To (ZZZ whom it may concern.-

Be it known that I, JAMES ANDERSON BURT, a citizen of the United States, and a resident of Gunnison, in the county of Bolivar and State of Mississippi, have invented certain new and useful Improvements in Riding-Cultivators, of which the following is a specification. My invention is an improvement in ridingcultivators; and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure 1 is a plan view of my improvement. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of the frame. Fig. 4 is a detail perspective view of the central plow-beam. Fig. 5 is a similar view of one of the lateral beams. Fig. 6 is a detail perspective view of the slotted blocks to which the plow-beams are attached. Fig. 7 is a detail of the screw-threaded rod and bracket for adjusting the drawbar, and Fig. 8 is a detail perspective view of the manner of attaching the shank of the plow to the beam.

In the practical application of my invention I provide a frame comprising the longitudinal bars a and the cross-bars a a the cross-bar a connecting the longitudinal bars near the rear end thereof, while the front bar a connects them at approximately the same distance on the opposite side of the axle, leaving projecting portions of the longitudinal bars, forming shafts between which a horse may be hitched.

A shaft B, rectangular in cross-section and arranged with its widest dimension in a vertical plane, is secured upon the longitudinal bars by means of the clips I), and braces I) connect the sides of the ends of the shaft with the sides of the longitudinal bars. The ends of the shaft B are ofiiset vertically to form cranked portions 1), upon which are journaled the wheels 6 A plurality of blocks C, provided with horizontal slots 0 for receiving the shaft and vertical slots 0 for a purpose hereinafter described, are mounted upon the shaft and are provided with a set-screw 0 for fixing the blocks with respect to the shaft. A vertical plate a is slidably mounted within the vertical slot, the lower end of the plates being provided with a loop 0 engaging the plow-beam D, and upon the block is a toothed segment 0 having pivoted thereto a rocking lever 0 one of the arms of the rocking lever being connected, by means of the spring a with the plow-beam and the other arm being provided with a spring-actuated tooth c for engaging the segment. A grip c pivoted to the arm and connected by a rod 0 with the tooth, is provided for manipulating the same.

The plow-beams are three in number-a central beam D and lateral beams D. The central plow-carrying beam comprises a horizontal portion d, engaged by the loop 0 on the vertical plate, a downwardly-curved rearward portion d, provided with slotted ears (Z and an upwardly-turned front portion (1 having therein a series of alined perforations d The plow-point E is of any desired construction, and the upper end of the shank thereof is provided with a perforation registering when the point is in position with the slots in the ears (P. A bolt 6 traverses the alined openings, the end thereof being engaged by a nut for securing the parts in their adjusted position. The lateral beams D differ from the central beam in that they carry an additional plow E. The additional plow E is carried by a socket e integral with the plate 6 which is bolted to the side of the beam, the plate being spaced away from the beam a sufiicient extent so that the loop (1 on the vertical plate may be received therebetween.

Brackets F are arranged upon the lower faces of the longitudinal bars, the brackets comprising a pair of parallel spaced members f connected to the longitudinal bars and braced by braces f X extending from the botof perforations f adapted for engagement by a pin f 6 of a clevis f connected by a pin f 8 with one of the perforations in the upturned portions (1 of the plow-beams.

It will be evident from the description that by connecting the clevises in different openings in the upturned portion and in the plate that the front ends of the plow-beams may be adjusted vertically and horizontally, while by rotating the rods f 2 the plate f may be raised and lowered in the brackets, thus raising and lowering the plows to and from the ground. The central plow-beam is provided with a horizontal extension d at the front end thereof, bolted to the bar and provided at its free end with a hook (1 to which are connected the doubletrees c1 Swingletrees (Z are connected to the doubletrees in the usual manner, one swingletree being arranged between the shafts and the others at the sides thereof.

A plate-spring h is secured to the cross-bar a and upon the free end of the spring is a seat II.

It will be evident from the description that by means of the rocking levers c the plows may be elevated clear of the ground to avoid stumps or rocks and that they may be adjusted to cut at any desired depth by lifting and depressing the plate f and by changing the point of attachment of the clevis to the plate the horizontal distance of the plows may be varied to correspond with different widths of rows. The provision of the shafts permits of easy manipulation of the cultivator in turning and also supports the front end of the cultivator. By connectingthe doubletrees to the central plow-beam the draft is more equally distributed and more nearly in line with the pull upon the plows.

The provision of the plate secured to the beam and sliding vertically in the block maintains the beam always in a plane perpendicular to the frame and shaft during the movements of adjustment, whether vertically or transversely, serving as a guide for this purpose.

From an inspection of Fig. 1 it will be seen that my improved cultivator is arranged to cultivate the ground between the rows instead of on each side thereof, as in the ordinary cultivator. For this reason there is an odd number of plow-beams, and the beams are arranged without any space between them to receive the row of corn. By depressing the central beam and elevating the plows E on the lateral beams the entire sur face of the soil in the depression between the rows may be cultivated.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is i 1. In a cultivator and in combination, a frame having shafts at the front thereof, a shaft secured to the frame, and having cranked ends, wheels j ournaled on the cranked ends, a plurality of blocks slidablymounted' upon the shaft and provided with vertical slots,

means for fixing the blocks with respect to the shaft, plates slidably mounted in the blocks, and provided with loops at their lower ends, plow-beams having downwardlycurved rear ends, and upwardly-turned front ends supported in the loops, a toothed segment fixed to the block, arocking lever pivoted to the segment and having a spring-actuated latch upon one of its arms for engaging the segment, a coiled spring connecting the other arm with a plow-beam, brackets supported on either side of the frame, a draw-bar mounted in the brackets, means for raising and lowering the draw-bar, an adustable connection between the upturned en s of the nected with one of the plow-beams, and a doubletree connected with the hook.

2. In a cultivator and in combination, a frame, a shaft secured transversely of the frame, wheels on the ends of the shaft, a plurality of plow-beams connected by their front ends to the frame, and means for raising and lowering the beams, comprising.
