DISK-SORAPING MECHANISM.

Specification of Letters Patent.

Patented. Nov. 20, 1906.

Original application filed. January 30, 1 90 6, Serial No. 298,6 8 9. Divided and this application filed May 18,1906 Serial No. 31 7,5 '79.

To all whom it may concern.-

Beit known that I, IRA JAMES KAAR, a resident of Havelock, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Disk-Scraping Mechanism and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in disk-scraping mechanism, this application being a division of application filedJanuary 30, 1906, and designated by Serial No. 298,689, Patent No. 825,466, the object of the invention being to provide improved mounting and operating mechanism for scrapers to clean two or more pairs of disks; and the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described, and pointed out in the claims.

The accompanying drawing is a view in front elevation illustrating my improvements.

1 represents a section of frame serving as a support for a notched segment 2, and a vertica ever 3 is pivoted between its ends to the segment 2 and provided with a detent 4 to engage the segment and lock the lever at any adjustment.

5 and 6 represent parallel longitudinallymovable rods, the former connected by a link 7 with lever 3 above the pivotal point of the latter and the rod 6 connected by a link 8 with the lower end of lever 3. To the ends of these rods 5 and 6 arms 9 are loosely secured and carry scrapers 10 at their lower ends to engage the concave faces of disks 11 to clean them, and it will be seen that by moving the lever 3 all of the scrapers will be simultaneously moved toward or away from all of the disks, as the case may be.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but

consider myself at liberty to make such slight changes and alterations as fairly fall within the s irit and scope of my invention.

Having fufiy described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with supporting means, of two longitudinally-movable rods mounted therein side by side, a lever mounted on the support between the ends of said rods, connections between the lever and rods for moving the latter longitudinally in opposite directions, scrapers and rigid connections between said rods and scrapers.

, 2. The combination with supporting means and two longitudinally-movable rods mounted therein side by side and extending in both directions from said support, scrapers having rigid connection with the respective ends of each rod, a lever pivoted between its ends to said support, and links connecting said rods with the lever at respective sides of the fulcrum of the latter.

3. The combination with a support and two longitudinally-movable rods mounted therein side by side, each of said rods projecting beyond the adjacent end of-the other rod, of a scraper carried by and movable with each of said rods and means for moving said rods simultaneously in reverse directions.

4. The combination withsupportingmeans and two longitudinally-movable rods mounted therein side by side, each rod projecting beyond the adjacent end of the other rod, of scrapers carried by the respective ends of said rods, a vertically-disposed lever pivoted between its ends to said su port, a link connecting one of said rods wit h the lever below the pivotal support of the latter and a link connecting the other rod with the lever above the pivotal support of the latter.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
