Specification of Letters Patent.

Patented Oct. 29, 1 907.

Application filed January 19 1907. Serial No. 353,165-

To allu'hom it may concern:

Be it known that I, ELLIS L. Bthcli, a citizen oi the ifnited Slates, residing'at Bentley, in the countyoi Sedgwick and State of hansas, have invented certain new and useful Improvements in Sand-Proof Diskliu bs, of which the following is a specification.

This invention relates to disks such ascrnployed for drills, cultivators, plows and the like" and deals more particularly with the mountings, whereby dust and other foreign matter is excluded from the bearings.

For a full description ol'the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

\vlllL'. the invention may be adapted to different forms-arid conditions by changes in the structure and minor details, without departingfrom the spirit or esscnl ial features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure l is a. perspective view of a disk provided with mountings embodying the invention. Fig. 2 is a sectional view of the disk and its-mountings. view similar to Fig. 2 showing the parts separated to bring out more clearly their relation and the structural details. v

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters- 4 The disk 1 may be such as employed in agricultural machinery either as a colter, cultivator or opener.

The numeral 2designates a hollow stem which is provided at-. one end with a flange 3, the same being confined between circular plates 4 and 5 which are fastened to eaclr-other and to the disk 1. The plate 5 has a tubular extension 6 which projects through the disk and terminates in an outer flange 7. A spindle 8 projects from the plate 4 and is mounted in the hollow stem 2 in which it obtains a bearing. The flange 3 while confined between the plates 4 and 5, yet is not clamped but is adapted to rotate freely between said plates. The outer plate 4 has an inner flange 9 which embraces the outer edge of the plate 5 and obtains a close lit against the convex side of the disk 1 to prevent entrance of dust, or other foreign matter. The middle portion of the plate 4 is pressed outward to form a recess iii to accommodate Z le llangc 3 so as to prevent binding of said flange when the plates 4 and 5 are drawn together and secured tothe disk 1. An oil cup 10 is fitted to the hollow stem 2 for lubricating the spindle 8.

Fig. 3 is a To obtain a tight joint between the tubular extension 6 and the hollow stem 2 so as to prevent the entrance of dust, a box 11 is clamped to the stem 2 and its inner end has a flange. 12 which embraces the flange 7 at the outer end of said tubular extension 6. The box 11 is composed of sections which are fitted about the stem 2 upon which it is bolted, or clamped.

The flange 12 embraces the flange 7 without binding the same, thereby admitting of the disk 1 rotating freely, while at the same time insuring a close joint between the flanges 7 and 12 sufiicient to exclude the entrance of sand, dust and the like which would tend to grind and wear away the bearings.

Having thus described the inventioinwhat is claimed as new is:

1. In combination with -a cultivator disk having a tubular extension, a hollow stem having a flange, a spindle mounted in the hollow stem and having a plate which is secured to the said disk-and confines the flange of the hollow stem, and a box clamped to the hollow stem and having a close fit with the aforesaid tubular extension to exclude foreign matter.

2. In combination a disk having a tubular extension projected therefrom and having a flange. a hollow stem mounted in said tubular extension of the disk and provided with a. flange, :1 spindle in the hollow stem, a plate fast to the spindle and secured to the disk and confining the flange ot'saidhollow stem, and a box clamped to' the. hollow stem and having a flange cooperating with the. flange of the aforementioned tubular extension to insure the formation or a tight joint.

3. In combination, a disk, a hollow stem on which the disk is mounted, and having a flange at one end, com panion plates secured to the disk and confining between "them the flange of said 'hollow stem, the inner plate hav ing a tubular extension provided with a flange, a spindle projected from the outer plate and mounted in said hollow stem, and a box clamped upon the hollow stem and having a flange coiiperatlng with the flange of the aforementioned tubular extension to secure a close joint.

4. In combination a disk, a hollow stem provided with a. flange, inner and outer plates confining between them, the flange of the hollow stem and securod'to each other and to the disk, a tubular extension projected from the inner plate through ,the disk and having a flange. the

said outer plate having an inner flange to encircle the said inner plate and having its middle portion pressed outward to receive the flange of the hollow stem, and a.

sectional hox clamped about the hollow stem and having a flange embracing the flange of the aforementioned tubular extension to secure a close joint therewith.

In testimony whereof I ailix my signature in presence of two witnesses.
