Description
lutd what i WILLIAM A. ESTES, OF SOUTH CHINA, MAI-NE.
Letters Patent No. 94,482, dated September 7, 1869.
I'MPRovEMENT 1N REvoLvING cUL'HvAToRs,
The Schedule referred to in these Letters Patent and making part:l of the same.
To all whom 'it may concern:
Bc it known that I, WILLIAM A. ESTES, of South China, in the State of Maine, have invented a' new and useful Improvement in Revolving Gultivators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and letters of reference marked thereon, makingr a part of this specification, in which- Figure 1 is a plan view.
This invent-ion consists of a circular cultivator, divided by cross-beams, into four segments, within each of which is placed a smaller cultivator, the larger one being pivoted upon a draw-bar, and the smaller ones being pivoted upon an annular plate, so that all the. cultivators may revolve as they are drawn along, and the smaller ones be protected by the larger.
To enable those skilled in the art to make and use my invention, I now proceed to describe its construction and operation.
Similar letters in the drawings refer to like parts.
In constructing my cultivator, I employ two wooden beams, a a, of equal length, which I firmly fasten together at their centres, at right angles to each other, making a cross, the four extremities of which are connected by a fiat metallic ring, b, on the upper ,side of the beams.
The space within the ring is divided by the beams into.four equal segments, within each of which is placed a srnaller-cultivator, (l, constructed similarly to the large one just described.
Said cultivators are pivoted at. their centres to an annular plate, c, concentric with the ring b.
At the point where the beams afiutersect, a drawbar, d', is pivot-ed, by means of which the whole apparatus is drawn along.
Teeth are placed at the points x, near the ends of the beams a, and at the points ve, near the ends of the beams of the smaller cnltivators. As the machine advances, all the' circular frames revolve, and the teeth thoroughly pulverize the ground. The smaller cultivators are all well protected by the beams a and ring b.
What I claim as new, and desire to secure by Letters Patent, is-
The larger cultivator herein described, in combination with the smaller cultivators, placed entirely wit-hin the larger one, all arranged substantially as described.
WM. A. ESTES.
