Adjustable plumb level

An adjustable plumb level, comprising:

• an I-shaped structure having first and second opposite, flat sides, said I-shaped structure having an opening extending from said first to said second side;
• a receiver member coupled to said I-shaped structure and at least partially extending through said opening, said receiver member having a first annular wall defining a first space and a second annular wall defining a second space, said first space being connected to said second space via a break in the first annular wall;
• first gear means disposed in said first space, said first gear means being annular in form and having a level indicating mechanism disposed in the center thereof;
• second gear means disposed in said second space operatively coupled to said first gear means, said second gear means having a smaller outer diameter than an outer diameter of said first gear means;
• means for operatively coupling an external rotational force to said first gear means to change a position of said level indicating mechanism with respect to said I-shaped member, said operatively coupling means disposed on said second gear means;
• and
• means for maintaining the first and second gear means in said first and second spaces, respectively;
• wherein said indicating mechanism is rotatable about 360.degree. or any increment or multiple thereof.
