摘要： A blade sharpener for manual use includes a base, and at least one sharpening device pivotally attached to the base. Each sharpening device has a channel for receiving a blade to be sharpened. A second pivotally attached device may be sharpening device or a guide. The two devices are pivotable independently of each other thereby accommodating any curvature of a blade to be sharpened as the blade sharpener is moved along the blade. A blade sharpener for use with a powered rotary tool includes a main body having a bore for receiving the powered rotary tool, and a channel for receiving a blade to be sharpened. A guide having a channel is pivotably attached to the main body to accommodate any curvature of a blade.

摘要： A portable blade sharpening apparatus is disclosed which can be used to sharpen blades while they remain attached to their machines. The blade sharpening apparatus is powered by an electric motor and includes a circular grinding stone which is angled on one side in order to match the angle of the blade to be sharpened. The angle of the grinding stone can be varied, depending upon the angle of the blade that is to be sharpened. The blade sharpening apparatus includes a guide bracket having fingers positioned to limit movement of the grinding stone relative to the blade being sharpened so as to prevent accidental contact between the blade and the drive shaft of the grinding stone.

摘要： The apparatus and method of this invention pertain to the sharpening of the blades of a reel mower having a framework about the reel. The apparatus comprises a belt having protuberances thereon, an assembly of pulleys and a drive motor for driving the belt and guiding the belt and protuberances to engage with the blades of the reel mower. The method of the invention is to use the apparatus of this invention and place it in a position so that, when the belt is revolved about the pulleys, the protuberances engage the blades of the reel mower thereby causing the reel to rotate in an opposite direction from the belt movement.

摘要： A knife abrasive apparatus for a rotary drum shaped cutter can grind the knife edge without causing it to be serrated. It has a rotary drum shaped cutter including a rotary drum and knives spacedly disposed on the outer periphery of the drum at a predetermined helical angle to a virtual surface which blade edges of the knives will draw. It also has an abrasive wheel to be used for grinding the edges. The wheel is declined at the rotary center axis with respect to a vertical plane to the rotary center axis of the cutter so that a composite vector composed of a peripheral velocity vector of the cutter and that of the wheel will become parallel to each of the edges in the longitudinal direction of each of the knives. The velocity of rotation of the cutter and the wheel is controlled to maintain the ratio of the peripheral velocity of the former and the latter constant. The abrasive wheel is supported by a movable supporting member.

摘要： The cutting cylinder of a forage harvester has helically oriented knives which may be sharpened by shifting a spinning grinding stone back and forth across the housing for the cylinder in parallel relationship with the axis of rotation of the cylinder. Opposed sets of roller guides which move with the stone in its straight line reciprocation trap the blade being sharpened and force the cylinder to rotate to such an extent and in such a direction as to continuously maintain the bevel on the knife engaged with the stone, thereby compensating for the helical orientation of the knife. One set of roller guides rides along the normally leading edge of the knife being sharpened, while the other set of opposed roller guides rides along the outer surface of the knife being sharpened.

摘要： A forage harvester having a rotatable cutter head co-acting with a shear bar is provided with means to rotate the cutter head stepwise for inspection of the knives of the cutter head without manually engaging the same. The means for advancing the cutter head also provide tension applied against the knives of the cutter head incident to the same being ground by a rotatable grinding wheel to re-bevel the surfaces of the knives adjacent the cutting edges thereof for purposes of producing effective operating engagement of said grinding wheel with said knives during such re-bevelling of the same.

摘要： An apparatus for controlling both the operation of a cutting reel and the grinding mechanism of a forage harvester having a transmission member which supplies power from the drive shaft to a coupling assembly. The coupling assembly is operably associated with the drive means of both the cutting reel and the grinding mechanism to selectively drive the cutting reel in a forward direction while the grinding mechanism is disengaged from the drive shaft, or in a rearward direction while simultaneously driving the grinding mechanism, or to drive the grinding mechanism while the cutting reel is completely disengaged from the drive shaft.

摘要： The beveled edges of the spiral blades of a reel cutter are sharpened by advancing a rotatable grinder therealong as the reel is advanced at the same time, all through use of but a single, crank operated drive shaft. Power is transmitted from the crank to a shiftable support for the grinder through a pair of operably interconnected chain and sprocket wheel units. Power is also transmitted from the crank to the reel through a worm and worm gear arrangement, a pair of levers, an indexing assembly on the driven shaft of the reel and an adjustable link between the levers.
