CHARLES L. FOWLE,
OF DOWAGIAC, MICHIGAN, ASSIGNOR TO DOWAGIAC DRILL COMPANY, OF DOWAGIAC, MICHIGAN.
DISK GRAIN-DRILL.
Specification of Letters Patent.
Patented Jan. ill, 1916.
Application filed October 16, 1912. Serial No. 726,076.
To all whom it may concern:
Be it known that I, CHARLES L. FowLE, a citizen of the United States, residing at Dowagiac, Michigan, have invented certain new and useful Improvements in Disk Grain-Drills, of which the following is a specification.
This invention relates to improvements in disk grain drills.
The main objects of this invention are: First, to provide in a disk grain drill, an improved scraper which is effective in clearing the disk even after the parts have become worn. Second, to provide in a disk grain drill, an improved arrangement of the disk, boot and scraper, whereby the disk is effectively cleaned and the likelihood of clogging reduced to a minimum. Third, to provide a structure having these advantages, which is simple and economical and very durable.
Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification.
The invention is clearly defined and pointed out in the claim.
A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:
Figure I is a side elevation of a structure embodying the features of my invention, the front end of the drag bar 1 being broken away. Fig. II is a detail sectional view on a line corresponding to line 22 of Fi I. showing the relation of the disk, toe of the boot and the scraper. Fig. III is a detail section on a line corresponding to the bro-ken lines 3-3 of Fig. I, showing the relation of the disk, toe of the boot and the scraper.
view of the scraper. Fig. V is a detail section on a line corresponding to line 55 of Fig. I, showing the arrangement of the scraper on the support. Fig. VI is a detail section on line 66 of Fig. I.
In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.
Referring to the drawing, I illustrate Fig. IV is an inside perspective' only one unit of a disk grain drill as that is sufficient for the illustration of my invention. In practice, these units are arranged in ranks or series and are secured to the frame of the drill by the draw bars 1.
The disk 2 is of the well-known concavoconvex type. i The boct 3 is arranged on the convex side of the disk. The lower end of the boot is curved inwardly and for wardly toward the side of the disk and is provided with a forwardly and inwardly projecting tapered toe 4:. The outer wall of the boot is curved C1 drawn into the toe at the lower end of the boct, as at 5. The discharge opening (5 is at the rear of the toe. See Fig. III. The boot is provided with a forwardly-projccting supporting arm 7 to which the draw bar 1 is secured by the bolts 8. The bearing for the disk is secured to this arm by means of the bolt-9.
The bearing is preferably that shown in the Saltsman Patent, #737,153, of August 25, 1903, adapted to a single disk, and as the details thereof form no part of my present invention, I do not illustrate or describe the same herein.
The support 7 is provided with a seat 10 for the scraper 11. This scraper is arranged in the seat and secured to the support by means of the bearing bolt The scraper is offset inwardly at 12 below the arm to bring it into coacting relation to the disk, its inner edge being curved or conformed to the disk. The offset 12 is twisted so that the blade of the scraper is supported at an angle to the plane of the disk. The scraper is arranged radially of the disk, its outer end being curved rearwardly in front of the toe of the boot and terminating below the same, but in a spaced relation thereto.
The toe of the boot lies above and to the rear of the scraper, and is protected thereby so that it is impossible for any object to become enga ed with the toe of the boot such as a stub or the like, as it will be cleflected by the scraper, or if the obstruction is unyielding, the scraper rides over the obstruction raising the disk with it. To pro vide means for the adjustment of the scraper, the scraper seat 10 is curved-and the scraper is correspondingly curved. The bolt hole in the scraper is slot-like so that the scraper may be adjusted on its seat to swing its blade to and from the disk. The scraper is of spring material. The outer iii) end of the scraper being free, a spring contact of the scraper with the disk remains even after the bearing forthe disk becomes worn, so that it swings away from the boot as the outer end of the scraper is in nowise inglysupported scraper, the disk must revolve perfectly true and without wabble, otherwise the scraper is ineffective, or if the rigid scraper is too close, the disk is locked, thereby causing the disk to slide instead of rotating as intended. The scraper may be renewed quickly and easily.
By shaping the boot as I have illustrated and described, there is little likelihood of clogging between the boot and disk. The toe of the boot is, as stated, guarded by the scraper, while there is sufficient space between the boot and the disk to permit the passage of soil and dbris that may pass over the scraper and between the boot and disk.
I have illustrated and described my improvements in detail in the form in which I haveembodied the same. While considerable variation in structural details is possible, I have not attempted to illustrate or describe the same herein as I believe the disclosure made will enable those skilled in the art to which this invention relates to embody the same as conditions may require.
Having thus described my invention, what I claim is new and desire to secure by Letters Patent is: I
In a disk drill, the combination with a disk,of a boot having a forwardly tapered inwardly curved toe, said boot being disposed on the convex side of the disk and provided with a forwardly projecting supporting arm, said arm having a curved scraper seat in its outer side, a bearing for said disk mounted on said arm, and a scraper mounted on said arm in sa'id'curved scraper seat whereby it may be adjusted relatlve to the disk, said scraper being curved downwardly and rearwardly in front of the toe of the boot with its outer end below and outof contact therewith.
In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
