  • Patent number: 5078029
    Abstract: A grinding machine for sharpening toothed saws includes a saw blade holder for rotatably holding a saw. A pneumatic or hydraulic ram drives a cam back and forth in one of a number of preselected grooves in a rotatable cam plate for driving a pawl in an arcuate path for rotating the saw blade. Each saw tooth is thus advanced, one tooth at a time, through a grinding position in which a rotating grindstone sharpens the face or top of the saw tooth. The position of the grinder head arm is adjustable through an arc of about 105.degree. to permit top and face grinding without turning over the grindstone or the spindle arm on which the grindstone is mounted. The head arm is tiltably mounted on a heavy plate and releasably secured to the periphery of the plate for stability.
