  • Patent number: 5810649
    Abstract: A tool guide for sharpening woodcarving and lathe tools comprises a holder frame having an adjustable clamping member for clamping a portion of a tool against an inner surface thereof, and an adjustable foot member removably connected to the holder frame by a downwardly extending central rod for engaging a work surface which is coplanar with or parallel to a nearby abrasive sharpening surface. The foot member includes an arcuate surface which may be arranged to engage the work surface for sharpening tools having a U-shaped cutting edge profile, and a pair of arc ends which may be arranged to engage the work surface by inverting the foot member for sharpening tools having a straight cutting edge profile. A pair of side rods are spaced on opposite sides of the central rod, whereby distal ends of the side rods and central rod define an angular profile for sharpening tools having a V-shaped cutting edge when the foot member is removed.

  • Patent number: 4514883
    Abstract: A belt buckle comprising a body adapted to be connected to a belt for wearing on a user and having a structure which simulates a known object having a movable component, for example an automobile, bell, or animal such as a bird. An element is movably connected to the body and located so as to be exposed to view when the buckle is worn on the user, and the element has a structure which simulates the movable component of the object, for example the automobile hood, bell striker or bird beak. An operator member is movably carried by the body and responsive to manual operation, and a motion transmission mechanism carried by the body and operatively connected to the element and to the operator member converts movement of the operator member in response to manual operation into movement of the element relative to the body. As a result, activity of the known object is simulated.
