Miter boxes

A miter box for holding a longitudinal workpiece to be cut by a cutting means at a first angle measured in a plane parallel to the longitudinal axis of said workpiece and at a second angle measured in a plane perpendicular to said longitudinal axis of said workpiece comprising

• a base,
• a cutting means guide mounted on said base for guiding said cutting means to cut said workpiece at said first angle,
• a first clamping means mounted on said base having a lower surface at said second angle to said base, and
• a second clamping means mounted on said base and having an upper surface at said second angle to said base, said second clamping means being moveable between toward and away positions from said first clamping means so that said workpiece may be positioned between said first and second clamping means and being engageable in said toward position to clamp said workpiece between said first and second clamping means.

A miter box for holding a longitudinal workpiece to be cut by a cutting means at a first non-right angle measured in a plane parallel to the longitudinal axis of said workpiece and at a second non-right angle measured in a plane perpendicular to said longitudinal axis of said workpiece comprising

• a base,
• a backboard mounted perpendicularly on one edge of said base,
• a cutting means guide for guiding said cutting means to cut said workpiece at said first angle,
• a first wedge means mounted on said backboard having a lower surface at said second angle to said backboard,
• a second wedge means mounted on said base and having an upper surface at said second angle to said backboard, said second wedge means being moveable toward and away from said backboard so that said workpiece may be positioned between said first and second wedge means and being engageable to said backboard to clamp said workpiece between said first and second wedge means when said workpiece is cut.

A miter box for holding a longitudinal workpiece to be cut by a cutting means at a first non-right angle measured in a plane parallel to the longitudinal axis of said workpiece and at a second non-right angle measured in plane perpendicular to said longitudinal axis of said workpiece comprising

• a base,
• a cutting means guide mounted on said base for guiding said cutting means to cut said workpiece at said first angle,
• a first wedge means mounted on said base having a standard perpendicular to said base and a lower surface hinged to said standard, a first plate extending from said standard toward said hinged lower surface having an arcuate slot having an arc of radius equal to the distance between said slot and said hinge, a second plate extending from said lower surface toward said standard having an arcuate slot having an arc of radius equal to the distance between said slot and said hinge of said first wedge means, so that said slots of said first and second plates substantially overlap, a bolt passing through said slot and a nut means on said bolt for tightening said first and second plate together, whereby said hinged lower surface may be secured at said second angle to said standard,
• a second wedge means mounted on said base and having a first surface parallel to said base, a second surface hinged to said first surface, a first plate extending from said first surface toward said second surface having an arcuate slot having an arc of radius equal to the distance between said slot and said hinge of said second wedge means, a second plate extending from said second surface toward said first surface having an arcuate slot having an arc of radius equal to the distance between said slot and said hinge, so that said slots of said first and second plates substantially overlap, a bolt passing through said slots and a nut means on said bolt for tightening said first and second plates together, whereby said hinged second surface may be secured at 90 degrees minus said second angle to said first surface, so that said workpiece may be clamped between said lower surface of said first wedge means and said second surface of said second wedge means when said workpiece is cut.
