WILLIAM SOBEY, OF RACINE, WISCONSIN.

CULTIVATOR- SPECIFICATION forming part of Letters Patent No. 794,129, dated July 4, 1905.

Application filed December '7, 1903. Serial No. 184,031.

To all whom it may concern:

Be it known that I, WILLIAM SOBEY, a citi- Zen of the United States, and a resident of Racine, county of Racine, and State of Wisconsin, have invented certain new and useful Improvements in Cultivators, of which the following is declared to be a full, clear, and exact description.

The invention relates to wheel-cultivators which carry independent shovel-beams for opposite sides of the plant row. In such cultivators the gang-beams are swung at their forward ends to the main frame and are adjustably supported at their rear ends. The axle usually comprises an elevated horizontal section swiveled to the frame and depending wheelsections, so that the axle is arch-shaped to straddle the row. The wheel-sections of the axle are usually laterally adjustable with reference to the horizontal central portion to accommodate the cultivator for rows of different width. Suitable adjusting shift mechanism or regulating devices are provided for the gang-beams, which are preferably under control from the drivers seat and arranged to be releasably locked in any adjusted position.

The present invention seeks to provide simple and effective shifter mechanism which is entirely independent of the regulating devices for the gang-beams and by which the position of the depending portions of the arched axle may be readjusted with reference to the frame, and thereby properly balance the machine for operators of different weight. The selected means does not require the removal of securing-bolts or like expedients, but by simple shift accomplishes the desired end. A suit.- able actuating-lever carried on the frame enables the driver to control the shift at will from his seat. The upper ends of the stubaxles are mounted in peculiar fashion, so that they can be adjusted not only laterally for different Widths of tread, but through their swiveled connections with the main frame can quickly readjust in the line of draft, according to the balance established for the driver at his seat.

A further object of the invention is to provide a simple and effective arrangement for vices for the gang-beams and the adjustingshifter for the stub-axles.

The invention also provides an effective form of swiveled connections for the cultivator-beams by which the latter may be readily adapted for either level or pendulum swing.

The purpose is also to simplify the union of the separate parts of the arched axles with the frame of the machine; and the invention consists in the features of construction, arrangements, and combinationsof parts set forth in the following description, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of acultivator with the present improvements applied. In this figure for the sake of clearness the near wheel is broken away and the draft-evener shown in section. Fig. 2 is a plan view with certain parts omitted. Fig. 3 is a detailview, part in elevation and part in section, of the arched axle and its connections with the frame. Fig. 4 is a detail plan view of the connections between the frame and the sections of the arched axle. Fig. 5 is a detail bottom view of the same. Fig. 6 is a detail section on line 6 6 of Fig. 3. Fig. 7 is a detail section on line 7 7 of Fig. 3. Fig. 8 is a detail view, partly in section and partly in elevation, of the adjusting shifter for the stub-axles. Fig. 9 is a detail view, partly in elevation and partly in section, of the forward swiveled connections for the gang-beams. Fig. 10 is a detail section of the connection shown in Fig. 9. Fig. 11 is a detail front view thereof. Fig. 12 is a detail view in elevation of the swiveled connections for the gang-beams at the rear, and Figs. 13 and 14 are detail sections thereof, taken in plans at right angles to each other.

In the usual manner the carrying-wheels 15 are journaled upon spindles at the lower horizontal terminals of the arched axle. Each depending stub-axle or wheel-section 16 has at its upper end an inwardly-projecting horizontal portion 17, which fits snugly within the horizontal tubular crown section 18.

Brackets 19 are mounted upon opposite ends of the horizontal axle-section 18 and are provided with solid-ring portions 20 and splitring portions 21, which embrace the ends of the horizontal axle-section. Bolts 22 extend between the ends of the split-ring portions 21 and serve to securely clamp the brackets 19 in position. Each of the horizontal portions 17 of the axle-sections 16 adjustably extends through a collar 23, which sets within a semicircular slot or recess 24 in the under face of the adjacent bracket 19 and is held thereby against longitudinal shift. Set-screws 25, threaded through the collars, hold the wheelsections in adjusted position. The brackets 19 and collars 23, clamped, respectively, to crown-sections 18 and to the horizontal portions 17 of the axle-sections, as described, serve to securely connect the separate sections of the arched supporting-axle. At the same 'time'since collars 23 may freely rotate in the recesses 24 the depending wheel-sections 16 may swivel freely within the horizontal tubular section 18. The tread of the cultivator-wheels can be varied at will in keeping the width of the plant row by adjusting the wheel-sections 16 through the collars 23 and tubular axle-section 18 and clamping the same in such adjusted position by set-screws 25. The brackets 19 also preferably serve as connections between the arched axle and the frame of the cultivator and for this purpose are provided at their outer ends with upright and horizontal flanges 26 and 27, forming seats for the side bars 28 of the frame. These flanged portions 26 and 27 preferably diverge rearwardly (see Figs. 2 and 4) in keeping with the arrangement of the side bars and the rearwardly-extending supports 29. The supports 29 are U-shaped in section and rest, as shown, upon the horizontal projections or flanges 27 of the brackets 19, and the forward ends of such supports are adjustably secured to the side bars 28 by straps 30. The riders seat 31 is carried upon a cross-bar 32, of spring metal, adjustably secured at its ends to the rear portions of the supports 29. The forward converging ends of the side bars 28 are securely fastened to the pole 33. The draftevener 34 is pivotally supported upon the under side of the pole and aflords suitable attachment for the swingletrees.

Split collars 35 are secured by bolts 36 to the lower ends of the depending wheel-sections 16 of the arched axle, and to the bolts 36 are pivoted the rear ends of the brace-links 37. The forward ends of the latter are pivotally connected to the lower ends of the shifter rock-arms 38, which are fixed upon the ends of and depend downwardly from the shifter.

rockshaft 39. This shaft extends transversely across the machine at its front portion and is journaled at opposite ends in suitable bearing-boxes 40. The bearing-boxes 40 are provided at their inner ends with upstanding-lugs 41, grooved to fit the side bars 28 of the machine-frame and firmly secured thereto by bolts 42. The means for actuating the shifter rock-shaft preferably comprises a hand-lever 43, bolted at its forward end to an extension 44 on the hub of one of the rock-arms 38 and extending rearwardly within reach of the rider.

Means for locking the shifter mechanism in any of its adjusted positions preferably comprises asegmental rack 45, fixed to the end of one of the journal-boxes 40 adjacent the shift-lever, and a cooperating spring-held latch 46, mounted to slide within a bracket 47 on the side of the shift-lever 43, said latch being arranged to engage the teeth of the segmental rack 45. A trip 48 for releasing the latch 47 is pivoted near the end of the hand-lever 43 and is connected to the latch by a link 49. By means of the shifter and operating connections the positions of the wheel-sections of the arched axle relatively to the frame may be quickly and easily adjusted and locked in adjusted position, so that the leverage of the drivers weight upon the pole and other parts in front of the axle is correspondingly adjusted, and in this way the parts may be positioned to properly balance the machine with riders of different weight. Moreover, the adjustment may be easily and readily effected from the riders seat.

To the under side of the pole and in front of the draft-evener is fixed the transverse cross-shaft or fore-reach 50, upon which are mounted sleeves 51. These sleeves are free to rotate upon the cross-shaft 50, but are adjustably held against longitudinal shift thereon by collars 52 set within slots in the sleeves 51 and held in position by set-screws 53. Each of the horizontal sleeves 51 is provided with a pair of depending lugs 54, between which extends a forwardly-projecting lug 55 upon a vertically-disposed sleeve 56. A bolt 57, extending through the lugs 54 and 55, holds the vertical sleeve 56 in place. Upstanding lugs or projections 58 and 59 upon the horizontal and vertical sleeves 51 and 56 are arranged adjacent each other and are connected by a bolt 60, which extends through an arcshaped slot 61 in the ing 58.

The lug 55 is elliptical in section or tapers toward its edges, and the bolt 57 loosely fits the opening in this lug, so that when the nut on bolt is loose the sleeve 56 may oscillate from side to side to a limited extent upon the pin 57. By tightening the nut on bolt 60 the vertical sleeve 56 is of course held against oscillation. The round upturned ends of the cultivator-beams 62 extend through the vertical sleeves 56 and are adjustably supported therein by collars 63, which are provided with recessed flanged portions 64, arranged to engage an annular flange or lip 65 upon the lower end of the sleeve 56. The collars 63 are secured to the ends 61 of the gang-beams by set-screws 66. The height of the forward ends of the gangbeams maybe adjusted through the collars 63 and sleeves 56 and then held in adjusted position by the set-screws 66. At the same time the forward ends of the gang-beams are vertically swiveled within the sleeves 56, so that the gang-beams may swing horizontally within the sleeve 56 to a limited extent. At the rear each gang-beam 62 is connected to the lower end of a suspension-rod 67, the upper curved end of which is pivoted to the outer end of an upwardlyextending radius-arm 68. The-heel of the radius-arm terminates in ahorizontal sleeve 69, (see Fig. 3,) which is journaled upon a pivotbolt 70, passing through cars 71 on the upper face of the adjacent bracket 19., Shovels 72 are secured in the usual manner by shanks 73 to the gang-beams, and the supportingrods 67 are provided with the usual operatinghandles 7 4t.

The joint between the lower ends of the suspension rods 67 and the gang-beam 62 is formed as more clearly shown in Figs. 12, 13, and 1th. Each gang-beam consists of separate connected members, and a bracket 75 is pivoted to a cross-bolt 7 6, extending between the separate members of the beam. A sleeve 77 extends through the bore of the bracket 75 and between the members of the gang beam, so that the latter cannot be drawn together sufficiently close to prevent the free pivotal movement of the bracket. The ends of the pivoted portion of the bracket are somewhat conical in outline and set within similarly-shaped recesses in pieces 78, which are preferably grooved, as shown upon their outer faces, so as to fit snugly against the sides of the separate members of the gang beam. The lower end of the suspension-rod 67 is pivotally connected to the bracket by a bolt 79. A second bolt above the bolt 79 extends through a hole in the suspension-rod and through a segmental slot in the bracket 75. These pivotal connections for the for ward and rear ends of the gang-beams may be adjusted to give either what is known as the level swing or the so-called pendulum swing. All the changes may be made by simply tightening the nut on one bolt and loosening that on the other. For example, if the nut on the bolt 80 is tight, so that the bracket 75 and suspension-rod 67 are rigidly secured together, and the nut on bolt 60 loose, so that the vertical sleeve 56 is free to oscillate from side to side, the, gang-beams 62 will swing in the arc of a circle as they are shifted to and fro by the feet of the operator within the stirrups 82that is to say, the gang-beams rise as they approach the end of their lateral swing. On the other hand, if the nut on bolt 60 is tight, so that the vertical sleeve 56 cannot oscillate,

and the nut on bolt 80 is loose the gang-beams will then swing in a horizontal plane with their forward ends turning within the sleeves 56. The first adjustment described gives the so-called pendulum swing and the second the level swing. At the same time these joints for supporting the gang-beams permit the free up-and-down movement thereof as they pass over the ground and as they are thrown into and out of operative position.

The regulating devices for each gang-beam preferably comprises a heavy spring 83, connected by a chain 84L to the upper end of the radiusarm 68. The forward end of each spring 83 is connected to the upper arm of the shifter 85, which is loosely journaled to rotate upon the shaft 39. (See Fig. 8.) Each shifter is provided with a recessed flange 86, arranged to engage an annular lip 87 upon the inner end of the adjacent bearing-box 4:0, and is held thereby against longitudinal shift. To the lower arms of the shift-levers are connected links 88, which extend rearwardly through openings 89, formed in upwardly-projecting portions upon the brackets 19. These links 88 are provided at their rear ends with handles 91, by which they may be readily controlled from the drivers seat, and upon their under edge with rack-teeth 92, arranged to engage the edges of the openings 89 to hold the links and the regulating devices in adjusted position.

It will be observed that both the regulating devices for the gang-beams and the shift mechanism for the stub-axles may be easily and eon-' venientl y regulated from the drivers seat and that each of these adjustments is entirely independent of the other. The independence of these separate shift mechanisms is essential,

since it is often necessary to adjust one without effecting the adjustment of the other. In operation the wheel-sections are first adjusted to properly balance the weight of the rider, and the regulating devices for the plow-beams are then free to be independently adjusted as may be desired. The brackets 19 are provided with rearwardly -extending notched projections 93, within which the suspension-rods 67 are seated when the shovel-beams are in raised position.

It is obvious that numerous changes may be made in the details of structure without departure from the essentials of the invention.
