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.

[ What is claimed is:] [1.] A knife sharpening machine comprising a housing, a stone assembly, carried by said housing, comprising a fixed subassembly, and a movable subassembly, each of said subassemblies having circular stones mounted on a shaft, spaced axially from one another, the axial space between the circular stones of each assembly being sufficient to admit one of the circular stones making up the other assembly, said assemblies being axially offset from one another to permit interleaving of said stones, adjusting means for moving said movable subassembly toward and away from said fixed subassembly, from a position at which they are tangent to one another to a position at which they are interleaved, means for rotating said subassemblies including a gear mounted at an end of each subassembly shaft remote from said stones carried by said subassembly, the shaft of the movable subassembly being mounted in a free end of a yoke pivotally mounted on said housing on an axis of rotation, and a gear mounted on said axis of rotation of said yoke, coaxially with said axis and operatively connected with said gear on said movable subassembly shaft, said adjusting means comprising an adjusting rod for selectively rocking said yoke around said axis of rotation to move one assembly toward and away from the other assembly, and a motor for driving said gears.
