of said gangs is more readily obtained than heretofore.

In order that the invention may be fully understood, reference will now be made to the accompanying drawings, in which:

Figure 1 represents a side elevation of my improved cultivator withone of the carrying wheels thereof removed. Fig. 2 is a plan view of the cultivator. Fig. 3 is an irregular vertical section on line III of Fig.2, of means for controlling lateral movement of the cultivator gangs. Fig. 4 is a vertical section of means for controlling vertical ad justment of the cultivator gangs. Fig. 5

, is a vertical longitudinal section on line VV of Fig. 2 of a rock-frame employed in controlling vertical adjustment of the cultivatorgangs. Fig. 6 is a cross section on line VIVI of Fig. 2, showing an evener-bar to allow either gang to follow a depression in the soil. Fig. 7 is a. section on line VII-VII of Fig. 2 of means for connecting the gangs together. Fig. 8 is a cross section on line VIII-VIII of Fig. 1. Fig. 9 is a cross section on line IXIX of Fig. 3. Fig. 10 is an elevation of a yoke adjustably carried by the rock-frame. Fig. 11

is a sectional plan view of part of the means disclosed by Fig. 7.

In carrying out the invention I employ a frame consisting of a pair of bars 1 secured at their forward ends to a tongue 2, a transverse arched-bar 3 secured upon bars 1 near their forward ends, a pair of braces 4 secured to the undersides of bars 1 and the terminals of bar 3, a pair of transverse bars 5 secured to the rear ends of bars 1, and an arched aXle 6 pivotally mounted in boxes 7 carried by bars 5, said axle being also mounted in a pair of wheels 8. Said frame, in the present instance, is provided with two gangs, each of which consists of a beam 9 provided with a bracket 10 and shovels or frame.

furrow openers 11, adjustably secured by slotted shanks 12 to the beam and its bracket.

The forward ends of beams 9 are turned upward and swiveled in a pair of clevises 13 provided with transverse sleeves 13 swiveled upon the transverse bar 3 of the By thus mounting the beams and the clevises, a universal joint is obtained whereby the gangs may swing freely both laterally and vertically.

Vertical swinging or adjusting of the gangs is controlled by two sets of mechanisms, one of which is controlled chiefly by the weight of the driver, and the other through a pair of hand-levers within convenient reach of the driver. The set of mechanisms first referred to, consists of a pair of seat-supporting levers 14 pivotally secured at their forward ends to bar 3 by a pair of U-bolts 15 and provided at their rear ends with a seat 16 which may be adjusted backward or forward and held in any of its adjusted positionsby a set-screw 16 a rock-frame 17 mounted upon a transverse rock-shaft 18 and provided near its rear end with a transverse yoke19 to which the seat-levers 14 are pivotally-connected by bolts 20, an evener-bar 21 carried at the forward end of the rock-frame by a bifurcated member 22, and a pair of cables 23 connecting the ends of said evener-bar to the gangs, see Figs. 1, 2, and 5 Seat-levers 14 consist of two sections 14 and 14', which former support the latter by a transverse bar 14. The forward ends of the sections 14 are pivotally secured to a pair of links 24 by bolts 25, to allow said sections to fold upon the frame when the cultivator is prepared for shipment. Links 24 are secured to sections 14 by bolts 26, and provided with series of holes 27, so that seat 16 may be adjusted up or down and held at its adjusted position by placing bolts 25 through the proper holes. This adjustment of the seat is to accommodate drivers of different height, so that they can conveniently reach a pair of foot-levers 28, hereinafter referred to. Sections 14* have series of holes 29 to receive bolts 20, and the rock-frame 17 has a series of holes 30 to receive a' bolt 31, whereby the yoke 19 is adjustably and pivotally secured to the rear portion of said rock-frame. By adjusting the yoke forward on the rock-frame the latter may be swung through a greater are and thereby give the gangs greater vertical sweep than when said yoke is adjusted to the rear of the rock-frame. The weight of the driver acting upon the gangs may be increased or diminished by adjusting the lower ends of cables 23 backward or forward, respectively, provision being made for this adjustment by flanges 32 secured to beams 9, and having holes 33 to receive bolts 3-1, whereby the lower ends of cables 23 are connected to said flanges, see Fig. 1. Rockshaft 18 is mounted in a pair of bearings 35 and provided at its ends with a pair of cranks 36 extending rearwardly and pivoted to a pair of links 37 for controlling a pair of toggles 38 pivotally connected at their ends to braces 4t and cars 39, which latter are secured to axle 6, the pivotal movement of which in its boxes 7, is controlled by extending or folding said toggles, see Figs. 1 and 12. The evener-bar 21 is pivotallv mounted upon a bolt 10 carried by the bifurcated member and permits either gang to drop lower than the other and thus follow depressions in the soil. At times, however, it is desirable to limit the pivotal movement of the evener-bar 21, or to entirely stop said movement, so I provide the bifurcated member 22 with two sets of holes 22 and 22 to receive a pair of pins 22. On placing said pins in the upper holes 22 said pivotal movement will be entirely overcome. The foregoing set of mechanism permits the driver to vary the depth of the gangs at will, as he can transfer all his weight to the gangs to force the same into the soil by pressing downward upon the foot-levers 28, or he may lift the gangs entirely from the soil to avoid obstructions or in turning around at the end of a furrow by transferring all his weight to the seat 16. When the weight is transferred to the seat 16, the seat-levers are rocked downward and tip the forward end of the rock-frame 17 upward so that it will lift the gangs through the intermediacy of the evener-bar 21 and the cables 23. As the forward end of the rock-frame tips upward it will straighten out the toggles 38, Fig. 12 and swing the lower ends of axle 6 backward to balance the uplifted gangs, and thus prevent the same from swinging the tongue upward.

The second set of mechanism whereby vertical adjustment of the gangs is obtained consists also of means for locking the gangs a predetermined depth in the soil, or for locking said gangs in raised position as when going to and from a field. Said second set of mechanism consists of two controlling levers 411 and 42, a rock-shaft 43 mounted in a pair of bearings 44.- secured to transverse bars 5, a sector 15 secured to shaft l3 by a set-screw 416 and carrying lever a1, a sleeve 47 mounted to turn upon shaft 43 and carrying lever 12 secured thereto by a set-screw 48, cranks 19 and 50 fixed to shaft 43 and sleeve 17 by set- screws 51 and 52, respectively, two pairs of rocker arms 53 pivotally secured at their lower ends to ears 5 1 and provided at their lower front portions with arms 55, a pair of rods 56 pivotally secured to the cranks 49 and 50 and extending loosely through the arms 55, a pair of ex pansion springs 57 loosely embracing rods 56 and interposed between the cranks and the arms, a pair of expansion springs 58 loosely embracing rods 56 and interposed between arms 55 and collars 59 fixed to the upper ends of rods 56, shafts 60 supported by transverse portions 61 of the gangs and provided at their upper ends with sleeves 62 to which the upper ends of the rocker-arms 53 are pivotally secured. When the controlling levers are pulled backward they force the gangs into the ground through the intermediacy of the intermediate mechanism, and by pushing said levers forward the gangs, of course, will be raised, or if desired, either gang maybe operated independent of the other by manipulating its respective controlling lever. Lever 41 may be locked in any of its adjusted positions by its latch 64 and a sector 65 loosely embracing shaft 43 and secured to the transverse bars 5, and lever 42 may be likewise locked in any of its adjusted positions by its latch 66 and the sector 45. Lever 412 can be controlled through the lever 11 and thus leave one hand free to drive the team, but when either lever is to be operated independently of the other, lever 42 is unlatched from the sector 45. Then it is desired to control the vertical adjustment of the gangs through the weight of the driver by the set of mechanism first described, instead of through the controlling levers, the latter are permitted to float by holding their latches out of engagement with their respective segments by links 67, pivotally secured to the upper ends of the levers and adapted to engage the handles of the latches. The springs 57 and 58 act as cushions and permit the gangs to slightly rise or lower on meeting obstructions or depressions in the soil when the controlling levers are in locked positions.

Shafts 60 have ball-and-socket connections 68 with the gangs, so that they may rock back and forth with the rocker-arms 53, and their upper ends are swiveled in the sleeves 52 to which, however, they may be locked by pins 69, attached by cables 70 to the uppermost of a plurality of cotter-pins 71, extending through the upper portions of shafts 60 to prevent the sleeves 62 from sliding up or down thereon. Pins 69 are assisted in holding shafts 60 from turning in sleeves 62 by a pair of pins 72 extending through openings 73 in the ball-and-socket joints 68, and

attached to adjacent portions of the gangs controlled either by the foot-levers 28 or a pair of hand-levers 75, which former are fixed by set-screws 76 to the lower portions of a pair of tubular shafts 77, while the latter are fixed to the upper ends of said tubular shafts by bolts 78. Levers are provided with latche's 79 adapted to engage a pair of sectors 80 fixed to shafts 60 by bolts 81.. Latches 79 are normally held in engagement with the sectors 80 by expansion springs 82 engaging rearwardly-extending lugs 83 so disposed that the driver may depress the same and disengage the latches from the sectors without releasing his grip upon the handles 84 of the levers. WVhen desired, however, the latches may be heldout of engagement with the sectors by slipping a pair of links 85 between the handles and the latches, said links being carried when not in use in notches 86 in the handles. Tubular shafts 77 are connected at their lower portions to axle 6 by a pair of toggles 87 and the ears 39. By interposing the toggles between axle 6 and shaft 77, the gangs can be readily shifted laterally by swinging the levers 7 5 to the right or left, and by providing the latches 79 and the sectors 80, said gangs can be locked in any of their laterally adjusted positions. By shifting the handlevers 75 apart, toggles 87 are folded and push the gangs apart as shown in Fig. 2, and by shifting said hand-levers toward each other the toggles are extended (Fig. 13) and push the gangs toward each other. By removing pins 69 and 72 from sleeves 62 and the ball-and-socket joints 68, respectively, each shaft 60 and its lever 75, can be turned as a unit when locked together by their latch 79 and sector 80, and the efiect will be the same as if the levers 75 were secured direct to the shafts 60, but. the gangs, of course, could not be locked when adjusted laterally in this manner.

At times it is desirable to hold the gangs together, so that one cannot easily swing laterally independently of the other, so I provide a connecting-bar consisting of a section 88 and a section 89, adjustably held together by a thumb-screw 90, extending through slots 91 in the overlapping ends of said sections and provided with a nut 92. The sections are adjustably secured to the undersides of the hand-levers 75 by pins 93, extending from said hand-levers through slots 94 in the sect-ions, and retractile springs 95 and 95 secured at their ends to pins 93 and 96 which latter depend from the outer ends of the sections, see Fig. 7. By loosening the thumb-screw the overlapping portions of the sections are free to slide upon each other and permit the gangs to be adjusted apart or toward each other, but when the two sections 88 and 89 are locked together the gangs will be practically held in fixed relation to each other.

The springs and 95*, however, permit either gang to be forced laterally independently of its companion. For instance, in shifting the right-hand-gang to the right, through its respective hand-lever 75, the spring 95, Fig. 7, expands and permits the connecting-bar and the left gang to remain stationary, and when swung to the left, it carries the connecting-bar therewith but expands the spring 95*, which also permits the left gang to remain stationary. The left hand gang may likewise be independently adjusted by shifting its lever 75 to the right or the left. Under certain conditions it is desirable to lock the gangs together so thatthey may be moved laterally at the same time, so I provide the connecting bar with latches 97 adapted to engage the studs 93 and thus prevent the hand-levers 75 from moving independently of each other or the connecting-bar.
