The present invention is a new multipurpose speed square that is easily utilized by any workman who typically requires a means for measuring, aligning, leveling, etc. The speed square is multi-functional, of simple construction, lightweight and portable. The speed square can be easily carried as an all-in-one tool and thus eliminates the need for additional tools, or the like. The speed square that can be manufactured from substantially any suitable material of engineering choice, is cost effective to produce, manufacture, easily marketed and easily sold.

An adjustable T-square device and method of use is shown and described herein. The adjustable T-square has a plurality of apertures with at least one locking detent to set precise angles. The adjustable T-square has a locking pin to further engage a ruler portion to a head portion to minimize error when using the device.

Embodiments described herein are directed to an apparatus for determining a direction in which a tree will fall and a method for using the apparatus. The apparatus may comprise a plate including a substantially straight edge suitable for alignment with a vertex formed by a top cut and a bottom cut of a notch cut into a tree and a substantially level bottom surface suitable for stable placement upon the bottom cut of the notch. In some embodiments, the plate may define an internal cavity sized to accommodate a laser light generator. In other embodiments, a rotatable housing including a cavity sized to accommodate a laser light generator may be adjoined to the plate. Embodiments may permit a laser light generator contained within the cavity or the housing to emanate a beam of laser light in a direction that is substantially perpendicular to the substantially straight edge of the plate.

An adjustable square has a blade including a scale, a body, a slot formed in the body for movably receiving the blade, a locking mechanism operably engaged with the body for releasably securing the blade within the slot, and an indexing member operably engaged with the body and operably engaged with the blade. The indexing member indexes the body at precise locations along the blade. A method for indexing an adjustable square is also provided. The method includes positioning a body of the adjustable square at a precise known position and indexing, with an indexing member of the adjustable square, the body of the adjustable square at the precise known position.

A speed square is provided including a triangular flat plate having measurement markings indicated on at least one face, a T bar affixed to, and extending along, the length of a first side of the triangular flat plate, and an extension element hingedly connected to an end of second side of the triangular flat plate opposite the T bar. The extension element having measurement markings indicated on at least one face, such that the measurement markings of the triangular flat face continue on the extension element.

A templating device for preparing beams includes a rod that has opposed ends, each of which is both slidably engageable and fixedly engageable to a first segment of a respective protractor of a pair of protractors, such that the first segment extends linearly from the rod. The first segment is pivotally engaged to a second segment, which is selectively fixably positionable relative to the first segment. The rod and the first segments are positioned between a pair of surfaces, with each second segment positioned flush to a respective surface. A user fixes the second segment relative to the first segment to provide a respective angle measurement and a length measurement between the surfaces, and then templates these measurements onto a beam. The user then can cut the beam to length, with the ends of the beam angled so that the beam fits between the pair of surfaces.

A speed square is provided including a triangular flat plate having measurement markings indicated on a least one face, a T bar affixed to, and extending along, the length of the first side of the triangular flat plate, and an extension element operably coupled to an end of second side of the triangular flat plate opposite the T bar. The extension element having measurement markings indicated on at least one face, such that the measurement markings of the triangular flat face continue on the extension element.
