To (11 whom it may concern:

Be it known that I, OHARLEY DE FREEsE, a

citizen'of the United States, residing at Westpoint, in the county of Tippecanoe and State of Indiana, have invented certain new and useful Improvements in Cultivators; and I do declare the plows or the cultivator-shovels to vary the depth at which the same are to work.

A further object is to provide an adjusting mechanism of this character which may be quickly and easily applied to the various forms of cultivators.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement ofparts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a cultivator, showing the application of the invention, one wheel of the cultivator being removed. Fig. 2 is a rear elevation of the same with one wheel removed. Fig: 3 is avertical sectional View through the device and a portion of the cultivator-axle. Fig. 4 is an enlarged side view of the attachment removed from the cultivator. Fig. 5 is a horizontal sectional view of the same, taken on the line with the Wheelspindle; and Fig. 6 isan enlarged detail side view of the outer end of the wheel-spindle, showing the construction of the adjustable tap for holding the wheels" on the spindles.

Referring more particularly to the drawings, 1 denotes the cultivator, 2 denotes the axle, and 3 the supporting-wheels of the same. These parts may be ofjthe usual or any desired construction. Secured to the outer ends of the axle is a guide-frame 4, said frame consisting'of a vertically-disposed plate 5, having formed onits outer side guideways 6. On the upper end of the frame is arranged a segmental rack 7 said rack' being also provided with a series of transversely-disposed apertures 8. On the inner side of the plate 5 is formed a laterally-projecting socket 9, into which is adapted to be inserted the end of the axle 2, said axle having been provided with a transversely-disposed bolt-hole 10,

which when the same is inserted into the socket 9 is adapted, to 'aline with holes 12, formed'in the walls of the socket, and through said alined holes is adapted'to be inserted a bolt 13, whereby the frame 4: is secured to the end of the axle.

Slidably mounted'in the guideway 6 on the plate 5'is a spindle-supportingplate 14:, said plate being provided with a laterally-projecting socket 15, in which is formed alined apertures 16. Into the socket 15 is adapted to be inserted the inner end of the wheel-spindle 17, said spindle being provided adjacent to its innerend with a transversely-disposed aperture 18. This aperture18 is adapted to be brought into alinement with the apertures 16, and through said apertures is inserted a bolt19, whereby said spindle is secured within the socket 15. In the socket 15 is formed an annular recess, which is adapted to receive the inner end of the Wheel-hub, thus forming a sand band or guard to prevent the entrance of dirt in the hub and axle. On the spindles 17 is journaled'the supporting-wheel 3 of the cultivator.

7 Pivotally mounted onthe upper end of the .Which, is pivotally connected the upper end of a link 23, the lower end of said link being pivotally connected to the spindle-plate 14:, whereby when said lever 20 is swung in one direction or the other the spindle-plate, together with the spindle and cultivator-wheel, will be raised or lowered, thus causing the cultivator blades or shovels to plow deep or shallow, as may be desired. In the apertures 8 of the segmental rack are adapted to be insertedcotter-pins or keys 23. Said pins or keys are adapted to limit the movement of the hand-lever in one direction or-the other, thus forming a stop for said lever to enable the, same to be repeatedly brought to the same position without the necessity of carefully observing that the same has reached this point, this arrangement being used when it is desired to adjust the lever back and forth between certain positions.

On the outer end of the wheel-spindles 17 is arranged an adjustable wheel-securing, tap

24, consisting of a sleeve or collar 25, on the inner end of which is formed an annular offset flange 26, adapted to project over the outer end of the wheel-hub. In the sleeve or collar 25 are formed two series of spirally-disposed apertures 27,arranged on opposite sides of the sleeve. The apertures of one series are directly opposite or in alinement with corresponding apertures of the other series, said corresponding apertures being adapted to be brought into alinement or coincidence with a transversely disposed aperture formed through the end of the spindle, and through the alined apertures in said sleeve and spindle is adapted to be inserted a pin 28, thereby holding said tap on the end of the axle. By forming the alined apertures in the sleeve 25 in a spiral manner the sleeve may be adjusted upon the end of the spindle by pushing the same inwardly or outwardly and turning the tap until the apertures in the opposite side of the same are brought into alinement with the apertures in the end of the spindle, thus permitting the sleeve and tap to be secured in its adjusted position. This adjustment of the tap permits the wear on the wheel or other parts to be compensated for.

By providing a cultivator with an adjusting attachment of this character the supportingwheels may be quickly and easily raised or lowered to permit the cultivator blades or shovels on either or both sides of the cultivator to plow deep or shallow, as may be desired.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what A I claim as new, and desire to secure by Letters Patent, is

A cultivator of the class described having an arched axle having dmvnwardlyturned and outwardly-extcnded crank ends, guideframes having sockets on their inner sides near their lower ends into which the outwardly-extended crank ends of tln arched axle are secured, said guide-frames extending upwardly and being formed at thei r upper ends with segment-racks, spindle-supporting plates mounted in said guide-frames for vertical movement and provided in their outer sides with sockets in which the inner ends of the spindles are secured, levers fulcrumed to said segment-racks, links connecting said levers to said vertically-movable spindle-supporting plates, and means coacting with the segment-racks to lock said levers and spindlesupporting plates at any desired vertical adjustment.

In testimony whereof I have hereunto set my hand in presence of two subscribing \vitnesses.
