BERNT M. JOHNSON, OF RACINE, WISCONSIN.

COMBINED SEEDER AND CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 348,399, dated August 31, 1886.

Application filed April 20, 1886. Serial No. 199,485. (No model.)

To @ZZ whom, it mag/concern:

Be it known that I, BERNT M. JOHNSON, of Racine, in the county of Racine, and in the State of Visconsin, have invented certain new and useful Improvements in a Combined Seeder, Cultivator, and Land-Roller; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to broadcast seed-sowers; and it consists in certain peculiarities of construction, as will be fully described hereinafter, with reference to the accompanying drawings, in which- Figure l represents a side elevation of my invention, with the distributer-chamber partly broken away; Fig. 2, a vertical longitudinal section on line y] y, Fig. 3; Fig. 3, a top plan view; Fig. 4, a top plan view of the distributers, Fig. 5, a plan view taken on line x m, Fig. l, and Fig. 6 adetailview of thebreakerbeam.

Referring by letter to the drawings, A represents a rectangular frame adapted to support the several operative elements of my seeder.

J ournaled in bearings a on the under sides of the frame, at its rear end, is a shaft, B, carrying driving-wheels C, and at the front end of said frame is a bracket, D, from which depends a vertical journal, a, for a pivotal guidewheel, E. This bracket also forms a means of attachment for a draft-tongue.

The distributer-chamber F is supported on transverse bars l), that are united to the main frame A by vertical standards c, and extending from the open front (l of this distributerchamber to the front of said main frame is a aringhood, G. The hood G has its dischargeopening e extended from side to side of the main frame, and said opening is so arranged that the seed is cast directly upon the ground in a vertical directionimmediatelyin the path of and under the machine, thereby preventing it from being affected by the wind. The distribnters H are keyed to vertical shafts I, that carry bevel-pinions j', designed to mesh with gear-wheels K, fast on the shaft B, this gearing serving to drive said distributers in the direction indicated by arrows, Fig. 4, so as to insure the best possible cast.

The distributer-shafts I are provided with the usual stirring-pins, g, to agitate the seed in the hoppers I', that are suitably secured to the removable cover-plate K of the distributerchamber F.

The cover-plate K is provided with countersinks l1, having segmental seed-passages f,and pivotally operating in the countersinks are disks or eut-offs L, provided with segmental openings 7c, designed to be brought in and out ofregister with the seed-passages in said countersinks by a suitable lever mechanism.

The lever mechanism for operating the disks or cut-offs L preferably consists of a l- -shaped sliding arm, m, having its rear end slotted to receive screws or pins a, extending up from said disks, and an arm,o,fulcrumed to a lug, p, extended from the front of the cover-plate K. This latter arm is loosely connected to the shank of the one, m, and engages a rack, r, on an outer edge of the cover-plate, so as to thus retain the cut-offs or disk in the position to which they may have been adjusted, said arm being within easy reach of the operator of the machine. By the construction just described the seed-passages i may be either entirely opened er closed, or the degree of opening readily regulated to suit various kinds of seed or the amount thereof desired to be sown.

Fitted in bearings s on the under sides of the frame A, near its front end, and to the `rear of the discharge-opening e of hood G, `are the journal ends of a skeleton beam, M,

and to vertical pins t, arranged at intervals in this beam, are loosely secured a series of angular covering-arms, N, that are hinge-joined one to another throughout the series, as shown at u, Fig. 5. This peculiar arrangement ofthe covering-arms N permits the same to automatically adjust themselves to inequalities in the surface of the ground over which they pass, thereby insuring a perfect covering of the seed. The front edge of the lower portion of each coveringarrn N is provided with teeth 1, that serve to break any clods or lumps of earth that may be in the path of the machine.

Extending rearward from the center of the skeleton beam M is an arm, O, that carries a segment-plate, P. This segment-plate engages the forked end w of an arm, R, that is loosely journaled to the shaft B, said arm having lugs lw', in which are journaled friction-wheels l/, that come in contact with irregular cam-faces IOO c on the inner sides of the gear-wheels K. When the machine is in operation, the camfaces c on the gear-wheel coming against the friction-Wheels or roulettes causes the arm Rto slide back and forth on the shaft B, thereby impartinga vibratory movement to the skeleton beam M through the medium of the segment-plate P and arm O,and thus the arms N, secured thereto, are operated to most effectually insure the complete 'covering of the seed. When the machine is not sowing, or at other tlmes should it be desirable or necessary to elevate the covering-arms N, this operation is readily effected by means of levers S, secured upon the journals of the skeleton beam M and having right-angular arms d', that come under against the main portion of said beam, to parv tially rotate the same in its bearings s.l y

By having two levers-one at each end of the beam M--the covering-arms may be elevated from either side of the machine, and racks T are secured to the hood G, to engage these 1evers and retain them in the position to which they may be thrown in elevating said cover- .ing-arms.

Loosely secured to the main shaft B are angular brackets U, the outer ends of which form bearings for a shaft, V, and this latter shaft carries a series of land-rollers, W, that serve to pack down the earth after the seed has been sown and covered. The brackets U are held apart and braced by a stay-rod, X, held in posltion by nuts e on its screw-threaded ends bearing against the sides of said brackets.

Instead of having two seed-hoppers, I may employ a single seed-box of such dimensions as to cover both cut-offs or disks L, though the two hoppers `Will be found more convenlent in sowing some classes of seed, especially those that require mixing, as such operation can be more thoroughly accomplished in the hood G by the action of the distributers H than by the usual method of mixing in bulk by hand.

My sower is designed to sow any kindV of seed, but is more particularly applicableto the sowing of grass-seed, and by its simplicity of construction and operation will effect a saving in time, labor, and expense over the methods eommonly'employed in this class of work.

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