Specification of Letters Patent.
Patented Nov. "Z, 1916.
Original application filed May 27, 1915, Serial No. 30,810. Divided and this application filed December 28, 1915. Serial No. 69,031.
To all fzozfcm t may concern Be it known that I, HARRISON B. BozAnD, a citizen of the United States, and a resident of La Crosse, county of La Crosse, and State of ldlisconsin, have invented an Improvement in Scrapers for Seeding-Machines, and do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to Scrapers for the disks of seeding machines, and my object is to provide a construction which can be cheaply manufactured, but which will produce a strong and efhcient device.
In the annexed drawings z-Figure 1 is a side elevation of a double furrow opener, embodying my invention; Fig. 2 is a detail view showing, in section, the scraper-arm pivoting means.
Referring to the drawings, 10 designates the drag-bar attaching frame having a vertical stem upon which is rotatively mounted the disk 12. Projecting from the side of the boot shank 13, is a horizontal boss 14, to which is pivotally connected the scraper arm 15, which at its lower end carries the scraper blade 16. The arm 15 is formed of heavy spring wire which is coiled to provide intermediate the ends of the arm a coil 17 which consists of several turns to form the arm pivot. Passing through the coil which is snugly fitted thereon, is a sleeve or bushing 18, and said sleeve also passes through the boss 14. Passing through the sleeve is a bolt 19 having on one end a nut, 20, and at its other end a head 21 between which and the adjacent end of the sleeve is a washer 22 that overlaps the adjacent end of the coil. when the bolt is secured in position the sleeve end will project slightly beyond the outer side of the coil so that friction-producing contact of washer and coil will be prevented and thus free rocking movement of scraper arm upon the blade will be permitted.
The sleeve is of such length thatl The coil formed on the scraper arm is to provide the pivotal bearing and my object in forming the pivot by the coil is to enable the arm to be made of wire upon a spring making machine and thus it can be manufactured readily and cheaply. As usual, the scraper arm is extended above the coil and its upper end is engaged by a coil spring 23, that lies between the ring guard of the boot and which serves yieldingly to press and hold the scraper blade in contact with the side of the disk. This action of the spring 23 is, or may be, supplemented by such springiness or elasticity of the scraper arm itself as may be due to its being constructed of wire, and with the coil to form its pivot.
As will be evident, my scraper arm is applicable to single as well as double disk furrow openers, and, therefore, I do not limit myself to its employment with either.
This application is a division of my application No. 30,810, filed May 27, 1915.
Having thus described my invention what I claim is 1. The combination of a boot frame, a disk mounted thereon, av scraper blade, an arm carrying said blade and formed of wire that is wound into a coil at a point between the ends of the arm, a sleeve passing through said coil on which it may rock and means connecting said sleeve with the boot frame.
2. The combination of a boot frame, a disk mounted thereon, a scraper blade, an arm carrying said blade and formed of wire wound into a coil at a point between its ends, a sleeve passing through said coil, a boss projecting from the side of the boot frame through which said sleeve passes and affastening bolt passing through the sleeve and confining the coil on the sleeve while allowing it to rock thereon.
In testimony that I claim the foregoing I have hereunto set my hand.
HARRISON B. BOZARD.
