T0 aZZ whom, t may con/cern.-

Beit known that I, AUGUSTIN ELLIS, a citizen of the United States, residing at Bedford, in the county of Lawrence and State of Indiana, have invented certain new and useful Improvements in Cultivators, of which the following is a speciiication.

The principal object of my said invention is to produce a cultivator in which the plows are adjustable toward and from each other, and in which the plow-beams are Inaintained in parallel relation at wh atever distance apart they may be placed. This object is accomplished by suspending the hangers upon the axle (or a transverse rod connected thereto or to the frame-work) in such a manner that they may be readily shifted from one position to another thereon, and combining therewith jointed levers which extend back and unite with standards extending up from the rear end of the plow-beams, and which also continue on to form the handles.

The invention further consists in certain details of construction and arrangements of parts, as will hereinafter be more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a perspective view of a cultivator embodying Iny said invention, the pole being broken away and the wheels shown in dotted lines; Fig. 2, a top or plan view of the same; Fig. 3, an enlarged plan of the jointed portion of one of the levers which operate the hangers and adjusting parts, on an enlarged scale; Fig. 4, a central sectional view thereof on the dotted line 4 4 5 and Fig. 5, a transverse sectional view on the dotted line 5 5, and showing especially the particular method which I prefer to employ in mounting the hangers upon the axle or shaft.

In said drawings, the portion marked A represents the axle or shaft of the cultivator, which is shown as of the variety known as an arched axle; B, the pole thereto; C, the hangers D, the plow -beams, and E the jointed levers by which the hangers and plow-beams are shifted from side to side in adj listing the plows toward and from each other.

The axle A is not. dissimilar to other arched axles, and needs no special description. Upon its ends are the usual wheels A, and running from points near said wheels to the pole B, or a cross-bar B thereon, are brace-rods Z9', by which the rigidity of the structure is maintained. It is united centrally to said pole by a cap or clip d. From alongside said cap or clip to the ends, or the points where it turns, are portions adapted to receive the hangers O, and upon which said hangers will freely slide or move.

The pole B is in itself an ordinary pole. It is secured to the axle A, as has just been described. Upon its rear end,which projects to the rear side of the axle, is a cross-bar B2, which is extended or is provided with wings b2, upon the ends of which the hinged lever is pivoted.

The hangers O are preferably mounted on the horizontal portions of the axle A, although they may be mounted upon separate shafts or a cross-rod secured to any portion of the frame-work, if desired. To their lower ends are connected the forward ends of the plowbeams, as is common. The upper ends of these hangers are preferably bifurcated, and pass astride the axle (or the rod or shaft) upon which they are mounted, and have rollers c placed thereon above and below said axle or shaft, as shown most plainly in Figs. 4 and 5. The faces of these rollers are concave, so as to fit upon the sides of the shaft and properly engage therewith, and also to permit the slight rotation of said shaft in relation to the hangers, which is desirable. This enables the hangers to be moved to any desired position with but slight effort on the part of the operator.

The plow-beams D are secured to the lower ends of the hangers C in an ordinary manner, and to said plow-beams are secured draftrods CZ, which extend forward and are attached to singletrees, which are preferably suspended from the cross-bar B as shown. To the rear end of said plow-beams, or to wings CZ thereon, are secured the shovels or plows D', and extending upwardly from near the points where said shovels or plows are attached are arms D2, the upper ends of which pass through slots in the handle portions of the hinged 1evers E, and upon the extreme upper ends of ICO these arms are nuts or caps cl2, by which they are held in place.

The jointed levers are in two parts, which are respectively pivoted to the wings of crossbar B2 by pivots e e2. One of these parts has a slot in the end which is next the other part, and said other part has a pin e, which engages in said slot. Those parts which eX- tend forward over the axle engage with upward projections c2 on the hangers C, and the other parts extend back and develop into the handles of the cultivators. The handle portions are preferably hinged at e3, as shown,to permit of the freer movement of the machine.

As is well known, it is frequently desired to vary the distance between the plows of a cultivator in operation to accommodate it to rows of various widths or plants of various sizes. It is desirable that in the adjustment of the machine the plow-beams should be maintained in parallel (or substantially parallel) relation, in order that the draft may be substantially directly forward from the plows. By the use of my invention the adjustment is effected by simply moving the handles to ward or from each other, which, by means of the engagement of the jointed leversE at the forward ends with the upward projection c2 on the hangers and at the rear ends with the upper ends of the arms D2, cause both ends of the plow-beams to be moved simultaneously and substantially to the same extent, thus maintaining the parallel relation, as above stated.

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

l. The combination, in a cultivator, of the plow-beams, hangers and armsfor said plowbeams, and jointed levers connected thereto at the front and rear, whereby by moving said levers both ends of said plow-beams are moved simultaneously, substantially as set forth.

2. The combination, in a cultivator, of the plow-beams, arms extending upwardly from said plow-beams, hangers whereby said plowbeams are connected to the axle or shaft, and jointed levers pivoted to the frame-work and connected at the forward and rear ends, re

spectiVely, with said hangers and said upwardlyprojecting arms, substantially as described, and for the purposeas specified.

3. The combination, in a cultivator, of the hanger C, suspended to the axle or a shaft, a plow-beam D, connected to said hanger and having an upwardly-projecting arm at its other' end, and a jointed lever E, pivoted to the frame-work and att-ached to said hanger and said upwardly-projecting arm,said lever being formed in two parts, which engage with each other by means of a projection and a slot, substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand and seal, at Crawfordsville, Indiana, this 31st day of May, A. D. 1889. I

AUGUSTIN ELLIS. [1.. s]
