Tool grinder apparatus and method

A tool grinder comprising:

• a base including a vertical and a horizontal portion;
• a grinding assembly, said grinding assembly including a housing attached to the vertical portion of said base, a motor connected within said housing, a vertically oriented drive shaft driven by said motor and a grinding head connected to and driven by said drive shaft;
• a table mounted on said horizontal portion of said base, said table being slidable in one direction on a substantially horizontal plane with respect to said base wherein said table includes at least one releasable stop for setting the position of said table relative to said base;
• a first station for sharpening the blades of the tool, said first station including alternatively;
• a first pivotal sleeve stationarily mounted on said table whereby said slidable table causes said first sleeve to be selectively moved toward or away from said grinding head;
• a horizontally adjustable arm mounted on said first sleeve;
• a pointer slidably mounted on said arm at an angle acute to said arm;
• a guidepin vertically and supported by said first sleeve;
• a means for marking the centerline of an entire length of the blade of the tool to be grinded, said means for marking the centerline including said arm, said pointer, and said guidepin,
• a second station for sharpening the tip of the tool, said second station including:
• a track attached to said base;
• and
• a slide mounted on said track, wherein said slide is microadjustable with respect to said track.

A tool grinder comprising:

• a base;
• sharpening means supported by said base;
• a table slidably mounted on said base;
• a means for advancing the tool to be grinded by said sharpening means, said means for advancing being stationarily mounted on said slidable table;
• means for holding the tool to be grinded by said sharpening means, said means for holding being slidably mountable in said means for advancing;
• a cam mounted on said means for holding, said cam including a groove for indexing the tool to be grinded;
• a guidepin which slides in said groove of said cam, said guidepin being supported by said means for advancing the tool;
• an adjustable arm mounted on said means for advancing;
• a pointer mounted on said arm at an angle acute to said arm;
• and
• a means for marking the centerline of an entire length of the blade of the tool to be grinded, said means for marking the centerline including said arm, said pointer, said cam, said guidepin and said means for holding the tool.
