To the leverH is pivotally attached the lever P of the bell-crank variety, the short arm of which is connected by the link 1) to the spring-dog O, that engages notches on the sector h, and by means of which the lever may be adjusted and held in the position re quired. The rim of the wheel F is divided circumferentially into two parts, between which are secured the cutter-blades I, that form the oolter. The spokes of the wheel are preferably small tubes, and alternate spokes support opposite sides of the rim and are sufficiently flexible to admit of drawing the two parts of the rim toward each other by bolts in securing the cutter-blades. These blades are provided with slots '6, through which the bolts j pass. By means of these slots the blades I may be adjusted, so as to extend the distance beyond the periphery of the wheel that is required to sever the turf. The ends of the blades may be made male and female, as shown in Fig. 5, for mutual lateral support. When the boltsj are screwed up tight, the blades I are held firm, as in a vise. By loosening the bolts the blades may be ad justed at any time, and by withdrawing the bolts the blades may be taken out and sharpened by an ordinary blacksmith. "hese blades are of thin tempered steel, and are therefore durable, and are operated with little power. The wheel F is located at such a distance from the plow on the landside that the colter will sever the turf the width of a furrow from the plow.

In plowing it is desirable that the furrow be turned over and laid down smoothlyin the trench of the adjacent previously-turned furrow; but, instead of this, the furrows, when turned down, are inclined to overlap the adjacent furrows. To remedy this difficulty, jointers are provided to slice off the top edge of the furrow when in nearly a vertical position, so that the severed part will first fall into the trench, carrying with it any straw or litter that may be on the furrow, after which the remainder of the furrow, as it is turned over, fits snugly down in the trench, so that the plowed field presents that smooth even surface that is the delight of practical farmers.

My improvcdjointer consists of the blade K, provided with the shank k, that may be bent at any angle required, and that terminates in the ball is, that fits in the socket Z of the supporting-arm L. This arm is bent at right angles, and the upright part provided with the slot L, through which the bolt passes that secures the arm to the plow, and by means of which the arm is vertically adjustable. A slot, Z, and a bolt, Z is provided. By means of the former the sides of the socket may be separated slightly to admit the ball k, and by means of the latter the sides of the socket may be drawn together, so as to grasp and secure the ball in the position in which it may be placed in adjusting the blade K. "With this construction the jointer is easily and universally adjustable.

M is the seat, supported by one or more springs, m, secured to the frame in any convenient manner. A draft-arm, 0 may be attached to the under side of the plow-beam.

In place of the tongue 0, thills may be substituted when required.

What I claim is- 1. In a wheel-plow, the combination, with a frame, a short axle pivoted near its outer end to said frame, and a land-wheel journaled to said axle and provided on its peripherywith adjustable cutters, of a lever for moving the axle horizontally, substantially as set forth.

2. In a wheel-plow, the combination, with a frame, a short axle pivoted near its outer end to the-frame and supported at its inner end between guides, a wheel, and cutters adjustably secured to said wheel, of a lever for moving the axle horizontally, substantially as set forth.

3. In a sulkyplow, the combination, with the adjustable arm L, provided with an adjustable socket, Z, of the jointer K, provided with the ball is, adapted to operate in said socket, by means of which the jointer is made universally adjustable.

4. In a wheel-plow, the combination, with aframe, a short axle pivoted nearits outer end to the frame and supported at its inner end between guides, a wheel j ournaled on the axle, and cutters secured to the periphery of the wheel, of a lever for moving the axle horizontally, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 21st day of January, 1884,.
