A.\ C. LINDGREN FLEXIBLE DISK PLOW SCRAPER Patented Nov. 2%, 1923.
i Lesa o ALEXUS C. LINDGREN, F EVANSTON, ILLINOIS, ASSIGNOR TO INTERNATIONAL HAB- VESTER COMPANY, A CORPORATION OF NE JERSEY.
FLEXIBLE DISK-PLO; SORAPER.
Application filed May 14.
,5 and State of Illinois, have invented certain new and useful Improvements in Flexible Disk-Plow Scrapers, of which the followingis a full, clear, and exact specification.
This invention relatesto improved scraper i0 construction for diskplows and the objects of the invention are to provide a scraper of simple and durable construction combined with a plow disk in such a manner that the soil being turned will press against its blade w in a way tending to keep the blade edge in contact with the disk face and prevent lodgment of trash under the edge of the scraper blade. Also, to support the scraper so that it will be capable of practically universal adjustment and so that the blade will be resiliently held, in position and capable of following any wobble of the disk or unevenness in its surface.
These objects are accomplished by constructing the scraper with a novel form of inverted U-shaped shank, one arm of which is extended as a leaf spring which carries the scraper blade while the other arm is adjustably received in a support clamp overhanging the face of the disk. This construction places the blade and its supporting arm well out over the face of the disk and permits the blade to be presented to the disk at the angle at which most efiicient operation of the scrap- 5 er is obtained. I
With the above main objects in view my invention consists of the organization, details of construction, parts and their equivalents hereinafter described and defined in the claims.
Having reference to the drawings:
Figure 1 is a perspective view of a scraper and disk embodying my invention.
Fig. 2 is a side view on a reduced scale showing the supports for the scraper and 5fl tion comprises the revolving plow disk 5,
supported on the bearing bracket 6, attached to the beam and frame of the plow in a well known manner. "Bolted or otherwise secured to the frame of the plow as at 7 is an angular arm 8 which has a horizontal por- 1920. Serial N0. 381,438.
tion entending over and beyond the edge of the d sk. This horizontal portion has the arm 9 of the scraper supporting clamp bolted thereto, which clamp is composed of complemental members 10 and 11.
with a slot 12 as seen in Fig. 3, while the member 11 is convex and provided with a slot 13 at right angles to slot 12. The engaging faces of the members 10 and 11 are pref- The member lO'is concave and is provided erably corrugated as shown in Fig. 3; An
eye bolt 1 1 passes through the crossed slots 12 and 13 and has one arm of the shank 15 positioned in its eye. This shank also engages in a pair of seats or notches 11 formed on the clamp member 11 and is drawn into position therein by the nut 16 on eyebolt 14 and securely held in any position of adjustment desired.
The construction just described permits adj ustment of the clamp members on each other as well as vertical adjustment of the shank in the clamp.
The shank member 15 is of inverted U- shaped form as clearly shown in Figs. 1 and 2 and has a long and short arm, the longer one being attached to the clamp while the shorter one has riveted or otherwise fastened thereto, as at 17, a flat resilient member 18 which forms a continuation of said arm and which in turn has fastened to it the scraper blade 19 which has its lower edge shaped to conform to the concavity of the disk. The short arm of the ti-shaped shank permits employment of a resilient blade-arm of the length necessary for efficient action and the manner in which the longer arm is held in the clamp places the shorter scraper carrying arm well out over the face of the disk with the resilient member 18 and blade 19 positioned at such an angle to the disk that the furrow slice presses on the blade and keeps its edge in contact with the disk. The movement of the clamp members 10, 11 on each other affords the angular adjustments required and adjustment of the longer shank arm in eye 14 affords vertical and lateral ad j ustment, all the adjustments becoming possible upon loosening of the nut 16. The scraper blade is preferably placed with its edge about half way down on the disk and slightly spaced from its surface, the pres sure of the soil forcing it against the disk face.
The construction above described provides a scraper sufiiciently resilient to be held in light contact with the disk face by pressure of the soil during operation, preventing lodgment of trash and one that has practically a universal range of adjustment and is so constructed that the scraper and shank can be moved to desired position by loosening of only one bolt and without interference from adjacent parts.
Having described the construction comprisingmy invention, what I claim as new 1s:
1. The combination of a disk, a support overhanging the face of the disk, a clamp on the support, a U-shaped scraper-shank having one arm adjustably carried by the clamp, a flexible member forming an extension of the other arm and a scraping element on the flexible member with its edge adjacent the disk.
2. A disk scraper consisting of a rigid U- shaped member with substantially parallel arms one of which is adapted to be held in a support and the other arm provided with an extension comprising a fiat spring member carrying a scraper.
3. The combination with a concave plow disk supported on an inclined bearing, of a scraper supporting arm extending horizontally over the disk, a universally adjustable clamp secured to saidarm, a scraper shank formed with parallel depending rigid arms, one of which is vertically adjustable in said clamp, a spring forming an extension of the other arm, and a scraper blade secured to sainllI spring in cooperative relation to the dis a V i In testimony whereof aflix my signature.
