Claim. 1. In a tilling implement, the com- 

 bination of a revolving cutter, a revolving 

 spade, and a sifting grate, substantially as de- 

 scribed. 



2. In a tilling implement, the combination 

 of a revolving cutter, a revolving spade, a sift- 

 ing grate, and a hilling attachment, substan- 

 tially as described. 



3. In a rotary tilling implement, the combi- 

 nation, with the revolving cutter and revolving 

 spade, of the side frames 27 28, forming bearings 

 for their journals and boxes which inclose the 

 driving train of gear wheels connecting the two 

 shafts, and forming, with the handles 29 30, 

 levers for controlling the depth of the spade 

 and cutter, and for lifting them from the earth 

 either separately or jointly, substantially as 

 shown and described. 



4. In a tilling implement, a revolving cutter, 

 revolving spade, wheels 10 n, side frames 27 

 28 and handles 29 30, the connecting bars 17 

 18, and ratchet segment 33, combined and ar- 

 ranged substantially as shown and described, 

 whereby said frames and handles may act as 

 levers of the first and second orders alternately 

 in controlling the movements of the imple- 

 ment. 



5. In a tilling implement, substantially as 

 shown and described, the combination, with 

 the revolving cutter and revolving spade, 

 wheels 10 11, side levers, and handles, of the 

 draft bars 17 18, which move independently of 

 the side frames or levers, and to which the 

 draught shall be applied at one of the adjusta- 

 ble attaching holes, whereby the thrust of the 

 revolving cutter into the earth is regulated, 

 and the fulcrum of the wheels 10 1 1 may be 

 varied along said bars to raise the revolving 

 cutter substantially as described. 



6. In a tilling implement, a revolving cutter 

 and a revolving spade combined together for 

 conjoint operation, the said parts being con- 

 structed and hung with relation to each other 

 so that the spades shall play within the spaces 

 afforded between the cutters, and the cutters 

 shall run close to the axis of said spade, where- 

 by the earth lifted by the spades shall be con- 

 fined thereon, substantially as described.

 Minn. Rotary Plows. Sep. 24, 1878. 

 Filed June 13, 1878. 



Claim. 1. In a rotary plowing implement 

 carried on draft-wheels, the combination of a 

 rotary plowing-wheel, K, having a concavo- 

 convex cutting-edge arranged next to the soil, 

 and without the interposition between it and 

 said wheel of other parts, and for traveling on 

 the bottom of the furrow, and having its flaring 

 concavity turned partly forward, therotatively- 

 adjustable and obtusely-bent axle I, carrying 

 the said plowing-wheel, and having thereon the 

 tapering collar J, and adapted at one end to 

 receive a wrench, and the axle-box F, verti- 

 cally adjustable with relation to the said 

 draft-wheels, the said box being provided with 

 a clamp for rendering the said axle either loose 

 or rigid therein, substantially as and for the 

 purposes specified. 



2. In combination, the caster-wheel S, 

 mounted on the rotary stock or carrier S', hav- 

 ing thereon the rigid notched collar h, the piv- 

 oted lever Q, applied to the frame carrying the 

 plow-disks, the bolt or slide/, carried by the 

 said lever, the fixed serrated plate R, the lever 

 U, pivoted to the lever Q, and the fixed loop 

 V, substantially as and for the purposes speci- 

 fied. 



3. In combination, the supplemental frame 

 E', provided with an axle-box, F', and carry- 

 ing a vibrating lever, Q', having on its lower 

 end the caster S, the removable half-axle B 

 and its draft-wheel, the removable dish-shaped 

 plowing-wheel K, the removable axle-box F 

 and its clamps, the removable obtusely-bent 

 axle J, and a locking device for engaging the 

 lever Q', substantially as and for the purposes 

 specified. 



4. The share K', arranged behind a rotary 

 concavo-convex or dish-shaped plow-disk, and 

 placed for cutting through and under the sod or 

 land next to the furrow turned therefrom by 

 the disk, substantially as and for the purposes 

 specified. 



5. A cutting blade or share mounted on a 

 vertically-vibrating caster-stock or carrier, in 

 combination with a rotary concavo-convex or 

 dish-shaped plow-disk, the said share being 

 arranged to cut under the sod or land before 

 the sod or land so cut is turned by the said 

 disk, substantially as and for the purposes 

 specified.
