GEORGE ESTERLY, OF WHITEWATER, WISGON SIN, ASSIGNOB OF ONE-HALF INTEREST TO BENJAMIN KUHNS.

IMPROVEMENT IN BROADCAST SEEDER AND OULTIVATORL Specification forming part of Letters Patent No. 79,332, dated June 30, 1868; Reissue No. 8,385, dated August 20, 187 8; application filed J unc 20, 1878.

1'0 alt whom it may concern Be it known that I, GEORGE ESTERLY, of Whitewater, in the county of Walworth and State of Wisconsin, have invented a new and Improved Broadcast Seeder and Cultivator; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a top view, in detail, of one side of the improved machine, showing the bottom of the seedcup closed by the cylinder of the discharging device. Fig. 2 is a longitudinal. section taken in the vertical plane indicated by line y in Fig. -1. Fig. 3 is averticalvsection taken through the machine, as indicated by the course of line a: a; in Fig. 2. Figs. 4, 5, and 6 represent the construction of the seed-cup and discharging device. Fig. 7 is aperspective view of one of the hoes and its fastenlngs.

Similar letters of reference indicate correspondin g parts in the several figures.

This invention relates to certain novel improvements in seeding-machines.

My invention consists, first, in a secondary hopper or seed-cup havingadistributing-wheel,

supported by bea-ringswithin the seed-cup, in combination with devices for shifting .said wheel laterally for regulating the sowing ca- I V pacity of the said seed-cup, as will be hereinafter more particularly described; second, in a secondary hopper or seed-cup supporting a seed-wheel turning, on bearings in said 'hopper, and having a laterally -inoving cut off to widen or narrow the carrying-surfaces of the distributing-wheel; third, in a secondary hopper or seed-cup, in combination with a rotating laterally-adj ustable distributing-wheel arranged within said hopper or cup,'and a rotary. shaft connected with and passing through the center of said wheel, whereby rotarymotion may be communicated to said distributin g wheel by means. of intermediate gear'connecting said shaft with the axle of the travel:

in-g wheels ofa seeding-machine; fourth, in

- the combination, 'with arseed-cup, of a loose ring having arim-bearing therein, and pro-, vided with centrally and laterally projecting teeth, and a distributin g-wh eel having its bearing within said ring, and providedwith radial projections adapted to slide between the teeth of said ring, whereby the distributin g-wheel is permitted to move laterally, and is guided while so moving, ticularly explained; fifth, in combination with a laterally-moving distributing-wheel and cylindrical cut-011a circular flange having lateral segmental projections and slots formed in it, which fit the teeth and cells of the distributing-wheel, said flange formin g a revolving bearing for the wheel in the seedcup, as will be fully described and explained hereinafter; sixth, the combination, with a seed-cup or hopper, of a distributing-wheel and a rotary cut-ofl', each having a bearing within saidcup or hopper, and both adapted for lateral adjustment therein; seventh, in a novel construction of conical scatterers for seed-discharging tubes, said conical scatterers being provided with eireular ribs or corrugations upon their surfaces, whereby the flow of seed is interrupted and deflected laterally, so that the seed are scattered over a great extent of ground in all directions.

It also consists in certain details oi construction and specific combinations of devices, which will be hereinafter particularly described, and

pointed out in the claims.

In the accompanying drawings I have represented only those parts of a complete working machine which are necessary to illustrate the construction and operation of my invention, and have shown one distributer attached to the driving-shaft.

-' In a practical working machine of this kind I employ about twelve drag-bars and hoes and five seed-distributers. I also employ a lifting-bar for the drag-bar, with devices whereby the driver, sitting upon the machine, can raise or depress all the dragbars simultaneously, and retain them at any desired height.

I also employa seed-hoppcrover the seed-distributers, upon which the driver having controlof the machine c'an'sit.

These several parts do not constitute any part of my improvement and'invention, and may be constructed and applied in any suitable or well known-manner. Q

. The draft-frame consists of longitudinal beams A and transverse beams A A, secured together and braced in any suitable manner, so as to form a strong frame for receivin g and supporting the seed distributing and covering machinery. I have represented only so much of this draft-frame as is necessary to illus-j .trate one of the seed-distributers and the hoes belonging thereto.

- B represents one-of which is keyed fast turn this axle when the machine is moved the transporting-wheels,

along; and N represents a long spur-wheel, which is applied loosely upon the axle 0. but

at all times, by means of the key-tenon n (shown in Fig. 3,) and this drum is moved up to and from the hub n of wheel N by P, one end of which embraces the drum, and has steel pins fitted into an annular groove made therein, as shown. 7

Lever P is pivoted to the bottom side of the rear beam, A, of the draft-frame, and extends out in rear thereof, as shown in Fig. 1. Beneath the draftfl-ame,and firmly bolted thereto, is a metal frame, L, which is constructed with bearing or journal boxes for the and on each side, outside of the draft frame, is a casting, E, which is bolted rigidly in place and affords a pivoted attachment for a seed-hopper, (not shown in the drawings;) also, the axle O, and also a rear bearing for supwhich the drag-bars are The rear BXtGIISlOIB C, is set outward, from the main portion of its plate E, as shown in Fig. 1, for the purpose of allowing the dragbar D to be brought as near the side of the wheel 3 as possible without touching this wheel. Between'the e lateral ofl'setbearings 0 there may be inter; as at E, for strengthening and stifl'eningthe rod-BK v The drag-bars vD are pivoted at their front ends to this red Dfland properly spaced by means of cylindrical shown in Fig. 1. These drag-bar's. have free vertical motions, and carry hoes D heart-heir rear ends for stirring the soil. and covering in f the seed. I v y I will describe the manner of constructing and applying'thehoes after I have described invented by me for. discharging theseed. g

The teeth of the long spur-wheel- N above described engage with the teeth of a pinionwheel,.K which is "keyed fast up on a shaft, K, that extends transversely acrossthe draftframe, andhas its bearings uponv the upper side thereof, as shown in Figs. 1 and 3. f

On one side of the wheel K is an annularlyare fitted loosely, which studs are upon the upon its axle C, so as to means;

This the surface of therotarydistributer J and cylindrical cut-ofi' J, and sweep back the seed, so as to prevent it from escaping too rapidly. The seed-cup or distributeris preferably made of two horizontal sections, they form a bearing for v the revolving seedwheel and shaft carrying the wheel. The seedcup is also constructediwith an enlarged free extendingdown inrear of the distributer into the open space which is below the-said distributer. This open space is arranged directly over the seed is guided therein by the trough-shaped extension flof-hearingG. The front as well astheside wings. of the cupand its bearing are circulanior receiving thedistributer, and fittingfsnugly against it, sees. to prevent any the passagefl, as described. I 4

Onone side of thebearingGacircnlarchannel is formed by the lip o, through the bottom of which is an; opening, fitheope'ning through the main portion of the :bottom of this bearing. (Shown in Figs. 3 and 5.) In this chaunel is-a circular flauge,S,

it, and an opening through it corresponding in shape to the tootheddistributer-J, so as to allow the teeth thereof to move longitudinally through it when shaft K is adjusted by means S areshaped-so as to fit into. the tween the teethfof the distributer, and to abut snuglyagainst the ends of the cylindrical cutofl'J" when this latter is moved freely beneath the throat dot the seed-cup, as shown in Figs. 3-and5.

The seed is received from the seed-box or main hopper into a flaring chamber or throat.

The "I seed-cup may be also constructed with a hollow elevation, d extending upon one side of itsa packing, f, of india-rubber or other suitable packing is designed to press upon- F and G. Together seed-tube H, and the seed escaping from the throatd except through lacommunieating with having-segmental projections S on one-end ofof the lever K. The segments Son theflange p c rate and fitted together, as shown in the drawin gs, and secured across the space between the two parallel beams A A by means of screws, or in any other suitable manner. Within the circular space which is formed by the seed-cup is fitted the device for regu' lating the discharge of the seed from the throat (I and for cutting off the discharge completely. This device consists of the toothed wheel J and a plane-faced cylindrical portion, J. The toothed portion affords the seed-cells, for discharging seed from the throat in greater or less quantities, according as more or less of them are exposed beneath this throat, and the cylindrical portion J serves as a means for closin g the said throat. This distributer and cutoff is bored out somewhat larger than the di ameter of the shaft K, and when applied upon this shaft it is attached to it by a cross-pin, t, (shown in Fig. 3,) which passes loosely through the shaft and tightly through the distributer and cut-ofl'. Beneath the openings through the bottom of the seed-cup is the tapering seedt-ube H, which is secured to the beams A A, and extended down in front of the axle O a proper distance. This tube H has a cone scatterer, I, suspended beneath its discharge end by the pendants g, upon which cone the seed fall, and are spread and scattered-over the ground in every direction. To effect this scattering of the seed more perfectly, I form annular ribs g upon the surface of said cone, as shown in Figs. 2 and 3, which will interrupt the streams of seed, and scatter them uniformly and over a large surface of ground.

Each one of the hoes D" is of a lozenge shape, and is secured to a standard, D, which passes through an oblong slot through the drag-bar D. The standardD is pivoted to the drag-bar by a transverse ,bolt, a, and constructed of the form substantially as sh own in Figs. 2 and 7 with its front portion, a, curved in the form of a segment, and provided with a clamp, which serves as a stop to resist all ordinary backward pressure against the hoe.

This clamp or stop consists of a forked casting, 1), which partly embraces the portion a on top of the drag-bar D, and which is constructed with an eye-piece, 1), upon it, through which the screw-threaded end of, a hooked bolt, 1), passes. The hook of this bolt embraces the curved portion a of the standard D, and the straight portion receives upon it a nut, by means of which the device can be clamped firmly to the standard. By loosening this nut the standard can be adjusted abdve its pivot a, and set to run at any desired pitch or inclination. Should the hoe strike an obstructionin its path which mightbr'eak or derange the machine, the clamp-stop will allow the standard D to slip backward, and thereby pass unimpaired'over such obstruction.
