These lugs gin the movement of the frames by mechanism hereinafter described are guided by the curves f of the frame A.

The frames F rock on their bearings independent of each other, and are thus free to adjust themselves to any inequalities in the ground.

On each shaft H is placed a sleeve '5, and t" is a nut screwed on said shaft and adapted to bear against said sleeve and bind it against the lug g to allow the said frames F to rock less easily when occasion may require.

J ournaled in the vertical portion. (1 of the bar I) is the shaft 1, the forward end of which is provided with the lever J, the ends of which are connected by means of the rods or bars J with the brackets h. To the other end of the bar D is secured the lever K by means of an adjusting-nut], and said lever upon opposite sides of its fulcrum is pivotally connected with the lugs 7L2. The lever K is provided with a suitable locking-catch to engage the rack-bar E and hold said lever and the frames F in their adjusted position. The movement of the lever changes the inclination of the frames F in relation to the line of draft.

M is a footlever pivoted to the tongue, and its hooked end is connected by means of a cord or chain M with the inner end of the diskframe F, there being two fo0t-leverson e up on each side of the tongue, one for each diskframe-said foot-levers being for the purpose of raising the inner ends of the disk-frames, as will be readily understood.

The device is simple, easily adjusted, and will be found to be very efficient in operation.

\Yhat we claim to be new, and desire to secureby Letters Patent, is-

1. The combination, with the frame A, of the longitudinal shafts supported at their ends on the frame A,the frames F, free to oscillate on said shafts, and the disks carried by a shaft arranged transversely of the frames F, substantially as and for the purpose specified.

2. The combination, with the frame A and the two independent harrow-frames free to es cillate independently of each other on longitudinal shafts, of the transverse shafts journaled in said frames and carrying the disks, the shaft I, and connections between said shaft and the longitudinal shafts of the harrowframes, substantially as shown and described, and for the purpose specified.

3. The combination, with the frame A, formed with the curves f, of the harrow-frames provided with the lugs g, and the means for adjusting said frames, substantially as and for the purpose specified.

4. The combination, with the frame A and the tongue, of the independentrocking harrow-frames, the pivoted foot-leve1's, and the chains connecting said levers with the inner ends of the barrow-frames, substantially as and for the purpose specified.

5. The combination, with the frame A and the two independent harrow-framcs, of the shafts of said harrow-frames, the shaft 1, the operating-lever on one end of said shaft l, and the rods connecting the shafts of the harrowframes with the said lever and shaft- I, substantially as and for the purpose specilied.

In testimony whereof we atlix our signatures in presence of two witnesses.
