DIRTPROOF HUB FOR CULTIVATOR DISKS Filed 001;. 17. 1931 Patented Sept. 13, 1932 BOY R. REA, OF BEAVER COUNTY, OKLAHOMA.
:ornrrnoor Hun FOB oULrIvAroR DISKS Application filed October 17, 1931. Serial No. 569,478.
This invention relates to agricultural implements and pertains particularly to an improved hub structure for disk or lister Cultivators.
The primary object of the present invention is to provide an improved hub and boxing for cultivator disks which is absolutely dirt and sand-proof.
Another object of the invention is to provide an improved cultivator disk structure in which the disk is provided with a central aperture has secured thereto a supporting hub carrying spindle which is enclosed in an improved boxing which is designed to prevent dirt from entering between it and the supporting spindle, the hub being of a spider character to extend across the aperture of the disk, through which the boxing and spindle pass, so as to permit dirt to pass through the disk opening.
Other objects and advantages of the invention will become apparent as the description of the same proceeds and the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims. f
In'the drawing Figure 1 is a view 1n longitudinal section through the hub structure and disk of the present invention;
Figure 2 is a view in end elevation of the hub viewed from the outer side of the disk.
Referring now more particularly. to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates a cultivator disk of the usual type with the exception of the fact that this disk is provided with a materially larger central aperture 2' then disks of the usual type.
Secured to the outer or convex face of the disk to surround the aperture 2, is a ring 3 which carries the arms i which in turn are formed integral with and radiate from a centrally located hub 5; As shown these arms 4 at their outer ends are turned to extend axially of the hub toj oin the ring 3, thus positioning the radially extending portions thereof in a plane removed a substantial distance from the ring of the plane 3 and consequently positioning the hub 5 a substantial distance forwardly of the ring.
The hub 5 is located upon the convex side of the disk and it has secured therein by means of a rivet 6 or any other suitable se'-' curing means, one end of a steel spindle bolt 7 which passes {through the aperture 2 of the disk and a substantial distance beyond the inner or concave'face thereof where it terminates in the head 8.
Surrounding the spindle 7 is a metal box ing 9 which at its inner end has formed thereabout the integral outwardly extending surrounding flange 10 which is positioned adjacent the-arms 4 of the hub supporting the spider, and extending inwardly in'the same plane as the flange 10, is aflange 10 which is of slightly larger diameter than the spindle. At its opposite end the boxing is reduced and screw-threaded, as indicated at 11, for the reception of a grease cup or cap 12. As shown the head 8 of the spindle positions against the outer end of the boxing 9 and is covered by the grease cap 12.
Surrounding the spindle 7 "between the same and the boxing, is a wooden sheath or liner which acts as a bearing for the spindle and which is of a length to fit snugly between the head 8 of the spindle against which one end bears, and the inwardly extending flange 10 of the boxing against which its other end bears. Surrounding the spindle and bearing against the flanges'lO and 10 isa felt disk 14: which is preferably of the same overall diam eter as the flange 10 and is interposed between the same and the arms 4. a
I In use the assembled disk and hub structure isattached to the cultivator frame by securin 'the usual supporting clamp of the frame about the boxing 9. The dirt which is picked up by the cultivator disk as it falls therefrom 1 will pass through the aperture 2 and be deflected outwardly by the flange 10 of the boxing passing out between the arms 4 of the hub supporting spider structure, to the ground upon the outer or convex side of the disk. It will be seen from the foregoing that with a structure of the character herein described, no dirt can reach the bearing surface between the spindle and the bearing lining l3 and, therefore, these parts can be kept clean 1y lubricated at all times and free from the wear which is ordinarily caused by the action of sand and dirt when the same gets'between such bearing surfaces.
Having thus described the invention, what is claimed is 1. The combination with a cultivator disk having an opening axially therethrough, of a hub, means connecting the hub with a disk to support the hub concentric with said opening and at a point removed from the adjacent face of the disk, a supporting spindle secured at one end in the hub and extending through the disk opening, a boxing for said spindle, and means carried by the boxing at the end adjacent the hub for deflecting downwardly earth passing through the disk aperture.
2. The combination with a concave cultivator disk having an opening formed axially therethrough, of a hub, supporting elements connecting the hub with the convex face of the disk and maintaining the same co-axially with said opening and in a plane removed a substantial distance from the convex disk face, said means connecting the hub with the disk being open, a spindle connected at one end in said hub and passing through said disk opening, a boxing enclosing said spindle, and a flange surrounding the end of the boxing adjacent the hub and disposed upon the convex side of the disk at a point removed therefrom whereby dirt passing through the aperture of the disk will be deflected downwardly by the flange through said open hub supporting means.
3. The combination with a concave cultivator disk having a central aperture therethrough, of a hub disposed concentrically of the aperture upon the convex side of the disk, arms connecting the hub with the disk and supporting the same in spaced relation thereto, a spindle secured at one end in said hub and passing through the disk aperture, a boxing surrounding said spindle and having one end closed, and a flange surrounding the other end of the boxing and disposed within the confines of said arms between the hub and the disk body.
4. The combination with a concave cultivator disk having a central aperture therethrough, of a hub disposed concentrically of the aperture upon the convex side of the disk, arms connecting the hub with the disk and supporting the same in spaced relation there to, a spindle secured at one end in said hub and passing through the disk aperture, a boxing surrounding said spindle and having one end closed, a flange surrounding the other end of the boxing and disposed within the confines of said arms between the hub and the disk body, and a body surrounding the spindle and interposed between said flange and the arms and bearing against the flange.
5. The combination with a concave cultivator disk having a central aperture therethrough, of a hub disposed concentrically of the aperture upon the convex side of the disk, arms connecting the hub with the disk and supporting the same in spaced relation thereto, a spindle secured at one end in said hub and passing through the disk aperture, a boxing surrounding said spindle and having one end closed, a flange surrounding the other end of the boxing and disposed within the conflnes of said arms between the hub and the disk body, and a bearing body surrounding the spindle within the boxing.
6. The combination with a concave cultivator disk having a central aperture therethrough, of a hub body disposed upon the convex side of the disk, arm members extending radially from the hub and connected at their ends with the disk and maintaining the hub concentric with the aperture in the disk and spaced a substantial distance from the same, a spindle secured at one end in the hub and extending therefrom through the disk aperture and having a head formed upon its other end, a boxing surrounding the spindle and bearing at one end against said head, a flange surrounding the other end of the boxing and disposed beyond the convex side of the disk adjacent the hub, a cap member covering said head and engaging the adjacent end of the boxing, and a wear element interposed between the flange of the boxing and said arms.
7. The combination with a concave cultivator disk having a central aperture therethrough, of a hub body disposed upon the convex side of the disk, arm members extending radially from the hub and connected at their ends with the disk and maintaining the hub concentric with the aperture in the disk and spaced a substantial distance from the same, a spindle secured at one end in the hub and extending therefrom through the disk aperture and having a head formed upon its other end, a boxing surrounding the spindle and bearing at one end against said head, a flange surrounding the other end of the boxing and disposed beyond the convex side of the disk adjacent the hub, a cap member covering said head and engaging the adjacent end of the boxing, a wear element interposed between the flange of the boxing and said arms, and a wear body surrounding the spindle within the boxing.
In testimony whereof I hereunto aflix my signature. ROY R. REA.
