Abstract

A blade sharpening apparatus for sharpening a serrated blade includes a blade holder configured to securely hold a serrated blade in a position that exposes a toothed edge of the serrated blade. A grinding wheel rotates about a rotational axis and engages teeth spaced along the toothed edge of the serrated blade that is secured in the blade holder. An oscillating mechanism laterally oscillates the blade holder or the grinding wheel relative to the other at an oscillating distance greater than a depth between the teeth on the serrated blade. A linear actuator longitudinally moves the blade holder or the grinding wheel relative to the other and substantially parallel with the rotational axis of the grinding wheel. The linear actuator is operable with the oscillating mechanism to coincide the longitudinal and lateral movement to correspond to the depth and spacing of the teeth disposed along the serrated blade.

Dependent claims

A blade sharpening apparatus for sharpening a serrated blade, said blade sharpening apparatus comprising:

a blade holder configured to securely hold a serrated blade in a position that exposes a toothed edge of the serrated blade;
a grinding wheel configured to rotate about a rotational axis and engage teeth spaced along the toothed edge of the serrated blade;
an oscillating mechanism configured to laterally oscillate one of the blade holder and the grinding wheel relative to the other at an oscillating amplitude that corresponds to a depth between the teeth on the serrated blade;
a linear actuator coupled with one of the blade holder and the grinding wheel and configured to longitudinally move substantially parallel with the rotational axis of the grinding wheel, wherein the linear actuator is operable with the oscillating mechanism to coincide the longitudinal and lateral movement to correspond to the depth and spacing of the teeth disposed along the serrated blade, and wherein the linear actuator comprises a threaded rod attached at a rotational coupling at an offset location from a central axis of the rotational coupling to provide the lateral oscillation;
and
a base structure stationary relative to the coinciding longitudinal and lateral movement provided by the respective linear actuator and oscillating mechanism, wherein the rotational coupling is rotatably coupled with an electric motor that is supported at the base structure.
