Abstract: A dressing device for sharpening or conditioning of a blade or the like includes one or more disk pairs each having a pair of disks respectively presenting a plurality of ribs. The disks are oriented in face-to-face relationship with the ribs thereof in meshed, intercalated relationship to thereby create circumferential dressing openings. The ribs are configured to create sharpened edge on a knife blade or the like.

Abstract: A rotary trimmer includes a first trimming element having a first knife and a second trimming element having a second knife that operates jointly with the first knife. In order to sharpen one knife, the other knife is removed and is replaced with a sharpening disk. The sharpening disk or the knife to be sharpened is advanced during a sharpening operation.

Abstract: A preferred embodiment of a guide boot for a fiber-optic cable mechanically coupled to a connector comprises a mating portion having an interior surface defining a passage for receiving a portion of the connector and the fiber-optic cable, and a plurality of ribs formed on the interior surface and extending along at least a portion of a length of the mating portion. A preferred embodiment of a guide boot also comprises a body portion adjoining the mating portion and having an interior surface that defines a passage for receiving the fiber-optic cable. The interior surface of the body portion is curved so that the body portion bends the fiber-optic cable.

Abstract: A sharpening apparatus with substantially rigid sharpening wheels disposed substantially fixedly on a rotatable drive shaft. An edge of a blade inserted in a slot in the apparatus comes into contact with a sharpening surface on a sharpening wheel. A sliding block associated with that sharpening surface slidably yields to accommodate the inserted blade and applies a force on the blade towards the sharpening surface. The user may selectively adjust force on the blade to achieve more or less sharpening of the edge of the blade. The plurality of sharpening surfaces can offer different levels or degrees of sharpening.

Abstract: A foldable hand sharpening tool is disclosed, having an elongate body/handle with a first sharpening member pivotally mounted at one end which folds into the body when not used, and at the other end having a “V” shaped sharpening slot formed by opposing sharpening members with pivotable elongate guide members which pivot into place to retain the blade in alignment in the “V” slot during sharpening and fold into the body when not used.

Abstract: A sheet metal edging file comprises a frame with a base and two side arms which extend upwardly. The side arms are formed in a generally planar configuration with an inner surface, an outer surface, parallel short end edges and parallel long side edges. The side arms also have an upper region and a lower region, with one short side of each side arm being contiguous with the upper surface of the base. The upper region of each side arm also includes a centrally located aperture extending therethrough. The plane of the side arms are angled at an acute angle with respect to the axis of the base. Two file wheels are formed in a planar, generally circular configuration with a centrally located circular aperture extending therethrough. Each wheel has an inner surface and an outer surface and includes a plurality of blades on its inner surface. The blades extend radially outward from the central aperture to a location proximate to its outer edge. The wheels are positioned to oppose each other at an acute angle.

Abstract: A device for sharpening rotary blades driven about a fixed axis of rotation, as widely used in cigarette manufacturing machines, including a pair of mutually coaxial grinding wheels distanced one from the other, angled in relation to the plane occupied by the rotary blade, rotatable about a common axis and able to traverse toward and away from the blade. The grinding wheels are mounted to a shaft capable of movement through a rectilinear path parallel to the plane occupied by the blade and set in motion by a drive system interlocked to a monitoring and control medium that is automatic in operation and programmable according to the rate of wear or loss of cutting edge of the blade. Also forming a part of the device are sensors able to indicate when the blade is totally worn, i.e. when reduced to its minimum working diameter.

Abstract: A knife sharpening device having a base removably supporting a pair of grinding wheels at an acute angle to the horizontal. A housing encloses the base and includes a slot for receiving a knife edge, which when inserted in the housing will seat between the wheels. The wheels are biased into clamping engagement with the knife edge so that to and fro movement in the slot will cause the wheels to contact and grind the edge of the knife.

Abstract: A fine smooth finish can be obtained on blades without grinding by drawing them against a rotating hardened disk with a smooth peripheral edge. One or a pair of hardened disks having smooth, rounded peripheral edges being disposed adjacent to and partially received by knife-guiding structure, having rotation imparting drive. The use of smooth edged hardened disks enables a very fine finished edge to be obtained, similar to the edge resulting from the use of a hand held steel, and often better.

Abstract: The knife sharpener is comprised of a pair of cutting wheels carried for rotation by a supporting block. Each cutting wheel is rotatably journaled on an axle. Each axle has a bore extending therethrough. A fastener passes through the bores to secure the axles to the supporting block. At least one of the bores is eccentrically disposed within its axle. Rotation of the axle having the eccentric bore moves the rotational axis of the cutting wheel journaled thereon to adjust the clearance between the cutting wheels.
