BACKGROUND OF THE INVENTON
In the building trades, four types of measuring squares are well known. These include the Bevel Square, the Framing Square, the Tee-Square and the Speed Square. The Bevel Square includes an adjustable blade for transferring angles. The Framing Square includes a fixed, 90° blade for square alignments and for cutting layouts for roof and stair framing. The T-Square is primarily used for 90° off-edge marking and cutting of building materials. The Speed Square includes a fixed triangular shaped member that includes 45° and 90° angles for marking angled cuts in roof framing.
Although these four types of measuring squares of the prior art have proven useful, the utility of any one type of these squares is limited by its design to work with angles. Consequently, all four types of these squares do not directly assign a specific measurement to an angle. This causes added complexity in taking measurements and subsequent cutting of materials. A need therefore exists for a measuring square which overcomes these disadvantages and provides a tool that shows precise angle measurements.
SUMMARY OF THE INVENTION
The invention relates to a novel, multi-function measuring square that may be used to perform the functions of any of a Bevel Square, Framing Square, T-Square or Speed Square.
