side of the disk.

The upper face of the plate .L is graduated or sealed for adjustment to positions for giving the proper area to the opening for the kind of seed to be sown.

The seed-chamber M is formed by a circular wall M, that is secured to the disk G by bolts that pass through lugs n on its periphery, and a portion of this Wall M forms a gate 9 N, that is hinged at one end to the disk, while its other end fits loosely between upright lugs or pins 0 on the upper face of the disk, so that when the plate L is forced in it will cause the gateto contract the seed-chamber as the outlet is contracted. The guide-troughs are slightly inclined outward and project down between the inner end of the vertical flanges of the distributer-arm and the hub of the distributer, and a segmental plate P is secured to the under side of the shelf in such a position that the lower edge of its vertical portion will just clear the vertical flanges of the distributer. This plate serves as a guard to prevent the seed from being thrown or blown back toward the wagon.

A force-wheel D, of rubber, is fitted on the shaft 0 in the seed-chamber, and a plate S is fastened down on the upper edge of the wall of the seed-chamber, which plate prevents the seed from falling down through the opening m directly from the hopper.

The elasticity of the rubber of which the feed-wheel D is made is sufficient to secure it against turning independently of the shaft 0 under ordinary circumstances; but if a stone or nail or another foreign body should get in the seed-chamber and clog the wheel the shaft will slip in its bearing in the wheel and revolve independently of it; or, if the obstruction is slight, it may suffice to merely bend the elastic fingers of the feed-wheel, and so permit said fingers to yield and clear it.

One member R of the clutch of the drivingshaft R consists of a sleeve, on which the sprocket-wheel T, that drives it, is loosely splined. A11 annular groove T is formed on one end of sleeve R to receive the spanner of lever R while the other end is formed with lugs 1', that project between similar lugs 0" on the member R, that is keyed to the driving-shaft.

The gage-plate L is held in adjustment by a clamp 2' and set-bolt t and the feed to the distributor is regulated to suit the kind of seed to be sown by forcing the plate L in or out, so as to enlarge or contract opening m and seed-chamber, for as the plateL is drawn out it uncovers the opening on, and, drawing gate N with it, enlarges the seed-chamber, and when it is thrust in it produces a contrary effect.

The throw of the seed is regulated by turning arm ito the right or left, and thus carrying the opening-m and guide-troughs to the right orleft, according to the direction of cast desired.

The Win gs E of the distributer, having vertical blades which terminate about on a vertical line with the opening m in the disk G and the lower end of the troughs m, depend nearly to the base-plate of the distributer E and in the circle of travel of the inner ends of the blades, their lower ends being closed by a flange m that guides the seed out to the wings.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a disk having a suitable seed-opening and forming the bottom of the hopper, of a seed-chamber formed by a semicircular wall secured to the bottom of the disk and a gate hinged to said disk, and a sliding gage-plate connected to said gate and adapted at once to contract or enlarge both the seed-opening and the seed-chamber, substantially as described.

2. The combination, with the disk forming the bottom of the hopper and having a seedopening on one side of its center, of a seedchamber arranged on said disk, the usual distributer-shaft, a plate covering the seedchamber over the seed-opening, and a feedwheel carried by the distributor-shaft and adapted to yield when opposed by extraordinary pressure to permit the shaft to revolve independently of it, substantially as described. 3. The combination, with the seed-chamber and its outlet-opening, of an approximately vertical trough extending down from the seedopening and having its lower end closed by a horizontal guiding-flange, and a distributer the blades of which travel in a circle about the lower portion of the trough, substantially as described.

a. The combination, with the sower and supporting-shelf, of a bearing for the distributer-shaft having a hollow arm that extends out to one side of the shelf, substantially as described.

5. The combination, with the disk and seed chamber, of the guide-troughs and distributer and a segmental plate depending from the shelf and overhanging the path of the inner end of the distributer-blades and with the troughs forming a channel from the opening in the shelf to the distributer, substantially as described.

6. In a seed-sower, the combination, with the distributer-shaft and its bevel-pinion, of a driving-shaft and a bevel-wheel carried thereby, a clutch mechanism, and a sprocketwheel splined on one member of said clutch mechanism and adapted to adjust itself there- I 011 to align with the sprocket of the wagonhub, substantially as described.

'7. The combination, with the seed-chamber and its outlet-opening, of a distributor having a vertical shaft and radially-disposed vertical blades'whose inner ends terminate at some distance from said shaft, so as to leave an annular channel around the latter, and an approximately vertical trough extending down from the said seed-opening into said annular channel, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Racine, in the county of Racine and State of Wisconsin, in the presence of two witnesses.
