CLEANING ATTACHMENT FOR DISK IMPLEMENTS.
SPECIFICATION forming part of Letters Patent No. 715,910, dated December 16, 1902.
Application filed May 29,1902. Serial No. 109,534. (No model.)
T0 on whom it may concern:
Be it known that 1, WILLIAM L. WALTON, a citizen of the United States, residing at Neche, in the county of Pembina and State of North Dakota, have invented a new and useful Cleaning Attachment for Disk Implements, of which the following is a specification.
This invention relates to that class of seeddrills in which pairs of disks mounted revolubly at angles to each other are employed for the purpose of opening the furrows to receive the seed.
My invention has for its object to provide a means for cleaning the said disks which shall be simple, easily applied, and efficient in operation. 7
With these ends in View my invention specifically consists in the improved construction and arrangement of such cleaning device or attachment which will be hereinafter fully described, and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a side View showing a drill-tube and the portion of a frame of a grain-drill carrying the revolving disks and showing my improved cleaning device attached in position for op- Fig. 2 is a top plan view of the same. Fig. 3 is a perspective view showing the cleaner detached. Fig. 4 is a perspective view showing a modified construction of the cleaner. Fig. 5 is a plan view showing my invention arranged in connection with a pivotal washer which it may be found desirable sometimes to use. Fig. 6 is a perspective view showing the pivotal washer detached. Fig. 7 is an end or edge view of the cleaner shown in perspective in Fig. 3.
Corresponding parts in the several figures are indicated by like characters of reference.
My improved cleaning attachment in its simplest form is composed of a piece of steel Wire 1, at one end of which is formed an eye 2 and the outer end of which is flattened to form a blade 3, which is hardened or tempered and ground to a cutting edge 4, which latter is disposed oppositely to the eye 2. The wire 1 is bent at the intersection of the blade 3 with the unflattened portion, which forms a shank 5, which latter is possessed of some degree of resiliency.
6 designates a portion of the frame of the seed-drill, and 7 is the drill-tube, to which and in rear of which are formed lugs 8 8, through which passes a transverse bolt 9, upon the ends of which my improved cleaning devices are mounted, as shown in Fig. 2, the shanks 5 being extended downwardly and rearwardly over the rear edge of the segmental shield 10, which constitutes a portion of the frame, and the blades 3 being disposed upon the outer sides of the rotary cutter-disks 11. The arrangement of the blades 3 with relation to the cutter-disks will be readily understood by reference to Figs. 1 and 2 of the drawings,
from which it will be seen that the blades, with their cutting edge facing in a rearward direction, are extended downwardly and forwardly from the shanks 5, the points of said blades terminating at a point which in practice should be only about two inches from the periphery of the cutting-disk 11. When the latter rotates, it will thus be seen that the dirt'adhering thereto will be removed by a long sweeping motion, which renders such removal much easier and much more effective than if the cutting-blades were arranged radially, or approximately so, with relation to the disks.
It will be seen that in order to provide for the attachment of the cleaning devices in such a manner that the blades 3 shall not only have the requisite slope with relation to the disks 11, (which is brought about by bending the wire or piece of material of which the device is formed to form the angle 14, as shownclearly in Figs. 1, 4, and 5 of the drawings,) but also to cause it to liewith its edge fiat against the face of the disk, it becomes necessary to bend the shank portion 5 anglingly to the plane occupied by the edge of the blade 3, as will be understood by reference to Fig. 7 of the drawings, by reference to which it will appear that the shank portion 5, which has already been bent at an angle to the blade 3, is further bent out of the plane of said plate. Moreover, the eye 2,
which is formed at the end of the shank 5, is twisted in such a manner that its bearing or contact points 15 15 on opposite sides of the axis thereof shall be included in a line drawn through the axis of said eye and through the center of the cutting edge 4 of the cleaning device. This construction is extremely important, because without it if the nuts were tightened upon the bolt upon which the cleaning devices are mounted an unequal pressure upon the blades of the same would be the result, one end of the blade being thus left in less rigid contact with the adjacent disk 11 than the other end of said blade, fine roots and other obstructions would gradually become wedged under the looser end, and the successful operation of the device thus be interfered with.
In Fig. 4 of the drawings I have shown a modified construction of my improved cleaner, which consists in attaching to the flattened portion 3 a separate tempered blade 17, having the cutting edge. This construction may sometimes be found preferable. In other respects the construction of the cleaner is identical with that already described.
I have found that sometimes the play of the disks 11 in their bearings will cause a somewhat uneven pressure upon the blade and cutting edge of my improved cleaner or between said blade and cutting edge and the face of the disk. To obviate the difficulty caused thereby, I have devised the pivotal washer illustrated in Figs. 5 and 6 of the drawings, and which consists of a metallic washer the two sides of which are connected by bent portions or bridge-pieces 20, the said opposite sides being designated 21. Each side of the washer is provided with a transverse rib 22, projccting outwardly and forming the bearings upon which the washer may have a pivotal or swinging movement with relation to the adjacent clamping or tightening parts. \Vhen a washer of this construction is adjusted upon the connecting-bolt 9, with its sides 21 engaging opposite sides of the eye 2 of the cleaning device, the latter will be permitted a limited pivotal movement, whereby it is enabled to adjust itself to slight changes in the position of the disks 11, resulting from reasons that have been above referred to.
From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood.
It will be observed that the points of my improved cleaners are extended well in a downward direction. The removal of the dirt adhering to the disk thus begins soon after the disk leaves the ground in its progressive rotation and much of the danger of clogging is avoided. The dirt adhering to the disk is loosened as soon as it comes in contact with the point of the cutter and will be gradually and easily detached, the weight of the dirt causing it to drop behind the disk in a position where the operative parts of the device will not be interfered with. The provision which I have made for maintaining an even pressure of the edge of the cleaner upon the face of the disk makes it practically impossible for particles of roots and other obstructions to become wedged in the device and in terferin g with its operation. All obstructions will eventually slide off at the rear edge of the disk. Whenever it shall be desired not to use the cleaners, the blades may be simply lifted off from contact with the disks, where they are normally held with a considerable degree of tension. When thus released, the said cleaners may be permitted to swing freely behind and between the disks, remaining supported loosely upon the bolts which engage the eyes of said cleaners. It is evident that when the cleaners are thus disposed there will be a considerable reduction in the power required to propel the machine, inasmuch as the frictional contact of said cleaners with the disks is avoided. It is obvious that the cleaners may be restored to operative position as easily and as swiftly as they may be released. By my improved cleaners the adhering dirt is removed before it reaches the top of the frame. Hence there is no danger of its clogging or filling in between the top of the frame and the disks, and the power required to lift the adhering dirt to this point is saved.
Other advantages might be mentioned; but they will be readilyapparent to anyone skilled in the art to which my invention appertains and need not be further enumerated.
I desire to state that while I have described the preferred form or forms of my invention I do not consider myself as limited as regards details, but reserve the privilege of making any such further changes,alterations,or modifications as maysuggest themselves in practice and which may be resorted to without departing from the spirit of my invention.
Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. A disk-cleaner consisting of a blade, a shank bent at an angle to said blade and an eye formed upon said shank and bent out of the plane of the latter, substantially as set forth.
2. A disk-cleaner consisting of a blade, a shank bent at an angle thereto and further bent so as to lie in a different plane from the blade and its cutting edge, and an eye formed upon said shank and bent out of the plane of the latter, substantially as set forth.
