Abstract
An expandable tool for laying out and marking predetermined angular layout lines on a work surface. The tool is comprised of a first leg (202), second leg (204), and hypotenuse leg (206) which are assembled by the user such that the intersection of the first and second leg form the desired angle as defined by the hypotenuse (206). The general shape of the assembled tool will normally be a triangle. Each leg of the tool can consist of a single leg portion (or member), or alternatively, each leg can be made up of more than one leg portion. The ends of each leg are fitted with a fastening mechanism (214) for connecting the leg portions together. The tool can be made to various sizes by the addition and deletion of leg portions. Additionally, the tool can be disassembled to facilitate compact transport to subsequent work sites.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
