GEORGE K. JACKSON, OF 'REECE, KANSAS, ASSIGNOR OF ONE-HALF TO CHARLES H. STANARD, OF SAME PLACE.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 498,656, dated May 30, 1893. Application filed January 26, 1893. Serial No. 459,801. (No model.)

To all whom it may concern:

Be it known that I, GEORGE K. J ACKSON, a citizen of the United States, residing at Reece, in the countyof Greenwood and State of Kansas, have invented a new and useful Cultivator, of which the following is a specification.

My invention relates to improvements in cultivators of that class adapted especially for cultivating listed corn; and the objectsin view are to provide a machine of great simplicity, strength, and durability, adapted to run lightly over the listed-corn and to effectually cast upon the same the soil in predeter:

mined quantities, and to efiectually destroy all undergrowth and weeds that have sprung up at the sides of the corn-row.

Various other objects and advantages of the invention will appear in'the following description and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings: Figure 1 is a perspective view of a cultivator constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. 4is a detail of one of the stub-axles.

Like numerals of reference indicate like parts in all the figures of the drawings.

The machine comprises a pair of opposite steel runners 1, whose front and rear ends.

are upturned, as shown, the rear endsbeing provided with horizontal extensions 2. The

front portions of the runners are folded upon themselves to form eyes 3 and are continued rearwardly to overlap the rear extensions 2, thus producing upper side-bars 4, which at. the beginning of said extensions are given a half-twist, so as to lie flat upon the same. It will thus be seen that the runners may, if desired, be formed each of a single piece or strip of steel. An arch of inverted U-shape and designated as 5, has its lower ends laterally extended to form securing-feet, and the same are interposed between the upper and lower terminals of the runners and are bolted to position through the medium of a pair of bolts 6 passed through the feet and through perforations formed in the terminals of the runners. A pair, or it maybe agreater number, of inverted U-shaped arches 7. rise from the runners and are interposed between the upper side portions 4 thereof, the lower ends of said arches being laterally-disposed forming securing-feet which, by means of bolts 8 are fastened to position upon the runners. At the point of intersection between the upper portions of the runners or bars 4 and the arches, bolts 9 are passed through and serve to connect the same. Inner strips 10, are located at the inner sides of the terminals of the arches and through the medium of the bolts 9 are also secured in position. These strips at their front ends are perforated as at 11 in line with the perforations 3 of the runners, and through the perforations 3 and 9 at each side of the machine bolts 12 are passed. These bolts receive the rear perforated ends 14 of a U-shaped draft-bail 15, which at its front end in the present instance carries an ordinary single-tree. The bail is crossed by a bar 16, having an opening 17, and if desired an ordinary draft-tongue may be bolted in position. The bail is preferably formed of a single piece of steel, and is provided near its eyes with bent portions 18, which are suspended upon the under sides of the terminals of the bail, as indicated at 19,the whole forming braces. In this manner a very strong and durable bail is provided though it will be obvious that other forms of bails or draftconnections may be substituted for the one herein shown.

Through the mediumof the bolts 8 that socure the rear standard in position upon the runners 1 there is pivoted a pair of cutters or knives 20, which may be swung in under the arches or between the runners or out from the same to any degree; These cutters or knives may be adjusted in their lateral position'or held in place in an inoperative position through the medium of bolts 21 with which the runners are provided.

A seat-board 22, surmounts the arches and is secured thereto. The seat-board is provided near its rear end with a slot 23, whereby through the medium of a bolt 24, a seat 25, for the accommodation of the driver may be adjustably secured. Foot supports or braces 26 extend from the side-bars 4 and have their inner ends bent to form hooks 27 for engaging between the strips 10 and sidebars and under the former. These rests are adjustable as is also the seat so that the machine is adapted for both tall and short men or boys.

The seat-board is further provided between the arches with a slot 29 at one side of which there is located a notched locking-standard 30. A bifurcated lever 31 has its terminals bolted or pivoted as at 32 between the strips 10 and upper portions of the runners or'sidebars 4, and the upper end of said lever promedium of which the stub-shafts may be adjusted to or from said runners, and thus the disks spread apart the desired distance.

Rods- 39 are removably'engag'ed with either the inner or outer peforations of the stub shafts-and at their front ends engage with perforations formed in the terminals of the bifurcatedlever 30. In order to effect such engagement in a-removable and convenient manner the'ends of the rod are bent'into hook-shape,as shown at 40.

The front end of the seat-board has'se cured theretoa hopper 41, which, as shown, is'divided into compartments 42 and 43, one for the accommodation of corn and the other for the'acoommodation of smaller seed; The hopper is-provided with a seed-spout of ordi nary construction and with a slide,- the same being controlled by an ordinary handle ex tending to a point convenient to the opera tor-,so that at the same time the cultivation of the corn or other cereal takes place, the operator may supply any deficiency in the planting theretofore carried on, o'r in other words, plant in any places that the planter may have skipped, and which will now be obvious by the plant not appearing at such point.

In operation the knives are adjusted laterally from the machine, in contradistinction to the position they occupy within the machine when the latter is not in operation, and the disks having been adjusted to throw more or less corn, the machine is started, strad dling the row. It will be seen that the disks operate upon the usual principle throwing more or less soil as may be desired upon the growing corn, thus forming a ridge, and the knives or cutters projecting a desired dis tance and being inclined will serve to sever and destroy all undergrowth or weeds that would otherwise be likely to choke or'im'pede the growth of the young corn.

Although I have herein shown and described various details of construction which form parts of my invention yet I do not limit the same to such minute details, but hold that I may vary them to any extent and manner within the skill of the ordinary mechanic, without departing from the spirit of my invention.

Having described my invention, what I claim is 1.
