Hand tool leveling apparatus

Apparatus for leveling a tool having a working axis comprising:

• a receptacle of a predetermined configuration attached to the tool;
• an elongated, sealed, transparent cylindrical tube containing a liquid and a bubble formed by the liquid, said tube being mounted in the receptacle with its horizontal axis parallel to the working axis of the tool to level the tool in a horizontal plane, the receptacle being configured so as to enable viewing the bubble in the cylindrical level from at least the top and both sides thereof.
• a circular bubble level mounted in the receptacle having an axis passing perpendicular through the center of the circular level, said axis being disposed parallel to the working axis of the tool for leveling the tool in a vertical plane, said circular level containing a transparent liquid and a bubble formed by the liquid, said circular level being biconvex in cross-section and positioned in the receptacle whereby the bubble can be properly positioned in the level to level the tool in either the vertical upward or vertical downward positions and the circular level retains the cylindrical level in the receptacle;
• and
• resilient means for removably locking the circular bubble level within the receptacle.
