DISK BLADE.
To all whom it may concern Be it known that I, OTTO BERT BULLARD, a citizen of the United States, residing at Spalding, in the county of Greeley and State of Nebraska, have invented new and useful Improvements in Disk Blades, of which the followingis a specification.
This invention relates to cultivators and more particularly to disks for disk cultivators, harrows, and like machines.
The principal object of the invention is to provide a simple and eificient structure of this character which will effectively break up the earth so that the use of a drag or roller will be obviated.
Further objects of the invention will appear as therfollowing description is read in connection with the accompanying drawing. which forms a part of this application, and in which:
Figure 1 is an elevation of the disk. Fig. 2 is an edge view thereof. Fig. 3 is a detail sectional view.
Referring more particularly to the drawing, the disk is constructed of an ordinary dished plate 1 provided with a plurality'of radial slots or cuts 2 which produce the radial projections 3. Each of these projec- Specification of Letters Patent.
Patented June 1, 1915.
tions is twisted so as to bring one radial edge thereof laterally out of alinement with the opposite edge in the form of a windwheel or like structure. The edges of the projections are connected together by substantially U-shaped members 5 having angular lips 6 as shown in Figs. 2 and 3. These connecting members 5 join the ofiset and normal edges of adjoining projections 3 and lie in radial planes. The disk of course is provided with a central aperture to receive the axle and is keyed to said axle in any suitable manner.
What is claimed is:
A cultivator disk comprising a circular dished plate having a plurality of radial projections, each provided with a lateral 01T- set edge and a normal edge, and V-shaped plates having oppositely extending lips, said lips being attached to the offset and normal edges of adjoining projections.
In testimony whereof I affix my signature in presence of two witnesses.
