HARRY C. EGWE, O'l QWATONNA, MINNESOTA, ASSIGNOR TO OVA'IONNA MANUFAC- TURING COMPANY, OF QVATQNNA, MINNESOTA, A CGRYPORATION.
GOILEBIN'ED DISK DRILL AND HARROVT.
To all 10. mm it may concern:
Be it known that I, HARRY C. Hows, of Owatonna, Steele county, Minnesota, have invented certain new and useful Improvements in *Co-mbined Dis-k Drills and Harrows, of which the following is a specification.
My invention relates particularly to single disk drills, and the object of the invention is to provide a drill which can be easily and quickly adapted for use eitheras a drill or as a d-islr-harrow.
A further object is to arrange the connections with the disk to avoid as far as possible all danger of clogging.
Other objects of the invention will appear from the following detail-ed description.
The invention consists generally in a bar or other suitable connecting means extend ing from the boot over the disk to a point on the drag-bar in front of the disk.
Further, the invention consists in mounting the disk on the drag-bar so that its angle with respect to the line of draft can be changed, and making the boot detachable from the drag-bar to adapt the drill for use as a harrow.
Further, the invention consists in various constructions and combinations, all as hereinafter described and particularly pointed out in the claim.
In the accompanying drawings, forming part of this specification, Figure l is a side elevation of a portion of a disk drill embodying my invention. Fig. 2 is a top view of the same. Fig. 3 is a view similar to Fig. 1, the boot being shown removably connected to the drag-bar to adapt the machine for use when desired as a disk harrow. Fig. 4 is a view similar to Fig. 3 showing the removable or adjustable boot with the scraper omitted and with another form of angular adjusting means at the axis of the disk. Fig. 5 is a sectional view through the hub of the disk shown in Fig. at. Fig. 6 is a sectional view showing in detail the disk adjusting means of Fig. 3. Figs. 7 and 8 are detail sectional views of the end of the drag bar and the hub of Fig. 6.
In the drawing, 2 represents a drag-bar of suitable construction and 3 a concavo convex disk. A hub 4 is provided on the concave side of said disk and held in place thereon by a casing or housing 5. The hub Specification of? Letters Patent.
Application filed November 27., 1906.
Patented Oct. '7, 1913.. Serial No. 345,367.
projects through an opening 6 in said casing and has a beveled end 7 that contacts with a corresponding beveled surface 8 on the drag bar. A hole 9 is provided in the drag bar to receive a locking bolt 10 that fits into a threaded opening 11 in the hub and secures the drag bar and hub together. Lugs 11" are provided on the hub adapted to fit into sockets Il provided in the dragbar on each side of the hole 9. These lugs and sockets allow two adjustments of the disk, one as indicated by full lines Fig. G and the other by dotted lines in the same figure.
lin Fig; 5: I' have shown a modification which consists in providing a hub 12' having 7 a square outer end acap 1 3 fittingt-hereon, the outer face of the cap being provided with a rib letthat is adapted to enter any v one. of a series of grooves 15 in the surface 1 of the drag-bar. The drag-bar, cap and hub are secured together by a bolt 16 which when loosened will allow the disk to be swung toward or from the drag-bar, and its angle with respect thereto changed. The drag-bar has a slot 17 through which the bolt 16 extends to permit the oscillation of the disk. Either of these adjustments may be used and the angle of the disk changed with respect to the direction of movement and the machine adapted for use either as a drill or a disk harrow.
In the rear of the disk, Fig. l, is a boot 18 having a scraper 19 on its lower end that is adjustable around the vertical axis of the boot, said scraper being arranged to sweep the convex surface of the disk and keep it clean. Instead of connecting the boot to the drag-bar at or near the center of the disk by means of the forwardly and downwardly extending arm usually employed for this purpose, I provide a bar 20 secured to the boot near its upper end and extending forwardly therefrom above the disk and secured at its forward end to the drag bar. This bar will be entirely above the disk as shown in Fig. l and will not catch refuse material as the machine is drawn over the field and cause clogging, will leave the convex side of the disk entirely unobstructed and only the connection of the drag-bar to the disk on the concave side. The bars extending over the disks act as a guard and prevent the disks in passing over rough ground from being thrown up against the machine axle and they also prevent the boots from striking the feed cups. The independent connection of the boot with the drag-bar also makes it easier to mount and adjust the disks in their bearings.
In Fig. 3 I have shown a modification of the connection between the boot and dragbar which consists in providing a curved bar 21 extending forwardly above the disk as described with reference to the bar 20, and having a slot 22 in its forward end to receive a bolt 23 in a casting 24 that is secured to the drag-bar in front of the disk. One of the bolts 25 for securing the casting to the drag-bar preferably passes through the slot in the bar 21 and by loosening this bolt and the bolt 23 the bar may be moved lengthwise and the boot tilted forward or backward as desired. Such adjustment of the boot will permit its lower or discharge end to be swung in toward the disk for the purpose of depositing the seed in the furrow and nearer the base or lower edge of the disk. In other respects the bar 21 will have the same functions as the bar 20 and by making it removable from the drag-bar all the boots can be taken oil the machine whenever desired and the drill used as a harrow, the disks being adjusted for the desired width of furrow. The bars extending over the disks form attachments for the boots with the drag-bars and provide a simple and economical construction and the boots being located in the rear of the disks, the grain will drop directly into the furrow that is opened by the disks. The scraper shown in Fig. 3 may be used or omitted, as desired. 7
I claim as my invention A device of the character described comprising a drag-bar, a disk rotatably mounted on the rear end of the drag-bar, a boot at the rear of the disk, and a curved bar connecting the boot and drag-bar and having an adjustable connection with the dragbar at the front of the disk to permita vertical adjustment of the boot in the arc of a circle, substantially as described.
In witness whereof, I have hereunto set my hand this 21st day of October 1906.
