UNITED STATES GEORGE CORDES, OF BARABOO, W'ISCONSIN.

FIELD-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 471,209, dated March 22, 1892.

Application filed November 6, 1891. Serial No. 411,056. (No model.)

To all whom-it may concern:

Be it known that I, GEORGE CoRnEs, a citizen of the United States, residing at Baraboo, in the county of Sauk and State of Wisconsin, have invented certain new and useful Improvements in Field-Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and .use the same.

This invention relates to improvements in field cultivators or harrows; and the novelty will be fully understood from the following description and claim, when taken in connection with the annexed drawings, in which Figure 1 is a plan View of my improved harrow or cultivator with the draft-beam partly broken away. Fig. 2 is an end elevation, partly in section and partly broken away. Fig. 3 is a diametrical section of two of the pulverizing-disks with the shafts in position, and Fig. 4 is a perspective View of one of the disks removed.

Referring by letter to said drawings, A indicates the frame, which may be formed of wood, metal, or other suitable material, and is preferably of a rectangular form. This frame may be provided with a suitable seat for the driver, and is also provided with a hinged or pivoted beam 13 for the attachment of the draft-animals when two are employed, or a pair of shafts may be used with asingle horse.

0 indicates a beam or bar arranged centrally of the main frame and is designed to serve as a bearing for the cutter-shafts.

D indicates the shafts, which may be composed of stout rods and hear at their outer ends in the lateral bars a of the main frame and are also sustained in the center bar 0, as shown, suitable bearings being provided for the purpose. These rods or shafts are designed to be readily removable from the bearings and are prevented from undue longitudinal play by a head I) at one end and a nut c at the opposite end, although it is obvious that other means might be employed for this purpose, and it is also obvious that instead of having these shafts or rods extend the entire width of the frame they may be of such a length as to extend from the central cross-bar to the lateral beams or bars only. These rods or shafts D are threaded, as shown at (1,6, and f, to receive lever-nuts E and to also rc= ceive the nuts 0.

F indicates sleeves, which are bored longitudinally to receive the shafts or rods D and are of rectangular or of other angular form in outline.

G indicates the cutting or pulverizin g disks. These disks are of a peculiar construction and are of approximately saucer shape. Said disks may be cast or formed from stout sheet metal or other suitable material, having a central flat portion g, from one side of which a central rectangular sleeve or collar H proj ects, and from the central flat portion, which is of circular form in outline, flare the cutting or pulverizing blades h. These disks are placed upon the sleeve F, which is in turn placed upon the shaft D, and are arranged with their concavities facing the same direction, so that the free edge of the rectangular sleeve H may abut against the outer sides of the flat portion g of the next disk and determine the distance at which the disks are to be arranged from each other upon the sleeves F. These pulverizing-disks are arranged upon the shafts so that the disks on one shaft will pass the spaces formed by the disks on the opposite shaft, and vice versa. The disks and also thesleeve are stayed upon the shafts at one end by means of nuts I and are adjustably secured at their opposite ends by means of washers 7c and the threaded levernuts E. It will thus be seen that should any one of the disks become impaired or injured it may be readily removed and replaced by another by simply freeing the shafts from the hearings in the main frame and manipulating the lever nuts so as to let off the desired disk and then sliding the cutters or disks back upon the sleeves and adjusting the latter upon the shafts.

Having described my invention, what I claim is In a cultivator or earthpnlverizer, the com bination,with the pulverizing-disks of approximately saucer shape, having the rectangular collars projecting on their concaved side from the center thereof, of the rectangular sleeve receiving said disks, with the collar of one disk bearing against the outer side of another disk, the shaft receiving said sleeve, and suitable means for reniovably and adj ustably securing the sleeves and disks to the shafts, substantially as specified. [o

In testimony whereof I affix my signature in presence of two Witnesses.
