SPECIFICATION forming part of Letter-s Patent No. 393,667, dated November 27, 1888.
Application filed August 16, 1888. Serial No. 282.851. (No model.)
Ta all whom it may concern:
Be it known that we, CARL MAGNUs SAND- BERG and CHRISTIAN DoNATUs RoMANUs SANDBERG, citizens of the United States, residing at McPherson, in the county of McPherson and State of Kansas, have invented new and useful Improvements in Cultivators, of which the following is a specification.
Ourinvention relatestoimprovementsin culro tivators; and it consists in certain novel features hereinafter described and claimed.
In the accompanying drawings, which fully illustrate our invention, Figure l is a perspective view of our improved cultivator. Fig. 2
is a rear view of the same, and Fig. 3 is a detail view of an extension for the shovel.
Referring to the drawings by letter, A designates the ordinary cranked axle having the usual supporting-wheels, B B.
C designates the forwardly converging beams having their rear ends connected by a cross-bar, D, as shown. The rear ends of the forwardly-converging bars or main beams C are provided with the `hooks E, over which the cultivator-beams F are engaged when the machine is not in use. The cultivator-beams F are secured to the axle by the couplings G, and at their rear ends they are provided with the integral standards H, as shown.
It will be observed that the beams are arranged in pairs, the beams of each pair diverging rearwardly and the inner beam of each pair being somewhat longer than the outer beam. This arrangement brings the inner standard to the rear of the outer standard and causes the shovels or scrapers I, secured thereto, to converge rearwardly and inwardly, as shown. These shovels or scrapers are convex in cross-section, extend entirely across the 4o space between thelower ends of thestandards, and have their opposite ends connected to the standards by means of the lugs J, which project from the rear sides of the scrapers and are bolted to the lower ends of the standards, as
shown. The handles J' are secured to the cultivator beams in the usual or any preferred. manner and project upward and rearward therefrom. In the crossbar D, connecting the rear ends of the main beams,we form a central go Vertical opening, in which is mounted a vertical rod, K, havinga head'orflange, L, at its upper end and provided with an eye or hook,
M, at its lower end. A coiled spring, N, is arranged around the upper portion of the rod K, between the head or flange L and the crossbar D, and serves to keep said rod normally elevated. The lower end of the rod is connected to ,the cultivator-beams by the flexible chains O, which have their upper ends connected to the lower end of the rod and their 63 lower ends secured to the beams. This arrangement of therod, spring, and chainsserves to keep the shovels or scrapers normally elevated, as before stated, so that they will take into the earth but a short distance. When it 65 is desired to cut into the soil to a greater depth, the handles are depressed, so as to lower the shovels, the spring yieldingsufficiently, as will be readily understood, but at the same time exerting an upward pressure thereon to cause 7o the shovels to cut uniformly to the same depth. This arrangement of dcvices also permits the shovels to be spread apart, so as to pass by obstructions, but draws them quickly together again into proper working positions after the obstruction has been passed.
In practice, the cultivator is drawn along the field in the usual manner, the shovels or scrapers passing on opposite sides of the row of corn. The scrapers will then take up the 8o loose dirt between the rows of corn and throw the same around the roots of the plants, leaving the spaces between the rows srnooth and even. The shovels being concave on their front faces the dirt cannot pass rearward over the upper edge of the same, so that the work done by our cultivator is very clean and effective.
In the event that the shovels or scrapers are not long enough to throw the dirt well up 9o around the plants, the supplemental plates z z (shown in Fig. 3) may be secured thereto. These plates are similar in shape and construction to the scrapers and are bolted or otherwise secured thereto at the inner ends thereof.
Our cultivator is very simple and efficient, and its advantages are thought to be obvious.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
1. The co'rnbination of the cultivator-frame comprising the axle and the beams mounted theroon and having their x'exwends eonnected '1 heLI rem` ends', the sempers seeure to the 15 hy a cross-bar, 1)7 the rod K, mountzed verti- 1 Iower ends ofsah'l standards and made convex eally in aoentml openingnsnd crossmrnnd in Vertical section, and the supplemental conhaving a flange, I, 21h its upper end and the Vox plntes seoured to the hmm" ends of said 5 eye M nhitslowerend, the spring eoiled around semper, as specied. I
