Abstract:
A knife sharpening machine has sharpening and honing assemblies each having fixed and movable subassemblies with circular stones mounted on shafts, the stones being spaced from one another. An adjusting mechanism moves the movable subassemblies toward and away from the fixed subassemblies, from a position at which the stones interleave to one at which they are substantially tangent to one another. The movable subassemblies each includes a yoke in a free end of which the stone-carrying shaft is journaled for rotation. The yoke is pivoted on an axis of rotation. One gear is mounted on the axis of rotation of the yoke co-axially with the axis, driving a gear on the shaft of the subassembly carried by the yoke. A motor and gears of gear trains intermediate a pinion on the motor and the pivot gear are mounted on a plate mounted on a cast base/housing supporting the yoke. Sharpening and honing assemblies are both mounted on the one base/housing, and both are driven, at different speeds of rotation, through gear trains, by the same motor.
