IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 174,756, dated March 14,1876; application filed August 14, 1875.

To all whom it may concern:

Be it known that I, ABNER S. BAKER, of Kalamazoo, in the county of Kalamazoo and in the State of Michigan, have invented certain new and useful Improvements in Seed- Planters and Cultivators and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

This invention relates to an improved broadcast seeder and cultivator, or gang-plow, combined; and it consists in a improved combination of devices for raising the rhomboidal frame or truck, for the purpose of throwing the beveled wheels out of gear, consisting of two compound levers working in standards attached to opposite sides of the frame, and provided with devices for fastening the same in any desired position, said levers being connected with vertical standards to which the wheels are journaled, and which slide in ways formed upon standards or plates attached to the machine on opposite sides, as more fully hereinafter described.

In the drawings, Figure 1 represents a top view of my improved apparatus. Fig. 2 represents a perspective view of the same. Fig. 3 represents a section through the line or y of Fig. 1. Fig. 4 detached views of the right and left plows; Fig. 5, a detached view of one of the compound levers, and Fig. 6 a detached view of the short and main tongues and the adjustable caster.

The letter A represents a strong frame or truck constructed in the form of a rhomboid or oblique-angled parallelogram, and B the Wheels upon which it is mounted. The said wheels are journaled on short journals on the lower ends of the vertical standards 0 U, which are flanged on each side, and are held in ways d d in the standards or plates D D, which are secured to opposite sides of the frame A, and in which said standards 0 O are adapted to move vertically. E E represent two slotted vertical standards mounted on the top of the frame A, on opposite sides thereof, and F F two compound levers passing through the slots and adapted to work therein. Said with, its front edge.

compound levers consist each of two levers, f and f. The lever f is slotted longitudinally at its center, and one end attached to the slotted head of the standard 0, theother end being pivoted to the lever f between its fulcrum or point of attachment g and its handle. Each standard, O has formed on one side a toothed segment, G, to the side of which the handle of the lever f works, said lever being provided'with a'hand pawl, H, which engages the teeth of the segment, but which can be sents the seed-box extending across the front of theframe, directly behind, and parallel Said box is of a trian gular shape, the apex downward, an opening being left its entire length at the bottom, in which there is 'located a recessed shaft or roller, 1, which is capable of a rotary movement, and forces the seed from the box to the distributing-board K below. The said boxI is provided with a series of equidistant partitions, i, and a gage-plate, L, on the inside, secured to one of the sides by means of setscrews 1 passing through 7 slots therein, by which it is rendered adj nstable to regulate or gage the seeds dropped from the box. Said roller or shaft has secured to one end a pulley, M, which is connected by a belt, chain, or band, with a similar pulley, N, mounted on a short shaft, 0, journaled in an adjustable hanger, P, attached to the frame A. other end of said shaft'is mounted with a beveled gear-wheel, Q, which meshes with a larger beveled gear-wheel, R, secured to the wheel B of the machine. This gearing serves to transmit the power from the wheels of the and force the seeds from the seed-box.

under, and parallel with, the seed-box, inclin- The 1 from side to side of the machine from one acute angle to the other thereof, all being turned in the same direction, as illustrated, when the machine is employed as a seeder for sowing-broadcast. For cultivating corn, however, I provide two interchangeable shares turning in. opposite directions, as indicated by the letter A Fig. 4, which are attached and used as hereinafter explained. The letter B represents a short tongue attached to the front of the frame A. To one side of said tongue is attached, by means of a screw-bolt b, a slotted standard, to which is swiveled a caster, C. By this means the tongue and frame can be elevated or lowered at will to regulate the depth of the plows, as will be evident. To the front end of the short tongue is also secured a depending yoke or shackle, D, through which the main tongue E sets, being hinged or pivoted at its rear end to the short tongue at F. Said yoke or shackle is provided with apertures 01 on opposite sides, and the tongue with a similar aperture, through which a pin may be inserted for securing the tongue F rigidly and adjusting the same, or it may be left free as may be desired.

In employing the apparatus for corn I make use of the reverse shares A Fig. 4. I detach the seed-box, or, disconnect the gearing by which the seeder-is driven, and then take out the middle-share leg, leaving three shares or teeth each Sl(IG )f LhQIOV of corn, and by means of the reverse teeth can throw the soil to or from the rows at pleasure.

When the corn is young, in which case it is necessary to throw the soil from the rows, I take 011' the right-hand share or tooth from the middle leg of the left-hand side of the frame, and the right-hand tooth or share from the righthand side of the same, and substitute in their places the left-hand or reverse teeth. After the plant has grown sufliciently to stand the soil necessary to form the hill, I take the two left-hand teeth, and place themone on the left-hand leg on the left-hand side of the frame, and the other on the middle leg of the right-hand side of the frame, in which position they will turn all weeds and grass into the hill. For summer fallow the machine is employed, as first described and illustrated, with the exception of the seeding attachment.

Having fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-- The combination, substantially as described, of the compound levers F ff working on standards E attached to frame A, and the standards G working in plates or standards D, and carrying the'wheels B, on which the truck is supported, for the purposes set forth. I

In testimony that I claim the foregoing I have hereunto set my hand this 27th day of April, 1875.
