This invention consists in the construction of a dropping 

 tube, to which adjustable or reversible arms are attached ; 

 also, a bent bar, with stationary and reversible arms, upon 

 which are disks or wheels placed obliquely to the line of 

 draught, having cone-shaped bearings for equalizing the side 

 draught and preventing friction on the axle, the cone being 

 secured to the arm by a pin, and may be adjusted by shift- 

 ing it to vary the width of tlie disks. 



Claim. — I. — The two serrated or plain disks W \V, 

 oblique to the line of motion, upon stationary adjustable and 

 re\tisililc arms ,; ,7, attached directly to the dropping tube 

 T, and the stationary and adjustable arms attached to a 

 piece P P, for the purpose of covering grain, cultivating and 

 hoeing vegetables in different manners, as set forth. 



2. — The application of the cone bearings B, and cap d 

 and pin i in the hub H and disk W, when placed or run-

Each plough is made of a single plate of steel, concavo-con- 

 vex in shape, the edge sharpened with the bevel on the outer 

 side. The ploughs are arranged in oblic|ue series so as to clear 

 each other's furrows and have an obliquity on their axes 

 relatively to the line of draft, to give the width of the fur- 

 row slice.
