To aXZ evwmz' may concern:

i Be. it known that I, CHARLES B. OARLEY a citizen of the United States, residing at Rochester, in .the eountyof Olmsted and State of Minnesota, have invented certain new and useful improvements in Oultivators; and I do hereby declare the'follow;

ing to be a full, clear, 'and exact description f of the invention, such as willl enable others.

skilled in the art to whichv it appertains to makeand use the same.

r`My invention relates to-improvements in cultivators, and particularly to wheelstraddle-row cultiva-tors; and, to this end, generally stated, it consists of the novel devices and combinations of devices hereinafter described and defined in tire claims. y

in the accompanying drawings,l which illustrate the invention, like characters indicate like parts throughout the `-several views.

Referring to the drawings,

Figure 1 is a view of the improved culti-- vator in longitudinal central section taken onthe irregular line w1 x1 of Fig. 2, some parts being shown in different positions by means of broken lines;

Fig. 2."is a View, partly in rear elevation,

partly in. transverse section taken on the line .r2 x2 of F ig. 1; and `lFig` 3 is a fragmentary longitudinal central section. taken on the irregular line m3 x3 of Fig. 2.

The numeral 1 indicates a pair of large traction wheelsA journaled on a crank axle 2 having anintermediate radially oiset arch 3. A frame 4 is balanced on the arch 3 and has on its side members a pair of depending bearings 5, in which the arch 2 is pivitally mounted. Extending from the front end of the frame 4, is a draft pole 6 and suspended from the rear end thereof, is aseat 7. The

frame 4 isA balanced and the axle 2 turned into diiferent angular positions, with respect to the frame 4, for the purpose of ad.

vancing or setting backA the wheels 1 to change the elevation 'of the frame 4, by suitable connections and levers of well known arrangement, and for the purpose of this case, only a portion 'of which is illustrated. Of these connections and levers, the numeral 8 indicates levers pivotally secured to the front end of the frame 4 and are connected to the axle 2, on each side of the arch 3, by a pair of straps 9. One of the .levers 8 and straps 9 at their pivotal connection, are connected by a link 10 to thelower end of a hand lever 11, intermediately. fulcrumed on Specification of Letters Patent.

the arch 3. Coperating with the hand lever 11 for locking the same in dierent positions, is a lock segment 12 secured to the arch 3.

Two pairs of depending hanger cranks are secured to the arch 3 and each comprises aiixed member '13 and a movable member 14 vhaving radial sliding movementone upon the other. ,Themembers 13 are channelsliaple in cross section to slidably receive the members 14 and theinembers 13 of each pair have their channels turned toward each other. Each pair of hanger crank'membcrs13 is connected by a tie'strap 15, which holds the same into position in the members 14. integrally formed with the upper end of each of' the two other hanger crank members 13, is a sleeve 16. These sleeves 16 ,embrace the radial members of the arch 3 and are frictionally clamped thereon p bolts 17. integrally formed with the upper end of each of the inner hanger crank members 13, is a horizontal sleeve 18, which embraces the 'horizontal portion of the arch 3 and is frictionally clamped thereon by groimd-working tools, as shown four in number, seton quarters and -each comprising a shovel or hoe 25, a socket member 26 and a breaking or connecting pin 27. Those portions of the shafts 20, between the members 14, are square in cross section to slidably receive correspondingly formed hubs on the socket members 26. Set screws 28 hold the sockets 26 axially spaced on the shafts 20. The breaking pins 27 connect the shovels 25 with the sockets 26. Obviously, the squared interlocking engagement of, the sockets 26 with the shafts 20 holds the ground-working tools for 'rotation with the shafts 20 and circumferentially spaced thereon.

Each shaft 2O and the ground-working tools carried thereby are radially adjusted, with respect to theagears 23, by a pair of levers 29, 'intermediately fulcruxned on lock segments 30 integrally formed, one with each sleeve 18. The short end of each lever 29 is pivotally connected to the underlying 'the surface of the land in ditches,

tie strap l5 by a link 31. On each lever 29, is a latch 321:011 cooperation with the respective lock segment 30. Obvionsly,by manipulating the levers 29, the connected pairs of hanger crank members 14 may be radially adjusted.

When the arch 3 is in a true vertical position, the shovels 25 enter the ground to their greatest depth. If it is desirable to have the ground-working tools enter the ground a less depth than that when the arch 8 is in a true vertical position, said arch may be adjusted by the lever 11 to change the angularity thereof, and thereby move the hanger cranks circumferentially, as indicated by broken lines in Fig. l. During the circumferential adjustments of the hanger cranks, the pinionsD 22 are continuously in mesh with the gears 23. By manipulating the levers 29 to slide the hanger crank members let inward on the members 13, the ground-working tools may be completely Withdrawn from the ground and, at the same time, the pinions 22 are moved out of mesh with the gears 23.

In case one of the shovels 25 should strike a stone, stump or other obstruction, and thereby place undue strains on the cultivator, the respective pin 27 Will break to relieve the strain. Among the many advantages my present invention has over ordilnary cultivators, is that instead 'of leaving it leaves the same level, thus avoiding washing during heavy rains. It also digs up weeds, quack grass and other noxious growth and leaves the same on top of the ground, where the same 'will be killed by the heat of the sun. Owing to the action of my improved cultivator, thesame will not drag and scatter noxious growth over the surface ot the ground, Where it is liable to again take root.

The above described invention, while extremely simple, can be applied to various different makes of cultivators with little Work.

i What I claim is 1. A wheel cultivator having a pivotally mounted crank axle, traction wheels on the crank portions of the axle, a hanger secured to the arch of said axle for concentric movement with the traction wheels, a ground- 'working tool carried byl the hanger, and

means for adjusting the crank axle circumferentially to vary the depth of the cut of said tool.

2. A wheel cultivator having a pivotally mounted crank axle, traction Wheels on the crank portions of the axle, a longitudinally adjustable hanger secured to the arch ot said axle for concentric movement with thc traction Wheels, a ground-Working tool carried by the hanger, and means for adjusting the ,crank axle eircumferentially to vary the depth of the cut of said tool.

3. A Wheel cultivator having a pivotally ,mounted crank axle, traction wheels on the crank portions of the axle, a longitudinally adjustable hanger secured to the arch of said axle for concentric movement with the traction Wheels, a revoluble ground-working tool carried by the hanger, means for driving said tool from one ot the traction wheels, and means for adjusting the crank axle circumferentially to vary the dept-h of the cut of said tool.

il. A vvheel cultivator having two pairs ot' radially extensible hanger cranks, a horizontal shaft carried by each pair ot hanger cranks, a plurality et axially and circumferentially spaced grouml-wm'kin tools carried by each of said shafts. means for independently driving said shafts from the traction wheels, means cranks circumferentially with the traction wheels to vary the cut of the ground-working tools, and means for radially adjusting the hanger cranks to independently carry the ground-working tools into and out ot the ground.

5. In a wheel cultivator, the combination with a trame, ot' a crank axle having a radially offset intermediate portion on which said frame is pivotally mounted, a pair of traction wheels journaled on the crank axle, a pair of hanger cranks secured to the crank axle, a lgrounfl-working tool carried by the hanger cranks, and means for securing the crank axle to the frame in diiierent angular adjustments to circiunicrentially adjust the hanger cranks together with the traction wheels and thereby vary the depth oi' the cut ot' the ground-working tool.

G. ln a wheel cultivator. the combination with a frame, of a crank axle having a radially oilset intermediate portion on which said Jrframejs pivotally mounted, a pair ot' traction wheels journaledpon the crank axle, a pair of lradially adjustable hanger cranks secured to the crank axle, a ground-working tool carried by the hanger crank, means for radially :u'ljusting the hanger cranks to carry said tool into and out of the ground, and means for securing the crank axle to the frame in different angular adjustments to circumferentially adjust the hanger cranks together with the traction wheels and thereby vary the depth of the cut of the groundworking tool.

ln testimony whereof I allix my signature in presence of two witnesses.
