A UNITED STATES JACOB DEINES, OF OLMI'I'ZJKANSAS.
HARROW-DISK SUPPORTING FRAME AND SHAFT.
Applicationfiled August 17, 1927. Serial No. 213,595.
This invention relates to harrow disk shafts and supporting frames therefor and 001m prises essentially a frame adapted to rotatably carry a shaft between the ends thereof,
said shaft being suitably constructed to permit a plurality of harrow disks to be separately attached thereto. An important object of the invention is to provide means enabling the shaft to be easily and quickly detached from the frame whereby to permit the removal and replacement of the disks thereon.
A further object is to construct the shaft of a tubular formation whereby to provide a lubricating reservoir therein for lubricating the bearing supporting the shaft to the frame.
A still further object is to provide a device of this character of simple and practical construction, strong and durable, arranged so as to permit the parts to be readily assembled and disassembled, thus providing for 4 the removal of the disks from the shaft whenever it is found necessary to replace or sharpen the same, which is inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the special construction and combination of the various parts constituting the invention, reference being had to the accompanying drawings forming part hereof, wherein Figure 1 is a top plan view showing one type of harrow disk frame with the disks in mounted position thereon.
Figure 2 is an elevational view with one end of the shaft and frame, shown in longitudinal section, and,
Figure 3 is an end elevational view thereof.
Referring to the drawing in detail, I provide a harrow disk frame comprising a horizontally disposed frame member 5, which may be of a V-shaped formation as shown in Figure 1 whereby to carry the disk at the respective ends of the frame in an angular relation with each other and having an attaching plate 6 arranged at each end of each section of the frame for securing the upper ends of a pair of vertically disposed shaft supporting members 7.
One of the shaft supporting members 7 is arranged at each end of each of the frame sections whereby to support the opposite ends of the shaft 8, each shaft supporting member comprising a pair of spaced parallel bars 9 secured at their upper and lower ends by bolts 10, each of the bars 9 having hubs 11 formed on the opposite fac esthereof. inwardly arranged bar 9 carries a bushing 12 Within the hub thereof, upon which is rotatably supported the tubular shaft 8, the end of the shaft being inserted between the hub 11 and the bushing 12.
Upon the shaft 8 is secured a plurality of harrow disks 13, each of said disks having a hub 1 1 through which the shaft 8 is inserted and secured thereto for rotation with the shaft by means of set screws 15. Each of the end disks 13 are spaced from the adjacent bar 9 by means of a flanged collar 16, said collar being attached to the face of the bar 9 and arranged to abut the adjacent face of the disk whereby to maintain the same in spaced relation from the shaft supporting bars. The collar fits over the hub of the disk and prevents dust and dirt from entering between the disk and the supporting bars 9. As a further precaution, a felt packing washor 18 is arranged within the end disk hub and the hub 11 of the bar 9.
A solid shaft member 17 extends through the tubular shaft 8, with the ends thereof supported in the hubs 11 and secured thereto by means of set screws 18 or the like.
The bore of the tubular shaft 8 is of an increased diameter over the solid shaft member 17 whereby to provide an oil reservoir enabling a sufficient lubricant to be maintained between the shaft at all times so as to facilitate the rotation of the tubular shaft 8 at each end upon the bushings 12.
The shaft 17 is tightly fitted within the bushings 12 at each end whereby to prevent the escape of the lubricant from the ends thereof.
It is apparent that the supporting bars 9 may be easily and quickly detached from the frame 5 so as to permit theremoval of any of the disks 13 from the shaft whenever it becomes necessary to repair or replace the same. Furthermore, such a construction on ables the parts to be manufactured and shipped in a dissembled relation thereby greatly reducing the shipping expenses for the same.
It is obvious that the invention is susceptible to various changes in the shape, size, and arrangement of parts, without departing from the spirit or scope of the invention as hereinafter claimed, and I accordingly claim all such forms of the device to which I am entitled.
The
I claim In a harrow frame, a horizontally disposed frame member, attaching plates arranged at each end thereof, a pair of vertically disposed bars attachable at their upper ends to said plates, said bars being formed of a pair of spacedly arranged members having hubs formed therein, a bushing carried in the hub of the innermost of said bar members, a tubular shaft rotatably supported at each end on the outer surface of said bushing a solid shaft extending through said hub and supported at each end within said bushing and extend ing through said tubular shaft in spaced relation therefrom whereby to form an oil reservoir between said shaft a plurality of disks each having a hub formed thereon and adapted to be arranged on said tubular shaft, means for securing the hubs of said disks to said tubular shaft for rotation therewith and flanged collars attached at the inner side of the shaft supporting'bars adapted to retain each of the end disks in spaced relation from said bars, and providing a protection against foreign matter entering the hub. i.
In testimony whereof I affix my signature.
