SCRAPER FOR DISK HARROWS- Specification of Letters Patent.
Patentedfiuly 31,1906.
Application filed October 8, 1904. Serial No. 227,698
To wZZ whom it may concern:
Be it known that we, SAMUEL V. KE NEDY and CHARLEs S. SHARP, citizens of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented a certain new and useful Improvement in Scrapers for Disk Harrows, of which the following is a specification.
Our invention relates to that class of scrapers for disk harrows in which the scrapers are movable toward or from the disks and the object of our invention is to simplify and perfect the construction of such scrapers and to lessen the cost of their manufacture.
Referring to the drawings forming part of this specification, Figure 1 is a rear view of a gang of disks, showing our improved scrapers attached. Fig. 2 is an end elevation of the same, omitting the lever; and Fig. 3 is an enlarged detail view inpart section.
The disks A are journaled upon anaxle B and s aced by spools C in the usual manner. Stan ards D connect the disk gang with the gang-beam E, which has secured to it supports F F, slotted at their outer ends to carry the scraper-bar G, the slots being sufficiently large to permit a longitudinal movement of the scraper-bar.
Brackets H are pivotally mounted upon the scraper-bar G and have downwardly-projecting arms I, to which the scraper-blades A are rigidly secured in any suitable manner. Sockets J areformed in the brackets H and are slotted at the top to admit the lower edge of the scraper-bar Gr. Coiled springs g are within the sockets J and contact with the bottoms thereof and with the scraper-bar Gr, beirg retained in the sockets by the scraperbar,'so that while there is a certain. amount of resil ency in the scraper-blades A, a more perfect and yielding contact with the disks is insured. Lips or projections c are formed upon the brackets H and by contact with the scraper-bar G limit the movement of the brackets and scrapers toward the disks.
Pivoted upon the scraper-bar at a is a crank-arm (1,, having a lever b bolted to it,
' and a link I), hooked in an eye a and adjustably connected to the support F, so that it is apparent that when the lever b and connectposition against the dis s and are so held by reason of the fact that the link I) is thrown below the centerof-the pivotal point of thecrank-arm a. Thescrapers are moved out of engagement with the disks by a reverse movement of the lever, lines, Fig. 1.
Having thus described our lnvention, what We claim, and desire to secure by Letters Patent is 1 The combination With the disks, of a scraper-bar, scraper-carrying brackets p voted thereon, sockets in the brackets containing springs in contact with the scraper-bar, and slots in said brackets with which the scraper-bar engages. I
2. In a scraper for disk harrows, the com bination of a scraper-bar, a pivoted bracket thereon carrying a scraper-blade, a socket 1n the bracket, a spring therein in contact with the scraper-bar on one side of the brackets pivot, and a lip or projection on the bracket to engage with the scraper-bar on the other side of the pivot and limit the forward moveas shown in dotted ment of the bracket by the action of the spring, the socket having a slot engaged by the scraper-bar.
3. In a scraper for disk harrows, the combination of a scraper-bar, a bracket pivoted thereon and carrying a scraper-blade, a socket in the bracket containing a sprlng, and a slot in the socket with which thescraper- .bar engages to hold the spring in the socket.
4:. In a scraper for disk harrows, the combination of a scraper-bar consisting'of arelatively thin flat bar set vertically edgewlse, a bracket pivoted to one side of the bar and carrying a scraper-blade, a socket in the bracket on one side of its pivot, a spring therein reacting against the under side of the scraper-bar, a lip or projection on the bracket on theotherside of its pivot to l1m1t the forward movement of the bracket, and a slot in the socket in which the scraper-bar enga es, whereby the bracket is braced and gui e in its movements.
In testimony whereof we hereunto set our hands, this 21st day of September, 1904., in the presence of two attesting witnesses.
SAMUEL V. KENNEDY. CHARLES S. SHARP.
