capable of being easily steered by the hand of the driver, and embodyin such a, construction that it is light of draftgis not likely hereinafter explicitly vreferred to.

- their function to brace to be choked with trash, andis generally well adapted to withstand the usage to which wheeled cultivators are-ordinarily subjected.

Another object is the provision of a wheeled construction susceptible of being readily '.converted from a cultivator to'a planter and vice versa.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof: v I

Among other elements my novel cultivator comprises a main frame 1, an axle 2 and ground wheels 3. The main frame 1 is of general U-shape in plan, with the blght of the loop foremost and the ends thereof connected to the axle, it being understood in this connection that the 'main frame is arranged forward of the axle. The said main frame 1 includes upper and lower; bars 4, bolts 5v connecting the same, and tubular sections 6 mounted on the bolts '5 and interposed between the bars 4 and having for the bars and to maintain the same in spaced relation. The axle 1 to 6, to which reference 2 2 includes a horizontal intermediate portion,

the intermediate portion and spindles extending outwardly from the said pendent portion, the ground wheels 3 being mounted on the said spindles in the ordinary well known manner.

The cultivator also includes a tongue 7, and a doubletree 8 connected to the tongue in front of the main frame 1 and equipped with singletrees 9. 'At an intermediate point of its length the tongue is pivotally connected to the forward portion of the main frame 1, a clip 10 being disposed over the tongue and a pivot bolt 11 being extended through the clip 10, the tongue 7 and the forward portion of the main frame 1. The rear end of the tongue 7 is equipped with a rearwardly extending metallic bar 12 which is adapted to play between two transverse straps 13 that are fixed to the main frame 1 and constitute a race for the bar 12 when the rear portion My improved cultivator is designed especially to be operated by a man who has lost one or'both legs, and toward this end I provide for the steering of the cultivator a hand lever 14:. The said hand lever 14 has its handle portion disposed in such proximity to the drivers seat 15 that the driver is enabled with his hand to conveniently manipulate the lever. From a point to the right and in a horizontal plane above the drivers seat 15, the steering lever 1 1 extends transversely of the cultivator under the beam 16 of the seat 15, and is provided with a bifurcated portion 17 that straddles and is pivotally connected at 18 to one side bar of the main frame 1. From the said point of pivotal connection 18, the outer arm of the steering lever: 14 extends forwardly about the proportional distance illustrated, and is pivotally connected at its forward end to the outer end of the link or links 19, the inner end or ends of which are pivotally connected to the rear end of the tongue 7. In order that the operator may adjustably fix the main frame 1 and the tongue 7 with respect to each other, 1 provide on one side for cooperation with the said rack, so'that the cultivator may be held at the desired angle, for instance on ahillside where the is relieved of the necessity of holding the cultivator in working position. The detent 21 is connected to a rod 22 inwhich is a disk coupling 23 in which works a cam 24, designed to lock the detent out of engagement with the rack 20, when desired. 7

At 25 are the beams of the cultivator, two in number, and at 26 are ti-shaped bars of whieh there are two to each beam 25. Carriedby and bolted 27 to each pair of bars 26 is a gang of groundavorking devices 28 which are preferably in the form of curvilinear spring teeth, as illustrated. The said gangs are right-hand and left-hand, respectively, and in conjunction with each gang is employed a strap 29 that is interposed between and connected to one end of one bar 26 and is also pivotally connected at an intermediate point in the length of the adjacent beam 25 as indicated by 29*, Figure Manifestly by reason of the construction of :the gangs of ground-working devices or ing forward portions.

teeth 28, there is no liability of the gangs becoming choked with trash, the S-bars 26 serving to Work the devices of teeth 28 backwardly and forwardly. As illustrated, the beams 25 are provided with upwardly reach- At 30 are braces on the. beams. It will also be observed that fixed with respect to and arranged transversely of the forward portion of the main frame 1 is a tubular member 31. The said transverse tubular member 31 preferably extends between the bars 1; of the main frame, and is disposed and held in shackles 32, each of which has its arms arranged between the frame bars tand connected thereto through the medium of a bolt 33 that extends through the upper and lower bars 4 and the arms of the shackles as shown. Telescopically arranged in the tubular member 31, and connected thereto by bolts 3% are preferably detachable rod sections 35., the outer ends of which are bifurcated, as indicated by 86. When desired, each of the rod sections 35 may be provided with a plurality of apertures for adjustment purposes.

An arch member 37, desi 'ned to hold the n 1 gang of ground-working devices together is employed, as best shown in Figure 2. For

,adjustment purposes, the said arch member is preferably provided in each end portion with a plurality of apertures, so that the gangs of ground-working devices may be positioned at various distances apart.

At 38 are upright springs that actagainst the ends of the arch member to press the plows to the desired extent into the ground.

The said springs ar interposed and maintained between the main frame 1 and the end portions of the arch member 37, as illustrated.

The cultivator also includes levers 39 through the medium of whichthe gangs of ground-working devices are raised when desired. The said levers are of course hand levers. They extend straight upwardly from the axle, and their lower portions extend forwardly from the axle to the spring 40.

It will be apparent from the foregoing that a cultivator of the construction set forth is susceptible of being operated to advantage and with ease by a man who has lost either one or both legs.

By reference to Figures 7 and 8, the manher of using the wheeled construction described in the formation of a two-row planter will be understood, when it is stated that the rod sections 35 before described are removed from the ends of the tubular member 31. The said rod sections are removed together with the beams 25 and allof the cultivator parts connected with the said beams 25, and in lieu of the said rod sections 35, I employ, as shown in Figures 7 and 8, rod sections 35*, which rod sections 35 are telescopically arranged in and are connected to the tubular member 31. The said rod sections 35 have connected thereto planter beams 25*. Each of the said planter beams 25 is equipped with a furrow-forming disk and with a seed-box 51, a fertilizer box 52, a ground wheel 53, the usual or any appropriate mechanism operable by the ground wheel to discharge seed from the box 51'and fertilizer from the box 52 and covering devices 54. By placing planter beams 25 equipped as stated, in'the wheeled structure, and connecting the arch member 37 to the beams 25*, and arranging the springs in the manner before described with reference to a cultivator, the structure will be converted from a cultivator to a two-row planter; it being understood in this connection that the planter mechanisms are of right and left-hand type, festly the planter mechanisms may be made comparatively light, inasmuch asthe springs may be depended upon to hold the same to their work. It will also be manifest that when desired, the machine may be expeditiously and easily reconverted from a planter into a cultivator.

extending forwardly from the axle, said main frame being of U-shape in plan with the bight of the loop foremost, transverse spaced straps fixed to the main frame in rear of respectively. Mani the forward end thereof and forming between them a raceway, a drivers seat supported on the main frame, a tongue pivotally connected at an intermediate point in its length to the forward portion of the main frame, means carried by and extending rearwardly from the tongue and movable in the raceway between the said straps, a hand steering lever arranged in convenient proximity to the drivers seat and fulcrumed at an intermediate point of its length to one side portion of the frame and extending forwardly from said connection; the major portion of said lever extending from the said pivotal connection transversely of the main frame, and a connection between the forward portion of the said hand lever and the rear portion of the tongue.

2. A hand steered wheeled construction, comprising an axle, a main frame connected to and extending forwardly from the axle, wheels on the axle, a drivers seat supported by the main frame, a tongue pivotally connected at an intermediate point in its length to the forward portion of the main frame, a hand steering lever having its free end or handle portion disposed at the right of and in convenient proximity to the drivers seat and extending transversely across the main frame and pivotally connected at an intermediate point in its length to the left-hand side portion of the main frame and extenddrivers seat on the main frame, a tongue pivotally connected at an intermediate point of its length to the forward portion of the frame, a horizontal rack carried on the lefthand side portion of the main frame, a horizontal hand steering lever having its free end portion or handle disposed at the right of the drivers seat, said hand lever extending transversely across the main frame and pivotally connected to the left-hand side portion from said point of connection, link means connecting the forward portion of said lever and the rear portion of the tongue, and a detent and detent-operating and controlling means carried by the lever.

In testimony whereof I affix my signature.
