CLEANING AND POLISHING PAD FOR DISKS Filed March 5, 1955 INVENTOR. William Ellioff Patented June 30, 1936 CLEANING AND POLISHING PAD FOR DISKS William Elliott, Beatrice, Nebn, assignor to PATENT OFFICE Dempster Mill Manufacturing Company, Beatrice, Nebn, a corporation of Nebraska Application March 5, 1935, Serial No. 9,444
s'oiaims. (01. 91-223) My invention relates to disk polishers, its object being the provision of a polisher having a squeegee function on thedisk. Q
One of the serious difliculties encountered by farmers in the use of soil working tools is the difllculty of making them scour. A clayey soil or a black loam and many other soils contain colloids which adhere tenaciouslyto the polished surface of steel and they almost immediately begin to set up a chemical action which eventually destroys the polish and which permits the accumulationof soft soil on the earth working. .tool to destroy its effectiveness.
My main object is the provision of a tool which will in a large measure prevent the formation of the colloidal film and which will remove the traces of such film as fast as the film is formed.
Having in view these objects and others which will be'pointed out in the following description, I will now refer to the drawing, in which Figure 1 is an elevational view of a disk and the polishing tool, the disk being-viewed in edge elevation and with a portion broken away.
Figure 2 is a view similar to Figure 1 but show ing a somewhat different form of disk.
Figure 3 is another elevational view showing the tool with still another form of disk.
' Figure 4 is a view in elevation showing the disk of Figure 1 when looking toward the inside of the disk.
Figure 5 is an elevatlonal viewof the polishing tool shown in Figures 1 and 4.
Figure 6 is another view in elevation of the same toolas seen when looking at the edge of the squeegee and its clamp.
Figure 7 is a plan view of the squeegee alone.
Figure 8 is a view similar to Figure 5 but showing the tool in the form whichis used on the disk shown in Figure 2. I
The squeegee I shown in Figure 1 is preferably made from belting which consists of a multiple ply fabric which is impregnated with or imbedded in rubber or a rubber composition. It is shaped to conform to the shape of the disk, the form shown at ill being the form employed in the disk shown in Figures 1 and,4 in which the 1 disk has a central portion Ii in" the form of a circular plane' and a peripheral portion l2 in frusto-conical form. This necessitates that the squeegee l0 must have a cutaway comer to accommodate itself, to the portions II and I 2' of the disk. It is desirable that the squeegee be of such length and shape and position that it will reach all parts of the disk from the center to the circumference and for this reason the position should be radial but it may be non-radialas shown in Figure 4 if the central portion of the disk is not to be polished. This squeegee l0 must be mounted so that its operative edge will be in firm contact with the disk as most clearly shown in Figure 3.
For the support of the squeegee Ill I provide two clamping plates l3 and l4,' thcse two plates being held together in clamping relation by means of the bolts IS. The inside plate i3 is identical in form with the outside plate id but the bolt holes are staggered to expose the operative 'edge of the squeegee. The squeegee lllis provided with two slots l6 for the reception of the bolts l so that the squeegee may be adjusted to bring its exposed edge flush with the operative edge of the plate M. A rod I1 is bent and flattened at its lower end for attachment to the plate l3 as by bolting or riveting or welding. This rod I1 is adapted for connection to a fixed part of the implement in such position that only the edge of the squeegee ill will contact with the disk.
It is obvious that the operative edge of the squeegee as well as the corresponding edgesof the two plates must conform to the shape of the disk. The disk It shown in Figure 2 is curved throughout andv it is therefore necessary that the squeegee Ina be curved similarly to the curvature of the disk was shown in Figure 8. In disks of the forms having plane surfaces the operative edge of squeegee 10b is in the form of a straight line as shown in Figure 3.
Regardless of the form of the disk the squeegee must, be so positioned that its edge portion will bear against the disk to prevent the formation of the colloidal filmand to remove the traces of film as fast as they are formed. The rotation of the disk in the soil will bring all parts of the surface of the disk. into contact with the squeegee which thus acts continuously and reaches every point on the surface of the disk at each revolution of the disk. The continuous action of this squeegee tends to develop a high polish on the disk. which of itself counteracts any possibility of the adhesion of any film or foreign material of any nature. New earth working disks require considerable time in order to secure the proper earth polish; This squeegee by which makes for the most efllcient working sur- I face on a disk which it is possible toproduce;
The present device is not to be confused with the scrapers in common use. Such scrapers are designed for the purpose of removing soft soil from the earth working tool but they cannot function to prevent the adhesion of the colloidal film to the steel surface. The difficulty is that these scrapers cannot attack the colloidal film which forms on the po shed steel surface and as long as the colloidal film is present the adhesion of soft soil cannot be prevented. These scrapers are usually formedgof metal such aslsteel which does not have themroper contact with the steel of the earth working tool to attack the very thin col-v loidal film. Thus scrapers are usually made of a material which wears down rapidly due to abrasion and in this respect also my squeegee'difiers of the pad has a triangular form in cross section.
This accumulated soil becomes compacted and materially assists in the polishing of the soil working tool. I
The squeegee must be relatively soft and relatively pliable and relatively compressible since the squeegee action depends very largely on these factors. For example, steel against steel could not be made to form a continuous line of contact. On the other hand, softness or compressibility in too high a degree relative to steel would be fatal to the squeegee function. It is obvious that a few materials other than belting would fall between these limits to perform the function of. a squeegee operating against the smooth surface of a rotary soil working disk.
Having thus described my invention in such full, clear, and exact terms that its construction and operation will be readily understood by others skilled in the art to which it pertains, what I' claim as new and desire to secure by Letters Patent of the United States is: 1
