To all wkomnimdy concern:

' Be it known that I, CHARLES H. DE'RHAM, a

citizen ofrthe'United-States, residing at Corunnat in the county of Shiawassee, State of 5 Michigan, haVe.-invented certain new and use.

standard 27. This standard 27 is supported by a bracket 1l, similar to that which supports the standards of the blocking-knives, said .standard 27 being secured in place by the bolts 28, which pass through the sides-of said brackets and throughsaid standard.

By loosening the bolts 13, which secure the brackets carrying the standards of the blocking-knives and rotary disks, said brackets may be adjusted longitudinally of the beam 9 to regulate the space between each pair or set of the rotary disks and to enable.v the blocking-knives to be adjusted laterally with respect to the position of said disks, so that the sharpened forward edge 30 of said standard may stand contiguous to the face of the disk, and thereby prevent the wedging of any substance between said disk and standard.

` It'will be observed that the rotary disks or cutters 24 are arranged in pairs and the disks of each pail` spaced .by the interposed hub 26 from two to three inches apart, Aas desired.,

It will also be observed that the blockingknives 18 aresopositioned as to occupy the space between the outer faces of the opposed disks of each pair. By 'this arrangement as the .machine is drawn across the field the surfaceof the earth is cut through on each side of the beet-plants itis desired to cultivate, and the knives 18 block out the remaining plants between said pairs of disks, thereby leaving of the row only those plants which remain undisturbed between each pair ot' the rotary disks as the machine is .drawn along.

The rotary`dis'ks cutting into the earth as they do on'each side of the plants sever all earth crusts and clods, so thatthe blockingknives4 in their passage through theground cannot tear the earth and injure the plant that is left between said disks,'whil e said disks serve as a guard to prevent clods from shoving against the plants and the earth which is l thrown up by the'blocking-knives or cultivators from falling thereon, enabling a large area of beets'to be blocked in aperfect manner within a comparatively short time, thereby elfecting a great saving of labor.

The handles 29, which are shown as partly' i' broken away, are attached to the draft-bars 7 and enable the operator tocontrol the machine. By means of the engaging hooks 6 at the forward end ot' said 'draft-bars and the pivotal connection-B lbetween the rear horse dcfiect from the line of said row.

ends of said bars and the beam 9 said beam and the cutters carried thereby may be swung laterally of thc machine, so as to maintain the circular cutters at all timos straight with the row that is being blocked out should the It will also be evident that the 4operator by means of the handles may force the cuttingdisks into the ground where the ground is hard and when encountering soft ground may raise the cutters, so as to prevent them from cutting too deep.

When used as a cultivator, the blockingknives maybe changed for a shovel or tooth of any suitable form, will be understood.

Having thus fully. set forth my invention,

what I 'claim as new, and desire to secure by Letters Patent, is i ,Y

1. In a machine for the purpose set forth, the combination with the transportable frame, of the rotary cutters adapted to eut through the surface of the ground on each sideoi' the plant, said rotary cutters being positioned 'in the rear of the transportable frame, a flexible connection between said cutters and frame and the blocking-knives interposed between said rotary cutters to sever the plants between them.

2. In a machine for the purpose set forth,A the combination ot' the rotary cutters arranged in pairs to straddle the plant to beleft for cultivation, and the lateral blocking-knives interposed between the pairs of rotary cutters, said knives being positioned to work between said cutters in transverse alinement IOO blocking-knife vextending between the faces' j of said disks, each knife being independently 4 movable in the arc of a circle and independently adjustable i'fertically.

' 4. ,'In a'beet-blockng machine, the combi- IIO nation of the portable frame, the rotary cuttingdisks arranged in pairs, and mounted upon said frame, the blocking-knives interposed between the outer faces of the disks of each pair, said knives being adjustable independ ently of-said disks, a transportable frame,

and a flexible connectionbetween said frames. 5. In a beet-blocking machine, the combination with the axle and transporting-wheels,

of the transverse beam loosely connectedvto said axle in the rear thereof, rotary cuttingdisks laterally adjustable on the beam and arranged in pairs te straddle the beet-plants.,

and the adjustable blocking-knives interposed and extending between each pair of disks sub- 5 stantially asset forth. Y

6. In abeet-bloeling machine, the combiu nation with the transporting-Wheels and the beam connected tlleiewith, of the opposedd cutting-disks secured in pairsto said beam', a IO blockingdnife lnterposed between each pau' of said disks eaeb. knife being adjnsabie vesti cally and having independent mpvenienl; in the ae of a cirelebo change 'the angle ef the blade.
