Benefits of technology
"The present invention is a system for leveling a pole in a concrete block. The system includes four threaded bolts that are installed in the block and positioned in a circular configuration around it. Nuts are installed on each bolt and a washer may be added between the nut and the bolt. A plate is made of a rigid material, like aluminum, and has a central aperture and four slots that run from the central aperture to the edge of the plate. Each bolt is fitted into a separate slot with the edges of the slot either directly on the bolt or on a washer fitted on the bolt. A leveling gage is mounted on the plate. The nuts are adjusted in position to bring the plate into a level position. The tool plate is then removed for use on another installation. The system provides accurate level support for the pole."
Problems solved by technology
This is a rather tedious and time consuming operation and is readily subject to errors.

Embodiment Construction
[0015]The device and method of the present invention has many advantages over this prior art approach. First, the accuracy of the achieved level is greatly improved over the prior art approach which involves the use of a torpedo level to level from one bolt to the next. The use of the flat plate of the tool of the present invention with a circular level mounted on it allows a complete and accurate leveling in a simple operation, thereby minimizing the possibility of any error between the support points.
[0016]Further, by pre-leveling the bottom nut prior to pole installation, there is no need to leave a large gap for future adjustment. Recessing the bolts into the concrete allows the pole base direct contact with the concrete base with no resulting gap; or the nuts can be leveled closer to the concrete base, resulting in a smaller gap. By either minimizing the adjustment gap or eliminating it entirely, a much stronger and more structurally sound installation of the pole is obtained. ...

Four bolts in a square configuration are installed in a base member of concrete with the threaded portions of the bolts protruding above the surface of the base member. A nut is attached to each of the bolts and above the nut, a washer is installed. A leveling tool is in the form of a plate of a flat rigid non bendable material such as aluminum. The leveling tool has an aperture in its center and four slots which are spaced evenly from each other around the tool and extend radially away the central aperture. The bolts are each fitted into one of the slots with the edges of the slots abutting against the washers. A leveling gage is installed on the surface of the tool. The nuts are then adjustably positioned until the gage indicates that the tool is vertically level. The tool is then removed and the four bolts and washers used to provide a level support for the base of a pole or other vertical support structure.
Description
[0001]This Application is based on Provisional Application No. 60 / 900,002 filed Feb. 17, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention is related to vertically standing poles and columns and more particularly to a system and method employing a tool which employs nuts vertically adjustable on bolts to provide a level support for such poles and columns.[0004]2. Description of the Prior Art[0005]In the prior art, poles are generally leveled by installing four bolts in a concrete base spaced from each other as are the mounting holes in the base of the pole Nuts with washers over them are then installed on each of the bolts. The nuts on pairs of bolts are then successively vertically adjusted so they are level with each other with a Torpedo level which is placed between two nuts. This type of leveling operation is repeated with different pairs of nuts until all are indicated to be in a level state. The base of the pole is then mounted on the bolts an...
